The lack of support for a retroflexed endoscope in the peritoneal cavity makes it hard to reach remote structures and makes vigorous retraction of tissues and organs difficult.
TBI results from mechanical forces such as an object striking the head, or from rapid acceleration and deceleration forces that cause vigorous movement, and thereby tissue deformation, of brain tissue within the skull.
By the final harvest (42 days post-anthesis; DPA) symptoms (leaf yellowing) of senescence had begun to appear in the oldest leaves, while younger tissue remained vigorous.
Selection pressures placed on the human genome over hundreds of thousands of years of early hominid evolution appear to have favored a vigorous early response to tissue injury and/or an infectious challenge.
The differences in expression levels between these tissues may therefore indicate that metabolic activity is more vigorous in newly generated tissues.
Both stromal capillary and choroidal epithelial tissues mounted vigorous, yet different, changes in expression of numerous genes over the time course analyzed - including those encoding adhesion molecules, cytokines, chemokines, statins, interleukins, T cell activation markers, costimulatory molecules, cyclooxygenase, pro-inflammatory transcription factors and pro-apoptotic markers.
Most cancers arise from genetic or epigenetic damage in renewable tissues, resulting in vigorous cell proliferation and survival on the basis of impaired apoptosis.
Fin tissue was dissociated by vigorous shaking in 1 mg mL−1 collagenase/dispase solution (Roche) for 20 min at 37 °C.
Incubation in a 37 °C water bath (15 min was selected with this batch of enzyme) was followed by vigorous shaking by hand to disrupt tissue structure.
Parasite proliferation is usually accompanied by a granulomatous host reaction, including vigorous synthesis of fibrous and germinative tissue in the periphery of the metacestode, but also necrotic changes centrally.
