Complaints of sleep disturbances are common among alcohol dependent patients during subacute abstinence. Recovered patients may show persistent sleep abnormalities for months or even years. In the present study we studied the issue whether periodic limb movements in sleep and disturbances of nocturnal respiration are more frequent in alcohol dependent patients than healthy subjects and may be of predictive value for sustained abstinence vs. relapse after withdrawal. Forty alcohol dependent patients spent three nights in the sleep laboratory at three time points: 2 to 3 weeks after withdrawal (T0) and at follow-up investigations 6 (T1) and 12 (T2) months after discharge from the hospital. Measurements of PLMS-arousal index and nocturnal respiration were performed during the first laboratory night of each measurement point. Alcohol dependent patients displayed a significantly enhanced PLMS-arousal index at T0 compared to age- and gender-matched healthy subjects, whereas no alterations of nocturnal respiration were found.The PLMS-arousal index at T0 was significantly elevated in patients who relapsed during the next 6 months compared to abstinent patients. In a discriminant function analysis the PLMS-arousal index classified 55 % of the patients correctly with respect to outcome after 6 months. It correctly predicted 80 % of abstainers and 44 % of the patients who relapsed. According to neurobiological models of the generation of PLMS and the etiopathology of alcohol dependence a genetically determined vulnerability of the dopaminergic system is discussed as a factor underlying an increased risk of relapse in a subgroup of alcohol dependent patients.

Background: Nanodrugs play a crucial role in biomedical applications by enhancing drug delivery. To address safety and toxicity concerns associated with nanoparticles, lipid-nanocarrier-based drug delivery systems have emerged as a promising approach for developing next-generation smart nanomedicines. Ginseng has traditionally been used for various therapeutic purposes, including antiviral activity.

It is observed that the global burden of diseases had shifted from infectious diseases to Non-Communicable Diseases (NCDs), with an accumulative trend in developing countries. NCDs share key modifiable behavioral risk factors like unhealthy diet and lack of physical activity that are typically established during adolescence or young adulthood and will set the stage for NCDs development later in life. Therefore, this paper aimed to explore factors contributing to the co-occurrence of risk factors for NCDs among persons aged 30 years and above in selected urban areas of Namibia.

Substance Use Disorder (SUD) is a medical condition where an individual compulsively misuses drugs or alcohol despite knowing the negative consequences. The anterior cingulate cortex (ACC) has been implicated in various types of SUDs, including nicotine, heroin, and alcohol use disorders. Our research aimed to investigate the effects of deep brain stimulation (DBS) in the ACC as a potential therapeutic approach for morphine use disorder.

Many patients with diabetes use self-measurement devices for blood glucose to understand their blood glucose levels. Most of these devices utilize FAD-dependent glucose dehydrogenase (FAD-GDH) to determine blood glucose levels. For this purpose, FAD-GDHs specifically oxidizing glucose among the sugars present in blood is required.

Alcohol use disorder is associated with altered function of cortical-amygdala-striatal circuits such as the orbitofrontal cortex (OFC), basolateral amygdala (BLA) and their connections to the dorsal medial striatum (DMS) shown to be involved in goal-directed actions. Using retrobead tracing, we previously reported enhanced excitability of DMS-projecting OFC neurons in mice following 3-to-7-day withdrawal from chronic intermittent ethanol (CIE) exposure. In the same animals, spiking of DMS-projecting BLA neurons was decreased at 3-days post-withdrawal followed by an increase in firing at 7- and 14-days.
