Evaluation of the Trachea and Bronchi in COVID-19 Patients Using the 3-dimensional Reconstruction Method.

Objective: To evaluate changes in the trachea and bronchi of COVID-19 patients using the 3-dimensional reconstruction images obtained from chest CT (computed tomography) scans.

Study Design: An observational study. Place and Duration of the Study: Departments of Anatomy and Radiology, Faculty of Medicine, Lokman Hekim University, Ankara, Turkey, between March 2021 and January 2022.

Optimal screw positioning in cervical pedicles to avoid complications.

Background: Cervical instability can be caused by a variety of factors, including trauma, tumors, or infection. The cervical transpedicular screw (CPS) is one of the most modern procedures for treating cervical instability. Despite the fact that numerous innovative techniques for CPS have been proposed, the appropriate screw entry points and screw directions have yet to be thoroughly established.

Investigation of the nerve distribution pattern of leg muscles in rat.

Information about the distribution of intramuscular nerve fibres within the skeletal muscles will enhance the understanding of their morphological structure and functions. This study was designed to examine the entire intramuscular nerve distribution pattern in rat leg muscles. The tibialis cranialis, tibialis caudalis, extensor digitorum longus, flexor digitorum longus, gastrocnemius, peroneus longus and brevis muscles were dissected from origo and insertion points under a surgical microscope in seven rats.

The effect of valproic acid and oxcarbazepine on the distribution of adhesion molecules in embryo implantation.

This study was intended to investigate the effect of valproate (VPA) and oxcarbazepine (OXC) on embryo implantation in terms of extracellular matrix protein distribution. Thirty female rats (Wistar albino) were assigned to three groups of 10 animals each. Group 1 was administered two doses of saline solution, group 2, two doses of VPA at 300 mg/kg/day and group 3, two doses of OXC at 100mg/kg/day, for a period of 3 months.

Methylphenidate has dose-dependent negative effects on rat spermatogenesis: decreased round spermatids and testicular weight and increased p53 expression and apoptosis.

In the present study, we aimed to evaluate the possible effects of methylphenidate on rat testes. Forty-two Wistar rats were randomly distributed into three experimental groups of 14 rats each. For 90 days, each group via gavage received the following: group 1 = tap water (control group), group 2 = 5 mg/kg/day of ritalin (methylphenidate, MPH), and group 3 = 10 mg/kg/day of ritalin.

Effects of chronic treatment with valproate and oxcarbazepine on testicular development in rats.

Purpose: The aim of this study was to examine the potential effects of valproate (VPA) and oxcarbazepine (OXC) on testicular development in rats.

Methods: Forty-two Wistar rats were randomly divided into three groups of 14 rats each. Each group received the following via gavage over 90 days: group 1, tap water (control group); group 2, VPA (300mg/kg/day); group 3, OXC (100mg/kg/day).

The prevalence and effects of Pectus Excavatum and Pectus Carinatum on the respiratory function in children between 7-14 years old.

The study involved 1342 primary school students aged 7-14 years who applied to Ankara, a primary care center for general health check-up between 2006 and 2007. Forty-three students, 35 of whom had PE and 8 of whom had PC, were subjected to thorax measurement. All 43 students underwent pulmonary function tests (PFT).

Is there any possible genotoxic effect in exfoliated bladder cells of rat under the exposure of 1800 MHz GSM-like modulated radio frequency radiation (RFR)?

People are exposed to many carcinogenic and mutagenic chemicals in their everyday lives. These include antineoplastic drugs, Polycyclic aromatic hydrocarbons (PAH)s, aromatic amines, nitrosamines, metals, and electromagnetic radiation. Based on the state of knowledge acquired during the last 50 years of research on possible biological effects of electromagnetic fields (EMF), the majority of the scientific community is convinced that exposure to EMF below the existing security limits does not cause a risk to the health of the general public.
