Hirudin, a potent and specific thrombin inhibitor, is a protein of nonhuman origin and therefore potentially immunogenic. The primary objectives of this investigation were to determine the incidence of antihirudin antibodies (ahir-ab) in patients with heparininduced thrombocytopenia (HIT) who received lepirudin as parenteral anticoagulation and to determine the incidence of death, limb amputati...
Current conveyors are unity gain active elements exhibiting high linearity, wide dynamic range and high frequency performance than their voltage mode counterparts. The new current conveyor operating at low-voltage supplies high input impedance and low output impedance and consumes less power. In this study, a new low-voltage class AB second generation current conveyor (AB CCII) is presented whi...
This paper describes a power amplifier, employing parallel-connected laterally diffused metal–oxide semiconductor (LDMOS) devices with optimized channel widths and bias offsets to approximate ideal square-law behavior of the overall transconductance in class-AB operation. The proposed method results in a significant linearity improvement over a large dynamic range in comparison to a conventiona...
The human class I MHC molecules are known to generally exist on the cell surface either as peptide-containing complexes of H chain (alpha-chain) and beta(2)-microglobulin (beta(2)m) or as beta(2)m-free H chains incapable of binding peptides. In this study, a uniquely conformed peptide-containing beta(2)m-free HLA-B2705 H chain has been isolated using the recently described highly efficient perf...
دربررسی شیوع ترومبوز بطن چپ و رابطه آن با نوع و دفعات آنفارکتوس و درجه نارسائی قلبی (killip class)، مطالعه اکوکاردیوگرافی در 60 بیمار انجام شد . در مجموع 14 ترومبوز یافت شد . 37 بیمار آنفارکتوس قدامی داشتند که 12 مورد با lvt همراه بود . 10بیمار آنفارکتوس باردوم آنها بود که 8 مورد lvt داشتند. 18 بیمار در killip class iii بودند که 8 مورد lvt مشاهده شد. تمام بیماران آکینزی یا دیسکینزی آپیکال داشتن...
In this work, we introduce the concept of classical 2-absorbing secondary modules over a commutative ring as a generalization of secondary modules and investigate some basic properties of this class of modules. Let $R$ be a commutative ring with identity. We say that a non-zero submodule $N$ of an $R$-module $M$ is a emph{classical 2-absorbing secondary submodule} of $M$ ...
To perform correct measurements on a true digital audio amplifier (TDAA), it is important to understand the characteristics of the device, especially in comparison with conventional linear amplifiers such as class-A and class-AB. This report provides an overview of TI’s proprietary digital amplification technology and information about how measurements on TDAA’s must be performed in order to ob...
Pigeons trained on successive AB symbolic matching show emergent BA antisymmetry if they are also trained on successive AA oddity and BB identity (Urcuioli, 2008, Experiment 4). In other words, when tested on BA probe trials following training, they respond more to the comparisons on the reverse of the nonreinforced AB baseline trials than on the reverse of the reinforced AB baseline trials (th...
