Research ArticleOpen accessEvery word in the titleRendezvous with Tat: Transactivator of Transcription during Human Immunodeficiency Virus PathogenesisSneham Tiwari, Madhavan P.N. Nair, Shailendra K. SaxenaAcquired immune deficiency syndrome is a deadly disease caused by HIV, declared as a global catastrophe engulfing millions of lives per year. It took ~1.8 million lives in the year 2010 alone, as per reports of UNAIDS. HIV-1 is an enveloped retrovirus, having genome composed of two copies of ssRNA. It attacks the T-lymphocytes of the hosts, causes several multifaceted … …American Journal of Infectious Diseases, Vol. 8, Issue 2 · 31 Jul 2012 · 7,627 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Impact of Changes in Forage Vegetation for Saiga (Saiga Tatarica) On Natural Pastures in The Steppe Zone of the West Kazakhstan RegionAmanay Myrzabayev, Zhanbolat Ibraibekov, Zhangeldi Ussenov et al.This study investigates the impact of recent climate changes and reduced anthropogenic pressure on the vegetation cover in the steppe regions of Russia and Kazakhstan, particularly focusing on the effects on saiga (Saiga tatarica) populations. By the late 1990s, a significant shift towards the dominance of grasses and the reduction of herbaceous plants in semi-arid and arid regions was observed, … …OnLine Journal of Biological Sciences, Vol. 25, Issue 4 · 7 Feb 2026 · 1,772 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAssessing of the Competitiveness Level in the Industry using the Correlation Analysis on the Example of Agriculture of the Republic of Tatarstan, Russian FederationSvetlana Fanilevna Khasanova, Aigyl Ilshatovna FazullinaThis study presents the results of evaluation of the competitiveness of farmers and the agricultural sector in the region as a whole. Traditional approach of estimating monopolization level uses Herfindahl-Hirshman and Lerner indexes. But this methods not applicable in case of inhomogeneity of product in industry or when firms manufacture different type of products. The evaluation was performed by using … …American Journal of Agricultural and Biological Sciences, Vol. 10, Issue 1 · 26 Mar 2015 · 7,473 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAnalysis of Photosynthetic Pigment Content and Leaf Structure of Pteroceltis Tatarinowii Mutant with Yellow LeafYongchang Yu, Chen Lv, Min Liu, Tiantian ChenThe relationship betweenleaf variation characteristics and leaf structure characteristics of Pteroceltistatarinowii with yellow leaf was explored to provide a theoretical basisfor the breeding of other ornamental plants. In this study, the differences inpigment content, leaf structure, and chloroplast ultrastructure in leaves of Pteroceltistatarinowii mutant with yellow leaf 'Huiguang' and its original species'Lingyansi No. 1’ were studied. The results showed that … …American Journal of Biochemistry and Biotechnology, Vol. 18, Issue 3 · 20 Sep 2022 · 5,602 accessesView PDFCite
Research ArticleOpen accessIn the keywordsNutritional control of HIV-AIDS-A case for SeleniumParisa Kalantari, Hema Vunta, Umamaheswari D. Palempalli et al.Selenium (Se) is a micronutrient that is incorporated into proteins. Some of the selenoenzymes such as GPXs and thioredoxin reductases exhibit glutathione peroxidase-dependent activities towards organic and inorganic peroxides. Thus, selenoenzymes play a pivotal role in mitigating oxidative stress caused by accumulation of peroxides. In this respect, selenoproteins may interfere with the transcription-driven by oxidative stress-dependent signaling mechanisms to influence … …American Journal of Infectious Diseases, Vol. 3, Issue 4 · 31 Dec 2007 · 7,346 accessesView PDFCite
Research ArticleOpen accessIn the author namesMonitoring of the Saiga Population: Balancing Nature and AgricultureZhanbolat Ibraibekov, Saule Atshabarova, Ermek Gabdullin et al.The rapid recovery of the Saiga population (Saiga tatarica) in Kazakhstan represents a significant conservation success; however, it has simultaneously generated complex ecological and socio-economic challenges in steppe ecosystems. This study evaluates the relationships between Saiga population density and pasture ecosystem condition and identifies ecological thresholds relevant to balancing biodiversity conservation and sustainable agricultural land use. The research is based … …OnLine Journal of Biological Sciences, Vol. 26, Issue 4 · 27 Oct 2026 · 50 accessesView PDFCite
Research ArticleOpen accessIn the author namesNeuronal Functions of Protein Phosphatase 2AHung-Tat Leung, Ning WangReversible protein phosphorylation is a common and important form of protein posttranslational modification which determines the proteins’ activities, substrate specificity and inhibitions or degradations, depending on the specific amino acid residue, or combination of residues, being targeted. While protein phosphorylations by kinases have been well studied, the importance of protein dephosphorylation by phosphatases has emerged over the past two decades … …Neuroscience International, Vol. 4, Issue 2 · 1 Apr 2014 · 7,783 accessesView PDFCite
Research ArticleOpen accessIn the author namesDynamics of Coherent Structures in the Coupled Complex Ginzburg-Landau EquationsTat-Leung YeeProblem statement: In this study, we study the analytical construction of some exact solutions of a system of coupled physical differential equations, namely, the Complex Ginzburg-Landau Equations (CGLEs). CGLEs are intensively studied models of pattern formation in nonlinear dissipative media, with applications to biology, hydrodynamics, nonlinear optics, plasma physics, reaction-diffusion systems and many other fields. Approach: A system of two … …Journal of Mathematics and Statistics, Vol. 8, Issue 3 · 6 Nov 2012 · 6,994 accessesView PDFCite

Research ArticleOpen accessIn the author namesA New Perturbative Approach in Nonlinear Singularity AnalysisTat-Leung YeeProblem statement: The study is devoted to the “mirror” method which enables one to study the integrability of nonlinear differential equations. Approach: A perturbative extension of the mirror method is introduced. Results: The mirror system and its first perturbation are then utilized to gain insights into certain nonlinear equations possessing negative Fuchs indices, which were poorly understood in the literatures. … …Journal of Mathematics and Statistics, Vol. 7, Issue 3 · 29 Jul 2011 · 7,334 accessesView PDFCite
