BACKGROUND Cellular cardiomyoplasty has been proposed as an alternative strategy for augmenting the function of diseased myocardium. We investigated the potential of human mesenchymal stem cells (hMSCs) from adult bone marrow to undergo myogenic differentiation once transplanted into the adult murine myocardium. METHODS AND RESULTS A small bone marrow(More)
NicVAX, a nicotine vaccine (3'AmNic-rEPA), has been clinically evaluated to determine whether higher antibody (Ab) concentrations are associated with higher smoking abstinence rates and whether dosages and frequency of administration are associated with increased Ab response. This randomized, double-blinded, placebo-controlled multicenter clinical trial (N(More)
The coupling of choline transport to acetylcholine synthesis has been investigated by measurement of the isotopic dilution of a pulse of [3H]choline during its incorporation into the recently synthesised acetylcholine of cerebral cortex synaptosomes. Recently synthesised acetylcholine was identified as that containing 14C-labelled precursors introduced by a(More)
The endoplasmic reticulum undergoes rapid, microscopic changes in its structure, including extension and anastomosis of tubular elements. Such dynamism is expected to manifest itself also as rapid intermixing of membrane components, at least within subdomains of the endoplasmic reticulum. Here we present evidence of a similar dynamism in the sarcoplasmic(More)
Smoking is a global healthcare problem. Current smoking cessation rates using behavioral counseling and pharmacotherapeutic interventions have had modest success, with ∼1:5 smokers remaining abstinent long-term. Nicotine vaccines are a new class of immunotherapeutics under development. It is believed that anti-nicotine antibodies arising from vaccination(More)
BACKGROUND Hyperphosphatemia in patients with chronic kidney disease (CKD) contributes to secondary hyperparathyroidism, soft tissue calcification, and increased mortality risk. This trial was conducted to examine the efficacy and safety of calcium acetate in controlling serum phosphorus in pre-dialysis patients with CKD. METHODS In this randomized,(More)

Previous studies have demonstrated a diminution in the bioactivity of the guanine nucleotide-binding regulatory protein that stimulates adenylyl cyclase (Gs) in hearts of the hypertrophic BIO 14.6 Syrian hamster. In this study, we measured functional activity and immunodetectable levels of Gs in a mutant strain of hamsters (BIO 53.58) that develop a dilated(More)
BACKGROUND A potential new treatment in smoking cessation and relapse prevention is nicotine vaccination which is based on active immunization against the nicotine molecule. This immunization will elicit the immune system to produce nicotine-specific antibodies that sequester nicotine in the blood stream, after inhaling tobacco products. The resulting(More)
