- - Structural, functional and nutritional properties of protein recovered from brown seaweed, S. latissima with alkaline solubilization/isoelectric precipitation as a function of different post-harvest stabilization methods were studied. The latter included freezing at −20 °C/-80 °C, oven-drying, sun-drying, freeze-drying and ensilaging. Also, the efficacy of freeze/thaw-aided precipitation (F/T) in improving protein recovery of the process was evaluated. The freeze-dried, oven-dried, and −20 °C frozen seaweeds resulted in significantly higher protein yield than the −80°C-frozen, sun-dried and ensiled biomasses. F/T increased protein precipitation and doubled total protein yield. Sun-drying and −20°C-freezing caused extensive protein degradation as revealed by SDS-PAGE and HP-SEC, while oven-drying altered the seaweed protein structure with less α-helices. Functional properties of the seaweed proteins were remarkably affected by stabilization condition and F/T, but nutritional value of the proteins was only dependent on stabilization method. Thus, to efficiently recover seaweed proteins, its post-harvest stabilization condition must be carefully chosen based on the final application of the proteins. © 2019 The Authors

Sensory receptor repertoire in cyprid antennules of the barnacle Balanus improvisus

- - Barnacle settlement involves sensing of a variety of exogenous cues. A pair of antennules is the main sensory organ that the cyprid larva uses to explore the surface. Antennules are equipped with a number of setae that have both chemo- and mechanosensing function. The current study explores the repertoire of sensory receptors in Balanus improvisus cyprid antennules with the goal to better understand sensory systems involved in the settling behavior of this species. We carried out transcriptome sequencing of dissected B. improvisus cyprid antennules. The generated transcriptome assembly was used to search for sensory receptors using HMM models. Among potential chemosensory genes, we identified the ionotropic receptors IR25a, IR8a and IR93a, and several divergent IR candidates to be expressed in the cyprid antennules. We found one gustatory-like receptor but no odorant receptors, chemosensory or odorant-binding proteins. Apart from chemosensory receptors, we also identified 13 potential mechanosensory genes represented by several transient receptor potential channels (TRP) subfamilies. Furthermore, we analyzed changes in expression profiles of IRs and TRPs during the B. improvisus settling process. Several of the sensory genes were differentially expressed during the course of larval settlement. This study gives expanded knowledge about the sensory systems present in barnacles, a taxonomic group for which only limited information about receptors is currently available. It furthermore serves as a starting point for more in depth studies of how sensory signaling affects settling behavior in barnacles with implications for preventing biofouling. © 2019 Abramova et al.

Role of apolipoprotein C-III overproduction in diabetic dyslipidaemia

- - Aims: To investigate how apolipoprotein C-III (apoC-III) metabolism is altered in subjects with type 2 diabetes, whether the perturbed plasma triglyceride concentrations in this condition are determined primarily by the secretion rate or the removal rate of apoC-III, and whether improvement of glycaemic control using the glucagon-like peptide-1 analogue liraglutide for 16 weeks modifies apoC-III dynamics. Materials and Methods: Postprandial apoC-III kinetics were assessed after a bolus injection of [5,5,5- 2 H 3 ]leucine using ultrasensitive mass spectrometry techniques. We compared apoC-III kinetics in two situations: in subjects with type 2 diabetes before and after liraglutide therapy, and in type 2 diabetic subjects with matched body mass index (BMI) non-diabetic subjects. Liver fat content, subcutaneous abdominal and intra-abdominal fat were determined using proton magnetic resonance spectroscopy. Results: Improved glycaemic control by liraglutide therapy for 16 weeks significantly reduced apoC-III secretion rate (561 ± 198 vs. 652 ± 196 mg/d, P = 0.03) and apoC-III levels (10.0 ± 3.8 vs. 11.7 ± 4.3 mg/dL, P = 0.035) in subjects with type 2 diabetes. Change in apoC-III secretion rate was significantly associated with the improvement in indices of glucose control (r = 0.67; P = 0.009) and change in triglyceride area under the curve (r = 0.59; P = 0.025). In line with this, the apoC-III secretion rate was higher in subjects with type 2 diabetes compared with BMI-matched non-diabetic subjects (676 ± 208 vs. 505 ± 174 mg/d, P = 0.042). Conclusions: The results reveal that the secretion rate of apoC-III is associated with elevation of triglyceride-rich lipoproteins in subjects with type 2 diabetes, potentially through the influence of glucose homeostasis on the production of apoC-III. © 2019 John Wiley & Sons Ltd

- Nitzschia biundulata sp. Nov. a new sea ice diatom (bacillariophyceae) from the ross sea, Antarctica

Tidskriftsartikel (refereegranskat)abstract
- - A new marine diatom species, Nitzschia biundulata is described. This species was collected and isolated from the ice cover in the Amundsen Sea, Antarctica during the Austral summer, 2011. The description is based on light and scanning electron microscopes examination as well as molecular analysis including 18S SSU rRNA and rbcL. Morphologically, N. biundulata is characterized by having two extensions of the valve margin in a form of two unequal undulations that are not seen in other taxa of the genus. Molecular sequence data indicated similarity with several Nitzschia species such as Nitzschia apiculata, N. palea, N. capitellata as well as Bacillaria paxillifer. Interestingly, large similarity was found with endosymbiont diatom associated with the dinophyte Peridinium balticum. A comparison with the most related species is provided. © 2019 J.

Reflections on knowledge transfer within traditional crafts
- 2016
-
Ingår i: Studia vernacula. - 1736-8138 .- 2504-6748. ; :7
-
Tidskriftsartikel (refereegranskat)abstract
- This article concerns knowledge transfer within traditional crafts. Setting out from documented encounters with craftspeople, enterprises and craft communities, the objective is to reveal different notions of traditional craftsmanship and how ways of thinking about crafts affect knowledge transfer. The article focuses on a few general questions derived from surveys and interviews. What is the nature of craftsmanship? What constitutes a tradition? How can this knowledge be documented and passed on in a meaningful way? Particular interest is placed on relations between amateur communities and professional trades, between crafts and the academic knowledge system, and furthermore between crafts and heritage conservation.
