Sharp wave-associated synchronized inputs from the piriform cortex activate olfactory tubercle 1 neurons during slow-wave sleep 2 3 Kimiya Narikiyo Abstract 18 During slow-wave sleep, anterior piriform cortex neurons show highly synchronized discharges that 19 accompany olfactory cortex sharp waves (OC-SPWs). The OC-SPW-related synchronized activity of 20 anterior piriform cortex neurons travel...
An intensive observation of organic carbon (OC) and elemental carbon (EC) in PM10 and gaseous materials (SO2, CO, and O3) was conducted continuously to assess the characteristics of wintertime carbonaceous aerosols in an urban area of Beijing, China. Results showed that the averaged total carbon (TC) and PM10 concentrations in observation period are 30.2 +/- 120.4 and 172.6 +/- 198.3 microg/m3,...
We use a global 3-D model simulation of elemental carbon (EC) and organic carbon (OC) aerosols to interpret year-round observations for 1998 at a network of 45 U.S. sites (IMPROVE) and from there to better quantify the natural and anthropogenic U.S. sources of these aerosols. Our resulting best estimate of 1998 sources in the contiguous United States are 0.60 Tg yr EC and 0.52 Tg yr OC from fos...
STUDY OBJECTIVE To assess age specific incidence and mortality of stroke, acute myocardial infarction (AMI), and idiopathic venous thromboembolism (VTE) associated with use of modern low dose combined oral contraceptives (OCs) and the interaction with smoking. DESIGN Hospital-based case-control study. SETTING Hospitals in Oxford region in the United Kingdom, which covered a defined populati...
Testis maturation, germ cell development and function of sperm, are related to lipid composition. Phosphatidylcholines (PCs) play a key role in the structure and function of testes. As well, increases of polyunsaturated fatty acids (PUFA) and highly unsaturated fatty acids (HUFA), especially arachidonic acid (ARA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA) are essential for ma...
Carbon storage capacity of semi-arid grassland soils and sequestration potentials in northern China.
Organic carbon (OC) sequestration in degraded semi-arid environments by improved soil management is assumed to contribute substantially to climate change mitigation. However, information about the soil organic carbon (SOC) sequestration potential in steppe soils and their current saturation status remains unknown. In this study, we estimated the OC storage capacity of semi-arid grassland soils ...
Caffeine consumption increases the urinary excretion of calcium and other minerals. Factors that affect caffeine metabolism such as steroid hormones may modify this effect. The purpose of this study was to evaluate the influence of oral contraceptive (OC) use on the 4-h urinary excretion of calcium, phosphorus, magnesium, zinc, sodium, potassium and caffeine metabolites in response to a high ca...
Svanberg, A. 2012. Mucositis Prevention for Patients Receiving High Dose Chemotherapy and Stem Cell Transplantation.: Preventive Strategies There is Always More to do.. Acta Universitatis Upsaliensis. Digital Comprehensive Summaries of Uppsala Dissertations from the Faculty of Medicine 798. 57 pp. Uppsala. ISBN 978-91-554-8438-5. The aim of this thesis was to investigate oral cryotherapy (OC) a...
BACKGROUND Cigarette smoking and oral contraceptive (OC) use have been associated with cervical neoplasia, and the combination of smoking and OC use could influence cervical carcinogenesis. We aimed to assess the joint effect of smoking and OC use on the risk of cervical intraepithelial neoplasia (CIN). METHODS From a cohort of human papillomavirus-positive subjects recruited from 6 hospitals...
Samples from Hong Kong, China, were analyzed for organic carbon (OC), elemental carbon (EC), and total carbon (TC) by three thermal protocols (low-temperature IMPROVE and high-temperature STN and NIOSH) and two optical monitoring methods: reflectance and transmittance. Good agreement (+/-10%) for TC among the three protocols was observed for sample loadings of 1-55 microg m(-3). The two protoco...
