single coil from a stress perfusion exam is considered. Few spatial frames and the image time profile are shown for the temporal TV constrained reconstruction (first row), and the proposed method (second row). The TV reconstruction had temporal blurring especially evident in frames with high motion (see arrows in top row). In contrast, the proposed scheme had crisper images with better temporal...

Background: Our aim was to investigate the motor outcome, effects on the diaphragm muscle, and delimit the regained nerve conduction capacity of the transected phrenic nerve, following its reconstruction to prepare the subjects to electrophrenic respiration. Methods: All one-year-old 12 healthy pigs (German Landrace) weighing 45 to 50 kg were used in the study. Three groups, each of which consi...

Tomographic reconstruction from PET data is an ill-posed problem that requires regularization. Recently, Daubechies et al. [1] proposed an l (1) regularization of the wavelet coefficients that can be optimized using iterative thresholding schemes. In this paper, we extend this approach for the reconstruction of dynamic (spatio-temporal) PET data. Instead of using classical wavelets in the tempo...

Prevention of the atrophy of denervated muscles is essential for a good outcome in facial contouring and oral reconstruction. In this study, we compared the effectiveness of end-to-end and end-to-side neurorrhaphy of the motor nerve, and end-to-end neurorrhaphy of the sensory nerve, all of which are frequently used in such reconstruction for the prevention of muscle atrophy. Wistar rats were di...

UNLABELLED BACKGROUND The aim was to evaluate what can be learned from rat models when treating patients suffering from a sciatic nerve injury. METHODS Two patients with traumatic sciatic nerve injury are presented with examination of motor and sensory function with a five-year follow-up. Reconstruction of the nerve injury was performed on the second and third day, respectively, after inju...

BACKGROUND Unilateral phrenic nerve injury often results in symptomatic hemidiaphragm paralysis, and currently few treatment options exist. Reported etiologies include cardiac surgery, neck surgery, chiropractic manipulation, and interscalene nerve blocks. Although diaphragmatic plication has been an option for treatment, the ideal treatment would be restoration of function to the paralyzed hem...

Electrical impedance tomography (EIT) provides low-resolution images of internal conductivity distributions, but is able to achieve relatively high temporal resolutions. Most EIT image reconstruction algorithms do not explicitly account for the temporal constraints on the measurements or physiological processes under investigation. Instead, algorithms typically assume both that the conductivity...

BACKGROUND The purpose of this article is to evaluate a new method of DIEP flap neurotization using a reliably located recipient nerve. We hypothesize that neurotization by this method (with either nerve conduit or direct nerve coaptation) will have a positive effect on sensory recovery. METHODS Fifty-seven deep inferior epigastric perforator (DIEP) flaps were performed on 35 patients. Neurot...

OBJECTIVE To define the relationship between the frontal branch of the facial nerve and a series of blood vessels that are encountered during endoscopic forehead procedures. DESIGN Anatomical study using 6 fresh cadavers (12 sides). RESULTS In 11 of 12 dissected specimens, the blood vessels in the temporal region were found to lie within 2 mm of the frontal branch of the facial nerve. CON...

The human brain is a complex system consist of connected nerve cells that adapts with and learn from the environment by changing its regional activities. Synchrony between these regional activities called functional network changes during the life, and with learning of new skills. Time perception and interval discrimination are among the most necessary skills for the human being to perceive mot...
