The goal of this study is to investigate cerebral blood flow (CBF),Diffusion, T2, and vascular responses to 5% CO2inhalation in a mildTBI model in rats. Rats (n=8) underwent a 6mm craniotomy over theleft primary motor/somatosensory cortex and were impacted using apneumatic cortical impactor (impact velocity 5.0 m/s, 250ls dwelltime, and 1mm depth)...

Manganese is a calcium analog and MRI contrast agent. The purposeof this study was to evaluate the utility of manganese-enhanced MRI( MEMRI) in hyperacute, acute, and subacute phases of experimentalmoderate TBI. MnCl2*4H2O was infused at a rate of 1.8 mL/hr for 30minutes before TBI via tail vein at doses of 87.5 mg/kg (n=4) or29.17 mg/kg (n=4). Ane...

Time dependent mechanical properties of magnetic polymer films were investigated. These polymer films, synthesised by using solution polymerisation followed by the inverse emulsion process, consist of poly (MMA-co-MAA-co-BA) and different weight ratios of magnetite nano-particles. This study deals with the influence of weight ratios of magnetite na...

Hydrogels have inherently weak mechanical strength. However, the advantages of bio-compatibility and hydrophilicity make hydrogels become biomaterials for many medical applications. Due to its low friction and high mechanical strength, UV polymerized PAA-Alg-Si (Polyacrylic acid-Alginate-Silica) hydrogel has the potential to be used to repair the d...

Unlabelled: Finishing in orthodontics can be challenging and can involve use of various techniques and armamentarium. This article reports a study that evaluates a procedure for using a thicker Aligner at the end of treatment to aide in finishing and also to determine if this would reduce the need for additional "case refinement" Aligners at the e...

Diseases of specific fibrocartilaginous joints are especially common in women of reproductive age, suggesting that female hormones contribute to their etiopathogenesis. Previously, we showed that relaxin dose-dependently induces matrix metalloproteinase (MMP) expression in isolated joint fibrocartilaginous cells. Here we determined the effects of r...

Fecal radiobioassay is a sensitive tool to estimate intake of radionuclides, especially for insoluble or poorly absorbed actinides. To increase efficiency and reduce turnaround time, improvements were introduced in the sample digestion step of a fecal bioassay method to rapidly detect Pu and Am. The acid- and microwave-digestion of the spiked fecal...

A high-performance liquid chromatography (HPLC)-based method was developed to look for the presence of characteristic urinary metabolites associated with different tritium-exposure situations. Non-volatile metabolites in urine were isolated by evaporating an aliquot of urine samples, at room temperature under nitrogen, from animals percutaneously e...
