RESUMO
We compared the effects of continuous exercise (CE) vs accumulated exercise (AE) training on CVD risk factors and heart of young male Wistar rats. The exercise training (ET) was performed in a swimming pool for 30-60 min/day, 5 days/week over 15 weeks. CE group performed the ET in a single long daily session (30-60 min), while AE group performed the ET at the same frequency, intensity, and duration of CE rats, but in three short bouts over the course of a day (10-20 min in three daily sessions). AE training was more efficient than CE in attenuating body and fat weight gain and inhibiting visceral adipocyte hypertrophy at the same food intake level. CE training was more efficient in improving systolic blood pressure, LDL/HDL cholesterol, and serum triglyceride. Both ET protocols increased heart function, decreased lipid peroxidation, and increased intracellular Hsp72 content in the heart. This work shows distinct beneficial effects of CE vs AE training suggesting that the prescription of one or other may be preferred to prevent the increase of a specific CVD risk factor.

Fibrolipomas are benign mesenchymal neoplasms of the fatty tissue rarely encountered in the oral cavity. They account for around 1% to 5% of all neoplasms affecting the mouth and occur as raised, slow-growing, painless lesions of normal or yellow coloration and uncertain etiology. In contrast, mucus retention cysts are epithelium-lined cavities originated from a salivary gland. They are also raised, asymptomatic, slow-growing lesions, located on the floor of the mouth, buccal mucosa and lips. This article reports a diagnostic and a surgical treatment of a rare fibrolipoma case associated with a mucus retention cyst located in the palate.

In the present paper, the effects of mouse serum and lymph in lymphocyte adhesion versus locomotion was distinguished using the same substrate (cellulose acetate filters) permissive (8 microns) and non-permissive (0.45 microns) to cells. The results presented suggest that serum and lymph have similar effects on lymphocyte adhesion, but behave differently in locomotion assays. The relevance of these findings to the understanding of the role of lymph proteins in the control of lymphocyte recirculation is discussed.
