Morphological and Morphometric Characterisation of Selected Camarodont Sea Urchin (Echinoidea: Camarodonta) Pedicellariae (Paracentrotus lividus, Psammechinus miliaris and Echinus esculentus)

Acta Zoologica, EarlyView.
ABSTRACT Pedicellariae are small appendages on the surface of the echinoid test, involved in defence, cleaning, and locomotion. Pedicellariae in three species of camarodont sea urchins common in UK waters (Paracentrotus lividus [Lamarck, 1816], Psammechinus miliaris [P.L.S Müller, 1771] and Echinus esculentus [Linnaeus, 1758]) are the focus of this ...

Out in the cold? A review of Early Middle Palaeolithic settlements in northern Central Europe, age data and geological preconditions for site formation and preservation

Boreas, EarlyView.
The characteristics of settlement of Neanderthals in northern Central Europe during the earlier phases of the Middle Palaeolithic (Marine Isotope Stage 8–6) have been a matter of debate for decades, specifically regarding the population dynamics at such latitudes during the coldest phases. In this paper, we review the known archaeological record of the

Submerged geomorphic record of Quaternary palaeoshorelines: terraces and clinothems along a shelf‐edge in the Žirje Archipelago, Adriatic Sea

Boreas, EarlyView.
Numerous studies have shown that during the Quaternary there were substantial fluctuations in sea level in response to glacial–interglacial climate variability, reaching lowstand positions up to 134 m below the present sea level (b.s.l.). These fluctuations have had a strong influence on the morphology of shallow shelf seas, which preserve evidence of ...

Truncated drumlins and their implication for past sea level reconstructions

Boreas, EarlyView.
Coastal erosion of glacigenic sediments, particularly in the form of retreating drumlin bluffs, is a key process in paraglacial landscape evolution during periods of relative sea‐level (RSL) rise. As marine transgression reworks formerly subaerial glacial terrains, drumlins act as discrete sediment sources generating characteristic erosional and ...

Changes in land‐snail communities and steppe environments in the lower Rhône valley during the Lateglacial–Holocene transition

Boreas, EarlyView.
Land snail successions in the lower Rhône valley allow us to reconstruct the postglacial recolonization. From the Lateglacial period onwards, Mediterranean steppe communities appeared. The arrival of forest taxa was significantly delayed by aridity. The question of glacial refugia, both local and distant, primarily concerned Mediterranean species of ...

Pig islets for clinical islet xenotransplantation

Current Opinion in Nephrology and Hypertension, 2009
Allogeneic islet transplantation faces difficulties because organ shortage is recurrent; several pancreas donors are often needed to treat one diabetic recipient; and the intrahepatic site of islet implantation may not be the most appropriate one. Another source of insulin-producing cells, therefore, would be of major interest, and pigs represent a ...

Islet transplantation

Journal of Hepato-Biliary-Pancreatic Surgery, 2000
Recently, significant advances have been made in the number and purity of islets that can be retrieved from the human pancreas, thus enabling several centers to initiate or resume clinical trials of islet transplantation in type I diabetic patients. Although the success rate of islet transplantation is lower than that of pancreas transplantation in ...

Islet Autoantibodies

Current Diabetes Reports, 2016
Islet autoantibodies are the main markers of pancreatic autoimmunity in type 1 diabetes (T1D). Islet autoantibodies recognize insulin (IAA), glutamic acid decarboxylase (GADA), protein phosphatase-like IA-2 (IA-2A), and ZnT8 (ZnT8A), all antigens that are found on secretory granules within pancreatic beta cells.

Islet Yield Remains a Problem in Islet Autotransplantation

Archives of Surgery, 2002
For patients with chronic pancreatitis whose pain is inadequately controlled with opiate analgesia, surgical resection offers a good chance of symptomatic relief. However, the inevitable sequela is type 1 diabetes mellitus and its attendant long-term complications.
