Liposarcomas are rare malignant neoplasms that originate in adipose tissue, most frequently in the retroperitoneum. Of all histological variants, differentiated liposarcoma is the most common and has the best prognosis. Diagnosis is established by imaging tests with or without the aid of biopsy. Treatment consists of complete resection of the tumour, which may or may not be accompanied by adjuvant therapy. We present the case of a 41-year-old patient with abdominal distension and weight loss, who was confirmed to have retroperitoneal liposarcoma by abdominal CT scan and underwent successful complete surgical resection. The patient recovered satisfactorily and remained free of recurrence during follow-up. It is concluded that diagnosis and therapy vary according to the characteristics of the tumour and its risk of recurrence, which is why it remains a multidisciplinary challenge to this d...

Passiflora edulis (passion fruit) is a plant whose fruit has a high biological value as it contains a large amount of polyphenols, the most important of which are flavonoids that act as powerful antioxidants against cancer and cardiovascular diseases. Recent studies have highlighted its antihypertensive role, even comparing it to hypotensive drugs. Arterial hypertension is one of the diseases that causes the greatest mortality and the most widespread worldwide. It is caused by endothelial dysfunction between vascular constrictor and relaxant factors, as a result of oxidative stress caused by the overproduction of reactive oxygen species. Flavonoids reduce the formation of free radicals by inhibiting NADPH oxidase; they also increase the activity of nitric oxide synthase (eNOS), increasing the vasodilation promoted by nitric oxide and providing a response capacity to endothelial damage by...
