Research ArticleOpen accessEvery word in the titleHeterologous Expression and Biochemical Characterization of Lipase from Burkholderia cepacia Lu10-1Yao Zhang, Lu Wang, Yuanda SongEven though lipase genes from a variety of microorganism have been cloned and over-expressed, the prospective lipase resources for commercial production and industry application are still limited. In the present study, a lipase from Burkholderia cepacia Lu10-1 is heterologously over-expressed in Escherichia coli strain BL21(DE3) and purified to homogeneity. The molecular weight of the recombinant lipase from B. cepacia Lu10-1 … …American Journal of Biochemistry and Biotechnology, Vol. 13, Issue 4 · 23 Dec 2017 · 8,766 accessesView PDFCite
InvestigationOpen accessEvery word in the titleMorphogenetic and Biochemical Study on University Common Bean CollectionBeibitgul Zhumabaeva, Erika Dzhangalina, Zaure Aytasheva et al.This research has been conducted to reveal the outcomes of rotation of crops in mountain and steppe districts near Almaty. The main morphogenetic characteristics have been investigated for the collection of representatives of common bean, Phaseolus vulgaris L. by using samples from various countries such as Kazakhstan, USA, China, Czech Republic, Poland, Turkey and Russia under different climate and soil … …OnLine Journal of Biological Sciences, Vol. 17, Issue 4 · 28 Nov 2017 · 7,051 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleIntracellular L-Asparaginase from Bacillus sp. PG02: Purification, Biochemical Characterization and Evaluation of Optimum pH and TemperatureFatemeh Izadpanah Qeshmi, Mahsa Rahimzadeh, Sedigheh Javadpour, Manijeh PoodatBacterial L-asparaginases are amidohydrolases that act on L-asparagine and produce L-aspartate and ammonia. These enzymes have been used in treatment of lymphoblastic leukemia. In the present study, a novel strain, Bacillus sp. PG02 was explored for the production of intra-cellular L-asparaginase enzyme. The nitrogen source for L-asparaginase production was L-asparagine. New intracellular L-asparaginase was purified using ion exchange chromatography and … …American Journal of Biochemistry and Biotechnology, Vol. 12, Issue 1 · 26 Nov 2015 · 7,484 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePhysiological and Biochemical Evaluation of Fe-Efficiency in Fe-Deficient Maize GenotypesEntesar M. Essa, Sahar M. Zaghloul, Z.A. Salama et al.Iron (Fe) deficiency is prevalent particularly in calcareous soils of arid and semiarid regions. The present study aimed to investigate the response of eight local maize genotypes to Fe deficiency. In addition, a Fe- efficient (WF9) and a Fe-inefficient (ys1) indicator genotypes were used in this study. All genotypes were grown in growth chamber for 21 days in two levels … …American Journal of Agricultural and Biological Sciences, Vol. 10, Issue 1 · 22 Apr 2015 · 7,283 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleBiochemical Efficacy of Nigella Sativa Oil and Metformin on Induced Diabetic Male RatsYassmina K. Mahmoud, Sherif Y. Saleh, Abd El Rehim A. El Ghannam, Ibrahim A. IbrahimThis study was carried out to investigate possible beneficial effects of Nigella sativa oil supplementation to diabetic rats. Fifty male Sprague-Dawley rats were randomly divided into five groups (n = 10/group) as follows: group I (normal control), group II (diabetic control), group III (diabetic rats treated with metformin), group IV (diabetic rats treated with metformin and Nigella sativa oil) and … …American Journal of Animal and Veterinary Sciences, Vol. 9, Issue 4 · 24 Dec 2014 · 7,902 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleBiochemical Alterations Induced by Amylin in Wistar RatsMohamed Mohamed Soliman, Zein Shaban IbrahimAmylin is a peptide hormone synthesized in β cells of pancreas together with insulin in response to glucose and nutrients. Amylin controls food intake and body weight but the exact mechanism is still unknown. This study aimed to examine the effects of amylin injection on hormones, metabolites and cytokines expression in rats. Wistar rats were injected amylin Intraperitoneally (IP) (10 … …American Journal of Pharmacology and Toxicology, Vol. 8, Issue 2 · 7 Jun 2013 · 6,771 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFluctuation of Brain Tissue Oxygen Partial Pressure: A Biochemical Landmark in the Arctic Ground Squirrel's Spontaneous ArousalYi Long Ma, Shu Fen Wu, Lawrence K. DuffyHibernation in the Arctic ground Squirrel (AGS) is a regulated, adaptive response to arctic environmental conditions. Problem statement: Regional brain Blood Flow (rCBF) has been observed to increase dramatically during arousal in hibernators. However, the real time dynamic change in PtO2 during arousal has not been studied, we hypothesized that PtO2 is Interdependent of Tbrain and a key component in … …American Journal of Biochemistry and Biotechnology, Vol. 7, Issue 4 · 1 Feb 2012 · 7,605 accessesView PDFCite
