Reversal of type 1 diabetes in mice may eventually help humans

Posted: 14 Jun 2014 04:26 PM PDT

Investigators have found a therapy that reverses new onset type 1 diabetes in mouse models and may advance efforts in combating the disease among humans. There is no cure for Type 1 diabetes though it can be controlled with insulin therapy. Symptoms of the disease include frequent urination, excessive thirst and weight loss even though you are eating more.

Canola oil may be an oil of choice for people with type 2 diabetes

Posted: 14 Jun 2014 12:03 PM PDT

New research suggests canola oil may be one of the oils of choice for people with Type 2 diabetes. Researchers compared people with Type 2 diabetes who ate either a low glycemic index diet that included bread made with canola oil, or a whole wheat diet known to reduce the risk of cardiovascular disease. The research found that those on the canola bread diet experienced both a reduction in blood glucose levels and a significant reduction in LDL, or "bad," cholesterol.

Fasting reduces cholesterol levels in prediabetic people over extended period of time, new research finds

Posted: 14 Jun 2014 12:01 PM PDT

For prediabetics, many interventions focus on lifestyle changes and weight loss, but new research on periodic fasting has identified a biological process in the body that converts bad cholesterol in fat cells to energy, thus combating diabetes risk factors.

Plate tectonics: Studies show movements of continents speeding up after slow 'middle age'

Posted: 13 Jun 2014 07:51 PM PDT

Two studies show that the movement rate of plates carrying the Earth's crust may not be constant over time. This could provide a new explanation for the patterns observed in the speed of evolution and has implications for the interpretation of climate models.

Gender differences in obesity-related mortality revealed

Posted: 13 Jun 2014 07:51 PM PDT

Obesity, which affects more than one-third of Americans, is a chronic disease that can shorten one's life span, but new findings show that its effect on mortality has reduced in recent years among many groups, particularly women. "One of the possibilities our findings suggest, but do not prove, is that advances in medicine, screening procedures and interventions may have reduced the excess mortality associated with Grade 1 obesity; there are yet other explanations, as well," said one researcher.

Scientists find trigger to decode the genome

Posted: 12 Jun 2014 09:13 AM PDT

An important trigger that dictates how cells change their identity and gain specialized functions has been decoded by scientists. The scientists have found out how embryonic stem cell fate is controlled which will lead to future research into how cells can be artificially manipulated. "We believe that our research will help to make regenerative medicine more effective and reliable because we'll be able to gain control and manipulate cells -- thus our understanding of the regulatory events within a cell shed light on how to decode the genome," concluded the lead author.

Fungal protein found to cross blood-brain barrier

Posted: 12 Jun 2014 07:49 AM PDT

In a remarkable series of experiments on a fungus that causes cryptococcal meningitis, a deadly infection of the membranes that cover the spinal cord and brain, investigators have isolated a protein that appears to be responsible for the fungus' ability to cross from the bloodstream into the brain.

Proliferation cues 'natural killer' cells for job change

Posted: 12 Jun 2014 06:52 AM PDT

Why would already abundant 'natural killer' cells proliferate even further after subduing an infection? It's been a biological mystery for 30 years. But now scientists have an answer: After proliferation, the cells switch from marshaling the immune response to calming it down. The findings illuminate the functions of a critical immune system cell important for early defense against disease induced by viral infection.

Antibodies from desert as guides to diseased cells

Posted: 12 Jun 2014 06:52 AM PDT

Nanoparticles are considered a promising approach in detecting and fighting tumor cells. The method has, however, often failed because the human immune system recognizes and rejects them before they can fulfill their function. Researchers have developed nanoparticles that bypass the body's defense system and find the diseased cells. This procedure uses fragments from an antibody that only occurs in camels and llamas.

New obesity drug closer than ever

Posted: 12 Jun 2014 06:51 AM PDT

Obesity and diabetes are among the fastest growing health problems in the world, and the hunt is in for a pill that can fight the problem. Now a research team has come up with a smart tool that will speed up the scientific hunting process, and we may be one step closer to a pill against obesity.
