Development and significance of RAPD-SCAR markers for the identification of Litchi chinensis Sonn: by improved RAPD amplification and molecular cloning

Electron. j. biotechnol; 18 (1), 2015
Background Analysis of genetic diversity is important for the authentication of a species. Litchi (Litchi chinensis Sonn.) is a subtropical evergreen tree. Recently, L. chinensis has been characterized by an improved random amplified polymorphic DNA (RAPD) and inter-simple sequence repeat (ISSR) analysis...

Genetic diversity in two Italian almond collections

Electron. j. biotechnol; 18 (1), 2015
Background Sweet-seeded domesticated almonds were brought to the Mediterranean Basin from central Asia about 4000 years ago. In Italy, most of the almonds produced are cultivated in the southern part of the country. Local populations of the tree in Sardinia are largely seed-derived and mostly self-incomp...

Effect of nickel chloride on Arabidopsis genomic DNA and methylation of 18S rDNA

Electron. j. biotechnol; 18 (1), 2015
Background In recent years, nickel (Ni) has been widely applied in industrial and agricultural production and has become a kind of environmental pollution. In this study, the effect of nickel chloride (NiCl2) with different concentrations on Arabidopsis genomic stability and DNA methylation has been demo...

Identificação e estudo de biomarcadores personalizados para avaliação e seguimento de pacientes com câncer de reto tratados com quimioradioterapia neoadjuvante

O tratamento padrão para pacientes com câncer de reto localmente avançado consiste no uso de quimioradioterapia neoadjuvante (QRTn), seguida por cirurgia. Uma fração significativa dos pacientes responde completamente ao tratamento e no momento da reavaliação não apresenta evidência clínica nem ...

Estudo dos mecanismos moleculares do reparo de quebra de duplas fitas no DNA mitocondrial

O DNA está constantemente exposto a danos causados tanto por agentes endógenos quanto exógenos. Estes podem causar diferentes tipos de lesões incluindo modificações de bases e do açúcar, além de quebras de fitas simples ou duplas. As quebras de duplas fitas, quando comparadas às demais, constit...

Diagnóstico paleoparasitológico de protozoários do gêneroLeishmania Ross, 1903 (Kinetoplastida, Trypanosomatidae)em material arqueológico da América do Sul

Espécies do gênero Leishmania (Kinetoplastida, Trypanosomatidae) são agentescausadores de leishmanioses, que representam um complexo de doenças com variado espectroclínico e diversidade epidemiológica que, em alguns países, constituem-se em grave problema de saúde pública. A origem e evolução ...

Variación diurna en la composición del bacterioplancton y daño del ADN en la comunidad microbiana de un lago oligotrófico andino
Diurnal variation in bacterioplankton composition and DNA damage in the microbial community from an Andean oligotrophic lake

Rev. argent. microbiol; 46 (4), 2014
Laguna Azul is an oligotrophic lake situated at 4,560 m above sea level and subject to a high level of solar radiation. Bacterioplankton community composition (BCC) was analysed by denaturing gradient gel electrophoresis and the impact of solar ultraviolet radiation was assessed by measuring cyclobutane ...

Medication adherence and quality of life among the elderly with diabetic retinopathy

Rev. latinoam. enferm; 22 (6), 2014
METHOD: one hundred (n=100) elderly outpatients with diabetic retinopathy taking antihypertensives and/or oral antidiabetics/insulin were interviewed. Adherence was evaluated by the adherence proportion and its association with the care taken in administrating medications and by the Morisky Scale. The Na...

A case of thyroid hormone resistance: a rare mutation

Reduced sensitivity to thyroid hormones (RSTH) is a rare disease that affects about 3,000 individuals, belonging to about 1,000 families. It results from reduced intracellular action of thyroid hormones (TH) genetically determined and manifests as persistent hyperthyroxinemia with non-suppressed thyroid-...
