Early-life Education Improves Memory in Old Age Especially for Women – Newswise

Newswise WASHINGTON Education appears to protect older adults, especially women, against memory loss, according to a study by investigators at Georgetown University Medical Center, published in the journal Aging, Neuropsychology, and Cognition.

The results suggest that childrenespecially girlswho attend school for longer will have better memory abilities in old age. This may have implications for memory loss in Alzheimers disease and other dementias.

The study tested declarative memory in 704 older adults (58-98 years of age). Declarative memory refers to our ability to remember events, facts, and words, such as where you put your keys or the name of that new neighbor.

Participants were shown drawings of objects, and then were tested several minutes later on their memory of these objects. The investigators found that their memory performance became progressively worse with aging. However, more years of early-life education countered these losses, especially in women.

In men, the memory gains associated with each year of education were two times larger than the losses experienced during each year of aging. However, in women, the gains were five times larger.

For example, the declarative memory abilities of an 80-year-old woman with a bachelors degree would be as good as those of a 60-year-old woman with a high school education. So, four extra years of education make up for the memory losses from 20 years of aging.

Simply said, learning begets learning says the studys senior investigator, Michael Ullman, PhD, a professor in Georgetowns Department of Neuroscience and Director of the Brain and Language Lab. Ullmans research on the relationship between language, memory and the brain has been a cornerstone in the fields of language and cognitive neuroscience.

Since learning new information in declarative memory is easier if it is related to knowledge we already have, more knowledge from more education should result in better memory abilities, even years later, adds the studys lead author, Jana Reifegerste, PhD, a member of the scientific staff at the University of Potsdam, Germany, who worked on this study as a postdoctoral researcher in Ullmans lab.

Evidence suggests that girls often have better declarative memory than boys, so education may lead to greater knowledge gains in girls, says Ullman. Education may thus particularly benefit memory abilities in women, even years later in old age.

The study tested individuals in a non-Western (Taiwanese) population. Participants varied in the number of years of education, from none at all to graduate studies. Future research is needed to test whether the findings generalize to other populations, Ullman says.

These findings may be important, especially considering the rapidly aging population globally, Reifegerste says. The results argue for further efforts to increase access to education.

Education has also been found to delay the onset of Alzheimers disease, Ullman says. We believe that our findings may shed light on why this occurs.

New Company to Advance Research into Made-in-Canada Therapy for Patients with Chronic Pain – BioSpace

MONTREAL, June 4, 2020 /CNW/ -adMare BioInnovations, Canada's Global Life Sciences Venture, along with partners McGill University and AmorChem II Fund l.p., a leading early-stage venture capital fund, is advancing made-in-Canada research that aims to provide new opiate-sparing pain-relieving drugs.

adMare and AmorChem have created a new company, Neurasic Therapeutics, based on breakthrough research from Dr. Philippe Sgula, professor of neuroscience at McGill University in Montreal, that was validated and further advanced by adMare BioInnovations. Dr. Sgula is a world-expert in ion channel biology and molecular pharmacology. His research lab at the Montreal Neurological Institute (the Neuro) is renowned for investigating genes, cells and circuits involved in pain perception and analgesia.

Neurasic's potential drug therapy targets acid-sensing ion channels (ASICs), a gene family of neuronal receptors activated by protons that play a role in multiple neurological disorders. Early research has shown that blocking ASICs elicits analgesia (the inability to feel pain) in chronic pain conditions, therefore eliminating the need for opiate-based drugs. Dr. Sgula and adMare have developed a proprietary method to identify molecules that block the ASICs.

"This drug development program is an excellent example of academic research that has the potential to provide the best-in-class treatments that patients need. adMare is proud to have been able to validate and advance this work, generate valuable IP and data, and bring together McGill and AmorChem to create a very commercially-attractive opportunity," says Gordon C. McCauley, President and CEO of adMare BioInnovations. "We are excited to maximize the potential of Dr. Sgula's discoveries on ASICs, along with the return on public investment in research."

"We have been following Dr. Sgula's work for a few years and see much promise in his research. The validation provided by the collaboration with adMare was an important factor in our decision to invest in this platform. We believe that Neurasic will benefit greatly from our three groups' combined expertise in early-stage investing and preclinical development in this field," added Maxime Ranger, General Partner at AmorChem and President of Neurasic.

"Early stage investing requires important financial resources and sustained collaborative work. It is therefore crucial to foster ties between Canadian stakeholders, and AmorChem is happy to partner with adMare and Dr. Sgula in building a Canadian anchor company in the pain space. AmorChem is particularly pleased to be providing Neurasic with Maxime Ranger's solid start-up management experience," says Ins Holzbaur, Managing Partner at AmorChem.

Dr. Guy Rouleau, CEO, Montreal Neurological Institute and Hospital (The Neuro)added, "Dr. Sgula and I are thrilled with the launch of Neurasic Therapeutics. This drug development program paves the way towards innovative strategiesto reverse the opioid crisis impacting Canadians countrywide.The creation of Neurasic also spearheads our vision that the Neuro could leverage its position as an open science institute to build attractive business models for its high-value technologies. Neurasic was enabled by NeuroSphere, McGill's neuroscience accelerator funded through HBHL, which was instrumental in driving this new endeavour and securing key partnerships to make this vision a reality."

"Healthy Brains, Healthy Lives (HBHL) is very proud to be part of Dr. Sgula's efforts to find safer alternatives to opioids through Neurasic Therapeutics," said Krystle van Hoof, Managing Director and CEO, HBHL. "We're dedicated to fueling neuroscience discoveries and innovations at McGill, and NeuroSphere, our neuroscience accelerator, allows HBHL to proactively ensure that critical medical breakthroughs reach patients. We will continue to proudly support Dr.Sgulaand Neurasic in their efforts, and will build on this first success to help advance other ground-breaking innovations in the near future."

How to make good decisions when you’re paralyzed by the stress of protests and the pandemic – WMTW Portland

Do you find it tough to make decisions these days? What used to be no-brainers, stopping at the grocery for bread and milk, making a pit stop at the gas station or meeting friends for dinner and drinks are now fraught with dangers.Are people wearing masks at the grocery and keeping their carts at a proper distance of 6 feet? Did you bring gloves or hand sanitizer for the gas pump? Will the restaurant have outdoor socially distant seating and just how does one eat with a mask?And now we're fighting back tears and struggling with rage over the killing of George Floyd, the unarmed and handcuffed black man in Minneapolis who died after gasping "I can't breathe" as a white police officer pressed a knee into his neck."It's crazy times, with protests and a pandemic and things at every level appearing untrustworthy," said biochemist Bita Moghaddam, who chairs the behavioral neuroscience department in the school of medicine at Oregon Health and Science University.Moghaddam, who studies how anxiety affects the brain, said it's no wonder our stressed, overworked brains can't spit out a decision. We have become victims of "analysis paralysis.""We don't know exactly what's going to happen tomorrow, next week, next month," Daphna Shohamy, who is a professor of psychology at Columbia University, told CNN Chief Medical Correspondent Dr. Sanjay Gupta in a recent podcast.And we're all forced to make decisions in that state of uncertainty and to just rely on what we do know, which is not good enough," said Shohamy, who studies the cognitive neuroscience of learning, memory and decision-making."I notice it myself all the time," Gupta said in the podcast. "As simple as choosing a tie in the morning, what I'm going to have for lunch, whether I'm going to go for a run or a bike ride."Those were decisions that usually took me just a few seconds, and now sometimes I just find myself struggling," he said.How the brain makes decisionsThe headquarters for our decision-making capabilities is the prefrontal cortex, which controls our higher-level executive functions. Those include focusing our attention, creating and organizing thoughts, setting goals, planning actions and putting a stop to impulsive thoughts and behaviors.Under normal or mild stress conditions, the brain uses "working memory" to regulate our mood and actions from the top down. Working memory marries recent events with memories from long-term storage about what we learned from any experience, and it uses this to make decisions about how we should act, think and feel based on our experiences. And, of course, it helps us anticipate and predict possible consequences from our actions."The brain is constantly estimating risk," Moghaddam said."I'm hungry. I'm going to get up and drive to a pizzeria to grab some pizza. But driving involves risk because you could get into an accident," she said. "If you're suffering from anxiety disorders, you may say, 'No, I'm not going to even risk getting in the car because I couldn't relax.' If you're drunk, then the risk is even higher. And it becomes a computation game."It takes the first quarter of life for the decision-making area of the brain to fully mature in humans.

Even mild stress can cause "rapid and dramatic loss of prefrontal cognitive abilities," while prolonged stress can actually change the brain, according to Amy Arnsten, a professor of neuroscience and psychology at Yale School of Medicine.When we are stressed all the time, certain neurotransmitters go awry, flooding the brain with chemicals that change the structure and functioning of the prefrontal cortex and the fight-or-flight emotion and memory centers of the brain. Working memory suffers, and our ability to make quick or well-thought-out decisions declines."In general, decision-making slows down," Moghaddam said. "You could argue it's better for our survival.

"Most of us didn't think of going to a grocery store as a dangerous thing before, yet now it has become an anxiety-provoking process."What to do next?Give your brain a break from its constant risk calculations.Try to take 10 to 15 minutes to close your eyes and meditate, pushing all of your worries and decisions to the side during that time.You can see physical changes in the brain in a short time, said psychology and psychiatry professor Richard Davidson, founder and director of the Center for Healthy Minds at the University of Wisconsin - Madison.Davidson did a randomized controlled trial of people who've never meditated before.

Growth factors and Parkinson’s disease — Where next? – Science Codex

Amsterdam, NL, June 4, 2020 - Growth factors such as glial cell line-derived neurotrophic factor (GDNF) were initially thought to be exciting new treatments for Parkinson's disease (PD), but trials have been disappointing. A panel of prominent leaders in the field convened to discuss whether there is a future for this approach and what any future PD trial involving GDNF and other GDNF family neurotrophic factors should consider. Their discussions and recommendations are published in the Journal of Parkinson's Disease.

"There is clear evidence that GDNF and related growth factors can restore the dopaminergic nigrostriatal pathway in several animal models of PD," explained lead author Roger A. Barker, PhD, Cambridge Centre for Brain Repair, Department of Clinical Neuroscience and WT-MRC Cambridge Stem Cell Institute, Cambridge, UK. "However, this has yet to translate into a clinically meaningful and robust response in patients."

Growth factors support the development, growth, and survival of cells in the body and brain. The concept of repairing the brain with growth factors has been pursued for many years in a variety of neurodegenerative diseases including primarily PD. Their properties make them an exciting prospect for developing new treatments that could help repair the damage caused in PD.

An international group of experts met to discuss the history and current status of GDNF and related growth factor neurturin (NRTN) therapy for PD, comprehensively reviewing preclinical and clinical studies. Critical evaluation led to conclusions about what has been achieved and what has not been shown using these agents. It was generally agreed that GDNF and NRTN have worked relatively well in neurotoxic animal models of PD, but that their translation to the clinic has so far failed to show a major impact, perhaps highlighting the predictive limitations of toxin animal models being commonly used in the preclinical space in PD to look at disease modifying therapies.

"As to what any trial should look like, there is still much debate as to what primary end-point should be used and at what time point, and input from the patient community on this will be vital going forward," noted co-author Anders Bjorklund, MD, PhD, Wallenberg Neuroscience Center, Lund University, Lund, Sweden.

The workshop participants agreed that the question of whether GDNF has a competitive future in the treatment of PD is still unclear. They offered recommendations about what future trials with GDNF should consider and how they might be designed. For example, compared to the relative complexity of the neurosurgery needed to implant an infusion delivery system and ongoing infusions used in a recent GDNF trial, they felt a viral delivery system using newer modified approaches requiring less complex surgery would be more advantageous. In addition, they indicated that early stage PD patients would most likely benefit from such treatment because this group would have the most neurons and fibers left to rescue, with evidence of fiber loss restricted to the dorsal striatum, where the therapeutic agent could be targeted.

The workshop concluded that future trials with GDNF and related agents should be considered but that much more careful attention is needed to be given to all aspects, including the type of patient enrolled; the form of growth factor given; the dose and volume of agent given; the mode of delivery and length of follow-up along with optimal assessment tools.

Chemical messenger in brain could point to better treatments for anxiety – Folio – University of Alberta

New research by a University of Alberta neuroscientist reveals more about how the mechanism the brain uses to regulate our response to stress could lead to better treatments for anxiety.

Bill Colmers and his team discovered that two chemical messengerscorticotropin-releasing factor (CRF) and neuropeptide Y (NPY)work in a synchronized opposition to one another to remodel and rewire neurons in a part of the brain responsible for emotions, called the amygdala, as part of the bodys natural response to stress.

The research not only shows the change is occurring in the amygdala, but also reveals the process can be manually reversed, said Colmers.

Anxiety disorders represent a huge unmet medical need. Any new information we can gather in relation to understanding the mechanisms involved with anxiety provides new targets for possible drug development, said the U of A professor of pharmacology.

The amygdala is a small, almond-shaped structure in the brain where information from our senses is combined with our memories and experiences.

When you see a car, its just a carunless you were previously T-boned by a red convertible. Then, thanks to your amygdala, that red convertible will elicit negative feelings in you, explained Colmers.

We see abnormal functioning in the amygdala in individuals who suffer from conditions such as anxiety, depression and post-traumatic stress disorder. Its an interesting part of the brain thats responsible for many essential processes, and its where we see the NPY and CRF in action.

In previous research, Colmers team showed that NPY reduced anxiety in rats. Repeated exposure to NPY made the animals more resilient to stress for weeks or even months, and the team was able to identify the exact mechanism that elicits this response.

Building on this research, Colmers team observed that the bodys ability to react to a stress or threat is the result of CRF increasing the number and length of dendrites (or branches) found in neurons located in the amygdala. The lengthening and expansion of the neural network allows the brain to increase its signalling power and trigger the rest of the body to get ready to respond.

But the longer and more often our brains are in hyperdrive, which makes us feel anxious, the more difficult it is to get back to a healthy state.

Because its harmful for our bodies to be in this amped-up state for too long, NPY is normally released in our brains once the perceived threat has passed.

The NPY has the opposite effect of CRF and reduces or shrinks the number and length of the dendrites, effectively telling the brain to stand down from the alert and let the body relax.

Colmers research also revealed that one of the first steps in getting back to this relaxed state begins when NPY binds with the Y5 receptor, which occurs on the surface of a neuron. This binding activates the pathway that reconfigures the dendrites. According to Colmers, understanding each step in the pathway is important because each represents a potential target for drug development.

My research areas have varied throughout my career and included anxiety, obesity, cachexia and energy balance. However, the common thread that has run through all of it is my friend neuropeptide Y, said Colmers.

While we definitely answered some of our questions with this latest study, it also revealed new questions, as the work was only conducted in male rats. The very important next question is whether this works the same in females.

Colmers, a member of the Neuroscience and Mental Health Institute, and his collaborator Janice Urban from the Rosalind Franklin University of Medicine and Science, published the study, Contribution of NPY Y5 Receptors to the Reversible Structural Remodeling of Basolateral Amygdala Dendrites in Male Rats Associated With NPY-Mediated Stress Resilience, in The Journal of Neuroscience.

The research was funded by the U.S. National Institutes of Health and the University Hospital Foundation. Trainees were funded by Alberta Innovates and the Canadian Institutes of Health Research. Colmers was a medical scientist with the Alberta Heritage Foundation for Medical Research at the time.

Kali Ladd’s Powerful Words on the Protests in Portland – Portland Monthly

Editors Note: On Sunday, May 31, Kali Ladd, Executive Director of Kairos Pdx, spoke at SEI along with other community leaders about the ongoing protests in Portland over the killing of George Floyd. With permission, we're running thistranscript of her speech to the city.

Good afternoon,

As I thought about my remarks this morning, all I could see was my children. My 8-year-old son and 11-year-old daughter. The wondering of what does all of this look like through their eyes? I see their beauty and innocence, their intellect and brilliance, and wonder how the world will snatch it away from them. And then my head begins to spin.

You see, because Ive devoted my life and career to children, I am always palpably aware of their presence. I know they are watching what we do, and what we dont do. Watching what we say, and what we dont say. Every moment is instructive. They are listening for something, and if they only hear silence their heads are filled with noise. And this noise can be fear, this noise can be depression, this noise can be complacency, the noise can be grief.

And while I dont condone the looting and vandalism, I know that it is a symptom, not the problem. I know it personifies how I feel inside and I wonder if its not an opportunity to help my children see this too. That as wrong as it may be, it is a symbol of our shattering, our devastation, and our internal beating every time we see a life lost like George Floyd.

George Floyd called out to his mother. His cry reaches the heart of all of us moms. We see our sons and our daughters and we are in shambles.

But I think there is hope. I think there is hope because I come from a people who carry hope across generations. A people who despite devastation and terrorization and oppression have written spirituals that lift this whole nation up in hope. A people that have strengthened the fiber of our being even when forces are taking away our breath.

I also think there is hope because I study neuroscience and psychology and child development and these things tell us we can create a new narrative. But as mothers and fathers and educators we need to be intentional. This does not happen by chance.

Our brains are incredible, miraculous things that can be wired and rewired by our words and our actions. They call it neuroplasticity.

The science tells us that children are not born hating other children or rendering certain people invisible. This happens over time. You see every circumstance is a data point that forms an idea. Watching that black boy in pre-school get kicked out of class repeatedly is a data point, pretending as though the founding of this country did not come at the hands of genocide is a data point, silence in the aftermath of a killing is a data point.

And these data points form ideas. And these ideas begin to cluster and form schema. And this schema dictates behavior.

We are developing racist schema and reinforcing racist ideas in the minds of our children when we fail to talk to them about racism. When we fail to tell the truth about history. When we fail to point out injustice whether its overt or covert.

You see, when we put children at the center of our lives, our comfort or discomfort become less and less important. Our words today can save lives tomorrow. Our children are the souls we will send into a time we will likely never see.

Because when were stressed, whats inside of us, come out. When Amy verbally attacked Mr. Cooper watching birds in central park, what was inside of her came out. Let this be a warning to us all.

But what was inside of Mr. Cooper also came out. Let him be an example of what happens when we build in our children the moral character of calm, grace and forgiveness even amidst our lives being threatened.

The neuroscience and social science tell us that diversity matters. As human beings we dehumanize what we dont know; we fear what we dont understand. Our brains will rely on data derived by soundbites and stereotypes instead of facts when we don't have real people of different races and backgrounds in our lives.

Toya Fick wrote an op-ed in yesterdays Oregonianabout the importance of retaining teachers of color. So well timed. because this is something we can do now. This is a way to actively combat racialized violence. When we do this, we make our schools safer for our black and brown children. We break down fear for our white children. And collectively our children get one step closer to seeing the humanity of another.

This is everything because I believe that when a white child can see the humanity of my black son, it becomes that much harder to crush him with their knees. Diversity is not just anti-racist, its humane.

The list can go and on, but I will stop here. Let there be no question that there is something we can do right here and right now to change the course of history. It lies with our children. It lies with the roadmap we are building in their brains. It lies in the ways that we wire and reinforce their wiring.

We are giving them the data that informs their schema with the words we use or dont; the care we give or withhold and the people they see or dont. Every. Sing. Day. I cant think of any greater light in the darkness than them.

Lets collectively illuminate these lights, strengthen them to understand the tenuous tentacles of racism so they can dismantle them. Let us collectively seek to build strong and resilient children rather than repair broken adults. Love them, love them, love themespecially our black boysso they are resilient and strong in the face oppression. Do not dismiss them or their pain and dont exacerbate it. Talk up and not down to them. Collectively lets do what it takes to build in our children, a foundation that can effectively disrupt the patterns of injustice and destroy the stronghold of hatred that brings us all here today. Children are not just our future, I really do believe. they are our greatest hope.

Highlighting Cancer Prevention, Risk Reduction, and Genetics in Cancer Treatment – Pharmacy Times

The key components for cancer risk, genetics, and prevention include application of results, indications for germline testing, and testing updates, according to a session presented at the 2020 American Society of Clinical Oncology (ASCO) Virtual Scientific Program.

Providing quality of care in a field of cancer risk, genetics, and prevention revolves around 3 essential interdependent components, said presenter Erin Wysong Hofstatter, MD.

Germline TestingIn the study, the researchers wanted to assess the clinical utility of identifying germline alterations in cancer susceptibility genes for targeted therapeutic interventions in a pan-cancer patient population.

By using a subset of pan-cancer MSK-IMPACT patients who consented to additional germline testing, 88 genes were analyzed in addition to a medical record review of pathogenic/likely pathogenic (P/LP) patients to assess use of targeted treatment. Out of 11,974 patients between 2015 and 2019, 7.1% harbored a P/LP alteration in a targetable gene. Meanwhile, 44.4% of patients received targeted therapy based on germline results. Overall, 58.1% of Lynch patients received therapy irrespective of microsatellite instability status.

Our study represents the first comprehensive assessment of the clinical utility of germline variants for targeted therapeutic interventions in advanced cancer patients, Hofstatter said.

When it comes to the emerging indication for germline testing, this is equivalent to selecting cancer treatment in the advanced setting, she noted.

Know your test, Hofstatter said. Tumor sequencing is not a substitute for comprehensive germline testing.

Testing UptakeIn testing uptake, germline genetic testing among patients, both affected and unaffected, remains poor, according to Hofstatter. Only 30% of an estimated 35,0000 BRCA-positive cancer patients have been diagnosed with a genetic mutation, and up to 98% of Lynch carriers have yet to be identified, Hofstatter said.

Barriers in genetic testing uptake for the patient and provider include lack of knowledge, cost, and fear of discrimination. The next 2 abstracts detailed by Hofstatter were done to evaluate the completion of video-education (VE) or in-person pretest genetic counseling (GC) over time by a randomization arm and to test whether pre and/or post-test GC is needed to optimally deliver online accessible genetic testing.

The first abstract found that there was a high uptake of intervention in both GC and VE and a high completion of genetic testing with no difference by arm. Meanwhile, the second abstract found that the completion rate was highest in the 2 arms with no pre-test counseling, with support of the use of a genetic testing paradigm providing individualized post-test genetic counseling only for patients with positive results and for those patients who request additional counseling.

Application of ResultsMost genetic testing for cancer susceptibility is done using multigene panels, according to Hofstatter. The identification of pathogenic variants (PV) with a risk of ovarian cancer is > 5%.

Variants of uncertain significance should not be used to alter medical management recommendations, and PV in other genes are not associated with a risk of OC >5%, Hofstatter said.

The aim of the last abstract was to help describe the use of preventive, or risk-reducing, salpingo-oophorectomy (RRSO) among individuals with different test results and how use varies across personal and family history. The study found that the majority of patients reported that RRSO was either recommended or discussed as an option by their provider. Additionally, further data are needed on communication between patients and providers regarding the implications of genetic information and management options.

Hofstatter concluded that the 3 key components to provide quality care in the field each are important for patients with cancer and are actionable points to make. For example, in terms of germline genetics, understanding the germline component of tumor testing of choice can truly affect cancer treatment.

For pre-test video counseling, this type of testing is feasible and acceptable to patients, with the help of a local GC team.

Ask yourself: how might this enhance testing uptake in your practice? Hofstatter said.

Lastly, Hofstatter emphasized that individual management must be based on accurate risk assessment.

There is a responsibility of the provider to understand the implications of testing results, whether positive or not, Hofstatter said. Stay updated by reviewing NCCN guidelines, ASCO guidelines, and watching the ASCO Annual meeting.

The Genetics of Cancer – Technology Networks

InfographicJun 02, 2020| By Molly Campbell and Laura Elizabeth Lansdowne, Science Writers, Technology Networks.

Cancer is the term used to describe an incredibly complex group of diseases, caused by changes to the genes in one cell or a group of cells. These genetic alternations disrupt the normal functioning of the cell/s giving rise to several phenotypic changes or hallmarks that distinguish them from healthy cells in the body.
