10Anal canal gastrointestinal stromal tumors:Case report and literature review显示文摘Gastrointestinal stromal tumors(GIST)are an uncommon group of tumors of mesenchymal origin.GIST of the anal canal is extremely rare.At present,only 10cases of c-kit positive anal GIST have been reported in the literature.There is no widely accepted treatment approach for this neoplasia.Literature is sparse on imaging evaluation of anal canal GIST,usually described as a lesion in the intersphincteric space.We describe the case of a 73-year-old man with a mass in the anal canal,and no other symptoms.Endoanal ultrasound and magnetic resonance imaging showed a well circumscribed solid nodule in the intersphincteric space.The patient was treated by local excision.Gross pathological examination showed a 7 cm×3.5 cm×3cm mass,and histological examination showed a proliferation of spindle cells,with prominent nuclear palisading.The mitotic count was of 12 mitoses/50 HPF.The tumor was positive for KIT protein,CD34 and vimentin in the majority of cells,and negative for desmin and S100.A diagnosis of GIST,with high risk aggressive behavior was made.An abdomino-perineal resection was discussed,but refused.The follow-up included clinical evaluation and anal ultrasound.After 5 years the patient is well,with maintained continence and no evidence of local recurrence.Nuno Carvalho Diogo Albergaria Rui Lebre Joo Giria Vitor Fernandes Helena Vidal Maria José Brito 2014World Journal of Gastroenterology2014,20,1:1
11Nutritional supplements use in high-performance athletes is related with lower nutritional inadequacy from food显示文摘Background: The use of nutritional supplements(NS) among athletes is widespread. However, little is known about the relationship between nutritional adequacy and NS usage. The aims of this study were to evaluate the NS usage and to compare the nutritional intake from food and prevalence of micronutrient inadequacy(PMI) between NS users and non-users.Methods: Portuguese athletes from 13 sports completed an NS usage questionnaire and a semi-quantitative food-frequency questionnaire assessing information over the previous 12 months. The estimated average requirement cut-point method was used to calculate PMI. General linear models were used to compare nutritional intake and NS usage. Chi-squared tests and logistic regression were performed to study, respectively,relationships and associations between PMI and NS usage.Results: From the 244 athletes(66% males, 13–37 years), 64% reported NS usage. After adjustment, NS users showed a higher intake from food(p < 0.05), for at least 1 gender, for energy, and for 7 of the 17 studied nutrients. The highest PMI were seen for vitamins D and E, calcium, folate,and magnesium. After adjustment, NS users, irrespective of gender, reported lower PMI for calcium(OR = 0.28, 95%CI: 0.12–0.65), and female users for magnesium(OR = 0.06, 95%CI: 0.00–0.98).Conclusion: Athletes using NS reported a higher nutritional intake from food, and a lower PMI for several nutrients. Perhaps, those who were taking NS were probably the ones who would least benefit from it.Mónica Sousa Maria J.Fernandes Pedro Carvalho José Soares Pedro Moreira Vitor Hugo Teixeira 2016Journal of Sport and Health Science2016,5,3:0

14Parasite Fauna of Lutjanus synagris Commercialized in the Fish Market from Bragança-PA,Brazil显示文摘Studies about the parasite fauna of marine fish highlights as an important problem for public health with zoonotic parasites or affecting the fish quality.Thus,this study evaluated the parasite fauna of Lutjanus synagris commercialized in the fish market from Bragança-PA.In laboratory,58 fish were measured,weighted and conducted to parasitological analysis to determine parasitological indexes and relative dominance.Every parasite was fixed and identified until to the lowest taxonomic level.Through the parasitological analysis,it found Cymothoidae,Digenea,Cucullanus sp.and Procamallanus(Spirocamallanus)sp.,with total prevalence 67.24%.Digenea showed the highest prevalence and mean intensity values.For nematode,Cucullanus sp.obtained the greater prevalence and relative dominance,while Procamallanus(Spirocamallanus)sp.showed the greater mean intensity and abundance.Cymothoidae showed the lowest prevalence and mean intensity values.As conclusion,the parasite fauna of L.synagris has been noted with low diversity,reporting the nematode occurrence Procamallanus(Spirocamallanus).Natalino da Costa Sousa Daiana Silva dos Santos Silmara Rosa Silva Alexandre Vaz da Silva Jucimauro de Araújo P.Junior João Vitor Antunes Miranda Pedro Rodrigo Nery de Souza Matheus Carvalho de Melo Fagner de Melo Xavier Wellington Lima da Silva Junior Fabricio Ramos Menezes Márcia Valeria Silva do Couto 2019Journal of Zoological Research2019,1,3:0
15Formation of DNA Strand Breaks in Peripheral Lymphocytes of Rats After Exposure to Natural Sunlight显示文摘Objective This paper aims to evaluate the genotoxicity in peripheral blood lymphocytes of rats after exposure to sunlight at different time points of day in a tropical region of Brazil(5oS,42oW).Materials and Methods Thirty Wistar-Hannover rats,three months old,were randomly divided into three groups of 10 animals each:Group I [control,without exposure to ultraviolet(UV) radiation],Group II(exposed to sunlight during 08:00 a.m.to 10:00 a.m.),and Group III(exposed to sunlight during 10:00 a.m.to 12:00 a.m.).After a week of exposure,peripheral blood samples were taken from the tail of these animals to prepare smears on two slides per animal.In 24 h after exposure to sunlight in Group III,a new collection was obtained to observe the repair activity.The alkaline comet assay was used in this study to evaluate the genotoxic activity of sunlight(P<0.05).Results There was no statistical difference between Group I and II(P=0.672).On the other hand,the exposure to sunlight in Group III showed genotoxic action in comparison to the other groups(P<0.0001).Also,there was no significant repair in Group III R(P=0.407).Conclusion This study has shown a genotoxic potential of sunlight(UVA-B) in lymphocytes of mammals from 10:00 a.m.to 12:00 a.m.,due to a higher intensity of UV in this tropical region.Dorival Mendes RODRIGUES-JUNIOR Ana Amélia de CARVALHO MELO Benedito Borges da SILVA Pedro Vitor LOPES-COSTA 2012Biomedical and Environmental Sciences2012,25,2:0

17Case report of a criminal dismemberment in Northeast Brazil显示文摘Several decomposed body parts were received for examination by the Forensic Anthropology section of the Medico-legal Institute of João Pessoa,Paraíba,Brazil.The portions of the lower and upper limbs,ribs,vertebrae,and a skull were thoroughly examined.The biological profile indicated a male individual with an estimated age range between 23 and 57 years and a mean age of 35.2 years(SD=9.4;phase IV,Suchey-Brooks).The skeleton showed injuries caused by sharp force and sharp-blunt force trauma that affected all body segments.Macroscopically,the lesions are mainly in the diaphyseal segments of the long bones,sacrum,pelvis,mandible,maxilla,scapulae,sternum,vertebrae,the distal epiphysis of the left fibula,and the distal epiphysis of the left tibia displayed characteristics compatible with injuries produced perimortem.It was not possible to determine the cause of death.DNAanalysis resulted in a positive identification.Because of common difficulties faced in forensic practice,it is often not possible for forensic anthropologists to go to the crime scene,X-ray or body scanners are frequently unavailable,and the victim’s medical and/or dental records are sometimes absent.These difficulties make identification ultimately depend on genetic analysis,which is more time-consuming than other identification methods.Despite this,bone fragment examination in dismemberment cases is a complex task.Forensic Anthropology can shed light on cases involving the identification of dismembered remains,which are challenging because of the number of traumatic injuries,as well as different injury patterns,on bones.Evelyne Pessoa Soriano Maria do Socorro Dantas de Araújo Francisca de Assis Nascimento Pereira Francisca Divina Silveira de Melo Cristiane Helena da Silva Barbosa Freire Marcus Vitor Diniz de Carvalho 2022Forensic Sciences Research2022,7,4:0
