Research ArticleOpen accessEvery word in the titleA New Polyoxypregnane Glycoside from the Roots of Dregea volubilis (L.f) Benth. ex Hook. f and its Chondroprotective EffectSaksri Sanyacharernkul, Akanit Itghiarbha, Prachya Kongtawelert et al.Problem statement: Dregea genus (Asclepiadaceae) is well known for the rich of steroid pregnane contents and these plants are famous for the potential to be applied as alternative biological activities. Dregea volubilis is the only species of Dregea genus in Thailand. The chemical and biological investigations of this plant are interesting to bioassay-guided fractionation, particularly chondroprotective effect. Approach: The research … …American Journal of Biochemistry and Biotechnology, Vol. 5, Issue 4 · 31 Dec 2009 · 7,455 accessesView PDFCite
Research ArticleOpen accessIn the keywordsBiotransformation Using Recombinant Cmp Sialic Acid Synthetase and α-2, 6-Sialyltran Sferase: Enzymatic Synthesis of SialosidesUlrike Hubl, Cynthia Sun, Shuguang Zhang et al.In this research, we successfully expressed recombinant CMP-sialic Acid Synthetase (CSS) from Neisseria meningitides and 2,6-Sialyltransferase (SAT) from Photobacterium damsela in E. coli BL21(DE3) fermented at a scale of up to 8 litres using individual plasmids pIRL-1 and pIRL-4b, respectively. After cell lysis with BugBuster, enzyme levels of 2U and 22U per litre were produced for CSS and SAT, respectively. … …American Journal of Biochemistry and Biotechnology, Vol. 8, Issue 4 · 25 Dec 2012 · 8,854 accessesView PDFCite
Research ArticleOpen accessIn the keywordsProtective Effect of Enicostemma littorale Blume Methanolic Extract on Gentamicin-Induced Nephrotoxicity in RatsNiraj Mukundray Bhatt, Kinjal Chauhan, Sharad Gupta et al.Problem statement: The Amino glycoside antibiotics cause drug induced nephrotoxicity at therapeutic doses and thus limits the use clinically. Oxidative stress is one of the main reasons for the development of nephrotoxicity. Approach: In light of this the aim of the present study was to investigate the role of mitochondrial as well as post-mitochondrial oxidative stress in the development of … …American Journal of Infectious Diseases, Vol. 7, Issue 4 · 30 Nov 2011 · 9,547 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAntibacterial and Antioxidant Activities of Banana (Musa, AAA cv. Cavendish) Fruits PeelMatook Saif Mokbel, Fumio HashinagaThe fresh green and yellow banana peel of, (Musa, cv. Cavendish) fruits were treated with 70% acetone, which were partitioned with chloroform (CHCl3) and ethyl acetate (EtOAc), sequentially. The antioxidant activities of the extracts were evaluated by using the thiocyanate method, β-carotene bleaching method and 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical elimination. While, antimicrobial activities of the extracts and isolated components were … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 3 · 30 Sep 2005 · 16,037 accessesView PDFCite
Research ArticleOpen accessIn the keywordsMechanisms of Anti-Cancer Effects of Vernonia amygdalina Leaf ExtractUtoh-Nedosa Uchechukwu AnastasiaProblem statement: Vernonia amygdalina (V. amygdalina) has been shown to have cancer cell inhibition and cytotoxic effects. Approach: This study discusses the multi-faceted and multi-linked mechanisms by which cancer tissue inhibition and destruction is achieved by V. amygdalina leaf extract and powder (subsequently called V. amygdalina Extract). Cancer cell inhibition by V. amygdalina is suggested to occur through inhibition of … …American Journal of Pharmacology and Toxicology, Vol. 6, Issue 3 · 26 Oct 2011 · 9,090 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparative Studies on Proximate Composition and Phytochemical Screening of Mango, Key lime, African star apple and African pear Seeds as Possible Coagulant Aids for Water TreatmentAnimetu Seghosime, Johannes Akpabla Mawuli Awudza, Richard Buamah, Sampson Oduro KwartengMany fruits including mango (Mangifera indica), key lime (Citrus aurantiifolia), African star apple (Chrysophyllum albidum) and African or bush pear (Dacryodes edulis) are nutritionally valuable as human food, however after consumption of the fruits, their seeds are discarded as wastes since they are of no commercial value and this results in disposal problems. Hence assessment of the constituents of such … …American Journal of Environmental Sciences, Vol. 13, Issue 4 · 12 Aug 2017 · 9,950 accessesView PDFCite
Research ArticleOpen accessIn the abstractHeterologous Expression and Characterization of Thermostable Levansucrase (BsSacB) from Bacillus subtilis BB03Viniti Vaidya, Gajjeraman Prabu, D. Theertha PrasadThermostable levansucrase encoding gene (sacB) with its promoter was isolated from Bacillus subtilis BB03. BsSacB is composed of 1419 bp, encoding 473 amino acid residues and with promoter regions TTGCAA (-35) and TAGAAT (-10). The amino acid sequence analysis of BsSacB showed conserved motifs of microbial fructosyltransferase belonging to Glycoside Hydrolase family 68 (GH68). Comparative analysis of the protein structure … …OnLine Journal of Biological Sciences, Vol. 15, Issue 1 · 25 Mar 2015 · 7,371 accessesView PDFCite
Research ArticleOpen accessIn the abstractIdentification and Characterization of Antibiotic-Producing Actinomycetes IsolatesMeera Kumari, Bat-Erdene Myagmarjav, Birendra Prasad, Madhusudan ChoudharyActinomycetes are a gram-positive, filamentous subgroup of bacteria most known for antibiotic production. In fact, most of the antibiotics available today have originated from actinomycetes, namely from the genus Streptomyces. Novel bacteria with antimicrobial activities have been discovered from bacterial screen studies for decades and there is still much more yet to be unearthed. One hundred seventy five strains of … …Current Research in Microbiology, Vol. 4, Issue 1 · 25 Jun 2013 · 15,437 accessesView PDFCite
Research ArticleOpen accessIn the abstractAromatic Compound Glucopyranoside from New Species Artocarpus thailandicusWanaree Boonkla, Siripit Pitchuanchom, Puttinan Meepowpan et al.Problem statement: Many Artocarpus plants belonging to the family Moraceae are found in Thailand and have been used as Thai traditional medicines. These plants are known to produce a variety of phenolic glycoside. A. thailandicus is the new species and this prompted us to make further investigations on the occurrence of these types of compounds in the new Artocarpus species. … …American Journal of Applied Sciences, Vol. 8, Issue 11 · 23 Sep 2011 · 8,016 accessesView PDFCite
Research ArticleOpen accessIn the abstractBioassay Guided Isolation of Antibacterial Compounds from Andrographis paniculataAbubakar Sule, Qamar Uddin Ahmed, Othman Abd. Samah et al.Problem statement: Chronic disease-causing bacteria of medical importance have developed resistance to antibiotics, hence, necessitating distinct and constant need for safe and efficient therapeutic agents.
