Neauvia hydrogel (N-Gel) is a hyaluronic acid-based dermal filler, cross-linked with polyethylene glycol. This filler contains sodium hyaluronate at different concentrations, is poly (ethylene glycol) diglycidyl ether cross-linked, the hydrogel contains also glycine and l-prolyne. Assessing any effects of N-Gel on immunity and inflammation is of crucial importance. The aim of the study was to characterize the ability of N-Gel to modulate human polymorphonuclear leukocyte (PMN) functions, including migration, oxidative metabolism and production of proinflammatory mediators. N-Gel was tested on isolated human PMN. Spontaneous and N-formylmethionyl-leucyl-phenylalanine (fLMP)-stimulated migration were examined using the Boyden Chamber technique, while the oxidative metabolism was assessed through spectrofluorometric measurement of reactive oxygen species (ROS) production under resting conditions and after stimulation with fLMP. Tumor necrosis factor (TNF)-α and interleukin (IL)-8 mRNA levels were measured by real-time PCR after stimulation with fMLP or E. coli lipopolysaccharide (LPS). This study showed that N-Gel reduced fMLP-induced migration and ROS production without affecting these functions in resting cells. In addition, incubation of PMN with N-Gel effectively reduced both TNF-α and IL-8 mRNA levels. N-Gel modulates critical functions of human PMN such as migration and oxidative metabolism, indicating its potential as an anti-inflammatory agent. This article is protected by copyright.

A sample of 1,074 participants between 10-17years was recruited. Body size dissatisfaction was assessed by silhouettes scale. Dietary pattern, physical activity, and socioeconomic status were assessed by questionnaires. Body mass index was objectively measured. Body size dissatisfaction prevalence was 77.0%, where 29.8% desired to increase body size and 47.2% desired to decrease body size. Adolescents who desired to increase body size were more likely to consume vegetables and sweets, and less likely to be in highest quartile of physical activity than satisfied adolescents. Those adolescents who desired to reduce body size were more likely to have low fruit consumption and low vegetables consumption than satisfied adolescents. Health actions aiming to reduce body dissatisfaction in adolescents should address the improvement of dietary pattern and physical activity engagement, considering the desire to increase or to decrease body size, once were differently associated in this study.

MATERIALS AND METHODS SPTFL (Urolase SP, IRE-Polus, Fryazino, Russia) with an emission wavelength of 1.94 μm and a HoYAG laser (P120H, Lumenis, Yokneam, Israel) with Moses technology were compared. Pulse shape, stone retropulsion, and ablation efficiency were evaluated using Begostones and compared for each laser modality short (SP), long (LP), and Moses pulse (MP) for HoYAG, regular pulse (RP) and dual pulse (DP) for SPTFL. RESULTS HoYAG SP mode exhibited an asymmetrical pulse shape with steep leading slope and much more gradual trailing slope, without any flat section. Pulses generated by SPTFL were significantly longer and therefore had lower peak power (Ppeak) than those generated by HoYAG laser at equivalent energy settings. Retropulsion for HoYAG LP and MP modes was similar and lower than that of SP, but higher than for SPTFL (all p ≤0.02), with an average stone displacement about 4 times and 2 times lower for SPTFL as compared to HoYAG. Comparison of ablation volumes indicated that SPTFL induced significantly higher (2-fold) ablation than HoYAG laser. CONCLUSIONS Magnitude and initial velocity of stone retropulsion decrease with longer pulse duration and lower pulse peak power, but without sacrificing ablation efficiency. These observations are manifest when comparing HoYAG laser with SPTFL. The novel SPTFL provides greater versatility and control of pulse parameters than HoYAG laser. Further clinical investigation of practical benefits achievable with pulse-shaping SPTFL modes is warranted. This article is protected by copyright.

Reporting two cases with acute cerebral infarction after RFA for AF. Two patients were both with AF, and intracardiac thrombus was excluded through transesophageal echocardiogram (TEE) before procedure. Approach of ablation circumferential pulmonary vein ablation in left atrium to isolate pulmonary vein plus linear ablation in the top and bottom of left atrium (BOX procedure). They both received Dabigatran Etexilate 110 mg twice daily, starting 6 hr after ablation. Symptoms of major stroke appeared 30 hr after ablation in Case 1. Occlusion was detected in M1 segment of the left middle cerebral artery by MRI 2 hr after symptoms onset. Intravenous thrombolysis was given immediately. Selleckchem β-Sitosterol In Case 2, the patient presented symptoms of major stroke 34 hr after ablation and occlusion in the basilar artery was confirmed by MRI 4.5 hr after symptoms onset. Although it was beyond the thrombolysis time window, mechanical thrombectomy was taken 7 hr after the symptoms onset. The culprit artery was successfully revascularized in both cases. In Case 1, NIHSS score was reduced from 8 (before thrombolysis) to 0 (24 hr after thrombolysis). In Case 2, NIHSS score decreased from 18 (before embolectomy) to 3 (24 hr after embolectomy). Both of the patients live a normal life without brain function impairment and hemorrhage until the last follow-up. Timely recanalization could attained a good cure effect when acute stoke was happened after RFA for AF. © 2020 The Authors. Annals of Noninvasive Electrocardiology published by Wiley Periodicals, Inc.
