There are lots of nanoparticles that have less toxic effects on the different cells of fish immune system. Nanoparticles have low cost as compared to the other materials in delivering of biological materials. Nanoparticles have gained much interest as a specific and sensitive tool for diagnosis of bacterial, fungal and viral diseases in aquaculture. There are different types of nanoparticles such as Cu based nanoparticles, sliver nanoparticles, metal oxides nanoparticles such as ZnO and TiO2 NPs, or composite of several metals. The applications of nanoparticles in aquaculture has promisingly seen in water quality improvement, aquatic animal nutrition, drug delivery, disease diagnosis and management but very few works and has been done in the greener approach as it is forming a new horizon in the aquaculture era. Silver nanoparticle are employed for the cleaning fresh water inhabiting fishes due to advanced cleaning system and special plates that cleans each drop of water in each direction of movement of water. By improving disease control, feeding formulation, and biofouling control, nanotechnology can improve aquaculture production and shrimp culture.

Study to Investigate the Hormone Analysis in Male Albino Rats under the Pharmacological Kinetics of Thimerosal
Thimerosal is a compound centered on ethyl mercury which has been remained a component of vaccines. Vaccines and other medicinal product that hold thimerosal are the potential basis of relevance of havoc mercury. In the current study, the effects of thimerosal were checked on the sex hormones in adult albino rats at low 15mg/kg and high 40 mg/kg dose per day by the use of gavage for a month. Testosterone was noticeably reduced (p < 0.05) in both low and high dose treated rats. Concentration of LH and FSH also decreased (p < 0.05) tremendously in both treated groups. However, a minor decrease was observed in the level of prolactin in low dose group while prolactin was found to be reduced significantly (p < 0.05) in high dose exposure. Daily sperm production and efficiency of sperm production was also checked in this study and both are lowered sharply (p < 0.05) in rats treated with thimerosal. These results demonstrated that thimerosal has strong effects on male sex hormones and their DSP and efficiency of DSP in adult albino rats.

Paradigm shift in terms of patterns of conducting financial transactions in Nigeria is growing exponentially. Online channels are increasingly witnessing boom and silently eroding offline-based financial transactions. Notwithstanding appreciable progress regarding e-banking, elderly bank customers continues to engage hugely in physical presence in bank branches in order to perform financial transactions. Research focusing on constraining factors of e-banking channel usage intention among elderly (60+) bank customers in developing setting where e-banking is still somewhat nascent are few. This study, therefore, aims to deepen understanding regarding those factors that inhibit elderly banking customers’ intention to use e-banking channels. The study used a sample of 384 respondents determined statistically. A combination of judgemental and snowballing sampling techniques were applied in respondents’ selection. Questionnaire was used to collect data from the participants who volunteered to take part in the survey. Partial Least Square structural equation modelling (PLS-SEM) technique was utilised in data analysis. The research found that performance expectation, social influence, technology complexity, perceived security, and technophobia have significant-positive relation with attitude; also, attitude correlates positively with intention to use e-banking channels among the surveyed respondents. However, perceived trust and facilitating conditions have insignificant relations with attitude and usage intention. The practical implications of the findings and directions for future study were putforward.

Background: An attractive face, no doubt is pleasing to behold, however the definition of an attractive face is subject to factors such as personality, culture, age, ethnic background as well as personal preferences. Beauty, ugliness and handsomeness are subjective attributes ascribed to the facial appearance of individual. Though the determination of each is personal subjective, it is obvious that the human face is the most beautiful and attractive of all the mammals. Hence, this study was aimed at determining whether there is sexual dimorphism in the facial height, nasal height, mandibular height, maxillary height and orofacial height of the Ikwerre people in Rivers State. Materials and Methods: The study was cross-sectional that included males and females of the Ikwerre ethnicity of Rivers state of Nigeria. A total of 1,038 subjects comprising males (585) and females (453) aged between 5 – 45years were used for this study. The parents and grandparents were all from Ikwerre ethnic group. Each subject sat on a comfortable sitting position and then their facial measurements were taken including; facial height, nasal height, mandibular height, maxillary height and orofacial height. Results and Discussions: Results & Discussion: F.H. for males in the age grade 25yrs and above was 106.81±11.58, while for the females 101.24±6.98; N.H. for the males: 37.991±6.126, while for the females 38.344±6.255, Man. H. males: 47.511±8.016, females: 41.975±7.018; Max. H males: 22.08±21.16, females: 20.107±3.667, and O.H. males: 69.59±22.76, while females had 62.083±8.013. The result of the study showed that across the age categories the males consistently had higher values of the facial parameters investigated. Conclusion: The result of the study showed that there was sexual dimorphism with the male values of all the facial dimensions measured were significantly higher than female values (P<0.05).

Mustard as the medicinal plant used for the treatment of various diseases. There are 3 types of mustard: brown, oriental and yellow. Generally, the mustard seeds are mainly used in condiment or food industries in either oil or seeds form. The mustard plant is a plant species belongs to family Brassicaceae and the genera Brassica. The seed of mustard is used as spice. Derivatives of mustard constituent’s allyl iso-thiocyanate form basis for deadly agents such as anti-neoplastic drugs (e.g. bendamustine) and mustard gases. It helps for karyotyping process that centered on meiotic and mitotic chromosome and used many methods of staining comprising CMA3/DAPI fluorescence staining, Giemsa staining, silver staining, C banding, and fluorescence in situ hybridization with repetitive DNA sequences. As a source of vitamin-K plays its important role in serving with the blood clotting. It is also important and essential for the health of bone and heart. All these mustard species can also be utilized in the production of eatable oils. Both oriental and brown mustards are utilized to make the products which are spicier than the condiments which obtained from yellow mustard.
