Development and validation of a risk prediction model related to inflammatory and nutritional indexes for postoperative pulmonary infection after radical colorectal cancer surgery.

Objective: To develop and validate a risk prediction model related to inflammatory and nutritional indexes for postoperative pulmonary infection (POI) after radical colorectal cancer (CRC) surgery.

Design: Cross-sectional study.

Participants: This study analysed 866 CRC patients after radical surgery at a tertiary hospital in China.

An efficient utilization of high chromium vanadium slag: Extraction of vanadium based on manganese carbonate roasting and detoxification processing of chromium-containing tailings.

A novelty roasting method with manganese carbonate (MnCO) as additive was carried out to separate and recover vanadium from high chromium vanadium slag (HCVS) efficiently. Vanadium tailings containing chromium was detoxified by carbon reduction and smelting to form Fe-Cr alloy. The whole process of HCVS utilization was analyzed by X-ray diffraction (XRD) and scanning electron microscopy (SEM).

An efficient utilization of chromium-containing vanadium tailings: Extraction of chromium by soda roasting-water leaching and preparation of chromium oxide.

Chromium-containing vanadium tailings (CCVT), an industrial waste, were utilized to extract chromium efficiently by soda roasting-water leaching process and for the preparation of highly pure chromium oxide. The effect of extraction of chromium under different roasting and leaching conditions were analyzed using X-ray diffraction (XRD) and scanning electron microscopy (SEM). The maximum chromium extraction rate of 91.

Effect of propofol on mitochondrial ATP content and ATPase activity in hippocampus of rats with cerebral ischemia-reperfusion injury.

Objective: Study on the influence of the cerebral Ischemia-reperfusion Injury (IRI) on mitochondrial adenosine triphosphate (ATP) content and ATPase activity in hippocampus of rats, as well as the protective effect of propofol on IRI in rats.

Methods: A total of 40 male SD rats were randomly divided into 5 groups: sham operation group (Group A), ischemia reperfusion control group (Group B) and ischemic reperfusion with propofol pretreatment group (C group). Group C was further divided into three sub groups according to the different doses of propofol: Group C1 (50 mg/kg), Group C2 (100 mg/kg) and Group C3 (150 mg/kg).

Arabidopsis MAPKKK18 positively regulates drought stress resistance via downstream MAPKK3.

Mitogen-activated protein kinase (MAPK) cascades are conserved and vital signaling components in the responses to various ambient stresses. Here, we report the identification of MAPKKK18, a drought resistance associated MAPK kinase kinase in Arabidopsis. The mapkkk18 knockout mutants displayed hypersensitivity to drought stress, whereas overaccumulation of MAPKKK18 in transgenic Arabidopsis plants significantly enhanced the resistance to drought.
