Identification of ER/SR resident proteins as biomarkers for ER/SR calcium depletion in skeletal muscle cells

open access: yesOrphanet Journal of Rare Diseases, 2022
Background Aberrations to endoplasmic/sarcoplasmic reticulum (ER/SR) calcium concentration can result in the departure of endogenous proteins in a phenomenon termed exodosis.

Cannabis, medical use and related policies reflections on society (tur)

open access: yesKlinik Psikiyatri Dergisi, 2020
Cannabis is one of the important food and textile resources that has been used since 4000 BC. The fact that it was used as a medicine by the Chinese caused it to be included in the oldest pharmacopoeia in the world.

Medial prefrontal cortex and anteromedial thalamus interaction regulates goal-directed behavior and dopaminergic neuron activity

open access: yesNature Communications, 2022
The prefrontal cortex is involved in goal-directed behaviour. Here the authors show that medial prefrontal cortex activates goal-directed motivation and dopamine neurons via a feedback loop with the anteromedial thalamus.

Drug abuse in the Bahamas [PDF]

open access: yesJournal of Substance Abuse Treatment, 1985
The Bahamas is a group of islands, just off the coast of Florida, extending southwards to near the island of Hispaniola. There are approximately 25 inhabited islands and numerous small islands and cays that are uninhabited. The population of the Bahamas is approximately 230–240,000. A census taken in 1980 showed that approximately 65% of the population

Prediction of stress and drug craving ninety minutes in the future with passively collected GPS data

open access: yesnpj Digital Medicine, 2020
Just-in-time adaptive interventions (JITAIs), typically smartphone apps, learn to deliver therapeutic content when users need it. The challenge is to “push” content at algorithmically chosen moments without making users trigger it with effortful input ...

Dopamine transients do not act as model-free prediction errors during associative learning

open access: yesNature Communications, 2020
Dopamine neurons are proposed to signal the reward prediction error in model-free reinforcement learning algorithms. Here, the authors show that when given during an associative learning task, optogenetic activation of dopamine neurons causes associative,

Methylenedioxypyrovalerone (MDPV) mimics cocaine in its physiological and behavioral effects but induces distinct changes in NAc glucose

open access: yesFrontiers in Neuroscience, 2015
Methylenedioxypyrovalerone (MDPV) is generally considered to be a more potent cocaine-like psychostimulant, as it shares a similar pharmacological profile with cocaine and induces similar physiological and locomotor responses.

Whole brain dynamics during optogenetic self-stimulation of the medial prefrontal cortex in mice

open access: yesCommunications Biology, 2021
Cover et al. develop a method that permits functional MRI of brain dynamics while mice are cued to perform an operant task: licking a spout to receive optogenetic stimulation to the medial prefrontal cortex.
