Pharmacodynamic Study of Parallel Groups Comparing the Effect of Rivaroxaban 20 Mg (Laboratorios Leti, S.A.V.) vs Rivaroxaban 20 Mg (Bayer Laboratories) on Prothrombin Time

引用

International Journal of Clinical Medicine 2024年第3期15卷 123-133页

作者： Elsy rodriguez de Roa mar.a Gonzalez Yibirin David Rincón Matute Carolina Aguilera Centro Médico Uslar Distrito Capital Caracas Venezuela Investigación Clínica Grupo Leti Guarenas Venezuela

Background: The prevalence of both atrial fibrillation (FA) and diabetes mellitus (DM) is increasing and they often occur together and constitute a high risk of thrombosis. Rivaroxaban is a Factor Xa inhibitor with a rapid onset and disappearance of action after oral administration;it acts by inhibiting the active form of the coagulation factor. In order to reflect the effect of the action of Rivaroxaban, we used the prothrombin time (PT);however, it′s not the most accurate, but it is the one available in our community. Methods: This was a prospective, randomized, analyst-blinded, parallel group clinical study to verify the efficacy of Rivaroxaban Leti 20 mg (RL) (12 volunteers vs Rivaroxaban Bayer 20 mg (RB) (13 volunteers). The variables were determination of PT and Partial Thromboplastin Time (aPTT) at baseline and at 24, 48 and 72 hours after administering a daily dose of 20 mg for three days. The determination was carried out with the IDG method (Integrated Diagnostics Group Sanzay Corporation) with an International Sensitivity Index (ISI) of 1.17 PT and aPTT were taken before the first dose, and then, every day during the next 3 days, three hours after the ingestion of their daily dose at 7 am. Results: The 25 healthy volunteers were similar in age, BMI, and SBP/DBP level with a greater number of men in the Bayer group. The efficacy of rivaroxaban was similar in both groups with prolongation of PTT to the 2nd day of treatment with PT, and percentage changes from baseline (14.46 ± 0.97 for RB vs 14.17 ± 0.94 RL p: 0.45), PTT results and percentage changes from the base (RB: 34 ± 4.53 RL: 33.46 ± 2.82). The safety of rivaroxaban was good in both groups with no serious adverse events. The equivalence in the logarithmically transformed PT result (ln) on day two, Mean and CI (90%) 99.2 (94.4-104) and 100 (99.5-100.8);neither the means nor the 90% confidence intervals of the PT variable transformed logarithmically to ensure its normality, were far from the 80%-125%

Effective Interaction Force between an Electric Charge and a Magnetic Dipole and Locality (or Nonlocality) in Quantum Effects of the Aharonov–Bohm Type

引用

Chinese Physics Letters 2021年第3期38卷 39-43页

作者： Gianfranco Spavieri George T.Gillies Miguel rodriguez maribel perez Centro de Física Fundamental Facultad de CienciasUniversidad de Los AndesMérida 5101Venezuela Department of Mechanical and Aerospace Engineering University of VirginiaCharlottesvilleVA 22904USA Departamento de Física Facultad de Ciencia y TecnologíaUniversidad de CaraboboNaguanagua 2001Venezuela Carrera de Ingeniería Ambiental Facultad de IngenieríaUniversidad Nacional de ChimborazoRiobamba 100150Ecuador

Classical electrodynamics foresees that the effective interaction force between a moving charge and a magnetic dipole is modified by the time-varying total momentum of the interaction fields. We derive the equations of motion of the particles from the total stress-energy tensor, assuming the validity of Maxwell’s equations and the total momentum conservation law. Applications to the effects of Aharonov–Bohm type show that the observed phase shift may be due to the relative lag between interfering particles caused by the effective local force.

Plant Proteins Are Smaller Because They Are Encoded by Fewer Exons than Animal Proteins

引用

Genomics, Proteomics & Bioinformatics 2016年第6期14卷 357-370页

作者： Obed Ramirez-Sachez Paulino perez-rodriguez Luis Delaye Axel Tiessen Genetic Engineering Department CINVESTAV Unidad IrapuatoIrapuatoCP 36821Mexico Colegio de Postgraduados Campus MontecilloTexcocoCP 56230Mexico

Protein size is an important biochemical feature since longer proteins can harbor more domains and therefore can display more biological functionalities than shorter proteins. We found remar.able differences in protein length, exon structure, and domain count among different phylo- genetic lineages. While eukaryotic proteins have an average size of 472 amino acid residues （aa）, average protein sizes in plant genomes are smaller than those of animals and fungi. Proteins unique to plants are -81 aa shorter than plant proteins conserved among other eukaryotic lineages. The smaller average size of plant proteins could neither be explained by endosymbiosis nor subcellular compartmentation nor exon size, but rather due to exon number. Metazoan proteins are encoded on average by -10 exons of small size [-176 nucleotides （nt）]. Streptophyta have on average only -5.7 exons of medium size （-230 nt）. Multicellular species code for large proteins by increasing the exon number, while most unicellular organisms employ rather larger exons （〉 400 nt）. Among subcellular compartments, membrane proteins are the largest （-520 aa）, whereas the smallest proteins correspond to the gene ontology group of ribosome （-240 aa）. Plant genes are encoded by half the number of exons and also contain fewer domains than animal proteins on average. Interestingly, endosymbiotic proteins that migrated to the plant nucleus became larger than their cyanobacterial orthologs. We thus conclude that plants have proteins larger than bacteria but smaller than animals or fungi. Compared to the average of eukaryotic species, plants have -34% more but -20% smaller proteins. This suggests that photosynthetic organisms are unique and deserve therefore special attention with regard to the evolutionary forces acting on their genomes and proteomes.
