Housing and testing in mixed-sex rooms increases motivation and accuracy during operant testing in both male and female mice.

Operant behavior tasks are widely used in neuroscience research, but little is known about how variables such as housing and testing conditions affect rodent operant performance. We have previously observed differences in operant performance in male and female mice depending on whether mice were housed and tested in rooms containing only one sex versus rooms containing both sexes. Here, male and female mice in either single-sex or mixed sex housing rooms were trained on fixed ratio 1 (FR1) and progressive r...


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.

Search for Invisible Decays of a Dark Photon Produced in e^{+}e^{-} Collisions at BaBar.

We search for single-photon events in 53  fb^{-1} of e^{+}e^{-} collision data collected with the BABAR detector at the PEP-II B-Factory. We look for events with a single high-energy photon and a large missing momentum and energy, consistent with production of a spin-1 particle A^{'} through the process e^{+}e^{-}→γA^{'}; A^{'}→invisible. Such particles, referred to as "dark photons," are motivated by theories applying a U(1) gauge symmetry to dark matter. We find no evidence for such processes and...


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...

Single dose moxidectin versus ivermectin for Onchocerca volvulus infection in Ghana, Liberia, and the Democratic Republic of the Congo: a randomised, controlled, double-blind phase 3 trial.

The morbidity and socioeconomic effects of onchocerciasis, a parasitic disease that is primarily endemic in sub-Saharan Africa, have motivated large morbidity and transmission control programmes. Annual community-directed ivermectin treatment has substantially reduced prevalence. Elimination requires intensified efforts, including more efficacious treatments. We compared parasitological efficacy and safety of moxidectin and ivermectin.

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)...

Central and Divided Visual Field Presentation of Emotional Images to Measure Hemispheric Differences in Motivated Attention.

Two dominant theories on lateralized processing of emotional information exist in the literature. One theory posits that unpleasant emotions are processed by right frontal regions, while pleasant emotions are processed by left frontal regions. The other theory posits that the right hemisphere is more specialized for the processing of emotional information overall, particularly in posterior regions. Assessing the different roles of the cerebral hemispheres in processing emotional information can be difficult...

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...

Genome-wide segregation of single nucleotide and structural variants into single cancer cells.

Single-cell genome sequencing provides high-resolution details of the clonal genomic modifications that occur during cancer initiation, progression, and ongoing evolution as patients undergo treatment. One limitation of current single-cell sequencing strategies is a suboptimal capacity to detect all classes of single-nucleotide and structural variants in the same cells.

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, ...

Ion implantation for deterministic single atom devices.

We demonstrate a capability of deterministic doping at the single atom level using a combination of direct write focused ion beam and solid-state ion detectors. The focused ion beam system can position a single ion to within 35 nm of a targeted location and the detection system is sensitive to single low energy heavy ions. This platform can be used to deterministically fabricate single atom devices in materials where the nanostructure and ion detectors can be integrated, including donor-based qubits in Si a...

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...

In Situ Scatheless Cell Detachment Reveals Connections Between Adhesion Strength and Viability at Single-Cell Resolution.

Single-cell biology provides insights to some of the most fundamental processes in biology and promotes the understanding of life's mysteries. And as the technologies to study single-cells expand, they will require sophisticated analytical tools to make sense of various behaviors and components of single-cells as well as their relations in adherent tissue culture. In this paper, we revealed cell heterogeneity and uncovered the connections between cell adhesion strength and cell viability at single-cell reso...

Single-Crystal-to-Single-Crystal Post-Synthetic Modification of a Metal-Organic Framework via Ozonolysis.

We describe solid-gas phase, single-crystal-to-single-crystal, post-synthetic modifications of a Metal-Organic Framework (MOF). Using ozone, we quantitatively transformed the olefin groups of a UiO-66-type MOF into 1,2,4-trioxolane rings, which we then selectively converted into either aldehydes or carboxylic acids.

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...

The three betrayals of the medical cannabis growing activist: From multiple victimhood to reconstruction, redemption and activism.

While cannabis has been widely used in the UK for over 50 years, it is only in recent decades that domestic cultivation has become established. Public concern, media reporting and policing policy has emphasised the role of profit motivated criminal organisations often working on a large scale and with coerced labour. However, increasingly, another population are growing for medical reasons, to help themselves and others treat or manage difficult, poorly understood, or incurable conditions. Our study sought ...

Mapping gene regulatory networks from single-cell omics data.

Single-cell techniques are advancing rapidly and are yielding unprecedented insight into cellular heterogeneity. Mapping the gene regulatory networks (GRNs) underlying cell states provides attractive opportunities to mechanistically understand this heterogeneity. In this review, we discuss recently emerging methods to map GRNs from single-cell transcriptomics data, tackling the challenge of increased noise levels and data sparsity compared with bulk data, alongside increasing data volumes. Next, we discuss ...

Doughnut-shaped emission from vertical organic nanowire coupled to thin plasmonic film.

Vertical nanowires facilitate an innovative mechanism to channel the optical field in the orthogonal direction and act as a nanoscale light source. Subwavelength, vertically oriented nanowire platforms, both of plasmonic and semiconducting variety, can facilitate interesting far-field emission profiles and potentially carry orbital angular momentum states. Motivated by these prospects, in this Letter, we show how a hybrid plasmonic-organic platform can be harnessed to engineer far-field radiation. The syste...

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...

Advances in single quantum dot-based nanosensors.

Single-molecule detection provides a simple and ultrasensitive platform to quantify target molecules by simply counting the individual fluorescence signals. Quantum dots (QDs) are novel semiconductor nanocrystals with distinct characteristics of high brightness, large Stokes shift and broad absorption spectra, high molar extinction coefficients, high quantum yield, good photostability and long fluorescence lifetime. The combination of single-molecule detection with QDs enables the development of single QD-b...

Clustering single cells: a review of approaches on high-and low-depth single-cell RNA-seq data.

Clinical Inquiry: Is megestrol acetate safe and effective for malnourished nursing home residents?

No. Megestrol acetate (MA) is neither safe nor effective for stimulating appetite in malnourished nursing home residents. It increases the risk of deep vein thrombosis (strength of recommendation [SOR]: C, 2 retrospective chart reviews), but isn't associated with other new or worsening events or disorders (SOR: B, single randomized controlled trial [RCT]). Over a 25-week period, MA wasn't associated with increased mortality (SOR: B, single RCT). After 44 months, however, MA-treated patients showed decreased...
