TbTim20 facilitates protein import at a low membrane potential in trypanosomes lacking the mitochondrial genome

open access: yesThe FEBS Journal, EarlyView.
Protein import into mitochondria relies on TIM complexes and the membrane potential. Trypanosoma brucei has a unique TIM complex, and the role of one subunit, TbTim20, has remained unclear. Here, we show that TbTim20 is essential in cells lacking mitochondrial DNA. The importance of TbTim20 increases as the membrane potential decreases.

New aspects in polygroup theory

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2020
The aim of this paper is to compute the commutativity degree in polygroup’s theory, more exactly for the polygroup PG and for extension of polygroups by polygroups, obtaining boundaries for them.

Comparative analysis of metabolic and functional cardiac alterations in diet‐ and genetically induced mouse models of cardiac dysfunction

open access: yesThe FEBS Journal, EarlyView.
Dietary and genetic stress trigger different routes to heart failure. In mice, a carbohydrate‐free high‐fat diet caused mitochondrial dysfunction and impaired energy production with preserved pumping function, while genetic obesity led to heart enlargement, fibrosis, and reduced function.

A systematic review and meta-analysis of radiotherapy planning studies comparing multi leaf collimator designs

open access: yesPhysics and Imaging in Radiation Oncology, 2018
Background and purpose: Several studies have investigated multi leaf collimator (MLC) leaf design. We performed a systematic review and meta-analysis of those studies to compare the impact of MLC leaf width used for different radiotherapy techniques ...

Comparative proteomics analysis of root and nodule mitochondria of soybean

open access: yesPlant, Cell &Environment, EarlyView.
Abstract Legumes perform symbiotic nitrogen fixation through rhizobial bacteroids housed in specialised root nodules. The biochemical process is energy‐intensive and consumes a huge carbon source to generate sufficient reducing power. To maintain the symbiosis, malate is supplied by legume nodules to bacteroids as their major carbon and energy source ...

Proteomic Analysis Reveals Accompanying Anion‐Dependent Changes of Cadmium Toxicity During Arabidopsis thaliana Development

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Cadmium (Cd) is a significant environmental pollutant with widespread detrimental effects on living organisms, making it a frequent subject of laboratory studies. However, different types of Cd salts are used to spike media, often without considering the possibility that accompanying anions may influence the effects of metal cations. Using two

Scientific photography and astronomy: Technology applied to understanding the universe

open access: yesMètode Science Studies Journal: Annual Review
In 1925, Edwin Hubble took the first step towards increasing the size of the known universe by several orders of magnitude using the precarious photographic methods available at the time: glass plates and photosensitive emulsions.

From Everyman to Hamlet: A Distant Reading

open access: yesRenaissance Studies, EarlyView.
Abstract The sixteenth century sees English drama move from Everyman to Hamlet: from religious to secular subject matter and from personified abstractions to characters bearing proper names. Most modern scholarship has explained this transformation in terms originating in the work of Jacob Burckhardt: concern with religion and a taste for ...
