Research breakthrough could see HIV drugs used to treat low-grade brain tumors
Drugs developed to treat AIDS and HIV could offer hope to patients diagnosed with the most common form of primary brain tumor. The breakthrough is significant because, if further research is conclusive, the anti-retroviral drugs could be prescribed f.....»»
A missing genetic switch at the origin of malformations
Embryonic development follows delicate stages: for everything to go well, many genes must coordinate their activity according to a very meticulous scheme and tempo. This precision mechanism sometimes fails, leading to more or less disabling malformat.....»»
Vaccines and previous infection could offer some "stronger than basic" protection to Omicron, early study suggests
One of the earliest, peer-reviewed studies looking into the Omicron variant of COVID-19 suggests that people previously infected with COVID, and those vaccinated, will have some, 'stronger than basic' defence against this new strain of concern......»»
Infant immune systems are stronger than you think, research shows
Immunologists have found that the infant immune system is stronger than most people think and beats the adult immune system at fighting off new pathogens......»»
Chemicals from hair and beauty products impact hormones, especially during pregnancy
The use of certain personal care products during pregnancy may impact maternal hormone levels, according to a new study......»»
A longer-lasting COVID vaccine? New study points the way
Researchers have identified rare, naturally occurring T cells that are capable of targeting a protein found in SARS-CoV-2 and a range of other coronaviruses. The findings suggest that a component of this protein, called viral polymerase, could potent.....»»
Getting childhood obesity initiatives across the finish line
Too often, strategies proven in research studies to reduce pediatric obesity are never implemented in the 'real world.' Researchers describe a school-based program that gets these interventions across the finish line by inviting schools to tailor the.....»»
Seasonal temperature impacts patient lab results
Ambient temperature influences the results of some of the most used laboratory tests, and these distortions likely affect medical decision making, such as whether to prescribe medications, researchers report. The authors say that laboratories could s.....»»
Scientists identify malfunctioning brain cells as potential target for Alzheimer"s treatment
Scientists have identified a rare population of potentially toxic senescent cells in human brains that can serve as a target for a new Alzheimer's disease treatment......»»
First structure of human protein complex with "license to kill"
A team of researchers has for the first time visualized a human cell death complex linked to autoimmune and inflammatory conditions, such as inflammatory bowel disease, and injuries associated with excessive cell death......»»
Melatonin exacerbates asthma, study finds
Asthma sufferers generally find their condition gets worse at night. Now researchers may understand why. Melatonin, a sleep hormone that is sometimes prescribed to treat insomnia, exasperates the constriction of the bronchus -- the pathway that moves.....»»
Aging stiffens the blood vessels but their flexibility also fluctuates based on a woman’s hormone state
A study measured arterial stiffness in women from wide age range. Increased stiffness is an independent risk factor for cardiovascular disease. Age was a strong determinant of arterial stiffness. Indicative of the role of hormones, menstrual cycle ph.....»»
Study on genetic changes in neuroblastoma
When cells within a single tumor differ in terms of their genetic makeup, this is referred to as intratumor heterogeneity. Researchers have been able to reconstruct the process by which this genetic heterogeneity develops in neuroblastoma, a type of.....»»
Innovative silicon nanochip can reprogram biological tissue in living body
A silicon device that can change skin tissue into blood vessels and nerve cells has advanced from prototype to standardized fabrication, meaning it can now be made in a consistent, reproducible way......»»
Doctoral student finds alternative cell option for organs-on-chips
Organ-on-a-chip technology has provided a push to discover new drugs for a variety of rare and ignored diseases for which current models either don't exist or lack precision. In particular, these platforms can include the cells of a patient, resultin.....»»
New biosensors shine a light on CRISPR gene editing
Detecting the activity of CRISPR gene editing tools in organisms with the naked eye and an ultraviolet flashlight is now possible using new technology......»»
A step toward "living biotherapeutics"
Chemical engineers have developed a protective coating that helps anaerobic microbes survive the manufacturing process, making it potentially easier to use them to treat gastrointestinal disease......»»
Family dynamics can motivate and prevent talking about health
New research explores how family dynamics factor into whether 18- to 25-year-olds share private health information and involve their parents when making medical decisions. Having open and respectful conversations and reciprocal information sharing ea.....»»
Two-year follow up shows delaying umbilical cord clamping saves babies’ lives
A new study finds that aiming to wait just 60 seconds to clamp the umbilical cord of very premature babies at birth continues to have benefits two years on - decreasing the child's risk of death or major disability......»»
Key step toward personalized medicine: Modeling biological systems
A new study shows that machine learning techniques can offer powerful new tools for advancing personalized medicine, care that optimizes outcomes for individual patients based on unique aspects of their biology and disease features......»»
