Until recently autism spectrum disorder (ASD) was regarded as a neurodevelopmental condition with unknown causes and pathogenesis. In the footsteps of the revolution of genome technologies and genetics, and with its high degree of heritability, ASD became the first neuropsychiatric disorder for which clues towards molecular and cellular pathogenesis were uncovered by genetic identification of susceptibility genes. Currently several hundreds of risk genes have been assigned, with a recurrence below 1% in the ASD population...

Low reliability and reproducibility in heart failure models are well established. The purpose of the present study is to explore factors that affect model consistency of myocardial infarction (MI) in mice. METHODS: MI was induced by left coronary artery (LCA) ligation. The coronary artery was casted with resin and visualized with fluorescent imaging ex vivo. LCA characteristics and MI size were analyzed individually in each animal, and MI size was correlated with left ventricular (LV) function by echocardiography...

The survival rate of patients with congenital heart disease (CHD) has dramatically improved over the last 2 decades because of technological and surgical advances in diagnosis and treatment, respectively. The vast majority of CHD patients are, in fact, amenable to treatment by either device closure or surgery. Considering the wide spectrum of surgical procedures and complex native and derived anatomy, continuous and detailed follow-up is of paramount importance. Cardiac magnetic resonance and cardiac computed tomography angiography are the cornerstones of diagnosis and follow-up of CHD, allowing for comprehensive noninvasive assessment of the heart, coronary tree, and intrathoracic great vessels, along with both morphological and functional evaluation...

INTRODUCTION: Insular gliomas are heterogeneous lesions whose management presents multiple challenges for their tendency to affect young patients in good neurological and cognitive conditions, their deep anatomic location and proximity with critical functional and vascular structures. The appropriate management of insular gliomas requires a multidisciplinary evidence-centred teamwork grounded on the best anatomic, neurophysiological and oncological knowledge. The present study provides a reappraisal of the management of insular gliomas based on a systematic review of the literature with the aim of guiding clinicians in the management of such tumors...

INTRODUCTION: A typical feature of inferior glenoid fractures is a distal fragment separated from the glenoid fossa. In most cases, the inferior glenoid fractures are associated with a fracture of the scapular body. However, there are no detailed studies of inferior glenoid fractures, and only brief mentions can be found in the literature in this respect. MATERIAL AND METHODS: The basic group comprised 42 patients, with the mean age of 48 years, who sustained 42 fractures of the inferior glenoid...

Faulty postures due to sedentary lifestyle cause weakening of core muscles which contributes to increased incidence of musculoskeletal disorders (MSDs). Although a few research studies have quantified the core muscle activity in various yogic exercises used in rehabilitation programs, evidence correlating it to functional anatomy is scarce. Such information is important for exercise prescription when formulating treatment plans for MSDs. Therefore, the objective of this review article is to examine the literature and analyze the muscle activity produced across various yoga postures to determine which type of yoga posture elicits the highest activation for the core muscle in individuals...

Altered sensory processing has been an important feature of the clinical descriptions of autism spectrum disorder (ASD). There is evidence that sensory dysregulation arises early in the progression of ASD and impacts social functioning. This paper reviews behavioral and neurobiological evidence that describes how sensory deficits across multiple modalities (vision, hearing, touch, olfaction, gustation, and multisensory integration) could impact social functions in ASD. Theoretical models of ASD and their implications for the relationship between sensory and social functioning are discussed...

BACKGROUND: To describe the survival and health outcome status of young adults with an extracardiac Fontan procedure performed either as a primary or conversion (secondary) Fontan surgery. METHODS: The database of the Adult Congenital Heart disease service at the Royal Melbourne Hospital was interrogated to identify all adults who had undergone a primary extracardiac conduit Fontan (n=29) or a Fontan conversion with this procedure (n=8). We then determined vital status, age, original anatomy and functional status in early adulthood in both groups...

To describe the normal anatomy and histology of the adult coccygeal body (CB) and to discuss about the origin and function. Using immunohistochemistry, we examined 29 CBs found in 32 elderly donated cadavers without macroscopic pathology in the pelvis. The CB was usually located in or near the anococcygeal ligaments. It was almost always composed of multiple masses or nodules of round glomus cells (smooth muscle actin, or SMA++). However, the CB sometimes contained abundant dilated veins with scattered glomus cells...

Mouse models are invaluable for investigating the developmental etiology and molecular pathogenesis of structural birth defects. While this has been deployed for studying a wide spectrum of birth defects, mice are particularly valuable for modeling congenital heart disease, given they have the same four-chamber cardiac anatomy as in humans. We have developed the use of noninvasive fetal ultrasound together with micro-computed tomography (micro-CT) imaging for high throughput phenotyping of mice for congenital heart defects (CHD) and other developmental anomalies...

Disorders (differences) of sex development (DSD) are identified when there is atypical chromosomal, gonadal, or anatomic sex. Given the complexity of DSD conditions, the consensus guidelines recommend that affected individuals be evaluated and cared for by teams with expertise in DSD conditions. Obstetrician gynecologists are experts in genital and reproductive anatomy, hormonal function, fertility, sexuality, and obstetrics, allowing them to provide a unique and essential function within the DSD team. Furthermore, obstetrician gynecologists with expertise in Pediatric and Adolescent Gynecology may follow individuals from birth into adulthood and provide reproductive health care for all ages, allowing these patients to "grow up" with them...

The early olfactory system is organized in parallel, with numerous, specialized subsystems established by the modular and topographic projections of sensory inputs. While these anatomical sub-systems are in many cases demarcated by well-known marker genes, we stand to learn considerably more about their possible functional specializations from comprehensive, genome-scale descriptions of their molecular anatomy. Here, we leverage the resources of the Allen Brain Atlas (ABA)-a spatially registered compendium of gene expression for the mouse brain-to investigate the early olfactory system's genomic anatomy...

ABCF1 is an ABC transporter family protein that has been shown to regulate innate immune response and is a risk gene for autoimmune pancreatitis and arthritis. Unlike other members of ABC transporter family, ABCF1 lacks trans-membrane domains and is thought to function in translation initiation through an interaction with eukaryotic translation initiation factor 2 (eIF2). To study ABCF1 expression and function in development and disease, we used a single gene trap insertion in the Abcf1 gene in murine embryonic stem cells (ES cells) that allowed lineage tracing of the endogenous Abcf1 promoter by following the expression of a β-galactosidase reporter gene...

Wood is a renewable resource that can be employed for the production of second generation biofuels by enzymatic saccharification and subsequent fermentation. Knowledge on how the saccharification potential is affected by genotype-related variation of wood traits and drought is scarce. Here, we used three Populus nigra L. genotypes from habitats differing in water availability to (i) investigate the relationships between wood anatomy, lignin content and saccharification and (ii) identify genes and co-expressed gene clusters related to genotype and drought-induced variation in wood traits and saccharification potential...

Recent research has demonstrated the importance of global changes to the functional organization of brain network following stroke. Resting functional magnetic resonance imaging (R-fMRI) is a non-invasive tool that enables the measurement of functional connectivity (FC) across the entire brain while placing minimal demands on the subject. For these reasons, it is a uniquely appealing tool for studying the distant effects of stroke. However, R-fMRI studies rely on a number of premises that cannot be assumed without careful validation in the context of stroke...

Mayer-Rokitansky-Küster-Hauser syndrome is a rare disorder consisting of vaginal aplasia and other müllerian duct abnormalities. Urinary tract malfor-mations possibly leading to renal failure are also common. For these patients, kidney transplant remains the best option. However, aberrant anatomy and scarring from previous operations may actually preclude successful implantation of the graft. In this setting, careful pretransplant evaluation with high-resolution imaging studies and multidisciplinary planning are mandatory...
