Modified Hbs are being developed as "blood substitutes," but intravascular injection of diaspirin cross-linked Hb (DBBF-Hb) can produce venular leakage. Hb toxicity may arise from reactive oxygen species, so the antioxidant sodium selenite (Na(2)SeO(3)) was used in an attempt to reduce leak formation. In anesthetized Sprague-Dawley rats, one-half of which received 2 x 10(-6) g/ml Na(2)SeO(3) in...

This paper provides an empirical link between the expected cost of equity and firms’ Seasoned Equity Offerings activities, using a novel measure of forward-looking cost of equity. There is a negative impact of expected cost equity on SEO likelihood and amount of proceeds, exists on both market and firm level. Empirical evidence suggests that the negative SEO announcement effect and post-SEO lon...

The adsorption of selenite ions (SeO~-) from a dilute aqueous solution onto a freshly-cleaved calcite (1014) surface was studied with the X-ray standing wave (XSW) technique. The complex ion SeO zis found to selectively adsorb at the CO~ site via ionic exchange, forming a two-dimensional solid-solution of the form Ca(SeO3)x(CO3) 1 x at the interface. The calcite (1014), (0006) and (1120) Bragg ...

This paper examines the relation between the Seasoned Equity Offering (SEO) announcement effect and earnings timeliness. I predict that firms with greater earnings timeliness tend to have less information asymmetry between managers and investors, thus decreasing the magnitude of the price drop at the SEO announcement. As anticipated, I find that SEO negative announcement effect varies inversely...

Because of the difficulty in multi-dimensional matching and missing variables, investigation of long-run stock performance after major corporate events has been plagued by the “bad model problem”. This study contributes to the literature by implementing the propensity score estimator which is able to match firms in multiple dimensions simultaneously, and illustrate this methodology in the conte...

dpph radical-scavenging activity of the bene hull oil (bho), sesame oil (seo), rice bran oil (rbo), the oils' methanolic (ch3oh/h2o, 80:20 v/v) or hexane extracts, and their unsaponifiable matters fraction were measured and compared with each other. as a radical-scavenger, seo was significantly stronger than rbo and bho, respectively. unlike bho and rbo, the unsaponifiable (usm) fraction of the...

Objective A smartphone-enabled otoscope (SEO) can capture tympanic membrane (TM) images. We sought to compare a SEO to microscopic otoscopy in the detection and evaluation of TM pathology in an otology/neurotology practice. Study Design Prospective single-site study in adults presenting over a 3-month period. Setting Neurotology clinic within a tertiary care academic medical center. Subjects an...
