Coffee break: Protein alterations after drinking

Date: Nov 15, 2017

Author: Steve Down

A proteomics study of coffee drinkers in Sweden has uncovered inverse associations with two proteins that have been linked to appetite suppression and a number of diseases, including respiratory disorders, Alzheimer's disease and cancer.

E-Cigarettes: As dangerous as cigarettes?

Date: Nov 1, 2017

Author: Steve Down

The safety of e-cigarettes has been thrown into doubt following new research which revealed that it induces high levels of proteins in the lungs that are linked with cystic fibrosis, COPD and bronchitis.

Influenza A proteins: Individual proteome variations

Date: Oct 15, 2017

Author: Steve Down

Scientists in the US have shown that the proteomes of normal human bronchial epithelial cells are unique for individual people and also respond to infection by the influenza A virus in different ways, findings which could be used to identify people more susceptible to the disease.

Journal Highlight: In-gel and OFFGEL-based proteomic approach for authentication of meat species from minced meat and meat products

Date: Sep 4, 2017

Author: separationsNOW

In-gel 2D gel electrophoresis and an OFFGEL-based proteomic method followed by the MALDI-TOF MS analysis of proteins have been used to authenticate raw and cooked water buffalo, sheep and goat meat and their mixes.

Dominant or submissive: Proteomic clues to behavioural disorders

Date: Aug 15, 2017

Author: Steve Down

The expression of many proteins in the hippocampi of mice are modified by dominant and submissive behaviour, say scientists in Israel in the first study of its kind which will help to decode the molecular mechanisms of psychiatric disorders and lead to therapeutic solutions.
