Avaliação da influência do enriquecimento ambiental nas variáveis comportamentais de saguis-de-cara-branca (Callithrix geoffroyi) em cativeiro

Six species of the genus Callithrix can be found across the Atlantic Forest extension, being the Callithrix geoffroyi, Geoffroy`s marmoset, the least studied species. The objective of this study is to investigate the behavioral aspects of the species in captivity, and how the environmental enrichment techniques influence those behaviors. To this end, we have studied three specimens of C. geoffroyi, in captivity at Municipal Zoo of Piracicaba, São Paulo. The enclosure includes a 37m2 with under masonry, concrete platforms with external deep, trunks, a floor of grass and soil, e grid in their other three sides. The sampling method was focal per time interval, with records every 30 seconds in sessions of 30 minutes, totaling 30 hours for each animal, which were distributed in a baseline phase, an environmental enrichment phase and post-enrichment phase (n = 3660 records in each phase). The twelve enrichment techniques were applied: the physical environment (branches for perches and hoses fabrics for bedding and vanishing points), cognitive (radio, mirror, puzzle food) and food (insects, flowers and eggs hidden, wrapped). Initially, to determine the period of greatest activity of marmosets, we investigated the pattern of activity for three days (9:00 am to 17:00 pm) consecutively at intervals of 15 minutes, recording the number of active and inactive individuals. The 495 records signaled greater activity in the morning, then selected period for the completion of this work. The ethogram comprised 16 behaviors. The inactivity was the predominant phase behavior baseline and post-enrichment with a significant decrease (h=8,62, p <0.01) in the enrichment phase, and a significant increase in the post enrichment (h=18,15, p <0.001). The same was seen for the use of substrate (grid and ground vs. Trunk and concrete, h=5,09, p <0.001 and h=3,98, p <0.05)... (Complete abstract click electronic access below)

Attraction of the sand fly Nyssomyia neivai (Diptera: Psychodidae) to chemical compounds in a wind tunnel

Background: Similar to other hematophagous insects, male and female sand flies must feed on plants to obtain sugar and, subsequently, energy to complete their life cycles. A large number of compounds emitted by plants may act as volatile signals to these insects. Primary alcohols have been detected in some plants, but in small amounts. In a previous report, the attractiveness of saturated primary alcohols with 7 to 9 carbons was evaluated for Lutzomyia longipalpis, the vector of American visceral leishmaniasis, with positive results.Methods: In the present study, a wide range of primary alcohols, 3 to 10 carbons, were tested to investigate their attractiveness to another sand fly species, Nyssomyia neivai, a putative vector of American cutaneous leishmaniasis. The mixture of compounds that induced the best sand fly response was also evaluated.Results: Of the eight compounds evaluated, hexanol and octanol elicited the best attractive responses for sand fly females.Conclusion: Phytochemicals may be an interesting source of search for new sand fly attractants.

Uso de substâncias ergogênicas suplementares nutricionais em praticantes de musculação

Ergogenic substances are all nutritional or pharmacological additional devices which physiologically influence on the individual's performance. Currently, the practice of physical exercises that modern gyms have is growing and embracing a new recreational space for the population. In particular, for the male audience, weight training; and for the female audience, aerobic gymnastics. This study has the objective of explaining the importance of ergogenic resources in the physiological and psychological planes, emphasizing the point that supplementation is really valid and beneficial. To achieve the objective of the study, a literature review will be carried out, searching for scientific articles published in books, magazines and online newspapers that address some issues that cut across the thematic proposed in this work. From the point of view of Sport Psychology, the issues discussed on body image and emotional changes have concerns professionals of this area, but the literature suggests it is unnecessary the use of ergogenic substances to the concreteness of that purpose. Supplements of any kind will not be enough to transform the psychological and physiological aspects, the way the media assume conclusively. Thus, with our documentary research, we started a provocation that feeds new studies in the area. We conclude that supplementation is a resource that should be used in the final occasion, that is, if the bodybuilders (non-athletes) have time to be nourished from the normal diet, the use of supplements like whey and creatine, are not needed. Used appropriately supplements do not result in physiological damage, however, can contribute beneficially to the individual's nutrition, thus the abusing dosages, in addition to financial loss, can cause damage to the body

Eggplant production in a protected environment with plant vibration

The aim of this study was to evaluate the production of eggplant fruit according to plant vibration in two types of protected environments, with and without an aphid-proof screen, preventing or permitting the entry of pollinators. Two eggplant hybrids (Roxelle, clear purple color and round shape fruits, and Kokushi, purple color and elongated fruits), two vibration treatments (with or without plant vibration), and two environments (with or without screen) were assessed. It was concluded that the presence of insects in the open environment increases marketable fruit yield only in hybrid Roxelle (2120 and 1172 g plant-1, with and without insects, respectivelly), the number of seeds per fruit in both hybrids in treatment without plant vibration (average of 584 and 110 seeds, with and without insects, respectivelly), and that plant vibration may partially replace the absence of pollinator insects in a closed environment protected with a screen, with an increase in fruit yield.

Obtenção de vinagre a partir de mandioca e gengibre

Vinegar is a food product that has a great market potential and beneficial health properties. Each type of vinegar has its taste, since the transformation of alcoholic into acetic acid preserves the raw materials fragrancesand other organic acids can be formed. This study produced and characterized vinegars from ginger and cassava starch. The raw materials were first hydrolyzed by an enzymatic process, thenthey suffered an alcoholic fermentation,and finally an acetic fermentation by the Orleans process. The ash quantity, total acidity in acetic acid, dry extract, and alcohol content of the final product were analyzed based on the current vinegars legislation.The results showed that it is possible to obtain vinegars with good quality from ginger and cassava starch.

Análise do índice de cobertura vegetal da área urbana de Piratininga (SP)

The urban area is now home to 50% of world population and the activities related to their disorganized growth, promote the formation of an unhealthy environment. The urban vegetation is necessary and beneficial, because in addition to bringing the man of nature, mitigates climate change and improve the urban microclimate. This study aimed at surveying and analyzing the rate of existing vegetation in urban Piratininga - SP, and from the data obtained, provide allowance for management and planning of green areas and urban areas. Data came from sample survey conducted in 2007 and computerized survey conducted in 2010 indicated that many new neighborhoods have low opt for planting trees of small to medium which does not enhance the urban environment requiring an environmental planning.

The Pilot Club International was a service oriented club for women, however men are now allowed to join. The South Carolina District was founded in the 1930s for “the promotion of social welfare through the performance of civil and beneficial service of the character generally accomplished by civic organizations, rendering aid and assistance to local Pilot Clubs and implementing at the district level the programs and policies of Pilot Club International.” The Pilot Club International South Carolina District Records consist of a certificate of incorporation, minutes, annual reports, correspondence, resolutions and lists of standing rules.

Evaluation of Attractants for Live-Trapping Nine-Banded Armadillos

In the past 50 years, the range of the nine-banded armadillo (Dasypus novemcinctus) in the south has been rapidly expanding. As their range expands, armadillos increasingly come into conflict with suburban landowners. When foraging, armadillos often uproot ornamental plants. Their rooting also destroys gardens, lawns, and flower beds. Their burrowing can damage tree roots and building foundations. Most armadillo damage is a result of their feeding habits. Armadillos dig shallow holes, 1- 3 inches deep and 3-5 inches long, as they search for soil invertebrates. A recent survey of Georgia county extension agents by scientists at the University of Georgia found that 77.6% of all agents reported receiving complaints or requests for information on armadillos. Armadillo related inquiries made up 10.1 % all inquiries for all agents across the state, surpassing even the white-tail deer (Odocoileus virginianus). Armadillos are often assumed to destroy nests of ground-nesting birds. Armadillo diets have been studied in several states including Alabama, Louisiana, Texas, Georgia, Arkansas, and Florida. According to these studies, vertebrate matter, especially bird eggs, made up an minor portion of their diet. The armadillo’s diet often consists of more than 90% insects, grubs and earthworms. Based on these studies, it seems that claims of armadillos being significant nest predators are unfounded.

Assessing Needs for Computer Pest Management Software in Nebraska Agriculture

A mail survey was conducted to assess current computer hardware use and perceived needs of potential users for software related to crop pest management in Nebraska. Surveys were sent to University of Nebraska-Lincoln agricultural extension agents, agribusiness personnel (including independent crop consultants), and crop producers identified by extension agents as computer users. There were no differences between the groups in several aspects of computer hardware use (percentage computer use, percentage IBM-compatible computer, amount of RAM memory, percentage with hard drive, hard drive size, or monitor graphics capability). Responses were similar among the three groups in several areas that are important to crop pest management (pest identification, pest biology, treatment decision making, control options, and pesticide selection), and a majority of each group expressed the need for additional sources of such information about insects, diseases, and weeds. However, agents mentioned vertebrate pest management information as a need more often than the other two groups. Also, majorities of each group expressed an interest in using computer software, if available, to obtain information in these areas. Appropriate software to address these needs should find an audience among all three groups.

Vitamin E Alters Inflammatory Gene Expression in Alcoholic Chronic Pancreatitis

Objective: To evaluate the effect of vitamin E supplementation on pancreatic gene expression of inflammatory markers in rats with alcoholic chronic pancreatitis. Methods: Wistar rats were divided into 3 groups: control (1), alcoholic chronic pancreatitis without (2) and with (3) vitamin E supplementation. Pancreatitis was induced by a liquid diet containing ethanol, cyclosporin A and cerulein. a-tocopherol content in plasma and liver and pancreas histopathology were analyzed. Gene expression of inflammatory biomarkers was analyzed by the quantitative real-time PCR technique. Results: The animals that received vitamin E supplementation had higher alpha-tocopherol amounts in plasma and liver. The pancreas in Group 1 showed normal histology, whereas in Groups 2 and 3, mild to moderate tissue destruction foci and mononuclear cell infiltration were detected. Real-time PCR analysis showed an increased expression of all genes in Groups 2 and 3 compared to Group 1. Vitamin E supplementation decreased the transcript number of 5 genes (alpha-SMA, COX-2, IL-6, MIP-3 alpha and TNF-alpha) and increased the transcript number of 1 gene (Pap). Conclusion: Vitamin E supplementation had anti-inflammatory and beneficial effects on the pancreatic gene expression of some inflammatory biomarkers in rats with alcoholic chronic pancreatitis, confirming its participation in the inflammatory response mechanisms in the pancreas.

In vitro resistance of articular chondrocytes to 5-Aminolevulinic acid based photodynamic therapy

OBJECTIVE: 5-Aminolevulinic acid based photodynamic therapy (5-ALA-PDT) has revealed promising results in the treatment of inflammatory joint diseases due to the sensitivity of inflamed synovial tissue. For 5-ALA-PDT to be safe and beneficial for intra-articular applications, resistance of chondrocytes is essential to prevent cartilage damage. As no data yet exist, the aim of the present study was to assess in vitro the response of the chondrocytes to 5-ALA-PDT and to compare with osteoblasts and synovial tissue derived cells. METHODS: Bovine articular chondrocytes, osteoblasts, and synovial cells were subjected to 5-ALA-PDT in cell culture. The PpIX accumulation and the function of the cells were assessed for up to 12 days. RESULTS: Bovine chondrocytes showed lower PpIX fluorescence upon incubation with 5-ALA (0.0-2.0 mM) for 4 hours as compared to osteoblasts and synovial cells suggesting a low PpIX accumulation. After incubation with 0.5 mM 5-ALA and application of light at a dose of 20 J/cm2, chondrocytes were functionally not affected (collagen type II and aggrecan mRNA, glycosaminoglycan synthesis) whereas a decrease in the proportion of viable cells was observed in osteoblasts and synovial cells (2+/-2% and 14+/-8%, respectively; chondrocytes 91+/-13%). Chondrocytes showed a 58% reduction of 5-ALA uptake using [3H]5-ALA as compared to osteoblasts and a lower mitochondrial content as assessed by the activity of the mitochondrial marker enzyme citrate synthase (9.2+/- 3.6 mU/mg protein) than osteoblasts (32.6+/-10.5 mU/mg) and synovial cells (60.0+/-10.8 mU/mg). The reduced uptake of 5-ALA and/or the low mitochondrial content, an adaptation to their in vivo environment and the site of PpIX synthesis, presumably explains the lower PpIX content in chondrocytes and their resistance against 5-ALA-PDT. CONCLUSION: 5-ALA-PDT might represent a treatment strategy in inflammatory joint diseases without endangering the cartilage function. However, further in vitro and in vivo experiments are required to confirm this data in the authentic environment of chondrocytes, the articular cartilage.
