Observations on Centrifugation: Application to Centrifuge Development [PDF]

Clinical Chemistry, 1999
Abstract This report outlines the background to the development of an automated, serial, discrete centrifuge, reporting on the criteria considered essential in such an instrument. We established the criteria by examining the detailed logistics of centrifuge operation in a hospital laboratory.

Centrifugal Etching

Journal of The Electrochemical Society, 2003
A cell consisting of a rotatable double-walled cylinder is described for the study of etching under conditions of enhanced gravity. Rotation rates of 6000 revolutions per minute giving g values of up to 600 were possible with the set-up. The cell was tested by etching masked patterns in a copper plate with an aqueous FeCl3 solution.

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

FEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

The anti‐CRISPR protein AcrIE8.1 inhibits the type I‐E CRISPR‐Cas system by directly binding to the Cascade subunit Cas11

FEBS Letters, EarlyView.
In this study, we present the structure of AcrIE8.1, a previously uncharacterized anti‐CRISPR protein that inhibits the type I‐E CRISPR‐Cas system. Through a combination of structural and biochemical analyses, we demonstrate that AcrIE8.1 directly binds to the Cas11 subunit of the Cascade complex to inhibit the CRISPR‐Cas system.

Solid-liquid separation techniques for efficient recovery of P2O5 from phosphoric sludge [PDF]

Chemical Industry and Chemical Engineering Quarterly, 2020
Phosphoric acid sludge is one of the prominent problems in the phosphate industry. Its production co-occurs with large losses of P2O5 that affect the process performance. Management and valorization of this waste is a key issue.

An intracellular transporter mitigates the CO2‐induced decline in iron content in Arabidopsis shoots

FEBS Letters, EarlyView.
This study identifies a gene encoding a transmembrane protein, MIC, which contributes to the reduction of shoot Fe content observed in plants under elevated CO2. MIC is a putative Fe transporter localized to the Golgi and endosomal compartments. Its post‐translational regulation in roots may represent a potential target for improving plant nutrition ...

Evaluation of Platelet Count, Anti-microbial Efficacy, and Fibrin Network Pattern for Advanced Platelet Rich Fibrin versus Titanium Platelet Rich Fibrin Prepared from Blood Samples of Young Adults: An Ex-vivo Study [PDF]

Journal of Clinical and Diagnostic Research
Introduction: Platelet concentrates have gained popularity in periodontal regenerative therapy owing to their autologous nature. Platelet Rich Fibrin (PRF) can be classified into various types based on the centrifugation protocol.
