Endocrine and regenerative cells in the midgut of Chagas' disease vector Triatoma vitticeps during different starvation periods.

The midgut of an insect has three main cell types, viz., digestive, endocrine and regenerative cells, and a relationship between cell morphology and blood meal has been suggested. This study evaluated the occurrence of the regenerative and endocrine cells in different regions of the midgut of female and male Triatoma vitticeps during different periods after a blood meal.

Effect of ultrasound and hyaluronidase on gynoid lipodystrophy type II - an ultrasonography study.

Introduction: The objective of this study was to evaluate the effect of ultrasound and the technique of phonophoresis with hyaluronidase in patients with cellulite edematous type II in the gluteal region.

Methods: Forty-two individuals, all females, were selected and randomly divided into two groups with 21 patients in each. Group I was treated with ultrasound without hyaluronidase and Group II was treated with ultrasound with hyaluronidase.

Digestive cells in the midgut of Triatoma vitticeps (Stal, 1859) in different starvation periods.

Triatoma vitticeps (Stal, 1859) is a hematophagous Hemiptera that, although being considered wild, can be found in households, being a potential Chagas' disease vector. This work describes the histology and ultrastructure of the midgut of T. vitticeps under different starvation periods.
