Researchers from New York Medical College and University of California Davis have developed an individualized patient data meta-analysis to report the probability of live birth after in vitro fertilization (IVF) with frozen eggs. The study shows that egg freezing success rates decline with age, with a sharper drop after age 36.
Stuart A. Newman's alternative model suggests that the origination of animal form motifs was predictable and sudden, with abrupt morphological transformations favored during early evolution. This perspective resolves puzzling aspects of animal evolution, including the rapid rise of complex body forms.
A new study has found evidence of chronic traumatic encephalopathy (CTE) in brain tissue from blast-exposed military service personnel. Exposure to a single blast equivalent to an IED results in CTE and long-term brain impairments, similar to those seen in athletes with repetitive concussion injuries.
New York Medical College scientist Stuart A. Newman suggests that the loss of a gene critical for heat generation led to the emergence of enlarged skeletal muscles in birds, enabling them to walk on two legs and adapt to flying or swimming. This theory challenges traditional views on bird evolution and extinction
A new study suggests that improved Social Security benefits lead to lower mortality rates and increased life expectancy among people over 65. The researchers found that this demographic benefited most from the changes, with a 50% increase in decline rates following the introduction of Social Security in 1940.
A team of researchers discovered that tobacco-free cigarettes can cause more DNA damage than tobacco products, making them potentially carcinogenic. The study found double-strand DNA breaks in human lung cells exposed to smoke from 'safe' cigarettes.
A new study suggests that medical liability concerns may be driving doctors to overprescribe antibiotics in healthcare settings. The research found a strong correlation between antibiotic use and attorney density in European countries, but no such link with physician density.
Research links BRCA1 gene mutations to lower ovarian response rates in women undergoing fertility preservation treatments for breast cancer. Women carrying the mutated gene are more likely to experience infertility due to decreased egg production.
A study suggests that obese women should not aim to gain excessive weight during pregnancy, challenging previous guidelines. Instead, a well-balanced and nutritionally monitored program can provide better health outcomes for both mother and baby.
Researchers at New York Medical College discovered a link between bird lack of brown fat and dinosaur extinction. The study found that birds' inability to generate heat may have contributed to the demise of dinosaurs.
The Newman team won an NSF award for their work on biological self-assembly, a principle that considers the physical properties of cells and tissues to develop new organs. Their research could lead to the 'printing' of replacement parts using organ printing, revolutionizing organ transplantation.
A new study published in Annals of Internal Medicine found that blood stream invasion occurs in nearly half of untreated adults with erythema migrans, a tell-tale bull's eye rash. Younger patients and those with prior Lyme disease experience lower rates of invasion.
Researchers warn that live flavivirus vaccines can recombine, resulting in new microbes with undesirable properties. The use of these vaccines requires international approval due to safety concerns, including increased virulence, disease development in compromised individuals, and birth defects.
Researchers at New York Medical College are exploring bacterial antibiotic resistance in salmon aquaculture and developing new diagnostic tests for Lyme disease. The studies aim to improve understanding of the diseases and test new methods for prevention and control.
Researchers have found that adult rat hearts contain cardiac progenitor cells capable of repairing damaged tissue. The study, published in Cell, used these cells to regenerate new myocytes and other functional cells in ischemic hearts.
New research adds to evidence that acetaminophen may prevent colon cancer in lab animals. The study found that pretreating animals with acetaminophen significantly protected them against cellular changes indicative of colon cancer. However, more animal research is needed before humans can be studied in clinical trials.
