background: systemic-onset juvenile idiopathic arthritis (sojia) is an autoinflammatory disease with complex genetic trait starts in children less than 16 years of age with fever and cutaneous rash. despite, the main genetic factors that may play a role in sojia have not yet been identified. high level of interleukin-1beta in the blood of sojia patients has been reported. the production and sec...

diadema setosum (leske, 1778), is one of the common echinoids widely distributed in the indo-west pacific ocean, where it occurs from the red sea, persian gulf and the east coast of africa to japan, australia and malaysia. to investigate the developmental basis of morphological changes in embryos and larvae, we documented the ontogeny of d. setosum in a controlled laboratory condition at the in...

A comparison of the community structure of juvenile hermatypic corals of 2 to 37 m depth at the fringing reefs of Curaçao between 1975 and 2005 shows a decline of 54.7% in juvenile coral abundance and a shift in species composition. Agaricia species and Helioseris cucullata, the most common juveniles in 1975, showed the largest decline in juvenile abundance (a 9 and 120 fold decrease in density...

Juvenile female rats show maternal-like behavior toward pups. The purpose of the following experiment was to investigate whether the HPA axis, through the use of early separation manipulations that alter HPA functioning in rats, plays a role in the juvenile response to foster pups. Female rats were early deprived or maternally separated for 5 hours daily from PND 2 to 14 and compared to animal ...

Although biologists routinely label animals as predators and prey, the ecological role of individuals is often far from clear. There are many examples of role reversals in predators and prey, where adult prey attack vulnerable young predators. This implies that juvenile prey that escape from predation and become adult can kill juvenile predators. We show that such an exposure of juvenile prey t...

Little is known about the youth who are deeply entrenched in our juvenile justice system. Why do some violent juvenile offenders alter their lives in a more positive direction after committing serious crimes? Why do some violent juvenile offenders continue to commit crimes? If research finds that there are different pathways that violent juvenile offenders take, then perhaps interventions used ...

the post-larval development of the majid crab Maja brachydactyla Balss, 1922 was studied using laboratoryreared larvae obtained from adult individuals collected in the ne atlantic. the morphology of the first juvenile stage is described in detail, while the most relevant morphological changes and sexual differentiation are highlighted for subsequent juvenile stages, until juvenile 8. the charac...

Most adult gastrointestinal stromal tumors (GIST) are thought to be caused by activating mutations in the KIT or PDGFRA gene. However, many juvenile GIST lack either mutation and are considered to develop with a different pathogenesis. To investigate the molecular characteristics of juvenile GIST, we analyzed the proteome difference in phosphorylated protein between adult and juvenile GIST. Ele...

OBJECTIVES Juvenile myositis is a rare and heterogeneous disease. Diagnosis is often difficult but early treatment is important in reducing the risk of associated morbidity and poor outcomes. Myositis specific autoantibodies have been described in both juvenile and adult patients with myositis and can be helpful in dividing patients into clinically homogenous groups. We aimed to explore the uti...

Survival rates of juvenile reptiles are critical population parameters but are difficult to obtain through mark-recapture programs because these small, secretive animals are rarely caught. This scarcity has encouraged speculation that survival rates of juveniles are very low, and we test this prediction by estimating juvenile survival rates indirectly. A simple mathematical model calculates the...
