Protocolo para ensaios físico-químicos de estabilidade de fitocosméticos
(2008-10-28)
The growing demand for stable, safe and effective cosmetics has required increasingly complex studies by the scientific community and the use of more efficient techniques to determine the stability of these products. The ...
Photosynthesis and Stress Tolerance in Communities of Antarctic Snow Algae
(2019)
In maritime Antarctic snow algae form ubiquitous and diverse communities, whose
dynamics and biogeochemical processes influence atmospheric, terrestrial, freshwater
and marine realms. However, these biomes have been little ...
Antioxidative mechanisms protect resistant strains of Staphylococcus aureus against ciprofloxacin oxidative damage
(Wiley, 2010-12)
The aim of this investigation was to determine whether the antioxidant defences protect resistant strains of Staphylococcus aureus against ciprofloxacin oxidative damage. Reactive oxygen species (ROS) were determined by ...
Functional evaluation of ToxA promoter in Trichoderma reesei Rut-C30
(Trade science inc., 2016-01)
In order to expand the collection of promoters studied in Trichoderma reesei Rut-C30, a functional study of the ToxA promoter was carried out by analysis of GFP expression in T. reesei Rut-C30. For this purpose, the binary ...
Angiotensin I-converting enzyme modulates neutral endopeptidase activity in the rat
(LIPPINCOTT WILLIAMS & WILKINS, 2001-09)
Angiotensin I is a substrate for both ACE and for neutral endopeptidase 24.11 (NEP). We hypothesized that high ACE expression is related to low NEP activity. Accordingly, circulating and tissue NEP and ACE activities were ...
Using fluorescent lipids contributes to the active learning of principles underlying lipid signaling
(John Wiley & Sons Inc, 2018-12-25)
The concepts of phospholipase activity is often taught in undergraduate biology and biochemistry classes and reinforced in laboratory exercises. However, very rarely does the design of these exercises allow students to ...
Doxorubicin as an antioxidant: Maintenance of myocardial levels of lycopene under doxorubicin treatment
(Elsevier B.V., 2007-09-01)
The mechanism of doxorubicin-induced cardiotoxicity remains controversial. Wistar rats (n=96) were randomly assigned to a control (C), lycopene (L), doxorubicin (D), or doxorubicin+lycopene (DL) group. The L and DL groups ...
Cytomegalovirus and Toxoplasma gondii seroprevalence in a Brazilian liver transplant waiting list
(2007-12-01)
Cytomegalovirus (CMV) disease is a major cause of morbidity and mortality in solid organ transplantation. Disseminated toxoplasmosis after liver transplantation is a rare but fatal event. Serologic screening of the donor ...
