Potential drug target revealed to help more children survive a lethal heart defect. When children are born with hypoplastic left heart syndrome (HLHS), they require a series of major surgical procedures to survive. But even with a repaired heart, as many as one in four children die from complications before age 25. Now, a study published by a new faculty member at Cincinnati Children’s reports a potential therapeutic target that might promote heart cell regeneration even before birth. Details were published online Aug. 17, 2020, in Cell Stem Cell, article: Intrinsic Endocardial Defects Contribute to Hypoplastic Left Heart Syndrome

New gene therapy approach eliminates at least 90% latent herpes simplex virus 1. Infectious disease researchers at Fred Hutchinson Cancer Research Center have used a gene-editing approach to remove latent herpes simplex virus 1, or HSV-1, also known as oral herpes. In animal models, the findings show at least a 90% decrease in the latent virus, enough researchers expect that it will keep the infection from coming back. The study: Gene editing and elimination of latent herpes simplex virus in vivo, published August 18 in Nature Communications, used two sets of genetic scissors to damage the virus’s DNA, fine-tuned the delivery vehicle to the infected cells, and targeted the nerve pathways that connect the neck with the face and reach the tissue where the virus lies dormant in individuals with the infection.

Researchers identify enzyme-linked to colitis. An enzyme that usually stops bacterial growth in the large intestine stimulates inflammation in some people, resulting in ulcerative colitis—a chronic digestive disease that affects more than 750,000 Americans, according to scientists at Rutgers University-Newark. In a new study published in Immunity, lead author Nan Gao, Associate Professor of Cell Biology in the Department of Biological Sciences, School of Arts and Sciences-Newark, reports that in people with ulcerative colitis, the gut enzyme lysozyme which normally functions to restrain bacterial growth instead stimulates inflammation.

Researchers get a first-ever look at a rare but vital stem cell in humans. Neutrophils are the warriors of the immune system. They are always ready to spring to action to help heal injuries or fight off disease. Unless, that is, something goes wrong in their developmental process. Immature neutrophils aren’t all warriors—they can be dangerous turncoats. High levels of immature neutrophils in the bloodstream can be a tell-tale sign of cancer and may even be a biomarker for COVID-19. Now scientists at La Jolla Institute for Immunology (LJI) have tracked down the rare stem cells that generate neutrophils in the human bone marrow. This research: Coexpression of CD71 and CD117 identifies an early unipotent neutrophil progenitor population in human bone marrow, published August 18, 2020, in Immunity, gives researchers a potential path for intervening in diseases where neutrophil development goes awry.

Study finds physical activity is beneficial for health, and more intense activity is better. Physical activity of any intensity is beneficial for health, but more intense activity has greater benefits, according to a new study: Wearable-device-measured physical activity and future health risk, published today in Nature Medicine. In the largest study to date of accelerometer-measured physical activity, a team led by researchers at the Medical Research Council (MRC) Epidemiology Unit at the University of Cambridge analyzed data from more than 96,000 UK Biobank participants.

A new study: ROR1 is upregulated in endometrial cancer and represents a novel therapeutic target, has identified a key gene in aggressive endometrial cancer, which could lead to a targeted therapeutic strategy to improve survival rates. UNSW Sydney medical researchers have identified the gene known as ROR1 as a future target for therapeutic treatment of aggressive endometrial cancer.

High-intensity physical activity in early adolescence could lead to stronger bones in adulthood. High-intensity physical activity in early life might help maximize peak hip strength and prevent osteoporosis in later life, according to a study: Physical Activity Throughout Adolescence and Peak Hip Strength in Young Adults, from University of Bristol researchers published in JAMA Network Open. The research, which analyzed data from 2,569 participants of the Children of the 90s health study, found that more time spent doing moderate-to-vigorous intensity physical activity (MVPA) from age 12 years was associated with stronger hips at age 25 years, whereas time spent in light intensity activity was less clearly associated with adult hip strength.

Study shows the way an object is named is instrumental in infants’ memory of an object. A pair of researchers at Northwestern University have found that the way an object is named by an adult is instrumental in an infant’s memory of that object. In their paper: Naming guides how 12-month-old infants encode and remember objects, published in Proceedings of the National Academy of Sciences, Alexander LaTourrette and Sandra Waxman describe experiments they conducted with memory in infants and what they learned from them.

Connection found between the degree of sleepiness and social interaction. A team of researchers from the Karolinska Institutet and Stockholm University has found a connection between how sleepy people are and how much they socialize. In their paper: Sleepiness, sleep duration, and human social activity: An investigation into bidirectionality using longitudinal time-use data, published in Proceedings of the National Academy of Sciences, the group describes their study of sleep and socializing patterns for a group of volunteers and what they learned from it.

Researchers find a method to regrow cartilage in the joints. Researchers at the Stanford University School of Medicine have discovered a way to regenerate, in mice and human tissue, the cushion of cartilage found in joints. Loss of this slippery and shock-absorbing tissue layer, called articular cartilage, is responsible for many cases of joint pain and arthritis, which afflicts more than 55 million Americans. Nearly one in four adult Americans suffer from arthritis, and far more are burdened by joint pain and inflammation generally. The Stanford researchers figured out how to regrow articular cartilage by first causing slight injury to the joint tissue, then using chemical signals to steer the growth of skeletal stem cells as the injuries heal. The work (Articular cartilage regeneration by activated skeletal stem cells and Elucidating the fundamental fibrotic processes driving abdominal adhesion formation) was published Aug. 17 in the journal Nature Medicine.

Constructing odor objects in the brain. A research team led by Hokto Kazama at the RIKEN Center for Brain Science (CBS) in Japan has combined brain imaging and models of brain activity to explain how smells can be generalized into categories. The team examined a region of the fly brain that plays a central role in forming olfactory memories and discovered clustered representations of mixtures and groups of odors that are conserved across individual flies. This study: Synthesis of Conserved Odor Object Representations in a Random, Divergent-Convergent Network, published in Neuron, explains how varying odors are perceived similarly in different individuals.

Romantic relationship dynamics may be in our genes. Variations in a gene called CD38, which is involved in attachment behaviour in non-human animals, may be associated with human romantic relationship dynamics in daily life, according to a study: CD38 is associated with communal behavior, partner perceptions, affect and relationship adjustment in romantic relationships, published in Scientific Reports.

Acidic niche keeps the lymphatic system in check during the immune response. In the fight against cancer, the immune system is the first line of defence. The lymphatic system specifically is essential to protecting the body against foreign invaders. Activation of immune cells in the lymph nodes leads to the production and release of antibodies, and activation of lymphocytes, including T cells, to battle infection. But little is known about how activation of immune cells in the lymph nodes can occur without enabling effector functions that could also damage the lymphatic system. In a new article: T-cells produce acidic niches in lymph nodes to suppress their own effector functions, published in Nature Communications, Moffitt Cancer Center researchers describe a novel acidic niche within lymph nodes that plays an integral role in regulating T cell activation.

Heart attack damage reduced by shielded stem cells. Bioengineers and surgeons from Rice University and Baylor College of Medicine (BCM) have shown that shielding stem cells with a novel biomaterial improve the cells’ ability to heal heart injuries caused by heart attacks. In a study using rodents, a team led by Rice’s Omid Veiseh and Baylor’s Ravi Ghanta showed it could make capsules of wound-healing mesenchymal stem cells (MSCs) and implant them next to wounded hearts using minimally invasive techniques. Within four weeks, heart-healing was 2.5 times greater in animals treated with shielded stem cells than those treated with nonshielded stem cells, the researchers found. The study: Immune-modulatory alginate protects mesenchymal stem cells for sustained delivery of reparative factors to ischemic myocardium, is available online in the Royal Society of Chemistry journal Biomaterials Science.

Targeted therapy combination effective for patients with advanced cholangiocarcinoma and BRAF mutations. In a Phase II trial led by researchers at The University of Texas MD Anderson Cancer Center, the combination of dabrafenib, a BRAF inhibitor, and trametinib, a MEK inhibitor, achieved a 51% overall response rate (ORR) in patients with cholangiocarcinoma marked by the BRAF V600E mutation. This trial represents the first prospective study for patients with BRAF-mutated cholangiocarcinoma, or bile duct cancer, and suggests this targeted therapy combination could serve as a much-needed treatment option for patients with treatment-resistant advanced disease. The trial results were published today in Lancet Oncology.

Measuring the social networks of young adults with autism. As many have recently discovered, social connections are vital to a person’s wellbeing. While social isolation is a core challenge associated with autism, researchers from Drexel University’s A.J. Drexel Autism Institute have laid the groundwork to show how interpersonal relationships, and the resources they provide, could impact autistic youth’s adult outcomes. The study, “Social Capital and Autism in Young Adulthood: Applying Social Network Methods to Measure the Social Capital of Autistic Young Adults,” will be published in Autism in Adulthood.

The study hopes to encourage the use of new technology to reduce errors in DNA testing. Today’s DNA testing is highly accurate, but errors still occur due to the limited genetic information accessible with current technologies. These errors can have a serious impact on people’s lives. New technology has been shown to reduce the chances of false associations and should be more widely used, said Jianye Ge, Ph.D., Associate Professor and Associate Director of the Center for Human Identification at The University of North Texas Health Science Center at Fort Worth. In a study titled “How Many Familial Relationship Testing Results Could Be Wrong?” Dr Ge reviewed worldwide practices to assess the potential of errors. Co-author of the study is Dr Bruce Budowle, Director and Professor for the Center for Human Identification.

A poo transplant successfully treated a man who was brewing alcohol in his own gut.

How setting aside some ‘worry time’ can help reduce anxiety over COVID-19 lockdowns. Many New Zealanders will be feeling anxious, disappointed and even angry about the return of COVID-19 in the community. Many of us prefer to suppress these emotions because they are unpleasant or we may feel under-equipped to manage them. But if left unrecognized and unchecked, they will drive our behaviour.

Wide variation across hospitals in nurse staffing is a threat to the public’s health. According to a new study published today in BMJ Quality & Safety, many hospitals in New York and Illinois were understaffed right before the first surge of critically ill COVID-19 patients. The study, “Chronic Hospital Nurse Understaffing Meets COVID-19,” documented staffing ratios that varied from 3 to 10 patients for each nurse on general adult medical and surgical units. ICU nurse staffing was better but also varied significantly across hospitals.

These drugs carry risks and may not help, but many dementia patients get them anyway. Nearly three-quarters of older adults with dementia have filled prescriptions for medicines that act on their brain and nervous system, but aren’t designed for dementia, a new study shows.

New links found between diabetes blood markers and Alzheimer’s disease pathology. A new study: Association of Peripheral Insulin Resistance and Other Markers of Type 2 Diabetes Mellitus with Brain Amyloid Deposition in Healthy Individuals at Risk of Dementia, published in the Journal of Alzheimer’s Disease provides insight into the association of blood markers of diabetes with brain beta-amyloid accumulation among older people at risk of dementia. The results suggest a link between Alzheimer’s pathology, lower levels of insulin and lower insulin resistance.

Here’s why we crave food even when we’re not hungry. Food cravings are very familiar to most people. We may see or smell food and want to eat, or sometimes we suddenly feel like eating something delicious. These intense desires occur even when we’re not hungry and can be very difficult to resist. An interesting study: Impulsivity makes more susceptible to overeating after contextual appetitive conditioning, found that people could easily learn such associations when they were given a milkshake while being shown images on a computer screen. The participants reported greater desire for a milkshake when they were shown these images compared to when they were shown images that were not associated with the milkshake.

Fetal health negatively impacted by airplane noise. The likelihood of having a low birth weight (LBW) baby is increased if the mother lives close to the airport, in the direction of the runway, and is exposed to noise levels over the 55 dB threshold, a new University of Colorado Denver study found. Results come from a study conducted by Laura Argys, Ph.D., professor of economics at CU Denver, and her colleagues, Susan Averett and Muzhe Yang, examining residential neighbourhoods impacted by airplane flight patterns from one of the biggest airports in the nation—Newark Liberty International in New Jersey.

High fructose diet in pregnancy impacts the metabolism of offspring. Study finds an increased level of fructose intake during pregnancy can cause significant changes in maternal metabolic function and milk composition and alter the metabolism of their offspring, researchers from the University of Otago, Wellington, have found. The research: Fructose Consumption During Pregnancy Influences Milk Lipid Composition and Offspring Lipid Profiles in Guinea Pigs, which was led by Dr Clint Gray, a Research Fellow in the Department of Pediatrics and Child Health, found increasing the fructose in the diets of female guinea pigs led to highly significant and consistent changes in the free fatty acids circulating in the blood of their offspring. This was despite the offspring consuming no fructose themselves.

RNA as a future cure for hereditary diseases. ETH Zurich scientists have developed an RNA molecule that can be used in bone marrow cells to correct genetic errors that affect protein production. Patients suffering from a rare hereditary disease that causes a painful hypersensitivity to sunlight could benefit in future. Short RNA molecules can be used as medication. Their effectiveness is based on the genetic information they carry: therapeutic RNA can bind to the body’s own RNA and thus influence how it functions. However, only a handful of such drugs are available so far.

A bright idea: Genetically engineered proteins for studying neurons using light. In many human endeavours, having good tools for a particular task is an essential requirement to obtain the best results possible, and neuroscience is no different than other scientific fields in this regard. However, neuroscientists tackle the colossal objective of shedding light on the inner workings of neurons and neuronal circuits, and they rely on various methods to observe and control the firing of neurons to gain a better understanding of their functions. This new study by Japanese scientists: Green-Sensitive, Long-Lived, Step-Functional Anion Channelrhodopsin-2 Variant as a High-Potential Neural Silencing Tool, published in The Journal of Physical Chemistry Letters, expands the available options for optogenetic neuronal silencing and explores the potential of GtACR2, a natural light-regulated anion channel from an alga.

How protein protects against fatty liver. Non-alcoholic fatty liver disease is the most common chronic liver disease in the world, with sometimes life-threatening consequences. A high-protein, calorie-reduced diet can cause harmful liver fat to melt away—more effectively than a low-protein diet. A new study: High‐protein diet more effectively reduces hepatic fat than low‐protein diet despite lower autophagy and FGF21 levels, by DIfE/DZD researchers published in the journal Liver International shows which molecular and physiological processes are potentially involved.

Scan for the arterial plaque is better at predicting heart attack than stroke. The amount of calcified plaque in the heart’s arteries is a better predictor of future heart attacks than of strokes, with similar findings across sex and racial groups, according to new research: Predictive Value of Coronary Artery Calcium Score Categories for Coronary Events Versus Strokes: Impact of Sex and Race, from UT Southwestern.

Risk of diabetes complications increases with elevated levels of NT-proBNP
Healthy people—especially women—with elevated levels of heart failure marker NT-proBNP have a lower risk of developing type 2 diabetes. However, if these people develop diabetes nonetheless, they are more likely to suffer from macro- and microvascular complications such as heart attack, stroke, or severe damage to eyes, kidneys, or nerves. These are the findings of a recent study: Opposing Associations of NT-proBNP With Risks of Diabetes and Diabetes-Related Complications, by DZD researchers that have now been published in Diabetes Care.

Federal and state websites flunk COVID-19 reading-level review. Information about COVID-19 offered by the U.S. Centers for Disease Control and Prevention, the White House, and state health departments failed to meet recommendations for communicating with the public, according to a Dartmouth study: Comparison of Readability of Official Public Health Information About COVID-19 on Websites of International Agencies and the Governments of 15 Countries.

Decline in milk consumption by children in school lunch programs may affect future health. Fluid milk consumption among children is vital, as adequate consumption of dairy products, especially during childhood, has beneficial health outcomes later in life. These benefits include reduced risk of osteoporosis, hypertension, obesity, and cancer in adulthood. Milk consumption among children has been declining for decades, so understanding and fulfilling the needs of children is crucial to reverse the decline. In an article: Invited review: Maintaining and growing fluid milk consumption by children in school lunch programs in the United States, appearing in the Journal of Dairy Science, scientists from North Carolina State University and Cornell University studied key contributors to increasing milk consumption among children.

The new method proposed for preoperative needle insertion trajectory planning. Percutaneous needle insertion is a widely used technique in needle-based interventions. However, it is difficult to achieve high targeting accuracy due to needle deflection and the boundary effect in multilayered tissues. Researchers from the Shenzhen Institutes of Advanced Technology (SIAT) of the Chinese Academy of Sciences proposed a preoperative needle insertion trajectory planning method that includes needle deflection modelling, insertion angle correction and needle trajectory optimization. Their study: Needle Deflection Modeling and Preoperative Trajectory Planning during Insertion into Multilayered Tissues, was published in IEEE/ASME Transactions on Mechatronics on August 3.

The meanings of meat. Invitations to dinner more often entail the consumption of meat than does an evening meal alone at home. A new study: The meaning of meat: (Un)sustainable eating practices at home and out of home, by LMU researchers shows that the willingness to forego meat is highly context dependent.

First US face transplant recipient dies, leaving an important legacy. On December 9 2008, 45-year-old Connie Culp became the first person in the United States, and only the fourth in the world, to receive a face transplant. Connie’s transplant took a team at the Cleveland Clinic in Ohio more than 22 hours to perform and allowed her to eat solid food again, to smell, and to breathe independently. Four years earlier, Connie had been shot in the face by her husband, who was subsequently imprisoned for seven years for aggravated attempted murder. Sadly, Connie died on July 29 2020, of an as yet unspecified infection.
