CARACTERIZAÇÃO FÍSICA E QUANTIDADE DE NUTRIENTES em FRUTOS DE MARACUJÁ DOCE

O presente trabalho foi conduzido com o objetivo de avaliar algumas características físicas e a distribuição dos nutrientes nos frutos de maracujá doce (Passiflora alata Dryand.), segundo sua classificação. Os frutos classificados como tipo 8 foram maiores e mais pesados que os dos tipos 9 e 12, apresentando maior peso de casca e de polpa. Independentemente da classificação dos frutos, o N, P, B, Cu, Fe e Zn estão distribuídos em maior quantidade na polpa do que na casca dos frutos. O K, Ca, S e o Mn estão distribuídos em maior quantidade na casca do que na polpa dos frutos. O magnésio apresenta uma distribuição na casca levemente superior à da polpa. Na média dos três tipos de frutos, os valores obtidos por fruto (casca+polpa) foram: 578,6 mg de N; 81,9 mg de P; 740,6 mg de K; 56,8 mg de Ca; 64,6 mg de Mg; 98,3 mg de S; 452,3 mg de B; 302,5 mg de Cu; 1471 mg de Fe; 167,5 mg de Mn, e 644,1 mg de Zn.

Detecção de herpesvírus bovino 5 (BoHV-5) em bovinos do Sudeste Brasileiro

This paper reports the detection of bovine herpesvirus type 5 (BoHV-5) by a specific nested PCR assay. Samples were collected from the central nervous system (CNS) of cattle from Minas Gerais and São Paulo States, Brazil. All animals died presenting neurological symptoms. Nineteen frozen CNS samples analyzed had been previously tested by fluorescence antibody test for rabies virus and showed negative results. Three paraffin-embedded brain tissue samples were examined by histopatology and the observed alterations suggested nonsuppurative meningoencephalitis. BoHV-5 was detected in five (22.7%) among 22 tested samples. The occurrence of BoHV-5 infection is reported in the Southeast region of Brazil, indicating that epidemiological studies should be carried out.

Herpes Virus Bovino tipo 1 (BoHV-1) como posible causa de encefalitis en bovinos de la región del Magdalena Medio Colombiano. Estudio serológico y análisis epidemiológico

The bovine Herpesvirus type 1 and type 5 (BoHV-1 and BoHV-5), causing diseases and significant economic losses in farms of worldwide. Both affect the nervous system of cattle, although BoHV-5 has been the most associated with this type of pathogenesis. Given the death of animals with nervous symptoms and negative diagnoses for rabies virus in the area of study, this research focused on the detection of positive reactors to bovine herpes virus serum neutralization. We collected 518 blood samples from animals without Herpesvirus vaccine, in the municipalities of Caparrapi, Cimitarra, Honda and Victoria, in the Middle Magdalena River Region. In addition, epidemiological information useful to discuss neurological disease was collected through primary and secondary sources. For the analysis of data was used chi-square test by identification of relationship between evidence of viral infection and the variables recorded. The results revealed that 286 cases were positive for Herpesvirus infection, corresponding to a prevalence of 55.5%, however, there was no statistical relationship (p < 0.05) between the presence of antibodies and the variables analyzed. In conclusion, some cases of neurological disease in cattle in this region could be due to infection with herpes viruses. We discussed about the presence of BoHV-1 and BoHV-5 in the ambient, diagnosis and monitoring plans, as well as economic losses, which may cause in herds in this area.

Kaposi's sarcoma-associated herpesvirus infection and Kaposi's sarcoma in Brazil

Kaposi's sarcoma (KS) became a critical health issue with the emergence of acquired immunodeficiency syndrome (AIDS) in the 1980s. Four clinical-epidemiological forms of KS have been described: classical KS, endemic KS,iatrogenic KS, and AIDS-associated KS. In 1994, Kaposi's sarcoma-associated herpesvirus (KSHV) or human herpesvirus type 8 was identified by Chang and colleagues, and has been detected worldwide at frequencies ranging from 80 to 100%. The aim of the present study was to evaluate the frequency of KSHV infection in KS lesions from HIV-positive and HIV-negative patients in Brazil, as well as to review the current knowledge about KS transmission and detection. For these purposes, DNA from 51 cases of KS was assessed by PCR: 20 (39.2%) cases of classical KS, 29 (56.9%) of AIDS-associated KS and 2 (3.9%) of iatrogenic KS. Most patients were males (7.5:1, M/F), and mean age was 47.9 years (SD = ± 18.7 years). As expected, HIV-positive KS patients were younger than patients with classical KS. On the other hand, patients with AIDS-associated KS have early lesions (patch and plaque) compared to classical KS patients (predominantly nodular lesions). This is assumed to be the result of the early diagnose of KS in the HIV-positive setting. KSHV infection was detected by PCR in almost all cases (48/51; 94.1%), irrespectively of the clinical-epidemiological form of KS. These results show that KSHV is associated with all forms of KS in Brazilian patients, a fact that supports the role of this virus in KS pathogenesis. © 2006 Brazilian Journal of Medical and Biological Research.

Penile carcinoma: Risk factors and molecular alterations

Penile carcinoma is a rare, male cancer. Although the incidence of penile carcinoma is very low in Western countries, in some countries, the incidence is significantly greater, with penile carcinoma accounting for ≤10% of all male malignancies. Greater insight has been gained in recent years as to its pathogenesis, the risk factors associated with its development, and the clinical and histological precursor lesions related to this disease. In this review, risk and conditions factors for penile carcinoma, molecular alterations in this type of cancer, histological types, and prognostic factors will be discussed in order to further our understanding of the biology and behavior of this cancer. ©2011 with author.
