Hemotropic Mycoplasma and Bartonella Species Diversity in Free-Roaming Canine a...
Mesquita, JR; Oliveira, AC; Neves, F; Mendoza, JR; Luz, MF; Crespo, I; Dos Santos, TF; Santos-Silva, S; Vilhena, H; Barradas, PFFree-roaming dogs and cats represent potential reservoirs for zoonotic vector-borne pathogens shedding to the human population. Given the health impact of these pathogens, we searched free-roaming dogs and cats included in an animal population control program from Luanda, Angola, for Bartonella and hemotropic mycoplasma infection. We report the detection of Bartonella henselae (2/66; 3%), Candidatus Mycoplasma ...
Amplified and Homozygously Deleted Genes in Glioblastoma: Impact on Gene Expres...
Crespo, I; Tão, H; Nieto, AB; Rebelo, O; Domingos, P; Vital, AL; Patino, MC; Barbosa, MD; Lopes, MC; Resende de Oliveira, C; Orfão, A; Tabernero, MDBACKGROUND: Glioblastoma multiforme (GBM) displays multiple amplicons and homozygous deletions that involve relevant pathogenic genes and other genes whose role remains unknown. METHODOLOGY: Single-nucleotide polymorphism (SNP)-arrays were used to determine the frequency of recurrent amplicons and homozygous deletions in GBM (n = 46), and to evaluate the impact of copy number alterations (CNA) on mRNA levels of...
Intratumoral patterns of clonal evolution in gliomas
Vital, AL; Tabernero, MD; Crespo, I; Rebelo, O; Tão, H; Gomes, F; Lopes, MC; Orfão, AFew studies have explored the patterns of clonal evolution in gliomas. Here, we investigate the cytogenetic patterns of intratumoral clonal evolution of gliomas and their impact on tumor histopathology and patient survival. Cytogenetic analysis of 90 gliomas was performed in individual tumor cells (>200 cells/tumor) using multicolor (N = 16 probes) interphase-FISH. Overall, chromosome gains were more frequent t...
