No evidence for adult smartphone use affecting attribution of communicative intention in toddlers: Online imitation study using the Sock Ball Task

Plos.org 

by Solveig Flatebø, Gabriella Óturai, Mikołaj Hernik

Adults infer others’ communicative intentions, or lack thereof, from various types of information. Young children may be initially limited to attributions based on a small set of ostensive signals. It is unknown when richer pragmatic inferences about communicative intentions emerge in development. We sought novel type of evidence for such inferences in 17-to-19-month-olds. We hypothesized that toddlers recognize adults’ smartphone use in... Читать дальше...

Causal role of metabolites in non-small cell lung cancer: Mendelian randomization (MR) study

Plos.org 

by Qian Li, Zedong Wei, Yonglun Zhang, Chongqing Zheng

On a global scale, lung cancer(LC) is the most commonly occurring form of cancer. Nonetheless, the process of screening and detecting it in its early stages presents significant challenges. Earlier research endeavors have recognized metabolites as potentially reliable biomarkers for LC. However, the majority of these studies have been limited in scope, featuring inconsistencies in terms of the relationships and levels of association observed.Moreover... Читать дальше...

Taste dysfunction as a predictor of depression in schizophrenia: A systematic review and meta-analysis

Plos.org 

by Jia Liu, Shu-Jie Sun, Ye Lu, Xin Ping, Wan Zhang, Lin Pei

Objective

This study aims to investigate the relationship between taste dysfunction and depression among patients with schizophrenia, to achieve early detection of depression in clinical practice.

Methods

Following PRISMA guidance, a comprehensive literature search was conducted globally, covering papers published from 1961 to June 2023. A total of 17 manuscripts were selected through meta-analysis and sensitivity analysis... Читать дальше...



Chemical range recognized by the ligand-binding domain in a representative amino acid-sensing taste receptor, T1r2a/T1r3, from medaka fish

Plos.org 

by Hikaru Ishida, Norihisa Yasui, Atsuko Yamashita

Taste receptor type 1 (T1r) proteins are responsible for recognizing nutrient chemicals in foods. In humans, T1r2/T1r3 and T1r1/T1r3 heterodimers serve as the sweet and umami receptors that recognize sugars or amino acids and nucleotides, respectively. T1rs are conserved among vertebrates, and T1r2a/T1r3 from medaka fish is currently the only member for which the structure of the ligand-binding domain (LBD) has been solved. T1r2a/T1r3 is...

Constructing a student development model for undergraduate vocational universities in China using the Fuzzy Delphi Method and Analytic Hierarchy Process

Plos.org 

by Qiaona Xing, Huey Pyng Tan, Su Wan Gan

As the industrial structure changes, the severe shortage of high-quality technical and skilled talent in China is one of the most significant factors affecting the high-quality development of China’s economy. Bridging the gap between cultivating talent from new undergraduate vocational universities and the demand for industrial talent is regarded as an efficient strategy to address the talent shortage. In addressing the gap, China is hindered by a... Читать дальше...

Single-cell analysis reveals landscape of endometrial cancer response to estrogen and identification of early diagnostic markers

Plos.org 

by Chunli Dong, Liyan Zhao, Xiongtao Liu, Ling Dang, Xin Zhang

Background

The development of endometrial cancer (EC) is closely related to the abnormal activation of the estrogen signaling pathway. Effective diagnostic markers are important for the early detection and treatment of EC.

Method

We downloaded single-cell RNA sequencing (scRNA-seq) and spatial transcriptome (ST) data of EC from public databases. Enrichment scores were calculated for EC cell subpopulations using the “AddModuleScore” function and the AUCell package... Читать дальше...

Differing physiological performance of coexisting cool- and warmwater fish species under heatwaves in the Midwestern United States

Plos.org 

by Qihong Dai, Cory D. Suski

Heatwaves are becoming more frequent and intensified with climate change. Freshwater ecosystems are among the most threatened, within which, differing responses between cool- and warmwater species to heatwaves can lead to fundamental changes in communities. Physiological experiments can identify potential mechanisms underlying the impacts of such heatwaves on fish communities. In the current study, we quantified the oxygen consumption rate, aerobic scope and swimming... Читать дальше...

Plant growth-promoting bacteria potentiate antifungal and plant-beneficial responses of Trichoderma atroviride by upregulating its effector functions

Plos.org 

by Paulina Guzmán-Guzmán, Eduardo Valencia-Cantero, Gustavo Santoyo

Trichoderma uses different molecules to establish communication during its interactions with other organisms, such as effector proteins. Effectors modulate plant physiology to colonize plant roots or improve Trichoderma’s mycoparasitic capacity. In the soil, these fungi can establish relationships with plant growth–promoting bacteria (PGPBs), thus affecting their overall benefits on the plant or its fungal prey, and possibly, the role of effector proteins.

Compartment specific responses to contractility in the small intestinal epithelium

Plos.org 

by Taylor Hinnant, Wenxiu Ning, Terry Lechler

Tissues are subject to multiple mechanical inputs at the cellular level that influence their overall shape and function. In the small intestine, actomyosin contractility can be induced by many physiological and pathological inputs. However, we have little understanding of how contractility impacts the intestinal epithelium on a cellular and tissue level. In this study, we probed the cell and tissue-level effects of contractility by using mouse... Читать дальше...

Opticool: Cutting-edge transgenic optical tools

Plos.org 

by Kelli D. Fenelon, Julia Krause, Theodora Koromila

Only a few short decades have passed since the sequencing of GFP, yet the modern repertoire of transgenically encoded optical tools implies an exponential proliferation of ever improving constructions to interrogate the subcellular environment. A myriad of tags for labeling proteins, RNA, or DNA have arisen in the last few decades, facilitating unprecedented visualization of subcellular components and processes. Development of a broad array... Читать дальше...

Modelling and analysis of cAMP-induced mixed-mode oscillations in cortical neurons: Critical roles of HCN and M-type potassium channels

Plos.org 

by Matteo Martin, Morten Gram Pedersen

Cyclic AMP controls neuronal ion channel activity. For example hyperpolarization-activated cyclic nucleotide–gated (HCN) and M-type K+ channels are activated by cAMP. These effects have been suggested to be involved in astrocyte control of neuronal activity, for example, by controlling the action potential firing frequency. In cortical neurons, cAMP can induce mixed-mode oscillations (MMOs) consisting of small-amplitude, subthreshold oscillations separating complete action potentials... Читать дальше...

Detecting changes in generation and serial intervals under varying pathogen biology, contact patterns and outbreak response

Plos.org 

by Rachael Pung, Timothy W. Russell, Adam J. Kucharski

The epidemiological characteristics of SARS-CoV-2 transmission have changed over the pandemic due to emergence of new variants. A decrease in the generation or serial intervals would imply a shortened transmission timescale and, hence, outbreak response measures would need to expand at a faster rate. However, there are challenges in measuring these intervals. Alongside epidemiological changes, factors like varying delays in outbreak response... Читать дальше...
