Project SummaryWe propose developing and validating a novel platform technology that combines the collection and chemical analysis of ultrafine particles using an in-situ multispectral technique. The sample, collected directly onto the analysis substrate, is analyzed via excitation-emission matrix (EEM) spectroscopy. This approach will be validated against laboratory combustion-generated aerosols, ...

Current treatments for asthma, while reducing exacerbations in a subset of patients by focusing on airway inflammation, do not eliminate them. Asthma exacerbations are a significant cause of morbidity and mortality in asthma as they can lead to airway injury, lung function decline and death. Exacerbations in more severe asthmatics are of particular concern, as health care costs and lost productivi ...

TITLE: Critical angle reflection imaging (CARi) for label-free quantification of molecular interactions SUMMARYMeasuring molecular interactions of proteins are critical for understanding protein functions and cellular processes, for discovery and validating biomarkers, and for developing and screening drugs. In particular, membrane proteins play key roles in many cellular functions and are the lar ...

To support DTRA’s agent-defeat efforts, we will refine a laser-based Optical Thermocouple (OTC) technology and build and deliver to DTRA a hardened OTC prototype. This OTC system will be capable of quantifying the localized temporal evolution of temperature inside a detonation environment. The OTC technology is based on two-color fluorescence thermometry to determine the temperature. After laser ...

Each year, millions of Americans receive evidence-based psychotherapies (EBPs) such as cognitive behavioral therapy (CBT) for the treatment of mental and behavioral health problems. Yet, at present, there is no scalable method for evaluating the quality of psychotherapy services. In research settings, human-based behavioral coding methods are used, but these are time consuming, costly, and rarely ...

Psychosis resulting from schizophrenia spectrum disorders and major mood disorders is one of the most disabling health concerns worldwide. Evidence-based psychotherapeutic interventions are recommended as standard of care by national psychosis treatment guidelines but are rarely accessible. Cognitive Behavioral Therapy for psychosis (CBTp) is the most well-researched psychotherapy for psychotic di ...

Cryo-electron microscopy (cryo-EM) is a powerful technique for imaging biological molecules in which samples are preserved in a frozen, hydrated state before imaging using an electron beam. The technique provides an alternative to X-ray crystallography for structural characterization of biological samples that are not crystallizable or do not crystallize in their native state. While cryo- EM sampl ...

ABSTRACT The development of radiation-induced lung injury (RILI) is a potentially fatal toxicity in cancer patients undergoing thoracic radiotherapy or in individuals exposed to ionizing radiation (IR) from a nuclear incident. The pathobiology of radiation pneumonitis and radiation-induced lung fibrosis (RILF) is complex but includes the deleterious effects of unchecked inflammation (reactive oxyg ...

ABSTRACT Vaccination represents the single most effective and cost‐effective medical intervention devised to date, saving lives and reducing morbidity and disability for billions of humans. Despite the early success of the oral polio vaccine, most vaccines are delivered parenterally, and as such are associated with pain, non‐compliance, biohazardous medical waste and the need for trained medic ...

Abstract Melanoma is the deadliest form of skin cancer, affecting an estimated 1.2 million Americans. The disease has a high propensity for dissemination, and metastatic melanoma has a dismal prognosis, with a median survival of only 5–8 months. Healthcare costs for melanoma in 2021 are projected to reach nearly $4 billion, with a rising incidence rate. Despite considerable efforts in recent yea ...
