Novel hybrid device to boost research on metastatic process of breast cancer cells – News-Medical.Net

European researchers are working on a novel hybrid device to better understand the metastatic process of cancer cells traveling from breast to bone and fast screen new drugs against it.

The spread of cancer cells to other parts of the body, known as metastasis, is the main cause of cancer-related deaths. According to the US National Cancer Institute, in 2018 there were 9.5 million deaths caused by cancer worldwide, and a high percentage of those involved tumors that had spread across the body.

However the metastatic process remains one of the most enigmatic aspects of the disease. To understand it, we have to take a step back and look at the biology of the primary tumor.

Roger Gomis, head of the group growth control and cancer metastasis at the Institute for Research in Biomedicine, in Barcelona, explains: "Essentially what you have in a tumor is an original cell or a small group of cells that receive oncogenic signals, such as tobacco or UV light. Those inputs induce alterations known as mutations, which make the cells start proliferating in a dysregulated manner. The tumor mass starts growing and expanding and, in order not to run out of supplies and collapse, some cancer cells spread to other organs. Cancer cells spread not because they are encoded to the metastasis but just because it's crowded."

What we observe in cancer is an accelerated process of evolutionary species, trying to leave one site to grow on foreign soil. The site where tumor cells metastasize is not random, it rather follows a specific tissue pattern based on the Darwinian theory of evolution.

Gomis uses the Galapagos Islands as an example to explain. "You have a population of birds that have flown from Ecuador. They reach the islands and they adapt to the conditions of each island, forming new bird species. Why did birds colonize the Galapagos Islands and not dogs or reptiles? Because they could fly! So the genetics made them the candidates. But then, there is a process of adaptation that is imposed by the characteristics of the destination; for example the latitudes and where the food is," he says.

In terms of metastasis, it is the same. The fact that metastatic cells metastasize on a particular site depends on the genetics of the cells, the characteristics of the metastatic tissue and the ability of the tumour cells to adapt to and grow in the new environment. A great example of this is breast cancer.

The bones are the most common place where metastatic breast cancer cells tend to go. Although the research on tumors has exponentially grown in the past years, the major hurdle to decreasing mortality is to find out where the cancer cells will spread. To understand the process, scientists need relevant cancer models, which are lacking.

The main reason why it has been so difficult to translate the findings into the clinical settings is that the models of the laboratory sometimes do not factor in everything we have in the clinics. The laboratory mice, in terms of metastasis, do not always recapitulate what we see in the patients. For example, the breast cancer that we generate in the mouse tends to metastasize to the lung but it's rare to see it in the bones."

Roger Gomis, Institute for Research in Biomedicine, Barcelona

Providing better models to shed light on the bone metastatic process is the aim of the B2B project, supported by the EU Future and Emerging Technologies (FET) programme. Its interdisciplinary consortium are creating a cutting-edge device that mimics the spontaneous metastasis process from the breast to the bone.

Their innovative technology includes a patient-derived breast cancer lesion connected to a reconstructed bone via a complex vascular network. "The fluidic system mimics the features of human blood vessels feeding and connecting living tumour cells from breast cancer to the target metastatic tissue, which is the bone," explains Silvia Scaglione, group leader of the CNR-IEIIT Bioengineering laboratory of Genoa, and coordinator of the project.

The level of physiological complexity of the project is really high but this is necessary if we are to capture all the key elements of the metastatic process. "Usually cancer is studied either using in vitro static models or in vivo animal models. However, both approaches fail to recapitulate the metastatic process for different reasons. The static model can't mimic the fluidic connections between the breast cancer and the metastatic side, while the animal model doesn't resemble the spontaneous breast metastatic onset," she says.

If successful, the B2B device will be an in vitro alternative that features three new complementary technologies. The first is clinically relevant-sized organoids that are able to resemble what is happening in vivo. "If you miniaturize too much the cancer tissue, as in some other in vitro approaches, you lose some biochemical and molecular features such a hypoxic core within the tumor tissue," Scaglione explains.

The second is the generation of the ossicle, the bone tissue containing the target of metastasis, in vitro. "We started using mice models to make the ossicle, since it is impossible with our knowledge in the world to create the bone marrow, which is the target of the metastatic cancer cells. In parallel, the partner involved in this task is working on a novel in vitro approach using patient-derived stem cells to create bone tissue and thus by passing completely the animal step," says Scaglione.

The third is the fluidic system that connects the breast and bone tissues, which is entirely based on human physiology. The system consists of a micro-vascular capillary network, which is formed spontaneously around the tumour tissue, connected to a functional bioprinted macro-vascular tree.

Scaglione sees a future whereby any crosstalk between organs can be studied using the B2B platform, reducing the need for animal models and supporting scientists in advancing knowledge on tumors. "We have selected the breast metastasis as a case study but, of course, our platform will be adapted for many other diseases," she says, "Not necessary for cancer, but, for instance, fibrosis or other cases where you have an interaction between different tissues that are vascularised and fluidically connected. Also, the platform will be useful for studying the pharmacokinetics of any type of drugs."

Scaglione also believes that this technology will accelerate the identification of metastasis-suppressing therapies for breast cancer patients and will help pre-screen novel personalized cancer therapies, which will ultimately have a high impact for oncological patients.

Ga. Parents Of Transgender Athletes React To New ‘Female-Only Sports’ Bill | 90.1 FM WABE – WABE 90.1 FM

Georgia LGBTQ advocacy groups are criticizing new legislation that they say discriminates against transgender youth.

Republican state Rep. Philip Singleton announced House Bill 276 on Thursday, along with 36 other House members who have already co-signed the legislation.

Singleton announced the bill would stop state public schools and universities from allowing biological males to participate in girl-only sports. If passed, HB 276 would also allow students to sue schools that deprive them of athletic opportunities, as a result of violating the law.

No one here is concerned with how any person chooses to identify their gender, Singleton said during a press conference in the Georgia Capitol building, alongside his family and other young, female athletes lined up behind him.

We believe every single athlete should have the opportunity to compete, and there is no place for identity politics, or discrimination of any type, in sports.

Singleton then introduced his 10-year-old daughter Emma and put her in front of the mic, saying the bill is about biology and physiology, not psychology or sociology.

I dont think it is fair for girls who are playing in girls-only sports to have to play against boys, she said.

The boys are naturally born stronger and can usually beat girls.

But one former Georgia politician is joining in with critics of the bill who say its a discriminatory, shameful attack on Georgias transgender youth and young adults.

Jen Slipakoff ran to represent Georgias State House District 36 in 2018. She said her daughter a young, transgender athlete in a conservative Georgia district would be devastated if the bill passes.

I havent told her. I havent told her because I dont know what to tell her, Slipakoff said in response to a question about her daughters reaction to HB 276.

What do you say to that? Theres some lawmaker who has never met a transgender person, probably, who thinks that you should not play? Who has never met you, and thinks you shouldnt play lacrosse with your friends? What a heartbreaking conversation.

The bill would force state universities to disregard NCAA guidance on transgender athlete inclusion.

Kevin Kregel named permanent provost and executive vice president at University of Iowa – UI The Daily Iowan

Pending Board of Regents approval, current interim provost Kevin Kregel will fill the role permanently beginning Feb. 15.

The University of Iowa removed another interim title this week.

Kevin Kregel, the UIs interim provost and executive vice president, was named a permanent provost and executive vice president on Thursday. Kregel, has served in the interim since July 2020, when former provost Montse Fuentes stepped down from the position for a role as special assistant to the president. Kregel will start Feb. 15 with an annual salary of $439,000.

Its the second role the UI has upgraded to permanent since the start of the semester two weeks ago. The UI named Liz Tovar as the executive officer of diversity, equity, and inclusion after serving in the interim role since August.

Kregel graduated from the UI with a bachelors degree in biology and a doctorate in physiology and biophysics. In 1993, he joined the UI faculty and has since served as department executive officer in the Department of Health and Human Physiology before being appointed associate provost in September 2014 and to the executive vice provost and senior associate provost for faculty role in July 2019. Hes also participated in steering committees for two cluster-hire initiatives and in the role of acting associate provost for undergraduate education and dean of University College in 2018.

While serving as interim executive vice president and provost, Kevin has demonstrated strong leadership and collaboration that has helped carry the university through the challenging pandemic, said UI President Bruce Harreld, according to a UI media release. His long career at Iowa has provided him with unmatched knowledge and insight that position the university for continued excellence.

UI spokesperson Anne Bassett pointed the DI to Harrelds quote in the news release in an email asking for details on why the UI decided to appoint two current interims without searches in the last few weeks. The UI has used searches in the past to fill open administrative positions, including one in fall 2020 that led to the appointment of Amy Kristof-Brown as Tippie College of Business dean after serving as the interim since March.

The previous provost, Fuentes, was reassigned to a new position created within the presidents office in July, maintaining her $439,000 provosts salary. Per the universitys contract, she would hold that position until June 30, 2021.

Fuentes will take the helm of St. Edwards University, a private Catholic liberal arts university in Austin, Texas on July 1, 2021 as its president.

I am honored to serve as provost at Iowa, which has been such a meaningful part of my life since I was an undergraduate student, Kregel said, according to a UI press release. I look forward to building upon the relationships I have established during my time as interim and continuing to deliver an excellent educational experience to our students and improving the workplace experience for our faculty.

As climate change cranks up the heat in the Mojave Desert, not all species are equally affected – Iowa State University News Service

AMES, Iowa Climate change doesnt affect every species equally.

Even among species that share the same habitat, some organisms adapt more readily than others to environmental fluctuations wrought by climate change. This realization has led biologists to try to predict which species are most vulnerable to climate change.

A new study published this week in the peer-reviewed journal Science shows how climate change is having a much greater impact on birds than small mammals in the Mojave Desert in the southwestern United States. The study, led by an Iowa State University scientist, utilized computer simulations to explore differences in how birds and mammals experience the direct effects of climate warming on their ability to maintain a stable body temperature.

The study could inform conservation practices and shed new light on how animals respond to changes in their environment, said Eric Riddell, lead author of the study and an assistant professor of ecology, evolution and organismal biology.

We wanted to answer how physiology influences where animals can live and their vulnerability to climate change, Riddell said. We built these simulations that mimic how animals interact with their environment so we can identify which combinations of traits make species vulnerable to climate change and which ones dont.

Riddell contributed to the project as a postdoctoral researcher at the University of California, Berkeley. A UC Berkeley biologist named Joseph Grinnell collected copious amounts of data on wildlife in the Mojave region in the early 1900s. Biologists conducted surveys in recent years at the same sites visited by Grinnell, comparing todays wildlife populations to those of 100 years ago. The new study drew on data for 34 small mammal species at 90 sites and 135 bird species at 61 sites located primarily on protected lands in southeastern California. Previous analyses showed that, as the Mojave Desert grew hotter and drier as a result of climate change, bird populations collapsed while mammals held steady.

Steven Beissinger, a UC Berkeley professor of environmental science, policy and management and a researcher at the Museum of Vertebrate Zoology, said the extreme environment of the desert highlights the biological differences noted in the study.

Scientists tend to assume that most species in a region experience the same exposure to temperature or precipitation changes, and that they all respond in the same way, Beissinger said. But, we're finding now that animals have diverse strategies for reducing their exposure to hot and dry conditions that could kill them. You should see these differences most strongly in a harsh environment like the desert, where life is really on the edge.

Computer simulations conducted by Riddell for the study explain those changes by examining the biology and behaviors of the species in question. Riddell compared the way animals control their body temperature, similar to how houses control temperature. We devote energy to warm our houses in the winter or cool our homes in the hot summer months, all to maintain a comfortable temperature range. Similarly, animals must devote energy to regulating their temperature as well, Riddell said. The amount of energy animals have to devote to cooling themselves in hot conditions is called the animals cooling cost. Riddells computer simulations showed how birds in the Mojave region, such as the prairie falcon and the mountain chickadee, have higher cooling costs than the small mammals that live in the same region. The small mammals analyzed in the study include rodents such as the cactus mouse or the kangaroo rat.

Riddells models account for how the animals bodies absorb or reflect sunlight, how insulated their bodies are and a range of other factors. The differences in cooling costs observed in the study accounts for the discrepancy in bird and mammal populations. Hotter conditions have a greater impact on birds because their cooling costs are higher, according to the study.

Riddell said studies like his can guide conservation policies. He said the study shows that basing climate change responses solely on the degree of warming in a region is unlikely to benefit all species in an area.

Rather, we may need to focus on predicting the unique experience of climate change for species to identify regions with the greatest potential to harbor the most species under climate change, Riddell said.

And monitoring species within affected areas might help scientists gauge the pace of climate change and how quickly mitigation strategies should be enacted, he said.

The soundscape of the Anthropocene ocean – Science Magazine

An anthropogenic cacophony

Sound travels faster and farther in water than in air. Over evolutionary time, many marine organisms have come to rely on sound production, transmission, and reception for key aspects of their lives. These important behaviors are threatened by an increasing cacophony in the marine environment as human-produced sounds have become louder and more prevalent. Duarte et al. review the importance of biologically produced sounds and the ways in which anthropogenically produced sounds are affecting the marine soundscape.

Science, this issue p. eaba4658

Sound is the sensory cue that travels farthest through the ocean and is used by marine animals, ranging from invertebrates to great whales, to interpret and explore the marine environment and to interact within and among species. Ocean soundscapes are rapidly changing because of massive declines in the abundance of sound-producing animals, increases in anthropogenic noise, and altered contributions of geophysical sources, such as sea ice and storms, owing to climate change. As a result, the soundscape of the Anthropocene ocean is fundamentally different from that of preindustrial times, with anthropogenic noise negatively impacting marine life.

We find evidence that anthropogenic noise negatively affects marine animals. Strong evidence for such impacts is available for marine mammals, and some studies also find impacts for fishes and invertebrates, marine birds, and reptiles. Noise from vessels, active sonar, synthetic sounds (artificial tones and white noise), and acoustic deterrent devices are all found to affect marine animals, as are noise from energy and construction infrastructure and seismic surveys. Although there is clear evidence that noise compromises hearing ability and induces physiological and behavioral changes in marine animals, there is lower confidence that anthropogenic noise increases the mortality of marine animals and the settlement of their larvae.

Anthropogenic noise is a stressor for marine animals. Thus, we call for it to be included in assessments of cumulative pressures on marine ecosystems. Compared with other stressors that are persistent in the environment, such as carbon dioxide emitted to the atmosphere or persistent organic pollutants delivered to marine ecosystems, anthropogenic noise is typically a point-source pollutant, the effects of which decline swiftly once sources are removed. The evidence summarized here encourages national and international policies to become more ambitious in regulating and deploying existing technological solutions to mitigate marine noise and improve the human stewardship of ocean soundscapes to maintain a healthy ocean. We provide a range of solutions that may help, supported by appropriate managerial and policy frameworks that may help to mitigate impacts on marine animals derived from anthropogenic noise and perturbations of soundscapes.

The illustrations from top to bottom show ocean soundscapes from before the industrial revolution that were largely composed of sounds from geological (geophony) and biological sources (biophony), with minor contributions from human sources (anthrophony), to the present Anthropocene oceans, where anthropogenic noise and reduced biophony owing to the depleted abundance of marine animals and healthy habitats have led to impacts on marine animals. These impacts range from behavioral and physiological to, in extreme cases, death. As human activities in the ocean continue to increase, management options need be deployed to prevent these impacts from growing under a business-as-usual scenario and instead lead to well-managed soundscapes in a future, healthy ocean. AUV, autonomous underwater vehicle.

Oceans have become substantially noisier since the Industrial Revolution. Shipping, resource exploration, and infrastructure development have increased the anthrophony (sounds generated by human activities), whereas the biophony (sounds of biological origin) has been reduced by hunting, fishing, and habitat degradation. Climate change is affecting geophony (abiotic, natural sounds). Existing evidence shows that anthrophony affects marine animals at multiple levels, including their behavior, physiology, and, in extreme cases, survival. This should prompt management actions to deploy existing solutions to reduce noise levels in the ocean, thereby allowing marine animals to reestablish their use of ocean sound as a central ecological trait in a healthy ocean.

Campaign urges people not to ignore signs of a heart attack – In Your Area

Photo: The cardiac Physiology team at Glan Clwyd Hospital, Bodelwyddan

A health campaign is reminding people who suffer with worrying chest pain symptoms of the importance of seeking medical attending during the COVID-19 crisis.

Throughout 2020 and into the new year there have been hundreds of people experiencing palpitations, chest pains and other symptoms of heart failure and staying at home rather than calling 999 to receive urgent medical attention.

Claire Gallagher-Harrison, Head of Cardiac Physiology at Glan Clwyd Hospital, Bodelwyddan, Denbighshire, says the new strain of the virus has increased concerns after confidence was slowly rebuilding following the initial national lockdown.

Reinforcing the Betsi Cadwaladr University Health Board (BCUHB) and Welsh Government Help Us, Help You campaign, she assured the public it is safe to visit the department for vital treatment, including echocardiograms.

During the first wave of COVID-19 last Spring, even urgent patients would not attend the hospital as they were very frightened, it was unprecedented and unknown, said Claire.

We had to cancel all outpatient appointments but because we provide such a key role for wards across the hospital, we continued to provide urgent diagnostic tests.

Things had picked up again and the winter is usually by far our busiest time of year, but understandably there is uncertainty.

In fact, to not get checked out could cause damage beyond repair, so we need anyone who feels they are showing signs of heart problems or palpitations to seek help immediately.

In 1990, Glan Clwyd Hospital carried out around 500 echocardiogram ultrasound scans - known as an echo - every year.

Now, that annual figure is more than 8,500, and with people living longer and a rise in the number of heart attacks among adults under 50, Claire says it is vital the warning signs are not ignored.

Due to the challenges of COVID-19, the 23-strong Cardiac Physiology team is still working through the backlog of appointments but are committed to delivering the same level of service and care for patients.

Those words were echoed by Head of British Heart Foundation (BHF) Cymru Adam Fletcher, who said: If you think you're having a heart attack or stroke it's crucial that you call 999 immediately, as every minute counts and prompt treatment saves lives.

If your heart symptoms are getting worse, get in touch with your healthcare team so that they can reassess your situation. Delaying risks your life and you are more likely to suffer serious heart damage and spend longer in hospital, so don't hesitate in seeking medical help.

Developing a Weight Training Program for Greater Strength and Power – The Great Courses Daily News

ByMichael Ormsbee, PhD,Florida State UniversityEdited by Kate Findley and proofread byAngelaShoemaker, The Great Courses DailyAt the start of a weight training program, it is important to learn proper alignment and form, then develop a specific plan tailored to help you meet your individual goals. Photo By Jiri Hera / ShutterstockGetting Started

When developing a weight training program, you can refer to the American College of Sports Medicine (ACSM) guidelines, which take into account the recommendations of experts across many disciplines, like exercise science, physiology, athletic training, and medicine. ACSM recommends lifting weights a minimum of two to three days per week if you use a fullbody workout.

However, if you really enjoy strength training, you can easily spread it out over four or more days per week and change up the order of the muscle groups you exercise each time. Training each major muscle group twice per week is sufficient.

To begin, ask yourself, what fits into your schedule now? If it is only one day per week, start there. Over time, you can add more days, time, and intensity to your training.

Professor Ormsbee recommends starting with one to three sets of exercises that target each major muscle group. Aim for 8 to 12 repetitions.

Often, beginning with machines instead of using free weights is your best bet because they help to reinforce proper alignment and form and may be safer until you feel more comfortable with the process. As you become more advanced with your program, and your goals become more specific, you can develop a specific plan tailored to help you meet those goals.

When designing a plan to build muscle mass or improve muscle quality, a few criteria are unique. Muscular strength is a measure of how much force your muscles can produce in one effort.

To improve strength, do five to eight repetitions at a weight that progresses up to 80% of your maximal strength for one repetition, or RM. Think higher weight and low to moderate reps for three sets.

For example, if you can lift 100 lb, or 46 kg, on the bench press, then you would start with about 6570 lb, or 2931 kg, and work up to using around 80 lb, or 36 kg, for five to eight repetitions. You would repeat this two more times before switching exercises.

The second type of muscular training is muscular endurance, which ultimately leads to hypertrophy, or the increase in muscle fiber size. For muscular endurance and hypertrophy, you would use a lower weight, roughly 6585% of your one RM, and 8 to 12 repetitions for one to three sets.

The third type of muscular training is called muscular power, which is the amount of work performed per unit of time. This is a quick movement involving two strategiesthe most traditional is to aim for a heavy load, typically over 90% of your 1 RM, with only one to four repetitions.

Again, using our example of one RM bench press of 100 lb, you would lift 9095 lb for just one to two reps. You would likely take long breaks between sets with this style of lifting.

Alternatively, because muscular power is based on how fast the movement can be completed, you can also use a light loadit could even be your body weightor a load that is somewhere around 50% of one RM and then perform the movement fast. Of course, the style you choose is based on your goals, and working with a coach is highly recommended given the technical aspects of doing this safely. The main idea is to move the load as fast as possible.

Thus, in order to increase your muscle mass, effort is required when youre at the gym. If you like to lift and to do aerobic exercise, then dont worry too much about whether you do cardio or resistance training first when you work out.

Lets assume you want to lift weights. You might think you should do a total body routine or split the body segments into working your legs one day and your upper body on a second day.

However, many other variations exist like chest and triceps on day one, then back, biceps, and shoulders on day two, and legs on day three. It can be confusing without proper guidance.

To settle this argument, researchers recruited 20 resistance-trained young men and had them perform two to three sets of eight to 12 repetitions for a total of 18 sets per session for eight weeks. They used either a one-day-per-week, split-body routine where multiple exercises were done for two to three muscle groups per session, or a three-day-per-week, total-body routine where one exercise was performed per muscle group per session with all muscle groups trained.

The researchers tested the upper and lower body strength and muscle size. After eight weeks, they noted no differences except for greater increases in the size of the forearm flexors in the total-body routine compared to the split-body routine.

In the end, Professor Ormsbee recommends developing a weight training program that you like and that you can stick to.

Michael Ormsbee is an Associate Professor in the Department of Nutrition, Food, and Exercise Sciences and Interim Director of the Institute of Sports Sciences and Medicine in the College of Human Sciences at Florida State University. He received his MS in Exercise Physiology from South Dakota State University and his PhD in Bioenergetics from East Carolina University.

Lack of touch: Carleton University professor on what it means to our well-being – CTV News Ottawa

OTTAWA -- No handshakes, no hugs, for many, especially our elderly, no physical contact from loved ones; this is the collateral pain of COVID-19.

Visits through panes of glass, or no visiting at all, is the imagery defining this pandemic. Keeping us safe from a virus has kept us physically apart.

We count on technology to stay in touch with loved ones, but can tech compare with touch?

Carleton University professor in neuroscience Alfonso Abizaid says tech is not touch, and the lack of touch is hard on our health, both mentally and physically.

"Like hunger for food, humans have evolved mechanisms that produce cravings for social interactions and depletion of social interactions lead to stress," explains Abizaid.

If you cannot be with the ones you love, Abizaid suggests having something of theirs to hold.

"I think of my lovely mother-in-law, Julie, who is an amazing knitter. She knits sweaters and blankets for our kids," said Abizaid.

A lot of the time when you look at my kids, and theyre snuggling, they always grab those blankets because they have, in addition to being comfy and warm and fuzzy, they were made by their grandmother, so it makes them think of their grandmother.

When asked about grandparents missing physical contact, Abizaid suggests:

"Maybe if the families, the children and the grandkids can bring a teddy and send a nice message, 'hug it and when you hug it think of us will be hugging you back.'"

Abizaid says it is so interesting that a physical object can offer comfort.

"Its not only texture and how a material feels on the skin; its the association being made between that object and a particular person," says Abizaid.

We are creatures that do benefit from vicarious experiences, and having some item to hug that is clearly associated with those we love may provide for respite."

Abizaid explained the importance of touch to our physiology, and psychology, on CTVs News at Noon and how our pets, our therapy animals, he explains, play a role in our health.

"Pets like cats and dogs, who incidentally also benefit from the interaction, can provide the sensory information that can help mitigate the pandemic isolation effects on mental health."

Abizaid refers to decades old psychological studies illustrating the importance of physical affection and contact.

"To attain the full positive effects of social interactions we require the sense of touch. Our skin transmits touch information to brain centers that stimulate hormones like oxytocin, which are important for the formation of social bonds and the development of brain regions that allow individuals to socialize and form as they grow and integrate with their social group," said Abizaid.

Being deprived of this important sensory information is highly aversive, and over prolonged periods of time, it could lead to disruptions on how the brain works."

Abizaids lab work looks at how the brain attains what biologist's term homeostasis, which refers to a state in which we are at a comfortable balance.

When discussing homeostasis, people often use body temperature or energy as examples of homeostasis and I do study these mechanisms in detail, specifically how the brain works to attain temperature or energy balance.

It has become increasingly obvious, according to the professor, especially with the pandemic, there are also mechanisms that are associated with "social homeostasis", a sort of balance in the way we interact with others and that when imbalanced, it can lead to diseases.

"Because getting out of any of these homeostatic comfort zones leads to stress and prolonged episodes of stress can lead to all kinds of physiological and psychological pathological states."

Professor Abizaid on how we know this:

Professor Abizaid says hug those you can, when you can.

Cuddle your pets, or even your cozy blankets.

"Having support care takers that hug those that are socially isolated is also helpful, as long as measures that prevent transmission are taken, and finally support animals can also provide a source of comfort."

Dr. Abizaid is interested in how the brain deals with stress. This is the Carleton University project he, and his colleagues, published relating to COVID-19.
