Proteomic and physiological approaches reveal new insights for uncover the role of rice thylakoidal APX in response to drought stress
(2018-01-01)
Chloroplast APX isoforms display controversial roles as H2O2 scavengers and signaling players in response to abiotic stress and conclusive results are lacking. We tested the hypothesis that thylakoidal APX displays an ...
Expression of BMP ii by human osteoblasts cultivated on dense or porous titaniumExpressão da BMP ii por osteoblastos humanos cultivados sobre titânio denso ou poroso
(2018-01-01)
Objective: Modifications of titanium have been described as an important tool improving bone repair and boneimplant contact. The aim of this research was to quantified the expression of the morphogenetic bone protein II ...
Expanding the knowledge on lignocellulolytic and redox enzymes of worker and soldier castes from the lower termite Coptotermes gestroi
(2016-10-13)
Termites are considered one of the most efficient decomposers of lignocelluloses on Earth due to their ability to produce, along with its microbial symbionts, a repertoire of carbohydrate-active enzymes (CAZymes). Recently, ...
Komagataeibacter rhaeticus grown in sugarcane molasses-supplemented culture medium as a strategy for enhancing bacterial cellulose production
(2018-10-15)
Komagataeibacter rhaeticus, a bacterium isolated from Kombucha tea, was used to produce bacterial cellulose (BC) through its cultivation in a static sugarcane molasses (SCM) supplemented-culture medium (totally or partially), ...
Mitochondrial Sirtuin TcSir2rp3 Affects TcSODA Activity and Oxidative Stress Response in Trypanosoma cruzi
(2021-11-11)
Trypanosoma cruzi faces a variety of environmental scenarios during its life cycle, which include changes in the redox environment that requires a fine regulation of a complex antioxidant arsenal of enzymes. Reversible ...
Epigenetic therapy with inhibitors of histone methylation suppresses DNA damage signaling and increases glioma cell radiosensitivity
(2017-01-01)
Radiation therapy is widely used to treat human malignancies, but many tumor types, including gliomas, exhibit significant radioresistance. Radiation therapy creates DNA double-strand breaks (DSBs), and DSB repair is linked ...
Plasma immersion ion implantation (PIII) influence on Ti-6Al-4V alloy: Frequency effect
(2018-04-01)
The plasma immersion ion implantation treatment (PIII) acts to increase mechanical resistance with solid solution formation, new phases and defects inclusion, besides chemical and residual stress profile modification. ...
Supragingival and subgingival microbiota from patients with poor oral hygiene submitted to radiotherapy for head and neck cancer treatment
(2018-06-01)
Objective: This case-control study aimed to evaluate the effects of conventional radiotherapy (RT) on the prevalence and populations of oral microorganisms in head and neck cancer patients who did not receive adequate ...
Ciclo reprodutivo sazonal e variabilidade em níveis de testosterona no pato doméstico (Anas platyrhynchos)
(2017-01-01)
Morphofunctional gonadal alterations constitute an annual cycle in birds during which four phases can be distinguished in the testes based on histological modifications in the seminiferous epithelium, called quiescence, ...
Evaluation of a Titanium Surface Treated with Hydroxyapatite Nanocrystals on Osteoblastic Cell Behavior: An In Vitro Study
(Quintessence Publishing Co Inc, 2018-05-01)
Purpose: In the context of macrostructural and microstructural modifications to the design of dental implants, surface topography changes with different treatments have the purpose of accelerating bone formation. The aim ...
