The Influence of Friction Forces in Metal Powders Compaction Process of Stainless Steel 316L

The Annals of “Dunarea de Jos” University of Galati. Fascicle IX, Metallurgy and Materials Science, 2011
The purpose of this study is to determine as precisely the influence of friction in the compaction of powders, and "conversion" of it, increasing densification.

Influence of the face surface shape of the piston on the limit value of compaction stress in the process of dry ice agglomeration

MATEC Web of Conferences, 2019
This paper presents the results of research on improving the efficiency of the mechanical agglomeration through describing the influence of the shape of the piston pressure face on the limit force value.

Targeting transcription factors associated with hemoglobinopathies: Lessons from successful interventions and implications for cancer

Molecular Oncology, EarlyView.
This review summarizes the transcription factors, repressive chromatin‐modifying complexes, and epigenetic mechanisms that control fetal hemoglobin repression. Notably, many regulators of γ‐globin silencing also function in transcriptional and epigenetic networks that drive cancer, highlighting opportunities to translate advances in hemoglobinopathy ...

Biochar Amendment as a Mitigation Against Freezing–Thawing Effects on Soil Hydraulic Properties

Agronomy
Seasonal freeze–thaw cycles compromise soil structure, thereby increasing hydraulic conductivity but diminishing water retention capacity—both of which are essential for sustaining crop health and nutrient retention in agricultural soils.

EFFECT OF ULTRASONIC-ASSISTED COMPACTION ON DENSITY AND HARDNESS OF Cu-CNT NANOCOMPOSITES SINTERED BY CAPSULE-FREE HOT ISOSTATIC PRESSING

Acta Metallurgica Slovaca, 2017
Cu-CNTs composites were prepared with and without ultrasonic-assisted compaction in this work. The samples were sintered by capsule-free hot isostatic pressing at 920oC and 50 MPa Ar gases.

Pharmacological chromatin remodeling enhances response to estrogen therapy in ER+ breast cancer

Molecular Oncology, EarlyView.
Estrogen therapy elicits clinical benefit in ~ 30% of patients with endocrine‐resistant estrogen receptor (ER)‐positive breast cancer. Based on findings that ER transcriptional activation underlies response to estrogen therapy, we tested the effects of epigenetic dysregulation via pharmacological inhibition of histone deacetylases (HDACi).

Estimativa da resistência mecânica à penetração de um latossolo vermelho sob cultura perene no norte do estado do Paraná Estimating penetration resistance of an oxisol under perennial crop in northern Paraná state

Revista Brasileira de Ciência do Solo, 2008
Uma das propriedades físicas importantes para o manejo e estudo da qualidade física dos solos é sua resistência à penetração, uma vez que esta propriedade se apresenta relacionada a diversos atributos do solo indicadores do grau de compactação.

Intrapatient tumour heterogeneity and clonal evolution in an autopsy study of metastatic salivary gland cancer

Molecular Oncology, EarlyView.
Tumour heterogeneity and clonal evolution of metastatic salivary gland cancer were evaluated in two patients with adenoid carcinoma and one patient with myoepithelial carcinoma. Radiology‐guided autopsy enabled multi‐region sampling (total samples n = 149), followed by whole‐genome sequencing and phylogenetic reconstruction (17 tumour samples, 4–7 per ...

Unraveling the epigenetic code in cancer cell–tumor microenvironment crosstalk

Molecular Oncology, EarlyView.
Epigenetic regulation is a key driver of cancer development and progression. Diverse epigenetic alterations in cancer cells and components of the tumor microenvironment (TME) orchestrate their communication through multiple mechanisms. We discuss how the epigenetic code coordinates bidirectional cancer cell–TME crosstalk to promote cancer progression ...

Arginine methylation as a regulatory ratchet in cancer: From substrate selection to malignant‐state stabilization

Molecular Oncology, EarlyView.
Arginine methylation can be viewed as a persistence‐prone post‐translational modification regulated by a network of PRMTs. Competitive and compensatory interactions among PRMTs can redistribute methylation across substrate pools shaped by sequence, structural, spatial, and environmental layers, reinforcing RNA‐processing, chromatin, and signaling ...
