In this study, the techno-economic approach of olive leaves ( L.) wastes for the removal of Cd from aqueous solutions was demonstrated. The adsorption process was illustrated regarding batch experiments and scanning electron microscopy, energy dispersive X-ray, and Fourier-transform infrared characterization.

Objective: Health-care waste has not attended much attention in developing countries. Staff is involved in cleaning and collect waste may often be at greater risk due to their less education and training. The current intervention study was conducted to improve knowledge and practice skills for medical waste handlers in some selected hospitals of Alexandria, Egypt.

Background: P53 protein plays important role in the maintenance of genome stability in mammalian cells; it acts in many processes including cell-cycle checkpoint, DNA repair, apoptosis, and angiogenesis. Mutations of P53 have been reported as common mutations in solid tumours, including non-Hodgkin lymphoma, NHL, and have been implicated in drug resistance, aggression and poor prognosis. Chronic infection with hepatitis C, HCV, has been associated in some studies with increased risk of NHL.

Circulating free DNA (CFDNA) has been shown to be a good source of liver tissue-derived DNA in African and Asian patients with chronic liver disease or HCC. In Egypt, HCC is a frequent carcinoma and mostly occur in the context of chronic infection by HCV, a widespread infection in the Egyptian population. Here we have examined the presence of mutations in TP53 at codon 249 (Ser-249, considered as a hallmark of mutagenesis by aflatoxin) and in CTNNB1 (gene encoding beta-catenin) in CFDNA of patients with HCC or chronic liver disease, from Alexandria, Egypt.

Over the past several years, the presence of fibrous asbestos particulates has been observed in a number of municipal water supplies throughout the USA, Canada, and several other regions all over the world. The possible health hazards which these fibers present have spurred a great deal of interest in the problems of detection and removal of the submicroscopic particulates in water. Asbestos is a group of fibrous metamorphic silicate minerals that is ubiquitous in the environment as a result of its extensive industrial use and the dissemination of fibers from natural sources.

Cancer among children is a substantial public concern. The epidemiology of childhood cancer is not fully understood. The descriptive epidemiology for cancer incidence has been a subject of considerable debate in order to identify and clarify the role of etiological factors and environmental exposure in cancer.

Though healthcare services aim to reduce the health problems and prevent the potential risks to the health of the community. These services create wastes which are considered as hazardous materials due to the higher potential of infection and injury possessed by these wastes than any other type of waste. Healthcare waste management is an integral part of healthcare services, and can create harm through inadequate waste management; thus reducing the overall benefits provided by healthcare centers.
