Adolescent Alcohol Exposure Results in Sex-specific Alterations in Conditioned Fear Learning and Memory in Adulthood

open access: yesFrontiers in Pharmacology, 2022
The present study used auditory fear conditioning to assess the impact of repeated binge-like episodes of alcohol exposure during adolescence on conditioned fear in adulthood.

When hot water freezes before cold [PDF]

open access: yes, 2006
I suggest that the origin of the Mpemba effect (the freezing of hot water before cold) is freezing-point depression by solutes, either gaseous or solid, whose solubility decreases with increasing temperature so that they are removed when water is heated.

Oocyte, embryo and blastocyst cryopreservation in ART: systematic review and meta-analysis comparing slow-freezing versus vitrification to produce evidence for the development of global guidance

open access: yesHuman Reproduction Update, 2016
BACKGROUND Successful cryopreservation of oocytes and embryos is essential not only to maximize the safety and efficacy of ovarian stimulation cycles in an IVF treatment, but also to enable fertility preservation.

Pre-freezing of multifractal exponents in Random Energy Models with logarithmically correlated potential [PDF]

open access: yes, 2009
Boltzmann-Gibbs measures generated by logarithmically correlated random potentials are multifractal. We investigate the abrupt change ("pre-freezing") of multifractality exponents extracted from the averaged moments of the measure - the so-called inverse

Relativistic freeze-in

open access: yesPhysics Letters B, 2019
We study production of scalar dark matter via the freeze--in mechanism in the relativistic regime, focussing on the simplest Higgs portal model. We derive the corresponding relativistic reaction rates based on the Bose--Einstein statistics taking into account the thermal mass effects as well as the change in the Higgs degrees of freedom at the ...

The arabidopsis RCC1 family protein TCF1 regulates freezing tolerance and cold acclimation through modulating lignin biosynthesis [PDF]

open access: yes, 2015
Cell water permeability and cell wall properties are critical to survival of plant cells during freezing, however the underlying molecular mechanisms remain elusive.

Collective Transformation of Water between Hyperactive Antifreeze Proteins: RiAFPs

open access: yesCrystals, 2019
We demonstrate, by molecular dynamics simulations, that water confined between a pair of insect hyperactive antifreeze proteins from the longhorn beetle Rhagium inquisitor is discontinuously expelled as the two proteins approach each other at a certain ...

The New Freezing of Gait Questionnaire: Unsuitable as an Outcome in Clinical Trials?

open access: yesMovement Disorders Clinical Practice, 2020
Freezing of gait (FOG) is a common gait deficit in Parkinson's disease. The New Freezing of Gait Questionnaire (NFOG‐Q) is a widely used and valid tool to quantify freezing of gait severity.
