Novel intercellular spread mode of respiratory syncytial virus contributes to neutralization escape.

Developing widely used respiratory syncytial virus (RSV) vaccines remains a significant challenge, despite the recent authorization of two pre-F vaccines for elderly adults. Previous reports have suggested that even when vaccine-induced immunity generates high titers of potent neutralizing antibodies targeting the pre-F protein, it may not fully inhibit breakthrough of RSV infections. This incomplete inhibition of RSV breakthrough infections can lead to an increased risk of enhanced respiratory disease (ERD) in vaccinated individuals.

Impact of Lumbar Fusion Internal Fixation on Lumbar Disc Herniation in Young Patients: A Retrospective Study.

This study aimed to investigate the impact of lumbar fusion on lumbar function in young patients. MATERIAL AND METHODS A retrospective analysis was conducted on 330 patients diagnosed with LDH admitted to our hospital.

A Randomized Controlled Clinical Trial Investigating the Weaning Process From Mechanical Ventilation in Elderly Patients With Dementia.

Background: Limited data is available regarding the weaning techniques employed for mechanical ventilation (MV) in elderly patients with dementia in China.

Objective: The primary objective of this study is to investigate diverse weaning methods in relation to the prognostic outcomes of elderly patients with dementia undergoing MV in the intensive care unit (ICU). Specifically, we seek to compare the prognosis, likelihood of successful withdrawal from MV, and the length of stay (LOS) in the ICU.

Purpose: To assess the predictive value of an ultrasound-based radiomics-clinical nomogram for grading residual cancer burden (RCB) in breast cancer patients.

Methods: This retrospective study of breast cancer patients who underwent neoadjuvant therapy (NAC) and ultrasound scanning between November 2020 and July 2023. First, a radiomics model was established based on ultrasound images.

Molecular insights into the catabolism of dibutyl phthalate in Pseudomonas aeruginosa PS1 based on biochemical and multi-omics approaches.

A comprehensive understanding of the molecular mechanisms underlying microbial catabolism of dibutyl phthalate (DBP) is still lacking. Here, we newly isolated a bacterial strain identified as Pseudomonas aeruginosa PS1 with high efficiency of DBP degradation. The degradation ratios of DBP at 100-1000 mg/L by this strain reached 80-99 % within 72 h without a lag phase.

Pro-ferroptotic signaling promotes arterial aging via vascular smooth muscle cell senescence.

Senescence of vascular smooth muscle cells (VSMCs) contributes to aging-related cardiovascular diseases by promoting arterial remodelling and stiffness. Ferroptosis is a novel type of regulated cell death associated with lipid oxidation. Here, we show that pro-ferroptosis signaling drives VSMCs senescence to accelerate vascular NAD loss, remodelling and aging.

[Comparative study of purgative pharmacological effects and mechanisms of Moringa oleifera leaves and Rhei Radix et Rhizoma].

Ultrasound characteristics of breast fibromatosis mimicking carcinoma.

Purpose: To explore the value of ultrasound (US) characteristics in diagnosing breast fibromatosis (BF) and evaluate their differences from breast carcinoma.

Methods: A total of 121 patients with BF (n = 24, 29 lesions) or invasive ductal carcinoma (IDC) (n = 97, 102 lesions) of the breast were included. Their clinical and US findings were recorded and analyzed.

[Research progress in pathogenesis and traditional Chinese medicines treatment of ischemic stroke-related headache].

Headache is a common clinical complication of ischemic stroke. As a precursor of stroke, headache occurs repeatedly in the convalescent period of ischemic stroke, leading to secondary stroke and seriously hindering patients' rehabilitation. Currently, it is believed that the pathogenesis of ischemic stroke-related headache is associated with the abnormal release of vasoactive substances, high platelet aggregation, and stimulation of intracranial pain-sensitive structures.

[Traditional application and modern research progress on new foreign medicinal resources].

Chinese medicinal resources are the material basis for the survival and development of traditional Chinese medicine(TCM)and the sustainable development of Chinese medicinal resources is also an important project for the modernization of TCM in China. With the increasing demand for Chinese medicinal resources in China, over-exploitation has destroyed Chinese medicinal resources, resulting in a shortage of many natural medicinal resources in China and making the sustainable development of TCM in trouble. The introduced new foreign medicinal resources have become effective supplement and replacement for Chinese medicinal resources to some extent.

A nomogram incorporating clinical, conventional ultrasound and shear wave elastography findings for distinguishing pleomorphic adenoma from Warthin's tumor of the major salivary glands.

Objective: Pre-operative differentiation between pleomorphic adenoma (PA) and Warthin's tumor (WT) of the major salivary glands is crucial for treatment decisions. The purpose of this study was to develop and validate a nomogram incorporating clinical, conventional ultrasound (CUS) and shear wave elastography (SWE) features to differentiate PA from WT.

Methods: A total of 113 patients with histological diagnosis of PA or WT of the major salivary glands treated at Fujian Medical University Union Hospital were enrolled in training cohort ( = 75; PA = 41, WT = 34) and validation cohort ( = 38; PA = 22, WT = 16).

Contrast-Enhanced Ultrasound Imaging: Novel Method for the Evaluation of Chronic Alcohol-Induced Testicular Damage.

Objective: The goals of this study were to determine whether contrast-enhanced ultrasound (CEUS) imaging could be used for assessment of chronic alcohol-induced testicular damage (CAITD) and to explore the relationships between the laboratory and pathological findings of CAITD and the quantitative parameters of CEUS.

Methods: Thirty-six rabbits were randomly divided into a chronic ethanol exposure (CEE) group and negative control (NC) group, which were further randomly divided into six groups with equal numbers of rabbits by period of exposure (30 d, 60 d, 90 d). All rabbits underwent conventional US and CEUS imaging at the end of the induction period.

Metrnl deficiency retards skin wound healing in mice by inhibiting AKT/eNOS signaling and angiogenesis.

Meteorin-like (Metrnl) is a novel secreted protein with various biological activities. In this study, we investigated whether and how Metrnl regulated skin wound healing in mice. Global Metrnl gene knockout mice (Metrnl) and endothelial cell-specific Metrnl gene knockout mice (EC-Metrnl) were generated.

[The role of semaphorin 4D in the mechanism of bisphosphonate-related osteonecrosis of the jaw in rats].

Purpose: To study the expression level of semaphorin 4D (Sema4D) in bisphosphonate-related osteonecrosis of the jaw (BRONJ) and to explore its possible role in the occurrence of BRONJ.

Methods: BRONJ-like rat model was established by intraperitoneal injection of zoledronic acid assisted with tooth extraction. The maxillary specimens were extracted for imaging and histological examination, and bone marrow mononuclear cells(BMMs) and bone marrow mesenchymal stem cells(BMSCs) of each group were obtained in vitro for co-culture.

Predictive value of left atrial strain analysis in adverse clinical events in patients with hypertrophic cardiomyopathy: a CMR study.

Background: A subset of patients with hypertrophic cardiomyopathy (HCM) will experience adverse clinical events such as heart failure (HF), cardiovascular death, and new-onset atrial fibrillation (AF). Current risk stratification methods are imperfect and limit the identification of patients at high risk for HCM. This study aimed to evaluate the role of cardiac magnetic resonance (CMR)-derived left atrial strain parameters in the occurrence of adverse clinical events in patients with HCM.

Short-term effects of wildfire on soil arthropods in a semi-arid grassland on the Loess Plateau.

Fires lead to dramatic shifts in ecosystems and have a large impact on the biota. Soil organisms, especially soil fauna, are often used as indicators of environmental change. At present, minimal attention has been paid to using soil fauna as an indicator of environmental change after a fire.
