Impact of oral isotretinoin on the inflammatory markers: can lymphocyte/HDL-C and platelet/HDL-C ratios be new indicators of inflammation in acne vulgaris patients?

Introduction: The effect of isotretinoin on inflammatory markers has been reported with conflicting results. No studies have been reported on the relationship between isotretinoin and lymphocyte/high-density lipoprotein cholesterol [HDL-C] ratio (LHR), neutrophil/HDL-C ratio (NHR), or platelet/HDL-C ratio (PHR) in acne patients.

Objectives: We aimed to investigate how isotretinoin affects the inflammatory markers, including LHR, NHR, and PHR, in acne vulgaris patients.

Asprosin-induced alterations in female rat puberty and reproductive hormonal profiles.

Objective: To investigate the comprehensive effects of daily chronic asprosin administration on various pubertal and reproductive parameters in female rats. This study aims to elucidate the role of asprosin in regulating the onset of puberty and its influence on hormonal profiles and ovarian histology.

Methods: Asprosin was administered intraperitoneally (i.

Immunoexpression Patterns of Adhesion Molecules (E-cadherin, β-catenin, CD56) and Cytokeratins (CK19, CK20, HMWCK, CAM5.2) During Hair Development in Human Fetuses Compared With Adults.

Abnormalities in the expression of cytokeratins or adhesion molecules have been associated with hair disorders. The expression patterns of these molecules in the hair follicles of developing human fetuses are not obvious. We aimed to investigate the expression patterns of some cytokeratins and adhesion molecules in the hair follicle of human fetuses and compared them with adults.

Analysis of factors influencing target PASI responses and side effects of methotrexate monotherapy in plaque psoriasis: a multicenter study of 1521 patients.

Methotrexate (MTX) is commonly used as first-line systemic treatment agent in psoriasis. We aimed to evaluate the clinical characteristics and treatment responses of patients with psoriasis undergoing MTX monotherapy. Data from adult patients with plaque psoriasis who received MTX monotherapy for at least 3 months between April 2012 and April 2022 were retrospectively evaluated in 19 tertiary care centers.

Analytical Validation of a Spiral Microfluidic Chip with Hydrofoil-Shaped Pillars for the Enrichment of Circulating Tumor Cells.

The isolation of circulating tumor cells (CTCs) from peripheral blood with high efficiency remains a challenge hindering the utilization of CTC enrichment methods in clinical practice. Here, we propose a microfluidic channel design for the size-based hydrodynamic enrichment of CTCs from blood in an epitope-independent and high-throughput manner. The microfluidic channel comprises a spiral-shaped part followed by a widening part, incorporating successive streamlined pillars, that improves the enrichment efficiency.

Stathmin 1 and p53 Expression in Cutaneous Squamous Cell Carcinoma and Precursor Lesions.

Studies on the relationship between stathmin 1 (STMN1) and cutaneous squamous cell carcinoma (cSCC) are limited. We aimed to evaluate the relationship between clinicopathological factors and STMN1 and p53 expressions in cSCC and compare them with those in the precursor lesions of cSCC and normal tissue. A total of 195 patients, followed between January 2014 and December 2021, with diagnoses of primary cSCC (n = 129), in situ cSCC (n = 20), or actinic keratosis (n = 46), as well as 29 histopathologically normal tissue samples, were included in the study.

A microfluidic device enabling drug resistance analysis of leukemia cells via coupled dielectrophoretic detection and impedimetric counting.

We report the development of a lab-on-a-chip system, that facilitates coupled dielectrophoretic detection (DEP-D) and impedimetric counting (IM-C), for investigating drug resistance in K562 and CCRF-CEM leukemia cells without (immuno) labeling. Two IM-C units were placed upstream and downstream of the DEP-D unit for enumeration, respectively, before and after the cells were treated in DEP-D unit, where the difference in cell count gave the total number of trapped cells based on their DEP characteristics. Conductivity of the running buffer was matched the conductivity of cytoplasm of wild type K562 and CCRF-CEM cells.

A Novel Microfluidic Method Utilizing a Hydrofoil Structure to Improve Circulating Tumor Cell Enrichment: Design and Analytical Validation.

Being one of the major pillars of liquid biopsy, isolation and characterization of circulating tumor cells (CTCs) during cancer management provides critical information on the evolution of cancer and has great potential to increase the success of therapies. In this article, we define a novel strategy to effectively enrich CTCs from whole blood based on size, utilizing a spiral microfluidic channel embedded with a hydrofoil structure at the downstream of the spiral channel. The hydrofoil increases the distance between the streams of CTCs and peripheral blood cells, which are already distributed about two focal axes by the spiral channel, thereby improving the resolution of the separation.

Enhancement of the Start-Up Time for Microliter-Scale Microbial Fuel Cells (µMFCs) via the Surface Modification of Gold Electrodes.

Microbial Fuel Cells (MFCs) are biological fuel cells based on the oxidation of fuels by electrogenic bacteria to generate an electric current in electrochemical cells. There are several methods that can be employed to improve their performance. In this study, the effects of gold surface modification with different thiol molecules were investigated for their implementation as anode electrodes in micro-scale MFCs (µMFCs).

Cyclosporine-A for severe childhood atopic dermatitis: clinical experience on efficacy and safety profile.

Background/aim: Management of atopic dermatitis (AD) in children is still challenging. The aim of this study was to evaluate the efficacy and safety profile of cyclosporine-A (CsA) treatment in children with severe and recalcitrant AD. Materials and methods: Medical records of 43 children followed between January 2010 and December 2015 and treated with systemic CsA were evaluated retrospectively.

Retrospective Analysis of 91 Kaposi's Sarcoma Cases: A Single-Center Experience and Review of the Literature.

Background: Kaposi's sarcoma (KS) is a multifocal angioproliferative tumor involving primarily the skin.

Objective: The aim of this study was to describe the clinical, demographic, histopathological characteristics, treatment modalities, and outcome of 91 KS patients, and compare them with other contemporary research.

Methods: Medical records of 91 KS patients followed between January 2005 and September 2017 were evaluated retrospectively.
