Ovarian hormones, such as estrogens and progesterone, are known to exert beneficial effects on cognition and some psychiatric disorders. The basis of these effects is not fully understood, but may involve altered cholinergic neurotransmission. This study

Jasminum bioactives improve food preservation by providing antimicrobial and antioxidant effects, especially when incorporated into active packaging, edible films, and nanoformulations that enhance stability and controlled release. They also offer many pharmacological benefits, including anti‐inflammatory, neuroprotective, and wound‐healing properties.

Effect of Neuromodulation of Short-Term Plasticity on Information Processing in Hippocampal Interneuron Synapses [PDF]
Neurons in a micro-circuit connected by chemical synapses can have their connectivity affected by the prior activity of the cells. The number of synapses available for releasing neurotransmitter can be decreased by repetitive activation through depletion of readily releasable neurotransmitter (NT), or increased through facilitation, where the ...

Weakly Coupled Oscillators in a Slowly Varying World [PDF]
We extend the theory of weakly coupled oscillators to incorporate slowly varying inputs and parameters. We employ a combination of regular perturbation and an adiabatic approximation to derive equations for the phase-difference between a pair of oscillators. We apply this to the simple Hopf oscillator and then to a biophysical model.

Cholinergic neurons play an important role in the higher functions of the brain, such as the memory, cognition, and nociception. However, the exact mechanism behind how the stimulation of all the muscarinic M1 receptors in the entire brain results in the

Cholinergic System Changes in Dopa‐Unresponsive Freezing of Gait in Parkinson's Disease
Abstract Background Freezing of gait (FoG) is a debilitating mobility disturbance that becomes increasingly resistant to dopaminergic pharmacotherapies with advancing Parkinson's disease (PD). The pathophysiology underlying the response of FoG to dopaminergic treatment is poorly understood.

Altruism and Antagonistic Pleiotropy in Penna Ageing Model [PDF]
The Penna ageing model is based on mutation accumulation theory. We show that it also allows for self-organization of antagonistic pleiotropy which helps at young age at the expense of old age. This can be interpreted as emergence of altruism.

Light‐Activated Pharmacological Tools for Exploring the Cholinergic System
ABSTRACT Cholinergic transmission plays a critical role in both the central and peripheral nervous systems, affecting processes such as learning, memory, and inflammation. Conventional cholinergic drugs generally suffer from poor selectivity and temporal precision, leading to undesired effects and limited therapeutic efficacy. Photopharmacology aims to
