Nanostructured screen-printed electrodes modified with self-assembled monolayers for determination of metronidazole in different matrices
(Sociedade Brasileira de Química, 2014-09-01)
This paper describes the development of a sensor for the determination of metronidazole using a simple method involving the creation of nanoporous structures on gold electrodes followed by modification with self-assembled ...
SnO2, ZnO and related polycrystalline compound semiconductors: An overview and review on the voltage-dependent resistance (non-ohmic) feature
(2008-01-01)
The present review describes mainly the history of SnO2-based voltage-dependent resistors, discusses the main characteristics of these polycrystalline semiconductor systems and includes a direct comparison with traditional ...
Ph-cycling models for in vitro evaluation of the efficacy of fluoridated dentifrices for caries control: Strengths and limitations
(2010-01-01)
Despite a plethora of in situ studies and clinical trials evaluating the efficacy of fluoridated dentifrices on caries control, in vitro pH cycling models are still broadly used because they mimic the dynamics of mineral ...
Chemoprophylaxis for contacts of leprosy patients: A systematic review and meta-analysis
(2018-07-01)
Individuals who are in close association or proximity with leprosy patients have a greater chance of acquiring the disease. However, the effectiveness of chemoprophylaxis in preventing leprosy in contacts of affected ...
Histocompatibility antigen, class i, g (Hla-g)’s role during pregnancy and parturition: A systematic review of the literature
(2021-10-01)
Introduction: Immune homeostasis of the intrauterine cavity is vital for pregnancy mainte-nance. At term or preterm, fetal and maternal tissue inflammation contributes to the onset of labor. Though multiple immune-modulating ...
Changes in cells's secretory organelles and extracellular matrix during endochondral ossification in the mandibular condyle of the growing rat
(1991)
The mandibular condyle from 20-day-old rats was examined in the electron microscope with particular attention to intracellular secretory granules and extracellular matrix. Moreover, type II collagen was localized by an ...
Amorphous ZrF4-a molecular dynamics study
(Elsevier B.V., 1993-09-01)
Using an effective two-body interaction potential, a molecular dynamics study of the structural properties of amorphous ZrF4 phase is presented. The effective pair potential includes steric repulsion, Coulomb interaction ...
Strategies to minimize heat stress in broilers chickens
(2014)
The objective of this study was to evaluate the application of early age thermal conditioning (TC) and dietary electrolyte balances (DEB) to minimize the effect of heat stress. A total of 240 Cobb 500 1-d-old male broiler ...
Dietary electrolytes and thermal conditioning: minimizing heat stress in broilers
(2013)
In tropical climates the heat is one of the major constraints to production of broilers and is responsible for inducing a high mortality, especially in the finishing phase. Thus, the objective of this study was to compare ...
Reações alérgicas aos implantes osseointegráveis de titânio: uma revisão de literatura
(2014)
Titanium dental implants have been common practice in the dental office, which can increases the number of allergic reactions to this material. Objectives: to alert dental surgeons and specialists of this possible phenomenon ...
