'The Stegosaurus Appearance' on ultrasound to assist in identifying the correct spinal level for primary lumbar spinal surgery.

Lumbar spinal surgery relies on palpation of anatomical landmarks and X-ray imaging confirmation to identify the correct spinal level, therefore exposing patients and staff to radiation, and increasing intraoperative time and cost. Ultrasound (US) assistance is being used to visualise spinal anatomy by many specialities, such as neurology and anaesthetics, and can be used intraoperatively in selected spinal surgery cases. However, its potential use to check spinal levels prior to surgery remains understudied.

The inductive effect does not explain electron density in haloacetates: are our textbooks wrong?

The inductive effect is a central concept in chemistry and is often exemplified by the p values of acetic acid derivatives. The reduction in p is canonically attributed to the reduction in the electron density of the carboxylate group through the inductive effect. However, wave functional theory calculations presented herein reveal that the charge density of the carboxylate group is not explained by the inductive effect.

Molecular basis of human angiotensin-1 converting enzyme inhibition by a series of diprolyl-derived compounds.

Angiotensin-1-converting enzyme (ACE) is a zinc-dependent carboxypeptidase of therapeutic interest for the treatment of hypertension, inflammation and fibrosis. It consists of two homologous N and C catalytic domains, nACE and cACE, respectively. Unfortunately, the current clinically available ACE inhibitors produce undesirable side effects due to the nonselective inhibition of these domains.

The Lipliner Sign: Potential Cause of a False Positive Focused Assessment with Sonography in Trauma (FAST) Examination.

Background: The focused assessment with sonography in trauma (FAST) examination plays an essential role in diagnosing hemoperitoneum in trauma patients to guide prompt operative management. The FAST examination is highly specific for hemoperitoneum in trauma patients, and has been adopted in nontrauma patients to identify intraperitoneal fluid as a cause of abdominal pain or distension. However, causes of false positive FAST examinations have been described and require prompt recognition to avoid diagnostic uncertainty and inappropriate procedures.

"This Time It Was Different:" Creating a Multidisciplinary, Trauma-Informed, Victim-Centered Approach to Sexual Assault Cold Case Investigations and Prosecutions.

Police and prosecutors recommend that sexual assault survivors have a medical forensic exam and the collection of a sexual assault kit (SAK; also known as a "rape kit") to preserve biological evidence (e.g., semen, blood, saliva, hair) if they want to pursue criminal prosecution.

The Effect of Electrolyte Properties on Ionic Transport through Solid-State Nanopores: Experiment and Simulation.

Nanopore membranes enable versatile technologies that are employed in many different applications, ranging from clean energy generation to filtration and sensing. Improving the performance can be achieved by conducting numerical simulations of the system, for example, by studying how the nanopore geometry or surface properties change the ionic transport behavior or fluid dynamics of the system. A widely employed tool for numerical simulations is finite element analysis (FEA) using software, such as COMSOL Multiphysics.

Functional implications of unusual NOS and SONOS covalent linkages found in proteins.

The tertiary and quaternary structures of many proteins are stabilized by strong covalent forces, of which disulfide bonds are the most well known. A new type of intramolecular and intermolecular covalent bond has been recently reported, consisting of the Lys and Cys side-chains linked by an oxygen atom (NOS). These post-translational modifications are widely distributed amongst proteins, and are formed under oxidative conditions.

Purpose: Melanoma brain metastases (BMs) are associated with poor survival. Combination immune checkpoint inhibitors (ICIs) with anti-PD1 and anti-CTLA-4 are the international standard-of-care treatment. Most landmark clinical trials excluded real-world patients with symptomatic disease, poor performance status (PS), and steroid use.

Advances in the structural basis for angiotensin-1 converting enzyme (ACE) inhibitors.

Human somatic angiotensin-converting enzyme (ACE) is a key zinc metallopeptidase that plays a pivotal role in the renin-angiotensin-aldosterone system (RAAS) by regulating blood pressure and electrolyte balance. Inhibition of ACE is a cornerstone in the management of hypertension, cardiovascular diseases, and renal disorders. Recent advances in structural biology techniques have provided invaluable insights into the molecular mechanisms underlying ACE inhibition, facilitating the design and development of more effective therapeutic agents.

SCA44- and SCAR13-associated GRM1 mutations affect metabotropic glutamate receptor 1 function through distinct mechanisms.

Background And Purpose: Metabotropic glutamate receptor 1 (mGlu) is a promising therapeutic target for neurodegenerative CNS disorders including spinocerebellar ataxias (SCAs). Clinical reports have identified naturally-occurring mGlu mutations in rare SCA subtypes and linked symptoms to mGlu mutations. However, how mutations alter mGlu function remains unknown, as does amenability of receptor function to pharmacological rescue.

A first-principles alternative to empirical solvent parameters.

The use of solvents is ubiquitous in chemistry. Empirical parameters, such as the Kamlet-Taft parameters and Gutmann donor/acceptor numbers, have long been used to predict and quantify the effects solvents have on chemical phenomena. Collectively however, such parameters are unsatisfactory, since each describes ultimately the same non-covalent solute-solvent and solute-solute interactions in completely disparate ways.

Trace amine associated receptor 1: predicted effects of single nucleotide variants on structure-function in geographically diverse populations.

Trace Amine Associated Receptor 1 (TAAR1) is a novel pharmaceutical target under investigation for the treatment of several neuropsychiatric conditions. TAAR1 single nucleotide variants (SNV) have been found in patients with schizophrenia and metabolic disorders. However, the frequency of variants in geographically diverse populations and the functional effects of such variants are unknown.

Development of Putative Bivalent Dicovalent Ligands for the Adenosine A1 Receptor.

Accumulating evidence suggests that G protein-coupled receptors (GPCRs) can exist and function in homodimer and heterodimer forms. The adenosine A1 receptor (AR) has been shown to form both homodimers and heterodimers, but there is a lack of chemical tools to study these dimeric receptor populations. This work describes the synthesis and pharmacological evaluation of a novel class of bivalent GPCR chemical tools, where each ligand moiety of the bivalent compound contains a sulfonyl fluoride covalent warhead designed to be capable of simultaneously reacting with each AR of an AR homodimer.

Climate change and its impact on asthma.

Earth's climate is changing at an unprecedented pace, primarily due to anthropogenic causes including greenhouse gas emissions. Evidence shows a strong link between climate change and its effects on asthma. Healthcare professionals must be educated to advocate for and lead effective strategies to reduce the health risks of climate change.

Building a culture of support: The use of a social norms campaign to create a trauma-informed campus community.

In 2019, (Michigan State University) conducted a campus-wide climate survey on relationship violence and sexual misconduct (RVSM; the 'Know More' Survey), which revealed that many students, faculty, and staff did not know where to go for help or how to support survivors. The authors collaborated on the design and launch of the 'Support More' Campaign in 2021-2022, a trauma-informed social norms campaign created to educate the campus community on how to respond to disclosures of RVSM and how to access campus-based services. Undergraduate students, graduate/professional students, faculty, and staff ( = 10,993) completed another 'Know More' Survey in spring 2022.
