BACKGROUND Cardiovascular side effects occur frequently during anti-cancer treatment, and there is a growing concern that they may lead to premature morbidity and death. CASE SUMMARY A 32-year-old woman was diagnosed with breast cancer. After comprehensive treatment with neoadjuvant chemotherapy, surgery, postoperative adjuvant chemotherapy, postoperative adjuvant radiotherapy, and endocrine therapy, her breast cancer was cured. However, heart failure associated with anti-cancer treatment presented, most probably related to chemotherapy containing anthracycline. After active treatment, her cardiac function returned to normal. Unfortunately, follow-up visits revealed a second primary malignancy, lymphoma. After multiple courses of chemotherapy combined with targeted therapy, her lymphoma acquired complete remission and no cardiotoxicity was observed again. Heart failure related to breast treatment may be reversible. CONCLUSION Using alternatives to anthracycline in patients with lymphoma who are at risk of cardiac failure may preserve cardiac function.

A new alkaline pressure oxidative leaching process(with NaNO3 as the oxidant and NaOH as the alkaline reagent)is proposed herein to remove arsenic,antimony,and lead from bismuth-rich and arsenic-rich lead anode slime for bismuth,gold,and silver *** effects of the temperature,liquid-to-solid ratio,leaching time,and reagent concentration on the leaching ratios of arsenic,antimony,and lead were investigated to identify the optimum leaching *** experimental results under optimized conditions indicate that the average leaching ratios of arsenic,antimony and lead are 95.36%,79.98%,63.08%,respectively.X-ray diffraction analysis indicated that the leaching residue is composed of Bi,Bi2O3,Pb2Sb2O7,and trace amounts of NaSb(OH)***,antimony,and lead are thus separated from lead anode slime as Na3AsO4·10H2O and *** electron microscopy and energy-dispersive spectrometry imaging revealed that the samples undergo appreciable changes in their surface morphology during leaching and that the majority of arsenic,lead,and antimony is removed.X-ray photoelectron spectroscopy was used to demonstrate the variation in the valence states of the arsenic,lead,and *** Pb(IV)and Sb(V)content was found to increase substantially with the addition of NaNO3.

Neural stem/progenitor cells (NSCs) could be attractive therapeutic targets for promoting adult neurogenesis, brain plasticity, and repair in stroke and neurodegenerative diseases, raising great potentials for regeneration therapy. In adult ischemic brains, NSCs have limited capacities of growth, differentiation, and generating new neurons for repairing the damaged central nervous system. However, the spontaneous brain repair seems to be insufficient to recover neurological deficits in most stroke cases. To overcome those problems, pharmacological manipulations targeting on endogenous NSCs or transplanted stem cells could be a promoting strategy for regeneration therapy. Chinese herbal medicine has great potentials for developing novel therapeutic strategies for adult neurogenesis and brain repair in poststroke treatment. Chinese herbal medicine has a long history for poststroke treatment. Recent studies create great opportunity for drug discovery for promoting neurogenesis and improving the recovery of neurological fimctions in poststroke treatment. Many active compounds or extracts from medicinal herbs have shown promising effects on regulating proliferation, self-renewal and differentiation of NSCs, and promoting neural network formation as well as neurological functional recovery with in vitro and in vivo experimental evidence. Therefore, targeting neural stem/progenitor cells can be an important opportunity for the studies of Traditional Chinese Medicine in regeneration medicine. Due to the complex interactions of herbal ingredients in network regulation, huge challenge remains to be resolved for further study.

The effect of NaNO_3 concentration on the anodic electrochemical behavior of antimony in 4 M NaOH solution was investigated using cyclic voltammetry(CV) and electrochemical impedance spectroscopy(EIS) analyses. The mechanism of NO_3^-concentration effect on the anodic electrochemical behavior of antimony was proposed, and its availability was confirmed by experimental results. The effect of NaNO_3 on the anodic behavior of antimony in Na OH solution can be interpreted as a stepwise formation of different antimony compounds with different NaNO_3 concentrations. Metallic antimony is apt to be oxidized into Sb_2O_3 within the NaNO_3 concentration range of 0–0.48 M. NaSbO_3 can be found on the antimony surface when the NaNO_3 concentration increases gradually. Insoluable NaSbO_3 inhibits the anodic oxidation of antimony due to its shielding effect on the mass transport of the reactants and products. Surface morphology and composition were analyzed by X-ray photoelectron spectroscopy(XPS), scanning electronic microscopy(SEM), and electron dispersion spectroscopy(EDS) analyses. Results indicate that the anodic oxidation layer is composed of Sb_2O_3, NaSbO_3, and Sb. The atomic proportion of antimony in the form of NaSbO_3 increases with increasing NaNO_3 concentration due to the powerful oxidizing property of NaNO_3.

Quantum-to-classical transition is a fundamental open question in physics frontier. Quantum decoherence theory points out that the inevitable interaction with environment is a sink carrying away quantum coherence, which is responsible for the suppression of quantum superposition in open quantum ***, quantum Darwinism theory further extends the role of environment, serving as communication channel, to explain the classical objectivity emerging in quantum measurement process. Here, we used a six-photon quantum simulator to investigate classical and quantum information proliferation in quantum Darwinism process. In the simulation, many environmental photons are scattered from an observed quantum system and they are collected and used to infer the system's state. We observed redundancy of system's classical information and suppression of quantum correlation in the fragments of environmental photons. Our results experimentally show that the classical objectivity of quantum system can be established through quantum Darwinism mechanism.

In order to take a precise and objective evaluation on asphalt-aggregate adhesion, this paper analyzed the function at asphalt- aggregate interface using surface free energy theory. Two asphalts and two aggregates were selected and their surface free energy parameters, FLW, F and F-, were measured by the Wilhelmy plate method and the column wicking technique, respectively. Then, the resistance to moisture damage of asphalt mixture were predicted using calculated asphalt-aggregate adhesive bond energy and asphalt cohesive bond energy. The results show that moisture damage is a thermodynamically favorable phenomenon. Asphalt with a great acid-base polar component and a low Lifshitz-van der Waals apolar component always exhibits perfect cohesion.
