BACKGROUND Phase sensitive inversion recovery (PSIR) applied to late gadolinium enhancement (LGE) imaging is widely used in clinical practice. However, conventional 2D PSIR LGE sequences provide sub-optimal contrast between scar tissue and blood pool, rendering the detection of subendocardial infarcts and scar segmentation challenging. Furthermore, the acquisition of a low flip angle reference ...

We characterized prime-boost vaccine regimens using heterologous and homologous vector and gene inserts. Heterologous regimens offer a promising approach that focuses the cell-mediated immune response on the insert and away from vector-dominated responses. Ad35-GRIN/ENV (Ad35-GE) vaccine is comprised of two vectors containing sequences from HIV-1 subtype A gag, rt, int, nef (Ad35-GRIN) and env ...

conclusions glenohumeral joint reduction with reconstruction of the humeral head seems to be possible even in a neglected locked posterior shoulder fracture-dislocation. if the depressed osteochondral fragment is still spheric, signs of the avascular necrosis are absent on ct, and mal:union: of the fragment has occurred, it is quite possible to reconstruct the head. although results of the case...

objective: the abdominal sacrocolpopexy is the standard method of vaginal prolapse correction and posterior intravaginal slingplasty (pivs) is a newer procedure with minimal invasiveness. this study compares the effectiveness and complications of these two surgical methods. materials and methods: in this non randomized clinical trial study, which was conducted in imam khomeini hospital, tehran,...

introduction: based on the invasive studies it has been shown that factors such as age, the progress of eye disorders, lens fibers compression and the biochemical changes of ocular matrix alter the physical characteristics and elastic properties of eye. in this study, a noninvasive method of estimating human eye elasticityis proposed and its relation with age and gender is evaluated using ultra...

absractall perilunate fracture-dislocations combine bone avulsions, ligament disruptionand fractures in different forms. the most frequent pattern is the dorsal transscaphoidperilunate fracture-dislocation. the reported risk of missed initial diagnosisin perilunate dislocations is as high as 20%. concerning pathomechanics of theperilunate fracture-dislocation, it should be noted that most dorsa...

A Power Factor Correction Using singleinductor dual-output buck-boost converter operating in critical conduction mode is proposed in this paper. Each output of the SingleInductor Dual-Output buck-boost converter can be regulated independently by multiplexing a single inductor, Compared with a conventional two-stage multiple-output converter, the singleinductor dual-output buck-boost converter b...

New emerging viruses like coronavirus 2019 (COVID-19) infections are always frightening. We know little about theirtransmission, behaviors, clinical manifestations, and outcomes. There is no vaccine or therapeutic strategies to dealwith these infections yet. In this situation, preventive measures may be promising. Hand hygiene is a very importantissue in preventing viral infec...

Hadamard multiplexing provides a considerable SNR boost over additive random noise but Poisson noise such as photon noise reduces the boost. We develop the theory for full H-matrix Hadamard transform imaging under additive and Poisson noise effects. We show that H-matrix encoding results in no effect on average on the noise level due to Poisson noise sources while preferentially reducing additi...

Preferred chroma enhancement and its dependence on hue are studied in a twopart experiment using a wide-gamut multi-primary display. Earlier research showed a clear dependence on hue but was limited by the gamut of the display it employed; the present work builds on this while removing the gamut constraints. In the first part of the present experiment, a tuning task was used to refine the prefe...
