In response to the 1984 St. Louis encephalitis (SLE) epidemic in the Los Angeles Basin of southern California (USA), an investigative program was initiated to evaluate the interactive components of the SLE virus transmission cycle. From 1987 through 1996 (10 yr), 52,589 birds were bled and their sera tested for SLE and western equine encephalomyelitis (WEE)(More)
Dietary fats have been shown to promote the translocation of bacterial endotoxins from the gut into circulation, which may induce systemic inflammation and modulate the inflammatory response of circulating immune cells. The aim of this study was to determine the effect of the postprandial milieu on inflammation and the inflammatory response of antigen(More)
BACKGROUND A high-fat diet promotes postprandial systemic inflammation and metabolic endotoxemia. We investigated the effects of three consecutive high-fat meals on endotoxemia, inflammation, vascular function, and postprandial lipid metabolism in patients with type 1 diabetes. METHODS Non-diabetic controls (n = 34) and patients with type 1 diabetes (n =(More)
BACKGROUND The nuclear factor κ light-chain enhancer of activated B cells (NF-κB) signaling pathway is a key regulator of immune responses. Accordingly, mutations in several NF-κB pathway genes cause immunodeficiency. OBJECTIVE We sought to identify the cause of disease in 3 unrelated Finnish kindreds with variable symptoms of immunodeficiency and(More)
High serum lipopolysaccharide (LPS) activity in normoalbuminuric patients with type 1 diabetes (T1D) predicts the progression of diabetic nephropathy (DN), but the mechanisms behind this remain unclear. We observed that treatment of cultured human podocytes with sera from normoalbuminuric T1D patients with high LPS activity downregulated(More)
We report on a 74-year-old male patient with chronic obstructive pulmonary disease (COPD) who developed an invasive fungal disease of the facial bones after several teeth were extracted. He had recently suffered an exacerbation of COPD, treated with a course of corticosteroid therapy. Mucormycosis is an opportunistic fungal pathogen that has the ability to(More)
Loss of podocytes is an early feature of diabetic nephropathy (DN) and predicts its progression. We found that treatment of podocytes with sera from normoalbuminuric type 1 diabetes patients with high lipopolysaccharide (LPS) activity, known to predict progression of DN, downregulated CDK2 (cyclin-dependent kinase 2). LPS-treatment of mice also reduced CDK2(More)
Bacterial endotoxins have been associated with chronic inflammation and the development and progression of diabetic nephropathy. We hypothesized that subjects with high serum lipopolysaccharide activity also carry remains of bacterial DNA in their system. Serum-derived bacterial DNA clones were isolated and identified from 10 healthy controls and 14(More)
Hypoxemia is common in diabetes, and reflex responses to hypoxia are blunted. These abnormalities could lead to cardiovascular/renal complications. Interval hypoxia (IH) (5-6 short periods of hypoxia each day over 1-3 weeks) was successfully used to improve the adaptation to hypoxia in patients with chronic obstructive pulmonary disease. We tested whether(More)
