The present study was conducted to evaluate the status of the parasite fauna in Acipenser persicus at different development stages, in order to find prevention protocols for parasitic diseases in this valuable species. For this purpose, sampling from each sex breeder, 10 egg samples, 5-day-old larvae (n = 20), 20-day-old larvae (n = 80) and fingerling of A. persicus (n = 60) r...

Parkinson’s disease is a movement disorder that is characterized by degeneration of dopaminergic neurons of the substantia nigra, which is a part of the basal ganglia. The disease itself mostly has idiopathic causes and is to be distinguished from the symptomatic and the atypical Parkinsonism. The disease has a chronic-progressive course, whereas the life expectancy of those affected generally ...

Many women who give birth during their teenage years face lifetime disadvantages in health, social and economic domains. To develop effective policies to support these mothers, it is important understand how the disadvantage evolves over time target timing of any interventions. This paper focuses on health outcomes seeks determine role motherhood likely channels through which may contribute dis...

In many stage-structured species, different life stages often occupy separate spatial niches in a heterogeneous environment. Life stages of the giant flour beetle Tribolium brevicornis (Leconte), in particular adults and pupae, occupy different locations in a homogeneous habitat. This unique spatial pattern does not occur in the well-studied stored grain pests T. castaneum (Herbst) and T. confu...
