13. Comparison of multiple genotyping methods for the identification of the cancer predisposing founder mutation p.R337H in TP53
Abstract Germline mutations in the TP53 gene are associated with Li-Fraumeni and Li-Fraumeni-Like Syndromes, characterized by increased predisposition to early-onset cancers. In Brazil, the prevalence of the TP53-p.R337H germline mutation is exceedingly high in the general population and in cancer-affected patients, probably as result of a founder effect. Se

14. Recognition of heart sound based on distribution of Choi-Williams
IntroductionTo realize noninvasive diagnosis and early diagnosis of coronary heart disease, the study proposes a new time-frequency method for analyzing heart sound signals. This method is based on Choi-Williams Distribution (CWD).MethodsCWD distribution is developed and modified from Wigner Ville distribution (WVD). To solve the problem of cross-term interf

15. Investigating alpha-globin structural variants: a retrospective review of 135,000 Brazilian individuals
Background: Brazil has a multiethnic population with a high diversity of hemoglobinopathies. While screenings for beta-globin mutations are far more common, alterations affecting alpha-globin genes are usually more silent and less well known. The aim of this study was to describe the results of a screening program for alpha-globin gene mutations in a repres

16. De novo alpha 2 hemoglobin gene (HBA2) mutation in a child with hemoglobin M Iwate and symptomatic methemoglobinemia since birth
Cyanosis in an apparently healthy newborn baby may be caused by hemoglobin variants associated with the formation of methemoglobin, collectively known as M hemoglobins. They should not be confused with genetic alterations in methemoglobin reductase enzyme systems of red cells since treatment and prognosis are completely different. A newborn male child was no

19. The performance of four molecular methods for the laboratory diagnosis of congenital toxoplasmosis in amniotic fluid samples
Introduction Toxoplasmosis may be life-threatening in fetuses and in immune-deficient patients. Conventional laboratory diagnosis of toxoplasmosis is based on the presence of IgM and IgG anti-Toxoplasma gondii antibodies; however, molecular techniques have emerged as alternative tools due to their increased sensitivity. The aim of this study was to compare

20. Desempenho cognitivo de pacientes com neuromielite optica: comparacao com esclerose multipla
The aim of the present research was to investigate cognitive pattern of patients with neuromyelitis optica (NMO) and to compare it with multiple sclerosis (MS) patients' performance. Methods: Fourteen NMO, 14 relapsing remitting multiple sclerosis (RRMS), and 14 healthy control patients participated in the investigation. Neuropsychological functions were eva

21. Auditory attention and fonological in childrens with cleft lip and palate with primary palatoplasty 9 to 12 months of age / Atenção auditiva e consciência fonológica em crianças com fissura labiopalatina com palatoplastia primária de 9 a 12 meses de idade
The cleft lip and palate is a congenital craniofacial malformation characterized by the lip and/or palate not joining. Several consequences can occur from this rupture such as alterations in speech, swallowing, chewing, dental and hearing. As a result of this, these patients need to undergo reconstructive surgeries, and the age it will happen is fundamental

24. Automatic hippocampus segmentation through similarity cloud / Segmentação da estrutura cerebral hipocampo por meio de nuvem de similaridade
The hippocampus is a particular structure that plays a main role in human memory systems. Tissue modifications of the hippocampus lead to neurodegenerative diseases as epilepsy, multiple sclerosis, and dementia, among others. To measure hippocampus atrophy, it is crucial to get its isolated representation from the whole brain volume. Separating the hippocamp
