Presents a uniform approach to various engineering problems, such as analysis and synthesis of electrical networks, sampled-data feedback, control systems, switching networks, and communications nets

This study investigates the feasibility of using an adipose-derived mesenchymal stem cell (ASC)-seeded acellular dermal matrix (ADM) along with low-level laser therapy (LLLT) to repair bone defect in athymic nude mice. Critical-sized calvarial defects were treated either with ADM, ADM/LLLT, ADM/ASCs, or ADM/ASCs/LLLT. In micro-computed tomography scans, the ADM/ASCs and the ADM/ASCs/LLLT groups showed remarkable bone formation after 14 days. Additionally, bone regeneration in the ADM/ASCs/LLLT g

Leptin and its receptor play several physiological roles in the canine gallbladder, and the dysregulation of leptin might play a role in the pathogenesis of gallbladder diseases such as gallbladder mucocele. Previous studies revealed a positive association between hyperlipidemia and gallstones in humans. However, the latter is still unclear in dogs with cholelithiasis. In this study, we examined the differences in leptin, leptin receptor, total cholesterol, and triglyceride levels between health

This study suggests that SPRA is feasible and can be used to resect small adrenal tumors with minimal complications.

The purpose of this study is to evaluate the effect of acellular dermal matrix (ADM) as a delivery carrier of adipose-derived mesenchymal stem cells (ASCs) on bone regeneration in athymic murine calvarial bone defect. Paired-critical size defects in nude rat skull were made. The right-side defects received ASCs/ADM or only ADM, whereas the left-side defect was not treated. In 3D images, new bone formation in the ASCs/ADM group was apparent at 4 wk, but in the ADM group at 8 wk. At 4 and 8 wk, bo

The retroperitoneal access technique and working space establishment with CO₂ insufflation starting with 5 mmHg and increasing to 10 mmHg provided adequate working space and visualization of retroperitoneal organs, which may allow direct access for retroperitoneal laparoscopy in dogs.

Pattern-triggered immunity (PTI) includes the different transcriptional and physiological responses that enable plants to ward off microbial invasion. Surface-localized pattern-recognition receptors (PRRs) recognize conserved microbe-associated molecular patterns (MAMPs) and initiate a branched signaling cascade that culminate in an effective restriction of pathogen growth. In the model species Arabidopsis thaliana, early PTI events triggered by different PRRs are broadly conserved although thei

Pheochromocytoma should be considered a differential diagnosis for dogs with Cushing's syndrome with an adrenal tumor. A good prognosis can be expected with prompt diagnosis and surgical intervention.

Accurate state-of-health (SoH) prediction of lithium-ion batteries (LiBs) is a critical step in LiBs health prognostics to ensure its reliable operation and safety. Recently, there has been an increase in graph neural network (GNN) adaptation across many fields including LiBs health prognostics, which have shown benefits of spatio-temporal-based neural networks over the traditional counterparts. However, many of these studies have been shown to rely on discharge profiles as part of their input f

The plant defense responses to microbial infection are tightly regulated and integrated with the developmental program for optimal resources allocation. Notably, the defense- associated hormone salicylic acid (SA) acts as a promoter of flowering while several plant pathogens actively target the flowering signaling pathway to promote their virulence or dissemination. <i>Ralstonia pseudosolanacearum</i> inject tens of effectors in the host cells that collectively promote bacterial proliferation in

Received signal strength indication method enables flexible positioning without additional hardware installation and modification from communication resources. The expectation value of distance is changed due to the shadow fading. The effects of shadow fading in indoor RSSI ranging and convergence with pedestrian dead reckoning by using Extended Kalman Filter are presented. The fusion of pedestrian dead reckoning and RSSI ranging simulation shows that the compensation Shadow Fading effect has sl

Since the discovery of klotho as an anti-aging gene, its association with tumors has been studied. Several previous studies have reported the down-expression of klotho in various human cancers, and much of its mechanism has been revealed. Nonetheless, the significance of klotho in canine mammary gland tumors is not yet known. This study aimed to determine whether klotho is expressed within normal canine mammary glands and whether the expression changes in benign and malignant tumors. Using immun

The hormone leptin is produced by mature adipocytes and plays an important role in regulating food intake and energy metabolism through its interaction with the leptin receptor. In addition to roles in obesity and obesity-related diseases, leptin has been reported to affect the components and secretion of bile in leptin-deficient mice. Furthermore, gallbladder diseases such as cholelithiasis are known to be associated with serum leptin concentrations in humans. We hypothesized that the canine ga
