Objective(s): Existing studies have demonstrated that intravenous and intramyocardial-administrated mesenchymal stem cells (MSCs) lead to tissue repair after cardiac disorders. We compared the efficiency of both administration methods.Materials and Methods: A rat model of isoproterenol-induced heart failure (ISO-HF) was established to co...
سابقه و هدف: شواهدی در زمینه اثرات متقابل سطوح انسولین و دآسیل گرلین (dag) وجود دارد، اما ارتباط بین درصد اسیدهای چرب اشباع و غیر اشباع در روغن های خوراکی مختلف و در قالب رژیم غذایی پرچرب با ترشح هورمون های انسولین و dag بررسی نشده است. مطالعه حاضر به منظور بررسی و مقایسه تأثیر منابع مختلف چربی رژیمی و میزان اشباع اسیدهای چرب بر سطوح پلاسمایی انسولین و dag و تعیین ارتباط dag با عملکرد انسولین ا...

nowadays nmr spectroscopy becomes a powerful tool in chemistry because of the nmr chemical shifts. hartree–fock theory and the gauge-including atomic orbital (giao) methods are used in the calculation of 29si nmr chemical shifts of various silicate species in the silicate solution as initial components for zeolite synthesis both in gas and solution phase. calculations have been performed at geo...
The study investigated whether a persistent impairment of insulin secretion resulting from mild protein restriction predisposes to loss of glucoregulatory control and impaired insulin action after the subsequent imposition of the diabetogenic challenge of high-fat feeding. Offspring of dams provided with either control (20% protein) diet (C) or an isocaloric restricted (8%) protein diet (PR) we...
Background and purpose: Heart failure (HF) is a serious issue concerning public health in all countries. Assessment and monitoring of mortality and influencing factors are of great importance in HF treatment programs. This study was conducted to determine the incidence of HF and the associated factors in Iran. Materials and methods: In this study, we did two main, independent analyses. One was...
Background and Aim: The aim of this study was to investigate the shear bond strengthof composite to Emax porcelain using different methods of ceramic surface preparation (in vitro). Material and Methods: In this laboratory study, 36 porcelain disks were made and divided into four equal groups. The first group was prepared by sandblasting with 50 micron alumina particles, in the second group rec...
This paper presents a solution to increase the throughput of an HF (High Frequency) physical (PHY) layer in particular to allow for services such as IP over HF. Additionally, this new PHY layer can improve the adaptability of the waveform to the channel variations, in particular to limit the retransmissions due to errors. Taking into consideration the existing HF spectrum occupancy and its high...
