Research on manipulating materials using light has garnered significant interest, yet examples of controlling electronic polarization in magnetic materials remain scarce. Here, the hysteresis of electronic polarization in the anti-ferromagnetic semiconductor FePS is demonstrated via light. Below the Néel temperature, linear dichroism (i.

Naturally occurring genetic variants in the TVA gene determine susceptibility or resistance to ALV-A and -K, but the effects of these mutated TVA on vitamin B uptake have not been investigated systemically. We found four TVA variants comprising the wild type (TVA), a single nucleotide polymorphism variant (TVA), and two partial deletions in the splicing branch point region (TVA).

Objective: This study aims to identify crucial factors influencing the perception of severe AA from the patients' viewpoint.
Methods: A web-based survey was conducted among AA patients attending dermatology departments at 21 university hospitals in Korea.
Background: Hair transplantation (HT) has been reported to be effective for the treatment of female-pattern hair loss (FPHL). Few studies have investigated HT in FPHL.
Objective: To evaluate the clinical features of FPHL treated with HT and analyze the real-world results of HT.
Human genes have numerous copy number variations (CNVs) and single-nucleotide polymorphisms (SNPs) that control most of the body's core functions. On average, 12-16 % of human genes have CNVs, and a single gene can have a few hundred to several thousand SNPs. Numerous genome-wide association studies (GWAS) have shown that CNVs and SNPs can coexist in certain genomic regions, amplifying their effects on gene expression and regulation and disease susceptibility.

This study was performed to investigate the cutaneous effects of using a fractional picosecond laser at 1064 nm with a diffractive lens.
Methods: The penetration depth according to the location of the handpiece tip was evaluated using an acrylic panel.
Background: Androgenetic alopecia (AGA) is a prevalent hair loss disorder with psychological repercussions. Traditional treatments have limitations, leading to the exploration of regenerative therapies such as exosomes derived from adipose tissue stem cells (ASC-Exosomes).
Methods: First, using human hair follicle (HF) dermal papilla cells (hDPCs) treated with ASC-Exosomes, ALP, VCAN, β-catenin, and LEF-1 levels with RT-PCR and p-GSK3β, GSK3β, β-catenin, ALP, and β-actin levels with western blot analysis were assessed.
Hair growth cycles are mainly regulated by human dermal papilla cells (hDPCs) and human outer root sheath cells (hORSCs). Protecting hDPCs from excessive oxidative stress and hORSCs from glycogen phosphorylase (PYGL) is crucial to maintaining the hair growth phase, anagen. In this study, we developed a new PYGL inhibitor, Hydroxytrimethylpyridinyl Methylindolecarboxamide (HTPI) and assessed its potential to prevent hair loss.

Thus, to enhance PGE levels while improving hair loss, we found dihydroisoquinolinone piperidinylcarboxy pyrazolopyridine (DPP), an inhibitor of 15-hydroxyprostaglandin dehydrogenase (15-PGDH), using DeepZema, an AI-based drug development program. Here, we investigated whether DPP improved hair loss in human follicle dermal papilla cells (HFDPCs) damaged by dihydrotestosterone (DHT), which causes hair loss.

Methods: We compared the bleeding time (BT) of sampling by using a laser-lancing-device (LMT-1000) and a conventional lancet in patients with DM and thrombocytopenia or patients undergoing DAPT. BT was measured using the Duke method, and pain and satisfaction scores were assessed using numeric rating scale (NRS) and visual analog scale (VAS).
While many gene expression studies have focused on male pattern baldness (MPB), few studies have investigated the genetic differences between bald and non-bald hair follicles in female pattern hair loss (FPHL). This study aimed to identify molecular biomarkers associated with FPHL through genetic analysis of paired bald and non-bald hair follicles from 18 FPHL patients, using next-generation sequencing (NGS) techniques. RNA transcriptome analysis was performed to identify differentially expressed genes (DEGs) between bald and non-bald hair follicles in FPHL.

However, it remains unclear if a sufficient number of residency programs with quality standards exist, as there has been little research on this subject in South Korea.
Objective: To identify the status of surgical dermatology education among residents and assess dermatologists' perceptions of the subject.
Circulating tumor DNA (ctDNA) detection has been acknowledged as a promising liquid biopsy approach for cancer diagnosis, with various ctDNA assays used for early detection and treatment monitoring. Dispersible magnetic nanoparticle-based electrochemical detection methods have been proposed as promising candidates for ctDNA detection based on the detection performance and features of the platform material. This study proposes a nanoparticle surface-localized genetic amplification approach by integrating FeO-Au core-shell nanoparticles into polymerase chain reactions (PCR).

Our study highlights the versatility of tip-assisted terahertz spectroscopy in probing coherent magnons, the elementary quanta of spin waves in magnetic materials. We identify two distinct coherent magnon types in canted antiferromagnet YFeO. The remarkable consistency with far-field terahertz spectroscopy in crucial magnon parameters, such as coherence time and resonance frequency, firmly establishes the credibility of tip-assisted terahertz spectroscopy.

To resolve this issue, we developed a technology for the construction of a humanhair construct based on the assemblage of different types of cells present in the hair organ. First, we demonstrated that epithelial cells, when isolated, have similar genetic signatures regardless of their dissection site, and their trichogenic potential is dependent on the culture conditions.
