In addition, POSS-NH(2)/BT hybrids also show good thermal and thermo-oxidative stability compared with BT resin. All these differences in macroproperties are attributed to the difference in chemical structure between POSS-NH(2)/BT hybrids and BT resin. (C) 2010 Wiley Periodicals, Inc.

“Membrane technology is broadly applied in the medical field. The ability of membranous systems to effectively control the movement of chemical entities is pivotal to their signi. cant potential for use in both drug delivery and surgical/medical applications. An alteration in the physical properties of a polymer in response to a change
in environmental conditions is a behavior that can be utilized to prepare ‘smart’ drug delivery systems. Stimuli-responsive or ‘smart’ polymers are polymers that upon exposure to small changes in the environment undergo rapid changes in their microstructure. A stimulus, such as a change learn more in pH or temperature, thus serves as a trigger for the release of drug from membranous drug delivery systems that are formulated from stimuli-responsive polymers. This article has sought to review the use of stimuli-responsive polymers that have found application in membranous drug delivery systems.
Polymers responsive to pH and temperature have been extensively addressed in this review since they are considered the most important stimuli that may be exploited for use in drug delivery, and biomedical applications such as in tissue engineering. In addition, dual-responsive selleck inhibitor and glucose-responsive membranes have been also addressed as membranes responsive to diverse stimuli.”
“Skin cancer is the most common form of cancer in the US, and an important public health concern both in the US
and throughout the world. Given high incidence rates among young adults and the large number of deaths, skin cancer has the potential to result in significant years of potential life lost (YPLL) and lost productivity. The purpose of this study was to systematically review the published literature on the YPLL and the value of productivity loss from morbidity and premature mortality resulting from melanoma and non-melanoma skin cancer (NMSC).
Employing pre-defined search terms and inclusion/exclusion p38 MAPK activity criteria, systematic searches were conducted in MEDLINE, EMBASE, CINAHL and Econlit. We selected studies that measured the societal burden of melanoma and NMSC through estimating either the YPLL and/or the indirect costs.
We identified 16 relevant studies meeting our criteria, six were from the US and ten were from other industrialized countries; ten of the studies reported results on YPLL, eight on mortality costs and five on morbidity costs. Some studies reported results in more than one category.
From each eligible article and report, we extracted detailed information on the study population/country, study design, data analysis methods and study results.
