2. Cardioprotective Effect of Cilostazol on Ischemia-Reperfusion Injury Model
Abstract Introduction: To clarify the potential protective role of cilostazol on rat myocardial cells with ischemia-reperfusion injury (IRI) models. Methods: The study was conducted with three groups of 10 Wistar rats (control group, rats without any coronary ischemia; sham group, rats with coronary ischemia but without cilostazol administration; and cilos

3. Persistent double strand break accumulation does not precede cell death in an Olaparib-sensitive BRCA-deficient colorectal cancer cell model
Abstract The poly (adenosine diphosphate (ADP)-ribosyl) polymerase inhibitors (PARPi) selectively kill cancer cells with BRCA1 or BRCA2 (BRCA)-mutations. It has been proposed that cell death induction after PARPi depends on unrepaired double strand breaks (DSBs) that accumulate due to the homologous recombination deficiency of BRCA-mutated cells. Such accumu

4. Effect of adenosine concentration on quality of cooled ram semen
ABSTRACT This study analyzed the adenosine concentration on quality of ram semen in different refrigerated storage times at 5 °C. The design was in blocks with repeated-measures factorial design. Five levels of adenosine and four refrigeration times were considered as fixed effects and the animal as random effect (block). Ram semen was diluted with Andromed

5. The perturbed expression of m6A in parthenogenetic mouse embryos
Abstract Parthenogenetically activated oocytes cannot develop to term in mammals owing to abnormal epigenetic modifications. Methylation of the N6 position of adenosine (m6A) is a post-transcriptional epigenetic modification of RNA. To investigate the role of m6A methylation in parthenogenetic (PA) embryonic development, we analyzed METTL3, METTL14, FTO, ALK

6. Evaluation of Myocardial Perfusion by Computed Tomography - Principles, Technical Background and Recommendations
Resumo A angiografia coronariana por tomografia computadorizada (ACTC) assumiu um papel de destaque na avaliação da doença arterial coronariana. Entretanto, sua natureza anatômica não permitia a avaliação da repercussão funcional das obstruções coronarianas. Recentemente, tornou-se possível a avaliação da perfusão miocárdica por tomografia com

7. On-Flow Ligand Screening Assay Based on Immobilized Nucleoside Diphosphate Kinase B from Homo sapiens
We describe an on-flow zonal affinity-based chromatography assay to screen ligands for the nucleoside diphosphate kinase B enzyme (NME2) from Homo sapiens. For the first time, we have covalently immobilized NME2 on the surface of an open fused silica capillary reactor (NME2-ICER) and placed the reactor before the analytical column, which resulted in a two-di

8. Direct Assay to Evaluate Phosphoenolpyruvate Carboxykinase Activity
Phosphoenolpyruvate carboxykinase (PEPCK) is a ubiquitous enzyme found in all known groups of organisms, acting in the reversible conversion of oxaloacetate (OAA) to phosphoenolpyruvate (PEP) in the presence of divalent metal ion, and dependent of adenosine 5’-triphosphate (ATP) or guanosine-5’-triphosphate (GTP). PEPCK is an important enzyme in the meta

9. Low triiodothyronine syndrome is associated with platelet function in patients with nephrotic syndrome
RESUMO OBJETIVO O objetivo deste estudo foi investigar os efeitos da síndrome do baixo triiodotironina (LT3S) na função plaquetária e nos fatores de coagulação em pacientes com síndrome nefrótica (SN). MÉTODOS Pacientes com síndrome nefrótica primária foram divididos em dois grupos, função tireoidiana normal (grupo A) e LT3S (grupo B), com

10. Feeding effects of cottonseed and its co-products on the meat proteome from ram lambs
ABSTRACT: Gossypol easily pairs with lysine side chains and enzymes involved in the cellular growth process. The effect of gossypol (a compound present in cotton co-products) in ruminant metabolism and meat quality is not yet clear. This study was undertaken in order to evaluate the effects of cotton co-products in lamb muscle proteome. Twenty-four Santa In�

11. Use of Idebenone for the Treatment of Leber’s Hereditary Optic Neuropathy
Abstract Leber’s hereditary optic neuropathy (LHON) is one of the most frequent mitochondrial disorders. It is caused by mutations in genes of the mitochondrial DNA coding for subunits of the respiratory chain and leads to severe bilateral vision loss, from which spontaneous recovery is infrequent. Retinal ganglion cells show a selective vulnerability to m

12. Assessment of Novel C-4 Methylated Tetraketide by HPLC-SPE-TT in Saccharicola sp., an Endophytic Fungus in Eugenia jambolana Lam.
A new compound named methyl (6S,7S,2E,4E)-6,7-dihydroxy-4,6-dimethyl octanoate was isolated from Saccharicola sp. using high performance liquid chromatography-solid phase extraction-transfer tube (HPLC-SPE-TT), together with four known compounds, fusaric acid, trans-4-hydroxymellein, thymidine and adenosine. Saccharicola sp. was isolated from the stems of Eu
