Poly (A+) mRNA was isolated from fetal calf ligamenturn nuchae and used for the construction of cDNA libraries. A fraction highly enriched in elastin mRNA was used to prepare the cDNA probes for screening the libraries. A 2 kb clone, pREl, gave the most positive signal in colony hybridization. It hybridized to a mRNA of the same size as reported for elastin mRNAs from chick and sheep. Hybrid-ar...

Objective To examine the association between increased nuchal translucency thickness and major cardiac defects in chromosomally normal fetuses. Setting Tertiary referral unit for fetal medicine and fetal

Elastic fibers, a major component of the extracellular matrix of the skin, are often exposed to ultraviolet (UV) radiation throughout mammalian life. We report on an in vitro study of the alterations in bovine nuchal ligament elastic fibers resulting from continuous UV-A exposure by the use of transmission electron microscopy (TEM), histology, mass spectrometry, and solid state 13C NMR methodol...

BACKGROUND The prevalence of pterygium colli ("webbed neck") is 75% in patients with Turner syndrome. This congenital deformity manifests as a bilateral cervical skin fold stretching from the mastoid to the acromion. Although the visibility of this skin fold varies among patients, it frequently has negative social effects. The surgical management of this malformation remains challenging as it r...

Nucleotide sequence analysis of cDNA clones for bovine elastin revealed the occurrence of three mRNAs for elastin in fetal calf nuchal ligament, encoding three forms of elastins (a, b, and c, of 747, 733, and 713 amino acid residues, respectively). These forms arise as the result of the presence, at a single position, of 102 additional nucleotides in the mRNA for elastin a and of 60 of these nu...

A new species of the banjo catfish genus Amaralia is described from the Paraná-Paraguay River Basin in central-western Brazil, Paraguay and northern Argentina. Amaralia oviraptor is distinguished from its single and allopatric congener, Amaralia hypsiura, by the greater number of dorsal-fin rays (3 vs. 2); by the absence of lateral contact between middle and posterior nuchal plates (vs. middle ...

conclusions the clinical examination is an important and accurate diagnostic modality for evaluation of traumatic derangement of the knee joint. it is noninvasive, easy, available, and valuable diagnostic modality. the mri is an accurate diagnostic modality. it can be used whenever there is an uncertain indication for arthroscopy. however, costs have to be kept in mind, especially in patients w...

background: to study the outcome of cases with nuchal translucency (nt) ≥ 95th centile in the first trimester of pregnancy. methods: this cross sectional study was performed at iranian fetal medicine foundation (fmf) between january 2009 and december 2011. totally, 186 cases with nt≥ 95th centile who attended for the first trimester screening were studied. all cases with increased nt including ...
