Predictors for Moderate to Severe Acute Postoperative Pain after Cesarean Section.

Moderate to severe postoperative pain affects performance of daily activities and it contributes to persistent postoperative pain. In patients submitted to cesarean section, this pain can also interfere with women's ability to care for their babies, to effectively breastfeed, and to satisfactorily interact with their children. Factors influencing the pain perception during the immediate postoperative period have not been widely pursued.

Regional disparities in road traffic injuries and their determinants in Brazil, 2013.

Background: In recent decades middle-income countries have experienced a rapid increase in the number of cars and motorcycles. Increased deaths and hospitalizations due to road traffic injuries (RTI) has been observed in several countries as a result. In this study we assessed the determinants of RTIs in Brazil by mode of transportation and compared differences in RTI rates among macro-regions.

Chemical and physical strategies in onychomycosis topical treatment: A review.

Onychomycosis is a fungal infection of the fingernails or toenails caused by dermatophytes, nondermatophytes, moulds, and yeasts. This condition affects around 10-30% people worldwide, negatively influencing patients' quality of life, with severe outcomes in some cases. Since the nail unit acts as a barrier to exogenous substances, its physiological features hampers drug penetration, turning the onychomycosis treatment a challenge.

Discovery of New Anti-Schistosomal Hits by Integration of QSAR-Based Virtual Screening and High Content Screening.

Schistosomiasis is a debilitating neglected tropical disease, caused by flatworms of Schistosoma genus. The treatment relies on a single drug, praziquantel (PZQ), making the discovery of new compounds extremely urgent. In this work, we integrated QSAR-based virtual screening (VS) of Schistosoma mansoni thioredoxin glutathione reductase (SmTGR) inhibitors and high content screening (HCS) aiming to discover new antischistosomal agents.

The Identification of Microdeletion and Reciprocal Microduplication in 22q11.2 Using High-Resolution CMA Technology.

The chromosome 22q11.2 region has long been implicated in genomic diseases. Some genomic regions exhibit numerous low copy repeats with high identity in which they provide increased genomic instability and mediate deletions and duplications in many disorders.

Genetic relationships among freshwater mussel species from fifteen Amazonian rivers and inferences on the evolution of the Hyriidae (Mollusca: Bivalvia: Unionida).

The current phylogenetic framework for the South American Hyriidae is solely based on morphological data. However, freshwater bivalve morphology is highly variable due to both genetic and environmental factors. The present study used both mitochondrial (COI and 16S) and nuclear (18S-ITS1) sequences in molecular phylogenetic analyses of nine Neotropical species of Hyriidae, collected from 15 South American rivers, and sequences of hyriids from Australia and New Zealand obtained from GenBank.

Memory effects of sedative drugs in children and adolescents--protocol for a systematic review.

Background: Some sedatives used in children and adolescents can affect memory function. Memory impairment of traumatic experience can minimize the chance of future psychological trauma. Knowledge about the potential of different sedatives to produce amnesia can help in the decision-making process of choosing a sedative regimen.

Mycobacterium sherrisii Lung Infection in a Brazilian Patient with Silicosis and a History of Pulmonary Tuberculosis.

Nontuberculous mycobacteria (NTM) diseases became relevant with the emergence and spread of HIV and are also related to lung infection in non-HIV individuals with structural lung diseases. Mycobacterium sherrisii is a NTM first characterized in 2004. Only a few cases have been reported.

Nursing Assessment Tool for People With Liver Cirrhosis.

The aim of this study was to describe the process of developing a nursing assessment tool for hospitalized adult patients with liver cirrhosis. A descriptive study was carried out in three stages. First, we conducted a literature review to develop a data collection tool on the basis of the Conceptual Model of Wanda Horta.

Medical student stress: an elective course as a possibility of help.

Background: The frequently observed stress of medical students worldwide leads them to have psychic suffering often leading to illness. Minor psychic disorders such as anxiety, depression and burnout, have a higher prevalence in these students than in the rest of random population. Different initiatives were tried to minimize the deleterious effects of the medical course and this article aims at showing the repercussions of a elective course that and was proposed as a possibility to help the students.

A new species of monadal coral snake of the genus Micrurus (Serpentes, Elapidae) from western Amazon.

We described a new species of monadal coral snake of the genus Micrurus from the region of Tabatinga and Leticia, along the boundaries of Brazil, Colombia, and Peru. The new species can be distinguished from the other congeners by the combination of the following characters: absence of a pale nuchal collar; black cephalic-cap extending from rostral to firstdorsal scale and enclosing white tipped prefrontal scales; upper half of first to four supralabials and postoculars black; tricolor body coloration, with 27-31 black rings bordered by narrower white rings and 27-31 red rings; tail coloration similar to body, with alternating black rings bordered by irregular narrow white rings, red rings of the same width as the black rings; ventral scales 205-225; subcaudal scales 39-47.

Liposomal voriconazole (VOR) formulation for improved ocular delivery.

Treating infectious eye diseases topically requires a drug delivery system capable of overcoming the eye's defense mechanisms, which efficiently reduce the drug residence time right after its administration, therefore reducing absorption. In order to try to surpass such administration issues and improve life quality for patients with fungal keratitis, liposomal voriconazol (VOR) formulations were prepared. Formulations were composed of soy phosphatidylcholine (PC) containing or not 1,2-dioleoyl-3-trimethylammonium-propane (DOTAP) and cholesterol.

Methods: A systematic review was carried out in accordance with PRISMA Statement. The search encompassed the MEDLINE and LILACS databases and was executed during March 2012 using the keyword sarcopenia.

(Myrtaceae) fruits protect HEPG2 cells against carbon tetrachloride-induced toxicity.

(Myrtaceae) is an antioxidant compounds-rich Brazilian fruit popularly known as . In view of this, it was evaluated the hepatoprotective effects of pulp (GPE) or peel/seed (GPSE) hydroalcoholic extracts of on injured liver-derived HepG2 cells by CCl (4 mM). The results showed the presence of total phenolic in GPSE was (60%) higher when compared to GPE, associated with interesting antioxidant activity using DPPH• assay.

Morphological variation and taxonomy of Atractus latifrons (Günther, 1868) (Serpentes: Dipsadidae).

As currently understood Atractus latifrons is widely distributed in South America, occurring from Suriname to the east of the Andes in Bolivia. Throughout this widespread distribution, at least three distinct color patterns were previously reported in the literature. Here, we test whether quantitative variation and qualitative distribution of morphological characters are correlated with any color pattern displayed by the species along its range.

Virtual screening strategies in medicinal chemistry: the state of the art and current challenges.

Virtual screening (VS) techniques are well-established tools in the modern drug discovery process, mainly used for hit finding in drug discovery. The availability of knowledge of structural information, which includes an increasing number of 3D protein structures and the readiness of free databases of commercially available smallmolecules, provides a broad platform for VS. This review summarizes the current developments in VS regarding chemical databases and highlights the achievements as well as the challenges with an emphasis on a recent example of the successful application for the identification of new hits for sterol 14α-demethylase (CYP51) of Trypanosoma cruzi.

In silico prediction of drug metabolism by P450.

In the drug discovery cascade, metabolism studies should be performed as early as possible to allow an early evaluation of the metabolism profiles of drug candidates. To help design new drug candidates with improved pharmacokinetics, the knowledge of the site of metabolism is necessary. Computational or in silico metabolism approaches can be broadly classified into (i) ligand-based methods, and (ii) structure-based methods.
