Thermal ocular burns and evaluation of associated limbal stem cell deficiency in the light of global consensus.

Purpose: The aim of the present study is to examine the demographic data and clinical features of ocular surface injuries due to thermal burns and to evaluate LSCD in the light of global consensus.

Methods: Thirty-three eyes of 20 cases with ocular surface injury due to thermal burn who attended to the clinic between 2012 and 2023 were included in the study. LSCD severity was staged according to the global consensus which was published in 2019.

Factors Associated With Balance and Fear of Falling in Patients With Benign Paroxysmal Positional Vertigo: A Controlled Cross-Sectional Study.

Objectives: The aim of this study is to evaluate the factors influencing balance and fear of falling (FOF) in patients with benign paroxysmal positional vertigo (BPPV).

Design: A controlled cross-sectional study.

Setting: Single center study.

Anti-Adhesive Podocalyxin Expression Is Disrupted in Recurrent Implantation Failure.

The downregulation of anti-adhesive regulatory proteins and upregulation of adhesive genes are critical for the receptive endometrium. This study was designed to determine whether switching between the anti-adhesive podocalyxin (PDX) and adhesive HOXA10 receptivity modulator occurs in the endometrium of women with recurrent implantation failure (RIF). Twenty-four patients with RIF who could not conceive for three or more cycles despite good-quality embryo transfer constituted the study group.

Optical Centers in Cr-, Mn-, and O-Doped AlN and Their Thermodynamic Stability Designed by a Multiscale Computational Approach.

The optical centers in AlN can frequently exist in various charge states and can be accompanied by many coexisting defect species, creating a complex environment where mutual interactions are inevitable. Therefore, it is an immediate quest to design AlN crystal growth protocols that can target a specific optical center of interest and tune its concentration while preventing the formation of other unwanted point defects. Here, we provide a powerful workflow for point defect engineering in wide band gap, binary semiconductors that can be readily used to design optimal crystal growth protocols through combining CALPHAD-based phase analysis, and defect calculations.

Combined radiographic and ultrasound evaluations to decipher joint involvement in the hands of patients with systemic sclerosis.

Objective: The objective of this study was to explore the etiologies and contributing factors of synovial and tenosynovial involvement in SSc, as well as to assess the phenotype of patients with these synovial and tenosynovial features.

Methods: 171 SSc patients with hand manifestations (either vascular, skin or joint manifestations) who underwent standard X-rays of both hands and hand ultrasound (US), were included. Two independent evaluators recorded the presence or absence of acro-osteolysis, calcinosis, microcrystalline and degenerative rheumatisms, including osteophytosis on X-Rays.
