Background: The ovulatory LH surge rapidly alters the expression of steroidogenesis-related genes such as steroidogenic acute regulatory protein (StAR) in granulosa cells (GCs) undergoing luteinization. We recently reported that histone modifications contribute to these changes. Histone modifications are regulated by a variety of histone modification enzymes.

We studied the three-dimensional cell-extracellular matrix interactions of endothelial cells that form multicellular structures called sprouts. We analyzed the data collected in-situ from angiogenic sprouting experiments and identified the differentiated interaction behavior exhibited by the tip and stalk cells. Moreover, our analysis of the tip cell lamellipodia revealed the diversity in their interaction behavior under certain conditions (e.

Aims: Pigmented lesions such as of seborrheic keratosis and senile lentigo, which are commonly seen on skin of people>50years of age, are considered unattractive and disfiguring because of their negative psychological impact. Drug therapy using all-trans retinoic acid (ATRA) is an attractive option for self-treatment at home. We have developed an ATRA-loaded microneedle patch (ATRA-MN) and confirmed the pharmacological effects of ATRA-MN application in mice.

The mechanism controlling tissue-specific expression of estrogen receptor 1 (ESR1) is unclear. In other genes, DNA methylation of a region called the tissue-dependent and differentially methylated region (T-DMR) has been associated with tissue-specific gene expression. This study investigated whether human ESR1 has a T-DMR and whether DNA methylation of the T-DMR regulates its expression.

Oxidative stress has a bidirectional role in the development and maturation of zygotes and embryos. Reduction-oxidation reactions and regulatory proteins, such as thioredoxin (TRX) and thioredoxin reductase (TRXR), are intimately involved in the regulation of oxidative stress. The aim of this study was to determine the levels of TRX mRNA and protein in ovarian follicles collected from women undergoing in vitro fertilization (IVF) and to assess these levels relative to follicle size, presence of oocytes, and responsiveness to superovulation.

The dynamics of filopodia interacting with the surrounding extracellular matrix (ECM) play a key role in various cell-ECM interactions, but their mechanisms of interaction with the ECM in 3D environment remain poorly understood. Based on first principles, here we construct an individual-based, force-based computational model integrating four modules of 1) filopodia penetration dynamics; 2) intracellular mechanics of cellular and nuclear membranes, contractile actin stress fibers, and focal adhesion dynamics; 3) structural mechanics of ECM fiber networks; and 4) reaction-diffusion mass transfers of seven biochemical concentrations in related with chemotaxis, proteolysis, haptotaxis, and degradation in ECM to predict dynamic behaviors of filopodia that penetrate into a 3D ECM fiber network. The tip of each filopodium crawls along ECM fibers, tugs the surrounding fibers, and contracts or retracts depending on the strength of the binding and the ECM stiffness and pore size.

Background: Many cross-sectional studies have examined the incidences of herpes zoster (HZ) and postherpetic neuralgia (PHN), but prospective studies in Japanese older adults are lacking. Therefore, we conducted a community-based prospective cohort study to determine the incidence in Japanese adults aged ≥50 years.

Methods: We recruited 12 522 participants from Shozu County, Kagawa Prefecture, between December 2008 and November 2009 and followed participants for 3 years.

A 74-year-old woman presented with dyspnea on exertion and nocturnal cough. Chest computed tomography (CT) revealed scattered bilateral ground-glass opacities without a zonal dominance. Bronchoalveolar lavage elicited increased lymphocytes, but transbronchial lung biopsies were not performed because of hypoxemia during the examination.

Background: Studies in western clinical settings suggest that touch screen computer surveys are an acceptable mode of collecting information about cancer patients' wellbeing

Purpose: We examined the acceptability of a touch screen tablet survey among cancer patients in Japan.

Methods: Eligible patients (n = 262) attending a university hospital radiation therapy (RT) department were invited to complete a touch screen tablet survey about psychosocial communication and care. Survey consent and completion rates, the proportion and characteristics of patients who completed the touch screen survey unassisted, and patient-reported acceptability were assessed.

Background: Despite endometriosis is common estrogen dependent disease afflicting women in reproductive age, the pathogenesis has not been fully elucidated. Retinoic acid has various functions in cells as biologic modulator, and aberrant retinoid metabolism seems to be involved in the lesions of endometriosis. In order to evaluate the potential of all-trans retinoic acid (ATRA) for therapeutic treatment, a transcriptome analysis and estradiol measurements in cultured endometriotic cells and tissues were conducted.

Repeated and dramatic pregnancy-induced uterine enlargement and remodeling throughout reproductive life suggests the existence of uterine smooth muscle stem/progenitor cells. The aim of this study was to isolate and characterize stem/progenitor-like cells from human myometrium through identification of specific surface markers. We here identify CD49f and CD34 as markers to permit selection of the stem/progenitor cell-like population from human myometrium and show that human CD45(-) CD31(-) glycophorin A(-) and CD49f(+) CD34(+) myometrial cells exhibit stem cell-like properties.

Background: The decline of cell-mediated immunity (CMI) is thought to be related to the risk of postherpetic neuralgia (PHN) as well as herpes zoster (HZ). However, the relationship between immunological condition and the incidence of PHN is still unclear.

Objective: We conducted a large-scale prospective cohort study to clarify the relationship between immunological factors for varicella-zoster virus (VZV) and the incidence of PHN.

Objectives: This study investigated the clinical course of myeloperoxidase-antineutrophil cytoplasm autoantibody (MPO-ANCA)-associated vasculitis after starting dialysis.

Methods: A retrospective review was conducted of the clinical charts of dialysis-dependent patients with MPO-ANCA-associated vasculitis who attended one of 8 associated clinics over the past 21 years.

Results: Eighty-nine patients were included in the study; 88 had microscopic polyangiitis (MPA) and 1 had granulomatosis with polyangiitis.

Objectives: The objectives of this study were to examine the whole-serum N-glycan profile of patients with unresectable pancreatic cancer and to evaluate the ability of glycans to predict gemcitabine treatment efficacy and patient survival.

Methods: We collected serum from 52 patients with advanced pancreatic cancer before they began gemcitabine monotherapy. The serum glycan profile was measured through comprehensive quantitative high-throughput glycome analysis and compared with the treatment efficacy and patient survival.

Cardiac tissue engineering aims to recreate functional tissue constructs similar to the structure and function of the native myocardium. To date, in vitro tissue constructs lack the architectural complexity of a vascular network and the precise motor unit control of muscle fibers. Here, we present a method to construct engineered multi-strip cardiac muscle that simulates the bundle-like architecture of the native myocardium.

Canine histiocytic sarcoma (HS) is an aggressive tumor type originating from histiocytic cell lineages. This disease is characterized by poor response to chemotherapy and short survival time. Therefore, it is of critical importance to identify and develop effective antitumor drugs against HS.

In this study, we present a quantitative approach to construct effective 3D muscle tissues through shape optimization and load impedance matching with electrical and optical stimulation. We have constructed long, thin, fascicle-like skeletal muscle tissue and optimized its form factor through mechanical characterization. A new apparatus was designed and built, which allowed us to measure force-displacement characteristics with diverse load stiffnesses.
