Emission Enhancement

Photoactive macrocycles are obtained through coordination-driven self-assembly between calixarene L and Zn2+, Pd2+, Ag+, and Cd2+. Blue emission enhancement of L is observed upon assembly. M2L2Xn act as turn-off sensors for picric acid.

A recessive mutation has been recently described in the Mexican Axolotl, Ambystoma mexicanum; in which the heart forms structurally, but does not contract (Humphrey, 1968. Anat. Rec. 160:475). In this study, the fine structure of myocardial cells from normal (+/+; +/c) and cardiac lethal mutant (c/c) embryos at Harrison's stage 40 was compared. The hearts were fixed in a 0.1 M phosphate buffered formaldehyde-glutaraldehyde-picric acid-styphnic acid mixture and were post fixed in 0.1 M s-collidine buffered 1% osmium tetroxide. A detailed study of heart development in normal and mutant embryos from stages 25-46 will be described elsewhere.

: Bronchial asthma is one of the most common and severe diseases among children. The phenomenon of creatinuria (CU) in patients with bronchial asthma (BA) has been acknowledged for a relatively long time. Aims: The Aim of the research is to study the level of creatinuria, creatinemia, creatine kinase activity, and the concentration of calcium in biological medium (blood, saliva, urine) in children suffering from an intermittent and persistent form of asthma during the period of exacerbation. Material and methods:: The research consists of 102 children with asthma who were treated in inpatient department in Simferopol Clinic. The intermittent course of asthma was recorded in 49 children and a persistent course of asthma was recorded in 53 children. The subject of study was blood serum and daily urine of observed patients. The level of calcium in the biological medium was studied using the "Filisit" test kit (Dnipro) and the activity of the creatine kinase by test set "Lahma". The levels of creatine and creatinine were determined using a colorimetric method based on a color reaction with picric acid. Results and conclusion: : The analysis testifies that creatinuria in children with persistent BA is caused by the disorder of the phosphorylation process rather than the disorder of creatinin rephosphorylation synthesis, that is testified by the normal creatinine level. In children with persistent BA, there is а decrease of creatinine concentration in the blood serum and urine during the exacerbation period and early post exacerbation period. The low activity of creatinine kinase at the background of creatinine elimination is typical for the children in the phase of exacerbation of persistent form of BA, though its level remains to be sufficient for the synthesis of the necessary amount of creatinine phosphate. Conclusion: The processes of creatinuria and calciuria in children suffering from a persistent form of BA are interdependent, that is testified by the data of correlative analysis. In connection with this, it is possible to consider the change of calcium homeostasis in the pathogenesis of the disease as one of the causes of distributing the creatinine metabolism on the cellular level.

AbstractIn this work, strongly blue emitting Ce3+-activated BaAl2O4 nanophosphors were successfully synthesized by a sol–gel technique. The crystal structure, morphology, and microstructure of the nanophosphors have been studied by X-ray powder diffraction, field emission scanning electron microscopy, and high-resolution transmission electron microscopy. The photoluminescence spectra show the impact of concentration variation of Ce3+ on the photoluminescence emission of the phosphor. These nanophosphors display intense blue emission peaking at 422 nm generated by the Ce3+ 5d → 4f transition under 350 nm excitation. Our results reveal that this nanophosphor has the capability to take part in the emergent domain of solid-state lighting and field-emission display devices.
