Background: Burning mouth syndrome (BMS) it is characterized by burning and uncomfortable sensations with no clinical alterations or laboratory findings. The evaluation of the salivary characteristics of people with BMS can help the understanding of the pathogenesis of this condition. This case-control study aimed to trace the salivary profile of women with burning mouth syndrome (BMS).

Background & Aims: Obesity is increasing worldwide. Resveratrol appears as a substance capable of helping with weight loss. This study aimed to investigate the resveratrol effect in the treatment of obesity in general population.

Maternal and child health inequalities among migrants: the case of Haiti and the Dominican Republic.

Objective: To assess coverage and inequalities in maternal and child health interventions among Haitians, Haitian migrants in the Dominican Republic and Dominicans.

Methods: Cross-sectional study using data from nationally representative surveys carried out in Haiti in 2012 and in the Dominican Republic in 2014. Nine indicators were compared: demand for family planning satisfied with modern methods, antenatal care, delivery care (skilled birth attendance), child vaccination (BCG, measles and DPT3), child case management (oral rehydration salts for diarrhea and careseeking for suspected pneumonia), and the composite coverage index.

Synthesis and characterization of monoacylglycerols through glycerolysis of ethyl esters derived from linseed oil by green processes.

The synthesis of monoacylglycerol (MAG) through the glycerolysis of ethyl ester mixture (biodiesel) was investigated in this study from linseed oil, low-cost alternative feedstock, using an alkaline catalyst with green reagent. The transesterification double step process (TDSP), reaction with ethanol to ethyl esters yielded 97%. In the glycerolysis reaction, the optimum operating condition was in a temperature of 130 °C with 5% sodium hydroxide (NaOH) in 1 : 5 biodiesel-glycerol and 12 h reaction time, in open reactor.

Frequency of infection in cervical intraepithelial lesions and the status of cytological p16/Ki-67 dual-staining.

Background: (Ct) is not a disease subject to mandatory reporting in Brazil, and the prevalence rate of this genital infection varies according to the region in which studies are conducted, as well as by the detection technique employed. Ct has been associated with persistence of Human papillomavirus (HPV) infection and the facilitation of cervical carcinoma development. We evaluated the infection and its association with cytology, p16/Ki-67 dual-stained cytology and cervical intraepithelial lesions status in a screening cohort in Brazil.

RNAi Efficiency, Systemic Properties, and Novel Delivery Methods for Pest Insect Control: What We Know So Far.

In recent years, the research on the potential of using RNA interference (RNAi) to suppress crop pests has made an outstanding growth. However, given the variability of RNAi efficiency that is observed in many insects, the development of novel approaches toward insect pest management using RNAi requires first to unravel factors behind the efficiency of dsRNA-mediated gene silencing. In this review, we explore essential implications and possibilities to increase RNAi efficiency by delivery of dsRNA through non-transformative methods.

Emerging Technologies to Create Inducible and Genetically Defined Porcine Cancer Models.

There is an emerging need for new animal models that address unmet translational cancer research requirements. Transgenic porcine models provide an exceptional opportunity due to their genetic, anatomic, and physiological similarities with humans. Due to recent advances in the sequencing of domestic animal genomes and the development of new organism cloning technologies, it is now very feasible to utilize pigs as a malleable species, with similar anatomic and physiological features with humans, in which to develop cancer models.

Dioclea violacea lectin ameliorates oxidative stress and renal dysfunction in an experimental model of acute kidney injury.

Acute kidney injury (AKI) is characterized by rapid and potentially reversible decline in renal function; however, the current management for AKI is nonspecific and associated with limited supportive care. Considering the need for more novel therapeutic approaches, we believe that lectins from Dioclea violacea (Dvl), based on their anti-inflammatory properties, could be beneficial for the treatment of AKI induced by renal ischemia/reperfusion (IR). Dvl (1 mg/kg, i.

Application of genomics-assisted breeding for generation of climate resilient crops: progress and prospects.

Climate change affects agricultural productivity worldwide. Increased prices of food commodities are the initial indication of drastic edible yield loss, which is expected to increase further due to global warming. This situation has compelled plant scientists to develop climate change-resilient crops, which can withstand broad-spectrum stresses such as drought, heat, cold, salinity, flood, submergence and pests, thus helping to deliver increased productivity.

Influence of age on postural sway during different dual-task conditions.

Dual-task performance assessments of competing parallel tasks and postural outcomes are growing in importance for geriatricians, as it is associated with predicting fall risk in older adults. This study aims to evaluate the postural stability during different dual-task conditions including visual (SMBT), verbal (CBAT) and cognitive (MAT) tasks in comparison with the standard Romberg's open eyes position (OE). Furthermore, these conditions were investigated in a sample of young adults and a group of older healthy subjects to examine a potential interaction between type of secondary task and age status.

Self-controlled learning: the importance of protecting perceptions of competence.

Recent studies examining the role of self-controlled feedback have shown that learners ask for feedback after what they believe was a "good" rather than "poor" trial. Also, trials on which participants request feedback are often more accurate than those without feedback. The present study examined whether manipulating participants' perception of "good" performance would have differential effects on learning.

Reduced frequency of knowledge of results enhances learning in persons with Parkinson's disease.

Parkinson's disease (PD) is a progressive neurological disorder, known to cause a large number of motor and non-motor limitations. Research related to factors that affect motor control and learning in people with PD is still relatively limited. The purpose of this study was to compare the effects of different frequencies (100 versus 66%) of knowledge of results (KR) on the learning of a motor skill with spatial demands in participants with PD.
