[Solid pseudopapillary neoplasm. Report of three cases and review of the literature].

Background: Solid pseudopapillary neoplasm, or Frantz-Gruber tumor, is a diagnostic challenge for the surgical pathologist. It is classified by the WHO as a malignant epithelial tumor of the pancreas, its prevalence is low, it occurs in only 1 to 2% of all malignant tumors of the pancreas, it usually affects mainly young women, its origin is still unclear, it is generally It presents as a solitary, encapsulated lesion, without invasion of peripancreatic tissues with rare cases of metastasis, which is why it is considered a low-grade malignant tumor by the WHO. The objective of this article is to present three clinical cases and to evaluate the epidemiology, clinical manifestations, morphology and immunohistochemical expression of the tumor in a review of the bibliography, as well as to compare it with the cases already reported on the subject.

An educational strategy for improving knowledge about breast and cervical cancer prevention among Mexican middle school students.

Introduction: Prevention programs have not achieved the expected results in preventing mortality from breast and cervical cancer in Mexico. Therefore, we propose a complementary strategy.

Methodology: An educational strategy for high school students in Mexico (2011-2013) was designed (longitudinal design, two measurements and a single intervention).

Effect of dietary intake of avocado oil and olive oil on biochemical markers of liver function in sucrose-fed rats.

Metabolic changes, along with cardiovascular and hepatic factors, are associated with the development of diseases such as diabetes, dyslipidemia, and obesity. We evaluated the effect of avocado oil supplementation (centrifuged and solvent extracted), compared with olive oil, upon the hepatic function in sucrose-fed rats. Twenty-five rats were divided into five groups: control (basal diet), a sucrose-fed group (basal diet plus 30% sucrose solution), and three other groups (S-OO, S-AOC, and S-AOS, indicating basal diet plus 30% sucrose solution plus olive oil OO, avocado oil extracted by centrifugation AOC or using solvent AOS, resp.

Avocado oil supplementation modifies cardiovascular risk profile markers in a rat model of sucrose-induced metabolic changes.

The purpose of this study was to evaluate the effects of avocado oil administration on biochemical markers of cardiovascular risk profile in rats with metabolic changes induced by sucrose ingestion. Twenty-five rats were divided into five groups: a control group (CG; basic diet), a sick group (MC; basic diet plus 30% sucrose solution), and three other groups (MCao, MCac, and MCas; basic diet plus 30% sucrose solution plus olive oil and avocado oil extracted by centrifugation or using solvent, resp.).
