Phosphoproteomic analysis of rat neutrophils shows the effect of intestinal isc...

Intestinal ischemia reperfusion injury (iIRI) is a severe clinical condition presenting high morbidity and mortality worldwide. Some of the systemic consequences of IRI can be prevented by applying ischemic preconditioning (IPC), a series of short ischemia/reperfusion events preceding the major ischemia. Although neutrophils are key players in the pathophysiology of ischemic injuries, neither the dysregulation ...

Mechanism of action and relationship between structure and biological activity ...

Made available in DSpace on 2022-04-29T02:57:32Z (GMT). No. of bitstreams: 0 Previous issue date: 2012-01-01; The increase in bacterial resistance to current antibiotics has led to the development of new active molecules. We have isolated the antimicrobial peptide Ctx-Ha from the skin secretion of the frog Hypsiboas albopunctatus. The aim of the present work was to elucidate the mechanism of action of this new ...

Paternal resistance training induced modifications in the left ventricle proteo...

Ancestral obesogenic exposure is able to trigger harmful effects in the offspring left ventricle (LV) which could lead to cardiovascular diseases. However, the impact of the father’s lifestyle on the offspring LV is largely unexplored. The aim of this study was to investigate the effects of 8 weeks of paternal resistance training (RT) on the offspring left ventricle (LV) proteome exposed to control or high-fat ...

Oxidonitrergic and antioxidant effects of a low molecular weight peptide fracti...

About 3000 tons of beans are not used in human food due to hardening. Several studies on bean-derived bioactive peptides have shown potential to treat some diseases, including those relying on oxidative dysfunctions. We assessed the effects of peptides extracted from hardened bean Phaseolus vulgaris (PV) on reactive oxygen species (ROS) and nitric oxide (NO) production, cytotoxic and cytoprotective effects in e...

Dynamic proteomic analysis of Aedes aegypti Aag-2 cells infected with Mayaro virus

Background Mayaro virus (MAYV) is responsible for a mosquito-borne tropical disease with clinical symptoms similar to dengue or chikungunya virus fevers. In addition to the recent territorial expansion of MAYV, this virus may be responsible for an increasing number of outbreaks. Currently, no vaccine is available. Aedes aegypti is promiscuous in its viral transmission and thus an interesting model to understand...

Paternal resistance training modulates calcaneal tendon proteome in the offspri...

The increase in high-energy dietary intakes is a well-known risk factor for many diseases, and can also negatively impact the tendon. Ancestral lifestyle can mitigate the metabolic harmful effects of offspring exposed to high-fat diet (HF). However, the influence of paternal exercise on molecular pathways associated to offspring tendon remodeling remains to be determined. We investigated the effects of 8 weeks ...

Molecular and cellular biomarkers of COVID-19 prognosis : protocol for the pros...

Background: Since the beginning of the COVID-19 pandemic, the world’s attention has been focused on better understanding the relation between the human host and the SARS-CoV-2 virus, as its action has led to hundreds of thousands of deaths. Objective: In this context, we decided to study certain consequences of the abundant cytokine release over the innate and adaptive immune systems, inflammation, and hemostas...

High performance mass spectrometry based proteomics reveals enzyme and signalin...

Comparison of two methods of tear sampling for protein quantification by Bradfo...

Compararam-se dois métodos de coleta de lágrima para quantificação proteica, utilizando-se 58 olhos de 29 cães hígidos. As amostras foram coletadas utilizando-se fitas de teste da lágrima de Schirmer (Schirmer tear test - STT) e tubos microcapilares. Após obtidas, as amostras foram congeladas a -80º C e posteriormente analisadas pelo método de Bradford. Os resultados foram analisados pelo teste T de Student. A ...

The crude skin secretion of the pepper frog Leptodactylus labyrinthicus is rich...

Peptidases are ubiquitous enzymes involved in diverse biological processes. Fragments from bioactive peptides have been found in skin secretions from frogs, and their presence suggests processing by peptidases. Thus, the aim of this work was to characterize the peptidase activity present in the skin secretion of Leptodactylus labyrinthicus. Zymography revealed the presence of three bands of gelatinase activity ...
