Zinc-Mediated Reductive Acylation And Silylation Of Various P-Quinone Derivatives, Katrinah I. Tirado

USF Tampa Graduate Theses and Dissertations

Quinones are compounds containing cyclohexadiene diones and can be found in a variety of biological systems. Quinones participate in redox cycling to initiate the formation of free radicals which contributed to their overall biological activity. When quinones are reduced by either biological or chemical reductants, they can become unstable and undergo autoxidation back to their quinoidal form. One way to avoid autoxidation is the use of protected hydroquinones. Many protected hydroquinones in literature have been shown to be efficient in drug delivery as probes or molecular containers or they can act like prodrugs to be released into active forms to …

Identifying Factors Contributing To Under-Five Mortality In Nigeria, Olateju Alao Bamigbala, Ayodeji Oluwatobi * Ojetunde

Tanzania Journal of Science

The under-5 mortality rate (U5MR) is the probability that a child born in a specified year will die before turning 5 years of age. U5MR is still high in Nigeria. Therefore, this study aimed to identify factors contributing to under-5 mortality in Nigeria. The data used in this study were from the 2018 NDHS, encompassing 2013–2018. The methods of analysis used for this study were frequency, percentage, and Zero Inflated Negative Binomial (ZINB) regression. Data were analyzed using R programming v.4.1.2 and p < 0.05 was considered to be statistically significant. The result showed 35.4% under-5 mortality out of the 33,924 infant mortality sample data that were collected. The findings revealed maternal age, regions (North East and North West), maternal education (no education), wealth index (poorest households), and size of child at birth (very small birth size) as significant factors associated with under-5 mortality in Nigeria. The results also showed that the odds of under-5 mortality increase as the age of the mother increases. Therefore, the Nigerian government should understand that poverty is not just an economic problem but also a significant factor in health; as a result, the battle against poverty needs to receive the necessary attention.  Keywords:    Under-5 mortality; World Health Organization; Zero inflated distribution; Risk factors; Nigeria.
