Simple security proof of coherent-one-way quantum key distribution.

Coherent-one-way quantum key distribution (COW-QKD), which requires a simple experimental setup and has the ability to withstand photon-number-splitting attacks, has been not only experimentally implemented but also commercially applied. However, recent studies have shown that the current COW-QKD system is insecure and can only distribute secret keys safely within 20 km of the optical fiber length. In this study, we propose a practical implementation of COW-QKD by adding a two-pulse vacuum state as a new decoy sequence.

Protocol for Comparing the Efficacy of Three Reconstruction Methods of the Digestive Tract (Kamikawa Versus Double-Tract Reconstruction Versus Tube-Like Stomach) After Proximal Gastrectomy.

Background: Appropriate gastrointestinal reconstruction after proximal gastrectomy can effectively reduce the incidence of postoperative complications in patients with proximal early gastric cancer. However, there is still great controversy about the choice of digestive tract reconstruction after proximal gastrectomy, and there is no clinical consensus on the choice of digestive tract reconstruction after proximal gastrectomy. Currently, there is a lack of large-sample, prospective, randomized controlled studies to compare the efficacy of Kamikawa, double-tract reconstruction, and tube-like stomach reconstruction after proximal gastrectomy.

Are preoperative oral antibiotics effective in reducing the incidence of anastomotic leakage after colorectal cancer surgery? Study protocol for a prospective, multicentre, randomized controlled study.

Introduction: The optimal preoperative preparation for elective colorectal cancer surgery has been debated in academic circles for decades. Previously, several expert teams have conducted studies on whether preoperative mechanical bowel preparation and oral antibiotics can effectively reduce the incidence of postoperative complications, such as surgical site infections and anastomotic leakage. Most of the results of these studies have suggested that preoperative mechanical bowel preparation for elective colon surgery has no significant effect on the occurrence of surgical site infections and anastomotic leakage.

Secure and practical multiparty quantum digital signatures.

Quantum digital signatures (QDSs) promise information-theoretic security against repudiation and forgery of messages. Compared with currently existing three-party QDS protocols, multiparty protocols have unique advantages in the practical case of more than two receivers when sending a mass message. However, complex security analysis, numerous quantum channels and low data utilization efficiency make it intractable to expand three-party to multiparty scenario.

Suppression of TCAB1 expression induced cellular senescence by lessening proteasomal degradation of p21 in cancer cells.

Background: TCAB1, a.k.a.

S100A4+ macrophages facilitate zika virus invasion and persistence in the seminiferous tubules via interferon-gamma mediation.

Testicular invasion and persistence are features of Zika virus (ZIKV), but their mechanisms are still unknown. Here, we showed that S100A4+ macrophages, a myeloid macrophage subpopulation with susceptibility to ZIKV infection, facilitated ZIKV invasion and persistence in the seminiferous tubules. In ZIKV-infected mice, S100A4+ macrophages were specifically recruited into the interstitial space of testes and differentiated into interferon-γ-expressing M1 macrophages.

The prognostic potential of coilin in association with p27 expression in pediatric acute lymphoblastic leukemia for disease relapse.

Background: Cajal body (CB) is a nucleic organelle where small nuclear ribonucleoproteins undergo modification, maturation, splicing and/or assembly. Coilin is the marker structural protein of CBs. The expression level and cellular localization of coilin is sensitive to chemotherapeutic reagents, such as cisplatin.

[Changes in expression of autophagy-related factors during acute contusion repair of skeletal muscle].

Objectives: To explore the possible biological mechanism of skeletal muscle contusion repair through researching the changes in expression of autophagy-related genes and proteins in SD rats with acute skeletal muscle contusion.

Methods: Six rats were randomly selected as the control group from 30 male SD rats, acute skeletal muscle contusion model were established in the remaining 24 rats with self-made hitter, then the model rats were randomly divided into 4 groups (3 d, 5 d, 7 d, 14 d groups, =6). On the 3, 5, 7 and 14 day after injury, injured gastrocnemius of each group was harvested.

[Effects of Electroacupuncture on Adaptive Hypertrophy of Gastrocnemius and Proliferation and Differentiation of Muscle Satellite Cells in Rats].

Objective: To explore the effects and mechanism of different duration electroacupuncture (EA) on adaptive hypertrophy of gastrocnemius and the expressions of proliferation cell nuclear antigen (PCNA), paired box transcription factor 7 (Pax 7), myogenic differentiation antigen (MyoD 1), myogenin (MyoG), myosin heavy chain-Ⅰ(Myh 7), transforming growth factor-β 1 (TGF-β 1), Smad 3 in rats.

Methods: Twenty-four SD adult male rats were randomly divided into normal, two-week EA (A 2), four-week EA (A 4) and eight-week EA (A 8) groups, 6 rats in each group. Except the normal group, EA was applied at right "Zusanli" (ST 36) and "Huantiao" (GB 30) for 10 min in the other three groups, separately for 2 weeks, 4 weeks and 8 weeks, once a day, 6 times a week.

Automatic schizophrenic discrimination on fNIRS by using complex brain network analysis and SVM.

Background: Schizophrenia is a kind of serious mental illness. Due to the lack of an objective physiological data supporting and a unified data analysis method, doctors can only rely on the subjective experience of the data to distinguish normal people and patients, which easily lead to misdiagnosis. In recent years, functional Near-Infrared Spectroscopy (fNIRS) has been widely used in clinical diagnosis, it can get the hemoglobin concentration through the variation of optical intensity.

[The Effect of Electroacupuncture Combined with Treadmill Training on Skeletal Muscle Contusion in Rats].

Objective: To study the effect and mechanism of electroacupuncture(EA)combined with treadmill training in rats with skeletal muscle contusion.

Methods: A total of sixty Sprague Dawley rats were randomly divided into normal,model, EA, treadmill, and combination groups (=12/group). The self-made striking device was used to establish skeletal muscle contusion model.

Reliable HPLC separation, vibrational circular dichroism spectra, and absolute configurations of isoborneol enantiomers.

Resolution of chiral compounds has played an important role in the pharmaceutical field, involving detailed studies of pharmacokinetics, physiological, toxicological, and metabolic activities of enantiomers. Herein, a reliable method by high-performance liquid chromatography (HPLC) coupled with an optical rotation detector was developed to separate isoborneol enantiomers. A cellulose tris(3, 5-dimethylphenylcarbamate)-coated chiral stationary phase showed the best separation performance for isoborneol enantiomers in the normal phase among four polysaccharide chiral packings.
