Health-Related Quality of Life and Toxicity After Definitive High-Dose-Rate Brachytherapy Among Veterans With Prostate Cancer.

Purpose: High-dose-rate (HDR) brachytherapy (BT) is a well-tolerated and effective treatment for prostate cancer. There is limited research, however, investigating toxicity outcomes with HDRBT treatment among veterans. The objective of this study is to assess the impact on health-related quality of life (hrQOL) and physician-graded toxicities associated with HDRBT as monotherapy among veterans treated at Edward Hines, Jr.

Computed tomography versus magnetic resonance imaging in high-dose-rate prostate brachytherapy planning: The impact on patient-reported health-related quality of life.

Purpose: High-dose-rate (HDR) prostate brachytherapy uses volumetric imaging for treatment planning. Our institution transitioned from computed tomography (CT)-based planning to MRI-based planning with the hypothesis that improved visualization could reduce treatment-related toxicity. This study aimed to compare the patient-reported health-related quality of life (hrQOL) and physician-graded toxicity outcomes of CT-based and MRI-based HDR prostate brachytherapy.

Acid-Base Control of Valency within Carboranedithiol Self-Assembled Monolayers: Molecules Do the Can-Can.

We use simple acid-base chemistry to control the valency in self-assembled monolayers of two different carboranedithiol isomers on Au{111}. Monolayer formation proceeds via Au-S bonding, where manipulation of pH prior to or during deposition enables the assembly of dithiolate species, monothiol/monothiolate species, or combination. Scanning tunneling microscopy (STM) images identify two distinct binding modes in each unmodified monolayer, where simultaneous spectroscopic imaging confirms different dipole offsets for each binding mode.

Pedophilia on the Internet.

The Internet provides adults and children with a medium for professional and personal communication throughout the world. As widespread communication in cyberspace grows exponentially, the potential for Internet-related crimes, such as cyberstalkng, has accelerated. Children are particularly vulnerable to sexual predators, such as pedophiles, on the Internet.

Hate crimes on the internet.

The Internet serves as a channel for electronic communication on an international level. While communication on the Internet has grown exponentially, the proliferation of crimes in cyberspace has become rampant. Hate crimes, in particular, have become increasingly prevalent on the Internet.
