The interaction between tumor and immune system plays a crucial role in both cancer development treatment response. To facilitate comprehensive investigation of tumor-immune interactions, we have designed user-friendly web portal TISIDB, which integrated multiple types data resources oncoimmunology. First, manually curated 4176 records from 2530 publications, reported 988 genes related to anti-tumor immunity. Second, associated with the resistance or sensitivity cells T cell-mediated killing...

Objectives. To describe the characteristics and attitudes toward complementary alternative medicine (CAM) use among primary care patients with chronic pain disorders to determine if CAM is associated better control. Design. Cross-sectional survey. Subjects. Four hundred sixty-three suffering from chronic, nonmalignant receiving at 12 U.S. academic medical centers. Outcome Measure. Self-reported current usage by disorders. Results. The survey had an 81% response rate. Fifty-two percent...

When planning planetary rover missions it is useful to develop intuition and skills driving in, quite literally, alien environments before incurring the cost of reaching said locales. Simulators make possible operate in that have physical characteristics target locations without expense overhead extensive tests. To end, NASA Ames Open Robotics collaborated on a Lunar simulator based open source Gazebo simulation platform leveraging ROS (Robotic Operating System)components. The was integrated...

Micropollutants, which occur at low concentration in the environment, are ubiquitous, hazardous, and difficult to remove from water by using current methods. This work introduces hydrogel-based polymeric absorbents containing immobilized micelles for removal of hydrophobic micropollutants water. Acrylated surfactants synthesized self-assemble into with cores. The acrylate groups enable incorporation poly(ethylene glycol) diacrylate (PEGDA) hydrogels free radical polymerization. NMR...

Abstract Autism spectrum disorder (ASD) is a major neurodevelopmental affecting 1 in 36 children the United States. While neurons have been focus to understand ASD, an altered neuro-immune response brain may be closely associated with and interaction could play role disease progression. As resident immune cells of brain, microglia regulate development homeostasis via core functions including phagocytosis synapses. ASD has traditionally considered polygenic disorder, recent large-scale human...

Abstract This article surveyed attending physicians on their work hours, sleep schedule, daytime sleepiness, and the perceived relation of these factors to patient safety, quality care, personal well-being. Physicians answered demographic workload questions attitudinal regarding work-hour limitations; Epworth Sleepiness Scale (ESS) was used measure subjective an 18-item Impact Questionnaire also used. Of 180 participants, 41 (23%) manifested abnormal ESS scores (11 or greater). Private...

Abstract Persistent organic pollutants (POPs), including xenoestrogens and polyfluoroalkyl substances (PFAS), demand urgent global intervention. Fenton oxidation, catalyzed by iron ions, offers a cost‐effective means to degrade POPs. However, numerous challenges like acid dependency, catalyst loss, toxic waste generation hinder practical application. Efforts create long‐lasting heterogeneous catalysts, capable of simultaneously eliminating requirements, sustaining rapid kinetics, retaining...

Neuronal hyperexcitability is a hallmark of epilepsy. It has been recently shown in rodent models seizures that microglia, the brain's resident immune cells, can respond to and modulate neuronal excitability. However, how human microglia interact with neurons regulate mediated by an epilepsy-causing genetic mutation found patients unknown. The SCN2A gene responsible for encoding voltage-gated sodium channel Nav1.2, one leading contributors monogenic epilepsies. Previously, we demonstrated...
