case presentation our patient was a 32-year-old primigravid woman presented with abdominal and flank pain. her gestational age was 30 weeks. during admission in aria hospital, she had a significant hemoglobin level drop and developed signs of acute abdomen. conclusions laparotomy was performed and fundal uterine vessels rupture was seen and ligated. a 30-week-male fetus was born by cesarean sec...

background: uterine rupture in pregnancy is rare and often could be life threatening and catastrophic. myomectomy is one of very common surgeries in gynecology, performed as the vaginal, abdominal and laparoscopic surgeries. pregnancies occured after abdominal and laparoscopic myomectomy are high risk for uterine rapture. case: patient was a 28 years old female, pregnant woman at the 20 wks of ...

a 74-year-old male patient was admitted to our emergency department with post-mi angina. on account of the anginal complaint that continued for three days, a coronary artery angiography was undertaken. a percutaneous transluminal coronary angioplasty was performed, followed by the implantation of a coronary stent, and coronary perfusion (timi-3) was achieved in the left anterior descending arte...

pneumatic rectosigmoid rapture is usually occurred following the inappropriate fun by direct entering a high volume of the air through the pneumatic device to the anus. such an event was reported for the first time in 1904 by stone. diagnosis and treatment of such injuries are often delayed because of some social limitations and preventing the patient form explaining the event. colon sigmoid ru...

The fundamental fracture mechanisms of biological protein materials remain largely unknown, in part, because of a lack of understanding of how individual protein building blocks respond to mechanical load. For instance, it remains controversial whether the free energy landscape of the unfolding behavior of proteins consists of multiple, discrete transition states or the location of the transiti...

We compared two methods of delivering single damped sine-wave defibrillator pulses to the coronary sinus orifice in 20 dogs. Ten dogs had "unipolar" (coronary sinus to precordial disc) and 10 had "bipolar" (coronary sinus proximal to coronary sinus distal electrode) discharges. Delivered voltage, current, and energy were recorded during each pulse. Electrophysiologic testing was done before and...

This paper presents a physically based theory to model the strength and lifetime distributions of quasibrittle structures. The theory is derived from the fracture mechanics of atomic lattice cracks propagating through the lattice by tiny jumps over numerous activation energy barriers on the surface of the free energy potential of the lattice, caused by crack length jumps by one atomic spacing. ...

[1] Compressive sensing (CS) is a technique for finding sparse signal representations to underdetermined linear measurement equations. We use CS to locate seismic sources during the rupture of the 2011 Tohoku‐Oki Mw9.0 earthquake in Japan from teleseismic P waves recorded by an array of stations in the United States. The seismic sources are located by minimizing the ‘2‐norm of the difference be...

In enhanced oil recovery (EOR), the micro-oil droplet heavily affected the stability of foam and prevented foam flooding. In this paper, the oil bridge-stretching mechanism of foam rupture was described through molecular dynamics with the aim of providing supplements to the experiments at the molecular level. Two important phenomena for foam rupture have been pointed out by the simulation. One ...
