Intramolecular Hosomi-Sakurai Reaction for the Synthesis of Benzoxasiloles.

A Lewis acid-catalyzed intramolecular Hosomi-Sakurai reaction of -(allylsilyl)benzaldehyde/ketone has been developed. The reaction proceeds through simultaneous C-Si bond cleavage and C-C bond reconstruction. This protocol provides a rapid approach for the synthesis of allyl-substituted benzoxasiloles under mild conditions.

Community structure of endophytic bacteria of Sargassum thubergii in the intertidal zone of Qingdao in China.

Endophytic bacteria are one of the symbiotic microbial groups closely related to host algae. However, less research on the endophytic bacteria of marine algae. In this study, the endophytic bacterial community of Sargassum thunbergii was investigated using the culture method and high-throughput sequencing.

The host sex contributes to the endophytic bacterial community in and their receptacles.

Endophytic bacteria have a complex coevolutionary relationship with their host macroalgae. Dioecious macroalgae are important producers in marine ecosystems, but there is still a lack of research on how sex influences their endophytic bacteria. In this study, the endophytic bacterial communities in male and female and their reproductive tissues (receptacles) were compared using culture methods and high-throughput sequencing.

Genome-Wide Identification and Analysis of Receptor-like Kinase 1-like Proteins in Eggplant.

As an important member of the plant receptor-like kinases, receptor-like kinase 1-like (CrRLK1L) plays vital roles in plant growth and development, as well as biotic and abiotic stress response. Numerous CrRLK1Ls have been identified and analyzed in various plant species, while our knowledge about eggplant ( L.) CrRLK1Ls is still scarce.

Microbial metabolism and humic acid formation in response to enhanced copper and zinc passivation during composting of wine grape pomace and pig manure.

Copper (Cu) and zinc (Zn) in piglet feed can lead to heavy metals (HMs) accumulation in pig manure (PM). Composting is crucial for recycling biowaste and decreasing HMs bioavailability. This study aimed to investigate the impact of adding wine grape pomace (WGP) on the bioavailability of HMs during PM composting.

Genome-Wide Re-Identification and Analysis of CrRLK1Ls in Tomato.

The receptor-like kinase 1-like (CrRLK1L), which is a vital member of the plant receptor-like kinase family, plays versatile roles in plant growth, development, and stress response. Although the primary screening of tomato CrRLK1Ls has been reported previously, our knowledge of these proteins is still scarce. Using the latest genomic data annotations, a genome-wide re-identification and analysis of the CrRLK1Ls in tomatoes were conducted.

Sex plays a role in the construction of epiphytic bacterial communities on the algal bodies and receptacles of .

The community structures of epiphytic bacteria on the surface of macroalgae are closely related to their host algae, but there is a lack of research on the differences between the epiphytic bacterial communities of male and female algae and their reproductive tissues. In this study, high-throughput sequencing was used to compare epiphytic bacterial community structures on the intertidal macroalgae and their receptacles between male and female samples. The epiphytic bacteria on the male and female algal bodies and receptacles had similar community structures with a large number of shared bacteria, but the samples clearly clustered separately, and the abundances of dominant taxa, specific bacteria, and indicator species differed, indicating that epiphytic bacterial communities differed significantly between the male and female and their receptacles.

Peak-to-peak standard deviation based bubble detection method in sodium flow with electromagnetic vortex flowmeter.

The steam generator (SG) is a heat exchange device between a sodium coolant and water in sodium-cooled fast reactors. Its transfer tubes are prone to leakage to result in sodium-water reaction, which will affect the operational safety of the entire nuclear reactor. To this end, a signal processing method is studied to detect the SG leakage using an electromagnetic vortex flowmeter (EVFM).

Transient process based electromagnetic flow measurement methods and implementation.

The ordinary electromagnetic flowmeter (EMF) utilizes the steady-state period of the excitation current for measuring the flow rate in order to ensure zero stability and measurement accuracy. In this paper, the transient process of EMF is studied to measure the flow rate so as to realize applications requiring ultra-low power consumption, for example, water meters. For this reason, the dynamic excitation current and signal voltage of the transient process are analyzed, and three kinds of transient measurement methods are proposed to determine the relationship between the processing results of the signal voltage and flow rates.

[Expression of Nerve Growth Factor and Type 3 of Acid Sensitive Ion Channels in Rat Model of Type Ⅲ Prostatitis].

Objective: To investigate the expressions of nerve growth factor (NGF) and acid-sensing ion channel 3 (ASIC3) in prostatic tissue of experimental rats with type Ⅲ prostatitis.

Methods: Thirty SD rats were randomly allocated into control group and experimental group. The rats in control group were subjected to pelvic and bilateral scapular subcutaneous injections of 0.

Bacteriophage T4 nanoparticle capsid surface SOC and HOC bipartite display with enhanced classical swine fever virus immunogenicity: a powerful immunological approach.

The phage T4 HOC, SOC bipartite display system is attractive for the expression of cDNA and display of peptides or proteins at high copy numbers on the phage capsid surface. Until recently, using T4 phage vector to display large foreign molecular immunogens resulted only from either an SOC or HOC single site. In this report, the main advantages of the phage T4 system over other display technologies are substantiated by using the phage T4 SOC, HOC dual site display vector T4-Zh(-) to express: (1) on the SOC site, the classical swine fever virus (CSFV) major antigenic determinant cluster mE2 (123 amino acid, aa) through gene fusion to the SOC gene C-terminus of T4 genome, and (2) on the HOC site, full-length CSFV primary antigen E2 (371 aa) through a co-transformed plasmid, hence leading to a simultaneous display of both proteins on the T4 capsid surface.
