| Land is a natural resource that is valued for many reasons. Farmers utilize land to earn their livelihood and as a store of wealth for future retirement. Potential rural residents have increasingly sought open space for a home site and pursuit of a lifestyle. Developers seek financial opportunities to invest in and develop it for non-farm uses. Recreational needs such as hunting are often met through use of land. For some, land is viewed as an investment and a hedge against inflation. This myriad of demands for land combined with its fixed supply continually alters its market price, which is a monetary measure of its perceived value. |

| This report evaluates the U.S. and world sugar markets for 2008-2018 using the Global Sugar Policy Simulation Model. This analysis is based on assumptions about general economic conditions, agricultural policies, population growth, weather conditions, and technological changes. Both the U.S. and world sugar economies are predicted to remain stable over the next ten years in spite of the 2007-08 surge in world oil prices. That increase in price caused an increase in the conversion of sugar into ethanol in Brazil, while other exporting countries increased their production in response to those higher prices. Sugar prices returned to normal levels in 2008. World demand for sugar is expected to grow at a similar rate to world supply, resulting in Carribean... |

| This report evaluates the U.S. and world wheat markets for the 2008-2018 period using the Global Wheat Policy Simulation Model. This analysis is based on a series of assumptions about general economic conditions, agricultural policies, weather conditions, and technological change. Both the U.S. and world wheat economies are predicted to remain relatively healthy for the next ten years. World demand for both common and durum wheat are expected to remain strong. The price levels in 2007 and 2008 will not be maintained in 2009 and future because increased wheat and corn production in 2008 and reduced demand for corn for ethanol production will lower demand and increase supply. World trade volumes of both classes of wheat are expected to expand, but trade... |

| Superparamagnetic iron-oxide bound antimyoglobin (SPIOM) characteristics were analyzed at different pH. After injecting SPIOM in heart, ex vivo magnetic resonance microimaging (MRM) technique was used to visualize microvasculature of rat heart including cardiac arteries, veins, cordate tendons attached with valves. The measurement accuracy of ventricles, aorta, vasculature and dimensions of cordate tendons were close to coregistered histology measurements. |

| Excised mice kidney, heart and skin MRI visible features were quantitated using ex vivo 21 Tesla MRI microimager. The fast MRI acquisition protocols of FLASH, gradient echo flow compensated (GEFC) techniques were used to visualize microvasculature of mice kidney, mice heart including cardiac arteries, veins, cordate tendons and mice skin epidermis with hair follicle features. |

| The origins of signaling by vertebrate steroids are not fully understood. An important advance was the report that an estrogen-binding steroid receptor [SR] is present in amphioxus, a basal chordate with a similar body plan as vertebrates. To investigate the evolution of estrogen binding to steroid receptors, we constructed a 3D model of amphioxus SR complexed with estradiol. This 3D model indicates that although the SR is activated by estradiol, some interactions between estradiol and human ER[alpha] are not conserved in the SR, which can explain the low affinity of estradiol for the SR. These differences between the SR and ER[alpha] in the steroid-binding domain are sufficient to suggest that another steroid is the physiological regulator of the SR.... |

| Lamprey, a basal vertebrate, contains orthologs of the estrogen receptor (ER), progesterone receptor and corticoid receptor. A perplexing property of lamprey is that 15[alpha]-hydroxy-steroids are active steroids. For example, 15[alpha]-hydroxy-estradiol [15[alpha]-OH-E2] is the estrogen, instead of estradiol (E2). To investigate how 15[alpha]-OH-E2 binds lamprey ER, we constructed a 3D model of the lamprey ER with E2 and 15[alpha]-OH-E2. Our 3D model shows that S[delta] on Met-409 can form a hydrogen bond with the 15[alpha]-hydroxyl on 15[alpha]-OH-E2. In human ER[alpha], the corresponding residue Ile-424 has a van der Waals contact with 15[alpha]-OH-E2. BLAST analysis of GenBank indicates that among vertebrate ERs, only lamprey ER contains a... |
