We propose two strategies to characterize organisms with respect to their metabolic capabilities. The first, investigative, strategy describes metabolic networks in terms of their capability to utilize different carbon sources, resulting in the concept of carbon utilization spectra. In the second, predictive, approach minimal nutrient combinations are predicted from the structure of the metabol...

The African Hyaenodontida, mainly known from the Late Eocene and Early Oligocene Fayum depression in Egypt, show a very poor diversity in oldest Paleogene localities. Here we report new hyaenodontidans found in the late Middle Eocene deposits of Dur At-Talah (Central Libya), known to have recorded the earliest radiation of African anthropoids. The new hyaenodontidan remains are represented by d...

Ectotherms have evolved preferences for particular body temperatures, but the nutritional and life-history consequences of such temperature preferences are not well understood. We measured thermal preferences in Locusta migratoria (migratory locusts) and used a multi-factorial experimental design to investigate relationships between growth/development and macronutrient utilization (conversion o...

BACKGROUND Large livestock farms might increase the infection risk for the nearby human population because of an increased risk for disease outbreaks and because antibiotic-resistant bacteria are more likely to be present. We hypothesized that populations residing in rural areas have more contact with cattle compared with populations in urban areas, and will use more antibiotics or more frequen...

optimal reduction in blood pressure with antihypertensive agents helps to prevent microvascular and macrovascular complications of diabetes. the objective of the study was to evaluate the current utilization pattern of antihypertensive medications among patients with diabetes and coexistent hypertension as per the jnc seventh report guidelines. a cross-sectional survey was conducted among patie...

the goal of this study was to evaluate the pattern and the suitability of the human albumin usage according to the available and reliable guidelines. a concurrent, cross-sectional study was performed in shariati hospital (associated with tehran university of medical sciences, tehran, iran). all inpatient adults that were prescribed albumin during the study period were evaluated to register the ...

BACKGROUND Attenuation of the P-wave amplitudes in patients with peripheral edema (PERED) has been recently reported, with P-waves regaining some of their amplitude in patients, who subsequently experienced amelioration of their PERED. Changes in the P-waves correlated with the corresponding alterations in the QRS complexes. Also since amplitudes and durations of QRS complexes changed in parall...

Laboratory populations of a green alga cultured in the dark with an organic substrate evolved into efficient heterotrophs with faster growth, higher fitness, and increased responsiveness to substrate concentration. Their phenotypes were almost entirely attributable to selection, rather than to history or ancestry. The fitness of evolved lines in the light was uniformly depressed, presumably thr...

In Dur, Hammond, and Morrill (2017), we provided evidence in favor of a novel classification methodology for identifying sincere and sophisticated students in school-choice matching mechanisms. Our approach allowed us to demonstrate support for previously untested claims in the theoretical matching literature regarding the distributional consequences of using a manipulable mechanism. In this ap...
