BACKGROUND: This is one of the first studies to examine the structural brain anatomy and connectivity associated with an ADHD diagnosis and child as well as adult ADHD symptoms in young adults. It was hypothesized that an adult ADHD diagnosis and in particular childhood symptoms, are associated with widespread changes in the brain macro- and microstructure, which can be used to develop a morphometric biomarker for ADHD. METHODS: Voxel-wise linear regression models were used to examine structural and diffusion-weighted MRI data in 72 participants (31 young adults with ADHD and 41 controls without ADHD) in relation to diagnosis and the number of self-reported child and adult symptoms...

Intrathecal injection of fluorescein is a method for repairing cerebrospinal fluid fistulas. The most frequent surgical procedure is endonasal endoscopy and the purpose of injecting this dye is to locate the fistula. The anaesthesiologists usually perform the puncture, therefore it is necessary to review this method and to specify some anaesthetic considerations such as correct dosing, safe management protocols and medical-legal aspects. In this case-report we describe the pre, intra and postoperative protocol of action implemented in our department that basically consists of: obtaining a specific consent, prior neurological/ophthalmologic assessment to rule out hypertension and brain damage, use of corticosteroids and previous antihistamines, choosing the correct dose and concentration of intrathecal sodium fluorescein (maximum 1ml at a concentration of 5% diluted in 9ml of cerebrospinal fluid) and close intra and postoperative monitoring...

BACKGROUND: Loeys-Dietz syndrome (LDS) is an aggressive aortopathy with a proclivity for aortic aneurysm rupture and dissection at smaller diameters than other connective tissue disorders. We reviewed our surgical experience of children with LDS to validate our guidelines for prophylactic aortic root replacement (ARR). METHODS: We reviewed all children (younger than 18 years) with a diagnosis of LDS who underwent ARR at our institution. The primary endpoint was mortality, and secondary endpoints included complications and the need for further interventions...

In this paper, we present a numerical study of the pulsatile transitional flow crossing a severe real stenosis located right in front of the bifurcation between the right subclavian and right common carotid arteries. The simulation allows one to determine relevant features of this subject-specific flow, such as the pressure waves in the right subclavian and right common carotid arteries. We explain the subclavian steal syndrome suffered by the patient in terms of the drastic pressure drop in the right subclavian artery...

Hepatocyte mitochondrial aquaporin-8 (mtAQP8) works as a multifunctional membrane channel protein that facilitates the uptake of ammonia for its detoxification to urea as well as the mitochondrial release of hydrogen peroxide. Since early oligonucleotide microarray studies in liver of cholesterol-fed mice showed an AQP8 downregulation, we tested whether alterations of cholesterol content per se modulate mtAQP8 expression in human hepatocyte-derived Huh-7 cells. Cholesterol loading with methyl-β-cyclodextrin (mβCD):cholesterol complexes downregulated the proteolytic activation of cholesterol-responsive sterol regulatory element-binding protein (SREBP) transcriptions factors 1 and 2, and the expression of the target gene 3-hydroxy-3-methylglutaryl-CoA reductase (HMGCR)...

The mTOR pathway is a critical determinant of cell persistence and growth wherein mTOR complex 1 (mTORC1) mediates a balance between growth factor stimuli and nutrient availability. Amino acids or glucose facilitates mTORC1 activation by inducing RagA GTPase recruitment of mTORC1 to the lysosomal outer surface, enabling activation of mTOR by the Ras homolog Rheb. Thereby, RagA alters mTORC1-driven growth in times of nutrient abundance or scarcity. Here, we have evaluated differential nutrient-sensing dependence through RagA and mTORC1 in hematopoietic progenitors, which dynamically drive mature cell production, and hematopoietic stem cells (HSC), which provide a quiescent cellular reserve...

Cancer patients are at high risk of malnutrition due to several symptoms such as lack of appetite. The aim of this study was to determine the prevalence of different appetite disorders in cancer patients and their influence on dietary intake, nutritional status, and quality of life. We conducted a cross-sectional study of cancer patients at risk of malnutrition. Nutritional status was studied using Subjective Global Assessment, anthropometry, and grip strength. Dietary intake was evaluated with a 24-h recall, and patients were questioned about the presence of changes in appetite (none, anorexia, early satiety, or both)...

Sterol Carrier Protein 2 (SCP2) has been associated with lipid binding and transfer activities. However, genomic, proteomic, and structural studies revealed that it is an ubiquitous domain of complex proteins with a variety functions in all forms of life. High-resolution structures of representative SCP2 domains are available, encouraging a comprehensive review of the structural basis for its success. Most SCP2 domains pertain to three major families and are frequently found as stand-alone or at the C-termini of lipid related peroxisomal enzymes, acetyltransferases causing bacterial resistance, and bacterial environmentally important sulfatases...

As in most sensory systems electrosensory images in weakly electric fish are encoded in two parallel pathways, fast and slow. From the work on wave type electric fish these pathways are thought to encode the time and amplitude of electrosensory signals respectively. This article focuses on the primary afferents giving origin to the slow path of the pulse type weakly electric fish Gymnotus omarorum We found that burst duration coders respond with a high-frequency train of spikes to each electric organ discharge...
