Dendritic cells (DCs) belong to the first line of innate defense and come into early contact with invading pathogens, including the zoonotic bacterium Coxiella burnetii, the causative agent of Q fever. However, the pathogen-host cell interactions in C. burnetii-infected DCs, particularly the role of mechanisms of immune subversion beyond virulent phase I lipopolysaccharide (LPS), as well as the contribution of cellular self-defense strategies, are not understood.

Tunneling nanotubes (TNTs) are transient cellular connections that consist of dynamic membrane protrusions. They play an important role in cell-to-cell communication and mediate the intercellular exchanges of molecules and organelles. TNTs can form between different cell types and may contribute to the spread of pathogens by serving as cytoplasmic corridors.

We present a new and straightforward method by which standard cell culture plates can be sealed off from ambient air and be placed under controlled hypoxic cell culture conditions without costly or highly specialized materials. The method was established on a murine cell culture system using the dendritic cell line JAWS II but can be readily adapted to other cell cultures. The procedure was designed to be easy to implement in cell culture laboratories with standard incubators and requires only readily available materials, resources, and consumables, such as six-well plates, degassed culture medium, CoCl, a vacuum sealer, etc.

The Quidel Sofia severe acute respiratory syndrome (SARS) fluorescent immunoassay (FIA) test (SOFIA) is a rapid antigen immunoassay for the detection of SARS coronavirus 2 (SARS-CoV-2) proteins from nasal or nasopharyngeal swab specimens. The purpose of this study was to compare the results of the SOFIA test to those of the Hologic Aptima SARS-CoV-2 TMA test (APTIMA TMA), a high-throughput molecular diagnostic test that uses transcription-mediated amplification (TMA) for the detection of SARS-CoV-2 nucleic acid from upper respiratory tract specimens. Three hundred forty-seven symptomatic patients from an urgent care center in an area with a high prevalence of SARS-CoV-2 infections were tested in parallel using nasal swabs for the SOFIA test and nasopharyngeal swabs for the APTIMA TMA test.

Dendritic cells (DCs) and natural killer (NK) cells are critically involved in the early response against various bacterial microbes. Functional activation of infected DCs and NK cell-mediated gamma interferon (IFN-γ) secretion essentially contribute to the protective immunity against How DCs and NK cells cooperate during the antichlamydial response is not fully understood. Therefore, in the present study, we investigated the functional interplay between -infected DCs and NK cells.

Chaperone-assisted selective autophagy (CASA) initiated by the cochaperone Bcl2-associated athanogene 3 (BAG3) represents an important mechanism for the disposal of misfolded and damaged proteins in mammalian cells. Under mechanical stress, the cochaperone cooperates with the small heat shock protein HSPB8 and the cytoskeleton-associated protein SYNPO2 to degrade force-unfolded forms of the actin-crosslinking protein filamin. This is essential for muscle maintenance in flies, fish, mice and men.

Background And Purpose: Mind-body practices that blend physical movement or postures with a focus on the breath and a meditative state to achieve deep states of relaxation have recently been characterized as a category of exercise called meditative movement and include practices such as Yoga, Tai Chi, and Qigong. Critical components of such practices have not been adequately assessed in research, leaving the fidelity of interventions in question; however, there is currently no set of relevant instruments. This article describes the development and preliminary validation of two subscales of the meditative movement inventory (MMI).

Introduction: Meditative Movement (MM) is proposed as a new category of exercise defined by (a) some form of movement or body positioning, (b) a focus on breathing, and (c) a cleared or calm state of mind with a goal of (d) deep states of relaxation.

Review: Two forms of exercise meeting this definition, Qigong and Tai Chi, are reviewed to examine health benefits found in the research literature, recap elements that should be assessed in MM research, and suggest where aspects of MM intersect with, and are distinguished from, conventional forms of exercise.

Results: Relevant dimensions of the key elements of MM, such as frequency, duration, type of movement, degree of exertion, description of breathing, and achievement of relaxed state are recommended to be clearly described and measured to consistently define the category across studies and clarify how MM may affect health outcomes in similar, and perhaps different, ways than conventional exercise.

A quantitative framework was developed which estimates mercury methylation rates (MMR) in sediment cores based on measured sulfate reduction rates (SRR) and the community composition sulfate-reducing bacterial consortia. MMR and SRR as well as group-specific 16S rRNA concentrations (as quantified by probe signal) associated with sulfate-reducing bacteria (SRB) were measured in triplicate cores of saltmarsh sediments. Utilizing previously documented conversion factors in conjunction with field observations of sulfate reduction, MMR were calculated, and the results were compared to experimentally derived measurements of MMR.
