A Cohort Clinical Study on the Efficacy of Topical Salicylic Acid/Piroctone Olamine Dandruff Pre-Gel and Cleanser in Improving Symptoms of Moderate to Severe Seborrheic Dermatitis of the Scalp.

Background: Scalp seborrheic dermatitis (SD) is a chronic, recurrent inflammatory skin condition associated with scalp sebum secretion and dysbiosis.

Aims: The aim of this study is to evaluate the efficacy and safety of a topical salicylic acid/piroctone olamine/zinc salt of L-pyrrolidone carboxylate (Zinc PCA) scalp pre-application gel in combination with a salicylic acid/piroctone olamine/antimicrobial peptide cleansing lotion for the treatment of moderate to severe scalp SD.

Patients/methods: In this prospective cohort study, 20 patients with moderate to severe scalp SD were treated with a combination of the scalp pre-application gel and cleansing lotion for 4 weeks (one tube of the pre-application gel per week and the cleansing lotion used every 1-3 days depending on the frequency of hair washing).

Light-driven biodegradation of chloramphenicol by photosensitized Shewanella oneidensis MR-1.

Efficient and sustainable degradation of chloramphenicol has piqued the interest of the scientific community. This study constructed a photosensitized biohybrid system using Shewanella oneidensis MR-1 and cadmium sulfide (CdS). This system could efficiently degrade chloramphenicol with robust stability.

The incidence of lower extremity amputation and its associated risk factors in patients with diabetic foot ulcers: A meta-analysis.

This study analysed the incidence of lower extremity amputation and its associated risk factors in patients with diabetic foot ulcers. This study systematically searched both Chinese and English databases, including CNKI, Wanfang, VIP, PubMed, EMBASE and Web of Science, to identify cohort studies related to lower extremity amputation and associated risk factors in patients with diabetic foot ulcers up to October 2023. The patients were stratified based on whether they underwent lower extremity amputation, and relevant data, including basic information, patient characteristics, complications, comorbidities and pertinent laboratory test data, were extracted from the included studies.

Cobalt-doped double-layer α-FeO nanorod arrays for enhanced photoelectrochemical reduction of Cr(VI).

Element doping is an important method for improving the performance levels of photoelectrochemical (PEC) cells. Nevertheless, to date, the PEC conversion efficiency and photocurrent characteristics of the available photoanodes remain very low. In this study, cobalt (Co) was selectively doped into the bottom and/or top layers of double-layered α-FeO nanorod arrays grown on conductive transparent substrates (F:SnO, FTO) via a two-step hydrothermal method; this process was performed to enhance the charge transfer ability and thus significantly improve the PEC performance.

Light-driven biodegradation of azo dyes by Shewanella decolorationis-CdS biohybrid in wastewater lacking electron donors.

The lack of electron donors prevents the effective degradation of azo dyes by bacteria, which severely limits the practical application of conventional biological treatment. Herein, we innovatively designed a bio-photoelectric reduction degradation system composed of CdS and Shewanella decolorationis, which could effectively degrade amaranth in anaerobic conditions driven by light when electron donors were unavailable. Compared with bare S.

Computational fluid dynamics analysis of Trichosporon fermentans flocculation in refined soybean oil wastewater and flocculation rate prediction method.

Trichosporon fermentans can be used to treat refined soybean oil wastewater (RSOW) and produce microbial lipids. Bioflocculation is an effective method to recover Trichosporon fermentans which accumulates intracellular oils from wastewater. During the flocculation, the hydrodynamic distribution and parameters in the reactor are important limiting factors of yeast flocculation performance.

Integrated bioinformatics analysis of core regulatory elements involved in keloid formation.

Background: Keloid is a benign fibro-proliferative dermal tumor formed by an abnormal scarring response to injury and characterized by excessive collagen accumulation and invasive growth. The mechanism of keloid formation has not been fully elucidated, especially during abnormal scarring. Here, we investigated the regulatory genes, micro-RNAs (miRNAs) and transcription factors (TFs) that influence keloid development by comparing keloid and normal scar as well as keloid and normal skin.

A two-step process for pre-hydrolysis of hemicellulose in pulp-impregnated effluent with high alkali concentration to improve xylose production.

The viscose fiber production process is accompanied by the accumulation of pulp-impregnated effluent (PIE), including hemicellulose and large amounts of alkali, and discharge of PIE will cause environment pollution. This paper aims to relieve the inhibition of high concentration of alkali on xylose production from hydrolysis of hemicellulose in PIE. Based on the fact that solid acid uses H at the acid sites to exchange with cations in PIE and can be recycled, a two-step method including an extra pretreatment process before pre-hydrolysis (SPP) is proposed.

Computational fluid dynamics and factor analysis of a novel swirling demulsified airlift loop reactor for the treatment of refined soybean oil wastewater.

A swirling demulsified airlift loop reactor (SD-ALR) was developed for the treatment of oily wastewater with yeasts. Computational fluid dynamics simulations showed that the gas holdup and liquid velocity gradient in the SD-ALR were 2.9% and 0.
