Researchers at UNC identified two key genes involved in blood vessel development: BMPER and HOXB5. The study found that BMPER inhibits further differentiation of endothelial cells, while HOXB5 activates the endothelial cell program, increasing vessel formation.
Researchers found that loss of <i>H2AX</i> gene leads to increased genomic instability and cancer in mice. The study suggests that <i>H2AX</i> deficiency may be a major player in cancer-causing genomic instability, particularly in the context of human tumors with alterations in chromosome 11.
A recent study reports a correlation between declining vaccinations and increasing measles outbreak sizes in the UK. The reproductive number, measuring the spreadability of measles, has increased to approach endemic disease levels.
Scientists have developed a new adaptation of seismic reflection profiling to create detailed pictures of oceanic features, including eddies and internal waves. This technique has the potential to improve our understanding of ocean mixing and its role in climate modeling.
Researchers at Project A.L.S. have successfully tested a gene therapy approach that delays disease progression and prolongs survival in a mouse model of ALS. The treatment uses an adeno-associated viral vector to express the IGF1 protein, promoting neuronal survival.
Researchers at the University of Pittsburgh School of Medicine found that only 16% of pregnant women with parvovirus B19 exhibited symptoms, while 12% experienced fetal heart failure and 16% suffered fetal death. The study highlights the need for closer monitoring and counseling of high-risk patients.
A UCLA study discovered that fatigued breast cancer survivors have increased levels of circulating T lymphocytes and CD4+ T cells, which correlate with elevated inflammation markers. The findings suggest an immunologic basis for fatigue in breast cancer survivors.
A new study by Ohio State University researchers found that eight autistic children who participated in the Early Intensive Behavioral Intervention (EIBI) program showed significant improvements in IQ scores and adaptive behavior. Six of the children achieved average IQ scores, while two improved to mild mental retardation.
Researchers at UT Southwestern Medical Center have identified phosphatidylinositol 4 phosphate (PI4P) as the main regulator of membrane trafficking in the Golgi. This finding debunks a decade-old theory and provides insight into the vital process of cell survival.
Researchers found that injecting a gene producing insulin-like growth factor-1 (IGF-1) into muscles delayed disease onset by 31 days, preserved nerve cells, and reduced muscle wasting. This study may lead to a new, gene-based treatment for ALS affecting over 30,000 Americans.
A new study published in The Lancet found that the meningococcal C conjugate vaccine (MCCV) may increase relapse rates of nephrotic syndrome in children with kidney disease. The vaccine was introduced to all UK children under 18 years old in 1999, but subsequent monitoring revealed a 30% increase in relapses post-vaccination.
The American Association for Cancer Research (AACR) is seeking nominations for its Professorship in Basic Cancer Research, which provides a $50,000 grant for research expenses. The AACR-NFCR Professorship was established to honor Franklin and Tamara Salisbury and support cutting-edge basic cancer research.
Researchers at Johns Hopkins and Salk Institute develop gene therapy that slows progression of amyotrophic lateral sclerosis (ALS), a devastating disease affecting thousands. In experiments with mice, injection of insulin-like growth factor-1 (IGF-1) into muscles extends survival and improves strength.
The study improved forecast accuracy for a major winter snowstorm in Washington, D.C. and demonstrated the potential to enhance storm tracking and predict snowfall amounts.
The American Association for Cancer Research (AACR) is accepting nominations for several prestigious awards and lectureships, recognizing outstanding contributions in epidemiology, clinical cancer research, and preclinical research. The deadline for submissions is September 12, 2003.
A multicentre hospital-based case-control study found that transdermal estrogen replacement therapy is not associated with an increased risk of venous blood clots in postmenopausal women. In contrast, oral estrogen replacement therapy was linked to a significantly higher risk of developing venous thromboembolism.
Researchers found that antidepressants stimulate new neuron creation, which takes several weeks, and that this process is crucial for clinical response. The study also highlights the importance of specific serotonin receptors in regulating emotions.
Researchers found that genetic super-combinations from hybridization can create advantageous traits for survival and reproduction. They demonstrated a possible mechanism for rapid evolutionary change through replicating the births of three unusual species within a few generations.
Georgia Tech researchers develop packet-level simulation capable of modeling over 1 million web browsers in near real time. The breakthrough offers new capabilities for engineers and scientists to analyze large-scale computer networks and find solutions to Internet problems.
A Penn State study reveals that low-maintenance lawns harbor higher populations of beneficial arthropods, such as mites and collembolans, while high-maintenance lawns experience reduced diversity due to chemical applications and mowing.
Researchers discovered a genetic signature that identifies genes targeted by RNA editing, which is primarily confined to the nervous system across species. This breakthrough improves the value of existing genome sequences and may hasten neurological research.
A substantial increase in breast cancer risk is associated with combination hormone replacement therapy, particularly oestrogen-progestogen therapy. Current users of HRT have a 22% increased risk of death from breast cancer compared to never-users.
Researchers identify unsuspected gene C/EBP-beta as key mediator of cyclin D1 action in human tumors. The technique combines data from the Global Cancer Map and gene chips to pinpoint gene interactions that lead to cancer.
A Johns Hopkins study found that home visits from community health workers led to a 4.5 mmHg systolic and 4 mmHg diastolic blood pressure reduction, with the percentage of participants controlling their blood pressure doubling over three years.
Researchers discover new method to produce acetic acid directly from methane, reducing production costs and environmental impact. The breakthrough uses a palladium-based catalyst, but further development is needed to achieve commercial viability.
Researchers at Vanderbilt University have identified a distinct pattern of protein expression that can predict poor or good lung cancer prognosis. The protein profile was used to analyze tiny amounts of tumor tissue and accurately distinguish between different types of lung cancer.
