Factors influencing the health-related quality of life in Korean menopausal women: a cross-sectional study based on the theory of unpleasant symptoms.

Purpose: Based on the theory of unpleasant symptoms (TOUS), this study aimed to examine the direct effect of antecedent factors on health-related quality of life (HRQoL) and its indirect effect via symptoms in Korean women during the late menopausal transition (MT) and early postmenopause.

Methods: This cross-sectional survey employed a descriptive correlational research design. The respondents were 152 middle-aged women 40 to 60 years with an intermenstrual interval of 60 days or more (late MT) or less than 5 years from the last menstrual period (early postmenopause).

Ring-Shaped Baffle Effect on Separation Performance of Lithium Carbonate Micro Particles in a Centrifugal Classifier.

In this work, a centrifugal classifier for separating lithium carbonate particles, used as a cathode material for lithium-ion batteries, was investigated. This work numerically evaluates the internal flow and particle separation performance of the centrifugal classifier. The complex turbulent flow field in the classifier is key to understanding particle motion.

Unplanned readmission of patients with heart transplantation in 1 year: A retrospective study.

Aim: To investigate readmission rate and its association with patient characteristics to identify key risk factors associated with unplanned readmission in 1 year after heart transplantation.

Background: Unplanned readmission after heart transplantation due to complications affects patients' quality of life and long-term survival rate.

Design: A retrospective cohort study.

A synthetic microbial biosensor for high-throughput screening of lactam biocatalysts.

Biocatalytic cyclization is highly desirable for efficient synthesis of biologically derived chemical substances, such as the commodity chemicals ε-caprolactam and δ-valerolactam. To identify biocatalysts in lactam biosynthesis, we develop a caprolactam-detecting genetic enzyme screening system (CL-GESS). The Alcaligenes faecalis regulatory protein NitR is adopted for the highly specific detection of lactam compounds against lactam biosynthetic intermediates.

Impacts of Psychological Distress, Gender Role Attitude, and Housekeeping Sharing on Quality of Life of Gynecologic Cancer Survivors.

Purpose: To determine impacts of psychological distress, gender role attitude, and housekeeping sharing on quality of life of gynecologic cancer survivors.

Methods: Subjects completed questionnaires consisting of four measurements: FACT-G (ver. 4) for quality of life, anxiety and depression from SCL-90-R for psychological distress, gender role attitude, and housekeeping sharing.

Overexpression of MicA induces production of OmpC-enriched outer membrane vesicles that protect against Salmonella challenge.

Outer membrane vesicles (OMVs) derived from bacteria are promising candidates for subunit vaccines. Stresses that modulate the composition of outer membrane proteins (OMPs) are important for OMV synthesis. Small RNAs (sRNAs) expressed in response to stress regulate OMPs, although the mechanism underlying sRNA-mediated OMV biogenesis and its utility for developing vaccine platforms remains to be elucidated.

Stress-responsively modulated ymdAB-clsC operon plays a role in biofilm formation and apramycin susceptibility in Escherichia coli.

The YmdB protein, an inhibitor of biofilm formation and an inducer of apramycin susceptibility in Escherichia coli (E. coli), is part of a putative operon. However, transcription of this operon and its subsequent effects on biological pathways has not been fully studied.

YmdB-mediated down-regulation of sucA inhibits biofilm formation and induces apramycin susceptibility in Escherichia coli.

Antibiotic resistance associated with biofilm formation is a major concern when treating bacterial infections with drugs. The genes and pathways involved in biofilm formation have been extensively studied and are also involved in antibiotic resistance. Recent studies show that overexpression of Escherichia coli (E.

The effect of lumbar-pelvic alignment and abdominal muscle thickness on primary dysmenorrhea.

[Purpose] The purpose of this study was to identify effects of malalignment of the lumbar pelvis, as a passive element, and the thicknesses of abdominal muscles, as active elements, on primary dysmenorrhea. [Subjects and Methods] The subjects were divided into a primary dysmenorrhea group and normal group according to Visual Analogue Scale, and ultimately there were 28 subjects in the dysmenorrhea group and 22 subjects in the normal group. Alignment of the lumbar pelvis was measured by using a Formetric 4D analysis system, and the thicknesses of abdominal muscles were measured by using ultrasound imaging.

The relationship between pelvic alignment and dysmenorrhea.

[Purpose] The purpose of this study was to investigate the relationship between pelvic alignment and dysmenorrhea in general women. [Subjects and Methods] One hundred two females participated in this study. They were divided into a dysmenorrhea group and a normal group based on the results of a Visual Analogue Scale (VAS) assessment of pain and the Menstrual Distress Questionnaire (MDQ).

[A study of the caregiving burden on grandmothers who raise their grandchildren: a phenomenological research].

Purpose: This qualitative study aimed to identify the common, lived experiences of grandmothers who cared for their grandchildren as the primary caregivers.

Methods: This study was based on the phenomenological method described by Colaizzi (1978).

Results: Seven theme clusters emerged from the data as follows: "grandmother caregivers accept the parenting role of the incessant responsibilities and the distrust of non-kin caregivers.
