Alimentos tóxicos para cães e gatos

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.

Vinhos de mesa varietais de uvas americanas: análises químicas e energética

The Brazilian wine industry has a remarkable characteristic that distinguishes from other markets, while the foreign market only accepts products originating from European varieties (Vitis vinifera), in Brazil, products originating from American varieties (Vitis labrusca and Vitis bourquina) and hybrids are also accepted. Dry and sweet varietal wines from varieties Bordô (dry and sweet), Isabel (sweet) e Máximo (dry) were analyzed, by the following chemical standard analyses: alcohol content; density; total and reduced dry matter; alcohol/reduced dry extract ratio; reducing sugars; total, volatile and fixed acidity; pH; total and free sulfur dioxide; and energy value. All analyzed wines presented results within the parameters set forth by Brazilian law, a positive fact, once they are commercialized. The varietal wine Máximo presented a low content of total and free sulfur dioxide, which may cause future problems with its sanity.

Cardiovascular risk among health professionals working in pre-hospital care services

The objective of this study was to assess the cardiovascular risk factors among health professionals, particularly hypertension, and stratify them according to the Framingham Risk Score (FRS). The participants were 154 professionals working in pre-hospital care in Sao Paulo, Brazil, and on the Br-116 highway. Values were considered significant for p<0.05. The prevalence of hypertension was 33%, 20.1% were smokers, 47% consumed alcoholic beverages, 64% were sedentary, 66% were obese/overweight and 70% had an altered abdominal circumference. In terms of laboratory values: glucose >= 110mg/dL11%, total cholesterol >= 200mg/dL-36%, LDL-c >= 130mg/dL-33%, HDL-c<60mg/dL89%, triglycerides >= 150mg/dL-30% and C reactive protein >= 0.5mg/dL-16%. The FRS was average in 10.3% and high in 1.3%. In logistic regression analysis, it was verified that hypertension was associated with: HDL-c (odds ratio: 0.257,) and FRS (odds ratio: 23.159). There was strong correlation between hypertension and FRS. Data are noteworthy, as this is a relatively young sample of health professionals.

IDENTIFICATION OF ETHANOLIC WOOD EXTRACTS USING ELECTRONIC ABSORPTION SPECTRUM AND MULTIVARIATE ANALYSIS

IDENTIFICATION OF ETHANOLIC WOOD EXTRACTS USING ELECTRONIC ABSORPTION SPECTRUM AND MULTIVARIATE ANALYSIS. The application of multivariate analysis to spectrophotometric (UV) data was explored for distinguishing extracts of cachaca woods commonly used in the manufacture of casks for aging cachacas (oak, cabretiva-parda, jatoba, amendoim and canela-sassafras). Absorbances close to 280 nm were more strongly correlated with oak and jatoba woods, whereas absorbances near 230 nm were more correlated with canela-sassafras and cabretiva-parda. A comparison between the spectrophotometric model and the model based on chromatographic (HPLC-DAD) data was carried out. The spectrophotometric model better explained the variance data (PC1 + PC2 = 91%) exhibiting potential as a routine method for checking aged spirits.

Uso de substâncias na adolescência e problemas familiares

Esta pesquisa visou a avaliar a associação entre o consumo de substâncias (álcool, tabaco e drogas ilícitas) e problemas familiares numa amostra de 965 adolescentes em 50 escolas públicas de dois municípios do Estado de São Paulo, Brasil, em 2007. Foi utilizado o Drug Use Screening Inventory (DUSI) para a coleta de dados. O uso de álcool, tabaco e drogas ilícitas foi associado à avaliação negativa da relação familiar, à falta de suporte/monitoramento e ao uso de substâncias por familiares (p < 0,05). Os estudantes que relataram ter feito uso de substâncias apresentaram mais problemas familiares do que aqueles que não consumiram nenhuma substância (p < 0,001). Os adolescentes que usaram álcool e tabaco (p = 0,028) e drogas ilícitas (p < 0,001) relataram ter mais problemas familiares do que aqueles que usaram apenas álcool. Os resultados apontam para a importância de se ficar atento ao consumo de álcool e tabaco entre os adolescentes, já que o relato do consumo das duas substâncias esteve associado a prejuízos familiares significativos, semelhantes ao uso de drogas ilícitas.

beta(1) Adrenergic receptor is key to cold- and diet-induced thermogenesis in mice

Brown adipose tissue (BAT) is predominantly regulated by the sympathetic nervous system (SNS) and the adrenergic receptor signaling pathway. Knowing that a mouse with triple beta-receptor knockout (KO) is cold intolerant and obese, we evaluated the independent role played by the beta(1) isoform in energy homeostasis. First, the 30 min i.v. infusion of norepinephrine (NE) or the beta(1) selective agonist dobutamine (DB) resulted in similar interscapular BAT (iBAT) thermal response in WT mice. Secondly, mice with targeted disruption of the beta(1) gene (KO of beta(1) adrenergic receptor (beta 1KO)) developed hypothermia during cold exposure and exhibited decreased iBAT thermal response to NE or DB infusion. Thirdly, when placed on a high-fat diet (HFD; 40% fat) for 5 weeks, beta 1KO mice were more susceptible to obesity than WT controls and failed to develop diet-induced thermogenesis as assessed by BAT Ucp1 mRNA levels and oxygen consumption. Furthermore, beta 1KO mice exhibited fasting hyperglycemia and more intense glucose intolerance, hypercholesterolemia, and hypertriglyceridemia when placed on the HFD, developing marked non-alcoholic steatohepatitis. In conclusion, the beta(1) signaling pathway mediates most of the SNS stimulation of adaptive thermogenesis. Journal of Endocrinology (2012) 214, 359-365

Strength training improves plasma parameters, body composition and liver morphology in ovariectomized rats

Objective. - The aim of this study was to identify the effects of strength training on plasma parameters, body composition and the liver of ovariectomized rats. Methods. - Wistar sedentary (SHAM), ovariectomized (OVX), and ovariectomized trained rats (strength training [OVX-EXE]) of 85% of one maximal repetition (1 RM), three times per week, for 10 weeks, were used on this study. We monitored the body weight and visceral (uterine, mesenteric and retroperitoneal) and subcutaneous adiposity, total cholesterol, triglycerides, HDL, blood glucose and liver morphology to identify the presence of macrovesicular steotosis (haematoxylin and eosin staining). Results. - We observed that strength training changed body weight (SHAM 293.0 +/- 14.5 g; OVX 342.6 +/- 10.8 g; OVX-EXE 317.7 +/- 11.9 g, P < 0.05), visceral and subcutaneous adiposity, glucose (SHAM 111.2 +/- 10.0 mg/dL; OVX 147.4 +/- 18.8 mg/dL; OVX-EXE 118.5 +/- 2.2 mg/dL, P < 0.05), increased HDL (SHAM 82.7 +/- 1.4 mg/dL; OVX 64.6 +/- 2.8 mg/dL; OVX-EXE 91.4 +/- 2.6 mg/dL, P < 0.05) and reduced macrovesicular steatosis in liver tissue. Conclusions. - Considering the data obtained in this research, we emphasise the use of strength exercise training as a therapeutic means to combat or control the metabolic disturbances associated with menopause, including adiposity, and adverse changes in blood glucose, blood HDL and macrovesicular steatosis.

Conductive polymer gas sensor for quantitative detection of methanol in Brazilian sugar-cane spirit

A low-cost chemiresistive gas sensor is described, made by the deposition of a thin film of a conductive polymer, poly(2-dodecanoylsulfanyl-p-phenylenevinylene), doped with dodecylbenzenesulfonic acid (10%, w/w), onto interdigitated electrodes. The sensor exhibits linear electrical conductance changes in function of the concentration of methanol present in sugar-cane spirit in the range between 0.05% and 4.0%. Since the sensor is cheap, easy to fabricate, durable, presents low power consumption, and is not sensitive to ethanol, acetic acid or water, it can be used in portable equipments for monitoring methanol levels in distilled alcoholic beverages such as Brazilian sugar-cane spirit (cachaca).

Ethyl carbamate kinetics in double distillation of sugar cane spirit

The aim of this study was to verify the effect of a double distillation on the reduction of the ethyl carbamate content in sugar cane spirit. Ethyl carbamate is a potentially carcinogenic compound normally present at critical levels in sugar cane spirit, constituting a public health problem and therefore hindering the export of this beverage. The ethanol, copper and ethyl carbamate contents were evaluated, using gas chromatography/mass spectroscopy, during a double distillation of the fermented sugar cane juice. The distillate fraction from the first distillation accumulated 30% of the ethyl carbamate formed. In the second distillation, the ethyl carbamate and the copper content increased during the process as the alcohol content decreased, and only 3% of the ethyl carbamate formed was collected in the spirit. Double distillation decreased the ethyl carbamate content in the sugar cane spirit by 97%. (C) Copyright 2012 The Institute of Brewing & Distilling

Ultrasonographic and laboratory markers of metabolic and cardiovascular disease risk in obese women with polycystic ovary syndrome

Objective To evaluate whether the presence of polycystic ovary syndrome (PCOS) alters multiple ultrasonographic and laboratory markers of metabolic and cardiovascular disease risk in obese women without any other health condition that could interfere with combined oral contraceptive (COC) eligibility criteria. Methods This was a case- control study evaluating 90 obese women ( body mass index ( BMI) = 30.0 kg/m2 and < 40 kg/m2) aged between 18 and 40 years without any other health condition that could interfere with COC eligibility criteria, of whom 45 had PCOS and 45 were age- matched controls. BMI, waist and hip circumference, arterial blood pressure, fasting insulin and glucose, quantitative insulin sensitivity check index ( QUICKI), highdensity lipoprotein cholesterol, low- density lipoprotein cholesterol, total cholesterol, triglycerides, testosterone, sex hormone- binding globulin, free androgen index ( FAI), carotid stiffness index, intima media thickness, flowmediated dilatation ( FMD) of the brachial artery and non- alcoholic fatty liver disease ( NAFLD) were assessed. Results In women with PCOS, we observed a higher frequency of NAFLD ( 73.3 vs. 46.7%, P < 0.01) and higher FAI ( 10.4 vs. 6.8%, P < 0.01). We also observed a trend towards increased insulin levels ( 10.06 +/- 6.66 vs. 7.45 +/- 5.88 mu IU/mL, P = 0.05), decreased QUICKI ( 0.36 +/- 0.06 vs. 0.39 +/- 0.07, P = 0.05) and decreased FMD ( 7.00 +/- 3.87 vs. 8.41 +/- 3.79%, P = 0.08). No other significant difference was observed. Conclusions NAFLD is frequent in obese women without any other health condition that could interfere with COC eligibility criteria, especially in those with PCOS. This should be considered when choosing the best contraceptive option. Copyright (C) 2012 ISUOG. Published by John Wiley & Sons, Ltd.
