Age-specific values of Access anti-Müllerian hormone immunoassay carried out on Japanese patients with infertility: a retrospective large-scale study.

Background: The ovarian reserve in women is known to correlate with anti-Müllerian hormone (AMH) levels, and currently the latest, third-generation, fully-automated AMH immunoassays, such as Access and Cobas, are beginning to be used for measuring AMH levels. However, the age-specific reference values obtained for AMH levels have been based on samples from an American population, measured using first-generation immunoassays. In this study, we attempted to determine the age-specific AMH reference values based on a large set of samples taken from Japanese infertile women measured by Access so that they could be used by infertility centers treating Japanese and those with similar racial and life-style characteristics.

A Novel Treatment for Cervical and Cesarean Section Scar Pregnancies by Transvaginal Injection of Absolute Ethanol to Trophoblasts: Efficacy in 19 Cases.

Study Objective: To evaluate the efficacy of a nonsurgical treatment for cervical pregnancy (CP) and cesarean section scar pregnancy (CSP).

Design: Retrospective clinical study (Canadian Task Force classification III).

Setting: Private assisted reproductive technology practice.

Cytogenetic analysis of the retained products of conception after missed abortion following blastocyst transfer: a retrospective, large-scale, single-centre study.

Cytogenetic analysis of the retained products of conception (POC) is the most effective test for identifying miscarriage causes. However, there has been no large-scale study limited to blastocyst transfer. This study retrospectively reports the findings of 1030 cases in which POC analysis was performed after missed abortion following single blastocyst transfer performed at the Shinbashi Yume Clinic.

Changes in estrone and estradiol levels during follicle development: a retrospective large-scale study.

Background: The improved reagent for measuring estradiol (E2), the ST AIA-PACK iE2 reagent, has a higher specificity for the measurement of E2 levels than the original ST AIA-PACK E2 reagent, because of its lower cross-reactivity with estrone (E1). As we had E2 data obtained with either of the reagents, we analyzed changes in E1 and E2 levels during follicle development.

Methods: The study included 14371 serum hormone measurements from 4412 patients who underwent oocyte retrieval or frozen/thawed embryo transfer in natural cycle in vitro fertilization in Shinbashi YUME clinic, Tokyo, between June 2011 and May 2014.

Efficient subtractive cloning of genes activated by lipopolysaccharide and interferon γ in primary-cultured cortical cells of newborn mice.

Innate immune responses play a central role in neuroprotection and neurotoxicity during inflammatory processes that are triggered by pathogen-associated molecular pattern-exhibiting agents such as bacterial lipopolysaccharide (LPS) and that are modulated by inflammatory cytokines such as interferon γ (IFNγ). Recent findings describing the unexpected complexity of mammalian genomes and transcriptomes have stimulated further identification of novel transcripts involved in specific physiological and pathological processes, such as the neural innate immune response that alters the expression of many genes. We developed a system for efficient subtractive cloning that employs both sense and antisense cRNA drivers, and coupled it with in-house cDNA microarray analysis.

Measurement of retinal thickness from three-dimensional images obtained from C scan images from the optical coherence tomography ophthalmoscope.

Background: One of the unique features of the optical coherence tomography (OCT) ophthalmoscope is that it can record C scan images of the retina. The purpose of this study was to determine the best recording time to measure the retinal thickness with the OCT ophthalmoscope. In addition, the accuracy of the measurements was examined by comparing the values obtained by the OCT ophthalmoscope with those obtained with the Stratus OCT Model 3000 (OCT III) assuming that the OCT III gives an accurate measurement of retinal thickness.

An mRNA amplification procedure with directional cDNA cloning and strand-specific cRNA synthesis for comprehensive gene expression analysis.

We developed an integrated system suitable for comprehensive gene expression studies including construction and analysis of cDNA microarrays starting from a small amount of mRNA. We amplified total mRNA first as cDNA mixtures by polymerase chain reaction and then as strand-specific cRNA mixtures by in vitro transcription. These amplified cDNA and cRNA enabled determination of mRNA levels by hybridization analyses such as Southern, Northern, reverse-Northern macroarray, and cDNA microarray analyses, as well as construction of the cDNA library with a unidirectional cDNA insert.

Comparison of Yatabe-Guilford personality test results in retinitis pigmentosa and glaucoma patients.

Purpose: To determine the psychological state and personality traits of patients with retinitis pigmentosa (RP) or glaucoma so that a closer and better relationship can be developed with the patients.

Methods: The Yatabe-Guilford personality test was administered to 75 RP patients and 42 glaucoma patients. The latter group included 29 cases of primary open-angle glaucoma, 6 of primary angle-closure glaucoma, and 7 of normal-tension glaucoma.

Pattern visual evoked potentials in traumatic optic neuropathy.

To evaluate the characteristics of pattern visual evoked potentials (PVEPs) in traumatic optic neuropathy (TON) compared with optic neuritis (ON), we retrospectively studied 47 patients with TON and 64 patients with unilateral ON. PVEPs elicited by the stimulation with 3 reversals/s were recorded in all patients. A PVEP could be recorded in 29.

Pattern visual evoked cortical potentials predict postoperative visual acuity after cataract surgery in patients with glaucoma.

Visual acuity after cataract surgery in patients with glaucoma cannot be predicted accurately. We studied preoperative recordings of pattern visual evoked cortical potentials (PVECPs) to evaluate postoperative vision in patients with glaucoma and cataract. Fifty patients with glaucoma and no cataract and 31 patients with glaucoma and cataract who underwent phacoemulsification were included in this study.

Learning effect for frequency doubling perimetry in patients with glaucoma.

Purpose: We studied the results obtained by repeated frequency doubling perimetry in patients with glaucoma and demonstrated a learning effect.

Methods: Prospective observational study. Thirty-three patients who had glaucoma and had never experienced frequency doubling perimetry participated in this study.
