Asymptomatic mixed breed dogs (49) from a region of high incidence of visceral leishmaniosis in Portugal were examined for the presence of Leishmania-specific cellular immunity using a proliferation assay and humoral immunity using an indirect antibody fluorescent test (IFAT) and an ELISA. The results were compared directly with 25 mixed breed dogs(More)
The leishmanin skin test was used to detect Leishmania-specific cellular immunity in asymptomatic dogs from an endemic region of visceral leishmaniosis. The test was safe since no clinical signs of intolerance to leishmanin were detected during 1 month, in 14 dogs after inoculations of 3 x 10(8) promastigotes/ml. In another group of four dogs no cross(More)
Due to the increased availability of low cost network technology, the use of networks to interconnect sensors, actuators and controllers is now widely accepted. Such increased availability is one of the driving factors for the implementation of smart sensor networks. To ensure the correctness of the supported applications, the communication network must(More)
Asymptomatic dogs from a Kala-Azar endemic region were screened for infection status by parasitological, immunological and molecular techniques. Bone marrow was examined for the presence of parasites by NNN culture and by using the Lmet 2 DNA probe. All the samples were negative in culture but 24 of 41 were positive as determined by the probe. Cellular and(More)
PURPOSE To report an uncommon case of a 29-year-old Caucasian male diagnosed with unilateral choroidal neovascularization (CNV) secondary to punctate inner choroidopathy leading to visual impairment. METHODS This is a retrospective and descriptive case report based on data from clinical records, patient observation and analysis of ancillary diagnostic(More)
Counting the number of Collembola in digital images is a routine task in laboratories of soil ecotoxicology. This process is based on a direct visual identification of Collembola, and is consequently a time consuming task. This paper present a fully automatic system for counting the number of Collembola in digital images. The system selects the interest(More)
PURPOSE To compare cardiac muscle cells width and cardiomyocyte lipofuscin pigment presence between malnourished and non-malnourished necropsied adults. METHODS Out of 315 necropsy protocols of adults randomly chosen, those with edema, ascitis, systemic arterial hypertension, chronic liver disease, and heart disease were excluded. Malnutrition was defined(More)
In epilepsy persistence of seizures, despite appropriate pharmacological therapy, motivates referral to surgery of epilepsy, currently the most effective treatment. Because surgery is not indicated for all patients, search for alternative therapies is ongoing. Preliminary data suggests the potential benefit of sensory-motor rhythm modulation on the(More)
This paper presents guidelines for the accurate evaluation of harmonics and flicker generated by ac electric arc furnaces, and its propagation through transmission and distribution systems. It is presented a typical case where a HV system supplies a high capacity arc furnace. The electrical network is simulated using the ATP version of the EMTP where a(More)
