2. Study of Coffee Grounds Oil Action in PVC Matrix Exposed to Gamma Radiation: Comparison of Systems in Film and Specimen Forms
The poly (vinyl chloride), PVC, undergoes changes in its physicochemical properties when it is exposed to gamma radiation. Thus, the radiolytic stabilization of PVC is one way for obtain a material with radiation resistance. In this work, we studied the coffee grounds oil as PVC radiolytic protection in two systems forms: PVC film and PVC specimen. The syste

3. Evaluation of radiation protection conditions in intraoral radiology
Abstract Introduction: The dental radiology represents about 20% of human exposure to radiation in radio diagnostic. Although the doses practiced in intraoral dentistry are considered low, they should not be ignored due to the volume of the performed procedures. This study presents the radiation protection conditions for intraoral radiology in Curitiba - PR

4. La educación popular en salud salva: proyecto freireano en tiempos del neoliberalismo
Since the antiquity, the "small rest" of faith in Life that persists, is a protection against the chaos. Local Development is the answer. Paulo Freire said: "My experience along with other experiences, are the basis for hope". Popular Education in health points to making a productive project with identity. Our example comes from Balsa las Perlas, a township

5. Levantamento das condições de biossegurança em radioproteção nos consultórios odontológicos de Campo Grande/MS / Survey on X-ray biosecurity protection condictions at dentistry offices in Campo Grande/MS
O uso dos raios X em Odontologia resulta em um diagnóstico apurado, e muitas vezes, definitivo de estruturas bucais nos tratamentos odontológicos, em função disto diminuir os riscos da infecção cruzada durante exames radiográficos merece tanta consideração quanto controlar os riscos do uso da radiação ionizante e de dar destino adequado aos resíd

6. Leukemia inhibitory factor protects against experimental lethal Escherichia coli septic shock in mice.
Leukemia inhibitory factor (LIF) has recently been associated with septic shock in humans. In this study we sought to determine, in mice, the role of LIF in septic shock. During sublethal endotoxemia, serum LIF levels, as determined by radio-receptor competition assay, peaked at 2 h and were low (3 ng/ml), whereas in lethal Escherichia coli septic shock seru

7. Inhibition of parathyroid hormone secretion and parathyroid hormone-independent diminution of tubular calcium reabsorption by WR-2721, a unique hypocalcemic agent.
Hypocalcemia has been observed in patients receiving WR-2721 [S-,2-(3-aminopropylamino)-, ethylphosphorothioic acid]. WR-2721 is a compound that, after being dephosphorylated, provides protection of normal tissues against radio- and chemotherapy. The hypocalcemic response was accompanied by a decrease in the plasma level of parathyroid hormone (PTH) and by h
