Nearshore Gulf ecosystem : diagram and documentation

This report has been prepared to accompany and to provide supporting documentation for the ecological system diagram of the Nearshore Gulf. The ecosystem diagram concept and its application to the assessment of activities in the coastal zone has been documented in technical papers of the Texas Coastal Management Program. In particular, Technical Paper #12 describes the theory, methods of construction and examples of diagrams for other coastal ecosystems.Prepared for the General Land Office of Texas, Bob Armstrong, commissionerAugust 31, 1979Marine Scienc

Sportfishing creel census pilot study

The sportfishing creel census project was originated to obtain information relating to the use of the Corpus Christi Bay area for sportfishing, the amount of fish caught and other environmental information relating to the total productivity cycles of the bay system. The Census is to be conducted during the summer months of June, July and August 1974 and the pilot study was made during August 1973. The total catch will be used in a current project to assess carbon, nitrogen, phosporous input and output to the bay system.March 15, 1974To The Lower Nueces River Water Supply DistrictMarine Scienc

Water quality of Texas bays (nutrients, trace elements and toxic compounds)

This manuscript is designed to compare the nutrient balances and trace element significance in Texas Bays and Estuaries. The task of assigning water quality criteria in all estuarine waters rests with the federal Environmental Protection Agency. However, the Texas Bays and Estuaries represent a unique range of environments of the U.S. Coast that stand alone and therefore must be assigned standards appropriate to the environment. Therefore we have compared several Texas Bays relative to nutrients and trace elements through an analysis of data from our files, a life history data bank from literature survey, a study of the Corpus Christi area, personal communication with a wide range of individuals and information from the Texas Water Quality Board, Texas Water Development Board, the U.S. Geological Survey and the State Health Department.May 30, 1974Taken in part from a report on Development of Biological Criteria, Establishment of Guidelines for Texas Coast Management IAC-(74-75)-0685 NSF RANN-61-34870xMarine Scienc

CLINICAL EVALUATION OF NOVEL METHODS FOR EXTENDING MICRONEEDLE PORE LIFETIME

Microneedles are a minimally invasive method for delivering drugs through the impermeable skin layers, and have been used to deliver a variety of compounds including macromolecules, vaccines, and naltrexone. Microneedles can be applied to the skin once, creating micropores that allow for drug delivery into the underlying circulation from a drug formulation. The utility of this technique, however, is blunted by rapid micropore closure. This research project sought to: 1) characterize micropore lifetime and re-sealing kinetics, and 2) prolong micropore lifetime via inhibition of the skin’s barrier restoration processes. Impedance spectroscopy was used as a surrogate technique in animals and humans to measure micropore formation and lifetime. A proof of concept study in humans, using impedance spectroscopy, demonstrated that diclofenac (a topical anti-inflammatory) applied to microporated skin resulted in slower re-sealing kinetics compared to placebo, in agreement with previous animal studies. The clinical feasibility of prolonging micropore lifetime with diclofenac was confirmed via 7-day delivery of naltrexone through microneedle treated skin in humans (compared to 72 hour delivery with placebo). Lastly, naltrexone gels with calcium salts were applied to microneedle treated skin (hairless guinea pigs) to restore the altered epidermal calcium gradient; this method did not significantly extend micropore lifetime
