Delimitation of the Pore in Tweety Homolog 1 Channels: A Model-guided Approach

J. P. Reyes, J. R. Castillo-Hernández, M. I. Maldonado-Cervantes, E. Maldonado-Cervantes, A. Rangel López, A. A. Vértiz Hernández & M. García-Rangel · Journal of Advances in Biology & Biotechnology · 2016

Tweety homolog proteins have been indicated as ´putative anion channels´, but yet there is some lack of definitive data in this regard. Here, we focused on the human Tweety homolog 1 protein (hTTYH1), and elaborated a model based on residue-coevolution analysis and ab initio prin...

Comparative Characterization of Neurotransmitter Receptor Genes in Tsetse Fly Genomes

Millicent T. Mumbo, George F. O. Obiero, Johnson Kinyua & Steven R. G. Nyanjom · Journal of Advances in Biology & Biotechnology · 2016

Tsetse flies are the sole vectors of African trypanosomiasis throughout sub-Saharan Africa. African trypanosomiasis is transmitted by the tsetse fly to humans (sleeping sickness or Human African Trypanosomiasis) and livestock (nagana or Animal African Trypanosomiasis) throughout...

Production, Purification and Characterization of Polygalacturonase from Aspergillus niger in Solid State and Submerged Fermentation Using Banana Peels

Francis Sopuruchukwu Ire & Emmanuel Garba Vinking · Journal of Advances in Biology & Biotechnology · 2016

Aims: Pectinases are extracellular enzymes produced by microorganisms which break down pectic polysaccharides of plant tissues into simpler molecules like galacturonic acids. Polygalacturonase catalyzes hydrolysis of α-1,4-glycosidic linkages in polygalacturonic acid producing D-...

Breeding Values of 254 Maize (Zea mays L.) Doubled Haploid Lines under Drought Conditions at Flowering and Grain Filling

A. M. M. Al-Naggar, A. M. A. Abdalla, A. M. A. Gohar & E. H. M. Hafez · Journal of Advances in Biology & Biotechnology · 2016

Breeding value is the main parameter of initial screening through top cross analysis as it represents the general combining ability (GCA) effects of individual test line. Two hundred fifty four top crosses were produced as a result of crossing between 254 doubled haploid lines (D...

Optical and Structural Properties of Protein Capped ZnO Nanoparticles and Its Antimicrobial Activity

Amit Kumar Bhunia, Tapanendu Kamilya & Satyajit Saha · Journal of Advances in Biology & Biotechnology · 2016

Protein coated ZnO nanoparticles (NPs) are prepared by green synthesis method in egg albumin medium. HRTEM analysis and absorption at~360 nm along with ~ 280 nm indicate the formation of protein coated ZnO NPs. Fluorescence study reveals the tryptophan emission~ 340 nm as well as...

Lecithin Isolated from Melon Seed Oil: Antioxidant Activity

Donatus C. Onah, Obioma U. Njoku, Patrick E. Aba & Jonas A. Onah · Journal of Advances in Biology & Biotechnology · 2016

Context: A number of antioxidants have been proposed for certain products; however, little information is available about the efficacy of vegetable oil lecithin as antioxidant in food products. Aim: The study was designed to extract and study oil from melon seed, then isolate and...

Phytochemical Screening and Antimicrobial Activity of Xylopia aethiopica and Gongronema latifolium on Common Pathogens

R. U. B. Ebana, U. M. Ekanemesang, U. O. Edet & E. F. Omoruyi · Journal of Advances in Biology & Biotechnology · 2016

The aim of the study was to determine the proximate composition, phytochemical composition and the antimicrobial potentials of the extracts of Xylopia aethiopica and Gongronema latifolium on some commonly encountered pathogens. The proximate composition results reveal that both p...
