Background: CCL11, a chemokine known for recruiting immune cells to the tumor microenvironment (TME), has an unclear role in the context of its expression, patient prognosis, and the presence of tumor-infiltrating immune cells (TILs) in breast cancer.

Methods: The expression of CCL11 in invasive breast cancer (BRCA) was analyzed using TCGA database. Survival curve and Cox regression analysis determined the potential of CCL11 as an independent prognostic indicator.

Background: ) participates in tumor resistance by playing the function of homologous recombination repair(HRR). However, the role of in non-small cell lung cancer (NSCLC) is still unclear. This study aims to understand the expression of in NSCLC and preliminarily explore its relationship with cisplatin resistance.

In this paper, the chemical vapor deposition (CVD) processing for 4H-SiC epilayer is investigated with particular emphasis on the defects and the noise properties. It is experimentally found that the process parameters of C/Si ratio strongly affect the surface roughness of epilayers and the density of triangular defects (TDs), while no direct correlation between the C/Si ratio and the deep level defect Z could be confirmed. By adjusting the C/Si ratio, a decrease of several orders of magnitudes in the noise level for the 4H-SiC Schottky barrier diodes (SBDs) could be achieved attributing to the improved epilayer quality with low TD density and low surface roughness.

Electrical noise significantly limits the detectivity of infrared photodiode detectors. In this paper, we investigated the dark current and noise spectra for long-wave-infrared InAs/GaSb type-II superlattice (T2SL) detectors to study the origin of noise under various work conditions. The temperature-dependent I-V characteristics reveal a turning point near 90 K, below which the dominant dark current mechanism changes from Shockley-Hall-Read generation current and diffusion current to shunt current and trap-assisted tunneling (TAT) current.

We describe the isolation of strain JA and demonstrate that this bacterium exhibited strong algicidal effects on the algae with an inhibition rate exceeding 80 % within 48 h JA significantly reduced the photosynthetic efficiency of and caused extensive morphological damage to the algae. Genomic analysis of JA demonstrated that a putative AI-2 type quorum sensing (QS) gene () is present in its genome cluster, which is regulate pheromone biosynthesis. Interestingly, the exogenous addition of a QS-oligopeptide (ComX-pheromone) improved the algicidal efficiency of JA, thus indicating that the algicidal activity of this bacterium is potentially regulated by QS.

The Acinetobacter baumanni J1 isolated from surface water of the Eastern Pacific Ocean, demonstrated significant algicidal activity on the algae Alexandrium tamarense. Interestingly, this strain showed the ability to produce an acyl-homoserine lactone (AHL) quorum sensing molecule. To better understand its AHL producing mechanism and its ecological functions, the genome of A.

Background: Adipocytokines were known to play a relevant role in metabolism, inflammation responses and carcinogenesis of several malignancies. Our aims were to detect the expression of serum adipocytokines, explore their potential diagnostic ability and relationship with clinicopathological characteristics of lung cancer.

Methods: Adipocytokines, insulin-like growth factor binding protein 1 (IGFBP-1), resistin, tumor necrosis factors (TNFα), TNF RI and TNF RII, vascular endothelial growth factor (VEGF), leptin, interleukin (IL)-6 and IL-10, chemerin, brain-derived neurotrophic factor (BDNF), plasminogen activator inhibitor-1 (PAI-1) were assessed in 49 untreated lung cancer patients and 20 healthy controls.
