Correlation between the facial skin microbiome and sensitive skin using the 2bRAD-M technique.

Objective: This study aimed to expound on the correlation between facial skin microbiome and sensitive skin (SS) using a novel sequencing technique.

Methods: We applied the 2bRAD sequencing for the microbiome, which enables accurate characterization of the low-biomass microbiome at species resolution to profile facial skin microbes in SS and non-SS groups. Further, the bacterial colonies were isolated and cultured from skin surfaces to study the pro-inflammatory effect on human keratinocytes by ELISA.

Dual-modular immunosensor for bongkrekic acid detection using specific monoclonal antibody.

Bongkrekic acid (BA) is a mitochondrial toxin that causes high mortality but is often mistakenly categorized as other food poisonings. The immunoassay of BA is still challenging since the specific antibody is unavailable. In this work, a monoclonal antibody specific to BA was first generated and a dual-modular immunosensor for on-site and laboratory detection was established.

Modulation of TRPV1 function by Citrus reticulata (tangerine) fruit extract for the treatment of sensitive skin.

Background: Sensitive skin (SS) is a clinical syndrome defined by the occurrence of unpleasant sensations (such as stinging, burning, pain, pruritus, and tingling) in response to stimuli that normally should not provoke them. According to growing evidence, transient receptor potential vanilloid subtype 1 (TRPV1) has elevated expression in individuals with SS and is linked with the severity of SS symptoms. However, its pathogenesis is still unknown.

Demographic profile and ocular characteristics of stage 5 retinopathy of prematurity at a referral center in Northwest China: implications for implementation.

Background: Severe retinopathy of prematurity (ROP) with extremely unfavorable prognosis among infants can do great damage to individuals and bring tremendous social-economic burden. The purpose of this study is to describe the demographic and ocular characteristics of infants who presented with stage 5 ROP in order to identify reasons why they have become blind, and to identify contributing factors in order to focus great attention on the current ROP program and to inspire more effort in ROP screening in middle income countries.

Methods: A retrospective review of consecutive infants with stage 5 ROP from December 2010 to December 2016 in Department of Ophthalmology, Xijing Hospital.

A novel class of antagonists for the FFAs receptor GPR40.

The free fatty acid receptor, GPR40, is implicated in the pathophysiology of type 2 diabetes, and is a new potential drug target for the treatment of type 2 diabetes. Its antagonist is thought to be not only a useful chemical probe for further exploring the function of GPR40 but also a lead structure for drug development. With virtual screening based on a homology model followed by a cell-based calcium mobilization assay, we found that sulfonamides are a new class of small organic antagonists for GPR40.
