Phytochemical Screening, Proximate Analysis and Mineral Composition of Cassia occidentalis Seed Extract.
(Asian Journal of Pharmaceutical and Health Sciences, 2011) Aransiola, S.A.
Qualitative determination of chemical and nutritional composition of Cassia occidentalis, an underexploited crop seed in Nigeria, was carried out. Seeds of C. occidentalis were found to be rich in crude protein, carbohydrate, and mineral elements. Mineral analysis of C. occidentalis showed the seed as good source of antioxidant micronutrients such as iron, calcium, potassium, sodium and magnessium. The phytochemical screening of the seed showed the presence of carbohydrate, terpene, steroid, sugar and tannins. Alkaloids, saponnins and glycosides were absent. Although the oil has a very low peroxide value and high iodine value, it cannot be recommended for consumption because of the low yield as well as its repulsive odour. The seed, however, can serve as a cheap source of protein, energy, as well as antioxidant micronutrients supplements in both man and animal.

Biological Treatment of Textile Effluent Using Candida zeylanoides and Saccharomyces cerevisiae Isolated from Soil.
(Advances in Biology, 2014) Aransiola, S.A.
This study evaluates the efficacy of yeasts isolated from soil in the treatment of textile wastewater. Two yeast species were isolated from soil; they were identified as Candida zeylanoides and Saccharomyces cerevisiae. The yeasts were inoculated into fask containing effluent and incubated for 15 days. Saccharomyces cerevisiae showed the most significant treatment capacity with a 66% reduction in BOD; this was followed closely by Candida zeylanoides with 57.3% reduction in BOD and a consortium of the two species showed the least remediation potential of 36.9%. The use of Saccharomy cescerevisiae and Candida zeylanoides in treatment of textile waste water will help to limit the adverse environmental and health implications associated with disposal of untreated effluent into water bodies.

Influence of Photoperiodic Levels of Skin Melatonization in Heteroclarias Fingerlings in Relation to Water Physico-chemical properties in Minna,
(Nigeria. Malaya Journal of Biosciences, 2018) Aransiola, S.A
An 8-week experiment was carried out to investigate the effects of photoperiodic levels on skin color of laboratory reared Heteroclarias fingerlings. Artificial lightning was used to simulate a range of photoperiod namely, continuous light period (24L: 0D), total darkness (24D: 0L), 12 hours of darkness and 12 hours of light (12D: 12L) and normal day and night period (control, i.e. ambient photoperiod). Adequately replicated representative number of Heteroclarias fingerlings were exposed to the various photoperiods and monitored for eight weeks. Results of physical observation of the fishes, following recommended fish skin color grading revealed that fingerlings reared in 24D: 0L had the darkest skin color, while those exposed to 24L: 0D had the lightest skin color. In addition, the fingerlings exposed to normal day and night period (control) had a light skin color while those exposed to 12L: 12D had a dark skin color. The physico-chemical parameters such as water temperature, pH, ammonia, biological oxygen demand and dissolved oxygen concentration were within the recommended range for fish culture and also indicated no significant differences(p>0.05) in all the treatments throughout the experimental period irrespective of photoperiodic condition. It is hoped that the findings of this study will guide commercial fish farmers in raising Heteroclarias fish according to the preferences of market demand with respect to skin color.

Effects of exercise on PR intervals, QRS durations and QTC intervals in male and female students of University of Abuja.
(2012-03) Ogedengbe, John Onimisi; Adelaiye, Alexander Babatunde
A study was conducted to determine the effect of exercise on Electrocardiogram (ECG) variables in students of University of Abuja, and gender variation of these variables was compared. Forty medical students were considered (22 males and 18 females), ages 18-30 years. The volunteers were subjected to exercise stress test by using bicycle ergometer. They exercised till exhaustion or attainment of 85% Heart Rate Maximum (HRmax) (Modified McArdle Protocol). ECGwas recorded pre and post-exercise. QTcintervals pre and post-exercise were 386.55 +/- 4.4ms and 415.82 +/- 4.89ms (range: 346 - 468ms) in males and 399.39 +/- 4.81ms and 409.11 +/- 4.44ms (range: 367 - 446ms) in females respectively. QTC was significantly raised post-exercise in male subjects. PR interval pre and postexercise were 153 +/- 5.09ms and 154.75 +/- 3.35ms (range: 116 - 206ms) in males and 160.44 +/- 6.5ms and 153.33 +/- 4.53ms (range: 116 - 243ms) in females respectively. QRS duration pre and post-exercise were found to be 90.86 +/- 0.97ms and 94.09 +/- 2.09ms (range: 83 - 122ms) in males and 87.44 +/- 1.36ms and 88.89 +/- 2.06ms (range: 80 - 113ms) in females respectively.

Heart Rate Variability in Healthy Young Adult Nigerians.
(West African Journal of Medicine, 2024-06-28) Chori, B S; Adamu, D B; Onaadepo, O; Ogedengbe, J O; Odili, A N
Objective: Heart rate variability (HRV) is a reliable, non-invasive indicator of autonomic balance. Its application in research and clinical medicine is hindered by the lack of consensus on normal values. This study sought to bridge this gap by providing normative values for short-term HRV measures in apparently healthy young adults. Methods: A descriptive cross-sectional study was carried out to determine short-term HRV measures using a 5-minute ECG recording among 840 healthy young adult Nigerians. Results: A total of 840 subjects between the ages of 15 - 40 years participated in the study, the majority of whom were women (56%). Mean (±SD) RR (ms), SDNN (ms), RMSSD (ms), LF (ms2), HF (ms2), LF (nu), HF (nu), and LF/HF were 831 (±138), 48 (±35), 57 (±49), 949 (±2598), 1802(±5135), 41 (±19), 58.90 (±19), and 1.42 (±4.6) respectively. Male participants had significantly higher mean RR (890.8 v 782.0, p<0.001), SDNN (52.4 v 43.8, p<0.005), RMSSD (63.6 v 50.9, p<0.005), LF (1218.5 v 731.8, p<0.001) and HF (2260.5 v 1429.5, p=0.002) than the female participants. No significant differences were found across age groups. Conclusion: Short-term resting HRV shows gender differences and higher vagally-mediated components among healthy young adults of native African descent. Interpretation of HRV parameters should take into account the age, gender, context, spectral analysis method, and duration of recording, among other factors.
