Scientists Discover a Better Way to Make Unnatural Amino Acids

Posted:

At The Scripps Research Institute (TSRI), chemists have devised a greatly improved technique for making amino acids not found in nature. These "unnatural" amino acids traditionally have been very difficult to synthesize, but are sought after by the pharmaceutical industry for their potential medical uses. "This new technique offers a very quick way to prepare unnatural amino acids, many of which are drug candidates or building blocks for peptide drugs," ...

Forgetting is Actively Regulated in Our Brain

Posted:

The human brain requires the ability not only to store but also to forget in order to function properly: Through memory loss, unnecessary information is deleted and the nervous system retains its plasticity. A disruption of this process can lead to serious mental disorders. Basel scientists have now discovered a molecular mechanism that actively regulates the process of forgetting. The renowned scientific journal "iCell/i" has published their results. The ...

Water may Not Aid Weight Loss

Posted:

There is no enough evidence that shows drinking lots of water will aid in weight loss, says a researcher. Beth Kitchin, Ph.D., R.D., assistant professor of nutrition sciences, said that there is very little evidence that drinking water promotes weight loss; it is one of those self-perpetuating myths. Kitchin said that another water myth is the consumption rule: eight 8-ounce glasses of water per day. A final water myth Kitchin wants ...

A beneficial fungal yeast iPichia/i could actually prevent the growth of iCandida/i, a new study has recently found. i Candida/i is the culprit in oral candidiasis, a painful mouth infection known as thrush. The hope for this finding is that components in iPichia/i could one day become therapeutic agents to stave off not only thrush, but also other life-threatening systemic fungal infections. Research findings about the effect of oral iPichia/i on iCandida/i ...

Scientists Find New Way to Save Brain Cells After Stroke

Posted:

A major reduction in disability after a stroke has been observed after using a compound to block the body's immune response. The study by scientists from the University of Wisconsin School of Medicine and Public Health also showed that particular immune cells - CD4+ T-cells produce a mediator, called interleukin (IL) -21 that can cause further damage in stroke tissue. Moreover, normal mice, ordinarily killed or disabled by an ischemic stroke, were given a shot of ...

New Reversible Mechanism to Increase Muscle Elasticity Discovered

Posted:

How exactly does yoga improve flexibility? In the Mar 13 cover story of iCell/i, Columbia University biological sciences professor Julio Fernandez and team report the discovery of a new form of mechanical memory that adjusts the elasticity of muscles to their history of stretching. Using highly sensitive atomic force microscopes, the researchers detected a chemical reaction that increases the elasticity of muscle proteins. Crucially, this reaction targets molecules ...

Oxygen Deficiency Linked to Brain Damage

Posted:

Lack of oxygen could cause brain damage in conditions like stroke and Alzheimer's disease, a new study found. The discovery, published today in iNeuron/i, brings researchers a step closer to finding potential targets to treat neurodegenerative disorders. Chronic inflammation and hypoxia, or oxygen deficiency, are hallmarks of several brain diseases, but little was known about how they contribute to symptoms such as memory loss. The study ...

Large Waist Could Spell Poor Health, BMI Doesn't Count

Despite a healthy body mass, having a big belly could have detrimental impacts on health. It's detrimental to your health, even if you have a healthy body mass index (BMI), a new international collaborative study led by a Mayo Clinic researcher found. Men and women with large waist circumferences were more likely to die younger, and were more likely to die from illnesses such as heart disease, respiratory problems, and cancer after accounting for body mass index, ...

Nail Biting Could Actually be Fatal!

Nail biting could actually cause septic infection and may even lead to death- John Gardner, a British man, seems to have the same fate. John Gardener had contracted a septic infection because of his habit and died while he was recuperating from a surgery to remove the tip of a finger, Metro.co.uk reported. Gardener's doctor said that the former amateur football referee's fingernails were always in a 'bad condition' and he had lost a lot of sensation ...

Diabetes Ups Pancreatic Cancer Risk

Posted:

A link between diabetes and pancreatic cancer has been discovered by scientists. "The study revealed the risk of pancreatic cancer was greatest after the diagnosis of diabetes but remained elevated long after the diagnosis," said Mehrdad Nikfarjam, liver, pancreas and biliary specialist at the University of Melbourne. "The presence of diabetes remains a modest risk factor for the development of a cancer later in life," he said. A team ...

Cancer Patients With Insulin-Treated Diabetes Have 4 Times Higher Mortality Rate

People who have diabetes at the time they are diagnosed with cancer are more likely to die early than those without diabetes. This was concluded by a research published in iDiabetologia/i (the journal of the European Association for the Study of Diabetes). The research is by Kristina Ranc, University of Copenhagen and Steno Diabetes Center, Gentofte, Denmark, and colleagues. The researchers conclude that patients with both diabetes and cancer constitute a particularly ...

Peripheral Nerve Regeneration Using Fibrin Glue Membrane

Posted:

Following peripheral nerve damage, complete regeneration is usually very difficult, though microsurgical techniques have vastly increased the success rate of surgery to repair the injured nerve. This occurs possibly because of a lack of neurotrophic factors and extracellular matrix in the injured region, which results in a microenvironment that is not optimal for peripheral nerve regeneration. Nerve growth factor (NGF) was the first neurotrophic factor identified ...

Cytotoxicity is a Risk Factor for Diabetic Peripheral Neuropathy

Posted:

Iron overload can lead to cytotoxicity, which in turn is a risk factor for diabetic peripheral neuropathy. However, the underlying mechanism remains unclear. Prof. Shi Zhao and team conjectured that iron overload-induced neurotoxicity might be associated with oxidative stress and the NF-E2-related factor 2 (Nrf2)/ARE signaling pathway. As an in vitro cellular model of diabetic peripheral neuropathy, PC12 cells exposed to high glucose concentration were ...
