The concept of neural plasticity accounts for the now well clarified brain ability to react to internal and external stimuli by transforming its structure and *** translation of whatever experience in specific electrical signals that run through our neural networks induces a number of plastic changes at both functional and structural levels.

Operator-valued frames （or g-frames） are generalizations of frames and fusion frames and have been used in packets encoding, quantum computing, theory of coherent states and more. In this article, we give a new formula for operator-valued frames for finite dimensional Hilbert spaces. As an application, we derive in a simple manner a recent result of A. Najati concerning the approximation of g-frames by Parseval ones. We obtain also some results concerning the best approximation of operator-valued frames by its alternate duals, with optimal estimates.

Dietary phenolic compounds （PCs） have been receiving intercst lor their presumcd roles ill disease prevention. However, there is a lack of studies on the underlying molecular mechanisnls. In this regard, in vitro metabolomic approaches are suitable for the investigation o1 the molecular changes in response to PC exposure. Up to date, the biological effects of PCs have only been cxalnined for PCs from rosemary （Rosmarinus officinalis）, olive oil, and reSVCl-atrol using cell-based mctabolomic approach, although transcriptomic and/or proteomic studies have also been conducted in the same in vi[ro cell experiment in some cases. Our integral analysis of the reviewed studies suggest that PCs may be involved not only in basic cellular processes or macro-and micro-nutrient meta- bolism, but also in specific metabolic pathways that have been thoroughly investigated. These modulated pathways could have a clinical impact on neurodegenerativc diseases, type 2 diabetes, cancer, and cardiovascular diseases. In conclusion, the in vitro metabolomic approaches provide additional information of the molecular mechanisms involved in disease risk reduction of dietary PCs. In order to elucidate the mechanisms of action of PCs, more metabolomic cell-based studies are nccdcd and testing the physiological conjugated forms of PCs in these cell systems could be of special interest.

We present a case of necrotizing pneumonia in an 87-year-old man without severe respiratory instability. Clinical suspicion arose due to the need for supplementary oxygen and persistent fever during treatment for community-acquired pneumonia. The diagnosis was confirmed by chest computed tomography. Although necrotizing pneumonia typically requires major surgical intervention upon diagnosis, we chose conservative management with antimicrobials and chest drainage alone. The patient experienced significant improvement and resolution of pneumonia with conservative management.
