Motivation for physical activity and the moderating effect of cancer diagnosis: A nationally representative cross-sectional study.

The aim of this study was to investigate associations between types of motivation for physical activity and self-reported weekly aerobic moderate-to-vigorous physical activity (MVPA) in the 2012 and 2014 waves of the nationally representative Health Information National Trends Survey 4 (n = 7307). We further explored differential associations between MVPA and types of motivation for physical activity by cancer survivor status. We found that those who were more motivated by "getting enjoyment from exerci...


Treatment challenges and outcomes for pediatric intracranial ependymoma at a single institution in Iran.

The scarcity of information on pediatric ependymoma in Iran motivated this study. Our main objectives were to determine outcomes, identify clinical management challenges at a nongovernment hospital in Iran, and devise guidelines for improving care.

Regulation of C. elegans L4 cuticle collagen genes by the heterochronic protein LIN-29.

The cuticle, the outer covering of the nematode C. elegans, is synthesized five times during the worm's life by the underlying hypodermis. Cuticle collagens, the major cuticle component, are encoded by a large family of col genes and, interestingly, many of these genes express predominantly at a single developmental stage. This temporal preference motivated us to investigate the mechanisms underlying col gene expression and here we focus on a subset of col genes expressed in the L4 stage. We identified mini...


How Do We Know when Single-Molecule Force Spectroscopy Really Tests Single Bonds?

Single-molecule force spectroscopy makes it possible to measure the mechanical strength of single noncovalent receptor-ligand-type bonds. A major challenge in this technique is to ensure that measurements reflect bonds between single biomolecules because the molecules cannot be directly observed. This perspective evaluates different methodologies for identifying and reducing the contribution of multiple molecule interactions to single-molecule measurements to help the reader design experiments or assess pub...

Can a single pulse transcranial magnetic stimulation targeted to the motor cortex interrupt pain processing?

The modulatory role of the primary motor cortex (M1), reflected by an inhibitory effect of M1-stimulation on clinical pain, motivated us to deepen our understanding of M1's role in pain modulation. We used Transcranial Magnetic Stimulation (TMS)-induced virtual lesion (VL) to interrupt with M1 activity during noxious heat pain. We hypothesized that TMS-VL will effect experimental pain ratings. Three VL protocols were applied consisting of single-pulse TMS to transiently interfere with right M1 activity: (1)...

Electrochemistry of Single Enzymes: Fluctuations of Catalase Activities.

Dynamic fluctuations of the catalytic ability of single catalase enzymes towards hydrogen peroxide decomposition are observed via the nano-impact technique. The electrochemical signals of single enzymes show that the catalytic ability of single enzymes can temporarily be much higher than expected from the classical, time-averaged Michaelis-Menten description. By combination of experimental data with a new theoretical model, we interpret the unusual enhancement of the single catalase signal and find that sin...

Hypocretin as a Hub for Arousal and Motivation.

The lateral hypothalamus is comprised of a heterogeneous mix of neurons that serve to integrate and regulate sleep, feeding, stress, energy balance, reward, and motivated behavior. Within these populations, the hypocretin/orexin neurons are among the most well studied. Here, we provide an overview on how these neurons act as a central hub integrating sensory and physiological information to tune arousal and motivated behavior accordingly. We give special attention to their role in sleep-wake states and cond...

Single use disposable digital flexible ureteroscopes: an ex-vivo assessment and cost analysis.

The single use flexible ureteroscope (fURS), the LithoVue is an important recent development. We aim to measure the capability of this instrument and to assess if there is a benefit to switching to single use instruments.

Negative stereotypes as motivated justifications for moral exclusion.

We investigated the connection between moral exclusion of outgroups and on the one hand, right-wing authoritarianism (RWA), and social dominance orientation (SDO) on the other. We assumed that both RWA and SDO would increase the tendency to place other groups out of the scope of justice. However, we also tested whether negative stereotypes about an outgroup's threatening and norm-violating misbehavior would serve as a justification for moral exclusion. These assumptions were tested in connection with Roma, ...

Close or far? Affect explains conflicting findings on motivated distance perception to rewards.

Research on motivated perception has yielded conflicting findings: Whereas Balcetis and Dunning (2010) showed that people approaching (vs. avoiding) rewarding objects (e.g. food) see them as closer, Krpan and Schnall (2014a) found the opposite. Furthermore, whereas Balcetis (2016) suggested that people who perceive rewarding objects as closer (vs. farther) should subsequently consume more, Krpan and Schnall (2017) showed that they actually ate less. We introduce affect as the missing link to explain these c...

Monostable multivibrators as novel artificial neurons.

Retriggerable and non-retriggerable monostable multivibrators are simple timers with a single characteristic, their period. Motivated by the fact that monostable multivibrators are implementable in large quantities as counters in digital programmable hardware, we set out to investigate their applicability as building blocks of artificial neural networks. We derive the nonlinear input-output firing rate relations for single multivibrator neurons as well as the equilibrium firing rate of large recurrent netwo...

Probing Single Pt Atoms in Complex Intermetallic AlFe.

The atomic structure of a 0.2 atom % Pt-doped complex metallic alloy, monoclinic AlFe, was investigated using a single crystal prepared by the Czochralski method. High-angle annular dark-field scanning transmission electron microscopy showed that the Pt atoms were dispersed as single atoms and substituted at Fe sites in AlFe. Single-crystal X-ray structural analysis revealed that the Pt atoms preferentially substitute at Fe(1). Unlike those that have been reported, Pt single atoms in the surface layers show...

Mapping the Mouse Cell Atlas by Microwell-Seq.

Single-cell RNA sequencing (scRNA-seq) technologies are poised to reshape the current cell-type classification system. However, a transcriptome-based single-cell atlas has not been achieved for complex mammalian systems. Here, we developed Microwell-seq, a high-throughput and low-cost scRNA-seq platform using simple, inexpensive devices. Using Microwell-seq, we analyzed more than 400,000 single cells covering all of the major mouse organs and constructed a basic scheme for a mouse cell atlas (MCA). We revea...

Resting beta activation and trait motivation: Neurophysiological markers of motivated motor-action preparation.

Based on Reinforcement Sensitivity Theory (Gray and McNaughton 2000), human behavior is influenced by systems of approach motivation, avoidance motivation, and a third regulatory system presiding over the other two. These systems mediate action and are likely related to neurophysiological markers of motor-action preparation. Previous research has found that lower levels of beta activity over the motor cortex are associated with greater motor-action preparation. The current study sought to test whether trait...

Measuring the Single-Photon Temporal-Spectral Wave Function.

Temporal-spectral modes of light provide a fundamental window into the nature of quantum systems and offer a robust means for information encoding. Methods to precisely characterize the temporal-spectral state of light at the single-photon level thus play a central role in understanding single-photon sources and their applications in emerging optical quantum technologies. Here we demonstrate an optical reference-free method, which melds techniques from ultrafast metrology and single-photon spectral detectio...

Current progress in single sperm cryopreservation.

Sperm cryopreservation has been widely used in assisted reproduction, but conventional techniques are not suitable for the cryopreservation of small numbers of sperm. The application of the single sperm cryopreservation technique has significantly improved the clinical treatment of cryptozoospermia and non-obstructive azoospermia. Ever since Cohen et al first developed the method of single sperm cryopreservation in 1997, constant efforts have been made to develop the carriers for this technique. In this rev...

Exponential scaling of single-cell RNA-seq in the past decade.

Measurement of the transcriptomes of single cells has been feasible for only a few years, but it has become an extremely popular assay. While many types of analysis can be carried out and various questions can be answered by single-cell RNA-seq, a central focus is the ability to survey the diversity of cell types in a sample. Unbiased and reproducible cataloging of gene expression patterns in distinct cell types requires large numbers of cells. Technological developments and protocol improvements have fuele...

Simultaneous Discrimination of Single-Base Mismatch and Full Match Using a Label-Free Single-Molecule Strategy.

Identification of single-base mismatches has found wide applications in disease diagnosis, pharmacogenetics and population genetics. However, there is still a great challenge in the simultaneous discrimination of single-base mismatch and full match. Combined with a nanopore electrochemical sensor, a shared-stem structure of molecular beacon (MB) was designed that did not need the labeling, but achieved an enhanced signal-to-background ratio (SBR) of ~10E4, high thermodynamic stability to bind with target se...

Demonstration of Single-Barium-Ion Sensitivity for Neutrinoless Double-Beta Decay Using Single-Molecule Fluorescence Imaging.

A new method to tag the barium daughter in the double-beta decay of ^{136}Xe is reported. Using the technique of single molecule fluorescent imaging (SMFI), individual barium dication (Ba^{++}) resolution at a transparent scanning surface is demonstrated. A single-step photobleach confirms the single ion interpretation. Individual ions are localized with superresolution (∼2  nm), and detected with a statistical significance of 12.9σ over backgrounds. This lays the foundation for a new and potentially...

Construction of Synthetic Antibody Libraries.

Libraries of antibody fragments displayed on filamentous phages are now a widely used approach to isolate antibodies against virtually any target. We describe a simple protocol to make large and diverse libraries based on a single or a limited number of frameworks. The approach is flexible enough to be used with any antibody format, either single-chain (scFv, VHH) or multi-chain (Fv, Fab, (Fab')2), and to target in a single step the six complementarity-determining regions-or any other part-of the antibody m...

Near-K-Edge Double and Triple Detachment of the F^{-} Negative Ion: Observation of Direct Two-Electron Ejection by a Single Photon.

Double and triple detachment of the F^{-}(1s^{2}2s^{2}2p^{6}) negative ion by a single photon have been investigated in the photon energy range 660 to 1000 eV. The experimental data provide unambiguous evidence for the dominant role of direct photodouble detachment with a subsequent single-Auger process in the reaction channel leading to F^{2+} product ions. Absolute cross sections were determined for the direct removal of a (1s+2p) pair of electrons from F^{-} by the absorption of a single photon.

Isoform-level gene expression patterns in single-cell RNA-sequencing data.

RNA sequencing of single cells enables characterization of transcriptional heterogeneity in seemingly homogeneous cell populations. Single-cell sequencing has been applied in a wide range of researches fields. However, few studies have focus on characterization of isoform-level expression patterns at the single-cell level. In this study we propose and apply a novel method, ISOform-Patterns (ISOP), based on mixture modeling, to characterize the expression patterns of isoform pairs from the same gene in singl...

Studying X chromosome inactivation in the single-cell genomic era.

Single-cell genomics is set to revolutionise our understanding of how epigenetic silencing works; by studying specific epigenetic marks or chromatin conformations in single cells, it is possible to ask whether they cause transcriptional silencing or are instead a consequence of the silent state. Here, we review what single-cell genomics has revealed about X chromosome inactivation, perhaps the best characterised mammalian epigenetic process, highlighting the novel findings and important differences between ...

Two Mechanisms Determine Quantum Dot Blinking.

Many potential applications of quantum dots (QDs) can only be realized once the luminescence from single nanocrystals (NCs) is understood. These applications include the development of quantum logic devices, single photon sources, long-life LEDs, and single molecule biolabels. At the single nanocrystal level, random fluctuations in the QD photo-luminescence (PL) occur, a phenomenon termed blinking. There are two competing models to explain this blinking: Auger recombination and surface trap induced recombin...

Bio-inspired visual self-localization in real world scenarios using Slow Feature Analysis.

We present a biologically motivated model for visual self-localization which extracts a spatial representation of the environment directly from high dimensional image data by employing a single unsupervised learning rule. The resulting representation encodes the position of the camera as slowly varying features while being invariant to its orientation resembling place cells in a rodent's hippocampus. Using an omnidirectional mirror allows to manipulate the image statistics by adding simulated rotational mov...
