Salivary glands in workers of Ruptitermes spp. (Blattaria, Isoptera, Termitidae, Apicotermitinae): a morphological and preoteomic approach
(2021-01-01)
Salivary glands are omnipresent in termites and occur in all developmental stages and castes. They function to produce, store, and secrete compounds, ranging from a feeding function to defensive mechanisms. Here, we provide ...
Antiproliferative effect of apocynin in cervical epithelial cells infected by HPV 16 involves change of ROS production and cell cycle
(Springer, 2017-11-01)
The cervical cancer is characterized as a public health problem. The human papillomavirus, especially the high-risk types 16 and 18, is present in 99.7% of cases of invasive cervical cancers. Due to high prevalence, the ...
Effects of Pymetrozine on biochemical parameters and the midgut ultrastructure of Anthonomus grandis Boheman (Coleoptera: Curculionidae)
(Brill Academic Publishers, 2015-01-01)
Pymetrozine represents a class of compounds for the control of sucking insects. However, chewing insects have also shown sensitivity to this compound. Therefore, although pymetrozine has been demonstrated to have a direct ...
Morphological changes in rat rectus abdominis muscle induced by diabetes and pregnancy
(Assoc Bras Divulg Cientifica, 2018-01-01)
The urethral muscle of diabetic pregnant rats is affected by long-term mild diabetes and short-term severe diabetes, which plays a crucial role in the pathogenesis of pelvic floor disorders. We hypothesized that muscles ...
Structural rearrangements in the mitochondrial genome of Drosophila melanogaster induced by elevated levels of the replicative DNA helicase
(Oxford Univ Press, 2018-04-06)
Pathological conditions impairing functions of mitochondria often lead to compensatory upregulation of the mitochondrial DNA (mtDNA) replisome machinery, and the replicative DNA helicase appears to be a key factor in ...
Effects of short-term severe and long-term mild STZ-induced diabetes in urethral tissue of female rats
(2017-03-01)
Aims: To estimate and compare the alterations in the urethral tissues of female rats with two diabetes models: short-term severe and long-term mild diabetes. Methods: To induce mild diabetes (blood glucose levels between ...
Trend Toward Individualization of the Endocrine and Exocrine Portions of the Giant Anteater Pancreas (Myrmecophaga Tridactyla, Xenarthra)
(Wiley-Blackwell, 2017-06-01)
Considering the physiological importance of the pancreas as an endocrine and exocrine organ, this study described the characteristics of the gross and microscopic morphology of this organ using 16 Myrmecophaga tridactyla ...
Exposure to decabromodiphenyl ether (BDE-209) produces mitochondrial dysfunction in rat liver and cell death
(Taylor & Francis Inc, 2017-01-01)
Polybrominated diphenyl ethers (PBDE) are ubiquitous environmental pollutants. Exposure to these chemicals has been associated with developmental neurotoxicity, endocrine dysfunctions, reproductive disorders, and hepatotoxicity. ...
Analyses of the three 1-Cys Peroxiredoxins from Aspergillus fumigatus reveal that cytosolic Prx1 is central to H2O2 metabolism and virulence
(Nature Publishing Group, 2018-08-17)
Standing among the front defense strategies against pathogens, host phagocytic cells release various oxidants. Therefore, pathogens have to cope with stressful conditions at the site of infection. Peroxiredoxins (Prx) are ...
A high-fat diet fed during different periods of life impairs steroidogenesis of rat Leydig cells
(2016-01-01)
This study evaluated the impact of a high-fat diet (HFD) during different stages of rat life, associated or not with maternal obesity, on the content of sex steroid hormones and morphophysiology of Leydig cells. The following ...
