Electrocatalytic Dehydrogenative Lactonization of Benzylic Alcohols: A Sustainable Access to Phthalides via N‐hydroxyphthalimide Mediation

Advanced Synthesis &Catalysis, EarlyView.
A mild, scalable electrocatalytic method for direct lactonization of benzylic alcohols to phthalides using N‐hydroxyphthalimide as a redox mediator is reported. This metal‐free process proceeds via a phthalimide‐N‐oxyl‐mediated hydrogen atom transfer mechanism, shows broad scope with good to excellent yields, and enables late‐stage functionalizations ...

Regular versus Irregular Exercise Differentially Modulates Hippocampal‐Hepatic Acetylcholine Flux to Coordinate Fear Memory Extinction and Liver Inflammation

Advanced Science, EarlyView.
Ma et al. report the hippocampal and hepatic acetylcholine (ACh) levels are differently modulated by regular versus irregular exercise, which contributes to coordinate hippocampal astrocyte activity and hepatic FBXL6high neutrophil recruitment. This ACh‐modulated brain‐liver circuit links the effects of exercise on fear memory extinction and liver ...

Time‐Dependent Therapeutic Effect of S‐Ketamine on PTSD Mediated by VTA‐OFC Dopaminergic Neurocircuit

Advanced Science, EarlyView.
This study reveals that early rather than late administration of S‐ketamine can ameliorate PTSD symptoms. This phenomenon is attributed to reversing the progressive inhibition of VTADA neurons and the function of VTADA‐OFC circuit following stress. Targeted stimulation of the OFC by TI‐NIBS to enhance DA release effectively extends the therapeutic time

Plasma norepinephrine in stroke. [PDF]

Stroke, 1981
Cardiac arrhythmias, myocardial necrosis and ECG abnormalities in stroke may result from abnormally high levels of sympathetic activity. To examine this possibility, plasma norepinephrine, epinephrine and dopamine were measured in 74 patients with cerebral infarction, 18 with transient ischemic attacks and 33 non-stroke controls.

Sleep Deprivation Aggravates Periodontitis Through Trigeminal‐Periodontal Neuroimmune Pathway Mediated by the AChE‐ACh‐α7nAChR Axis

Advanced Science, EarlyView.
Sleep deprivation (SD) exacerbates ligature‐induced periodontitis (LIP) through the trigeminal nerve‐periodontal neuroimmune pathway mediated by the acetylcholinesterase (AChE)‐acetylcholine (ACh)‐α7 nicotinic receptor (α7nAChR) axis. While electroacupuncture (EA) alleviates the condition of LIP combined with SD by activating the α7nAChR.

What's a brain: neuroanatomy and neurochemistry of anxiety disorders in dogs [PDF]

, 2011
This review deals with the neurocircuitry of fear and anxiety disorders, with the focus on neuroanatomy and neurochemistry. This knowledge is required to correctly diagnose and treat dogs with anxiety-related behavioral disorders.

Potentiating Cerebral Perfusion Normalizes Glymphatic Dynamics in Systemic Inflammation

Advanced Science, EarlyView.
LPS‐induced systemic inflammation increases glymphatic influx but delays cervical lymphatic drainage, accompanied by AQP4 depolarization and impaired glymphatic clearance. Enhancing cerebral blood flow via the inotropic agent levosimendan effectively restored AQP4 polarization, improving glymphatic flux and amyloid‐β clearance.

Autophagy-Based Hypothesis on the Role of Brain Catecholamine Response During Stress

Frontiers in Psychiatry, 2020
Stressful events, similar to abused drugs, significantly affect the homeostatic balance of the catecholamine brain systems while activating compensation mechanisms to restore balance.

State-Dependent Subnetworks of Parvalbumin-Expressing Interneurons in Neocortex. [PDF]

, 2019
Brain state determines patterns of spiking output that underlie behavior. In neocortex, brain state is reflected in the spontaneous activity of the network, which is regulated in part by neuromodulatory input from the brain stem and by local inhibition ...
