Radiation Exposure in Percutaneous Zadek Osteotomy vs Open Haglund Resection: A Retrospective Comparative Study

open access: yesFoot & Ankle Orthopaedics
Background: Fluoroscopy is a vital imaging technique in orthopaedic surgery, particularly with the growing adoption of minimally invasive surgery (MIS). Because of their increased reliance on intraoperative imaging, MIS techniques may necessitate greater

Bile duct ligation in the rat causes upregulation of ZO-2 and decreased colocalization of claudins with ZO-1 and occludin [PDF]

open access: yes, 2018
As the only barrier between blood and bile compartments hepatocellular tight junctions play a crucial role in cholestasis-induced increase of biliary permeability. The molecular basis of this reversible defect is not known.

From Inflammatory Bowel Disease to Cancer: Gut Microbiota–Immune Microenvironment Crosstalk and Natural Product‐Based Therapeutic Opportunities

open access: yesCancer Nexus, EarlyView.
ABSTRACT Inflammatory bowel disease (IBD), primarily Crohn's disease and ulcerative colitis, is a chronic relapsing inflammatory disorder of the gastrointestinal tract and an important risk factor for IBD‐associated cancer. Increasing evidence suggests that gut microbiota dysbiosis, epithelial barrier dysfunction, and immune microenvironment remodeling

Impact of QSW‐ZVS on Input EMI Filter Design in DC‐DC Converters

open access: yesInternational Journal of Circuit Theory and Applications, EarlyView.
This paper analyzes the impact of quasi‐square wave zero voltage switching (QSW‐ZVS) on passive EMI filter design for DC‐DC buck converters. The extra element theorem (EET) is used to derive the design quantities that ensure converter performance is not altered, and the resulting damping element values are compared with those of traditional converters.

Resveratrol Ameliorates Allergic Rhinitis by Activating SIRT1 to Disrupt the Mitochondrial ROS‐Inflammation Vicious Cycle

open access: yesFlavour and Fragrance Journal, EarlyView.
This study demonstrates that resveratrol alleviates allergic rhinitis by activating SIRT1, thereby disrupting the mitochondrial ROS‐inflammatory cycle, improving mitochondrial function, promoting anti‐inflammatory M2 macrophage polarisation, and reducing epithelial oxidative damage.

Beyond Gut Modulation: A Critical Review of the Therapeutic Potential, Safety, and Clinical Prospects of Natural Polysaccharides for IBD

open access: yesFood Safety and Health, EarlyView.
In this review, we critically summarized the application of natural polysaccharides (NPs) for the treatment of IBD. This approach combines, in a unique way (right), the basic structure–activity relationships of NPs from different origins (left) with their multipronged mode of action, which involves modulation of the gut microbiota and other ...

Competitive elimination of ZO-1/ZO-2-deficient cells regulates epithelial barrier homeostasis

open access: yes
Summary Epithelia cover the body and form a barrier to segregate the internal body from the external environment. Epithelial tissues contact the external environment and are exposed to various stresses that are potentially deleterious for the epithelial barrier 1 .

Regulatory Effects of Ammonium Chloride in an In Vitro Model of Hepatic Encephalopathy: Mechanisms Involving ACTA2‐Mediated Cytoskeletal Remodeling

open access: yesiLABMED, EarlyView.
Hyperammonemic stress suppresses ACTA2 expression and induces F‐actin cytoskeletal remodeling in astrocytes. The resulting inhibition of FAK/c‐Src signaling contributes to apoptosis, G2/M arrest, AQP4‐mediated swelling and junction‐associated proteins dysregulation, revealing a central role for ACTA2‐dependent cytoskeletal dysfunction in hepatic ...

Microbial keystone taxa and metabolic signatures in centenarians regulate intestinal homeostasis during aging

open access: yesiMeta, EarlyView.
Clostridium scindens and its metabolite indole‐3‐acetic acid (IAA) are identified as a keystone taxon and metabolic signature in centenarians. Clostridium scindens enhances microbial network stability and produces IAA via its own amidase (AMIE) and aldehyde dehydrogenase (ALDH), thus promoting intestinal homeostasis by activating the aryl hydrocarbon ...

Epigenetic Regulation in the Pathogenesis of Renal Inflammation: Insights and Therapeutic Potentials

open access: yesiNew Medicine, EarlyView.
ABSTRACT Renal inflammation is a common pathological process in various kidney diseases, often initiated by factors such as toxins, ischemia, or autoimmune reactions. This inflammatory response can result in structural damage and a rapid decline in renal function.
