Neuroendocrine abnormalities in Parkinson's disease
Neuroendocrine abnormalities are common in Parkinson's disease (PD) and include disruption of melatonin secretion, disturbances of glucose, insulin resistance and bone metabolism, and body weight changes. They have been associated with multiple non-motor symptoms in PD and have important clinical consequences, including therapeutics. Some of the underlying mechanisms have been implicated in the pathogenesis of PD and represent promising targets for the development of disease biomarkers and neuroprotective therapies. In this systems-based review, we describe clinically relevant neuroendocrine abnormalities in Parkinson's di...

Ischemic brain injury: new insights on the protective role of melatonin.
Abstract Stroke represents one of the most common causes of brain's vulnerability for many millions of people worldwide. The plethora of physiopathological events associated with brain ischemia are regulate through multiple signaling pathways leading to the activation of oxidative stress process, Ca2+ dyshomeostasis, mitochondrial dysfunction, proinflammatory mediators, excitotoxicity and/or programmed neuronal cell death. Understanding this cascade of molecular events is mandatory in order to develop new therapeutic strategies for stroke. In this review article, we have highlighted the pleiotropic effects of mela...

Neuroprotection of agomelatine against cerebral ischemia/reperfusion injury through an antiapoptotic pathway in rat
In this study, cerebral I/R injury rats were induced by middle cerebral artery occlusion (MCAO) for 2 h followed by reperfusion. The rats were randomly divided into 6 groups (12 rats per group): sham-operated; vehicle-treated I/R; 20 mg/kg, 40 mg/kg, and 80 mg/kg agomelatine-treated I/R; and 10 mg/kg melatonin-treated I/R. Agomelatine and melatonin were intraperitoneally administrated to the rats 1 h before MCAO induction. After reperfusion for 24 h, the brain samples were harvested for evaluating the infarct volume, histological changes, terminal deoxynucleotidyltransferase-mediated deoxyuridine triphosphate nick-e...

Protection of cardiac cell-to-cell coupling attenuate myocardial remodeling and proarrhythmia induced by hypertension.
Abstract Gap junction connexin channels are important determinants of myocardial conduction and synchronization that is crucial for coordinated heart function. One of the main risk factors for cardiovascular events that results in heart attack, congestive heart failure, stroke as well as sudden arrhythmic death is hypertension. Mislocalization and/or dysfunction of specific connexin-43 channels due to hypertension-induced myocardial remodeling have been implicated in the occurrence of life-threatening arrhythmias and heart failure in both, humans as well as experimental animals. Recent studies suggest that down-re...

Sleep Deprivation Is Killing You And Your Career
The next time you tell yourself that you'll sleep when you're dead, realize that you're making a decision that can make that day come much sooner. Pushing late into the night is a health and productivity killer. The short-term productivity gains from skipping sleep to work are quickly washed away by the detrimental effects of sleep deprivation on your mood, ability to focus, emotional intelligence, and access to higher-level brain functions for days to come. The negative effects of sleep deprivation are so great that people who are drunk outperform those lacking sleep. Why You Need Adequate Sleep to Perform We've always...

Melatonin protects against oxygen and glucose deprivation by decreasing extracellular glutamate and Nox-derived ROS in rat hippocampal slices.
Abstract Therapeutic interventions on pathological processes involved in the ischemic cascade, such as oxidative stress, neuroinflammation, excitotoxicity and/or apoptosis, are of urgent need for stroke treatment. Melatonin regulates a large number of physiological actions and its beneficial properties have been reported. The aim of this study was to investigate whether melatonin mediates neuroprotection in rat hippocampal slices subjected to oxygen-glucose-deprivation (OGD) and glutamate excitotoxicity. Thus, we describe here that melatonin significantly reduced the amount of lactate dehydrogenase released in the...

Why Every Woman Needs A Good Night's Rest
When I began writing in this spot three years ago, the headline of my very first entry was, "Getting Enough Sleep Is Smart, Not Selfish." That post went up at a time when Americans were beginning to focus more on a good night's rest. The subject came into a sharper focus, in part, because wearable technology gave us some specifics. Forget the anecdotal evidence of whether we slept well; with the touch of a button, we could know what time we fell asleep, how long we were out and how often our sleep was interrupted. The study of sleep -- and conversations around it -- began gaining traction. Among those paying keen attenti...

Vitamin D Deficiency Is As Dangerous As Smoking
The advice you’re getting from your doctor, the TV and even the Surgeon General is so wrong, it’s scary. They’re all busy telling you to stay out of the sun. But Swedish researchers recently discovered that nonsmokers who avoid the sun have a life expectancy similar to smokers who spend a lot of time in the sun. Staying out of the sun is as dangerous as smoking.1 It doesn’t surprise me. I tell all my patients sunlight exposure is essential to our health because it is the best source of vitamin D… possibly the most important nutrient we know of. Mainstream medicine still doesn’t recognize th...

The antioxidative property of melatonin against brain ischemia.
Authors: Paterniti I, Cordaro M, Esposito E, Cuzzocrea S Abstract This review briefly summarizes some of the large amount of data documenting the ability of melatonin to limit molecular and organ tissue damage in neural ischemia-reperfusion injury (stroke), where free radicals are generally considered as being responsible for much of the resulting tissue destruction. Melatonin actions that have been identified include its ability to directly neutralize a number of toxic reactants and stimulate antioxidative enzymes. Furthermore, several of its metabolites such as N(1)-acetyl-N(2)-formyl-5- methoxykynuramine (AFMK) ...

Ice Pick Headache
Abstract Ice pick headache, also called idiopathic or primary stabbing headache, is a unique headache type associated with ultra-brief stabs of pain, most commonly in the frontal or temporal area. It occurs predominantly in women and is estimated to affect 2–35 % of the population. Unlike other headache types of short duration, such as short-lasting unilateral neuralgiform headache with conjunctival injection and tearing (SUNCT), ice pick headache is not associated with any cranial autonomic symptoms but has been known to occur with nausea, vomiting, photophobia, and dizziness. It exists in two forms: primary ...

10 Sleep Technologies: How Much Snore for the Dollar?
Do you want better sleep? Of course you do. You know how bad it is to miss out on sleep, so it can feel like insult added to injury to read yet another newfound, devastating consequence of insufficient sleep: heart disease, heart attack, high blood pressure, stroke, diabetes, mental impairment, etc. And the list is expanding almost daily as researchers learn more. There are "easy" actions that may aid with sleep. Relaxation activities like meditation or chamomile tea are useful for some. Setting and sticking to a waking and sleeping schedule, creating a bedroom retreat, and making a list of worries before turning in can he...

Melatonin as an Antioxidant for Stroke Neuroprotection.
Abstract Melatonin (N-acetyl-5-methoxytryptamine) is a hormone derived from the pineal gland that has wide range of clinical application. While melatonin was originally assessed as a hormone specializing in regulation of the normal circadian rhythm in mammals, it now has been shown to be an effective free radical scavenger and antioxidant. Current research has focused on Central Nervous System (CNS) disorders, stroke in particular, for potential melatonin-based therapeutics. As of now, the realm of potential therapy regimens is focused on three main treatments: exogenously delivered melatonin, pineal gland graftin...
