Design and analysis strategies for robust microbiome ageing research

open access: yesFEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Investigation of 131I kinetics in the rats organism after a single intake [PDF]

open access: yesЯдерна фізика та енергетика, 2012
Kinetics of 131I in the organism of the laboratory rats is investigated after a single intake of various activities of isotopes. The isotope content is measured in different organs and tissues. Half-life of 131I has been determined.

Reconstructing enzyme evolution by protein engineering

open access: yesFEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Urinary Recovery of Salicylamide as Its Glucuronide in Liver Disease [PDF]

open access: yes, 1962
An attempt was made to establish the method for the estimation of glucuronide formation in vivo using salicylamide and further to study the alteration in the glucuronide formation in liver disease. The results were as follows: 1.

Decoding the dynamic extracellular matrix in cancer—3D models and bioscaffolds rewire the rules of tumor progression

open access: yesFEBS Letters, EarlyView.
Cancer progression is regulated by the dynamic matrix code of the tumor microenvironment, which influences cellular behavior and disease development. Importantly, matrix remodeling in three‐dimensional cancer models more accurately reflects in vivo conditions compared to conventional two‐dimensional systems.

1H NMR studies of urine during fasting: excretion of ketone bodies and acetylcarnitine

open access: yes, 1986
High-resolution 1H NMR spectroscopy has been applied to a study of urine from five normal human subjects during a 48-h period of fasting and for 22 h thereafter.

Excretion of the drug glutaron - a new derivative of glutamic acid

open access: yesФармакокинетика и Фармакодинамика, 2014
In the study of excretion of the drug was found that glutaron determined in urine for at least 72 hours of the study. Renal clearance is 123 ml/hour, extrarenal - 34.84 ml/hour by intravenous route of administration. Superiority over extrarenal and renal

Identification of a Shiga toxin A‐derived peptide internalized into Gb3 receptor‐bearing cells via interaction with the Shiga toxin B subunit

open access: yesFEBS Letters, EarlyView.
The process of internalization of the Shiga toxin A subunit via formation of a complex with the Shiga toxin B subunit, which specifically binds to the Gb3 receptor. The peptide is designed to act as a carrier of drugs into cancer cells. Here, we explored the potential of peptides derived from the catalytic A subunit of Shiga toxin (STxA) to be drug ...

Discerning protein pools by selective staining with self‐labeling tags

open access: yesFEBS Letters, EarlyView.
Cell surface proteins have an intra‐ and extracellular pool. Combining genetic fusion to self‐labeling tags that can be addressed with small molecule fluorophores allows separating these pools. We highlight recent developments and techniques for state‐of‐the‐art interrogation of cell surface proteins in the complex tissue setting.

Amélioration des bilans d'excrétion d'azote dans deux exploitations laitières de la région wallonne par un suivi raisonné des rations

open access: yesBiotechnologie, Agronomie, Société et Environnement, 2013
Improvements after precision dietary management of nitrogen rejection in two commercial dairy farms in Wallonia. Two dairy farms located in Pays de Herve and in Ardennes were followed at regular intervals in order to assess levels of nitrogen rejection ...
