abstract chromosomal translocations constitute one of the most important, yet uncommon, causes of primary amenorrhea and gonadal dysgenesis. although x-autosome translocations are frequently associated with streak gonads and clinical features of the turner syndrome, the majority of x-autosome carriers may present with a variable phenotype, developmental delay, and recognizable x-linked syndrome...

The intersection of two Steiner triple systems (X,A) and (X,B) is the set A ∩ B. The fine intersection problem for Steiner triple systems is to determine for each v, the set I(v), consisting of all possible pairs (m,n) such that there exist two Steiner triple systems of order v whose intersection I satisfies | ∪A∈I A| = m and |I| = n. We show that for v ≡ 1 or 3 (mod 6), |I(v)| = Θ(v3), where p...

Let 1 ≤ a ≤ b be integers. A triple of the form (x, ax + d, bx + 2d), where x, d are positive integers is called an (a,b)-triple. The degree of regularity of the family of all (a, b)-triples, denoted dor(a, b), is the maximum integer r such that every r-coloring of N admits a monochromatic (a, b)-triple. We settle, in the affirmative, the conjecture that dor(a, b) < ∞ for all (a, b) = (1, 1). W...

background and objectives: the association between metabolic syndrome (mets) and hyperuricemia has been formerly studied mostly in healthy people in western countries. we tried to examine the relationship betweenhyperuricemia and mets in an iranian population undergoing coronary angiography. materials and methods: from march 2008 to september 2008, we studied 465 patients (260 men, 55.9%) unde...

background metabolic syndrome can cause cardiovascular disease and diabetes in the affected subjects. with 20 to 30% prevalence rate among the adult population of most countries, it is considered a pandemic problem. the guidelines currently available on the management of the specific components of metabolic syndrome highlight some lifestyle changes such as enhanced physical activity and weight ...

conclusions marital status may affect mets risk z score differently in both genders. results in comparison to participants who were married, no significant changes in mets risk z score was found in single participants. employed females in the transition to married group had significant increase in mets risk z score than single employed females. no significant changes in mets risk z score were o...

Triple X syndrome (47, XXX) occurs in approximately 1:1,000 female births and has a variable phenotype of physical and psychological features. Prenatal diagnosis rates of 47, XXX are increasing due to non-invasive prenatal genetic testing. Previous studies suggest that prenatal diagnosed females have better neurodevelopmental outcomes. This cross-sectional study describes diagnosis, physical fe...

A case of Ewing sarcoma in a 16-year-old girl with 47 XXXc karyotype is reported.

Facial, oral, and dental findings of an 11-year-old girl with XXX syndrome are reported. Clinical examination reveals midfacial hypoplasia, congenital absence of teeth, and solitary maxillary central incisors both in primary and permanent dentitions.

It is well known that Pythagorean triples can be parametrized by two triples of polynomials with integer coefficients. We show that no single triple of polynomials with integer coefficients in any number of variables is sufficient, but that there exists a parametrization of Pythagorean triples by a single triple of integer-valued polynomials. The second author has recently studied polynomial pa...
