Genome-wide screen of ovary-specific DNA methylation in polycystic ovary syndrome.

Objective: To compare genome-wide DNA methylation profiles in ovary tissue from women with polycystic ovary syndrome (PCOS) and healthy controls.

Design: Case-control study matched for age and body mass index.

Setting: University-affiliated hospital.

Lack of efficacy of Tai Chi in improving quality of life in breast cancer survivors: a systematic review and meta-analysis.

Background: It is controversial whether Tai Chi (TC) benefits breast cancer survivors (BCS) on quality of life (QoL). We therefore undertook a meta-analysis to assess this question.

Materials And Methods: A computerized search through electronic databases was performed to identify relevant randomized controlled trials (RCTs).

Characteristics, sources, and transport of tetrabromobisphenol A and bisphenol A in soils from a typical e-waste recycling area in South China.

We studied the tetrabromobisphenol A (TBBPA) and bisphenol A (BPA) patterns and their sources and transport in different land-use soils from Longtang, South China, a typical electronic waste recycling center. We also studied the reductive debromination of TBBPA in paddy soils. TBBPA and BPA concentrations (on a dry weight basis) were undetected-220 and 0.

Promoter methylation of CYP19A1 gene in Chinese polycystic ovary syndrome patients.

Aims: This study aimed to examine the methylation status of the CYP19A1 promoter region in Chinese polycystic ovary syndrome (PCOS) patients.

Methods: A case-control study was designed that involved 10 PCOS patients and 10 controls. Ovary tissues obtained from 10 women with PCOS and 10 healthy controls were matched for body mass index and age.

Heterogeneous photodegradation of pentachlorophenol and iron cycling with goethite, hematite and oxalate under UVA illumination.

Heterogeneous photodegradation of pentachlorophenol (PCP) in the goethite (alpha-FeOOH) and hematite (alpha-Fe(2)O(3)) systems with oxalate under UVA illumination was investigated. The PCP degradation, dechlorination and detoxification, in terms of Microtox acute toxicity, were all achieved to the higher efficiency in the hematite suspension than in the goethite suspension. The optimal initial concentration of oxalic acid (C(ox)(0)) for the PCP degradation with goethite and hematite under the experimental conditions was found to be 1.

[Clinical study of effect of laparoscopic diagnosis and treatment on pelvic endometriosis-associated infertility].

Objective: To investigate the role of laparoscopy in diagnosis and treatment of infertile women with endometriosis.

Methods: Totally 314 infertile cases were diagnosed as having endometriosis by laparoscopy, and 58, 173, 68 and 15 cases were assigned to stage I, II, III and IV groups respectively according to the revised classification American Fertility Society (r-AFS). Laparoscopic treatment included excision of ovarian endometriosis lesions, lysis of adhesions, endocoagulation of pelvic endometriosis lesions with controlled heating (100 degrees C) and lavaging of the peritoneal cavity.
