BACKGROUND Gastric cancer is one of the most common malignant diseases worldwide. Emerging evidence has shown that microRNAs (miRNAs) are associated with tumor development and progression. Our previous studies have revealed that H. pylori infection was able to induce the altered expression of miR-30b in gastric epithelial cells. However, little is known about the potential role of miR-30b in ga...

در این پژوهش آلیاژهای امتزاج ناپذیر پلی آمید 6 (pa6) و کوپلیمر اتیلن-1-بوتن مالئیکه (eb-g-mah) که یک پلی الفین الاستومر محسوب می شود به روش اختلاط مذاب تهیه شده و توزیع ذرات نانو رس اصلاح شده با مواد آلی در بین فازهای این آلیاژ بررسی شده است. سه نوع نانو رس مختلف با نام های تجاری cloisite 20a، cloisite 15a و cloisite 30b که دارای مولکول های آلی اصلاح کننده متفاوتی هستند و در نتیجه قطبیت متفاوتی...

BACKGROUND Vascular calcification resembles bone formation and involves vascular smooth muscle cell (SMC) transition to an osteoblast-like phenotype to express Runx2, a master osteoblast transcription factor. One possible mechanism by which Runx2 protein expression is induced is downregulation of inhibitory microRNAs (miR). METHODS AND RESULTS Human coronary artery SMCs (CASMCs) treated with ...

کارایی ضدباکتریایی فیلم‌های نانوکامپوزیتی پلی‌اتیلن با دانسیته پائین حاوی نانوذرات خاک رس اصلاح‌شده با نقره در مقابل باکتری‌های اشرشیاکلی و استافیلوکوکوس اورئوس مورد بررسی قرار گرفت. خاک رس اصلاح‌شده با نقره توسط واکنش تبادل یونی در محلول نیترات نقره به دست آمد و فیلم‌های پلیمری با روش اختلاط مذاب در اکسترودر دوپیچه تهیه شدند. ویژگی‌های فیلم‌های نانوکامپوزیتی پلی‌اتیلن با دانسیته پائین حاوی نان...

MicroRNAs play important roles in laryngeal carcinoma and other cancers. However, the expression of microRNAs in paracancerous tissue has been studied less. Here, using laser capture microdissection (LCM), we detected the expression of microRNAs in paracancerous tissues. Among all down-regulated microRNAs in the center area of tumor tissues, only miR-30b expression was significantly reduced in ...

Transport, mechanical and global migration data concern multilayer food packaging films with different layouts, all incorporating a layered silicate/polyamide nanocomposite as oxygen barrier layer, and a low-density polyethylene (LDPE) as moisture resistant layer in direct contact with food. The data are related to "Tuning of co-extrusion processing conditions and film layout to optimize the pe...

High solid content poly (styrene-co-butyl acrylate) latex ( with 20% and 40% solid content) including high amounts of Cloisite 30B (7 wt% and 10 wt%) were kinetically investigated. Gravimetric method via measuring the rate of polymerization, number of particles and average number of radicals per particle was used. Results showed that by increasing the solid content; the average diameter of poly...

ERG (ETS-related gene) belongs to the ETS family of transcription factors, and has been recently reported to contribute to homeostatic balance in skeleton cell plasticity. MicroRNA-30 (miR-30) family is also demonstrated to play a role in controlling chondrocyte differentiation. The current study investigated the miR-30b and ERG expression in articular cartilage of osteoarthritis (OA) patients....

Abstract The addition of nanoparticles could allow to upgrade the performances biopolymers, making them fit replace petroleum-based plastics. In order maximize sustainability benefits bio-nanocomposites, it is fundamental opportunely tune their bulk properties by acting on nanostructure. particular, in nanocomposite blends final morphologies are highly dependent selective localization nanoparti...
