Research ArticleOpen accessPhrase in the titleHeart Rate Variability Analysis in Different Age and Pathological ConditionsM.E.S. Chelladurai, N. KumaravelProblem statement: Heart Rate Variability (HRV) has been used as a measure of mortality primarily with patients who had undergone cardiac surgery. The analysis of Heart Rate Variability (HRV) demands specific capabilities which are not provided either by parametric or nonparametric conventional estimation methods. The Empirical Mode Decomposition (EMD) adaptively estimates the Intrinsic Mode Functions (IMFs) of nonlinear nonstationary signals. … …Journal of Computer Science, Vol. 7, Issue 10 · 4 Aug 2011 · 6,818 accessesView PDFCite
Review ArticleOpen accessPhrase in the titleSIRT1 Controls Lipid Metabolism Under Physiological and Pathological Conditions: Implications in AtherosclerosisAnastasia Vladimirovna Poznyak, Ludmila Viktorovna Nedosugova, Victoria Alexandrovna Khotina et al.This comprehensive review examines the multifaceted role of Sirtuin 1 (SIRT1) in cellular metabolism and energy regulation, with a particular focus on its involvement in lipid metabolism and glucose regulation. Additionally, SIRT1's impact on several pathologies, including osteoarthritis, diabetes, and cardiovascular disease, is explored. Notably, this review sheds light on the unique contribution of SIRT1 in the development and progression … …OnLine Journal of Biological Sciences, Vol. 24, Issue 4 · 7 Jun 2024 · 4,739 accessesView PDFCite
Research ArticleOpen accessIn the abstractChronic Lung Disease Identification in Chest CT Scans Through Hybrid Deep Transfer Learning FrameworkGarima Jain, Amit Kumar Goel, Rahul KumarAccurate and timely diagnosis is essential for successful treatment of chronic pulmonary conditions, particularly lung tumours. To capture more complicated pathological characteristics, diagnostic algorithms based on current data sets are restricted to using older databases and single branch systems. This research introduces a new solution: A hybrid deep learning model applied to a recently released quantitative database of CT scans … …Journal of Computer Science, Vol. 22, Issue 8 · 9 Sep 2026 · 651 accessesView PDFCite
Review ArticleOpen accessIn the abstractVLDL in Atherosclerosis: Variety of Mechanistic ImplicationsAnastasia Vladimirovna Poznyak, Victor Yurievich Glanz, Vasily Nikolaevich Sukhorukov et al.Very-Low-Density Lipoprotein (VLDL) particles play a pivotal role as precursors for Intermediate-Density Lipoprotein (IDL) and eventually transform into Low-Density Lipoprotein (LDL). These particles have been categorized based on size and particle charge. Various types of VLDL impact diverse physiological processes in the human body. The accumulation of VLDL, along with other triglyceride-rich lipoproteins, significantly contributes to the development of atherosclerotic … …OnLine Journal of Biological Sciences, Vol. 24, Issue 4 · 29 Jul 2024 · 4,308 accessesView PDFCite
Review ArticleOpen accessIn the abstractOverview of Vascular Smooth Muscle Cells, Endothelial Cells, and Macrophages Apoptosis During Atherosclerosis DevelopmentAnastasia Vladimirovna Poznyak, Varvara Alexandrovna Orekhova, Vasily Nikolaevich Sukhorukov et al.Atherosclerosis is a complex disease that has garnered significant attention from researchers studying its various aspects. Its pathogenesis involves a wide array of cellular and molecular components, as well as crucial mechanisms and processes crucial for cellular and organismal functioning. Atherosclerosis is considered a chronic inflammatory disease characterized by disrupted lipid metabolism, oxidative stress, and immune response. Apoptosis, a fundamental … …OnLine Journal of Biological Sciences, Vol. 24, Issue 4 · 5 Jul 2024 · 4,675 accessesView PDFCite
Review ArticleOpen accessIn the abstractFemale Sex Hormones Contribute to Vulnerability to Athero-Sclerosis: Overview of Mechanisms and Specific Risk FactorsAnastasia Vladimirovna Poznyak, Victoria Alexandrovna Khotina, Alexandra Alexandrovna Melnichenko et al.Atherosclerosis poses a significant challenge to the general population, with its prevalence particularly prominent among older individuals. Age, however, is not the sole determinant of risk, as gender also plays a crucial role. Sex-related disparities exist not only in the incidence of atherosclerosis but also in its progression and development. The intricate interplay of hormones in the female reproductive system … …OnLine Journal of Biological Sciences, Vol. 24, Issue 2 · 11 Jan 2024 · 4,633 accessesView PDFCite
Review ArticleOpen accessIn the abstractCardiolipin in Pathology: Implications in AtherosclerosisAnastasia Vladimirovna Poznyak, Vasily Nikolaevich Sukhorukov, Anton Yuvenalievich Postnov et al.Mitochondria are cell organelles whose main role is to generate the energy needed for cell biochemical reactions via oxidative phosphorylation. Cardiolipin is a phospholipid that is present in the inner mitochondrial membrane and other energy-transducing membranes. Mitochondrial structure largely depends on cardiolipin, as it is involved in the biogenesis of mitochondrial cristae, folds in the inner mitochondrial membrane designed to … …OnLine Journal of Biological Sciences, Vol. 23, Issue 4 · 23 Sep 2023 · 4,792 accessesView PDFCite
Research ArticleOpen accessIn the abstractMorphology and Histochemistry of the Corpus Luteum (CL) of Ovaries of Pregnant and Infertile CowsEvgeny Skovorodin, Svetlana Bogolyuk, George Bazekin et al.The purpose of our study is to study the functional morphology of the Corpus Luteum (CL) of the ovaries of pregnant and infertile cows in normal and pathological conditions. For that purpose, the ovaries of cows were examined after slaughter, histological and histochemical examination of the CL was carried out. For the antemortem examination of the ovary, the biopsy method … …American Journal of Animal and Veterinary Sciences, Vol. 15, Issue 4 · 23 Oct 2020 · 6,610 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
Research ArticleOpen accessIn the abstractDevelopment of a Short-Term Canine Full-Thickness Skin Organ Culture Method under Serum-Free ConditionsFrancesca Abramo, Andrea Pirone, Carla Lenzi et al.Full-thickness canine skin organ culture models could provide an entirely new opportunity for studying wound healing, keratinization disorders and allergic skin diseases, all of which have high prevalence and severe impact on canine quality of life.
