Contrary to popular belief among physicians, frailty in elderly patients is not associated with an increased risk of adverse reactions to medications, according to a study led by Michael Steinman, MD, a geriatrician at the San Francisco VA Medical Center. The study of 377 patients age 65 or older appears in the online Early View section of the Journal of the American Geriatrics Society. "There is a common, and reasonable, perception among clinicians that older people who are unable to carry out activities of daily living such as bathing, dressing, and walking without ...

Jimmy Fallon, the host of "Late Night With Jimmy Fallon" has carved out his own little corner of the late night universe, appealing to a particular brand of pop culture awareness and nostalgia. That love of junk culture from a particular era (mostly the early '90s) inspired Fallon to stage reunions of the casts of "Saved By the Bell" and "California Dreams" as well as a number of music acts from the era. Such was the case when Bel Biv Devoe took the stage at 30 Rock to tear into their classic single "Poison." BBD is represented for celebrity appearances by none other than ...

Two new UC Davis studies add scientific evidence that hunters' lead ammunition often finds its way into carrion-eating birds, such as eagles and turkey vultures. These scavenger species often take advantage of animal remains left behind when a hunter cleans a kill or when a shot deer or wild pig escapes the hunter but dies later. However, when the remains contain lead shot pellets or bullet fragments, the scavenger birds can develop lead poisoning, which can cause inability to fly, starvation, anemia, blindness, seizures and death. In 1991, to protect bald eagles, ...

Cave fish sleep significantly less than their surface counterparts, a finding by New York University biologists that reveals the genes involved in sleep patterns and disorders. Their study, which appears in the journal Current Biology, may shed light on how genetic makeup contributes to sleep variation and disruption in humans. The study's authors were Erik Duboué, an NYU graduate student, Alex Keene, an NYU post-doctoral fellow, and Richard Borowsky, a professor in NYU's Department of Biology. They examined surface fish in the species Astyanax mexicanus and three cave ...

In just six years, bacteria in the genus Rickettsia spread through a population of the sweet potato whitefly (Bemisia tabaci), an invasive pest of global importance. Infected insects lay more eggs, develop faster and are more likely to survive to adulthood compared to their uninfected peers. The discoveries were made by a University of Arizona-led team of scientists and are published in the April 8 issue of the journal Science. "It's instant evolution," said Molly Hunter, a professor of entomology in the UA's College of Agriculture and Life Sciences and the study's ...

Researchers at Northwestern University have developed a model that will allow them to simulate how rats use their whiskers to sense objects around them. The model enables further research that may provide insight into the human sense of touch. Hundreds of papers are published each year that use the rat whisker system as a model to understand brain development and neural processing. Rats move their whiskers rhythmically against objects to explore the environment by touch. Using only tactile information from its whiskers, a rat can determine all of an object's spatial ...

A new study demonstrates that a procedure used in preconception diagnosis to identify eggs that are free of genetic disease might not work well in all cases. The research, published by Cell Press in the April issue of the American Journal of Human Genetics, highlights the issues associated with analyzing the amount of mutant mitochondrial DNA in supporting cells as a proxy for eggs prior to in vitro fertilization. Preimplantation genetic diagnosis (PGD) and preconception diagnosis (PCD) are services that have been very useful to couples who have a genetic defect in their ...

The American Association for the Advancement of Science has launched an innovative website to help educators assess more precisely what students know about key ideas in science and -- just as importantly -- the incorrect ideas they have. It offers an unusually detailed picture of how middle and high school students across the United States are currently doing in science, and features information on what they know and on hundreds of misconceptions they have about everything from the size of atoms to whether all organisms have DNA. Knowing these misconceptions and how ...

The internally-driven daily cycle of blood pressure changes doesn't appear to be linked to the known increase in morning heart attacks, according to a study in Circulation Research: Journal of the American Heart Association. Researchers sought to identify the role of the internal human body clock in the daily rise and fall in blood pressure. In the study, three groups of volunteers showed an internal daily blood pressure variation with a peak at around 9 p.m. — independent of changes in activity and other behavioral influences that can affect blood pressure. Increased ...

Virtual reality (VR) and other video games led to significant improvement in arm strength following stroke and could provide an affordable, enjoyable and effective way to intensify treatment, according research reported in Stroke: Journal of the American Heart Association. Researchers analyzed seven observational and five randomized trials, representing a total of 195 patients, ages 26 to 88, who had suffered mild to moderate strokes. Each study had investigated the effects of electronic games on upper arm strength and function. In the observational studies, there ...

David Blair of QuadCap Wealth Management, LLC, recently spoke to a group of Dallas business owners regarding the necessity of withholding and/or estimated payments. An excerpt of this talk follows: "The United States tax system is a pay-as-you-go system that requires taxpayers to pay as the income they are taxed on is earned. If you are paying your taxes throughout the year through withholding, you can increase this towards the end of the year to make up any shortfall. If you are self-employed however, you must make estimate payments throughout the year." The first ...

SEATTLE—A video-based decision aid helped severely obese people to make more informed choices about bariatric surgery and reach more certainty about them, according to a trial involving 152 Group Health patients, e-published in Obesity in advance of print. This randomized controlled trial is the first to test shared decision making for weight-loss surgery. Researchers randomly assigned half the patients to receive an educational booklet on bariatric surgery and half to watch the video-based decision aid. After three months, those who watched the video felt less conflicted ...

STANFORD, Calif. — People who use in vitro fertilization to conceive children often have leftover embryos and must decide whether to store them, dispose of them or possibly donate them for research. A new process developed by researchers at the Stanford University School of Medicine allows these people to make this decision in the privacy of their own homes — without any interaction with clinic personnel or scientists who might benefit from the research. "There is concern that conflicts of interest and influence by researchers and clinicians may play a role in donor choice," ...

A paper published by Cell Press in the April 8th issue of the journal Cell Stem Cell reveals a new and more efficient method for reprogramming adult mouse and human cells into an embryonic stem cell-like state and could lead to better strategies for developing stem cells for therapeutic use. The ability to reprogram adult cells into cells that resemble embryonic stem cells has tremendous potential for both stem cell research and regenerative medicine. "Previous studies have demonstrated the usefulness of iPSCs not only in the study of basic stem biology, but also in ...

PHILADELPHIA - Researchers at the University of Pennsylvania School of Medicine have devised a totally new and far more efficient way of generating induced pluripotent stem cells (iPSCs), immature cells that are able to develop into several different types of cells or tissues in the body. The researchers used fibroblast cells, which are easily obtained from skin biopsies, and could be used to generate patient-specific iPSCs for drug screening and tissue regeneration. iPSCs are typically generated from adult non-reproductive cells by expressing four different genes called ...

These nonsurgical procedures meet the demands of patients' busy schedules while helping them look their best and allowing them to remain on-the-go. "My Los Angeles plastic surgery patients choose from a wide range of procedures," says Dr. Stevens, "and ...

We all know that people at opposite ends of the political spectrum often really can't see eye to eye. Now, a new report published online on April 7th in Current Biology, a Cell Press publication, reveals that those differences in political orientation are tied to differences in the very structures of our brains. Individuals who call themselves liberal tend to have larger anterior cingulate cortexes, while those who call themselves conservative have larger amygdalas. Based on what is known about the functions of those two brain regions, the structural differences are consistent ...

Cave life is known to favor the evolution of a variety of traits, including blindness and loss of eyes, loss of pigmentation, and changes in metabolism and feeding behavior. Now researchers reporting online on April 7 in Current Biology, a Cell Press publication, have added sleeplessness to that list. "Cave-adapted fish sleep less—much less—than closely related surface fish," said Richard Borowsky of New York University. "In some ways, their sleep phenotypes are similar to those of humans with sleep disorders." The fish do sleep, but only for relatively short periods, ...
