1 Beseris, EthanBiological impact protection in human facial hairOur study investigated selective mechanisms that influenced the evolution of facial hair in human males (Homo sapiens). Beards are often perceived as an indicator of masculinity and social dominance in men, suggesting that they may play a role in male contest competition. Some authors propose that t...2018
2 Davis, Kacey A.Expression and Purification of Augertoxins: Searching for Novel Protein Folds in Venomous Marine SnailsThis study describes a method for bacterial expression and purification of previously uncharacterized proteins. The proteins chosen for this study come from auger snail toxins, which have evolved to help the snail hunt and kill their prey. Evolutionary pressure between predator and prey selects for ...2018
3 Lee, HaniPost-traumatic headache: an opportunity to develop new preclinical models for better understanding of pathology and treatmentPost-traumatic headache (PTH) is identified as one of the most frequent symptoms following traumatic brain injury (TBI) (Faux & Sheedy, 2008). Despite the high prevalence, there are currently no treatments which specifically target PTH. Instead of etiology-specific treatments, individuals suffering ...2022
4 Bell, Anthony W.The expansion of pinyon-juniper woodland and the appearance of peromyscus truel in the Toiyabe range of central NevadaIn the early twentieth century field biologists from the University of California Museum of Vertebrate Zoology conducted vertebrate faunal surveys throughout the Great Basin region. Over the past several years we have been conducting resurveys of many of the localities visited by MVZ scientists. Our...Piñon mouse -- Nevada -- Toiyabe Range; Piñon mouse -- Habitat -- Nevada -- Toiyabe Range; Piñon mouse -- Climatic factors -- Nevada -- Toiyabe Range2012-05
5 Richards, JacksonChasing channels: Progress in calcium channel localization in the C. Elegans synapseCalcium channels play a crucial role in neurotransmission by facilitating the flow of calcium ions necessary for synaptic vesicle fusion and neurotransmitter release. Different types of calcium channels participate in this process in the neurons of the nematode C. elegans. L- and N-type channels res...Calcium channels; Synaptic vesicles; Caenorhabditis elegans2013-05
6 Skedros, Gregory AthanasiosStructural and material changes in the sheep radius from newborn to adult: Functional adaptation versus developmental constraintBones that exhibit marked changes in structural and material characteristics during ontogeny are potentially useful for studying the mechanisms that produce functional adaptations. The diaphyseal region of the sheep radius was examined because it is relatively simply loaded in cranial-caudal bending...Functional adaptations - Sheep; Developmental constraint - Sheep; Ontogeny2015-08
7 Hunter, SamuelSignaling Role of the Hamp Domain in the Escherichia Coli Serine ChemoreceptorThe chemoreceptor Tsr enables Escherichia coli to track serine gradients in its environment. Binding of serine to the periplasmic domain propagates a signaling conformational change through other domains of the chemoreceptor molecule to modulate the activity of CheA, a kinase associated with t...Chemoreceptors - Research2016-07
8 Peterson, MikalSomatic chromosome pairing in interspecific drosophila hybrid and hybried rescue crossesHomologous chromosomes of somatic tissue pair together in Drosophila. One current model proposes that somatic pairing starts in an undirected manner; when sites on the chromosome, called "buttons", come into contact and pair. Then, after this initial pairing, the rest of the chromosome then synapses...2022
9 Peterson, JohnPotential Therapeutic Inhibition of Epigenetic Modulator LSDI in Glioblastoma MultiformeGlioblastoma (GBM) is the most common primary brain tumor in adults, and while advances in surgery, radiation, and standard chemotherapies have improved survival in this disease marginally over the years, the outcomes for most patients remain disappointing (Bhat, 2013). Recent studies have identifie...
10 Bader, CecilyThe Response of Arabidopsis Mutant BPS1-2 on Salt MediaHow would our world change if salt tolerance could be engineered in plants? The Arabidopsis mutant bps1-2 has been shown to respond differently on salt media than a nonmutated plant would. In normal conditions, the bps1-2 mutant will arrest development in the root and shoot shortly after germination...2017
