- Abstract:
- ... Garlic polysaccharide-Fe(III) complex (FePS) was synthesized by co-thermal synthesis with garlic polysaccharide (PS) and ferric trichloride. The complex was characterized by infrared spectroscopy and thermogravimetric analysis. The scavenging activity of PS and FePS on hydroxyl radicals, superoxide anions and lipid peroxidation were studied. The scavenging hydroxyl radical activity of PS and FePS ...

- Abstract:
- ... One drug's pharmacological activity may be changed unexpectedly, owing to the concurrent administration of another drug. It is likely to cause unexpected drug-drug interactions (DDIs). Several machine learning approaches have been proposed to predict the occurrence of DDIs. However, existing approaches are almost dependent heavily on various drug-related features, which may incur noisy inductive b ...

- Abstract:
- ... Changes in ecological stoichiometry reflect nitrogen (N), phosphorus (P) and both N and P limitations in a plant community, which in turn affect plant diversity of the community. However, the relationship between plant community diversity and ecological stoichiometry has not yet been fully researched in arid and semi-arid regions. Ecological stoichiometry and plant community diversity indices of e ...

- Abstract:
- ... Sufficient dimension reduction is an important branch of dimension reduction, which includes variable selection and projection methods. Most of the sufficient dimension reduction methods are sensitive to outliers and heavy-tailed predictors, and require strict restrictions on the predictors and the response. In order to widen the applicability of sufficient dimension reduction, we propose BCov-SDR ...

However, traditional RSF-based materials can hardly be applied in 3D printing, which has shown great potential in producing artificial implants. In this work, we report a 3D printable RSF hydrogel formed by a weak, chemically crosslinked network. After the 3D printing process, the mechanical ...

- Abstract:

We propose a novel method of non-intrusive vibration sensing for rotating detonation mode recognition. The conventional method is intrusive and exposes the pressure sensor to the high-temperature and high-pressure detonation wave, which limits the sensor life. In the proposed method, the vibrat ...

However, the presence of polar groups results in poor water resistance and unsatisfactory bonding strength of protein-based adhesives, limiting their practical applications. In addition, the complicated preparation process also made the production of protein-based adhesive ...

Neuropeptides and endocannabinoids are neuronal signalling molecules that influence the functions of the whole brain. Endocannabinoids, enkephalin, substance P, neurotensin, orexin, somatostatin and pituitary adenylate cyclase-activating polypeptides are richly concentrated in the globus pallidus. Neuropeptide ...

Porcine sialoadhesin (poSn) has been previously shown to mediate PRRSV attachment and internalization. In the current study, we report its unidentified role in antagonism of type I interferon (IFN) production during PRRSV infection. We determined that poSn facilitated PRRSV infection v ...
