Evaluation of the physical properties of leathers tanned with Plectranthus barbatus Andrews extracts

This study was designed to assess the potential use of Plectranthus barbatus Andrews, a plant growing locally in Kenya as a vegetable tanning agent. The aim was a deliberate attempt to adopt green chemistry and provide cheap locally available eco-friendly tanning materials. Anova statistical test (α<0.05) was used to compare the physical properties of leather tanned with three kinds of liquors made from the...

MiR-124 involvement of apoptosis, immunity and regulator of diseases

Most microRNAs (miRNAs) are noncoding, conserved RNA molecules in vertebrates, and their roles are similar and very important. MiRNAs usually have tissue-specific expression, and abnormal levels of miRNAs have been associated with diseases and have been used as disease biomarkers. MiRNAs are widely involved in biological processes by regulating target mRNAs. MiR-124 is one of the best studied miRNAs in organisms. By...

Association of probiotic potential of strains of Pichia kudriavzevii isolated from “ogi” with the number of open reading frame (ORF) in the nucleotide sequences

In this study, a total of 9 morphologically and biochemically different yeast species were isolated from Nigerian fermented food product, ‘ogi’. These yeast species were screened for probiotic properties such as antibacterial activities, acid and bile tolerance. Six species out of the yeast isolates that survived pH 2 were grown in 0.3% bile salts which were monitored by spectrophotometer for 5 h. Three...
