Chemosensory Cues Modulate Women's Jealousy Responses to Vocal Femininity.

Jealousy responses to potential mating rivals are stronger when those rivals display cues indicating higher mate quality. One such cue is vocal femininity in women's voices, with higher-pitched voices eliciting greater jealousy responses. However, cues to mate quality are not evaluated in isolation.

Testosterone administration decreases sensitivity to angry facial expressions in healthy males: A computational modeling approach.

Previous research indicates that higher testosterone levels are related to increased aggressive and dominant behaviors, particularly in males. One possible mechanism for these hormone-behavior associations could involve threat perception. However, the causal influence of testosterone on men's recognition of threatening facial expressions remains unknown.

Novel NIR fluorescent probe for hypochlorite ion detection in biological systems.

This study presents the synthesis and application of a novel fluorescent probe, NR-ClO, for the detection of hypochlorite ion (ClO) in biological systems. The probe was synthesized through a nucleophilic substitution reaction between Nile red and dimethylcarbamothioic chloride. The synthesized probe had high sensitivity and selectivity towards ClO, with a detection limit of 75 nM and a linear range of 0.

Dataset construction method of cross-lingual summarization based on filtering and text augmentation.

Existing cross-lingual summarization (CLS) datasets consist of inconsistent sample quality and low scale. To address these problems, we propose a method that jointly supervises quality and scale to build CLS datasets. In terms of quality supervision, the method adopts a multi-strategy filtering algorithm to remove low-quality samples of monolingual summarization (MS) from the perspectives of character and semantics, thereby improving the quality of the MS dataset.

Sex-specific effects of human chemosignal on perception of angry but not fearful faces.

Androsta-4,16,-dien-3-one (androstadienone), a steroids implicated as a human social chemosignal, has been reported to impact one's emotional perception along the valence axis. The current study takes a step further to examine whether it modulates the perception of angry and fearful faces, two negative emotions that are similar with respect to valence and arousal, but signal different social values. Systematic comparisons of psychophysical data collected from 40 heterosexual men and 45 heterosexual women revealed that androstadienone subconsciously biased heterosexual men toward perceiving the male faces as less angry, while it biased the heterosexual women toward perceiving the female faces as angrier.

Can testosterone modulate prosocial learning in healthy males? A double-blind, placebo-controlled, testosterone administration study.

Testosterone is associated with both aggressive and prosocial behavior, which depend on the social context and the trade-off between self- and other-interest. However, little is known about the effects of testosterone on prosocial behavior in a context without such trade-offs. The present study aimed to investigate the effects of exogenous testosterone on prosocial behavior by using a prosocial learning task.

Androstadienone modulates human aggression in a sex-dependent manner.

Chemosensory communication is ubiquitous in human social interaction. Androstadienone is a potential candidate human sex pheromone that is associated with social dominance and competition. The aim of the present study was to investigate the effects of androstadienone on aggression.

Functionalized graphene oxide/sodium alginate beads with ion responsiveness for uranium trapping.

Uranium as a strategic and non-renewable resource has been paid close attention to its efficient recovery and reuse from uranium-containing wastewater. Here, a composite bead was prepared by functionalized graphene oxide and sodium alginate (L-Lys-GO/SA) with ion-stimuli responsiveness for achieving U(VI) adsorption. The L-Lys-GO/SA-60 composite beads can selectively adsorb U(VI) with the maximum adsorption capacity (q) of 704.

Prenatal diagnosis of isolated lateral facial cleft by ultrasonography and three-dimensional printing: A case report.

Background: Lateral facial clefts are atypical with a low incidence in the facial cleft spectrum. With the development of ultrasonography (US) prenatal screening, such facial malformations can be detected and diagnosed prenatally rather than at birth. Although three-dimensional US (3DUS) can render the fetus' face 3D reconstruction, the 3D images are displayed on two-dimensional screens without field depth, which impedes the understanding of untrained individuals.

Amino Acid Cross-Linked Graphene Oxide Membranes for Metal Ions Permeation, Insertion and Antibacterial Properties.

Graphene oxide (GO) and its composite membranes have exhibited great potential for application in water purification and desalination. This article reports that a novel graphene oxide membrane (GOM) of ~5 µm thickness was fabricated onto a nylon membrane by vacuum filtration and cross-linked by amino acids (L-alanine, L-phenylalanine, and serine). The GOM cross-linked by amino acids (GOM-A) exhibits excellent stability, high water flux, and high rejection to metal ions.

Exogenous testosterone decreases men's sensitivity to vocal cues of male dominance.

Assessing dominance is important for effective social interactions, and prior research suggests that testosterone is associated with men's dominance perceptions. The present study tested for a causal effect of exogenous testosterone on men's sensitivity to vocal cues of other men's dominance, an important parameter in male-male competition across species. One hundred and thirty-nine Chinese men received a single dose (150 mg) of testosterone or placebo gel in a double-blind, placebo-controlled, between-participant design.

Obstetric and neonatal outcomes of delayed interval delivery in cerclage: A retrospective study.

Objective: Delayed delivery is sometimes selectively performed in twin pregnancy when the first birth occurs inevitably in order to improve the prognosis and decrease the morbidity and mortality of the second twin. The aim of this study is to explore the maternal and fetal outcomes of pregnancies in which cerclage is carried out following the loss of first fetus in twin gestation for delayed interval delivery.

Methods: Three cases of delayed-interval delivery of dichorionic-diamniotic twin pregnancies were reported in our center between 2017 and 2018 and were retrospectively analyzed.

Effect of a New Model-Based Reconstruction Algorithm for Evaluating Early Peripheral Lung Cancer With Submillisievert Chest Computed Tomography.

Objective: The aim of this study was to compare a new model-based iterative reconstruction algorithm with either spatial and density resolution balance (MBIRSTND) or spatial resolution preference (MBIRRP20) with the adaptive statistical iterative reconstruction (ASIR) in evaluating early small peripheral lung cancer (SPLC) with submillisievert chest computed tomography (CT).

Methods: Low-contrast and spatial resolutions were assessed in a phantom and with 30 pathologically confirmed SPLC patients. Images were reconstructed using 40% ASIR, MBIRSTND, and MBIRRP20.

Impact of the chemical and physical stability of ketoprofen compounded in various pharmaceutical bases on its topical and transdermal delivery.

Increasing demands for individualized drug treatment has led to an increase in the practice of compounded medications. In this study, we determined the impact of the chemical and physical stability of ketoprofen (10%w/w) cream on its topical/transdermal delivery over a 6-month period. The shelf life of ketoprofen at 25 °C in the pharmaceutical bases LipoDerm and LipoBase (109.
