The gut-brain axis: Unveiling the impact of xenobiotics on neurological health and disorders.

The Gut-Brain Axis (GBA) is a crucial link between the gut microbiota and the central nervous system. Xenobiotics, originating from diverse sources, play a significant role in shaping this interaction. This review examines how these compounds influence neurotransmitter dynamics within the GBA.

Assessing correlation between different temporary restorative materials for microleakage following endodontic treatment: an in-vitro study.

Background: Coronal microleakage, the passage of fluids and bacteria through the interface between the temporary restoration and the tooth structure, can potentially result in endodontic treatment failure.

Purpose: This study evaluated and compared the sealing efficacy of various temporary restorative materials utilized during endodontic procedures.

Methods: All seventy premolar teeth were extracted, measured, and restored, except for the negative control group, where the teeth were left whole.

Lead-free perovskite solar cell based on methyl ammonium tin iodide: Possible power conversion efficiency enhancement by device simulation.

Although solar cells have the potential to create an endless amount of electrical power, their comparatively low power conversion efficiency draws the curiosity of both academics and industry. The primary goal of this research is to examine the performance of lead-free perovskite solar cells that use methyl ammonium tin iodide (CHNHSnI) as the active material. The SCAPS-1D programme is employed for the simulation and analysis of the solar cells.

Emerging biophysical techniques for probing synaptic transmission in neurodegenerative disorders.

Plethora of research has shed light on the critical role of synaptic dysfunction in various neurodegenerative disorders (NDDs), including Alzheimer's disease (AD), Parkinson's disease (PD), Amyotrophic lateral sclerosis (ALS), and Huntington's disease (HD). Synapses, the fundamental units for neural communication in the brain, are highly vulnerable to pathological conditions and are central to the progression of neurological diseases. The presynaptic terminal, a key component of synapses responsible for neurotransmitter release and synaptic communication, undergoes structural and functional alterations in these disorders.
