Forensic psychiatrists may be asked to opine on neurological evidence or neurological diseases outside the scope of their expertise. This article discusses the value of involving experts trained in behavioral neurology in such cases. First, we describe the field of behavioral neurology and neuropsychiatry, the subspecialty available to both neurologists and psychiatrists focused on the behavioral, cognitive, and neuropsychiatric manifestations of neurological diseases.

Neurologic evidence, including MRI, PET, and EEG, has been introduced in more than 2,800 criminal cases in the past decade, including 12% of all murder trials and 25% of death penalty trials, to argue whether neurologic diseases are present, contribute to criminal behavior, and ultimately whether the defendant is less criminally responsible, competent to stand trial, or should receive a reduced punishment for his or her crime. Unfortunately, neurologists are often not involved in these criminal cases despite being the medical specialty with the most relevant training and expertise to address these issues for the court. Reasons for the absence of neurologists in criminal cases include a lack of awareness from lawyers, judges, and other expert witnesses on the value of including neurologists in forensic evaluations, and the lack of experience, training, and willingness of neurologists to work as expert witnesses in criminal cases.

Increasing use of social media in forensic mental health evaluations will lead to new challenges that must be resolved by forensic practitioners and the legal system. One such dilemma is the discovery of information that would typically trigger a legal duty and professional ethics obligation for mental health professionals to breach doctor-patient confidentiality to promote public safety and prevent harm to vulnerable third parties. Although the law and professional organizations offer clear guidance for practitioners in the treatment role, there is currently no clarity from the law or instruction from professional organizations on what mental health professionals should do if they discover such information during a confidential forensic evaluation.

Neurological evidence is increasingly used in criminal cases to argue that a defendant is less responsible for their behaviour, is not competent to stand trial or should receive a reduced punishment for the crime. Unfortunately, neurologists are rarely involved in such cases despite having the expertise to help to inform these decisions in court. In this Perspective, we advocate for the development of 'forensic neurology', a subspecialty of neurology focused on using neurological clinical and scientific expertise to address legal questions for the criminal justice system.

Psychiatrists face complex ethics dilemmas in the COVID-19 pandemic era when assessing dangerousness in patients or forensic evaluees who threaten to purposely infect others or spread the virus. Understanding local public health and medical quarantine laws for their jurisdictions can help guide treating psychiatrists in how to handle some of these situations; however, challenges occur when what is ethically best conflicts with the action that will confer the greatest protection against legal liability. Additionally, the calculus of weighing competing ethics considerations changes based on how relevant it is to the duties of a particular role (e.

Intimate partner violence (IPV) has been a major public health threat long before COVID-19. However, the pandemic has removed protective measures from victims, while heightening risk factors associated with IPV. Emergency department providers are often the initial point of contact in the health care system for IPV victims; therefore, knowledge of current screening guidelines and best practices in assessment and management of IPV is essential.

Advances in psychiatric science and technology such as genetic testing hold great promise in enhancing care in treatment settings and improving truth-telling in forensic settings. Despite this promise, these emerging technological advances present considerable ethics dilemmas to forensic practitioners because of risks related to coercing evaluees to consent to testing, and not adequately informing people of forensic risks associated with these tests, as well as important prejudicial effects (e.g.

Agonism of the G protein-coupled bile acid receptor "Takeda G-protein receptor 5" (TGR5) aids in attenuating cholesterol accumulation due to atherosclerotic progression. Although mammalian bile compounds can activate TGR5, they are generally weak agonists, and more effective compounds need to be identified. In this study, two marine bile compounds (5β-scymnol and its sulfate) were compared with mammalian bile compounds deoxycholic acid (DCA) and ursodeoxycholic acid (UDCA) using an model of TGR5 agonism.

Endothelial barrier disruption is a hallmark of tissue injury, edema, and inflammation. Vascular endothelial cells express the G protein-coupled receptor (GPCR) protease acctivated receptor 1 (PAR1) and the ion channel transient receptor potential vanilloid 4 (TRPV4), and these signaling proteins are known to respond to inflammatory conditions and promote edema through remodeling of cell-cell junctions and modulation of endothelial barriers. It has previously been established that signaling initiated by the related protease activated receptor 2 (PAR2) is enhanced by TRPV4 in sensory neurons and that this functional interaction plays a critical role in the development of neurogenic inflammation and nociception.

Single domain antibodies that combine antigen specificity with high tissue penetration are an attractive alternative to conventional antibodies. However, rapid clearance from the bloodstream owing to their small size can be a limitation of therapeutic single domain antibodies. Here, we describe and evaluate the conjugation of a single domain i-body, AD-114, which targets CXCR4, to a panel of half-life extension technologies including a human serum albumin-binding peptide, linear and branched PEG, and PASylation (PA600).

Idiopathic pulmonary fibrosis (IPF) is a chronic fibrotic lung disease that is prevalent in individuals >50 years of age, with a median survival of 3-5 years and limited therapeutic options. The disease is characterized by collagen deposition and remodeling of the lung parenchyma in a process that is thought to be driven by collagen-expressing immune and structural cells. The G-protein coupled C-X-C chemokine receptor 4, CXCR4, is a candidate therapeutic target for IPF owing to its role in the recruitment of CXCR4 fibrocytes from the bone marrow to fibrotic lung tissue and its increased expression levels by structural cells in fibrotic lung tissue.

Protease-activated receptor 2 (PAR) is a proinflammatory G-protein coupled receptor (GPCR) that is activated by inflammatory proteases, and its activation initiates signaling pathways that modulate the nonselective cation channel transient receptor potential vanilloid-4 (TRPV4). PAR-dependent opening of TRPV4 has been attributed to kinase activation, but the identity of the responsible enzymes is unknown. Deciphering the signaling pathways involved in the PAR-dependent opening of TRPV4 may yield new targets for pain treatment.

Transient receptor potential ion channels (TRP) are a superfamily of non-selective ion channels which are opened in response to a diverse range of stimuli. The TRP vanilloid 4 (TRPV4) ion channel is opened in response to heat, mechanical stimuli, hypo-osmolarity and arachidonic acid metabolites. However, recently TRPV4 has been identified as an ion channel that is modulated by, and opened by intracellular signalling cascades from other receptors and signalling pathways.

Mechanosensitive ion channels are implicated in the biology of touch, pain, hearing and vascular reactivity; however, the identity of these ion channels and the molecular basis of their activation is poorly understood. We previously found that transient receptor potential vanilloid 4 (TRPV4) is a receptor operated ion channel that is sensitised and activated by mechanical stress. Here, we investigated the effects of mechanical stimulation on TRPV4 localisation and activation in native and recombinant TRPV4-expressing cells.
