Abstract:: Chitosan based hemorrhage control dressings provide effective external hemorrhage control while having few side effects. Known residual contaminants present in chitosan formulations include endotoxins and proteins known to stimulate gene expression in the liver. This study investigated gene expression in the liver using rat bio-compatibility models to gain knowledge regarding...

Abstract:: Pactamycin, a complex aminocyclitol compound produced by Streptomyces pactum, has significant antibiotic, antitumor, and antiplasmodial activity. However, this natural product has not been developed for clinical use due to its high cytotoxicity. Modulation of its biological properties by chemical synthesis has been difficult due to its complex chemical structure. Therefore,...

Abstract:: When characterizing the processes that shape ecosystems, ecologists increasingly use the unique perspective offered by repeat observations of remotely sensed imagery. However, the concept of change embodied in much of the traditional remote-sensing literature was primarily limited to capturing large or extreme changes occurring in natural systems, omitting many more...

Creator:: Gray, Andrew N. and Whittier, Thomas R.
Abstract:: The National Forest System (NFS) of the United States plays an important role in the carbon cycle because these lands make up a large proportion of the forested land in the country and commonly store more wood per unit area than other forest ownerships. In addition to sustaining natural resources,...

Abstract:: The Horseshoe Gulch area includes 16 square miles in the Eastern Paleozoic Belt of the Klamath Mountains geologic province north of Callahan, California. Fossiliferous Late Ordovician and Silurian limestones and unfossiliferous greywackes, arkoses, shales, mudstones, schists, and phyllites, and other terrigenous clastic rocks are exposed in a broad fault zone...

Abstract:: Alcoves in some river systems are cooler than the mainstem of the river and provide thermal refugia for aquatic species. An energy balance and sensitivity analysis on 3 alcoves in the Willamette River, Oregon indicate that alcove size and alcove flux determine the degree to which meteorological conditions affect the...

Creator:: Dail, David (David Andrew)
Abstract:: Obtaining accurate estimates of animal abundance is made difficult by the fact that most animal species are detected imperfectly. Early attempts at building likelihood models that account for unknown detection probability impose a simplifying assumption unrealistic for many populations, however: no births, deaths, migration or emigration can occur in the...

Creator:: Valentine, Beth A., Bildfell, Robert J., and Dunn, Andrew J.
Abstract:: Tumours arising from the dorsal surface of the tongue occurred in 3 horses from 14-23 years of age. Tumours were surgically excised at a referral hospital (1 case) and on the farm (2 cases) and submitted for histopathology. All tumours were multilobular and composed of vaguely nested, bland, oval to...
