Convivendo com o lixo: a vulnerabilidade socioambiental no bairro Jardim Graminha, Leme, Sao Paulo

Urban space occupation occurs in an extremely disordered way. Political, economical and social aspects converge to create a problem that affects mostly poor people who are impelled to occupy areas where social and environmental problems are likely to emerge. Floods, landslides and different forms of pollution have more effects on the most vulnerable groups. In many cases, actions taken by the government legitimate this structure and reinforce its reproduction. This work seeks to confirm both that poor people are vulnerable to social and environmental problems resulting from inappropriate urban solid waste disposal and that the local government contributes to this situation. It is assumed that the issue is related first to the government’s disregard for poor people who live in unhealthy places and, second, to the inability of such people to demand for better living conditions. In this study, a waste disposal area within Jardim Graminha neighborhood in Leme (São Paulo) was selected to be analyzed by means of systematic observation. The study clearly shows that poor people living near that area where different types of garbage are disposed are vulnerable and the government does not control the situation. It is also pointed out that governmental intervention and the use of political and technical tools are necessary for planning and managing the area to mitigate these problems and to decrease poor people’s social and environmental vulnerability.

Redução do medo durante o tratamento odontológico utilizando pontas ultrassônicas

Over the last few years, new technologies have been developed to making cavity preparations, among which the diamond burs CVDentus® (CVDentus, São José dos Campos, Brazil) are outstanding. These points are produced by chemical deposition from the vapor phase, forming a single diamond stone, with greater durability than the conventional diamond burs. Coupled to the ultrasound appliance, they have several clinical applications in Dentistry with advantages over conventional rotary instruments, such as lower pressure, noise, vibration and heat, as well as reducing the need to use local anesthesia, contributing to minimize patient’s fear and anxiety. The aim of this study was to present the complete restorative dental treatment performed with this system in a child patient with a prior history of non-cooperative behavior. The use of this new technology offered the patient greater comfort, making it possible recondition the patient’s attitude to dental treatment, in addition to favoring conservative cavity preparations to be made.

Estocagem tecidual e utilização de lipídeos em Matrinxã, Brycon cephalus (Günther, 1869)

Lipids have important biological functions, suchas membrane constituents, hormone precursors, and are efficient energy reserves, due to thers high caloric content. In fish, but not in mammals, lipid storage patterns are quite diverse. The aim of this study was to determine lipid distribution in somatic and reproductive tissues of matrinxã, Brycon cephalus, both male and female, highlighting somatic indices related to lipid dynamics. From Oct 98 to Jan 99, a total of 174 fish (8-12 each month) were sampled. After fish anesthesia, heparinized blood was collected for plasma triacylglycerol determination. Fish were individually weighed and measured, and liver, gonads and visceral fat were collected and weighed for HSI (hepatosomatic index), GSI (gonad somatic index) and MFI (mesenteric fat index) calculation. The highest values of total lipids were found in red muscle (about 18%), liver and gonads (about 16.5%). The white muscle had a lower concentration (2.5%). Analyses of variance of HSI and MFI showed fluctuations along the experimental period with lowest concentrations in the periods of highest temperatures. Matrinxã store lipids in several body tissues, including mesenteric fat, liver, muscles and gonads.
