308 www.thelancet.com Vol 366 July 23, 2005 Introduction Epidemics of meningitis due to Neisseria meningitidis serogroup A are reported almost every year from subSaharan African countries, representing more than 600 000 affected individuals in the 1990s alone. The case fatality ratio (CFR) is estimated to be 10%, with a further 10–20% of patients developing neurological sequelae. During these e...

Cosmetics and topical products need not be sterile but may contain low levels of microbial load during use. This study was conducted to determine effectiveness of antimicrobial preservation during storage life of preparations and particularly the suitability of such preservative in terms of safety and broad spectrum activity. In this study, six formulations of both aqueous and oily cream were p...

Objective To evaluate the effects of testosterone (T) on the maintenance of corpus cavernosum (CC) structure and apoptosis. Methods Animals were divided into three groups: sham operation group (n = 8) underwent sham operation; Orchiectomized (Orchiec)+ oily vehicle group (n = 8) underwent bilateral orchiectomy and received a single dose of oily vehicle by intramuscular injection (i.m.) 30 day...

The production of olive oil in Morocco has recently grown considerably for its economic and nutritional importance favored by the country's climate. After the extraction of olive oil by pressing or centrifuging, the obtained liquid contains oil and vegetation water which is subsequently separated by decanting or centrifugation. Despite its treatment throughout the extraction process, this olive...

To recycle post-consumer HDPE contaminated with waste lubricating oils, companies include prior washing and drying in the process. This consumes large amounts of water and energy, generates significant effluent requiring treatment. This study assesses lubricating oil influence on HDPE properties to evaluate the feasibility of its direct mechanical recycling without washing. The current lubricat...

Objective. To examine the association between fish and marine long-chain omega-3 polyunsaturated fatty acid (LC n-3 PUFA) consumption and incidence of type 2 diabetes (T2D) in prospective cohort studies. Methods. Meta-analytic procedures were used to estimate the relative risk (RR) using random effects or fixed effects generic inverse variance model. Publication bias and study heterogeneity wer...

Many drug substances exhibit low solubility in water, which results in their poor bioavailability. Among ophthalmic preparations, oil solutions, suspensions and ointments are formulations prepared for such compounds. Promising modern drug carries are self-emulsifying drug delivery systems (SEDDS) which are isotropic mixtures of oils and surfactants. Due to presence of surfactants improved solub...

The aim of this study was to design and characterize a NdFeO3-based photocatalyst prepared by sol-gel method for treatment oily wastewater. Different characterization techniques such as X-ray diffraction (XRD), scanning electron microscope (SEM), Fourier transform infrared spectroscopy (FTIR), UV–vis spectrophometer were used elucidate the structure, morphology, surface functional groups, optic...
