Acute leukemia is a malignant tumor originating from the hematopoietic system with the highest incidence and mortality. At present, the main clinical treatment of leukemia is still chemotherapy, during the course of which the multidrug resistance (MDR) will significantly reduce remission rate and disease-free survival rate of patients. MDR is the most important factor affecting refractory/recurrent acute leukemia. Therefore, reversing leukemia MDR is one of the best ways to improve the complete remission rate of refractory/recurrent acute leukemia, and the study of drugs and methods to overcome leukemia MDR has received extensive attention in the leukemia research field. This study was to primarily investigate the effects of Liushen pills on leukemia drug-resistant cell line K562/DOX in inhibiting growth, reversing resistance and inducing apoptosis in anticipation of providing useful cytological and molecular biological basis for the treatment of refractory/recurrent acute leukemia. The serum containing toad venom was prepared by means of Chinese drug serum pharmacology. MTT assay was used to detect the inhibitory rates of human leukemia cell line K562/DOX after being treated with the serum containing toad venom as well as daunorubicin, or with the serum containing toad venom alone at different time points. Real-time fluorescent quantitative analysis (RT-PCR) was performed to determine the effects of serum containing toad venom on the expression of BCL-2 mRNA in human leukemia cell line K562/DOX. Compared to the control group, toad venom showed inhibitory effects on K562/DOX cells; the expression level of BCL-2 mRNA in toad venom group were decreased, indicating that toad venom may reverse the resistance of K562/DOX cells by down-regulating the expression level of MDR1.
Quantum Coherent Dissociation in a Hybrid Atom-light System with Photon Loss
Xiaoyang Yuan,Jialu Yin,Jiahao Xu,Yixiao Huan,Zhengda Hu 한국광학회 2024 Current Optics and Photonics Vol.8 No.1
We investigate the effect of photon loss on pair production in a hybrid atom-light system. The loss of light field not only affects the generation of photons, but also prevents the generation of atomic collective excitation, although the atoms are not influenced directly. We propose an unbalanced homodyne detection of the number of atomic collective excitation that overcomes the challenge caused by counting uncertainty in practical measurement. In discussion, we show that the intermode correlations and the number correlation is closely related to the initial input state, while the quadrature correlations are independent of the initial state and always exhibit opposite intermode correlations even in the presence of loss.
Modulation Recognition of BPSK/QPSK Signals based on Features in the Graph Domain
Li Yang,Guobing Hu,Xiaoyang Xu,Pinjiao Zhao 한국인터넷정보학회 2022 KSII Transactions on Internet and Information Syst Vol.16 No.11
The performance of existing recognition algorithms for binary phase shift keying (BPSK) and quadrature phase shift keying (QPSK) signals degrade under conditions of low signal-to-noise ratios (SNR). Hence, a novel recognition algorithm based on features in the graph domain is proposed in this study. First, the power spectrum of the squared candidate signal is truncated by a rectangular window. Thereafter, the graph representation of the truncated spectrum is obtained via normalization, quantization, and edge construction. Based on the analysis of the connectivity difference of the graphs under different hypotheses, the sum of degree (SD) of the graphs is utilized as a discriminate feature to classify BPSK and QPSK signals. Moreover, we prove that the SD is a Schur-concave function with respect to the probability vector of the vertices (PVV). Extensive simulations confirm the effectiveness of the proposed algorithm, and its superiority to the listed model-driven-based (MDB) algorithms in terms of recognition performance under low SNRs and computational complexity. As it is confirmed that the proposed method reduces the computational complexity of existing graph-based algorithms, it can be applied in modulation recognition of radar or communication signals in real-time processing, and does not require any prior knowledge about the training sets, channel coefficients, or noise power.

One-dimensional CdTe nanorods (NRs) are obtained by the reaction of various Cd precursors with single crystalline Te nanorod templates, which are pre-synthesized from Te precursors by a simple and reproducible solvothermal method. Throughout the process, the diffraction intensity of different crystal facets of single crystalline Te NRs varied with reaction times. Finally, by alloying Cd ions along the axial direction of Te NRs, polycrystalline cubic phase CdTe NRs with diameters of 80-150 nm and length up to $1.2-2.4{\mu}m$ are obtained. The nucleation and growth processes of Te and CdTe NRs are discussed in details, and their properties are characterized by XRD, SEM, TEM, Raman scattering, and UV-vis absorption spectra. It was found that the key elements of synthesizing CdTe NRs such as reaction temperatures and Cd sources will strongly influence the final shape of CdTe NRs.
