Spine Neuroimaging: Computed Tomography Diagnostic Signs
Barata Tavares, Joana; Santos, Carolina M; Cordeiro, Inês; Reimão, Sofia; Campos, Jorge GIntroduction: Computed tomography (CT) scans of the spine are among the most frequently performed neuroradiologic exams, studying several pathologies namely degenerative diseases. Specific signs in spine imaging initially described in conventional radiology can be applied to CT scans. The main goal of this work was their identification and characterization. Methods: A review of the main imagiological signs in C...
Essential oil composition of fruit colour varieties of eugenia brasiliensis lam.
Moreno, Paulo Roberto Hrihorowitsch; Lima, Marcos Enoque Leite; Sobral, Marcos Eduardo Guerra; Young, Maria Cláudia Marx; Cordeiro, InêsA espécie Eugenia brasiliensis Lam. apresenta a coloração dos frutos variável, sendo reconhecidas três variedades. Entretanto, a definição de variedades não é fácil para espécies de Myrtaceae e também não é amplamente aceita. Duas variedades de Eugenia brasiliensis, baseado na cor dos frutos (roxos e amarelos), tiveram a composição de seus óleos essenciais analisadas com a finalidade de obter indícios de varied...
Chemical composition and acetylcholinesterase inhibitory activity of essential ...
Souza,Amanda de; Lopes,Elaine M. Cardoso; Silva,Michelle C. da; Cordeiro,Inês; Young,Maria Cláudia M.; Sobral,Marcos E. G.; Moreno,Paulo R. H.The chemical composition of volatile oils from two Myrtaceae species, Myrceugenia myrcioidesand Eugenia riedeliana, both native from the Brazilian Atlantic Rain Forest, was analyzed by GC-MS. Acetylcholinesterase inhibitory activity was colorimetrically evaluated for these oils. For M. myrcioides, monoterpene hydrocarbons represented the major class in the volatile oil, with α-pinene as the most abundant c...
Incorrect DNA methylation of the DAZL promoter CpG island associates with defec...
Navarro-Costa, Paulo; Nogueira, Paulo; Carvalho, Marta; Leal, Fernanda; Cordeiro, Inês; Calhaz-Jorge, Carlos; Gonçalves, João; Plancha, Carlos E.Versão impressa: Hum Reprod. 2010 Oct;25(10):2647-54 ; Background: Successful gametogenesis requires the establishment of an appropriate epigenetic state in developing germ cells. Nevertheless, an association between abnormal spermatogenesis and epigenetic disturbances in germline-specific genes remains to be demonstrated. Methods: In this study, the DNA methylation pattern of the promoter CpG island (CGI) of ...
Screening for antifungal, DNA-damaging and anticholinesterasic activities of Br...
Lopes,Elaine Monteiro Cardoso; Carreira,Rosana Cristina; Agripino,Débora Gomes; Torres,Luce Maria Brandão; Cordeiro,Inês; Bolzani,Vanderlan da SilvaCrude extracts from 17 plant species collected from an Atlantic Forest region in the State of São Paulo (Brazil) have been screened for antifungal, DNA-damaging and acetylcholinesterase inhibiting activities. Of the 34 extracts obtained from leaves and stems of plants assayed for antifungal activity with Cladosporium sphaerospermum and C. cladosporioides 26.5% were active. However, only the extract of leaves of...
Essential oil composition of fruit colour varieties of Eugenia brasiliensis Lam.
Moreno,Paulo Roberto H.; Lima,Marcos Enoque Leite; Sobral,Marcos; Young,Maria Cláudia Marx; Cordeiro,Inês; Apel,Miriam Anders; Limberger,Renata PereiraEugenia brasiliensis Lam. is a variable species concerning fruit colour, with three recognized varieties. However, the definition of varieties is not easy for Myrtaceae species and not widely accepted. Two fruit colour varieties (purple and yellow) of E. brasiliensis had their essential oil composition analysed in order to give support to the existence of varieties for this species. Although, the major componen...
