Different Roles Of Endothelial Cell-Derived Fibronectin And Plasma Fibronectin In Endothelial Dysfunction, Xiaoxin Luo, Weixiong Jian Dec 2023

Different Roles Of Endothelial Cell-Derived Fibronectin And Plasma Fibronectin In Endothelial Dysfunction, Xiaoxin Luo, Weixiong Jian

Turkish Journal of Medical Sciences

MDABackground/ aim: Atherosclerosis is significantly influenced by endothelial cell activation and dysfunction. Studies have demonstrated the substantial presence of fibronectin (Fn) within atherosclerotic plaques, promoting endothelial inflammation and activation. However, cellular Fn (cFn) secreted by various cell types, including endothelial cells and smooth muscle cells, and plasma Fn (pFn) produced by hepatocytes. They are distinct forms of Fn that differ in both structure and function. The specific contribution of different types of Fn in promoting endothelial cell activation and dysfunction remain uncertain. Therefore, this study aimed to investigate the respective roles of pFn and endothelial cell-derived Fn (FnEC) in promoting …

The Role Of Superb Microvascular Imaging In Detecting Low-Grade Inflammation Among Adults And Those With Chronic Kidney Disease: A Preliminary Study, Alaaddi̇n Nayman, Nusret Seher, Mehmet Öztürk, Hali̇l Özer, Gülperi̇ Çeli̇k

Turkish Journal of Medical Sciences

Background/aim: Pathophysiologic changes associated with chronic inflammation occur with aging and more prominently in patients with chronic kidney disease (CKD), and an association between chronic inflammation and muscle wasting has been identified. The microcirculation is extremely sensitive to the inflammatory process and actively participates in it. In a healthy adult, angiogenesis is a strictly controlled and rare occurrence. However, aberrant angiogenesis and the development of new tiny blood vessels are known in chronic inflammatory diseases. Superb microvascular imaging (SMI) is a noninvasive technique that can evaluate tiny vessels with low blood flow and provide quantitative data. Our goal was to …

Hidden Threat In Familial Mediterranean Fever: Subclinical Inflammation, Oxidative Stress And Their Relationship With Vitamin D Status, Mhd Boshr Alesh, Di̇dem Barlak Keti̇, Ayşenur Paç Kisaarslan, Sabahatti̇n Muhtaroğlu, Sema Nur Taşkin Jan 2022

Hidden Threat In Familial Mediterranean Fever: Subclinical Inflammation, Oxidative Stress And Their Relationship With Vitamin D Status, Mhd Boshr Alesh, Di̇dem Barlak Keti̇, Ayşenur Paç Kisaarslan, Sabahatti̇n Muhtaroğlu, Sema Nur Taşkin

Turkish Journal of Medical Sciences

Background/aim: Vitamin D levels have been investigated in children with familial Mediterranean fever (FMF), but the relationship between vitamin D status and inflammation/oxidative stress indicators could not be clearly demonstrated. This study aimed to investi- gate the relationship between subclinical inflammation/oxidative stress and vitamin D status in children with FMF during an attack-free period. Materials and methods: In the cross-sectional study, ninety children with FMF in the attack-free period and 30 healthy children were included. Patients were grouped according to their vitamin D status (< 20, 20-29, and 30-100 ng/mL). The groups were compared in terms of pentraxin 3 (PTX-3), total oxidant status (TOS), and total antioxidant status (TAS). Multivariable linear regression analysis was performed to identify factors associated with vitamin D status. Results: PTX-3 levels were significantly higher in patients with vitamin D insufficiency (20-29 ng/mL) than in the group with vitamin D sufficient (30-100 ng/mL). Patients with vitamin D deficiency (< 20 ng/mL) had higher TOS. A strong negative correlation was ob- served between vitamin D levels and TOS (p = 0.003). Subclinical inflammation (PTX-3 ≥ 0.640) and high TOS levels were negatively associated with vitamin D levels. Conclusion: Subclinical inflammation and oxidative stress were negatively associated with vitamin D levels in patients with FMF dur- ing an attack-free period. Sufficient vitamin D levels are important in fighting subclinical inflammation and oxidative stress in children with FMF.

Turkish Journal of Medical Sciences

Background/aim: Anti IL-1 therapy is useful in suppressing attacks in FMF patients with colchicine resistance, however, it is not certain whether subclinical inflammation can sufficiently be inhibited with anti-IL-1 therapy in FMF patients with amyloidosis. Materials and methods: Forty-six FMF patients receiving anti-interleukin-1 therapy and 36 healthy control patients were compared in terms of laboratory parameters. Also, FMF patients were further divided into two groups; those with amyloidosis and those without it, and these subgroups were compared to each other in terms of clinical and laboratory findings. Results: In comparison between the FMF and healthy control groups, erythrocyte sedimentation rate …

Turkish Journal of Medical Sciences

In the Wuhan Province of China, in December 2019, the novel coronavirus 2019 (COVID-19) has caused a severe involvement of the lower respiratory tract leading to an acute respiratory syndrome. Subsequently, coronavirus 2 (SARS-CoV-2) provoked a pandemic which is considered a life-threatening disease. The SARS-CoV-2, a family member of betacoronaviruses, possesses singlestranded positive-sense RNA with typical structural proteins, involving the envelope, membrane, nucleocapsid and spike proteins that are responsible for the viral infectivity, and nonstructural proteins. The effectual host immune response including innate and adaptive immunity against SARS-Cov-2 seems crucial to control and resolve the viral infection. However, the severity …

Background/aim: Abnormal immune response occurs in individuals who have alleles associated with innate and adaptive immune mechanisms that predispose to inflammatory bowel disease (IBD). Interleukin-1 receptor-associated kinase 4 (IRAK-4) involved in the pathway produces cytokines that initiate and maintain inflammation through Toll-like receptors and interleukin-1 receptors on the membranes of innate immune cells are stimulated with antigens. It was aimed to investigate whether IRAK-4 rs3794262 and rs4251481 polymorphisms predispose to IBD and the possible effects of these polymorphisms by examining these gene polymorphisms with the clinic and prognostic parameters of IBD.Material and methods: Real-time PCR technique was used to detect …

Background/aim: Multipotent mesenchymal stem cells (MSCs) have been investigated in autoimmune diseases such as rheumatoid arthritis (RA) due to their immunomodulatory and regenerative properties. In this study, their immunosuppressive effects on peripheral blood mononuclear cells (PBMC) of RA patients were studied.Materials and methods: Dental follicle stem cells (DFSCs) were isolated from follicle tissue in the orofacial region. Characterization and multipotency analyses were performed. Lymphocytes were isolated from peripheral venous blood of RA patients (n = 5) and healthy individuals (n = 5). DFSCs were preincubated with IFN-γ for 48 h. PBMCs of RA patients and healthy individuals were separately cultured …

Background/Aim: Cisplatin is a highly effective chemotherapeutic agent used in the treatment of solid organ cancers. Besides its chemotherapeutic effectiveness, cisplatin administration is associated with numerous side effects. Of those, the most clinically significant and common effect is nephrotoxicity. Recent studies reported that oxidative stress and inflammation are probably the most important mechanisms that contribute to the nephrotoxicity. N-acetylcysteine (NAC) is an antioxidant and antiinflammatory agent. In the present study, the effects of NAC on cisplatin-induced nephrotoxicity were investigated. Materials and methods: Rats were divided into four groups each including eight rats: CONT, NAC-250, CP, and CP+NAC. Rats in experimental …
