[Mining, characterization, and expression of a fructan sucrase for efficient conversion of soybean oligosaccharides].

The high content of sucrose and raffinose reduces the prebiotic value of soybean oligosaccharides. Fructan sucrases can catalyze the conversion of sucrose and raffinose to high-value products such as fructooligosaccharides and melibiose. To obtain a fructan sucrase that can efficiently convert soybean oligosaccharides, we first mined the fructan sucrase gene from microorganisms in the coastal areas of Xisha Islands and Bohai Bay and then characterized the enzymatic and catalytic properties of the enzyme.

Soft Wireless Passive Chipless Sensors for Biological Applications: A Review.

Soft wireless passive sensors have been applied in biological, engineering, and other fields due to their advantages in powerless supply and remote data transmission. External information is obtained by soft wireless passive sensors via the external coils based on electromagnetic induction. The purpose of this review paper is to outline the biological applications of soft wireless passive chipless sensors and provide a classification of wireless passive sensors and an overall explanation of the main work.

Total marrow irradiation as part of autologous stem cell transplantation for patients with multiple myeloma.

The efficacy and safety of total marrow irradiation (TMI) plus a reduced dose of melphalan as autologous stem cell transplantation (ASCT) preconditioning for multiple myeloma (MM) patients were evaluated. The 11 patients with MM had a median age of 57 (range: 46-75) years; six of them were at standard risk and five of them were at high risk based on the Mayo Stratification of Myeloma and Risk-adapted Therapy (mSMART) standard risk factors. Before ASCT, three patients achieved stringent complete response (sCR), two patients achieved complete remission (CR), and the rest of the patients had either partial response (PR) or progressive disease.

Emotional Influences on Remembering and Forgetting Explained by Frontal and Parietal Dynamics.

Based on item-method directed forgetting (DF) task, sixty participants were recruited to explore the influence of emotion (negative, neutral, and positive) on memory encoding processing. Behavioral results showed that participants were more successful at remembering negative pictures that needed to be forgotten, with both higher recognition rates and Pr values compared to neutral pictures. In the brain, parietal activities reflected preferential processing during negative picture viewing through enhanced late parietal positive potentials (LPP) relative to neutral ones.

The roles of IDH2 and glutathione metabolism in cetuximab resistance in head and neck squamous cell carcinoma investigated by metabolomics and transcriptomics.

Cetuximab resistance is a significant challenge in the treatment of head and neck squamous cell carcinoma (HNSCC). In this study, cetuximab-resistant HNSCC cell lines were established, and untargeted metabolomics was used to detect differences in metabolite profiles between sensitive and resistant cell lines. It was found that glutathione metabolism significantly differed between the sensitive and resistant lines.
