Ayelen Tatiana Caimi, Federico Parra, Marcelo Alexander de Farias, Rodrigo Villares Portugal, Ana Paula Perez, Eder Lilia Romero, Maria Jose Morilla
Ultradeformable archaeosomes (UDA) are nanovesicles made of total polar archaeolipids (TPA) from the archaea Halorubrum tebenquichense, soybean phosphatidylcholine and sodium cholate (3:3:1w/w). Fresh dispersions of UDA including different type of antigens are acknowledged as efficient topical vaccination agents. UDA dispersions however, if manufactured for pharmaceutical use, have to maintain colloidal stability upon liposomicidal processes such as sterilization and lyophilization (SLRUDA), needed to extend shelf life during storage...

Hypertonicity causes severe clinical manifestations and is associated with mortality and severe short-term and long-term neurological sequelae. The main clinical syndromes of hypertonicity are hypernatremia and hyperglycemia. Hypernatremia results from relative excess of body sodium over body water. Loss of water in excess of intake, gain of sodium salts in excess of losses or a combination of the two are the main mechanisms of hypernatremia. Hypernatremia can be hypervolemic, euvolemic or hypovolemic. The management of hypernatremia addresses both a quantitative replacement of water and, if present, sodium deficit, and correction of the underlying pathophysiologic process that led to hypernatremia...

Table olives are widely consumed worldwide but, due to the presence of NaCl in fermenting brines, they contain high levels of sodium. A promising strategy to lower sodium content is the reduction or substitution of NaCl in brines with other chlorides. However, these procedures may impact safety, spoilage, as well as quality and technological properties, including the evolution and final composition of the fermenting microbiota. In the present work the effects of partially replacing NaCl with KCl in fermenting brines on the microbiological quality of Nocellara del Belice olives produced by Spanish style (Sivigliano) or Castelvetrano methods have been analyzed...

Skeletal co-morbidities in type 1 diabetes include an increased risk for fracture and delayed fracture healing, which are intertwined with disease duration and the presence of other diabetic complications. As such, chronic hyperglycemia is undoubtedly a major contributor to these outcomes, despite standard insulin-replacement therapy. Therefore, using the streptozotocin (STZ)-induced model of hypoinsulinemic hyperglycemia in DBA/2J male mice, we compared the effects of two glucose lowering therapies on the fracture resistance of bone and markers of bone turnover...

Central diabetes insipidus (CDI) results from a deficiency of arginine vasopressin (AVP) secretion. It is treated by replacement therapy with the synthetic AVP analogue desmopressin. To prevent heart failure in patients with CDI accompanied by cardiac dysfunction, controlling sodium and water intake is essential, using the minimum effective dose of desmopressin.

Paul Secombe, Chris Milne
Hyponatraemia-induced rhabdomyolysis is a rare, but reported phenomenon, particularly in patients with chronic schizophrenia on depot antipsychotics prone to psychogenic polydipsia. To the best of our knowledge, there are no reported cases of hyponatraemia-induced rhabdomyolysis complicated by oligo-anuric acute kidney injury (AKI) requiring continuous renal replacement therapy (CRRT). The initiation of CRRT is complicated in severe hyponatraemia, predominantly due to the need to avoid rapid changes in tonicity associated with rapid changes in sodium...

The epithelial sodium channel (ENaC) and the CFTR chloride channel critically regulate airway surface liquid by driving fluid absorption and secretion, respectively. Their functional interplay is complex and incompletely understood. ENaC is a heteromeric channel with three well characterised subunits (α, β, γ). In humans, an additional δENaC subunit exists in lung and several other tissues where it may replace the α-subunit to form δβγENaC. Little is known about the physiological role of δβγENaC and its possible interaction with CFTR...

Anhydrous compounds are crucially important for many technological applications, such as achieving high performance in lithium/sodium cells, but are often challenging to synthesize under hydrothermal conditions. Herein we report that a modified solvo-/hydro-fluorothermal method with fluoride-rich and water-deficient condition is highly effective for synthesizing anhydrous compounds by the replacement of hydroxyl groups and water molecules with fluorine. Two anhydrous phosphate germanium fluorides, namely, Na3[GeF4(PO4)] and K4[Ge2F9(PO4)], with chainlike structures involving multiple fluorine substitutions, were synthesized using the modified solvo-/hydro-fluorothermal method...
