Micro‐Stimulation Timing Framed Around an Averaged Theta Period of Stimulation Determines Hippocampal Recruitment in Cued Fear Conditioning

open access: yesHippocampus, Volume 36, Issue 3, May 2026.
ABSTRACT The importance of precise timing of neuronal activity, relative to ongoing slower oscillations, is reshaping the engram theory and our understanding of how memories are encoded and stored. The hippocampal theta‐wave phase‐encoding of neuronal firing predicts behavioral outcomes and cognitive performance in memory tasks.

Cryopreservation of Chlorella vulgaris Using Different Cryoprotectant Agents

open access: yesJournal of Agricultural Science, 2020
The objective of this study is to evaluate the cryopreservation of Chlorella vulgaris using different substances. The C. vulgaris was cultured in medium MH, the microalgae were grown under a 12:12 h light: dark photoperiod, illumination with 40 W led lamps, and a controlled temperature of 28±1 ºC. C.vulgaris was cultured for 15 days

Protective Effect of Intracellular Compounds of Lactobacillus plantarum on Goat Sperm Quality During Cryopreservation

open access: yesVeterinary Medicine and Science, Volume 12, Issue 3, May 2026.
Intracellular compounds from Lactobacillus plantarum were added to a goat sperm cryopreservation extender. A concentration of 20 µL/mL improved post‐thaw sperm quality, whereas higher concentrations (80–100 µL/mL) had detrimental effects. ABSTRACT Background Cryopreservation of sperm is a key strategy for preserving and transmitting the genetic traits ...

Effects of cryoprotectant concentration and cooling rate on vitrification of aqueous solutions

open access: yes, 2006
Vitrification of aqueous cryoprotectant mixtures is essential in cryopreservation of proteins and other biological samples. We report systematic measurements of critical cryoprotective agent (CPA) concentrations required for vitrification during plunge ...

TRP canonical 4 and/or 5 channel inhibition reduces aversion‐ and increases reward‐responding in chronically stressed mice

open access: yesBritish Journal of Pharmacology, Volume 183, Issue 9, Page 2139-2165, May 2026.
Abstract Background and Purpose Pharmacological inhibition of TRPC4 and/or TRPC5 channels reduces Pavlovian aversion memory in stressed mice and reduces amygdala reactivity to aversion in humans with depression. The aims of this mouse study were to improve understanding of these anxiolytic processes, determine whether there are corrective effects on ...
