The “Journal of Biological Research and Biotechnology (Bio-Research)” is a peer-reviewed, multidisciplinary, international, scientific Open Access Journal that provides publication of articles on biological sciences and biotechnology. The journal established in 2003, is published by the faculty of Biological Sciences, University of Nigeria, Nsukka, Nigeria. The Journal welcomes submission of manuscripts in the form of original and reviews articles, brief and case reports, special communications and editorials, that meet the general criteria of significance and scientific excellence. Papers will be published online approximately one-to-two weeks after acceptance.

Publication of articles in the Journal of Biological Research and Biotechnology (Bio-Research) involves several parties, each of which performs an essential role in achieving the aims and objectives of the journal. Thus, all players (author, the journal editor, the peer-reviewer, and the publisher) are expected to meet and uphold standard norms of ethical behaviour from submission to the publication stage, depending on the area of involvement.

HSV-1 CPE in Vero E6 cells treated with AO, in relation to concentrations compared to the positive and negative control groups. The pink and orange bars represent treatments with andiroba oil at concentrations of 10 ng/mL and 100 ng/mL, respectively, compared to the positive control (green) and negative control (blue). It is observed that in all comparisons with the positive control, the CPE means with andiroba oil treatment were lower than the control means, except when compared to the negative control, where the treatment means were higher. However, it is noted that the means decrease according to the HSV-1 stratification: HSV-1 10⁻³ (3.67), HSV-1 10⁻⁵ (3.33), and HSV-1 10⁻⁷ (2.67) in the 10 ng/mL group, and HSV-1 10⁻³ (2.67), HSV-1 10⁻⁵ (2.33), and HSV-1 10⁻⁷ (2.33) in the 100 ng/mL group.
