Researchers reverse juvenile diabetes in animal model

...diabetes is higher than virtually all other severe chronic diseases of childhood. Peak incidence occurs during puberty, around 10 to 12 years of age in girls, and around 12 to 14 years of age in boys. The symptoms of type 1 diabetes can resemble the flu in children. Type 1 diabetes tends to run in familie...

New drug could reduce tissue damage after heart attack

... diseases including trauma, infection, strokes and chronic illnesses such as rheumatoid arthritis and Crohn's disease. CRP levels also rise dramatically after a heart attack. Patients with the greatest and most persistent increases in CRP concentration suffer higher mortality, and CRP is always deposited i...

The annual consumption in Spain is about 10 tons but, at a worldwide level, the demand exceeds 500 tons. Agricultural engineer, Alicia Fernández San Millán, has developed a novel technique in Spain - plastidi...

Dr Paul Thomas from the University's School of Chemical Engineering and Analytical Science, who is leading the research, said: "Our vision is that one day we will be able to detect a previously undete...

Marine mammals are on the frontline of failing ocean health

...eptible to new diseases. "The insidious effect of chronic exposure is what worries me the most," says Bossart. "This infers that you could really open a Pandora's box in these animals, and possibly in humans. Manatees are the 2000 pound canary." Bossart is also concerned about new data indicating that fi...

Concern over fast tracking of new drugs

...and safety is lacking. Short term solutions for a chronic disease like multiple sclerosis are not likely to be effective, and experience with natalizumab should be taken as a signal to change the way we treat this disease, he concludes. ...

Study by Einstein researchers could lead to a novel strategy for treating obesity

... the hypothalamus of rats. The injections caused a chronic decrease in malonyl CoA levels, which dramatically increased the rats' food intake and led to obesity that was maintained for at least four months. "We showed in this study that disrupting malonyl-CoA levels in this region of the brain impairs the n...

Brain differences could explain why males and females experience pain relief differently

...lgia are the most prevalent and pervasive forms of chronic pain. Clinical evidence suggests that women are much more likely to experience chronic forms of pain than are men and that women report feeling more pain than men following various medica...

MiRNA fingerprint identified in platelet formation

Platelets are created from stem cells in the bone marrow. They evolve through a process called megakaryocytopoiesis, which gene...

"I don't think there's a neuromuscular junction that hasn't been inhibited by injecting with botox A," says Chapman. Chapman and his team located the exact molecular gateway through which botox penetrates cells by g...

Two NIH initiatives launch intensive efforts to find roots of common diseases

...e do not tell the whole story. Recent increases in chronic diseases like diabetes, childhood asthma, obesity or autism cannot be due to major shifts in the human gene pool. They must be due to changes in the environment, including diet and physical activity, which may produce disease in genetically predispos...

Mice lacking social memory molecule take bullying in stride

The results suggest that chronic treatment with antidepressants restores social approach behaviors partly by interfering with the cascade of activity triggered by BDNF as the organism adapts to experience. The researchers say the study "suggests new directions for antidepressant ...

Scientists discover a new disease-causing bacterium in an immune-compromised patient

...The new bacterium was identified in a patient with chronic granulomatous disease (CGD), a rare genetic disorder that impairs the immune system. In the patient, the bacterium caused fever, lymph node inflammation, and weight loss, but not death. The journal also published an editorial entitled, "Extendin...
