Distribution pattern and relative abundance of the agricultural rodent pests of rain-fed and irrigated areas of district Swat Khyber Pakhtunkhwa, Pakistan were recorded from April 2011 to November 2013 using wire mesh live traps. A total of 350 rodents (269 Rattus rattus and 81 Mus musculus) were captured under 2268 trap nights (trap success 0.15). Regression of daily captures on cumulative captures revealed an estimate of 350 rodents from all the sampled structures with an average of 21.8 rodents per crop field. House rats (R. rattus; 76.8% of captures) were numerically dominant in almost all types of agricultural fields, and were significantly different from the mice (Mus musculus; 23.1% of captures). Both species were found together in some fields. The sex ratio revealed that males outnumbered the females in both of the reported species.Caryocar brasiliense Camb. Apoptosis inhibitor (Malpighiales Caryocaraceae) trees have a wide distribution in the Cerrado, and it is protected by federal laws. The need to monitor and understand pest damage to crops and forests is a major motivation for the study of population distribution. The mites (Acari) population distributions on C. brasiliense are unknown. We studied seasonal mite population distribution and their ecological indices on C. brasiliense trees in Cerrado areas during three years. Greatest number of Agistemus sp. (Stigmaeidae), Histiostoma sp. (Histiostomidae), Proctolaelaps sp. link2 (Ascidae), and diversity and species richness on leaves of C. brasiliense occurred in the autumn; Tetranychus sp.1 (Tetranychidae) on leaves in the autumn and winter; Histiostoma sp., and Proctolaelaps sp. in fruits in the summer. No significant effect of season was observed in the abundance of Eutetranychus sp., Tetranychus sp.2 (Tetranychidae) and Acaridae. The populations of Acaridae, Eutetranychus sp., Proctolaelaps sp. and Tetranychus sp.1 negatively correlated with temperature. Proctolaelaps sp. and Tetranychus sp.1 correlated negatively with rainfall and Eutetranychus sp. and Proctolaelaps sp. positively with sunlight. The period with low rainfall and relative humidity increases the phytophagous mites and their predators, especially Agistemus sp.. The Tetranychus sp. and Histiostoma sp. species may become pests in C. brasiliense in the Cerrado domain.Exposure to the hight-fat diet may alter the control of food intake promoting hyperphagia and obesity. The objective of this study was to investigate the effects of this diet on dopamine receptors (drd1 and drd2), proopiomelanocortin (pomc), neuropeptideY (npy) genes expression, and preference food in adult rats. Wistar female rats were fed a hight-fat or control diet during pregnancy and lactation. The offspring were allocated into groups Lactation - Control (C) and High-fat (H). Post-weaning - Control Control (CC), offspring of mothers C, fed a control diet after weaning; Control Hight-fat (CH), offspring of mothers C, fed a hight-fat diet after weaning; Hight-fat Control (HC), offspring of mothers H, fed with control diet after weaning; and Hight-fat Hight-fat (HH), offspring of mothers H, fed a H diet after weaning. The groups CH and HH presented greater expression of drd1 in comparison to the CC. The drd2 of CH and HC presented higher gene expression than did CC. HH presented higher pomc expression in comparison to the other groups. HC also presented greater expression in comparison to CH. The npy of HH presented greater expression in relation to CH and HC. HH and HC have had a higher preference for a high-fat diet at 102º life's day. The high-fat diet altered the gene expression of the drd1, drd2, pomc and npy, and influencing the food preference for high-fat diet.Autism spectrum disorder is associated with alterations in GABAergic and glutamatergic neurotransmission. Here, we aimed to determine the concentration of GABA, glutamate, glutamine, aspartate, taurine, and glycine in brain tissue and plasma of rats prenatally exposed to valproic acid (VPA), a well-characterized experimental model of autism. Pregnant rats were injected with VPA (600mg/Kg) during the twelfth-embryonic-day. Control rats were injected with saline. On the fourteen-postnatal-day, rats from both groups (males and females) were anesthetized, euthanized by decapitation and their brain dissected out. The frontal cortex, hippocampus, amygdala, brain stem and cerebellum were dissected and homogenized. Homogenates were centrifuged and supernatants were used to quantify amino acid concentrations by HPLC coupled with fluorometric detection. Blood samples were obtained by a cardiac puncture; plasma was separated and deproteinized to quantify amino acid concentration by HPLC. We found that, in VPA rats, glutamate and glutamine concentrations were increased in hippocampus and glycine concentration was increased in cortex. link3 We did not find changes in other regions or in plasma amino acid concentration in the VPA group with respect to control group. Our results suggest that VPA exposure in utero may impair inhibitory and excitatory amino acid transmission in the infant brain.The functionalization of polysaccharides with synthetic nanopolymers has attracted great attention owing to the applications of this method in many industrial fields. This work aimed to investigate the effect of arsenic trioxide on the functionalization of dextran. Dextran-arsenite nanoparticle formation was induced by microwave with sulfuric acid as a catalyst. Various analytical techniques were used to verify the structure of the nanopolymers. Besides, various reaction conditions, such as dextran concentration, arsenic trioxide concentration and pH, were investigated to determine their impact on particle size. The results indicated that the product was an arsenite-based nanomaterial retaining the basic configuration of dextran and that the product size was positively correlated with pH but negatively correlated with arsenic trioxide concentration. Moreover, the inhibitory effects of the dextran-arsenite nanoparticles on the growth of the human colorectal cancer cell line HCT-116 and human hepatoma carcinoma cell lines Huh-7 and SMMC-7721 were studied. The results showed that the product could inhibit the proliferation of these three tumor cell lines in a dose-dependent manner. Therefore, the product could be a new type of functional nanomaterial for further study on the synthesis, biological activity and development of polysaccharide drugs.Potimirim is one of the 40 genera of Atyidae restricted to America, which occurs in coastal freshwater habitats and questions about population status and variability have been emerging. Potimirim brasiliana occurs in Brazil from the northeastern to southeastern region. In order to evaluate the hypothesis of genetic structure among populations, we performed molecular analyses with specimens from all known limit of distribution of the species. The molecular markers used were COI and 28S. Phylogenetic trees were obtained by maximum likelihood and Bayesian analyses, and a haplotype network was obtained based only on COI. We found clear separation between P. brasiliana, P. potimirim, P. glabra and Potimirim sp 2. No pattern of structuration was found among P. brasiliana, but the haplotype network showed geographic pattern of structuration for the congener P. potimirim. The lack of genetic structuration among P. brasiliana can be explained by its life cycle that requires brackish water to complete their larval development. The larvae and juvenile in contact with these habitats can spread through oceanic currents, especially in higher rainfall seasons, maintaining the gene flow. The explanation for the geographical pattern found among P. potimirim is still missing and aspects about its lifecycle and larval development should be investigated.
To describe cases of human rabies in Ceará State, Brazil between 1970 and 2019.
This was a descriptive study using secondary data from the Ceará State Department of Health and the state reference hospital.
Of 171 cases, 75.7% occurred in males, 60.0% in <19-year-olds, and 56.0% in urban areas. Rabies was transmitted by dogs in 74.0% of cases, marmosets in 16.7% and bats in 7.3%. Between 1970 and 1978, there was an increase of cases (using the Joinpoint Regression Program, annual percentage change [APC] = 13.7 - 95%CI 4.6;41.5), while between 1978 and 2019 there was a decrease (APC = -6.7 - 95%CI -8.8;-5.9). There was a reduction in transmission by dogs (71 cases, last case in 2010) and an increase by sylvatic animals (5 cases since 2005).
This study demonstrates changes in rabies transmission dynamics during the period studied, with a reduction in transmission by dogs and an increase of transmission by sylvatic animals.

To analyze association between dental pain, use of dental services and school absenteeism in Brazilian adolescents.
This was a cross-sectional study with data from the National School Health Survey (PeNSE 2015). The study's dependent variable was school absenteeism due to health reasons in the last 12 months. Socioeconomic characteristics, dental pain and use of dental services were the independent variables evaluated. Logistic regression was used to estimate odds ratios (OR) and respective 95% confidence intervals (95%CI).
Data on 102,072 schoolchildren were included. Absenteeism prevalence due to health reasons was 53.7% (95%CI 53.2;54.3). In the adjusted analysis, there was association between dental pain and school absenteeism (OR=1.35 - 95%CI 1.26;1.45), and an increase in absenteeism occurrence the greater the number of dental visits.
The results suggest that dental pain and frequency of dental visits may be related to school absenteeism.
