Association of serum immunoglobulins levels and eye injuries in sulfur mustard exposed: Sardasht-Iran Cohort Study.

In this study the associations between ocular problems and serum levels of immunoglobulins in sulfur mustard (SM) exposed population 20 years after exposure in context of Sardasht-Iran Cohort Study was explored. Serum immunoglobulins (Ig) levels including IgM, IgA, IgE, IgG, and subclasses of IgG (IgG1, IgG2, IgG3 and IgG4) in 372 SM-exposed patients were titrated and compared with 128 unexposed controls considering their ocular problems. In exposed patients with tearing and blurring of vision, serum IgM levels were significantly lower than matched controls (P=0.

Impact of psychological problems in chemical warfare survivors with severe ophthalmologic complication, a cross sectional study.

Background: Sulfur mustard (SM) has been used as a chemical warfare agent since the early twentieth century.

This study has evaluated the most prominent influences on the psychological health status of patients with severe SM induced ocular injuries.

Association between rs4673 (C/T) and rs13306294 (A/G) haplotypes of NAD(P)H oxidase p22phox gene and severity of stenosis in coronary arteries.

Phagocytic NADH/NADPH oxidase is an important enzyme producing reactive oxygen species within subendothelial space of vessels. Findings have shown that p22phox subunit is an essential element related to the enzyme activity. Since some p22phox polymorphisms are thought to have functional roles in the enzyme thus, we studied the association between rs4673 (C242T) and rs13306294 (A/G) haplotypes and the severity of stenosis in coronary arteries.

Application of "parallel" moiré deflectometry and the single beam Z-scan technique in the measurement of the nonlinear refractive index.

In this paper, the application of "parallel" moiré deflectometry in measuring the nonlinear refractive index of materials is reported. In "parallel" moiré deflectometry the grating vectors are parallel, and the resulting moiré fringes are also parallel to the grating lines. Compared to "rotational" moiré deflectometry and the Z-scan technique, which cannot easily determine the moiré fringe's angle of rotation and is sensitive to power fluctuations, respectively, "parallel" moiré deflectometry is more reliable, which allows one to measure the radius of curvature of the light beam by measuring the moiré fringe spacing.
