competition [37] is suggested to study the principles of competition in their most generic form [8–10]. Consider a complex competitive system, which has a large number of autonomous elements engaged in competition with each other. The evolution of a competitive system involves a process of determining a winner and a loser for competition between any two elements of the system. The non-conservat...

Chromosome 15q24 microdeletion syndrome is a recently described rare microdeletion syndrome that has been reported in 19 individuals. It is characterized by growth retardation, intellectual disability, and distinct facial features including long face with high anterior hairline, hypertelorism, epicanthal folds, downslanting palpebral fissures, sparse and broad medial eyebrows, broad and/or depr...

The widespread use of whole genome analysis based on array comparative genomic hybridization in diagnostics and research has led to a continuously growing number of microdeletion and microduplication syndromes (MMSs) connected to certain phenotypes. These MMSs also include increasing instances in which the critical region can be reciprocally deleted or duplicated. This review catalogues the cur...

Background The human Y chromosome is essential for human sex determination and male germ cell development and maintenance. In 1996, Vogt et al. identified three recurrently deleted regions in Yq11 termed the azoospermia factor (AZF). The AZF region is subdivided into three non-overlapping sub-regions called AZFa, AZFb and AZFc and microdeletion in these regions is the most important etiology of...

background: infertility is a health problem which affects about 10-20% of married couples. male factor infertility is involved approximately 50% of infertile couples. most of male infertility is regarding to deletions in the male-specific region of the y chromosome. objective: in this study, the occurrence of deletions in the azf region and association between infertility and paternal age were ...

A 15-year-old girl was investigated because of ambiguous genitalia. Her chromosome studies showed a 45, X/45, Xdic(Yq) mosaicism. The identity of the dicentric Y chromosome was demonstrated by its typical fluorescent banding patterns. Histological evidence of mixed gonadal dysgenesis with intragonadal tumour was observed, confirming the occurrence of gonadoblastoma associated with mosaicism in ...

Although the presence of a Y specific growth gene(s) (Y growth gene(s) on Yq has widely been accepted, it remains unknown how this gene promotes stature. In this report, we discuss the growth pattern in normal boys and girls and in patients with growth disorders informative for the Y growth gene(s). The results suggest that the Y growth gene(s) augments statural growth by controlling the sex st...

Planar functions over finite fields give rise to finite projective planes and other combinatorial objects. They were originally defined only in odd characteristic, but recently Zhou introduced a definition in even characteristic which yields similar applications. In this paper we show that certain functions over F2r are planar, which proves a conjecture of Schmidt and Zhou. The key to our proof...
