The benefits of data sharing are well-established and an increasing number of policies require that data be shared upon publication of the main study findings. As data sharing becomes the new norm, there is a heightened need for additional resources to drive efficient data reuse. This article describes the development and implementation of the Data and Specimen Hub (DASH) by the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) to promote data sharing from NICHD-funded studies and enable researchers to comply with NIH data sharing policies...

Dietary salt intake has significant effects on arterial blood pressure and the development of hypertension. Mechanisms underlying salt-dependent changes in blood pressure remain poorly understood, and it is difficult to assess blood pressure salt-sensitivity clinically. Methods: We examined urinary levels of metabolites in 103 participants of the Dietary Approaches to Stop Hypertension (DASH)-Sodium trial after nearly 30 days on a defined diet containing high sodium (targeting 150 mmol sodium intake per day) or low sodium (50 mmol per day)...

Dietary Na recommendations are expressed as absolute amounts (mg/d) rather than as Na density (mg/kcal). Our objective was to determine whether the strength of the relationship of Na intake with blood pressure (BP) varied with energy intake. The DASH (Dietary Approaches to Stop Hypertension)-Sodium trial was a randomized feeding trial comparing 2 diets (DASH and control) and 3 levels of Na density. Participants with pre- or stage 1 hypertension consumed diets for 30 days in random order; energy intake was controlled to maintain body weight...

Ample epidemiological evidence suggests a strong correlation among diet, lifestyle factors and the onset and consolidation of dementia and Alzheimer's disease (AD). It has been demonstrated that AD, diabetes, obesity, insulin resistance, and cardiovascular disease are strongly interconnected pathologies. Preventive strategies and nutritional interventions seem to be promising approaches to delay neurocognitive decline and reduce the risk of AD and other non-psychiatric co-morbidities. In this regard, healthy dietary patterns, characterized by high intake of plant-based foods, probiotics, antioxidants, soy beans, nuts, and omega-3 polyunsaturated fatty acids, and a low intake of saturated fats, animal-derived proteins, and refined sugars, have been shown to decrease the risk of neurocognitive impairments and eventually the onset of AD...

Metabolic pathways reflect an organism's chemical repertoire and hence their elucidation and design have been a primary goal in metabolic engineering. Various computational methods have been developed to design novel metabolic pathways while taking into account several prerequisites such as pathway stoichiometry, thermodynamics, host compatibility, and enzyme availability. The choice of the method is often determined by the nature of the metabolites of interest and preferred host organism, along with computational complexity and availability of software tools...

Entomopathogenic fungi are rich sources of bioactive secondary metabolites that possess insecticidal properties. The present study reported a novel approach for the identification of insecticidal compounds produced by Lecanicillium lecanii 09 and to assess their toxicity against the diamondback moth Plutella xylostella L. The cyclic peptides groups of toxic substances were separated from L. lecanii 09 through submerged liquid state fermentation. The most abundant toxic metabolite, Bassianolide was purified by high-performance liquid chromatography (HPLC) and its molecular weight and purity were determined by Liquid chromatography - mass spectroscopy (LC-MS), Fourier transformed infrared spectroscopy (FT-IR), and H1 nuclear magnetic resonance (NMR) respectively...

PURPOSE: Subacromial impingement syndrome (SIS) is associated with low self-reported shoulder function, impairments in shoulder strength and range of motion (ROM), and pain. It is not known how the symptomatology associated with SIS is reflected in the choice of treatment. This study compares self-reported shoulder function, shoulder strength, ROM, and pain in patients with SIS considered candidates and non-candidates for subacromial decompression (SAD). METHOD: Self-reported shoulder function (Q-DASH and SPADI), maximum isometric muscle strength in shoulder abduction (Abd-strength) and external rotation (ER-strength), active abduction ROM (Abd-ROM) and passive internal rotation ROM (IR-ROM) were measured in a consecutive cohort of patients with SIS referred to an orthopedic outpatient clinic...

This paper demonstrates a unique and promising approach to study driver-bicyclist interactions from a driver's perspective by using in-vehicle sensory data from naturalistic driving studies. A total of 4789 events of drivers overtaking bicyclists were extracted from an existing naturalistic driving study in Michigan, United States. The vehicle lateral placement at the time of passing bicyclists was used as a surrogate safety measure. A number of factors were examined, including the lane marking type, the presence of a bike lane or paved shoulder, the presence of traffic, lane width, and driver distraction...

Graphene oxide (GO) reinforced cement nanocomposites open up a new path for sustainable concrete design. In this paper, reactive force-field molecular dynamics was utilized to investigate the structure, reactivity and interfacial bonding of calcium silicate hydrate (C-S-H)/GO nanocomposite functionalized by hydroxyl (C-OH), epoxy (C-O-C), carboxyl (COOH) and sulfonic (SO3 H) groups with a coverage of 10%. The silicate chains in the hydrophilic C-S-H substrate provided numerous non-bridging oxygen sites and counter ions (Ca ions) with high reactivity, which allowed interlayer water molecules to dissociate into Si-OH and Ca-OH...

Background: Open reduction internal fixation of displaced 3 and 4-part proximal humerus fractures is an effective treatment modality particularly for the younger age group, but it is not without complications. Fixed angled locking screw plates are the mainstay of fixation. The A.L.P.S. Proximal Humerus Plating System is a new implant that has smooth locking pegs in the place of humeral head screws to help reduce glenoid damage in the event of cut-out and is designed to sit low on the humerus in order to reduce the risk of subacromial impingement...
