Gut Microbiota in Primary Sarcopenia: Mechanisms and Potential Therapeutic Targets

open access: yesFrontiers in Bioscience-Landmark
As the global population ages, the risks associated with primary sarcopenia, including falls, fractures, functional decline, and frailty, are becoming increasingly apparent, all of which significantly impair the quality of life in older adults.

Extracellular vesicles circulating in young organisms promote healthy longevity

open access: yesJournal of Extracellular Vesicles, 2019
Parabiosis experiments in mice demonstrated that a young environment could partially rejuvenate multiple tissues of old organisms. However, the circulating mediators responsible of such effect have been elusive so far.

Structural modeling of NAD+ binding modes to PARP-1

open access: yesВавиловский журнал генетики и селекции, 2017
The nuclear protein poly (ADP-ribose) polymerase-1 (PARP-1) plays an important role in the signaling and repair of DNA. PARP-1 catalyses covalent binding of poly (ADP-ribose) polymers with itself as well as with other acceptor proteins using NAD+ as a ...

Assays for NAD+-Dependent Reactions and NAD+ Metabolites [PDF]

open access: yes, 2018
Nicotinamide adenine dinucleotide (NAD+) is an essential redox cofactor and signaling molecule that controls the activity of enzymes involved in metabolism, DNA repair, and cellular survival, such as the PARPs, CD38, and the sirtuins. Here, we describe three methods for measuring the activity of these enzymes: the etheno-NAD+ assay measures NAD ...

Impurity effect on low-temperature polarisation of the charge-density-waves in o-TaS$_3$

open access: yes, 1998
The temperature dependence of the low-temperature dielectric response is studied in o-TaS$_3$ samples doped by Nb, Se, and Ni and for nominally pure ones.

NAD replenishment restores mitochondrial function and thermogenesis in the brown adipose tissue of mice with obesity

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend A high‐fat diet (HFD) induces brown adipose tissue (BAT) whitening, mitochondrial dysfunction (damaged cristae, fragmentation), reduced NAD+ levels and impaired thermogenesis, leading to lower energy expenditure and metabolic inflexibility.

Arhitekture računala za adaptivno digitalno formiranje dijagrama usmjerenosti radarske antene

open access: yesVojnotehnički Glasnik, 1990
Kombiniranjem arhitekture sa slike 7 s principom računala upravljanog tokom podataka (data flow) (u literaturi je takva arhitektura poznata kao 'wavefront processor' ili polja valne fronte), dobivaju se dodatna poboljšanja i u smislu povećanja brzine i u
