  1. The role of cholecystokinin in the induction of aggressive behavior: a focus on the available experimental data (review)

    Katsouni, E.; Zarros, Apostolos; Skandali, N.; Tsakiris, Stylianos; Lappas, D.
    Cholecystokinin (CCK) is a neuropeptide that is (among others) reportedly involved in the pathophysiology of psychiatric disorders. The excitatory role of CCK in negative affective emotions as well as in aversive reactions, antisocial behaviors and memories, has been indicated by numerous electrophysiological, neurochemical and behavioral methodologies on both animal models for anxiety and human studies. The current review article summarizes the existing experimental evidence with regards to the role of CCK in the induction of aggressive behavior, and: (a) synopsizes the anatomical circuits through which it could potentially mediate all types of aggressive behavior, as well as (b) highlights the...

  5. Anatomy Apps

    Durnin, Lisa; Rea, Paul
    Anatomy has a rich and florid history through time. Traditional teaching has focused on the use of cadavers, but now we have moved into the ‘digital era’, technologies are being increasingly adopted in anatomical teaching. One popular approach is mobile learning (M-learning) which includes the use of applications (apps). Apps are widely available across a number of platforms, allowing immediate access to updated anatomical information. However, there is a lack of comparative studies examining the content available. Therefore, this study examined 20 popular anatomy apps across iOS and Windows platforms to determine if any could be recommended for use in...

  6. Platysma as a Candidate for Facial Reanimation

    Solomou, Anastasia; Durnin, Lisa; Rea, Paul
    Facial reanimation around the orbit remains a challenge in plastic surgery. Platysma has been shown to be an ideal muscle for transfer as it is structurally similar to orbicularis oculi. The aim of this study was to investigate the neurovasculature of the platysma muscle to identify if there was a common site for the neurovasculature stem to be identified at for transfer. Platysma was dissected in two male formaldehyde fixed cadavers (84 and 88 years old) with no craniofacial abnormalities, in accordance with relevant legislation. To confirm structures identified at dissection, we performed histological analysis of all structures. We have shown that...

  7. Monoaxial external fixation of the calcaneus: an anatomical study assessing the safety of monoaxial pin insertion

    Thomson, Callum M.; Esparon, Tom; Rea, Paul M.; Jamal, Bilal
    The use of external fixation for intra-articular calcaneal fractures is increasing in popularity. Studies have shown fine wire and monoaxial external fixation to be a viable surgical alternative to more invasive methods of open reduction and internal fixation of the calcaneus. However, there is an absence of literature that quantifies the risk of pin insertion for monoaxial fixation. This study aimed to determine the safety of inserting monoaxial pins within the calcaneus to house the Orthofix Calcaneal Mini-Fixator. Five formalin embalmed cadaveric ankle and lower leg specimens were inserted with six monoaxial pins. Careful dissection then revealed the presence of the...

  8. Essential Clinically Applied Anatomy of the Peripheral Nervous System in the Limbs

    Rea, Paul
    Essential Clinically Applied Anatomy of the Peripheral Nervous System in the Limbs is designed to combine the salient points of the anatomy of the PNS with typical pathologies affecting the nerves of the upper and lower limbs. The peripheral nervous system is the division of the nervous system containing all the nerves that lie outside of the central nervous system. This book is a quick reference guide for those studying and treating neuromuscular disease such as neurologists, neurosurgeons, neuroradiologists, as well as for clinical neurophysiologists. The reader will be presented with easy-to-access facts about the anatomy of the nerves in...

  9. A novel method of anatomical data acquisition using the Perception ScanWorks V5 scanner

    Welsh, Elizabeth; Anderson, Paul; Rea, Paul
    A drastic reduction in the time available for cadaveric dissection and anatomy teaching in medical and surgical education has increased the requirement to supplement learning with the use of virtual gross anatomy training tools. In light of this, a number of known studies have approached the task of sourcing anatomical data from cadaveric material for end us in creating 3D reconstructions of the human body by producing vast image libraries of anatomical cross sections. However, the processing involved in the conversion of cross sectional images to reconstructions in 3D elicits a number of problems in creating an accurate and adequately...

  10. A multimedia package for patient understanding and rehabilitation of non-contact anterior cruciate ligament injuries

    Buchanan, Gordon; Minhua, Ma; Rea, Paul M.
    Non-contact anterior cruciate ligament (ACL) injury is one of the most common ligament injuries in the body. Many patients’ receive graft surgery to repair the damage, but have to undertake an extensive period of rehabilitation. However, non-compliance and lack of understanding of the injury, healing process and rehabilitation means patient’s return to activities before effective structural integrity of the graft has been reached. When clinicians educate the patient, to encourage compliance with treatment and rehabilitation, the only tools that are currently widely in use are static plastic models, line diagrams and pamphlets. As modern technology grows in use in anatomical...

  11. Investigating human audio-visual object perception with a combination of hypothesis-generating and hypothesis-testing fMRI analysis tools

    Naumer, M.J.; van den Bosch, J.; Wibral, M.; Kohler, A.; Singer, W.; Kaiser, J.; van de Ven, V.; Muckli, L.
    Primate multisensory object perception involves distributed brain regions. To investigate the network character of these regions of the human brain, we applied data-driven group spatial independent component analysis (ICA) to a functional magnetic resonance imaging (fMRI) data set acquired during a passive audio-visual (AV) experiment with common object stimuli. We labeled three group-level independent component (IC) maps as auditory (A), visual (V), and AV, based on their spatial layouts and activation time courses. The overlap between these IC maps served as definition of a distributed network of multisensory candidate regions including superior temporal, ventral occipito-temporal, posterior parietal and prefrontal regions....

  12. Preconditioning with 4-aminopyridine protects cerebellar granule neurons against excitotoxicity

    Smith, A.; Tauskela, J.S.; Stone, T.W.; Smith, R.A.
    Preconditioning by excitatory stimuli such as N-methyl-D-aspartate (NMDA) offers good neuroprotection against excitotoxic insults, but is potentially limited by the risk of damage associated with the treatment. We report here on the potential of an alternative strategy, tested on rat neonatal cerebellar granule neurons, which involves a 48-hour preconditioning step using the potassium channel blocker 4-aminopyridine (4-AP), at a low (50 µM) and at a higher (2500 µM) concentration (in the presence or absence of the GABAA receptor antagonist, bicuculline). 4-Aminopyridine gave extensive protection against a number of stressors (glutamate, NMDA and 3-nitropropionic acid) applied 24 hours following the end...

  13. FES cycling with electric motor assist

    Hunt, K.J.; Stone, B.; Negaard, N.-O.; Schauer, T.; Fraser, M.H.
    The aim of this study was to develop and test feedback control strategies for integration of elec- tric motor assist and functional electrical stimula- tion for paraplegic cycling. An integrated two-loop feedback control strategy is proposed, in which the electric motor is driven to provide feedback con- trol of cycling speed, and the cyclist's leg power is controlled by automatic variation of stimulation intensity. Representative experimental results are presented for one complete-lesion paraplegic sub- ject. The results show accurate feedback control of: cycle cadence; leg power; and external distur- bance rejection. We conclude that the addition of electric motor assist, with an integrated feedback control strategy, can compensate for external dis- turbances, it can greatly...

  15. The study of skeletal calcium metabolism with Ca-41 and Ca-45

    Freeman, S.P.H.T.; Beck, B.; Bierman, J.M.; Caffee, M.W.; Heaney, R.P.; Holloway, L.; Marcus, R.; Southon, J.R.; Vogel, J.S.
    The living skeleton can be labeled for life by the administration of radiologically trivial amounts of Ca-41 tracer. After initial elimination of tracer from the readily exchangeable calcium pools subsequent skeletal calcium turnover maintains and modulates the urine Ca-41 content. Uniquely, bone calcium metabolism may then be studied with tracer in near equilibrium with the body's calcium and resorbing calcium directly measured by accelerator mass spectrometry (AMS) of excreta. Our experiments with 25 Ca-41 labeled subjects demonstrate excellent diurnal stability and remarkable response to intervention of the urine signal. Thus the tracer method may prove a competitive means of measuring...
