The sequence of the circulations of the twelve meridians does not follow on the permutation of the yin and yang meridians,whereas it is based on the law of qi-blood circulation. The relative strength of circulation between yin and yang, the ebb and flow of qi-blood goes around and around as cycles. Yin, yang and qi-blood gather in the meridians of the Taiyin and the Yangming, mutually converting in maximum, passing the meridians of the Shaoyin and the Taiyang, and then reaching the meridians of the Jueyin and the Shaoyang in minimum. It reflects not only the running course of the meridians, the sequential and reverse transmission, but also reflects the mutual supporting of yin-yang, and waxing and waning of yin-yang, the relative equilibrium of qi-blood, the transformation of excess and deficiency of disease. Therefore, the clear inspection of the law of qi-blood circulations of the twelve meridians, which is based on the therapy, is the precondition of the comprehensive significance of the sequence.

For commercial laying hens, the continuous high-intensity ovulation process leads to a significant accumulation of reactive oxygen species (ROS) in the granulosa cells, inducing oxidative stress, which accelerates ovarian aging and shortens the peak laying period. The molecular mechanisms underlying this process remain poorly understood. Therefore, we modeled the processes of oxidative stress and antioxidant in chicken granulosa cells.

CDK4/6 inhibitors are effective in treating HR/HER2 breast cancer but face limitations due to therapeutic resistance and hematological toxicity, particularly from strong CDK6 inhibition. To address these challenges, designing selective inhibitors targeting specific cyclin-dependent kinases (CDK) members could offer clinical advantages and broaden CDK inhibitor indications. However, the highly conserved binding pockets of CDKs complicate selective targeting.

Background: To analyze the demographic characteristics of retinopathy of prematurity (ROP) in China, attempting to propose optimized screening criteria and hopefully providing valuable information for future updates to the ROP guideline.
Methods: A multicenter, retrospective-cohort study was conducted. The study included infants born between January 1, 2018, and July 31, 2023, who underwent ROP screening and were diagnosed with ROP at seven screening centers in China.

Inflammation is a driving force of hematopoietic stem cells (HSCs) aging, causing irreversible exhaustion of functional HSCs. However, the underlying mechanism of HSCs erosion by inflammatory insult remains poorly understood. Here, we find that transient LPS exposure primes aged HSCs to undergo accelerated differentiation at the expense of self-renewal, leading to depletion of HSCs.

Plant cuticular waxes serve as highly responsive adaptations to variable environments. Aliphatic waxes consist of very-long-chain (VLC) compounds produced from 1-alcohol- or alkane-forming pathways. The existing variation in 1-alcohols and alkanes across Arabidopsis accessions revealed that 1-alcohol amounts are negatively correlated with aridity factors, whereas alkanes display the opposite behaviour.
