Exercise capacity is a valuable trait in horses, and it has been used as one of their selection criteria. Although exercise affects molecular homeostasis and adaptation in horses, the mechanisms underlying these effects are not fully understood. This study was carried out to identify changes in the blood profiles of microRNAs (miRNAs) and mRNAs induced by exercise in horse leukocytes. Total RNAs isolated from the peripheral blood leukocytes of four Warmblood horses before and after exercise were subjected to next-generation sequencing (NGS) and microarray analyses to determine the miRNA and mRNA expression profiles, respectively...

Gefitinib resistance and relapse of the disease were the greatest challenges facing clinical therapy of non-small-cell lung cancer (NSCLC). Of note, regarding the hypoxia condition in solid tumor tissues in vivo, roles of hypoxia in gefitinib adaptive resistance and its association with lung cancer stem cells (LCSCs) have not been fully elucidated. In the present study, the role of hypoxia in gefitinib adaptive resistance and its association with aldehyde dehydrogenase (ALDH)-based LCSC gefitinib resistance were comparatively studied using RNA-sequencing (RNA-seq) technology...

In recent years, the smart home field has gained wide attention for its broad application prospects. However, families using smart home systems must usually adopt various heterogeneous smart devices, including sensors and devices, which makes it more difficult to manage and control their home system. How to design a unified control platform to deal with the collaborative control problem of heterogeneous smart devices is one of the greatest challenges in the current smart home field. The main contribution of this paper is to propose a universal smart home control platform architecture (IAPhome) based on a multi-agent system and communication middleware, which shows significant adaptability and advantages in many aspects, including heterogeneous devices connectivity, collaborative control, human-computer interaction and user self-management...

In order to improve the classification accuracy of recognizing short-circuit faults in electric transmission lines, a novel detection and diagnosis method based on empirical wavelet transform (EWT) and local energy (LE) is proposed. First, EWT is used to deal with the original short-circuit fault signals from photoelectric voltage transformers, before the amplitude modulated-frequency modulated (AM-FM) mode with a compactly supported Fourier spectrum is extracted. Subsequently, the fault occurrence time is detected according to the modulus maxima of intrinsic mode function (IMF₂) from three-phase voltage signals processed by EWT...

REVIEW
Edward C Schrom, Andrea L Graham
Over recent years, extensive phenotypic variability and plasticity have been revealed among the T-helper cells of the mammalian adaptive immune system, even within clonal lineages of identical antigen specificity. This challenges the conventional view that T-helper cells assort into functionally distinct subsets following differential instruction by the innate immune system. We argue that the adaptive value of coping with uncertainty can reconcile the 'instructed subset' framework with T-helper variability and plasticity...

OBJECTIVE: Performance monitoring, which allows efficient behavioral regulation using either internal (error processing) or external (feedback processing) cues, has not yet been explored in binge drinking despite its adaptive importance in everyday life, particularly in the regulation of alcohol consumption. Capitalizing on a theoretical model of risky behaviors, the present study aimed at determining the behavioral and electrophysiological correlates of the cognitive (inhibition) and motivational (reward sensitivity) systems during performance monitoring...

BACKGROUND: Malignant peripheral nerve sheath tumor (MPNST) is one of the most common nonrhabdomyosarcoma soft tissue sarcomas encountered in pediatric age, and it is generally characterized by poor outcome, particularly for relapsing patients. MATERIALS AND METHODS: This study considered 73 patients <21 years of age with relapsing MPNST observed among 120 patients enrolled in Italian pediatric protocols from 1979 to 2004. With the aim of possibly establishing a risk-adapted stratification, patients' outcome was examined using univariate and multivariate analysis based on clinical features at onset, first-line treatments, clinical findings at the time of first relapse, and second-line treatments...

Adapting methods from complex system analysis, this paper analyzes the features of the complex relationship between wage inequality and the development and industrialization of a country. Development is understood as a combination of a monetary index, GDP per capita, and a recently introduced measure of a country's economic complexity: Fitness. Initially the paper looks at wage inequality on a global scale, over the time period 1990-2008. Our empirical results show that globally the movement of wage inequality along with the ongoing industrialization of countries has followed a longitudinally persistent pattern comparable to the one theorized by Kuznets in the fifties: countries with an average level of development suffer the highest levels of wage inequality...

REVIEW
Daniel H Kaplan
Langerhans cells (LCs) are epidermis-resident antigen-presenting cells that share a common ontogeny with macrophages but function as dendritic cells (DCs). Their development, recruitment and retention in the epidermis is orchestrated by interactions with keratinocytes through multiple mechanisms. LC and dermal DC subsets often show functional redundancy, but LCs are required for specific types of adaptive immune responses when antigen is concentrated in the epidermis. This Review will focus on those developmental and functional properties that are unique to LCs...

The immune system is characterized by the generation of structurally and functionally heterogeneous immune cells that constitute complex innate and adaptive immunity. This heterogeneity of immune cells results from changes in the expression of genes without altering DNA sequence. To achieve this heterogeneity, immune cells orchestrate the expression and functional status of transcription factor (TF) networks, which can be broadly categorized into 3 classes: pioneer TFs that facilitate initial commitment and differentiation of hematopoietic cells, subset-specific TFs that promote the generation of selected cell lineages, and immune-signaling TFs that regulate specialized function in differentiated cells...

: Natural killer (NK) cells are important effectors of innate immunity playing a key role in the eradication and clearance of viral infections. Over the recent years, several studies have shown that HIV-1 pathologically changes NK cell homeostasis and hampers their antiviral effector functions. Moreover, high levels of chronic HIV-1 viremia markedly impair those NK cell regulatory features that normally regulate the cross-talks between innate and adaptive immune responses. These pathogenic events take place early in the infection and are associated with a pathologic redistribution of NK cell subsets that includes the expansion of anergic CD56 NK cells with an aberrant repertoire of activating and inhibitory receptors...

BACKGROUND: In 2010, Ontario, Canada's most populous province, implemented its Toxics Reduction Act, Ontario Regulation 455/09 (TRA), which requires four major manufacturing and mineral processing industry groups that already report releases of pollutants federally to the National Pollutant Release Inventory to additionally track, account and report their use and creation. The TRA was modeled after the Massachusetts Toxics Use Reduction Act of 1989, which has been very successful and reported significant reduction in toxic use and carcinogen release...

Multidisciplinary treatment programs for patients with personality disorders (PDs) often include art therapy, but the efficacy of this intervention has hardly been evaluated. The objective of this study is to evaluate the effects of an art therapy intervention on psychological functioning of patients with a PD. In this randomized controlled trial, 57 adult participants diagnosed with a PD cluster B/C (SCID-II) were randomly assigned to either weekly group art therapy (1.5 hours, 10 weeks) or a waiting list group...

Phenotypic plasticity allows organisms to adapt quickly to local environmental conditions and could facilitate adaptive radiations. Cichlids have recently undergone an adaptive radiation in Lake Malawi where they inhabit diverse light environments and tune their visual sensitivity through differences in cone opsin expression. While cichlid opsin expression is known to be plastic over development, whether adults remain plastic is unknown. Adult plasticity in visual tuning could play a role in cichlid radiations by enabling survival in changing environments and facilitating invasion into novel environments...

The notorious plasticity of gene expression responses and the complexity of environmental gradients complicate the identification of adaptive differences in gene regulation among populations. We combined transcriptome analyses in nature with common garden and exposure experiments to establish cause and effect relationships between the presence of a physiochemical stressor and expression differences, as well as to test how evolutionary change and plasticity interact to shape gene expression variation in natural systems...

Despite its explosive applications in genome engineering, CRISPR (Clustered Regularly Interspersed Short Palindromic Repeats) has been developed into a versatile tool beyond its well-known nuclease function. In this prospect article, we summarize a few exciting "off-label" applications of CRISPR including manipulating DNA sequences, visualizing chromosomal loci in living cells, and modulating transcription and chromatin structures. These novel applications will likely elevate CRISPR tools into yet another level of sophistication and diversity, leading to many more exciting cell biological discoveries...

Poaching can have devastating impacts on animal and plant numbers, and in many countries has reached crisis levels, with illegal hunters employing increasingly sophisticated techniques. Here, we show how geographic profiling - a mathematical technique originally developed in criminology and recently applied to animal foraging and epidemiology - can be adapted for use in investigations of wildlife crime, using data from an eight-year study in Savé Valley Conservancy, Zimbabwe that in total includes more than 10,000 incidents of illegal hunting and the deaths of 6,454 wild animals...

Alloimmunity traditionally distinguishes short-lived, rapid and non-specific innate immune responses from adaptive immune responses that are characterized by a highly specific response initiated in a delayed fashion. Key players of innate immunity such as natural killer (NK) cells and macrophages present the first-line defense of immunity. The concept of unspecific responses in innate immunity has recently been challenged. The discovery of pattern recognition receptors (PRRs) has demonstrated that innate immune cells respond in a semi-specific fashion through the recognition of pathogen-associated molecular patterns (PAMPs) representing conserved molecular structures shared by large groups of microorganisms...

Dental microwear textures have been examined for a broad range of extant primates to assess their efficacy for reconstructing diets of fossil species. To date though, no dental microwear texture data have been published for pitheciid molars, despite reported variation in degree of sclerocarpy and, by extension, the fracture properties of foods these platyrrhines eat. While all pitheciids eat hard or tough seeds, Chiropotes and Pithecia have been documented to consume more than Callicebus. In this study, we explored whether measures of molar microwear texture complexity discriminate taxa following variation in reliance upon seeds, and whether dispersion among variables is greatest in Callicebus, which has the most variable diet...
