Aim： To investigate the associations of autosomal and X-chromosome homologs of the RNA-binding-motif （RNAbinding-motif on the Y chromosome, RBMY） gene with non-obstructive azoospermia （NOA）, as genetic factors for NOA may map to chromosomes other than the Y chromosome. Methods： Genomic DNA was extracted using a salting-out procedure after treatment of peripheral blood leukocytes with proteinase K from Japanese patients with NOA （n = 67） and normal fertile volunteers （n = 105）. The DNA were analyzed for RBMX by expressed sequence tag （EST） deletion and for the like sequence on chromosome 9 （RBMXL9） by microsatellite polymorphism. Results： We examined six ESTs in and around RBMX and found a deletion of SHGC31764 in one patient with NOA and a deletion of DXS7491 in one other patient with NOA. No deletions were detected in control subjects. The association study with nine microsatellite markers near RBMXL9 revealed that D9S319 was less prevalent in patients than in control subjects, whereas D9S1853 was detected more frequently in patients than that in control subjects. Conclusion： We provide evidence that deletions in or around RBMX may be involved in NOA. In addition, analyses of markers in the vicinity of RBMXL9 on chromosome 9 suggest the possibility that variants of this gene may be associated with NOA. Although further studies are necessary, this is the first report of the association between RBMX and RBMXL9 with NOA. （Asian J Andro12006 Mar; 8： 213-218）

Clusters of galaxies are the most massive objects in the Universe and precise knowledge of their mass structure is important to understand the history of structure formation and constrain still unknown types of dark contents of the Universe. X-ray spectroscopy of galaxy clusters provides rich information about the physical state of hot intracluster gas and the underlying potential structure. In this paper, starting from the basic description of clusters under equilibrium conditions, we review properties of clusters revealed primarily through X-ray observations considering their thermal and dynamical evolutions. The future prospects of cluster studies using upcoming X-ray missions are also mentioned.

Careful investigations of live coloration and other characters in the eublepharid gecko Goniurosaurus kuroiwae orientalis from Tonakijima Island, the type locality of the subspecies in the Central Ryukyus, Japan, revealed its slight but consistent external differences from the consubspecific Tokashikijima population, whose phylogenetically divergent status against the former had been strongly suggested in a previous molecular study. A new subspecies, Goniurosaurus kuroiwae sengokui subsp. nov., is thus described for the Tokashikijima population. In life, Goniurosaurus k. sengokui subsp. nov. can be discriminated from G. k. orientalis in showing tint of reddish or pinkish, instead of yellowish, coloration in dorsal body pattern, and also usually darker and more or less reddish, instead of yellowish or grayish, iris in both adults and juveniles. Recalculation of sequence data at hand with relevant Gen Bank data confirmed substantial sequence divergences of G. k. sengokui from all other congeneric taxa of the Ryukyus described so far.

Q-switch for pulsing laser beam and Galvano scanner for rapid scanning laser beam were adapted to manipulate micro solid particles in a water droplet. The trapping of fine particles at micron-sized diameters by a YAG laser system, induced flows, and the induced motion of the particles by laser beam irradiations are discussed. Particle rotations are observed by using anisotropic micro objects, and moreover the rotational rate with clockwise direction is 22 r/min. The fragments of a cover glass were mixed in a water droplet, and their size and shape are uneven. The rotation of that non-spheres without scanning by the Galvano scanner is also observed in water.

Coronary stem implantation has significantly improved percutaneous coronary intervention and enabled the management of early complications of plain balloon angioplasty. However, a new complication has accompanied these improvements： in-stent restenosis （ISR） arising from neointimal hyperplasia. ISR after coronary angioplasty is currently one of the main limitations of this method, leading to the recurrence of exertional angina pectoris or acute coronary syndromes. The clinical incidence of ISR after bare-metal stent （BMS） implantation is approximately 20%35%. The use of drug-eluting stents （DES） has led to a further decrease in the occurrence of ISR to 5%-10%. Evidence resulting from controlled clinical studies suggests that DES and drug-eluting balloon catheters （DEB） provide the best clinical and angiographic results in the treatment of ISR. We undertook a systematic review of the pathophysiology, diagnostics and treatment options for BMS- and DES-ISR. We discuss recent randomised studies, comparing different DES or DEB used for BMS or DES-ISR treatment, as well as the use of new biovascular scafolds and the topic of scafold restenosis.
