The Role of Scientists and Clinicians in Raising Public Support for Animal Research in Reproductive Biology and Medicine.
- 2012
-
In: Biology of reproduction. - : Oxford University Press (OUP). - 1529-7268 .- 0006-3363.

Journal article (peer-reviewed)abstract
- It is important that researchers active in reproductive animal research, as a group, clearly and compassionately convey specific information to students, patients, and the general public on the merit and need for biomedical research using various formats and seek active support from patient organizations, universities, politicians, celebrities, the media, and international professional organizations related to human and animal health.

Chromium oxidation by manganese (hydr)oxides in a California aquifer
- 2010
-
In: Applied Geochemistry. - : Elsevier BV. - 0883-2927 .- 1872-9134. ; 25:3, s. 377-381
-
Journal article (peer-reviewed)abstract
- There are increasing concerns with elevated levels of Cr(VI) in the environment because It IS a Strong oxidant. corrosive, and carcinogenic The concerns extend to the presence of Cr(VI) in many aquifers in California and elsewhere. where relatively high levels have been attributed to both industrial pollution and natural processes The authors have, therefore, determined if natural redox processes contribute to the presence of high Cr(VI) concentrations (6-36 mu g L-1) in all aquifer in central California relative to non-detectable concentrations (<0.1 mu g L-1) in all adjacent aquifer Specifically, the distribution and the redox speciation of dissolved (<0.45 mu m) Cr have been compared with those of particulate Mn and Fe oxy-hydioxides in sediments, using X-ray absorption spectroscopy at the Mn and Fe L-edges The analyses show a correlation between the presence of dissolved Cr(VI) and Mn (hydr)oxide minerals, which are the only common, naturally occurring minerals known to oxidize Cr(Ill) in laboratory experiments This covariance substantiates the results of those experiments and previous field studies that indicate natural oxidation mechanisms might account for the relatively high levels of Cr(VI) in the study site. as well as for elevated concentrations in other aquifers with similar biogeochemical conditions.

ASPIRE The Amundsen Sea Polynya International Research Expedition
- 2012
-
In: Oceanography. - : The Oceanography Society. - 1042-8275. ; 25:3, s. 40-53
-
Journal article (peer-reviewed)abstract
- In search of an explanation for some of the greenest waters ever seen in coastal Antarctica and their possible link to some of the fastest melting glaciers and declining summer sea ice, the Amundsen Sea Polynya International Research Expedition (ASPIRE) challenged the capabilities of the US Antarctic Program and RVIB Nathaniel B. Palmer during Austral summer 2010-2011. We were well rewarded by both an extraordinary research platform and a truly remarkable oceanic setting. Here we provide further insights into the key questions that motivated our sampling approach during ASPIRE and present some preliminary findings, while highlighting the value of the Palmer for accomplishing complex, multifaceted oceanographic research in such a challenging environment.
