  • Transfer of LS chromosomes between otherwise genetically isolated strains explains the polyphyletic origin of host specificity and the emergence of new pathogenic lineages in F. oxysporum . (nature.com)
Protein2
  • T-box, brain, 1 is a transcription factor protein important in vertebrate embryo development. (wikipedia.org)
  • Gimap5 is a member of at least seven related GTPase Immune Associated Protein ( Gimap ) genes located within 150 Kilobases (Kb) on rat chromosome (RNO) 4 [ 2 , 3 ]. (hindawi.com)
19991
  • In the past, the International Olympic Committee (IOC) judged the gender of athletes based on chromosome examination, but with the continuous discovery of the medical community, the IOC gave up the method of judging the gender only by chromosome in 1999. (health-hot.com)
Strains3
  • Experimentally, we demonstrate the transfer of two LS chromosomes between strains of F. oxysporum , converting a non-pathogenic strain into a pathogen. (nature.com)
  • however, naturally occurring and engineered antimicrobial-resistant strains have been reported ( 3 - 5 ). (cdc.gov)
  • ABSTRACT The study evaluated the antimicrobial resistance of molecularly characterized strains of Staphylococcus aureus and S. saprophyticus isolated from 3 Lebanese dairy-based food products that are sometimes consumed raw: kishk, shanklish and baladi cheese. (who.int)
Inversion4
  • R-banding is a cytogenetic technique that produces inversion of G-band staining on chromosomes. (leatoc.pics)
  • 3 inversion, which generates ∼188 kb of directly oriented SDs with 99. (schleiden-eifel.de)
  • These are some of the most common cytogenetically visible rearrangements in humans - for example , the pericentric inversion of chromosome 9 is found in over. (schleiden-eifel.de)
  • A comparison of human and chimpanzee genes in the region of this inversion indicates that two genes-ROCK1 and USP14-that are adjacent on chimpanzee chromosome 17 (which corresponds to human chromosome 18) are more distantly positioned on human chromosome 18. (schleiden-eifel.de)
Extra genetic material1
  • This extra genetic material disrupts normal development, causing the characteristic features of this disorder. (medlineplus.gov)
Males2
  • B. This chromosomal aberration tends to manifest in males in the form of absent or delayed puberty, sterility, development of breast, etc. (schleiden-eifel.de)
  • Testosterone aids the development of secondary sex characteristics in males. (saralstudy.com)
Spindle2
  • In anaphase, each pair of chromatids separates into two identical chromosomes, which are pulled to opposite ends of the cell by spindle fibers. (leatoc.pics)
  • During telophase, chromosomes begin to decondense, the spindle breaks down, and nuclear membranes and nucleoli regenerate. (leatoc.pics)

Mutations4
  • Thus mutations in the Pax genes are important causes of human developmental defects. (nih.gov)
  • These data suggest that TP53 mutations may play a role in astrocytoma development and are predominantly associated with higher grade tumors. (nih.gov)
  • Consequently, several anterior segment dysgenesis phenotypes are associated with mutations in genes expressed during neural crest development. (molvis.org)
  • In humans, mutations in the L1 cell adhesion molecule are associated with a neurological syndrome termed CRASH, which includes corpus callosum agenesis, mental retardation, adducted thumbs, spasticity, and hydrocephalus. (jneurosci.org)
Disorders1
  • Some genetic diseases, such as haemophilia, are carried on the X-chromosome (these X-linked disorders occur mainly in men). (who.int)
Enables2
  • however, women only have X chromosomes, whilst men have both X and Y. The presence or absence of the Y chromosome enables biologists to determine the sex of an individual. (wikibooks.org)
  • Fluorescence "in situ" hybridization (FISH) technique enables chromosomes to be tagged with fluorescent dyes to highlight genetic traits. (lu.se)
Contributes1
  • During the process of brain development, there is an increase in the axonal connection which contributes to the growth of the brain. (bartleby.com)
Gonads2
  • The gonads which develop - the ovary and testes - are essential for the development of secondary sexual characteristics in the sexes, as they secrete sex-specific hormones. (wikibooks.org)
  • Pituitary gland secretes Gonadotropic hormone which stimulates the development of gonads. (learncram.com)
Tumor2
  • It affects cell proliferation, differentiation and inhibits apoptosis, and its role in tumor development has received attention ( 9 ). (spandidos-publications.com)
  • METHODS: Published data, consisting of 426 Liver tumor samples and 426 paired adjacent non-tumor samples, were re-analyzed to identify the integration sites. (bvsalud.org)
Syndrome7
  • Duplication of a region of the long (q) arm of chromosome 15 can result in 15q11-q13 duplication syndrome (dup15q syndrome), a condition whose features can include weak muscle tone (hypotonia), intellectual disability, recurrent seizures (epilepsy), and characteristics of autism spectrum disorder affecting communication and social interaction. (medlineplus.gov)
  • Dup15q syndrome is caused by the presence of at least one extra copy of a region of chromosome 15 called 15q11.2-q13.1. (medlineplus.gov)
  • People with dup15q syndrome resulting from an interstitial duplication often have milder signs and symptoms than those in whom the disorder results from an isodicentric chromosome 15. (medlineplus.gov)
  • The phenotype of the L1 mutant mouse indicates that it is a potentially valuable model for the human CRASH syndrome. (jneurosci.org)
  • Down syndrome is a genetic condition that causes delays in mental and physical development. (wewantscience.com)
  • Down syndrome is caused by an extra chromosome, affecting how the body and brain develop. (wewantscience.com)
  • This test checks if there is an extra chromosome in the baby's DNA, called trisomy 21, or an extra chromosome that is not part of trisomy 21 (called mosaic Down syndrome). (wewantscience.com)
Developmental1
  • These include involvement in the developmental process, brain development, neuronal differentiation, axon guidance, and regulation of neurons in the developing neocortex. (wikipedia.org)
Liver2
  • UDS activity in the rat liver of the human carcinogens benzidine and 4-aminobiphenyl, and the rodent carcinogens 3,3'-dichlorobenzidine and direct black 38. (cdc.gov)
  • or each of these agents, carcinogenicity in rats and/or mice, els, differences in exposure con- there was sufficient evidence of car- for example for the liver (aflatoxins, ditions between studies in animals cinogenicity from studies in rats and/ trichloroethylene [TCE], and vinyl and in humans, or limitations in Part 1 · Chapter 1.
