Congenital TTP is characterized by blood clots in small blood vessels throughout the body. If untreated, people with TTP can develop strokes, heart attacks, or kidney damage. Today, the most common therapy for TTP consists of plasma infusions, in which individuals with severe cases of the disease must go to a hospital to receive the blood product from a donor to replenish the missing enzyme in the blood. However, many patients become intolerant to plasma. They develop severe allergic reactions, which make it nearly impossible to treat them. If they can receive treatment, it's under very close supervision and with precautions. "Today, TTP patients are under-treated because of the complications associated with blood plasma infusions, which has remained the standard treatment for at least half a century," said senior study author Bruce Ewenstein, MD, PhD, of Shire in Cambridge, MA. "Plasma as a source of enzyme replacement is a sledgehammer approach to treatment, bu...

Pores and skin TRM (seen in crimson) 'sense' infections and 'alarm' host tissue to recruit effector cells (inexperienced) to the pores and skin the place they contribute to viral clearance. Regardless of upkeep of pores and skin TRM in septic hosts (CLP), tissue-wide recruitment of effector cells was drastically diminished leading to enhanced susceptibility to secondary pores and skin infections. Website-specific administration of chemokines (CXCL9-10) restored homing indicators that had been diminished in septic hosts to allow recruitment of effector cells to the pores and skin. Thus, this method may show helpful to boost the septic affected person's T-cell-mediated immunity throughout the interval of immunosuppression.

Now researchers at Duke Cancer Institute have not only untangled an unusual wiring system that cancer cells use for carbohydrate metabolism, but also identified a natural compound that appears to selectively shut down this system in laboratory studies. "The Warburg Effect has been known for decades, but the underlying mechanisms are not well understood," said Jason Locasale, assistant professor in the Department of Pharmacology & Cancer Biology at Duke and senior author of a study published Sept. 14 in the journal  Cell Metabolism . "We started with the idea that if you understand how it works, you should be better able to control it, and we think we might have some insight on that, as well." Locasale and colleagues, including lead author Maria Liberti, studied cancer cells to determine how their metabolism changes so dramatically from that of normal cells, which use oxygen to break down sugar. Cancer cells, instead, use fermentation, which is less efficie...

"Numerous sweeteners exhibit undesirable off-tastes, limiting their use in food products and beverages," says lead author Maik Behrens of the German Institute of Human Nutrition Potsdam-Rehbruecke. "Our findings in this study provide us with the tools and knowledge to find ways leading to superior sweetener blends." High-potency sweeteners are widely used to replace energy-rich, tooth-decay-inducing sugars in food items to meet the requirements of health-conscious consumers. But in addition to stimulating sweet taste receptors, sugar substitutes also activate bitter taste receptors (known as TAS2Rs) at high concentrations, resulting in an undesired off-taste. To overcome this problem, the food industry is constantly searching for novel sugar substitutes and frequently resorts to using blends combining non-caloric sweeteners in a single formulation. The earliest blend allowing higher sweetness levels with reduced bitter off-taste combined saccharin with cyclama...

For many students, college involves a lot of socializing at parties and at bars, and alcohol is a common factor in these social environments. Excessive alcohol use, in the form of binge drinking, is extremely common among college students, and one study has estimated that as many as one third of young North Americans and Europeans binge drink. So, what defines binge drinking? The National Institute of Alcohol Abuse and Alcoholism describes a binge as drinking five or more drinks for men and four or more for women within a two-hour period, and for many college students, these limits wouldn't equate to a particularly heavy night. Previous research has linked binge drinking to a variety of negative consequences including neurocognitive deficits, poor academic performance, and risky sexual behavior. While numerous studies have shown that the brains of chronic alcoholics have altered brain activity, there is also evidence that bingeing can change adolescents' brains. Eduardo ...
