Establishing In-vivo brain microdialysis for comparing concentrations of a variety of cortical neurotransmitters in the awake rhesus macaque between different cognitive states.

Background: Neuronal activity is modulated by behavior and cognitive processes. The combination of several neurotransmitter systems, acting directly or indirectly on specific populations of neurons, underlie such modulations. Most studies with non-human primates (NHPs) fail to capture this complexity, partly due to the lack of adequate methods for reliably and simultaneously measuring a broad spectrum of neurotransmitters while the animal engages in behavioral tasks.

Brain network correlates of affective symptoms in aMCI.

Affective symptoms (i.e., depression, anxiety, and apathy) are the most prevalent subsyndrome of neuropsychiatric symptoms (NPS) in preclinical dementia, such as amnestic mild cognitive impairment (aMCI), and remain a challenge to understand and treat.

Modeling bladder mechanics with 4D reconstruction of murine ex vivo bladder filling.

This study presents a novel methodology for high-resolution 3D bladder modeling during filling, developed by leveraging improved imaging and computational techniques. Using murine bladder filling data, the methodology generates accurate 3D geometries across time, enabling in-depth mechanical analysis. Comparison with a traditional spherical model revealed similar stress trends, but the 3D model permitted nuanced quantifications, such as localized surface curvature and stress analysis.

Tracheobronchopathia osteochondroplastica as an unusual cause of chronic cough.

A cough that persists for more than 8 weeks is defined as a chronic cough. In routine practice, asthma, gastroesophageal reflux disease, and postnasal drip are the most common causes of chronic cough. A 58-year-old non-smoking male patient with no known comorbidities presented with a 3-month history of non-productive cough.
