SummaryBackground: Although it is generally accepted that there is an increased oxidative stress status in alcoholics, the separate relevance of oxidative stress following alcohol withdrawal is still not understood to this date. There are reports stating that the increased oxidative stress status in alcoholics may persist independently of the constant presence of alcohol intake, while on the other side, it was demonstrated that the antioxidant defense mechanism could significantly increase after alcohol withdrawal. Methods: In the present work, we were interested in studying the relevance of oxidative stress status in the alcohol withdrawal processes, by determining some oxidative stress markers (two antioxidant enzymes: superoxide dismutase -SOD and glutathione peroxidase -GPX and a lipid peroxidation maker -MDA) after one week and one month of abstinence, as compared to the baseline and a control group of subjects. Results: Our data confirmed the increased oxidative stress status in alcoholic patients and, more importantly, we de monstrated here a significant decrease of the oxidative stress status one week and one month following the withdrawal, as showed by a significant increase in the specific activity of
There is increased interest in the interactions between vascular disorders
and Alzheimer?s disease (AD). While initially these interactions were
explained by the fact that these are both very common disorders, particularly
later in life, recently, the possibility that these deficiencies might
actually coexist is increasingly being questioned. This review attempts to
present modern aspects and current reports regarding the interactions between
AD, the renin-angiotensin system (RAS) and hypertension, while also
describing the relevance of antihypertensive drug use acting via the RAS in
the treatment and prevention of AD, as well as the importance of oxidative
stress, the alteration of the balance between antioxidants and pro-oxidants,
in the interaction between AD and the RAS.
Although the therapeutic potential of virtual reality has been foreseen since over half a century ago, the lack of graphical processing power made it impossible to apply in medical therapeutic sciences until last decade; nowadays, the hardware required for virtual reality is even 100 times more affordable. A head-mounted display induces immersivity engulfing the subject’s eyesight perception in a stereoscopic manner. The same tool that may aid better self understanding and bonding can also trigger psychopathological mechanisms through which the user becomes alienated from the real world. As virtual reality became even more popular during SARS-COV2 pandemic, users worldwide have spent more time into a virtual world. Depersonalization/derealization syndrome can occur if virtual reality is abused. The greater the person’s involvement in virtual reality, the greater the chance of a lack of bodily self (depersonalization). Controllers that mimic hands could prevent the subject from acknowledging the real world as true – derealization. Virtual reality’s dissociative potential is related to individual psychological traits and prolonged exposure. Children are the most prone to develop behavioral changes. Adults may develop behavioral problems related to virtual reality gaming, gambling, pornography and also social networking through created avatars. Blue light wavelength could harm sleep architecture and circadian rhythm by disrupting melatonin, therefore making virtual reality exposure problematic after sunset. State of the art reveals that using virtual reality in a therapeutic manner, actually facilitates the fight against addictions with cue therapy intended to extinguish conditioned response. The exposure to a substance (nicotine, alcohol, or any other psychoactive recreational abuse potential substances) can trigger craving in a controlled environment, that is malleable in the hands of the therapist. Virtual reality can offer an exposure perspective that is both vivid enough to be a challenge, but also safe enough to ensure patient involvement and to amplify the therapeutic alliance.
While the exact relevance of the oxidative stress markers after the complex processes of alcohol withdrawal is still controversial, in the present report we were interested in studying the relevance of oxidative stress status in the alcohol withdrawal processes, by determining some oxidative stress markers after 3, 6 and 12 months of abstinence. 62 patients were selected, all of them males. Thus, 33 (baseline), 14 (3 months), 14 (6 months)
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
