Objective: To investigate the application value of pediatric sepsis-induced coagulation (pSIC) score and mean platelet volume/platelet count (MPV/PLT) ratio in the diagnosis of pediatric sepsis and the determination of critical pediatric sepsis.

Methods: A retrospective cohort study was conducted, selecting 112 children with sepsis (sepsis group) admitted to pediatric intensive care unit (PICU) of Liaocheng Second People's Hospital from January 2020 to December 2023 as the study objects, and 50 children without sepsis admitted to the pediatric surgery department of our hospital during the same period for elective surgery due to inguinal hernia as the control (control group). The children with sepsis were divided into two groups according to the pediatric critical case score (PCIS).

Parallel evolution of the same, or at least very similar, phenotype(s) in different lineages is often interpreted as evidence for the action of natural selection. However, caution is required when inferring parallel evolution based on uncertain or potentially incorrect phylogenetic frameworks. Here, by conducting extensive phylogenomic and population genetic analyses, we aim to clarify the evolutionary history of spurless taxa within the Aquilegia ecalcarata complex.

Article Synopsis
  • Organ shape in plants and animals usually develops during the early stages of growth, but some examples show that shapes can be altered later through reshaping processes, like in Capsella fruit.
  • Research reveals that the heart shape of Capsella fruits is created through specific changes in cell growth and division after fertilization, driven by a mechanism involving auxin and a crucial regulatory element.
  • This regulatory element, found in the promoter of the CrSTM gene, allows for a self-reinforcing loop that helps control the shape transformation of the fruit, indicating a shared molecular process across different species in the Brassicaceae family.

Objective: Alterations in gut microbiota have been implicated in the pathogenesis of ankylosing spondylitis (AS), but the underlying mechanisms remain elusive. This study aims to investigate changes in gut microbiota and metabolites in individuals with AS before and after treatment with secukinumab, to identify the biological characteristics specific to AS patients and investigate the potential biomarkers, for optimizing therapeutic strategies more effectively.

Methods: Fecal microbiome data were collected from 30 AS patients before and after secukinumab therapy and compared with data from 40 healthy controls (HC).

Article Synopsis
  • Living fossils are species that have undergone minimal changes over long periods, and this study focuses on the Eupteleaceae plant family to explore their molecular evolution.
  • By using advanced techniques in phylogenomics, comparative genomics, and ecological modeling, researchers created a detailed genome map for Euptelea pleiosperma, revealing its ancient lineage and unique genomic characteristics.
  • The study finds that Eupteleaceae shows the slowest molecular evolution among angiosperms, which is linked to its stable genome structure, ancient growth habits, and specific environmental needs, offering insights into plant adaptation amidst environmental changes.

Objective: Acute myeloid leukemia (AML) is a hematological malignancy. This study was attempted to uncover the effects of long noncoding RNA taurine-upregulated gene1 (TUG1) on the viability and apoptosis of AML cells.

Methods: QRT-PCR was implemented to examine the expression of TUG1, miR-221-3p and KIT in AML.

Article Synopsis
  • Petals can vary in complexity, with features like lobes and spurs influencing their design, and they play an important role in the evolution of angiosperms.
  • Researchers conducted studies on the Ranunculaceae family to uncover the genetic mechanisms involved in the development of elaborate petals, identifying specific genes linked to this complexity.
  • Their findings reveal key genes responsible for various petal characteristics, contributing to a greater understanding of how plants diversify their structures.

The genus (Ranunculaceae) has been cultivated as ornamental and medicinal plants for centuries. With petal spurs of strikingly diverse size and shape, has also been recognized as an excellent system for evolutionary studies. Pollinator-mediated selection for longer spurs is believed to have shaped the evolution of this genus, especially the North American taxa.

Identification and comparison of the conserved and variable downstream genes of floral organ identity regulators are critical to understanding the mechanisms underlying the commonalities and peculiarities of floral organs. Yet, because of the lack of studies in nonmodel species, a general picture of the regulatory evolution between floral organ identity genes and their targets is still lacking. Here, by conducting extensive chromatin immunoprecipitation followed by high-throughput sequencing (ChIP-seq), electrophoretic mobility shift assay and bioinformatic analyses, we identify and predict the target genes of a petal identity gene, AqAPETALA3-3 (AqAP3-3), in Aquilegia coerulea (Ranunculaceae) and compare them with those of its counterpart in Arabidopsis thaliana, AP3.

The family Ranunculaceae, a member of early-diverging eudicots that is increasingly being used as a model for the study of plant developmental evolution, has been the focus of systematic studies for centuries. Recent studies showed that the family can be divided into 14 tribes, with Glaucideae, Hydrastideae, and Coptideae being the successive basal-most lineages. The relationships among the remaining 11 tribes, however, remain controversial, so that a clear picture of character evolution within the family is still lacking.

Background: Pneumococcal meningitis is one of the most common infectious diseases with a high-mortality rate and long-term neurological sequelae, affecting up to 50% of survivors. Pneumococcal compounds are pro-inflammatory mediators that induce an innate immune response and tryptophan degradation through the kynurenine pathway. Vitamin B6 (vitB6) is an important vitamin which acts as a cofactor at the active sites of enzymes that catalyze a great number of reactions involved in the metabolism of tryptophan through the kynurenine pathway and may thus limit the accumulation of neurotoxic metabolites and preserve the cellular energy status.

Purpose: Metastasis is the leading cause of death for a majority of cancer patients, and thus the need to understand the biology of metastasis becomes increasingly acute. When metastasis is initiated in tumor progression remains obscure. Better understanding of mechanisms regulating acquisition of metastatic ability in tumor cells will provide novel therapeutic targets and prevention of metastasis in clinics accompanied with the treatment of the primary tumor might be helpful in reducing metastasis-related mortality.

AP1/FUL, SEP, AGL6, and FLC subfamily genes play important roles in flower development. The phylogenetic relationships among them, however, have been controversial, which impedes our understanding of the origin and functional divergence of these genes. One possible reason for the controversy may be the problems caused by changes in the exon-intron structure of genes, which, according to recent studies, may generate non-homologous sites and hamper the homology-based sequence alignment.

Integration of hepatitis B virus (HBV) DNA into the human liver cell genome is believed to promote HBV-related carcinogenesis. This study aimed to quantify the integration of HBV DNA into the leukocyte genome in hepatocellular carcinoma (HCC) patients in order to identify potential biomarkers for HBV-related diseases. Whole-genome comparative genomic hybridization (CGH) chip array analyses were performed to screen gene copy number variations (CNV) in the leukocyte genome, and the results were confirmed by quantitative polymerase chain reaction (qPCR).

Purpose: Portal vein tumor thrombus (PVTT) is a major complication of hepatocellular carcinoma (HCC) and is associated with poor survival. Long noncoding RNAs (lncRNA) contribute to HCC metastasis, but whether and how lncRNAs affect PVTT development remains unclear. In the present study, a novel highly expressed lncRNA (ICAM-1-related, ICR) was identified in ICAM-1(+)cancer stem cells (CSC) in HCC.
