Unravelling the Web of Life: Incomplete Lineage Sorting and Hybridisation as Primary Mechanisms Over Polyploidisation in the Evolutionary Dynamics of Pear Species.

The traditional Tree of Life (ToL) model is increasingly challenged by the Web of Life (WoL) paradigm, which offers a more accurate depiction of organismal phylogeny, particularly in light of the incongruences often observed between gene and species trees. However, the absence of a standardised method for resolving evolutionary mechanisms - such as Incomplete Lineage Sorting (ILS), hybridisation, introgression, polyploidisation, and whole-genome duplication - remains a significant obstacle in defining the WoL. Characterised by extensive hybridisation events, the pear genus Pyrus provides an ideal model for exploring these complexities.

Association between the PSCA rs2976392 polymorphism and susceptibility to gastric cancer: a meta-analysis.

Background: Genetic polymorphisms, such as PSCA rs2976392, have been implicated in gastric carcinogenesis, but it is unclear whether there is a direct association. Thus, we conducted a comprehensive meta-analysis to evaluate the association between the PSCA rs2976392 polymorphism and susceptibility to gastric cancer (GC).

Methods: A systematic search of the PubMed, Web of Science, Embase, and Cochrane Library databases was performed up to 13 March 2025.

Phylogenomic insights into and its allies (Campanulaceae): Revisiting generic delimitation and hybridization dynamics.

Hybridization and introgression have long obscured relationships within and its relatives, complicating generic delimitation. Leveraging deep genome skimming (DGS) data, we generated a large dataset, including thousands of single-copy nuclear (SCN) genes and plastomes, to untangle this reticulate history. Specifically, 9.

Unraveling evolutionary pathways: allopolyploidization and introgression in polyploid Prunus (Rosaceae).

Allopolyploidization, resulting from hybridization and subsequent whole-genome duplication (WGD), is a fundamental mechanism driving evolutionary diversification across various lineages within the Tree of Life. The polyploid Prunus (Rosaceae), significant for its economic and agricultural value, provides an ideal model for investigating the evolutionary dynamics associated with allopolyploidy. In this study, we utilized deep genome skimming (DGS) data to demonstrate a comprehensive analytical framework for elucidating the underlying allopolyploidy that includes a newly adapted tool (DGS-Tree2GD) tailored explicitly for accurately detecting WGD events.

Plastome-based subgenus-level phylogenetic backbone of hawthorns: insights into the maternal position and taxonomic synopsis of (Rosaceae, Maleae).

The recent recognition of the five-subgenera classification within has prompted discussion about the maternal phylogenetic relationships among these subgenera, with inconsistencies in taxon sampling, marker selection, and inference methods contributing to differing interpretations. In this study, we performed deep genome skimming sequencing and assembled 63 whole plastomes, including 58 from and five from related genera as the outgroups. We employed multiple phylogenetic inference methods (Maximum Likelihood and Bayesian Inference) to reconstruct an accurate phylogeny.

Impact of delirium on post-discharge mortality in coronary care unit patients: A retrospective cohort study.

Background: Coronary care unit (CCU) patients surviving to discharge still face significant mortality. Delirium is common in CCU patients and has been associated with poorer CCU and in-hospital outcomes.

Aim: To assess the association between delirium and mortality after hospital discharge in CCU survivors.

A computational analysis of the oncogenic and anti-tumor immunity role of P4HA3 in human cancers.

Prolyl-4-hydroxylase subunit alpha3 (P4HA3) is a triple helical procollagen synthesis protein. The role of P4HA3 in cancer development is not well known and lacks comprehensive analyses among human cancers. This study aimed to investigate the relationship between P4HA3 expression and anti-tumor immunity and its prognostic value in pan-cancer.

Association between admission pan-immune-inflammation value and short-term mortality in septic patients: a retrospective cohort study.

Pan-Immune-Inflammation Value (PIV) has recently received more attention as a novel indicator of inflammation. We aimed to evaluate the association between PIV and prognosis in septic patients. Data were extracted from the Medical Information Mart for Intensive Care IV database.

Clinical Effect of Uterosacral and Cardinal Ligament Fixation versus Sacrospinous Ligament Fixation of Vaginal Vault Prolapse: A Retrospective Analysis.

Objective: This study aimed at comparing sacrospinous ligament fixation (SSLF) with uterosacral and cardinal ligament fixation (USCLF) concerning complications and outcomes in patients with pelvic organ prolapse (POP).

Methods: A retrospective analysis was performed on the clinical data of patients with POP stage III or above uterine prolapse treated at Wenzhou People's Hospital from January 2013 to December 2019. Patients were divided into two groups: USCLF group and SSLF group.

Photosynthetic compensation of non-leaf organ stems of the invasive species Sphagneticola trilobata (L.) Pruski at low temperature.

Biological invasion is a hot topic in ecological research. Most studies on the physiological mechanisms of plants focus on leaves, but few studies focus on stems. To study the tolerance of invasive plant (Sphagneticola trilobata L.

Lysyl oxidase and hypoxia-inducible factor 1α: biomarkers of gastric cancer.

Background: Gastric cancer (GC) is one of the main causes of cancer mortality worldwide. Recent studies on tumor microenvironments have shown that tumor metabolism exerts a vital role in cancer progression.

Aim: To investigate whether lysyl oxidase (LOX) and hypoxia-inducible factor 1α (HIF1α) are prognostic and predictive biomarkers in GC.

Clinical efficacy of pelvic autologous tissue reconstruction in treating pelvic organ prolapse in 36 patients.

miR-218 suppresses the growth of hepatocellular carcinoma by inhibiting the expression of proto-oncogene Bmi-1.

Purpose: To identify microRNAs (miRNAs) directly regulating the proto-oncogene Bmi-1 expression in the development of hepatocellular carcinoma (HCC) and to explore the underlying molecular mechanisms.

Methods: Four HCC cell lines, including HepG2, Bel7404, Huh7, and PLC5, the normal hepatocellular cell line MIHA, and 30 HCC biopsies were included in this study. Potential miRNAs, which interact with Bmi-1 and are involved in the development of HCC were identified through bioinformatic analyses.

Effects of Gui Zhu Yi Kun formula on the P53/AMPK pathway of autophagy in granulosa cells of rats with polycystic ovary syndrome.

The aim of the present study was to investigate the molecular mechanism associated with the traditional Chinese medicine formula Gui Zhu Yi Kun formula (GZYKF), in the treatment of polycystic ovary syndrome (PCOS).

The effect of TP on cell growth was assayed using the MTT method.

Knockdown of IRF3 inhibits extracellular matrix expression in keloid fibroblasts.

Keloid is a pathologic fibro-proliferative disorder and is characterized by hyper-proliferation of fibroblasts and excess extracellular matrix (ECM) deposition. Interferon regulatory factor 3 (IRF3) is a member of the interferon-regulatory factor (IRF) family and has been shown to play a critical modulator in the progression of fibrosis. However, the function of IRF3 in dermal fibrosis remains unclear.
