Early Prediction of a Pre-Symptomatic Neurodegeneration Disorder by Measuring Macrophage Inhibitory Factor Level in Diabetic Patients.

Background: The relationship between diabetes mellitus and neurodegenerative disorders has been of great interest. Macrophage migration inhibitory factor (MIF) is a pro-inflammatory cytokine in which a variety of signaling cascades are activated through it. MIF has been involved in the pathogenesis of several diseases and can predict early pre-symptomatic stages of neurodegeneration in diabetic patients.

Bedside testing of CYP2C19 vs. conventional clopidogrel treatment to guide antiplatelet therapy in ST-segment elevation myocardial infarction patients.

Background: ST-segment elevation myocardial infarction (STEMI) patients are treated with dual antiplatelet therapy comprising aspirin and a P2Y inhibitor. Clopidogrel is widely used in these patients in several areas worldwide, such as Middle East, but is associated to sub-optimal platelet inhibition in up to 1/3 of treated patients. We investigated a CYP2C19 genotype-guided strategy to select the optimal P2Y inhibitor.

Protein networks linking Warburg and reverse Warburg effects to cancer cell metabolism.

It was 80 years after the Otto Warburg discovery of aerobic glycolysis, a major hallmark in the understanding of cancer. The Warburg effect is the preference of cancer cell for glycolysis that produces lactate even when sufficient oxygen is provided. "reverse Warburg effect" refers to the interstitial tissue communications with adjacent epithelium, that in the process of carcinogenesis, is needed to be explored.

Vildagliptin, a DPP-4 inhibitor, attenuates carbon tetrachloride-induced liver fibrosis by targeting ERK1/2, p38α, and NF-κB signaling.

Mitogen-activated protein kinases (MAPKs) and nuclear factor (NF)-ĸB signaling have been recognized for their causal connection with liver fibrosis. Hence, it is encouraging to discover drugs that can modify the interactions between these signaling cascades. It has been suggested that glucagon-like peptide-1 receptors (GLP-1Rs) might have a role in the observed hepatoprotection of dipeptidyl peptidase-4 inhibitors other than vildagliptin (VLD).

Bedside testing of CYP2C19 gene for treatment of patients with PCI with antiplatelet therapy.

Background: To mitigate the risk of stent thrombosis, patients treated by percutaneous coronary intervention (PCI) are administered dual anti-platelet therapy comprising aspirin and a platelet P2Y receptor inhibitor. Clopidogrel is a prodrug requiring activation by the cytochrome P450 enzyme, CYP2C19. In Saudi Arabia, it has been reported that approximately 26% of the population carries CYP2C19*2 and/or *3 loss-of-function polymorphisms in addition to a high prevalence of CVD.

Kidney injury molecule-1: A potential marker of renal recovery after laparoscopic sleeve gastrectomy.

Background: Bariatric surgeries were reported to improve diabetes and hypertension; however, the effect on renal recovery has not been fully explored. The aim of this study was to evaluate the effect of laparoscopic sleeve gastrectomy (LSG) in morbidly obese patients on renal function, degree of albuminuria, and kidney injury molecule-1 (KIM-1) level.

Methods: This was a prospective observational study conducted at Mansoura University Hospitals from January to June 2017.

Omega-3 offers better hypothalamus protection by decreasing POMC expression and elevating ghrelin hormone: a prospective trial to overcome methotrexate-induced anorexia.

Purpose: Methotrexate (MTX) therapy is widely used in treatment of different types of diseases including inflammatory diseases, autoimmune disorders, and cancer. However, most of patients respond well to MTX, they suffer from multiple side effects including severe anorexia. Omega-3 fatty acid possesses many beneficial biological activities.

New insights into weight management by orlistat in comparison with cinnamon as a natural lipase inhibitor.

Background And Objectives: Orlistat which is taken by obese patients may present some therapeutic assistance through its inhibition of lipase activity. Otherwise, a natural lipase inhibitor as cinnamon is widely used traditional medicine to decrease cholesterol and body weight. The current study aimed to investigate the weight management of orlistat in comparison with cinnamon through different obesity related targets.

Olmesartan ameliorates chemically-induced ulcerative colitis in rats via modulating NFκB and Nrf-2/HO-1 signaling crosstalk.

Alteration in the expression pattern of Nrf-2 and NFκB has been reported in ulcerative colitis (UC) in which functional crosstalk between these two critical pathways has been suggested. The ameliorative potential of the AT1R blocker olmesartan (OLM) on oxidative stress and inflammatory cytokines has received considerable attention in recent years. Acetic acid (AA)-induced UC demonstrates close resemblance to human UC regarding histopathological features and cytokine profile and is associated with local intense immune response, oxidative stress and release of inflammatory cytokines.

Ubiquitin-Proteasome Pathway and Muscle Atrophy.

Many systemic diseases are featured by muscle atrophy. Cellular proteins are modified by covalent attachment to a small protein known as ubiquitin (Ub) through ubiquitination. This ubiquitination process serves as signal for protein turnover that leads to rapid muscle mass lack.

Muscle proteolytic system modulation through the effect of taurine on mice bearing muscular atrophy.

Skeletal muscle atrophy occurs in different catabolic conditions and mostly accompanied with upregulation of Muscle ring finger 1 (MuRF1) gene which is one of the master regulatory genes in muscle atrophy. Taurine amino acid is widely distributed in different tissues and has anti-inflammatory and antioxidant effects. This study aimed to investigate the potential influence of taurine on muscle atrophy induced by reduced mechanical loading.

A shape tailored gold-conductive polymer nanocomposite as a transparent electrode with extraordinary insensitivity to volatile organic compounds (VOCs).

In this study, the transparent conducting polymer of poly (3,4-ethylenendioxythiophene): poly(styrene sulphonate) (PEDOT:PSS) was nanohybridized via inclusion of gold nanofillers including nanospheres (NSs) and nanorods (NRs). Such nanocomposite thin films offer not only more optimum conductivity than the pristine polymer but also excellent resistivity against volatile organic compounds (VOCs).
