Wound immersed in seawater with high-salt, high sodium, and pathogenic bacteria, especially gram-negative can cause serious infections difficulties wound repair. The present study aimed to prepare a composite hydrogel composed of hyaluronic acid (HA) quaternized chitosan (QCS) which may promote healing seawater-immersed wounds prevent from bacterial infection. Based on the dynamic Schiff base linkage, was prepared by mixing oxidized (OHA) acid-hydrazide (HA-ADH) under physiological...

ABSTRACT OBJECTIVE To gain insight into the magnitude of problem chronic skin wounds in a hospital northern China. METHODS Researchers conducted retrospective analysis electronic health records cases and controls, including 1,977 patients with admitted to hospital’s medical wards over 5 years. Multiple logistic regression was used establish factors correlating development wounds. RESULTS The total prevalence increased study period, occurrence these significantly correlated male sex, married...

Abstract Microalgae‐bacteria systems present a promising approach for CO 2 reduction in wastewater treatment. The effect of inoculation bacteria‐algae ratio on performance was investigated this study. Different ratios (bacteria: algae 1:2, 1:1, 1:0.5, 1:0.25, 1:0.125, w/w) obtained comparable nutrients removal (p > 0.05). Over time, the converged into two groups (3:1 and 4:1), demonstrating self‐adaption between bacteria microalgae. Furthermore, principal component analysis (PCA)...

BACKGROUND:Worldwide, the treatment of complications associated with type 2 diabetes mellitus, including diabetic foot ulcer (DFU), results in an economic burden for patients and healthcare systems. This study aimed to use high-throughput 16S rRNA gene sequencing investigate changes skin microbiome mellitus from a single center China. MATERIAL AND METHODS:Fifty-two participants were divided into 4 groups: healthy controls (n=13); short-term (<2 years; n=13); intermediate-term (5–8 long-term...

A rapid wound healing is beneficial for not only recovering aesthetics but also reducing pain, complications and healthcare burdens. Acellular dermal matrix (ADM) paste has been used to repair burn wounds shown promote angiogenesis as well fibroblast attachment migration. However, its efficacy still needs be significantly improved meet clinical demands. To approach this problem, we adopted a human salivary peptide — Histatin 1 (Hst1). Hst1 was chosen because of potency the adhesion,...

Abstract To address whether the addition of intensity-modulated radiotherapy (IMRT) compared to three-dimensional conformal (3D-CRT) aggravate radiation-induced acute injury locoregionally advanced nasopharyngeal carcinoma (LANPC) patients with induction chemotherapy (IC) followed by concurrent chemoradiotherapy (CCRT). We conducted a prospective study 182 in stage III IVb biopsy-proven nonmetastatic LANPC who newly underwent and sequentially received IC, CCRT at our institution. Occurring...

Radiation-induced skin injuries such as lesions (RSLs) and dermatitis are the most common complication during radiotherapy (RT) for nasopharyngeal carcinoma, but little is known about risk factors unique to oncology. This study sought a greater understanding of these stratify patients based on guide clinical decision-making.Investigators analyzed data 864 consecutive referred RT center Southern Theater General Hospital new RSL from 2013 2019. These were followed up an average approximately...

Abstract Background Acute skin wounds may compromise the barrier, posing a risk of infection. Small intestinal submucosa (SIS) is widely used to treat acute and chronic wounds. However, efficacy SIS accelerate wound healing still needs be improved meet clinical demands. To tackle this problem, platelet-rich plasma (PRP) due its potency promote proliferation, migration adhesion target cells. In study, we applied PRP explore their effects on by evaluating re-epithelialization, collagen...

It has been reported that the beta-adrenergic receptor blocker (propranolol) and a-adrenergic (AR) (phentolamine) both can inhibit human endothelial cell (EC) angiogenesis in vitro. However, it is unknown whether this inhibition also acts on pericytes. The present study aimed to determine how pericytes react treatment with an a-/β- AR blocker. In study, proliferation assays scratch assay were performed assess effect of phentolamine or propranolol migration. Western blot ELISA employed...

Objective: To analyze the clinical characteristics of 801 inpatients with chronic wounds. Methods: The medical records patients wounds who were admitted to General Hospital Southern Theater Command PLA (hereinafter referred as author's unit) from January 2013 December 2017, including gender, occupation, wound type, age, department distribution, recovery status, time, hospitalization cost, treatment method, outcome, and expenses retrospectively analyzed. Data statistically analyzed chi-square...

ABSTRACT BACKGROUND Rapid estimation of the area chronic wounds is clinically important. A simple method using thumb was investigated for universal physical measurement, particularly small and multiple wounds; surface (TSA) then compared with total body (TBSA). METHODS cross-sectional observational study random sampling were used to obtain characteristics 343 participants. Data related handprint palm collected a scanner laptop assessed image software. The TSA as percentage TBSA confirmed...

This paper presents our research on implementing SGM to obtain reliable edge points from intensity indoor image pair. To this end, the most basic theory of is first outlined and with concern inherent nature points, facts that take much advantage features are summarized as well. Next, we make discussion detail procedures matching simplified algorithm, in which gradient magnitude images used compute mutual information match cost costs detected aggregated. Finally, result presented technique...

In this study, we propose a finite-difference (FD) algorithm for calculating the seismoelectric logging in horizontally-stratified fluid-saturated porous formation and/or with mud cake neighbouring borehole. Without considering negligible feedback influence of seismic-wave-induced electric field, seismic waves borehole, cake, and are calculated by identical FD discrete formula fluid, solid media. And then distribution induced potential is at each time known field as source field.

Abstract Background: Induction chemotherapy (IC) combined with concurrent chemoradiotherapy (CCRT) was the new standard treatment for nasopharyngeal carcinoma (NPC). We aimed to address whether addition of intensity-modulated radiotherapy (IMRT) compared three-dimensional conformal (3D-CRT) aggravate radiation-induced acute injury these patients. Methods: conducted a prospective study consecutive patients biopsy-proven nonmetastatic NPC who newly underwent and sequentially received IC,...
