Whole tomato lipidic extract improved sperm quality in obese rats induced by a high-carbohydrate diet.

Background: Obesity represents a risk in the development of metabolic and oxidative stress (OS), as well as in male infertility. There is still no pharmacological treatment for obesity-induced male infertility, but the use of natural antioxidants has been proposed as a treatment.

Objective: The aim of this work is to evaluate the effect of a whole tomato lipid extract on rats that decreased their fertility and spermatogenesis after being induced obese with a high carbohydrate diet.

Occult bronchogenic carcinoma masquerading as esophageal cancer. Case reports with recommendations for a change in reporting esophageal cytology.

We describe two patients with benign esophageal stricture in whom exfoliative esophageal cytologic features positive for squamous cell carcinoma is attributed to roentgenographically occult lung cancer. The discovery of alveolar macrophages within the esophageal washings of these patients prompted a retrospective analysis assessing the prevalence of esophageal washings contaminated by cellular material from the lower respiratory tract. Alveolar macrophages were observed in 11 of 28 patients (39%) and in 12 of 33 specimens (36%).
