OBJECTIVE: The option of performing MVD under awake anesthesia protocol ("awake" MVD) was examined in this initial series to assess whether intraoperative pain evaluation can identify and mitigate insufficient decompression of the trigeminal nerve, improving surgical outcomes. Additionally, "awake" MVD could expand procedure indications for those with comorbidities that would prohibit general endotracheal anesthesia (GEA). METHODS: An IRB-approved prospective study of 10 consecutive adults who underwent MVD for TN was conducted...

Bioengineering of a functional cardiac tissue composed of primary cardiomyocytes has great potential for myocardial regeneration and in vitro tissue modeling. However, its applications remain limited because the cardiac tissue is a highly organized structure with unique physiologic, biomechanical, and electrical properties. In this study, we undertook a proof-of-concept study to develop a contractile cardiac tissue with cellular organization, uniformity, and scalability by using three-dimensional (3D) bioprinting strategy...

The 21st Congress for the International Society for Aerosols in Medicine included, for the first time, a session on Pulmonary Delivery of Therapeutic and Diagnostic Gases. The rationale for such a session within ISAM is that the pulmonary delivery of gaseous drugs in many cases targets the same therapeutic areas as aerosol drug delivery, and is in many scientific and technical aspects similar to aerosol drug delivery. This article serves as a report on the recent ISAM congress session providing a synopsis of each of the presentations...

Aging is a modern concept: human life expectancy has more than doubled in less than 150 years in Western countries. Longer lifespan, however, reveals age-related diseases, including cerebrovascular diseases. The vascular system is a prime target of aging: the "wear and tear" of large elastic arteries exposed to a life-long pulsatile pressure causes arterial stiffening by fragmentation of elastin fibers and replacement by stiffer collagen. This arterial stiffening increases in return the amplitude of the pulse pressure (PP), its wave penetrating deeper into the microcirculation of low resistance, high flow organs such as the brain...

The evolution of metal-organic frameworks (MOFs) has been one of the most exciting aspects of materials chemistry over the last 20 years. In this Account, we discuss the development during this period in our understanding of the factors that control the crystallization of MOFs from solution. Both classical porous MOFs and dense MOF phases are considered. This is an opportune time at which to examine this complex area because the experimental tools now available to interrogate crystallization processes have matured significantly in the last 5 years, particularly with the use of in situ synchrotron X-ray diffraction...

Despite a great interest of identification of protein-protein interactions (PPIs) in biological systems, only few attempts have been made for a large-scale PPI screen in planta. Unlike biochemical assays, bimolecular fluorescence complementation (BiFC) allows visualization of the transient and weak PPIs in vivo at the subcellular resolution. However, when the non-fluorescent fragments are highly expressed, the spontaneous and irreversible self-assembly of the split halves can easily generate false positives...

Federica M Marelli-Berg, Maryam Jangani
Dynamic reorganization of the cytoskeleton is essential for numerous cellular processes including leukocyte migration. This process presents a substantial bioenergetic challenge to migrating cells as actin polymerization is dependent on ATP hydrolysis. Hence, migrating cells must increase ATP production to meet the increased metabolic demands of cytoskeletal reorganization. Despite this long-standing evidence, the metabolic regulation of leukocyte motility and trafficking has only recently begun to be investigated...

Chronic pancreatitis has been considered over the past years as a single disease, alcohol-induced and different from acute pancreatitis, in terms of etiology and prognosis. Actually, the introduction of a new concept of chronic pancreatitis, now considered as a fibroinflammatory process caused by multiple factors (toxic-metabolic, genetic, immunologic, obstructive), allow to better understand the pathogenesis of this complex disease. Furthermore, the discover of peculiar forms of chronic pancreatitis (autoimmune, paraduodenal, associated to gene mutations), different in term of clinical aspects, findings at imaging, prognosis and therapy, radically changed the concept of the disease...

The interfacial microcracks in the resin matrix composites are difficult to be detected and repaired. However, the self-healing concept provides opportunities to fabricate composites with unusual properties. In the present study, photothermal conversion Ag-Cu2S nanoparticles were immobilized onto poly(p‑phenylene benzobisoxazole) (PBO) fibers via a polydopamine chemistry. Benefit from the photothermal effects of Ag-Cu2S, the obtained PBO fibers (Ag-Cu2S-PBO) efficiently converted the light energy into heat under a Xenon lamp irradiation...

The philosophy of One Health is growing in concept and clarity. The interdependence of human, animal, and environmental health is the basis for the concept of One Health. One Health is a comprehensive approach to ensure the health of people, animals, and the environment through collaborative efforts. Preharvest food safety issues align with the grand concept of One Health. Imagine any food production system, and immediately, parallel images from One Health emerge: for example, transmission of zoonotic diseases, antibiotic residues, or resistance genes in the environment; environmental and animal host reservoirs of disease; challenges with rearing animals and growing fresh produce on the same farm; application and transport of manure or diseased animals...

Chondroitin Sulfate (CS) is a drug which is available as pharmaceutical-grade and nutriceutical-grade products, with important variations in preparation, composition, purity and therapeutic effects. Previous studies using pharmaceutical-grade CS suggested that the compound improves pain and function and delays structural progression in knee osteoarthritis (OA), whereas discrepant results were observed when lower grade preparations were investigated. The recently published chondroitin versus celecoxib versus Placebo Trial (CONCEPT) assessed the symptomatic effect of pharmaceutical-grade CS 800 mg/day in symptomatic knee OA...

Assessment of protein structure and interaction is crucial for understanding protein structure/function relationships. Compared to high-resolution structural tools, including X-ray crystallography, nuclear magnetic resonance (NMR), and cryo-EM, and traditional low-resolution methods, such as circular dichroism, UV-vis, and florescence spectroscopy, mass spectrometry (MS)-based protein footprinting affords medium-to-high resolution (i.e., regional and residue-specific insights) by taking advantage of proteomics methods focused on the primary structure...

A novel, pure, synthetic material is presented that promotes the repair of full-thickness skin wounds. The active component is tropoelastin and leverages its ability to promote new blood vessel formation and its cell recruiting properties to accelerate wound repair. Key to the technology is the use of a novel heat-based, stabilized form of human tropoelastin which allows for tunable resorption. This implantable material contributes a tailored insert that can be shaped to the wound bed, where it hydrates to form a conformable protein hydrogel...
