PURPOSE To report a case of autonomic, neurological and neuromuscular instability following methylene blue infusion for parathyroidectomy; to advance the argument for a diagnosis of serotonin syndrome; and to consider this diagnosis in previous, unexplained reports of adverse reactions amongst patients undergoing parathyroidectomy using methylene blue. CLINICAL FEATURES Methylene blue was adm...

A facile and universal method was developed to evaluate the relative water stability of porous MOFs and morphological evolution was achieved by controlling the volume ratio of DMF and H2O. The relative water stability of the studied MOFs is in the order HKUST-1 > MOF-505 ∼ UMCM-150 > NOTT-101 > DUT-23(Cu) > [Zn2(BPnDC)2(DABCO)] ∼ [Cu3(TPTrC)2(DABCO)] > MOF-5. In addition, DUT-23(Cu) [Cu6(BTB)4(...

Surface enhanced Raman scattering (SERS) and molecular fluorescence are used to probe the structure of a methylene blue monolayer adsorbed onto a sulfur-modified polycrystalline gold electrode. Changes in the wavelength of fluorescence for methylene blue on the gold electrode as compared to dilute solution indicate that the dye molecules' state of aggregation and electronic structure have been ...

Accidental ingestional poisoning among pediatric patients is a prevalent problem. In the absence of a well-designed national injury and poisoning surveillance system, cases often go unreported. Underreporting also occurs because many pediatric ingestions are trivial and not referred to a hospital for further medical management.1 To reduce health risks posed by common household products, emphasi...

Methylene blue is a safe and effective therapeutic agent used in a variety of different clinical settings, including as treatment for methemoglobinemia, reversing ifosfamide-induced encephalopa-thy, severe hepatopulmonary syndrome, and as a pressor during catecholamine-refractory septic shock (1). Of more relevance to neuropathologists, it has recently been experimentally tested as a dye in mul...

The in vitro viability, chemotaxis, and labeling stability of leukocytes labeled using 99mTc-exametazime stabilized with methylene blue were evaluated and compared with those obtained using nonstabilized 99mTc-exametazime. Methods: Two identical leukocyte populations, from 30 healthy donors, were labeled simultaneously using freshly prepared and 2-h-old stabilized 99mTc-exametazime. The followi...

The objective of this study was to measure discolouration using a digital camera on various types of clear orthodontic elastic modules, immersion solutions, and time periods to determine whether the cause of discolouration of these modules was due to simple staining, chemical degradation, or both. Three types of clear orthodontic elastomeric modules were investigated [Plastic ligatures (AO); Po...
