| Seventy-two tyres were placed in four transects (Northern, Southern, Eastern and Western), every 5 km, from the Londrina city limits to the rural areas, to verify the dispersion of Aedes aegypti and Ae. albopictus vectors. Mosquito larvae were collected fortnightly from August 1998 to August 1999. Data were organized according to the average number of larvae collected for each species in each collection site. A total of 62,517 mosquito larvae were collected and distributed into the following species: Aedes albopictus (21.71%); Ae. aegypti (5.54%); Ae. terrens (0.53%); Ae. fluviatilis (0.36%); Anopheles argyritarsi (0.01%); Culex quinquefasciatus (48.37%); Cx. mollis (8.88%); Cx. eduardoi (8.65%); Cx. corniger (0.61%); Cx. bigoti (0.24%); Cx. grupo... |

| We aimed to evaluate the effects of aerobic exercise training (4 days) and metformin exposure on acute glucose intolerance after dexamethasone treatment in rats. Forty-two adult male Wistar rats (8 weeks old) were divided randomly into four groups: sedentary control (SCT), sedentary dexamethasone-treated (SDX), training dexamethasone-treated (DPE), and dexamethasone and metformin treated group (DMT). Glucose tolerance tests and in situ liver perfusion were undertaken on fasting rats to obtain glucose profiles. The DPE group displayed a significant decrease in glucose values compared with the SDX group. Average glucose levels in the DPE group did not differ from those of the DMT group, so we suggest that exercise training corrects dexamethasone-induced... |

| ABSTRACT: A direct search for parasites were used as the diagnostic test to determine the frequency of Leishmania spp. infection in dogs ( Canis lupus familiaris ) under veterinary clinical care in the city of Araguaína, Tocantins, Brazil. For this approach, lymph node cell samples were collected using needle aspiration from 649 dogs of different breeds and ages. Two hundred and sixty four (40.7%) dogs tested positive for amastigote forms of Leishmania spp. Furthermore, 202 (76.5%) dogs that tested positive showed some clinical sign of disease, while 62 (28.4%) dogs were asymptomatic. Dogs <2 years old or those that lived alongside poultry species in peri-domicile areas had a greater chance of infection (P<0.05). Our results revealed the importance... |

| This study evaluated, in vitro, the antimicrobial activity and the anti-adherent property of xylitol (0.5, 2.5 and 5.0%, w/v) on two Pseudomonas aeruginosa strains (ATCC 9027 and clinical). The assay of antimicrobial activity was performed to determine a minimum inhibitory concentration (MIC) and the adhesion test was performed, by which the parameters regarding, growth in the culture medium, number of colony forming units (CFUs) released and slide evaluation by scanning electron microscopy (SEM) were analyzed. The Statistical Package for the Social Sciences (SPSS) was employed for statistical analysis. Results showed that xylitol had no antimicrobial activity on these strains; however, the inhibition of bacterial adherence was observed in microphotographs... |
