Factors Affecting Energy Expenditure And The Efficiency Of Fuel Utilization: Feeding And Exercise Models

AbstractThe first aim of this dissertation was to monitor both rat andhuman responses to short-term perturbations in energy balancebrought about through food energy restriction and refeeding,exercise training and the cessation of exercise training orsurgical lipectomy. The second aim of this dissertation wasto identify factors which might explain differences in foodenergy intake in weight-matched, weight-stable "large andsmall eaters". The final aim of this dissertation was toidentify...

Effectiveness Of Pomegranate Punica Granatum L. Fruit Extract On The Sexual Function In Rats

ABSTRACTThe worldwide prevalence of erectile dysfunction (ED) in 1995 was estimated to be 152 million males, and the figure is expected to rise to 322 million by the year 2025. The inability to achieve or sustain an erection and/or an inability to ejaculate is common among men over 40 years, where about 5% will experience ED and rates increase with age. Pomegranate (Punica granatum L.) has traditionally been believed to be of importance in male sexual disorder management. This investigation w...

Nithogen Metabolism In The Ostrich

ABSTRACTThe thriving of the ostrich in an otherwise veryharsh environment has been an intriguing question to manypeople. The objective of this study was to find out someof the physiological explanations to this question.Some aspects of nitrogen metabolism were studied inthe as trich : Major urinary nitrogen metabolites inostrich urine (uric acid nitrogen, urea nitrogen andammonia nitrogen) were partitioned. Plasma urea andurinary ammonia levels were also determined usingcommercial kits based ...

Effects Of Exercise Training On Walking Function And Selected Cardiovascular Parameters Of Adult Patients With Stroke

ABSTRACT Clinicians are becoming increasingly interested in the use of exercise training to enhance functional outcomes and improve physiological parameters after stroke. The main aim of this study was to evaluate the effects of exercise training on walking function and selected cardiovascular parameters of adult patients with stroke. Sixty-seven (67) stroke subjects comprising 36 men and 31 women participated in the study. They were randomly assigned to two exercise groups (A and B)...

Effects Of Androgens In The Onset And Magnitude Of Salt – Induced Hypertension In Male Sprague – Dawley Rats

ABSTRACT Blood pressure is consistently higher in males compared with females from puberty onwards and men show an increased risk for hypertension compared to women. The gender disparity in cardiovascular functions and diseases has been linked to the effect of sex hormones on vascular reactivity. Although previous studies have suggested that the effect of chronic exposure to testosterone is an increase in vascular tone, it therefore implies that lack of testosterone should elicit vasore...

Prevalence Of Metabolic Syndrome Components By Age And Gender Among Maseno University Students, Kenya

ABSTRACTMetabolic syndrome (MS) is rapidly increasing in prevalence worldwide and is a top risk factor for noncommunicablediseases which are among the world's biggest killer diseases. In Africa, the prevalence ofMS is estimated to be between 17% and 25%. Studies have compared the prevalence of MS but yieldedvaried rates among the youth and adults in various countries. These variations are suggestive of the factthat MS components could be population dependent. The prevalence of MS and associat...

The Role Of Epithelial Sodium Channel And Sympathetic Nervous Potentiation In The Development Of Salt Sensitive Hypertension Among Nigerians In Lagos

ABSTRACT The mechanisms by which salt causes hypertension are not conclusive. Increased sympathetic activity and systemic vascular dysfunction have both been implicated as well as mutations of the epithelial sodium channel (ENaC) that resulted in increased reabsorption of salt from the distal nephron. However, although an adrenergic overdrive has been observed in some hypertensive patients, it is not clear whether this adrenergic overdrive is the hallmark of hypertension. It has equally ...

The Effects Of Aqueous Leaf Extracts Of Hybanthus Enneaspermus And Parquetina Nigrescens On Female Reproduction And Pregnancy Outcome In Sprague-Dawley Rats

ABSTRACT There is dearth of scientific information on the effects of Hybanthus enneaspermus (HE) and Parquetina nigrescens (PN) on female reproduction, pregnancy and its outcome. Yet, these two medicinal plants remain the first line of medicinal plants commonly used by Traditional Birth Attendants in care of women before, during and after pregnancy in South-west Nigeria. The effect of aqueous leaf extract of Hybanthus enneaspermus (HEaq) and Parquetina nigrescens (PNaq) on female reprod...

Impact Of Hibiscus Sabdariffa Calyx Aqueous Extract Consumption By Pregnant And Lactating Spraguedawley Rats On Pregnancy Outcome And Postnatal Development

ABSTRACT Extracts of Hibiscus sabdariffa (HS) are widely believed in folk medicine to be effective in the treatment of a variety of ailments. Aqueous extract of HS has been reported to decrease fluid and food consumption and weight gain in non-pregnant rats through mechanisms not yet fully understood. Thus when aqueous extract of HS is administered to pregnant and lactating animals, it may lead to decreased food consumption and consequently, malnutrition in these animals. Maternal malnu...
