Improving Direct Yaw-Moment Control via Neural-Network-Based Non-Singular Fast Terminal Sliding Mode Control for Electric Vehicles.

Given the increased significance of electric vehicles in recent years, this study aimed to develop a novel form of direct yaw-moment control (DYC) to enhance the driving stability of four-wheel independent drive (4WID) electric vehicles. Specifically, this study developed an innovative non-singular fast terminal sliding mode control (NFTSMC) method that integrates NFTSM and a fast-reaching control law. Moreover, this study employed a radial basis function neural network (RBFNN) to approximate both the entire system model and uncertain components, thereby reducing the computational load associated with a complex system model and augmenting the overall control performance.

Metabolomic and transcriptomic study to understand changes in metabolic and immune responses in steers under heat stress.

Heat stress (HS) damages livestock by adversely affecting physiological and immunological functions. However, fundamental understanding of the metabolic and immunological mechanisms in animals under HS remains elusive, particularly in steers. To understand the changes on metabolic and immune responses in steers under HS condition, we performed RNA-sequencing and proton nuclear magnetic resonance spectroscopy-based metabolomics on HS-free (THI value: 64.

Dynamic changes in blood immune cell composition and function in Holstein and Jersey steers in response to heat stress.

Heat stress has detrimental effects on livestock via diverse immune and physiological changes; heat-stressed animals are rendered susceptible to diverse diseases. However, there is relatively little information available regarding the altered immune responses of domestic animals in heat stress environments, particularly in cattle steers. This study aimed to determine the changes in the immune responses of Holstein and Jersey steers under heat stress.

15-Hydroxyprostaglandin dehydrogenase inhibitor prevents contrast-induced acute kidney injury.

The two primary mechanisms by which iodinated contrast media (CM) causes contrast-induced acute kidney injury (CIAKI) are the hemodynamic effect causing intrarenal vasoconstriction and the tubular toxic effect causing acute tubular necrosis. Inhibition of 15-hydroxyprostaglandin dehydrogenase (15-PGDH), which degrades prostaglandin E (PGE2), promotes tissue repair and regeneration in many organs. PGE2 causes intrarenal arterial vasodilation.

Inhibition of 15-PGDH prevents ischemic renal injury by the PGE/EP signaling pathway mediating vasodilation, increased renal blood flow, and increased adenosine/A receptors.

In the present study, we demonstrated the marked activity of SW033291, an inhibitor of 15-hydoxyprostaglandin dehydrogenase (15-PGDH), in preventing acute kidney injury (AKI) in a murine model of ischemia-reperfusion injury. AKI due to ischemic injury represents a significant clinical problem. PGE is vasodilatory in the kidney, but it is rapidly degraded in vivo due to catabolism by 15-PGDH.

Hydrolyzed Yeast Supplementation in Calf Starter Promotes Innate Immune Responses in Holstein Calves under Weaning Stress Condition.

Weaned calves are susceptible to infectious diseases because of the stress and malnutrition that occurs during weaning. Therefore, the dairy industry requires effective feed additives to ameliorate stress responses and promote immunity. This study aimed to investigate the effects of hydrolyzed yeast (HY) supplementation on the growth performance, immune and stress parameters, and health status of calves after weaning.

Association between epidermal growth factor (EGF) and EGF receptor gene polymorphisms and end-stage renal disease and acute renal allograft rejection in a Korean population.

Epidermal growth factor (EGF) has been found to be associated with the development and repair mechanisms of several renal diseases. In this study, we hypothesized that single nucleotide polymorphisms (SNPs) in EGF or its receptor genes might have an association with end-stage renal disease (ESRD) or acute renal allograft rejection (AR) in a Korean population. Three-hundred and forty seven recipients of the first renal transplants for ESRD, including 63 AR patients along with 289 healthy adults were included in the study.

Study Design: Retrospective analysis of prospective observational cohort OBJECTIVE.: This study assessed the difference in health-related quality of life (HRQOL) between participants with a mild to moderate adult sagittal deformity (ASD) (sagittal vertical axis [SVA] ≤9.5 cm) and those with a marked deformity (SVA >9.

Effect of Converting From Calcineurin Inhibitor- to Sirolimus-Based Immunosuppressant Regimen on Breast Fibroadenoma Among Kidney Transplant Patients.

The incidence rate of breast fibroadenomas is higher among female kidney transplant (KT) patients treated using cyclosporine (CsA) for immunosuppression than in the general population. As such, there is an effort to convert immunosuppression from CsA or tacrolimus to sirolimus. Our aim was to assess the reversibility of a breast fibroadenoma after conversion in a small cohort of female KT recipients.

The effect of heat stress on frame switch splicing of X-box binding protein 1 gene in horse.

Objective: Among stress responses, the unfolded protein response (UPR) is a well-known mechanism related to endoplasmic reticulum (ER) stress. ER stress is induced by a variety of external and environmental factors such as starvation, ischemia, hypoxia, oxidative stress, and heat stress. Inositol requiring enzyme 1α (IRE1α)-X-box protein 1 (XBP1) is the most conserved pathway involved in the UPR and is the main component that mediates IRE1α signalling to downstream ER-associated degradation (ERAD)- or UPR-related genes.

The unit price of a cow was estimated from the following parameters: -52.

Influences of somatic donor cell sex on and embryo development following somatic cell nuclear transfer in pigs.

Objective: The present study investigates pre- and post-implantation developmental competence of nuclear-transferred porcine embryos derived from male and female fetal fibroblasts.

Methods: Male and female fetal fibroblasts were transferred to -matured enucleated oocytes and and developmental competence of reconstructed embryos was investigated. And, a total of 6,789 female fibroblast nuclear-transferred embryos were surgically transferred into 41 surrogate gilts and 4,746 male fibroblast nuclear-transferred embryos were surgically transferred into 25 surrogate gilts.

A case of ampullary gangliocytic paraganglioma.

Gangliocytic paragangliomas (GPs) are rare tumors of the duodenum, presenting as single sessile or pedunculated polypoid masses. Clinical manifestations of duodenal GPs can vary from an incidental finding at endoscopy to frequent upper gastrointestinal bleeding caused by mucosal ulceration and abdominal pain. GPs are considered benign, but the disease can recur and spread to regional lymph nodes.

Investigation of de novo unique differentially expressed genes related to evolution in exercise response during domestication in Thoroughbred race horses.

Previous studies of horse RNA-seq were performed by mapping sequence reads to the reference genome during transcriptome analysis. However in this study, we focused on two main ideas. First, differentially expressed genes (DEGs) were identified by de novo-based analysis (DBA) in RNA-seq data from six Thoroughbreds before and after exercise, here-after referred to as "de novo unique differentially expressed genes" (DUDEG).

Binding mode analyses and pharmacophore model development for stilbene derivatives as a novel and competitive class of α-glucosidase inhibitors.

Stilbene urea derivatives as a novel and competitive class of non-glycosidic α-glucosidase inhibitors are effective for the treatment of type II diabetes and obesity. The main purposes of our molecular modeling study are to explore the most suitable binding poses of stilbene derivatives with analyzing the binding affinity differences and finally to develop a pharmacophore model which would represents critical features responsible for α-glucosidase inhibitory activity.

The effects of artificial activation timing on the development of SCNT-derived embryos and newborn piglets.

This study investigated the effects of two different activation regimens on the developmental potential of somatic cell nuclear transfer (SCNT) embryos and postnatal survivability of the cloned piglets. In vitro matured oocytes were enucleated and reconstructed with porcine fetal fibroblasts. On the basis of the activation regimen used, the reconstructed porcine embryos were allocated into two groups: Group 1-simultaneous electrical pulses and activation group (SFA group); and Group 2-electrical fusion without calcium followed by electrical pulses with calcium after colcemid and cytochalasin B treatment for 5h (DA group).

Proteomic identification of abnormally expressed proteins in early-stage placenta derived from cloned cat embryos.

It is unknown whether gene expression in cloned placenta during pre- and postimplantation is associated with early pregnancy failure in the cat. In this study, protein expression patterns were examined in early-stage (21-day-old) domestic cat placentas of fetuses derived from AI (CP; N = 4) and cloned embryo transfer (CEP; N = 2). Differentially expressed proteins were analyzed by two-dimensional gel electrophoresis and matrix-assisted laser desorption/ionization time-of-flight (TOF) mass spectrometry (MS).

RNA-Seq approach for genetic improvement of meat quality in pig and evolutionary insight into the substrate specificity of animal carbonyl reductases.

Changes in meat quality traits are strongly associated with alterations in postmortem metabolism which depend on genetic variations, especially nonsynonymous single nucleotide variations (nsSNVs) having critical effects on protein structure and function. To selectively identify metabolism-related nsSNVs, next-generation transcriptome sequencing (RNA-Seq) was carried out using RNAs from porcine liver, which contains a diverse range of metabolic enzymes. The multiplex SNV genotyping analysis showed that various metabolism-related genes had different nsSNV alleles.

Non-synonymous SNP in the ApoR gene associated with pork meat quality.

Two novel non-synonymous SNPs in the 2nd and 3rd exons of the porcine ApoR gene are reported. One was identified as a novel SNP significantly associated with multiple traits of pork meat quality. The data can provide a useful resource for developing a marker in the genetic improvement of pigs.

Enhanced histone acetylation in somatic cells induced by a histone deacetylase inhibitor improved inter-generic cloned leopard cat blastocysts.

The objective was to determine whether alterations of histone acetylation status in donor cells affected inter-generic SCNT (igSCNT)-cloned embryo development. Leopard cat cells were treated with trichostatin A (TSA; a histone deacetylase inhibitor) for 48 h, and then donor cells were transferred into enucleated oocytes from domestic cats. Compared to non-treated cells, the acetylated histone 3 at lysine 9 (AcH3K9) and histone 4 at lysine 5 (AcH4K5) in the TSA group increased for up to 48 h (P < 0.

Use of microsatellite markers to detect quantitative trait loci in Yorkshire pigs.

To identify genetic markers associated with economic traits in pigs, 157 microsatellite markers were examined in Yorkshire pigs. Thirty eight female Yorkshire pigs were initially examined and six of them were selected as progenitors; half were more than 1.5 standard deviations (SD) above the mean for average daily gain (ADG) and backfat thickness (BFT), and the remaining half were more than 1.
