Ultra-high performance concrete under direct tension: Investigation of a hybrid of steel and synthetic fibers

, 2023
Ultra-high performance concrete (UHPC) offers superior tensile properties in comparison to normal and high-strength concrete. This is known to largely depend on the fibers included in the UHPC mixtures.

Hijacking emergency granulopoiesis: Neutrophil ontogeny and reprogramming in cancer

Molecular Oncology, EarlyView.
Neutrophils are highly plastic innate immune cells; their functions in cancer extend beyond the tumour microenvironment. This Review summarises current understanding of neutrophil maturation and heterogeneity and highlights tumour‐induced granulopoiesis as a systemic programme that expands immature, immunosuppressive neutrophils via tumour‐derived ...

Constitutive Model for Plain and Steel-Fibre-Reinforced Lightweight Aggregate Concrete Under Direct Tension and Pull-Out

Fibers
In the present study, a programme of experimental investigations was carried out to examine the direct uniaxial tensile (and pull-out) behaviour of plain and fibre-reinforced lightweight aggregate concrete.

Transcriptional profiling of circulating extracellular vesicles from prebiopsy prostate cancer patients

Molecular Oncology, EarlyView.
RNA profiling of circulating extracellular vesicles (EVs) from blood samples of men undergoing prostate biopsy identifies transcripts associated with clinically significant prostate cancer. Integrative analysis with public tumor datasets links EV‐derived gene signatures to tumor stage and progression‐free survival, highlighting CASP3, XRCC2, and RIT1 ...

Simulation of fracture in a quasi-brittle material in direct tension - a lattice model

, 1998
In this paper, results of simulation of stress-deformation response of a quasi-brittle material, like concrete, in direct tension using lattice model earlier proposed by Bhattacharya [2] (Bhattacharya GS.

Development of an individual warp beam tension control system for warp assembling machines in direct warp preparation

Journal of Engineered Fibers and Fabrics
Warp preparation is a process prior to weaving that brings all the ends side by side and then winding them on a warp beam with the same tension and length at a predetermined width, density and length.

Adaptor protein CIN85 potentiates the motility of osteosarcoma cells via the Akt/mTOR and MMP2‐COL3A1 axis

Molecular Oncology, EarlyView.
CIN85 is highly expressed in osteosarcoma, particularly in metastatic lesions. Its overexpression increases cell migration and Matrigel invasion, while silencing CIN85 suppresses these behaviors. Transcriptome analysis shows that CIN85 regulates MMP2, COL3A1, and Akt/mTOR signaling. Targeting these pathways reverses CIN85‐induced motility, highlighting

Direct and Flexural Tension Test Methods for Determination of the Tensile Stress-Strain Response of UHPFRC

, 2012
Hipermat, KASSEL, ALLEMAGNE, 07-/03/2012 - 09/03/2012The tensile stress-strain response of Ultra-High Performance Fiber Reinforced Concrete (UHPFRC) is a fundamental mechanical behavior, and knowledge of this response is necessary for appropriate use of ...

Metastasis on pause: How dormant tumor cells stay hidden within the tumor microenvironment and evade immune surveillance

Molecular Oncology, EarlyView.
Dormant cancer cells can hide in distant organs for years, evading treatment and the immune system. This review highlights how signals from the surrounding tissue and immune environment keep these cells inactive or trigger their reawakening. Understanding these mechanisms may help develop therapies to eliminate or control dormant cells and prevent ...
