Feasibility and Surgical Outcomes of Hybrid Robotic Single-Site Hysterectomy Compared with Single-Port Access Total Laparoscopic Hysterectomy.

We compared surgical outcomes between single-port access total laparoscopic hysterectomy (SPA-TLH) and hybrid robotic single-site hysterectomy (RSSH), a new technique of combining the benefits of SPA-TLH with RSSH in this study. A total of 64 patients were retrospectively analyzed. They underwent either hybrid RSSH or SPA-TLH for benign gynecologic disease between December 2018 and August 2021.

Comparison of Surgical Outcomes of Hysterectomy by Vaginal Natural Orifice Transluminal Endoscopic Surgery (vNOTES) versus Single-Port Access (SPA) Surgery.

Single-port access (SPA) laparoscopic surgery and vaginal natural orifice transluminal endoscopic surgery (vNOTES) have many advantages. The objective of the present study is to compare patient characteristics, operative details, and postoperative outcomes between the two surgical methods. Patients who were planned to undergo vNOTES or SPA laparoscopic surgery between April 2020 and June 2021 were prospectively enrolled.

This study aims to find out how COVID-19-related news was handled in the domestic media to seek ways to minimize the pandemic.

Effects of mesenchymal stem cell therapy on alopecia areata in cellular and hair follicle organ culture models.

Mesenchymal stem cell therapy (MSCT) has been suggested as a new therapeutic strategy for immunological disorders. There have been only a few attempts to treat alopecia areata (AA) with MSCT. MSCT efficacy and mechanism of action in treating AA are not known.

Prostaglandin D2-Mediated DP2 and AKT Signal Regulate the Activation of Androgen Receptors in Human Dermal Papilla Cells.

Prostaglandin D2 (PGD2) and prostaglandin D2 receptor 2 (DP2) is known to be an important factor in androgenetic alopecia (AGA). However, the effect of PGD2 in human dermal papilla cells (hDPCs) is not fully understood. The function of PGD2-induced expression of the androgen receptor (AR), DP2, and AKT (protein kinase B) signal were examined by using real time-PCR (qRT-PCR), western blot analysis, immunocytochemistry (ICC), and siRNA transfection system.

Determination of N-nitrosodiethanolamine, NDELA in cosmetic ingredients and products by mixed mode solid phase extraction and UPLC-tandem mass spectrometry with porous graphitic carbon column through systemic sample pre-cleanup procedure.

A rapid, sensitive, accurate and specific ultra-performance liquid chromatography coupled to tandem mass spectrometry (UPLC-MS/MS) method for the detection of N-nitrosodiethanolamine (NDELA), a highly toxic contaminant in cosmetic raw materials and products was developed and validated. Systematized sample preparation steps were developed according to product types. Various SPE cartridges and columns were examined to establish the condition of SPE and chromatographic separation for NDELA.

A study on the correlation between the grain size and the conversion efficiency of Mc-Si solar cells.

For grain size estimation, a prototype system was developed by integrating a vision-acquiring hardware and a vision-assistant-processing module based on the platform software package of LabVIEW, to systematically estimate the average grain size of solar-grade multicrystalline (mc)-Si wafers. Three groups of 156 x 156 mm mc-Si wafers were selected to produce the average grain sizes of 3.4 mm (Group 1), 3.

Transgenic Expression of MsHsp23 Confers Enhanced Tolerance to Abiotic Stresses in Tall Fescue.

Tall fescue (Festuca arundinacea Schreb.) is an important cool season forage plant that is not well suited to extreme heat, salts, or heavy metals. To develop transgenic tall fescue plants with enhanced tolerance to abiotic stress, we introduced an alfalfa Hsp23 gene expression vector construct through Agrobacterium-mediated transformation.

Novel augmented ADIM training using ultrasound imaging and electromyography in adults with core instability.

Objective: To determine the effect of novel augmented abdominal drawing-in maneuver (ADIM) training using rehabilitative ultrasound imaging (RUSI) and electromyography (EMG) in adults with core instability.

Methods: A convenience sample of 20 young adults with core instability (female =4; mean age ± standard deviation=24.4 ± 2.

Occurrence of norovirus and other enteric viruses in untreated groundwaters of Korea.

A total of 39 water samples from 23 different groundwater wells in Korea were collected and analyzed in order to monitor the occurrence of norovirus (NoV) and other indicator microbes as the first part of a national survey of groundwater. More than 500 L of untreated groundwater were filtered through 1MDS filters. Following elution and concentration by organic flocculation, PCR and sequence analysis were employed to detect and identify NoV, enterovirus, rotavirus, hepatitis A virus and adenovirus (Adv).

Use of virtual reality to enhance balance and ambulation in chronic stroke: a double-blind, randomized controlled study.

Objective: To examine an additive effect of virtual reality on balance and gait function in patients with chronic hemiparetic stroke.

Design: Twenty-four adults with hemiparetic stroke were randomly assigned to either an experimental group (n = 12) or a control group. Both groups underwent conventional physical therapy, 40 mins a day, 4 days a week for 4 wks.

Synthesis of 10-substituted triazolyl artemisinins possessing anticancer activity via Huisgen 1,3-dipolar cylcoaddition.

Most of the 10-substituted triazolylartemisinin synthesized via the Huisgen 1,3-dipolar cylcoaddition of diastereomeric 10-azidoartemisinin (5, 6, and 7) with various alkynes (a-h) exhibit strong growth inhibition activity, even at sub-micromolar concentrations, against various cancer cell lines such as DLD-1, U-87, Hela, SiHa, A172, and B16. In particular, 10b and 10f showed a highly strong cytotoxicity.

AIP1, a water-soluble fraction from Artemisia iwayomogi, suppresses thymocyte apoptosis in vitro and down-regulates the expression of Fas gene.

The AIP1 fraction, a small water-soluble fraction purified from Artemisia iwayomogi, was shown to increase antibody production and suppress transplanted tumor cell growth in mice. In order to understand its immuno-modulating activity, we have examined the effect of the AIP1 on mouse thymocytes in vitro. Treatment of mouse thymocytes in culture with the fraction resulted in the suppression of the cell death and the extension of the cell survival.

A carbohydrate fraction, AIP1, from Artemisia iwayomogi down-regulates Fas gene expression and suppresses apoptotic death of the thymocytes induced by 2,3,7,8-tectrachlorodibenzo-p-dioxin.

Apoptotic death of mouse thymocytes in vitro, as induced by 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), involves the up-regulation of Fas gene expression, while a carbohydrate fraction, AIP1, from Artemisia iwayomogi suppresses the death of thymocytes in culture along with the down-regulation of Fas gene expression. We have now investigated whether the AIP1 fraction modulates TCDD-induced thymocyte death. When treated with TCDD and AIP1 fraction together, the thymocytes do not show apoptosis induced by the TCDD treatment.

An oligosaccharide fraction from Korean mugwort herb suppresses death of the mouse thymocytes in culture by down-regulating the Fas death receptor gene.

Korean mugwort herb is a preparation of dried leaves from Artemisia species and has been used as a traditional medicine in Asia. An oligosaccharide fraction, AVF3, purified from the preparation promoted survival of the mouse thymocytes in culture. A mouse gene array study suggests that the AVF3 may modulate Fas/FasL dependent apoptotic cell death and thus has influence on the survival of the thymocytes in culture.

The polysaccharide fraction AIP1 from Artemisia iwayomogi suppresses apoptotic death of the mouse spleen cells in culture.

A polysaccharide fraction, AIP1, purified from Artemisia iwayomogi was shown to have immunomodulating and anti-tumor activities in mice. In order to determine how the AIP1 fraction exhibits the immunomodulating activity, the effect of the fraction on the apoptosis of mouse spleen cells was investigated. Treatment of the mouse spleen cells with the AIP1 fraction resulted in the suppression of apoptotic death and an extension of cell survival in culture, indicating that the fraction might modulate the death of spleen cells.
