Lack of Syndecan-1 promotes the pathogenesis of experimental rheumatoid arthritis.

Syndecan-1 (Sdc-1), a transmembrane heparan sulfate protein, is implicated in several pathophysiological processes including rheumatoid arthritis (RA). The exact role of Syndican-1 in this autoimmune disease is still undetermined. This study explores the involvement level of Sdc-1 in the development of RA in a collagen II-induced arthritis mice model.

The Mechanism and Potential Therapeutic Effects of Cyclosporin, Cyclophilin, Probiotics and Syndecan-1 in an Animal Model of Inflammatory Bowel Disease.

Inflammatory bowel diseases (IBDs) have several treatment modalities including immunoregulators, like cyclosporine A, an immunosuppressant that interacts with cytoplasmic cyclophilin A, and probiotics. This study explored and compared the possible role of syndecan-1 in the IBD pathogenic process as well as the effectiveness of cyclophilin A, cyclosporine A, and their combination in the management of IBDs in the presence of probiotics. IBD was induced in a total of 112 mice equally divided between knock-out (KO) and Balb/c wild-type mice, using 2% dextran sulfate sodium (DSS) followed by intraperitoneal treatment with cyclosporine A, cyclophilin A, or a combination of both.

Probiotics, gut microbiome, and cardiovascular diseases: An update.

Cardiovascular diseases (CVD) are one of the most challenging diseases and many factors have been demonstrated to affect their pathogenesis. One of the major factors that affect CVDs, especially atherosclerosis, is the gut microbiota (GM). Genetics play a key role in linking CVDs with GM, in addition to some environmental factors which can be either beneficial or harmful.

Highlights on two decades with microbiota and inflammatory bowel disease from etiology to therapy.

Inflammatory Bowel diseases (IBDs) constitute a complex panel of disorders characterized with chronic inflammation affecting the alimentary canal along with extra intestinal manifestations. Its exact etiology is still unknown; however, it seems to be the result of uncharacterized environmental insults in the intestine and their immunological consequences along with dysbiosis, in genetically predisposed individuals. It was the main target of our team since 2002 to explore the etiology of IBD and the related role of bacteria.

Nerve growth factor and burn wound healing: Update of molecular interactions with skin cells.

Burn wound healing is a very intricate and complex process that conventionally includes three interrelated and overlapping stages of hemostasis/inflammation, proliferation and remodeling. This review aims to explore the molecular interactions of NGF with the most prominent cell types in the skin and their respective secretory products during wound healing, particularly burn wound healing. Different types of cells such as, nerve cells, endothelial cells, mast cells, macrophages, neutrophils, keratinocytes and fibroblasts all come into play through a plethora of cytokines and growth factors including nerve growth factor (NGF).

Enhanced setup for wired continuous long-term EEG monitoring in juvenile and adult rats: application for epilepsy and other disorders.

Background: The electroencephalogram (EEG) is a widely used laboratory technique in rodent models of epilepsy, traumatic brain injury (TBI), and other neurological diseases accompanied by seizures. Obtaining prolonged continuous EEG tracings over weeks to months is essential to adequately answer research questions related to the chronobiology of seizure emergence, and to the effect of potential novel treatment strategies. Current EEG recording methods include wired and the more recent but very costly wireless technologies.

The impact of zoledronic acid on regenerate and native bone after consolidation and removal of the external fixator: an animal model study.

We investigated the role of zoledronic acid on the regenerate and native bone after consolidation and removal of the external fixator in a rabbit model of distraction osteogenesis using 28 New Zealand white rabbits. The rabbits were randomly distributed into two groups. The first group received three doses of zoledronic acid (ZA) 0.
