The Value of SIRT1/FOXO1 Signaling Pathway in Early Detection of Cardiovascular Risk in Children with β-Thalassemia Major.

Background: Atherosclerosis represents one of the major causes of morbidity in children with β-thalassemia major (β-TM). Aim: This study was designed to investigate SIRT1-FOXO1 signaling in β-TM children and their role in early detection of premature atherosclerosis. Methods: We equally subdivided 100 Egyptian children aged 6−14 years with β-TM according to carotid intima media thickness (CIMT) into 50 with CIMT < 0.

Potential of Amantadine to Ameliorate Glutamate-Induced Pyramidal Cells Toxicity in Juvenile Rat' Brain Cortex.

Glutamate (Gt) neurotoxicity contributes to a wide spectrum of neurological conditions. Loss of glutamate transporters leads to intracellular Gt accumulation. Amantadin (AMn) is a non-competitive N-methyl-D-aspartate (NMDA) antagonist that can partially inhibit Gt transporters and influence protein phosphatase 2A subunit B (PP-2A-B) activity.

Glucose transporter-1 (GLUT-1) expression in psoriasis: correlation with disease severity.

Background: Epidermal hyperproliferation with abnormal differentiation, inflammation, and angiogenesis are the key features of psoriasis. Glucose transporter-1 (GLUT-1) is a member of facilitative sugar transporters that are integral membrane glycoproteins moving sugar across cell membrane.

Objective: The objective of this study was to study the GLUT-1 expression in psoriasis.

Mechanistic insights into the effects of quercetin and/or GLP-1 analogue liraglutide on high-fat diet/streptozotocin-induced type 2 diabetes in rats.

Background: The development of complementary treatment strategies that focuses on achieving a balance between adaptive and apoptotic unfolded protein response (UPR), enhancing endoplasmic reticulum (ER) homeostasis, and thus preserving β cell mass and function is particularly warranted.

Aim: This study was designed to investigate the effectiveness of the combined treatment by Quercetin (QUE) and Liraglutide (LIRA) in modulating hyperglycemia, insulin-insensitivity, UPR/ER stress markers, apoptosis, oxidative stress and inflammation using a high-fat diet/streptozotocin -induced type 2 diabetic rat model.

Methods: Sixty male albino rats were allocated into five equal groups: normal control, diabetic control, LIRA treated diabetic; QUE treated diabetic and combined treatment diabetic groups.

Cytokeratin-18 in Diagnosis of HCC in Patients with Liver Cirrhosis.

Background: Hepatocellular carcinoma (HCC) is a common malignancy that occurs secondary to viral hepatitis B and C cirrhosis under the influence of environmental factors. In early stages, clinical diagnosis is often difficult and distinguishing HCC from cirrhosis and other hepatic masses by conventional tests is frequently not feasible. Physicians usually depend on measuring serum alpha-fetoprotein (AFP), but this marker has low sensitivity and specificity.

Modulatory effects of resveratrol on endoplasmic reticulum stress-associated apoptosis and oxido-inflammatory markers in a rat model of rotenone-induced Parkinson's disease.

The mechanisms leading to neuronal death in Parkinson's disease (PD) are not fully elucidated; however, mounting evidence implicates endoplasmic reticulum (ER) stress, oxidative damage, and inflammatory changes are the crucial factors in its pathogenesis. This study was undertaken to investigate the modulatory effects of resveratrol on ER stress-mediated apoptosis, inflammatory and oxidative stress markers in a rat model of rotenone-induced PD. mRNA expression levels of ER stress markers; C/EBP homologous protein (CHOP) and glucose-regulated protein 78 (GRP78), were estimated in the rat brain using quantitative real-time PCR.

Higher Grades and Repeated Recurrence of Hepatic Encephalopathy May Be Related to High Serum Manganese Levels.

Hepatic encephalopathy is a serious complication of liver failure. Until now, the precise pathophysiologic mechanisms are not fully determined. It has been demonstrated that manganese plays an important role in the pathogenesis of hepatic encephalopathy.

Activity and expression pattern of NF-κB /P65 in peripheral blood from hepatocellular carcinoma patients - link to hypoxia inducible factor -1α.

Background: Hepatocellular carcinoma is a complex and heterogeneous tumor with poor prognosis due to frequent intrahepatic spread and extrahepatic metastasis. The molecular mechanisms underlying HCC pathogenesis still remain obscure.

Objectives: We aimed to investigate the abundance and the DNA binding activity of nuclear factor kappa B/p65 subunit in peripheral blood mononuclear cells from patients with HCC and to assess its prognostic significance and association with hypoxia inducible factor one alpha (HIF-1α) in blood.

p53 antibodies, metallothioneins, and oxidative stress markers in chronic ulcerative colitis with dysplasia.

Aim: To investigate the role of p53 antibodies (p53Abs), metallothioneins (MTs) and oxidative stress markers in the early detection of dysplasia in chronic ulcerative colitis (UC).

Methods: The study included 30 UC patients, 15 without dysplasia (group II) and 15 with dysplasia (group III), in addition to 15 healthy volunteers (group I, control subjects). The enzyme-linked immunosorbent assay technique was used to measure serum p53Abs and MTs, while advanced oxidation protein products (AOPPs), and reduced glutathione (GSH) levels were measured by spectrophotometric method in all subjects.

Central role of IL-10 as key regulator of inflammation during intestinal trichinellosis in mice.

This study characterized some immuno-pathological aspects of intestinal trichinellosis where, the influence of this nematode infection on levels of IL-10 mRNA expression, nitric oxide (NO) and myeloperoxidase (MPO) in intestinal mucosa is going to be studied. Four groups of albino mice were infected orally by Trichinella spiralis (T. spiralis) larvae and sacrificed on days 3, 6, 14, & 30 post infections (d.
