Amelogenesis imperfecta is a set of hereditary defects representing mainly the development defects of enamel without the presence of whole-body symptoms. Developmental disorders can manifest a complete absence of enamel, which is caused by improper differentiation of ameloblasts. This article describes the diagnosis and treatment of a patient with(More)
Hepatic clearance of long-chain fatty acids is substantially faster in females than in males, a fact that may underlie known gender-related differences in lipoprotein metabolism and associated disease states. To further investigate the transport steps responsible for this difference, we used a novel method combining multiple-indicator dilution and(More)
We evaluated a potential index for quantifying wetland floristic quality, based on the Floristic Quality Assessment Index (FQAI) developed and tested in other regions of the United States. Principal reasons for this study were 1) FQAI is based on plant species’ coefficients of conservatism, which are unavailable for most of the world and 2) FQAI value(More)
The goal of periodontal treatment in not only the stabilization of disease but also the regeneration of the destructed tissue. In the past few years various procedures have been created to achieve this. The guided tissue regeneration is a surgical procedure developed on the basis of experimental studies. It enables the creation of periodontal tissues(More)
Condensing osteitis is defined as pathologic growth of maxillomandibular bones characterized by mild clinical symptoms. The bone thickening reflects the impaired bone rearrangement in response to mild infection of dental pulp. This clinical study describes case reports of patients sent to us with radiological findings and clinical examination that failed to(More)
Stem cells play pivotal role in the development of tissues and organs, as well as they maintain homeostasis and integrity of multicellular organisms. Human dental pulp-derived stem cells are capable of differentiation into osteoblasts, odontoblasts, adipocytes and neuronal-like cells and can have potential use in tissue regeneration. The aim of this study(More)
In situ decomposition of above and belowground plant biomass of the native grass species Andropogon glomeratus (Walt.) B.S.P. and exotic Imperata cylindrica (L.) Beauv. (cogongrass) was investigated using litter bags over the course of a 12 month period. The above and belowground biomass of the invasive I. cylindrica always decomposed faster than that of(More)
A new custom-built duo spectrometer has been commissioned for fast localized Doppler measurements of plasma ions in the Madison Symmetric Torus. The instrument combines very high optical throughput (transmission efficiency of 6% and etendue of 0.80 mm(2) sr divided into two simultaneous measurements) with good resolution (lambda/Deltalambda=5600). The(More)
Improved confinement has been achieved in the MST through control of the poloidal electric field, but it is now known that the improvement has been limited by bursts of an edge-resonant instability. Through refined poloidal electric field control, plus control of the toroidal electric field, we have suppressed these bursts. This has led to a total beta of(More)
