Introduction: Sialorrhea may be a consequence of severe acquired brain injury (ABI). Salivary gland botulinum neurotoxin (SG-BoNT) injections can reduce saliva production, but there is limited evidence for their use in ABI.We reviewed the effectiveness, impact on chest infection frequency, and safety of SG-BoNT for sialorrhea in a cohort of patients with severe ABI.

This article investigates cross-cultural differences in analytic/holistic cognitive styles among participants from 11 countries: Armenia, Australia, Brazil, Bulgaria, Czechia, Germany, Ghana, Philippines, Slovakia, Taiwan, and Türkiye. Using a preregistered design, 993 university students were assessed with three perceptual tasks based on Navon's hierarchical figures and Gottschaldt's embedded figures. Analytic and holistic cognitive styles were estimated using reaction time modeling, specifically a Bayesian four-parameter shifted Wald distribution and a hierarchical linear ballistic accumulator model.

Shaping the ear cartilage and preserving the shape are important and quite difficult. The aim of this study was to demonstrate the effectiveness of the Wharton's jelly-derived stem cell-assisted electromechanical reshaping method in a rabbit ear cartilage defect model and to compare it with surgical reshaping.For the purpose of 25 × 4-mm cartilage defect reconstruction, 48 rabbit ears were divided into 2 main groups according to the shaping method, and these main groups were divided into 3 subgroups according to stem cell injection: control, sham, and stem cell.

Objectives: This study aimed to explore whether using sonic irrigant activation during endodontic treatment favors periradicular repair in teeth with apical periodontitis.

Materials & Methods: One clinician treated 140 posterior (either premolar or molar) asymptomatic teeth with periapical lesions: 70 were randomly assigned to the sonic activation with EndoActivator (EA) group, and 70 were treated by conventional needle irrigation (CNI). Both groups underwent chemomechanical root canal preparation using 35/04 diameter rotary files and 2.

Managing locally advanced, or metastatic radioactive iodine-refractory differentiated thyroid cancers (RAIR-DTC) poses substantial challenges, with few available treatment options. The aim of this study was to evaluate clinical outcomes of patients receiving sorafenib as first line treatment. In addition, prognostic markers affecting progression-free survival (PFS) were identified.

Objective: To evaluate the efficacy of the symptoms of the Lower Urinary Tract Dysfunction Research Network Symptom Index-29 (LURN SI-29) questionnaire in assessing alpha-blocker treatment response in patients with lower urinary tract symptoms (LUTS).

Methods: This prospective, non-randomized, multicentre trial included males with LUTS who visited urology outpatient clinics between January and April 2023. The most employed LUTS questionnaire is the International Prostate Symptom Score (IPSS), while the LURN SI-29 was also utilized.

Aim: This study aims to retrospectively evaluate the incidence and stage of oral mucositis in patients undergoing hematopoietic stem cell transplantation.

Methods: A total of 102 patient records of patients hospitalized between 2014 and 2019 in the adult hematopoietic stem cell transplantation clinic of a tertiary university hospital in Turkey were evaluated. Data were collected through a retrospective evaluation of patient records.

Hydrolysis is the most critical rate-limiting step in the anaerobic digestion (AD) process for most types of substrates. The organic fraction of municipal solid waste (OFMSW) is a rich source for the AD process because of its high degradability. In this study, electrohydrolysis pretreatment was investigated for the OFMSW to overcome the rate-limiting step of hydrolysis.

Article Synopsis
  • Fluid overload (FO) in critically ill children is linked to increased morbidity and mortality, and while CRRT is used to manage FO, its impact on children's heart function is not well understood.* -
  • This study analyzed 17 children receiving CRRT, finding that those with FO greater than 15% had significantly higher systemic vascular resistance and lower cardiac indices, though heart rate and mean arterial pressure remained stable.* -
  • The findings suggest that FO negatively affects the hemodynamic profile in children on CRRT, and highlight the potential of using electrocardiometry to study these effects further.*

In metaproteomics studies, constructing a reference protein sequence database that is both comprehensive and not overly large is critical for the peptide identification step. Therefore, the availability of well-curated reference databases and tools for custom database construction is essential to enhance the performance of metaproteomics analyses. In this review, we first provide an overview of metaproteomics by presenting a concise historical background, outlining a typical experimental and bioinformatics workflow, emphasizing the crucial step of constructing a protein sequence database for metaproteomics.

Background: Indoleamine 2,3-Dioxygenase 1 (IDO1)-mediated tryptophan degradation, which is the rate-limiting enzyme of tryptophan/kynurenine pathway, may cause immune suppression in the tumor microenvironment, while potentiating proliferative and metastatic activity in the tumor focus, Phase studies of IDO1 inhibitors are ongoing, and our study aims to evaluate the potential contribution of IDO1 gene expression to the tryptophan/kynurenine pathway in tumor and tumor microenvironment foci in gastric cancer (GC) on a clinicopathological axis, METHOD: In the case-control study design, the determination of tryptophan and its metabolites in the serum of 51 GC and 49 healthy controls was made using High Pressure Liquid Chromatography-Fluorescence Detector (HPLC-FD). IDO1 expression in a total of 102 tissues with tumor and tumor microenvironment was detected by quantitative PCR (q-PCR).

Results: In gastric tumors, 3,25-fold decreased expression of IDO1 was detected according to the tumor microenvironment (p=0,05), IDO1 expression was found to be more than 2 times higher in signet ring cell carcinoma (SRCC) and poorly differentiated tumors without distant organ metastasis (p<0,05), In GC, tryptophan level was found to be 1,6 times lower than in control (AUC:0889; cut off≤21,57; p<0001), Low tryptophan level was found in advanced tumor stage compared to early stage and in the presence of perineural invasion compared to its absence (p<0,05) The level of kynurenine was found to be approximately 1,8 times lower in SRCC (p=0,04), CONCLUSION: Increased tryptophan accumulation in the gastric tumor and its microenvironment, when catabolized via IDO1, exhibits histological type, tumor differentiation, and metastasis-promoting effects more prominently in aggressive subtypes such as SRCC.

Article Synopsis
  • The study investigates the prognostic factors for C3 glomerulopathy (C3G), focusing on the total chronicity score (TCS) derived from a new histological index (C3G-HI).
  • 74 patients from 20 medical centers were analyzed to determine factors affecting kidney health outcomes, with a particular emphasis on hemoglobin levels and their correlation with patient survival and kidney function.
  • Results indicated that low hemoglobin levels were linked to worse outcomes in C3G patients, and a TCS of 4 or higher correlated with significantly lower kidney survival rates over three years.
