OBJECTIVE In type 1 diabetes, plantar fascia, a collagen-rich tissue, is susceptible to glycation and oxidation. Paraoxonase-1 (PON1) is an HDL-bound antioxidant enzyme. PON1 polymorphisms have been associated with susceptibility to macro- and microvascular complications. We investigated the relationship between plantar fascia thickness (PFT) and PON1 gene variants, p.Leu54Met, p.Gln192Arg, and...

OBJECTIVE Direct measurement of collagen glycation requires skin biopsy, which is invasive. We hypothesized that measurement of plantar fascia thickness (PFT) by ultrasound is an alternative index of tissue glycation and a marker of microvascular disease. RESEARCH DESIGN AND METHODS This was a prospective longitudinal study of microvascular complications in 344 adolescents with type 1 diabete...

Promoting regenerative repair, including neurogenesis and angiogenesis, may provide a new therapeutic strategy for treatment of stroke. P53, a well-documented transcription factor, has been reported to be involved in cerebral ischemia and also serves as an important regulator of vascular endothelial growth factor (VEGF). However, the role of p53 in endogenous regenerative repair after brain isc...

Pore-forming toxins (PFTs) constitute the single largest class of proteinaceous bacterial virulence factors and are made by many of the most important bacterial pathogens. Host responses to these toxins are complex and poorly understood. We find that the endoplasmic reticulum unfolded protein response (UPR) is activated upon exposure to PFTs both in Caenorhabditis elegans and in mammalian cells...

PURPOSE OF REVIEW Placebo-controlled randomized trials have demonstrated the efficacy of clopidogrel in combination with aspirin across a broad range of clinical presentations. Recent trials have addressed several remaining issues regarding clopidogrel therapy. RECENT FINDINGS Three randomized trials examined the role of platelet function testing (PFT) in clopidogrel-treated patients. The res...

OBJECTIVE Interstitial lung disease (ILD) is a common extra-articular manifestation of rheumatoid arthritis (RA) and a significant cause of morbidity and mortality. The objective of this study was to define high-resolution chest CT (HRCT) and pulmonary function test (PFT) abnormalities capable of identifying asymptomatic, preclinical forms of RA-ILD that may represent precursors to more severe ...

We examined the effects of parent adherence on child outcomes in two treatment strategies for the Predominantly Inattentive Presentation of attention deficit/hyperactivity disorder (ADHD-I): behavioral parent training adapted for ADHD-I (Parent-Focused Therapy [PFT]) and a multicomponent intervention that combined PFT, a child life skills group, and a classroom intervention (Child Life and Atte...

Diverse bacterial species produce pore-forming toxins (PFT) that can puncture eukaryotic cell membranes. Host cells respond to sublytic concentrations of PFT through conserved intracellular signaling pathways, including activation of mitogen-activated protein kinases (MAPK), which are critical to cell survival. Here we demonstrate that in respiratory epithelial cells p38 and JNK MAPK were phosp...

TRAIL and agonistic death receptor-specific antibodies can induce apoptosis in cancer cells with little cytotoxicity to normal cells. To improve TRAIL-induced antitumor effects, we tested its effectiveness in combination with pifithrin (PFT)-μ, which has the potential to inhibit HSP70 function and autophagy, both of which participate in TRAIL resistance in cancer cells. Among the four human pan...
