atrioventricular groove rupture is a rare, albeit mortal, complication following mitral valve surgery. avoidance is the best strategy but it cannot fully prevent the occurrence of this complication. several repair techniques have been described with varying success rates; however, the rarity of the complication precludes consensus about the safest technique. here we report two cases of posterio...

introduction left ventricular free wall rupture (lvfwr) is a frequent cause of death after acute myocardial infarction, and its repair remains a surgical challenge. conclusions a hemodynamic study was acceptable at a 12-month follow-up, and no complication was seen. case presentation tachosil® is a ready-to-use equine collagen patch which has been successfully used for hemostasis in cardiovascu...

left ventricular free wall rupture is responsible for up to 10% of in-hospital deaths following myocardial infarction. it is mainly associated with posterolateral myocardial infarction, and its antemortem diagnosis is rarely made. one of the medical complications of myocardial infarction is the rupture of the free wall, which occurs more frequently in the anterolateral wall in hypertensives, wo...

this study was carried out to determine the effect of seed growing regions and loading speed on some mechanical properties of castor seed. these properties are used to design and improve related machines such as expeller that are used for extraction of oil from castor seed. mechanical properties of castor seed were expressed in terms of rupture force and energy, bio-yield force, apparent modulu...

dried figs collected from various exporting companies (2,461 samples) and local stores (219 samples) were analyzed using reverse-phase high-performance liquid chromatography (rp-hplc) to determine and compare the incidence of aflatoxins, the effectiveness of the regulation limits and monitoring system to select non-compliant samples and the mean daily aflatoxin exposures. the incidence rates of...

safflower is a strategic plant regarding to its valuable nutrition value (45% extractable oil) and industrial uses. due to massive import of edible oil to the country as well as high potential for safflower cultivation, the research on production of safflower for oil extrusion purpose is of remarkable importance. the design of various processing and oil extraction units and also their optimizat...
