The mean percentage of anterior/posterior/all teeth with severe wear were 42.3 ± 28.1, 14.5 ± 19.9 and 30.0 ± 21.7. Anterior teeth, particularly the incisal surface of central incisors were most affected. Prexasertib mw The mean flow-rate of SWS and SPS were 0.1 ± 0.1 ml/min and 0.03 ± 0.07 ml/min respectively. Thirty (44.1 percent) and 48 (70.6 percent) participants were found to have low/no buffering capacity of SWS and SPS respectively. Multiple-regression analyses revealed the SWS flow-rate was associated with the percentage of anterior teeth with severe wear (p=0.03). CONCLUSION Anterior tooth wear is a significant dental problem among NPC survivors and was associated with hypo-salivation. CLINICAL SIGNIFICANCE Patients with hypo-salivation should be being monitored for tooth wear particularly on the anterior teeth. INTRODUCTION Resuscitative endovascular balloon occlusion of the aorta (REBOA) in zone I increases systemic blood pressure during cardiopulmonary resuscitation (CPR), while also obstructing the blood flow to distal organs. The aim of the study was to compare the effects on systemic blood pressure and visceral blood flow of REBOA-III (zone III, infrarenal) and REBOA-I (zone I, supraceliac) during non-traumatic cardiac arrest and CPR. METHODS Cardiac arrest was induced in 61 anesthetized pigs. Thirty-two pigs were allocated to a hemodynamic study group where the primary outcomes were systemic arterial pressures and 29 pigs were allocated to a blood flow study group where the primary outcomes were superior mesenteric arterial (SMA) and internal carotid arterial (ICA) blood flow. After 7-8minutes of CPR with a mechanical compression device, REBOA-I, REBOA-III or no aortic occlusion (control group) were initiated after randomization. RESULTS Systemic mean and diastolic arterial pressures were statistically higher during CPR with REBOA-I compared to REBOA-III (50mmHg and 16mmHg in REBOA-I vs 38mmHg and 1mmHg in REBOA-III). Systemic systolic, mean and diastolic arterial pressures were statistically elevated during CPR in the REBOA-I group compared to the controls. The SMA blood flow increased by 49% in REBOA-III but dropped to the levels of the controls within minutes. The ICA blood flow increased the most in REBOA-I compared to REBOA-III and the control group (54%, 19% and 0%, respectively). CONCLUSION In experimental non-traumatic cardiac arrest and CPR, REBOA-I increased systemic blood pressures more than REBOA-III, and the potential enhancement of visceral organ blood flow by REBOA-III was short-lived. V.This review analyses physical drug delivery enhancement technologies with a focus on improving UV damaged skin, actinic keratoses and non-melanoma skin cancer treatment. In recent years, physical drug delivery enhancement has been shown to enhance cosmeceutical and skin cancer treatment efficacy, but there are pros and cons to each approach which we discuss in detail. Mechanisms of action, clinical efficacy, experimental design, outcomes in academic publications, clinical trial reports and patents are explored to evaluate each technology with a critical, translation focused lens. We conclude that the commercial success of cosmeceutical applications, e.g. microneedles, will drive further innovation in this arena that will impact how actinic keratoses and non-melanoma skin cancers are clinically managed. V.Spiders produce diverse silk fibers with distinct properties for daily survival. Among these silk fibers, dragline silk spun by major ampullate gland is used for bridgelines and web radii, exhibiting both outstanding tensile strength and extensibility. Although more and more full-length major ampullate spidroin gene sequences have been reported, the research regarding alternative splicing events of spidroins are rare. Here we describe two spliceoforms of major ampullate spidroin 1 (MaSp1) from Araneus ventricosus, and both of them are lack of central repetitive region. The minor isoform only has terminal regions. For the major isoform, however, the N-linker and terminal regions are all retained. Furthermore, we investigated the functions of N-linker structure of A. ventricosus MaSp1, based on the properties of the two spliceoforms. The dimer level of major isoform (MaSp1-2) is higher than that of the minor isoform (MaSp1-1). Moreover, the MaSp1-2 protein display higher melting temperature (Tm) than MaSp1-1, and the MaSp1-2 fibers exhibit higher tensile strength than MaSp1-1 fibers. These studies demonstrate that the N-linker region promotes the formation of intermolecular disulphide bond, suggesting a strategy to enhance the thermostabilization and mechanical properties of spidroins. Three-dimensional (3D) porous films based on chitosan/pectin/ZnO nanoparticles (NPs) were prepared for wound healing by the freeze-drying method. The chemical nature, composition and morphology of these films were revealed by FTIR, XRD, EDX, SEM and BET analysis. SEM micrographs showed a decrease in the pore size and porosity of chitosan/pectin/ZnO films when increasing the content of ZnO NPs. The developed films presented the swelling degree and water retention ability in the range of 189-465 and 230-390%, respectively. Moreover, they showed an improved compression strength and controlled degradation in the lysozyme-containing medium in comparison with control. MTT assay demonstrated the biocompatibility of chitosan/pectin/ZnO films against the primary human dermal fibroblast cells (HFCs). Among the developed chitosan/pectin/ZnO films, CPZnO-2 films presented the increased rate of cell proliferation and migration. Also, they exhibited antimicrobial activity against the gram-positive and gram-negative bacteria and fungi. These results suggested that chitosan/pectin/ZnO films could be safe, convenient and effective for wound healing. V.In this study, a novel thiourea grafted porous sodium alginate-based adsorbent was synthesized by combining ion-imprinting and direct templating method. Due to ion-imprinting, the prepared adsorbent has demonstrated outstanding selectivity towards Pd (II) from bi-metallic solution at different pH values. Langmuir and both pseudo-first and pseudo-second kinetic equations were used to describe the adsorption isotherm and kinetics, respectively. FT-IR, XPS, and SEM-EDX analyses suggested that selective adsorption of Pd (II) was dominated by electrostatic interactions at pH 1.0 and chelation on imprinted sorption sites at pH 3.0. Density functional theory (DFT) calculation further explained the effect of ion-imprinting and provided two binding configurations, which is consistent with characterization analyses. The pregnant adsorbent can be regenerated and reused by thiourea solution in dilute hydrochloric acid. Therefore, the synthesized adsorbent would be useful as a selective adsorbent for the enrichment of Pd (II) from effluents.
