Otimização de protocolo para detecção de DNA de Trypanosoma cruzi em polpa de açaí (Euterpe oleracea)
Protocol optimization for the detection of Trypanosoma cruzi DNA in açai (Euterpe oleraceae) pulp

Acta amaz; 51 (1), 2021
A doença de Chagas, enfermidade causada pelo protozoário Trypanosoma cruzi, tem sido relacionada com frequência à transmissão oral pelo consumo de açaí. Métodos moleculares que fornecem uma identificação rápida e precisa do patógeno para a detecção da presença do parasita são de extrema...

Analysis of the population structure and genetic diversity of the red swamp crayfish (Procambarus clarkii) in China using SSR markers

BACKGROUND: Procambarus clarkii produces high-quality, delicious meat that is high in protein, low in fat, and rich in calcium and phosphorus. It has become an important aquatic resource in China. Our objectives are (i) to analyze the level of genetic diversity of P. clarkii populations; (ii) to explore ...

Biomédica (Bogotá); 40 (2), 2020
Introducción. La fibrosis quística es una enfermedad genética de carácter autosómico recesivo clasificada como enfermedad huérfana de alto costo. Objetivo. Determinar la razón de costo-efectividad de la prueba diagnóstica de secuenciación del gen CFTR para los portadores asintomáticos familiare...

Avances en el diagnóstico de la enfermedad granulomatosa crónica: primer estudio familiar en Cuba
Advances in the diagnosis of chronic granulomatous disease: the first family study in Cuba

Introducción: La enfermedad granulomatosa crónica es una inmunodeficiencia primaria causada por mutaciones en la enzima NADPH oxidasa. Esta compromete la producción de especies reactivas del oxígeno, que son importantes contra patógenos. La prueba de la oxidación de la dihidrorodamina es un método...

Enfermedad por hemoglobina H: primer caso de dobles heterocigotos hemoglobina Constant Spring / Sudeste Asiático en Costa Rica

Acta méd. costarric; 62 (1), 2020
Resumen La enfermedad por hemoglobina H es un cuadro clínico que se presenta en las alfa talasemias, las cuales son enfermedades que cursan con anemia microcítica hipocrómica, debidas principalmente a deleciones en el gen de alfaglobina, lo que disminuye la producción de la cadena de alfa globina y p...

Resumen En este reporte de caso se describe el primer paciente doble heterocigoto para alfa+-talasemia tipo -3,7 y rasgo heterocigoto por hemoglobina S en Costa Rica, diagnosticado desde su nacimiento por medio del tamizaje neonatal como heterocigoto para hemoglobina S. Luego de la detección de la hemog...

A pioneering RET genetic screening study in the State of Ceará, Brazil, evaluating patients with medullary thyroid cancer and at-risk relatives: experience with 247 individuals

ABSTRACT Objective: Initial diagnosis of medullary thyroid carcinoma (MTC) is frequently associated with advanced stages and a poor prognosis. Thus, the need for earlier diagnoses and detection in relatives at risk for the disease has led to increased use of RET genetic screening. Subjects and methods:...

Clinical features of carriers of reciprocal chromosomal translocations involving chromosome 2: report of nine cases and review of the literature

Int. braz. j. urol; 44 (4), 2018
ABSTRACT Objective: To explore the clinical features of carriers of chromosome 2 translocations, enabling informed genetic counseling of these patients. Materials and Methods: Eighty-two male carriers of a translocation who were infertile or receiving fertility counseling were recruited. Cytogenetic an...

Evidence of heterozygosity and recombinant alleles in single cysts of Giardia duodenalis

Abstract Giardia duodenalis is divided into eight assemblages (named A to H). Isolates of assemblage A are divided into four sub-assemblages (AI, AII, AIII and AIV). While isolates of sub-assemblage AII are almost exclusively detected in human hosts, isolates of assemblage B are encountered in a multitud...

The frequency of Tay-Sachs disease causing mutations in the Brazilian Jewish population justifies a carrier screening program

Säo Paulo med. j; 119 (4), 2001
CONTEXT: Tay-Sachs disease is an autosomal recessive disease characterized by progressive neurologic degeneration, fatal in early childhood. In the Ashkenazi Jewish population the disease incidence is about 1 in every 3,500 newborns and the carrier frequency is 1 in every 29 individuals. Carrier screenin...
