Understanding plant adaptations in extreme environments is crucial, as these adaptations often confer advantages for survival. However, a significant gap exists regarding the genetic mechanisms underlying these adaptations and their responses to human-induced rapid environmental change (HIREC). This study addresses the question of whether genetic convergence occurs among plants with similar adaptive features, specifically focusing on isobilateral leaves in mangrove species.

High levels of the N7 methylguanosine (m7G) methyltransferase WD repeat domain 4 (WDR4) are associated with the progression of multiple tumors, including head and neck squamous cell carcinoma. Laryngeal cancer (LC) is the second most common malignant tumor of the head and neck. However, the role of WDR4 in LC remains unclear.

This study involved 88 participants completing 1860 sets of experiments under three conditions: sitting still, turning the head, and moving, providing subjective evaluations of wearing HMDs. A static torque testing device was used to simulate neck torque under flexion states.

However, there is still a lack of effective prevention and treatment strategies in clinical practice. As a metabolic disease, DN is accompanied by renal ectopic lipid deposition, and the deposited lipids further aggravate kidney injury.

Aims: Using network control theory, we evaluate if defective brain state transitions underlie working memory deficits in schizophrenia.
This study investigates the Cope elimination reaction, focusing on the mechanistic shift between concerted and stepwise pathways influenced by substituent effects. Experimental approaches, including kinetic isotope effects (KIEs) and linear free energy relationships (LFERs), alongside density functional theory (DFT) computations, were employed to explore the influence of substituents on the reaction kinetics and pathways. Our findings reveal temperature- and substituent-dependent partitioning between the concerted syn-β elimination and the stepwise E1cB mechanism, providing deeper insights into the mechanistic diversity of elimination reactions.

Although TR transcription is crucial in their life cycle, its regulation remains poorly understood. This study identifies the Mediator complex, E2F1-Dp, and Scalloped/dTEAD as key regulators of TR transcription.

Objective: To explore the diagnosis and treatment of acquired hemophilia A (AHA) based on the analysis of clinical data.
Methods: A retrospective analysis was conducted on the clinical manifestations, laboratory characteristics, treatment, and outcomes of 25 patients diagnosed with AHA who were admitted to the Second Hospital of Hebei Medical University.
Results: Among all patients, 11 cases had secondary factors, including 5 cases of autoimmune diseases, 3 cases of pregnancy-related disease, 1 case of pemphigoid, 1 case of Graves' disease, and 1 case of monoclonal gammaglobulinemia of unknown significance (MGUS).
Various prognostic models have been proposed to improve the accuracy of prognostic assessment for Myelodysplastic syndromes (MDS). Recently, the Molecular International Prognostic Scoring System (IPSS-M) has been developed. Here, we validated the accuracy of IPSS-M in Chinese MDS patients, and proposed a prognostic model more suitable for Chinese patients.

Previous studies have established an association between HAdV species B (HAdV-B) infection and severe community-acquired pneumonia (SCAP). However, the connection between SCAP-associated HAdV-B infection and host factor expression profile in patients has not been systematically investigated.

Traditionally, achieving high-concentration dispersions of two-dimensional (2D) nanosheets has proven challenging as they tend to agglomerate or re-stack under increased surface contact and Van der Waals attraction. Here, we unveil an excluded volume effect enabled by 2D morphology, which can be coupled with electrostatic repulsion to synthesize high-concentration aqueous graphene dispersions.

This novel index, which combines lipid metabolism and body composition, is the focus of this study, aimed at exploring its association with all-cause and specific mortality in an all-age adult population.
Methods: A longitudinal cohort study including 5,728 participants aged over 18 from nine cycles between 2001 and 2018 was enrolled and assessed.
Understanding protein structure is essential for elucidating its function. Cross-linking mass spectrometry (XL-MS) has been widely recognized as a powerful tool for analyzing protein complex structures. However, the effect of cross-linker backbone structure on protein dynamic conformation analysis remains less understood.

Purpose: To sort out the ideas and ways for nursing managers to identify problems in on-site supervision of nursing quality and to provide ideas and directions for being able to identify problems, identifying problems quickly, and identifying high-quality problems in the supervision.
Methods: A descriptive qualitative study was used to conduct face-to-face semi-structured interviews with 14 nursing managers from Bethune Hospital in Shanxi, China.
Low-iridium acid-stabilized electrocatalysts for efficient oxygen evolution reaction (OER) are crucial for the market deployment of proton exchange membrane (PEM) water electrolysis. Manipulating the in situ reconstruction of Ir-based catalysts with favorable kinetics is highly desirable but remains elusive. Herein, we propose an atomic ordering strategy to modulate the dynamic surface restructuring of catalysts to break the activity/stability trade-off.

Background: Cognitive impairment is a common and feared characteristic of aging processes, and one key mechanism of cognition is hippocampal synaptic structure. Previous studies have reported that gut microbiota dysbiosis occurred in neurodegenerative diseases and other brain disorders with cognitive impairment. However, it is not clear how gender differences affect cognitive impairment in aging processes and whether they affect synaptic structure and gut microbiota.
