Effects of exotic Spartina alterniflora invasion on benthic environments in the Yellow Sea.

For four decades, cordgrass (Spartina alterniflora) has invaded salt marshes in the Yellow Sea, altering physical, biogeochemical, and biological processes. Here, we investigated the ecological effects of S. alterniflora invasion on benthic environments compared to native halophytes.

Ecological interruption on food web dynamics by eutrophic water discharge from the world's longest dike at Saemangeum, Yellow Sea.

The man-made sea dike has disrupted the natural link between riverine and marine ecosystems and caused eutrophication within the aquatic ecosystem. The eutrophic water discharge has also raised concerns. As a representative tidal flat with the longest dike in the world, Saemangeum has experienced the problem of eutrophication.

Food web dynamics in the mangrove ecosystem of the Pearl River Estuary surrounded by megacities.

Global recognition that mangroves support coastal ecosystem services has increased; however, studies on trophic dynamics in mangrove ecosystems remain limited. We seasonally analysed the δC and δN of 34 consumers and 5 diets to elucidate the food web dynamics in the Pearl River Estuary (PRE). Fish had a large niche space during the monsoon summer, reflecting increased trophic roles.

Risk of developing major depressive disorder in polycystic ovary syndrome: a retrospective cohort study.

This study aimed to investigate the risk of developing major depressive disorder (MDD) in women with polycystic ovary syndrome (PCOS). As a population-based retrospective cohort study based on the Korean National Health Insurance Claims Database and National Health Information Database, newly diagnosed 26,251 women with PCOS with age matched 131,480 women without PCOS from 2007 to 2010 were followed longitudinally and the subsequent occurrence of newly onset MDD was evaluated. The risk of developing MDD in women with PCOS after adjusting for various confounding variables was higher compared to women without PCOS (hazard ratio [HR]1.

Stable isotope signatures reveal the significant contributions of microphytobenthos and saltmarsh-driven nutrition in the intertidal benthic food webs.

A tidal saltmarsh supporting marine ecosystem services becomes more recognized, but an understanding of its trophic dynamics is far limited. We investigated the benthic food-web dynamics in Ganghwa tidal flat, a representative tidal saltmarsh of South Korea. The stable carbon and nitrogen isotope ratio values were analyzed for the sixteen species of macrobenthos and their potential food sources such as microphytobenthos (MPB) and various organic matters.

Effects of Korean Red Ginseng ( C.A. Meyer) on Menopausal Symptoms in Premenopausal Women After Gynecologic Cancer Surgery: A Double-Blind, Randomized Controlled Trial.

Korean red ginseng (KRG) has been widely used as an alternative medicine to relieve menopausal symptoms. However, there is still a lack of clinical studies showing the effects of KRG on menopausal symptoms after gynecologic cancer surgery. Therefore, the authors investigated the effects of KRG on surgical menopause symptoms in premenopausal women with gynecologic cancer.

The role of port site local anesthetic injection in laparoendoscopic single site surgery: a prospective randomized study.

Objective: To investigate the role of port-site bupivacaine hydrochloride injection in laparoendoscopic single-site surgery (LESS) as a means of postoperative umbilical pain alleviation.

Methods: A total of 200 consecutive patients who underwent LESS from October 2018 to February 2019 were included in this randomized prospective case control study. The patients were alternatively assigned to either the study group (0.

Prognostic significance of supradiaphragmatic lymph node metastasis detected by F-FDG PET/CT in advanced epithelial ovarian cancer.

Background: Supradiaphragmatic lymph node metastases (SdLNM) are frequently identified using F-FDG positron emission tomography/computed tomography (PET/CT) in advanced epithelial ovarian cancers (AEOC). This study aimed to determine the prognostic significance of SdLNM detected by PET/CT in patients with AEOC.

Methods: Medical records of patients diagnosed with AEOC were retrospectively registered from January 2009 to July 2015.

Demographic characteristics of labial adhesion in South Korea: a population-based study from 2010 to 2014.

Objective: To investigate the demographic features of labial adhesion (LA) in South Korea.

Design: A population-based nationwide study.

Setting: Census population of South Korea.

Comparison of Clinical Features and Outcomes in Epithelial Ovarian Cancer according to Tumorigenicity in Patient-Derived Xenograft Models.

Purpose: Although the use of xenograft models is increasing, few studies have compared the clinical features or outcomes of epithelial ovarian cancer (EOC) patients according to the tumorigenicity of engrafted specimens. The purpose of this study was to evaluate whether tumorigenicity was associated with the clinical features and outcomes of EOC patients.

Materials And Methods: Eighty-eight EOC patients who underwent primary or interval debulking surgery from June 2014 to December 2015 were included.

Sentinel lymph node mapping with indocyanine green in vaginal cancer.

Objective: Sentinel lymph node (SLN) mapping is being adapted to gynecologic cancer. Higher SLN mapping rates were reported with indocyanine green (ICG) compared to other dyes. The aim of this film is to share our experience of SLN mapping with ICG in vaginal cancer.

Surgical technique for single-port laparoscopy in huge ovarian tumors: SW Kim's technique and comparison to laparotomy.

Objective: This study aimed to introduce a method to remove huge ovarian tumors (≥15 cm) intact with single-port laparoscopic surgery (SPLS) using SW Kim's technique and to compare the surgical outcomes with those of laparotomy.

Methods: Medical records were retrospectively reviewed for patients who underwent either SPLS (n=21) with SW Kim's technique using a specially designed 30×30-cm-sized 3XL LapBag or laparotomy (n=22) for a huge ovarian tumor from December 2008 to May 2016. Perioperative surgical outcomes were compared.

Delayed hemorrhage effect of local anesthesia with epinephrine in the loop electrosurgical excisional procedure.

Objective: The aim of this study was to investigate factors preventing delayed hemorrhage after the loop electrosurgical excisional procedure (LEEP).

Methods: Medical records of patients who underwent LEEP at one university affiliated hospital from October 2013 to January 2015 were reviewed. Patients with or without delayed hemorrhage were classified.

A comparison of clinical and surgical outcomes between laparo-endoscopic single-site surgery and traditional multiport laparoscopic surgery for adnexal tumors.

Objective: The purpose of this study was to compare clinical and surgical outcomes between laparo-endoscopic single-site (LESS) surgery and traditional multiport laparoscopic (TML) surgery for treatment of adnexal tumors.

Methods: Medical records were reviewed for patients undergoing surgery for benign adnexal tumors between January 2008 and April 2012 at our institution. All procedures were performed by the same surgeon.
