Building Bridges to Advance Specialty Practice: Updates and Accomplishments by the American Academy of Emergency Nurse Practitioners.

Single cell transcriptomics in neuroscience: cell classification and beyond.

Biology has been facing a daunting problem since the cell was understood to be the building block of metazoans: how do we study multicellular systems, when a universal approach to characterize their building blocks and classify them does not exist? Metazoan diversity has not helped: there are many model and non-model organisms, developmental and adult stages, healthy and diseased states. Here, I review the application of single cell transcriptomics to cell classification in neuroscience and its corollaries:...


Numerical and experimental study on noise reduction of concrete LRT bridges.

Rolling noise and structure-borne noise radiating from the bridge are two major sources of noise in light rapid transit (LRT) bridges. To control the noise radiation from LRT bridges, an efficient numerical method for noise prediction is needed. In this study, a combined three-dimensional dynamic model and 2.5-dimensional acoustic model were used to investigate noise reduction in a rail and in a U-shaped girder bridge. The effects of three noise mitigation measures on noise control were then compared: insta...

Building Bridges between Gerontology and Elder Law.

Academics have long called for greater interaction between gerontologists and legal scholars. However, prior studies have suggested that disciplinary borders remain a barrier to such interaction, hampering gerontology's ability to function as a truly multi- or interdisciplinary field.

Mutual interaction of red blood cells assessed by optical tweezers and scanning electron microscopy imaging.

The adhesion of red blood cells (RBC) has been studied extensively in frame of cell-to-cell interaction induced by dextran macromolecules, whereas the data are lacking for native plasma solution. We apply optical tweezers to investigate the induced adhesion of RBC in plasma and in dextran solution. Two hypotheses, cross-bridges and depletion layer, are typically used to describe the mechanism of cell interaction; however, both mechanisms need to be confirmed experimentally. These interactions in fact are ve...

Dose analysis of photobiomodulation therapy on osteoblast, osteoclast, and osteocyte.

The objective of this study was to evaluate the effects of varying light doses on the viability and cellular activity of osteoblasts, osteocytes, and osteoclasts. A light application device was developed to apply 940-nm wavelength light from light-emitting diodes on three cultured cells, MC3T3-E1, MLO-A5, and RANKL-treated RAW264.7 cells. The doses (energy density) on cells were 0, 1, 5, and 7.5  J  /  cm2. The corresponding light power densities at the cell site were 0, 1.67, 8.33, and 12.5 ...

Gazing at Cell Wall Expansion under a Golden Light.

In plants, cell growth is constrained by a stiff cell wall, at least this is the way textbooks usually present it. Accordingly, many studies have focused on the elasticity and plasticity of the cell wall as prerequisites for expansion during growth. With their specific evolutionary history, cell wall composition, and environment, brown algae present a unique configuration offering a new perspective on the involvement of the cell wall, viewed as an inert material yet with intrinsic mechanical properties, in ...

Estimation of the bacteriochlorophyll c oligomerisation extent in Chloroflexus aurantiacus chlorosomes by very low-frequency vibrations of the pigment molecules: A new approach.

In green photosynthetic bacteria, the chlorosomal bacteriochlorophyll molecules are organized via self-assembly and do not require proteins to provide a scaffold for efficient light harvesting. Despite numerous investigations, a consensus regarding the spatial structure of chlorosomal antennae has not yet been reached. For the first time, we demonstrated by coherent femtosecond spectroscopy at cryogenic temperature that the very low-frequency (~10 cm) vibrations of bacteriochlorophyll c pigments in isolat...

Visible light controls cell adhesion on a photoswitchable biointerface.

Bioactive surfaces with specific interactions with cells have been greatly interested due to their potential applications in biosensors and tissue engineering. Herein, we fabricated a dopamine contained photoswitch molecule (compound 1) which could form self-assembled monolayer (SAM) on substrates. The SAM showed a good photoswitch ability and manifested excellent fatigue resistance, which displayed its potential application as a biologically friendly surface coating. Contact angle analysis and cell experim...

Transcriptome analysis of the cyanobacterium Synechocystis sp. PCC 6803 and mechanisms of photoinhibition tolerance under extreme high light conditions.

Photoinhibition, or cell damage caused by excessively intense light is a major issue for the industrial use of cyanobacteria. To investigate the mechanism of responses to extreme high light intensity, gene expression analysis was performed using the model cyanobacterium Synechocystis sp. PCC 6803 (PCC 6803) cultured under various light intensities. The culture profile data demonstrated that, in contrast to the slow cell growth observed under low light intensities (30 and 50 μmol m s), maximal cell growt...

Light or thermally-powered autonomous rolling of an elastomer rod.

Specially arranged external stimuli or carefully designed geometry are often essential for realizing continuous autonomous motion of active structures without self-carried power. As a consequence, it is usually very challenging to further integrate those structures as active building blocks into a system with complex form and multifunction. In this letter, we report an autonomous motion of a surprisingly simple setup: a cylindrical elastomer rod on a flat hot surface or under homogenous illumination of visi...

Blue light emitting diodes irradiation causes cell death in colorectal cancer by inducing ROS production and DNA damage.

The light emitting diodes (LEDs) irradiation has been demonstrated to be potential therapeutic strategies for several diseases. However, the blue LED effects remain largely unknown in colorectal cancer (CRC), which is a major cause of morbidity and mortality throughout the world. In this study, we determined the effects of blue LED irradiation, the maximal light emission at 470 nm in wavelength, in human CRC cell lines SW620 and HT29. The cells were irradiated with blue LED light for 0 J/cm, 72 J/cm, ...

Interactions Between the Perception of Light and Temperature.

Expanding the acceptable range of indoor temperatures allows to reduce building energy consumption and may be beneficial for health. Therefore, we explored whether light conditions can be used to influence thermal perception under various ambient temperatures. In two laboratory experiments we tested the effect of the correlated colour temperature of light (2700 K and 5800 K) and its intensity (5 lux and 1200 lux) on thermal perception. The light exposures were provided during cool, neutral and warm thermal ...

Prospectively Isolated Tetraspanin Neoblasts Are Adult Pluripotent Stem Cells Underlying Planaria Regeneration.

Proliferating cells known as neoblasts include pluripotent stem cells (PSCs) that sustain tissue homeostasis and regeneration of lost body parts in planarians. However, the lack of markers to prospectively identify and isolate these adult PSCs has significantly hampered their characterization. We used single-cell RNA sequencing (scRNA-seq) and single-cell transplantation to address this long-standing issue. Large-scale scRNA-seq of sorted neoblasts unveiled a novel subtype of neoblast (Nb2) characterized b...

The Misshapen kinase regulates the size and stability of the germline ring canals in the Drosophila egg chamber.

Intercellular bridges are conserved structures that allow neighboring cells to exchange cytoplasmic material; defects in intercellular bridges can lead to infertility in many organisms. Here, we use the Drosophila egg chamber to study the mechanisms that regulate intercellular bridges. Within the developing egg chamber, the germ cells (15 nurse cells and 1 oocyte) are connected to each other through intercellular bridges called ring canals, which expand over the course of oogenesis to support the transfer o...

The 10,000 Immunomes Project: Building a Resource for Human Immunology.

Opportunities for Lipid-Based Probes in the Field of Immunology.

Lipids perform a wide range of functions inside the cell, ranging from structural building block of membranes and energy storage to cell signaling. The mode of action of many signaling lipids has remained elusive due to their low abundance, high lipophilicity, and inherent instability. Various chemical biology approaches, such as photoaffinity or activity-based protein profiling methods, have been employed to shed light on the biological role of lipids and the lipid-protein interaction profile. In this revi...
