SUICÍDIO EM IDOSOS: UMA REVISÃO SISTEMÁTICA

O suicídio em idosos é um assunto pouco abordado, porém de muita importância já que o número de idosos no Brasil vem aumentado cada vez mais. Logo, este trabalho é uma revisão sistemática que contempla os maiores fatores de risco sobre o suicídio em idosos. Para a confecção do trabalho foram selecionados três bancos de dados: Scielo, BDTD e Portal Capes. Foram selecionados 21 estudos, todos em língua portuguesa, publicados no Brasil nos últimos 7 anos. Dentre os principais fatores de risco associados ao suicídio em idosos, destacam-se: depressão, perda do sentido de vida, sentimento de inutilidade e doenças físicas

Impact of the use of nano-fertilizers in soybean crop

PosterIn the Cerrado region, Rio Verde GO, Brazil, rural producers seek to increase the soybean productivity efficiently. The objective of this work was to develop a complementary fertilization protocol to the traditional management of the producer (TMP) of Rio Verde-GO applying nano-fertilizer (MIST-P and MIST TPS) during the sowing of the soybean crop.Instituto de Fisiología y Recursos Genéticos VegetalesFil: Ciacci, María Belén.

El uso de nanofertilizantes impacta en el porcentaje de micorrizacion y rendimiento de soja

PosterEn la región de Cerrado, Rio Verde Goiás- Brasil, los productores rurales buscan aumentar la productividad del cultivo de soja de forma eficiente. En este sentido, el empleo de nanofertilizantes causa un gran impacto, ya que estos mejoran la producción agrícola utilizando bajas dosis en formulaciones liquidas compatibles con otros insumos. El objetivo de este trabajo fue evaluar, como afecta la aplicación complementaria de nanofertilizantes en la siembra (MIST-P y MIST-TPS) sobre el porcentaje de micorrización y rendimiento en soja en áreas agrícolas de Rio Verde Goiás- Brasil.Instituto de Fisiología y Recursos Genéticos VegetalesFil: Ciacci, María Belén.

SOX2 and BCL-2 Expressions in Odontogenic Keratocyst and Ameloblastoma

The purpose of this experimental study was to compare the immunohistochemical expression of SOX2 and BCL-2 in Odontogenic Keratocyst (OKC) and Ameloblastoma (AB) specimens, and to identify a possible correlation in their expression. Immunohistochemical analysis was performed to evaluate SOX2 and BCL-2 expression in OKC (n = 20) and AB (n = 20). The immunoexpression was analyzed by a quantitative and qualitative scoring system. The comparison between the immunoexpression of SOX 2 and BCL-2 was assessed by the Mann-Whitney U-test. Spearman?s correlation coefficient evaluated the correlation between SOX2 and BCL-2 expressions. SOX2 and BCL-2 expression was observed in all specimens of OKC in the full thickness of the epithelium lining. SOX2 immunostaining was higher in OKC, in comparison with AB samples (P<0.05). BCL-2 immunostaining between OKC and AB was not statistically significant. There was no significant correlation between SOX2 and BCL-2 in OKC and AB specimens. SOX2 and BCL-2 expressions in OKC may suggest their relationship with the biological behavior of this lesion, and the higher expression of SOX2 might be an upstream influence on the Hh signaling pathway

Nanofertilizantes no cultivo do milho safrinha

Three Cases of Exclusively Extragenital Canine Transmissible Venereal Tumor (cTVT)

Background: Canine Transmissible Venereal Tumor (cTVT) is a neoplasia that affects mainly the genital organs of dogs, but can rich extragenital sites as well. It´s a tumor characterized microscopically by the presence of vacuolized round cells. Transmission occurs by implantation of these cells in non-affected tissues and the treatment is based on vincristine chemotherapy.Cases: Case 1. A 5-year-old intact male Poodle, presenting an increase volume of nasal plane came for veterinary care at a private veterinary clinic. The animal had bilateral bloody nasal secretion and dyspnea. The external genitalia had no alterations. The cytological evaluation confirmed cTVT. Treatment with vincristine sulfate weekly showed a rapid responsewith improvement of the respiratory condition, total remission of the mass and absence of neoplastic cells in cytology. Case 2. A 5-year-old mixed-breed canine bitch, weighing 6.7 kg, was brought to the State University of Santa Cruz Veterinary Hospital (UESC-VH), showing an increase volume in the nasal plan region, with complaints about sneezing, nasal bleeding,respiratory distress with approximately 4 months of evolution. The owner informed that the mother of these female dog, that lived in the same environment, died a month before the beginning of clinical signs of the bitch of this case, and showed a reddish vaginal mass with intense bleeding. Intranasal exfoliative cytology showed moderately cellular sample compatible with cTVT. The treatment with vincristine sulphate for 6 weeks, showed completely remission of all clinical signs. Case 3. A 3-year-old mixed-breed male dog was brought to the UESC-VH with a reddish, friable mass located in the left eye. The citology confirmed the clinical suspicion of cTVT. After six weekly sessions of chemotherapy with vincristine sulfate, the tumor regressed and a new cytological evaluation was performed, without visible of tumor cells. By the end of the treatment, the dog was diagnosed with phitisis bulbi, and one year later, due to recurrent ulcerative keratitis, the enucleation was performed and the histopathological examination of the eye did not identify the presence of tumor cells.Discussion: Two of the dogs cited in this report had freely streets access, without supervision of the owners, and they are likely to have contracted cTVT on one of those occasions. The animal’s care style acts as a risk factor for the development of neoplasia. Regarding the third animal, the close contact with another female dog, who had compatible vaginal cTVTclinical signs was probably the factor that determined the transmission. None of the animals cited in this report had lesions on their external genitalia. The extragenital presentation may be attributed to the social behavior of licking and sniffing the genitalia of carrier animals, which may lead to the natural implantation of the viable cells of the cTVT into the ocular and nasal mucosa. About the clinical signs manifested, in the cases of involvement of the nasal structures, the main signs described in literature are bloody nasal secretion, sneezing, dyspnea and increased nasal plane volume, and are similar to those observed in the animals cited in this report. In the case of ocular cTVT, the increase volume with impairment and deformity of all ocular structures, as well as pain and pruritus corroborate with the clinical findings observed in the literature. The cytopathological test was the diagnostic tool used in all cases cited in this report and the cytopathological findings corroborates with those described in the literature. Vincristine sulfate is the drug of choice for the treatment of cTVT cases, and in the dogs of this report, this drug was successfully used leading to complete remission of lesions and clinical signs, as observed in other studies.Keywords: nasal mucosa, ocular mucosa, venereal disease, round cells
