Integrative cultivation practices(ICPs)are essential for enhancing cereal yield and resource use ***,the effects of ICP on the rhizosphere environment and roots of paddy rice are still poorly *** this study,four rice varieties were produced in the *** variety was treated with six different cultivation techniques,including zero nitrogen application(0 N),local farmers’practice(LFP),nitrogen reduction(NR),and three progressive ICP techniques comprised of enhanced fertilizer N practice and increased plant density(ICP1),a treatment similar to ICP1 but with alternate wetting and moderate drying instead of continuous flooding(ICP2),and the same practices as ICP2 with the application of organic fertilizer(ICP3).The ICPs had greater grain production and nitrogen use efficiency than the other three *** length,dry weight,root diameter,activity of root oxidation,root bleeding rate,zeatin and zeatin riboside compositions,and total organic acids in root exudates were elevated with the introduction of the successive cultivation *** enhanced nitrate nitrogen,the activities of urease and invertase,and the diversity of microbes(bacteria)in rhizosphere and non-rhizosphere soil,while reducing the ammonium nitrogen *** nutrient contents(ammonium nitrogen,total nitrogen,total potassium,total phosphorus,nitrate,and available phosphorus)and urease activity in rhizosphere soil were reduced in all treatments in comparison with the non-rhizosphere soil,but the invertase activity and bacterial diversity were *** main root morphology and physiology,and the ammonium nitrogen contents in rhizosphere soil at the primary stages were closely correlated with grain yield and internal nitrogen use *** findings suggest that the coordinated enhancement of the root system and the environment of the rhizosphere under integrative cultivation approaches may lead to higher rice production.

By simply switching the electrical circuit installed on steel/steel contact,the tribological behaviors of nanofluids(NFs)can be regulated in real time,thereby achieving the desired performance of friction reduction and wear ***,solvent-free carbon spherical nanofluids(C-NFs)were successfully prepared for intelligent lubrication regulation.C-NFs with excellent lubrication performance can immediately reduce the coefficient of friction(COF)despite applying a weak electric potential(1.5 V).Moreover,polyethylene glycol 400(PEG400)containing 5.0 wt%C-NFs remained responsive to electrical stimulation under the intermittent voltage application with an average coefficient of friction(ACOF)reduction of 20.8%over *** intelligent lubrication regulation of C-NFs under an external electric field(EEF)mainly depends on the orderly arranged double-electric adsorption film of ion canopy-adsorbed carbon spheres(CSs).The intermittent electrical application can continuously reinforce the adsorption film and its durability for real-time controlling the sliding ***-stimulation-responsive intelligent lubricants provide a new technical support for realizing intelligent stepless control of devices.

Targeted axillary dissection after neoadjuvant chemotherapy for highly selective patients with initial cN1 breast cancer:A single-center prospective trial

引用

Chinese Medical Journal 2024年第12期137卷 1421-1430页

作者： Xiuchun Chen Zhenduo Lu Chengzheng Wang minhao Lyu Jianghua Qiao Xianfu Sun Lianfang Li Chongjian zhang Zhenzhen Liu Department of Breast Disease The Affiliated Cancer Hospital of Zhengzhou University&Henan Cancer HospitalZhengzhouHenan 450008China

Background:Sentinel lymph node(SLN)biopsy is gradually accepted as the standard of care in breast cancer patients with down-staged axillary disease after neoadjuvant chemotherapy(NAC).However,it is still difficult to precisely define pre-NAC clinical node-positive(cN1)and post-NAC clinical node-negative(ycN0).This prospective single-center trial was designed to evaluate the feasibility and accuracy of standard targeted axillary dissection(TAD)after NAC in highly selective pre-NAC cN1 patients(not considering ultrasound-based axillary ycN staging).Methods:This prospective trial included patients with initial pre-NAC cT1-3N1M0 invasive breast cancer but with a rigorous definition of cN1 from the Affiliated Cancer Hospital of Zhengzhou *** NAC was effective(including complete and partial responses)and preoperative axillary palpation was negative,preoperative ultrasound-based axillary staging was not considered,and all patients underwent TAD followed by axillary lymph node(LN)*** detection rate(DR)and false-negative rate(FNR)of TAD were ***:A total of 82 patients were included,and 77 of them were eligible for data *** DR for TAD was 94.8%(73/77).There were 26 patients with one abnormal LN at the time of diagnosis based on ultrasound,45 patients with two,and 2 patients with *** patient had one TAD LN,four patients had two TAD LNs,and 68 patients had three or more TAD *** axillary palpation yielded negative results for all 73 patients who successfully underwent *** ultrasound-based ycN0 and ycN+conditions were detected for 52 and 21 cases,*** FNR was 7.4%(2/27)for standard TAD(≥3 SLNs),which was lower than that of all successful TAD(≥1 SLN;10.0%,3/30).Conclusions:In rigorously defined pre-NAC cN1 breast cancer patients,standard TAD is feasible for those with negative axillary palpation after NAC,and FNR is also less than 10%.Registration:***,ChiCTR2100049093.
