Isolation and Identification of Four Strains of Bacteria with Potential to Biodegrade Polyethylene and Polypropylene from Mangrove.

With the rapid growth of global plastic production, the degradation of microplastics (MPs) has received widespread attention, and the search for efficient biodegradation pathways has become a hot topic. The aim of this study was to screen mangrove sediment and surface water for bacteria capable of degrading polyethylene (PE) and polypropylene (PP) MPs. In this study, two strains of PE-degrading bacteria and two strains of PP-degrading candidate bacteria were obtained from mangrove, named sp.

Clinical efficacy of Femoral Neck System for treatment of unstable femoral neck fractures in young adults.

Objective: This study was performed to evaluate the mid-term clinical efficacy of the Femoral Neck System (FNS) (DePuy Synthes, Zuchwil, Switzerland) in treating young patients with unstable Pauwels type III femoral neck fractures.

Methods: We performed a retrospective observational analysis of 21 young adults treated with the FNS. Clinical outcomes were assessed based on fracture reduction quality, Harris hip scores, and postoperative complication rates.

Mangrove plants are promising bioindicator of coastal atmospheric microplastics pollution.

Plastics are commonly used by society and their break down into millimeter-sized bits known as microplastics (MPs). Due to the possibility of exposure, reports of them in atmospheric deposition, indoor, and outdoor air have sparked worry for public health. In tropical and subtropical regions all throughout the world, mangroves constitute a distinctive and significant type of coastal wetlands.

Combined effects of microplastics and antibiotic-resistant bacteria on Daphnia magna growth and expression of functional genes.

Microplastics could act as vectors for the transport of harmful bacteria, such as pathogens and antibiotic resistance bacteria (ARB), but their combined effects have not been reported yet. Here, ARB Shigella flexneri with sulfonamides resistance and micro-polystyrene (micro-PS) were used to investigate their possible combined effects on the growth and expression of functional genes in Daphnia magna. Results showed that micro-PS colonized with S.

Characteristics of microplastic pollution and analysis of colonized-microbiota in a freshwater aquaculture system.

The microbial communities associated with microplastics (MPs) and their ambient environments have received wide attention. Although previous studies have reported the differences of microbial communities between MPs and natural environment or substrates, the effects of MPs on microbial balance and functions in ambient water remain unclear, particularly for aquaculture water. Here, we investigated the MPs pollution in farm ponds of grass carp located in the Foshan City of Guangdong Province and reported the distinction of bacterial structures, functions, and complexity between microbiota on MPs and in water.

Regulation of SOX10 stability via ubiquitination-mediated degradation by Fbxw7α modulates melanoma cell migration.

Dysregulation of SOX10 was reported to be correlated with the progression of multiple cancer types, including melanocytic tumors and tumors of the nervous system. However, the mechanisms by which SOX10 is dysregulated in these tumors are poorly understood. In this study, we report that SOX10 is a direct substrate of Fbxw7α E3 ubiquitin ligase, a tumor suppressor in multiple cancers.

Early stage alopecia areata is associated with inflammation in the upper dermis and damage to the hair follicle infundibulum.

Background/objectives: Alopecia areata (AA) is a non-scarring inflammatory hair loss disease. We investigated the early pathological changes of AA to identify possible factors participating in its pathogenesis.

Methods: Clinical, laboratory and pathological features of 87 AA patients were investigated.

Female pattern hair loss: clinico-laboratory findings and trichoscopy depending on disease severity.

Background: Female pattern hair loss (FPHL) is a progressive hair loss disorder with unclear triggering and supporting factors. Trichoscopic features of each stage of FPHL have not been specifically elaborated previously.

Aims: To analyze characteristics and investigate associations of clinico-laboratory and trichoscopic features of female patients in regard to the severity of hair loss in FPHL and to facilitate its diagnosis using noninvasive scalp dermoscopy (trichoscopy) in Fitzpatrick skin type III patients.

Effective treatment of folliculitis decalvans using selected antimicrobial agents.

Folliculitis Decalvans (FD) is a rare neutrophilic infammation of the scalp characterized by painful, recurrent purulent follicular exudation resulting in primary cicatricial alopecia. However, unclear etiology makes FD treatment a difficult task. A wide variety of topical and systemic agents have been tried previously, with varied results.
