PPI use may increase the risk of hypomagnesemia. However, significant heterogeneity among the included studies prevented us from reaching a definitive conclusion.

BACKGROUND AND STUDY AIMS: Intestinal Behçet's disease and Crohn's disease are chronic inflammatory bowel diseases that are difficult to distinguish from each other. We investigated their colonoscopic features and identified simple and valuable strategies for differential diagnosis. PATIENTS AND METHODS: Between 1995 and 2006, 250 consecutive patients with ulcers on colonoscopy (115 Behçet's, 135 Crohn's cases) were reviewed. All patients with Behçet's fulfilled the criteria of the International

이 논문의 목적은 다문화주의와 관련해 미디어/문화연구의 분야에서 이루어진 기존 논의들을 비판적으로 검토하고 앞으로의 연구 방향성을 모색해 보려는 데 있다. 이를 위해 우리는 다음과 같은 세 가지 주제를 중점적으로 다루고자 한다. 먼저 서구에서 1970년대 이후부터 본격적으로 일어난 다문화주의 논쟁을 개관하고 국내에서 다문화주의가 부상하게 된 과정을 비판적으로 검토한다. 이와 더불어 국내에서는 다문화주의와 관련해 어떠한 연구들이 진행되어 왔고 거기에는 또 어떠한 특징이 있는지 미디어/문화연구 분야의 작업들을 중심으로 살펴보고자 한다. 이러한 논의를 바탕으로 다문화주의와 관련해 미디어/문화연구 분야에서는 현재 어떠한 연구가 시급하게 요청되는지, 우리의 사회문화적 맥락 속에서 장기적으로는 어떠한 연구가 필요한지 그 방향성을 가늠해보고자 한다.

3D printing is a method of rapid prototyping and manufacturing in which materials are deposited onto one another in layers to produce a three-dimensional object. Although 3D printing was developed in the 1980s and the technology has found widespread industrial applications for production from automotive parts to machine tools, its application in pharmaceutical area is still limited. However, the potential of 3D printing in the pharmaceutical industry is now being recognized. The ability of 3D pr

Three-dimensional (3D) printing has been recently employed in the design and formulation of various dosage forms with the aim of on-demand manufacturing and personalized medicine. In this study, we formulated a floating sustained release system using fused deposition modeling (FDM). Filaments were prepared using hypromellose acetate succinate (HPMCAS), polyethylene glycol (PEG 400) and pregabalin as the active ingredient. Cylindrical tablets with infill percentages of 25%, 50% and 75% were desig

BACKGROUND: Despite recent advances in studies on the gastric microbiome, the role of the non-Helicobacter pylori gastric microbiome in gastric carcinogenesis remains unclear. We evaluated the characteristics of the gastric microbiome and metagenomic functions in patients with IM. METHODS: Participants were classified into six groups according to disease status (chronic superficial gastritis [CSG], intestinal metaplasia [IM], and cancer) and H. pylori- infection status (H. pylori-positive and H.

HOTAIR, a long non-coding RNA (lncRNA), plays a crucial role in tumor initiation and metastasis by interacting with the PRC2 complex and the modulation of its target genes. The role of HOTAIR in gastrointestinal stromal tumors (GISTs) is remains unclear. Herein we investigate the mechanism of HOTAIR in the genesis and promotion of GISTs. The expression of HOTAIR was found to be higher in surgically resected high-risk GISTs than that in low- and intermediate-risk GISTs. Using GIST-T1 and GIST882

BACKGROUND: Gastric cancer is the second leading cause of cancer globally, and the mechanism of its pathogenesis is still largely unknown. Recently, non-coding RNAs have been recognized to promote metastasis in various cancers, including gastric cancer. METHODS: We found that metastasis associated lung adenocarcinoma transcript-1 (MALAT1) is upregulated in gastric cancer tissue compared to adjacent normal tissue, as determined by microarray and subsequent qRT-PCR, then investigated the impact of
