Thompson, Katz and Sheehan: Chemical comparison of Prunus africana bark and pygeum products marketed for prostate health.

New publication from Rob Thompson, Professor of Chemistry, with senior Daniel Katz and Brendan Sheehan (OC'18, biochemistry).

Chemical comparison of Prunus africana bark and pygeum products marketed for prostate health.
Journal of Pharmaceutical and Biomedical Analysis Vol. 163, 30 January 2019, pp. 162-169

Access this title at the OhioLINK Electronic Journal Center or at the publisher's site, Elsevier's ScienceDirect.

From the introduction and conclusions:

"Pygeum is the powdered bark of Prunus africana (also called Pygeum africanum), an evergreen tree that grows across the mountainous regions of Africa. Both the powder and a lipophilic extract are sold commercially under the same name... Ingestion of pygeum has been found to inactivate the androgen receptor and inhibit prostate cancer cell growth."

[Conclusions after chemical analysis of samples of both bark and pygeum powder:]

Harvesting Prunus africana bark. 
Credit: SouthWorld, May 1, 2016

"The amounts per gram of the BPH-active compounds atranorin, atraric acid, total ferulic acid, and total beta-sitosterol and the fractions of free beta-sitosterol were quite different in bark from Prunus africana and in the contents of commercial pygeum capsules, contents purported to be derivatives of the same bark. This was unexpected and suggested that the BPH-active components in commercial pygeum may not be fully sourced from natural materials as labeled. Also unexpected was that no N-butylbenzene sulfonamide was found in any sample. The variation in the composition of four bark samples, two of which were botanical reference materials, demonstrated the need for a phytochemical standard for pygeum, with reference values for the BPH-active compounds studied here."

What Neil deGrasse Tyson Thinks Higher Ed Gets Wrong

In this interview with The Chronicle of Higher Education, Tyson discusses "how to explain science to the masses and [rips] into what he sees as higher education’s misguided incentive system, valuing research over teaching and public service and not creating space for people like him to flourish. 'It’s a sad fact,' he says, 'for the future of science in America.' "

Astrophysics for People in a Hurry is one of Tyson's most recent books.  The science library's copy is checked out, but there are plenty of other copies to borrow through OhioLINK.

Jordan Price and students publish in Journal of Bacteriology

New publication by Jordan Price, Assistant Professor of Biology, with students Kallie Jiang and Abby Galantowicz, and collaborators at Univ Calif Berkeley:

Price, Jordan V.; Jiang, Kallie; Galantowicz, Abby; Freifeld, A., & Vance, R. E. (2018). Legionella pneumophila is directly sensitive to 2-deoxyglucose-phosphate via its UhpC transporter but is indifferent to shifts in host cell glycolytic metabolism. Journal of Bacteriology, 200(16), 176. doi:10.1128/JB.00176-18 ER

Importance of this research:  "We explored the relationship between macrophage glycolysis and replication of an intracellular bacterial pathogen, Legionella pneumophila. Previous studies demonstrated that a glycolysis inhibitor, 2-deoxyglucose (2DG), blocks replication of L. pneumophila during infection of macrophages, leading to speculation that L. pneumophila may exploit macrophage glycolysis. We isolated L. pneumophila mutants resistant to the inhibitory effect of 2DG in macrophages, identifying a L. pneumophila hexose-phosphate transporter, UhpC, that is required for bacterial sensitivity to 2DG during infection. Our results reveal how a bacterial transporter mediates the direct antimicrobial effect of a toxic metabolite. Moreover, our results indicate that neither induction nor impairment of host glycolysis inhibits intracellular replication of L. pneumophila, which is consistent with a view of L. pneumophila as a metabolic generalist."

Recent research by Associate Professor of Biology Angie Roles and collaborators "assessed phenotypes associated with survival and reproductive success in over 30,000 plants representing 100 mutation accumulation lines of Arabidopsis thaliana across four temporal environments at a single field site." The authors conclude, "The combination of large environmental variance with a mean effect of mutation near zero suggests that mutations could contribute substantially to standing genetic variation."

Partial abstract:
"We search for an isotropic stochastic gravitational-wave background (GWB) in the newly released 11. year data set from the North American Nanohertz Observatory for Gravitational Waves (NANOGrav). While we find no evidence for a GWB, we place constraints on a population of inspiraling supermassive black hole (SMBH) binaries, a network of decaying cosmic strings, and a primordial GWB. For the first time, we find that the GWB constraints are sensitive to the solar system ephemeris (SSE) model used and that SSE errors can mimic a GWB signal."   Learn more about NANOGrav

Plethodon glutinosus, from Caudata.org

Salamander climbing behavior varies among species and is correlated with community composition.
Tori D Mezebish, August Blackman, Alexander J Novarro.
Behavioral Ecology, Volume 29, Issue 3, 9 May 2018, Pages 686–692,
https://doi.org/10.1093/beheco/ary022 (open access)

Partial abstract: Species coexistence is often facilitated by behavioral strategies that minimize competition for limited resources. Terrestrial, kingless salamanders (genus Plethodon) coexist in predictable assemblages of body size guilds, but little is known about the behavioral mechanisms that promote such coexistence. Here, we considered the hypothesis that Plethodon salamanders use climbing behavior to reduce competitive interactions, thereby promoting coexistence through spatial partitioning.  (As indexed in Web of Science)

GENOME BIOLOGY AND EVOLUTION  Volume: 10  Issue: 3  Pages: 999-1011
DOI: 10.1093/gbe/evy061  Published: MAR 2018
 
Partial abstract: Genes that are inherently subject to strong selective constraints tend to be overretained in duplicate after polyploidy. They also continue to experience similar, but somewhat relaxed, constraints after that polyploidy event. We sought to assess for how long the influence of polyploidy is felt on these genes' selective pressures. We analyzed two nested polyploidy events in Brassicaceae: the At-a genome duplication that is the most recent polyploidy in the model plant Arabidopsis thaliana and a more recent hexaploidy shared by the genus Brassica and its relatives... Our results paint a picture of the long-lived effects of polyploidy on plant genomes, suggesting that even yesterday's polyploids still have distinct evolutionary trajectories.

Communicating science: two new books just received

Catalog record in OBIS

Hope Jahren, author of Lab Girl, is the guest editor of The Best American Science and Nature Writing, 2017.   Jahren is the recipient of three Fulbright Awards and is one of four scientists, and the only woman, to have been awarded both of the Young Investigator Medals given within the Earth Sciences.  Included among the essays is "Out Here, No One Can Hear You Scream," by Kathryn Joyce (Huffington Post).  It is an all too timely account of sexual harassment and hostility targeting women who work for various national and state agencies that protect America's natural heritage.

An essay by Elizabeth Kolbert, author of The Sixth Extinction and Field Notes from a Catastrophe, also appears in this volume.  "A Song of Ice" (from The New Yorker) recounts her visits to Greenland, where the effects of global warming are extraordinary and devastating.

 Catalog record in OBIS

All of the essays, as always in this series, are important reading.  Borrow the book over Winter Term - an essay a night will get you through the month of January with a lot to ponder.

Learn more about the science of science communication with this new handbook from Oxford University Press.  A key question considered in the handbook is: "What can we know empirically about the impact of the full range of scientists' linguistic choices and potential alternatives on public debate?"  Given the importance of scientific literacy (or at least realistic perceptions of scientists' work) for a healthy, just society, David Kirby's chapter on "The Changing Popular Images of Science" is very instructive.
