House Dust Mite Extract Forms a Der p 2 Corona on Multi-Walled Carbon Nanotubes: Implications for Allergic Airway Disease.

Multi-walled carbons nanotubes (MWCNTs) are used in materials for the construction, automotive, and aerospace industries. Workers and consumers are exposed to these materials via inhalation. Existing recommended exposure limits are based on MWCNT exposures that do not take into account more realistic co-exposures. Our goal was to understand how a common allergen, house dust mites, interacts with pristine MWCNTs and lung fluid proteins. We used gel electrophoresis, western blotting, and proteomics to characterize the composition of the allergen corona formed from house dust mite extract on the surface of MWCNTs. We found that the corona is dominated by der p 2, a protein associated with human allergic responses to house dust mites. Der p 2 remains adsorbed on the surface of the MWCNTs following subsequent exposures to lung fluid proteins. The high concentration of der p 2, localized on surface of MWCNTs, has important implications for house dust mite-induced allergies and asthma. This research provides a detailed characterization of the complex house dust mite-lung fluid protein coronas for future cellular and in vivo studies. These studies will help to address the molecular and biochemical mechanisms underlying the exacerbation of allergic lung disease by nanomaterials.

Wide-field calcium imaging reveals widespread changes in cortical functional connectivity following mild traumatic brain injury in the mouse.

>2.5 million individuals in the United States suffer mild traumatic brain injuries (mTBI) annually. Mild TBI is characterized by a brief period of altered consciousness, without objective findings of anatomic injury on clinical imaging or physical deficit on examination. Nevertheless, a subset of mTBI patients experience persistent subjective symptoms and repeated mTBI can lead to quantifiable neurological deficits, suggesting that each mTBI alters neurophysiology in a deleterious manner not detected using current clinical methods. To better understand these effects, we performed mesoscopic Ca2+ imaging in mice to evaluate how mTBI alters patterns of neuronal interactions across the dorsal cerebral cortex. Spatial Independent Component Analysis (sICA) and Localized semi-Nonnegative Matrix Factorization (LocaNMF) were used to quantify changes in cerebral functional connectivity (FC). Repetitive, mild, controlled cortical impacts induce temporary neuroinflammatory responses, characterized by increased density of microglia exhibiting de-ramified morphology. These temporary neuro-inflammatory changes were not associated with compromised cognitive performance in the Barnes maze or motor function as assessed by rotarod. However, long-term alterations in functional connectivity (FC) were observed. Widespread, bilateral changes in FC occurred immediately following impact and persisted for up to 7 weeks, the duration of the experiment. Network alterations include decreases in global efficiency, clustering coefficient, and nodal strength, thereby disrupting functional interactions and information flow throughout the dorsal cerebral cortex. A subnetwork analysis shows the largest disruptions in FC were concentrated near the impact site. Therefore, mTBI induces a transient neuroinflammation, without alterations in cognitive or motor behavior, and a reorganized cortical network evidenced by the widespread, chronic alterations in cortical FC.

New interaction modalities between the pharmaceutical industry and physicians.

Due to sanitary restrictions secondary to the COVID-19 pandemic, various interactions between the pharmaceutical industry and physicians have changed. One of them has been the method for promoting medicinal products through academic meetings around diseases of financial interest. A recent modality has been unilateral promotion by the pharmaceutical industry through academic events with the invitation of so-called "experts" for the promotion of a specific drug. These meetings are often biased not towards optimal care of a disease, but rather towards commercial promotion of a specific drug, which may or may not be the best option, without considering associated therapeutic alternatives. The Committee of Ethics and Transparency in the Physician-Industry Relationship, of the National Academy of Medicine, analyzes this new circumstance and proposes some considerations to the medical community.

Miniaturized head-mounted microscope for whole-cortex mesoscale imaging in freely behaving mice.

The advent of genetically encoded calcium indicators, along with surgical preparations such as thinned skulls or refractive-index-matched skulls, has enabled mesoscale cortical activity imaging in head-fixed mice. However, neural activity during unrestrained behavior substantially differs from neural activity in head-fixed animals. For whole-cortex imaging in freely behaving mice, we present the 'mini-mScope', a widefield, miniaturized, head-mounted fluorescence microscope that is compatible with transparent polymer skull preparations. With a field of view of 8 × 10 mm2 and weighing less than 4 g, the mini-mScope can image most of the mouse dorsal cortex with resolutions ranging from 39 to 56 µm. We used the mini-mScope to record mesoscale calcium activity across the dorsal cortex during sensory-evoked stimuli, open field behaviors, social interactions and transitions from wakefulness to sleep.

Assembly and operation of an open-source, computer numerical controlled (CNC) robot for performing cranial microsurgical procedures.

Cranial microsurgery is an essential procedure for accessing the brain through the skull that can be used to introduce neural probes that measure and manipulate neural activity. Neuroscientists have typically used tools such as high-speed drills adapted from dentistry to perform these procedures. As the number of technologies available for neuroscientists has increased, the corresponding cranial microsurgery procedures to deploy them have become more complex. Using a robotic tool that automatically performs these procedures could standardize cranial microsurgeries across neuroscience laboratories and democratize the more challenging procedures. We have recently engineered a robotic surgery platform that utilizes principles of computer numerical control (CNC) machining to perform a wide variety of automated cranial procedures. Here, we describe how to adapt, configure and use an inexpensive desktop CNC mill equipped with a custom-built surface profiler for performing CNC-guided microsurgery on mice. Detailed instructions are provided to utilize this 'Craniobot' for performing circular craniotomies for coverslip implantation, large craniotomies for implanting transparent polymer skulls for cortex-wide imaging access and skull thinning for intact skull imaging. The Craniobot can be set up in <2 weeks using parts that cost <$1,500, and we anticipate that the Craniobot could be easily adapted for use in other small animals.

Importancia de la investigación clínica independiente en la medicina: dificultades y recomendaciones.

Clinical research is the most important tool for the identification of diagnostic and therapeutic strategies that derive in higher efficacy and safety. Despite its significance, successful implementation of clinical research faces numerous difficulties, with one the most relevant being limited availability of resources for the performance of independent clinical trials. Generally, the pharmaceutical industry absorbs the costs associated with most clinical trials; however, this can generate dissociation between subjects of interest and health priorities when economic interest is the main driver of these protocols. In addition to the relevant role played by the pharmaceutical industry, it is important that government agencies favor adequate conditions, both in economic and regulatory aspects, for the implementation of independent clinical research that addresses subjects of medical and therapeutic interest, even if it does not generate corporate economic benefits.

La investigación clínica es la herramienta de mayor importancia para la identificación de estrategias diagnósticas y terapéuticas que deriven en mayor eficacia y seguridad. A pesar de su trascendencia, la implementación exitosa de la investigación clínica presenta numerosas dificultades; entre las más relevantes se encuentra la poca disponibilidad de recursos para realizar ensayos clínicos independientes. Por lo general, la industria farmacéutica absorbe los costos asociados con la mayoría de los ensayos clínicos, sin embargo, esto puede generar una disociación entre los temas de interés y las prioridades en salud, al existir interés económico como principal motivación de estos protocolos. Además del papel relevante de la industria farmacéutica, es importante que las instancias gubernamentales favorezcan las condiciones, tanto económicas como regulatorias, para la implementación de investigación clínica independiente, que aborde temas de interés médico y terapéutico, aunque no genere beneficios económicos empresariales.
