Research ArticleOpen accessIn the abstractGlutathione S-transferase (T1 & M1) Null Genotypes as Risk Determinants in Sudanese for Developing Type Two Diabetes MellitusGaafar Mahmoud, Hisham Mohamed Abdelrahim, Abed Al Salam Aljahmany, Eltayeb Mohamed Ahmed TayrabGlutathione S-transferases (GSTT1 and GSTM1) are globular proteins responsible for the detoxification of xenobiotics and the prevention of oxidative damage. Functional polymorphisms of the antioxidant glutathione and enzymes have a role in the pathogenicity of T2DM and its complications. The present study is aimed to assess association between GSTM1 and GSTT1 genetic polymorphisms with T2DM in Sudanese people. This case-control … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 3 · 16 Oct 2020 · 6,423 accessesView PDFCite
Research ArticleOpen accessIn the abstractA 10GHZ Low-Offset Dynamic Comparator for High-Speed and Lower-Power ADCSBakoune Pierre Hypolite, Wembe Tafo Evariste, Moukengue Imano AdolpheThis paper proposed a design of low-voltage Dynamic Comparator using 90 nm PTM CMOS technology for high-speed and Lower-power Analog to Digital Converter (ADC) applications. The double tail structure is employed as based for design new comparator with positive feedback due to best behavior in low-voltage that allows low delay time; decreases the offset voltage and power dissipation. Simulation results … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 2 · 6 May 2019 · 7,671 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnhanced Hybrid Spectrum Sensing Method Using TCDT and IEDT for Cognitive RadioNeha Chaudhary, Rashima Mahajan, Richa Adlakha et al.The development of efficient spectrum sensing techniques has witnessed progressive growth for optimum utilization of spectrum resources in cognitive radio. The primary objective of spectrum sensing is the identification and proper utilization of the spectrum holes. Nowadays, due to the advancement of wireless technologies, the demand for spectrum is also increasing and thus in turn, the requirement for better spectrum … …Journal of Computer Science, Vol. 20, Issue 11 · 20 Nov 2024 · 4,301 accessesView PDFCite
Research ArticleOpen accessIn the abstractGeneralized Statistical Inference for Quantiles of Two-Parameter Gamma DistributionMalwane AnandaGamma distribution is a widely used distribution to analyze data in many disciplines such as hydrology, meteorology, environmental monitoring, lifetime testing and reliability. In this study, we look at the statistical inference for the quantiles of two-parameter gamma distribution. The testing and estimation of gamma quantile are required especially in areas such as flood frequency analysis and life testing. For … …Journal of Mathematics and Statistics, Vol. 20, Issue 1 · 12 Feb 2024 · 5,910 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalysis of Interferon-Gamma Release Assay Results for Latent Tuberculosis Infection Diagnosis at a Referral Clinical Laboratory in South KoreaTae Soung Kim, Ga Yeon Kim, Young Ki Lee, Jae Kyung KimThe world health organization states that individuals with Latent Tuberculosis Infection (LTBI) are infected with Tuberculosis (TB) bacteria but do not show symptoms of active disease. However, they are at possibility of developing vigorous TB and potentially transmitting the illness to others. In 2018, South Korea reported a 14.8% positivity rate in LTBI screening, with higher rates observed among older … …American Journal of Biochemistry and Biotechnology, Vol. 19, Issue 4 · 25 Oct 2023 · 6,033 accessesView PDFCite

EditorialOpen accessIn the abstractThe Timeless Contribution of Rootstocks towards Successful Horticultural Farming: From Ancient Times to the Climate Change EraIoannis E. PapadakisGrafting is a horticultural practice by which living vegetative plant organs (root, stem and/or buds) of either the same genotype or, usually, different genotypes belonging to the same species, genus, subfamily and/or family, are tightly connected to each other to form a double-compound plant. In fact, it is a method of asexual (clonal-vegetative) propagation of plants. The basal part of … …American Journal of Agricultural and Biological Sciences, Vol. 11, Issue 4 · 16 Dec 2016 · 9,521 accessesView PDFCite
