The optimized experimental parameters of degradation obtained with a four-factor at three-level orthogonal array experimental design L18(3) were temperature, rotation speed, inoculum size and liquid level by Corynebacterium variabile in the shaking bottle as 33 , 22h after shaking at the same temperature and 120 rpm for 14h, 4%, 80mL in 150mL triangle bottle, respectively. Among four factors, l...

A preterm female infant born at 27 weeks of gestation with a birth weight of 990 g developed acute hypotonia, apnea, hypotension and bradycardia mimicking septic shock syndrome at 14h after birth. Laboratory tests indicated a severe hypermagnesemia of 45 mg/dL. The renal function, complete blood count and maternal blood concentrations of magnesium were normal, and the blood cultures were negati...

A simple and efficient procedure for the synthesis of 14-aryl-14H-dibenzo[a,j ]xanthene derivatives through one-pot condensation of 2-naphthol with aryl aldehydes in the presence of niobium pentachloride is described. The reactions were carried out using 25 mole % of NbCl5, at ambient temperature, and in acceptable reaction times, affording excellent yields of the products. c © 2014 Institute o...

Scintillation properties of 14-phenyl-14H-dibenzo[a,j]xanthenes (called material A) is studied. Cyclohexan is used as a solvent, whilst Anthracene and Naphthalene are used as secondary solutes. The response of the scintillator to low energy Gamma-rays is detectable. Our study shows that the addition of material A (0.01 mol L ) to the solution of Anthracene-Naphthalene-Cyclohexan, improves the d...

Polyethyleneglycol bound sulfonic acid (PEG-OSO₃H), a chlorosulphonic acid-modified polyethylene glycol was successfully used as an efficient and eco-friendly polymeric catalyst in the synthesis of 14-aryl/heteroaryl-14H-dibenzo[a,j]xanthenes obtained from the reaction of 2-naphthol and carbonyl compounds under solvent-free conditions with short reaction times and excellent yields. The biologic...

The structure of the title compound, Na(6)(Mo(7)O(24))·14H(2)O, has been redetermined [Sjöbom & Hedman (1973). Acta Chem. Scand.27, 3673-3674] and the hydrogen atoms have been located. The Na(+) cations adopt distorted octa-hedral geometries and the structure of the [Mo(7)O(24)](6-) anion is consistent with those of other hepta-molbydates. In the crystal, numerous O-H⋯O hydrogen bonds help to e...

a convenient and efficient procedure for the synthesis of 14-aryl or alkyl-14h-dibenzo[a,j]xanthenes by condensation of 2-naphthol and aldehydes in the presence of methylimidazolium hydrogensulfate, as a brönsted acidic ionic liquid ([hmim]hso4), is described. both aromatic and aliphatic aldehydes reactedeasily to afford the corresponding 14-aryl or alkyl-14h-dibenzo[a,j]xanthenes in good yield...

Both aromatic and aliphatic aldehydes reacted easily to afford the corresponding 14-aryl or alkyl-14H-dibenzo[a,j]xanthenes in good yiel...

To assess the acute effects of nasal continuous positive airway pressure (CPAP) on the 24-hour blood pressure and the secretion of catecholamines in urine and plasma, we investigated the changes in the 24-hour blood pressure and urinary and plasma concentrations of epinephrine (E) and norepinephrine (NE) in 26 men with obstructive sleep apnea (OSA) with and without nasal CPAP. Nasal CPAP result...
