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.

Improving diet quality reduces risk for type 2 diabetes

Posted: 14 Jun 2014 12:03 PM PDT

Improving the overall quality of one's diet helps to prevent type 2 diabetes, independent of other lifestyle changes, according to a new study. The study found that those who improved their diet quality index scores by 10 percent over four years -- by eating more whole grains, fruits and vegetables, and less sweetened beverages and saturated fats, for example -- reduced their risk for type 2 diabetes by about 20 percent, compared to those who made no changes to their diets.

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.

Text messages helpful in controlling diabetes

A text message-based self-management intervention improves glycemic control in high risk Latinos with type 2 diabetes, a study shows. The messages in the study focused on healthy nutrition tips, the benefits of physical activity and medication adherence, and requests to check blood sugar and send back results. Two to three messages were sent each day at the beginning of study enrollment, and the frequency tapered off over a six-month period.

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.

Endangered species baby boom at zoo

Posted: 13 Jun 2014 01:16 PM PDT

The Smithsonian's National Zoo and Conservation Biology Institute celebrated several births recently. During the past several weeks, 31 new residents have been born, many of which were endangered species. A short-eared elephant shrew was born May 8 at the Zoo's Small Mammal House. A red panda gave birth to two surviving cubs May 27 at SCBI. This species is vulnerable because of habitat loss. Red pandas live in the cool temperate bamboo forests in parts of China, Nepal and northern Myanmar. There are fewer than 10,000 adult red pandas left in the wild.

Nurses play critical role in responding to global resurgence of pertussis

Posted: 13 Jun 2014 10:04 AM PDT

Pertussis (whooping cough) is on the increase in the United States and around the world -— and nurses play an essential role in educating parents and patients about the safety and effectiveness of pertussis vaccination, according to a new paper. Caused by infection with Bordetella pertussis bacteria, pertussis has been increasing in recent years. Worldwide, there are an estimated 50 million cases of pertussis and 300,000 deaths. Pertussis is a major cause of death in infants worldwide.

Testing Parkinson's disease immune-based drugs: New models

Posted: 12 Jun 2014 10:23 AM PDT

Using powerful, newly developed cell culture and mouse models of sporadic Parkinson's disease (PD), researchers have demonstrated that immunotherapy with specifically targeted antibodies may block the development and spread of PD pathology in the brain. By intercepting the distorted and misfolded alpha-synuclein (α-syn) proteins that enter and propagate in neurons, creating aggregates, the researchers prevented the development of pathology and also reversed some of the effects of already-existing disease.

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.
