In this work, we modify the multisite Stern-Volmer (MSV) equation for fitting fluorescence titration curves. Under the condition of a static quenching mechanism, the MSV postulates an underlying 1:1 fulvic acid (FA)/copper coordination ratio at multisites. Approximates of six fitting parameters characterize the stability constants (K1 and K2) of FA ligands with Cu2+, micromolar ligand site conc...

This pathway provides guidance for the imaging of adult patients with right iliac fossa pain or suspected acute appendicitis, as well as the many mimickers of appendicitis.

Murine sarcoma virus-associated protein kinases that bind to actin have been purified by affinity chromatography on actin coupled to Sepharose. Heat inactivation studies showed the presence of thermolabile enzyme activity in pseudotypes containing a temperature-sensitivity mutant of murine sarcoma virus (MSV) but not in two independent wild-type MSV pseudotypes. Studies with Sephadex G-75 colum...

Ant and homopteran mutualisms are complex because they depend on the behavior, abundance, and predation levels of both insect species. Because homopteran populations are critically impacted by these seasonally varying factors, it is important to measure the population dynamics of ant-tended homopterans outside of the laboratory. In this study, we develop a new method for documenting the populat...

Anampses viridis Valenciennes 1840 is known from only three specimens collected from Mauritius, and despite intensive sampling, the species has not been seen or reported since it was originally described. This apparent failure to 'rediscover' A. viridis at Mauritius has led to speculation that it is extinct, and the species has been widely cited as an example of a marine fish extinction. Far fr...

The 2011 Great East Japan Earthquake led to a subsequent nuclear accident at the Fukushima Daiichi Nuclear Power Plant. In its wake, we sought to examine the association between external radiation dose and thyroid cancer in Fukushima Prefecture. We applied a cross-sectional study design with 300,476 participants aged 18 years and younger who underwent thyroid examinations between October 2011 a...

This pathway provides guidance on the imaging of adult patients with a focal liver lesion discovered incidentally on imaging for unrelated indications, who have no history of malignancy or risk factors for hepatocellular carcinoma.

The response of the passive photodosimeter with halide film characterized by a high optical density of about 0.550 ± 0.007 was analysed on dose ranges, taking into consideration the filters of the dosimetric badge, and finally compared with the thermoluminescent dosimeter (TLD). In this respect the dosimeters were exposed to a Cs 137 calibration radioactive source at different points within (0....

induced solid tumors in mice, rats, and hamsters. These virus isolates are now known as MSV-H3 and MSV-M. The histol ogy of these tumors has been described extensively by a number of workers (4, 27, 35). Soehner and Dmochowski (32) have recently reported the induction of osteosarcomas in rats and hamsters by both MSV-M and MSV-H. They have also reported the cell-free transmission of these tumor...
