Phenolic acids have been reported to play a role on the antioxidant activity and other important biological activities. However, as most polyphenolics in food products are either bound to cellular matrices or present as free polymeric forms, the way they are absorbed has not been totally clear until now. Hydrolytic enzymes may act to increase functionalities in polyphenolic-rich foods, enhancing the bioaccessibility of phenolic compounds and minerals from whole grains. The aim of this study was to evaluate the action of tannin acyl hydrolase (tannase) on the total phenols, phenolic acid profile, antioxidant capacity and in vitro bioaccessibility of phenolic acids found in whole rye flour (RF)...

The development of new therapeutic strategies to control or reverse hepatic fibrosis requires thorough knowledge about its molecular and cellular basis. It is known that the heptapeptide angiotensin-(1-7) [ang-(1-7)] can reduce hepatic fibrosis and steatosis in vivo; therefore, it is important to uncover the mechanisms regulating its activity and cellular model of investigation. Ang-(1-7) is a peptide of the renin-angiotensin system (RAS), and here we investigated its modulatory effect on the expression pattern of microRNAs (miRNAs) in hepatic stellate cells (HSCs) LX-2, which transdifferentiate into fibrogenic and proliferative cells...

The Endoplasmic Reticulum (ER) is a membranous organelle with diverse structural and functional domains. Peripheral ER includes interconnected tubules, and dense tubular arrays called "ER matrices" together with bona fide flat cisternae. Transitions between these states are regulated by membrane-associated proteins and cytosolic factors. Recently, the small GTPases Rab10 and Rab18 were reported to control ER shape by regulating ER dynamics and fusion. Here, we present evidence that another Rab protein, Rab7a, modulates the ER morphology by controlling the ER homeostasis and ER stress...

The reverse sural flap has often been used for cutaneous coverage of the distal region of the leg and ankle. When the flap is performed in 2 stages, the vascular pedicle is exteriorized and later resected. Our goal was to assess the reverse sural flap performed in 2 stages regarding its viability and low morbidity along the flap-donor area. Eleven patients with cutaneous coverage loss found in the area between the distal third of the leg and ankle underwent cutaneous coverage surgery with a reverse-flow sural flap with an exteriorized pedicle, without violation of the skin between the base of the flap pedicle to the margin of the wound...

The SELF PRUNING (SP) gene is a key regulator of growth habit in tomato (Solanum lycopersicum). It is an ortholog of TERMINAL FLOWER 1, a phosphatidyl-ethanolamine binding protein with anti-florigenic activity in Arabidopsis thaliana. A spontaneous loss-of-function mutation (sp) has been bred into several industrial tomato cultivars, as it produces a suite of pleiotropic effects that are favorable for mechanical harvesting, including determinate growth habit, short plant stature and simultaneous fruit ripening...

The lack of digestibility of certain gluten proteins is essential in the development of celiac disease (CD). Gluten proteins are remarkably resistant to luminal and brush-border proteolysis owing to their high proline and glutamine content. Consequently, large fragments remain intact after digestion exerting toxic effects. Intestinal brush-border membrane vesicles (BBMV) have been described as having strong proteolytic activity mainly through prolyl endopeptidase enzymes. The purpose of this work was to monitor the gastrointestinal digestion of specific CD epitopes by means of an in vitro gastrointestinal digestion model that included incubation with brush-border membrane enzymes...

Photobiomodulation (PBM) is a simple, efficient and cost-effective treatment for both acute and chronic pain. We previously showed that PBM applied to the mouse head inhibited nociception in the foot. Nevertheless, the optimum parameters, location for irradiation, duration of the effect, and the mechanisms of action remain unclear. In the present study, the pain threshold in the right hind-paw of mice was studied, after PBM (810 nm CW laser, spot size 1 cm2 or 6 cm2 , 1.2-36 J/cm2 ) applied to various anatomical locations...

It is known that pesticides such as abamectin (ABA) present cytotoxic effects on target organisms; however, the effects from ABA on non-target organisms such as amphibians are poorly understood. The aim of the current study is to investigate whether the exposure of Lithobates catesbeianus tadpoles to different abamectin concentrations [12.5, 25, and 50% of the median lethal concentration (LC50 )] leads to behavioral and morphological changes and/or generates possible cytotoxic effects. The aggregation test showed that tadpoles exposed to the highest ABA concentrations did not respond to the stimulus from non-familial and unrelated co-specific species...
