Research ArticleOpen accessIn the abstractEffects of Purified Tick Saliva Toxins on Various Bio-Molecules in Blood Serum, Liver and Muscles of Albino MiceNidhi Yadav, Ravi Kant UpadhyayIn the present study, salivary toxins from Rhipicephalus microplus were isolated and purified on a Sepharose CL 6B 200 gel column at a constant flow rate with regular fractions of 5 mL/min. Pooled fractions were lyophilized and LD50 was then determined in albino mice. The LD50 value of the protein toxin of Rhipicephalus microplus was found 36.11 mg/kg body weight … …American Journal of Animal and Veterinary Sciences, Vol. 19, Issue 1 · 30 Dec 2023 · 5,358 accessesView PDFCite
Research ArticleOpen accessIn the abstractGeometry and Direct Kinematics to MP3R with 4×4 OperatorsRelly Victoria Petrescu, Raffaella Aversa, Bilal Akash et al.Anthropomorphic mechatronic systems are the most widely used robotics systems worldwide today in industry and in all automated environments. These systems are best suited to the modern automation and mechatronisation needs of the modern world, being mobile, dynamic, light, robust, complex, technologically simple, easy to design and manufactured, implemented, maintained and used in almost any industrial site, both in machine … …Journal of Mechatronics and Robotics, Vol. 1, Issue 2 · 1 Dec 2017 · 7,241 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation of Antioxidant and Antibacterial Activities of the Polysaccharides from Mycelium and the Culture Medium of Pleurotus Eryngii Strain UN-1Qing Liu, Haodong Wu, Ying Wu et al.Pleurotus eryngii was one of the most precious and ordinary edible mushrooms, and its polysaccharides were the major active substances. In this study, P. eryngii strain UN-1 was cultured in a liquid medium at 25℃ under a shaking of 80 rpm for 7 days. Two crude polysaccharides named CPN and CPNM were obtained from the mycelium of P. eryngii UN-1 … …American Journal of Biochemistry and Biotechnology, Vol. 18, Issue 3 · 19 Jul 2022 · 6,182 accessesView PDFCite
Research ArticleOpen accessIn the abstractA HPLC Method for Detection of 17 Characteristic Components in Tea ExtractYing Liu, Dan Wu, Ping Tang, Xingqian YeA HPLC method has been developed for the determination of tea for seven catechins ((+)-catechin, (−)-epicatechin, (−)-epigallocatechin, (−)-epigallocatechin gallate, (−)-epicatechin gallate, (−)-gallocatechins and (−)-gallocatechin gallate), two flavonols (quercetin, kaempferol), seven organic acids (Gallic acid, ferulic acid, protocatechuic acid, p-hydroxybenzoic acid，p-coumaric acid, erucic acid，vanillic acid) and caffeine. Using HPLC with gradient elution and photodiode array detection, seventeen compounds were separated and … …American Journal of Biochemistry and Biotechnology, Vol. 18, Issue 1 · 2 Feb 2022 · 7,034 accessesView PDFCite
Research ArticleOpen accessIn the abstractSimultaneous Detection of Nitrite and Nitrate in Celeries and CarrotsDongwu Liu, Jinye Niu, Ling Kong, Zhiwei ChenIn this study, the anions nitrite ion (NO2-) and nitrate ion (NO3-) in celeries and carrots were detected with the technique of ion chromatography. A Dionex ICS-2000 ion chromatograph was used to detect the content of NO2- and NO3- in celeries and carrots. NO2- and NO3- were separated on a DIONEX Ionpac AS19 A-4 mm ion-exchange column and an Iopac … …American Journal of Biochemistry and Biotechnology, Vol. 12, Issue 2 · 14 May 2016 · 7,216 accessesView PDFCite
Review ArticleOpen accessIn the abstractEffects of Intermittent Artificial Circulation in Summer Months on Chlorophyll a Concentration in a Small Eutrophic ImpoundmentAnusha Balangoda, Shafiqur Rahman, G. PadmanabhanImpact of artificial circulation on total algal biomass (as chlorophyll a integrated over depth) in a small eutrophic impoundment in the Northern Great Plains, was monitored over three consecutive summers. Chlorophyll a concentration and nutrient concentrations were measured at depths along water columns under aerated and non-aerated conditions at four sampling locations. Aeration destratified the water column, which resulted in … …American Journal of Environmental Sciences, Vol. 11, Issue 5 · 14 Nov 2015 · 7,311 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Non-Iterative Method for Factorization of Positive Matrix in Discrete Wavelet Transform Based Image CompressionNallathai Perumalsamy, Nithyanandam NatarajanA non-iterative method of factorizing a 4×4 positive matrix, with the application to image compression is explained using an example. The procedure is applied to all the 4096 number of 4×4 pixel sub-blocks of a 256×256 image for compression. The proposed compression technique can be applied to the Discrete Wavelet Transform (DWT) coefficients of the test image. The 16 Pixel … …American Journal of Applied Sciences, Vol. 10, Issue 7 · 17 Jun 2013 · 6,547 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparison of Radial and Axial Flow Chromatography for Monoclonal Antibody Downstream Processing at Bench and Pilot ScalesAli Demirci, Frank Leu, F. James BaileyAxial Flow Chromatography (AFC) is widely used for the purification of therapeutic Monoclonal Antibodies (MAbs). However, AFC columns can generate high pressure drops across the resin bed, preventing operation of the column at high flow rates especially at pilot or manufacturing-scales. Radial Flow Chromatography (RFC) was developed to provide lower pressure drops during chromatographic separations. In these studies, small and … …American Journal of Biochemistry and Biotechnology, Vol. 8, Issue 4 · 25 Dec 2012 · 11,516 accessesView PDFCite
Research ArticleOpen accessIn the abstractRemediation of Diesel Contaminated Soils Using Surfactants: Coulumn StudyE. Salehian, A. Khodadadi, B. HosseiniThis study presents the experimental remediation studies of diesel contaminated soil with Sodium Deducible Sulfate (SDS) as surfactants using column tests. Sandy selected soil had the grain size distribution of # 40 meshes to the # 200 mesh range. The soil columns were contaminated with adequate diesel amount to achieve the concentration of 10000 and 20000 ppm in soil. 0.1, … …American Journal of Environmental Sciences, Vol. 8, Issue 4 · 18 Jun 2012 · 8,325 accessesView PDFCite
