Livingstone, Alon Rimmer, S. Geoffrey Schladow, Eugene Silow, Lewis M. Sitoki, Rashid Tamatamah, Yvonne Vadeboncoeur, Peter B. Mcintyre

Biological Sciences Faculty Publications

Climate change is affecting lake stratification with consequences for water quality and the benefits that lakes provide to society. Here we use long-term temperature data (1970–2010) from 26 lakes around the world to show that climate change has altered lake stratification globally and that the magnitudes of lake stratification changes are primarily controlled by lake morphometry (mean depth, surface area, and volume) and mean lake temperature. Deep lakes and lakes with high average temperatures have experienced the largest changes in lake stratification even though their surface temperatures tend to be warming more slowly. These results confirm that the nonlinear relationship …

The Effects Of Moderate Prenatal Alcohol Exposure On Resting State Functional Connectivity And Its Relationship To Behavior, Carlos Rodriguez

Psychology ETDs

It is well established that heavy ethanol exposure during prenatal brain development leads to drastic morphological, cognitive and behavioral consequences. In contrast to heavy exposure, the effects of moderate prenatal alcohol exposure (PAE) are less severe yet continue well into adulthood. Animal models of PAE have been of immense importance to researchers for their ability to control for extraneous variables such as socio economic status, age, nutrition, stress, and co-exposure to other substances. Studies of moderate PAE have investigated several discrete brain regions, neurotransmitter systems, and animal behaviors. However, the effects of moderate PAE on resting state functional network connectivity …

Inotropes Are Not Linked To Increased Mortality In Heart Failure, Maya Guglin

The VAD Journal

How to use inotropes is one of the most controversial topics in the management of heart failure. While most clinicians use these drugs, and recognize the state of inotrope dependency, current guidelines recommend them onlu as a bridge or palliation. Thus, inotropes are considered either neutral or detrimental in terms of outcomes. Meanwhile, properly designed randomized clinical trials testing the outcomes on inotropes, have never been performed and it is unlikely that they will ever be attempted. These trials would require randomizing patients with advanced heart failure, low output syndrome, and impaired end-organ perfusion into groups that received or not …
