BACKGROUND: Exchange blood transfusion (EBT) is a form of whole blood transfusion in which the total blood volume is replaced within a few hours. In perinatal and neonatal medicine, EBT is most often used in the management of severe anaemia or severe hyperbilirubinaemia in the first week of life. Hypocalcaemia, one of the common morbidities associated with EBT, is thought to arise from the chelating effects of the citrate commonly used as an anticoagulant in the donor's blood. This disorder manifests with muscular and nervous irritability and cardiac arrhythmias...

Context • Intravenous ascorbic acid (IVAA) has been used extensively as part of the management plan for cancer patients in various medical clinics throughout the United States. The current research team has evaluated its effectiveness in patients with cancer as part of an ongoing research program. However, no data are available that support the chemical stability of intravenously injectable ascorbic acid (AA) to ensure its safety and efficacy in that patient population. Its clinical use as well as its use in research conducted in US Food and Drug Administration-approved clinical trials require validation of its stability...

The calcium complexation and acid-base properties of α-d-isosaccharinate (Isa(-)) in neutral and in (hyper)alkaline solutions have been investigated via potentiometric titrations, multinuclear NMR, ESI-MS and quantum chemical calculations. Isa(-) is the primary alkaline degradation product of cellulose, and may be present in radioactive waste repositories and therefore, it could contribute to the mobilization of radioactive nuclei. Because of its limited availability, d-gluconate (Gluc(-)) is commonly used as a structural and functional model of Isa(-)...

Objective The selective arterial secretagogue injection (SASI) test is considered indispensable for the accurate localization of insulinoma. However, the optimum timing of the post-injection evaluation is controversial, as some studies recommend 60 seconds (SASI [(60 sec]) while others support 120 seconds (SASI [120 sec]). The aim of this study was to determine the optimum timing for the SASI test evaluation for insulinoma localization. Methods Thirteen patients with surgically proven insulinoma were studied retrospectively...

BACKGROUND: Perioperative fluid strategies influence clinical outcomes following major surgery. Many intravenous fluid preparations are based on simple solutions, such as normal saline, that feature an electrolyte composition that differs from that of physiological plasma. Buffered fluids have a theoretical advantage of containing a substrate that acts to maintain the body's acid-base status - typically a bicarbonate or a bicarbonate precursor such as maleate, gluconate, lactate, or acetate...

A normal serum calcium level is 8 to 10 mg/dL. The diagnosis of hypercalcemia (ie, levels 10.5 mg/dL or greater) should be confirmed with an albumin-adjusted or ionized calcium level. The two most common causes of hypercalcemia are hyperparathyroidism and malignancy. Drugs, notably lithium and thiazide diuretics, also can cause hypercalcemia. Patients with severe or symptomatic hypercalcemia should be treated initially with hydration to decrease calcium levels. The evaluation should include a parathyroid hormone (PTH) level...

Nick Schneider, Dietmar Stephan
This article presents a combined use of a retarder (d-gluconic acid) and an alkaline activator (sodium hydroxide) in a binder system based on ground granulated blast-furnace slag. The properties of the retarder are extending the dormant hydration period and suppressing the generation of strength-giving phases. Different retarder concentrations between 0.25 and 1.00 wt.% regulate the intensity and the period of the retardation and also the characteristics of the strength development. The activator concentration of 30 and 50 wt...

We report the case of a 25-year-old female presenting to the emergency department after committing suicide by ingesting 100 mg amlodipine. The patient was initially treated with intravenous fluids, calcium gluconate, catecholamines and glucagone without effect. The clinical condition of the patient improved quickly and dramatically on the 20th minute of intravenous lipid emulsion (ILE) therapy. Different treatment methods have been developed for calcium channel blocker intoxication over the last years. Among these, lipid emulsion therapy has risen over the last decade as a salvation in cases which do not respond to other treatments...

Platelet-rich plasma (PRP) contains growth factors which positively affect cell proliferation, cell differentiation, chemotaxis and intracellular matrix synthesis. All these processes are involved in wound healing and tissue regeneration; thus, PRP as a source of growth factors can be used in periodontal regenerative therapies. The purpose of the present study was to assess the effect of various concentrations of activated and non-activated PRP on proliferation of osteoblasts and fibroblasts in vitro. PRP was obtained from three healthy volunteers...

Cartilage tissue engineering based on biomimetic scaffolds has become a rapidly developing strategy for repairing cartilage defects. In this study, a biphasic CAN-PAC hydrogel for osteochondral defect (OCD) regeneration was fabricated based on the density difference between the two layers via a thermally reactive, rapid cross-linking method. The upper hydrogel was cross-linked by CSMA and NIPAm, and the lower hydrogel was composed of PECDA, AAm and PEGDA. The interface between the two layers was first grafted by the physical cross-linking of calcium gluconate and alginate, followed by the chemical cross-linking of the carbon-carbon double bonds in the other components...

Maintenance of physiological levels of intracellular and extracellular calcium is essential for life. Increased intracellular calcium levels are involved in cell death (apoptosis and necrosis) and are associated with positive responses in the Comet assay in vitro. In addition, high calcium and vitamin D intakes were reported to induce apoptosis in adipose tissue in obese mice and to increase DNA-migration in the Comet assay. To investigate increased serum concentration of calcium as a potential confounding factor in the regulatory Comet assay in vivo, we induced mild hypercalcemia in male Wistar rats by 3-day continuous intravenous infusion of calcium gluconate and performed the Comet assay in the liver in line with regulatory guidelines...
