The use of nanoparticles in medicine is an attractive proposition. In the present study, zinc oxide and silver nanoparticles were evaluated for their antidiabetic activity. Fifty male albino rats with weight 120 ± 20 and age 6 months were used. Animals were grouped as follows: control; did not receive any type of treatment, diabetic; received a single(More)
Exposure to high levels of aluminum (Al) leads to neurodegeneration, which may be mediated through over-generation of free radicals. So, in the present study, we investigated the ability of both quercetin and omega 3 to ameliorate adverse effects of Al on brain antioxidants by monitoring the main brain antioxidant enzymes on molecular and cellular levels.(More)
Curcumin is widely used as a traditional medicine. This work was aimed to investigate its possible protective effect against chemically induced hepatocellular carcinoma (HCC) in rats. Fifty male albino rats were divided into five groups (n=10, each). The control group received a single dose of normal saline, the diethylnitrosamine (DENA) group received a(More)
OBJECTIVE Esophageal varices are a consequence of portal hypertension in cirrhotic patients. Current guidelines recommend that all cirrhotic patients undergo screening endoscopy at diagnosis to identify patients with varices at high risk of bleeding who will benefit from primary prophylaxis. This practice increases costs, involves a degree of invasiveness(More)
BACKGROUND Silver nanoparticles (Ag-NPs) are widely used nowadays in a variety of commercial applications including medical, health care, textiles and household supplies. OBJECTIVES The current study was designed to determine the median lethal dose (LC50) of Ag-NPs on Oreochromis niloticus and Tilapia zillii. METHODS Acute and sub-acute toxicity study(More)
OBJECTIVES To investigate the mechanisms of the anti-hyperglycemic effect of Costus speciosus (C. speciosus) root ethanolic extracts (CSREt) by assessing its action on insulin synthesis and glucose catabolic enzyme gene expression and activities in streptozotocin (STZ) diabetic rats. METHODS This study was carried out at the Biochemical Laboratory,(More)
— In this paper we present an algorithm for optical phase evaluation based on the wavelet transform technique. The main advantage of this method is that it requires only one fringe pattern. This algorithm is based on the use of a ً second /2 phase shifted fringe pattern where it is calculated via the Hilbert transform. To test its validity, the algorithm(More)
