Intramyocardial dissecting hematoma is an infrequent complication of subacute myocardial infarction. Pathological findings consist of a cavity filled with blood, the outer wall of which is the myocardium and pericardium and the inner wall, which faces the ventricular cavity, is part of the myocardium and endocardium. There is scarce information on the subject and the management of these patient...

ultiple calcifying hyperplastic dental follicles (MCHDF) are disorders characterized by multiple unerupted teeth with abundant calcifications and rests of odontogenic epithelium in enlarged dental follicles. Recently, I encountered a case of MCHDF and while reviewing the scientific literature, I came across a similar case report published by Jamshidi et al, published in the Journal of Dental Re...

The spindle assembly checkpoint (SAC) arrests mitosis until bipolar attachment of spindle microtubules to all chromosomes is accomplished. However, when spindle formation is prevented and the SAC cannot be satisfied, mammalian cells can eventually overcome the mitotic arrest while the checkpoint is still activated. We find that Aspergillus nidulans cells, which are unable to satisfy the SAC, in...

Spatial autocorrelation (SAC) is the dependence of a given variable’s values on the values of the same variable recorded at neighboring locations (Cliff and Ord 1973; Fortin and Dale 2005). When high values are associated with relatively high values at neighboring locations, SAC is said to be positive and, conversely, where high values correspond to relatively low values at neighboring location...

Background: Outbreak of bluetongue virus serotype-8 (BTV-8) infection in domestic ruminants in Northern Europe. Objective: To investigate the South American camelids’ (SAC) susceptibility to BTV-8 infection, their role in the epidemiology of the disease, and the use of currently available serological screening tests in SAC in an endemic region. Animals: Three hundred and fifty-four unvaccinated...

The female gametophyte of flowering plants, the embryo sac, develops within the diploid (sporophytic) tissue of the ovule. While embryo sac-expressed genes are known to be required at multiple stages of the fertilization process, the set of embryo sac-expressed genes has remained poorly defined. In particular, the set of genes responsible for mediating intracellular communication between the em...

CONGENITAL pericardial defect is a rare anomaly, which was first described by M. Columbus in 1559.1 2 Four hundred years later the first clinical diagnosis was reported by Ellis et al.2 In 1961, 108 cases were compiled from the literature and since then we have located reports of five more.3-6 Chang and Leigh' reported that 67 per cent of t-he defects were left sided, and in three instances bil...

In recurrent or persistent pericardial effusion a subxiphoid pericardial window may be used to drain fluid from the pericardial cavity.' 3 A more permanent form of drainage may be achieved if a combined peritoneal pericardial window is used.4 We describe a case in which we could not initially reach the pericardial effusion through a pericardial window because it was loculated posteriorly. Subse...

We describe a case of an abdominal pregnancy which presented in the first trimester with rapid accumulation of blood stained ascites. The ascites resolved completely following surgical removal of a gestational sac from the peritoneal cavity. The pathophysiology of ascites in this case may be similar to that in cases of ascites in other non-malignant gynaecological conditions.

Neighbourhood singleton arc consistency (NSAC) is a type of singleton arc consistency (SAC) in which the subproblem formed by variables adjacent to a variable with a singleton domain is made arc consistent. This paper describes two extensions to neighbourhood SAC. The first is a generalization from NSAC to k-NSAC, where k is the maximum length of the shortest path between the singleton variable...
