Comparing the Distribution of Strains with the Distribution of Bone Tissue in a Human Mandible: A Finite Element Study
Abstract Comparative anatomy and experimental studies suggest that the mass and distribution of tissue within a bone is adapted to the strains the bone experiences during function. Finite element analysis is a powerful tool that can be used to investigate this since it allows the creation of hypothetical models with unadapted morphology. Here we use FE models of a human mandible with modified internal morphology to study the relationships between the gross distribution of bone tissue (i.e., the presence or absence of bone in a certain area), the variation of cortical bone thickness within the mandible and the distribution ...

Right Ventricular Outflow Tract Imaging With CT and MRI: Part 1, Morphology
CONCLUSION. A spectrum of conotruncal anomalies with abnormally positioned great arteries may arise from a perturbation of RVOT formation. Complications after surgery are common, and many patients need follow-up imaging for diagnosis and surgical planning. In this regard, the spectrum of diseases, differential diagnoses, and postoperative findings are briefly described. With CT and MRI, the relationship of the RVOT to critical structures, such as the coronary arteries, can be revealed.

dcGO: database of domain-centric ontologies on functions, phenotypes, diseases and more
We present ‘dcGO’ (http://supfam.org/SUPERFAMILY/dcGO), a comprehensive ontology database for protein domains. Domains are often the functional units of proteins, thus instead of associating ontological terms only with full-length proteins, it sometimes makes more sense to associate terms with individual domains. Domain-centric GO, ‘dcGO’, provides associations between ontological terms and protein domains at the superfamily and family levels. Some functional units consist of more than one domain acting together or acting at an interface between domains; therefore, ontological terms associated with ...

Beyond the arcuate fasciculus: consensus and controversy in the connectional anatomy of language
The growing consensus that language is distributed into large-scale cortical and subcortical networks has brought with it an increasing focus on the connectional anatomy of language, or how particular fibre pathways connect regions within the language network. Understanding connectivity of the language network could provide critical insights into function, but recent investigations using a variety of methodologies in both humans and non-human primates have provided conflicting accounts of pathways central to language. Some of the pathways classically considered language pathways, such as the arcuate fasciculus, are now arg...

Diagnosis of Renal Disease in Rabbits
There are differences in renal anatomy and physiology between rabbits and other domestic species. Neurogenic renal ischemia occurs readily. Reversible prerenal azotemia may be seen in conjunction with gut stasis. Potentially fatal acute renal failure may be due to structural kidney damage or post-renal disease. Chronic renal failure is often associated with encephalitozoonosis. Affected rabbits cannot vomit and often eat well. Weight loss, lethargy, and cachexia are common clinical signs. Polydypsia/polyuria may be present. Derangements in calcium and phosphorus metabolism are features of renal disease. Radiography is alwa...

Primary and revision THA using a stemless metaphyseal-loading implant above distorted proximal femoral anatomy.
We present seven patients with distorted proximal femoral anatomy or failed hip arthroplasty in whom a short, metaphyseal loading implant was utilised. At minimum two-year follow-up there have been no complications with all stems stable and well fixed radiologically. Average improvement in Oxford Hip Score is 32. We suggest that a short, metaphyseal loading prosthesis can be considered in cases where a conventional stemmed implant may not be suitable due to challenging proximal femoral anatomy.

Evaluation of anatomy, variation and anomaly of the coronary arteries with coronary computed tomography angiography.
Abstract Recent technical advances in computed tomography (CT) have improved image quality, diagnostic performance and accuracy of coronary CT angiography (CCTA). Latest dose-reduction strategies reduce radiation dose to an acceptable level even lower than that from conventional coronary angiography. CCTA is a noninvasive imaging modality which can effectively show complex coronary artery anatomy, variations and congenital anomalies of the coronary arteries. Congenital coronary artery anomalies are rare entities, but sometimes have a potential of producing fatal consequences. CCTA is now the primary imaging modalit...

Prevalence of sesamoid bones in the interphalangeal joint of the thumb and fingers: A radiographic study
Abstract The prevalence of sesamoid bones in the hands has been reported in some previous articles. Most of them, however, have reported sesamoid bones of the metacarpophalangeal joint of the hand and of the interphalangeal (IP) joint of the thumb. The present study investigates the prevalence of sesamoid bones of the IP joint of the thumb and fingers. A retrospective review of radiologic views of the IP joints in the thumb or fingers was performed, including a total of 650 patients (1,096 thumbs or fingers). Sesamoid bones were found in the IP joint of the thumb at 67% (212 of 318), while the index, middle, ring, little f...

Deep fat of the face revisited
Abstract The midfacial deep fatty tissue has been divided into the buccal and parapharyngeal fat pads although the former carries several extensions in adults. Using histological sections of 15 large human fetuses, we demonstrated that the parapharyngeal fat pad corresponds to the major content of the prestyloid compartment of the parapharyngeal space or, simply, the prestyloid fat. The buccal and prestyloid fatty tissues were separated by the medial and lateral pterygoid muscles. In these tissues, superficial parts, corresponding to the lower body and the masseteric extension of the adult buccal fat pad, were well encapsu...

Is surgery the gold standard in the treatment of obstructive hypertrophic cardiomyopathy?
CONCLUSIONS Surgical myectomy, dual-chamber pacing and alcohol septal ablation are equally effective in reducing obstruction in case of correct indications. Dual-chamber pacing is indicated in functional reversible states characterized by excitation delay. Alcohol septal ablation is preferable in cases with midventricular obstruction and appropriate coronary anatomy. Surgical methods are indicated in anatomical irreversible changes and remain the gold standard for obstructive hypertrophic cardiomyopathy treatment.

Anatomy and Pathophysiology of the Pleura and Pleural Space
Pleural effusions are most often secondary to an underlying condition and may be the first sign of the underlying pathologic condition. The balance between the hydrostatic and oncotic forces dictates pleural fluid homeostasis. The parietal pleura has a more significant role in pleural fluid homeostasis. Its vessels are closer to the pleural space compared with its visceral counterpart; it contains lymphatic stomata, absent on visceral pleura, which are responsible for a bulk clearance of fluid. The diagnosis and successful treatment of pleural effusions requires a mixture of imaging techniques and pleural fluid analysis.

Aortic Valve Repair—Current Status, Indications, and Outcomes
Aortic valve repair is a new development with old roots. In the past 20 years, marked progress has been made in understanding the normal anatomy of the aortic valve and the interrelation between cusps and root. Aortic dilatation is the single most frequent pathogenetic factor in aortic regurgitation, accompanied by cusp pathology, that is, prolapse or congenital anomaly in most industrialized countries.

Cryotherapy reduces skeletal muscle damage after ischemia/reperfusion in rats.
Abstract The aim of this study was to analyze the effects of cryotherapy on the biochemical and morphological changes in ischemic and reperfused (I/R) gastrocnemius muscle of rats. Forty male Wistar rats were divided into control and I/R groups, and divided based on whether or not the rats were submitted to cryotherapy. Following the reperfusion period, biochemical and morphological analyses were performed. Following cryotherapy, a reduction in thiobarbituric acid-reactive substances and dichlorofluorescein oxidation levels were observed in I/R muscle. Cryotherapy in I/R muscle also minimized effects such as decrea...

Feasibility of real-time magnetic resonance imaging-guided electrophysiology studies in humans
Conclusion To our knowledge, this is the first series of patients with real-time MRI-guided placement of multiple catheters with subsequent performance of stimulation maneuvers. Besides the mentioned benefits, this technology still encounters several limitations, which have to be solved before application in a routine clinical setting. Challenges arise from delineation of precise surface electrocardiogram recordings in the MRI setting along with intracardiac electrograms, easier handling and visualization of catheters, facilitation of immediate defibrillation in the MRI setting and implementation of an active catheter tracking system.

Pitfalls in Image Guided Tissue Sampling in the Head and Neck
Image-guided tissue sampling is becoming increasingly important for management of head and neck cancers. Ultrasound-guided fine-needle aspiration (UG-FNA) is safe, effective, and has many advantages compared with palpation-guided FNA and computed tomography-guided FNA. The technique of UG-FNA is highly operator and experience dependent; however, understanding the complex anatomy, disease processes, and patterns of nodal spread in the head and neck make this technique ideal for the neuroradiologist. Proper technique and recognition of pitfalls are critical to successful UG-FNA. Computed tomography–guided FNA is valuable f...
