Association Between Serum Trace Elements Level and Alopecia Areata: A Systematic Review and Meta-Analysis.

Background: Alopecia areata (AA) is a prevalent autoimmune disorder in dermatology, impacting 0.5%-2% of the general population worldwide. More and more scholars are focusing on the important role of micronutrients in the occurrence and development of AA.

Promotion of mandibular distraction osteogenesis by parathyroid hormone via macrophage polarization induced through iNOS downregulation.

Objective: To investigate whether Parathyroid hormone (PTH) can promote mandibular distraction osteogenesis by regulating macrophage polarization and the underlying mechanisms of this phenomenon.

Methods: Forty-eight Rabbits were used to establish the mandibular distraction osteogenesis experimental model, randomly divided into 2 groups. Intermittent post-operative injections of 20 μg/kg PTH and normal saline were administered to the experimental and control groups, respectively.

Analysis of the pluripotent and germline marker gene expression, and the state of X chromosome reactivation of primordial germ cells in pig gonads.

The gonadal primordial germ cells (PGCs) possess a unique state of pluripotency and X chromosome activity. However, extensive evidence indicates developmental variability in PGCs across different species. This study aims to evaluate the pluripotency status, specific gene expression patterns, and X chromosome reactivation (XCR) of pig gonadal PGCs.

Current global research on mandibular defect: A bibliometric analysis from 2001 to 2021.

Mandibular defects can result from congenital deformities, trauma, tumor resection, and osteomyelitis. The shape was irregular because the lower jaw was radians. This involves teeth and jaw functions; therefore, the difficulty of bone repair is greater than that in other body parts.

Chemical stabilization of heavy metals in municipal solid waste incineration fly ash: a review.

Sufficient attention should be attached to the large amount of fly ash containing high levels of toxic heavy metals generated after municipal solid waste incineration. Because heavy metals could be leached out of the fly ash under specific conditions, it is necessary to stabilize the heavy metals in fly ash before landfill disposal. Processing technologies of incineration fly ash include solidification/stabilization technology, thermal treatments, and separation processes.

The Diagnostic Value of Serum Ferritin for Telogen Effluvium: A Cross-Sectional Comparative Study.

Purpose: This study aimed to explore the relationship between serum ferritin levels and telogen effluvium.

Patients And Methods: A total of 193 telogen effluvium patients and 104 female androgenetic alopecia patients were included. We collected the test result of serum ferritin levels, compared with the results of 183 healthy subjects.

Innovative use of concentrated growth factors combined with corticosteroids to treat discoid lupus erythematosus alopecia: A case report.

Alopecia for patients with discoid lupus erythematosus can sometimes be a refractory condition, where mixed infiltrates of T lymphocytes and histiocytes leads to destruction of hair follicles, which might cause permanent scarring. Early diagnosis and timely treatment can achieve hair regeneration and prevent further disease progression. Concentrated growth factor, a novel autologous plasma extract, contains various growth factors that could promote tissue regeneration.

Multi-stage surgery combined with radiotherapy for treatment of giant anterior chest wall keloid: A case report.

Rationale: Giant keloids often have indications for surgical resection, but postoperative reconstruction of the skin and high recurrence of keloids are a challenge for clinical treatment. This article reports a rare successful treatment of a giant keloid in the anterior chest wall by multistage surgery combined with radiotherapy, which is why this case is meaningful.

Patient Concerns: A 66-year-old woman presented a giant keloid with ulcerations and severe itching on the anterior chest wall.

Study on an effective industrial waste-based adsorbent for the adsorptive removal of phosphorus from wastewater: equilibrium and kinetics studies.

In this work, an effective adsorbent for removing phosphate from aqueous solution was developed from modifying industrial waste--lithium silica fume (LSF). The characterization of LSF before and after modification was investigated using an N2 adsorption-desorption technique (Brunauer-Emmett-Teller, BET), scanning electron microscopy (SEM) and X-ray diffraction (XRD). Studies were conducted to investigate the effect of adsorbent dose, initial solution pH, contact time, phosphate concentration, and temperature on phosphate removal using this novel adsorbent.

Inactivation of dinoflagellate Scripsiella trochoidea in synthetic ballast water by advanced oxidation processes.

Ship-borne ballast water contributes significantly to the transfer of non-indigenous species across aquatic environments. To reduce the risk of bio-invasion, ballast water should be treated before discharge. In this study, the efficiencies of several conventional and advanced oxidation processes were investigated for potential ballast water treatment, using a marine dinoflagellate species, Scripsiella trochoidea, as the indicator organism.

Application of excitation and emission matrix fluorescence (EEM) and UV-vis absorption to monitor the characteristics of Alizarin Red S (ARS) during electro-Fenton degradation process.

Oxidative degradation of Alizarin Red S (ARS) in aqueous solutions by using electro-Fenton was studied. At first, effect of operating parameters such as current density, aeration rate and initial pH on the degradation of ARS were studied by using UV-vis spectrum, respectively. Then, under the optimal operating conditions (current density: 10.
