Traditional Chinese medicine (TCM), an ancient system of alternative medicine, played active role in the prevention and control COVID-19 China. It improved clinical symptoms patients, reduced mortality rate, recovery effectively relieved operating pressure on national medical during critical conditions. In light current global pandemic, TCM-related measures might open up a new channel other countries regions. Here, we summarize that were widely used China, including TCM guidelines, Wuchang...

Positron emission tomography (PET) has been widely used in clinical diagnosis for diseases and disorders. To obtain high-quality PET images requires a standard-dose radionuclide (tracer) injection into the human body, which inevitably increases risk of radiation exposure. One possible solution to this problem is predict image from its low-dose counterpart corresponding multimodal magnetic resonance (MR) images. Inspired by success patch-based sparse representation (SR) super-resolution...

Positron emission tomography (PET) images are widely used in many clinical applications, such as tumor detection and brain disorder diagnosis. To obtain PET of diagnostic quality, a sufficient amount radioactive tracer has to be injected into living body, which will inevitably increase the risk radiation exposure. On other hand, if dose is considerably reduced, quality resulting would significantly degraded. It great interest estimate standard-dose (S-PET) image from low-dose one order...

<title>Abstract</title> Natural thymoquinone has been extensively used as a chemopreventive agent and shown potent anticarcinogenic activity against broad range of human malignancies. However, the underlying mechanisms involving signaling pathways are still not well studies. Therefore, this study is aimed to evaluate effects on increasing doxorubicin chemosensitivity via targeting P21 PI3K/AKT signaling. Caco-2 cells were treated with thymoquinone. MTT assay applied assess impact different...

Bladder cancer is a common malignant tumor of the urinary tract as well one most cancers worldwide. Therefore, study key molecular targets involved in bladder carcinogenesis and progression crucial for prognosis cancer. Our aims to investigate mechanism by which cytokeratin 17 induces epithelial-mesenchymal transition promotes progression. In this study, 78 tissue specimens were collected, expression level (CK17) paracancerous tissues was detected immunohistochemistry, relationship between...

Abstract This study was conducted to investigate the antioxidant, antibacterial, and antiproliferative activities of flesh free (FF), bound (FB), peel (PF), (PB) phenolics from Fuji apple. The PB, which had highest total phenolic contents (126.15 ± 2.41 mg/100 g wet weight) lowest carbohydrate (34.68 2.78 weight), showed strongest 2,2’‐azinobis‐(3‐ethylbenthiazoline‐6‐sulphonate) (ABTS) radical scavenging activity (EC 50 = 0.36 0.02 mg/mL), 1,1‐diphenyl‐2‐picryhydrazyl (DPPH) 0.26 0.01...

Autoimmune thyroiditis (AIT), also known as Hashimoto's (HT), is an autoimmune disease that characterised by elevated thyroid-specific antibody titres. The incidence of AIT increasing year over year, making it urgent to establish a suitable animal model for this condition, in order better explore its pathogenesis and potential pharmaceutical mechanisms treatment. Owing lack basic research on disease, problems such disparate modelling methods with unclear varying success rates make difficult...

Abstract Progressive cardiac remodeling, including the myopathic process in adjacent zone following myocardial infarction (MI), contributes greatly to development of failure. Cardiomyoplasty using bone marrow-derived mesenchymal stem cells (MSCs) has been demonstrated protect cardiomyocytes and/or repair damaged myocardium, leading improved performance, but therapeutic effects on remodeling are still under investigation. Here, we tested hypothesis that MSCs could improve pathological...

Whether the alternated microbiota in gut contribute to risk of allograft rejection (AR) and pulmonary infection (PI) setting lung transplant recipients (LTRs) remains unexplored. A prospective multicenter cohort LTRs was identified four centers. Paired fecal serum specimens were collected divided into AR, PI, event-free (EF) groups according diagnosis at sampling. Fecal samples determined by metagenomic sequencing. And metabolites cytokines detected paired analyze potential effect altered...

Abstract BACKGROUND Carboxymethylpachymaran (CMP) is created by carboxymethylating pachyman (PM), which increases its water solubility and enhances a number of biological activities. Traditional polysaccharides modified carboxymethylation employ strong chemical techniques. Carboxymethylcellulose (CMC) has been used previously for liquid fermentation to carboxymethyl modify bacterial polysaccharides. This theory can be applied fungal because Poria cocos the ability naturally utilize...

Abstract Ionising radiation exposure can lead to acute haematopoietic syndrome. Despite significant advancements in the field of radioprotection, no drugs with high efficacy and low toxicity have yet been approved by Food Drug Administration. FG‐4592, as a proline hydroxylase inhibitor, may play an important role radioprotection system. Mice were peritoneal injected FG‐4592 or normal saline.
