Gut bacteria linked to muscle function in the colon, says mice study – NutraIngredients.com

Researchers fromCrick University in London and the University of Bern in Switzerland have identified how the contraction and relaxation of muscles in the colon, which is regulated by nerve cells, is influenced by the bacteria in our gut.

The study, published inNature,when such microbes are present, a specific gene called Ahr is activated in intestinal nerves, resulting in healthy contraction and relaxation of the colon. This relationship can be disrupted in cases of intestinal disorders, like irritable bowel syndrome (IBS).

"There is a clear link between the presence of microbes in the colon and the speed at which food moves through the system. If this relationship goes off-kilter it could cause considerable harm," says Yuuki Obata, lead author and postdoc in the Development and Homeostasis of the Nervous System Laboratory at the Crick.

The study help explain how nerve cells sense the microbes in the gut and how they could coordinate their function with other gut tissues.

"Disturbances of intestinal motility are extremely common and cause a lot of suffering in patients after surgical operations or in conditions such as irritable bowel syndrome,"explains Andrew Macpherson, Professor of Medicine and Director of Gastroenterology at the University Hospital of Bern.

"This work provides a foundation to unravel why patients that are colonised with different groups of microbes are susceptible to these intestinal problems."

Brigitta Stockinger, co-lead author and group leader in the AhRimmunity Laboratory at the Crick, adds:"By drawing on different teams at the Crick and internationally with Bern University, we've combined expertise on the gut and how environmental signals from microbiota and diet are passed to cells, to gain understanding of how gut physiology and digestion are affected by these signals."

Vassilis Pachnis, co-lead author and group leader in the Development and Homeostasis of the Nervous System Laboratory at the Crick, adds that this is the first study to demonstrate howAhR is used by intestinal nerve cells to sense the presence of microbes and regulate peristalsis therefore promoting healthy digestion.

He adds: "Inthe future, the use of microbial products that change the activity of AhR in nerve cells could help us alleviate the consequences of abnormal gut peristalsis that is often associated with gastrointestinal diseases."

Designer wants to push the limits of human performance in space – AroundtheO

Olivia Echols says her dream job probably doesn't exist yet because it's so futuristic. But the graduate program in sports product design at the University of Oregon Portland is helping her prepare for it.

From 3D body scanning and computer-aided design to physiology and biomechanics, the program gave her a wide range of knowledge and experience in the world of design. Echols graduated in June 2019 and has been working on the Future Design Team at Adidas.

Echols grew up with a love for sewing and making her own clothes, which inspired her to pursue a career in designing apparel. After earning her bachelors degree in apparel design from Oregon State University in 2013, she worked at Nike in technical design and materials innovation for four years.

She decided to go into the sports product design graduate program in order to further develop her skills and shift her career back to design.

I wanted to grow my process and aesthetic and see whats possible, Echols said.

Echols said getting her masters at UO Portland has been invaluable, as shes currently in a design position helping the team at Adidas come up with concepts for items that will reach the market in five to seven years.

Its a different perspective to have gone back to school and now be working again, Echols said. It felt like a reset, and I feel like a stronger designer for it.

The program went beyond apparel and taught Echols and her classmates how to design just about anything for athletes, from footwear and transportation to gloves. They also got to work with the latest technology, including software programs, scanners, 3D printers, laser cutters, vacuum forming machines and more.

Susan Sokolowski, the program director and an associate professor of sports product design, said developing future female and minority design innovation leaders is important to the graduate program, as the sports industry has historically been focused on male leaders and products for men.

Olivia represents the next generation of design innovators. She is an amazing teammate, incredible maker and thinker, Sokolowski said. We support our students to develop their why and point of view of how they can change the industry with new products for untapped markets and users.

For Echols, those physical environments are not limited to Earth.

For her capstone project, Echols designed and produced workout apparel meant for astronauts in space, taking physiology and biomechanics into account. During her spring break last year, she even went to space camp in Houston to learn more about how to design for the way bodies change and perform in space.

The program also gave her opportunities to travel internationally. She and a classmate were selected as finalists in the Woolmark Performance Challenge, a competition for early career designers to develop creative sports products with merino wool. Echols got to travel to London for a workshop at the Woolmark offices.

It was super cool and inspiring, and theres so much going on there, not only in fashion but on the tech side, Echols said. She also got to pitch her ideas to a panel of professionals at a conference in Denver called Outdoor Retailer.

Kiersten Muenchinger, an associate professor of product design in the School of Art + Design, said the graduate program is the only one in the world thats focused on the design and innovation of sports industry products like footwear, apparel and equipment.

Portland is the international hub of design innovation in sports product, Muenchinger said. Both Nike and Columbia Sportswear developed in the Portland area and inspired many international and local brands to follow.

Muenchinger called Echols a leader.

She is comfortable innovating by conducting her own research and applying materials and manufacturing innovations in the areas she researches, Muenchinger said.

Muenchinger said she hopes Echols and the other sports product design students and alumni continue to innovate to help people perform at their peak, in whatever physical environments they encounter.

Echols is inspired to push the boundaries of human performance on Earth and in space.

Its exciting to be entering the industry right now as a woman because I think theres a renewed sense of creating products for women, and Im excited to work at companies with women in leadership roles, she said.

Scientists Reverse Age-Related Thinking Problems in Mice by Tinkering With Immune Cells in Their Brains – Newsweek

Scientists have reversed age-related thinking problems in mice by tinkering with their immune cells, in work they hope could one day help people with Alzheimer's disease and other forms of dementia.

Our cognitive abilities are thought to decline with age because of changes to our brains, such as a decline in grey matter, as well as the potential effects of medications and health problems

The latest study focused on a type of immune cell called group 2 innate lymphoid cells (ILC2s), which help to repair parts of the central nervous system such as the spinal cord.

In the brains of youngtwo to three-month-oldand older18 to 22-month-oldmice, the researchers found ILC2s collected in a part of the brain called the choroid plexus, a specialized brain barrier structure. This sits near the hippocampus, which is key for learning and memory.

In older mice, the team of immunologists and neuroscientists discovered five times as many ILC2s when compared with the younger mice, and that in older mice, these cells were less active.

The team then used a special molecule to reawaken the inactive ILC2s in older mice, and put the animals through a series of tests to see if their cognitive skills had improvedwhich they did.

The scientists also found a collection of ILC2s in the choroid plexus in brain autopsies of humans over than 65-years-old.

Kristen L. Zuloaga of Albany Medical College, co-author of the paper published in the Journal of Experimental Medicine, told Newsweek their study is the first to identify ILC2 cells in the choroid plexus. "We further discovered that these cells accumulate with aging. Strikingly, these aging-associated ILC2s are capable of improving brain physiology and reducing aging-associated cognitive decline," she said.

Zuloaga acknowledged the study was limited because the work was based largely on mouse models, and the team are yet to investigate the immune cells in human patients with neurodegenerative diseases.

However, the team said they were surprised at the findings.

The study's first author, Ivan Ting Hin Fung, of the department of immunology and microbial disease at Albany Medical College, told Newsweek: "Little is known about the roles immune cells play in brain physiology and function and how they influence aging-associated neurodegenerative diseases like Alzheimer's disease."

They hope the study will help with the development of new ways of combating Alzheimer's disease and other forms of dementia that are related to age. Currently, there are no treatments for Alzheimer's disease, which an estimated 5.8 million Americans are living with.

Richard Siow, director of Ageing Research at King's College London in the U.K. who did not work on the study, told Newsweek experts already knew that learning and memory decline with age, along with adaptive immunitywhich in turn makes a person more susceptible to infectious diseases.

"However, this study represents the first demonstration that immune cells can also affect cognitive function in mammals," he said. "The activity of immune cells with aging compensates for decline in adaptive immunity, leading to increased chronic inflammation but this study shows that populations of immune cells with enhanced resilience can combat aging processes."

He stressed that the study was limited because it was largely conducted in mice and "human cognitive ability and mechanisms of age-related brain diseases are very different."

"Further human based studies are necessary to validate these findings. Human tissues were collected from deceased elderly people so not representative of those with earlier stages of cognitive decline," he explained.

Siow said further research exploring ICL2 and the molecule the researchers harnessed will give new insights for the mechanisms of brain aging. This should help the development of strategies to delay the onset of cognitive decline, as well as regenerative therapies to treat brain disease associated with ageing.

The biology, function, and biomedical applications of exosomes – Science Magazine

Clinical uses of cellular communication

Exosomes are a type of extracellular vesicle that contain constituents (protein, DNA, and RNA) of the cells that secrete them. They are taken up by distant cells, where they can affect cell function and behavior. Intercellular communication through exosomes seems to be involved in the pathogenesis of various disorders, including cancer, neurodegeneration, and inflammatory diseases. In a Review, Kalluri and LeBleu discuss the biogenesis and function of exosomes in disease, highlighting areas where more research is needed. They also discuss the potential clinical applications of exosome profiling for diagnostics and exosome-mediated delivery of therapeutics to target disease cells.

Science, this issue p. eaau6977

All cells, prokaryotes and eukaryotes, release extracellular vesicles (EVs) as part of their normal physiology and during acquired abnormalities. EVs can be broadly divided into two categories, ectosomes and exosomes. Ectosomes are vesicles that pinch off the surface of the plasma membrane via outward budding, and include microvesicles, microparticles, and large vesicles in the size range of ~50 nm to 1 m in diameter. Exosomes are EVs with a size range of ~40 to 160 nm (average ~100 nm) in diameter with an endosomal origin. Sequential invagination of the plasma membrane ultimately results in the formation of multivesicular bodies, which can intersect with other intracellular vesicles and organelles, contributing to diversity in the constituents of exosomes. Depending on the cell of origin, EVs, including exosomes, can contain many constituents of a cell, including DNA, RNA, lipids, metabolites, and cytosolic and cell-surface proteins. The physiological purpose of generating exosomes remains largely unknown and needs investigation. One speculated role is that exosomes likely remove excess and/or unnecessary constituents from cells to maintain cellular homeostasis. Recent studies reviewed here also indicate a functional, targeted, mechanism-driven accumulation of specific cellular components in exosomes, suggesting that they have a role in regulating intercellular communication.

Exosomes are associated with immune responses, viral pathogenicity, pregnancy, cardiovascular diseases, central nervous systemrelated diseases, and cancer progression. Proteins, metabolites, and nucleic acids delivered by exosomes into recipient cells effectively alter their biological response. Such exosome-mediated responses can be disease promoting or restraining. The intrinsic properties of exosomes in regulating complex intracellular pathways has advanced their potential utility in the therapeutic control of many diseases, including neurodegenerative conditions and cancer. Exosomes can be engineered to deliver diverse therapeutic payloads, including short interfering RNAs, antisense oligonucleotides, chemotherapeutic agents, and immune modulators, with an ability to direct their delivery to a desired target. The lipid and protein composition of exosomes can affect their pharmacokinetic properties, and their natural constituents may play a role in enhanced bioavailability and in minimizing adverse reactions. In addition to their therapeutic potential, exosomes also have the potential to aid in disease diagnosis. They have been reported in all biological fluids, and the composition of the complex cargo of exosomes is readily accessible via sampling of biological fluids (liquid biopsies). Exosome-based liquid biopsy highlights their potential utility in diagnosis and determining the prognosis of patients with cancer and other diseases. Disease progression and response to therapy may also be ascertained by a multicomponent analysis of exosomes.

The study of exosomes is an active area of research. Ongoing technological and experimental advances are likely to yield valuable information regarding their heterogeneity and biological function(s), as well as enhance our ability to harness their therapeutic and diagnostic potential. As we develop more standardized purification and analytical procedures for the study of exosomes, this will likely reveal their functional heterogeneity. Nonetheless, functional readouts using EVs enriched for exosomes have already provided new insights into their contribution to various diseases. New genetic mouse models with the ability for de novo or induced generation of cell-specific exosomes in health and disease will likely show the causal role of exosomes in cell-to-cell communication locally and between organs. Whether exosome generation and content change with age needs investigation, and such information could offer new insights into tissue senescence, organ deterioration, and programmed or premature aging. Whether EVs and/or exosomes preceded the first emergence of the single-cell organism on the planet is tempting to speculate, and focused bioelectric and biochemical experiments in the future could reveal their cell-independent biological functions. Single-exosome identification and isolation and cryoelectron microscopy analyses have the potential to substantially improve our understanding of the basic biology of exosomes and their use in applied science and technology. Such knowledge will inform the therapeutic potential of exosomes for various diseases, including cancer and neurodegenerative diseases.

Exosomes are extracellular vesicles generated by all cells and they carry nucleic acids, proteins, lipids, and metabolites. They are mediators of near and long-distance intercellular communication in health and disease and affect various aspects of cell biology.

The study of extracellular vesicles (EVs) has the potential to identify unknown cellular and molecular mechanisms in intercellular communication and in organ homeostasis and disease. Exosomes, with an average diameter of ~100 nanometers, are a subset of EVs. The biogenesis of exosomes involves their origin in endosomes, and subsequent interactions with other intracellular vesicles and organelles generate the final content of the exosomes. Their diverse constituents include nucleic acids, proteins, lipids, amino acids, and metabolites, which can reflect their cell of origin. In various diseases, exosomes offer a window into altered cellular or tissue states, and their detection in biological fluids potentially offers a multicomponent diagnostic readout. The efficient exchange of cellular components through exosomes can inform their applied use in designing exosome-based therapeutics.

Beat the heat in poultry production – All about feed

Hot, hotter, heat stress. Climate change with its rising temperatures is increasingly becoming an intense stress factor in animal production. In the summer months, outside temperatures can quickly reach highs of over 35C this means it can get hot in the poultry house.

Modern broiler breeds have a continuously increasing growth rate and feed efficiency, which coincides with a reduced heat tolerance. Housing broilers at high ambient temperatures adversely affects performance, intestinal integrity, immune response, and meat quality. In order to avoid heat-related performance losses, it is advisable to apply some nutritional practices, such as the addition of phytogenic feed additives, alongside other management practices to alleviate the negative consequences of heat stress.

Heat stress is an important environmental challenge for the livestock industry, especially in newly industrialising countries in the (sub)tropics. In the US, the costs of heat stress amount to more than US$160 million per year. The condition of heat stress occurs when animals are unable to lose their body heat due to high ambient temperature in combination with high relative humidity, resulting in unfavourable consequences that range from discomfort to increased mortality. The impact of heat stress depends on several factors including age and genetics, health status, nutritional status, and rearing conditions.

As long as the ambient temperature is lower than the body temperature of the birds, the heat loss from the core to the skin can be increased by radiation by varying the peripheral blood flow. However, if the ambient temperature exceeds the body temperature, the bird loses the ability to give off heat through radiation and the core body temperature increases. Unlike mammals, birds do not have sweat glands hence they are unable to sweat. Birds can lower their body temperature through panting and beak breathing.

Heat stressed animals change their behaviour and physiology to dissipate heat and maintain body temperature. Especially reduced feed intake is one of the first noticeable consequences of heat stress. Commercial broilers are particularly susceptible to heat stress, as their metabolic heat production is relatively high compared to other livestock.

Housing poultry at high ambient temperatures in combination with high humidity not only impairs production performance but also has negative effect on intestinal integrity, immune defence and meat quality. Inside the animals body, heat stress challenges the antioxidant defence systems and reduces the intestinal integrity.

Dry heat or a combination of high temperatures and high humidity causes a variety of behavioural, physiological and immunological changes in poultry. Thus, there are short and long-term negative effects on the immune system, as well as on the welfare, productivity and ultimately health of the animal. The reduction of feed intake is one of the first notable effects of heat stress in poultry. This reduction in feed intake during heat stress accounts for around 90% of the reduced weight gain. In acute stress situations, the synthesis of corticosterone, adrenaline and noradrenaline is also increased, resulting in enhanced muscle activity, increased respiration and blood glucose levels.

These increased plasma cortisol levels stimulate muscle breakdown and lipid peroxidation in muscle tissue, which is reflected in high levels of malondialdehyde (MDA) in the breast muscle of broilers, for example. In addition, the released stress hormones reduce the release of steroids and gonadotropins, resulting in reduced follicular development in hens. Moreover, studies show that the synthesis and release of vitellogenin, which is necessary for the deposition of egg yolk, is suppressed during heat stress. Also, the activity and efficiency of lymphatic organs such as bursa, spleen and thymus are impaired, resulting in impaired immune response in poultry. Furthermore, it has been shown that hyperventilation or panting to dissipate body heat leads to an increased release of CO2, which is necessary for the synthesis of calcium carbonate for egg shell formation. Heat stress has also been shown to increase blood pH and disturb the acid-base balance. This change in the acid-base balance can have negative effects on cardiac muscle activity and bone density.

Further investigations have shown that heat stress also impairs intestinal activity causing increased activity of the gastrointestinal tract, resulting in mild diarrhoea and electrolyte imbalance. Heat stress is also associated with increased lipid peroxidation in the enterocytes: chronic heat stress and associated oxidative stress lead to an overloading of the bodys anti-oxidative mechanisms, thus compromising intestinal integrity. Reactive oxygen species (ROS) also known as free radicals produced during oxidative stress, attack the intestinal mucosal cells and may lead to increased inflammation.

It has also been suggested that heat shock proteins (HSP70, a group of highly conserved protective proteins involved in cell protection and repair) play an essential role in alleviating heat stress by stimulating the activities of antioxidant enzymes and reducing oxidative damage in intestinal mucosal cells during heat stress. As a result, the intestinal epithelia may become increasingly permeable, the digestibility of nutrients decreases and the loss of water from the gut increases. This leaky gut can lead to an increased translocation of bacterial toxins, antigens and bacteria into the bloodstream, triggering the immune system and increasing stress on detoxifying organs especially the liver. As a result, animal performance suffers. But it is not only growth performance that is impacted by heat stress food safety may also be impaired. Due to increased cellular turnover and reduced intestinal integrity, pathogenic bacteria such as Salmonella enteritidis can pass the intestinal barrier and enter the body tissues. This poses a significant risk to food safety and therefore consumer health. However, it has also been suggested that heat shock proteins (HSP70, a group of highly conserved protective proteins involved in cell protection and repair) play an essential role in alleviating heat stress by stimulating the activities of antioxidant enzymes and reducing oxidative damage in intestinal mucosal cells during heat stress.

In addition to the optimisation of feed composition and structure, several (classes of) feed additives have been investigated to mitigate (the consequences of) heat stress. The efficacy of such additives is mainly directed towards their antioxidative effect. Heat stress in particular, induces oxidative processes in enterocytes, as described earlier. Increased amounts of dietary antioxidants, such as a combination of vitamins A and E, are able to reduce lipid peroxidation during heat stress. Furthermore, the addition of vitamin E improves the immune response of heat-stressed broilers.

Moreover, the non-essential amino acid glutamine has also been shown to increase the expression of HSP70 in the jejunal mucosa after acute heat stress, thus protecting it from oxidative stress, in addition to improving growth and meat quality.

Although the effects of nutrient concentration on the heat load of broilers are limited, an increased nutrient concentration of the feed, for example in the form of high-quality pellets, can also reduce the energy necessary for nutrient uptake. In addition, by limiting excess protein and optimising the amino acid profile, the metabolic energy costs associated with excess nitrogen excretion can be minimised. However, the optimal amino acid profile for heat stress conditions is not yet known.

Phytogenic feed additives (PFAs) are a valuable tool to meet current and future challenges in animal production. Many plants (e.g. thyme, oregano) and their active substances show effects that can maintain intestinal integrity and support the antioxidative capacity of the body, especially under heat stress. These mechanisms lead to the maintenance of a normal health status so that the bird can fully exploit its genetic potential.

Many aromatic plants, especially those of the Labiatae family (e.g. rosemary, thyme, oregano and sage), have been extensively studied for their antioxidant and anti-inflammatory properties. For example, thyme oil improved intestinal antioxidant status, reduced MDA content in the enterocytes and improved intestinal integrity. These activities are not only related to the phenolic compounds but also the non-phenolic compounds. These may show considerable anti-oxidative and anti-inflammatory activities by stimulating the detoxification of generated reactive oxygen species during stress. This is via either directly scavenging free radicals or indirectly by upregulating the expression of antioxidant and anti-inflammatory genes resulting in the production of antioxidant enzymes and anti-inflammatory proteins.

Besides limiting the oxidation-inflammation cascade, assorted essential oils have been shown to stimulate heat shock proteins that significantly contribute to the preservation of the intestinal barrier by inducing repair processes and improving cellular defence mechanisms. Moreover, it was shown that assorted pungent substances and essential oils have the ability to enhance the secretion of digestive juices and to stimulate nutrient transport from gut lumen to bloodstream, resulting in improved feed conversion. Additionally, assorted phytogenic ingredients support feed intake and nutrient digestibility and thus maintain high performance even during periods of heat stress.

A phytogenic feed additive (Biostrong Comfort) containing essential oils, flavonoids and pungent substances, spices and saponins has shown to improve the performance of broilers under heat stress conditions (Figure 1). A study conducted on 576 broilers (6 repetitions of 32 birds each; duration 42days) showed an increase in body weight of 5.2%, an increase in feed intake of 2.1%, and a reduction in FCR of 2.0% under cyclic heat stress conditions (8h at 32C, 12h at 26C, plus daily adjustment times; day 1-42 of age).

In terms of improving digestibility and performance even under heat stress, phytogenic feed additives have the potential to become a new generation of feed additives for innovative animal nutrition and welfare. They should be a decisive instrument to counteract heat stress and thus contribute to profitable animal production.

The Best Ingredient When Growing A Startup – Thrive Global

I love the term ingredients. It sounds delicious and smooths out the rough sound of technical terms. Growing a startup needs a lot of ingredients, and if youre looking from the entrepreneurs point of view, the list of them should be generous. I mean there are so many ingredients that can set you up for success or failure that a seasoned entrepreneur becomes a complicated dish.

Since my orientation is the mindset, we wont talk about paperwork and bureaucracy. Those are must-haves, unavoidable, fixed stuff. Those are the same for each with country variations of course. But you in your own field in your country will deal with the same steps as others. That wont differentiate you much.

But your mindset will. Because it gives you all those trump cards which can set you apart as a successful company or another failed one.

Going through multiple startups myself and having one right now I must say I went through all those dark roads faced by most of the entrepreneurs. If not all. There are of course several tips and tricks about entrepreneurship and how can you have a promising start.

This time though I want to point out my number one skill Ive learned during all these years that I consider right now the number strength to have as soon as possible; even though if you are young it can be challenging. But if you integrate this into your mindset, youre up to something amazing.

Lets name this power ingredient, the saffron of entrepreneurship. Its called thick skin. Yeep. I cannot imagine anything more important for me now than this. Everything else can be handled if you have your thick skin on.

Because lets see. Any startup is like a complex puzzle, you can see the final picture, but you still need to connect the parts. Right? When you start out you have infinite things to do, handle, overcome. Going through all those initial steps where to your max frustration many are not in your power, you just need to treat them to start the right way.

Then you need to find and blend a team in case youll have employees. Then you need to set up an infrastructure, a rhythm. A complex machine that can work in good order, otherwise, youre just an adventurer, and your startup is a jungle, it can eat you up pretty soon.

Lets name some of the challenges. Shall we?

Your perfect timing for each step faces set back independent of you. Papers are not ready in time, you missed a couple of details no one told you about. Youre envisioning the final part, and yet youre struggling with small details that were never even in your mind.

The road gets longer, and you lose yourself in peculiar tasks. You do have help but, those who are meant to do their part are not involved as you do, so for them, nothing is an emergency. Its not their company. So? You need to step up your personal leadership.

Same with your initial team. Youre dreaming about finding the best people and create a positive picture of everyone you meet. Youll soon find out that finding the right people has nothing to do with CVs, talent, or skill. Its a complex mix that needs to suit you as a person, the entrepreneur.

They need to share the same values; otherwise, theyll become a pain, you know where. Staring over with new employees, learning from your mistakes is not an easy pie. You do it anyway. Some sooner, some delaying the agonizing moment.

All these hustles wear you out, and you get yourself further apart from your dream. They are exhausting. There are moments when you forget why you are doing this. Those are the real struggles of an entrepreneur at the beginning.

Not to mention, since your business is new, no one acknowledges you like a big shot. So youre not important to anyone. And so you face also attitudes, humiliation, secret smiles behind your back. People who dont share your vision doesnt understand it. Youre being ridiculed, many times by your close friends or family. Even your new employees are acting like they are all God. How embarrassing. Right?

You didnt prove anything yet, youre just starting. And seeable improvements are nowhere around in one week, one month or six months. Can you see why many businesses fail before they start?

But thats no wonder because the school doesnt teach you how to become an entrepreneur. If anything, it teaches you the opposite. How to play within the lines, how to comply, when entrepreneurship has nothing to do with any of these.

And so, the thick skin comes into play. I repeat. If you can learn this early in life, you are so much ahead of the vast majority. I can guarantee you this. How to gain think skin.

You need to become your best friend. We all need to rely on someone. But when we start a business many times is no one who can envision 100% percent of what we are up to. Or they dont believe in you, or your plan. It doesnt even matter.

What you need is to erase all those factors out of your control. As many as you can. If you cannot delete the legal steps and everything I said before, you can erase the expectations from others. Dont expect them to sustain you, to help you, to trust you. Just dont. But you also need someone to rely on the right? Yeep. Its you.

So make a commitment to become your best friend and never let yourself down. You can count on yourself. You see the big picture. Youre the most competent one for the job.

Every time when something goes in the wrong direction or someone treats you like youre nothing, turn to your best friend. You. Tell him or her, Hey, chill, they dont see what you see. Nothing that happens right now wont determine the final outcome. You can take it. Its your dream. Make it happen. Who laughs at last laughs harder? Or best revenge success. Or any other motivational quote that inspires you.

If you want my current mindset in such instances, for me any setback gives me 10 times the energy because it makes me stronger. Im like, Ok so this happened. Or, ok, so you do this now to me. Well, thanks. Now I am actually busy to prove you wrong. I dont even care to prove anyone wrong anymore, but sounds powerful. Its about, I have other things to do to lose my time in this situation.

If something is more sensitive or painful, I shake myself, breathe, slow down a bit to relax and think, than go full gear ahead.

Its about the thick skin I grew on the way. You can touch me, but it wont last. I mean, you can still make me feel in a negative way, but that effect can last max 10 minutes in the worst-case scenario. Seriously. You need to do a lot of damage to make me lose myself for more than 10 minutes.

Anyone can do it. Im not Gary Vee to not be touched at all. My education was a bit different, to say it mildly. I still care, but 1% compared to how I cared 20 years ago. And Im working on my zero percent. Ill get there, trust me.

If youre determined to get rid of something or improve in any area, you can with discipline and conscious work. As soon as you feel hit by something, the first thing is to acknowledge it, expose it to yourself, your best friend. Everything exposed loses its power. This is so true. Amazingly true.

So, expose it first consciously. Look at it, analyze it like you have a microscope. Think about it like a foreign object, something that is not you, its an infection you can treat. Ok, this sounds a bit morbid. Its an alien object which altered your optimal state.

Then comes a chit chat with your best friend. Where youre talking about the final goal, vision, missionDo you remember my friend where you wanna go? Youre on the way but still not there. So its normal to face different landscapes. This is one. Just move forward and let this place behind. Go closer to your goal. Noone and nothing can stop you without your will. Make yourself accountable for everything.

This comes with a thick skin package. Because having a thick skin means somehow you created a circumstance where this noise, set back could enter in your plan. Expose it, learn from it, and move forward.

The most powerful method to achieve anything in life, including thick skin, is to be in control of your states. Your state is designed by emotions and physiology. As soon as you can control your emotions and physiology youll control your behavior because the behavior is the ultimate visible part of whats going on inside your mind which translates in emotions and body language.

And depended on your feelings you will act. Once your thick skin is in place, your inner state will be something like chill, cool, under control, under your control. And as you can presume the physiology for such a state is a straight back, heads up or horizontal, slow deep breathing, laser vision into the future.

Another quick and super-efficient way to alter your state in the right direction is to search YouTube about your issue. In 10 minutes with the right video or videos, you should be ready to roll. Ok, if you need more no problem. Youre doing something, youre acting the right way, not letting your state to put you down into a depression.

As long as you keep a state in your life, as powerful it is. So why not shake the bad states as soon as possible and take over with the right states shaping the powerful mindset with that think skin on top which will lead you anywhere, without fail.

Ok. So I hope I gave you the inspiration to boost yourself up and start building your startup without letting anything and anyone to eat up your energy and make you give up.

Its also helpful to know that similar to my story or ideas, you are not alone. Every startup entrepreneur went through a certain kind of hell. Its unavoidable. Unless youre living in a Lala Land in which case professional help is needed.

Otherwise, its just part of the journey. And with thick skin, the journey can even become fun, because this time youre armed with the right mindset, attitude, behavior gaining total control as the final cherry on the pie.

Abstract: Melatonin is a pleiotropic hormone synthesized and secreted mainly by the pineal gland in vertebrates. Melatonin is an endogenous regulator of circadian and seasonal rhythms. Melatonin is involved in many physiological and pathophysiological processes demonstrating antioxidant, antineoplastic, anti-inflammatory, and immunomodulatory properties. Accumulating evidence has revealed that melatonin plays an important role in pain modulation through multiple mechanisms. In this review, we examine recent evidence for melatonin on pain regulation in various animal models and patients with pain syndromes, and the potential cellular mechanisms.

Drug to improve fetal growth may increase blood pressure and blood sugar levels in offspring – News-Medical.net

Research suggests that a drug recently assessed as a potential treatment for fetal growth restriction may cause high blood pressure and raise blood sugar levels in offspring. The study, which urges practitioners to consider both short- and long-term effects when treating people with this pregnancy complication, is published in the American Journal of Physiology-;Heart and Circulatory Physiology. It was chosen as an APSselect article for February.

Fetal (intrauterine) growth restriction is a condition in which an unborn baby is not growing to its full potential in the womb. Babies with fetal growth restriction have a lower-than-average birth weight and much higher risk of being stillborn. The condition is difficult to treat, in part because many medications carry the potential risk of damage to the fetus.

Sildenafil citrate-;a vasodilator most often used as a treatment for erectile dysfunction-;has recently been tested in international clinical trials in severe cases of fetal growth restriction. The results did not show the beneficial effect of fetal weight gain. "The focus of previous studies has been to assess [sildenafil citrate's] effects on the mother, fetus and in some cases, [newborn], but only one study has examined the effects of antenatal [sildenafil citrate] in the long term," researchers of the current study wrote.

To learn more about how sildenafil citrate affects offspring after birth, the researchers studied a mouse model of fetal growth restriction. One group of female mice received daily subcutaneous injections of the drug-;equivalent to a human dose-;during pregnancy ("treated"), while another group was left untreated ("control"). The research team then measured blood pressure, body weight and blood sugar levels of the pups born to both groups. Both males and females born to the treated group had higher blood pressure than those born to the control mice. Body weight did not change in male mice born to treated mothers, but female offspring from the treated group were significantly heavier than those born to the control group. In a test which helps look for evidence of diabetes, females born to treated dams also showed increased blood sugar levels following a sugar challenge, but males were unaffected.

"This study highlights the importance of assessing both the short- and long-term consequences of therapeutics administered during pregnancy," the researchers wrote. Results from animal models of fetal growth restriction may lead to "a more informed choice for the obstetrician and patient on the potential short- and long-term risk vs. benefits of treatments in utero."
