Crohn's Disease Confined to the Esophagus, with No Involvement of the Small or Large Bowel.

Unlabelled: Crohn's disease (CD) is a transmural inflammatory process that can affect any segment of the gastrointestinal tract. CD has a predilection for the colon and the small bowel, specifically the terminal ileum. Esophageal involvement of CD is exceedingly rare and there is a paucity of data regarding the disease phenotypes, course, complications and treatment.

Development of New Resolvin D1 Analogues for Osteoarthritis Therapy: Acellular and Computational Approaches to Study Their Antioxidant Activities.

In osteoarthritis (OA), oxidative stress plays a crucial role in maintaining and sustaining cartilage degradation. Current OA management requires a combination of pharmaceutical and non-pharmacological strategies, including intraarticular injections of hyaluronic acid (HA). However, several lines of evidence reported that HA oxidation by reactive oxygen species (ROS) is linked with HA cleavage and fragmentation, resulting in reduced HA viscosity.

Umbilical Cord Mesenchymal Stromal/Stem Cells and Their Interplay with Th-17 Cell Response Pathway.

As a form of immunomodulatory therapeutics, mesenchymal stromal/stem cells (MSCs) from umbilical cord (UC) tissue were assessed for their dynamic interplay with the Th-17 immune response pathway. UC-MSCs were able to modulate lymphocyte response by promoting a Th-17-like profile. Such modulation depended on the cell ratio of the cocultures as well as the presence of an inflammatory setting underlying their plasticity.

Epigenetic regulation of 15-lipoxygenase-1 expression in human chondrocytes by promoter methylation.

Objective And Design: 15-Lipoxygenase-1 (15-LOX-1) catalyzes the biosynthesis of many anti-inflammatory and immunomodulatory lipid mediators and was reported to have protective properties in several inflammatory conditions, including osteoarthritis (OA). This study was designed to evaluate the expression of 15-LOX-1 in cartilage from normal donors and patients with OA, and to determine whether it is regulated by DNA methylation.

Methods: Cartilage samples were obtained at autopsy from normal knee joints and from OA-affected joints at the time of total knee joint replacement surgery.

The whole experience of public hospital physicians from several specialties with biopharmaceutical effectiveness, safety, adverse drug reactions and interchangeability: A qualitative study.

Background: Although there is increasing support for biosimilar medicines by the Iraqi Ministry of Health (MOH), there is scarce information about whether physicians accept these medicines and support movement toward replacing reference medicines with their biosimilar counterparts.

Objectives: The study objectives were to 1) explore in-depth the perceptions of Iraqi physicians working in public hospitals about the difference in effectiveness and safety between biosimilar medicines and their reference biological counterparts 2) evaluate physicians' barriers to prescribing biosimilar medicines, 3) assess the adherence of physicians to the new pharmacovigilance regulations on reporting biopharmaceutical adverse drug reactions (ADRs) and 4) identify any barriers facing physicians to reporting biopharmaceutical- ADRs.

Methods: This qualitative study included face-to-face and virtual semi-structured interviews involving physicians from different disciplines who had experience with biological or biosimilar medicines.

Mass spectrometry-based proteomics identify novel serum osteoarthritis biomarkers.

Background: Osteoarthritis (OA) is a slowly developing and debilitating disease, and there are no validated specific biomarkers for its early detection. To improve therapeutic approaches, identification of specific molecules/biomarkers enabling early determination of this disease is needed. This study aimed at identifying, with the use of proteomics/mass spectrometry, novel OA-specific serum biomarkers.

Experimental Performance Analysis of a Pilot-Scale Biomass-Assisted Recirculating Mixed-Flow Dryer for Drying Paddy.

A large amount of heat energy is required for paddy drying processes to evaporate water from paddy grains. Currently, fossil fuels are being used as an energy source to heat air during the drying process. However, fossil fuels cause air pollution, climate change, and disruption of ecological balance.

Therapeutic Mesenchymal Stem/Stromal Cells: Value, Challenges and Optimization.

Cellular therapy aims to replace damaged resident cells by restoring cellular and molecular environments suitable for tissue repair and regeneration. Among several candidates, mesenchymal stem/stromal cells (MSCs) represent a critical component of stromal niches known to be involved in tissue homeostasis. , MSCs appear as fibroblast-like plastic adherent cells regardless of the tissue source.

In Vitro Cellular and Molecular Interplay between Human Foreskin-Derived Mesenchymal Stromal/Stem Cells and the Th17 Cell Pathway.
