Lack of very long chain fatty acids does not cause blindness in children with Stargardt type 3

Vision scientists long have thought that lack of very long chain fatty acids in photoreceptor cells caused blindness in children with Stargardt type 3 retinal degeneration, an incurable eye disease. But researchers at the University of Utah's John A. Moran Eye Center have shown in a new study that lack of these fatty acids does not cause blindness, meaning that the search for the mechanism that robs sight from children with the disease must start anew.

UniStem Day 2013 to take place on Mar. 15

This year, six Spanish universities participate in UniStem Day 2013, an event that takes place next Friday, 15th March. It is the first time that the event is carried out simultaneously in several European countries.

Scientists reveal genetic activity that led to development of wings in fruit flies

Scientists have delved deeper into the evolutionary history of the fruit fly than ever before to reveal the genetic activity that led to the development of wings - a key to the insect's ability to survive.

Researchers discover new mechanism that allows collective cell migration

Researchers at the University of Montreal's Institute for Research in Immunology and Cancer (IRIC) have discovered a new mechanism that allows some cells in our body to move together, in some ways like the tortoise formation used by Roman soldiers depicted in the Asterix series.

Study: No increase in mortality with well-controlled HIV

For HIV-infected patients whose disease is well-controlled by modern treatment, the risk of death is not significantly higher than in the general population, according to a study published in AIDS, official journal of the International AIDS Society. AIDS is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health.

Cell phone microscope can detect intestinal worm infections in children

Scientists working in rural Tanzania have used a simple US$8 glass lens, a strip of double-sided tape, and a cheap flashlight to convert an Apple iPhone into a field microscope that can successfully detect intestinal worm infections in children, according to a study published online today by the American Journal of Tropical Medicine and Hygiene.

MiR-198 controls migration of skin cells necessary for wounds to close and heal

Patients with diseases such as diabetes suffer from painful wounds that take a long time to heal making them more susceptible to infections that could even lead to amputations. A*STAR's discovery paves the way for therapeutics to improve healing of such chronic wounds, which are a significant burden to patients.

Researchers develop new approach to screening potential treatments for Alzheimer's disease

According to a 2012 World Health Organization report, over 35 million people worldwide currently have dementia, a number that is expected to double by 2030 (66 million) and triple by 2050 (115 million).

Transfusion of older blood adversely affects patients undergoing cardiac surgery or critical care

Transfusion of donated blood more than three weeks old results in impaired blood vessel function, a new study of hospital patients shows.

Researchers identify new mechanism in onset of motor neuron diseases

The British astrophysicist Stephen Hawking is likely to be the world's most famous person living with amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease. ALS is a progressive disease affecting motor neurons, nerve cells that control muscle function, and nearly always leads to death.

Influenza drug: an interview with Dr Jenny McKimm-Breschkin, CSIRO

Influenza or flu for short is caused by a family of viruses, which can be called influenza A or influenza B. Influenza A viruses are found in humans, animals – like swine and horses- and mostly aquatic birds. Influenza B is only found in humans.

SDF-1 turns on autophagy that helps cells stay in place and focused on making bone

A signaling molecule that helps stem cells survive in the naturally low-oxygen environment inside the bone marrow may hold clues to helping the cells survive when the going gets worse with age and disease, researchers report.

New immunoassay appears to be valid screening method for early detection of renal cell carcinoma

A new immunoassay that tests for the presence of three biomarkers appears to be a valid screening method for the early detection of malignant kidney cancer, according to data published in Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research.

Genetic mutation that alters PIEZO1 ion channel in RBCs contributes to familial xerocytosis

A genetic mutation that alters the kinetics of an ion channel in red blood cells has been identified as the cause behind a hereditary anemia, according to a paper published this month in the Proceedings of the National Academy of Sciences by University at Buffalo scientists and colleagues.

Combining mitochondrial inhibitors could improve efficacy of BRAF inhibitors in melanoma

A multi-institutional study has revealed that BRAF-positive metastatic malignant melanomas develop resistance to treatment with drugs targeting the BRAF/MEK growth pathway through a major change in metabolism.

Planar cell polarity genes control connectivity of enteric neurons

The enteric nervous system (ENS), the "little brain" that resides within the gut wall, governs motility, secretion, and blood flow in the human gastrointestinal tract. Failure of the ENS to develop normally leads to congenital megacolon (Hirschsprung Disease) while loss of normal gut innervation is thought to contribute to debilitating motility disorders, such as irritable bowel syndrome.

Cell fusion studies at Johns Hopkins could lead to improved treatments for muscular dystrophy

Researchers at Johns Hopkins have established a high-efficiency cell-cell fusion system, providing a new model to study how fusion works. The scientists showed that fusion between two cells is not equal and mutual as some assumed, but, rather, is initiated and driven by one of the fusion partners. The discovery, they say, could lead to improved treatments for muscular dystrophy, since muscle regeneration relies on cell fusion to make muscle fibers that contain hundreds or even thousands of nuclei.

AKAP protein alterations implicated in bipolar disorder

Researchers have found increased cellular expression of the postsynaptic signaling protein AKAP5/79 in the anterior cingulate cortex of patients with bipolar disorder.
