Background: Immunopathological and inflammatory processes play important roles in the initiation and development of Ischemic Heart Disease (IHD). Objective: The aim of this study was to evaluate the serum levels of several autoantibodies including rheumatoid factor (RF), anti-nuclear antibodies (ANA), anti-small nuclear ribonucleoprotein (anti-Sm), anti-phosphatidylserine (anti-PS) and anti-car...
The Shinnar-Le Roux (SLR) radiofrequency (RF) pulse design algorithm is widely used for designing slice-selective RF pulses due to its intuitiveness, optimality, and speed. SLR is limited, however, in that it is only capable of designing one-dimensional pulses played along constant gradients. We present a nonuniform SLR RF pulse design framework that extends most of the capabilities of classica...
In software defined radio systems, placing the analog-todigital converter (ADC) near the antenna part in the block diagram of the receiver is desired to improve the flexibility of the system. The radio frequency (RF) sampling method, in which the received signal is sampled at the RF stage, realizes such structure. The undersampling is a potential method to sample the RF signal using the existin...

A method to design multiband RF pulses for magnetic resonance imaging is described. The method is based on the Shinnar-Le Roux transform and involves a phase correction that provides control over the phase of the excited bands. The theory behind the method and this phase correction is outlined. The method is demonstrated with the design of RF pulses for Hadamard encoding and Haar wavelet encodi...
Objective. The aim of this study was to evaluate sex specific differences of metabolic and clinical characteristics of treated hyperlipidemic men and women (HL-men and HL-women). Methods. In this study vascular and metabolic characteristics of 35 HL-women and 64 HL-men were assessed. In addition a sex specific analysis of metabolic and nutritional habits of HL-patients with prediabetes (HL-IGR)...
کمپلکس های باز شیف چهار دندانه نامتقارن حاوی اتم های دهنده o3n با فلزات نیکل، روی و مس سنتز شدند. در تهیه این کمپلکس ها از تراکم فنیلن دی آمین با کتون های 2-هیدروکسی استوفنون و 1-هیدروکسی2-استونفتون به ترتیب نیم واحدهای n- (2- هیدروکسی استو فنون)- 1- آمینو- 2-فنیلن ایمین (hl) و n- (1- هیدروکسی 2- استونفتون)- 1- آمینو- 2-فنیلن ایمین (?hl) تهیه شدند. در مرحله بعد از واکنش الگو سازی hl با نمکهای ن...
In this paper, a BSIMSOI RF gate resistance model for FDSOI MOSFET is introduced and verified. With the addition of the gate resistance model, the RF characteristic of FDSOI MOSFET could be modeled well. Self-heating effect (SHE) will affect RF data fitting significantly. A simple method to extract thermal resistance is proposed.
OBJECTIVE To determine the markers of systemic inflammation in soft tissue rheumatic disorders (STRDs). STUDY DESIGN Case series. PLACE AND DURATION OF STUDY Rheumatology Clinic, Yazd, Iran, from November 2010 to December 2011. METHODOLOGY Patients aged 20 years or above with known diagnosis of STRD according to clinical criteria and/ or paraclinical investigations for at least 3 weeks du...
hodgkin lymphoma (hl) accounts for about 10% of all childhood cancers. five-year survival rates with modern therapies are now approaching >90-95% as a consequence of its significant sensitivity to both chemotherapy and radiation. the current challenge is to determine how much therapy is needed to improve survival and how to adapt treatment to the patient to prevent these long term toxicities. t...
