The Involvement of Glutamate-mGluR5 Signaling in the Development of Vulvar Hypersensitivity.

Provoked vulvodynia (PV) is the leading cause of vulvar pain and dyspareunia. The etiology of PV is multifactorial and remains poorly understood. PV is associated with a history of repeated vulvar inflammation and is often accompanied by sensory neuromodulation as a result of activation of the metabotropic glutamate receptor 5 (mGluR5) in the sensory nerve terminals.

Inflammation-induced mast cell-derived nerve growth factor: a key player in chronic vulvar pain?

Provoked vulvodynia (PV) is characterized by localized chronic vulvar pain. It is associated with a history of recurrent inflammation, mast cell (MC) accumulation and neuronal sprouting in the vulva. However, the mechanism of how vulvar-inflammation promotes neuronal sprouting and gene-expression adaptation in the spinal cord, leading to hypersensitivity and painful sensations, is unknown.

Exploring venlafaxine effects on chronic vulvar pain: Changes in mood and pain regulation networks.

The etiology of idiopathic pain conditions, such as Provoked vulvodynia (PV), is multifactorial. The efficiency of venlafaxine, serotonin-noradrenaline reuptake inhibitor (SNRIs) in modulating vulvar pain led to the hypothesis that PV might involve central mechanisms. Here, we investigate whether vulvar pain is associated with gene-expression changes in mood, stress and pain systems, including amygdala (Amg), medial prefrontal cortex (mPFC), and periaqueductal gray matter (PAG).

HBO treatment enhances motor function and modulates pain development after sciatic nerve injury via protection the mitochondrial function.

Background: Peripheral nerve injury can cause neuroinflammation and neuromodulation that lead to mitochondrial dysfunction and neuronal apoptosis in the dorsal root ganglion (DRG) and spinal cord, contributing to neuropathic pain and motor dysfunction. Hyperbaric oxygen therapy (HBOT) has been suggested as a potential therapeutic tool for neuropathic pain and nerve injury. However, the specific cellular and molecular mechanism by which HBOT modulates the development of neuropathic pain and motor dysfunction through mitochondrial protection is still unclear.

Continuous Monitoring of Psychosocial Stress by Non-Invasive Volatilomics.

Stress is becoming increasingly commonplace in modern times, making it important to have accurate and effective detection methods. Currently, detection methods such as self-evaluation and clinical questionnaires are subjective and unsuitable for long-term monitoring. There have been significant studies into biomarkers such as HRV, cortisol, electrocardiography, and blood biomarkers, but the use of multiple electrodes for electrocardiography or blood tests is impractical for real-time stress monitoring.

A 10-year comparison of short versus long-term court-ordered psychiatric hospitalization: a follow-up study.

Background: The Israel Mental Health Act of 1991 stipulates a process for court-ordered involuntary psychiatric hospitalization. As in many Western countries, this process is initiated when an individual is deemed "not criminally responsible by reason of mental disorder (NCR-MD)" or "incompetent to stand trial (IST)." A patient thus hospitalized may be discharged by the district psychiatric committee (DPC).

Noninvasive Detection of Stress by Biochemical Profiles from the Skin.

Stress is a leading cause of several disease types, yet it is underdiagnosed as current diagnostic methods are mainly based on self-reporting and interviews that are highly subjective, inaccurate, and unsuitable for monitoring. Although some physiological measurements exist (., heart rate variability and cortisol), there are no reliable biological tests that quantify the amount of stress and monitor it in real time.

Blocking the ErbB pathway during adolescence affects the induction of anxiety-like behavior in young adult maternal immune activation offspring.

Epidemiological and experimental evidence demonstrates that maternal exposure to infection during gestation increases the offspring's risk of developing schizophrenia and other neurodevelopmental disorders. In addition, the NRG-ErbB4 signaling pathway is involved in brain development and neuropsychiatric disorders. Specifically, this pathway modulates the dopaminergic and GABAergic systems and is expressed in the early stages of prenatal development.

Long-term effects of prophylactic MgSO in maternal immune activation rodent model at adolescence and adulthood.

The effects of MgSO as an anti-inflammatory agent in pregnant women have been investigated in the last few years. Infections can cause an inflammatory reaction involving the placenta membranes and amniotic cavity. They may have short-term effects on the mother and her fetuses, like preterm birth, cerebral palsy, and developmental delay.

What we know about the role of corticosteroids in psychiatric disorders; evidence from animal and clinical studies.

Corticosteroids, often known as steroids, are anti-inflammatory medicine prescribed for various conditions. There is accumulating evidence of immune dysregulation in major psychiatric disorders. Significant changes in concentrations of inflammatory biomarkers (i.

An Ultra-Low Dose of ∆9-Tetrahydrocannabinol Alleviates Alzheimer's Disease-Related Cognitive Impairments and Modulates TrkB Receptor Expression in a 5XFAD Mouse Model.

Alzheimer's disease (AD) is the most common form of dementia, but there is still no available treatment. Δ9-tetrahydrocannabinol (THC) is emerging as a promising therapeutic agent. Using THC in conventional high doses may have deleterious effects.

Anxiolytic and antidepressants' effect of Crataegus pinnatifida (Shan Zha): biochemical mechanisms.

Depression and anxiety disorders are highly prevalent. Selective serotonin reuptake inhibitors (SSRIs) are the current first-line treatment for depression, but they have pronounced limitations. Traditional Chinese medicine can serve as a safe and effective alternative to conventional drugs, particularly since many herbal remedies have already been approved for human use as food additives, making the transition from bench to bedside more efficient.

Moderation of the transgenerational transference of antenatal stress-induced anxiety.

Maternal stress has debilitating implications for both mother and child, including increased risk for anxiety. The current COVID-19 pandemic escalates these phenomena, thus, urging the need to further explore and validate feasible therapeutic options. Unlike the protracted nature of clinical studies, animal models could offer swift evidence.

Patients' attitudes toward conventional and herbal treatments for depression and anxiety: A cross-sectional Israeli survey.

Background: As many patients view conventional antidepressants and anxiolytics negatively, it is not surprising that the willingness to apply these treatments is far from ideal, thus posing a critical barrier in promoting an effective and durable treatment.

Aim: The present study aimed to explore patients' attitudes toward conventional and herbal treatments for depression and anxiety, while considering cultural and demographic factors, to further elucidate the antecedes that putatively determine the treatment's outcome.

Methods: During June 2017, a cross-sectional survey was conducted using stratified sampling from a large-scale Israeli volunteer online panel.

Short-Term Effect of MgSO on the Expression of NRG-ErbB, Dopamine, GABA, and Glutamate Systems in the Fetal Rat Brain.

MgSO has been used for the past two decades as neuroprotective treatment in a variety of preterm conditions. Despite the putative advantages of MgSO as a neuroprotective agent in the preterm brain, the short- and long-term molecular function of MgSO as a neuroprotective agent has not been fully elucidated. Neuregulin (NRG1)-ErbB4 signaling plays a critical role in embryonic brain development, in the biology of dopaminergic, GABAergic, and glutamatergic systems.

Cerebral MAO Activity Is Not Altered by a Novel Herbal Antidepressant Treatment.

Inhibition of monoamine oxidase (MAO)-A/B can ameliorate depressive- and anxiety-related symptoms via increase of monoamine extracellular levels. However, such inhibition can also instigate hypertensive response following exposure to dietary tyramine (i.e.

Health benefits of a physical exercise program for inpatients with mental health; a pilot study.

The positive effect of exercise on human health and the relationship between physical activity, health, and wellbeing are well studied and extensively documented in the literature. However, considerably less attention is devoted to the impact of exercise on mental health and wellbeing for people experiencing a mental illness, in general, and in particular for inpatients in the mental health care system. Here, we determine the clinical feasibility and effects of short-term (up to three months) vs long-term (up to six months) group-based exercise program for inpatients with chronic mental health.

The influence of immune activation at early vs late gestation on fetal NRG1-ErbB4 expression and behavior in juvenile and adult mice offspring.

Maternal inflammation during pregnancy is associated with a higher incidence of mental disorders (e.g. schizophrenia and autism) in the offspring.

GABA Receptor Density Is Not Altered by a Novel Herbal Anxiolytic Treatment.

Anxiety disorders are highly prevalent and considered a major public health concern worldwide. Current anxiolytics are of limited efficacy and associated with various side effects. Our novel herbal treatment (NHT), composed of four constituents, was shown to reduce anxiety-like behavior while precluding a common side effect caused by current anxiolytics, i.

Association between mental disorders, cognitive disturbances and vitamin D serum level: Current state.

Background & Aims: Vitamin D deficiency has been identified as a global problem. Approximately 14% of the world population has inadequate vitamin D levels. This vitamin has been usually associated with bone disorders such as rickets, osteomalacia, and osteoporosis.

Shared Decision Making for Psychiatric Rehabilitation Services Before Discharge from Psychiatric Hospitals.

Shared decision making (SDM) is an effective health communication model designed to facilitate patient engagement in treatment decision making. In mental health, SDM has been applied and evaluated for medications decision making but less for its contribution to personal recovery and rehabilitation in psychiatric settings. The purpose of this pilot study was to assess the effect of SDM in choosing community psychiatric rehabilitation services before discharge from psychiatric hospitalization.

Abnormal neural hierarchy in processing of verbal information in patients with schizophrenia.

Previous research indicates abnormal comprehension of verbal information in patients with schizophrenia. Yet the neural mechanism underlying the breakdown of verbal information processing in schizophrenia is poorly understood. Imaging studies in healthy populations have shown a network of brain areas involved in hierarchical processing of verbal information over time.

Escitalopram and NHT normalized stress-induced anhedonia and molecular neuroadaptations in a mouse model of depression.

Anhedonia is defined as a diminished ability to obtain pleasure from otherwise positive stimuli. Anxiety and mood disorders have been previously associated with dysregulation of the reward system, with anhedonia as a core element of major depressive disorder (MDD). The aim of the present study was to investigate whether stress-induced anhedonia could be prevented by treatments with escitalopram or novel herbal treatment (NHT) in an animal model of depression.
