The History & Status Of The Impact Act, Lisa M. Grabert

College of Nursing Faculty Research and Publications

The ability to effectively study and compare Medicare patients—and the cost and outcomes associated with their care—has long been, and continues to be limited, by the lack of readily comparable, patient-level, clinical data. This is due primarily to Medicare’s reliance and use of historically-developed, and limited administrative data—data derived from traditional insurance claims records, not patient treatment records. Critics of this situation have long called for the development of more comprehensive patient-level and clinically focused data, particularly in support of increasing efforts to compare and promote higher quality of care in the system.

Calls to develop more comprehensive patient outcome …

Vasopressin Regulates Daily Rhythms And Circadian Clock Circuits In A Manner Influenced By Sex, Kayla Rohr, Adam Telega, Alexandra Savaglio, Jennifer A. Evans

Biomedical Sciences Faculty Research and Publications

Arginine vasopressin (AVP) is a neurohormone that alters cellular physiology through both endocrine and synaptic signaling. Circadian rhythms in AVP release and other biological processes are driven by the suprachiasmatic nucleus (SCN) of the anterior hypothalamus. Loss of vasopressin signaling alters circadian behavior, but the basis of these effects remains unclear. Here we investigate the role of AVP signaling in circadian timekeeping by analyzing behavior and SCN function in a novel AVP-deficient mouse model. Consistent with previous work, loss of AVP signaling increases water consumption and accelerates recovery to simulated jetlag. We expand on these results to show that loss …

Bioresorbable Composite Polymeric Materials For Tissue Engineering Applications, Sakineh Hajebi, Saeed Mohammadi Nasr, Navid Rabiee, Mojtaba Bagherzadeh, Sepideh Ahmadi, Mohammad Rabiee, Mohammadreza Tahriri, Lobat Tayebi, Michael R. Hamblin

School of Dentistry Faculty Research and Publications

This review covers the development of bioresorbable polymeric composites for applications in tissue engineering. Various commercially available bioresorbable polymers are described, with emphasis on recent bioresorbable composites based on natural and synthetic polymers. Bioresorbable polymers contain hydrolyzable bonds, which are subjected to chemical degradation via either reactive hydrolysis or enzyme-catalyzed active hydrolysis. For synthetic polymers, chemical hydrolysis is the most important mode of degradation. The degradation rate can be controlled by varying the molecular weight and crystallinity. Examples of bioresorbable polymers are: polyurethane, poly(D,L)lactide, poly(lactic-co-glycolic) acid, poly(α-hydroxy acids), cross-linked polyester hydrogels, poly(orthoesters), polyanhydrides and polyethylene glycol.
