Adding Value to Organic Milk Production Systems: opportunities for marketing meat and milk from dual purpose breeds [PDF]
, 2007 There is growing demand for and supply of organic milk. This results in more organic steers being produced. Many organic steer calves are sold to non-organic producers or are destroyed at birth. This is a serious issue for the organic dairy sector. This

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation
FEBS Letters, EarlyView.Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2010 The aim of this study was to evaluate the muscle fibre diameter of bulls (n = 136), heifers (n = 38) and steers (n = 18). The influence of age at slaughter, weight at slaughter, net daily weight gain, SEUROP meatiness and SEUROP fatness on the muscle ...

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS
FEBS Letters, EarlyView.We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

Cell wall target fragment discovery using a low‐cost, minimal fragment library
FEBS Letters, EarlyView.LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.
