New insight into the way an embryonic retina cell develops

The discovery provides a new vantage point for understanding how a healthy visual system develops. It also raises the possibility of re-directing the production of cell types as needed to stave off eye disease.

Zoloft may prevent recurrence of depression in patients with diabetes

A team of researchers at Washington University School of Medicine in St. Louis found that an antidepressant medication may reduce the risk of recurrent depression and increase the length of time between depressive episodes in patients with diabetes.

MicroCT-based virtual histology

Utah and Texas researchers combined miniature medical CT scans with high-tech computer methods to produce detailed three-dimensional images of mouse embryos - an efficient new method to test the safety of medicines and learn how mutant genes cause birth defects or cancer.

Mutated gene leads to JSRD

The research team, directed by Joseph Gleeson, M.D., Director of the Neurogenetics Laboratory at the UCSD School of Medicine and associate professor in the Department of Neurosciences, have identified a new gene that, when mutated, leads to JSRD. Their findings will be published on-line in advance of publication in the journal Nature Genetics.

Bladeless LASIK as good as standard microkeratome LASIK

A Mayo Clinic study comparing femtosecond (bladeless) and mechanical microkeratome LASIK surgeries has found equal results from both types six months post-surgery, using a variety of vision and eye health measurements.

Obtaining and documenting informed patient consent prior to surgery

Obtaining and documenting informed patient consent prior to surgery is of vital importance, but both the process and documentation of consent can be inadequate.

Compensation by tumor suppressor genes during retinal development in mice and humans

Humans are more susceptible to developing the eye cancer retinoblastoma than mice because, unlike humans, mice can compensate for the loss of activity of a gene critical to normal retinal development, according to results of a study by investigators at St. Jude Children's Research Hospital.

The 30-year natural history of type 1 diabetes complications

...while cases of premature death and a few other complications have declined, rates of other serious diabetes-related disorders such as heart and eye disease have not improved over the past 25 to 30 years.

New theory on how the brain detects motion

Researchers at the Salk Institute for Biological Studies have discovered a neural circuit that is likely to play an important role in the visual perception of moving objects. Their finding, published in the April issue of the journal Neuron, forces neurobiologists to rethink the neural pathways that our brain relies on to detect motion.

Prenatal exposure to alcohol can change child's circadian rhythms

Altered sleeping and eating patterns, behavioral problems, attention deficits and depression in children with fetal alcohol spectrum disorders may indicate that their biological rhythms, which are controlled by circadian systems, have been affected by alcohol exposure during development.

New method allows heart beat triggers to be viewed and better understood

Researchers have developed unique chemical dyes that have made it possible to see what the naked eye has never seen before: action potentials, or voltage changes, of cardiac cells - including those deep inside the heart, which trigger and determine the pace of heartbeats.

Patching for corneal abrasion

Simple corneal abrasions do not need to be treated by patching the eye, according to a new review of studies that found patching initially slows healing and does not reduce pain.

$Photorefractive keratectomy (PRK) versus laser-assisted in-situ keratomileusis (LASIK) for myopia$

Photorefractive keratectomy (PRK) versus laser-assisted in-situ keratomileusis (LASIK) for myopia

A new review of recent studies suggests two popular laser-assisted surgeries to correct nearsightedness are equally effective at restoring 20/20 vision six months to a year after the surgery.

One melanoma means there's a 15% risk of another

According to researchers in the U.S. recurrent melanoma is more common than previously thought, and as many as 15 percent of people diagnosed with the potentially fatal skin cancer are at risk of a second diagnosis within two years.

Approval of integrated insulin pump and continuous glucose system a significant step towards artificial pancreas technology

The Juvenile Diabetes Research Foundation (JDRF) has said that the federal government's approval of an insulin pump that also provides real-time, continuous glucose monitoring is a significant step on the path to the development of an artificial pancreas, with the potential to significantly improve diabetes care and lower the risk of complications.
