The VIVA Trial Vascular Endothelial Growth Factor in Ischemia for Vascular Angiogenesis

Abstract: Background— Recombinant human vascular endothelial growth factor protein (rhVEGF) stimulates angiogenesis in animal models and was well tolerated in Phase I clinical trials. VIVA (Vascular endothelial growth factor in Ischemia for Vascular Angiogenesis) is a double-blind, placebo-controlled trial designed to evaluate the safety and efficacy of intracoronary and intravenous infusions of rhVEGF. Methods and Results— A total of 178 patients with stable exertional angina, unsuitable for standard revascularization, were randomized to receive placebo, low-dose rhVEGF (17 ng · kg−1 · min−1), or high-dose rhVEGF (50 ng · kg−1 · min−1) by intracoronary infusion on day 0, followed by intravenous infusions on days 3, 6, and 9. Exercise treadmill tests, angina class, and quality of life assessments were performed at baseline, day 60, and day 120. Myocardial perfusion imaging was performed at baseline and day 60. At day 60, the change in exercise treadmill test (ETT) time from baseline was not different between groups...

Nitric oxide (NO) and nociceptive processing in the spinal cord.

Abstract: There is considerable evidence to implicate N-methyl-D-aspartate (NMDA) receptor activation in the mechanisms that underly thermal hyperalgesia in the spinal cord As many of the effects of NMDA receptor activation appear to be ultimately mediated through production of nitric oxide (NO), recent reports have begun to define the role of NO in spinal nociceptive processing From this evidence, it is likely that NO, produced in neurons in the spinal cord that contain NO synthase, like NMDA, plays a pivotal role in multisynaptic local circuit nociceptive processing in the spinal cord Collectively, these reports suggest that the reflex withdrawal response to noxious heat is not mediated through activation of NMDA receptors and subsequent production of NO and cGMP, but that the acute NMDA-produced facilitation of thermal reflexes is NMDA-, NO- and cGMP-mediated and that a sustained production of NO and subsequent activation of soluble guanylate cyclase (GC-S) in the lumbar spinal cord appears to be required for maintenance of the thermal hyperalgesia produced in persistent pain models As our knowledge and understanding of the new and intriguing class of neurotransmitters typified by NO emerges, it is likely that the next few years of pain and analgesia research will focus on the cellular events underlying mechanisms of chronic pain

MIX: a mosaic Asian anthropogenic emission inventory under the international collaboration framework of the MICS-Asia and HTAP

Abstract: . The MIX inventory is developed for the years 2008 and 2010 to support the Model Inter-Comparison Study for Asia (MICS-Asia) and the Task Force on Hemispheric Transport of Air Pollution (TF HTAP) by a mosaic of up-to-date regional emission inventories. Emissions are estimated for all major anthropogenic sources in 29 countries and regions in Asia. We conducted detailed comparisons of different regional emission inventories and incorporated the best available ones for each region into the mosaic inventory at a uniform spatial and temporal resolution. Emissions are aggregated to five anthropogenic sectors: power, industry, residential, transportation, and agriculture. We estimate the total Asian emissions of 10 species in 2010 as follows: 51.3 Tg SO2, 52.1 Tg NOx, 336.6 Tg CO, 67.0 Tg NMVOC (non-methane volatile organic compounds), 28.8 Tg NH3, 31.7 Tg PM10, 22.7 Tg PM2.5, 3.5 Tg BC, 8.3 Tg OC, and 17.3 Pg CO2. Emissions from China and India dominate the emissions of Asia for most of the species. We also estimated Asian emissions in 2006 using the same methodology of MIX. The relative change rates of Asian emissions for the period of 2006–2010 are estimated as follows: −8.1 % for SO2, +19.2 % for NOx, +3.9 % for CO, +15.5 % for NMVOC, +1.7 % for NH3, −3.4 % for PM10, −1.6 % for PM2.5, +5.5 % for BC, +1.8 % for OC, and +19.9 % for CO2. Model-ready speciated NMVOC emissions for SAPRC-99 and CB05 mechanisms were developed following a profile-assignment approach. Monthly gridded emissions at a spatial resolution of 0.25° × 0.25° are developed and can be accessed from http://www.meicmodel.org/dataset-mix .

Extraversion and Its Positive Emotional Core

Abstract: Publisher Summary This chapter focuses on the theoretical views of extraversion. Extraversion has been included as a higher-order factor in every major taxonomic scheme of personality traits that have been developed during the past 50 years. Extraversion consistently emerges as a higher-order disposition in taxonomic schemes of personality traits. Higher-order traits represent the most general level in the hierarchy of dispositions. This is the level at which personologists attempt to explain individual differences with the fewest possible and most broadly applicable dimensions. Extraversion is divided into two distinct subfactors: (1) it involves successful adaptation through satisfying interpersonal relationships, and (2) another that entails adaptation through dominance, mastery, and achievement. Theoretical conceptualizations of extraversion have gradually but, systematically evolved over the past 75 years. This evolution necessarily involves elements of both continuity and change. The continuity is largely reflected in the interpersonal components of the trait. Recent conceptualizations have also stressed the positive affective component of the trait. These models emphasize that extraverts are happy, enthusiastic, confident, active, and energetic. More fundamentally, it now appears that extraversion essentially taps individual differences in affectively rewarding performance. Compared to introverts, extraverts view themselves as more effectively and pleasurably engaged in various aspects of their lives.
