Violence against Amazon women.

This quantitative and exploratory study analyzed violence against Amazon women presented in print media according to type and severity, and whether aggressors fell under the Maria da Penha law. A total of 181 issues of a regional newspaper were consulted. Based on content analysis, 164 items addressing violence against women were selected and 46 were included in the corpus of analysis.

Frequency of left ventricular diastolic dysfunction by mitral doppler in healthy elderly individuals.

Background: Healthy elderly individuals present alterations in mitral Doppler velocities, which are characteristic of left ventricular (LV) diastolic dysfunction with impaired relaxation.

Objective: To determine the frequency of LV diastolic dysfunction by mitral Doppler in healthy elderly individuals and identify clinical and echocardiographic characteristics associated to this finding.

Methods: Seventy-three apparently healthy individuals (64% women, aged 60 to 80) were carefully selected and submitted to clinical, laboratory and Doppler-echocardiographic assessment, with particular regard to the characteristics of the mitral flow.

Boom-and-bust development patterns across the Amazon deforestation frontier.

The Brazilian Amazon is globally important for biodiversity, climate, and geochemical cycles, but is also among the least developed regions in Brazil. Economic development is often pursued through forest conversion for cattle ranching and agriculture, mediated by logging. However, on the basis of an assessment of 286 municipalities in different stages of deforestation, we found a boom-and-bust pattern in levels of human development across the deforestation frontier.

Pyometra in captive large felids: a review of eleven cases.

Eleven cases of pyometra were diagnosed in a captive exotic felid collection over 3 yr in seven African lions (Panthera leo), two tigers (P. tigris), one liger (lion-tiger crossbreed), and one leopard (P. pardus).

Vascular and metabolic response to statin in the mildly hypertensive hypercholesterolemic elderly.

Introduction: Much evidence indicates the importance of the endothelium and hypercholesterolemia in atherosclerosis, as well as the decline in endothelial function with aging. However, it is unclear if treating dyslipidemia in elderly patients improves endothelial function and reduces C-reactive protein levels.

Objectives: To evaluate vasomotor function, lipids and C-reactive protein in mildly hypertensive and hypercholesterolemic elderly patients treated with atorvastatin.

Matching-to-sample as a model of symbolic behavior for bio-behavioral investigations.

This paper discusses the use of matching-to-sample as a procedure to investigate symbolic behavior acquisition when studying the evolution of language. It is argued that generalized identity and stimulus classes formed after learning arbitrary interconnected conditional stimulus relationships may be the result of basic pre-symbolic processes. Such aspects may thus provide relevant information for interdisciplinary research on symbolic behavior and language evolution.

Hypercalcemia associated with gastric pythiosis in a dog.

A 20-month-old castrated male Labrador Retriever with a 3-month history of anorexia, weight loss, and vomiting was evaluated. Plasma biochemical abnormalities included marked hyperglobulinemia and hypercalcemia. Serum levels of parathyroid hormone, parathyroid hormone-related protein, 25-hydroxyvitamin D, and 1,25-dihydroxyvitamin D were either low or within reference intervals.

Road building, land use and climate change: prospects for environmental governance in the Amazon.

Some coupled land-climate models predict a dieback of Amazon forest during the twenty-first century due to climate change, but human land use in the region has already reduced the forest cover. The causation behind land use is complex, and includes economic, institutional, political and demographic factors. Pre-eminent among these factors is road building, which facilitates human access to natural resources that beget forest fragmentation.

Binding patterns of bovine seminal plasma proteins A1/A2, 30 kDa and osteopontin on ejaculated sperm before and after incubation with isthmic and ampullary oviductal fluid.

Previous studies from our laboratory have reported empirical associations between bovine seminal plasma protein(s) (BSP) A1/A2 and 30 kDa and osteopontin (OPN) in accessory sex gland fluid and bull fertility. These BSP and OPN are believed to bind to sperm at ejaculation and to remain bound until sperm reach the oviduct. The objective of the present study was to evaluate the topographical distribution of BSP A1/A2, 30 kDa and OPN binding on: (1) bovine ejaculated sperm; (2) ejaculated sperm incubated with isthmic oviductal fluid (ODF); (3) ejaculated sperm+isthmic ODF incubated in ampullary ODF.

Detection of Alpha and Gamma-Proteobacteria in Amblyomma triste (Acari: Ixodidae) from Uruguay.

Amblyomma triste is the most prevalent tick species reported in human tick bites in Uruguay and has been found to be infected with Rickettsia parkeri, but no other microorganisms have been reported from this tick. A sample of 254 adults of A. triste was collected by flagging on vegetation in suburban areas in southern Uruguay.

Regional ecosystem structure and function: ecological insights from remote sensing of tropical forests.

Ecological studies in tropical forests have long been plagued by difficulties associated with sampling the crowns of large canopy trees and large inaccessible regions, such as the Amazon basin. Recent advances in remote sensing have overcome some of these obstacles, enabling progress towards tackling difficult ecological problems. Breakthroughs have helped transform the dialog between ecology and remote sensing, generating new regional perspectives on key environmental gradients and species assemblages with ecologically relevant measures such as canopy nutrient and moisture content, crown area, leaf-level drought responses, woody tissue and surface litter abundance, phenological patterns, and land-cover transitions.
