Fast vibrational analysis of molecular systems.

The development of infrared difference spectroscopy provides unprecedented insights on structures of complex molecules like metalloproteins. However, the relevant information can be hard to find among the many bands of the vibrational spectra. The ab initio modeling is very helpful to assign the frequencies to vibrational modes but it is a challenge to process the huge quantity of data into descriptors useful for experimentalists.

Parvalbumin gates chronic pain through the modulation of firing patterns in inhibitory neurons.

Spinal cord dorsal horn inhibition is critical to the processing of sensory inputs, and its impairment leads to mechanical allodynia. How this decreased inhibition occurs and whether its restoration alleviates allodynic pain are poorly understood. Here, we show that a critical step in the loss of inhibitory tone is the change in the firing pattern of inhibitory parvalbumin (PV)-expressing neurons (PVNs).

[Secondary prevention of cardiovascular diseases : targeting all the cardiovascular risk factors].

This article focuses on the secondary prevention of cardiovascular (CV) diseases, namely the prevention of recurrence in subjects with a personal history of CV event, and the prevention of a first event in patients identified as at very high risk. For all these patients at very high risk, treatment is primarily based on the application of hygienic and dietary measures, including increasing the volume of physical activity, modifying the diet, and obtaining, if necessary, weight loss, as well as stopping smoking. This strategy has proven its benefits in terms of reducing morbidity and mortality.
