Evidence of Heavy Metals Distribution in Placenta in Association with Residual Levels in Some Dams’ Organs from Bodija abattoir, Oyo State, Nigeria

Heavy metals have been known to be causing serious detrimental effect on the health of livestock and human populace in general. However, little study had been carried out on the ability of heavy metal to cross placental barrier, which has already been bio-accumulated in the dam. Therefore, this study aimed at showing the evidence of placental barrier crossing by selected heavy metals. The study was carried out in Bodija abattoir, Ibadan, Oyo-state, Nigeria, located on latitude 70020N, longitude 3005E. A cross-sectional study design was adopted and lasted for 6 weeks. Samples were collected from kidney cortices, apical lobe of dam’s liver and a portion of fetal placenta. 12 sample each from liver, kidney and the placenta which were analyzed using Atomic Absorption Spectrophotometer (AAS). Results were subjected to descriptive statistics, t-test and correlation using SPSS17.0 package.From this study cadmium (Cd) and lead (Pb) residues were not found in the samples, while chromium (Cr) was found in all the samples (100% prevalence) and the total prevalence for the heavy metals in the study was 33.4%. The mean chromium (Cr) residual values in placenta, kidney and liver were 0.89±0.66mg/kg, 1.32±0.94mg/kg and 1.00±0.87 mg/kg respectively. The correlation between chromium (Cr) in the dam’s kidney and placenta was 0.3, while for the dam’s liver and placenta was 0.6.  In comparison with permissible limit, the residual level in kidney 1.32±0.94, liver 1.00±0.87 and placenta 0.89±0.66, were within the permissible limit. The study revealed that chromium (Cr) residue was a major challenge in the organs sampled. Liver of the dam had the highest level of bioaccumulation and stronger correlation in the distribution to the placenta. It is therefore recommended that attention should be paid on the disposal of chromium (Cr) residues on the grazing floor where the bulk of the residues were from.

Factors affecting entrepreneurship development among the food marketers in Ilorin Metropolis, Kwara State, Nigeria

The study assessed the factors affecting entrepreneurship development among Food Marketers in Ilorin Metropolis, Kwara State, Nigeria. One hundred and ten respondents were randomly selected in four markets in Ilorin. The data was analyzed using frequency count, percentage, mean and Pearson Product Moment Correlation. The result reveals that mean age of the respondents was 30.5 years and about 58.2% were female. Record keeping skills (mean score =2.42) was the highest ranked entrepreneurial information needs of the respondents while lack of start-up capital (mean score =2.40) was the most severe factor affecting entrepreneurial activities of food marketers. There is a weak positive significant relationship between the entrepreneurial information needs and factors affecting entrepreneurial development of the respondents (r=0.407, p=0.0001). The study recommends that there should be provision of training on entrepreneurial skills based on the identified areas of needs and there should be provision of credit facilities to the food marketers as these will enhance their productivity.

Entrepreneurial information needs of Agricultural Students of Tertiary Institutions in Ilorin Metropolis, Kwara State, Nigeria

The study assessed the entrepreneurial information needs of Agricultural students in tertiary institutions in Ilorin metropolis. One hundred and  twenty-three respondents were randomly selected among the final year students of Agriculture in University of Ilorin and Kwara State Polytechnic  Ilorin. The data was analyzed using Frequency count, Percentage, Mean and Pearson Product Moment Correlation (PPMC). The result reveals that majority (91.1%) of the respondents were willing to go into entrepreneurial activities after graduation from the tertiary institution. The highest  ranked entrepreneurial information need was decision making skills ( = 2.79). Lack of start-up capital was the most severe factor affecting  entrepreneurial activities ( = 2.79). The result reveals that there was a significant relationship between the income (r=-0.356, p=0.0001), factors affecting entrepreneurial activities (r=0.509, p=0.0001) and entrepreneurial information needs of the respondents. The study recommends that there should be creation of more awareness on entrepreneurial opportunities to Agricultural Students of tertiary institutions. Key words: Entrepreneurial activities, Information Needs, Agricultural Students, Tertiary Institutio

Small Ruminant Farmers' Perception of Climate Change in Moro Local Government Area, Kwara State, Nigeria

This study examined the small ruminant farmers’ perception of climate change in Moro Local Government Area (LGA) of Kwara State, Nigeria. About 120 small ruminant farmers were selected for the study. Analyticall tools such as descriptive (frequency count, percentage, mean score) and inferential [Pearson product moment correlation (PPMC)] statistics were used to analyse the data. The result revealed that about 57.5% of the respondents were male, average age of 38.3years, income of N56633.33, and household size of about 5 persons. The average number of goat and sheep was 10 and 5 respectively. About 52% of the respondents utilized extensive system of rearing and 60.8% had access to extension services. About 77.5% of the respondents indicated Ministry of Agriculture as their main source of information on small ruminant production. The result revealed that planting of trees/erecting cover to serve as shades to reduce heat stress (90.8%) was the most frequently used adaptation strategies to climate change. About 59.2% of the respondents have high level/status of use of adaptation strategies. The highest ranked perception statement was increase in temperature (4.48), while disease outbreak and high mortality (2.78) ranked highest as factor affecting small ruminant production. It is therefore recommended that there should be provision of information on the adaptation strategies as climate change is now a reality that is not going away and provision of veterinary services to reduce disease outbreak

Competing Risk Modelling using Cumulative Incidence Function: Application to Recurrent Bladder Cancer Data

In this study, the effects of some clinical variables on the survival times of patients with bladder cancer were examined. The effects of these variables on sub-distribution of the failure types were determined using the proportional sub-distribution hazards regression model described in Fine and Gray (1999). Published dataset on 294 bladder cancer patients with four clinical outcomes were analyzed using Cumulative Incidence Function approach. The four outcomes included 184 (64%) patients that experienced recurrence of bladder cancer after receiving chemotherapy treatments. Two patients died of bladder cancer while 27 patients died of other causes and the remaining 76 patients did not experienced any of these three outcomes, and as a result, were considered censored. Among the covariates considered, only the patients’ initial number of tumors and initial size of tumor were incorporated into our analysis due to high proportion of missing observations in others. Results from this work showed that, patients with tumour recurrence have highest risk of dying than those from other causes. Further results showed that, the number of tumor was positively associated with the recurrence of cancer of the bladder. However, the size of the tumor did not demonstrate a significant effect on the patients’ survival time. It can therefore, be concluded that patients with tumor recurrence have low probability of survival from bladder cancer than patients that experienced other events. Above all, number, but not size of tumor could adversely affect the survival time of bladder cancer patients, especially those with tumor recurrence after bladder cancer treatment
