Modulation of inflammatory and hormonal parameters in response to testosterone therapy: Effects on the ventral prostate of adult rats
(Wiley-Blackwell, 2018-09-01)
Testosterone is often recommended in the treatment of several aging-related conditions. However, there are still questions about the consequences of this therapy in terms of hormonal and inflammatory parameters that are ...
Isolation and characterization of a novel metalloprotease inhibitor from Bothrops alternatus snake serum
(2017-05-01)
Resistance of snakes and some other animals to snake envenomation has been attributed to soluble factors present in their tissues. Here we report the isolation of a novel metalloprotease inhibitor from Bothrops alternatus ...
A Social Parasite Evolved Reproductive Isolation from Its Fungus-Growing Ant Host in Sympatry
(Cell Press, 2014-09-08)
Inquiline social parasitic ant species exploit colonies of other ant species mainly by producing sexual offspring that are raised by the host. Ant social parasites and their hosts are often close relatives (Emery's rule), ...
Systematic and historical biogeography of the Bryconidae (Ostariophysi: Characiformes) suggesting a new rearrangement of its genera and an old origin of Mesoamerican ichthyofauna
(Biomed Central Ltd., 2014-07-08)
Background: Recent molecular hypotheses suggest that some traditional suprageneric taxa of Characiformes require revision, as they may not constitute monophyletic groups. This is the case for the Bryconidae. Various studies ...
An improved interolog mapping-based computational prediction of protein protein interactions with increased network coverage
(Royal Soc Chemistry, 2014-11-01)
Automated and efficient methods that map ortholog interactions from several organisms and public databases (pDB) are needed to identify new interactions in an organism of interest (interolog mapping). When computational ...
Hypotensive and vasorelaxant effect of Diapocynin in normotensive rats
(2017-05-01)
Nicotinamide adenine dinucleotide phosphate oxidase (NAD(P)H-oxidase) is a multicomponent enzyme system that generates superoxide anion by one-electron reduction of molecular oxygen and represents the major source of ...
Metalloproteomics Approach to Analyze Mercury in Breast Milk and Hair Samples of Lactating Women in Communities of the Amazon Basin, Brazil
(2018-02-01)
Mercury is a potentially toxic element that is present in the environment of the Brazilian Amazon and is responsible for adverse health effects in humans. This study sought to assess possible protein biomarkers of mercury ...
DNA barcode regions for differentiating Cattleya walkeriana and C. loddigesiiRegiões de DNA barcode para diferenciar Cattleya walkeriana e C. loddigesii
(2017-01-01)
Growers appreciate Cattleya walkeriana and C. loddigesii due to striking shape and rarity. Thus, this study aimed to evaluate the feasibility of DNA barcode regions, namely ITS1, ITS2 and rpoC1, to discriminate between C. ...
A protective vaccine against the toxic activities following Brown spider accidents based on recombinant mutated phospholipases D as antigens
(2021-12-01)
Accidents involving Brown spiders are reported throughout the world. In the venom, the major toxins involved in the deleterious effects are phospholipases D (PLDs). In this work, recombinant mutated phospholipases D from ...
Chromosomal evolution of tribe Oryzomyini (Rodentia: Cricetidae: Sigmodontinae)
(2022-01-01)
Oryzomyini is the most diverse tribe of subfamily Sigmodontinae, comprising 30 genera and 147 extant species. Cytogenetic studies on Oryzomyini reflect this diversity, revealing an exceptional range of karyotype variability, ...
