Radiotherapy, cancer and some anatomical structures related with the pelvic floor: an evaluation of the scientific literature
Radiotherapy is a cancer treatment that uses high-energy X-rays or other types of ionizing radiation to try to kill the cancer cells in various organs/tissues. PubMed is a database used as a tool in various publications. The aim of this work was to evaluate, in the PubMed, the number of publications (NP) in radiotherapy and cancer in various organs related to the pelvic floor as well as brachytherapy. The searches were performed (August 2008) in the PubMed (http://www.pubmed.com) using the words: (i) radiotherapy (RT) or cancer (CA), (ii) RT and CA, (iii) RT and CA and prostate, RT and CA and testis, RT and CA and breast, RT and CA and kidneys, RT and CA and vulva, RT and CA and vagina, RT and CA and penis, RT and CA and uterus, RT and CA and ovary, RT and CA and bladder, and RT and CA and urethra. A search using brachytherapy was also performed. The NP in each subject was determined and was 2178635 to CA and about 9% of them are related with RT. The NP in RT and CA and breast or prostate is bigger than for the other organs, whereas brachytherapy is mainly cited in the studies about CA of prostate, bladder and breast. In conclusion, our findings demonstrate the importance of radiation therapy studies in the cancer of several organs. This information is crucial in understanding the field and demonstrates areas of significant progress or existing gaps of research in radiotherapy treatment of various cancers of the pelvis. Furthermore, it could significantly aid the interprofessional team in the determination of actions related to the treatment of patients that are undertaking radiotherapy, due to the possible complications of this modality of treatment
Management factors associated with bovine tuberculosis on dairy herds in Rio de Janeiro, Brazil.
ABSTRACT - With the purpose of identifying management factors that may be influencing the prevalence of bovine tuberculosis under tropicalconditions, namely in Rio de Janeiro, Brazil, 1632 cows were tested through the single cervical tuberculin test. A questionnairewas completed for each herd. A total of 207 positive reactions were observed, corresponding to 12.7% of the studied cattle. Themain factors observed that may be influencing the prevalence of bovine tuberculosis on those farms were the absence orreduced veterinary assistance and the herd size. The presence of adequate cattle houses and the highly intensive managementare also considered to be likely to influence the prevalence of the disease. Under tropical conditions, a tuberculosis controlprogram, in addition to the test-and-slaughter control method, should include an investigation of herd management practices totry to identify factors that are likely to influence the prevalence of the disease. RESUMO - Com o objetivo de identificar fatores que possam influenciar a prevalência de tuberculose bovina em condições tropicais, emespecial no Rio de Janeiro, Brasil, 1632 vacas foram testadas pelo teste intra dérmico simples com tuberculina bovina. Um questionário foi completado para cada rebanho. Um total de 207 reações positivas foi observado, o que correspondeu a 12,7%do gado estudado. Os principais fatores observados que podem influenciar na prevalência de tuberculose bovina nestes rebanhos foram a ausência ou reduzida assistência veterinária e o tamanho do rebanho. A presença de estábulos adequados e o manejo intensivo também foram considerados como fatores que podem influenciar na prevalência da enfermidade. Em condições tropicais, um programa de controle da tuberculose deve, além do método de teste-e-abate, incluir uma investigação das práticas de manejo adotadas no rebanho a fim de tentar identificar fatores que possam influenciar na prevalência da enfermidade
Effects of consumption of galactooligosaccharides obtained through whey enzymatically modified on the faecal flora and nutritional parameters of hamsters
The aim of this research was to evaluate the influence of wheyenzymatically modified rich in galactooligosaccharides in thenutritional characteristics and effects in the microflora of cecumcontents by the study with Golden Syrian hamsters (Mesocricetusauratus) for 28 days (controlled conditions). Three isoproteic dietswere prepared (20% w/w): C (casein), W (whey) and G (wheymodified). The groups studied differed positively from the C regardingfeed and protein efficiency ratio. The relationships (w/w) oforgan/body were found proportional in all diets. The counts ofprobiotics from the cecum contents the groups showed no difference.The pHs of studied groups were lower than C, this acidity can atimpairs the ability of pathogens to grow in the intestine. Resultssuggest that using whey enzymatically modified rich ingalactooligosaccharides could replace the standard diet withnutritional efficiency and possible inhibit the microorganismspathogenic without induce damage in health.Fil: Dos Santos Da Fonseca, Renata Aline.

Genetic variability of Melipona subnitida (Hymenoptera: Apidae) in introduced and native populations.
Melipona subnitida (Hymenoptera: Apidae) is a stingless bee native to Caatinga biome in Brazil, well adapted to hot and dry climate of that region and has been traditionally explored for honey production. Here, we evaluate the genetic structure of 173 colonies of M. subnitida in northeast Brazil by partially sequenced mitochondrial genes cytochrome oxidase I (COI) to compare an introduced population isolated for 30 yr into the Island of Fernando de Noronha (IFN) with the continental populations. We identified high haplotype diversity (0.8220) with 14 haplotypes on the continental populations, being three new ones, compared with the database GenBank. The haplotype H4 was present at the center of network, occurring in four localities on mainland and fixed as a single haplotype on IFN. We propose that the island populations originally introduced carried one haplotype (H4), even though IFN population is suffering pressure by island effect through changes on morphology. Studies on island populations could be a model to understand the dynamics of isolated populations and sustainable management of this biome to preserve M. subnitida
BRSMT Vencedora: cultivar semiprecoce de arroz de terras altas.
A BRSMT Vencedora é uma cultivar de produtividade similar à das principais variedades em cultivo nas terras altas, porém, apresenta, em relação a cada uma delas, vantagens importantes que a transformam em uma opção de cultivo relevante. Esta cultivar está sendo recomendada para plantio nos Estados de Goiás, Minas Gerais, Mato Grosso do Sul, Mato Grosso, Roraima e Pará.bitstream/item/60526/1/Comt72.pd
