Dynamic sequence evolution of a sex-Associated b chromosome in lake Malawi cichlid fish
(2017-01-01)
B chromosomes are extra chromosomes found in many species of plants, animals, and fungi. B chromosomes often manipulate common cellular processes to increase their frequency, sometimes to the detriment of organismal fitness. ...
Meiotic chromosome analysis in tropical orchid genus Sobralia
(2018)
Tropical orchid genus Sobralia comprises terrestrial plants with elongated, cane-like stems
and large symmetrical, yet ephemeral flowers. This genus is distributed throughout Central and South
America and may hold ...
Mapping the BDA20 Gene to BTAX
(Karger, 2008-01-01)
The lipocalin family is a large group of proteins that exhibits great structural and functional variation both within and among species, including a significant number of animal-derived aeroallergens, such as the bovine ...
Inferring paternal history of rural african-derived brazilian populations from y chromosomes
(Sociedade Brasileira de Genática - SBGÁguas de Lindóia, 2013-09-16)
About four million Africans were brought to Brazil as slaves during four centuries. Many communities, named
quilombos, were founded by runaway or abandoned African slaves. ere are many quilombo remnants in the ‘Vale ...
Identification and complete sequencing of novel human transcripts through the use of mouse orthologs and testis cDNA sequences
(2004-12-01)
The correct identification of all human genes, and their derived transcripts, has not yet been achieved, and it remains one of the major aims of the worldwide genomics community. Computational programs suggest the existence ...
Dysregulated expression of mitotic machinery genes precedes genome instability during spontaneous pre-malignant transformation of mouse ovarian surface epithelial cells
(2016)
Based in epidemiological evidence, repetitive ovulation has been proposed to play a role in the origin of ovarian cancer by inducing an aberrant wound rupture-repair process of the ovarian surface epithelium (OSE). ...
A Model Based on Genetic Algorithm for Colorectal Cancer Diagnosis
(2019-01-01)
In this paper we present a method based on genetic algorithm capable of analyzing a significant number of features obtained from fractal techniques, Haralick texture features and curvelet coefficients, as well as several ...
Emergence of sensory selection mechanisms in Artificial Life simulations
(London, 2008)
Background
The evolutionary advantages of selective attention are unclear. Since the study of selective attention began, it has been suggested that the nervous system only processes the most relevant stimuli because of ...
