Ig heavy chain variable region (VH) genes expressed by human diffuse large-cell lymphoma (DLC) and follicular lymphoma (FL) were identified and analyzed with respect to germline gene families. In 67 cases of FL, VH region genes were expressed in a pattern similar to that of normal B cells, with a predominance of the large VH3 gene family being used. In contrast, of the 17 cases of DLC, there wa...

Frictional behavior of nano-undulated diamond-like carbon (DLC) films deposited by plasma assisted chemical vapor deposition (PACVD) process was investigated. In order to prepare the nano-undulated DLC film, a Si wafer with nano-sized Ni dots was prepared by rapid thermal annealing of Ni thin films. Since the structure of DLC film deposited by PACVD was independent of the substrate materials an...

A nanostructured diamond-like carbon (DLC) coated digital versatile disk (DVD) target is presented as a matrix-free sample support for application in laser desorption/ionization mass spectrometry (LDI-MS). A large number of vacancies, defects, relative sp(2) carbon content, and nanogrooves of DLC films support the LDI phenomenon. The observed absorptivity of DLC is in the range of 305-330 nm (n...

A broad array of carbon-based thin films, such as diamond, diamond-like carbon (DLC), and others, have been developed over the last several years [1]. These materials exhibit high strength and stiffness, low friction and wear, tolerance to withstand harsh physical and chemical conditions, and can form smooth, continuous, conformal coatings. This has resulted in their use in a wide range of appl...

In this work, the delay limited capacity (DLC) of orthogonal frequency division multiplexing (OFDM) systems is investigated. The analysis is organized into two parts. In the first part, the impact of system parameters on the OFDM DLC is analyzed in a general setting. The main results are that under weak assumptions the maximum achievable single user DLC is almost independent of the distribution...

OBJECTIVE This study investigated the effect of isoflurane pretreatment on cardiopulmonary bypass (CPB)-related lung injury. METHODS Twelve dogs were randomly divided into two groups of six each. In one group, 1.0 minimum alveolar concentration (MAC) of isoflurane was dministered for 30 min before CPB, while the control group received no anaesthetic. Both groups then underwent 100 min of mild...

Modeling and simulation of non-linear quarter-car suspension system for two air spring models (traditional dynamic new spring) are contrasted in terms (RMS) sprung mass acceleration, load coefficient, the vertical displacement, they compared. Two three (DOF) mathematical quarter implemented MATLAB/Simulink platform. The Ride Comfort (RC), Dynamic Load Coefficient (DLC) Road Handling (RH) respon...

BACKGROUND Previous studies comparing early laparoscopic cholecystectomy (ELC) with delayed laparoscopic cholecystectomy (DLC) for acute cholecystitis were incomplete. A meta-analysis was undertaken to compare the cost-effectiveness, quality of life, safety and effectiveness of ELC versus DLC. METHODS PubMed, Embase, the Cochrane Library and Web of Science were searched for randomized clinica...

The carbon bonding ratio in diamond-like carbon (DLC) thin films has been estimated from the e2 spectra obtained by spectroscopic ellipsometry. A method has been developed to find out the atomic fractions of spand sp-bonded carbon atoms by combining the various features of the existing methods. The atomic fraction of sp-bonded carbon atoms has been determined by fitting the gaussian curves in t...

We have ever developed micro dialysis system that consists of micro channels and polyethersulfone (PES) membranes. However, when blood was used in dialysis experiments, platelets adhered to the surface of membrane and performance of the membrane degraded. Therefore, we modify the surface of PES membranes by coating fluorinated diamond-like carbon (F-DLC). We examined antithrombogencity of the F...
