Hepatocyte-derived extracellular vesicles regulate liver regeneration through a negative feedback mechanism.

While significant progress has been made in understanding various aspects of liver regeneration, the molecular mechanisms responsible for the initiation and termination of cell proliferation in the liver following massive tissue loss or injury of liver remain unknown. As it was previously shown, the loss of liver mass affects putative hepatocyte-specific mitogenic inhibitors in the blood. Although the presence of these putative inhibitors regulating precise liver regeneration has been described in numerous publications, they have never been identified.

Hepatocyte-derived extracellular vesicles regulate liver regeneration after partial hepatectomy.

While significant progress has been made in understanding different aspects of liver regeneration, the molecular mechanisms responsible for the initiation and termination of cell proliferation in the liver after massive loss or injury of liver tissue remain unknown. The loss of liver mass affects tissue-specific mitogenic inhibitors in the blood, which in turn regulate the proliferation of remaining hepatocytes and liver regeneration. Although well described in a number of publications, which inhibitory substances or "sensor molecules" control the regeneration mechanisms to properly maintain liver size remain unknown.

Uncoupled nitric oxide synthase activity promotes colorectal cancer progression.

Increased levels of reactive oxygen/nitrogen species are one hallmark of chronic inflammation contributing to the activation of pro-inflammatory/proliferative pathways. In the cancers analyzed, the tetrahydrobiopterin:dihydrobiopterin ratio is lower than that of the corresponding normal tissue, leading to an uncoupled nitric oxide synthase activity and increased generation of reactive oxygen/nitrogen species. Previously, we demonstrated that prophylactic treatment with sepiapterin, a salvage pathway precursor of tetrahydrobiopterin, prevents dextran sodium sulfate-induced colitis in mice and associated azoxymethane-induced colorectal cancer.

A mixed methods exploration of the emergence of goal orientation in medical students' individualized learning plans.

Purpose: Goal orientation (GO) describes an individual's approach to different achievement situations. Understanding the motivations and approach to achieving goals of medical students is vital with the increasing emphasis on self-directed learning. The purpose of this study was to identify themes in self-improvement reflections that relate to each GO dimension (learning, performance-prove, and performance-avoid).

Spironolactone as a potential new pharmacotherapy for alcohol use disorder: convergent evidence from rodent and human studies.

Evidence suggests that spironolactone, a nonselective mineralocorticoid receptor (MR) antagonist, modulates alcohol seeking and consumption. Therefore, spironolactone may represent a novel pharmacotherapy for alcohol use disorder (AUD). In this study, we tested the effects of spironolactone in a mouse model of alcohol drinking (drinking-in-the-dark) and in a rat model of alcohol dependence (vapor exposure).

The Mineralocorticoid Receptor: An Emerging Pharmacotherapeutic Target for Alcohol Use Disorder?

Despite the high prevalence and negative consequences associated with alcohol use disorder (AUD), currently available pharmacotherapies are limited in number and efficacy. Several neuroendocrine pathways have been identified and are under investigation as potential pharmacotherapeutic targets for AUD. Here, we present the promise of the mineralocorticoid receptor (MR) as a novel target and discuss associations between the aldosterone/MR system and AUD, the effects of MR antagonism on alcohol consumption, and the underlying neurobiology of these effects.

Crashing from cadaver to computer: Covid-driven crisis-mode pedagogy spawns active online substitute for teaching gross anatomy.

In early 2020, the Covid-19 crisis forced medical institutions worldwide to convert quickly to online platforms for content delivery. Although many components of medical education were adaptable to that format, anatomical dissection laboratory lost substantial content in that conversion, including features of active student participation, three-dimensional spatial relationships of structures, and the perception of texture, variation, and scale. The present study aimed to develop and assess online anatomy laboratory sessions that sought to preserve benefits of the dissection experience for first-year medical students.

COVID-19 Era Social Isolation among Older Adults.

Risk of COVID-19 exposure and more severe illness are serious concerns for older adults. Social distancing has worsened existing social isolation, with severe impacts on connectedness among seniors. The pandemic is threatening to cause an extended health crisis, with impacts including serious health consequences.

CRISPR/Cas9-Induced and Mutations Stacked With Confer High Oleic Acid Seed Oil in Pennycress ( L.).

Pennycress ( L.) is being domesticated as an oilseed cash cover crop to be grown in the off-season throughout temperate regions of the world. With its diploid genome and ease of directed mutagenesis using molecular approaches, pennycress seed oil composition can be rapidly tailored for a plethora of food, feed, oleochemical and fuel uses.

Drug addiction co-morbidity with alcohol: Neurobiological insights.

Addiction is a chronic disorder that consists of a three-stage cycle of binge/intoxication, withdrawal/negative affect, and preoccupation/anticipation. These stages involve, respectively, neuroadaptations in brain circuits involved in incentive salience and habit formation, stress surfeit and reward deficit, and executive function. Much research on addiction focuses on the neurobiology underlying single drug use.

Glucocorticoid receptor modulators decrease alcohol self-administration in male rats.

Alcohol use disorder (AUD) is associated with the dysregulation of brain stress and reward systems, including glucocorticoid receptors (GRs). The mixed glucocorticoid/progesterone receptor antagonist mifepristone and selective GR antagonist CORT113176 have been shown to selectively reduce alcohol consumption in alcohol-dependent rats. Mifepristone has also been shown to decrease alcohol consumption and craving for alcohol in humans with AUD.

Tolerance to alcohol: A critical yet understudied factor in alcohol addiction.

Alcohol tolerance refers to a lower effect of alcohol with repeated exposure. Although alcohol tolerance has been historically included in diagnostic manuals as one of the key criteria for a diagnosis of alcohol use disorder (AUD), understanding its neurobiological mechanisms has been neglected in preclinical studies. In this mini-review, we provide a theoretical framework for alcohol tolerance.

Implementation of a Telemental Health Training Program Across a Mental Health Department.

Telemental health (TMH) has increased substantially. However, health care systems have found it challenging to implement TMH ubiquitously. A quality improvement project guided by implementation science methodology was used to design and implement a TMH training program.

Trajectories of Sexual Satisfaction and Frequency During and After Couple Therapy for Relationship Distress.

Using a sample of 134 distressed, different-sex couples, this study investigated the effects of Integrative Behavioral Couple Therapy and Traditional Behavioral Couple Therapy on sexual dissatisfaction and sexual frequency both during treatment and in the five years following treatment. Therapy effects depended on treatment type, gender, and whether sexual distress was identified as a presenting problem; while couple therapy may initially improve some aspects of the sexual relationship, impacts tend to fade over follow-up. Couple therapy may benefit from incorporating a greater emphasis on sex and inclusion of techniques from sex therapy.

Impaired hypothalamic feedback dysregulates brain glucocorticoid signaling in genetically-selected Marchigian Sardinian alcohol-preferring rats.

Genetically-selected Marchigian Sardinian alcohol-preferring (msP) rats display comorbid symptoms of increased alcohol preference and elevated anxiety-like behavior. Heightened stress sensitivity in msPs is influenced by genetic polymorphisms of the corticotropin-releasing factor receptor in the central nucleus of the amygdala (CeA), as well as reduced influence of anti-stress mechanisms that normally constrain the stress response. Given this propensity for stress dysregulation, in this study, we expand on the possibility that msPs may display differences in neuroendocrine processes that normally terminate the stress response.

Telemental health training in the Veterans Administration Puget Sound Health Care System.

As a pioneer of training in the field of psychology, the Veterans Affairs (VA) HealthCare System serves as a leader in the training in and provision of Telemental Health (TMH) services in the United States. To meet goals toward continued expansion of these services, the VA TMH training program includes both web-based didactic courses and a skills competency test at a basic level with supervision and consultation in TMH for more advanced training and is available to staff psychologists and psychologist trainees. Despite these efforts, barriers for training in and implementation of TMH occur at the provider, system, and patient level.

Cadaver Rounds: A Comprehensive Exercise That Integrates Clinical Context Into Medical Gross Anatomy.

Problem: The purpose of medical schools is to train students to care for patients; however, the temporal and conceptual gap between course work and patient care may induce students to undervalue preclinical course work, thereby decreasing learning and retention. Bringing clinical context into preclinical courses reduces this problem, and many preclinical programs incorporate "cameo" appearances of clinical material. In contrast, the authors describe a comprehensive program at Virginia Commonwealth University School of Medicine that uses the cadaver as the students' first patient to embed clinical context within preclinical anatomy.

A Novel Role for the Endocannabinoid System in Ameliorating Motivation for Alcohol Drinking and Negative Behavioral Affect after Traumatic Brain Injury in Rats.

Traumatic brain injury (TBI) is associated with psychiatric dysfunction-including pain, cognitive impairment, anxiety, and increased alcohol use. We previously demonstrated that inhibiting endocannabinoid degradation post-TBI with JZL184 attenuates neuroinflammation and neuronal hyperexcitability at the site of injury and improves neurobehavioral recovery. This study aimed to determine the effect of JZL184 on post-TBI behavioral changes related to psychiatric dysfunction and post-TBI neuroadaptations in brain regions associated with these behaviors.

Asfotase alfa for infants and young children with hypophosphatasia: 7 year outcomes of a single-arm, open-label, phase 2 extension trial.

Background: Our previous phase 2, open-label study of 11 infants and young children with life-threatening perinatal or infantile hypophosphatasia showed 1 year safety and efficacy of asfotase alfa, an enzyme replacement therapy. We aimed to report the long-term outcomes over approximately 7 years of treatment.

Methods: We did a prespecified, end of study, 7 year follow-up of our single-arm, open-label, phase 2 trial in which children aged 3 years or younger with life-threatening perinatal or infantile hypophosphatasia were recruited from ten hospitals (six in the USA, two in the UK, one in Canada, and one in the United Arab Emirates).
