Abstract: Head and neck cancers (HNC) include a wide range of cancers that occur in different sites of the head and neck region. HNC constitutes 5-50% of all cancers globally and 5-8% of total body cancers in Europe and America. It is difficult to appreciate the burden of HNC in Nigeria because most studies available are hospital based. The aims of this study are to assess and compare the health related quality of life (HRQOL) in HNC patients before and at the end of radiotherapy treatment and to assess the effect of gender and stage of disease on HRQOL. This is a prospective study involving 100 patients with HNC at the Radiotherapy Department, University College Hospital, Ibadan, using two European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaires (QLQ), namely the General Cancer questionnaire (C30-QLQ) and Head and Neck Cancer specific questionnaire (H&N35-QLQ). The (HRQOL) was assessed pre-treatment and post radiotherapy. Fifty eight (58) were males while the rest were females. Their mean age was 49.86 years. Majority of patients are of the low socioeconomic class and had advanced disease. There was deterioration of HRQOL during treatment, with the nasopharynx and oropharynx tumours having more problems compared with other tumour sites. Role functioning, social functioning, pain, use of pain killers and financial difficulty were the most experienced symptoms. There is a reduction in the quality of life of the patients in the course of treatment. Pain is the main problem of these HNC patients, it requires more attention by the caregiver and awareness programs are needed to encourage early presentation.

Abstract: The Palm Oil was partially refined by adsorptive bleaching using kaolinite clay. The clay used was acid and alkaline activated and the performance of the activated and unactivated in terms of colour reduction was examined using the lovibond Tintometer. The results show that the activation with 2M H2SO4, 2MNaOH and the unactivated clay gave colour reduction of 75.13%, 69.90% and 64.68%respectively. Therein acid activated clay used for the adsorptive bleaching procedure was then used for the transesterification process. The physico-chemical properties of the partially refined and unrefined palm oil were determined. Palm oil biodiesel was produced through transesterification of palm oil with methanol at 600C using NaOH and K2CO3 catalyst. The biodiesel yield from NaOH and K2CO3 were 93.8% and 85% respectively. The fuel properties of the biodiesel was characterized using ASTM standard methods. Fuel test conducted on the methyl esters showed 86.7% and 85.9% reduction of viscosity over crude palm oil. The results obtained from the characterization of the biodiesel; %free fatty acid, acid value, flash point, cloud point, cetane number and fuel potential were compared favourably with those from other vegetable biodiesel as well as various international standards for biodiesel fuel.

Abstract: Diabetic foot ulcers are common serious complications associated with diabetes mellitus, and are the leading cause of hospitalization .These complications usually have an effect on patients quality of life .The nurse has two responsibilities ,first assess feet ulcer , second care of the wound by using appropriate sterile dressing techniques with the application of different solutions such as Honey, Der magran (Zinc-saline) and Ozonated olive oil and educating the patients about the proper foot management systems. Therefore the aim of this study is to compare the effect of ozonated olive oil ointment versus conventional dressing techniques on the healing of diabetic foot ulcers grade I .The study was conducted at Alexandria Main University Hospital and followed up for 10 months .The sample comprised 50 adult patients who had grade I foot ulcers. The sample was divided equally into two groups, study and control groups. The study group was treated by ozonated olive oil ointment, and control group was treated by hospital routine solutions (saline 0.9%, betadine 10%) once /day. This study revealed that, although the two dressing techniques (ozonated olive oil ointment and betadine 10%wet dressing techniques) were effective on the healing process of grade I diabetic foot ulcers, yet ozonated olive oil solution had better healing effect than conventional solution. Based on the results of the study, it is recommended that ,ozonated olive oil ointment should be used on a daily basis time to treat grade I diabetic foot ulcers, In the vascular out –patient clinics it’s preferable to use both dressing techniques in the management of patients with diabetic foot ulcer and increase nurses’ awareness about ozonated olive oil ointment dressing technique.

Abstract: The leaves of Rumex acetosa (Sorrel) was analyzed for its proximate and mineral composition using standard methods of food analysis. The result of the proximate indicated higher carbohydrate content of 63.81 0.18% which give rise to higher energy value since carbohydrate is a source of energy respectively. The leaves also had high energy value of 228.40 0.27 Kcal/100g. The mineral composition in mg/100g dry weight are K(2132.85 3.52), Na(28.61 0.48), Ca(53.25 0.05), P(7.73 0.07), Mg(73.56 0.02), Cu(0.85 0.04), Fe(10.81 0.04), Mn(13.59 0.04) and Zn(2.66 0.01). Higher potassium content in the leaves of this plant make it a better diets for hypertensive patient since any diets rich in potassium can reduce the risks of hypertension and possibly strokes. This findings also confirmed that the leaves of Rumex acetosa are rich sources of potassium, magnesium, copper, iron, manganese, and zinc as well as high energy values essential in human and animal nutrition.

Abstract: The effect of variation of Carbon-Silica Dual Phase Fillers (CSDPF) on the mechanical properties of natural rubber compounding was investigated. The natural rubber for the compounding process was sourced locally. Five different batches were prepared by varying the amount of carbon black and silica fillers present in them. These samples were subjected to different rheological and mechanical tests from where the samples with optimum rheological and mechanical properties were determined. It was found out that sample with higher proportion of carbon black followed by sample with equal amount of the carbon black and silica has the best rheological and mechanical properties. These observations were due to higher polymer-filler interactions and lower filler-filler interactions taking place in the compounds.

Abstract: Twenty eight male Friesian calves with average live body weight 176.673.68 kg and aged 80.19 months were divided into four similar groups (seven in each) assigned randomly to four experimental rations containing different levels of concentrate feed mixture and corn silage during the first (winter season) and second (summer season) periods. minerals content (Ca, P, Mg, Na, K, Cu, Zn, Mn and Fe) were higher in concentrate feed mixture compared with corn silage and increased in experimental rations with increasing the level of concentrate feed mixture and decreasing the level of corn silage. The contents of Ca, P, Na, Zn and Mn in corn silage were below the recommended requirements of growing calves. Minerals balance and concentrations in hair, blood plasma and body tissues increased significantly (P<0.05) with increasing the level of concentrate feed mixture and decreasing the level of corn silage in the rations. Calves fed all corn silage ration (R4) during the first period showed the negative absorption and retention of Ca, P, Na, Zn and Mn and were lower than the normal levels in hair and blood plasma.

Abstract: In this study a screening survey was undertaken to determine the presence and levels of aflatoxin M1 (AFM1) in locally produced dairy products. For this propose, a total of 141 dairy samples (raw milk, pasteursed milk, milk powder, yogurt and feta cheese)were analyzed to determined the level of AFM1 in these products.results obtained showed that AFM1 was found in 54.6% of milk and milk products samples. Lactic acid bacteria (Lactobacillus bulgaricus and streptococcus thermophilus) used for removal of AFM1in yogurt during manufacturing. It was found that Lactobacillus bulgaricus was of more binding ability than streptococcus thermophilus in reduction of AFM1, the results were discussed in details.
