Digital image correlation (DIC) is a widely used optical metrology for surface deformation measurements. DIC relies on nonlinear optimization method. Thus an initial guess is quite important due to its influence on the converge characteristics of the algorithm. In order to obtain a reliable, accurate initial guess, a reliability-guided digital image correlation (RG-DIC) method, which is able to...

Differential interference contrast (DIC) microscopy is an inherently qualitative phase-imaging technique. What is obtained is an image with mixed phase-gradient and amplitude information rather than a true linear mapping of actual optical path length (OPL) differences. Here we investigate an approach that combines the transport-of-intensity equation (TIE) with DIC microscopy, thus improving dir...

Clinically overt, preoperative, disseminated intravascular coagulation (DIC) is not common in patient with aortic aneurysm. However, cases with large and expanding aneurysm are especially prone for this coagulopathy. Contrary to the clinically overt form compensated DIC in patients with aortic aneurysm seems frequent and is probably underdiagnosed. The compensated DIC may be recognized, even wi...

Objective The mortality rate due to disseminated intravascular coagulation (DIC) is higher in patients with lung cancer than in those without. We examined the effect of treatment with thrombomodulin alfa (TM-α) for DIC in lung cancer patients. Methods Subjects were 57 patients with DIC (43 men, 14 women; mean age, 71.7 years), comprising 31 with lung cancer and 26 without. DIC patients with or ...

In two cases of transfusion-associated graft-versus-host disease (TA-GVHD), severe bleeding tendencies were observed besides the characteristic features of the disease. An elevation of fibrin degradation products (FDP), D-dimer, thrombin-antithrombin III complex (TAT) and plasmin-alpha 2 plasmin inhibitor complex (PIC), was revealed. These findings were compatible with disseminated intravascula...

Imaging models for differential-interference-contrast (DIC) microscopy are presented. Two- and three-dimensional models for DIC imaging under partially coherent illumination were derived and tested by using phantom specimens viewed with several conventional DIC microscopes and quasi-monochromatic light. DIC images recorded with a CCD camera were compared with model predictions that were generat...

Sister chromatid cohesion (SCC), which is established during DNA replication, ensures genome stability. Establishment of SCC is inhibited in G2. However, this inhibition is relived and SCC is established as a response to DNA damage, a process known as Damage Induced Cohesion (DIC). In yeast, Chk1, which is a kinase that functions in DNA damage signal transduction, is considered an activator of ...

DICE1 (deleted in cancer 1), first identified in human lung carcinoma cell lines, is a candidate tumor suppressor, but the details of its activity remain largely unknown. We have found that RNA interference of its C. elegans homolog (DIC-1) produced inviable embryos with increased apoptosis, cavities in cells and abnormal morphogenesis. In the dic-1(RNAi) germ line, ced-3-dependent apoptosis in...

AIM The aim was to investigate whether dexmedetomidine had a toxic effect on cerebral neurons when it was administered centrally into the cerebrospinal fluid by the intracisternal route. MATERIAL AND METHODS Eighteen rats were anesthetized and the right femoral artery was cannulated. Mean arterial pressures, heart rates, arterial carbon dioxide tension, arterial oxygen ten...
