Challenges of NTM Drug Development
(Frontiers, 2018-07-18)
Discovery and development of antibiotics active against the environmental opportunistic non-tuberculous mycobacteria (NTM) have been retarded by innate antibiotic-resistance of NTM cells and methodological challenges in ...
The Skin Microbiome of the Neotropical Frog Craugastor fitzingeri: Inferring Potential Bacterial-Host-Pathogen Interactions From Metagenomic Data
(Frontiers, 2018-03-20)
Skin symbiotic bacteria on amphibians can play a role in protecting their host against pathogens. Chytridiomycosis, the disease caused by Batrachochytrium dendrobatidis, Bd, has caused dramatic population declines and ...
Culture Media and Individual Hosts Affect the Recovery of Culturable Bacterial Diversity from Amphibian Skin
(Frontiers, 2017-08-24)
One current challenge in microbial ecology is elucidating the functional roles of the large diversity of free-living and host-associated bacteria identified by culture-independent molecular methods. Importantly, the ...
Chromosome Bridges Maintain Kinetochore-Microtubule Attachment throughout Mitosis and Rarely Break during Anaphase
(PLOS, 2016-01-19)
Accurate chromosome segregation during cell division is essential to maintain genome stability, and chromosome segregation errors are causally linked to genetic disorders and cancer. An anaphase chromosome bridge is a ...
Analysis of the Optimal Duration of Behavioral Observations Based on an Automated Continuous Monitoring System in Tree Swallows (Tachycineta bicolor): Is One Hour Good Enough?
(PLOS, 2015-11-11)
Studies of animal behavior often rely on human observation, which introduces a number of limitations on sampling. Recent developments in automated logging of behaviors make it possible to circumvent some of these problems. ...
Winter Latitudinal Population Age-Structure of a Migratory Seagull (Larus fuscus) Differs between Its Two Major Migratory Flyways
(Hindawi, 2013-12-08)
The migration is energy-demanding and is expected to greatly affect the distribution of individuals over the species range and condition the choice of migratory routes. We investigated the wintering distributions and ...
Incremental evaluation of coupled cluster dipole polarizabilities
(The Royal Society of Chemistry, 2014-12-16)
In this work we present the first implementation of the incremental scheme for coupled cluster linear-response frequency-dependent dipole polarizabilities. The implementation is fully automated and makes use of the ...
Fabrication of Nanostructured Kaolinite Doped Composite Films from Silicone Rubber with Enhanced Properties
(MDPI, 2019-05-12)
Naturally occurring nanomaterials are finding growing interests in tailoring properties of engineering polymers for advanced applications. The objective of this study was to develop environment-friendly nanocomposite films ...
Body Condition Indices Predict Reproductive Success but Not Survival in a Sedentary, Tropical Bird
(PLOS, 2015-08-25)
Body condition may predict individual fitness because those in better condition have more resources to allocate towards improving their fitness. However, the hypothesis that condition indices are meaningful proxies for ...
Biotic interactions are an unexpected yet critical control on the complexity of an abiotically driven polar ecosystem
(Springer Nature, 2019-02-15)
Abiotic and biotic factors control ecosystem biodiversity, but their relative contributions remain unclear. The ultraoligotrophic ecosystem of the Antarctic Dry Valleys, a simple yet highly heterogeneous ecosystem, is a ...
