Soon after the atomic theory was established, it was found that the plant uses as sources of food not only the air and water, but also different constituents of the soil, dissolved in the soil moisture—the mineral nutrients. Ashes of different...
QSOs, providing distant, luminous sources of radiation, provide a means to detect gas by absorption in the interstellar and intergalactic medium. Of particular interest to astronomers studying metal line systems in lines of sight to QSOs are the...
Arrhythmia; Heart--Diseases; Heart beat; Heart conduction system
Introduction: Hyperhomocysteinemia (HHcy) is a pathological condition characterized by excessive levels of plasma homocysteine (Hcy). Patients with HHcy are reported to be at risk for arrhythmias like atrial fibrillation and sudden cardiac death...
The purpose of this dissertation was to demonstrate that a new method of direct intracellular energy delivery was effective in maintaining viability of in vitro Human Umbilical Vein Endothelial Cells (HUVECs) when exposed to chemical ischemia for...
Few previous studies have compared microbial communities in subterranean and surface environments. Chemical analyses used to characterize the surface and cave microbial environments indicated limited exchange between surface and subsurface waters....
Conducting polymers; Polymers in medicine; Myocardium
Hydrophilic and conductive characteristics in polymers are mutually exclusive of each other. Hydrophilic polymer properties allow absorption of water up to several magnitudes above their dry weight. However, due to their molecular structure, they...
View of giant stalactites inside Mammoth Cave at The Altar. Text on verso: "In the foreground is a cluster of columns called the Altar, at which a romantic marriage took place between two parties whose union on the face of the earth was...
The inherited bone marrow failure syndromes (IBMFS) encompass a heterogeneous collection of rare disorders characterized by hematological abnormalities, generalized growth delays, and an increased incidence of malignant transformation. These...
Copper--Physiological effect; Copper in the body; Heart--Hypertrophy
Previous studies have shown that copper (Cu) supplementation at physiologically relevant levels reverses cardiac myocyte hypertrophy induced by phenylephrine (PE), and that this effect was VEGF-dependent. Yet, the amount of VEGF in the media was...
Drug resistance in microorganisms; Salmonella typhimurium
Salmonella enterica serovar Typhimurium is an enteric pathogen capable of infecting
a wide range of hosts. The manner in which this pathogen is able to interact with its
host is difficult to define, as is the case with most microbes. Through the...
Aim. The efficacy of ridge preservation procedures using grafting materials and barrier membranes has been well established in the literature. However, the loss of horizontal width even with the utilization of intrasocket only guided bone...
The Technical Advisory Group (TAG) of the Innovative Treatment Remediation Demonstration Program (ITRD) made technology recommendations after reviewing thirty in situ remediation technologies for implementation at the Paducah Gaseous Diffusion...
III-nitrides (InN, GaN, AlN) are some of the most promising materials for making blue light emitting diodes (LED), blue laser diodes (LD) and high power, high temperature field effect transistors (FET). Current techniques produce GaN films with...
A growing interest has manifested itself within the past two or three years in "phytin" and "phytic acid", and in some of the compounds of the latter. Posternak first isolated this substance from the seeds of the red fir,...
Circulating nucleated cell populations found in whole blood, including both white blood cells (leukocytes) and endothelial cells, provide an ideal platform for studies seeking to understand the disease processes for development of drugs and...
Aim. To compare two techniques of ridge preservation using a mineralized cancellous particulate allograft to a mineralized cortical particulate allograft plus an acelluar dermal matrix barrier membrane using clinical and histologic data to assess...
Indians of North America--Kentucky--Bullitt County--Antiquities; Excavations (Archaeology)--Kentucky--Ashworth Rockshelter site; Ashworth Rockshelter site (Ky.)
Reinvestigation of a National Register property, the Ashworth Rockshelter (15BU236), northeast of Shepardsville, Bullitt Co., Kentucky, revealed stratified Early Archaic through Mississippian components (ca. 7900 B.C.-1500 A.D.). Primary occupation...
Energy independence requires that the nation reduce its dependence on foreign oil imports. This can be achieved through electrification of transportation vehicles if proper battery technology can be developed. In addition, the renewable energy...
Aim. Differences in the healing of demineralized and mineralized allografts have been reported but their significance has not been evaluated in ridge preservation studies. The primary aims of this study were to compare ridge preservation using a...
Wounds and injuries--Treatment; Drug delivery systems
Wounds care and management is one of the most basic needs in the medical setting. Burn wounds, trauma wounds, pressure ulcers and bedsores are just some of the many types of wounds that need to be treated quickly and efficiently. Take for instance...
