OBJECTIVES: To study the role of angiogenesis and cyclooxygenase-2 expression in cartilaginous tumors and correlate these factors with prognosis.INTRODUCTION: For chondrosarcoma, the histological grade is the current standard for predicting tumor outcome.However, a low-grade chondrosarcoma can follow an aggressive course-as monitored by sequential
Abstract Background There is evidence that uric acid may have antioxidant and neuroprotective effects and might therefore alter the risk for neurodegenerative diseases such as dementia.So far, the relation between serum uric acid (SUA) levels or hyperuricemia and dementia remains elusive.Most studies focused on the disease or SUA levels.Effects of
The dairy industry produces large amounts of wastewater, including white and cleaning wastewater originating principally from rinsing and cleaning-in-place procedures.Their valorization into process water and non-fat milk solids, in the case of white wastewater, or the renewal of cleaning solutions could be achieved using pressure-driven membrane p
Amphibian populations are declining globally.In this scenario, detailed information on their ecology is crucial to determine the status and extinction risk of their populations and, therefore, better plan conservation activities.The Valcheta frog Pleurodema somuncurense is a Critically Endangered species, which is endemic to the Valcheta Stream, Pa
