Varroa In The Aloha State, Tammy Horn

Tammy Horn

The Hawaiian word for fate is hopena, and since the early 1900s, it’s been a matter of hopena that Varroa mites would eventually come to the Islands. The inevitability increased in 2001 when APHIS/USDA forced Hawai’i to allow transshipments of queens and package bees from New Zealand to Canada to pass through its ports. Since Varroa arrived on Oahu in 2006 and on the Big Island in 2008, many agencies have been working together to create appropriate infrastructure to address the latest arrival. According to Hawai’i Department of Agriculture (HDOA) branch chief Neil Reimer, 'Before Varroa showed up in Hawai’i, …

The Graphic Novel As A Choice Of Weapons, Tammy Horn

Tammy Horn

In the late 1930s, the photographer Gordon Parks arrived in Washington, DC, to work with Roy Stryker, director of the Farm Security Administration. Parks' first assignment was to tour the nation's capital, a city still governed by Jim Crow laws. Stryker locked Parks' camera in a closed and then bade the young black man adieu, with the expectation Parks would not return for a week.

Polymorphic Ros Scavenging Revealed By Cccp In A Lizard, Mats Olsson, Mark Wilson, Caroline Isaksson, Tobias Uller

Mark R Wilson

Ingestion of antioxidants has been argued to scavenge circulating reactive molecules (e.g., free radicals), play a part in mate choice (by mediating access to this important resource), and perhaps increase life span. However, recent work has come to question these relationships. We have shown elsewhere in the polychromatic lizard, Ctenophorus pictus, that diet supplementation of carotenoids as antioxidants does not depress circulating natural reactive oxygen species (ROS) levels and leads to no corresponding improvement of color traits. However, a much stronger test would be to experimentally manipulate the ROS levels themselves and assess carotenoid-induced ROS depression. Here, we achieve this …

The Chaperone Action Of Clusterin And Its Putative Role In Quality Control Of Extracellular Protein Folding, Amy Wyatt, Justin Yerbury, Stephen Poon, Rebecca Dabbs, Mark Wilson

Mark R Wilson

The function(s) of clusterin may depend upon its topological location. A variety of intracellular "isoforms" of clusterin have been reported but further work is required to better define their identity. The secreted form of clusterin has a potent ability to inhibit both amorphous and amyloid protein aggregation. In the case of amorphous protein aggregation, clusterin forms stable, soluble high-molecular-weight complexes with misfolded client proteins. Clusterin expression is increased during many types of physiological and pathological stresses and is thought to function as an extracellular chaperone (EC). The pathology of a variety of serious human diseases is thought to arise as …
