Iowa Farm Land Values Reach All Time High

Farm enlargement, scarcity of farms for sale, contract buying and non-farm use were major factors in the 1964 Iowa land price rise, according to real estate brokers contracted in ISU\u27s annual land value survey

COVID-19 Vaccines as Global Public Goods

Vulnerable: The Law, Policy and Ethics of COVID-19 confronts the vulnerabilities that have been revealed by the pandemic and its consequences. It examines vulnerabilities for people who have been harmed or will be harmed by the virus directly and those harmed by measures taken to slow its relentless march; vulnerabilities exposed in our institutions, governance, and legal structures; and vulnerabilities in other countries and at the global level where persistent injustices affect us all. COVID-19 has forced us to not only reflect on how we govern and how we set policy priorities, but also to ensure that pandemic preparedness, precautions, and recovery include all individuals, not just some

One hundred years after the discovery of insulin and glucagon:the history of tumors and hyperplasias that hypersecrete these hormones

One century ago, in 1922, Frederick G Banting, Charles H Best, James B Collip and John J R Macleod first published their experiments resulting in the isolation of a hypoglycemic factor, named insulin, from a solution extract from a dog’s pancreas. One year later, in 1923, a hyperglycemic factor named glucagon was isolated by Charles P Kimball and John R Murlin. In the following years, it could be demonstrated that pancreatic islet alpha- and beta-cell neoplasms and hyperplasias could inappropriately secrete excessive amounts of these two hormones. This review is a sequel to the discovery of insulin and glucagon and introduces the history of this fascinating group of neuroendocrine neoplasms and hyperplasias of the pancreas.</p

Leukocyte Response in the Dog and Cat

The total and differential leukocyte counts are the tests used in monitoring the leukocyte numbers and proportions in large vessel peripheral blood. Knowledge of leukocyte origin, function, and transitory presence in the peripheral blood is imperative when evaluating change in white blood cell and differential counts

High-Resolution spectroscopy of the low-mass X-ray binary EXO 0748-67

We present initial results from observations of the low-mass X-ray binary EXO 0748-67 with the Reflection Grating Spectrometer on board the XMM-Newton Observatory. The spectra exhibit discrete structure due to absorption and emission from ionized neon, oxygen, and nitrogen. We use the quantitative constraints imposed by the spectral features to develop an empirical model of the circumsource material. This consists of a thickened accretion disk with emission and absorption in the plasma orbiting high above the binary plane. This model presents challenges to current theories of accretion in X-ray binary systems.Comment: 5 pages, 4 figures, accepted by A&A letters, XMM special issu
