Lutembacher syndrome is characterized by a congenital ostium secundum atrial septal defect and an acquired mitral valve stenosis. We present a similar case in a 31-year old male who came in with orthopnoea, central cyanosis and pedal oedema. Examination revealed cardiac murmurs in tricuspid and apical regions. Chest x-ray showed signs of pulmonary congestion and ventricular enlargement. Electrocardiogaphy (ECG) revealed right axis deviation and right bundle branch block along with atrial fibrillation and Transthoracic Echocardiography (TTE) showed abnormal valves (mitral stenosis with calcification and tricuspid regurgitation) and dilated cardiac chambers...

To address controversy surrounding the most appropriate comparison group for mild traumatic brain injury (mTBI) research, mTBI patients aged 12-30 years were compared to an extracranial orthopedic injury (OI) patient group and an uninjured, typically-developing (TD) participant group with comparable demographic backgrounds. Injured participants underwent subacute (within 96 hours) and late (3 months) diffusion tensor imaging (DTI); TD controls underwent DTI once. Group differences in fractional anisotropy (FA) and mean diffusivity (MD) of commonly studied white matter tracts were assessed...

Traumatic axonal injury (TAI) contributes significantly to mortality and morbidity after traumatic brain injury (TBI) but its identification is still a diagnostic challenge because of the limitations of conventional imaging techniques to characterized it. Diffusion tensor imaging (DTI) can indirectly identify areas of damaged white matter (WM) integrity by detecting water molecules diffusion alterations. Therefore, DTI may improve detection and description of TAI lesions after TBI. We have obtained DTI data from 217 patients with moderate to severe TBI acquired at median 19 days after TBI were and patient DTI metrics were compared with data obtained from 58 age-matched healthy controls...

Background: Previous Diffusion Tensor Imaging (DTI) studies have demonstrated the temporal evolution of stroke injury in grey matter and white matter can be characterized by DTI indices. However, it still remains not fully understood how the DTI indices of white matter are altered progressively during the hyperacute (first 6 hours) and acute stage of stroke (≤ 1 week). In the present study, DTI was employed to characterize the temporal evolution of infarction and white matter injury after stroke insult using a macaque model with permanent ischemic occlusion...

The organization and number of microtubules (MTs) in a cell depend on the proper regulation of MT nucleation. Currently, the mechanism of nucleation is the most poorly understood aspect of MT dynamics. XMAP215/chTOG/Alp14/Stu2 proteins are MT polymerases that stimulate MT polymerization at MT plus ends by binding and releasing tubulin dimers. Although these proteins also localize to MT organizing centers and have nucleating activity in vitro, it is not yet clear whether these proteins participate in MT nucleation in vivo...

Innovative methods to ensure better compliance in hand hygiene are urgently needed. The aim of this study was to determine if WiFi-based hand hygiene dispenser-driven self-assessment systems (Wireless Fidelity, WiFi-dispenser) can support the work of infection control teams. Our results suggest that the continuous monitoring of dispenser usage can be a valuable addition to infection prevention and control programs, when used in a bundle in combination with conventional hand hygiene training.

Although the basolateral amygdala (BLA) and serotonin6 (5-HT6 ) receptor are involved in modulation of anxiety, their roles in Parkinson' disease (PD)-related anxiety are still unknown. Thus we perform this study to examine the involvement of BLA 5-HT6 receptor on anxiety in unilateral 6-hydroxydopamine-induced PD rats. The lesion of the medial forebrain bundle (MFB) induced anxiety-like behaviors, and decreased the basal firing rate of BLA glutamate neurons and dopamine (DA) levels in tissues of the medial prefrontal cortex (mPFC), amygdala and ventral part of hippocampus (vHip) in rats...

The host actin cytoskeleton is utilized by an assortment of pathogenic bacteria to colonize and cause disease in their hosts. Two prominently studied actin-hijacking bacteria are enteropathogenic Escherichia coli (EPEC) and Listeria monocytogenes. EPEC form actin-rich pedestals atop its host cells to move across the intestinal epithelia, while Listeria monocytogenes generate branched actin networks arranged as actin clouds around the bacteria and as comet tails for propulsion within and amongst their host cells...
