This study investigated the effects of yerba mate consumption, a South American beverage, on cardiac remodeling in rats. For this purpose, 24 male Wistar rats were divided into Control Group (CG) which received filtered water and a standard diet, and Yerba Mate Group (YM), 6 g of Ilex paraguariensis in 100 ml water and the same diet, for 30 days. The YM group showed a reduction in final body weight and food consumption without altering weight gain. Regarding cardiac remodeling, the YM group exhibited a decrease in the right ventricle weight/final body weight ratio, suggesting cardiac atrophy, without affecting the atria and left ventricle. There was no change in cardiomyocyte area or nuclear fractal dimension in both groups. However, animals that consumed yerba mate showed increased collagen deposition and a smaller fractal dimension in the left ventricle. The consumption of yerba mate at room temperature for 30 days induced changes in cardiac remodeling, as evidenced by increased collagen deposition and alterations in fractal dimension in the left ventricle.

To determine if reduced tree densities(number of trees per unit area) lead to changes in micro-meteorological and tree physiological characteristics, two areas with different tree densities were assessed. One was an agrosilvopastoral system(AGP) with low tree density, and the other, a secondary forest(SF) with greater tree numbers, both located in a semiarid region of Brazil. Data were collected simultaneously by two automated weather stations: rainfall, air(T_a) and soil temperatures(T_(s5 cm)), relative humidity(RHair), photosynthetically active radiation(PAR), soil moisture at two depths(M_(s30 cm)and M_(s50 cm)),and wind velocity(Vw). Net photosynthesis in Cordia oncocalyx Allema?o trees was measured with an infrared gas analyzer in February, March, May, July, August and September 2011, which encompasses a rainy period followed by a dry period. Average values of Ta, T_(s5 cm), Vwand PAR were greater and average values of RHairand M_(s50 cm) were lesser in the AGP. Photosynthetic rates were greater in plants growing under the AGP at the onset of the dry season when Vw, PAR and T_(s5 cm)were greater and M_(s50 cm) was lesser. Photosynthetic rates correlated strongly with physical parameters during the dry season, especially under SF. Differences in tree numbers between AGP and SF led to differences in physical environmental parameters;however, the latter had less influence on photosynthetic rates in C. oncocalyx during the rainy season. During the dry season, all physical parameters had an impact on net photosynthesis under SF but not under AGP. This indicates a certain independence of plants in AGP.

Intestinal neuronal dysplasia type B(IND-B) is a controversial entity among the gastrointestinal neuromuscular disorders. It may occur alone or associated with other neuropathies, such as Hirschsprung's disease(HD). Chronic constipation is the most common clinical manifestation of patients. IND-B primarily affects young children and mimics HD, but has its own histopathologic features characterized mainly by hyperplasia of the submucosal nerve plexus. Thus, IND-B should be included in the differential diagnoses of organic causes of constipation. In recent years, an increasing number of cases of IND-B in adults have also been described, some presenting severe constipation since childhood and others with the onset of symptoms at adulthood. Despite the intense scientific research in the last decades, there are still knowledge gaps regarding definition, pathogenesis, diagnostic criteria and therapeutic possibilities for IND-B. However, in medical practice, we continue to encounter patients with severe constipation or intestinal obstruction who undergo to diagnostic investigation for HD and their rectal biopsies present hyperganglionosis in the submucosal nerve plexus and other features, consistent with the diagnosis of IND-B. This review critically discusses aspects related to the disease definitions, pathophysiology and genetics, epidemiology distribution, clinical presentation, diagnostic criteria and therapeutic possibilities of this still little-known organic cause of intestinal chronic constipation.

Parrots are among the most popular pets in the world and they are also some of the most illegally traded, particularly in Brazil. Some computational tools were recently developed by researchers based on molecular databases for taxonomy support, forensic identification and conservation purposes. In this study, the DNA Surveillance platform was used to build an online database tool for molecular identification of Brazilian Psittacids using DNA sequences of six mitochondrial genes. To illustrate possible taxonomic issues of the online tool due to interspecific hybridization or unresolved taxonomy, we focused on Amazona aestiva that is considered as one of the most common parrots in Brazil, commonly bred as pets, and considered to be part of a species complex with Amazona ochrocephala from South America. We provide three curated sequence databases, which allow the species identification of individuals or tissue samples of birds of the Psittacidae family using mitochondrial DNA markers, and a comprehensive description of a taxonomic issue involving the A. ochrocephala complex. The results obtained corroborate previous studies suggesting that these species are not reciprocally monophyletic, due to either an ancient hybridization in central Brazil, or, they maybe just are morpho-varieties of the same species. Alternatively, if A. aestiva and A. ochrocephala were considered as sister species, the data could be interpreted either as a result of secondary contact or incipient speciation. Beyond the use of mtDNA for species identification, the high mtDNA haplotype diversity observed in A. aestiva indicates its potential use in discrimination of lineages that could be an important auxiliary tool to certify the captive origin of legally commercialized parrots.

Objective: To apply an intensive and multidisciplinary education protocol in order to decrease, improve, delay or cancel the beginning of neuropathy and the manifestation of lesions in diabetic patients. Methodology: This is a cross-sectional descriptive study carried out at the Diabetes Mellitus Outpatient Clinic and Ward of Santa Marcelina Hospital in Porto Velho. This research was based on cases of patients with Diabetes and Diabetics with Leprosy. The criteria used to include the patients were: being treated with insulin therapy, not to be amputated, being on high medication of the leprosy at the moment of the evaluation and to present nutritional risk classification by the screening. The population was divided into two groups of fifteen patients: eight diabetic patients, four male and four female. Seven diabetics associated with leprosy were 4 males and 3 females. The monofilament test (Semmes-Weinstein 10 g) was used as the classification basis. Results and Discussion: Group A, called the intensive care group, began diabetes education work with medical, nutritional and rehabilitation guidelines by a multidisciplinary team for an average period of 15 days in the ward and after discharged with biweekly monitoring. Group B, called conventional care, received the same guidelines in outpatient care and the monitoring followed the quarterly protocol. Both groups were evaluated and reassessed for a period of 180 days in the outpatient clinic. Group A consisted of 8 (100%) patients, 4 (50%) diabetics and 4 (50%) diabetics and leprosy patients. Conclusion: Intensive education in diabetes showed an improvement in the sensitivity, healing and nutritional status of the patients, leading to an improvement in quality of life and disability level, reducing or delaying the beginning of neurological complications. The protocol intensive method demonstrated a 100% improvement in patients in group A.

We are in the so-called nutritional transition, in which obesity and its comorbidities have emerged as an important research topic, and the information on food composition is fundamental to promote nutritional safety. Fructose is the sweetest carbohydrate, and this sweetness, along with its low cost, is the key factor for its use in commercial drinks and sweets. The global average consumption of fructose per capita has increased from 56 g/day in 1986 to 65 g/day in 2007. Experimental models associate high fructose intake with the development of obesity and induced insulin resistance. In recent studies, diabetic patients have been reported to use fructose more frequently than glucose. Fructose acts differently in the hypothalamus and generates less satiety than glucose;thus, fructose has a high lipogenic potential. Replacing fructose with another isocaloric carbohydrate is associated with better glycemic control.
