Recent fMRI evidence shows differential involvement of the inferior frontal gyrus (IFG) and the ventral premotor cortex (PMv) in syntactic processing. Our main goal is to specify the precise role of the PMv in the processing sequential structures and whether these processes are a necessary prerequisite for the successful acquisition of linguistic syntax. We tested patients with PMv lesions in a...

Parachute Mitral Valve (PMV) is a rare congenital cardiac defect characterized by focalized attachment of the chordae tendinae of both leaflets to a single papillary muscle [1]. It may occur as an isolated lesion or part of a Shone’s anomaly in infants and young children [2]. Not much is known about PMV in adults [3]. There have been reports of complete Atrioventricular Septal Defects (AVSD) as...

Previously, we showed that the ventral premotor cortex (PMv) underwent neurophysiological remodeling after injury to the primary motor cortex (M1). In the present study, we examined cortical connections of PMv after such lesions. The neuroanatomical tract tracer biotinylated dextran amine was injected into the PMv hand area at least 5 months after ischemic injury to the M1 hand area. Comparison...

BACKGROUND An increasing number of patients require prolonged mechanical ventilation (PMV), which is associated with high morbidity and poor long-term survival, but there are few data regarding the incidence and outcome of PMV patients from a community perspective. METHODS We retrospectively reviewed the electronic medical records of adult Olmsted county, Minnesota, residents admitted to the...

Replanning ongoing movements following perturbations requires the accurate and immediate estimation of the motor response based on sensory input. Previous studies have used transcranial magnetic stimulation (TMS) in humans to demonstrate the participation of the anterior intraparietal sulcus (aIPS) and ventral premotor cortex (PMv) in visually mediated state estimation for grasping. Here, we te...

In contrast to other retroviruses, Mason-Pfizer monkey virus (M-PMV) assembles immature capsids in the cytoplasm. We have compared the ability of minimal assembly-competent domains from M-PMV and human immunodeficiency virus type 1 (HIV-1) to assemble in vitro into virus-like particles in the presence and absence of nucleic acids. A fusion protein comprised of the capsid and nucleocapsid domain...

Situs inversus totalis is a rare congenital disorder where the heart being a mirror image is situated on the right side of the body. Distorted cardiac anatomy makes fluoroscopy-guided percutaneous mitral valvotomy (PMV) technically challenging and there are only few reports of PMV in situs inversus totalis. Here we report a case where PMV was successfully done for situs inversus totalis with ra...

INTRODUCTION Due to the importance of prolonged mechanical ventilation (PMV) as a postoperative complication, predicting "high-risk" patients by identifying predisposing risk factors is of important issue. The present study was aimed to identify perioperative variables associated with PMV in patients undergoing open heart surgery. METHODS A total of 743 consecutive patients, American Society ...

OBJECTIVES The purpose of the present study was to compare the long-term clinical and echocardiographic results of the Inoue and the double-balloon techniques. BACKGROUND The large randomized trial comparing the extent of commissurotomy and the long-term results between the double-balloon and Inoue balloon techniques has not been reported. METHODS We conducted a prospective, randomized tria...

Classically, it has been hypothesized that reach-to-grasp movements arise from two discrete parietofrontal cortical networks. As part of these networks, the dorsal premotor cortex (PMd) has been implicated in the control of reaching movements of the arm, whereas the ventral premotor cortex (PMv) has been associated with the control of grasping movements of the hand. Recent studies have shown th...
