miR-340-3p-modified bone marrow mesenchymal stem cell-derived exosomes inhibit ferroptosis through METTL3-mediated mA modification of HMOX1 to promote recovery of injured rat uterus.

Background: Ferroptosis is associated with the pathological progression of hemorrhagic injury and ischemia-reperfusion injury. According to our previous study, exosomes formed through bone marrow mesenchymal stem cells modified with miR-340-3p (MB-exos) can restore damaged endometrium. However, the involvement of ferroptosis in endometrial injury and the effect of MB-exos on ferroptosis remain elusive.

Single-cell transcriptomic profiling unveils insights into ovarian fibrosis in obese mice.

Background: Adiposity profoundly impacts reproductive health in both humans and animals. However, the precise subpopulations contributing to infertility under obese conditions remain elusive.

Results: In this study, we established an obese mouse model through an eighteen-week high-fat diet regimen in adult female mice.

Effect of inoculating thermophilic bacterial consortia on compost efficiency and quality.

The objective of this study was to investigate the potential effects of thermophilic bacterial consortia on compost efficiency and quality. The application of bacterial consortia resulted in an earlier onset of the thermophilic period (THP), an increased upper temperature limit, and an extended duration of the THP by 3-5 days compared to the control group (CK). Microbial inoculation significantly improved the efficiency of organic matter degradation, as well as the content of water-soluble nitrogen (WSN) and humic acid-carbon (HAC).

Changes in soil microbial community composition and organic carbon fractions in an integrated rice-crayfish farming system in subtropical China.

Integrated rice-crayfish farming system is a highly efficient artificial ecosystem in which the rice (Oryza sativa) variety 'Jianzhen 2' is cultivated in waterlogged paddy fields along with crayfish (Procambarus clarkii). We investigated soil carbon fractions and microbial community structure by phospholipid fatty acids (PLFA) analysis in a 10-year field experiment using an integrated rice-crayfish (CR) model and a rice monoculture (MR) model at soil depths of 0-10 cm, 10-20 cm, 20-30 cm, and 30-40 cm. Compared with the MR model, the CR model had significantly more total organic carbon, particulate organic carbon, and dissolved organic carbon contents in all of the layers examined and microbial biomass carbon content in the 20-40 cm layer.

[Nutrient spatial variability of tobacco soil restoration area and fertility suitability level evaluation].

By using geographic information system technology (GIS) and geostatistics methods, this paper studied the spatial variability of soil properties and available nutrients in the new regulation area units located in Qingjiangyuan modern tobacco agriculture science and technology park (Enshi, Hubei), suburb of Enshi City and the Baiyang base of Lichuan City, and further evaluation of the soil fertility suitability index (SFI) was carried out by use fuzzy mathematics. The results indicated that the effects of land restoration on the soil available phosphorus content variability and spatial distribution were very obvious, possibly due to the landform characteristics and restoration extent. The effect of land restoration on soil pH was small, however, serious soil acidification was detected in the soil sampled from Baiyang (pH < 5.

Phytotoxicity analysis of extracts from compost and their ability to inhibit soil-borne pathogenic fungi and reduce root-knot nematodes.

Compost extracts are novel organic amendments, typically applied to suppress soil-borne diseases. This research evaluated the phytotoxicity of compost extracts and analyzed their ability to inhibit pathogenic fungal growth and reduce root-knot nematodes. The physical, chemical and biological characteristics of extracts from a pig manure and straw compost were analyzed.

[Responses of rice-wheat rotation system in south Jiangsu to organic-inorganic compound fertilizers].

In 2006-2007, a field trial was conducted to study the effects of applying three kinds of organic-inorganic compound fertilizers [rapeseed cake compost plus inorganic fertilizers (RCC), pig manure compost plus inorganic fertilizers (PMC), and Chinese medicine residues plus inorganic fertilizers (CMC)] on the crop growth and nitrogen (N) use efficiency of rice-wheat rotation system in South Jiangsu. Grain yield of wheat and rice in the different fertilization treatments was significantly higher than the control (no fertilization). In treatments RCC, PMC and CMC, the wheat yield was 13.

Changes in biochemical and microbiological parameters during the period of rapid composting of dairy manure with rice chaff.

Various parameters were measured during the period of composting of dairy manure and rice chaff in different ratios (dairy manure/rice chaff=V/V, pile 1: 75/25; pile 2: 80/20; pile 3: 85/15) to evaluate their suitability as indicators for the composting process. The temperature in pile 1 increased rapidly and remained above 60 °C for 30 days, while the temperature in pile 3 increased slowly relative to the other two piles. Furthermore, the degradation of organic substrates, as indicated by the reduction of C/N ratio, was rapid in pile 1 (below 20% 28 days after beginning of the composting).

Transumbilical single-incision laparoscopic hepatectomy: an initial report.

Transumbilical single-incision laparoscopic surgeries have attracted the attention of surgeon. Here we report a patient with multiple hepatic hemagiomas and symptomatic cholelithiasis who underwent laparoscopic left lateral hepatecomy and left hepatic hemangioma enucleation with single incision followed by cholecystectomy. The duration of the operation was 155 minutes and the blood loss was 100 ml.

Different analysis techniques for fluorescence excitation-emission matrix spectroscopy to assess compost maturity.

Assessment of compost maturity is essential for achieving high quality compost. In this study, fluorescence excitation-emission matrix spectroscopy combined with different analysis techniques was applied to improve the sensitivity of compost maturity assessment. Results showed that composts in two parallel piles could be believed mature after 37d when combined with the evolution of temperature, chemical and biological indices in the two piles.
