We simulated dynamic rupture propagation along a branched fault, which is partially segmented by a slit. This is an analogy of a strike slip fault, which displays a jog structure on the ground surface but forms a continuous system at depth. We observed that rupture directivity can significantly change due to the existence of the fault slit and that the relative location of the slit to the hypoc...
Seismological observations of the 2012 moment magnitude 8.6 Sumatra earthquake reveal unprecedented complexity of dynamic rupture. The surprisingly large magnitude results from the combination of deep extent, high stress drop, and rupture of multiple faults. Back-projection source imaging indicates that the rupture occurred on distinct planes in an orthogonal conjugate fault system, with relati...
BACKGROUND Rupture of the symphysis pubis during vaginal delivery is a rare but debilitating complication. Factors contributing to rupture are poorly defined. CASE A healthy primigravida suffered a rupture of her symphysis pubis during an otherwise uncomplicated vaginal delivery. She experienced significant pain and difficulty walking for 6 months after the injury. Her 5-cm symphyseal separat...
Repeated rounds of nuclear envelope (NE) rupture and repair have been observed in laminopathy and cancer cells and result in intermittent loss of nucleus compartmentalization. Currently, the causes of NE rupture are unclear. Here, we show that NE rupture in cancer cells relies on the assembly of contractile actin bundles that interact with the nucleus via the linker of nucleoskeleton and cytosk...
By its very nature, rupture of the atherosclerotic plaque is difficult to study directly in humans. A good animal model would help us not only to understand how rupture occurs but also to design and test treatments to prevent it from happening. However, several difficulties surround existing models of plaque rupture, including the need for radical interventions to produce the rupture, lack of d...
Spontaneous rupture of the oesophagus may occur either transmurally or intramurally. The symptoms, signs, clinical course, treatment and prognosis differ in the two types. Transmural rupture is generally regarded as a serious condition, usually requiring operative treatment and having a high morbidity and mortality. Intramural rupture is a much more benign condition, is treated non-operatively ...
A pathologic splenic rupture refers to a rupture without trauma. A splenic rupture as the initial manifestation of acute myeloid leukemia is extremely rare. In this study, we described a rare case of acute myeloid leukemia presenting principally as an acute abdomen due to a pathologic splenic rupture in a 35-year old male patient. We can assert that a pathologic splenic rupture in hematologic d...
Hydatid cyst liver rupture into the biliary tree may involve the common hepatic duct, lobar biliary branches, the small intrahepatic bile ducts or rarely the gallbladder. Rupture can be occult or frank. A frank intrabiliary rupture of hepatic hydatid cyst is a rare but serious event. The authors are reporting a case of concomitant rupture of hydatid cyst of liver into right hepatic duct and the...
Uterine rupture is the most serious complication for women undergoing trial of labor (TOL) after prior cesarean delivery. While rates of uterine rupture vary significantly according to a variety of clinically associated risk factors, the absolute risk for this complication ranges between 0.5 and 4 percent. Previous vaginal delivery and prior successful vaginal birth after cesarean delivery conf...
