The blood hyperserotonemia of autism is one of the most consistent biological findings in autism research, but its causes remain unclear. A major difficulty in understanding this phenomenon is the lack of information on fundamental interactions among the developing brain, gut, and blood in the mammalian body. We therefore investigated relationships among(More)
Parkinson's disease (PD) is a movement neurodegenerative disorder, characterized by bradykinesia, rigidity and tremor, constituting difficulties in walking and abnormal gait. Previous research shows that Drosophila expressing human α-synuclein A30P (A30P) develop deficits in geotaxis climbing; however, geotaxis climbing is a different movement modality from(More)
Pharmacological activation of α7 nicotinic acetylcholine receptors (α7 nAChRs) may improve cognition in schizophrenia and Alzheimer's disease. The present studies describe an integrated pharmacological analysis of the effects of FRM-17874, an analogue of encenicline, on α7 nAChRs in vitro and in behavioral and neurophysiological assays relevant to cognitive(More)
OBJECTIVE To demonstrate equivalence between mifepristone 200 mg followed 6 to 8 hours later and 24 hours later by misoprostol 800 microg vaginally for abortion in women up to 63 days of gestation. METHODS Mifepristone 200 mg was swallowed by 1,080 women after which they were randomly assigned to self-administer misoprostol intravaginally 6 to 8 hours(More)
Congestive heart failure (CHF) is associated with an increase of leukocyte infiltration, proinflammatory cytokines, and fibrosis in the heart and lung. Regulatory T cells (Tregs, CD4(+)CD25(+)FoxP3(+)) suppress inflammatory responses in various clinical conditions. We postulated that expansion of Tregs attenuates CHF progression by reducing cardiac and lung(More)
Asymmetric dimethylarginine (ADMA) is an endogenous inhibitor of nitric oxide synthases that limits nitric oxide bioavailability and can increase production of NOS derived reactive oxidative species. Increased plasma ADMA is a one of the strongest predictors of mortality in patients who have had a myocardial infarction or suffer from chronic left heart(More)
OBJECTIVE This study examines bleeding pattern following medication-induced termination of pregnancy, comparing two different dosing schedules of mifepristone and misoprostol. STUDY DESIGN Diary information was analyzed from a randomized, multicenter trial in which women used vaginal misoprostol 800 mug either 6-8 or 24 h following 200 mg of oral(More)
The capacity of β cells to expand in response to insulin resistance is a critical factor in the development of type 2 diabetes. Proliferation of β cells is a major component for these adaptive responses in animal models. The extracellular signals responsible for β-cell expansion include growth factors, such as insulin, and nutrients, such as glucose and(More)
OBJECTIVE To determine if first-trimester elective termination of pregnancy affects cell-free fetal DNA (fDNA) levels in maternal plasma. DESIGN Prospective cohort study. SETTING Clinical and academic research centers. PATIENT(S) One hundred thirty-four women who underwent first-trimester elective termination procedures. INTERVENTION(S) None. MAIN(More)
The SHR, a genetic model for hypertension and the metabolic syndrome, has attenuated leukocyte adhesion to the postcapillary endothelium by an unknown mechanism. Based on recent evidence of elevated levels of MMPs in plasma and on microvascular endothelium of the SHR with cleavage of several receptor types, we hypothesize that the reduced(More)
