The impact of public leadership on collaborative administration and public health delivery.

BACKGROUND: This research depicts the linkage of public leadership on public health delivery (PHD) and collaborative administration. The research is also focused to examine the effect of public leadership on public health delivery through the intervening variable of collaborative administration by using both social information processing theory and collaboration theory. METHODS: This research is based on quantitative method. Data was collected from 464 public hospital administration in the context of Pakistan. This study evaluated data using SPSS, AMOS, and PROCESS Macro. RESULTS: Public leadership has a positive profound effect on public health delivery and collaborative administration, and that collaborative administration significantly promotes public health delivery. The outcomes also exposed that public leadership has substantial influence on public health delivery through intervening collaborative administration. CONCLUSIONS: Whilst public leadership demonstrated positive outcomes on public health delivery and collaborative administration, there is a need for more rigor studies on collaborative governance leadership, collaborative ethics and collaborative norms in the public health service.

Protective role of 6-Hydroxy-1-H-Indazole in an MPTP-induced mouse model of Parkinson's disease.

This study aimed to explore the neuroprotective role of 6-hydroxy-1H-indazole on dopaminergic neurons in a 1-methyl-4-phenyl-1, 2, 3, 6-tetrahydropyridine (MPTP) mouse model of Parkinson's disease (PD). Forty 12-week-old C57BL/6 male mice were were randomized divided into 4 groups. Mice were treated with 2mg/kg and 4mg/kg 6-hydroxy-1H-indazole (i.p.) 1d before the initiation of MPTP administration (30mg/kg), and the 6-hydroxy-1H-indazole were daily injected half an hour before MPTP treatment in the following 5 days. The MPTP group was given normal saline on day 1 (i.p.), followed by 30mg/kg MPTP treatment in the following 5 days. Control group received an equivalent volume of normal saline. Ten days after the final injection of MPTP, the mice were killed. The results showed that MPTP decreased the dopaminergic neurons in the substantia nigra and dopamine in the striatum, downregulated the expression of tyrosine hydroxylase (TH), induced the impairment of behavior and hyperphosphorylation of tau, However, 6-hydroxy-1-H-indazole decreased the loss of dopaminergic neurons, increased dopamine concentration and TH expression, alleviated the behavioral damage and level of phosphor-tau in the MPTP-induced model of PD in C57BL/6 mice. These findings showed that 6-hydroxy-1-H-indazole-mediated neuroprotection was related to the inactivation of tau. In addition, 6-hydroxy-1-H-indazole may be a potential drug candidate for PD.
