PON1L55M AND Q192R  GENE POLYMORPHISMS IN CORONARY HEART DISEASE
Elevated Low density lipoprotein (LDL) / High density lipoprotein (HDL) ratio is a risk factor for predicting coronary artery disease (CAD). Paraoxonase 1 (PON1) is a HDL associated serum enzyme. PON1 protects LDL from oxidative modifications and thus has a protective effect against CAD progression. There are two common polymorphisms, Q192R and L55M, in PON1 gene. There may be a ... إقراء المزيد

Association between Helicobacter pylori Infection and Iron Deficiency Anemia among School-Age Children in Sohag University Hospital, Upper Egypt
Background: Helicobacter pylori (H. pylori ) infection has been suggested as a cause of iron deficiency anemia (IDA) refractory to iron therapy. Objective: The aim of this work was to evaluate the association between H. pylori infection and IDA among school-age children. Subjects and Methods: This was a prospective case-control study conducted for one year starting from March 2015 and ... إقراء المزيد

Tympanic membrane grafting, underlay periosteal versus inlay cartilage grafts: a comparative study
Abstract Various grafting materials and different ways of positioning have been described for tympanic membrane (TM) reconstruction. However, there are few clinical trials comparing cartilage and periosteal grafts. Aims: A comparison between underlay periosteal grafting (UPG) and inlay cartilage grafting (ICG) of TM. Material and Methods: A retrospective controlled trial. Group A, included 88 patients underwent UPG. Group B, included ... إقراء المزيد

Correlation between Unconfined Compression Strength (UCS) and Index Properties of Soil in Assiut Governorate, Egypt
Experimental tests are very important to determine the engineering properties of soils in geotechnical engineering. Special expertise and care are required to perform these tests. The unconfined compression test is also one of them. Thus, there is a need to develop models to quickly predict the unconfined compression strength of soils. The researchers attempted to develop correlations to predict the ... إقراء المزيد

SOME STUDIES ON THE EFFICACY OF A BIOFILM- DISSOLVING AGENT (SPRAY- CULT) TO IMPROVE RECOVERY OF BACTERIA FROM SURFACES OF MEAT PROCESSING EQUIPMENT.
Abstract Experiments with a biofilm dissolving agent (Spray- cult) were carried out to improve recovery of bacteria on surfaces of meat processing equipment. Spray- cult is a liquid reagent intended to improve recovery of bacteria from food- equipment surfaces. This reagent contains surface active compounds to disintigrate biofilms and make bacteria accessible for microbial testing by agar contact technique. This ... إقراء المزيد

BACTERIOLOGICAL EVALUATION OF BOTH PHYSIOLOGICAL AND PATHOLOGICAL (ICTERIC) YELLOW SHEEP CARCASSES
SUMMARY One hundred sheep carcasses were inspected at Qena abattoirs for determination of yellow colored carcasses. From the inspected carcasses 27(27%) were attained yellow coloration and could be differentiated into 18(66.6%) physiological and 9(33.3) pathological yellow colored carcasses. A total of 216 samples consisted of 144 from physiological and 72 from pathological yellow colored carcasses were collected from 8 different ... إقراء المزيد

Bactericidal and Antibiotics synergistic effect of Nanosilver against Methicillin-Resistant staphylococcus aureus.
ABSTRACT BACKGROUND: Methicillin-Resistant _Staphylococcus aureus _(MRSA) are bacteria responsible for several difficult-to-treat infections in humans. These strains have developed, through the process of natural selection. Infections by MRSA are more difficult to treat with standard types of antibiotics and thus more dangerous to human health. OBJECTIVES: The aim of this study was to evaluate the bactericidal and antibiotic synergistic effect ... إقراء المزيد
