Transcranial direct current stimulation (tDCS) has been used aiming to boost exercise performance and inconsistent findings have been reported. One possible explanation is related to the limitations of the so-called “conventional” tDCS, which uses large rectangular electrodes, resulting in a diffuse electric field. A new tDCS technique called high-definition tDCS (HD-tDCS) has been recently developed. HD-tDCS uses small ring electrodes and produces improved focality and greater magnitude of its aftereffects. This study tested whether HD-tDCS would improve exercise performance to a greater extent than conventional tDCS. Twelve endurance athletes (29.4 ± 7.3 years; 60.15 ± 5.09 ml kg− 1 min− …

Patient-Derived Ipsc-Cerebral Organoid Modeling Of The 17q11.2 Microdeletion Syndrome Establishes Crlf3 As A Critical Regulator Of Neurogenesis, Michelle L Wegscheid, Corina Anastasaki, Kelly A Hartigan, Olivia M Cobb, Jason B Papke, Jennifer N Traber, Stephanie M Morris, David H Gutmann

Open Access Publications

Neurodevelopmental disorders are often caused by chromosomal microdeletions comprising numerous contiguous genes. A subset of neurofibromatosis type 1 (NF1) patients with severe developmental delays and intellectual disability harbors such a microdeletion event on chromosome 17q11.2, involving the NF1 gene and flanking regions (NF1 total gene deletion [NF1-TGD]). Using patient-derived human induced pluripotent stem cell (hiPSC)-forebrain cerebral organoids (hCOs), we identify both neural stem cell (NSC) proliferation and neuronal maturation abnormalities in NF1-TGD hCOs. While increased NSC proliferation results from decreased NF1/RAS regulation, the neuronal differentiation, survival, and maturation defects are caused by reduced cytokine receptor-like factor 3 (CRLF3) expression and …

The Motion Of Trees In The Wind: A Data Synthesis, Toby D. Jackson, Sarab Sethi, Ebba Dellwik, Nikolas Angelou, Amanda Bunce, Tim Van Emmerik, Mark Rudnicki, Et. Al.

Michigan Tech Publications, Part 1

Interactions between wind and trees control energy exchanges between the atmosphere and forest canopies. This energy exchange can lead to the widespread damage of trees, and wind is a key disturbance agent in many of the world's forests. However, most research on this topic has focused on conifer plantations, where risk management is economically important, rather than broadleaf forests, which dominate the forest carbon cycle. This study brings together tree motion time-series data to systematically evaluate the factors influencing tree responses to wind loading, including data from both broadleaf and coniferous trees in forests and open environments. We found that …

Are Websites Of Victim Service Organizations Representative Of Women Of Color? A Content Analysis, Loretta Addo-Danso

Theses and Dissertations

Intimate partner violence continues to be on the raise among women of color in the country. Many scholars have attributed this to the multiple factors such as race, class and sexual orientation that intersect to influence women of color’s experiences with intimate partner violence. Yet, there seems to be a gap in the services that are rendered to women of color who are survivors. To better understand how representative victim services are of women of color, a content analysis of victim service organizations’ websites nationwide was conducted to ascertain the extent to which the organizations are inclusive of survivors/victims of …
