Compost mediates the recruitment of core bacterial communities in alfalfa roots to enhance their productivity potential in saline-sodic soils.

Introduction: Composting is one of the effective environmental protection and sustainable measures for improving soil quality and increasing crop yield. However, due to the special physical and chemical properties of saline-sodic soil and the complex rhizosphere microecological environment, the potential mechanism of regulating plant growth after applying compost in saline-sodic soil remains elusive.

Methods: Here, we investigated the effects of different compost addition rates (0, 5, 15, 25%) on plant growth traits, soil chemical properties, and rhizosphere bacterial community structure.

Response of Alfalfa Leaf Traits and Rhizosphere Fungal Communities to Compost Application in Saline-Sodic Soil.

Soil salinization is considered a major global environmental problem due to its adverse effects on agricultural sustainability and production. Compost is an environmentally friendly and sustainable measure used for reclaiming saline-sodic soil. However, the responses of the physiological characteristics of alfalfa and the structure and function of rhizosphere fungal communities after compost application in saline-sodic soil remain elusive.

Optimization of saponin extraction from the leaves of and and evaluation of their antioxidant, antihypertensive, hypoglycemic and anti-inflammatory activities.

and are important economic plants that utilize dried roots for medicinal and food dual purposes; there is still insufficient research of their stems and leaves, which also contain triterpenoid saponins. The extraction process was developed with a total saponin content of 12.30 ± 0.

Transarterial Chemoembolization Combined with Tyrosine Kinase Inhibitors Plus Immune Checkpoint Inhibitors Versus Tyrosine Kinase Inhibitors Plus Immune Checkpoint Inhibitors in Unresectable Hepatocellular Carcinoma with First- or Lower-Order Portal Vein Tumor Thrombosis.

Purpose: To compare the efficacy of transarterial chemoembolization (TACE) combined with tyrosine kinase inhibitors (TKIs) plus immune checkpoint inhibitors (ICIs) (TACE-TKI-ICI) versus TKIs plus ICIs (TKI-ICI) for unresectable hepatocellular carcinoma (HCC) with first- or lower-order portal vein tumor thrombosis (PVTT).

Materials And Methods: A retrospective study was performed in HCC patients with first- or lower-order PVTT receiving TKIs (Lenvatinib or sorafenib) plus ICIs (camrelizumab, sintilimab, or atezolizumab) with or without TACE from four institutions between January 2019 and January 2022. Propensity score-based method was performed to minimize bias by confounding factors.

[Bacterial Community Diversity in Channel Sediments of Different Disturbance Sections of the Jialing River].

In order to explore the impact of different anthropogenic disturbances on the ecological environment of natural rivers, the bacterial community in the channel sediments of the Jialing River was taken as the research object, and the high-throughput sequencing technique was used to analyze the community composition and functional changes of bacteria in the channel sediments of rivers with engineering disturbance, tributary disturbance, sand mining disturbance, reclamation disturbance, and undisturbed section. The results showed that there were significant differences in the physical and chemical properties of channel sediments and bacterial community diversity in different disturbance sections of the Jialing River (<0.05).

Physiological and transcriptomic analyses reveal novel insights into the cultivar-specific response to alkaline stress in alfalfa (Medicago sativa L.).

Soil alkalization severely limits plant growth and development, however, the mechanisms of alkaline response in plants remain largely unknown. In this study, we performed physiological and transcriptomic analyses using two alfalfa cultivars (Medicago sativa L.) with different sensitivities to alkaline conditions.

A Multi-year Beneficial Effect of Seed Priming with Gibberellic Acid-3 (GA) on Plant Growth and Production in a Perennial Grass, Leymus chinensis.

Seed priming is a widely used technique in crops to obtain uniform germination and high-quality seedlings. In this study, we found a long-term effect of seed priming with gibberellic acid-3 (GA) on plant growth and production in Leymus chinensis. Seeds were germinated on agar plates containing 0-200 μM GA, and the germinated seedlings were transplanted to clay planting pots and grown for about one year.

Silicon Priming Created an Enhanced Tolerance in Alfalfa ( L.) Seedlings in Response to High Alkaline Stress.

Alkaline stress as a result of higher pH usually triggers more severe physiological damage to plants than that of saline stress with a neutral pH. In the present study, we demonstrated that silicon (Si) priming of alfalfa ( L.) seedlings increased their tolerance to high alkaline stress situations.

Root Damage under Alkaline Stress Is Associated with Reactive Oxygen Species Accumulation in Rice ( L.).

Alkaline stress (high pH) severely damages root cells, and consequently, inhibits rice ( L.) seedling growth. In this study, we demonstrate the accumulation of reactive oxygen species (ROS) in root cells under alkaline stress.

Stunted Growth Caused by Blast Disease in Rice Seedlings Is Associated with Changes in Phytohormone Signaling Pathways.

In response to pathogen attack, plants prioritize defense reactions generally at the expense of plant growth. In this work, we report that changes in phytohormone signaling pathways are associated with the stunted plant growth caused by blast disease in rice seedlings. Infection of rice seedlings with blast fungus (race 007.

Klebsiella pneumoniae invasive liver abscess syndrome with purulent meningitis and septic shock: A case from mainland China.

We present a rare case of invasive liver abscess syndrome due to Klebsiella pneumoniae (K. pneumoniae) with metastatic meningitis and septic shock. A previously healthy, 55-year-old female patient developed fever, liver abscess, septic shock, purulent meningitis and metastatic hydrocephalus.

Priming effect of abscisic acid on alkaline stress tolerance in rice (Oryza sativa L.) seedlings.

Saline-alkaline stress is characterized by high salinity and high alkalinity (high pH); alkaline stress has been shown to be the primary factor inhibiting rice seedling growth. In this study, we investigated the potential priming effect of abscisic acid (ABA) on tolerance of rice seedlings to alkaline stress simulated by Na2CO3. Seedlings were pretreated with ABA at concentrations of 0 (control), 10, and 50 μM by root-drench for 24 h and then transferred to a Na2CO3 solution that did not contain ABA.

Bimodal visualization of colorectal uptake of nanoparticles in dimethylhydrazine-treated mice.

Aim: To investigate colorectal uptake of solid lipid nanoparticles (SLNs) in mice receiving different doses of 1,2-dimethylhydrazine (DMH) using magnetic resonance (MR) and laser-scanning confocal fluorescence microscope (LSCFM) imaging.

Methods: Eight mice were sacrificed in a pilot study to establish the experimental protocol and to visualize colorectal uptake of SLNs in normal mice. Gadopentetate dimeglumine and fluorescein isothiocyanate (FITC)-loaded SLN (Gd-FITC-SLN) enemas were performed on mice receiving DMH for 10 wk (group 1, n = 9) or 16 wk (group 2, n = 7) and FITC-SLN enema was performed on 4 DMH-treated mice (group 3).

[Effects of storage conditions and sowing methods on seed germination of Leymus chinensis].

This paper studied the effects of four storage conditions (dry storage at 4 degrees C, dry storage at room temperature, storage in moist non-saline-alkali soil at 4 degrees C, and storage in moist saline-alkali soil at 4 degrees C), three germination substrates (filter paper, non-saline-alkali soil, and saline-alkali soil), and two sowing methods (sowing on and in the substrates) on the seed germination of Leymus chinensis. The results showed that compared with the dry storage at room temperature, dry storage at 4 degrees C improved the germination velocity significantly, but had less effect on germination rate. When stored in moist saline-alkali soil, the germination rate was only 28.
