High-Efficiency DC-DC Converter for Large Input-Voltage Fluctuations in Solar Applications

引用

Chinese Journal of Electronics 2015年第3期24卷 502-507页

作者： AGUILLON-GARCIA jacobo BANUELOS-SANCHEZ Pedro SIST Sun Yat-sen University

In the solar energy systems the solar irradiance variation is partially engaged, limiting the converter’s transformation rate for a certain input amount and leaving the rest of energy unconverted. In order to utilize at its maximum the energy provided from a Photovoltaic(PVP) system, this manuscript proposed a topology that can cope with marginal input voltage variations from 60V(DC) up to 1050V(DC) for a steady output voltage of 700V(DC). This output voltage value is suitable for any interlink post-regulation architecture. Based on previous observations, this paper presents a wide-input voltage high-efficiency non-isolated single-control topology. Analysis, operating stages, simulations and experimental results for a 3k W prototype are presented.

Stem cell therapy for faecal incontinence: Current state and future perspectives

World Journal of Stem Cells 2018年第7期10卷 82-105页

Faecal continence is a complex function involving different organs and systems. Faecal incontinence is a common disorder with different pathogeneses, disabling consequences and high repercussions for quality of life. Current management modalities are not ideal, and the development of new treatments is needed. Since 2008, stem cell therapies have been validated, 36 publications have appeared(29 in preclinical models and seven in clinical settings), and six registered clinical trials are currently ongoing. Some publications have combined stem cells with bioengineering technologies. The aim of this review is to identify and summarise the existing published knowledge of stem cell utilization as a treatment for faecal incontinence. A narrative or descriptive review is presented. Preclinical studies have demonstrated that cellular therapy, mainly in the form of local injections of muscle-derived(muscle derived stem cells or myoblasts derived from them) or mesenchymal(bone-marrow-or adipose-derived) stem cells, is safe. Cellular therapy has also been shown to stimulate the repair of both acute and subacute anal sphincter injuries, and some encouraging functional results have been obtained. Stem cells combined with normal cells on bioengineered scaffolds have achieved the successful creation and implantation of intrinsically-innervated anal sphincter constructs. The clinical evidence, based on adipose-derived stem cells and myoblasts, is extremely limited yet has yielded some promising results, and appears to be safe. Further investigation in both animal models and clinical settings is necessary to drawing conclusions. Nevertheless, if the preliminary results are confirmed, stem cell therapy for faecal incontinence may well become a clinical reality in the near future.

AIM To evaluate the efficacy of antimicrobial susceptibilityguided therapy before first-line treatment for infection in patients with dual or triple antibiotic *** A total of 1034 patients infected by Helicobacter pylori(H. pylori) during 2013-2014 were tested for antimicrobial susceptibility. 157 of 1034(15%) patients showed resistance to two(127/1034; 12%) and to three(30/1034; 3%) antibiotics. Sixty-eight patients with dual H. pylori-resistance(clarithromycin, metronidazole or levofloxacin) were treated for 10 d with triple therapies: OAL(omeprazole 20 mg b.i.d., amoxicillin 1 g b.i.d., and levofloxacin 500 mg b.i.d.) 43cases, OAM(omeprazole 20 mg b.i.d., amoxicillin 1 g b.i.d., and metronidazole 500 mg b.i.d.) 12 cases and OAC(omeprazole 20 mg ***., amoxicillin 1 g b.i.d., and clarithromycin 500 mg b.i.d.) 13 cases based on the antimicrobial susceptibility testing. Twelve patients showed triple H. pylori-resistance(clarithromycin, metronidazole and levofloxacin) and received for 10 d triple therapy with OAR(omeprazole 20 mg ***., amoxicillin 1 g b.i.d., and rifabutin 150 mg b.i.d.). Eradication was confirmed by 13C-urea breath test. Adverse effects and compliance were assessed by a questionnaire. RESULTS Intention-to-treat eradication rates were: OAL(97.6%), OAM(91.6%), OAC(92.3%) and OAR(58.3%). Cure rate was significantly higher in na?ve patients treated with OAR-10 compared to patients who had two or three previous treatment failures(83% vs 33%). Adverse events rates for OAL, OAM, OAC and OAR were 22%, 25%, 23% and 17%, respectively, all of them mild-moderate. CONCLUSION Antimicrobial susceptibility-guided triple therapies during 10 d for first-line treatment leads to an eradication rate superior to 90% in patients with dual antibiotic H. pylori resistance.
