Date of Report: July 2010 EPA Agreement Number: RD-83283501 Title: An Instrument for Real Time Speciation of Water Soluble Tracers in Atmospheric Particulate Matter Investigators: Rodney J. Weber (PI Georgia Tech), James J. Schauer (Co-PI, UWMadison), Martin Shafer (Co-PI, UW-Madison) Institution: Georgia Institute of Technology Research Category: Continuous Measurement Methods For Particulate ...
Phosphatidylinositol (PI) 3-kinase plays an important role in the signalling of cell growth. We previously purified two types of PI 3-kinase from bovine thymus, a monomer from (PI 3-kinase I) and a heterodimer form (PI 3-kinase II) [Shibasaki, Homma and Takenawa (1991) J. Biol. Chem. 266, 8108-8114]. Here we examine the properties of these purified PI 3-kinases. Both PI 3-kinases were inhibited...
We report magnetic and electrical measurements of Nb Josephson junctions with strongly ferromagnetic barriers of Co, Ni, and Ni80Fe20 (Py). All these materials show multiple oscillations of critical current with a barrier thickness implying repeated 0-pi phase transitions in the superconducting order parameter. We show, in particular, that the Co barrier devices can be accurately modeled using ...
The pulvinar of primates, which connects with all visual areas, has been implicated in visual attention and in control of eye movements. Recently, five separate neurochemical subdivisions of a region termed the inferior pulvinar complex have been identified in monkeys (Gray et al. [1999] J Comp Neurol 409:452-468; Gutierrez et al. [1995] J Comp Neurol 363:545-562), and comparable subdivisions h...
objective: an association between poor oral health and chronic lung disease has recently been reported. the purpose of this study was to explore this potential association between asthma and periodontal disease. materials and methods: this is a descriptive case controlled study. the samples were selected from patients referred to respiratory disease clinic in a hospital in tehran, iran. the stu...
Photosynthesis-irradiance (PI) curves are extensively used in field and laboratory research to evaluate the photon-use efficiency of plants. However, most existing models for PI curves focus on the relationship between the photosynthetic rate (Pn) and photosynthetically active radiation (PAR), and do not take account of the influence of environmental factors on the curve. In the present study, ...
High concentrations of heavy metals in street dust are considered to be a serious risk to the human health and the environment. In this study, 30 dust samples were collected from the pavements in the main streets of Abadan to determine the level of pollution of heavy metals in the street dust. Heavy metal concentrations were analyzed by inductively coupled spectroscopy (ICP-OES) method. The lev...
Topological indices are numerical parameters of a graph which characterize its topology. In this paper the PI, Szeged and Zagreb group indices of the tetrameric 1,3–adamantane are computed.
High concentrations of orthophosphate (Pi) inhibited CO(2)-dependent O(2) evolution and prevented the inactivation of glucose-6-P dehydrogenase by light in intact spinach and barley chloroplasts. Addition of glycerate-3-P to chloroplasts inhibited by Pi in the light, induced O(2) evolution and caused rapid inactivation of glucose-6-P dehydrogenase. The activity of phosphofructokinase detected i...
Background and purpose: Osteoporosis and periodontitis are two diseases associated with bone loss and are common among postmenopausal women. There are many contradictory results on the effect of osteoporosis on periodontal tissue. This study aimed to determine the association between osteoporosis and periodontal status in postmenopausal women. Materials and methods: This cross-sectional study...
