Periventricular Microglial Cells Interact with Dividing Precursor Cells in the Nonhuman Primate and Rodent Prenatal Cerebral Cortex.

J Comp Neurol 2018 Dec 15. Epub 2018 Dec 15.

Department of Pediatrics, School of Medicine, UC Davis, Davis, CA.

Cortical proliferative zones have been studied for over 100 years, yet recent data has revealed that microglial cells constitute a sizeable proportion of ventricular zone cells during late stages of cortical neurogenesis. Microglia begin colonizing the forebrain after neural tube closure and during later stages of neurogenesis populate regions of the developing cortex that include the proliferative zones. We previously showed that microglia regulate the production of cortical cells by phagocytosing neural precursor cells (NPCs), but how microglia interact with NPCs remains poorly understood.

Holt-Oram syndrome: clinical and molecular description of 78 patients with TBX5 variants.

Eur J Hum Genet 2018 Dec 14. Epub 2018 Dec 14.

CHU Lille, Clinique de Génétique, 59000, Lille, France.

Holt-Oram syndrome (HOS) is an autosomal dominant condition characterised by the association of congenital heart defect (CHD), with or without rhythm disturbances and radial defects, due to TBX5 variants. The diagnosis is challenged by the variability of expression and the large phenotypic overlap with other conditions, like Okihiro syndrome, TAR syndrome or Fanconi disease. We retrospectively reviewed 212 patients referred for suspicion of HOS between 2002 and 2014, who underwent TBX5 screening. Read More

The Drying Kinetics of Salt Solution Droplets: Water Evaporation Rates and Crystallisation.

J Phys Chem B 2018 Dec 14. Epub 2018 Dec 14.

The drying and crystallisation of solution droplets is a problem of broad relevance, determining the micro-structures of particles formed in spray drying, the phase of particles delivered by, for example, aerosol formulations for inhalation therapies, and the impact of aerosols on radiative forcing and climate. The ephemeral nature of free-droplets, particularly when considering the drying kinetics of droplets with highly volatile constituents, has often precluded the accurate measurement of transient properties such as droplet size and composition, preventing the robust assessment of predictive models of droplet drying rates, nucleation and crystallisation. Here, we report novel measurements of the drying kinetics of individual aqueous sodium chloride solution droplets using a comparative-kinetics electrodynamic balance to isolate and trap single aerosol droplets (radius ~ 25 µm).

Sublaminar organization of the human subplate: developmental changes in the distribution of neurons, glia, growing axons and extracellular matrix.

J Anat 2018 Dec 13. Epub 2018 Dec 13.

Croatian Institute for Brain Research, School of Medicine, University of Zagreb, Zagreb, Croatia.

The objective of this paper was to collect normative data essential for analyzing the subplate (SP) role in pathogenesis of developmental disorders, characterized by abnormal circuitry, such as hypoxic-ischemic lesions, autism and schizophrenia. The main cytological features of the SP, such as low cell density, early differentiation of neurons and glia, plexiform arrangement of axons and dendrites, presence of synapses and a large amount of extracellular matrix (ECM) distinguish this compartment from the cell-dense cortical plate (CP; towards pia) and large fiber bundles of external axonal strata of fetal white matter (towards ventricle). For SP delineation from these adjacent layers based on combined cytological criteria, we analyzed the sublaminar distribution of different microstructural elements and the associated maturational gradients throughout development, using immunocytochemical and histological techniques on postmortem brain material (Zagreb Neuroembryological Collection).

Endocytosis acts as transport pathway in wood.

New Phytol 2018 Dec 12. Epub 2018 Dec 12.

Department of Plant Developmental Biology, Institute of Experimental Biology, Faculty of Biological Sciences, University of Wrocław, Kanonia 6/8, 50-328, Wrocław, Poland.

In trees, dead and living cells of secondary xylem (wood) function collectively, rendering cell-to-cell communication challenging. Water and solutes are transported over long distances from the roots to the aboveground organs via vessels, the main component of wood, and then radially over short distances to the neighboring cells. This enables proper functioning of trees and integrates whole-plant activity. Read More

Dev Neurobiol 2018 Dec 12. Epub 2018 Dec 12.

Department of Biology, University of North Florida, Jacksonville, Florida.

Radial glial cells are crucial in vertebrate neural development and regeneration. It has been recently proposed that this neurogenic cell type might be older than the chordate lineage itself and might have been present in the last common deuterostome ancestor. Here, we summarize the results of recent studies on radial glia in echinoderms, a highly regenerative phylum of marine invertebrates with shared ancestry to chordates. Read More

Remote ischaemic preconditioning increases serum extracellular vesicle concentrations with altered micro-RNA signature in CABG patients.

Acta Anaesthesiol Scand 2018 Dec 11. Epub 2018 Dec 11.

Klinik für Anästhesiologie und Intensivmedizin, Universitätsklinikum Essen, Universität Duisburg-Essen, Essen, Germany.

Background: Remote ischaemic preconditioning (RIPC) can attenuate myocardial ischaemia/reperfusion injury but its underlying mechanisms remain largely unknown. Recently, extracellular vesicles (EVs) containing microRNAs (miRNAs) were shown to mediate distant intercellular communication that may be involved in cardioprotection. We tested the hypothesis that RIPC in anaesthetized patients undergoing coronary artery bypass (CABG) surgery results in the release of EVs from the ischaemic/reperfused arm into the blood stream harbouring cardioprotective miRNAs.

Measurement of the radial mode spectrum of photons through a phase-retrieval method.

Opt Lett 2018 Dec;43(24):6101-6104

We propose and demonstrate a simple and easy-to-implement projective-measurement protocol to determine the radial index p of a Laguerre-Gaussian (LGpl) mode. Our method entails converting any specified high-order LGp0 mode into a near-Gaussian distribution that matches the fundamental mode of a single-mode fiber (SMF) through the use of two phase screens (unitary transforms) obtained by applying a phase-retrieval algorithm. The unitary transforms preserve the orthogonality of modes before the SMF and guarantee that our protocol can, in principle, be free of crosstalk. Read More

Suppression of Tearing Modes by Radio Frequency Current Condensation.

Phys Rev Lett 2018 Nov;121(22):225001

Princeton Plasma Physics Laboratory, Princeton University, Princeton, New Jersey 08544, USA.

Currents driven by radio frequency (rf) waves in the interior of magnetic islands can stabilize deleterious tearing modes in tokamaks. Present analyses of stabilization assume that the local electron acceleration is unaffected by the presence of the island. However, the power deposition and electron acceleration are sensitive to the perturbation of the temperature. Read More

Neurovascular Coupling Remains Intact During Incremental Ascent to High Altitude (4240 m) in Acclimatized Healthy Volunteers.

Front Physiol 2018 28;9:1691. Epub 2018 Nov 28.

Department of Biology, Mount Royal University, Calgary, AB, Canada.

Neurovascular coupling (NVC) is the temporal link between neuronal metabolic activity and regional cerebral blood flow (CBF), supporting adequate delivery of nutrients. Exposure to high altitude (HA) imposes several stressors, including hypoxia and hypocapnia, which modulate cerebrovascular tone in an antagonistic fashion. Whether these contrasting stressors and subsequent adaptations affect NVC during incremental ascent to HA is unclear. Read More

Nanoscale Core-Shell Hyperbolic Structures for Ultralow Threshold Laser Action: An Efficient Platform for the Enhancement of Optical Manipulation.

ACS Appl Mater Interfaces 2018 Dec 13. Epub 2018 Dec 13.

Plasmonic material has been emerged with multi-functionalities for its remarkable tailoring light emission, reshaping density of states (DOS) and focusing subwavelength light. However, restricted by its propagation loss and narrowband resonance in nature, it is a challenge issue for plasmonic material to provide a broadband DOS to advance its application. Here, we develop a novel nanoscale core-shell hyperbolic structure that possesses a remarkably coupling effect inside the multishell nanoscale composite owing to a higher DOS and longer time of collective oscillations of the electrons than the plasmonic-based pure metal nanoparticles.

Suppression of axial growth by boron incorporation in GaAs nanowires grown by self-catalyzed molecular beam epitaxy.

Nanotechnology 2019 Feb;30(6):065602

Center for Micro- and Nanostructures, Institute for Solid State Electronics, TU Wien, A-1040 Vienna, Austria.

The addition of boron to GaAs nanowires grown by self-catalyzed molecular beam epitaxy was found to have a strong effect on the nanowire morphology, with axial growth greatly reduced as the nominal boron concentration was increased. Transmission electron microscopy measurements show that the Ga catalyst droplet was unintentionally consumed during growth. Concurrent radial growth, a rough surface morphology and tapering of nanowires grown under boron flux suggest that this droplet consumption is due to reduced Ga adatom diffusion on the nanowire sidewalls in the presence of boron.

The Hippo Pathway Prevents YAP/TAZ-Driven Hypertranscription and Controls Neural Progenitor Number.

Dev Cell 2018 Dec 25;47(5):576-591.e8. Epub 2018 Oct 25.

Department of Developmental Neurobiology, St. Jude Children's Research Hospital, Memphis, TN 38105, USA. Electronic address:

The Hippo pathway controls the activity of YAP/TAZ transcriptional coactivators through a kinase cascade. Despite the critical role of this pathway in tissue growth and tumorigenesis, it remains unclear how YAP/TAZ-mediated transcription drives proliferation. By analyzing the effects of inactivating LATS1/2 kinases, the direct upstream inhibitors of YAP/TAZ, on mouse brain development and applying cell-number-normalized transcriptome analyses, we discovered that YAP/TAZ activation causes a global increase in transcription activity, known as hypertranscription, and upregulates many genes associated with cell growth and proliferation.

Holt-Oram syndrome (HOS) is an autosomal dominant disorder characterized by congenital cardiac defects and congenital deformities of the upper limbs. Herein, we report the case of a 2-year-old patient presenting with clinical diagnostic criteria of HOS with interatrial and interventricular communication associated with hip dysplasia and upper limb reduction composed of radial ray anomaly. A novel de novo, potentially pathogenic variant in the gene at NM_181486. Read More

Structure and Dynamics of the Hydration Shell: Spatially Decomposed Time Correlation Approach.

J Chem Theory Comput 2018 Dec 11. Epub 2018 Dec 11.

Molecular simulations provide insight into solvation structures and dynamics with unparalleled spatial and temporal resolution. Here, we take advantage of this fact and develop a set of generally applicable computational tools for a detailed analysis of the hydration shell around an ionic or molecular solute. These tools allow us to quantify and visualize orientationally-resolved radial distribution functions as well as distance-resolved orientational time-correlation functions of water molecules surrounding the solute.

Safe Casting and Reliable Cusp Reconstruction Assisted by Micro-Computed Tomographic Scans of Fossil Teeth.

Anat Rec (Hoboken) 2018 Dec 8. Epub 2018 Dec 8.

Department of Anthropology, The Ohio State University, 4034 Smith Laboratory, 174 West 18th Ave., Columbus, OH 43210, USA.

Dental replicas are frequently utilized in paleoanthropological studies of perikymata and enamel hypoplasia. However, fossil teeth are often fragile and worn, causing two problems: (1) the risk of damage by removing enamel fragments when impression-making material is separated from the fossil tooth surface, and (2) the need to reconstruct worn portions of the crown to assess perikymata number, distribution, and hypoplasia timing. This study presents the advantages of μCT data of canines and lateral incisors for (1) detecting cracks along the enamel-dentine junction (EDJ) which could cause damage when casting, and (2) reliably and non-destructively reconstructing worn or broken cusps.

Prognostic implications of markers of the metabolic phenotype in human cutaneous melanoma.

Br J Dermatol 2018 Dec 7. Epub 2018 Dec 7.

Instituto de Investigación Hospital 12 de Octubre, Universidad Complutense de Madrid, Madrid, Spain.

Background: Reprogramming of energy metabolism to enhanced aerobic glycolysis has been defined as a hallmark of cancer.

Objective: To investigate the role of the mitochondrial proteins, β-subunit of the H -ATP synthase (β-F1-ATPase), and heat-shock protein 60 (HSP60), and the glycolytic markers, glyceraldehyde-3-phosphate dehydrogenase (GAPDH) and pyruvate kinase M2 (PKM2), as well as the bioenergetic cellular (BEC) index, in melanoma progression.

Material And Methods: The expression of energy metabolism proteins were assessed on a set of different melanoma cells representing the natural biological history of the disease: primary cultures of melanocytes, radial (WM35) and vertical (WM278) growth phases, and poorly (C81-61-PA) and highly (C8161-HA) aggressive melanoma cells.

Characterization of thin gelatin hydrogel membranes with balloon properties for dynamic tissue engineering.

Biopolymers 2018 Dec 8:e23241. Epub 2018 Dec 8.

Department of Micro- and Nanotechnology, The Danish National Research Foundation and Villum Foundation's Center for Intelligent Drug Delivery and Sensing Using Microcontainers and Nanomechanics (IDUN), Technical University of Denmark, Kongens Lyngby, Denmark.

Cell or tissue stretching and strain are present in any in vivo environment, but is difficult to reproduce in vitro. Here, we describe a simple method for casting a thin (about 500 μm) and soft (about 0.3 kPa) hydrogel of gelatin and a method for characterizing the mechanical properties of the hydrogel simply by changing pressure with a water column.

Catheter Cardiovasc Interv 2018 Dec 11. Epub 2018 Dec 11.

Department of Cardiology, American Hospital of Paris and Hôpital Foch, Suresnes, France.

Since its introduction by Lucien Campeau three decades ago, percutaneous radial artery approach at the forearm has been shown to provide advantages over the femoral approach and has become the standard approach for coronary angiography and intervention. Though infrequent, vascular complications still remain, mainly radial artery occlusion. Therefore, a more distal radial approach at the snuffbox or at the dorsum of hand has been suggested, initially by anethesiologists for perioperative patient monitoring, and more recently by Babunashvili et al.

Trans-radial closure of coronary artery fistulae using Amplatzer vascular plug IV: A case series.

Catheter Cardiovasc Interv 2018 Dec 7. Epub 2018 Dec 7.

Interventional Cardiology Unit, Ospedale Papa Giovanni XXIII, Bergamo, Italy.

Background: Trans-catheter closure of coronary artery fistulae (CAF) has become a successful alternative to cardiac surgery with excellent results and acceptable low rate of complications. Different techniques and devices are available to treat the extreme anatomical variability of CAF.

Aim: We retrospectively describe our case series of five patients trans-radially treated using an Amplatzer vascular plug IV (AVP-IV) with telescoping catheter technique. Read More
