The Alzheimer's dementia (AD) is the most prevalent form of dementia in the elderly. Among the harmful changes arising from the DA, there may be sleep disturbance and impaired quality of life. Physical activity is an important non-pharmacological feature that would provide positive effects for the treatment of disease. However, there are still few studies that clarify the effects of resistance training in this population. Thus, the present study has as objective analyzes the effects of the resistance training in sleep disturbance and quality of life of patients with AD. Participated in this study 22 patients with clinical diagnosis of AD divided into two groups: Training Group (TG) and Social Interaction Group (SIG). The subjects of TG underwent a resistance training protocol, appropriate to the individual conditions, during three days no consecutive in the week, with duration of 60 minutes each session, for 16 weeks. The SIG won't participate in any systematized physical activity, but they realized other activities, such as reading, poetry, hiking and painting, among others. This protocol also was realized three times in week for 16 weeks, with duration of 60 minutes each session. Both groups were assessed at the beginning of the program and after 16 weeks. For the assessment of sleep disturbance was used the Mini Sleep Questionnaire and to assess of quality of life was used the Scale for Assessment of Quality of Life in Alzheimer's disease (QL), versions: patient, caregiver, family and the final score. Due to the scalar nature of the data and small sample, all variables were analyzed by nonparametric statistics. The U-Mann Whitney test, Wilcoxon test and Spearman correlation test was used, except for the Modified Baecke... (Complete abstract click electronic access below)

A contaminação do solo por metais potencialmente tóxicos constitui um dos principais problemas ambientais. Por meio da lixiviação e percolação das águas, esses metais podem ser mobilizados e vir a contaminar mananciais superficiais e subterrâneos, comprometendo sua qualidade. A biodisponibilização desses metais para as plantas e, a partir dessas, para o homem é outro desfecho negativo dessa situação. O cádmio é um elemento tóxico. Os teores encontrados nos solos costumam não oferecer riscos. Porém, esses teores são potencializados pela utilização de fertilizantes. O níquel pode ser carcinogênico em doses elevadas. Sua presença em fertilizantes fosfatados proporciona maiores concentrações do metal no solo. É amplo o registro sobre efeitos do excesso desses metais, tanto em plantas, quanto em animais e no ser humano. O manganês é um dos elementos mais abundantes na crosta terrestre e se encontra largamente distribuído em solos, sedimentos, rochas, água e materiais biológicos. Contrariamente aos dois metais anteriores, esse micronutriente é um elemento essencial ao ser humano. Sua carência causa inúmeras enfermidades, por outro lado, seu excesso também. Nesse caso, poucos são os relatos sobre o assunto. Nesse estudo foram utilizados métodos de extração de metais de fertilizantes e se constatou que, quando presentes, os metais cádmio e níquel apresentaram concentrações proibitivas o que é motivo de preocupação e demonstra a falta de controle sobre a indústria de insumos agrícolas. Para o manganês não há parâmetros orientadores com limites de teores, mas com certeza, são necessários trabalhos nesse sentido para se evitar seu consumo indiscriminado.

Objective: To review the cardiovascular consequences of obstructive sleep-disordered breathing in children Data source: Medline and Ovid data base. Study selection: pediatric articles (original articles and case report) that investigated the obstructive sleep-disordered breathing in children Data synthesis: The obstructive sleep-disordered breathing can lead to serious cardiovascular consequences such as pulmonary hypertension, pulmonary edema and anatomic and functional abnormalities Conclusions: The knowledge of cardiovascular repercussions allows in better management of pediatric patients and may result in positive consequences for treatment and follow up of these patients.

The photopolimerization it is be widely used nowadays in different fields as materials, medicine and dentistry. To occur that synthesis is utilized dimethacrylates monomers and photoinitiators, the photoinitiator system more usual is camphorquinone/tertiary amine (ethyl-p-dimethylamino benzoate). However is knowledge that tertiary amines are toxics, so the aim of this work is replace toxic amine compounds to non-toxic compounds as glycerol and inositol. Therefore was used the FTIR technic to calculate the monomers conversion degree as well as Thermogravimetric Analysis-simultaneous differential thermal analysis (TG-DTA) and Differential Scanning Calorimetry (DSC) to evaluate thermal stability, combustion rate, degradation steps, oxidation and volatilization of all samples. The study shown no significant difference about thermal behavior of all polymers, the initiators system for efficient and more fastness was camphorquinone /tertiary amine system followed by ca mph o r quinone/glycerol system

Cintra stream is the major receiver of treated effluent from sanitary, hospital and research laboratory sewage from the UNESP campus in Botucatu, Rubião Júnior District, São Paulo state; and it has shown evidence of diffuse contamination by metals along it. Analyses of the most toxic metals (Pb, Cu, Fe, Ni and Zn) were carried out by using an atomic absorption spectrometer AA-6.800 - Perkin Elmer, analyst 700. ANOVA followed by the Tukey test were used for data analyses at 5% significance level. The main objective of this study was to compare current data on metal levels with data from other studies, in the same area, and of the same nature, conducted before and after implementation of chemical residue management by the university in 2008. Also, it aimed at identifying and quantifying possible diffuse and punctual contamination. Sites S1 and S2 showed punctual contamination, while diffuse sources were observed between S4 and S5. The quality of water in the Cintra Stream improved after establishment of the program of laboratory chemical residue management in the Campus of UNESP.

Pet animals are closer to their owners and for this reason erroneously share the same alimentation. Several substances can cause intoxication or poisoning in dogs and cats, being many of those also found in human food. Some foods that are edible for humans or even to other animal species can be risky for dogs and cats due to different metabolic pathways, and further damage can be caused depending on the amount or concentration consumed. Poisoning in animals occur intentionally or accidentally in the household of its owner, occurring acute onset of clinical signs. Thus, the objective of this review was to present the food products for humans that cannot be given to dogs and cats as well as clinical signs characteristic of a toxicosis, also demonstrating the therapy for the damage created by consumption of those substances. This review explores the mechanisms of action and clinical signs of toxicosis caused by chocolate, xylitol, macadamia nuts, onions, garlic, grapes and raisins, avocado, alcoholic beverages and milk.
