background: one of the affecting factors in disturbance process of spermatogenesis is chemotherapeutic-induced oxidative stress resulted from cyclophosphamide (cp) treatment which leads to diminished sperm quality via interference in spermatogenesis process. objective: this study was conducted to investigate the effects of ethyl pyruvate (ep) in reducing the cp-induced side effects on reproduct...

Serum creatine kinase isoenzyme 2 concentrations (CK 2 mass) were measured in marathon runners during training and 1 and 2 days after a race and compared with values from 36 acute myocardial infarction (AMI) patients whose total CK and (or) CK 2 activities were similar to those of runners in the basal state. During training, runners had CK and CK 2 activities 53% and 43% above reference values,...

B A C K F I R E ? In late June, Hong Kong media reported China’s PLA-AF (People’s Liberation Army – Air Force) would seek to become a ‘strategic air force’ with the acquisition of the Russian Backfire cited as a core tenet of this fundamental policy change. To best appreciate the potential strategic impact of the Backfire upon the Asia Pacific region it is worth exploring the capabilities of th...

This note describes possible world semantics for a constructive modal logic CK. The system CK is weaker than other constructive modal logics K as it does not satisfy distribution of possibility over disjunctions, neither binary (3(A ∨ B) → 3A ∨ 3B) nor nullary (3⊥ → ⊥). Our intuition is that 3⊥ should not constructively imply ⊥, thus we dispense with both forms of distribution. We are intereste...

The isoforms of CK-MB have recently received attention as potential biochemical markers for the early diagnosis of an acute myocardial infarction. A sensitive (analytical sensitivity = 0.2 ng/ml) immunochemical mass assay for the direct measurement of the CK-MB2 isoform has been developed by us. This assay utilizes a specific monoclonal capture antibody directed against the B-subunit of CK-MB a...

The purpose of this study was to determine the effects of two resistance exercise (RE) protocols with different rest intervals between sets on oxidative stress and exercise-induced muscle damage. For this purpose, twenty untrained males voluntarily participated in the research and were randomly assigned to one of two resistance exercise groups: a) a shorter inter-set rest interval of 90 second ...

Background: C-reactive protein (CRP), creatine kinase-muscle (CK-MM) and aldolase A (AldoA) levels are predicted to be realistic biomarkers of osteoarthritic disorders (OADs). The objective of the study was to evaluate the levels of CRP, CK-MM, and AldoA and determine their correlations with risk factors such as inflammation, muscle degeneration, and skeletal muscle damage for OADs. Methods: B...

Partindo da análise das manifestações de insatisfação usuários do Spotify no Twitter com o resultado Retrospectiva 2019, pretende-se investigar como a atuação dos algoritmos nas plataformas streaming música pode agenciar prática sonora ouvintes, tendo gosto musical um principais marcadores fruição ambiente digital. O artigo promove resgate conceito performance e busca repensá-lo partir dinâmica...

In this work, the postulation that weak CP phase originates in a certain geometry, is further discussed. According to this postulation, the weak CP phase is determined by three mixing angles. So, if we can determine experimentally three elements of the Cabibbo-KobayashiMaskawa (CKM) matrix, we can then determine the whole CKM matrix and correspondingly, the unitarity triangle. We find that the ...
