Tartrazine, an azo dye prevalent in pharmaceuticals and food items, was investigated for its impact on fetal development, specifically examining visceral and skeletal abnormalities in rat offspring exposed to daily oral doses throughout pregnancy. Fourteen pregnant rats were randomly assigned to control and tartrazine groups (seven animals each), with tartrazine administered via oral gavage at 7.5 mg/kg throughout gestation.

Article Synopsis
  • - Sepsis is a serious condition characterized by inflammation and cell death, often leading to multiple organ failure, requiring quick medical attention; lipopolysaccharide (LPS) triggers inflammatory responses through specific receptors like TLR-2.
  • - The study explores the role of melatonin (MEL) in reducing lung injury caused by LPS-induced septic shock in rats, highlighting its potential to lower the expressions of inflammatory markers NEK7, TLR2, and NLRP3.
  • - Results showed that melatonin treatment reduced lung tissue damage, cell infiltration, and wall thickening, indicating that it may provide therapeutic benefits in managing sepsis-related acute lung injury.

Objective: The aim of this study was to investigate difficulties in emotion regulation, emotional eating, and impulsivity in children diagnosed with type 1 diabetes mellitus (T1DM).

Materials And Methods: The study included 53 children who were diagnosed with T1DM, and a control group of 50 subjects. The Schedule for Affective Disorders and Schizophrenia for School-age Children-Present and Lifetime Version, Difficulties in Emotion Regulation Scale- Short Form (DERS-16), Emotional Eating Scale-Child and Adolescent Form (EES-C), and the Barratt Impulsivity Scale 11-Short Form (BIS-11) were administered to the participants.

To investigate adipokines (vaspin, omentin-1, adiponectin and leptin) and their correlation with hepatosteatosis degree in obese/overweight (O/O) children. We analyzed adipokine levels of 81 children (49 O/O, [body mass index (BMI) > 95] and 32 non-obese (BMI = 5-85) admitted to the pediatric outpatient clinic. Serum triglyceride, glucose, low density lipoprotein-cholesterol, total cholesterol, high density lipoprotein-cholesterol, alanine aminotransferase, aspartate aminotransferase (AST), insulin, HbA1c levels and leptin, omentin-1, vaspin, adiponectin levels were studied.

A series of thin Pt-Co films with different metal ratios were deposited by using the sequential cosputtering directly on a commercial hydrophobic carbon paper substrate at room temperature and in ultra-high vacuum (UHV) conditions. Their electrocatalytic properties toward the oxygen reduction reaction were investigated in 0.5 M HSO solution by means of cyclic voltammetry (CV) and linear sweep voltammetry (LSV) on rotating disc electrode (RDE).

Objective: To compare volumetric arc therapy (VMAT) and helical tomotherapy (HT) plans in terms of dosimetric parameters in positron emission tomography- (PET-) computerized tomography- (CT-) based radiation therapy planning in unresectable malignant pleural mesothelioma (MPM).

Methods: CT and coregistered PET-CT data from seven patients with histologically-proven MPM were utilized for VMAT and HT plans. Target volumes and organs at risk (OARs) were delineated.

Lithium-Sulfur (Li-S) batteries are mostly known for their high energy density and cost-effectiveness. However, their intrinsic problems hinder their implementation into the marketplace. The most pronounced problems are the parasitic reactions which occur between lithium polysulfides species and lithium metal anode, the volume expansion of sulfur (80%) at the end of discharge and the safety issues which are linked with the use of lithium metal.

Chronic obstructive pulmonary disease (COPD) is a lung disease characterized with limitation of airflow that is not completely reversible, progressive deterioration of airways and systemic inflammation. This study has been planned to determine daily symptom variability of patients, expectations of patient and physicians from treatment and patient profiles. A total of 514 patients with COPD from 25 centers were included in this national, multicenter, cross-sectional observational study.

Background: The International Diabetes Federation (IDF) defines metabolic syndrome among children. In addition to the abdominal obesity (waist circumference ≥90 percentile of locally representative sample), the risk criteria for metabolic syndrome includes elevated blood pressure, hypertriglyceridemia, low high-density lipoprotein cholesterol (HDL-C) levels, and elevated fasting glucose. In this study, we compared the association of anthropometric indices with metabolic syndrome risk criteria in 9-year-old children.

Although renal and cardiac malformations are commonly seen in Turner syndrome (TS), anorectal malformations, multicystic dysplastic kidney and interrupted aortic arch are quite rare in TS. A newborn with TS with three quite rare congenital malformations (imperforate anus/anal atresia associated with rectovestibular fistula, interrupted aortic arch, and multicystic dysplastic kidney) is presented.

We report studies on the modifications induced by the evaporation of copper overlayers on a self-assembled monolayer (SAM) of the oligo(phenylene-ethynyl) dithiol, 1-thio-4-[4'-[(4'-thio)phenylethynyl]-1'-ethynyl]-benzene (TTPEB). These SAMs were characterized after deposition from a tetrahydrofuran solution on polycrystalline gold substrates and after copper evaporation and its subsequent removal by nitric acid. Monolayers were studied via cyclic voltammetry (CV), UV-vis multiwavelength ellipsometry, external reflectance infrared (IR) spectroscopy, and ion scattering spectroscopy (ISS).
