BACKGROUND Atherosclerosis is characterized by an early inflammatory response involving proinflammatory mediators such as platelet-activating factor (PAF)-like phospholipids, which are inactivated by PAF-acetylhydrolase (PAF-AH). The effect of adenovirus-mediated expression of PAF-AH on injury-induced neointima formation and spontaneous atherosclerosis was studied in apolipoprotein E-deficient ...

The effects of acetone +/- spermine on the high (AH-I) and low (AH-II) affinity forms of aniline hydroxylases in the mouse hepatic microsomes were investigated under in vitro conditions. The addition of either acetone or spermine alone stimulated both AH-I and AH-II activities at low concentration while some decline in stimulation was noted at higher concentrations. In the presence of both the ...

OBJECTIVE The more atherogenic lipid profile seen in peritoneal dialysis (PD) patients cannot fully explain the increased incidence of atherosclerosis in this population. Oxidative modification of low-density lipoproteins (LDL) is considered to play a central role in the atherogenic process, whereas high-density lipoprotein (HDL) protects LDL from oxidation. On the other hand, it has been sugge...

In glaucoma, lowered intraocular pressure (IOP) confers neuroprotection. Elevated IOP characterizes glaucoma and arises from impaired aqueous humor (AH) outflow. Increased resistance in the trabecular meshwork (TM), a filter-like structure essential to regulate AH outflow, may result in the impaired outflow. Flow through the 360° circumference of TM structures may be non-uniform, divided into h...

OBJECTIVE Plasma platelet-activating factor (PAF) acetylhydrolase (AH) is an enzyme bound with lipoproteins that degrades not only PAF but also PAF-like oxidized phospholipids that are proposed to promote atherosclerosis. In this study, we investigated the distribution of PAF-AH protein among lipoprotein classes by using adenovirus-mediated gene transfer in mice, and we examined its effects on ...

Alveolar hemorrhage (AH) is a heterogeneous clinical syndrome with a high mortality rate that is characterized by extensive bleeding into the alveolar spaces. AH usually develops secondary to immunological disease and, less frequently, to drug use. Presently described is the case of an 86-year-old woman with AH who had been using rivaroxaban for 6 months.

BACKGROUND Platelet-activating factor (PAF) and PAF-like phospholipids are inactivated by PAF-acetylhydrolase (PAF-AH). Using nonhyperlipidemic animals, we tested whether local expression of PAF-AH into injured arteries might induce antithrombotic and antiinflammatory effects.Method and Results- Balloon-injured rabbit carotid arteries were infected at the time of injury with an adenovirus expre...

Amyloid h-peptide (Ah) is the major constituent of senile plaques, a pathological hallmark of Alzheimer’s disease (AD) brain. It is generally accepted that Ah plays a central role in the pathophysiology of AD. Ah is released from cells under entirely normal cellular conditions during the internalization and endosomal processing of amyloid precursor protein (APP). However, accumulation of Ah can...

BACKGROUND AND AIMS Clinical manifestations of hepatitis A virus (HAV) infection vary from mild to fulminant hepatic failure (FHF) in adults. We investigated the relationship between laboratory findings, including viral load, and clinical outcomes in patients with acute hepatitis A (AHA) and evaluated predictive factors for severe acute hepatitis (s-AH). METHODS We analyzed the clinical manif...
