Background and aims: Although rehabilitation of the partially dentate jaw with implant-supported fixed prosthesis has achieved high success rates, little is known regarding their effects on the opposing natural dentition. The periodontal ligament (PDL) functions as a dynamic attachment apparatus, and responds to occlusal forces by widening/narrowing and alterations in collagen fiber density/ or...

The blocking of programmed death ligand-1 (PDL-1) has been shown to enhance virus-specific CD8 T cell function during chronic viral infections. Though, how PDL-1 blocking at the time of priming affects the quality of CD8 T cell response to acute infections is not well understood and remains controversial. This report demonstrates that the magnitude of the primary and secondary CD8 T cell respon...

introduction: pulsed dye laser (pdl) is an important treatment for superficial infantile hemangioma, but few studies report on its cellular mechanism. the aim of this study was to evaluate alterations of serum vascular endothelial growth factor (vegf) level in infantile hemangioma (ih) patients after laser treatment and effects of pdl irradiation on human umbilical vein endothelial cells (huvec...

Abstract The outbreak of novel coronavirus pneumonia (COVID-19), defined as a worldwide pandemic, has been public health emergency international concern. Pudilanxiaoyan oral liquid (PDL), an effective drug Traditional Chinese Medicine (TCM), is considered to be and alternative means for clinical prevention COVID-19. purpose this study was identify potential active constituents PDL, explore its ...

Abstract: Three-resonator wireless power transfer (WPT) systems have been proposed to improve the power transfer efficiency (PTE) and power delivered to the load (PDL) in recent years. However, analysis formulas of a three-resonator WPT system are complicated, and the parameters for clarifying the transfer characteristics of this system are difficult to extract. In this paper, concise formulas ...

Resolution agonists are endogenous mediators that drive inflammation to homeostasis. We earlier demonstrated in vivo activity of resolvins and lipoxins on regenerative periodontal wound healing. The goal of this study was to determine the impact of resolvin D1 (RvD1) on the function of human periodontal ligament (PDL) fibroblasts, which are critical for wound healing during regeneration of the ...

Background. Basal cell carcinoma (BCC) is the most prevalent skin cancer. Because of its highly vascular characteristic, it is amendable to treatment with pulse dye laser (PDL). The goal of this study is to determine the safety and efficacy of PDL therapy for mostly facial BCCs. Materials and Methods. Sixteen men and thirteen women (29 total) with 39 biopsy-proven BCCs were treated with 1-4 PDL...

Propositional Dynamic Logic (PDL) of [FL] defines meaning of programs in terms of binary input-output relations. Basic regular operations on programs are interpreted as superposition, union, and reflexive-transitive closure of relations. The intersection, cf. [HI , is a binary program forming functor a~b with the meaning given by the set-theoretical intersection of relations corresponding to pr...

A mutation of UNCL, an inner nuclear membrane RNAbinding protein, has been found to eliminate mechanotransduction in Drosophila. UNCL is expressed in human periodontal tissue including in periodontal ligament (PDL) fibroblasts. However, it is unclear how a mechanical stimulus is translated into cellular responses in PDL fibroblasts. The aim of this study was to evaluate the effect of UNCl on me...

In long haul networks, the random birefringence induced in the optical fiber leads to a considerable Polarization Mode Dispersion (PMD). Polarization Dependent Loss (PDL) mainly occurs in optical components and depends on the state of polarization of optical signals. The presence of PMD and PDL causes pulsewidth narrowing and the pulsewidth reduction depends on states of polarization at which t...
