Abstract: objective: to compare the generation of continuous positive airway pressure using a hand-made device (underwater seal) or a ventilator (inter 3?). methodology: two positive airway pressure generation systems were compared through laboratory simulations. measurements were not considered if the mechanical ventilator required calibration or in the presence of gas flow variation (flowmeter sphere oscillation). recordings were assessed in terms of the capacity to produce the desired pressure (3, 5 and 6 cmh2o) when submitted to three different flow values (8, 10 and 12 l/min). for that end, student's t test for paired samples and the nonparametric man-whitney test for independent samples were employed. results: we verified that the systems behave in different manners under the same conditions of flow and positive end expiratory pressure. for the mechanical ventilator, the mean pressure behavior under continuous positive airway pressure at 3 cmh2o with flows of 8, 10 and 12 l/min were 2.26±0.41, 2.22±0.37, 2.04±0.41, respectively; under positive end-expiratory pressure at 5 cmh2o we found 3.96±0.41, 3.87±0.43 and 3.75±0.52; and under positive end-expiratory pressure at 6 cmh2o the values recorded were 4.94±0.40, 4.85±0.41 and 4.72±0.37. for the underwater seal, the mean pressure behavior under continuous positive airway pressure at 3 cmh2o with flows of 8, 10 and 12 l/min were 4.24±0.24, 4.46±0.26, 4.72±0.37, respectively; at 5 cmh2o the values were 5.97±0.17, 6.28±0.18, 6.47±0.31; and at 6 cmh2o we recorded 6.85±0.20, 7.17±0.29 and 7.53±0.31. all the comparisons were statistically significant (p = 0.000). conclusion: through our recordings it was possible to observe that the inter 3? continuous positive airway pressure system was more stable than the underwater seal.

Abstract: this work deals with the biodegradation of blends of poly(b-hydroxybutyrate)/starch and poly(b-hydroxybutyrate-co-hydroxyvalerate)/starch. the blends were obtained by evaporation of the solvent in the mixture of the polymers in chloroform. tests were carried out in presence of micro-organisms which acted as biodegradation agents. the blends were consumed as carbon substrate and the production of co2 was evaluated in the process. in addition, the polyesters' mechanical properties were reduced by the incorporation of starch in its structure. (1h) nmr and infrared spectroscopy detected some characteristic polyester degradation groups in the polyesters' chemical structure, thus confirming the alteration suffered by it.

Abstract: Aim. To evaluate the effect of cigarette smoke on water sorption and solubility of four adhesive systems. Materials and Methods. Sixteen disks of each adhesive system were prepared (Adper Scotchbond Multipurpose Adhesive (SA); Adper Scotchbond Multipurpose Adhesive System (Adhesive + Primer) (SAP); Adper Single Bond Plus (SB); Adper Easy One (EO)). Specimens were desiccated until a constant mass was obtained and divided into two groups . One-half of the specimens were immersed in deionized water, while the other half were also immersed, but with daily exposure to tobacco smoke. After 21 days, disks were measured again and stored in desiccators until constant mass was achieved. Data were calculated according to ISO specifications and statistically analyzed. Results. The tobacco smoke only significantly affected the water sorption and solubility of EO. There were significant differences in both analyses among materials tested. The SB exhibited the highest water sorption, followed by EO, which demonstrated significantly higher solubility values than SB. The SA and SAP showed low water sorption and solubility, and there were no significant differences between the two. Conclusion. Regardless of smoke exposure, both simplified adhesive systems presented an inferior performance that could be related to the complex mixture of components in such versions. 1. Introduction Many studies have shown that cigarette smoking is associated with deleterious health effects such as heart disease [1], chronic obstructive pulmonary disease, cancer [2], fertility problems [3], and periodontal disease [4]. In cosmetic restorative dentistry, some of the substances coming from tobacco can be absorbed by resin composite, dentin, and enamel surface [5] and lead to tooth/composite discoloration [6–10]. Moreover, bond strength reduction has been described due to the fact that cigarette particles may prevent effective contact between dentin and resin composite [11]. The mainstream smoke emitted from the mouth end is complex and composed by many physical and chemical processes [12]. In general, smoke formation is mostly produced by combustion and pyrolysis reactions and can be classified in two distinct phases. The first is called the vapour phase, consisting mainly of nitrogen, oxygen, carbon monoxide, carbon dioxide, acetaldehyde, methane, hydrogen cyanide, nitric acid, and acetone. The second category is the particulate phase. It consists of nicotine, water, and tobacco-specific nitrosamines ranging from 0.1 to 1.0?μm in diameter [12–17]. Beside many research reports on the staining

Abstract: The diagnosis of liver cirrhosis in patients with chronic hepatitis C has not always been easy, since the gold standard method is the liver biopsy, which is an invasive procedure with interobserver accuracy problems and there have been reports of complications including records of deaths due to hemoperitoneum. Cirrhosis changes the prognosis of the subject with hepatitis C and requires a different clinical management. This study aimed to identify clinical and laboratory variables associated with the diagnosis of cirrhosis in the ultrasonography of patients infected with hepatitis C. In a case-control study, we evaluated 70 cirrhotic patients with chronic hepatitis C compared to a control group of 70 non-cirrhotic people with positive HCV. The results showed, through logistic regression analysis, that the variables blood donor and professional athlete, adjusted for alcohol consumption, showed OR 0.24 and 0.18, with p values of 0.044 and 0.035, respectively. We conclude that the diagnosis of cirrhosis in patients with chronic hepatitis C remains challenging, but the patients with the condition of blood donor or professional athlete prove to be less likely to cirrhosis in ultrasonography in the initial consultation.
