Microbubble enhanced ultrasound with low mechanical index promotes therapeutic angiogenesis in hind limb ischemia mouse model.

Background: Microbubble enhanced ultrasound (MEUS) can augment tissue perfusion by angiogenesis yet the best treatment ultrasound power in the initial ischemia period is uncertain.

Purpose: Considering the mechanical index (MI) is the most commonly used parameter for regulating diagnostic ultrasound power, here, we explored the effects of MEUS mediated by different MI on perfusion and sought to characterize the angiogenesis in the early stage of ischemia.

Methods: Experiments were conducted on hind limb ischemia mouse model (HLI) and MEUS was administrated in the first week every other day following induction of HLI for four times.

A predictive model of treatment effectiveness of refractory peritoneal dialysis-related peritonitis in patients with peritoneal dialysis: a single-center observational study in South China.

Background: To prevent loss of peritoneal function caused by persistent abdominal inflammation, the guidelines recommend early extubation in patients with refractory peritoneal dialysis (PD)-associated peritonitis (rPDAP). In attempt to pinpoint high-risk patient cohorts that did not respond to treatment for refractory peritonitis, we created a model to predict the effectiveness of peritonitis treatment.

Methods: This observational cohort study included PD patients from 1 January 2011 to 31 December 2020.

Accurate Coal Classification Using PAIPSO-ELM with Near-Infrared Reflectance Spectroscopy.

China has vast proven coal reserves, encompassing a wide variety of types.

Predicting risk factors for postoperative intestinal stenosis in neonates with necrotizing enterocolitis: development and assessment of a predictive nomogram.

Objective: The aim of this study was to develop and validate an intestinal stenosis prediction model for postoperative newborns with neonatal necrotizing enterocolitis (NEC).

Advancement on target ranging and tracking by four-quadrant photon counting lidar.

Single-photon lidar stands out as a promising technology for long-distance lidar applications, owing to its attributes of single-photon sensitivity and high repetition rate. Existing single-photon lidar systems typically rely on single-point scanning for positioning and tracking, necessitating intricate and precise scanning control. In pursuit of a more concise and efficient positioning, we incorporate the four-quadrant theory to articulate the signal formula of photon detection, and propose a novel single-photon four-quadrant positioning method.

A Novel Ah-miR2916-AhERF13-AhSUC3 Module Regulates Al Tolerance via Ethylene-Mediated Signaling in Peanut (Arachnis hypogea L).

Aluminum (Al) toxicity in acidic soils leads to a considerable reduction in crop yields. MicroRNAs play essential roles in abiotic stress responses, but little is known of their role in the response of peanut (Arachnis hypogea L.) to Al stress.

TRX h2-PP2AC2 module serves as a convergence node for aluminum stress and leaf senescence signals, regulating cell death via ABA-mediated ROS pathway.

ROS/redox signaling plays an important role in the regulation of signal transduction and acclimation pathways activated by multiple abiotic stresses and leaf senescence. However, the regulatory events that produce ROS under different stimuli are far from clear. Here, we report the elucidation of the molecular mechanism of an h type thioredoxin, AhTRX h2, positively regulates Al sensitivity and leaf senescence by promoting ROS.

Haizao-Gancao herb pair ameliorates propylthiouracil-induced goiter by regulating the Beclin1-mediated autophagy.

Ethnopharmacological Relevance: Haizao, Sargassum, is widely used to treat goiter. Gancao, Glycyrrhizae radix et rhizome, is renowned for reducing toxicity or increasing effects in traditional Chinese medicine. As a classic herb pair, Haizao-Gancao (HG) is a commonly used and effective combined therapy for goiter.

Knockdown of Adenosine 5'-Triphosphate-Dependent Caseinolytic Protease Proteolytic Subunit 6 Enhances Aluminum Tolerance in Peanut Plants ( L.).

Aluminum (Al) toxicity in acidic soils reduces root growth and can lead to a considerable reduction in peanut plants ( L.). The caseinolytic protease (Clp) system plays the key role in abiotic stress response.

AhGSNOR1 negatively regulates Al-induced programmed cell death by regulating intracellular NO and redox levels.

The toxicity of aluminum (Al) in acidic soil inhibits plant development and reduces crop yields. Programmed cell death (PCD) is one of the important mechanisms in the plant response to Al toxicity. However, it is yet unknown if S-nitrosoglutathione reductase (GSNOR) provides Al-PCD.

miR-96-5p expression is sufficient to induce and maintain the senescent cell fate in the absence of stress.

Senescence is a cell fate driven by different types of stress that results in exit from the cell cycle and expression of an inflammatory senescence-associated secretory phenotype (SASP). Here, we demonstrate that stable overexpression of miR-96-5p was sufficient to induce cellular senescence in the absence of genotoxic stress, inducing expression of certain markers of early senescence including SASP factors while repressing markers of deep senescence including LINE-1 and type 1 interferons. Stable miR-96-5p overexpression led to genome-wide changes in heterochromatin followed by epigenetic activation of p16, p21, and SASP expression, induction of a marker of DNA damage, and induction of a transcriptional signature similar to other senescent lung and endothelial cell types.

TREM2 macrophages mediate the beneficial effects of bariatric surgery against MASH.

Background And Aims: For patients with obesity and metabolic syndrome, bariatric procedures such as vertical sleeve gastrectomy (VSG) have a clear benefit in ameliorating metabolic dysfunction-associated steatohepatitis (MASH). While the effects of bariatric surgeries have been mainly attributed to nutrient restriction and malabsorption, whether immuno-modulatory mechanisms are involved remains unclear.

Approach And Result: Using murine models, we report that VSG ameliorates MASH progression in a weight loss-independent manner.

Chromosome-level assembly of and comparative genomic analyses shed light on genome evolution in Lamiales.

Lamiales, comprising over 23,755 species across 24 families, stands as a highly diverse and prolific plant group, playing a significant role in the cultivation of horticultural, ornamental, and medicinal plant varieties. Whole-genome duplication (WGD) and its subsequent post-polyploid diploidization (PPD) process represent the most drastic type of karyotype evolution, injecting significant potential for promoting the diversity of this lineage. However, polyploidization histories, as well as genome and subgenome fractionation following WGD events in Lamiales species, are still not well investigated.

Lightweight single-phase Al-based complex concentrated alloy with high specific strength.

Developing light yet strong aluminum (Al)-based alloys has been attracting unremitting efforts due to the soaring demand for energy-efficient structural materials.

Here, we propose to surmount this challenge by converting multiple brittle phases into a ductile solid solution in Al-based complex concentrated alloys (CCA) by applying high pressure and temperature.
