The purpose of this study is to investigate hot spots along roadways where high values of emissions are observed based upon real-world, on-road vehicle emissions measurements. A portable instrument, the OEM-2100 manufactured by Clean Air Technologies International, Inc., was used to measure on-road tailpipe emissions of carbon monoxide (CO), nitric oxide (NO), hydrocarbons (HC), and carbon diox...

Background Early phase amyloid positron emission tomography (PET) imaging is known to correlated with glucose metabolism. However, studies on the optimal time frame and SUVR cut off for early-phase PET have not been sufficiently progressed. In this study, of 18F-FBB was determined obtained. Method To determine frame, correlation between FBB FDG 67 subjects(34, Alzheimer’s disease(AD), 4 mild co...

UNLABELLED Use of hormonal contraceptives (HC) may influence total plasma concentrations of vitamin D metabolites. A likely cause is an increased synthesis of vitamin D binding protein (VDBP). Discrepant results are reported on whether the use of HC affects free concentrations of vitamin D metabolites. AIM In a cross-sectional study, plasma concentrations of vitamin D metabolites, VDBP, and t...

OBJECTIVE The objective of this study was to comparatively analyse the gastric fluid (GF) microbiota between patients with functional dyspepsia (FD) and healthy controls (HC), and to assess the effect of probiotics on the microbiota. DESIGN Twenty-four Japanese patients with FD who met the Rome III definition and 21 age-matched and gender-matched HC volunteers were enrolled. The patients with...

BACKGROUND The role of both host and pathogen characteristics in hematogenous seeding following Staphylococcus aureus bacteremia is incompletely understood. METHODS Consecutive patients with intravascular catheter-associated Staphylococcus aureus bacteremia were prospectively recruited over a 91-month period. The corresponding bloodstream isolates were examined for the presence of 35 putative...

We used the Effelsberg 100 m and IRAM 30 m telescopes to observe vibra-tionally excited cyanoacetylene (HC 3 N) in several rotational transitions toward the proto-planetary nebula CRL 618. Lines from 9 different vibrationally excited states with energies ranging up to 1600 K above ground were detected. The lines show P Cygni profiles indicating that the HC 3 N emission originates from an expand...

EGR and excess-air dilution have been investigated in a 1.5 L four cylinders gasoline direct injection (GDI) turbocharged engine equipped with prechamber. The influences of the two different technologies on performance are explored. results show that at 2400 rpm 12 bar, can adopt more aggressive ignition advanced angle to achieve optimal combustion phasing. However, has greater fuel economy tha...

OBJECTIVE To evaluate the association between lifetime exposure to shift work and blood pressure, fasting glucose (FG), anthropometric variables, body composition and heart rate variability (HRV). METHODS Male shift workers (N=438) were evaluated using principal component (PC) analysis. The variables used were: weight, body mass index (BMI), waist circumference (WC), neck circumference (NC), ...

In order to analyze the effect of hydrogen rich gas addition (HRG) on lean burn engine’s thermal efficiency and emission, an experimental research was conducted on a gasoline direct injection (GDI) engine using definite fraction of HRG. The results showed that HRG addition could significantly extend the lean operation limit, improve the engine’s lean burn ability, and decrease burn duration. HR...

To see whether the fecal coproporphyrin III:coproporphyrin I (CIII:CI) ratio (determined by HPLC) would be suitable for screening patients at risk of hereditary coproporphyria (HC), we compared such ratios with the lymphocyte coproporphyrinogen oxidase (EC 1.3.3.3) activities (COOX) in 38 subjects from one large family and two smaller families with HC. The CIII:CI ratio was normal (less than 1....
