Radiotherapy interruption (RTI) prolongs the overall total treatment time and leads to local control loss in many cancers, but it is unclear in esophageal cancer. We aimed to evaluate the influence of RTI on the overall survival (OS), progression-free survival (PFS), and local-regional recurrence-free survival (LRFS) of patients with esophageal cancer undergoing chemoradiotherapy.

To elucidate these issues, a detailed study of the microstructure of amorphous V2O5 under pressure was needed. The spatial distributions of atoms, the link distributions and the geometrical distributions of the free volumes need to be fully investigated. The distribution of free volume in the amorphous V2O5 network also needs to be visualized. These are the main contents in this paper.

The role of complex surface defect on the magnet at the (110) surface of bismuth sodium titanate (Bi0.5Na0.5TiO3) was discussed based on the first-principles calculation. The first-principle calculations for various types of surface defects exhibited the existence of magnetic moments for selected chemical and position defects.

In ebook "Complex macromolecular systems II (Advances in polymer science, Volume 228)" the combination and interplay of these well-balanced “internal fields” with “external fields” such as mechanical, electrical, magnetic, electromagnetic, and/or the interactions with surfaces are a powerful tool to create defect-free and perfectly ordered macromolecular structures on a macroscopic scale, leading to new material properties, processes, and applications.

As clinical signs and symptoms of nasopharyngeal carcinoma (NPC) are often nonspecific, it is difficult to detect in the early stage, leading to high risk of relapse or recurrent metastasis. Plasma cell-free DNA of Epstein-Barr virus (cf-EBV DNA) is markedly associated with the development of undifferentiated NPC, and its level prior and subsequent to treatment is reliable for the screening, diagnosis, monitoring and prognosis of NPC.

With the in-depth research on the tumor microenvironment, the tumor stroma is considered to play a leading role in malignant tumor behavior, and PD-L1 is also related to the tumor stroma. The tumor–stroma ratio (TSR) has been regarded as a novel prognostic factor in many cancers. Our study aims to assess the TSR and PD-L1 clinical value in hepatocellular carcinoma (HCC) patients.

Although the standard therapy for advanced-stage hepatocellular carcinoma (HCC) is systemic chemotherapy, the combination of atezolizumab and bevacizumab (atezo+bev) with a high objective response rate may lead to conversion to resection in patients with initially unresectable HCC. This study aims to evaluate the efficacy of atezo+bev in achieving conversion surgery and prolonged progression-free survival (PFS) for initially unresectable HCC.

Solar radiation and wind provide the temporal temperature fluctuation for heating and cooling. 0.005La eNa0.5Ba0.5TiO3-0.06BaTiO3-0.002Ta is found as the best suitable material for energy harvesting. The voltage and power output are further improved by tuning operating frequency, load capacitance and resistance.

Hepatocellular carcinoma (HCC) is one of the leading causes of cancer-related deaths worldwide. Sorafenib is the first-line treatment for advanced HCC, but the anti-cancer effects remain to be improved as indicated by its low response rates and failure to prolong the progression-free survival (PFS).

Nucleosomes consist of DNA wrapped around a histone octamer core like thread on a spool to condense DNA as chromatin into chromosomes. Diseases such as cancer or inflammation lead to cell death, chromatin fragmentation and release of nucleosomes into the blood.

Nucleosomes consist of DNA wrapped around a histone octamer core like beads on a string so that DNA can be condensed as chromatin into chromosomes. Diseases such as cancer or inflammation lead to cell death where chromatin is fragmentated and released as mononucleosomes into the blood.

The European bison is an endangered species, and as such it is extremely important to monitor herds for pathogens which can lead to reproductive failure. The aim of the present study was to determine the current prevalence of antibodies to pathogens known to potentially influence reproduction in European bison.

The ability of the hyperthermophilic archaeon Sulfolobus solfataricus P2 to grow on organic and inorganic sulfur sources was investigated. A sulfur-free mineral medium was employed with different sources of carbon. The results showed that inorganic sulfur sources display growth curve patterns significantly different from the curves obtained with organic sulfur sources. Combustion of fossil fuels leads to the atmospheric emission of sulfur oxides that contribute to acid rain and air pollution.

The experimental results showed that with an increase of the TS temperature, the structure of the ceramics transformed from an orthorhombic-tetragonal mixed phase (O-T) at TS 1100 °C into a rhombohedral-tetragonal (R-T) mixed phase with a dense microstructure of uniform grain size at TS = 1110 °C. When TS was further increased.
