CD200 has been proved to play a role in immuno-inflammatory reaction. However, little information is available on CD200 in the acute stage of cerebral ischemia. We investigated the association between neuronal death and expression of CD200, and explored the relationship between CD200 and microglia in cerebral ischemic mice. Firstly, localization of CD200 expression in the normal brain tissue was detected by immunofluorescent assay. Then, focal cerebral ischemia was induced in mice by permanent middle cerebral artery occlusion (pMCAO) and then cortical tissues were collected at 6, 12, 24 and 48 h after surgery...

As a specific biomarker in neonatal hypoxic-ischemic encephalopathy (HIE), the measurement of neuron-specific enolase (NSE) has been advocated as a predictor of outcome in neurological injury. However, the measured levels of NSE may be influenced by hemolysis. In the current study, the change in the concentration of NSE in serum was measured by chemiluminescence prior to and following the addition of individual frozen and thawed red blood cells from 86 neonates that were collected within 24 h of birth. The changes in the concentration of NSE were compared with the changes in the concentration of hemoglobin (Hb), measured by the hemoglobin cyanide (HiCN) method, to establish a correction formula...

BACKGROUND: Recently, we came with the theory of a possible relationship between a group of testicular and pancreatic tumors. We used one case of a pancreatic analogue solid pseudopapillary neoplasm of the testis composed partially of areas reminiscent of solid pseudopapillary neoplasm (SPN) of the pancreas and partially of structures identical to primary signet ring stromal tumor of the testis (PSRSTT) as a connecting link between these two entities. After demonstrating that PSRSTT and pancreatic analogue SPN of the testis share the same immunoprofile and genetic features characteristic for pancreatic SPN, we came to the conclusion that pancreatic analogue SPN of the testis and PSRSTT represent a morphological spectrum of a single entity and that both are related to the pancreatic SPN...

Nigella sativa seedcake phenolic extract (NSE), as compared to tannic acid (TA), was evaluated for its effect on film-forming ability of chitosan. These films were evaluated for their tensile strength, elongation, water vapor permeability (WVP), type of bonding, color, surface morphology, polyphenol and in vitro antioxidant activity release profile. At 7.5% (v/v of film-forming solution), NSE led to 42% decrease in tensile strength but improved the elongation by 66%, contradicting the effect of TA in chitosan films...

A general property of disordered proteins is their structural expansion that results in a high molecular flexibility. Structure and dynamics of bovine serum albumin (BSA) denatured by guanidinium hydrochloride (GndCl) were investigated using small-angle neutron scattering (SANS) and neutron spin-echo spectroscopy (NSE). SANS experiments demonstrated the relevance of intra-chain interactions for structural expansion. Using NSE experiments, we observed a high internal flexibility of denatured BSA in addition to centre-of-mass diffusion detected by dynamic light scattering...
