It examines the effects on their physiological and psychological responses and overall satisfaction with nursing care. Methods: A total of 84 patients scheduled for laparoscopic cholecystectomy were selected through convenient sampling and randomly assigned to either the control group or the intervention group using a random number table. Each group consisted of 42 patients. The control group received standard surgical nursing care. In addition to standard care, the intervention group received handshake and information support from the circulating nurse before anesthesia induction. Vital signs were recorded before surgery and before anesthesia induction. Anxiety levels were measured using the State-Trait Anxiety Inventory (STAI) and the State-Anxiety Inventory (S-AI), while nursing satisfaction was assessed using a numerical rating scale. Results: No significant differences were found between the two groups in systolic and diastolic blood pressures before surgery and anesthesia induction (P > 0.05). However, there was a significant difference in heart rate before anesthesia induction (P Conclusion: Providing handshake and information support before anesthesia induction effectively reduces stress, alleviates anxiety, and enhances comfort and satisfaction among patients undergoing laparoscopic cholecystectomy.展开更多

文摘Flowering is one of the most important phenological periods,as it determines the timing of fruit maturation and seed dispersal.To date,both nitric oxide(NO)and DNA demethylation have been reported to regulate flowering in plants.However,there is no compelling experimental evidence for a relationship between NO and DNA demethylation during plant flowering.In this study,an NO donor and a DNA methylation inhibitor were used to investigate the involvement of DNA demethylation in NO-mediated tomato(Solanum lycopersicum cv.Micro-Tom)flowering.The results showed that the promoting effect of NO on tomato flowering was dose-dependent,with the greatest positive effect observed at 10μmol L^(-1) of the NO donor S-nitrosoglutathione(GSNO).Treatment with 50μmol L^(-1) of the DNA methylation inhibitor 5-azacitidine(5-AzaC)also significantly promoted tomato flowering.Moreover,GSNO and 5-AzaC increased the peroxidase(POD)and catalase(CAT)activities and cytokinin(CTK)and proline contents,while they reduced the gibberellic acid(GA3)and indole-3-acetic acid(IAA)contents.Co-treatment with GSNO and 5-AzaC accelerated the positive effects of GSNO and 5-AzaC in promoting tomato flowering.Meanwhile,compared with a GSNO or 5-AzaC treatment alone,co-treatment with GSNO+5-AzaC significantly increased the global DNA demethylation levels in different tissues of tomato.The results also indicate that DNA demethylation may be involved in NO-induced flowering.The expression of flowering genes was significantly altered by the GSNO+5-AzaC treatment.Five of these flowering induction genes,ARGONAUTE 4(AGO4A),SlSP3D/SINGLE FLOWER TRUSS(SFT),MutS HOMOLOG 1(MSH1),ZINC FINGER PROTEIN 2(ZFP2),and FLOWERING LOCUS D(FLD),were selected as candidate genes for further study.An McrBC-PCR analysis showed that DNA demethylation of the SFT gene in the apex and the FLD gene in the stem might be involved in NO-induced flowering.Therefore,this study shows that NO might promote tomato flowering by mediating the DNA demethylation of flowering induction genes,and it provides direct evidence for a synergistic effect of NO and DNA demethylation in promoting tomato flowering.

文摘Structural regulation of Pd-based electrocatalytic hydrodechlorination(EHDC)catalyst for constructing high-efficient cathode materials with low noble metal content and high atom utilization is crucial but still challenging.Herein,a support electron inductive effect of Pd-Mn/Ni foam catalyst was proposed via in-situ Mn doping to optimize the electronic structure of the Ni foam(NF),which can inductive regulation of Pd for improving the EHDC performance.The mass activity and current efficiency of Pd-Mn/NF catalyst are 2.91 and 1.34 times superior to that of Pd/NF with 2,4-dichlorophenol as model compound,respectively.The Mn-doped interlayer optimized the electronic structure of Pd by bringing the d-state closer to the Fermi level than Pd on the NF surface,which optimizied the binding of EHDC intermediates.Additionally,the Mn-doped interlayer acted as a promoter for generating H∗and accelerating the EHDC reaction.This work presents a simple and effective regulation strategy for constructing high-efficient cathode catalyst for the EHDC of chlorinated organic compounds.

文摘The hyperloop idea,which is one of the most ecofriendly,low-carbon emissions,and fossil fuel-efficient modes of transportation,has recently become quite popular.In this study,a double-sided linear induction motor(LIM)with 500 W of output power,60 N of thrust force and 200 V/38.58 Hz of supply voltage was designed to be used in hyperloop development competition hosted by the scientific and technological research council of turkey(TüB?TAK)rail transportation technologies institute(RUTE).In contrast to the studies in the literature,concentrated winding is preferred instead of distributed winding due to mechanical constraints.The electromagnetic design of LIM,whose mechanical and electrical requirements were determined considering the hyperloop development competition,was carried out by following certain steps.Then,the designed model was simulated and analyzed by finite element method(FEM),and the necessary optimizations have been performed to improve the motor characteristics.By examining the final model,the applicability of the concentrated winding type LIM for hyperloop technology has been investigated.Besides,the effects of primary material,railway material,and mechanical air-gap length on LIM performance were also investigated.In the practical phase of the study,the designed LIM has been prototyped and tested.The validation of the experimental results was achieved through good agreement with the finite element analysis results.

文摘Electrical energy can be harvested from the rotational kinetic energy of moving bodies,consisting of both mechanical and kinetic energy as a potential power source through electromagnetic induction,similar to wind energy applications.In industries,rotational bodies are commonly present in operations,yet this kinetic energy remains untapped.This research explores the energy generation characteristics of two rotational body types,disk-shaped and cylinder-shaped under specific experimental setups.The hardware setup included a direct current(DC)motor driver,power supply,DC generator,mechanical support,and load resistance,while the software setup involved automation testing tools and data logging.Electromagnetic induction was used to harvest energy,and experiments were conducted at room temperature(25℃)with controlled variables like speed and friction.Results showed the disk-shaped body exhibited higher energy efficiency than the cylinder-shaped body,largely due to lower mechanical losses.The disk required only two bearings,while the cylinder required four,resulting in lower bearing losses for the disk.Additionally,the disk experienced only air friction,whereas the cylinder encountered friction from a soft,uneven rubber material,increasing surface contact losses.Under a 40 W resistive load,the disk demonstrated a 17.1%energy loss due to mechanical friction,achieving up to 15.55 J of recycled energy.Conversely,the cylinder body experienced a 48.05%energy loss,delivering only 51.95%of energy to the load.These insights suggest significant potential for designing efficient energy recycling systems in industrial settings,particularly in manufacturing and processing industries where rotational machinery is prevalent.Despite its lower energy density,this system could be beneficially integrated with energy storage solutions,enhancing sustainability in industrial practices.
文摘As one of the most important industrially viable methods for carbon dioxide(CO_(2))utilization,methanol synthesis serves as a platform for production of green fuels and commodity chemicals.For sustainable methanol synthesis,In_(2)O_(3)is an ideal catalyst and has garnered significant attention.Herein,cubic In_(2)O_(3)nanoparticles were prepared via the precipitation method and evaluated for CO_(2)hydrogenation to produce methanol.During the initial 10 h of reaction,CO_(2)conversion gradually increased,accompanied by a slow decrease of methanol selectivity,and the reaction reached equilibrium after 10-20 h on stream.This activation and induction stage may be attributed to the sintering of In_(2)O_(3)nanoparticles and the creation of more oxygen vacancies on In_(2)O_(3)surfaces.Further experimental studies demonstrate that hydrogen induction created additional oxygen vacancies during the catalyst activation stage,enhancing the performance of In_(2)O_(3)catalyst for CO_(2)hydrogenation.Density functional theory calculations and microkinetic simulations further demonstrated that surfaces with higher oxygen vacancy coverages or hydroxylated surfaces formed during this induction period can enhance the reaction rate and increase the CO_(2)conversion.However,they predominantly promote the formation of CO instead of methanol,leading to reduced methanol selectivity.These predictions align well with the above-mentioned experimental observations.Our work thus provides an in-depth analysis of the induction stage of the CO_(2)hydrogenation process on In_(2)O_(3)nano-catalyst,and offers valuable insights for significantly improving the CO_(2)reactivity of In_(2)O_(3)-based catalysts while maintaining long-term stability.
文摘BACKGROUND The induced-membrane technique was initially described by Masquelet as an effective treatment for large bone defects,especially those caused by infection.Here,we report a case of chronic osteomyelitis of the radius associated with a 9 cm bone defect,which was filled with a large allogeneic cortical bone graft from a bone bank.Complete bony union was achieved after 14 months of follow-up.Previous studies have used autogenous bone as the primary bone source for the Masquelet technique;in our case,the exclusive use of allografts is as successful as the use of autologous bone grafts.With the advent of bone banks,it is possible to obtain an unlimited amount of allograft,and the Masquelet technique may be further improved based on this new way of bone grafting.CASE SUMMARY In this study,we reported a case of repair of a long bone defect in a 40-year-old male patient,which was characterized by the utilization of allograft cortical bone combined with the Masquelet technique for the treatment of the patient's long bone defect in the forearm.The patient's results of functional recovery of the forearm were surprising,which further deepens the scope of application of Masquelet technique and helps to strengthen the efficacy of Masquelet technique in the treatment of long bones indeed.CONCLUSION Allograft cortical bone combined with the Masquelet technique provides a new method of treatment to large bone defect.

文摘To improve the efficiency of ship traffic in frequently traded sea areas and respond to the national“dual-carbon”strategy,a multi-objective ship route induction model is proposed.Considering the energy-saving and environmental issues of ships,this study aims to improve the transportation efficiency of ships by providing a ship route induction method.Ship data from a certain bay during a defined period are collected,and an improved backpropagation neural network algorithm is used to forecast ship traffic.On the basis of the forecasted data and ship route induction objectives,dynamic programming of ship routes is performed.Experimental results show that the routes planned using this induction method reduce the combined cost by 17.55%compared with statically induced routes.This method has promising engineering applications in improving ship navigation efficiency,promoting energy conservation,and reducing emissions.
文摘BACKGROUND Tofacitinib is an oral,selective Janus kinase inhibitor that is approved for the treatment of ulcerative colitis(UC).The 8-week induction protocol involves the administration of 10 mg twice daily(bid)with the possibility of extending the induction period to 16 weeks.The maintenance dose of tofacitinib is either 5 mg or 10 mg bid.AIM To assess predictors for clinical remission and drug persistence in patients with UC receiving the extended induction tofacitinib protocol.METHODS This was a real-world multicenter retrospective study in patients with moderateto-severe UC.Patients received physician-directed extended induction tofacitinib treatment.We collected clinical and demographic data at baseline and data regarding clinical,laboratory,and endoscopic evaluations,therapeutic modifications,and adverse events at the 52-week follow-up.Possible predictors for clinical remission at week 52 was the primary endpoint.Differences between patients receiving 5 mg bid vs 10 mg bid at week 52 and identification of predictors for treatment persistence were secondary endpoints.RESULTS Thirty-seven consecutive patients from 11 medical centers were included[51.4%males with median age 39(17-64)years].Twenty-eight patients continued treatment until week 52(75.7%)with 67.9%receiving 10 mg tofacitinib;all had prior history of biologic use.We observed that 57.1%of patients achieved clinical remission(66.7%in the 5 mg tofacitinib group and 52.6%in the 10 mg tofacitinib group,P=0.483).De-escalation to 5 mg tofacitinib was attempted in 17 patients with a success rate of 52.9%.Prior biologic use was significantly more frequent in patients treated with 10 mg tofacitinib.Active smoking was significantly associated with treatment discontinuation at week 52.We identified eight adverse events,and only one led to treatment discontinuation.CONCLUSION Our results supported the extended induction strategy with tofacitinib in selected patients with UC.Patients with prior failure of advanced therapies particularly benefitted,highlighting the importance of personalized maintenance regimens.
文摘BACKGROUND Oral 5-aminosalicylic acid(5-ASA)has been a cornerstone treatment for mild to moderate ulcerative colitis(UC),traditionally used to maintain remission.With the rise of advanced therapies(biologics and small molecules),the role of 5-ASA has come under renewed scrutiny.While earlier systematic reviews affirmed its efficacy compared to placebo,these did not account for the advent of advanced therapies.AIM To assess the efficacy and safety of oral 5-ASA in maintaining remission in quiescent UC,compared to placebo,alternative 5-ASA formulations,and advanced therapies,in the era of biologics and small molecules.METHODS It was systematically searched MEDLINE,EMBASE,and the Cochrane Library,alongside conference proceedings(European Crohn’s and Colitis Organisation,British Society of Gastroenterology),for randomized controlled trials published between 2003 and 2024 in English.Eligible studies involved oral 5-ASA therapies for quiescent UC with a minimum treatment duration of six months.Outcomes included failure to maintain remission,adverse events,and serious adverse events(SAEs).Data were analyzed using Cochrane methods,with GRADE assessing evidence certainty.RESULTS From 44 studies(9967 participants),5-ASA was superior to placebo in maintaining remission,with 37%of 5-ASA users relapsing at 6-12 months compared to 55%of placebo users[risk ratios(RR):0.68;95%CI:0.61-0.76;high-certainty evidence].SAEs were rare and comparable between groups(RR:0.60;95%CI:0.19-1.84;low-certainty evidence).Comparative analyses suggested 5-ASA remains a viable option alongside advanced therapies,with notable differences in cost and safety profiles.CONCLUSION 5-ASA remains effective and safe for maintaining remission in quiescent UC,even in the advanced therapy era.However,tailored approaches are needed to balance efficacy,safety,and cost in clinical practice.This study provides critical insights to guide therapeutic strategies and underscores the enduring relevance of 5-ASA.

文摘The investigation of reaction kinetics is the key to understanding the nature of reaction processes.However,monitoring fast photochemical reactions by mass spectrometry remains challenging.Herein,we developed an optical focusing inductive electrospray(OF-iESI)mass spectrometry platform for real-time and in-situ photoreaction monitoring.Coaxial irradiation from back of nanoelectrospray emitter with a taper section was utilized,so the emitter could act as optical lens to help achieving much larger optical power density at emitter tip compared to other sections,which allowed for in-situ reaction monitoring of photoreactions.Through theoretical calculations,the highest optical power density region volume was ca.45 nL.We also integrated a controller for the laser source(450 nm),enabling the modulation of pulse duration(>1 ms).This facilitates the study of photochemical reaction kinetics.The in-situ capability of this device was proved by capturing the short-lived photogenerated intermediates during the dehydrogenation of tetrahydroquinoline.This device was further used to investigate the kinetics of triplet energy transfer based Paternò-Büchi reaction.The reaction order has hitherto remained undetermined while the result of OF-iESI suggested it followed pseudo-second-order reaction kinetics.The short-lived donor-acceptor collision complex intermediate was also successfully identified by tandem mass spectrometry.

文摘Superconducting kinetic inductance detectors(KIDs)are considered to be a highly promising technique for the large-scale imaging of millimeter and submillimeter waves in astronomy.As the pixel density and the array size increase,the electromagnetic crosstalk inevitably becomes a problem that prevents increasing the multiplexing during the development of larger KIDs arrays.In this work,an effective method is introduced to suppress the electromagnetic crosstalk and achieve a compact pixel distribution and small frequency intervals.The electromagnetic crosstalk is first analyzed by simulating the behavior of two neighboring pixels,and the physical distance and the frequency interval are optimized.Then,the arrangement of the pixels on the whole array is redesigned using a genetic algorithm to satisfy the requirements.The simulation results reveal that the normalized electromagnetic crosstalk can be reduced to 0.5%on an 8×8 array.Larger arrays of 16×16 pixels have been fabricated and measured to validate this method,and the results reveal that both the resonance property and survival rate of pixels are improved effectively with this method.This method will be very helpful for designing high-multiplexing KIDs arrays within a limited bandwidth.

文摘CO_(2) and CH_(4) as major causes of global warming could both be eliminated to produce syngas undermild conditions through dry reforming methane driven by electromagnetic induction heating(EMIH-controlled DRM).Using EMIH-configured characterization and density functional theory,it is shownthat the EMIH-induced negative electric field at the electromagnetic interface facilitates CO_(2) dissociation and atomic oxygen transfer,which is the source of the promoting effect of EMIH.By employing pure H2 in a one-step high-temperature reduction process,the interfacial effect between the NiMgAl compound and the Fe fiber could be improved,thereby increasing the influence of the EMIH-induced electric field.Consequently,the R-NiMgAl/Fe fiber catalyst with EMIH achieves about 90%conversions of CH_(4) and CO_(2) at 500℃,while traditional heating-driven DRM on R-NiMgAl requires 700℃ to accomplish the same result.
文摘Objective: This study evaluates the impact of handshake and information support on patients’ outcomes during laparoscopic cholecystectomy. It examines the effects on their physiological and psychological responses and overall satisfaction with nursing care. Methods: A total of 84 patients scheduled for laparoscopic cholecystectomy were selected through convenient sampling and randomly assigned to either the control group or the intervention group using a random number table. Each group consisted of 42 patients. The control group received standard surgical nursing care. In addition to standard care, the intervention group received handshake and information support from the circulating nurse before anesthesia induction. Vital signs were recorded before surgery and before anesthesia induction. Anxiety levels were measured using the State-Trait Anxiety Inventory (STAI) and the State-Anxiety Inventory (S-AI), while nursing satisfaction was assessed using a numerical rating scale. Results: No significant differences were found between the two groups in systolic and diastolic blood pressures before surgery and anesthesia induction (P > 0.05). However, there was a significant difference in heart rate before anesthesia induction (P Conclusion: Providing handshake and information support before anesthesia induction effectively reduces stress, alleviates anxiety, and enhances comfort and satisfaction among patients undergoing laparoscopic cholecystectomy.
