Several cases of dieldrin poisoning were reported amongst sprayers following repeated exposure to this insecticide. The symptoms developed by some of the most severe cases of poisoning included epileptiform convulsions. The effect of dieldrin on muscular efficiency of rats was studied. A state of chronic toxicity was produced by maintaining two groups of rats on a diet containing 25 p.p.m. and 50 p.p.m. of dieldrin respectively. A third group receiving a diet containing no dieldrin acted as a control. ...

Background: Colorectal cancer (CRC) rates are affected by genetics, ethnicity, and environmental factors; it is considered one of the most aggressive human malignancies with high mortality and morbidity rates worldwide due, in part, to its asymptomatic nature during the early stages of disease. Objective: Owing to the impact of microRNA (miRNA) dysregulation on CRC development and progression, this study was conducted to explore the expression levels of mir-21, -23a, and -27a in the sera and tissues ...

Decompressive craniectomy (DC) is a surgical procedure performed to manage intracranial hypertension. Once performed, patients are obligated to undergo another surgical procedure known as cranioplasty to reconstruct the cranial defect. Cranioplasty still has one of the highest rates of infection. The factors contributing to the high rate of surgical site infection (SSI) after cranioplasty are not well established. This study aims to estimate the incidence of SSI and determine its possible risk factors ...

Placenta accreta spectrum (PAS) disorders have become a significant life-threatening issue due to its increased incidence, morbidity and mortality. Several studies have tried to identify the risk factors for PAS disorders. The ideal management for PAS disorders is a matter of debate. The study objectives were to evaluate the incidence and risk factors of PAS disorders and to compare different management strategies at a tertiary referral hospital, Minia, Egypt.This prospective study included 102 women ...

The screen-printed technique is widely used as an efficient tool for electrochemical analysis in environment, clinical and agri-food areas. Significantly, it has the ability to transfer electrochemical laboratory experiments into the field. In the present work, we report a highly sensitive, simple, low-cost protocol for determination of amlodipine (AML) using bare/unmodified and DNA-modified screen-printed electrodes (SPEs). The immobilization of DNA molecules onto SPE offers promising robust and ...

Nifedipine and atenolol dugs are conjugated in several anti-hypertensive pharmaceutical formulations. Herein, a reproducible and sensitive voltammetric procedure has been developed for the simultaneous analysis of nifedipine and atenolol for the first time using MgO − nanoplatelets modified screen-printed electrodes (MgO − SPEs) via differential pulse voltammetry (DPV). Two very well-resolved and reproducible signals/oxidation peaks with a voltammetric separation of 0.35 V were obtained in Britton–Robinson ( ...

Hepatitis C virus (HCV) treatment is aiming to cure and prevent the development, progression of fibrosis, and related complications. Interferon-based therapy was claimed to reduce or even reverse fibrosis. Although direct-acting agents have a better cure rate, we still lack the knowledge of their effect on fibrosis regression. We aim to assess fibrosis regression in direct-acting agents compared with interferon-based treatment regimens in the treatment of chronic HCV patients. The 204 chronic HCV ...

Abstract The application of the genetic algorithms to the optimization of planar array weights will be investigated with −30 dB attenuators weight precision. The aim is to adjust the weight coefficients of the array attenuators in −30 dB precision to achieve a minimum sidelobe level (SLL) with narrower beam width. The peak sidelobe level (PSL) of the synthesized beam pattern has been successfully lowered. The results are compared with synthesized pattern using precision like weights such as Gaussian, ...

One part of the original PUF promise was their improved resilience against physical attack methods, such as cloning, invasive techniques, and arguably also side channels. In recent years, however, a number of effective physical attacks on PUFs have been developed [17,18,20,8,2]. This paper continues this line of research, and introduces the first power and timing side channels (SCs) on PUFs, more specifically on Arbiter PUF variants. Concretely, we attack so-called XOR Arbiter PUFs and Lightweight ...
