Recent reports have suggested the involvement of gut microbiota in progression colorectal cancer (CRC). We utilized pyrosequencing based analysis 16S rRNA genes to determine overall structure patients with and healthy controls; we investigated intestinal lumen, cancerous tissue matched noncancerous normal tissue. Moreover, mucosa-adherent microbial composition using rectal swab samples because tissue-adherent bacterial community is potentially altered following bowel cleansing. Our findings...

Liver fibrosis is a disease largely driven by resident and recruited macrophages. The phenotypic switch of hepatic macrophages can be achieved chemo-attractants cytokines. During screening plants traditionally used to treat liver diseases in China, paeoniflorin was identified as potential drug that affects the polarization aim this study evaluate therapeutic effects an animal model explore its underlying mechanisms. induced Wistar rats via intraperitoneal injection CCl4.

The clinical value of the Syntax score in patients with non-ST segment elevation myocardial infarction (NSTEMI) has been well established. neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte (PLR), high sensitivity C-reactive protein (hsCRP)-albumin (hsCAR), and systemic immune-inflammatory (SII) index are promising inflammation (SI) biomarkers coronary artery diseases. However, studies which compare predicting these SI indicators NSTEMI limited.NSTEMI who underwent angiography (CAG) our...

Th cell differentiation is precisely regulated by thousands of genes at different stages. In the present study, we demonstrate that Dec2, a transcription factor belonging to bHLH (basic helix-loop-helix) superfamily, progressively induced during course Th2 differentiation, especially late stage. The up-regulated Dec2 can strongly promote development under Th2-inducing conditions, as evidenced retrovirus-mediated gene transfer or transgenic manipulation. addition, an enhancement responses...

The activation of the cyclic GMP‐AMP synthase‐stimulator interferon genes (cGAS‐STING) pathway has shown promise in enhancing antitumor immunity. However, involved de novo transcription and translation processes, which delays immune responses. Besides, rapid clearance secondary messenger (cGAMP) by extracellular hydrolase limits its availability, attenuating STING signaling resulting insufficient therapeutic efficacy. Herein, we constructed a DNA‐based nanocomplex, could restore cell‐cell...

Abstract Adverse skin reactions caused by ionizing radiation are collectively called dermatitis (RD), and the use of nanomedicine is an attractive approach to this condition. Therefore, we designed large-scale synthesized fullerenols that showed free radical scavenging ability in vitro. Next, pretreated X-ray-exposed cells with fullerenols. The results pretreatment significantly scavenged intracellular reactive oxygen species (ROS) produced enhanced antioxidant capacity, protecting from...

Breast cancer is the most common malignant tumor affecting women worldwide and divided into following subtypes: Luminal A, B, HER‑2 overexpression triple‑negative breast (TNBC). TNBC accounts for approximately 15‑20% of all cases. Due to characteristics low differentiation, likelyhood recurrence metastasis, strong invasiveness lack hormone receptors human epidermal growth factor receptor 2 (HER2), patients with cannot benefit from endocrine therapy or other available targeted agents....
