Trajectory and determinants of intensive care unit-acquired weakness in critical illness: A multicentre, prospective, longitudinal study.

Background: Intensive care unit-acquired weakness (ICU-AW) is prevalent and adversely affects patient outcomes. Muscle strength progression and response to rehabilitation differ across ICU populations. However, the trajectories, determinants and prognoses of muscle strength changes remain unclear.

Effects of a multilevel intervention of resistance training with or without beta-hydroxy-beta-methylbutyrate in medical ICU patients during entire hospitalisation: a four-arm multicentre randomised controlled trial.

Background: Intensive care unit-acquired weakness (ICU-AW) is a prevalent and severe issue among ICU patients. Resistance training and beta-hydroxy-beta-methylbutyrate (HMB) intervention have demonstrated the potential to enhance muscle function in patients with sarcopenia and in older adults. The purpose of this study was to determine whether resistance training and/or HMB administration would improve physical function, muscle strength, and quality of life in medical ICU patients.

The Specifically Androgen-Regulated Gene (SARG) Promotes Papillary Thyroid Carcinoma (PTC) Lymphatic Metastasis Through Vascular Endothelial Growth Factor C (VEGF-C) and VEGF Receptor 3 (VEGFR-3) Axis.

The papillary thyroid carcinoma (PTC) metastasizes through lymphatic spread, but the follicular thyroid cancer (FTC) metastasis occurs by following hematogenous spread. To date, the molecular mechanism underlying different metastatic routes between PTC and FTC is still unclear. Here, we showed that specifically androgen-regulated gene (SARG) was significantly up-regulated in PTC, while obviously down-regulated in FTC through analyzing the Gene Expression Omnibus (GEO) database.

A novel chiral inorganic mesoporous silica used as a stationary phase in GC.

Chiral mesoporous silica (CMS) has attracted widespread attention because of some unique properties, such as high surface area, uniformly structured nanoscale cavities, and excellent chemical and thermal stability. In this work, we report the utilization of a CMS as the stationary phase for the separation of racemates in gas chromatography (GC). A CMS-coated capillary column was fabricated by a dynamic coating method.

Optical resolution and mechanism using enantioselective cellulose, sodium alginate and hydroxypropyl-β-cyclodextrin membranes.

Chiral solid membranes of cellulose, sodium alginate, and hydroxypropyl-β-cyclodextrin were prepared for chiral dialysis separations. After optimizing the membrane material concentrations, the membrane preparation conditions and the feed concentrations, enantiomeric excesses of 89.1%, 42.

Solid-phase extraction with metal-organic frameworks for the analysis of chiral compounds.

Metal-organic frameworks (MOFs) are excellent porous materials with nanoscale cavities and high surface areas, which make them promising as novel adsorbents in solid-phase extraction (SPE). In this article we report a new application of the chiral MOF [Zn (D-Cam) (4,4'-bpy)] in SPE used for the measurement of the enantiomeric excess (ee) of (±)-1,1'-bi-2-naphthol. Several important experimental parameters that may influence the extraction efficiency were investigated and optimized.

[Preparative separation of alkaloids from Cortex Phellodendri by high speed countercurrent chromatography].

High speed countercurrent chromatography was successfully applied to the separation of alkaloids from Cortex Phellodendri with a two-phase solvent system composed of CHCl3-CH3OH-0.5 mol/L HCl (2:1:1, volume ratio). Some alkaloid components were obtained, and identification of berberine was made by thin-layer chromatography.
