BACKGROUND: In an article published in International Journal of the Addictions in 1989, Nick Piazza and his coauthors described "telescoping," an accelerated progression through "landmark symptoms" of alcoholism, among a sample of recovering women. OBJECTIVES: The aim of this critical analysis is to apply a feminist philosophy of science to examine the origins of the framework of telescoping research and its implications for contemporary scientific inquiry. METHODS: A feminist philosophy of science framework is outlined and applied to key source publications of telescoping literature drawn from international and United States-based peer-reviewed journals published beginning in 1952...

On-target drug delivery remains a challenge in cancer precision medicine; it is difficult to deliver a targeted therapy to cancer cells without incurring toxicity to normal tissues. The SERCA (sarco-endoplasmic reticulum Ca(2+) ATPase) inhibitor thapsigargin inhibits mutant NOTCH1 receptors compared with wild type in T cell acute lymphoblastic leukemia (T-ALL), but its administration is predicted to be toxic in humans. Leveraging the addiction of ALL to folic acid, we conjugated folate to an alcohol derivative of thapsigargin via a cleavable ester linkage...

Alcohol use disorder is a detrimental addictive disease that develops through prolonged ethanol exposure and regular intoxication. However, the changes in the underlying neurobiology leading to alcohol addiction remain unclear. Brain-Derived Neurotrophic Factor (BDNF) is implicated in substance abuse disorders including alcoholism. As the vast majority of previous animal model studies have concentrated on males only, the aim of this study was to determine whether endogenous BDNF mediates alcohol seeking in a sex-specific manner...

PURPOSE: Substance use has been linked to the sexual transmission of HIV among gay, bisexual, and other men who have sex with men (MSM) across the lifespan. Among older, HIV-positive, MSM populations, cognitive dysfunction associated with age and HIV disease progression also may play a role in sexual risk-taking. People aged 50 years and older represent a growing proportion of the overall HIV-positive population. This study aimed to explore relationships between substance use and cognitive function, and their impact on condomless anal sex (CAS) among HIV-positive gay, bisexual, and other MSM aged 50 years and older...

Difficulties in emotion regulation are commonly reported among individuals with alcohol and drug addictions and contribute to the acquisition and maintenance of addictive behaviors. Alterations in neural processing of negative affective stimuli have further been demonstrated among individuals with addictions. However, it is unclear whether these alterations are a general feature of addictions or are a result of prolonged exposure to drugs-of-abuse. To test the hypothesis of altered negative affect processing independent of drug effects, this study assessed neural function among drug-naïve youth with a behavioral addiction-Internet gaming disorder (IGD)...

DNA repair mechanisms allow maintain genomic stability and proper functioning within the cells. Any aberrations may cause an increased risk of many diseases such as cancer. The most crucial risk factors for head and neck squamous cell carcinoma are behavioral factors, predominantly chronic exposure to tobacco, alcohol addiction, and infection with human papillomavirus or Epstein-Barr virus. These agents can induce DNA damage; therefore, cells must activate appropriate mechanisms in order to function correctly...

Adult neurogenesis, a complex process by which stem cells in the hippocampal brain region differentiate and proliferate into new neurons and other resident brain cells, is known to be affected by many intrinsic and extrinsic factors, including diet. Neurogenesis plays a critical role in neural plasticity, brain homeostasis, and maintenance in the central nervous system and is a crucial factor in preserving the cognitive function and repair of damaged brain cells affected by aging and brain disorders. Intrinsic factors such as aging, neuroinflammation, oxidative stress, and brain injury, as well as lifestyle factors such as high-fat and high-sugar diets and alcohol and opioid addiction, negatively affect adult neurogenesis...

This perspective piece gives an overview of the current situation of yoga therapy in Japan today. Traditional yoga in Japan suffered a serious setback in 1995 with a nerve gas terrorist attack on the Tokyo subway, which was carried out by a cult that recruited members through yoga classes. But with the increase in popularity with modern forms of yoga such as Iyengar yoga, Ashtanga yoga and hot yoga in the West, the general public in Japan today is forgetting its aversion to yoga and considers it to be something that can contribute to good health...

BACKGROUND: The MoCA score is a convenient and promising tool for estimating alcoholic patients' global cognitive functioning, a major challenge for all specialized alcohol treatment centers. However, whether or not the score should be corrected for education level and whether the proposed cutoff is relevant in patients with alcohol use disorders (AUD) should be determined. DESIGN: We compared the MoCA scores in patients hospitalized for AUD with and without cognitive impairment (CI) assessed by a battery of neuropsychological tests...

Excessive alcohol intake induces an inflammatory response in the brain, via TNFα, TLR4 and NF-κB signaling pathways. It has been proposed that neuroinflammation would play a very important role in the development of alcohol addiction. In addition to stimulating the synthesis of inflammatory mediators such as IL-6, IL-1β and TNFα, NF-κB is capable of reducing the anti-inflammatory activity of PPARα and PPARγ. Reciprocally, PPARα, PPARγ and melanocortin 4 receptor (MC4R) can decrease the proinflammatory activity of NF-κB, establishing an interplay of inactivations between such nuclear factors and receptors...

Addiction to cocaine is commonly preceded by experiences with legal or decriminalized drugs, such as alcohol, nicotine, and marijuana. The biological mechanisms by which these gateway drugs contribute to cocaine addiction are only beginning to be understood. We report that in the rat, prior alcohol consumption results in enhanced addiction-like behavior to cocaine, including continued cocaine use despite aversive consequences. Conversely, prior cocaine use has no effect on alcohol preference. Long-term, but not short-term, alcohol consumption promotes proteasome-mediated degradation of the nuclear histone deacetylases HDAC4 and HDAC5 in the nucleus accumbens, a brain region critical for reward-based memory...

BACKGROUND: Although there is extensive evidence that problematic alcohol use is associated with smaller hippocampal volume, the typical cross-sectional study design cannot determine whether hippocampal deviations reflect pre-existing liability toward problematic alcohol use or instead reflect an alcohol exposure-related effect. We used the co-twin control study design, which capitalizes upon differences within a twin pair in levels of drinking, to differentiate pre-existing liability from an effect of alcohol exposure...
