BACKGROUND This study aimed to analyze differences in necrotic changes between cortical and cancellous bone in resection margins after segmental mandibulectomy for advanced mandibular osteoradionecrosis. METHODS Anteroposterior bone specimens from eleven patients who underwent segmental mandibulectomy with simultaneous free fibula flap reconstruction for advanced osteoradionecrosis were analy...
BACKGROUND Avascular necrosis of bone (osteonecrosis) can cause structural failure and subsequent deformation, leading to joint dysfunction and pain. Structural failure is the result of resorption of necrotic bone during revascularization, before new bone has formed or consolidated enough for loadbearing. Bone resorption can be reduced by bisphosphonates. If resorption of the necrotic bone coul...
BACKGROUND Intravascular ultrasound-derived virtual histology (VH IVUS) is used increasingly in clinical research to assess composition and vulnerability of coronary atherosclerotic lesions. However, the ability of VH IVUS to quantify individual plaque components, in particular the size of the destabilizing necrotic core, has never been validated. We tested for correlation between VH IVUS necro...
Catecholamine-induced heart injury in mice: differential effects of isoproterenol and phenylephrine.
The involvement of catecholamines in stress-induced heart injury is well documented. However, the contribution of adrenergic receptor types is less understood. Both the profile of plasma marker enzyme activities (lactate dehydrogenase-1 and aspartate transaminase) and the distribution and morphology of the lesions observed in tissue sections of adrenaline-injected mice resembled those of stress...
The Effect of a Mannanoligosaccharides (Biomos®) on Necrotic Enteritis Infection in Broiler Chickens
Apoptotic cells are significantly more immunogenic than necrotic cells, even though both forms are identical in antigenic content. When a combination of apoptotic and necrotic cells are used to immunize, the phenotype conferred by apoptotic cells, i.e., high immunogenicity, is dominant. However, necrotic cells are not immunosuppressive or tolerogenic. Apoptotic and necrotic cells are taken up b...
Necrosis is a type of cell death often caused by cell injury and is linked to human diseases including neuron degeneration, stroke, and cancer. Cells undergoing necrosis are engulfed and degraded by engulfing cells, their predators. The mechanisms by which necrotic cells are recognized and removed remain elusive. Here we comment on our recent findings that reveal new molecular mechanisms of nec...
