| Tales from the crypt: Study on gut cell regeneration reconciles long-standing research controversy Posted: 11 Nov 2011 12:22 PM PST The cells that help to absorb food and liquid that humans consume are constantly being produced. The various cell types that do this come from stem cells that reside deep in the inner recesses of the accordion-like folds of the intestines, called villi and crypts. But exactly where the most important stem cell type is located -- and how to identify it -- has been something of a mystery, until now. |
| Researchers closer to the super bug puzzle Posted: 11 Nov 2011 06:55 AM PST The treatment of serious infections caused by Staphylococcus aureus (Golden Staph) is complicated by the development of antibiotic resistance. Seriously ill patients, vulnerable to infections can be at additional risk if antimicrobial agents become less effective in fighting infections. |
| Study suggests new benefits of eating nuts for patients with metabolic syndrome Posted: 11 Nov 2011 06:52 AM PST A recent scientific study has revealed the relationship between nut consumption and a high level of serotonin metabolites (an important neurotransmitter) in patients with metabolic syndrome, who are at high risk of cardiovascular disease. |
| Diseased hearts to heal themselves in future Posted: 11 Nov 2011 06:52 AM PST Oncostatin M regulates the reversion of heart muscle cells into precursor cells and is vitally important for the self-healing powers of the heart. Scientists have identified a protein which fulfils a central task in this reversion process by stimulating the regression of individual heart muscle cells into their precursor cells. They now plan to improve the self-healing powers of the heart with the help of this protein. |
| Eating fish can reduce the risk of diabetes Posted: 11 Nov 2011 06:51 AM PST A study analyses the dietary patterns of the adult Spanish population with high cardiovascular risk. The results reveal a high consumption of both red meat and fish. However, whilst eating lots of cured meats is associated with greater weight gain and a higher obesity rate, the consumption of fish is linked to lower glucose concentrations and a smaller risk of developing diabetes. |
| Gene switch for odorant receptors Posted: 11 Nov 2011 06:51 AM PST The olfactory sensory neurons in the nasal mucosa perceive the myriad smells in the air with the aid of odorant receptors. Each sensory neuron chooses one and only one receptor gene for expression. The probability that a particular receptor gene is chosen for expression determines how many olfactory sensory neurons in total produce this receptor type. Scientists have unveiled an aspect of how the probability of the choice of an odorant receptor gene is regulated in olfactory sensory neurons. |
| Birth weight predicts physical functioning at age 60 Posted: 11 Nov 2011 06:45 AM PST Low birth weight and slow growth progressing to greater body mass in pre-adolescence significantly increased the risk of poor physical functioning at the age of 60 years, a new Finnish study found. |
