Hospital Disaster Potential Highighted By Swedish Study
Factors that lead to emergency department overcrowdings, ambulance diversions and other incidents that endanger patient safety have been revealed. A study published in BioMed Central"s open access Scandinavian Journal of Trauma, Resuscitation and Emergency Medicine has shown that reductions in the number of hospital beds and downsizing or closure of emergency departments may create a dangerous loss of "surge capacity".

Moist Wound Healing Reduces Scarring And Promotes Faster Healing
New consensus has been reached by a panel of leading European experts on the guidelines for the treatment of acute minor wounds which states that healing is accelerated by a moist wound environment.

How Mitochondria Get Their Membranes Bent
Mitochondria are the powerhouses of cells. Underneath their smooth surface they harbor an elaborately folded inner membrane. It holds a multitude of bottleneck like invaginations, which expand into elongated cavities (cristae). The narrow shape of the entrance or pore to the cristae ("crista junction") allows separation of the intracristal space and storage of molecules. Cytochrome c, for example, an important signaling protein in programmed cell death (apoptosis), is stored in this compartment. When apoptosis is triggered, the pores enlarge and cytochrome c is released into the cytosol. Thus, understanding of how the pore diameter and the shape of the inner membrane are regulated on a molecular basis is of great relevance to a better understanding of mitochondrial function in general. Recently, in cooperation with other research teams, the group of Prof. Andreas Reichert, who has been appointed as professor for Mitochondrial Biology to the Goethe University within the Cluster of Excellence Macromolecular Complexes in 2007, has identified two proteins linked in an antagonistic manner that are relevant for governing inner membrane structure.

Allergy Season: Cigarettes To The Rescue?

Everyone knows that smoking can kill you, but did you know that it may help with your allergies? A new study shows that cigarette smoke can prevent allergies by decreasing the reaction of immune cells to allergens. Smoking can cause lung cancer, pulmonary disease, and can even affect how the body fights infections. Along with many harmful effects, smoking cigarettes has a surprising benefit: cigarettes can protect smokers from certain types of allergies. Now, a study recommended by Neil Thomson, a member of Faculty of 1000 Biology and leading expert in the field of respiratory medicine, demonstrates that cigarette smoke decreases the allergic response by inhibiting the activity of mast cells, the major players in the immune system"s response to allergens. Researchers at Utrecht University in the Netherlands found that treatment of mast cells with a cigarette smoke-infused solution prevented the release of inflammation-inducing proteins in response to allergens, without affecting other mast cell immune functions. The mast cells used in the study were derived from mice, but it is likely that the same anti-allergy effect will hold true in humans. While taking up smoking to cure allergies is unwise, Thomson concludes that the findings presented in this study are "consistent with a dampening of allergic responses in smokers."
