RESUMO
Nursing professional development practitioners are integral leaders who continue to seek tangible ways to show their value. A tool was designed to capture workload based upon the scope and standards of nursing professional development practice and successfully captured the workload of over 200 practitioners. The measures used in this project can serve as a guide for others to describe nursing professional development practitioner workload.

A series of 4H-1,2,3-thiadiazolo[5,4-b]indoles were synthesized by novel tandem of oxidative cyclization of 3-alkoxycarbonylhydrazonoindoline-2-thiones, 1,5-H-shift and elimination of tert-butoxy(ethoxy)carbonyl group. The simple method for their modifications by the reactions with electrophilic agents were elaborated and as a result of the synthetic investigation a number of N-alkyl-, N-acyl- and N-sulfonyl-4H-1,2,3-thiadiazolo[5,4-b]indoles were prepared in good yields. Preliminary biological tests for the three examples of synthesized compounds with different substituents at the nitrogen atom indole ring have shown that the biological behavior of the investigated 1,2,3-thiadiazolo[5,4-b]indoles is substantially directed by this structural fragment.

When grown in short day conditions and at low light, leaves of Arabidopsis plants with mutations in the genes encoding two plastidial ATP/ADP transporters (so-called null mutants) spontaneously develop necrotic lesions. Under these conditions, the mutants also display light-induced accumulation of H(2)O(2) and constitutive expression of genes for copper/zinc superoxide dismutase 2 and ascorbate peroxidase 1. In the light phase, null mutants accumulate high levels of phototoxic protoporphyrin IX but have only slightly reduced levels of Mg protoporphyrin IX. The physiological changes are associated with reduced magnesium-chelatase activity. Since the expression of genes encoding any of the three subunits of magnesium-chelatase is similar in wild type and null mutants, decreased enzyme activity is probably due to post-translational modification which might be due to limited availability of ATP in plastids during the night. Surprisingly, the formation of necrotic lesions was absent when null mutants were grown either in long days and low light intensity or in short days and high light intensity. We ascribe the lack of lesion phenotype to increased nocturnal ATP supply due to glycolytic degradation of starch which may lead to additional substrate-level phosphorylation in the stroma. Thus, nocturnal import of ATP into chloroplasts represents a crucial, previously unknown process that is required for controlled chlorophyll biosynthesis and for preventing photooxidative damage.
