Autism spectrum disorder (ASD) is characterized by deficits in social interaction, restricted interests, and repetitive behaviors. Several genes, including synaptic proteins and environmental risk factors, play a role in the etiology of autism. We aimed to evaluate the relationship between neuroligin-1 (NLGN-1) and neuroligin-3 (NLGN-3) levels, which are neuronal cell adhesion molecules (CAMs), and inflammatory cytokine (IL-6, IL-8) levels with disease severity and symptom clusters and with each other in children with ASD.

Introduction: Our study aimed to compare the sociodemographic, diagnostic, clinical, and self-report scale data of adults diagnosed with ADHD in childhood/adolescence versus adulthood and to identify risk factors associated with delayed/missed diagnosis for ADHD.

Method: Sociodemographic, clinical, and diagnostic data of 214 adults with ADHD, followed at the Adult Neurodevelopmental Disorders Clinic, Selçuk University, between January 2022 and January 2024, were analyzed. The diagnostic evaluations were made using the Structured Clinical Interview for DSM-5 Clinician Version.

Objectives: This study investigated the utility of specific predictive and discriminative items within the Social Communication Questionnaire (SCQ) for distinguishing between autism spectrum disorder (ASD), intellectual disability (ID), and co-occurring ASD + ID in children.

Methods: A total of 137 children aged 4 to 12 years (52 typically developing (TD), 34 ASD, 26 ID, 25 ASD + ID) were included in the study. Cognitive development assessments were conducted for the ASD, ID, and ASD + ID groups in suitable cases.

Introduction: Absence of mismatch repair (MMR) genes in tumor cells or errors in the replication repair process may lead to DNA-MMR deficiency and microsatellite instability (MSI) formation. Specific tumor environments where gene variations are observed are believed to be conducive to the formation of MSI. This study aimed to determine the MSI status, MMR protein expression, and somatic mutation profile in solid organ tumors.

The plasmid pAnox1, isolated from Anoxybacillus gonensis 05S15, was sequenced and characterized as a circular, double-stranded DNA molecule of 1592 base pairs with a GC content of 40.01 %. Despite its cryptic nature and small genome, bioinformatic analyses identified conserved motifs associated with replication-related proteins, though BLAST searches revealed no significant homology with other plasmids.

Article Synopsis
  • The study looked at two types of surgeries for women who have a problem called stress urinary incontinence (SUI), comparing autologous fascial slings (AFS) and retropubic synthetic slings (RP).
  • Researchers found that both surgeries had similar success rates in helping women feel better, but AFS surgeries took longer to perform.
  • They concluded that more research is needed to help doctors and patients make better decisions about which surgery to choose for treating SUI.

Objectives: In the present study we investigated the relationship between interpersonal childhood trauma, ability to delay gratification (DG), and disordered eating attitudes among adolescents.

Methods: Data were collected from 145 adolescents aged 12 to 17 through an online survey distributed to parents and legal guardians. The sociodemographic data form, Childhood Trauma Questionnaire (CTQ), Eating Attitudes Test-26 (EAT-26), and Delaying Gratification Inventory were filled out by adolescents in the study.

Article Synopsis
  • The coxal bone is essential for movement, stability, and childbirth, yet there has been little research on its geometric properties, particularly the golden ratio.
  • This study measured 95 adult dry coxal bones using 18 morphometric parameters, identifying consistent ratios between various anatomical lengths of the bone.
  • The findings suggest that these constant ratios could aid surgeons in making more accurate measurements during surgical procedures related to the coxal bone, potentially reducing complications.

Background/aims:  Hepatocellular carcinoma is a major cause of mortality and morbidity in both cirrhotic and non-cirrhotic patients, and most patients are suitable for locoregional and/or systemic therapy at the time of diagnosis. In this study, we aimed to determine the efficacy and safety of transarterial radioembolization in elderly patients.

Materials And Methods:  Patients diagnosed with hepatocellular carcinoma between 2013 and 2022 were screened retrospectively.

Introduction: Chronic spontaneous urticaria (CSU) is characterized by persistent or recurrent pruritic lesions that last more than 6 weeks. Patients with CSU may experience sleep disturbances, particularly due to itching. Biological rhythms (chronotypes) are categorized as morningness, intermediate, and eveningness types.

Purpose: To investigate whether serum hormone (testosterone, prolactin, gonadotropins, and thyroid hormones) and vitamin (vitamin B, folic acid, and vitamin D) levels are associated with premature ejaculation (PE).

Materials And Methods: This prospective case-control study included 126 patients with PE (lifelong PE [LPE] in 94 and acquired PE [APE] in 32) who presented to the urology outpatient clinic between April 2016 and January 2023 and 92 healthy men as a control group. The diagnosis of PE was based on the criteria defined by the International Society for Sexual Medicine.

Circadian preference, describes biological and behavioural characteristics that influence the ability to plan daily activities according to optimal waking times. It is divided into three main categories: morning, evening and intermediate. In particular, the evening chronotype is associated with conditions such as Attention Deficit Hyperactivity Disorder (ADHD) and Post Traumatic Stress Disorder (PTSD).

The present study provides indications and underlying drivers of wave-induced transport and retention potential of microplastic particles (MP) in marine vegetation canopies having different densities. The anthropogenic occurrence of MP in coastal waters is well documented in the recent literature. It is acknowledged that coastal vegetation can serve as a sink for MP due to its energy dissipating features, which can mimic a novel ecosystem service.

Objective: Acne vulgaris, a prevalent chronic condition among adolescents, significantly impacts patients' quality of life and self-esteem. Our aim was to investigate whether how adolescents perceive their family emotional atmosphere has an impact on their acne severity, quality of life, and self-esteem.

Materials And Methods: This study included 118 patients with acne vulgaris who completed various assessments, including a sociodemographic data form, the Acne Quality of Life Scale, the Hospital Anxiety and Depression Scale, the Shortened Level of Expressed Emotion Scale (SLEES) and, the Rosenberg Self-Esteem Scale.

We have investigated the electronic and finite temperature magnetic properties of germanium carbide (GeC) and ferromagnetic chromium nitride (CrN) heterobilayers by using first-principles calculations based on density functional theory with Hubbard U correction and an effective anisotropic Heisenberg spin model. The dynamical stability of different stacking formations of heterobilayers is ensured by considering the phonon spectra. All the stacking patterns show half-metallicity with an out-of-plane easy-axis ferromagnetic ground state.

Background: Research on the use of tissue interposition flaps (TIFs) in vesicovaginal fistulae (VVF) repair is a broad area where a very wide range of natural and synthetic materials have been used. The occurrence of VVF is also diverse in the social and clinical settings, resulting in a parallel heterogeneity in the published literature on its treatment. The use of synthetic and autologous TIFs in VVF repair is not yet standardized with a lack of the most efficacious type and technique of the TIF.

Incipient motion conditions for 57 regular (spheres, cylinders, disks, square plates, cubes, square prisms, rectangular prisms, tetrahedrons, and fibers) and eight irregular microplastic particle groups, having various sizes and densities, are investigated in a circular flume. The present data set is combined with additional data from the literature and systematically analyzed. A new framework is developed for predicting incipient motion conditions for foreign particles, accounting for variations in static friction, hydraulic roughness, and hiding-exposure effects.
