Melatonin and alcohol-related disorders.

Melatonin and alcohol-related disorders. Chronobiol Int. 2020 May 18;:1-23 Authors: Kurhaluk N, Tkachenko H Abstract This review concerns the current knowledge of melatonin and alcohol-related disorders. Chronobiological effects of ethanol are related to melatonin suppression and in relation to inflammation, stress, free radical scavenging, autophagy and cancer risk. It is postulated that both alcohol- and inflammation-induced production of reactive oxygen species (ROS) alters cell membrane properties leading to tissue dysfunction and, subsequent further ROS production. Lysosomal enzymes are often used to assess the relationships between intensified inflammation states caused by alcohol abuse and oxidative stress as well as level of tissue damage estimated by the increased release of cellular enzymes into the extracellular space. Studies have established a link between alcoholism and desynchronosis (circadian disruption). Desynchronosis results from the disorganization of the body's circadian time structure and is an aspect of the pathology of chronic alcohol intoxication. The inflammatory conditions and the activity of lysosomal enzymes in acute alcohol poisoning or chronic alcohol-dependent diseases are in most cases interrelated. Inflammation can increase the activity of lysosomal enzymes, which can be regarded as a marker of lysosomal dysfunction and abnormal cellular integrity. Studies show alcohol toxicity is modulated by the melatonin (Mel) circad...

According to the latest numbers, roughly 9 million Americans — 4% of U.S. adults — use prescription sleep aids, or medications that can help with insomnia and other sleep issues. And now, some of the most popular prescription sleep drugs must carry stronger safety warnings. In April, the Food and Drug Administration (FDA) mandated black-box warnings — which the agency uses to “call attention to serious or life-threatening risks” — on three sedative-hypnotic sleep aids: eszopiclone (often sold under the brand name Lunesta), zaleplon (Sonata) and zolpidem (Ambien). Hypnotic drugs, which ar...

How many addictions do you currently have? Are you addicted to smoking, caffeine, sugar, alcohol, any other drugs, the Internet, porn, masturbation, sex, orgasm, gambling, shopping, work, TV, movies, social media, video games, food, or anything else? What behaviors do you perform compulsively, even though they don’t really serve you in the long run? The insidious thing about addictions is that all addictions weaken the prefrontal cortex, which is the part of your brain associated with self-discipline and willpower. The more addictions you have, the weaker your self-regulation abilities become, which increases your su...

McLean Hospital Guest Blogger Hilary Smith Connery, MD, PhD Self-inflicted injury is now the 8th leading cause of mortality, while suicide is the 10th leading cause of death in the United States. That's a stunning number of people dying by their own hand in one form or another, and in addition to galvanizing public health prevention efforts, these statistics pose an urgent need to identify root causes and more effective treatment systems. Treatment works, but beyond having access to appropriate medical and psychological help, the social environment is critical to creating successful recovery opportunities for those suff...

It’s fair to say that 2016 wasn’t a popular year (to put it mildly). But while we may be ready to embrace 2017 with open arms, there’s one mistake many of us will probably bring into the New Year: focusing on the wrong resolution. If data published in 2015 is any indication, many of us will pledge to lose weight. However, the problem with focusing solely on the scale is that it isn’t necessarily beneficial or indicative of our well-being. Not to mention the fact that concentrating on a pants size may make us ignore all the other aspects of wellness (like self-esteem or empathy, for example). Of...

ConclusionThe study brings together evidence in support of a plausible theory about the causes of migraine. However, the evidence is very mixed in quality. Although the author says all triggers have the potential to cause oxidative stress, the link for some triggers is quite weak. For example, he says in the study it is unclear whether excessive mental work can cause oxidation, and that the role of oestrogen is not clear. Because of the difficulty of showing the effects of oxidative stress on the brain, most of the evidence is from animal studies on mice or rats, or studies of what happens to cells in test tubes or petri d...

FALL CITY, Wash. -- When Roey Gabay finally got home from the college library, he found his twin sister, Reut, waiting for him in the living room. It was around 1 a.m. on June 9, the night before finals. But she knew he hadn't gone to the library to study. And he knew she knew it. "Come here," she said, as Gabay tried to make a beeline for his bedroom in their house by the California State University, East Bay, campus. "We need to talk." Months later, Gabay, 20, could still remember the tears in his sister's eyes that night, and how he sensed what was about to happen. After years of watching him blow of...

“TREE OF HOPE” Breast Cancer Survivor Tree I found out I had breast cancer on June 11th 2014. I had a double mastectomy on July 3rd 2014. I am 4 months out from surgery and I am feeling great. However, as you might imagine, it was no walk in the park. Lots of emotional upheaval. Lots of physical difficulty. But with great support from friends, family and good health care workers I’m doing very well. Over the last 4 months I have spent most of my free time learning about cancer and in particular breast cancer, what causes it and what cures it.  Before my diagnosis, it never crossed my mind that I...
