Motivos da recusa à doação de órgãos apontados familiares de pessoas com morte encefálica

Purpose: Study aiming to understand the reasons for the refusal to donate organs by relatives of potential donors living in the Mid-Western region of the São Paulo state. Method: Qualitative study performed after data collection by the Organ Procurement Organization (OPO) Division of a reference hospital in the region. Relatives were contacted to participate in a semi-structured interview, and after the subjects in the study were characterized, four guiding questions were presented; their respective answers were recorded to be transcribed later. The Analysis of Content method proposed by Bardin was used to organize the speeches. Results: From 2006 to 2008, 30 (35.3%) families contacted by OPO have refused to agree with the organ donation. From that universe, 16 family members were interviewed. Data was systematized in three major themes: The experience of being informed on a family member’s brain death, decision concerning to the organ donation and aspects that would facilitate the decision to agree with the organ donation. Conclusion: the identification of reasons for the refusal and the suggestions presented has provided subsidies to improve the organ donation for transplantation process.

Germinação de sementes de maracujazeiros: água, luz, temperatura e reguladores vegetais

The production of seedlings of passion fruit is done mainly with the use of seeds by most producers. It can also be propagated by cuttings, layering and in vitro tissue culture. However, even when grafting is used, it is necessary to use seeds to produce the rootstock. Nevertheless, most Passifloracea species have germination problems, making it difficult to obtain seedlings. Although several studies have been developed in an attempt to increase seed germination of passion fruit there are still difficulties in understanding the germination process and also disagreement about seed dormancy. Thus, the present study aimed to review papers related to seed germination of passion fruit emphasizing aspects such as mechanical resistance to water ingress, the need for adequate light and temperature and the use of plant growth regulators in overcoming seed dormancy. It was noticed that, in general, the passion fruit seeds are photoblastic negative and exhibit physiological dormancy, being no need of seed scarification to stimulate its germination.

Comparação de medidas obtidas por diferentes aplicativos computacionais na obtenção de áreas citrícolas do Município de Botucatu

The great importance of citrus in São Paulo state, particularly in Botucatu city, the and its major expansion in area in recent years and the advancement of techniques for environmental monitoring, such as remote sensing motivated the present research. The aim of this study was the determination the areas and perimeters of citrus in the Botucatu city, São Paulo state, Brazil, obtained through the softwares: Carta Linx, GIS-Idrisi and SPLAN, using aerial colored photographs of 2005, scaled at 1:30000 with longitudinal covering of approximately 60% and 30% laterally. The areas obtained from the aerial photographs and evaluated by Carta Linx presented values closer to the terrestrial reality in determining areas and perimeters, whereas GIS-Idrisi showed discrepancies in the determination of the perimeters, due to working with matrixes. SPLAN and Carta Linx had values for perimeters and areas in close proximity, due to work with vectors.

Técnicas para obtenção e tratamento de macrofotografias de insetos

Workings related insects macro-photographs production are little widespread in the scientific community. However, the use of images has wide application, serving for scientific publications, conferences, courses, databases and development of illustrated identification keys. Thus, methodologies were developed to assist in capturing and processing highresolution images, improving its quality, without, however, their technical characteristics.

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.

Avaliação do processo de hidrólise enzimática para obtenção de açúcares a partir de gengibre (Zingiber officinale)

Ginger is a starchy tubers prized for their chemical components. In the production of any kinds of beverages has been added to the extract of ginger. However, in view of the high starch content, a possibility of further development of the agribusiness sector this would be the hydrolysis tuberous rhizomes disqualified for export in order to obtain hydrolysates that would be used in the preparation of fermented beverages. This work aimed to evaluate the production of sugar from rhizomes of ginger. Two α-amylase enzymes were tested in the stage of liquefaction (Liquozyme Supra (T1) and Termamyl 2X (T2)), as well as the effect of time of action of amyloglucosidase (AMG 300L). The hydrolysates were analyzed in liquid chromatography (HPLC) and was also carried out the mass balance of the processes. The results showed higher hydrolysis of starch in the treatment that used Liquozyme Supra in liquefaction. The action time of 18 hours of AMG 300L hydrolyzate which gave an 98% of its chemical components was glucose.

Atuação do interferon-tau no reconhecimento materno da gestação

Maternal recognition of pregnancy is a process by which the conceptus signals its presence to the mother in order to prolong the life of the corpus luteum (CL) thus maintaining the pregnancy. This process occurs between days 15 and 19 after fertilization and is the most important biological challenge for obtaining satisfactory reproductive indices in bovine. Interferon-tau (IFN-τ) glycoprotein -secreted in the uterus by the conceptus- has a paracrine action inhibiting the expression of estrogen receptors (ESR1) and oxytocin (OXTR) in the endometrium, thus preventing the release of luteolytic pulses of prostaglandin F2 alpha (PGF2α), hormone responsible for the onset of luteolysis. IFN-τ also increases the expression of several interferon-stimulated genes (ISGs) in the uterus, CL, and blood cells. Direct endocrine action of IFN-τ on extrauterine tissues stimulates ISGs expression, which in the corpus luteum seems to be involved with luteal resistance to luteolytic action of PGF2α. This review discusses recent findings on the luteolysis mechanism in the bovine and endocrine and paracrine mechanisms such as IFN-τ during the maternal recognition of pregnancy.
