Potential neuroprotective and therapeutic agents and their mechanisms for irradiation‐induced brain injury

Ibrain, EarlyView.
In this review, agents such baicalein, troxerutin, epigallocatechin gallate, quercetin, melatonin, valproic acid, lithium, neurosteroid progesterone, as well as minocycline have been implicated as neuroprotective agents for irradiation‐induced neurological deficits. Also, agents such as glucocorticoids, methylphenidate, vitamin E, bisdemethoxycurcumin,

White Matter Dysfunction and Neurotransmitter Basis Underlying the Freezing of Gait in Parkinson's Disease

iNew Medicine, EarlyView.
In the freezing of gait in Parkinson's disease, white matter shows decreased local activity but increased functional connectivity. These distinct dysfunctions are uniquely associated with specific neurotransmitter systems (GABA, dopamine, etc.), mapping a new neurochemical basis for this debilitating symptom. ABSTRACT Freezing of gait (FOG) is a severe

Untreated Giant Macroprolactinoma with Chronic Cerebrospinal Fluid Leakage: An Unusual Complication

Case Reports in Endocrinology, 2019
Macroprolactinoma has the potential to cause base of skull erosion and often extends into the sphenoid sinus. Rapid shrinkage of this invasive tumor following dopamine agonist therapy has been postulated to cause unplugging of the eroded area, leading to

Sex-based disparities in dopamine agonist response in patients with restless legs syndrome. [PDF]

J Sleep Res
Summary This study aimed to investigate sex‐related differences in the response to ropinirole and pramipexole in patients with restless legs syndrome (RLS). By analysing clinical parameters and polysomnographic (PSG) findings, we sought to elucidate the potential factors related to sex disparities modulating treatment responses and sleep quality in RLS.

A novel octopamine receptor with preferential expression in Drosophila mushroom bodies [PDF]

, 1998
Octopamine is a neuromodulator that mediates diverse physiological processes in invertebrates. In some insects, such as honeybees and fruit flies, octopamine has been shown to be a major stimulator of adenylyl cyclase and to function in associative ...

The effects of pioglitazone, a PPARγ receptor agonist, on the abuse liability of oxycodone among nondependent opioid users [PDF]

, 2016
Aims: Activation of PPARγ by pioglitazone (PIO) has shown some efficacy in attenuating addictive-like responses in laboratory animals. The ability of PIO to alter the effects of opioids in humans has not been characterized in a controlled laboratory ...
