This reflects an optimism about the potential promise of psychedelics as therapeutics. As with all therapeutic interventions, research is needed not only into their benefits but also potential risks.

Spatiotemporal correlates of emotional conflict processing in typically developing adolescents using magnetoencephalography.

Brain networks involved in emotional conflict processing have been extensively studied using functional magnetic resonance imaging in adults. Yet, the temporal correlates of these brain activations are still largely unknown, particularly in a key phase of emotional development, adolescence. Here, we elucidate the spatiotemporal profile of emotional conflict processing in 24 typically developing adolescents (10-18 years; 22 Caucasian) during an emotional face-word Stroop task.

Advancing ketamine in the treatment hierarchy for refractory depression.

Evidence indicates that ketamine is highly effective, has a lower side effect profile and is better tolerated compared to many augmentation strategies for refractory depression. This, combined with data on psychiatric treatment outcome mediators, suggests that earlier intervention with ketamine could improve outcomes for patients suffering from refractory depression.

Talking to Your Patients About Psychedelics: Using an Informed Approach and Understanding Indications, Risks, and Benefits.

The Psychiatric Consultation Service at Massachusetts General Hospital sees medical and surgical inpatients with comorbid psychiatric symptoms and conditions. During their twice-weekly rounds, Dr Stern and other members of the Consultation Service discuss diagnosis and management of hospitalized patients with complex medical or surgical problems who also demonstrate psychiatric symptoms or conditions. These discussions have given rise to rounds reports that will prove useful for clinicians practicing at the interface of medicine and psychiatry.

A pathogen effector co-opts a host RabGAP protein to remodel pathogen interface and subvert defense-related secretion.

Pathogens have evolved sophisticated mechanisms to manipulate host cell membrane dynamics, a crucial adaptation to survive in hostile environments shaped by innate immune responses. Plant-derived membrane interfaces, engulfing invasive hyphal projections of fungal and oomycete pathogens, are prominent junctures dictating infection outcomes. Understanding how pathogens transform these host-pathogen interfaces to their advantage remains a key biological question.

Identification of Potent, Broad-Spectrum Coronavirus Main Protease Inhibitors for Pandemic Preparedness.

The COVID-19 pandemic highlights the ongoing risk of zoonotic transmission of coronaviruses to global health. To prepare for future pandemics, it is essential to develop effective antivirals targeting a broad range of coronaviruses. Targeting the essential and clinically validated coronavirus main protease (M), we constructed a structurally diverse M panel by clustering all known coronavirus sequences by M active site sequence similarity.

Ketamine for refractory depression: Save the best for last?

Ketamine has recently been shown to be non-inferior to electroconvulsive therapy (ECT), one of psychiatry's most effective treatments for depression. Given the novelty of ketamine as well as its interventional nature, ketamine is currently viewed as an alternative to ECT and as such, considered a third-line agent for treatment-refractory depression. However, available data suggest that ketamine carries a low side-effect burden and is better tolerated than many second-line augmentation strategies for depression.

A high throughput cell stretch device for investigating mechanobiology .

Mechanobiology is a rapidly advancing field, with growing evidence that mechanical signaling plays key roles in health and disease. To accelerate mechanobiology-based drug discovery, novel systems are needed that enable mechanical perturbation of cells in a format amenable to high throughput screening. Here, both a mechanical stretch device and 192-well silicone flexible linear stretch plate were designed and fabricated to meet high throughput technology needs for cell stretch-based applications.

Characterizing the accuracy of robotic bronchoscopy in localization & targeting of small pulmonary lesions.

Purpose: Considering the recent implementation of lung cancer screening guidelines, it is crucial that small pulmonary nodules are accurately diagnosed. There is a significant need for quick, precise, and minimally invasive biopsy methods, especially for patients with small lung lesions in the outer periphery. Robotic bronchoscopy (RB) has recently emerged as a novel solution.

Spatiotemporal responses to emotional conflict and its psychiatric correlates in adolescents with epilepsy using magnetoencephalography.

People with epilepsy often suffer from comorbid psychiatric disorders, which negatively affects their quality of life. Emotion regulation is an important cognitive process that is impaired in individuals with psychiatric disorders, such as depression. Adults with epilepsy also show difficulties in emotion regulation, particularly during later-stage, higher-order cognitive processing.

Enhancing the Small-Scale Screenable Biological Space beyond Known Chemogenomics Libraries with Gray Chemical Matter─Compounds with Novel Mechanisms from High-Throughput Screening Profiles.

Phenotypic assays have become an established approach to drug discovery. Greater disease relevance is often achieved through cellular models with increased complexity and more detailed readouts, such as gene expression or advanced imaging. However, the intricate nature and cost of these assays impose limitations on their screening capacity, often restricting screens to well-characterized small compound sets such as chemogenomics libraries.

Drug target prediction through deep learning functional representation of gene signatures.

Many machine learning applications in bioinformatics currently rely on matching gene identities when analyzing input gene signatures and fail to take advantage of preexisting knowledge about gene functions. To further enable comparative analysis of OMICS datasets, including target deconvolution and mechanism of action studies, we develop an approach that represents gene signatures projected onto their biological functions, instead of their identities, similar to how the word2vec technique works in natural language processing. We develop the Functional Representation of Gene Signatures (FRoGS) approach by training a deep learning model and demonstrate that its application to the Broad Institute's L1000 datasets results in more effective compound-target predictions than models based on gene identities alone.

Border Control: Manipulation of the Host-Pathogen Interface by Perihaustorial Oomycete Effectors.

Filamentous plant pathogens, including fungi and oomycetes, cause some of the most devastating plant diseases. These organisms serve as ideal models for understanding the intricate molecular interplay between plants and the invading pathogens. Filamentous pathogens secrete effector proteins via haustoria, specialized structures for infection and nutrient uptake, to suppress the plant immune response and to reprogram plant metabolism.

Arthrocentesis approaches to the phalangeal joints of the one humped camel (Camelus dromedarius).

Irrespective of the exceptional adaptation of dromedaries to harsh environmental conditions, they remain highly susceptible to joint lameness resulting from a range of diverse factors and conditions. The joints most often affected by traumatic osteoarthritis in dromedaries are the metacarpophalangeal and metatarsophalangeal joints. A comprehensive understanding of joint anatomy and topography of the dromedary is required to perform arthrocentesis correctly on affected joints.

A Model for Empowering Rural Solutions for Cervical Cancer Prevention (He Tapu Te Whare Tangata): Protocol for a Cluster Randomized Crossover Trial.

Background: Māori are the Indigenous people of Aotearoa (New Zealand). Despite global acceptance that cervical cancer is almost entirely preventable through vaccination and screening, wāhine Māori (Māori women) are more likely to have cervical cancer and 2.5 times more likely to die from it than non-Māori women.

Unraveling Lifelong Brain Morphometric Dynamics: A Protocol for Systematic Review and Meta-Analysis in Healthy Neurodevelopment and Ageing.

A high incidence and prevalence of neurodegenerative diseases and neurodevelopmental disorders justify the necessity of well-defined criteria for diagnosing these pathologies from brain imaging findings. No easy-to-apply quantitative markers of abnormal brain development and ageing are available. We aim to find the characteristic features of non-pathological development and degeneration in distinct brain structures and to work out a precise descriptive model of brain morphometry in age groups.
