Hyper-Rayleigh scattering (HRS) from liquid nitrobenzene was measured for several combinations of linear polarized incident and scattered light, for a range of scattering angles near 90 degrees . The observations show that the HRS intensity is dominated by the polar transverse collective mode contribution, and support a model where the long range dipole-dipole orientation correlations in a pola...

Introduction Mevalonate kinase deficiency (MKD) is a rare autosomal recessive disorder causing 1 of 2 phenotypes, hyperimmunoglobulin D syndrome and mevalonic aciduria, presenting with recurrent fever episodes, often starting in infancy, and sometimes evoked by stress or vaccinations. This autoinflammatory disease is caused by mutations encoding the mevalonate kinase (MVK) gene and is classifie...

Patients with the hyperimmunoglobulin E and recurrent infection syndrome (HIE) characteristically have frequent skin and respiratory infections caused by Staphylococcus aureus. We have developed a set of enzyme-linked immunosorbent assays that use whole S. aureus (Wood's strain) immobilized on 0.22-micrometers filters and highly specific, affinity-purified enzyme conjugates of goat anti-human I...

The CD40 ligand (CD40L) and CD40 are two molecules belonging to the TNF/TNF receptor superfamily, and their role in adaptive immune system has widely been explored. However, the wide range of expression of these molecules on hematopoietic as well as nonhematopoietic cells has revealed multiple functions of the CD40/CD40L interactions on different cell types and processes such as granulopoiesis....

BACKGROUND Tuberculosis is a devastating disease due to its rapid transmission and high rate of mortality. Ningxia Hui Autonomous Region (NHAR), located in the North-west, is one of the poorest provinces in China and national surveys have shown TB has been hyper endemic in NHAR for several decades. As no active surveys had been undertaken since the initiation of the DOTS control program across ...

Hyper-Rayleigh scattering (HRS) is sensitive to long-range molecular orientation correlation in isotropic liquids composed of dipolar molecules. The correlation functions that appear in the calculation of HRS mediated by the vector part of the first hyperpolarizability β are the same as the correlation functions for the homogeneous isotropic random vector fields that appear in the description o...

The photon statistics of various nonlinear optical processes has been a subject of increasing interest in recent years. In particular, photon statistics for the usual Raman process has been analyzed theoretically by Simaan in detail. ' The similar hyper-Raman (HR) process has also been studied already by Simaan, who formulated the master equation of the process giving the solution by the Laplac...
