The interpretation of the figure of the prophet Jonah by Michelangelo on the ceiling of the sistine chapel: anatomical urological vision
CONCLUSIONS: This description helps to confirm the relationship of the Renaissance art with the human anatomy; science has been much studied in this period. The design of a cross section of the penis is revealed with the two cavernous bodies with the septum between them and the spongy body. Considering the circumstances in which Michelangelo had painted, subjectivity was fundamental due to religious motivations added to the vigorous implications of a limited scientific knowledge typical of that era.

Radial Styloid Fractures
Radial styloid fractures can occur in isolation or in association with other injuries, including complex intra-articular distal radius fractures, carpal fractures, carpal dislocations, and radiocarpal dislocations. The anatomy surrounding the radial styloid is complex, and complications related to surgical approach, treatments, and symptomatic hardware can occur. Operative treatments vary according to the injury pattern present, and pattern recognition is the key to optimizing treatment of these injuries. Outcomes are related to the precision of the reconstruction as well as the magnitude of the injury; better results are ...

An Anatomical Study of the Watershed Line on the Volar, Distal Aspect of the Radius: Implications for Plate Placement and Avoidance of Tendon Ruptures
Conclusions: The watershed line might not be a distinct line, and it corresponds to the distal margin of the pronator fossa in the lateral half of the volar radius and to a hypothetical line between the distal and proximal lines in the medial half. The medial and lateral bony prominences on the volar radius should be key structures for accurate plate placement to avoid flexor tendon injury. Clinical relevance: The present study suggests bony landmarks for positioning a volar locking plate.

The body as a living bioreactor: a feasibility study of pedicle flaps for tracheal transplantation
Abstract Reconstruction of long-segment tracheal stenosis remains problematic. Ex vivo transplantation of stem cell-derived tracheas has been established in humans using external tissue bioreactors. These bioreactors, however, are not widely accessible. Thus, we are developing a rotational flap-based “internal bioreactor” to allow in vivo stem cell engraftment in a pre-vascularized recipient bed. This muscle will also then serve as a carrier for the transplanted trachea during rotation into position for airway reconstruction. Herein, we present a study investigating the feasibility of two pedicle muscle ...

Accessing Flash Content on the iPad
Apple’s iPad tablet, along with the iPhone and iPod Touch mobile devices, cannot natively play content that is Flash-based, like some videos, interactive sites, tutorials and games. The reason that Apple made the decision to not allow Flash to operate on these devices is debated in online forums, but Apple’s official published reason can be summed up by saying that the late Steve Jobs disagreed with Flash being a controlled and closed system. If this decision is something you’re interested in knowing more about, here is Jobs’s open letter on the issue. Adobe itself (the company behind Flash) has annou...

Melanoma cell-derived factors stimulate hyaluronan synthesis in dermal fibroblasts by upregulating HAS2 through PDGFR-PI3K-AKT and p38 signaling
Abstract In many cancers hyaluronan content is increased, either by tumor cells or the surrounding stromal cells and this increased hyaluronan content correlates with unfavorable clinical prognosis. In the present work, we studied the effects of melanoma cell (aggressive melanoma cell line C8161)-derived factors on fibroblast hyaluronan synthesis, intracellular signaling, MMP expression and invasion. Treatment of the fibroblast cultures with melanoma cell conditioned medium (CM) caused accumulation of hyaluronan in the culture medium and formation of thick pericellular hyaluronan coat and hyaluronan cables. ...

Distance-to-Agreement Investigation of Tomotherapy's Bony Anatomy-Based Autoregistration and Planning Target Volume Contour-Based Optimization
Conclusions: We find that there is an average improvement of approximately 1 mm in terms of maxDTA on the PTV going from 4-dof bony anatomy-based autoregistration to the 4-dof contour-based optimization. Pearson correlation analysis of the 2 4-dof optimizations suggests that uncertainties due to deformation and inadequate resolution account for much of the compensating parameters, but pitch variation also makes a statistically significant contribution.

Multidetector computed tomography assessment of cardiac comorbidity in patients with chronic obstructive pulmonary disease.
Abstract Cardiac comorbidity is one of the most important prognostic factors in lung disease, especially in chronic obstructive pulmonary disease (COPD). The imaging techniques available for the study of this systemic manifestation concomitant with COPD include heart catheterization, transthoracic echocardiography, and magnetic resonance imaging. Multidetector computed tomography (MDCT) represents a significant advance in this field because it enables the acquisition of simultaneous studies of the cardiopulmonary anatomy that go beyond anatomic and morphologic analysis to include a functional approach to this condi...

Gamma oscillations in the human basal ganglia.
Abstract Interest in beta activity in the basal ganglia has mushroomed since it was first identified in the subthalamic nucleus of patients with Parkinson's disease in Jonathan Dostrovsky's landmark paper (Levy et al., 2000). Here we consider a less explored phenomenon; namely gamma frequency synchronisation of neurons in the basal ganglia. Gamma oscillations have been reported in a distributed network involving the basal ganglia, thalamus and motor cortex, and have been described in a wide range of diseases as well as during increased arousal and voluntary movement. In Parkinson's disease, gamma activity is promot...

CT fractional flow reserve: the next level in non-invasive cardiac imaging.
Abstract The haemodynamic effect of a coronary artery stenosis is a better predictor of prognosis than anatomical lumen obstruction. Until recently, no individual non-invasive test could provide both accurate coronary anatomy and lesion-specific myocardial ischaemia. However, computer tomography (CT) fractional flow reserve, which can be calculated from a standard CT coronary angiogram, was recently demonstrated to accurately detect and rule out the haemodynamic significance of individual coronary artery stenoses.

Brief communication: The human humerus from the broken hill mine, kabwe, zambia
AbstractThe distal half of a right human humerus (E.898), recovered ex situ in 1925 by Hrdlička at the Broken Hill Mine, Kabwe, Zambia, has figured prominently in assessments of Middle Pleistocene Homo postcranial variation and of the phylogenetic polarity and functional anatomy of Pleistocene Homo upper limb morphology. Reassessment of distal humeral features that distinguish modern human and some archaic Homo humeri, especially relative olecranon breadth and medial and lateral pillar thicknesses, confirm previous studies placing it morphologically close to recent humans, as well as possibly to Early Pleistocene Homo.

A middle mesenteric artery
Abstract In 114 cases of the transverse colon isolated from cadavers (50 male, 64 female), anatomical examinations of the arterial system of the colon were performed. Arteriograms were obtained after dissecting and contrasting the colonic vessels with Mixobar contrast. In one case, on arteriography of the colon with its mesentery isolated from a 55-year-old male cadaver, a rare anatomical variant was found. The third mesenteric artery originated directly from the aorta—halfway between the superior and inferior mesenteric arteries and ascended obliquely in the direction of the hepatic flexure of the colon. ...

Aortic constriction and the relevance of physiologic research
This article does inform on highly relevant themes, such as ventricle-ventricle interaction, timing of RV remodeling, and the molecular signature of RV profibrotic reactions. It may also open the door to a very untraditional way of managing the remodeled RV. The problem of the hypertrophied yet not decompensated RV is typically solved by an early repair of the anatomy, such as early repair of tetralogy of Fallot for example. No one would consider “banding” the aorta to allow for reverse RV remodeling. What, however, about the thick, fibrotic RV in an older patient with unrepaired pulmonary stenosis? Should we consider,...

Normal anatomy by three-dimensional ultrasound in the second and third trimesters
Summary: Fetal brain is rapidly developing and changing its appearance week by week during pregnancy. It is quite difficult to observe detailed structure of the brain by conventional transabdominal sonography. Transvaginal high-resolution ultrasound and three-dimensional (3D) ultrasound have been establishing sonoembryology in the first trimester as well as neurosonography. It is possible to observe the whole brain structure by magnetic resonance imaging in the latter half of pregnancy but transvaginal high-resolution 3D ultrasound is also a powerful modality for understanding brain anatomy. As for brain vascularization, m...

The study of the breast by magnetic resonance imaging (MRI) has created greater interest following the possibility of obtaining multiplanar thin slice images with clear delineation of the breast anatomy. The application of MRI in the future study of the breast is mentioned for the first time by Higgins in 1990 in the book Magnetic Resonance of the Body, and since that time, the use of MR in the study of the breast has become a routine examination of the breast. Many books have been written on its technical aspects and diagnostic value, but very often, they are deficient in the number of cases presented and illustrated.

Tunicamycin Inhibits PDGF-BB-Induced Proliferation and Migration of Vascular Smooth Muscle Cells Through Induction of HO-1.
In this study, we found that pretreatment with tunicamycin (Tm), an ER stress inducer, significantly inhibited platelet-derived growth factor (PDGF)-BB-induced VSMC proliferation and migration in a dose-dependent manner without causing significant apoptosis. Tm stimulated the expression of the antioxidant gene heme oxygenase-1 (HO-1) both at the transcriptional and translational levels, while reducing phosphorylation and activation of mitogen-activated protein (MAP) kinases. The negative regulative effects of Tm were associated with a decrease in cyclins and cyclin-dependent kinases (CDKs) activation. More importantly, HO-...

Reversed intestinal malrotation with concurrent cecal carcinoma
AbstractA 57‐year‐old man was admitted with a type 2 (ulcerated with clear margin) cancer in the cecum. Contrast‐enhanced CT showed that the superior mesenteric vein was anterior to the superior mesenteric artery, and the patient was suspected of having intestinal malrotation. A laparoscopic‐assisted ileocecal resection was performed. At operation, the cecum and the transverse colon passed through the root of the mesentery behind the superior mesenteric artery with the duodenum. Therefore, this was thought to be a reversed‐type intestinal malrotation. After the operation, 3D‐CT colonography with duodenography i...

Postnatal alteration of collapsin response mediator protein 4 mRNA expression in the mouse brain.
Abstract Collapsin response mediator protein 4 (CRMP4) is a molecular marker for immature neurons but only limited information is available on the spatiotemporal gene expression changes of Crmp4 in the developing rodent. In the present study, the variation of CRMP4 mRNA expression in the mouse brain was investigated from postnatal day (PD) 0 (the day of birth) to adulthood by in situ hybridization. The hybridization signals were broadly detected on PD0 and regional changes in expression during development were noted. Expression patterns of CRMP4 mRNA were classified into the following three types: (i) signals that ...

The oblique branch trap in the harvest of the anterolateral thigh myocutaneous flap
AbstractA 67‐year‐old man with squamous cell carcinoma underwent reconstruction with a free anterolateral thigh myocutaneous flap. Unroofing the skin perforators found that the skin perforators originated from the oblique branch of the lateral circumflex femoral artery with no connections with the descending branch. Thus, the flap was harvested based on the oblique branch, leaving the descending branch in situ. Reconstruction was completed uneventfully and he had an excellent outcome at 1‐year follow‐up. The anterolateral thigh myocutaneous flap was reputed to be a technically easy flap to harvest. The perforators ...

The impact of these short-term educational approaches on longer-term retention and actual clinical application warrants further investigation. PMID: 22822190 [PubMed - as supplied by publisher]

Advances in Molecular Genetics of Hirschsprung's Disease.
Abstract Hirschsprung's disease (HSCR) is a developmental disorder of the enteric nervous system, which occurs due to the failure of neural crest cells to fully colonize the gut during embryonic development. It is characterized by the absence of the enteric ganglia in a variable length of the intestine. Substantial progress has been made in understanding the genetic basis of HSCR with the help of advanced genetic analysis techniques and animal models. More than 11 genes have been found to be involved in the pathogenesis of HSCR. The RET gene is the most important susceptibility gene involved in HSCR with both codin...

Initial clinical experience with the coherex FlatStent™ and FlatStent™ EF PFO closure system for in‐tunnel PFO closure: Results of the Coherex‐EU study
Conclusion:This initial study of the Coherex FlatStent/FlatStent EF PFO Closure System demonstrated the potential for in‐tunnel PFO closure. The in‐tunnel Coherex FlatStent EF may offer an alternative to septal repair devices for PFO closure in appropriately selected patients; however, further investigation will be necessary to establish the best use of this device. © 2012 Wiley Periodicals, Inc.

Observations on torquaratorid acorn worms (Hemichordata, Enteropneusta) from the North Atlantic with descriptions of a new genus and three new species
AbstractEnteropneusts in the family Torquaratoridae were imaged using still and video cameras in the deep North Atlantic and then collected by remotely operated vehicles. From this material, we describe Yoda purpurata n. gen, n. sp., Tergivelum cinnabarinum n. sp., and Allapasus isidis n. sp. Individuals of the first two species were browsing completely exposed on the sea floor, whereas the specimen of the last species was encountered floating ~1 m above the sea floor. Living specimens of Y. purpurata were 12–19 cm long and had a dark reddish‐purple proboscis, collar, and genital wings (folded dorsally over the anter...

Global and regional alterations of hippocampal anatomy in long‐term meditation practitioners
AbstractStudies linking meditation and brain structure are still relatively sparse, but the hippocampus is consistently implicated as one of the structures altered in meditation practitioners. To explore hippocampal features in the framework of meditation, we analyzed high‐resolution structural magnetic resonance imaging data from 30 long‐term meditators and 30 controls, closely matched for sex, age, and handedness. Hippocampal formations were manually traced following established protocols. In addition to calculating left and right hippocampal volumes (global measures), regional variations in surface morphology were d...
