Eyeblink Classical Conditioning and Post Traumatic Stress Disorder – A Model Systems Approach

open access: yesFrontiers in Psychiatry, 2015
Not everyone exposed to trauma suffers flashbacks, bad dreams, numbing, fear, anxiety, sleeplessness, hyper-vigilance, hyperarousal, or an inability to cope, but those who do may suffer from post traumatic stress disorder (PTSD).

In silico and in vitro exploration of a tyrosinase for biocatalytic production of catechols

open access: yesFEBS Open Bio, EarlyView.
Tyrosinase from Ralstonia pseudosolanacearum is a promising biocatalyst for producing valuable catechols from monophenol substrates. This tyrosinase is uniquely suited to this due to its high monophenolase : diphenolase ratio. We combined in silico docking and in vivo kinetic characterisation of this tyrosinase with 11 industrially relevant monophenols,

Facilitating evolutionary rescue from a wildlife health threat with cross-sectoral strategies: a case study on white-nose syndrome

open access: yesEcology and Society
Evolutionary rescue, the ability of a species to evolve under new selective pressures and rebound from threats, occurs within a social-ecological system.

Activation of dopamine receptors in the nucleus accumbens promotes sucrose-reinforced cued approach behavior

open access: yesFrontiers in Behavioral Neuroscience, 2016
Dopamine receptor activation in the nucleus accumbens (NAc) promotes vigorous environmentally-cued food-seeking in hungry rats. Rats fed ad libitum, however, respond to fewer food-predictive cues, particularly when the value of food reward is low.

Using fluorescence fluctuation spectroscopy to quantify molecular dynamics within cells

open access: yesFEBS Open Bio, EarlyView.
Microscopy techniques like fluorescence correlation spectroscopy (FCS) and number and brightness analysis (N&B) allow to quantify concentrations, diffusion rates, and oligomerization of fluorescently labeled molecules in the living cell. In this protocol the principles of how to set up these types of experiments are described including calibration ...

An investigation of the relationship between rate of responding during and acquisition and resistance to experimental extinction. [PDF]

open access: yes, 1975
Includes bibliographical references.The aim of the present series of experiments was to show that a direct relationship exists between two measures of response strength- rate of responding and resistance to extinction.

The conservation impact of botanical drones: Documenting and collecting rare plants from vertical cliffs and other hard‐to‐reach areas

open access: yesEcological Solutions and Evidence
A high percentage of island floras are at risk of extinction and have been reduced to relic populations, often in remote hard‐to‐reach areas. Uncrewed aircraft systems (UAS aka drones) are now being utilized to assist in the survey and collection of rare

Numerical model for estimating contribution of different components of crystalline cloud to extinction of optical radiation. Part 1. Scheme of qualitative estimation

open access: yesИзвестия Томского политехнического университета: Промышленная кибернетика
An analytical expression for extinction coefficient of optical radiation is proposed, taking into account various microphysical parameters of dispersed medium. The formula is product of the extinction factor and modified geometric value.

Characterization of the key membrane protein cytochrome Cyc2 from Ghiorsea bivora

open access: yesFEBS Open Bio, EarlyView.
This study reports the first detailed biochemical analysis of Cyc2TAG1_1, a cytochrome protein involved in microbial iron oxidation. We produced and purified this enzyme in E. coli, then measured its iron‐oxidizing efficiency, and characterized its electrical and structural properties.

Tiny habitats of tiny species: the importance of micro-refugia for threatened island-endemic arthropods

open access: yesOryx
Island-endemic arthropods are understudied species and likely to be highly threatened with extinction. Analysis of IUCN Red List assessments can be used to highlight important microhabitats requiring conservation for the effective management of island ...
