Exposure to greenspaces sourced soils improves mice gut microbiota.

Greenspaces are important components of our living environment and have been linked to various human health. However, the mechanisms underlying the linkages remain unclear. Enriching microbiota has emerged as a novel mechanism, but the corresponding evidence is still limited.

Ubiquitin ligase TRIM32 promotes dendrite arborization by mediating degradation of the epigenetic factor CDYL.

Proper dendritic morphology is fundamental to nerve signal transmission; thus, revealing the mechanism by which dendrite arborization is regulated is of great significance. Our previous studies have found that the epigenetic molecule chromodomain Y-like (CDYL) negatively regulates dendritic branching. Current research mostly focuses on the processes downstream of CDYL, whereas the upstream regulatory process has not been investigated to date.

[Comparative analysis and comprehensive evaluation for growth and photosynthetic characteristics of different lily species and varieties].

The biological characteristics,agronomic traits,yield traits,stress resistance,quality and photosynthetic characteristics among six lily varieties were compared in order to screen out the excellent lily varieties suitable for spread planting in Hunan province. Lilium longiflorum had the longest growth period,246 days,among these six lily varieties,while others were about 170 days. The leaves of L.

Triterpenoids from stems of Kadsura heteroclita.

In the present work, we reported the triterpenoids isolated from n-butanol fraction of Kadsura heteroclita which is a Tujia ethnomedicine with trivial name "Xuetong". This effort resulted in the isolation of six unpresented triterpenoids xuetongsu A-F (1-6), along with five known triterpenoids (7-11). The structures of the reported compounds were established on the 1D, and 2D NMR and HRESIMS spectra, along with CD spectroscopic analysis.

Investigation and Modeling of Capacitive Human Body Communication.

This paper presents a systematic investigation of the capacitive human body communication (HBC). The measurement of HBC channels is performed using a novel battery-powered system to eliminate the effects of baluns, cables and instruments. To verify the measured results, a numerical model incorporating the entire HBC system is established.

[Molecular identification of Mentha haplocalyx and Mentha spicata with specific primers multi-PCR system].

Objective: To screen specific SNPs loci of Mentha haplocalyx and Mentha spicata,and then specific primers were designed to identify the two species and their mixture rapidly.

Methods: PsbA-trnH sequences of Mentha haplocalyx and Mentha spicata were obtained by PCR product sequencing and downloading from GenBank. SNPs in the psbA-trnH sequences of Mentha haplocalyx and Mentha spicata were found by ClustulW program and Bioedit software.

[Preliminary study on research method of cell survival rate at procedure of cryopreservation of tissue engineered tendons].

Objective: To study the research method of cell survival rate at the procedure of cryopreservation of tissue engineered tendons.

Methods: In the 4th generation of human fibroblasts, the dead cells were stained with propidium iodine (PI), while the living cells with Hoechst 33342 (Ho). The living cells and dead cells emitted fluorescence of red and blue respectively after they were stimulated by suitable ultra-violet, then flow cytometry was applied to distinguish them.
