Research ArticleOpen accessPhrase in the titleSulfur Recovery from Acid Gas Using the Claus Process and High Temperature Air Combustion (HiTAC) TechnologyMohamed Sassi, Ashwani K. GuptaSulfur-bearing compounds are very detrimental to the environment and to industrial process equipment. They are often obtained or formed as a by-product of separation and thermal processing of fuels containing sulfur, such as coal, crude oil and natural gas. The two sulfur compounds, which need special attention, are: hydrogen sulfide (H2S) and sulfur dioxide (SO2). H2S is a highly corrosive … …American Journal of Environmental Sciences, Vol. 4, Issue 5 · 31 Oct 2008 · 17,605 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleImportance of blood gas measurements in perinatal asphyxia and alternatives to restore the acid base balance status to improve the newborn performanceH. Orozco-Gregorio, D. Mota-Rojas, M. Alonso-Spilsbury et al.Prolonged or intermittent asphyxia in utero and during farrowing weakens piglets and renders them less capable of adaptation to extrauterine life. Piglets with lesser viability at birth have increased blood pCO2 and blood lactic acid concentrations and decreased blood pH. Moreover, the ability to thermoregulate during an acute cold stress is inversely related to umbilical blood lactate concentrations. Blood gas … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 3 · 30 Sep 2007 · 7,631 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEffects 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 · 5,354 accessesView PDFCite
Research ArticleOpen accessIn the keywordsRETRACTED: Analysis of Interfering Substances in the Measurement of Malondialdehyde Content in Plant LeavesYunSheng Wang, MaoDi Ding, XunGang Gu et al.The Thiobarbituric Acid (TBA) reactive substances assay is an easy and quick assay for the assessment in plants of lipid peroxidation, in which Malondialdehyde (MDA) is derivatized. To analyze the applicability of this method, the MDA concentrations in the leaves of different plants were measured by the TBA method. To further separate the interfering substances, fractional extraction and Gas Chromatography-Mass … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 3 · 21 Sep 2013 · 9,288 accessesView PDFCite
Research ArticleOpen accessIn the keywordsImplications of Method Chosen for Analysis of Fatty Acids in Meat: A ReviewLivia Facuri Araujo Macedo, Ellen Cristina Quirino Lacerda, Roberio Rodrigues Silva et al.The influence of the beef Fatty Acid (FA) profile on human health, has become a recurring concern. For an analysis of the lipid composition of food, it is necessary that the complex lipids be quantified in a suitable form for subsequent analysis of their composition by gas chromatography. The choice of appropriate methods of lipid extraction and esterification of fatty … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 3 · 9 Jul 2012 · 8,633 accessesView PDFCite
Research ArticleOpen accessIn the abstractThermodynamic Inference of the Antioxidant Process of Malic Acid and Its Structural AnalogsHan Wu, Wenhao Dong et al.Two structural analogs of Malic Acid (MA), 2-isopropylmalic Acid (2-IPMA), and 3-isopropylmalic Acid (3-IPMA) were recently identified and separated from wine. Although they have been shown to have antioxidant activity, the mechanism of their actions is still unclear. Antioxidant activities of 2-IPMA and MA were tested through DPPH, ABTS, and PTIO methods and the antioxidant-related thermodynamic properties were evaluated using … …American Journal of Biochemistry and Biotechnology, Vol. 20, Issue 4 · 30 Oct 2024 · 4,824 accessesView PDFCite
Review ArticleOpen accessIn the abstractEfficiency and Sustainability of Alternative Protein Sources for Livestock Production in Sub-Saharan Africa: A Systematic Review and Meta-AnalysisOlusegun Oyebade Ikusika, Bulo Luvuyo, Jaja Ishmeal FestusSub-Saharan Africa (SSA) faces growing challenges in sustainable livestock production due to high costs and limited availability of conventional protein sources such as soybean meal and fishmeal. This systematic review and meta-analysis evaluated the nutritional efficiency and sustainability of locally available alternative protein sources for livestock feed in SSA. Following PRISMA guidelines, systematic searches were conducted across five databases (PubMed, … …American Journal of Animal and Veterinary Sciences, Vol. 20, Issue 4 · 19 Feb 2026 · 1,844 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Fertilization Frequency and Amount on the Chemometric Characteristics, Physiology, and Yield of Tomato Under Substrate CultivationEnling Ji, Qianqian Di, Qingjie Du et al.This study examined the effects of fertilization frequency and quantity on growth, yield, and quality of tomatoes under substrate cultivation. A factorial experiment evaluated two fertilization frequencies (every 5 or 10 days) and three fertilization levels (15.69, 31.38, or 62.76 kg·ha⁻¹), along with an unfertilized control. Plants were assessed for growth and development, photosynthetic pigment content, gas exchange parameters, nutrient … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 4 · 16 Feb 2026 · 1,715 accessesView PDFCite
