[Dental treatment under general anesthesia among pediatric patients in 120 consecutive cases: a retrospective study].

PURPOSE： To investigate the clinical features of children who received treatment under dental general anesthesia (DGA). METHODS: The clinical records of dental patients below 18 years old who were treated under DGA at the Department of Pediatric Dentistry, Affiliated Dental Hospital of Kunming Medical University during June 2017 to November 2019 were obtained, including the baseline information, causes for DGA, anesthesia methods, intubation methods, treatment items, treatment time and follow-up visits.

Changes in key aroma-active compounds and sensory characteristics of sunflower oils induced by seed roasting.

This study investigated the changes in aroma composition and perception of sunflower oils induced by seed roasting using sensory-oriented flavor analysis. Volatile compounds were extracted by solvent-assisted flavor evaporation and headspace solid-phase microextraction. Odorants were characterized by gas chromatography-olfactometry-mass spectrometry and aroma extract dilution analysis.

Comparison of key aroma-active compounds between roasted and cold-pressed sesame oils.

This was the first study to compare the key aroma-active compounds that contributed to the different aroma profiles between roasted and cold-pressed sesame oils. Aroma compounds were extracted by headspace solid-phase micro-extraction (HS-SPME) and simultaneous distillation extraction (SDE) and were analysed using gas chromatography-olfactometry-mass spectrometry (GC-O-MS) and aroma extract dilution analysis (AEDA). The numbers of aroma-active compounds with the flavour dilution (FD) factors between 1 and 2048 were 57 and 16 in the roasted and cold-pressed sesame oils, respectively.

Molecular characterization of a cathepsin F-like protease in Trichinella spiralis.

Background: Trichinellosis is a re-emerging infectious disease, caused by Trichinella spp. Cathepsin F belongs to cysteine protease that is a major virulence factor for parasitic helminths, and it may be a potential anti-helminth drug target and vaccine candidate. The aim of this study was to clone, express and identify a cathepsin F-like protease in Trichinella spiralis and to investigate its biochemical characteristics.

The current status and challenges in the development of fusion inhibitors as therapeutics for HIV-1 infection.

HIV-1 membrane fusion as a part of the process of viral entry in the target cells is facilitated by gp41 and gp120, which are encoded by Env gene of HIV-1. Based on the structure and the mechanism researches, new treatment options targeting HIV-1 entry process have been proposed. Enfuvirtide, which mimics amino acid sequences of viral envelope glycoprotein gp41, is the first HIV-1 fusion inhibitor approved by FDA.
