Influence of heat treatments on the functionality of soy protein hydrolysates in animal cell cultures.

Soy protein hydrolysates enhance integral viable cell density (IVCD) and recombinant protein production (Immunoglobulin, IgG) in cell cultures, but their functionality varies from batch-to-batch. This is undesirable since it affects both quantity and characteristics of the recombinant proteins. It is hypothesized that the variability of hydrolysates is due to variations in meal and hydrolysate processing treatments.

High-Dose Intravenous Iron with Either Ferric Carboxymaltose or Ferric Derisomaltose: A Benefit-Risk Assessment.

The intravenous iron formulations ferric carboxymaltose (FCM) and ferric derisomaltose (FDI) offer the possibility of administering a large amount of iron in one infusion. This results in faster correction of anemia and the formulations being better tolerated than oral iron formulations. This triad of logistic advantages, improved patient convenience, and fast correction of anemia explains the fact that intravenous iron formulations nowadays are frequently prescribed worldwide in the treatment of iron deficiency anemia.

RNA polymerase II-binding aptamers in human ACRO1 satellites disrupt transcription .

Transcription elongation is a highly regulated process affected by many proteins, RNAs and the underlying DNA. Here we show that the nascent RNA can interfere with transcription in human cells, extending our previous findings from bacteria and yeast. We identified a variety of Pol II-binding aptamers (RAPs), prominent in repeat elements such as ACRO1 satellites, LINE1 retrotransposons and CA simple repeats, and also in several protein-coding genes.

[Hereditary and acquired transthyretin-mediated amyloidosis].

We describe three cases, two 70-year-old males with mainly cardiac symptoms and a 34-year-old male with gastro-intestinal and neurologic symptoms. Each patient was shown to have a distinctive type of transthyretin-mediated amyloidosis (ATTR). ATTR amyloidosis is a life-threatening disease characterised by the extracellular deposition of pathogenic transthyretin (TTR).

Development of a multi-position indentation setup: Mapping soft and patternable heterogeneously crosslinked polymer networks.

We present the development of a multi-position indentation setup capable of spatially mapping mechanically heterogeneous materials. A detailed description of the indentation instrumentation is first provided, emphasizing force sensitivity, noise reduction, and signal fidelity. We first present indentation experiments on soft hydrogels that are submerged in water and show how the large contributions to the measured force due to the air-water surface tension can be avoided.
