Pulmonary fibrosis is a refractory entity with a progressive course and no effective therapeutic options. The purpose of this study was to investigate the potential involvement of both glabridin and dexamethasone (Dex) in inflammatory and fibrotic responses in a bleomycin (BLM)-induced pulmonary fibrosis model. The role of Ca-activated K channels (BK) in the anti-inflammatory effects of glabridin was also examined.

Low-grade malignant eccrine spiradenoma (spiradenocarcinoma) is a rare sweat gland tumor, which usually arises from a pre-existing benign eccrine spiradenoma. This paper presents the case of a 55-year-old male who had a lesion in his right elbow for 10 years. The microscopic examination revealed a well-demarcated, multilobulated tumor in the dermis and subcutis, which presented with many blood-filled vessels and extensive hemorrhage.

Avastin is a humanized recombinant monoclonal antibody used to treat cancer by targeting VEGF-A to inhibit angiogenesis. SIMAB054, an Avastin biosimilar candidate developed in this study, showed a different charge variant profile than its innovator. Thus, it is fractionated into acidic, main, and basic isoforms and collected physically by Cation Exchange Chromatography (CEX) for a comprehensive structural and functional analysis.

Nucleic acid aptamers are target-specific oligonucleotides selected from combinatorial libraries through an iterative in vitro screening process known as Systemic Evolution of Ligands by Exponential Enrichment (SELEX). In this report, the selection of bacteria differentiating ssDNA aptamer candidates from a combinatorial library through the whole-cell SELEX method was performed. The enriched SELEX pool was sequenced using Illumina Next-Generation Sequencing (NGS) technology and analyzed for the most abundant sequences using CLC Genomics Workbench.

Background: The All-on-four dental implant method is an implantology method designed to provide a comfortable prosthetic treatment option by avoiding advanced surgical procedures. This research aims to compare and evaluate the stress and tension values in conventional angled multiunit abutment-implant connection systems and monoblock dental implants used in the all-on-four procedure with finite element analysis.

Methods: Two master models were created by placing four implants connected to multiunit abutments (group A) in the interforaminal region of a completely edentulous mandible and four monoblock implants (group B) in the same region of another completely edentulous mandible.

Carbamazepine (CMZ) increases estrogen metabolism by inducing cytochrome P450 (CYP3A4). We investigated whether CMZ is protective against endometrial hyperplasia (EH). We used 32 female Wistar albino rats divided into four equal groups: the control group received drinking water, the estradiol valerate (EV) group was given EV, the CMZ group was given CMZ, and the EV + CMZ group was given both EV and CMZ.

The arterial revascularization procedure is still a challenging issue in Covid-19 associated limb ischemia. Herein we aimed to present a case of a 64 year-old woman with acute ischemic signs in upper extremity who was diagnosed as a probable Covid-19 case incidentally after admission. Although late admission and failed recurrent embolectomies lead to an eventful course, intra-arterial thrombolysis seemed to present a benefitable treatment option for our patient.

The aim of the current study was to investigate the pharmacological activity of glabridin on the isolated human saphenous vein (SV) and explore the underlying mechanisms. Samples of patients' SVs were removed during bypass surgery, and 4-mm lengths of the vessels were placed in Krebs solution at +4°C and hung in an isolated organ bath to assess their contraction/relaxation responses. The contraction/relaxation responses were recorded to observe if the cyclic guanosine monophosphate (cGMP)/protein kinase G (PKG) pathway mediates the relaxant effect of glabridin after treatment with blockers like ODQ (a guanylate cyclase inhibitor), KT5823 (a PKG inhibitor), isobutylmethylxanthine [IBMX, a phosphodiesterase (PDE) inhibitor], and cantharidin [Cant, a myosin light-chain phosphatase (MLCP) inhibitor].

The similarity between originator and biosimilar monoclonal antibody candidates are rigorously assessed based on primary, secondary, tertiary, quaternary structures, and biological functions. Minor differences in such parameters may alter target-binding, potency, efficacy, or half-life of the molecule. The charge heterogeneity analysis is a prerequisite for all biotherapeutics.

Pulmonary sequestration is defined as nonfunctioning lung tissue that is not in normal continuity with the tracheobronchial tree and that has a systemic arterial blood supply. Herein, we aimed to present a case of a 34-year-old male patient who had massive left-sided haemothorax on admission due to a giant intralobar pulmonary sequestration. An emergent repair was performed under cardiopulmonary bypass with axillofemoral cannulation.

Background: Postoperative atrial fibrillation (PoAF) is one of the most common complications to occur after open heart surgery. It has been shown that hypoalbuminemia accompanies some cardiovascular disorders. The present study evaluates the effects of pre-procedural albumin, blood urea nitrogen (BUN), and creatinine levels on PoAF.

Asthma is a disease characterized by spontaneous contraction of the airways in response to a wide variety of endogenous and exogenous stimuli. Many asthma models are used to mimic the human asthma model in the literature. In order to better understand the role of the cannabinoid (CB) 2 receptor in the ovalbumin (OVA)-induced asthma model, a combination of both selective CB2 agonist (AM1241) and antagonist (AM630) was used to improve inflammatory hypersensitivity and edema in rats.

Asthma is an inflammatory disease of the airways of the lungs, which is characterized by airflow obstruction and bronchospasms. Glabridin is a major flavonoid, especially found in root of Glycyrrhiza glabra, and has several pharmacological activities, including antioxidant and anti-inflammatory effects. The anti-asthmatic effect and possible mechanism of glabridin, however, have not been revealed so far.

Objectives: The aim of the present study was to investigate the effect of thymoquinone on ischemia/reperfusion (I/R) injury at 150 min or/and 24 h of reperfusion in male Wistar Rats.

Material And Methods: The therapeutic value of thymoquinone on cellular damage caused by reactive oxygene species or inflammatory processes during intestinal ischemia/reperfusion was investigated using pharmacological function studies on smooth muscle contractile responses of acetylcholine (Ach) and KCl, along with myeloperoxidase activity, malondialdehyhde, glutathione and cytokine levels such as tumor necrosis factor (TNF)-α and interleukin (IL)-1β in serum and ileum tissue of rats. Thymoquinone was administered at a dose of 50 mg/kg orally for three times: 30 min, 24 h and 48 h prior to the surgical procedure.

Inflammation, and the pain that accompanies it, is a natural response of the body. The licorice plant (Glycyrrhiza glabra) have demonstrated anti-inflammatory, anti-edematous, and anti-nociceptive effects of its extracts. The effective ingredient remains unidentified; however, one possibility is the unique isoflavone glabridin.

Background: The aim of the present study was to investigate the effect of resveratrol on cytokine levels and oxidative stress in intestinal ischemia/reperfusion (I/R) injuries.

Methods: To induce intestinal I/R, the superior mesenteric artery was occluded for 30 min and then reperfused for 150 min or 24 h. The therapeutic effects of resveratrol on the damage from intestinal I/R were investigated using an isolated organ bath, along with oxidant/antioxidant and inflammatory factors such as glutathione (GSH), malondialdehyde (MDA), myeloperoxidase (MPO), interleukin-(IL)-1β, and tumor necrosis factor alpha (TNF-α).

Ischemia and reperfusion of intestinal tissue (intestinal I/R) induce disruption of ileal contractility and chain responses of inflammatory. The aim of this study was to reveal whether therapeutic value of cannabinoid 2 (CB2) receptor activity in the intestinal I/R, via to the exogenous administration of CB2 agonist (AM-1241). Intestinal I/R injury were performed through 30-min ischemia and 150-min reperfusion of mesenteric artery in Wistar rats.
