BACKGROUND: There has been strong recent interest in the association between serum ferritin concentrations and increased risk of cardiovascular events. Surplus nutrition and convenience-seeking behavior has contributed to emergence of an increasingly obese population, with a concurrent increase in the prevalence of cardiovascular diseases. To date, few studies have specifically examined the association between serum ferritin and aortic stiffness in healthy populations, thus we ...

Restriction digestion fragments of DNAs extracted from 14 representative strains of Saccharomonospora azurea, “Saccharomonospora caesia,” Saccharomonospora cyanea, Saccharomonospora glauca, and Saccharomonospora viridis and six “Saccharomonospora”-like isolates were separated by electrophoresis, Southern blotted onto nylon membranes, and hybridized by using two rRNA gene probes cloned from Streptomyces griseus subsp. griseus KCTC 9080. The following four restriction endonucleases were ...

A high-quality amine-functionalized metal organic framework, amino-MIL-53(Al), was synthesized by a solvothermal method in DMF and evaluated as an adsorbent for CO2/N2 separation both at ambient and high-pressure conditions. The textural properties of the amino-MIL-53(Al) gradually improved as the synthesis time was extended, and the optimized sample showed excellent crystallinity accompanied by a high surface area (937m2 g−1) and large pore volume (0.53cm3 g−1), both of which being ...

Urinary tract infections are common clinical problems in children, even though lots of treatment strategies have been tried. Many studies of the application of probiotics for urinary tract infection in female adults exist, but there is a lack of studies in children. The aims of this study were to screen probiotic strains for inhibiting the uropathogens in vitro, to find candidates for in vivo study. Nine strains of E. coli were isolated from children with urinary tract infection and six ...

Twenty-one strains of Saccharomonospora azurea, Saccharomonospora cyanea, Saccharomonospora glauca, Saccharomonospora viridis, and “Saccharomonospora caesia” were examined to evaluate the discriminatory value of 16S ribosomal DNA (rDNA) fingerprints. The 16S rDNAs were amplified by PCR by using oligonucleotide primers complementary to 16S rRNA genes. A restriction fragment length polymorphism (RFLP) analysis of the 16S rDNAs was performed with SmaI and MluI. The four validly described ...

Familial control of television viewing in light of the introduction of the videocassette recorder (VCR) was examined by: asking sets of parents and children about their use of VCRs and television, determining differences in these perceptions, and relating family demographics to use and control. In‐home interviews with 110 families found agreement on who chooses the programs to be watched. Some differences were noted, however, between parents’ and children's perceptions of how the viewing ...

Using 256 TARP recipients, I find that markets negatively react to the news on limiting executive compensations. Although investors react quite positively for the initial announcement of TARP on October 14, 2008, other announcements regarding compensation regulation including a strict $500,000 salary cap are perceived as bad news in the market. The results are more supportive of the managerial talent hypothesis, which implies that investors are concerned about losing talented executives ...

BACKGROUND/OBJECTIVES: This study was designed to investigate the improvement effect of white ginseng extract (GS-KG9) on D-galactosamine (Ga1N)-induced oxidative stress and liver injury.

SUBJECTS/METHODS: Sixty Sprague-Dawley rats were divided into 6 groups. Rats were orally administrated with GS-KG9 (300, 500, or 700 mg/kg) or silymarin (25 mg/kg) for 2 weeks. The rats of the GS-KG9- and silymarin-treated groups and a control group were then intraperitoneally injected Ga1N at a ...

Nonalcoholic fatty liver disease (NAFLD) is very prevalent worldwide and is associated with insulin resistance and metabolic syndrome. Stress is a physiological and biological response to maintain homeostasis of the body against stressors while severe stress response is an important contributor to various illnesses, including metabolic syndrome and brain disorders. We have evaluated the effects of intermittent restraint stress on NAFLD in a high-fat diet (HFD)-fed mouse model. C57/BL6 ...

Limiting executive compensation through a salary cap has emerged as one of the latest global governance initiatives. We investigate the effectiveness of a form of an executive salary cap system and find that only firms with a high level of effective external monitors set their salary cap significantly sensitive to firm performance (cap-performance sensitivity). The difference between the salary cap and actual pay (the gap) varies by the level of monitoring. Therefore, the existence of an ...

Stock options are one of the most widely used equity-based compensation mechanisms to mitigate misalignment between managers’ and shareholders’ interests. And yet, it is sometimes suspiciously used as a method of extracting shareholders’ wealth to managers (Bebchuk et al., 2009). The typical ways to do so is using opportunistic timing such as backdating, spring-loading, etc. As shown in Bebchuk et al. (2010), opportunistic timing of option grants increases the incidence of lucky grants, ...

We examine whether foreign investors impact corporate governance by analyzing the relation between foreign share ownership and pay-performance sensitivity. While the extant literature has examined the impact of foreign ownership, the evidence for emerging markets is limited. We test our hypotheses using a sample of Korean firms, an emerging market with unique characteristics. We find that firms with higher foreign share ownership demonstrate significant pay-performance sensitivity while ...
