Research ArticleOpen accessEvery word in the titlePossible Physical Determination of the Mass, Size, Doubling Time and Density of the Unicellular Organisms Based on the Fundamental Physical ConstantsAtanas Todorov AtanasovIn manuscript the hypothesis 'that the mass, size, doubling time and density of the unicellular organisms (Prokaryotes and Eukaryotes) are determined by the gravitational constant (G, N·m2/kg2), Planck constant (h, J·s) and growth rate vgr (m/s)' is investigated. By scaling analyses it is indicated that the growth rate of the unicellular organisms ranges in a narrow window of 1.0×10-11–1.0×10-10 m/s, … …Physics International, Vol. 7, Issue 2 · 20 Nov 2016 · 8,253 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAdipose-Derived Canine Mesenchymal Stem Cells in PLAY® MediaArjun Kulkarni, Bhavana N. V., Teena Mary Thomas et al.In veterinary medicine, stem cell-based therapies present promise for addressing orthopedic and degenerative conditions in canines. Mesenchymal Stem Cells (MSCs) possess unique regenerative, immunomodulatory, and differentiation capabilities. However, their efficacy relies on optimal in-vitro conditions. Prolonged expansion over passages leads to a gradual loss of stem cell traits, highlighting the importance of optimized culture conditions and media supplements. This study … …American Journal of Animal and Veterinary Sciences, Vol. 19, Issue 3 · 13 Jul 2024 · 5,598 accessesView PDFCite
Research ArticleOpen accessIn the keywordsActivity Index and Author Exponential Growth on Forensic MedicineC. Baskaran, P. Ramesh BabuThe study examines the activity index and exponential growth of authors analysed during 1989-2016. The result of the study found that publications growth between 11 (0.26%) in 1989 and 447 (10.76%) in 201. RGR shows a fluctuates trend between 0.02 and 1.02 in 2005, 2006 and 1991 respectively. Complete twenty three years the research could be observed that RGR less … …Journal of Social Sciences, Vol. 15, Issue 1 · 14 Nov 2018 · 7,745 accessesView PDFCite
Research ArticleOpen accessIn the abstractExpression of Exosome-Derived MicroRNAs miR-21 and miR-135 are Differentially Regulated Among Dental Pulp Stem CellsMatthew Hunsaker, Brandon Richards, Adelle Fuller et al.Dental Pulp Stem Cells (DPSCs) are a type of mesenchymal stem cell that has the potential to differentiate into various types of cells and tissue. Previous research has demonstrated that DPSCs can be easily accessed and isolated from both permanent and deciduous teeth, such as wisdom teeth or third molars, although there is less information available about the mechanisms and … …Current Research in Medicine, Vol. 11, Issue 1 · 10 Jan 2023 · 10,533 accessesView PDFCite

Research ArticleOpen accessIn the abstractBifurcation and Controlling Chaos in a Discrete-Time Biological SystemGuo FengThe dynamics of a discrete-time food chain model with strong pressure on preys is investigated. The types of equilibria of the system are analyzed using stability theory and bifurcation theory. The route to chaos via Neimark-Sacker bifurcation followed by period-doubling bifurcations of invariant curves is found for some parameter values through numerical simulation. Moreover, the chaos is controlled on the … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 3 · 7 Jul 2020 · 6,681 accessesView PDFCite
Research ArticleOpen accessIn the abstractAccelerating Digital Forensics through Parallel ComputingGhada Elkabbany, Mohamed Rasslan, Heba AslanDigital crimes in the era of big data and cloud computing imposes significant challenges in digital forensics. Cloud environment provides low cost, easy management and reasonable solutions. Moreover, it supports big data structures and solutions (i.e., security, privacy and digital forensics). In order to achieve a secure digital forensics analysis in cloud environment, researchers have proposed solutions with expensive communication … …Journal of Computer Science, Vol. 14, Issue 2 · 20 Feb 2018 · 8,035 accessesView PDFCite
Research ArticleOpen accessIn the abstractBacteria as Quantum ClocksAtanas Todorov AtanasovIn this study we have investigated the biological application of Wigner’s inequalities for smallest quantum clock. We have shown that the mass, size and doubling time of bacteria satisfied the Wigner’s inequalities for quantum clock. Data on 17 bacteria with mass 1×10-17 -1×10-15 kg, size 0.3-50µm and doubling time 1×103-1×105 seconds confirmed the hypothesis of Pešić that possibly the living … …Physics International, Vol. 8, Issue 1 · 6 Sep 2017 · 7,994 accessesView PDFCite
EditorialOpen accessIn the abstractProtecting crop species from biotic and abiotic constraints in the era of Global Change: are we ready for this challenge?Marco Landi, Giovanni BenelliReliable and affordable supply of food is of crucial importance to the progress and stability of human societies. During the last century, we have assisted to an extraordinary increase of crop yields, especially for the most widespread and consumed crop species, such as rice, wheat, corn and soybean. The Broadbalk experiment, one of the oldest continuous agronomic experiments in the … …American Journal of Agricultural and Biological Sciences, Vol. 11, Issue 2 · 4 Jun 2016 · 8,399 accessesView PDFCite
Research ArticleOpen accessIn the abstractPassage Effect on Aging of Human Umbilical Cord Derived Mesenchymal Stem CellDian Mediana, Isabella Kurnia Liem, Jeanne Adiwinata Pawitan, Noviyanti GoeiTo be used in regenerative medicine, cells should be checked for various conditions, including cell aging. This study aimed to learn senescent profile and its relation to cell viability, proliferation and cell size in various passages, which were done in α-MEM-10% PRP medium, until senescence-associated β-galactosidase (SA-β-Gal) positive cells were found. Stem cells were isolated from umbilical cord tissue by … …OnLine Journal of Biological Sciences, Vol. 15, Issue 3 · 31 Jul 2015 · 8,039 accessesView PDFCite
