Formulation of a novel hot pot dipping sauce enriched with pepper seed press cake: Physical properties and flavor characteristics.

Novel hot pot dipping sauces enriched with pepper seed press cake (PSPC) in five proportions were prepared and evaluated in terms of their physical properties and flavor characteristics. The findings indicated that enriching the sauce increased the content of palmitic and linoleic acids, enhanced storage stability, and improved the rheological behavior and textural properties. The maximum concentration of N-heterocyclic compounds was detected when PSPC was added at 5 g/100 g and 10 g/100 g.

[Bacterial Community Structure of Typical Lake Sediments in Yinchuan City and Its Response to Heavy Metals].

Lake wetlands are extremely important and special ecosystems, which are important for regional water resource storage, environmental protection, and biodiversity maintenance. Sediment bacteria are an important component of lake ecosystems and are a major driver of biogeochemical cycling in lakes. In order to investigate the community structure of bacteria in typical lake sediments in Yinchuan City and their influencing factors, three typical lakes in Yinchuan City (Yuehai Lake, Mingcui Lake, and Xiniu Lake) were selected for the study and surface sediments were collected in January, April, July, and October 2021.

[Effect of telomerase activation on biological behaviors of neural stem cells in rats with hypoxic-ischemic insults].

Objective: To investigate the effect of telomerase activation on biological behaviors of neural stem cells after hypoxic-ischemic insults.

Methods: The neural stem cells passaged in vitro were divided into four groups: control, oxygen-glucose deprivation (OGD), OGD+cycloastragenol (CAG) high concentration (final concentration of 25 μM), and OGD+CAG low concentration (final concentration of 10 μM). The latter three groups were subjected to OGD.

[Construction of prokaryotic expression vector for Ag85A-HA2 fusion gene and studies on the immunity efficacy of fusion protein against influenza A virus].

Objective: To construct Ag85A-HA2 prokaryotic expression vector, express the fusion protein and study the immunity efficacy of fusion protein against influenza A virus.

Methods: Ag85A-HA2 prokaryotic expression vector was constructed and induced with IPTG. The fusion protein was identified by SDS-PAGE and purified with His-Tag affinity chromatography.
