Abstract: this study describes the isolation of s. schenckii in hospital and home environments in brazil. samples were collected from surfaces of a veterinary service place and at home. s. schenckii was detected in 1.5% of the samples from the hospital environment. however, this fungus was isolated from all sampled areas in home environments. the isolation of s. schenckii deonstrates that these surfaces could act as infection sources to anials and huans. therefore, employees and pet owners could be exposed to this agent, and the contamination, through surfaces, could occur through the traumatic inoculation of the fungus or by direct contact with pre-existing lesions.

Abstract: percutaneous occlusion of the small patent ductus arteriosus (pda) with gianturco coils is considered the first-line therapeutic option in most centers around the world. however, the use of coils to close ducti larger than 3 mm is associated with higher failure and complication rates. in this paper we report the outcomes of percutaneous occlusion of these larger pdas employing the bioptome assisted anterograde technique mainly using 0.052" coils. from 9/2002 to 8/2006, 14 patients (2 male; median age 8 years and weight 23.6 kg) underwent the procedure. thirteen patients had type a pdas and one had a type c. minimal diameter varied from 3.1 to 5.2 mm (mean = 3.8 ± 0.6 mm). successful implantation was achieved in 13 cases. of these, 2 required additional coils in the same procedure due to significant leaks. five had immediate total occlusion and 8 left the catheterization laboratory with discrete, diffuse, low-velocity residual leaks. there were no complications related to the catheterization procedures. on follow-up, total occlusion was observed in 12 of the 13 patients at echocardiography and none had flow disturbances of the aorta or of the left pulmonary artery. a single patient required a re-occlusion procedure with implantation of an additional coil. percutaneous occlusion of pdas larger than 3 mm using the bioptome assisted anterograde technique mainly with 0.052" coils is feasible, easy to perform, cost effective, safe and efficacious.

Abstract: natural rubber latex was submitted to epoxidation reaction to establish the best reaction conditions without the occurrence of side reactions, which promote coagulation of the latex and development of an agglomerate of rubber. epoxy groups were produced by in situ epoxidation with formic acid and hydrogen peroxide. the samples were characterized qualitatively by fourier transform infrared (ftir) analysis and the degree of modification determined by hydrogen nuclear magnetic resonance spectroscopy (1h-nmr) analysis. a linear increase in the glass transition temperature (tg) was observed. the results show that the epoxidation of natural rubber latex is possible and depends on the reaction conditions.

Abstract: bipolar disorder is a chronic and recurrent disorder, and many factors have been associated with its course and prognosis. dysfunction in social, professional or family life has been correlated with poor outcomes and increased risk of relapse and recurrence, especially when the patient does not adhere to the treatment regimen. within the last decade, new treatments, intended to promote better adherence and minimize the risk of morbidity or hospitalization, have been tested. the multidisciplinary team approach attempts to educate patients and their families about such factors. herein, we evaluate the therapeutic efficacy of this approach in applying the various psychosocial interventions employed in the treatment of bipolar disorder. the objective of this approach is early identification of prodromal symptoms in order to prevent hospitalization and behavioral dysfunction.

Abstract: Poly(ADP-ribose) polymerases are a family of enzymes that catalyze the conversion of NAD+ into ADP-ribose. Among them, Tankyrases have been found to bind to centrosome, mitotic spindle and microsome proteins, in the cytoplasm, and to telomeres in the nucleus, where they play a relevant role in telomere metabolism. However, their precise intracellular localization during interphase has not been so far fully elucidated. We investigated this aspect in situ by double immunofluorescence experiments using antibodies recognizing Tankyrases 1-2 or other proteins residing in specific organelles (Golgi apparatus, mitochondria, lysosomes, endoplasmic reticulum). We used HeLa cells as a model system in vitro, before and after treatment with either actinomycin D or etoposide, to also investigate the possible relocation of Tankyrases during apoptosis. We observed that Tankyrases are distributed both in the nucleus and in the cytoplasm; in this latter compartment, they were found to colocate with the Golgi apparatus but never with the mitochondria; a pool of Tankyrases also colocates with the endoplasmic reticulum and lysosomes. Interestingly, in cells with clear signs of apoptosis, Tankyrases were detectable in the cytoplasmic blebs: this suggests that they are not massively cleaved during apoptosis and persist in the largely heterogeneous apoptotic remnants which are known to contain components of cytoplasmic and nuclear origin.
