Spatiotemporal analysis of mosquito-borne infections and mosquito vectors in mainland Portugal.

Background: The incidence of mosquito-borne infections has increased worldwide. Mainland Portugal's characteristics might favour the (re)emergence of mosquito-borne diseases. This study aimed to characterize the spatial distribution of vectors and notification rates of imported cases of mosquito-borne infections in mainland Portugal and demarcate the areas where these geographies overlap.

Resection of Bone Tumor Guided by Gamma Probe and Evaluation of Postoperative Pain.

Osteoid osteoma is a benign neoplasm commonly found in young men, but that can be found in every age, which affects mainly long bones, clinically characterized by continuous and limiting pain that is relieved by salicylates. It is a small lesion composed of immature osteoid tissue, central hypervascularization and surrounding sclerotic area. Its diagnosis is performed by the clinic and aided by imaging tests, such as common radiography and computed tomography.

Aneurysmal Patellar Bone Cyst: Case Reportt.

Patellar tumors are rare. Commonly benign, giant-cell tumors and chondroblastomas are the most frequent types of this tumor. Aneurysmal bone cysts are a less common type, corresponding to less than 1% of the cases.

The effect of soil on cork quality.

The present work aimed to contribute for a better knowledge regarding soil features as cork quality indicators for stoppers. Cork sampling was made in eight Cork oak stands (montados de sobreiro) located in the Plio-Plistocene sedimentary formations of Península de Setúbal in southern Tagus River region. The samples used to classify the cork as stopper for wine bottles were obtained in eight cork oak stands, covering soils of different types of sandstones of the Plio-plistocene.

Susceptibility of the horn fly, Haematobia irritans irritans (Diptera: Muscidae), to insecticides in Brazil.

Since horn fly populations became established throughout Brazil, complaints regarding control failure have increased around the country. A broad survey to evaluate the susceptibility of horn flies to both organophosphate (OP) and pyrethroid insecticides was conducted from October 2000 to April 2003. Bioassays using filter papers impregnated with cypermethrin, permethrin or diazinon were conducted on 154 horn fly populations in 14 states and 78 municipalities.

Osteosarcoma with atypical location in an elderly female patient.

Osteosarcoma most frequently affects long bones, particularly around the knee, and is therefore rare in the forearm. We report the case of a 67-year-old woman presenting with progressive lesion of the distal radius. A pathological diagnosis of osteoblastic osteosarcoma was suspected and was confirmed by needle biopsy.

Insecticide susceptibility of horn flies, Haematobia irritans (Diptera: Muscidae), in the State of Mato Grosso do Sul, Brazil.

Horn fly susceptibility to insecticides was evaluated in the state of Mato Grosso do Sul, Brazil, from October 2000 to September 2002. Insecticide bioassays (n=57) were conducted in 38 ranches from 14 municipalities throughout the state. Horn flies from wild populations were collected on cattle and exposed to filter papers impregnated with cypermethrin, permethrin, or diazinon and mortality was assessed after two hours.

Susceptibility to diazinon in populations of the horn fly, Haematobia irritans (Diptera: Muscidae), in Central Brazil.

From October 2000 to April 2001, insecticide bioassays were conducted in 18 ranches from 10 counties in the states of Mato Grosso and Mato Grosso do Sul, in Central Brazil. Horn flies from wild populations were exposed to diazinon-impregnated filter papers immediately after collection on cattle, and mortality was recorded after 2 h. A high susceptibility to diazinon was observed in all tested populations.

BmTI antigens induce a bovine protective immune response against Boophilus microplus tick.

Boophilus microplus trypsin inhibitors (BmTIs) present in larvae were preliminarily characterized as active proteins, approximately 10-18 kDa, by SDS-PAGE. BmTIs showed trypsin inhibitory activity on reverse zymography containing gelatin (0.03%) and also inhibited others serine proteinases (human neutrophil elastase and human plasma kallikrein).
