Haplotype analysis of the estrogen receptor 1 gene in male genital and reproductive abnormalities 总被引:1,自引:0,他引:1
Watanabe M Yoshida R Ueoka K Aoki K Sasagawa I Hasegawa T Sueoka K Kamatani N Yoshimura Y Ogata T 《Human reproduction (Oxford, England)》2007,22(5):1279-1284
BACKGROUND: We have recently suggested that homozygosity for a specific 'AGATA' haplotype within a approximately 50 kb linkage disequilibrium (LD) block of the gene for estrogen receptor alpha (ESR1) may raise the susceptibility to cryptorchidism by enhancing estrogenic effects of environmental endocrine disruptors (EEDs). METHODS: Haplotype analysis of ESR1 was performed in 328 Japanese subjects, i.e. 70 patients with micropenis (MP), 43 patients with hypospadias (HS), 80 patients with spermatogenic failure (SF) and 135 control males. Genotyping was performed by the 5' nuclease assay. RESULTS: The LD block was identified in each of the patient groups and in the control males. The frequency of homozygotes for the specific 'AGATA' haplotype was markedly higher in the HS patients [P = 0.0000033, odds ratio [OR] = 11.26] and slightly higher in the MP patients (P = 0.034, OR = 3.64) than in the control males, and the 'AGATA' haplotype was strongly associated with HS (P = 0.0000022, OR = 11.26) and weakly associated with MP (P = 0.040, OR = 3.64) in a recessive mode. There was no significant difference between the SF patients and the control males. CONCLUSIONS: Our results support the hypothesis that homozygosity for the specific ESR1 'AGATA' haplotype may increase the susceptibility to the development of male genital abnormalities in response to estrogenic EEDs. 相似文献

Pseudomonas aeruginosa (P. aeruginosa) is a major cause of infectious keratitis, which itself is a major cause of blindness worldwide. We have now evaluated the time-dependent effectiveness of photodynamic antimicrobial chemotherapy (PACT) with the chlorin derivative TONS 504 and a light-emitting diode (LED) on P. aeruginosa in vitro. PACT with TONS 504 (10 mg/L) and irradiation (30 J/m2) by an LED device that delivers light centered on a wavelength of 660 nm was applied to 1?×?106 colony-forming units of P. aeruginosa in liquid medium. The bacteria were then cultured at 37 °C for various times before assay of viability by determination of colony formation on agar plates. The effect of a second irradiation at 3 h after the initial LED exposure was also examined. Bacterial growth was markedly inhibited between 3 and 9 h after PACT with TONS 504, with the maximal effect being apparent at 3 h. Furthermore, a second exposure to LED irradiation at 3 h after the first treatment enhanced the inhibitory effect on bacterial growth. PACT with TONS 504 thus inhibited the growth of P. aeruginosa in a time-dependent manner, and an additional irradiation exposure applied 3 h after the first LED treatment greatly increased the effectiveness of PACT. This antibacterial system thus warrants further evaluation with regard to its potential effectiveness for the treatment of infectious keratitis. 相似文献

Alteration of expression or phosphorylation status of tob, a novel tumor suppressor gene product, is an early event in lung cancer 总被引:3,自引:0,他引:3

Tob is a member of the Tob/BTG family, a novel class of anti-proliferative proteins. To investigate the involvement of tob as a tumor suppressor gene in human lung cancer, we analyzed the expression of tob mRNA and protein in lung cancer tissue and adjacent normal lung tissue. Immunohistochemical analysis using anti-Tob antibody showed decreased expression of Tob in 72% (31/43) of lung cancer tissues. Furthermore, 95% (19/20) of squamous cell carcinoma patients showed an apparent decrease in Tob in cancer tissues, associated with smoking status. The phosphorylated form of Tob, an inactive form of Tob, was detected in 76% (16/21) of cancer tissues of adenocarcinoma patients, but not in normal alveolar epithelial cells. Either a decrease in Tob expression or an accumulation of phosphorylated Tob was observed from early clinical stages, even in bronchial dysplasia, a premalignant lesion of squamous cell carcinoma. The above findings suggest that the disruption of anti-proliferative Tob plays a distinct part in the early stage of lung carcinogenesis. 相似文献

Purpose
To investigate the correlation between the ooplasmic volume and the number of mitochondrial DNA (mtDNA) copies in embryos and how they may affect fecundity.Method
Using real-time PCR, mtDNA quantification was analyzed in unfertilized oocytes and uncleaved embryos. The size of the ovum was also assessed by calculating the ooplasmic volume at the time of granulosa cell removal for IVF or ICSI. Quantification analysis of the mtDNA in blastomeres was performed by real-time PCR at the 7–8 cell stage of the cleaved embryos at 72 h after oocyte retrieval. We calculated the cytoplasmic volume of the blastomeres.Result
Our studies showed a significantly lower mtDNA copy number in unfertilized oocytes and uncleaved embryos in women who were older than 40 years of age (p?<?0.05). The larger ooplasmic volume was also associated with earlier and more rapid cleavage (p?<?0.05). The ooplasmic volume was also significantly larger in the group achieving pregnancy. We found a significant positive correlation between blastomere volume and the number of mtDNA copies (r?=?0.76, p?<?0.01, from Pearson product–moment correlation coefficient).Conclusions
We have shown that blastomere volume is directly proportional to the number of mtDNA copies. Therefore, larger cytoplasmic volume, with earlier cleavage speed, implies more mtDNA copies. Evaluation of mtDNA quantification and the measurement of ooplasmic and blastomere volume may be useful for selection of high quality embryo and pregnancy outcome. 相似文献107.

Gynecology in the office setting is developing worldwide. Clinical guidelines for office gynecology were first published by the Japan Society of Obstetrics and Gynecology and the Japan Association of Obstetricians and Gynecologists in 2011. These guidelines include a total of 72 clinical questions covering four areas (Infectious disease, Malignancies and benign tumors, Endocrinology and infertility, and Healthcare for women). These clinical questions were followed by several answers, backgrounds, explanations and references covering common problems and questions encountered in office gynecology. Each answer with a recommendation level of A, B or C has been prepared based principally on evidence or consensus among Japanese gynecologists.These guidelines would promote a better understanding of the current standard care practices for gynecologic outpatients in Japan. 相似文献

A 50-year-old woman reporting sudden-onset chest pain was diagnosed as having pulmonary infarction associated with Takayasus arteritis. She had experienced moderate malaise and cough for 3 months. Computed tomography (CT) and magnetic resonance imaging (MRI) showed wedge-shaped infiltrative shadows typical of pulmonary infarction in the right lung. Although pulmonary artery involvement in Takayasus arteritis is well documented, most patients show only signs of mild to moderate pulmonary hypertension. Few reports discuss patients with symptoms due to pulmonary infarction as the initial manifestation. Takayasus arteritis should therefore be considered a differential diagnosis in pulmonary infarction. 相似文献

Ono Y, Yoshimura K, Sueoka R, Yamauchi K, Mizushima H, Momose T, Nakamura K, Okonogi K, Asai M. Avoidant personality disorder and taijin kvoufu: Sociocultural implications of the WHO/ ADAMHA International Study of Personality Disorders in Japan. Acta Psychiatr Scand 1996: 93: 172–176. © Munksgaard 1996. This paper discusses the characteristics of avoidant personality disorder in a cultural context based on the Japanese concept of taijin kyoufu as well as that of DSM-III-R and DSM-IV Social phobia. Sixty-six patients were given the International Personality Disorder Examination and questionnaires including the Beck Anxiety Inventory. Among the 23 DSM-III-R personality disorder patients, 8 patients were diagnosed as having avoidant personality disorder. Six of them were suffering from taijin kyoufu symptoms. Among 27 ICD personality disorder patients, 22 patients were diagnosed as having ICD anxious personality disorder. All DSM avoidant patients were included in the ICD anxious group. These findings suggest that patients with avoidant personality disorder have had a long history of difficulties and share common personality problems with a milder form of taijin kyoufu, which is conceptually different from Social phobia. 相似文献
