It has been shown that the last passage time in certain symmetrized models of directed percolation can be written in terms of averages over random matrices from the classical groups U(l), Sp(2l) and O(l). We present a theory of such results based on non-intersecting lattice paths, and integration techniques familiar from the theory of random matrices. Detailed derivations of probabilities relat...

C-reactive protein (CRP) and surfactant protein A (SP-A) are phosphatidylcholine (PC) binding proteins that function in the innate host defense system. We examined the effects of CRP and SP-A on the surface activity of bovine lipid extract surfactant (BLES), a clinically applied modified natural surfactant. CRP inhibited BLES adsorption to form a surface-active film and the film's ability to lo...

Random lasers are intriguing devices with promising applications as light sources for imaging, sensing, super-resolution spectral analysis or complex networks engineering. can be obtained from optically pumped dyes, optical fibres and crystals electrically semiconductor heterostructures. Semiconductor random usually fabricated by introducing scattering defects into the active layer, adding a de...

Numerous epidemiological and toxicological studies have indicated that respiratory infections are exacerbated following enhanced exposure to airborne particulates. Surfactant protein A (SP-A) and SP-D form an important part of the innate immune response in the lung and can interact with nanoparticles to modulate the cellular uptake of these particles. We hypothesize that this interaction will a...

erythraeus (zaracarus) coleopterus mortazavi, hajiqanbar & saboori, 2012 (acari: parasitengona: erythraeidae) was described based on a single specimen from kerman province, southeastern iran, associated with a scarabaeid beetle, cyphonoxia sp. (coleoptera: scarabaeidae). this species reports for the second time from stored grain (off host) in saqqez and baneh cities, kurdistan province, western...

BACKGROUND The prostate epithelial stem cell has been proposed as the primary origin of neoplastic change in prostate cancer. However, the isolation and characterization of unexpanded prostate epithelial stem cells have proven problematic. METHODS A prostate epithelial side population (SP) has been isolated utilizing a modified Hoechst 33342 dye efflux assay from both benign and malignant pro...

PURPOSE Pterygium is a prevalent ocular surface disorder thought to be triggered by chronic ultraviolet damage to the limbus. One of the enigmatic features of pterygium is its wing-like shape, and the mechanism(s) supporting its centripetal growth remain to be elucidated. Because the growth pattern of pterygia mirrors the radial arrangement of corneal nerves, the authors propose that neuropepti...

Alzheimer'~ rfi o;ease is an age-related neurodegenerative disease and is characterized by the presence of senile plaques (SP), neurofibrillary tangles, and synapse loss. Amyloid-beta, one of the main components of SP, has been known to induce oxidative stress and is highly toxic. Using redox proteomics approaches a number of oxidatively modified proteins were identified in AD and mild cognitiv...
