Theoretical Prediction on Properties of 3,4-Bisnitrofurazanfuroxan (DNTF) Crystal and its Polymer Bonded Explosives (PBXs) Through Molecular Dynamics (MD) Simulation.

Context: 3,4-Bisnitrofurazanfuroxan (DNTF) is a typical high energy density compound (HEDC), it has high crystal density and detonation parameters, but also high mechanical sensitivity. To decrease its mechanical sensitivity, the DNTF based polymer bonded explosives (PBXs) was designed. The pure DNTF crystal and PBXs models were established.

Designing and property prediction of a novel three-component CL-20/HMX/TNAD energetic cocrystal explosive by MD method.

Context: Cocrystallization technology can effectively regulate crystal structure, alter packing mode, and improve physicochemical performances of energetic materials at molecule level. CL-20/HMX cocrystal explosive has high energy density than HMX, but it also exhibits high mechanical sensitivity. To decrease the sensitivity and improve the properties of CL-20/HMX energetic cocrystal, the three-component energetic cocrystal CL-20/HMX/TNAD was designed.

Theoretical research on performances of CL-20/HMX cocrystal explosive and its based polymer bonded explosives (PBXs) by molecular dynamics method.

In this article, the CL-20/HMX cocrystal model was established and its based polymer bonded explosives (PBXs) were designed. The static performances, including mechanical properties, stability and detonation performance of CL-20/HMX cocrystal model and PBXs models, were predicted by molecular dynamics (MD) method. The mechanical parameters, binding energy, and detonation parameters of PBXs models were calculated and compared with that of pure CL-20/HMX cocrystal model.

Highly sensitive fluorescent detection of EDIL3 overexpressed exosomes for the diagnosis of triple-negative breast cancer.

EDIL3 is a strong and highly accurate diagnostic marker for breast cancer, meanwhile, EDIL3 overexpressed exosomes are novel biomarkers for the early diagnosis of triple-negative breast cancer (TNBC). Here, we proposed a fluorescent detection method for EDIL3 overexpressed exosomes, which is simple and sensitive. Basically, we utilized a magnetic nanospheres (MNS) based liquid sandwich immunoassay strategy.

Real-World Prescription Patterns For Patients With Young-Onset Parkinson's Disease in China: A Trend Analysis From 2014 to 2019.

Pharmacotherapy is one of the main treatments for patients with young-onset Parkinson's disease (YOPD). Although numerous studies on the treatment of YOPD have been published, the real-world prescription patterns of these populations remain unclear in China. A national comprehensive evaluation was performed to reveal the pharmacological treatment patterns in Chinese patients with Parkinson's disease from 1 January 2014 to 31 December 2019, with patients aged 21-50 years classified as having YOPD for the subgroup analysis.

Theoretical investigations on stability, sensitivity, energetic performance, and mechanical properties of CL-20/TNAD cocrystal explosive by molecular dynamics method.

The crystal models of trans-1,4,5,8-tetranitro-1,4,5,8-tetraazadecalin (TNAD), hexanitrohexaazaisowurtzitane (CL-20), and CL-20/TNAD cocrystal explosive with different component ratios were established. Molecular dynamics (MD) method was applied to predict the stability, sensitivity, energetic properties, and mechanical properties. The effect of component ratio on properties of CL-20/TNAD cocrystal explosive was investigated and estimated.

Oridonin induces apoptosis via PI3K/Akt pathway in cervical carcinoma HeLa cell line.

Aim: To investigate the apoptosis-inducing effect of oridonin, a diterpenoid isolated from Rabdosia rubescens, in the human cervical carcinoma HeLa cell line.

Methods: A morphological analysis, nuclear condensation, and fragmentation of chromatin were monitored using Hoechst 33342 staining. Cell viability was assessed using the 3-(4, 5-dimethylthiazol-(2)-yl)-2, 5-diphenyl tetrazolium bromide (MTT) assay.
