Abstract: This study evaluated the effect of smoking and the presence of aromatic herbs on the quality of freshwater prawns muscle (Macrobrachium rosenbergii), through the analysis of sensory characteristics and proximate composition. Fifty-five freshwater thermally stunned prawns, with average weight of 33.9 ± 13.49g, were used. After cephalothoraxes and carapaces removal, the freshwater prawns were washed, weighed, identified, immersed in brine solution (20%) and then smoked at a temperature of 50 to 90°C. The experimental design was completely randomized with two treatments (T1 = smoked freshwater prawns with herbs; T2 = smoked freshwater prawns without herbs), with 25 experimental units per treatment. After smoking, samples were frozen (-18 C) for proximate composition analysis and portions were sensorially evaluated by 40 tasters based on a simple stimulus method. The smoked freshwater prawns showed medium values of crude protein (44.72%), total lipids (1.39%) and ashes (3.04%) comparatively higher than the values of the in natura freshwater prawns (16.80%, 0.30% and 0.89%, respectively). The aromatic herbs did not affect significantly the proximate composition of smoked freshwater prawns and their use did not interfere on the sensory characteristics evaluated. The smoked freshwater prawns had a good acceptance by the taster.

Revista do Hospital das Clínicas , 2003,
Abstract: This paper reports the study of drug consumption carried out within the population of undergraduate students from 2 colleges of Alfenas, in the state of Minas Gerais state. Both licit and illicit drugs were studied, including alcohol, tobacco, marijuana, cocaine, heroin, crack, inhalants, glue, tranquilizers, stimulants, and others. METHODOLOGY: The research included a wide bibliographical search and the application of a questionnaire to approximately 23% of the students (total of 6500 students). RESULTS: A total of 1500 students participated in this investigation. The results demonstrated that there was a significant consumption of both licit and illicit drugs. The pattern of drug consumption in the research sample was similar to other investigations conducted in Brazil and in other countries. DISCUSSION: It was observed that 55% of the university students use drugs. However, the most surprising finding was that most of the students (88%) answered "yes" to the inquiry, "Have you already tried any type of drug, including alcohol and cigarettes?" The students revealed that they had taken drugs even prior to the admission to the university. The results suggest clearly that the university environment does not necessarily represent the starting point for student drug consumption.

Abstract: infant botulism has been affecting children under one year of age in several regions of the world and honey has been identified as one of the most important source of this food borne disease. despite this, there are scarce data about botulism among children in brazil, specially the type commercial food most implicated in this pathology. this study aimed at investigating the presence of spores of clostridium botulinum in honey commercialized in brazil. one hundred of honey samples commercialized in six different brazilin states (sp, mg, go, ce, mt, sc) were searched for the presence of spores of clostridium botulinum, using thermal shock followed by the inoculation in cooked meat medium (difco?) and incubation in anaerobic conditions. the positives cultures were analyzed by gram stain and seeded in reinforced clostrideo agar (difco?) and sulfito polimixina sulfadiazina -sps (difco?) plates, which were incubated in anaerobic conditions in order to pick up the colonies of this bacteria. the positive colonies were submitted to toxicity test by inoculation in susceptible mice and to biochemical characterization. clostridium botulinum colonies producing actively toxins were detected in 7% of the commercial honey samples, highlighting the relevance of this microorganism for public health due to the high potential risk of honey commercialized in these brazilian regions to cause infant botulism, specially in children under one-year old.

Calpain Dysregulation in Alzheimer’s Disease

Abstract: Alzheimer’s disease (AD) is characterized by the presence of senile plaques and neurofibrillary tangles in the neocortex and hippocampus of AD patients. In addition, a marked decrease in synaptic contacts has been detected in these affected brain areas. Due to its prevalence in the aging population, this disease has been the focus of numerous studies. The data obtained from those studies suggest that the mechanisms leading to the formation of the hallmark lesions of AD might be linked. One of such mechanisms seems to be the dysregulation of calcium homeostasis that results in the abnormal activation of calpains. Calpains are a family of Ca2+-dependent cysteine proteases that play a key role in multiple cell functions including cell development, differentiation and proliferation, axonal guidance, growth cone motility, and cell death, among others. In this paper, we briefly reviewed data on the structure of these proteases and their regulation under normal conditions. We also summarized data underscoring the participation of calpains in the neurodegenerative mechanisms associated with AD. 1. Introduction Alzheimer’s disease (AD) is the most common cause of dementia in the aging population. This disease develops over time and leads to significant cognitive deficits affecting memory, insight, judgment, abstraction, and language functions [1]. AD affects more than 5 million people in the United States and this number is projected to rise to 35 million by 2050 [2, 3]. This estimate underscores both the scope of this health care issue for the society as a whole and the need for the development of therapeutic options for these patients. The diagnosis of this neurodegenerative disease relies on the presence of senile plaques and neurofibrillary tangles in affected brain areas at autopsy. These AD hallmark lesions are the results of the pathological deposition of proteins normally present throughout the brain. Senile plaques are composed of extracellular deposits of beta-amyloid (Aβ) derived by proteolytic cleavage from the amyloid precursor protein (APP) [4–10]. Neurofibrillary tangles, on the other hand, are intracellular bundles of self-assembled tau proteins [11–38]. The formation of both senile plaques and neurofibrillary tangles is associated with progressive and irreversible degeneration of neuronal processes and the loss of synaptic connections [39–50]. Initially, multiple studies focused on defining the characteristics of AD and on the analysis of the composition of senile plaques and neurofibrillary tangles. More recently, data have been obtained on the

Abstract: this work evaluated the acceptance of soups and broths prepared with aromatized meals made from smoked fish carcasses. the species of fish used for smoking were nile tilapia , carp, and pacu. the carcasses were washed, labeled, weighted, immersed in a solution of brine with aromatic herbs, and smoked. the smoked product was crushed to obtain the meal, which was used to cook the soups and the broths . portions of meals, broths and soups were sampled by 40 tasters based on a simple stimulus method, which evaluated characteristics such as aroma, flavor, color, texture, aspect, and general acceptance. considering the three species of fish used to prepare the meals, there were not significant differences (p > 0,05) in the products general acceptance. soups made with these meals had an excellent acceptance , and so no notable differences in the evaluated attributes were found . the broth made with pacu carcass meal was rated the lowest comparing to the other broths. therefore, aromatized meals can be used to supplement products destined to human consumption. they can be also used to supplement school meals improving the nutritional quality of children's meal. such utilization would give a noble destination to residues, which can cause serious impacts if discarded in the environment.

Abstract: this work studied the effect of rosemary on the quality of smoked frog meat (rana catesbeiana) through the analysis of sensory characteristics, centesimal composition, and processing performance. the carcasses were immersed in a solution of brine (20%), in the proportion of 2:1 (volume of brine/weight), soaked in olive oil and smoked at a temperature range from 50 to 90 °c. the experimental delineation was entirely casual with 2 treatments (t1 = frog carcass with rosemary; t2 = frog carcass without rosemary) with 16 repetitions. for the statistical analysis, the saeg 2004 program, with 5% of significance was used. the smoked carcasses presented medium values of rude protein (28,39%), total lipids (5,13%), and ashes (2,79%) comparatively higher than the values of the in natura carcasses (23,41; 2,29, and 0,85%). the rosemary did not affect the centesimal composition. the frog carcasses smoked with rosemary presented better acceptance concerning aroma. the rosemary did not affect the results of the other sensory characteristics. frog meat can be smoked with and without rosemary since it does not interfere in the product acceptance.
