Leishmaniasis, a neglected disease caused by Leishmania protozoans, primarily affects people in tropical and subtropical areas. Chemotherapy based on the use of pentavalent antimonials, amphotericin B, paromomycin, miltefosine and liposomal amphotericin B is currently the only effective treatment. However, adverse effects, long-term treatment and the emergence of parasite resistance have led to the search for alternative treatments. Natural products used in traditional medicine provide an unlimited source of molecules for the identification of new drugs, and the Amazon region has abundant biodiversity that includes several species of plants and animals, providing a rich source of new products and com- pounds. Although the literature describes numerous promising compounds and extracts for combating Leishmania protozoans, the results of such research have not been embraced by the pharmaceutical industry for the development of new drugs. Therefore, this review focused on the antileishmanial activity of extracts, isolated compounds and essential oils commonly used by the local population in the Brazilian Amazonian region to treat several illnesses and described in the literature as promising compounds for combating leishmaniasis.

Applying constant precipitation intensity,which does not occur in natural events,is one of the main limitations concerning rainfall simulators in soil erosion *** present work evaluated the InfiAsper rainfall simulator operating with a new control panel to program rainfalls with different precipitation intensities(PI).Infiltration rates and soil and water losses were evaluated in a Distrophic Acrisol(clay loam texture)with simulated rainfalls of 30 mm and duration of 40 min,considering advanced(AD),intermediate(IN),delayed(DE),and inverted intermediate(II)patterns,all with PI peaks of 110 mm h^(-1),and a constant(CT)*** experimental design was in randomized blocks with five treatments(rainfall patterns)and experimental units measuring 2.5×2.5 *** simulator worked satisfactorily,applying the rainfall according to the preconfigured *** simulated rainfall with the CT and II patterns did not promote runoff nor soil *** and runoff rates varied according to the applied rainfall pattern,reaching 97.8 and 27.3 mm h^(-1)(AD),82.1 and 39.5 mm h^(-1)(IN),and 76.2 and 49.7 mm h^(-1)(DE),*** loss and surface runoff totaled each 4.77 g m^(-2)and 3.9 mm(AD),6.70 g m^(-2)and 6.8 mm(IN),and 6.03 g m^(-2)and 7.0 mm(DE).The InfiAsper simulator modified enables varying precipitation intensity besides obtaining satisfactory results in the field and information consistent with the expected characteristics of natural rainfall *** the intermediate and delayed rainfall patterns,soil and water losses are higher than in the advanced.

AIM To evaluate the accuracy and best cut-off value of fecal calprotectin(FC) and fecal lactoferrin(FL) to predict disease recurrence in asymptomatic patients presenting with anastomotic strictures. METHODS This was a longitudinal single tertiary center study based on prospectively collected data(recorded in a clinical database created for this purpose) performed between March 2010 and November 2014. Crohn's disease(CD) patients with anastomotic stricture who submitted to postoperative endoscopic evaluation were included. Stools were collected on the day before bowel cleaning for FC and FL. Endoscopic balloon dilation(EBD) was performed if the patient presented an anastomotic stricture not traversed by the colonoscope, regardless of patients' symptoms. Successful dilation was defined as passage of the colonoscope through the dilated stricture into the neotermimal *** recurrence was defined as a modified Rutgeerts score of ≥ i2 b. RESULTS In a total of 178 patients who underwent colonoscopy, 58 presented an anastomotic stricture, 86% were asymptomatic, and 48(54% male; median age of 46.5 years) were successfully dilated. Immediate success rate was 92% and no complications were recorded. FC and FL levels correlated significantly with endoscopic recurrence(P < 0.001) with an optimal cut-off value of 90.85 μg/g(sensitivity of 95.5%, specificity of 69.2%, positive predictive value(PPV) of 72.4%, negative predictive value(NPV) of 94.7% and accuracy of 81%] for FC and of 5.6 μg/g(sensitivity of 77.3%, specificity of 69.2%, PPV of 68%, NPV of 78.4% and accuracy of 72.9%) for *** Fecal markers are good predictors of CD endoscopic recurrence in patients with asymptomatic anastomotic stricture. FC and FL may guide the need for EBD in this context.
