Background:
Croton species are widely spread around the world, and present a varied
chemical composition distributed in many classes of secondary metabolites, such as terpenoides, alkaloids,
phenolic compounds and phenylpropanoids. These compounds can be obtained by different extraction
methods, and more recently, with supercritical fluids. The crude and isolated extracts may have
applications due to their biological activities in animals and humans.
Methods:
The text was written based on literature data from 1996 onwards.
Results:
The research showed in a concise way the botanical and taxonomic aspects of Croton and the
success of its application is in studies related to the biological activities of the plant parts. It was also
related to the chemical composition of its extracts and isolated compounds, obtained by many methods.
Conclusion:
In summary, the review feature studies reported the use of extracts and isolated Croton
compounds due to their biological effects with antioxidant, antimicrobial, anti-inflammatory, neuroprotective,
antitumor, anticancer, cytotoxic, insecticidal and allelopathic activities, with potential application
in food, cosmetics, pharmaceuticals, and agrochemicals products.
Introduction: Down syndrome individuals have different gait patterns, which include specific characteristics such as foot rotation asymmetry.
Objective: The aim of this study was to analyze the relationship between this asymmetry and the previous acquisition of hands-and-knees crawling in Down syndrome children, as well as the probable association of this gait to gender, ethnicity, comorbidities, physiotherapy, and occupational therapy interventions.
Methods: In this cross-sectional study, 361 children with or without foot rotation asymmetry were selected. An online questionnaire was administered to the parents or guardians of those children.
Results: Hands-and-knees crawling decreased the prevalence of foot rotation asymmetry in Down syndrome children. The longer it took for walking onset, the higher the prevalence of this asymmetry. Indeed, for each month of delay there was a 7% increase in prevalence. There was a significant relationship between orthopedic alterations in knees or flat feet and foot rotation asymmetry. There was no significance related to gender, ethnicity, other comorbidities, physiotherapy or occupational therapy interventions.
Conclusion: The findings in this study revealed that foot rotation asymmetry may be related to the acquisition of the motor skills described above, especially with regards to hands-and-knees crawling and walking onset.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
