Targeted and modular architectural polymers employing bioorthogonal chemistry for quantitative therapeutic delivery.

Chem Sci 2020 Mar 6;11(12):3268-3280. Epub 2020 Mar 6.

Centre for Advanced Imaging, The University of Queensland Brisbane QLD 4072 Australia

There remain several key challenges to existing therapeutic systems for cancer therapy, such as quantitatively determining the true, tissue-specific drug release profile , as well as reducing side-effects for an increased standard of care. Hence, it is crucial to engineer new materials that allow for a better understanding of the pharmacokinetic/pharmacodynamic behaviours of therapeutics. We have expanded on recent "click-to-release" bioorthogonal pro-drug activation of antibody-drug conjugates (ADCs) to develop a modular and controlled theranostic system for quantitatively assessing site-specific drug activation and deposition from a nanocarrier molecule, by employing defined chemistries.

Salmonella Genomics in Public Health and Food Safety.

EcoSal Plus 2021 Jun 14:eESP00082020. Epub 2021 Jun 14.

Center for Food Safety and Applied Nutrition, U.S. Food and Drug Administration, College Park, Maryland, USA.

The species Salmonella enterica comprises over 2,600 serovars, many of which are known to be intracellular pathogens of mammals, birds, and reptiles. It is now apparent that Salmonella is a highly adapted environmental microbe and can readily persist in a number of environmental niches, including water, soil, and various plant (including produce) species. Much of what is known about the evolution and diversity of nontyphoidal Salmonella serovars (NTS) in the environment is the result of the rise of the genomics era in enteric microbiology. Read More

Entropy Scaling of Viscosity - II: Predictive Scheme for Normal Alkanes.

Ian H Bell

J Chem Eng Data 2020 Oct;65(11)

Applied Chemicals and Materials Division, National Institute of Standards and Technology, Boulder, CO 80305.

In this work, a residual entropy value 6/10 of the way between the critical point and a value of -2/3 of Boltzmann's constant is shown to collapse the scaled viscosity for the family of normal alkanes. Based on this approach, a nearly universal correlation is proposed that can reproduce 95% of the experimental data for normal alkanes within ±18% (without removal of clearly erroneous data). This universal correlation has no new fluid-specific empirical parameters and is based on experimentally accessible values. Read More

A model of the burglar alarm hypothesis of prey alarm calls.

Theor Popul Biol 2021 Jun 8. Epub 2021 Jun 8.

Department of Mathematics and Statistics, University of Maryland Baltimore County, Baltimore, MD, United States of America. Electronic address:

When approached by a predator many prey species will emit an "alarm call" as a form of anti-predator behavior. One hypothesis for the function of alarm calls is the "burglar alarm" hypothesis whereby upon attack, a prey renders itself dangerous to a predator by generating an alarm call that attracts a predator at higher trophic levels in the food chain; that is, attracts a predator to the prey's own predator. This paper concerns a model incorporating a mechanism to test the burglar alarm hypothesis. Read More

Many-Body Nonlocality as a Resource for Quantum-Enhanced Metrology.

Phys Rev Lett 2021 May;126(21):210506

Faculty of Physics, University of Warsaw, Ulica Pasteura 5, PL-02-093 Warszawa, Poland.

We demonstrate that the many-body nonlocality witnessed by a broad family of Bell inequalities is a resource for ultraprecise metrology. We formulate a general scheme which allows one to track how the sensitivity grows with the nonlocality extending over an increasing number of particles. We illustrate our findings with some prominent examples-a collection of spins forming an Ising chain and a gas of ultracold atoms in any two-mode configuration. Read More

A Robust Incubator to Improve Access to Microbiological Culture in Low Resource Environments.

J Med Device 2019 Mar 22;13(1):0110071-110077. Epub 2019 Jan 22.

Intellectual Ventures Global Good Fund, Bellevue, WA 98007.

To help address the limitations of operating conventional microbiological culture incubators in low resource environments, a new incubator design was developed and tested to meet the requirements of operation in laboratories without reliable power (power outages up to 12 contiguous hours) or climate control (ambient indoor temperatures from 5 °C to 45 °C). The device is designed to enable adherence to incubation temperatures recommended for growth detection, identification, and drug susceptibility testing (DST) of human pathogenic bacteria. During power outages, stable temperatures are maintained in the device's internal sample compartment by employing phase change material (PCM) as a bi-directional thermal battery to maintain incubation temperature.

Ann Appl Stat 2021 Mar 18;15(1):323-342. Epub 2021 Mar 18.

School of Forestry and Environmental Studies, Department of Environmental Health Sciences, Yale University.

We introduce spatial (DLfuse) and spatiotemporal (DLfuseST) distributed lag data fusion methods for predicting point-level ambient air pollution concentrations, using, as input, gridded average pollution estimates from a deterministic numerical air quality model. The methods incorporate predictive information from grid cells surrounding the prediction location of interest and are shown to collapse to existing downscaling approaches when this information adds no benefit. The spatial lagged parameters are allowed to vary spatially/spatiotemporally to accommodate the setting where surrounding geographic information is useful in one area/time but not in another.
