Sarcopenia adversely impacts clinical outcomes in patients undergoing pancreaticoduodenectomy: A systematic review and meta-analysis.

Background: Sarcopenia is a syndrome marked by a gradual and widespread reduction in skeletal muscle mass and strength, as well as a decline in functional ability, which is associated with malnutrition, hormonal changes, chronic inflammation, disturbance of intestinal flora, and exercise quality. Pancreatoduodenectomy is a commonly employed clinical intervention for conditions such as pancreatic head cancer, ampulla of Vater cancer, and cholangiocarcinoma, among others, with a notably high rate of postoperative complications. Sarcopenia is frequent in patients undergoing pancreatoduodenectomy.

Functional roles of C/EBPα and SUMO‑modification in lung development.

CCAAT enhancer binding protein alpha (C/EBPα) is a transcription factor regulating the core aspects of cell growth and differentiation. The present study investigated the level and functional role of C/EBPα during the development of the rat lung. C/EBPα protein exhibits a dynamic expression pattern.

Extraction and purification of capsaicin from capsicum oleoresin using an aqueous two-phase system combined with chromatography.

Capsaicin was extracted from capsicum oleoresin using an aqueous two-phase system (ATPS) composed of an ethylene oxide-propylene oxide (EOPO) copolymer, salt and ethanol. Capsaicin was concentrated in the top polymer-rich phase. To determine the optimal conditions, the partitioning of capsaicin in the ATPS was investigated, considering a single-factor experiment including the salt concentration, polymer concentration, buffer pH, ethanol concentration, sample loading and extraction duration.

Aqueous two-phase extraction combined with chromatography: new strategies for preparative separation and purification of capsaicin from capsicum oleoresin.

Capsaicin was preparatively separated and purified from capsicum oleoresin with a new method combined with aqueous two-phase extraction (ATPE) and chromatography. Screening experiments of ATPE systems containing salts and hydrophilic alcohols showed that potassium carbonate/ethanol system was the most suitable system for capsaicin recovery among the systems considered. Response surface methodology was used to determine an optimized aqueous two-phase system for the extraction of capsaicin from capsaicin oleoresin.

Combination of aqueous two-phase extraction and cation-exchange chromatography: new strategies for separation and purification of alliin from garlic powder.

In this study, a two-step process combining aqueous two-phase extraction (ATPE) with chromatography was developed for extraction and purification of alliin from garlic powder. The partition coefficient and yield value of alliin in different types of aqueous two-phase system (ATPS) were compared and response surface methodology (RSM) was used for analyzing and optimizing the extraction process. The optimal extraction conditions of 19% (w/w) (NH4)2SO4, 20% (w/w) 1-prpanol, at 30°C, pH 2.
