Non-ischemic rupture of the posteromedial papillary muscle due to endocarditis.

Unlabelled: Papillary muscle rupture is usually caused by myocardial infarction although rare cases of non-ischemic etiology have also been described. Among these, infective endocarditis represents an important cause. Herein, we report a case due to involving the posteromedial papillary muscle.

Do False Tendons Prevent Adverse Left Ventricular Remodeling After Anterior Wall Myocardial Infarction? An Echocardiographic Strain Imaging Study.

The role of muscular left ventricular (LV) false tendons (FTs) is poorly understood. To gain insight into their pathophysiologic significance, we adapted echocardiographic LV strain imaging software to measure LVFT longitudinal strain in subjects with normal left ventricles and in patients who sustained previous anterior wall myocardial infarction (AWMI). GE EchoPAC software was used to measure longitudinal strain in LVFTs ≥0.

Novel KIF7 missense substitutions in two patients presenting with multiple malformations and features of acrocallosal syndrome.

We present two children who both had two missense mutations in the Kinesin Family Member 7 (KIF7) gene. A seven year old female with severe developmental delays, failure to thrive and growth retardation, infantile spasms, a cardiac vascular ring and right-sided aortic arch, imperforate anus, hydronephrosis with a right renal cyst, syndactyly and abnormal white matter was a compound heterozygote for c.3365C > G, predicting p.

De novo ANKRD11 and KDM1A gene mutations in a male with features of KBG syndrome and Kabuki syndrome.

KBG syndrome is a rare, autosomal dominant disorder caused by mutations or deletions leading to haploinsufficiency for the Ankrin Repeating Domain-Containing protein 11 (ANKRD11) at chromosome 16q24.3. Kabuki syndrome is caused by mutations or deletions of lysine (K)-specific methyltransferase 2D (KMT2D) and lysine-specific methylase 6A (KDM6A).

A physiological signal that prevents motor skill improvements during consolidation.

Different memories follow different processing pathways. For example, some motor skill memories are enhanced over wakefulness, whereas others are instead enhanced over sleep. The processing pathway that a motor skill memory follows may be determined by functional changes within motor circuits.
