Effect of sulfur aggregates on mechanical resistance and durability for SFRHPC with the addition of slag

open access: yesMATEC Web of Conferences, 2014
The transformation of sulfides present in the aggregate to sulfates causes internal sulfate attack (ISA) by formation of secondary ettringite in the hardened concrete.

Sulfate attack and the role of internal carbonate on the formation of thaumasite

open access: yes, 2007
The sulfate attack is known to influence the durability of concrete. In general, significant damage due to sulfate interaction results in the structural breakdown of the concrete structure. However, the precipitation of thaumasite due to sulfate concentration, leaching and the role of internal carbonate in case of limestone filler in cement is still ...

IL‐7R‐Enriched Extracellular Vesicles From the Thymus Drive Colitis via Promoting Neutrophil Extracellular Trap Formation

open access: yesAdvanced Science, EarlyView.
Inflammatory bowel disease (IBD) pathogenesis remains unclear. This study reveals that thymus‐originated IL‐7R‐enriched extracellular vesicles exacerbate colitis by promoting neutrophil extracellular traps via a thymus‐gut axis, uncovering an inter‐organ communication mechanism in inflammatory bowel disease pathogenesis.

UCHL3 Regulates Subgenomic Flaviviral RNA Condensates to Promote Virus Propagation

open access: yesAdvanced Science, EarlyView.
ABSTRACT Flavivirus subgenomic RNAs (sfRNAs) antagonise antiviral defences, yet how sfRNAs are organized and maintained in cells remains poorly understood. Here we identify ubiquitin C‐terminal hydrolase L3 (UCHL3) as a post‐translational regulator of flavivirus sfRNA stability and function.

The manage strategy in a morbid obesity patient with bronchospasm during general anesthesia

open access: yesJournal of Medical Sciences, 2019
During general anesthesia, anesthesiologists encounter problems including difficult airway intubation, high respiratory airway pressure, fluctuation of blood pressure, and poor oxygen saturation, especially in obese patients.

Astrocytic Phenotypic Switching in Posterior Piriform Cortex Orchestrates Bone Cancer Pain–Depression Comorbidity via Purinergic–Noradrenergic Signaling

open access: yesAdvanced Science, EarlyView.
Bone cancer pain and depression share a common origin: astrocytic A2‐to‐A1 transition in the posterior piriform cortex. This phenotypic shift disrupts the ATP–adenosine–A2AR–norepinephrine axis, simultaneously driving nociceptive and affective dysfunction.

Sustainable Fabrication of Tailored Bone Substitutes: From High‐Throughput Scaffold Manufacturing, Scaled‐Up HMSC Expansion to Dynamic Cultivation in a Perfusion Bioreactor

open access: yesAdvanced Science, EarlyView.
ABSTRACT The demand for off‐the‐shelf biocompatible bone substitutes has driven the development of numerous independent in vitro technologies to generate products resembling physiological tissues. Due to technical challenges and overly simplified cultivation approaches/niches, the end‐products are often uniformly shaped and inferior to native bone ...

Some Durability Test of No-Fine Concrete

open access: yesJournal of Engineering, 2017
In this study, two types of mixes were adopted by using two grading of coarse aggregate. The practical side of this study was to produce no-fine aggregate concrete by using crushed clay brick aggregates.

Study on the spatiotemporal evolution and prediction of internal porosity in concrete specimens under sulfate attack based on machine learning models

open access: yesResults in Engineering
Concrete structures deteriorate due to sulfate attack, leading to changes in porosity. Understanding porosity evolution under sulfate attack helps improve concrete durability through protective coatings like silane.
