Experimental Vitamin D Deficiency in Rats: Clinical Chemistry, Histopathological, and Immunological Evaluation.

Background: Vitamin D deficiency is a significant global health concern. Experimental models are essential to elucidate the biochemical, histopathological, and immunological consequences of this deficiency. This study established a vitamin D deficiency rat model to mimic insufficient vitamin D intake and examine the resulting health impacts, particularly on liver, kidney, and immune functions.

Morphological and biomechanical effects of vitamin K2 on fracture healing: An animal study on the rat tibia fracture model.

Objective: The aim of this study was to evaluate the effects of vitamin K2 on fracture healing.

Methods: Twenty-four 6-week-old male Wistar albino rats that had open tibia fractures induced were included in this study. They were divided into 2 groups of 12, a group that had vitamin K2 administered over 30 consecutive days and a control group.

Adaptation of Clinical Laboratories to COVID 19 Pandemic: Changes in Test Panels, Overcoming Problems and Preparation Suggestions for Future Pandemics Adaptation of Clinical Laboratories to COVID 19 Pandemic.

Background: For Coronavirus Disease 2019 (Covid-19) infection, clinical laboratories provide essential contributions in the diagnosis of infection, stage prognostication, and evaluation of disease severity. We aimed to show laboratory problems including changes of test numbers, changes of test panels, and differences of preanalytical errors during Covid-19 pandemic and, in the current study, we also intended to give solutions for the obstacles to guide other possible pandemics.

Methods: Our study was based on data between January 10, 2020, and May 10, 2020.

Can Cytokines be used as an Activation Marker in Rheumatoid Arthritis?

Aims: The etiopathogenesis of Rheumatoid Arthritis (RA) is not clearly understood. However, the role of the cytokines play an important part in this mechanism. We aimed to bring a new approach to the concept of 'remission' in patients with RA.

The Effects of Initial Procalcitonin Levels on Mortality Rates in Geriatric Patients Undergoing Surgery.

Introduction The aim of the current study is to investigate the relationship between mortality rate in geriatric patients undergoing surgery with preoperative serum levels of procalcitonin, C-reactive protein, and erythrocyte sedimentation rate. Methods This was a single-center retrospective study, including three groups with 101 patients, who are older than 65 years of age. A retrospective investigation was carried out from the laboratory information system for all groups from January to December 2018.

Therapeutic Drug Monitoring Characteristics in a Tertiary University Hospital in 2019.

Introduction Therapeutic drug monitoring (TDM) is defined as measuring drug concentration in a biological sample to optimize pharmacotherapy. This study aims to evaluate TDM requests in a tertiary university hospital retrospectively. Materials and methods TDM requests were evaluated retrospectively for lithium, valproic acid, carbamazepine, and digoxin in 2019.
