ABSTRACT
Abstract: A biobank may be a form of biorepository that stores biological samples (usually human samples) to be used for diagnostic/ research purpose. Biobank became a key resource, supporting many varieties of up to date research like genomics and personalized medicine since 1990. A Biobank acts as a basement with the elaborated detailed information which are associated with the individuals from whom biological materials are collected. Establishment of assorted Biobank, the provision of human tissues/blood samples for translational research has been increased, which successively help in validation and standardization of diagnostic, prognostic and therapeutic predictive biomarkers. Biobank can be used for several research purposes like, in Cell and biological science, Blood Center, Pathology, Genetics, Bioengineering, Cryobiology and Bioinformatics. Biobanking helps in molecular profiling of samples. This review has emphasized on description of biobank, to grasp differing types, collection, storage, retrieval, ethical issues, applications, functionality of Biobanking in India and its limitations.

ABSTRACT
Abstract: Alcohol use continues to be an important global public health problem and adolescence is a period of developing drinking habits. The use and abuse of alcohol by adolescents is on the increase in most African countries and is closely associated with risky behaviours, STDs and mental disorders in adult life. This study aims to identify predictors that may significantly be associated with alcohol use among secondary school students in Calabar South Local Government of Cross River State. A cross-sectional analytical survey was conducted to identify predictors of alcohol use among secondary school students in the study area. A multistage sampling technique was used to select 5 out of 33 secondary schools. A sample size of 370 was calculated using Cochran formula. Data was collected from 370 respondents using semi-structured self-administered questionnaire administered using a proportionate allocation technique among the respondents. Mean age of respondents was 14.89 ± 2.19 years, with 203 (54.9%) between the ages of 11 and 15 years. One hundred and sixty-eight (45.4%) of the students drank alcohol, with the majority of consumers being SSS2 students, 60 (16.2%). The predictors of alcohol used in this study were: respondent’s ages, 11-20 years (p = 0.008), respondent’s type of school, public school (p = 0.025) and respondent’s class, SSS2 (p = 0.035). Parents, schools and health authorities need to create more awareness on the hazards of alcohol drinking. Policy makers should enforce the laws regulating drinking age, with particular focus on adolescent drinking.

ABSTRACT
Abstract: Hypertension is still a global burden till date with highest prevalence shifting from the high- and middle-income countries to the low-income countries of the world. Also, adequate knowledge and right perception of hypertension is still very low in such countries which most countries in sub-Saharan Africa belong. The study aims to determine the knowledge and perception of hypertension with associated factors in Ugep, an urban community in South-southern part of Nigeria. A descriptive cross-sectional study was conducted among adults (18 years and above) residing in Ugep community of Cross River State in South-southern Nigeria. A total of 192 consenting adults were recruited consecutively into the study during a medical outreach organized by Medical and Dental Consultant Association of Nigeria in August, 2017. Majority of the study participants (81.3%) demonstrated poor knowledge of hypertension while only a few of them were still holding wrong perceptions about the causes of hypertension. Among the socio-demographic factors explored, only educational status showed a significant association (p = 0.02) with the knowledge of hypertension among the study participants having no formal education being the poorest (93.0%). The knowledge of hypertension is still low among the Ugep community of CRS with some level of wrong perception about hypertension still persistent. Continuous education of the adult population of Ugep community is advocated in order to improve knowledge and perception of hypertension.
