Article Synopsis
  • A study assessed risk factors for persistent airflow limitation (PAL) in children with asthma, aiming to create a prediction model for identifying those at high risk.
  • The study involved 2072 asthmatic children aged 5-16, classifying them into non-PAL, reversible PAL (RPAL), and irreversible PAL (IPAL) after two years of follow-up.
  • Findings revealed that asthma history and poor medication adherence increased the risk for RPAL, while higher BMI and pneumonia history were linked to IPAL; the developed prediction model showed strong ability to identify high-risk cases.

The pursuit of groundbreaking health care innovations has led to the convergence of artificial intelligence (AI) and traditional Chinese medicine (TCM), thus marking a new frontier that demonstrates the promise of combining the advantages of ancient healing practices with cutting-edge advancements in modern technology. TCM, which is a holistic medical system with >2000 years of empirical support, uses unique diagnostic methods such as inspection, auscultation and olfaction, inquiry, and palpation. AI is the simulation of human intelligence processes by machines, especially via computer systems.

Objective: Intestinal flora homeostasis in rats with type 2 diabetes mellitus (T2DM) was evaluated to explore the effects of total saponins (TAS) on hepatic insulin resistance (IR).

Methods: Six-week-old male Sprague-Dawley rats were fed high-fat and high-sugar diet for 4 weeks and intraperitoneally injected with streptozotocin to induce T2DM, and they were then randomly divided into control, model, metformin, and TAS groups. Stool, serum, colon, and liver samples were collected after 8 weeks of drug administration for relevant analyses.

As a distinctly different way from apoptosis, ferroptosis can cause cell death through excessive accumulation of lipid peroxide (LPO) and show great potential for cancer therapy. However, efficient strategies for ferroptosis therapy are still facing great challenges, mainly due to insufficient endogenous H O or relatively high pH value for Fenton reaction-dependent ferroptosis, and the high redox level of tumor cells attenuates the oxidation therapy. Herein, an efficient lipid-based delivery system to load oxidation catalyst and glutathione peroxidase 4 (Gpx4) inhibitor is orchestrated, intending to amplify Fenton reaction-independent ferroptosis by bidirectional regulation of LPO accumulation.

Article Synopsis
  • The paper discusses a new method for the phase transfer of a type of metal-organic framework, ZIF-90, between organic solvents and water using carbon monoxide (CO).
  • The mechanism involves creating hydrophilic ammonium salts through a reaction between CO and amines in ZIF-90, enabling this reversible transfer.
  • This approach allows for efficient coupling in esterification reactions, facilitates product separation, and supports component recycling, contributing to more sustainable chemical processes.

is a perennial genus that belongs to the tribe Triticeae (Poaceae) which has an adaptive capacity to ecological conditions and strong resistance to cold, drought, and salinity. Most species are fine herbs that can be used for agriculture, conservation, and landscaping. Due to confusion taxonomy within genera, the complete chloroplast (cp) genome of 13 species was sequenced, assembled, and compared with those of three other previously published species (, , and ) to clarify the issue.

The train sometimes needs to brake frequently on the turnout, although the braking force does not exceed the limit resistance of fastener, cumulative displacement of rail occurs because of the long-term effect of the train brakes, thus, the relationship between the cumulative displacement of rail and the number of train braking actions should be explored. Aiming at the spring bar type III fastener, a 1:1 physical indoor simulation test was carried out, and an electromagnetic relay device was used to simulate the train load, force, and displacement sensors for data collection. Then a single load no more than the maximum resistance of fastener was applied to the rail end to explore the relationship between the number of loads and the rail cumulative deformation.
