Fluorescent fullerene nanoparticle-based lateral flow immunochromatographic assay for rapid quantitative detection of C-reactive protein.

A fluorescent fullerene nanoparticle (NP)-based lateral flow immunochromatographic assay (LFIA) was developed for the rapid and quantitative detection of C-reactive protein (CRP) in serum. The polyclonal CRP-antibody-conjugated fullerene NPs were simply prepared by 1-ethyl-3-(3-dimethyllaminopropyl)-carbodiimide hydrochloride coupling after carboxylation of fluorescent fullerene NPs. By applying the CRP-antibody-conjugated fullerene NPs to a lateral flow test strip, quantitative analysis of CRP in serum was possible at a concentration range of 0.

Mitochondrial DNA copy number in peripheral blood in polycystic ovary syndrome.

Polycystic ovary syndrome (PCOS) is associated with insulin resistance and various metabolic diseases; and recently, elevated oxidative stress has been detected in PCOS. Mitochondria are highly susceptible to oxidative damage; and disordered mitochondrial function at the cellular level can impact whole-body metabolic homeostasis, leading to the hypothesis that abnormalities in markers of mitochondrial metabolism are related to PCOS. We compared mitochondrial DNA (mtDNA) copy number in women with and without PCOS and investigated the independent relationship between mtDNA copy number and PCOS after adjustment for metabolic parameters.

Surgical therapeutic index of tension-free vaginal tape and transobturator tape for stress urinary incontinence.

Background/aims: The aim of this study was to obtain the surgical therapeutic index (STI) of tension-free vaginal tape (TVT) and transobturator tape (TOT) and compare it with the previously obtained result of Burch colposuspension.

Methods: The study population consisted of 121 patients who were diagnosed as having stress urinary incontinence, underwent TVT or TOT between January 1, 2000 and June 30, 2005 and were followed up for at least 1 year. Patients with detrusor overactivity, urinary tract infection, intrinsic sphincter deficiency and pelvic organ prolapse more than stage II according to the POP-Q system were excluded.

Black cohosh and St. John's wort (GYNO-Plus) for climacteric symptoms.

Purpose: This study was conducted to investigate the efficacy of black cohosh (Cimicifuga racemosa) and St. John's wort (Hypericum perforatum) in women with climacteric symptoms, and to assess their effects on vaginal atrophy, hormone levels, and lipid profiles.

Materials And Methods: In this double-blind randomized, placebo-controlled, multicenter study, 89 peri- or postmenopausal women experiencing climacteric symptoms were treated with St.

Roles of sex steroid receptors and cell cycle regulation in pathogenesis of pelvic organ prolapse.

Purpose Of Review: The cause of pelvic organ prolapse is multifactorial and many inciting, promoting and decompensating factors play a role in developing pelvic organ prolapse. Various clinical parameters have been studied quite extensively, but estrogen and collagen metabolism and cell proliferation and apoptosis have not been widely evaluated. This review focuses on assessing the roles of estrogen and its receptor, relationship with collagen metabolism and cell proliferation and cell apoptosis in development and progression of pelvic organ prolapse.

Differences in urodynamic study, perineal sonography and treatment outcome according to urethrovesical junction hypermobility in stress urinary incontinence.

Aims: To evaluate the differences in urodynamic study (UDS) and the perineal ultrasonography parameters between stress urinary incontinence (SUI) patients with or without urethrovesical junction (UVJ) hypermobility. Treatment outcomes following a retropubic urethropexy were also compared.

Methods: The records of 164 SUI patients ( View Article and Find Full Text PDF

The significance of bladder trabeculation in the female lower urinary system: an objective evaluation by urodynamic studies.

This study aimed to investigate the relationship between bladder trabeculation, urinary function, and the stage of pelvic organ prolapse (POP). The medical records of 104 patients with POP who underwent cystoscopies and urodynamic studies were reviewed retrospectively. Age, incidence of detrusor instability, stage and site of POP, and the parameters of urodynamic studies of patients with and without bladder trabeculation were compared.

Roles of estrogen receptor, progesterone receptor, p53 and p21 in pathogenesis of pelvic organ prolapse.

The aim of this study is to compare the levels of estrogen receptor (ER), progesterone receptor (PR), p53 and p21 between pelvic organ prolapse (POP) and control groups in order to evaluate their roles in pathogenesis of POP, and to find out the relationship among these proteins. Through the year of 2002, uterosacral ligaments were obtained from 20 prolapsus and 24 non-prolapsus hysterectomized uteruses. ER, PR, p53, and p21 proteins were extracted by Western blot analysis and relative levels of proteins were compared by Student t-test and Pearson correlation coefficient.

Hysteroscopic endometrial ablation as a treatment for abnormal uterine bleeding in patients with renal transplants.

Study Objective: To assess the effectiveness and safety of hysteroscopic endometrial ablation as a surgical management of abnormal uterine bleeding that develops in patients with renal transplants.

Design: Retrospective study (Canadian Task Force classification II-2).

Setting: Yonsei University Medical College, Severance Hospital.
