Researchers found that Raloxifene stimulated the growth of ovarian cancer cell lines, raising concerns about its use in ER+ patients. The study advises caution when prescribing Raloxifene to women with a history of breast cancer and ovarian cancer.
Researchers discovered high levels of hydroxyl (OH) radical in the near-surface atmosphere over the South Pole, exceeding equatorial values. The findings suggest that glacio-chemists must be cautious when interpreting Antarctic ice cores, as changes in chemical species may continue for years after being trapped in the snowpack.
A comprehensive analysis of aquatic bird genes reveals that flamingos are closely related to grebes, contrary to their physical appearance. The study suggests that evolutionary change occurred at a faster pace than previously recognized, with physical features evolving repeatedly in different species.
A Smith College-sponsored expedition will retrace the original route of the Harriman Expedition, assessing ecological and societal changes in Alaska over the last century. The expedition aims to recreate E.H. Harriman's 'floating university' with leading scholars and researchers.
Zoologists at UC Berkeley have discovered a new species of salamander in southeastern Mexico that was mistaken for another species due to identical appearance. DNA analysis revealed the two species evolved from different ancestors despite shared adaptations to burrowing.
Scientists have discovered a significant component of the ocean's carbon cycle, with photosynthetic bacteria found in virtually every surface water sample. These aerobic photoheterotrophic bacteria can produce organic matter and supply up to 40% of their energy from sunlight.
Researchers found that HAART decreased the HIV death rate to 38 percent of pre-HAART levels and opportunistic infections to 66 percent, supporting its effectiveness in advanced patients. The study analyzed data from 528 advanced AIDS patients who received HAART for an average of 15 months.
A new study has found that children conceived through assisted reproduction have stable and satisfying marriages, psychologically healthy parents, and well-adjusted children. The research also suggests that the absence of a genetic link between fathers and children does not interfere with developing positive relationships.
The Michigan Media Award for Excellence in Coverage of Women and Gender recognizes outstanding media coverage of issues concerning women. This year's winners, Susan Ferraro (New York Daily News) and Women's E-news, were selected for their excellent coverage of women's health care issues and neglected topics.
Couples seeking preimplantation genetic diagnosis (PGD) for single gene disorders or to avoid chromosomal abnormalities have differing views on embryo destruction and genetic trait selection. The study found that most couples prioritize having a healthy child over preventing genetic transmission of inherited mutations.
The Ohio State genome map contains 66,000 genes, which is more than double the earlier estimates of 35,000 genes. The map provides annotations that explain the function of all genes, including tissue-specific genes that are active in some tissues but not others.
A new study, involving over 400 families from four European countries, has found no evidence of emotional problems among ART parents. The research also revealed that ART fathers have a warmer and less authoritarian relationship with their children.
Researchers have discovered a potential cause of male infertility, identifying the ZNF214 gene as a candidate gene. The gene is linked to impaired spermatogenesis and may be inherited from mothers. Further research will help understand its role in sperm production and develop targeted treatments.
The European Society of Human Reproduction and Embryology is advocating for testosterone therapy in older men due to the increasing prevalence of age-related symptoms such as low energy, depression, and erectile dysfunction. Testosterone replacement therapy has been shown to alleviate these symptoms, particularly in men over 50 years old.
A team of scientists discovered a stable strain of bacteria living in a specific type of sea sponge, found along the Great Barrier Reef near Australia. The presence of this bacterium is linked to the health of the sponge and has potential as a model for finding new medicinal compounds.
Researchers found that raloxifene stimulates cell growth in ovarian adenocarcinoma cells with estrogen receptors, increasing the risk of recurrence. The study suggests caution for women with a history of breast cancer and estrogen receptor-positive ovarian cancer.
The number of multiple births per embryo transfer decreased from 29.6% to 26.3% in Europe between 1997 and 1998. The proportion of twin deliveries fell from 25.8% to 23.9%, while triplet births declined from 3.6% to 2.3%.
Scientists have found that teenage girls with Turner's syndrome still possess follicles in their ovaries, which may enable them to produce eggs. This breakthrough discovery provides a glimmer of hope for these women who are usually infertile due to the syndrome. Further research is needed to confirm the findings and explore the possibi...
The study suggests KETEK is an effective option for treating community-acquired respiratory tract infections, which cause 50 million deaths globally each year. KETEK demonstrated high activity against a range of bacteria, including pneumococci and S. pyogenes, with up to 99.6% susceptibility
A new study suggests tamoxifen may decrease risk of first breast cancer but increase risk of estrogen-receptor negative, more difficult-to-treat contralateral tumors in the opposite breast.
A recent study published by the European Society of Human Reproduction and Embryology found that women who smoke more than 10 cigarettes a day have a significantly lower chance of IVF success. The implantation rate for non-smokers was 22.7%, compared to 15.1% for women smoking over 10 cigarettes a day.
Research suggests that bowel cancer screening strategies targeting solely individuals with a family history may have limited impact on reducing mortality from colorectal cancer. In fact, the study found that around 85% of bowel cancers develop in people without a family history, highlighting the need for more widespread screening.
A UCSF study reveals that uninsured patients with chronic illnesses face significant challenges in managing their conditions, including poor symptom recognition and limited access to medication. This can lead to greater illness severity and premature death. Free community clinics are crucial for addressing these disparities.
