Relative age effects (RAEs) refer to all consequences of chronological age-based systems. The purpose of this study was to investigate the prevalence of RAEs among Turkish racket sports players. As a nationwide analysis, the present study extends beyond the typical investigations of elite-level popular sports by examining RAEs in racket sports players from the lowest grassroots level to the top and from children to veteran athletes.

Relative Age Effects (RAEs) have been widely reported trends in basketball participation, but research on the relationship between RAEs and competitive performance has been contradictory. We aimed to determine the magnitude of RAEs in elite youth basketball players and to analyze RAEs on key performance indicators (KPIs). We recorded and analyzed the incidence of early birthdates and the KPIs of 2487 youth basketball players (aged 16-19 years).

We analyzed the frequency of complications and survival rates in patients with autoimmune hepatitis (AIH) who underwent liver transplantation at a high-volume transplant center. Patients who underwent transplantation for AIH at the xxx University Liver Transplantation Institute between January 2002 and December 2021 were included. Patients with a confirmed diagnosis of AIH, without concomitant chronic liver disease, were included in the study.

Purpose: The aim of this study was to investigate the relationship between voxel-based dosimetric variables derived from Y-90 PET/MRI and hypertrophy observed in the left lobe after radioembolization and to investigate if there is any difference in hypertrophy induced by glass versus resin microspheres.

Methods: Voxel-based dosimetry-derived variables and their relationship with the change of the standardized future liver remnant (ΔFLR) was investigated with linear regression models. To compare and evaluate the discriminatory power of the dosimetric variables, ROC analyses were utilized.

Article Synopsis
  • * A total of 107 dogs were divided into treatment groups, and the serum levels of several trace elements, including magnesium and iron, were measured using advanced spectroscopy techniques.
  • * Results showed significant changes in serum magnesium and iron levels with longer treatment durations, indicating that the use of these heart medications could affect trace element levels in dogs with heart failure.

Background: Lichen striatus (LS) is a benign, mostly self-limiting dermatological condition, primarily affecting the skin, and sometimes the nails. It is characterised by the sudden onset of a band-like rash, typically following Blaschko lines. The exact cause of LS is not well established, but it is believed to be an abnormal immune response to the altered keratinocyte clone after a triggering event.

Acute pancreatitis (AP) is a clinical condition that arises acutely in the pancreas through various inflammatory pathways due to multiple causes. Turkish Society of Gastroenterology Pancreas Working Group developed comprehensive guidance statements regarding the management of AP that include its epidemiology, etiology, clinical presentation, diagnostic criteria, disease severity, treatment, prognosis, local and systemic complications. The statements were developed through literature review, deliberation, and consensus opinion.

Purpose: BUDA-cEPI has been shown to achieve high-quality, high-resolution diffusion magnetic resonance imaging (dMRI) with fast acquisition time, particularly when used in conjunction with S-LORAKS reconstruction. However, this comes at a cost of more complex reconstruction that is computationally prohibitive. In this work we develop rapid reconstruction pipeline for BUDA-cEPI to pave the way for its deployment in routine clinical and neuroscientific applications.

Article Synopsis
  • - This study investigates the protective effects of Lutein (L) against the harmful effects of the cancer drug Cisplatin (CS) on the brains of rats, using biochemical and histopathological tests.
  • - Lutein was administered orally, while Cisplatin was given via injection, and the results showed that Lutein reduced oxidative stress and improved antioxidant levels in the rats treated with both substances.
  • - Histopathological observations indicated that Lutein helped prevent brain damage associated with Cisplatin treatment, suggesting its potential as a protective agent in cancer therapy.

Breast cancer (BC) is the leading cause of cancer-related mortality among women, and hormone receptor (HR)-positive subtype makes up the majority of all cases. The standard of care in HR/HER2 metastatic BC (MBC) is endocrine therapy (ET) plus a CDK4/6 inhibitor (CDK4/6i). mutations could impair the clinical efficacy of the ETs.

Introduction: This study investigated wrist joint degeneration after curettage and PMMA treatment for giant cell bone tumours (GCBT) at the distal radius.

Methods: We performed a retrospective single-centre study, which included 23 patients with GCBT at distal radius treated with curettage and PMMA between 2001 and 2021. The progression of wrist joint degeneration was assessed through radiographic evidence, comparing the postoperative grade with both the preoperative grade and the grade of the contralateral wrist at the latest follow-up.

Background: Mitochondrial biogenesis (MB) induction has recently emerged as potential therapeutic approaches in kidney pathology and the mitochondria-targeted therapies should be investigated to improve treatment of animals with kidney diseases. This study aimed to investigate the effects of MB induction with sildenafil citrate on the cGMP/NO pathway, glomerular filtration, and reduction of kidney damage and fibrosis (TGF-β/SMAD pathway) in cats with acute on chronic kidney disease (ACKD). Thirty-three cats were divided into the non-azotemic (healthy) group (n:8) and the ACKD group (n:25), comprising different breeds, sexes, and ages.

Article Synopsis
  • The study examines how cats respond to bacterial versus viral infections, focusing on the inflammatory responses that play a key role in managing these infections.
  • It involved 75 cats divided into three groups: healthy controls, those with bacterial infections, and those with viral infections, analyzing various blood parameters.
  • Findings indicated that while some inflammatory markers were similar, certain markers like TGF-β were lower in viral infections, and WBC count and IL-6 levels were higher in bacterial infections, highlighting distinct response patterns that could aid in treatment strategies for feline diseases.

In this investigation, a novel environmentally friendly functionalized fluorescent Sp-TAB hybrid material was advanced for the sensitive detection of environmentally polluting Hg(II). The characterization of the synthesized fluorescent Sp-TAB hybrid material using SEM and EDX provided insights into morphological and structural changes in the material's pore structure, while XRD and FT-IR analyses revealed the impact of the prepared material at each stage. Optimal parameters such as temperature, contact time, and pH influencing Hg(II) ion detection were determined.
