Zicao is a traditional Chinese herbal medicine that has been used for the topical treatment of wounds in the form of oil-based ointment for several hundred years. To overcome the disadvantages of oil-based ointment such as irritation, discomfort, and difficulty in cleaning, this study developed a water-based topical formulation of Zicao. An ethanol extract of Zicao was included in 2-hydroxypropyl-β-cyclodextrin (HP-β-CD) to form a water-soluble Zicao-HP-β-CD complex. The formation of the Zicao-HP-β-CD complex was determined using LC-MS, 1 H NMR, ROSEY, and solubility analysis...

REVIEW
Paul Jung, Boris D Lushniak
As some preventive medicine physicians have been denied medical licenses for not engaging in direct patient care, this paper attempts to answer the question, "Do preventive medicine physicians practice medicine?" by exploring the requirements of licensure, the definition of "practice" in the context of modern medicine, and by comparing the specialty of preventive medicine to other specialties which should invite similar scrutiny. The authors could find no explicit licensure requirement for either a certain amount of time in patient care or a number of patients seen...

Jean-Baptiste Coty, Christine Vauthier
The nanotechnology revolution offers many expectations for the improvement of medicine treatments. At present, nanomedicine (NM) development is hampered by methodological barriers for a better characterization and a wider understanding of their in vivo behavior. While regulatory agencies setup guidelines to support NM translation from bench to bedside, the gap is still hardly overcome by main nanomedicines. One lever for filling this gap is a better characterization, thus increasing the global knowledge about the NM itself but also validate the confidence in terms of batch to batch reproducibility of such complex nano-objects...

Travellers with recognised disabilities or the dis-ability to function as required during a trip have been overlooked in the travel medicine literature. This paper provides a starting point for further discussion and research into this neglected traveller population. In contrast, tourism research has explored travel with a disability for some time in order to understand the travellers' needs and to improve services accordingly. The contemporary bio-psycho-social understanding of disability serves as the framework for exploring motivations to travel as well as barriers, such as inter and intrapersonal, economic, structural and attitudinal obstacles...

The skeleton is the most common metastatic site in patients with advanced cancer. Pain is a major healthcare problem in patients with bone metastases. Bone-seeking radionuclides that selectively accumulate in the bone are used to treat cancer-induced bone pain and to prolong survival in selected groups of cancer patients. The goals of these guidelines are to assist nuclear medicine practitioners in: (a) evaluating patients who might be candidates for radionuclide treatment of bone metastases using beta-emitting radionuclides such as strontium-89 ( 89 Sr), samarium-153 ( 153 Sm) lexidronam ( 153 Sm-EDTMP), and phosphorus-32 ( 32 P) sodium phosphate; (b) performing the treatments; and...
