Deep brain stimulation (DBS), an effective neurosurgical therapy for Parkinson's disease (PD), may act via eliciting neurotransmitter release. However, the precise relationships between DBS and neurotransmitter release are not established. One issue in these studies may be analytical limitations of microdialysis and positron emission tomography, the primary measurement technologies employed. Limitations may be overcome by microsensors, which exhibit improved temporal and spatial resolution. Here we assess fast-scan cyclic voltammetry (FSCV) at a carbon-fiber microelectrode (CFM) for monitoring a putative DBS neurotransmitter, dopamine, during stimulation of the subthalamic nucleus (STN), a DBS target for PD. These results, obtained in the anesthetized rat, suggest that real-time microsensors are a suitable approach for testing the neurotransmitter release hypothesis of DBS action.

Actin, a ubiquitous and highly conserved cytoskeletal protein, plays a pivotal role in various cellular functions such as structural support, facilitating cell motility, and contributing to the dynamic processes of synaptic function. Apart from its established role in inducing morphological changes, recent developments in the field indicate an active involvement of actin in modulating both the structure and function of pre- and postsynaptic terminals. Within the presynapse, it is involved in the organization and trafficking of synaptic vesicles, contributing to neurotransmitter release.

Significance: Women are at increased risk for mood disorders, which may be partly attributed to exposure to endocrine-disrupting chemicals (EDCs) during sensitive periods such as pregnancy. Exposure during these times can impact brain development in the offspring, potentially leading to mood disorders in later life. Additionally, fluctuating levels of endogenous estrogens, as seen during pregnancy, or the use of oral contraceptives, can further elevate this risk.

Background: Doxepin (DX) is used orally to relieve itching but can cause side effects like blurred vision, dry mouth, and drowsiness due to its antimuscarinic effect. To reduce these adverse effects and improve skin permeation, DX is being developed in topical formulations. This study aims to improve DX skin absorption by developing a microemulsion (ME) formulation (ME-DX).

The evolution of brain-expressed genes is notably slower than that of genes expressed in other tissues, a phenomenon likely due to high-level functional constraints. One such constraint might be the integration of information by neuron assemblies, enhancing environmental adaptability. This study explores the physiological mechanisms of information integration in neurons through three types of synchronization: chemical, electromagnetic, and quantum.

The beneficial properties of probiotics have always been a point of interest. Probiotics play a major role in maintaining the health of Gastrointestinal Tract (GIT), a healthy digestive system is responsible for modulating all other functions of the body. The effectiveness of probiotics can be enhanced by formulating them with prebiotics the formulation thus formed is referred to as synbiotics.
