An automated biopsy gun with an 18-gauge needle was used for biopsies under US guidance.

Intralymphatic Histiocytosis Associated with Osteoarthritis: A Case Report.

Intralymphatic histiocytosis (ILH) is a rare cutaneous condition with uncertain pathogenesis. It is characterized by dilated lymphatic vessels that contain histiocytes within their lumina. Although the etiology of ILH remains unknown, it has been associated with various inflammatory and neoplastic diseases, such as rheumatoid arthritis (RA), reaction to metal joint implants and Merkel cell carcinoma, breast cancer and colon cancer.

Constraining the effectiveness of inherent tracers of captured CO for tracing CO leakage: Demonstration in a controlled release site.

Geological storage of carbon dioxide (CO) is an integral component of cost-effective greenhouse gas emissions reduction scenarios. However, a robust monitoring regime is necessary for public and regulatory assurance that any leakage from a storage site can be detected. Here, we present the results from a controlled CO release experiment undertaken at the K-COSEM test site (South Korea) with the aim of demonstrating the effectiveness of the inherent tracer fingerprints (noble gases, δC) in monitoring CO leakage.

Diacerein, an inhibitor of IL-1β downstream mediated apoptosis, improves radioimmunotherapy in a mouse model of Burkitt's lymphoma.

Lymphoma has the characteristics of a solid tumor. Penetration of monoclonal antibodies is limited in solid tumors during radioimmunotherapy (RIT). Here, we first investigated the use of diacerein (DIA) as a combination drug to improve the penetration and therapeutic efficacy of I-rituximab (RTX) using the Burkitt's lymphoma mouse model.

Shift of nitrate sources in groundwater due to intensive livestock farming on Jeju Island, South Korea: With emphasis on legacy effects on water management.

Time lags between anthropogenic nitrogen inputs and their impacts to nitrate levels cause a misunderstanding for sources and subsequently misguide the groundwater management.We investigated the hydrochemical data of groundwater samples (n = 172 from 49 wells) with chlorofluorocarbons (CFCs)-based groundwater age dating and stable N (δN) and O isotopes (δO) of nitrate to assess the legacy effect of livestock farming to groundwater in an agricultural area where intensive livestock farming started in the 1970s and illegal dumping of manure wastewater in a lava cave was revealed in 2015. Approximately 90% of the groundwater samples had nitrate concentrations exceeding the natural threshold (5.

New Surgical Approach for Secondary Intraocular Lens Implantation Using an Artificial Bag with Optic Capture in Patients with Intraocular Lens Dislocation.

Purpose: We present a newly developed approach to secondary intraocular lens (IOL) implantation, which uses an artificial bag with optic capture (i.e., ABC technique) in patients with IOL dislocation.

Imaging Features of Various Benign and Malignant Tumors and Tumorlike Conditions of the Pleura: A Pictorial Review.

Pleural masses may be caused by various conditions, including benign and malignant neoplasms and non-neoplastic tumorlike conditions. Primary pleural neoplasms include solitary fibrous tumor, malignant mesothelioma, and primary pleural non-Hodgkin's lymphoma. Metastatic disease is the most common neoplasm of the pleura and may uncommonly occur in patients with hematologic malignancy, including lymphoma, leukemia, and multiple myeloma.

Clinicoprognostic characteristics of cutaneous metastatic melanoma: a retrospective comparative study between acral and nonacral melanoma.

Background: Although cutaneous melanoma has been widely evaluated, data elucidating the clinical features and prognostic factors of cutaneous metastatic melanoma are limited.

Objective: To determine and compare the clinicoprognostic features of cutaneous metastasis in acral and nonacral melanoma.

Methods: The Asan Medical Center database was reviewed for cases of cutaneous metastatic melanoma that had been confirmed by skin biopsy between January 1996 and December 2017.

Effect of Nd:YAG Laser Capsulotomy on Anterior Segment Parameters in Patients with Posterior Capsular Opacification after Phacovitrectomy.

Purpose: To compare changes in anterior segment parameters after Nd:YAG laser capsulotomy in eyes that underwent either combined phacovitrectomy or cataract surgery.

Methods: This retrospective study enrolled 37 eyes of 35 patients with posterior capsular opacification treated with combined phacovitrectomy (group A), and 35 eyes of 32 patients with posterior capsular opacification treated with cataract surgery (group B). Anterior segment parameters, including anterior chamber depth (ACD), anterior chamber angle, and anterior chamber volume, were measured by a Pentacam before Nd:YAG laser capsulotomy and 1 hour, 1 day, 1 week, 1 month, and 3 months after this treatment.

The Effect of a Parental Visitation Program on Emergence Delirium Among Postoperative Children in the PACU.

Purpose: The purpose of this study was to examine the effects of parental presence on the incidence of emergence delirium (ED) of children in the postanesthesia care unit (PACU).

Design: A quasi-experimental pretest and post-test study with nonequivalent and nonsynchronized control groups.

Methods: About 93 children aged 3 to 6 years undergoing general anesthesia for tonsillectomy were divided into two groups: parental presence and absence.

Epidermal Growth Factor Relieves Inflammatory Signals in -Treated Human Epidermal Keratinocytes and Atopic Dermatitis-Like Skin Lesions in Nc/Nga Mice.

Atopic dermatitis (AD) is a chronic inflammatory skin disease with a defective immunologic barrier, which is aggravated by . Epidermal growth factor (EGF) suppresses inflammation and EGF receptor inhibitors increased colonization. Thus, we investigated the potential roles of EGF in AD, which is often aggravated by .

Antioxidative properties of ginsenoside Ro against UV-B-induced oxidative stress in human dermal fibroblasts.

Ginsenoside Ro (Ro), an oleanolic acid-type ginsenoside, exhibited suppressive activities on reactive oxygen species (ROS) and matrix metalloproteinase-2 (MMP-2) elevation in UV-B-irradiated fibroblasts. Ro could overcome the reduction of the total glutathione (GSH) contents in UV-B-irradiated fibroblasts. Ro could not interfere with cell viabilities in UV-B-irradiated fibroblasts.
