OBJECTIVE The basic protein on Y chromosome, 2 gene (BPY2) is implicated in the spermatogenic process. Three copies (paralogs) of the BPY2 sequence lie in the AZFc region, within huge palindromic repeats consisting of Alu sequences located in 5' flanking regions. Our objective was to screen the single nucleotide variation of BPY2 gene paralogously. (More)
OBJECTIVE To investigate microdeletions and palindrome complexes in the azoospermic factor (AZF) c regions of the Y chromosome, by polymerase chain reaction (PCR) with sequence-tagged site (STS) markers with known physical positions, after verification of the exact physical locations of candidate STSs and exclusion of those that would give ambiguous results(More)
OBJECTIVE To evaluate the relationship between the status of homologous recombination and population-specific alleles in infertile Japanese males with azoospermia factor (AZF)-a deletions and to characterize the clinical features of these patients. DESIGN Retrospective deletion study in infertile Japanese men. SETTING University hospital and(More)
Incorporating sustainability in construction can result in desirable building attributes and project life cycle. The Leadership in Engineering and Environmental Design (LEED®) Rating System helps project teams make the right green building decisions for their projects through a process. However, in current practice, project teams do not have a systematic(More)
