Tohoku University scientists have, for the first time, provided experimental evidence that cell stickiness helps them stay sorted within correct compartments during development. How tightly cells clump together, known as cell adhesion, appears to be enabled by a protein better known for its role in the immune system. The findings were detailed in the journal Nature Communications.
This summer, when bars and restaurants and stores began to reopen across the United States, people headed out despite the continuing threat of COVID-19.
As a result, many areas, including the St. Louis region, saw increases in cases in July.
Lifestyle, or put another way 'bad habits', is one of the textbook explanations for why some people are at higher risk for cancer. We often hear that smoking increases our risk of developing lung cancer or that a high-fat diet increases our risk of developing bowel cancer, but not all smokers get lung cancer and not all people who eat cheeseburgers get bowel cancer. 'Other factors' must be at play.
Researchers at the Kobe University Graduate School of Medicine have revealed that alterations in fetal microglia (*1) resulting from maternal inflammation could contribute towards the onset of developmental and psychiatric disorders. The research team including PhD student OZAKI Kana and Professor YAMADA Hideto et al. from the Department of Obstetrics and Gynecology observed that infant mice that were exposed to maternal immune activation (MIA mice) displayed changes in microglial process motility during gestation and development.
Dr. J. James Frost and The International Journal of Unconventional Computing will soon be publishing "Cancer's Intelligence" which reports that Cancer can be analyzed as an intelligent system of collaborating and computing cells.
LAWRENCE -- To be fair, the newly described Waray Dwarf Burrowing Snake (Levitonius mirus) is pretty great at hiding.
In its native habitat, Samar and Leyte islands in the Philippines, the snake spends most of its time burrowing underground, usually surfacing only after heavy rains in much the same way earthworms tend to wash up on suburban sidewalks after a downpour.
MINNEAPOLIS - Just like with drug costs, the amount of money people pay out-of-pocket for diagnostic tests and office visits for neurologic conditions has risen over 15 years, according to a new study published in the December 23, 2020, online issue of issue of Neurology®, the medical journal of the American Academy of Neurology. The study, funded by the American Academy of Neurology, found that people enrolled in high-deductible health plans were more likely to have high out-of-pocket costs than people in other types of plans.
MINNEAPOLIS - A new study has found that while the prevalence of neurologic conditions like dementia, stroke, Parkinson's disease and multiple sclerosis (MS) is consistent across the U.S., the distribution of neurologists is not, and people in more rural areas may be less likely to receive specialty care for certain neurologic conditions. The study, funded by the American Academy of Neurology, is published in the December 23, 2020, online issue of Neurology®, the medical journal of the American Academy of Neurology.
How the immune system adapts to pregnancies has puzzled scientists for decades. Now, findings from an international group of researchers, led by researchers at Karolinska Institutet in Sweden, reveal important changes that occur in the thymus to prevent miscarriages and gestational diabetes. The results are published in the journal Nature.
Charismatic, iconic and Instagram-friendly, the weedy seadragon is a favourite with divers and snorkellers. The first genomic study of east coast Australian seadragon populations can now reveal "weedies" from NSW, Victoria and Tasmania are significantly different.
The study, published in PLOS ONE, also reveals that Victorian weedy seadragons may form a subspecies which has implications for conservation management. The researchers recommend that, as a precautionary approach, these distinct populations be managed separately by each state.
An international research team led by the University of British Columbia (UBC) has uncovered for the first time the importance of a small gland tucked behind the sternum that works to prevent miscarriage and diabetes in pregnant women.
The organ in question is the thymus, identified in a study published today in the journal Nature as playing a significant role in both metabolic control and immunity in pregnancy.
Female sex hormones instruct the thymus, a central organ of the immune system, to produce specialized cells called "Tregs" to deal with physiological changes to arise during pregnancy, the study revealed. The researchers also found that RANK, a receptor expressed in a part of the thymus called the epithelium, is the key molecule behind this mechanism. The study is an international research effort including scientists from IMBA, the University of British Columbia, the Karolinska Institutet and the Medical University of Vienna.
PHILADELPHIA -- (Dec. 23, 2020) -- Wistar Institute scientists have discovered a new class of compounds that uniquely combine direct antibiotic killing of pan drug-resistant bacterial pathogens with a simultaneous rapid immune response for combatting antimicrobial resistance (AMR). These finding were published today in Nature.
As COVID cases rise, physically distancing yourself from other people has never been more important. Now a new UCLA study reveals how your brain navigates places and monitors someone else in the same location.
Published Dec. 23 in Nature, the findings suggest that our brains generate a common code to mark where other people are in relation to ourselves.
GAINESVILLE, Fla. --- The history of the Caribbean's original islanders comes into sharper focus in a new Nature study that combines decades of archaeological work with advancements in genetic technology.
