Our finding not only can provide ocean-wave parameters but also can offer significant and accurate data support for cloud computing of ocean big data.Ni-rich Li[NixCoyMn1-x-y]O2 (NCM) cathode materials have attracted great research interest owing to their high energy density and relatively low cost. However, capacity fading because of parasitic side reactions, mainly occurring at the interface with the electrolyte, still hinders widespread application in advanced Li-ion batteries (LIBs). Surface modification via coating is a feasible approach to tackle this issue. Nevertheless, achieving uniform coatings is challenging, especially when using wet chemistry methods. In this work, a protective alumina shell on NCM701515 (70% Ni) was prepared through the reaction of surface-active -OH groups with trimethylaluminum as the precursor. The coated NCM701515 shows significantly improved capacity retention over uncoated (pristine) NCM701515. Part of the reason is the lower impedance buildup during cycling due to the effective suppression of adverse side reactions and secondary particle fracture. Taken together, the solution-based coating strategy described herein offers an easy way to apply surface treatment to stabilize Ni-rich NCM cathode materials in next-generation LIBs.Modifying different functional moieties into one platform is a conventional strategy for constructing theranostic systems. However, this strategy usually suffers from the unsatisfied efficiency of each individual function. Herein, a programmed self-assembly strategy is presented to fabricate theranostic nanoparticles, which significantly exhibit a dual-modality imaging function involving fluorescence imaging and magnetic resource imaging (MRI), and an efficient targeted therapy to cancer cells. Fluorescent vesicles are first self-assembled by aggregation-induced emission (AIE)-active molecules. Gd3+, serving as an MRI agent, is subsequently bound to the vesicles to provide highly positive charges, which have been realized to be anticancer active. Thereafter, transferrin (Tf) protein is introduced onto the surface of Gd3+ coordinated vesicles, shielding the positive charges and making the nanoparticles nontoxic to cells. With the assistance of Tf protein, the constructed nanoparticles are specifically targeted to cancer cells. Moreover, Tf proteins further peel off from nanoparticles in lysosomes due to their charge reversion, resulting in highly positive charges and heavy toxicity of nanoparticles to kill cancer cells.

This strategy holds great potential for theranostic nanomedicine.Background Predictors of long-term outcome and optimal catheter set for ablation of cavo-tricuspid isthmus (CTI) in patients with atrial flutter (AFL) are not well known. Aims To identify predictors of events during outcome following ablation. Methods We studied 741 patients (mean 62.2 [10.8] years, 248 females) who were followed for 4.4 [2.7] years. Two- vs three-electrode approach and clinical predictors of events during follow-up were analyzed. Results Two-electrode approach was faster (62.5 [30.3] vs 101.4 [51] min, P less then 0.001), with less fluoroscopy (13.1 [9.3] vs 20.3 [12.4] min, P less then 0.001), cost-effective (8.29 [2.82] vs 11.89 [2.51] units, P less then 0.001) and more effective (92.1% vs 86.1%), P = 0.012). Independent predictors for AFL recurrence were Ca-blocker use (3.24 [1.64; 6.40]), mitral valve disease (MVD) (1.82 [1.12; 2.95]), previous stroke/TIA (2.38 [1.21; 4.65]), pulmonary artery dilatation (3.94 [1.22; 12.73]), previous pulmonary embolism (3.77 [1.14; 12.43]); for atrial fibrillation (AF) previous AF (6.054 [4.58; 8.00]), left atrial enlargement (1.43 [1.12; 1.81]), # of antiarrhythmic drugs (1.16 [1.05; 1.28]), MVD (1.28 [1.04; 1.58]); for pacemaker implantation tachy-brady syndrome (6.17 [3.16; 12.05]), previous II/III0 atrio-ventricular block (29.40 [7.37; 117.28]), centrally acting hypotensive drugs (29.55 [6.14; 142.25]), aortic dilatation/aneurysm (2.58 [1.06; 6.30]), labile INR (3.45 [1.72; 6.93]), LBBB (4.70 [1.49; 14.82]), shortest RR interval during AFL (1.003 [1.001; 1.005]), previous cardiac surgery (2.69 [1.27; 5.70]), aortic valve disease (2.22 [1.08; 4.59]). Conclusion Ablation of CTI with minimal number of electrodes is safe and effective. There are specific predictors of events during long-term outcome.In half of newly detected cases of HIV infection in Europe, the diagnosis is made late. This has significant impact on the effects of antiretroviral therapy, long-term consequences of the disease, mortality, and the risk of HIV transmission in the environment. As part of the large "STOP Late Presenters" project, the number of HIV tests was assessed in four multi-specialist hospitals in the Mazowieckie voivodeship, which generally carry out over 112,000 hospitalizations per year. First, under the structured research program, the training of medical personnel was carried out in these hospitals, and then the number of HIV tests ordered was evaluated 2 months and 4 months after the training. 459 HIV tests were performed after the training in all hospitals, which is 2.44% of hospitalizations. It is interesting to note that after 4 months, the number of performed tests fell significantly. Staff training resulted in the number of tests higher by 5.8 %, compared to the same period of previous year. Four positive results were confirmed, which is 0.87% of all tests done. This is almost twice higher than in other European countries. Tests for HIV infection are most often ordered by doctors of infectious diseases, gynecologists and the staff of dialysis departments. We found that there is little interest in HIV testing among other specialists, despite reporting patients with clinical symptoms that suggest the likelihood of this infection. The improvement in HIV testing is of great importance for public health in our country and requires modification of diagnostic algorithms in hospital wards to reduce the number of late diagnoses of HIV / AIDS.
