For the last 500 years, the Americas have been a melting pot both for genetically diverse humans and for the pathogenic and commensal organisms associated with them. One such organism is the stomach-dwelling bacterium Helicobacter pylori, which is highly prevalent in Latin America where it is a major current public health challenge because of its strong association with gastric cancer. By analyzing the genome sequence of H. pylori isolated in North, Central and South America,...

Correlates of War, 1816-1997

J. David Singer & Melvin Small
This data collection is part of the Correlates of War (COW) Project at the University of Michigan under the guidance of J. David Singer and Melvin Small. The data contain statistics of extra-, inter-, and intra-state wars fought from 1816-1997. Variables for extra-state wars include name of war, name of participants, date ranges, victor designation, outside intervention, theater designation, and total battle deaths. Inter-state wars include date ranges, on which side the state intervened, if...

Data from: Interactive effects of productivity and predation on zooplankton diversity

Mitra Asgari & Christopher F. Steiner
Recent studies suggest the necessity of understanding the interactive effects of predation and productivity on species coexistence and prey diversity. Models predict that coexistence of prey species with different competitive abilities can be achieved if inferior resource competitors are less susceptible to predation and if productivity and/or predation pressure are at intermediate levels. Hence, predator effects on prey diversity are predicted to be highly context dependent: enhancing diversity from low to intermediate levels of productivity...

Data from: Trophoblast survival signaling during human placentation requires HSP70 activation of MMP2-mediated HBEGF shedding

Chandni V. Jain, Philip Jessmon, Charbel T. Barrak, Alan D. Bolnick, Brian A. Kilburn, Michael Hertz & D. Randall Armant
Survival of trophoblast cells in the low oxygen environment of human placentation requires metalloproteinase-mediated shedding of HBEGF and downstream signaling. A matrix metalloproteinase (MMP) antibody array and quantitative RT-PCR revealed upregulation of MMP2 post-transcriptionally in human first trimester HTR-8/SVneo trophoblast cells and placental villous explants exposed to 2% O2. Specific MMP inhibitors established the requirement for MMP2 in HBEGF shedding and upregulation. Because α-amanitin inhibited the upregulation of HBEGF, differentially expressed genes were identified by...

Wages of War, 1816-1965

J. David Singer & Melvin Small
The Wages of War is part of the Correlates of War (COW) Project at the University of Michigan under the guidance of J. David Singer and Melvin Small. The data are meant to be a statistical handbook of war from 1816-1965. It includes mainly bivariate data on every war fought in the time period. War data described cover all international wars that began and ended between 1816 and 1965, and those that satisfied the theoretical...

Wages of War, 1816-1980: Augmented with Disputes and Civil War Data

J. David Singer & Melvin Small
These data were collected to study the trends and changes in the frequency, magnitude, severity, and intensity of international wars, civil wars, and international disputes. The data collection consists of two separate datasets. For each dataset, the unit of analysis is the participant in a particular conflict. While the two datasets are related, they are mutually exclusive in that each describes a particular type of war (interstate or civil) or a dispute. Part 1, Experience...
