Members of the Herpesviridae family have been implicated in a number tumours humans. At least 75% human population has had contact with cytomegalovirus (HCMV). In this work, we screened 75 Brazilian glioma biopsies for presence HCMV DNA sequences. was detected 36% (27/75) biopsies. It is possible that could be co-factor evolution brain tumours.
Multidrug resistance in gliomas is the major challenges clinical setting. We investigated expression of P-glycoprotein (Pgp) and multidrug resistance-related protein 1 (MRP1) 50 using immunohistochemistry. Compared to Pgp, MRP1 positivity was observed highest percentage grade IV samples (p = 0.008). Unlike high-grade, II exhibited a greater number Pgp positive as compared grades III 0.026). Our results suggest that difference between histological regarding must have implications choice...
The Epstein-Barr virus (EBV) is the most common cause of infectious mononucleosis and also associated with several human tumors, including Burkitt's lymphoma, Hodgkin's some cases gastric carcinoma nasopharyngeal carcinoma, among other neoplasms. aim this study was to screen 75 primary gliomas for presence specific EBV DNA sequences by means polymerase chain reaction (PCR), confirmation direct sequencing.Prevalence on molecular genetics at a pathology laboratory in university hospital an...
Treatment of intracranial tumoral lesions is related to its correct histological diagnostic. We present a retrospective analysis 32 patients submitted 36 cerebral biopsies using neuronavigation and 44 frame-based stereotaxy. Mean age was 46.6 49.3 years old respectively. Sex distribution in both groups 50% for each. Most were lobar groups. Diagnostic yielding 91.7% 83.4%, respectively (p=0.26). found the postoperative CT scans hemorrhages 13.8% cases first group 9.8% second. them mild...
A bstract : We have verified the presence of line‐1 retrotransposon (L1) in plasma DNA 15/17 brain tumor (glioma) patients and 6/6 healthy people by applying PCR amplification part L1 5′ end. The same samples were separately amplified for K‐ras . Results suggested that sequences are circulating throughout body. hypothesized participation transposable elements such as a putative release mechanism.
Snoring and apnea are social medical problems that affect as many 2% of adult women 4% men. This study compares collagen distribution type with the intensity snoring degree drowsiness following uvulopalatoplasty CO2 laser radiofrequency ablation.Fragments were taken from soft palate by biopsies 16 patients 5 controls, weeks after surgery, they stained Sirius red observed polarization microscopy. Photographs taken, changes in amount before surgery compared.A histological analysis...
The presence of zinc in the auditory pathways and its probable participation tinnitus hearing loss are known facts, although there no clinical trials experimental studies showing impact hypozincemia vestibular system existence pathway, respectively.This study is an attempt to correlate abnormal function.This a retrospective case where nine patients suffering chronic deficiency had their serum determined were submitted videonystagmography. Results compared normal (control) group.All test...
Sudden unexpected death in epilepsy (SUDEP) is the leading cause of patients with refractory epilepsy. There still a debate literature if respiratory arrest primary death. Respiratory chemoreceptors neurons located retrotrapezoid nucleus (RTN) constitute one main groups responsible for controlling breathing automaticity and receive dense serotonergic innervation. Here, we ask whether alterations type chemoreceptor that expresses transcription factor Phox2b non‐catecholaminergic (Phox2b + /TH...

The participants met criteria were selected from enrollment list later interviewed person through questionnaire containing 26 open closed questions divided into two groups: I-Socioeconomic...
