Boron-Doped Nano Hydroxyapatite Grafts for Bone Regeneration in Rat Mandibular Defects.

The aim of this study was to evaluate the potential effects of boron-doped nano hydroxyapatite grafts on craniofacial bone regeneration in critical bone defects in the mandibular corpus of rats, in terms of scintigraphic and histopathological aspects. Forty Wistar albino rats, with an average weight of 200-220 g, aged 16-18 weeks, and all male, were used in the study. The rats were randomly assigned to five groups, each containing 8 rats, as follows: group C1 (no procedure applied to the mandible), group C2 (surgical defect created in the mandible but no treatment applied), group nHA (nano hydroxyapatite applied to the surgical defect area), group nHA + B1 (nano hydroxyapatite + 1% boron applied to the surgical defect area), and group nHA + B2 (nano hydroxyapatite + 2% boron applied to the surgical defect area).

Comprehensive evaluation of deep neck infections: A retrospective analysis of 111 cases.

Purpose: Our study will analyze patients' clinical characteristics, treatment strategies, and complications with deep neck infection (DNI) using their medical records for five years.

Methods: The present study included 111 patients diagnosed with DNI in our clinic between January 2018 and March 2023. The patients' complaints at admission, sociodemographic characteristics, season of diagnosis, findings from laboratory tests, radiological imaging performed at the time of first diagnosis, abscess localization, medical and surgical treatment methods used, and complications developing during follow-up were retrospectively examined.

Detection and Classification of Diabetic Macular Edema with a Desktop-Based Code-Free Machine Learning Tool.

Objectives: To evaluate the effectiveness of the Lobe application, a machine learning (ML) tool that can be used on a personal computer without requiring coding expertise, in the recognition and classification of diabetic macular edema (DME) in spectral-domain optical coherence tomography (SD-OCT) scans.

Materials And Methods: A total of 695 cross-sectional SD-OCT images from 336 patients with DME and 200 OCT images of 200 healthy controls were included. Images with DME were classified into three main types: diffuse retinal edema (DRE), cystoid macular edema (CME), and cystoid macular degeneration (CMD).

What we learned from steroid therapy in the COVID-19 pandemic.

Background: The emergence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) caused a pandemic named coronavirus disease 2019 (COVID-19) that has become the greatest worldwide public health threat. Although different treatment recommendations are offered for COVID-19 infection, steroid treatment remains important.

Aim: We aimed to demonstrate the effect of pulse steroid therapy (PST) on inflammatory markers and patient outcomes in moderate/severe COVID-19 pneumonia.

The effects of transcutaneous auricular vagus nerve stimulation on visual memory performance and fatigue.

Objectives: This study aims to investigate the effects of transcutaneous auricular vagus nerve stimulation (taVNS) on visual memory performance and fatigue in healthy individuals.

Patients And Methods: Between April 10, 2022 and May 25, 2022, a total of 60 physical therapy and rehabilitation students (27 males, 33 females; mean age: 20.6±1.
