در تحقیق حاضر با هدف حذف آلاینده های پاراتولوئن سولفونیک اسید (p-tsa) و پاراتولوئیک اسید (p-ta) از محیط آبی، در ابتدا جاذب پلی استایرن توسط سه گروه عاملی مختلف (مونواتانول آمین، دی اتانول آمین و تری اتانول آمین) عامل دار شد. پس از آن مناسبترین شرایط برای تولید جاذب از نظر نوع و میزان گروه های عاملی تعیین گردید. بر این اساس، عامل دار کردن جاذب پلیمری توسط دی اتانول آمین و با بیشینه ی دانسیته ی گ...
BACKGROUND The rate of total shoulder arthroplasty (TSA) is rising, which has an impact on health care expenditure. One avenue to mitigate cost is outpatient TSA. There are currently no published reports of this practice. In this study, we determine the 30-day adverse event and readmission rates after outpatient TSA and compare these rates with inpatient TSA. METHODS A retrospective cohort st...
Recently we have demonstrated the possibility to replace histones with protamine, through the heterologous expression of human protamine 1 (hPrm1) gene in sheep fibroblasts. Here we have optimized protaminization of somatic nucleus by adjusting the best concentration and exposure time to trichostatin A (TSA) in serum-starved fibroblasts (nuclear quiescence), before expressing Prm1 gene. To stop...
In this study, we investigated the effect of trichostatin A (TSA) on the gastric cancer cell line BGC-823. The effect of TSA on growth inhibition and apoptosis of BGC-823 cells was examined. The gene expression profile was determined by microarray. Western blotting was used to study the levels of acetylated histone H4 and Glycoprotein non-metastatic melanoma protein B (GPNMB) proteins. GPNMB ge...
BACKGROUND Group 2 innate lymphoid cells (ILC2) are an important source of the type 2 cytokines interleukin (IL)-5 and IL-13 that are critical to the allergic airway phenotype. Previous studies reported that histone deacetylase (HDAC) inhibition by trichostatin A (TSA) downregulated adaptive allergic immune responses; however, the effect of HDAC inhibition on the early innate allergic immune re...
This study described surgical treatment patterns for proximal humerus fractures among elderly patients, focusing on reverse total shoulder arthroplasty (TSA), and evaluated how the type of fixation affects inpatient factors (cost, length of stay), transfusion rates, and patient disposition (home vs skilled nursing facility). With Nationwide Inpatient Sample data from 2011 to 2013, the authors i...
BACKGROUND/AIMS Serrated polyps have emerged as important evidence supporting the serrated polyp-neoplasia pathway in colorectal carcinogenesis, an alternate to the classical adenoma-carcinoma sequence. However, there is confusion over the diagnostic criteria for serrated polyps including traditional serrated adenoma (TSA) and sessile serrated adenoma (SSA). In addition, clinical and pathologic...
Background: Hepatocellular carcinoma (HCC), primary liver cancer, is a major health problem and the third most common cause of cancer-related deaths worldwide. Epigenetic modulations are essential for the maintenance of gene expression patterns in mammals. Disruption of these processes can lead to silenced gene and malignant cellular transformation. The current study was designed to compare the...
Long non-coding RNAs (lncRNAs) have been implicated in liver carcinogenesis. We previously showed that the induction of lncRNA-uc002mbe.2 is positively associated with the apoptotic effect of trichostatin A (TSA) in hepatocellular carcinoma (HCC) cells. The current study further analyzed the role of uc002mbe.2 in TSA-induced liver cancer cell death. The level of uc002mbe.2 was markedly increase...
