Abstract

Coordination of uranium chemistry by multiligands has attracted attention as a way to obtain unique molecular structures and their possible use in environmental and nuclear waste disposal. In this work, mass spectrum with positive ions ［UO2(N3)n］+(n=0-4) as the dominant peaks generated by laser evaporation of uranium target with N2O as the carrier gas is reported. The associated quantitative calculations are carried out to explore structures and bonding interactions. The calculations show that N3 is bound to UO+2 as a radical and reveal that the bonding interaction in the whole system is found only between the first N3 ligand and uranium atom. Further localized molecular orbital analyses indicate the presence of multi-centered orbital delocalization in the system.

Abstract

We report two organic–inorganic hybrid thermochromic crystals, [(2A5MP)2CuCl4] (2A5MP = 2-amino-5-methylpyridine) (1) and [(2A4MP)2CuCl4] (2A4MP = 2-amino-4-methylpyridine) (2). Through hydrogen bond engineering optimization, the ferroelastic material 2 undergoes an isomorphic phase transition with a large thermal hysteresis of 36 K at 397 K/361 K. [ABSTRACT FROM AUTHOR]

Abstract

An ultrasensitive photoelectrochemical (PEC) aptasensor was originally designed by using ZnIn2S4/ReS2 as a photoactive material and AgInS2 as a signal amplifier. The signal amplifier AgInS2 was incubated on the terminal of H-DNA (immobilized on the ZnIn2S4/ReS2/FTO surface), leading to an enhanced photocurrent response. Then, due to the introduction of DNA2, the formation of a double-stranded structure caused AgInS2 to keep away from the electrode surface, and the photocurrent was reduced. In the presence of kanamycin, DNA2 was released from the system due to the competition relationship, and a restored photocurrent response was obtained. The combination of ZnIn2S4/ReS2 and AgInS2 accelerated the electron transfer and enhanced the separation efficiency of photogenerated electron–hole pairs, resulting in an improved performance of the PEC aptasensor, which was capable of accurate and sensitive detection of kanamycin in actual samples.

Abstract

ABSTRACT: Objective: To present a case of Langerhans cell histiocytosis (LCH) involving the pituitary and thyroid that was misdiagnosed as idiopathic diabetes insipidus (DI) and Hashimoto thyroiditis.Methods: The history, clinical findings, laboratory and imaging results, management, and follow-up of the case are presented, and the endocrine involvement is discussed.Results: A 50-year-old female with a 13-year history of DI and a 5-year history of progressive goiter with hypothyroidism had been initially diagnosed with idiopathic DI and Hashimoto thyroiditis. She also had a 10-year history of diabetes mellitus (DM). A partial thyroidectomy was conducted when the goiter caused dyspnea, and the postoperative pathological results suggested LCH. After a thorough examination, the diagnosis of LCH was confirmed, and the patient was treated with chemotherapy and radiotherapy. After the treatment, she went into persistent remission.Conclusion: LCH cases mainly presenting as endocrine disorders are very rare, and the diagnosis tends to be delayed or missed due to atypical clinical manifestations. Lesions or functional disorders of the pituitary and thyroid need to be differentially diagnosed against LCH of these organs. Appropriate therapy and long-term follow-up are necessary for the management of endocrine LCH.Abbreviations: CT computed tomography DI diabetes insipidus DM diabetes mellitus LCH Langerhans cell histiocytosis MRI magnetic resonance imaging TSH thyroid-stimulating hormone
