This study assessed the concentration, degrees of contamination, and attendant health risk of heavy metals (HMs), using two major indigenous vegetables (Amaranthus viridis and Talinum triangulare) grown on five major dumpsites in Lagos state.

Production and Sensory Evaluation of Mixed Spices from Selected Local Spices Retailed in Ede, Nigeria.

Spices are essential group of agricultural products used to enrich taste and enhance nutritional contents of foods and beverages. Spices for various types of food were produced naturally from local available plant materials which have been used since the Middle Ages for flavoring, food additives and preservation, supplement, and/or medicinal purposes. Six spices, namely, (yellow pepper), (black pepper), (ginger), (scent leaf), castor seed (ogiri), and (curry leaf), were selected in their natural forms for the production single spices and mixed spices.

The experiences of wives following acquired brain injury (ABI). A qualitative analysis exploring realisations of change following the ABI of a "loved one.".

The experiences of family members following Acquired Brain Injury (ABI) are well established, with spouses in particular facing multiple relational and personal changes. Qualitative studies have analysed accounts pertaining to a range of sequelae, however, "change" itself has yet to be addressed. This study explored the experiences of realisation of change for married women living with their husbands following ABI.

Role of Chloride in the Corrosion and Fracture Behavior of Micro-Alloyed Steel in E80 Simulated Fuel Grade Ethanol Environment.

In this study, micro-alloyed steel (MAS) material normally used in the production of auto parts has been immersed in an E80 simulated fuel grade ethanol (SFGE) environment and its degradation mechanism in the presence of sodium chloride (NaCl) was evaluated. Corrosion behavior was determined through mass loss tests and electrochemical measurements with respect to a reference test in the absence of NaCl. Fracture behavior was determined via J-integral tests with three-point bend specimens at an ambient temperature of 27 °C.

Developing Anticancer Copper(II) Pro-drugs Based on the Nature of Cancer Cells and the Human Serum Albumin Carrier IIA Subdomain.

To synergistically enhance the selectivity and efficiency of anticancer copper drugs, we proposed and built a model to develop anticancer copper pro-drugs based on the nature of human serum albumin (HSA) IIA subdomain and cancer cells. Three copper(II) compounds of a 2-hydroxy-1-naphthaldehyde benzoyl hydrazone Schiff-base ligand in the presence pyridine, imidazole, or indazole ligands were synthesized (C1-C3). The structures of three HSA complexes revealed that the Cu compounds bind to the hydrophobic cavity in the HSA IIA subdomain.

Seasonal variation of malaria parasite density in paediatric population of Northeastern Nigeria.

Malaria is a major cause of morbidity and mortality in children and adults in the Sudano Sahel of Northeastern Nigeria with the highest prevalence of malaria in pregnancy of 64.5 in Nigeria recorded in this region. This study was carried out in 2003 and 2004 to provide parasitological baseline data for the development of Malaria Early Warning System (MEWS) for the surveillance of type I epidemic caused by meteorological conditions and to provide data for timing malaria key vector control measures such as Indoor Residual Spraying (IRS) for maximum effect.

Toxicological evaluation of the effect of water contaminated with lead, phenol and benzene on liver, kidney and colon of Albino rats.

The effect of water contaminated with phenol, benzene and lead on rats cellular system was investigated. Selected enzyme activity of the kidney and colon of rats was carried out. Standard enzyme assays were also conducted for selected liver enzymes such as alkaline and acid phosphatases, alanine and aspartate transaminases, and gamma glutamyl transpeptidase.

Dental erosion in a road-side battery technician: case report and a review of the literature.

Background: Tooth wear has been generally described as being caused by erosion, abrasion and attrition. Erosion is currently believed to be the major factor involved in tooth wear, and its contribution in the development of tooth wear may be increasing. Among the numerous causes of erosion, extrinsic factors are the most common.

Plasmodium/intestinal helminth co-infections among pregnant Nigerian women.

Hospital based studies were conducted to investigate the occurrence of Plasmodium/intestinal helminth co-infections among pregnant Nigerian women, and their effects on birthweights, anaemia and spleen size. From 2,104 near-term pregnant women examined, 816 (38.8%) were found to be infected with malaria parasites.

More infective larvae were recovered from the herbage in June, July and August than in other months.

Strongyloides papillosus infestations of lambs in Plateau State of Nigeria.

The frequent appearance of patent infestations of Strongyloides papillosus in lambs under one week is observed, and it is suggested that either the short generation interval or pre-natal infection is the cause. Pathogenic effects associated with heavy infestations in young lambs consisted of anorexia, loss of weight, diarrhoea and a moderate anaemia. The lambs were usually very weak, unable to stand and laying prostrate.

Effects of Aureo-S-700R on sporulation, viability and infectivity of ovine coccidial oocysts.

Sporulation rates of normal oocysts and oocysts isolated from lambs infected with coccidia and fed Aureo-S-700R for 25 days were studied at different temperatures. The viability and infectivity of the latter were also investigated. Temperatures of 5 and 10 degrees C inhibited sporulation of oocysts, but when the same oocysts were subsequently incubated at 25 degrees C, they sporulated.
