Ornithodoros fonsecai is an argasid tick that is endemic to Brazil. The autogeny (the oviposition without a blood meal) can be facultative or obligatory in female ticks of the family Argasidae. The present study reports new records on the facultative autogeny among populations of O.

Background: This study evaluates the effects of ozone on hard and soft tissue healing when a free tissue flap is used to close wound areas lacking primary closure over autogenous grafted sites.
Methods: In our study, 24 male Wistar rats were divided into four groups: two control groups and two ozone-treated groups. All rats underwent the same surgical procedure.

regenerates one head when cut, but how forces shaping the head are coordinated remains unclear. Soft compression of 's head-regenerating tissues induces the formation of viable, two-headed animals. Compression creates new topological defects in the supracellular orientational order of muscular actin fibers, associated with additional heads.

Cell-generated forces play a critical role in driving and regulating complex biological processes, such as cell migration and division and cell and tissue morphogenesis in development and disease. Traction force microscopy (TFM) is an established technique developed in the field of mechanobiology used to quantify cellular forces exerted on soft substrates and internal mechanical tissue stresses. TFM measures cell-generated traction forces in 2D or 3D environments with varying mechanical and biochemical properties.

Dorsal closure is a process that occurs during embryogenesis of . During dorsal closure, the amnioserosa (AS), a one-cell thick epithelial tissue that fills the dorsal opening, shrinks as the lateral epidermis sheets converge and eventually merge. During this process, both shape index and aspect ratio of amnioserosa cells increase markedly.
