Emerging locally delivered antimicrobial and immunomodulatory approaches for the prevention/treatment of peri‐implant diseases

open access: yesPeriodontology 2000, EarlyView.
Abstract Peri‐implant diseases are dysbiosis‐mediated inflammatory disorders that occur in susceptible hosts. Antimicrobials and immunomodulatory agents therefore might be pertinent as adjunctive measures in the treatment of such disorders. The aim of this narrative review was to examine the existing evidence and assess the effectiveness of emerging ...

Sex differences in the prefrontal cortex and muscle oxygenation during exercise until exhaustion in endurance‐trained individuals

open access: yesExperimental Physiology, EarlyView.
Abstract figure legend During cardiopulmonary exercise testing, the decline in oxygenation in the prefrontal cortex of women is striking. This crucial brain area is directly involved in planning motor tasks. The decline is particularly pronounced at higher exercise intensities, especially after reaching the respiratory compensation point or anaerobic ...

Active mode-locking via pump modulation in a Tm-doped fiber laser

open access: yesAPL Photonics, 2016
We propose and experimentally realize a new class of actively mode-locking technique using pump modulation for rare-earth doped fiber lasers. A Tm-doped fiber laser at 2 μm is mode-locked using the proposed active mode-locking via pump modulation ...

MCT1‐mediated bidirectional propionate transport across human placental syncytiotrophoblast layer: insights from a trophoblast stem cell‐derived barrier model

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Propionate in the fetal circulation is thought to originate from fermentation of dietary fibre by the maternal gut microbiota. However, the mechanism of transplacental transport has remained unclear. Here, we measured propionate permeability using a placental barrier model generated by differentiating human placental trophoblast ...

Trace Ammonia Detection Based on Near-Infrared Fiber-Optic Cantilever-Enhanced Photoacoustic Spectroscopy

open access: yesPhotonic Sensors, 2019
A trace ammonia (NH3) detection system based on the near-infrared fiber-optic cantilever-enhanced photoacoustic spectroscopy (CEPAS) is proposed. A fiber-optic extrinsic Fabry-Perot interferometer (EFPI) based cantilever microphone has been designed to ...

Edulitin 2, a Ribotoxin‐Like Protein From Boletus edulis That Triggers Apoptosis in Colon Cancer Cells While Preserving the Integrity of the Intestinal Microbiota

open access: yeseFood, Volume 7, Issue 3, June 2026.
Edulitin 2 is a ribotoxin‐like protein exhibiting a potent antiproliferative activity towards Caco‐2 and HT29 cells by programmed cell death. However, edulitin 2 does not affect gut microbiota growth, despite damaging fungal ribosomes. ABSTRACT Porcini (Boletus edulis Bull.) are a reservoir of pharmacological biomolecules with health‐promoting ...

Single‐Cell Atlas of Subchondral Bone Marrow Lesions Reveals Proteostasis Dysfunction as a Druggable Mechanism for Early Osteoarthritis

open access: yesAdvanced Science, Volume 13, Issue 26, 8 May 2026.
This study reveals that abnormal mechanical stress downregulates the expression of HSP70 and impairs proteasome function in osteoarthritic bone cells, leading to misfolded collagen I accumulation and ER stress. When intracellular proteostasis capacity is exceeded, USP19 mediates the secretion of misfolded proteins into the extracellular space ...

A New Erbium Doped Fiber Amplifier

open access: yesJournal of Applied Sciences, 2009
In this study, a new configuration of an Erbium Doped Fiber Amplifier (EDFA’s) is proposed. Double-pass amplification in a dual-stage using a fiber loop-back is incorporated with a Tunable band pass filter. Spontaneous emission is filtered-out in the mid-section to ensure efficient amplification of the signal as it propagates along the fiber. High gain

Liver Fibrosis: Molecular Pathogenesis and Therapeutic Interventions

open access: yesMedComm, Volume 7, Issue 5, May 2026.
We systematically summarized the etiologies, diagnostic approaches, and pathogenic mechanisms of liver fibrosis. Also, the therapeutic interventions for liver fibrosis were systematically classified into two main categories: etiological treatment and mechanism‐based antifibrotic therapies.

Stable Single-Longitudinal-Mode Fiber Laser With Ultra-Narrow Linewidth Based on Convex-Shaped Fiber Ring and Sagnac Loop

open access: yesIEEE Access, 2019
In this investigation, a convex-shaped fiber ring (CSFR)-based single-longitudinal-mode (SLM) erbium-doped fiber laser (EDFL) is proposed and experimentally verified. The CSFR, composed of only two optical couplers and forming a double-ring architecture,
