Exploring S100A8/A9, neopterin, and MMP3 in familial Mediterranean fever.

Familial Mediterranean fever (FMF) is characterized by inflammatory attacks due to overactivation of pyrin inflammasome. This study aimed to investigate the reliability of S100A8/A9, neopterin, and matrix metalloproteinase 3 (MMP3) at monitoring subclinical inflammation and disease activity, and at differentiating FMF attacks from appendicitis, the most common misdiagnosis among FMF patients. Blood samples (n = 75), comprising from FMF patients during an attack (n = 20), the same FMF patients during the attack-free period (n = 14), patients with appendicitis (n = 24), and healthy volunteers (n = 17) were obtained.

The role of geraniol on hepatic ischemia-reperfusion injury model in rats.

Background: Hepatic ischemia/reperfusion (I/R) injury is a significant clinical condition that can arise during liver resections, trauma, and shock. Geraniol, an isoterpene molecule commonly found in nature, possesses antioxidant and hepatoprotective properties. This study investigates the impact of geraniol on hepatic damage by inducing experimental liver I/R injury in rats.

Matrix Metalloproteinases/Tissue Inhibitors of Metalloproteinases Ratio: A Biomarker of Bone Resorption in Geriatric Osteoporosis?

Background: Matrix metalloproteinases (MMPs) play an important role in bone resorption and are regulated by tissue inhibitors of metalloproteinases (TIMPs). We investigated the use of MMP2/TIMP2 and MMP9/TIMP1 ratios as biomarkers of bone resorption in geriatric osteoporosis and evaluated the relationship between osteoporosis and geriatric syndromes.

Methods: This analytical cross-sectional study involved 87 patients (41 with osteoporosis) treated at the geriatric outpatient clinic of a university hospital.

Assessment of the role of neutrophil extracellular traps in SARS-CoV-2 pneumonia.

Background: Abnormal neutrophil extracellular traps are associated with lung diseases, thrombosis, increased mucosal secretion in the airways. The aim of this study is to evaluate the possible place of the most specific NETosis marker Cit-H3 protein in diagnostic algorithms by revealing its relationship with the severity, mortality and prognosis of SARS-CoV-2 pneumonia.

Patients And Methods: Patients (n = 78) who applied to the Emergency Department between March 11, 2020 and June 10, 2020, with positive SARS-CoV-2 polymerase chain reaction (PCR) test and lung involvement were included in the prospective study.

Relationship Between Carotid Intima-Media Thickness and Osteoporosis in Type 2 Diabetic Patients: Cross-Sectional Study in the Third-Level Center.

Although atherosclerosis and osteoporosis (OP) are seen in elderly patients, it is still a matter of research whether there is an age-independent relationship between them. In our study, we planned to investigate the relationship between carotid intima-media thickness (CIMT), OP, and bone turnover parameters in patients with type 2 diabetes mellitus (DM2) of both sexes. A total of 69 patients and 40 healthy volunteers with chronic diseases such as DM2, hypertension, hyperlipidemia, and OP.

The clinical significance of circulating miR-21, miR-142, miR-143, and miR-146a in patients with prostate cancer.

Background: Prostate cancer (PCa) is the most common type of solid tissue cancer among men in western countries. In this study, we determined the levels of circulating miR-21, miR-142, miR-143, miR-146a, and RNU 44 levels as controls for early diagnosis of PCa.

Methods: The circulating miRNA levels in peripheral blood samples from 43 localized PCa patients, 12 metastatic PCa (MET) patients, and a control group of, 42 benign prostate hyperplasia (BPH) patients with a total of 97 volunteers were determined the by PCR method.

ACE2 and ANGII levels in patients with COVID-19 based on thoracic tomography findings and PCR test results.

Introduction: Reverse transcriptase polymerase chain reaction tests and thoracic tomography have been widely employed in the diagnosis of the disease, but doubts about their sensitivity still persist. Also there are controversial results about ACE2 and AngII levels according to the severity of disease. In this study, we aimed to analyze the ACE2 and AngII levels in patients with suspected COVID-19 based on polymerase chain reaction test results and thoracic tomography findings and to examine their relationship with disease severity.

The Effects of Diabetic Polyneuropathy and Autonomic Neuropathy on Bone Turnover.

The effect of diabetic polyneuropathy (DPN) and autonomic neuropathy (AN) on bone turnover in type 2 diabetes mellitus (DM) is uncertain due to the lack of data. In this study, we tried to determine the effect of DPN and AN on bone metabolism. The study included patients with type 2 DM (aged 18-80 years) and age-matched healthy individuals who presented to the Departments of Metabolism and Diabetes, Geriatrics, and General Internal Medicine, Cerrahpaşa Medical School, Istanbul University.

Association of FGF-19 and FGF-21 levels with primary sarcopenia.

Aim: Serum fibroblast growth factor (FGF)-19 and FGF-21 levels have been reported to be associated with muscle hemostasis. This study aims to explore the relationship between the levels of these markers and sarcopenia.

Methods: In our single-center, cross-sectional study, patients over 65 years old presenting to the geriatric outpatient clinic were included.

Is Waist-height Ratio Associated with Thyroid Antibody Levels in Children with Obesity?

Objective: Obesity is known to affect thyroid function. Recently, waist-height ratio (WHtR) has been considered as a useful marker of subclinical hypothyroidism in obese cases, but its relation with thyroid autoimmunity still remains unclear. We evaluated the effect of body fat mass, WHtR, and metabolic parameters on thyroid autoantibody levels in children with obesity.

Soluble TREM-1 Levels in Familial Mediterranean Fever Related AA-Amyloidosis.

: Triggering Receptor Expressed on Myeloid cells-1 (TREM-1) is a monocyte and neutrophil receptor functioning in innate immunity. TREM-1 activity has been studied in various autoimmune diseases such as RA and SLE but there is no data in autoinflammatory pathologies. We studied soluble TREM-1 (sTREM-1) activity in Familial Mediterranean Fever (FMF) cases to evaluate the clinical role of TREM-1 in amyloidosis.

Effects of atorvastatin therapy on hypercholesterolemic rabbits with respect to oxidative stress, nitric oxide pathway and homocysteine.

Hypercholesterolemia is characterized with changes in lipid profile, nitric oxide pathway and oxidative stress markers. This study is designed to evaluate the effects of hypercholesterolemic diet and atorvastatin therapy on oxidative stress, lipid peroxide and thiobarbituric acid reactive substances (TBARS), NO pathway markers, nitric oxide(NO) and asymmetric dimethylarginine (ADMA), homocysteine, and paraoxonase activity (PON1) in rabbits. Twenty rabbits fed with high-cholesterol diet for 8 weeks were randomly divided into 2 groups on the fourth week of the hypercholesterolemic diet.
