AIM: To investigate chromosome 8 numerical aberra- tions, C-MYC oncogene alterations and its expression in gastric cancer and to correlate these findings with histo- pathological characteristics of gastric tumors. METHODS: Specimens were collected surgically from seven patients with gastric adenocarcinomas. Immu- nostaining for C-MYC and dual-color fluorescence in situ hybridization (FISH) for C-MYC gene and chromosome 8 centromere were performed. RESULTS: All the cases showed chromosome 8 aneu- ploidy and C-MYC amplification, in both the diffuse and intestinal histopathological types of Lauren. No significant difference (P < 0.05) was observed between the level ofchromosome 8 ploidy and the site, stage or histological type of the adenocarcinomas. C-MYC high amplification, like homogeneously stained regions (HSRs) and double minutes (DMs), was observed only in the intestinal-type. Structural rearrangement of C-MYC, like translocation, was observed only in the diffuse type. Regarding C-MYC gene, a significant difference (P < 0.05) was observed between the two histological types. The C-MYC protein was expressed in all the studied cases. In the intestinal- type the C-MYC immunoreactivity was localized only in the nucleus and in the diffuse type in the nucleus and cytoplasm. CONCLUSION: Distinct patterns of alterations between intestinal and diffuse types of gastric tumors support the hypothesis that these types follow different genetic path- ways.

HIV/AIDS has brought to light the challenge of incorporating the many influences between living conditions, social characteristics and health services performance to an adequate care for PLWHA （people living with AIDS）. Vulnerability of these populations is under the responsibility of specialized care units whose assistance does not always occur according to their real needs and demands. Therefore, this study aimed to analyze demographic, social and clinical profiles of PLWHA, as well as their follow-up in SS （Specialized Health Services） in Ribeir^o Preto, Brazil. It is a descriptive study conducted by the application of structured questionnaires to 253 patients with HIV/AIDS in follow-up during the years of 2012-2013. Variables were analyzed by descriptive statistics procedures. The findings pointed out gender parity, aging population, low education and economic predominance of class C. Regarding clinical characteristics, there was a predominance of asymptomatic individuals, with no clinical manifestations of AIDS or major comorbidities. The main mode of transmission was through sexual contact. The results led to the need of adequating the assistance provided to the specificities inherent to PLWHA. The care provision should cross an interdisciplinary perspective, targeting recognition of problems and ensuring comprehensive health care adequate to users＇ needs and demands.

Introduction: Due to the growth of the elderly population, there is a notable lack of preparation among family members and society to face the challenges of this new reality, resulting in an increasing demand for homes for the aged (HA). It is necessary to understand how the impairment of physical health, mental health and the level of depression can affect the functional capacity of the institutionalized elderly who live in homes for the aged. Objective: To describe the correlation between depression and functionality of elderly people who live in homes for the aged. Method: A cross-sectional, descriptive study with 70 elderly people of both sexes, aged 60 years or older, who live in HA in the state of Rio de Janeiro. Result: It was verified that the female gender was predominant in the HA consulted. The majority of elderly live in HA voluntarily 48.6% and that 41.43% did not complete elementary school. The majority of the elderly 81.43% had the ability to perform basic activities of daily living and the elderly 52.86% had normal psychological pictures. The worsening of the depressive picture is associated with the worse functioning of elderly who live in HA (p Conclusion: Depression is a factor that is associated with the functional capacity of the institutionalized elderly. The worse the functional level of the institutionalized elderly, the greater the chances of presenting a depressive state.

The aim of this study was to evaluate the effects of silver nitrate in the in vitro development and conservation of passion fruit plants. Experiments were carried out at the Laboratory of Culture and Tissues, in the National Cassava and Fruits Research Center (EMBRAPA), using microcuttings of Passiflora gibertii N. E. Br., previously cultivated in vitro. The microcuttings were placed in MS media supplemented with silver nitrate at concentrations of 0, 1, 2, 4 and 8 mg·L-1, and, during 30, 60 and 90 days, the following variables were identified: Shooting length (cm), number of roots, number and coloration of leaves. A completely randomized design with 30 replications in a split-plot scheme was employed. Polynomial regression equations were adjusted in analysis of variance to compare averages of treatments. The obtained results support the assumption of high sensitivity of passion fruit tissues to ethylene, which reflects in the lost of vigor and in the induction of culture senescence by its accumulation. Based on obtained results, and in order to mitigate this problem, it is possible to indicate an addition of 2 mg·L-1?of silver nitrate in culture media, for the micropropagation of passion fruit plant, allowing the controlling of the atmosphere inside the culture test tubes, during the establishment of explants and other steps of the process.
