Study on R6-3 from Sayram Ketteki to prevent chronic unpredictable mild stress-induced depression in mice through the microbiota-gut-brain axis.

The prevention, mitigation and treatment of depression has become a global issue that needs to be solved urgently. Sayram Ketteki, a traditional natural fermented yoghurt from the region with the world's fourth highest life expectancy, has been known as the "longevity secret", whose longevity and anti-depression factors are speculated to come from its rich microorganisms. Therefore, for the first time, we systematically studied in depth the microbes of Sayram Ketteki, screened a new edible probiotic strain, R6-3, and explored its anti-depression effect in chronic unpredictable mild stress (CUMS)-induced depression in mice.

Dual-template hydrophilic imprinted resin as an adsorbent for highly selective simultaneous extraction and determination of multiple trace plant growth regulators in red wine samples.

In recent years, numerous plant growth regulators have been found in foods and have a toxicity to human health, so its simultaneous multiple monitoring is urgently. For the first time, a rapid, accurate, and high-selective method was established to extract and determine multiple plant growth regulators simultaneously in red wines using a new dual-template hydrophilic molecularly imprinted resin (DHMIR) as an adsorbent of pipette tip solid-phase extraction coupled with HPLC. The as-prepared DHMIR combined the advantages of the hydrophilicity of hydrophilic resin and multi-imprinted recognition of dual-template molecular imprinting, overcoming the poor imprinted recognition ability of traditional imprinting materials in water and low extraction efficiency to multiple targets.

The synthetic parameters of DZ@ZIF-8 were optimized, and the loading content of DZ was maximized.

Microbial regulation of nitrous oxide emissions from chloropicrin-fumigated soil amended with biochar.

The microbial mechanism underpinning biochar's ability to reduce emissions of the potent greenhouse gas nitrous oxide (NO) is little understood. We combined high-throughput gene sequencing with a dual-label N-O isotope to examine microbial mechanisms operative in biochar made from Crofton Weed (BC1) or pine wood pellets (BC2) and the NO emissions from those biochar materials when present in chloropicrin (CP)-fumigated soil. Both BC1 and BC2 reduced NO total emissions by 62.

Organic fertilizers activate soil enzyme activities and promote the recovery of soil beneficial microorganisms after dazomet fumigation.

Soil fumigation can reduce the impact of soil-borne diseases, weeds and insect pests on commercial crop production. Unfortunately, fumigation also kills beneficial microorganisms. In this study, we explored if dazomet fumigation could be used in combination with organic fertilizers (silicon fertilizer, potassium humate organic fertilizer, Bacillus microbial fertilizer, and mixtures of the last two) to reduce its impact on soil beneficial microorganisms.

The Review on the Role of Ambiguity of Tolerance and Resilience on Students' Engagement.

Due to the arrival of positive psychology (PP) in the development of teaching, the construct of engagement has been thrived and got a notable function in the educational arena. Alternatively, numerous individual differences, containing ambiguity of tolerance, have been taken into consideration as a result of the key role they can play in the process of learning, and thus, on different facets of the learners' engagement. Furthermore, resilience is recommended to be an alternate and effective way of engaging English as a foreign language (EFL) learners.
