Abstract:
... Electroporation is the most widely used and efficient method to transform mycobacteria. Through this technique, fast- and slow-growing mycobacteria with smooth and rough morphotypes have been successfully transformed. However, transformation efficiencies differ widely between species and strains. In this study, the smooth and rough morphotypes of Mycobacteroides abscessus and Mycolicibacterium bru ...

Abstract:
... R-peak time (RPT) is an electrocardiographic parameter that represents the time taken for electrical activation to spread from the endocardium to the epicardium. In human medicine, right ventricular RPT is measured from lead V₁ to lead V₂, and left ventricular RPT from lead V₅ to lead V₆. The aim of the present study was to define RPT duration in a group of clinically healthy dogs with different t ...

Abstract:
... Groundnut (Arachis hypogaea L.) is essential to prepare numerous popular dishes across sub-Saharan Africa. However, groundnuts may contain hazardous aflatoxin levels. There is scant information on aflatoxin levels in Uganda and the causal agents of contamination in stored groundnut. High aflatoxin content hinders trading of groundnut and groundnut products in international markets, affecting Ugand ...

Some aquatic plants have terrestrial morphotypes that can produce seeds even in dry years. Here, we performed an experiment to compare germination patterns for seeds produced by aquatic and terrestrial morphotypes of Ranunculus peltatus subsp. saniculifolius over the course of five ...

Canids from the Upper Paleolithic site of Předmostí are central to debates concerning the domestication of dogs as two morphotypes were identified: Pleistocene wolf and Paleolithic dog (Germonpré et al., 2015a). In Prassack et al. (2020), we set out to determine whether specimens previously parsed into these two groups differed significantly in dental microwear textures, a proxy for diet. We did n ...

Phylogenetic analysis of mitochondrial COI and 16S rRNA genes revealed that this novel morphotype is polyphyletic, comprising four distinct major clades, with divergences up to 21.4% at COI. These clades are apparently morphologically cryptic, with no obvious shell di ...
