Discuss or comment on this article.
Lung separation techniques in the morbidly obese patient undergoing thoracic or esophageal surgery may be at risk of complications during airway management. Access to the airway in the obese patient can be a challenge because they have altered airway anatomy, including a short and redundant neck, limited neck extension and accumulation of fat deposition in the pharyngeal wall contributing to difficult laryngoscopy. Securing the airway is the first priority in these patients followed by appropriate techniques for lung separation with the use of a single-lumen endotracheal tube and a bronchial blocker or another alternative ...

A 'neurocinematic' comparison provides clues about evolution of the human brainMonkeys are closely related to us and their brains have long served as an indispensable model for understanding how our own brain works. But we're separated from each other by millions of years of evolution, so there are some major differences between their brains and ours. On the one hand, we can't assume that the results from experiments on their brains can be generalized to humans. But on the other, a better understanding of our differences can provide important clues about the evolutionary forces that shaped the human brain. A new method may...

-Yong Wang
Plants must coordinate the regulation of biochemistry and anatomy to optimize photosynthesis and water-use efficiency. The formation of stomata, epidermal pores that facilitate gas exchange, is highly coordinated with other aspects of photosynthetic development. The signalling pathways controlling stomata development are not fully understood, although mitogen-activated protein kinase (MAPK) signalling is known to have key roles. Here we demonstrate in Arabidopsis that brassinosteroid regulates stomatal development by activating the MAPK kinase kinase (MAPKKK) YDA (also known as YODA). Genetic analyses indicate t...

'Victimhood is something that happens but when you turn it into an identity you're psychically and politically finished'One day, Jacqueline Rose came across a troubling passage in Proust's A la recherche du temps perdu. The narrator, Marcel, lies beside his sleeping lover Albertine and masturbates against her. "It seemed to me at those moments," writes Proust in Carol Clark's recent Penguin translation, "that I possessed her more completely, like an unconscious part of dumb nature." Professor Rose, feminist and psychoanalytic critic, bristled. "I thought 'This is ridiculous – she'd have woken up by now!' I had my feminis...

Conclusion Dynamic FDG PET detected decreased cerebral glucose metabolism early after perinatal hypoxia in piglets. The decrease in CMRgl may indicate early changes of mild cerebral hypoxia–ischaemia. No significant effect of hyperoxic resuscitation on the degree
of hypometabolism was found in this early phase after hypoxia. Cerebral FDG PET can provide new insights into mechanisms of
perinatal hypoxic–ischaemic injury where early detection plays an important role in instituting therapy.

Abstract
Stereology offers a number of tools for the analysis of sections in microscopy (which usually provide only two-dimensional information) for the purpose of estimating geometric quantities, such as volume, surface area, length or number of particles (cells or other structures). The use of these tools enables recovery of the three-dimensional information that is inherent in biological tissues. This review uses the liver as a paradigm for summarizing the most commonly used state-of-the-art methods for quantitation in design-based stereology. Because it is often relevant to distinguish hyperplasia and hypertrop...

Abstract
The corpus callosum displays considerable morphological variability between individuals. Although some characteristics are thought to differ between male and female brains, there is no agreement regarding the source of this variation. Biomedical imaging and geometric morphometrics have provided tools to investigate shape and size variation in terms of integration and correlation. Here we analyze variations at the midsagittal outline of the corpus callosum in a sample of 102 young adults in order to describe and quantify the pattern of covariation associated with its morphology. Our results suggest that the...

In brain mapping research, parameterized 3-D surface models are of great interest for statistical comparisons of anatomy, surface-based registration, and signal processing. Here, we introduce the theories of continuous and discrete surface Ricci flow, which can create Riemannian metrics on surfaces with arbitrary topologies with user-defined Gaussian curvatures. The resulting conformal parameterizations have no singularities and they are intrinsic and stable. First, we convert a cortical surface model into a multiple boundary surface by cutting along selected anatomical landmark curves. Secondly, we conformally parameteriz...

AbstractDivalent manganese ion (Mn2+) is a widely used T1 contrast agent in manganese‐enhanced MRI studies to visualize functional neural tracts and anatomy in the brain in vivo. In animal studies, Mn2+ is administered at a dose that will maximize the contrast, while minimizing its toxic effects. In rodents, systemic administration of Mn2+ via intravenous injection has been shown to create unique MRI contrast in the brain at a maximum dose of 175 mg kg−1. However, intravenous administration of Mn2+ results in faster bioelimination of excess Mn2+ from the plasma due to a steep concentration gradient between plasma and b...

We report the case of a 2‐week‐old girl born at term (by vaginal delivery and without antenatal or perinatal events) who was referred as having “bilateral talipes and bilateral proximal symphalangism of little and ring fingers.” The “talipes” was atypical with marked equinus and varus, but no cavus or adductus of the midfoot. Her mother had both symphalangism (absence of proximal interphalangeal joints) of middle, ring, and little fingers bilaterally and fixed pes planus with a rigid fixed hindfoot—and these deformities had also been present from birth. The maternal grandmother was similarly affected. However...

AbstractJacob Winslow was a Dutch born, French naturalized anatomist and physician whose contributions to medicine are abundant. His importance to medicine is undisputed. His personal life included a religious crisis that resulted in his estrangement from his family, but afforded him patrons in Paris to continue his work. Following this conversion, he changed his name to that of his catechist and was rechristened Jacques Benigne Wilson. His respect as an expert was well deserved, and he held several prominent positions during his career in Paris. His main work, Exposition anatomique de la structure du corps humain, was pub...

AbstractThe safe and successful performance of pericardiocentesis demands a working and specific knowledge of anatomy. Misunderstanding of anatomy may result in failure or serious complications. This review attempts to aid understanding of the anatomical framework, pitfalls, and complications of pericardiocentesis. Pericardiocentesis is carried out for aspiration of blood from the pericardial cavity in cases of cardiac tamponade and symptomatic pericardial effusion. In addition, this technique may be used for the diagnosis of neoplastic effusions, purulent pericarditis, and introduction of cytotoxic agents into the pericar...

Discuss or comment on this article.
Conclusions The tested single-row repair using a modified suture configuration achieved superior results in three-dimensional measurements
of cyclic displacement compared to the tested double-row suture-bridge repair. The results were dependent on the initial rupture
size of the rotator cuff tear. Furthermore, significant differences were found between tendon subregions of the rotator cuff
with significantly higher gap formation for the anterior compared to the posterior subregions.

Abstract The aim of our study was to evaluate the effect of Orchis anatolica roots ethanol extraction on alloxan-induced diabetic rats. Thirty-six albino rats (200 g) were used in this experiment and
divided into six groups. Diabetes was induced in five rat groups by a single intraperitoneal injection of alloxan (150 mg/kg
body weight). After hyperglycemia was conformed, one rat group was considered as diabetic control and one group was treated
with glibenclamide (10 mg/kg body weight/daily) where the remaining three groups received daily treatments with three different
doses of O. anatolica e...

Abstract
Increasing photosynthesis in C3 species has been identified as an approach to increase the yield of crop plants. Most of our knowledge of photosynthetic performance has come from studies in which plants were grown in controlled growth conditions but plants in natural environments have to cope with unpredictable and rapidly changing conditions. Plants adapt to the light environment in which they grow and this is demonstrated by the differences in anatomy and morphology of leaves in sun and shade leaves. Superimposed on this are the dynamic responses of plants to rapid changes in the light environment that o...

We present an online resource that provides a convenient way to study and query fly brain anatomy, expression and genetic data. We extended the newly developed BrainName nomenclature for the adult fly brain into a logically structured ontology that relates a comprehensive set of published neuron classes to the brain regions they innervate. The Virtual Fly Brain interface allows users to explore the structure of the Drosophila brain by browsing 3D images of a brain with subregions displayed as coloured overlays. An integrated query mechanism allows complex searches of underlying anatomy, cells, expression and other data fro...
