“…Also, these studies were rarely focused on acidic conditions partly due to the complication of gluconic acid lactonization at low pC H . Even though a few studies for Ln(III)/gluconate systems [3,4,6] were conducted in acidic solutions, the results are not consistent. Since waste processing may require the thermodynamic data of lanthanides and actinides over a broad pC H range (from acidic to basic), we have studied the complexation of gluconate with Nd(III) at relatively low pC H (2.5-4.5) with consideration of the lactonization effect.…”

“…Kostromina [3] and Giroux et al [6] agreed on the formation of 1:1 and 1:2 Ln(III) gluconate complexes, but the values for the 1:2 complex do not agree. Panda and Patnaik [4] considered only a 1:1 Ln(III) gluconate complex under their experimental conditions. These differences may be partially explained by lactonization, which the authors did not consider.…”

“…Representative literature data [3,4,6] for gluconate complexation with lanthanides in acidic solutions are listed in Table 1, including complexation patterns and stability constants, which were determined by potentiometry. The results indicate divergent interpretations of the observed Ln(III)/gluconate behavior under similar experimental conditions.…”

“…To be consistent with the notations in the literature, gluconic acid, gluconate and glucono-lactone are denoted by HGH 4 (aq), GH 4 −1 and L(aq), respectively, where the first H refers to the carboxylic acid hydrogen and H 4 refers to the four hydrogens on the secondary alcohols [12,13]. Also, glycolic acid (CH 2 OHCOOH) was used for comparison.…”

“…Several studies on the complexation of gluconic acid with lanthanides [1][2][3][4][5][6][7][8] and actinides [9,10] can be found in the literature. Stability constants were reported in these studies, but no other thermodynamic properties (e.g., enthalpies) were provided.…”

Purpose While typically affecting older adults and immunocompromised individuals, herpes zoster ophthalmicus (HZO) has been reported with varying manifestations and complications in children. In this review, we evaluate reported cases of pediatric HZO in the literature and discuss the epidemiology, risk factors, clinical presentation, treatment and outcomes. Methods A literature search on PubMed, Scopus, and Web of Science databases was performed using the terms “pediatric herpes zoster ophthalmicus” and “herpes zoster ophthalmicus children.” Publications that were not specific to HZO or pediatric populations were excluded, as were publications that were not available to review or not published in the English language. Results Fifty-seven reports describing 130 cases of HZO or HZO-related complications were reviewed. Major risk factors for pediatric HZO included intrauterine exposure to varicella or primary varicella infection at a young age; HZO also occurred in patients who had received varicella vaccination. Both healthy and immunocompromised children were affected, with the majority of affected children being immunocompetent. The diagnosis of HZO is primarily clinical. Children appear to have good vision recovery and resolution of symptoms if they are treated promptly and if they adhere to treatment regimens, except for irreversible vision loss related to uncommon complications such as optic neuritis. Conclusion HZO occurs in both healthy and immunocompromised children. Recognizing this treatable condition is essential for reducing ocular and systemic morbidity. Long-term follow-up and assessments of the impact on health in adulthood are lacking. More systematic study is needed to determine the incidence of HZO in children and appropriate diagnostic and treatment protocols for the care of pediatric patients with HZO.

Formation of mono- and binuclear neodymium(iii)–gluconate complexes in aqueous solutions in the pH range of 2–8

The complex formation between Nd(iii) and d-gluconate (Gluc) is of relevance in modelling the chemical equilibria of radioactive waste repositories. In the present work, the formation of NdGlucH complexes at 25 °C and pH = 2-8 was studied via spectrophotometry, potentiometry, freezing point depression, conductometry and NMR spectroscopy. In addition to the four mononuclear complexes (pq-r = 110, 120, 130 and 11-2), the formation of two binuclear, so far unknown complexes (pq-r = 23-2 and 24-2) was revealed. Between pH = 5.5 and 7, with the increasing metal ion and ligand concentrations, the NdGlucH species becomes progressively predominant. Under the conditions characteristic of waste repositories, however, the formation of these complexes can be neglected. Regarding the binding sites of Gluc, C2-OH and C3-OH groups, in addition to the carboxylate ion, were identified from H andC spectroscopic measurements. Above pH = 6, the metal-ligand interactions became stronger implying the formation of deprotonated complexes involving the C2-OH group, while the displacement of the second proton at the C3-OH is also possible. The metal ion induced deprotonation of the ligand was confirmed by DFT calculations.
