Synthetic polymers, like methacrylate (MA) compounds, have been clinically introduced as inert coatings to locally deliver drugs that inhibit restenosis after stent. The aim of the present study was to evaluate the effects of MA coating alone on vascular smooth muscle cell (VSMC) growth in vitro. Stainless steel stents were coated with MA at the following doses: 0.3, 1.5, and 3 ml. Uncoated/bar...

The aim of the present study was to determine the anti-proliferative and pro-apoptotic effects of dihydromyricetin (DHM) on the AGS human gastric cancer cells and their underlying mechanisms. The effects of DHM on AGS cells were evaluated by using 3-(4, 5-di-methylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT), lactate dehydrogenase, and Annexin V/propidium iodide (PI) double-staining assa...

This study deals with the design and synthesis of a series of novel 4-methoxy-substituted and 5-methyl-substituted (3'S,4'S)-(-)-cis-khellactones. The newly synthesized compounds were characterized by 1H nuclear magnetic resonance (NMR), 13C-NMR, mass spectrometry, and elemental analysis. All the derivatives were subjected to in vitro cytotoxicity screening against HEPG-2 (human liver carcinoma...

The present study aimed to investigate the ability of SS31, a novel mitochondria‑targeted peptide to protect against t‑BHP‑induced mitochondrial dysfunction and apoptosis in 661W cell lines. The 661W cells were treated with various concentrations of SS‑31 and an MTT assay was used to determine cell viability. The expression of nitrotyrosine and 8‑hydroxydeoxyguanosine (8‑OHdG) was detected usin...

Abstract Background Epigenetic dysregulation plays important roles in leukemogenesis and the progression of acute myeloid leukemia (AML). Histone acetyltransferases (HATs) histone deacetylases (HDACs) reciprocally regulate acetylation deacetylation nuclear histones. Aberrant activation HDACs results uncontrolled proliferation blockade differentiation, HDAC inhibition has been investigated as ep...

Abstract Melittin, the most potent pharmacological ingredient of honey bee venom, induces haemolysis, lymphocyte lysis, long-term pain, localised inflammation, and hyperalgesia. In this study, efforts were made to subdue melittin’s ill effects using a chaperone peptide called ‘mini-αA-crystallin’ (MAC) derived from eye lens αA-crystallin. Haemolytic test on human red blood cells, percentage via...

The present study aimed to evaluate the protective effects of emodin on severe acute pancreatitis (SAP)‑associated acute lung injury (ALI), and investigated the possible mechanism involved. SAP was induced in Sprague‑Dawley rats by retrograde infusion of 5% sodium taurocholate (1 ml/kg), after which, rats were divided into various groups and were administered emodin, FK866 [a competitive inhibi...

Objective: In this study, our aim was to extract, and identify and quantify the chemical composition of essential oils of Semenovia suffruticosa grown in Kerman, Iran. Moreover, cytotoxic, antioxidant and antimicrobial activity of the essential oil and methanol extract of aerial parts of S. suffruticosa were reported. Materials and Methods: GC and GC/MS analysis were used for identifying and qu...

The Janus kinase (JAK)1 and JAK2 inhibitor, ruxolitinib, and the active form of vitamin D (calcitriol) were previously reported to possess anticancer effects in breast cancer. The present study investigated the combined effects of ruxolitinib and calcitriol on an estrogen receptor (ER)‑positive, human epidermal growth factor receptor 2 (HER2)‑positive, breast cancer cell line. The ER and HER2‑p...

PURPOSE Diallyl disulfide (DADS) is a major organosulfur compound derived from garlic. It has been reported that DADS is able to inhibit the proliferation of several tumor cells. In this study, the effect of DADS was investigated in terms of the proliferation of AGS, gastric adenocarcinoma cell line at various concentrations. METHODS The viability of cultured cells was determined by 3-(4,5-di...
