A coexisting anatomic variation of median and ulnar nerves in a cadaver palm

During a routine dissection we observed an anatomical variation of the median nerve and an atypical anastomosis in the palm region of a male cadaver. There were four distinct recurrent motor branches of the left median nerve and the palmar cutaneous branch of the ulnar nerve communicated directly with the third common palmar digital nerve. The presence of such anatomical variant in the hand should keep surgeons alert in the management of hand pathology especially in carpal tunnel syndrome which is a routine operation for many medical centers

Χρήση του δείκτη QBR για την εκτίμηση των επιπτώσεων της κατασκευής φραγμάτων κατά μήκος της κοίτης ενός μεσογειακού χειμάρρου στην παρόχθια βλάστηση

Ο χείμαρρος «Γεραμπίνη» Ζαγοράς Πηλίου, ο οποίος αποτελεί την περιοχή μελέτης, είναι ένα υδατικό οικοσύστημα με έντονες διακυμάνσεις στο υδρολογικό του ισοζύγιο. Με κύριο στόχο την αποτροπή των πλημυρρικών φαινομένων, κατασκευάστηκαν κατά μήκος του, είκοσι ένα (21) φράγματα στερέωσης. Στην παρούσα εργασία προσδιορίζεται και αναλύεται ο δείκτης QBR «Qualitat del Bosc de Ribera», ο οποίος αποτελεί έναν αξιόπιστο ποιοτικό δείκτη της παρόχθιας βλάστησης για τα μεσογειακά υδατικά οικοσυστήματα. Από την συλλογή, επεξεργασία και ανάλυση των δεδομένων προκύπτει ότι η τεχνητή διευθέτηση του μεσογειακού χειμάρρου δεν αποτέλεσε τροχοπέδη στη διατήρηση και στην αναβάθμιση της δυναμικής των στοιχείων που συντελούν στη φυσική εξέλιξη της παρόχθιας βλάστησής του

Probing the Space of Toric Quiver Theories

We demonstrate a practical and efficient method for generating toric Calabi-Yau quiver theories, applicable to both D3 and M2 brane world-volume physics. A new analytic method is presented at low order parametres and an algorithm for the general case is developed which has polynomial complexity in the number of edges in the quiver. Using this algorithm, carefully implemented, we classify the quiver diagram and assign possible superpotentials for various small values of the number of edges and nodes. We examine some preliminary statistics on this space of toric quiver theories

Tract-Based Spatial Statistics Analysis of Diffusion-Tensor Imaging Data in Patients with Small Cell Lung Cancer.

Prophylactic cranial irradiation (PCI) is known to improve survival to a significant degree in Small Cell Lung Cancer (SCLC) patients. The aim of our study is to investigate changes in structural connectivity between healthy-volunteers and patients with SCLC, before and after PCI treatment. In this preliminary study we use diffusion tensor imaging (DTI) to identify changes in white matter structure in patient group pre radiotherapy to control group. The results have showed alterations in white matter structure. In the patient group lower fractional anisotropy (FA) and higher eigenvalues in white matter regions are observed compared to the control group. The results presented herein are subject to further investigation with larger patient and control groups

Analysis of resting state and task-related fMRI data in small cell lung cancer patients before undertaking PCI

As the use of prophylactic cranial irradiation (PCI) increases life expectancy in certain types of cancer, there is evidence that this technique may contribute to neurocognitive deficits. The aim of this research is to investigate functional connectivity in patients before and after being administered brain radiotherapy as well as their neurocognitive functionality, depending on the course of disease and the phase of treatment and time of clinical examination. In the current study we attempt to identify potential alterations in brain function during resting state and task-related functional magnetic resonance imaging (fMRI) in small cell lung cancer patients (SCLC) patients before PCI compared to healthy subjects. The brain regions that were activated for both groups during a sequential tapping task are consistent with previous studies. However, the patient group showed a lower level of activation in the primary somatosensory cortex bilaterally. During rest, the Default Mode Network (DMN) was identified in both groups. The results presented are subject to further investigation with larger patient and control group
