Endovascular Treatment of Spontaneous Isolated Common and External Iliac Artery Dissections with Preservation of Pelvic Blood Flow

Spontaneous isolated dissection of iliac arteries is very rare, with few reports in the literature. Medical, surgical, and endovascular treatment modalities have all been used to manage iliac artery dissections. We report a case of symptomatic, isolated, spontaneous dissection of the common iliac and external iliac arteries. Both dissections were successfully treated by separate percutaneous stent-graft placement, preserving hypogastric artery flow. This technique is interesting because it provides adequate sealing of proximal and distal dissection sites while preserving hypogastric artery and pelvic flow.

Viability of Lactobacillus acidophilus La-5 in the presence of Williopsis saturnus var. suaveolens

Maintaining the viability of probiotic microorganisms from production to consumption has long been a technological challenge for the food industry. The objectives of this study were to evaluate the in vitro interaction between Lactobacillus acidophilus La-5 and Williopsis saturnus var. suaveolens and the effect of this yeast on acidification kinetics, viability of Lactobacillus acidophilus and post-acidification in fermented milk during refrigerated storage at 5 °C. The in vitro study showed a positive interaction between the acid cell free-supernatant (CFS) of probiotic bacteria La-5 and the yeast. The addition of W. saturnus var. suaveolens increased the fermentation time due to consumption of the organic acids produced by L. acidophilus. During the refrigerated storage of the samples, the presence of the yeast increased the viability of L. acidophilus and reduced post-acidification. However, the mechanism of such interaction of bacteria and yeast is not fully understood.

Presence of Cytoplasmic Organelle chromatoid body in class Insecta

In the present work we made a review on the cytoplasmic organelle chromatoid body (CB) in the Insecta class. We note that the CB has been described in 14 orders of insects. However, we emphasize the importance of new orders should be analyzed, since the detailed knowledge of the reproductive biology of insects may help in understanding taxonomic, evolutionary and mainly contribute to the development of tools that minimize the populations of vectors and insect pests, contributing directly to human welfare.

Identification of the presence of the mutation of the gene of PKD not associated of HCM in Persian cats - case report

Polycystic kidney disease (PKD) is a hereditary autosomal dominant disorder that mainly affects Persian cats; it is an important cause of chronic kidney disease in this species. Hypertrophic cardiomyopathy (HCM) is the most common heart disease in cats, and there is evidence of a genetic origin in some breeds. Although neither of these disorders is rare in cats, according to our literature review, this is the first report of the concomitant occurrence of PKD and HCM in Persian cats in Brazil.

Evaluation of the presence of microorganisms in solid-organ preservation solution

OBJECTIVE: To assess the presence of microorganism contamination in the preservation solution for transplant organs (kidney/pancreas). Method: Between August 2007 and March 2008, 136 samples of preservation solution were studied prior to graft implantation. Variables related to the donor and to the presence of microorganisms in the preservation solution of organs were evaluated, after which the contamination was evaluated in relation to the recipient culture variable. Univariate and multivariate statistical analyses were performed. RESULTS: The contamination rate of the preservation solution was 27.9%. Coagulase-negative Staphylococcus was the most frequently isolated microorganism. However, highly virulent agents, such as fungi and enterobacteria, were also isolated. In univariate analysis, the variable donor antibiotic use was significantly associated to the contamination of the preservation solution. on the other hand, multivariate analysis found statistical significance in donor antibiotic use and donor's infectious complications variables. CONCLUSIONS: In this study, 27.9% of the preservation solutions of transplant organs were contaminated. Infectious diseases and non-use of antibiotics by the donor were significantly related to the presence of microorganisms in organ preservation solutions. Contamination in organ preservation solutions was not associated with infection in the recipient.
