2. Analysis of macrophage subtypes and annexin A1 expression in lesions of patients with cutaneous leishmaniasis
Abstract INTRODUCTION: Cutaneous leishmaniasis is caused by protozoa of the genus Leishmania and transmission occurs through the bite of sandflies. It is an infectious disease, which affects skin and mucosa. The aim was to quantify the macrophages M1 and M2 and the annexin A1 expression in the skin lesions of patients with cutaneous leishmaniasis. METHODS

3. IDENTIFICATION OF CANINE VISCERAL LEISHMANIASIS IN A PREVIOUSLY UNAFFECTED AREA BY CONVENTIONAL DIAGNOSTIC TECHNIQUES AND CELL-BLOCK FIXATION
After the report of a second case of canine visceral leishmaniasis (CVL) in São Bento da Lagoa, Itaipuaçu, in the municipality of Maricá, Rio de Janeiro State, an epidemiological survey was carried out, through active search, totaling 145 dogs. Indirect immunofluorescence assay (IFA), enzyme-linked immunosorbent assay (ELISA), and rapid chromatographic im

4. Immunofluorescence testing in the diagnosis of autoimmune blistering diseases: overview of 10-year experience
BACKGROUND: Immunofluorescence testing is an important tool for diagnosing blistering diseases. OBJECTIVE: To characterize the immunofluorescence findings in patients diagnosed with autoimmune blistering skin diseases. METHODS: We retrospectively analyzed immunofluorescence results encompassing a 10-year period. RESULTS: 421 patients were included and divid

5. Detection of respiratory viruses by real-time polymerase chain reaction in outpatients with acute respiratory infection
Viruses are the major contributors to the morbidity and mortality of upper and lower acute respiratory infections (ARIs) for all age groups. The aim of this study was to determine the frequencies for a large range of respiratory viruses using a sensitive molecular detection technique in specimens from outpatients of all ages with ARIs. Nasopharyngeal aspirat

6. Immobilization and therapeutic passive stretching generate thickening and increase the expression of laminin and dystrophin in skeletal muscle
Extracellular matrix and costamere proteins transmit the concentric, isometric, and eccentric forces produced by active muscle contraction. The expression of these proteins after application of passive tension stimuli to muscle remains unknown. This study investigated the expression of laminin and dystrophin in the soleus muscle of rats immobilized with the

7. Atividade gelatinolítica in situ e imuno-expressão das metaloproteinases 2 e 9 em lesões potencialmente malignas e carcinomas espinocelulares bucais / In situ gelatinolytic activity and immunoexpression of metalloproteinases 2 and 9 in oral potentially malignant lesions and squamous cell carcinomas
The transition from normal oral mucosa to invasive carcinoma has a complex and multifactorial etiology. Oral leukoplakia (OL) is regarded as the most prevalent potentially malignant oral lesion, with a higher tendency for malignant transformation if compared to normal oral mucosa. Although an increased activity of matrix metalloproteinases (MMPs) 2 and 9 in

8. The influence of selected pathological states on the somatostatin-like immunoreactive (SOM-LI) endocrine cells in the mucosal layer of the porcine descending colon
This study reports on changes in the number of somatostatin-like immunoreactive (SOM-LI) endocrine cells in the porcine descending colon, caused by chemically driven inflammation, axotomy and proliferative enteropathy (PE). The distribution pattern of SOM-LI endocrine cells has been studied using the routine single-labelling immunofluorescence technique. Sem

9. A ten-year follow-up of human leptospirosis in Uruguay: an unresolved health problem
Leptospira spp. are delicate bacteria that cannot be studied by usual microbiological methods. They cause leptospirosis, a zoonotic disease transmitted to humans through infected urine of wild or domestic animals. We studied the incidence of this disease in the Uruguayan population, its epidemiologic and clinical features, and compared diagnostic techniques.

10. Molecular basis for the diagnosis and treatment of acute promyelocytic leukemia
Acute promyelocytic leukemia is characterized by gene rearrangements that always involve the retinoic acid receptor alpha on chromosome 15. In the majority of patients t(15;17) is detected, which generates the promyelocytic leukemia gene/retinoic acid receptor alpha rearrangement. This rearrangement interacts with several proteins, including the native promy

11. Raiva em equino no município de Porto Alegre - RS, Brasil = Equine rabies in the city of Porto Alegre - RS, Brazil / Equine rabies in the city of Porto Alegre - RS, Brazil
Background: rabies is a fatal zoonosis caused by a highly neurotropic RNA virus which causes neurological signs and that is distributed almost worldwide. Rabies affects domestic and wild animals and this is a disease transmitted by their bites, through which the virus present in the saliva is inoculated. In Brazil, Desmodus rotundus is the main hematophagous

12. Comparison of a rapid cytomegalovirus pp65 antigenemia assay revealed by immunofluorescence to an in-house assay revealed by immunoperoxidase for diagnosis in solid organ transplant recipient patients
Cytomegalovirus (CMV) antigenemia is still one of the two major assays available for diagnosis and monitoring of CMV infections. A commercial rapid test recently available in Brazil for quantification of human cytomegalovirus pp65 antigenemia revealed by immunofluorescence technique was compared with the original in-house method revealed by immunoperoxidase
