Objective: To analyze the predictive value of the triglyceride-glucose (TyG) index and neutrophil-to-high-density lipoprotein ratio (NHR) for in-hospital major adverse cardiac events (MACE) after percutaneous coronary intervention (PCI) in patients with acute ST-segment elevation myocardial infarction (STEMI), and to establish an associated nomogram model.

Methods: In this retrospective study, we collected data from consecutive STEMI patients who underwent PCI from October 2019 to June 2023 at the Second People's Hospital of Hefei and the Second Affiliated Hospital of Anhui Medical University, as training and validation sets. Stepwise regression and multivariate logistic regression analysis were performed to screen independent risk factors, and a nomogram model was constructed and evaluated for its predictive efficacy.

Coal moisture content monitoring plays an important role in carbon reduction and clean energy decisions of coal transportation-storage aspects. Traditional coal moisture content detection mechanisms rely heavily on detection equipment, which can be expensive or difficult to deploy under field conditions. To achieve fast prediction of coal moisture content, a novel neural network model based on attention mechanism and bidirectional ResNet-LSTM structure (ABRM) is proposed in this paper.

Unraveling the genetic basis of medicinal plant metabolism and developmental traits is a long-standing goal for pharmacologists and plant biologists. This paper discusses the definition of molecular genetics of medicinal plants, which is an integrative discipline with medicinal plants as the research object. This discipline focuses on the heredity and variation of medicinal plants, and elucidates the relationship between the key traits of medicinal plants(active compounds, yield, resistance, etc.

Article Synopsis
  • The study focuses on the role of PYL proteins, which are receptors for abscisic acid (ABA), in the drought-tolerant plant Glycyrrhiza uralensis, known for its medicinal properties.
  • Researchers identified 10 different PYL proteins in G. uralensis and found that they are conserved, meaning they have similar structures and functions across the species.
  • The expression levels of these PYL proteins change in response to ABA stress, with specific genes (GuPYL4, GuPYL5, GuPYL8, GuPYL9) showing significant up-regulation, suggesting their importance in regulating secondary metabolites and improving cultivation methods.*

Article Synopsis
  • Camptotheca acuminata produces camptothecin (CPT), an important compound used for treating various cancers, and the study focuses on understanding how its biosynthesis is regulated by specific transcription factors called AP2/ERF.
  • A total of 198 AP2/ERF genes were identified in C. acuminata and classified into five subfamilies, with different expression patterns observed in various tissues.
  • The study highlights eight specific AP2/ERF transcription factors that may regulate CPT synthesis, particularly in the upper stem and immature bark, providing a basis for future research on enhancing CPT production.

The transcription factor Woolly (Wo) and its downstream gene CycB2 have been shown to regulate trichome development in tomato (Solanum lycopersicum). It has been demonstrated that only the gain-of-function allele of Slwo (SlWoV, the Slwo woolly motif mutant allele) can increase the trichome density; however, it remains unclear why the two alleles function differently in trichome development. In this study, we used Nicotiana benthamiana as a model and cloned the homologues of Slwo and SlCycB2 (named Nbwo and NbCycB2).

Pancreatic cancer is one of the most difficult clinical cases to diagnose with a very low 5-year survival rate of 5%, regardless of the advances made in both the medical and surgical treatment of the disease. One of the contributing factors for the high mortality rate seen of pancreatic cancer patients is the lack of effective chemotherapies, which is believed to be due to drug-resistance. Based on recent evidence, epithelial-mesenchymal transition (ETM) of pancreatic cancer cells has been found to be associated with the development of drug resistance and an increase in cell invasion.

As a co-receptor for a variety of cytokines, neuropilin-1 (NRP-1) is detectable in primary liver cancer (PLC) cells. Previous studies determined that silencing of NRP-1 expression attenuated the proliferation, migration and invasion of PLC cells. An increasing number of studies have highlighted the crucial role of the tumor microenvironment in the pathogenesis of cancer.

Article Synopsis
  • - The study sequenced the complete chloroplast genomes of two hemiparasitic plants, Taxillus chinensis and T. sutchuenensis, marking the first genomic analysis of this family, Loranthaceae.
  • - The chloroplast genomes were found to be circular, measuring 121,363 bp and 122,562 bp, and showed significant gene loss compared to other plants, including ndh genes and various ribosomal protein and tRNA genes.
  • - Phylogenetic analysis confirmed Loranthaceae and Viscaceae as distinct monophyletic groups, highlighting how a parasitic lifestyle impacts chloroplast structure and genome content, while also addressing differences in sequencing outcomes from Illumina and PacBio technologies. *

  • Grazing disturbance affects plant traits, influencing how well plants adapt to their environment.
  • In a study of Stipa krylovii steppe in Hulunbuir, different grazing intensities were analyzed, revealing that while life-form functional groups showed no significant trait differences, their traits were closely correlated.
  • Heavy grazing significantly altered leaf phosphorus content and nitrogen-to-phosphorus ratios in perennial forbs, indicating they are particularly sensitive to grazing, and appropriate grazing practices could enhance plant nutrient traits and reduce degradation in the steppe.

Background: Quantitative real-time reverse transcription PCR (qRT-PCR) requires a stable internal control to avoid misinterpretation of data or errors for gene expression normalization. However, there are still no validated reference genes for stable internal control in Poria cocos (Schw.) Wolf (Fuling).

Quantitative real-time reverse transcription PCR (qRT-PCR) is a rapid, sensitive, and reliable technique for gene expression studies. The accuracy and reliability of qRT-PCR results depend on the stability of the reference genes used for gene normalization. Therefore, a systematic process of reference gene evaluation is needed.
