As the core of leaf functional traits, the trade-off relationship between the petiole and lamina expresses the plant's adaptability to the environment in terms of support structure and photosynthesis. We investigated the proportions of allometric growth in the relationship between the petiole and the lamina of broadleaf woody plants in temperate highland Tianshan Mountains montane forests through three dimensions (length, area, and mass), including the length of the lamina (LL) and the length of the petiole (PL), and the area of the lamina (LA) and petiole cross sectional area (PCA) versus the mass of the lamina (LM) and the mass of the petiole (PM), as well as exploring the characteristics of the variance in response to seasonal changes. We found that the functional traits in all three dimensions showed a clear convergent evolution as the seasons progressed, that is, a "seasonal effect" of increasing and then decreasing.

Cellular senescence is characterized by a stable cell cycle arrest and a hypersecretory, proinflammatory phenotype in response to various stress stimuli. Traditionally, this state has been viewed as a tumor-suppressing mechanism that prevents the proliferation of damaged cells while activating the immune response for their clearance. However, senescence is increasingly recognized as a contributing factor to tumor progression.

Connection between oral health and chronic diseases.

MedComm (2020)

January 2025

State Key Laboratory of Oral Diseases, National Center for Stomatology, National Clinical Research Center for Oral Diseases, Department of Conservative Dentistry and Endodontics, West China Hospital of Stomatology Sichuan University Chengdu Sichuan China.

Chronic diseases have emerged as a paramount global health burden, accounting for 74% of global mortality and causing substantial economic losses. The oral cavity serves as a critical indicator of overall health and is inextricably linked to chronic disorders. Neglecting oral health can exacerbate localized pathologies and accelerate the progression of chronic conditions, whereas effective management has the potential to reduce their incidence and mortality.

Eupalinolide B inhibits periodontitis development by targeting ubiquitin conjugating enzyme UBE2D3.

MedComm (2020)

January 2025

Department of Urology, Guangdong Provincial Clinical Research Center for Geriatrics, Shenzhen Clinical Research Centre for Geriatrics Shenzhen People's Hospital, The First Affiliated Hospital, Southern University of Science and Technology Shenzhen China.

Periodontitis is a chronic periodontal inflammatory disease caused by periodontal pathogens commonly seen in adults. Eupalinolide B (EB) is a sesquiterpenoid natural product extracted from Eupatorium lindleyanum and has been reported as a potential drug for cancers and immune disorders. Here, we explored the ameliorative effects and underlying molecular mechanism of EB on periodontitis for the first time.

Hepatic ischemia-reperfusion injury (IRI) poses a significant threat to clinical outcomes and graft survival during hemorrhagic shock, hepatic resection, and liver transplantation. Current pharmacological interventions for hepatic IRI are inadequate. In this study, we identified ginsenoside Rk2 (Rk2), a rare dehydroprotopanaxadiol saponin, as a promising agent against hepatic IRI through high-throughput screening.

Biofilm infections are chronic infections which are difficult to diagnose. Biofilm infections are tolerant to antibiotics and the defense mechanisms of the host. Patients with the genetic disease cystic fibrosis (CF) produce viscid mucus in the respiratory tract and therefore suffer from chronic biofilm infections in their lungs and paranasal sinuses.

Lip Melanosis Postdermal Filler Injection: Second Case Report and Literature Review.

Case Rep Dent

January 2025

Division of Oral Medicine, Department of Oral Medicine and Diagnostic Sciences, College of Dentistry, King Saud University, Riyadh, Saudi Arabia.

Oral pigmentation can arise from various factors, including physiological and pathological, or as a manifestation of an underlying systemic disease. We present an atypical case of dermal filler-related complication, in which clinical lip pigmentation was observed. This condition can pose a diagnostic challenge in accurately identifying its cause.

Mucopolysaccharidosis (MPS) Type III (MPS III) or Sanfilippo syndrome is a rare autosomal recessive inherited metabolic disorder. This disorder is responsible for lysosomal storage disorder at the cellular aspect. Due to lysosomal enzyme perturbance leading to the alteration of macromolecule metabolisms, this cellular perturbance causes multiple severe systemic and mental outcomes.

Evaluation of predictions of disordered binding regions in the CAID2 experiment.

Comput Struct Biotechnol J

December 2024

Department of Computer Science, Virginia Commonwealth University, Richmond, VA 23284, USA.

A large portion of the Intrinsically Disordered Regions (IDRs) in protein sequences interact with proteins, nucleic acids, and other types of ligands. Correspondingly, dozens of sequence-based predictors of binding IDRs were developed. A recently completed second community-based Critical Assessments of protein Intrinsic Disorder prediction (CAID2) evaluated 32 predictors of binding IDRs.

Background: In recent decades, relapsing remitting multiple sclerosis (MS) became more treatable through new disease-modifying therapies (DMTs). Identifying safe treatments with minimal fetal risks for family planning is needed.

Methods: In this prospective cohort from the German MS and Pregnancy Registry (DMSKW), we analyzed pregnancy and neonatal outcomes in MS-patients using descriptive statistics and logistic/linear regression models to compare DMT-exposed pregnancies to DMT-unexposed pregnancies.

Objective: To compare direct, non-medical out-of-pocket expenditures (OOPE) between mothers receiving Alberta Family Integrated Care (FICare™) versus standard care (SC) during their infant's neonatal intensive care unit (NICU) admission and explore factors influencing spending extremes.

Methods: In this exploratory, concurrent mixed-methods sub-study, we compared mother-reported OOPE from Alberta FICare™ and SC parent journals. We thematically analyzed hand-written notes from 30 journals with the highest and lowest 5 % of OOPE.
