To report the incidence, demographics, and clinical manifestations of neurofibromatosis type 1 among a population-based cohort of patients.

A prefix brachial plexus with two trunks and one anterior cord.

The brachial plexus presents a great variability in formation, division and branching pattern. Its variants are of immense importance during axillary and arm surgery and nerve blockade. The current case highlights a unilateral atypical formation of brachial plexus, the so called prefix, in which the C₄ root contributed a large branch to the superior trunk and further anastomosis with the inferior trunk. Thus, the prefix or high brachial plexus consisted of a superior and inferior trunk and one anterior co...


Nonsense-mediated mRNA decay of the ferric and cupric reductase mRNAs FRE1 and FRE2 in Saccharomyces cerevisiae.

The nonsense-mediated mRNA decay (NMD) pathway regulates mRNAs that aberrantly terminate translation. This includes aberrant mRNAs and functional natural mRNAs. Natural mRNA degradation by NMD is triggered by mRNA features and environmental cues. Saccharomyces cerevisiae encodes multiple proteins with ferric and cupric reductase activity. Here, we examined the regulation by NMD of two mRNAs, FRE1 and FRE2, encoding ferric and cupric reductases in S. cerevisiae. We found that FRE2 mRNAs are regulated by NMD ...

Bottom-up control of geographic variation in insect herbivory on wild cotton (Gossypium hirsutum) by plant defenses and climate.

The occurrence and amount of herbivory are shaped by bottom-up forces, primarily plant traits (e.g., defenses), and by abiotic factors. Addressing these concurrent effects in a spatial context has been useful in efforts to understand the mechanisms governing variation in plant-herbivore interactions. Still, few studies have evaluated the simultaneous influence of multiple sources of bottom-up variation on spatial variation in herbivory.

Safely surrendered infants in Los Angeles County: A medically vulnerable population.

As a means to provide safety for a population at great risk of harm through abandonment, every state in the United States now has laws and practices for the safe relinquishment of newborns and infants. However, there is no national database tracking the population of infants surrendered through such programs, and few states monitor these numbers. The primary aim of this study was therefore to examine the descriptive characteristics of infants who have been safely surrendered in a large, socio-economically d...

Ambivalence towards discourse of disaster resilience.

This paper investigates empirically how the international aid community (IAC)-donors and practitioners-considers and implements disaster resilience in a specific country setting, Nepal, and throughout the rest of the world. A key finding is that there is ambivalence about a concept that has become a discourse. On a global level, the IAC utilises the discourse of resilience in a cautiously positive manner as a bridging concept. On a national level, it is being used to influence the Government of Nepal, as we...

Development of dissociative force field for all-atomistic molecular dynamics calculation of fracture of polymers.

A dissociative force field for all-atomistic molecular dynamics calculations has been developed to investigate impact fracture of polymers accompanying dissociation of chemical bonds of polymer main chain. Energy of dimer molecules was evaluated as a function of both bond-length b and bond-angle θ by CASPT2 calculations, whose quality is enough to describe dissociation of chemical bonds. Because we found that the bond dissociation energy D decreases with increasing bond-angle, we employed the Morse-type fu...

The impact of crystal packing and aurophilic interactions on the luminescence properties in polymorphs and solvate of aroylacetylidegold(I) complexes.

The influence of the chemical substitution, crystal packing and aurophilic interactions of the gold(I) acetylide complexes type of Et₃PAu(C≡C)nCOAr (n=1,2) on their luminescent properties were examined. All described complexes undergo ligand scrambling in solution resulting in the formation of stable, easily isolated crystals containing [ArCO(C≡C)n]₂Au-(Et₃P)₂Au+ homoleptic species. In particular, we observed that (benzoylacetylide)gold(I) complex yields three crystal forms with strikingly diffe...

Density functional theory for molecular and periodic systems using density fitting and continuous fast multipole method: Stress tensor.

A full implementation of the analytical stress tensor for periodic systems is reported in the TURBOMOLE program package within the framework of Kohn-Sham density functional theory using Gaussian-type orbitals as basis functions. It is the extension of the implementation of analytical energy gradients (Lazarski et al., Journal of Computational Chemistry 2016, 37, 2518-2526) to the stress tensor for the purpose of optimization of lattice vectors. Its key component is the efficient calculation of the Coulomb c...

A Germylene Supported by Two 2-Pyrrolylphosphane Groups as Precursor to PGeP Pincer Square-Planar Group 10 Metal(II) and T-Shaped Gold(I) Complexes.

An efficient synthesis of 2-ditertbutylphosphanylmethylpyrrole (HpyrmPtBu2), by reacting 2-dimethylaminomethylpyrrole (HpyrmNMe2) with tBu2PH at 135 oC in the absence of any solvent, has allowed the preparation of the new PGeP germylene Ge(pyrmPtBu2)2 (1), by treating GeCl2(dioxane) with LipyrmPtBu2, in which the Ge atom is stabilized by intramolecular interactions with one (solid state) or both (solution) of its phosphane groups. Reactions of germylene 1 with Group 10 metal dichlorido complexes containing ...

A functional variant in the miR-142 promoter modulating its expression and conferring risk of Alzheimer disease.

Non-coding RNAs have been widely recognized as essential mediators of gene regulation. However, in contrast to protein-coding genes, much less is known about the influence of non-coding RNAs on human diseases. Here we examined the association of genetic variants located in primary microRNA sequences and long non-coding RNAs (lncRNAs) with Alzheimer disease (AD) by leveraging data from the largest genome-wide association meta-analysis of late-onset AD. Variants annotated to five miRNAs and ten lncRNAs (in 7 ...

EEG-based outcome prediction after cardiac arrest with convolutional neural networks: Performance and visualization of discriminative features.

Prognostication for comatose patients after cardiac arrest is a difficult but essential task. Currently, visual interpretation of electroencephalogram (EEG) is one of the main modality used in outcome prediction. There is a growing interest in computer-assisted EEG interpretation, either to overcome the possible subjectivity of visual interpretation, or to identify complex features of the EEG signal. We used a one-dimensional convolutional neural network (CNN) to predict functional outcome based on 19-chann...

Hematopoietic stem cell transplantation recovers insulin deficiency in type 1 diabetes mellitus associated with IPEX syndrome.

Immune dysregulation, polyendocrinopathy, enteropathy, and X-linked (IPEX) syndrome is an autoimmune disorder caused by the dysfunction of FOXP3, which leads to regulatory T (Treg) cell dysfunction and subsequently autoimmunity including type 1 diabetes mellitus (T1D). Presently, allogeneic hematopoietic stem cell transplantation (HSCT) is a potential curative therapy for IPEX syndrome, but not for T1D. Generally, after complete loss of pancreatic β-cells, HSCT cannot improve the prognosis of T1D. Here, we...

Combined and differential effects of alpha-thalassemia and HbF-quantitative trait loci in Senegalese hydroxyurea-free children with sickle cell anemia.

Our objective was to investigate the combined and differential effects of alpha-thalassemia -3.7 kb deletion and HbF-promoting quantitative trait loci (HbF-QTL) in Senegalese hydroxyurea (HU)-free children and young adults with sickle cell anemia (SCA).

Photoinduced energy- and electron-transfer processes in a side-to-face RuII-porphyrin/perylene-bisimide array.

A side-to-face array DPy-gPBI[Ru(4-tBuTPP)(CO)]2, based on a "green" perylene bisimide chromophore sandwiched between two RuII-porphyrins, has been prepared by self-assembly. Its photophysical properties have been characterized in detail by a combination of steady-state and time-resolved techniques upon selective excitation of the two different components. Different photoinduced processes are observed as a function of the excitation wavelength. Electron transfer quenching is attained upon "red light" excita...

Metformin reduces risk of varicose veins in type 2 diabetes patients.

Bilateral Lower Extremity Type I Complex Regional Pain Syndrome in a 21 yr-old Male After Bilateral Lung Transplant Responsive to Conservative Therapies: A Case Report.

Complex regional pain syndrome [CRPS] is a debilitating condition characterized by pain out of proportion to degree and timing of an injury or event. Symptoms are thought to be sympathetically driven manifesting as hair, nail and skin changes with allodynia. There is currently a lack of evidence and reported cases of CRPS-I developing after organ transplant procedures. Furthermore, there are also very few reported cases of bilateral CRPS-I affecting multiple limbs. This is the first reported case of bilater...

Assessing the role of extracellular signal-regulated kinases 1 and 2 in volume overload-induced cardiac remodelling.

Volume overload (VO) and pressure overload (PO) induce differential cardiac remodelling responses including distinct signalling pathways. Extracellular signal-regulated kinases 1 and 2 (ERK1/2), key signalling components in the mitogen-activated protein kinase pathways (MAPK), modulate cardiac remodelling during pressure overload (PO). This study aimed to assess their role in VO-induced cardiac remodelling as this was unknown.

Polyethylenimine "Snow": An Emerging Material for Efficient Carbon Removal.

Amine-functionalized solid adsorbents are one of the most promising alternatives to the conventional "amine scrubbing" for carbon capture with a number of prominent examples being reported. However, their widespread application in industry is unfulfilled due to their overall performance and complex fabrication, which relies on a porous support. In this "proof of concept" study, we report an approach for generating a new type of material called polyethylenimine (PEI) 'snow', which can be prepared for use in ...

Differential Isotope Labeling by Permethylation and Reversed-Phase Liquid Chromatography-Mass Spectrometry for Relative Quantification of Intact Neutral Glycolipids in Mammalian Cells.

Probing the role of glycolipids in health and disease warrants development of practical strategies to determine these molecules at the intact structural level, namely to simultaneously characterize and quantify the glycan and lipid moieties without breaking the linkage between them. Herein we present such an approach utilizing differential isotope labeling and reversed phase liquid chromatography-tandem mass spectrometry (RPLC-MS/MS) for structural characterization and relative quantification of intact neut...

Protein cross-interactions for efficient photosynthesis in the cassava cultivar SC205 relative to its wild species.

The underlying mechanisms of higher photosynthetic efficiency of cultivated cassava relative to its wild species are poorly understood. In the present study, proteins in leaves and chloroplasts were analyzed to compare the differences among the cultivar SC205, its wild ancestor W14 and the related species Glaziovii. The functions of differential proteins are associated with 10 ontology groups including photosynthesis, carbohydrate and energy metabolism, as well as potential signal pathway. The protein-prote...

High-Resolution Liquid Chromatography-Mass Spectrometry-Based Metabolomic Discrimination of -Type Crude Drugs and Comparison with Nuclear Magnetic Resonance Spectroscopy-Based Metabolomics.

Five -type crude drugs (40 samples) were classified using liquid chromatography-mass spectrometry (LC-MS)-based metabolomics. The following six flavonoid derivatives were identified as contributors from the loading plots of multivariate analysis: naringin (), neohesperidin (), neoeriocitrin (), narirutin (), hesperidin (), and 3,5,6,7,8,3',4'-heptamethoxyflavone (). Three coumarin derivatives, namely, meranzin (), meranzin hydrate (), and meranzin glucoside (), were also identified as contributors. Furtherm...

Clusters in Liquid Fatty Acids: Structure and Role in Nucleation.

Saturated fatty acids are used in many consumer products and have considerable promise as phase change materials (PCMs) for thermal energy storage, in part because they crystallize with minimal supercooling. The latter property correlates with the existence of molecular clusters in the liquid; when heated above a threshold temperature clusters do not immediately re-form on cooling, and supercooling results. Raman spectroscopy, density-functional theory (DFT) calculations, and small-angle X-ray scattering (S...

Atomistic Insights Into the Layered Microstructure and Time-Dependent Stability of BMIMPF Confined Within the Meso-Slit of Carbon.

Clarifying the microstructures and time-dependent stability of ionic liquids (ILs) within the confinement of the meso-slit of carbon is the first step to understand the intrinsic synergy effect between ILs and promising mesoporous carbon electrode. In this work, we adopted molecular dynamics to systematically investigate the behavior of [BMIM][PF6] in the 2.8 nm-wide meso-slit of carbon. The confined ILs formed a pronounced layered spatial distribution and can be divided into three distinct regions, namely,...
