Efficacy and Safety of CT-P13 as First- and Second-Line Treatment in Patients with Ankylosing Spondylitis.

CT-P13 is a biosimilar version of infliximab, a monoclonal antibody. In individuals with ankylosing spondylitis (AS), CT-P13 has been shown to be effective and to have a well-tolerated safety profile. The aim of this study was to evaluate the long-term drug persistence, safety, and efficacy of infliximab biosimilar CT-P13 in patients with AS undergoing first-line (1st-line) and later (≥2nd-line) treatment in clinical practice.

Evaluation of liver parenchyma with shear wave elastography in patients with rheumatoid arthritis receiving disease-modifying antirheumatic drug therapy.

Background: Methotrexate (MTX) and leflunomide (LEF) play fundamental roles in rheumatoid arthritis (RA) treatment and require proper monitoring of side effects. Concerns about MTX/LEF-related liver fibrosis (LF) in patients with RA remain unclear. This study investigated liver stiffness using two-dimensional shear wave elastography (2D-SWE) in RA patients undergoing disease-modifying antirheumatic drug (DMARD) therapy.

Patients And Methods: A total of 811 AS patients registered in the TURKBIO registry database between 2011 and 2019 were categorized according to their age at the time of entry into the registry and assigned to one of two groups: young patients, defined as <60 years of age (n=610), and those aged ≥60 years (n=201) were recorded as elderly patients. Demographic, clinical, and laboratory characteristics, along with disease activity markers and other follow-up parameters, as well as current and prior treatments, were electronically recorded during each visit using open-source software.

Influence of point mutations on PR65 conformational adaptability: Insights from molecular simulations and nanoaperture optical tweezers.

PR65 is the HEAT repeat scaffold subunit of the heterotrimeric protein phosphatase 2A (PP2A) and an archetypal tandem repeat protein. Its conformational mechanics plays a crucial role in PP2A function by opening/closing substrate binding/catalysis interface. Using in silico saturation mutagenesis, we identified PR65 "hinge" residues whose substitutions could alter its conformational adaptability and thereby PP2A function, and selected six mutations that were verified to be expressed and soluble.

The role of fatty acids in patients with Behçet's disease and their association with thrombosis.

Behçet's disease (BD) is a systemic disease with unknown etiopathogenesis and varying disease presentations. Fatty acids (FA) are essential biological compounds that are involved in complex metabolic pathways. They may contribute to inflammation and endothelial dysfunction by participating in many signaling pathways.

The mechanism and energetics of the dynein priming stroke.

Dyneins are an AAA+ motor responsible for motility and force generation toward the minus end of microtubules. Dynein motility is powered by nucleotide-dependent transitions of its linker domain, which transitions between straight (post-powerstroke) and bent (pre-powerstroke) conformations. To understand the dynamics and energetics of the linker, we performed all-atom molecular dynamics simulations of human dynein-2 primed for its power stroke.

Spousal support and dyadic adjustment in the early postpartum period.

In the study, we aimed to investigate the effects of perceived spousal support and dyadic adjustment on the psychological well-being of women in the early postpartum period. This descriptive and correlational study consisted of 367 women giving birth in the postpartum department between 15th July and 31st October 2022. The data were collected using the Personal Information Form, the Perceived Spousal Support Among Women in Early Postpartum Period (PSSAWEPP), the Revised Dyadic Adjustment Scale (RDAS), and the Psychological Well-Being Scale (PWBS).

Influence of Point Mutations on PR65 Conformational Adaptability: Insights from Nanoaperture Optical Tweezer Experiments and Molecular Simulations.

PR65 is the HEAT-repeat scaffold subunit of the heterotrimeric protein phosphatase 2A (PP2A) and an archetypal tandem-repeat protein, forming a spring-like architecture. PR65 conformational mechanics play a crucial role in PP2A function by opening/closing the substrate-binding/catalysis interface. Using saturation mutagenesis we identified "hinge" residues of PR65, whose substitutions are predicted to restrict its conformational adaptability and thereby disrupt PP2A function.

Altered kynurenine pathway metabolism and association with disease activity in patients with systemic lupus.

Systemic lupus erythematosus (SLE) is an autoimmune disease accompanied by increased release of proinflammatory cytokines that are known to activate the indoleamine 2,3-dioxygenase (IDO-1) enzyme, which catalyzes the rate-limiting step of the kynurenine pathway (KP). This study aimed to measure KP metabolite levels in patients with SLE and investigate the relationship between disease activity, clinical findings, and KP. The study included 100 patients with SLE and 100 healthy controls.

The investigation of diverse physiological and therapeutic impact of cellular-based products derived from human cumulus cells.

Particular somatic cells, namely cumulus cells (CCs) that support the oocyte maturation, fertility, and viability by providing the nutrients and energy to the oocyte envelop the mammalian oocyte. In this study, discarded human cumulus tissues were used to reveal the value of hyaluronic acid-rich CCs on several cellular events, including differentiation. Conditioned media, recovered from the primary culture of CCs, were introduced to the human nucleus pulposus cells (hNPCs) which were functionally distorted because of the loss of chondrogenecity.

Impaired kynurenine metabolism in patients with primary Sjögren's syndrome.

Objectives: Primary Sjögren's syndrome (pSS) is an autoinflammatory disease characterized by inflammation of the exocrine glands.

Assessment of serum neopterin and calprotectin as biomarkers for subclinical inflammation in patients with familial Mediterranean fever.

Background: Familial Mediterranean fever (FMF) is the most common autoinflammatory disease characterized by short, repeated, and self-limiting attacks of fever and serositis. Subclinical inflammation can persist in the periods with no symptoms and result in amyloidosis even with colchicine treatment. Neopterin and calprotectin have been considered essential players in inflammation and immune response.
