Researchers found that nanoparticles release nitric oxide to kill Proprionobacterium acnes bacteria and inhibit inflammation. This approach may lead to better treatment options for acne and other inflammatory skin conditions.
A study of 200 adult men found that those with borderline testosterone levels had a 56% rate of depression and depressive symptoms, highlighting the importance of screening for mental health in this population. The researchers also identified high rates of obesity and low physical activity as contributing factors.
A new study found that certain immune responses may play a role in blocking systemic HIV infection after exposure. T-cell responses against specific HIV-1 antigens were significantly higher and more frequent among those who remained uninfected compared to those who became infected, associated with reduced risk of infection.
Researchers have identified a biomarker for advanced bile duct fibrosis and bile duct cancer caused by the Asian Liver Fluke, allowing for earlier detection and potentially saving lives. The Thai Ministry of Health has implemented testing for this biomarker in endemic regions to identify individuals at risk.
A study of over 12 million bacteria found that E. coli antimicrobial resistance to ciprofloxacin increased five-fold from 2000 to 2010, making treatment more expensive and complex for patients. The lack of new antimicrobial drug development is a major concern, as it may lead to the use of less effective and potentially toxic treatments.
GW researchers are evaluating innovative methods to assess the immune response to vaccines with a novel Toll-like Receptor (TLR)-4 agonist adjuvant. They will use new antibody profiling techniques to determine the quality of the humoral immune response in humans.
Researchers found that chimpanzees switched to two legs in high-competition situations to carry more resources. This adaptation may have led to natural selection and the origin of human bipedalism.
The study identified biologically relevant targets in breast cancer using mRNA sequencing, revealing novel and unannotated transcripts. The GW research team discovered common and differentially expressing transcripts between three types of breast cancer, shedding light on the disease's underlying mechanisms.
A study published in Environmental Health Perspectives found that men with higher levels of DDE and PCBs had significantly higher rates of sperm abnormalities. Researchers used a new sperm imaging methodology to detect chromosomal abnormalities, highlighting the potential impact of environmental exposure on male fertility.
Researchers aim to identify mechanisms that define embryonic olfactory epithelium stem cells, which are linked to neurological and psychiatric diseases such as Parkinson's and Alzheimer's. The goal is to harness these mechanisms for brain repair and regeneration.
Researchers will use a quantitative proteomics approach to identify biomarkers for bile duct cancer in patients infected with Opisthorchis viverrini. The study aims to develop early diagnostic tools for this deadly disease, which affects over 40 million people in Southeast Asia.
Researchers at George Washington University School of Medicine and Health Sciences have shown that the Mta1 gene is essential for Schistosoma haematobium to establish a productive infection and survival in the host. The study found that mice lacking the Mta1 gene were unable to support worm growth and egg production, highlighting the c...
Researchers at George Washington University have identified 18 novel genetic markers for autism spectrum disorders, highlighting four distinct subtypes and ten associated variants. These findings provide potential genetic biomarkers for diagnostic screening and advance the understanding of autism's genetic contributions.
Scientists found that a protein called Igf2 in the cerebrospinal fluid signals brain cells to multiply during embryonic development. This discovery could lead to new treatments for neurological diseases and cancer by targeting specific areas of the brain, eliminating the need for localized drug delivery.
Researchers found a gene called RORA that plays a critical role in brain development and is affected by sex hormones. In individuals with autism, aromatase conversion of testosterone to estrogen is reduced, leading to increased male hormone levels and decreased RORA expression.
Scientists have discovered an accomplice in breast cancer – a master control switch with the power to set off a cascade of reactions orchestrated by a cancer-causing gene named Wnt1. The executive molecule MTA1 is reported to trigger cancer-causing signals from Wnt1 in human breast cancer cells, leading to tumors.
Dr. Anthony-Samuel LaMantia's research identifies stem cells responsible for generating nerve cells involved in eating, reproduction, and social behavior. These cells are essential for understanding neurological and mental disabilities, such as autism, schizophrenia, and Alzheimer's disease.
A new analysis by George Washington University Medical Center found that 15% of hospitality industry employees suffer from serious alcohol-related problems. Workplace screening and brief intervention can help reduce excessive alcohol use in the workplace.
