BACKGROUND AND PURPOSE Although activation of the N-methyl-D-aspartate (NMDA) receptor is thought to contribute to altered cerebrovascular regulation after traumatic brain injury, the effects of such injury on the vascular response to NMDA itself has been less well appreciated. The newly described opioid nociceptin/orphanin FQ (NOC/oFQ) elicits pial artery dilation, at least in part, in a prost...

BACKGROUND AND PURPOSE--Endothelin-1, in concentrations similar to that present in cerebrospinal fluid after fluid percussion brain injury (FPI), increases superoxide anion (O2-) production. Endothelin-1 also contributes to altered cerebral hemodynamics after FPI through impairment of ATP-sensitive K+ (KATP) channel function through protein kinase C (PKC) activation. Generation of O2- additiona...

Abstract This investigation was aimed to evaluate the effects of Silybum marianum seed, Thymus vulgaris , and Rosmarinus officinalis powders their combination in alleviating risks aflatoxin B1 (AFB1) young broiler chicks. One-day-old Ross 308 male chickens were allocated 6 experimental groups from d 1 21. The dietary included: Negative control (NC) received basal diet, Positive (PC) containing ...

Tretinoin tocoferil is an a-tocopherol ester of all-trans retinoic acid (RA) and safely used in the treatment of skin ulcer. Tretinoin tocoferil inhibited proliferation of human promyelocytic leukemia HL-60 cells and induced granulocytic differentiation of the cells, but less than RA. a-Tocopherol did not affect differentiation of HL-60 cells, but at high concentrations enhanced its nitroblue t...

Polymorphonuclear neutrophils' chemotaxis, surface charge, superoxide anions generation, NBT (nitro blue tetrazolium) reduction and intracellular lysozyme, and beta-glucuronidase content were estimated in patients with type I diabetes mellitus in a similar state of metabolic control. The chemotaxis of diabetic cells toward bacterial chemotactic factors was similar to controls, whereas migration...

SERS based immunoassays for point-of-care diagnostics are a promising tool to facilitate biomarker detection early disease diagnosis and control. The technique is on sandwiched system in which antigen first captured by selective plasmonic paper substrate then labeled an extrinsic Raman label (ERL), consisting of 60 nm gold nanoparticle (AuNP) functionalized with mixed monolayer antibody 4-nitro...

The extent of left ventricular (LV) dyssynergy was assessed noninvasively in 19 dogs with two-dimensional echocardiographic short-axis sections during myocardial ischemia and infarction. After coronary occlusion, two-dimensional echocardiography uniformly indicated an increase in LV end-diastolic volume and a decrease in LV ejection fraction. Two-dimensional echocardiographic measurements of dy...

A B S T R A C T The ability of highly purified human leukocytic pyrogen (LP) to stimulate neutrophil oxygen-dependent metabolism was studied. Human peripheral blood neutrophils exposed to leukocytic pyrogen in vitro demonstrated an increase in the percentage of neutrophils reducing nitroblue tetrazolium (NBT) dye and a marked stimulation of superoxide dismutase inhibitable reduction of ferricyt...
