Impact of acute schistosomiasis mansoni and concurrent type 1 diabetes on pancreatic architecture in mice.

It is not well understood how type 1 diabetes (T1D) and concomitant acute schistosomiasis mansoni affect pancreatic architecture. Male Swiss mice were administered streptozotocin (single 100 mg/kg i.p.

Effects of TachoSil and 5-fluorouracil on colonic anastomotic healing.

Background: The administration of intraperitoneal (IP) 5-fluorouracil (5-FU) during the early postoperative period after cytoreductive surgery can decrease local cancer recurrence but may also cause impairment of the anastomotic healing. This study examined the effects of the use of this therapy and of the anastomotic sealing with TachoSil, a fibrin-thrombin coated sealant (FTCS), on the healing of colon anastomoses.

Materials And Methods: Forty male rats were divided into four groups (1-4, 10 rats each) that underwent transection and anastomosis of the left colon.

Screening for decreased glomerular filtration rate and associated risk factors in a cohort of HIV-infected patients in a middle-income country.

With the introduction of combined active antiretroviral therapy and the improved survival of HIV-infected patients, degenerative diseases and drug toxicity have emerged as long-term concerns. We studied the prevalence of decreased glomerular filtration rate (GFR) and associated risk factors in a cohort of HIV-infected patients from a middle-income country. Our cross-sectional study included all adult patients who attended an urban outpatient clinic in 2008.

Interaction of Mycobacterium leprae with human airway epithelial cells: adherence, entry, survival, and identification of potential adhesins by surface proteome analysis.

This study examined the in vitro interaction between Mycobacterium leprae, the causative agent of leprosy, and human alveolar and nasal epithelial cells, demonstrating that M. leprae can enter both cell types and that both are capable of sustaining bacterial survival. Moreover, delivery of M.

Changes in the small intestine of Schistosoma mansoni-infected mice fed a high-fat diet.

The consumption of a high-fat diet modifies both the morphology of the small intestine and experimentally tested effects of schistosomiasis mansoni. However, whether a schistosomiasis infection associated with a high-fat diet causes injury to the small intestine has never been investigated. Mice were fed either a high-fat or a standard-fat diet for 6 months and were then infected with Schistosoma mansoni cercariae.

Histopathological features of keratocystic odontogenic tumor: a descriptive study of 177 cases from a Brazilian population.

The aim of this study was to describe the clinicopathologic features of 177 keratocystic odontogenic tumors (KCOTs) diagnosed in a Brazilian population. A total of 177 KCOTs were reviewed and affected 158 patients with ages ranging from 5 to 79 years (mean age = 32 years) with a slight female predominance. Mandible was the most common affected site (69.

Pseudomonas aeruginosa toxin ExoU induces a PAF-dependent impairment of alveolar fibrin turnover secondary to enhanced activation of coagulation and increased expression of plasminogen activator inhibitor-1 in the course of mice pneumosepsis.

Background: ExoU, a Pseudomonas aeruginosa cytotoxin with phospholipase A2 activity, was shown to induce vascular hyperpermeability and thrombus formation in a murine model of pneumosepsis. In this study, we investigated the toxin ability to induce alterations in pulmonary fibrinolysis and the contribution of the platelet activating factor (PAF) in the ExoU-induced overexpression of plasminogen activator inhibitor-1 (PAI-1).

Methods: Mice were intratracheally instilled with the ExoU producing PA103 P.

Is higher prevalence of cervical intraepithelial neoplasia in women with lupus due to immunosuppression?

Background: Cervical cancer (CC) is still the second in prevalence and mortality among women. In spite of previously observed higher incidence of cervical dysplasia among systemic lupus erythematosus (SLE) patients, few studies have considered the influence of classic risk factors and the use of immunosuppressors (IM).

Objectives: To study cervical dysplasia prevalence among SLE patients submitted or not to immunosuppression and to evaluate its association with classic risk factors.

ExoU-induced vascular hyperpermeability and platelet activation in the course of experimental Pseudomonas aeruginosa pneumosepsis.

To address the question whether ExoU, a Pseudomonas aeruginosa cytotoxin with phospholipase A2 activity, can induce hemostatic abnormalities during the course of pneumosepsis, mice were instilled i.t. with the ExoU-producing PA103 P.
