Abnormal hippocampal melatoninergic system: a potential link between absence epilepsy and depression-like behavior in WAG/Rij rats? [PDF]

open access: yes, 2018
Absence epilepsy and depression are comorbid disorders, but the molecular link between the two disorders is unknown. Here, we examined the role of the melatoninergic system in the pathophysiology of spike and wave discharges (SWDs) and depression-like ...

A Systematic Review on Disease‐Modifying Therapies in Parkinsonian Disorders

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
Parkinsonian disorders, including Parkinson's disease, Lewy body dementia, multiple system atrophy, and progressive supranuclear palsy, are progressive neurodegenerative conditions with no treatment options to slow disease progression. This systematic review provides an overview of evidence of disease‐modifying therapies that have been evaluated in ...

Melatonin reduces LH, 17 beta-estradiol and induces differential regulation of sex steroid receptors in reproductive tissues during rat ovulation

open access: yesReproductive Biology and Endocrinology, 2011
Background Melatonin is associated with direct or indirect actions upon female reproductive function. However, its effects on sex hormones and steroid receptors during ovulation are not clearly defined. This study aimed to verify whether exposure to long-

Dysfunctional Light-Evoked Regulation of cAMP in Photoreceptors and Abnormal Retinal Adaptation in Mice Lacking Dopamine D4 Receptors [PDF]

open access: yes, 2002
Dopamine is a retinal neuromodulator that has been implicated in many aspects of retinal physiology. Photoreceptor cells express dopamine D4 receptors that regulate cAMP metabolism.

Ambient technology in epilepsy clinical practice

open access: yesEpilepsia Open, EarlyView.
Abstract The utilization of large language model‐based artificial intelligence (AI) in the field of neurology has gained attention as a viable tool to enhance and assist providers with processes ranging from scheduling patients to providing preliminary interpretations of testing results, pending orders, and documenting encounters. Epileptologists could

Absence seizures: Update on signaling mechanisms and networks

open access: yesEpilepsia Open, EarlyView.
Abstract Absence seizures (AS) are a hallmark of genetic generalized epilepsies (GGE), characterized by brief episodes of impaired consciousness accompanied by electroencephalographic spike‐and‐wave discharges (SWDs). Traditionally attributed to cortico‐thalamo‐cortical (CTC) dysrhythmia, emerging evidence suggests a more intricate pathophysiological ...

The Pineal Gland and Breast Cancer: Serum Levels of Melatonin in Patients with Mammary Tumors and Their Relation to Clinical Characteristics

open access: yesThe International Journal of Biological Markers, 1989
Several studies have suggested that the pineal gland hormone melatonin may influence the growth of breast cancer. The importance of melatonin blood concentrations in the clinical history of human breast cancer, however, has still to be defined.

Short photoperiod-induced decrease of histamine H3 receptors facilitates activation of hypothalamic neurons in the Siberian Hamster [PDF]

open access: yes, 2009
Nonhibernating seasonal mammals have adapted to temporal changes in food availability through behavioral and physiological mechanisms to store food and energy during times of predictable plenty and conserve energy during predicted shortage.

Prenatal betamethasone–postnatal N‐methyl‐D‐aspartic acid model of spasms: Update on mechanisms and treatments

open access: yesEpilepsia Open, EarlyView.
Abstract Infantile epilepsy spasms syndrome (IESS), formerly known as infantile spasms or West Syndrome, is a severe epilepsy syndrome affecting about 3 in 10,000 newborns in the United States. Characterized by clusters of epileptic spasms, interictal hypsarrhythmia, and developmental delays, IESS has diverse causes, including structural‐metabolic ...
