Anti-nuclear antibodies positive serum from systemic lupus erythematosus patients promotes cardiovascular manifestations and the presence of human antibody in the brain

Journal of Pharmacy and Bioallied Sciences, 2014
Background: Systemic lupus erythematosus (SLE) is characterized by the presence of anti-nuclear antibodies (ANAs) in the serum of patients. These antibodies may cross over into the brain resulting in the development of neuropsychiatric symptoms and ...

Cryo‐EM Analysis of a Tri‐Heme Cytochrome‐Associated RC‐LH1 Complex from the Marine Photoheterotrophic Bacterium Dinoroseobacter Shibae

Advanced Science, EarlyView.
Cryo‐EM reveals a closed 17‐subunit LH ring encircling the RC‐LH1 complex in Dinoroseobacter shibae, featuring a novel helix‐turn‐helix subunit bridging RC and LH. Mg2⁺/Ca2⁺ stabilizes the complex, while periplasmic Cyt c₂ mediates electron transfer via a tri‐heme Cyt to the special pair of bacteriochlorophylls. Insights into energy/electron efficiency

Experimental study on wave attenuation by vegetation by means of particle imaging velocimetry [PDF]

arXiv, 2020
Coastal vegetation serves as an ecological defense and plays an important role when facing marine disaster such as storm surge. In this study, we investigated experimentally the wave attenuation, including wave height and wave force decay, and flow field within rigid vegetation by means of particle imaging velocimetry (PIV).

Decoding Blastocystis‐Driven Mechanisms in Gut Microbiota and Host Metabolism

Advanced Science, EarlyView.
Blastocystis, a prevalent gut microbe, interacts with the host through metabolic and immune pathways, influencing cardiometabolic health. This perspective explores its role in modulating short‐chain fatty acid production, tryptophan metabolism, and immune signaling, potentially impacting cholesterol absorption, glucose metabolism, and vascular health ...

State of vegetative nervous system (vns) in children with biliary pathology

Neurology Bulletin, 1999
Results of complex study of VNS in 148 children with bile secretion system pathology have been presented. Disorders of functional state of vegetative regulation have been revealed, characterized by vagotonia, prevailing in initial vegetative tonus, hypersympaticotonic reactivity and insufficiency of vegetative system.

The Lung Microbiome Modulates Pain‐Like Behavior Via the Lung–Brain Axis in a Nitroglycerin‐Induced Chronic Migraine Mouse Model

Advanced Science, EarlyView.
Intratracheal neomycin alters pulmonary microbiota, activating the vagus nerve via lung brain‐derived neurotrophic factor/tropomyosin receptor kinase B (BDNF/TrkB) pathway, further projecting to nucleus of solitary tract (NTS), then dorsal raphe nucleus (DRN), where activated serotoninergic neurons increase brain serotonin, alleviating migraine.

Contrasting dynamics of seed banks and standing vegetation of annuals and perennials along a rainfall gradient [PDF]

arXiv, 2023
The soil seed bank is a major component of plant communities. However, long-term analyses of the dynamics of the seed bank and the ensuing vegetation are rare. Here, we studied the dynamics in plant communities with high dominance of annuals in Mediterranean, semiarid, and arid ecosystems for nine consecutive years.

Kinsenoside‐Loaded Microneedle Accelerates Diabetic Wound Healing by Reprogramming Macrophage Metabolism via Inhibiting IRE1α/XBP1 Signaling Axis

Advanced Science, EarlyView.
Gut metabolite trimethylamine N‐oxide accumulates in the diabetic wound area to amplify macrophage inflammation via enhancing glycolysis activities. Kinsenoside induces macrophage repolarization from M1 to M2 phenotype through inhibiting IRE1α/XBP1 pathway, followed by HIF‐1α‐glycolysis axis repression and mitophagy‐oxidative phosphorylation axis ...

Gut microbiota‐stem cell niche crosstalk: A new territory for maintaining intestinal homeostasis

iMeta, Volume 1, Issue 4, December 2022., 2022
Intestinal stem cells (ISCs) are protected by their niche and are regulated by Wnt, bone morphogenetic protein, and Notch. ISCs and their relationship with intestinal microbiota provide a feasible pathway to alleviate intestinal diseases. Diverse bacteria‐related postbiotics regulate ISCs and maintain their homeostasis.
