Prevalence and risk factors of possible sarcopenia in patients with subacute stroke

Plos.org 

by Yeo Hyung Kim, Young-Ah Choi

Possible sarcopenia, the loss of handgrip strength in the older population, can lead to poor functional prognosis after stroke. In this retrospective study, we aimed to elucidate the clinical risk factors for possible sarcopenia at discharge in 152 hospitalized patients with subacute stroke. Univariable and multivariable logistic regression analysis was performed to determine the risk factors associated with possible sarcopenia. At the time of discharge, the... Читать дальше...

Shotgun metagenomics captures more microbial diversity than targeted 16S rRNA gene sequencing for field specimens and preserved museum specimens

Plos.org 

by Joseph D. Madison, Brandon C. LaBumbard, Douglas C. Woodhams

The use of museum specimens for research in microbial evolutionary ecology remains an under-utilized investigative dimension with important potential. Despite this potential, there remain barriers in methodology and analysis to the wide-spread adoption of museum specimens for such studies. Here, we hypothesized that there would be significant differences in taxonomic prediction and related diversity among sample type (museum... Читать дальше...

Examining the subjective fairness of at-home and online tests: Taking Duolingo English Test as an example

Plos.org 

by Don Yao

The Duolingo English Test, a language proficiency test offered online, is now getting prevalent worldwide. A recap of existing literature denotes that there is an insufficient examination of the DET, particularly on its issues of fairness. Besides, empirical test fairness research had mainly focused on the objective aspect but may have overlooked the importance of its subjective aspect. Additionally, compared with in-person tests, the fairness research of at-home tests lags far behind. Читать дальше...

Identification of M2-like macrophage-related signature for predicting the prognosis, ecosystem and immunotherapy response in hepatocellular carcinoma

Plos.org 

by Qian Feng, Hongcheng Lu, Linquan Wu

Background

Hepatocellular carcinoma is one of the most common malignancies worldwide, representing a big health-care challenge globally. M2-like macrophages are significantly correlated with tumor progression, metastasis and treatment resistance.

Methods

Integrative 10 machine learning algorithms were performed to developed a M2-like macrophage related prognostic signature (MRPS). Single-cell RNA-sequencing analysis was performed to dissect the ecosystem of HCC. Читать дальше...

Efficacy of nonpharmacological interventions targeting social function in children and adults with autism spectrum disorder: A systematic review and meta-analysis

Plos.org 

by Zhili Yu, Peiming Zhang, Chenyang Tao, Liming Lu, Chunzhi Tang

Background and aims

This paper aimed to evaluate the use of nonpharmacological interventions for the management of autism spectrum disorder (ASD). The effects of acupuncture and behavioural therapy, two nonpharmalogical interventions, on social function in ASD patients are still controversial. This meta-analysis investigated the impact of these two treatments and compared their effects.

Methods

Seven electronic databases... Читать дальше...

Image generation technology for functional occlusal pits and fissures based on a conditional generative adversarial network

Plos.org 

by Zhaodan Gu, Zhilei Wu, Ning Dai

The occlusal surfaces of natural teeth have complex features of functional pits and fissures. These morphological features directly affect the occlusal state of the upper and lower teeth. An image generation technology for functional occlusal pits and fissures is proposed to address the lack of local detailed crown surface features in existing dental restoration methods. First, tooth depth image datasets were constructed using an orthogonal projection method. Читать дальше...

Cropland expansion in Ecuador between 2000 and 2016

Plos.org 

by José I. Ochoa-Brito, Aniruddha Ghosh, Robert J. Hijmans

We describe changes in the cropland distribution for physiographic and bioregions of continental Ecuador between 2000 and 2016 using Landsat satellite data and government statistics. The cloudy conditions in Ecuador are a major constraint to satellite data analysis. We developed a two-stage cloud filtering algorithm to create cloud-free multi-temporal Landsat composites that were used in a Random Forest model to identify cropland. Читать дальше...

Comprehensive transcriptomic analysis of long non-coding RNAs in bovine ovarian follicles and early embryos

Plos.org 

by Pengmin Wang, Éric R. Paquet, Claude Robert

Long non-coding RNAs (lncRNAs) have been the subject of numerous studies over the past decade. First thought to come from aberrant transcriptional events, lncRNAs are now considered a crucial component of the genome with roles in multiple cellular functions. However, the functional annotation and characterization of bovine lncRNAs during early development remain limited. In this comprehensive analysis, we review lncRNAs expression in bovine ovarian follicles and early embryos... Читать дальше...

Historical biogeography supports Point Conception as the site of turnover between temperate East Pacific ichthyofaunas

Plos.org 

by Elizabeth Christina Miller

The cold temperate and subtropical marine faunas of the Northeastern Pacific meet within California as part of one of the few eastern boundary upwelling ecosystems in the world. Traditionally, it is believed that Point Conception is the precise site of turnover between these two faunas due to sharp changes in oceanographic conditions. However, evidence from intraspecific phylogeography and species range terminals do not support this view, finding stronger biogeographic breaks elsewhere along the coast. Читать дальше...

A hypernetwork-based urn model for explaining collective dynamics

Plos.org 

by Jiali Lu, Haifeng Du, Xiaochen He

The topological characterization of complex systems has significantly contributed to our understanding of the principles of collective dynamics. However, the representation of general complex networks is not enough for explaining certain problems, such as collective actions. Considering the effectiveness of hypernetworks on modeling real-world complex networks, in this paper, we proposed a hypernetwork-based Pólya urn model that considers the effect of group identity.

Adaptation and measurement invariance of the 13-item version of Patient Activation Measure across Japanese young adult cancer survivors during and after treatment: A cross-sectional observational study

Plos.org 

by Takafumi Soejima, Mari Kitao

The 13-item version of the Patient Activation Measure (PAM-13) is a frequently used measure that gauges the level of self-management in an individual. However, its applicability across Japanese young adult (YA) cancer survivors during and after their treatment remains unclear. This study confirmed the psychometric properties and measurement invariance of the Japanese version of PAM-13 across them during and after treatment. We used cross-sectional observational...

Understanding consumers’ intentions to purchase smart clothing using PLS-SEM and fsQCA

Plos.org 

by Shucong Chen, Jing Ye

With the advancement of artificial intelligence (AI) and the Internet of Things (IoT), smart clothing, which has enormous growth potential, has developed to suit consumers’ individualized demands in various areas. This paper aims to construct a model that integrates that technology acceptance model (TAM) and functionality-expressiveness-aesthetics (FEA) model to explore the key factors influencing consumers’ smart clothing purchase intentions (PIs). Partial least... Читать дальше...
