Protein tyrosine phosphatase 1B (PTP1B) has been identified as a key drug target for anti-tumor drug development. Oleanolic acid (OA) has been proved to be an inhibitor of PTP1B, but its poor water solubility, low bioavailability and poor activity in vivo limit its clinical efficacy. In this study, a total of 47 new OA derivatives including heteroatom derivatives, ester derivatives, amino substitution derivatives and Schiff base derivatives were designed and synthesized.

Ginsenoside CK, a metabolite of diol ginsenosides, have many excellent pharmacological activities, but whether ginsenoside CK can overcome gefitinib resistance remains unclear. In our study, the sensitizing activity of ginsenoside CK on gefitinib-resistant non-small cell lung cancer (NSCLC) in vitro and in vivo was investigated.

Methods: We retrospectively analyzed 201 DLBCL patients who underwent pre-treatment abdominal CT examination. CT images were used to assess body composition metrics at the third lumbar vertebrae including fat tissues and muscle.
To gradually reduce the demand for fossil energy and accelerate energy transformation, alcohol fuels are being vigorously developed and utilized in the world. -Pentanol as a common alcohol fuel has attracted increasing attention in recent years owing to its many advantages. In this study, a reduced mechanism of -pentanol containing 148 species and 575 reactions was established based on combined reduction methods including the direct relationship graph with error propagation, reaction pathway analysis, rate of production analysis, and temperature sensitivity analysis methods.

Chimeric antigen receptor (CAR) T-cell immunotherapy is a new type of immunotherapy that uses genetic engineering techniques to modify and expand the patient's autoimmune cells , after which these cells are reinfused into the patient. CAR-T cell immunotherapy has the potential to treat different types of B-cell lymphoma.

We carried out a comprehensive literature search in four databases. Study endpoints, hazard ratios (HRs) and the associated 95% confidence intervals (CI) for clinical outcomes, which were to assess therapeutic efficacy, were extracted.

However, millet straw is a potential alternative resource for Agaricus bisporus cultivation, but this has hardly been studied. In the present study, the feasibility of millet straw based mushroom production was analyzed by three successive trials.

Therefore, rapid and sensitive detection methods should be developed to present timely warning of harmful algal blooms. In this study, hyperbranched rolling circle amplification (HRCA) was established for the detection of H.

Effective and affordable, antibacterial and hemostatic materials are of great interests in clinical wound care practices. Herein, Enterobacteria phage T4 were incorporated in polycaprolactone/collagen I (PCL-ColI) nanofibers via electrospinning in order to eradicate Escherichia coli infection and meanwhile establish hemostasis. Tensile strength of the membrane was significantly enhanced with increased PCL ratio.

The results showed the collagen content was increased by 16.3% in UASC over the collagen from the conventional extraction (ASC).
View Article and Find Full Text PDFCollagen, one of the most biocompatible materials in nature, is widely used in wound healing and organ repair. However, the limited mechanical strength and biological effectiveness of collagen restrain its application as a hemostasis and filling material in medicine. To overcome these limitations, ultraporous collagen/oxidized regenerated cellulose (Col/ORC) composites were prepared.
