Personalized Meal Plans as An Intervention to Enhance Dash Diet Adherence in Hypertensive Adults
The Dietary Approach to Stop Hypertension (DASH) diet is more effective as a standalone treatment at lowering blood pressure than any pharmaceutical intervention alone, but adherence is poor and current interventions to improve adherence only show marginal improvements. Personalized meal plans are effective at improving diet adherence in other chronic conditions and may serve as an effective intervention for DASH diet adherence. In a randomized controlled trial, we will determine whether nutritional counseling plus personalized meal planning (intervention) improves DASH adherence more than nutritional counseling alone (control). We will randomize n=178 adults with primary hypertension to either the intervention or control condition and compare DASH adherence scores after 3- and 12-months. Adherence scores will be compared using Student’s t-tests and a 1.56-point change will be considered clinically significant. Improving DASH diet adherence has the potential to improve medical management of hypertension and lessen its massive social and economic burden
The wide-field, multiplexed, spectroscopic facility WEAVE : survey design, overview, and simulated implementation
Funding for the WEAVE facility has been provided by UKRI STFC, the University of Oxford, NOVA, NWO, Instituto de Astrofísica de Canarias (IAC), the Isaac Newton Group partners (STFC, NWO, and Spain, led by the IAC), INAF, CNRS-INSU, the Observatoire de Paris, Région Île-de-France, CONCYT through INAOE, Konkoly Observatory (CSFK), Max-Planck-Institut für Astronomie (MPIA Heidelberg), Lund University, the Leibniz Institute for Astrophysics Potsdam (AIP), the Swedish Research Council, the European Commission, and the University of Pennsylvania.WEAVE, the new wide-field, massively multiplexed spectroscopic survey facility for the William Herschel Telescope, will see first light in late 2022. WEAVE comprises a new 2-degree field-of-view prime-focus corrector system, a nearly 1000-multiplex fibre positioner, 20 individually deployable 'mini' integral field units (IFUs), and a single large IFU. These fibre systems feed a dual-beam spectrograph covering the wavelength range 366-959 nm at R ∼ 5000, or two shorter ranges at R ∼ 20,000. After summarising the design and implementation of WEAVE and its data systems, we present the organisation, science drivers and design of a five- to seven-year programme of eight individual surveys to: (i) study our Galaxy's origins by completing Gaia's phase-space information, providing metallicities to its limiting magnitude for ∼ 3 million stars and detailed abundances for ∼ 1.5 million brighter field and open-cluster stars; (ii) survey ∼ 0.4 million Galactic-plane OBA stars, young stellar objects and nearby gas to understand the evolution of young stars and their environments; (iii) perform an extensive spectral survey of white dwarfs; (iv) survey ∼ 400 neutral-hydrogen-selected galaxies with the IFUs; (v) study properties and kinematics of stellar populations and ionised gas in z 1 million spectra of LOFAR-selected radio sources; (viii) trace structures using intergalactic/circumgalactic gas at z > 2. Finally, we describe the WEAVE Operational Rehearsals using the WEAVE Simulator.PostprintPeer reviewe

A first molecular characterization of the scorpion telson microbiota of Hadrurus arizonensis and Smeringurus mesaensis.
Scorpions represent an ancient lineage of arachnids that have radiated across the globe and are incredibly resilient-since some thrive in harsh environments and can exist on minimal and intermittent feedings. Given the emerging importance of microbiomes to an organism's health, it is intriguing to suggest that the long-term success of the scorpion bauplan may be linked to the microbiome. Little is known about scorpion microbiomes, and what is known, concentrates on the gut. The microbiome is not limited to the gut, rather it can be found within tissues, fluids and on external surfaces. We tested whether the scorpion telson, the venom-producing organ, of two species, Smeringurus mesaensis and Hadrurus arizonensis, contain bacteria. We isolated telson DNA from each species, amplified bacterial 16S rRNA genes, and identified the collection of bacteria present within each scorpion species. Our results show for the first time that telsons of non-buthid scorpion species do indeed contain bacteria. Interestingly, each scorpion species has a phylogenetically unique telson microbiome including Mollicutes symbionts. This study may change how we view scorpion biology and their venoms

The phylogenetic tree was constructed using Maximum Likelihood, including a total of 312 sequences representing Mollicutes taxa. Scorpion sequences are in bold. Red collapsed regions indicate 12 sequences reported in this study from H. arizonensis and S. mesaensis. For an expanded version of this figure see S2 Fig.</p
Phylogenetic tree showing species-specific clades for telson bacteria isolated from <i>S</i>. <i>mesaensis</i> and <i>H</i>. <i>arizonensis</i>.
A Maximum Likelihood phylogeny was constructed based on the DNA sequences of 114 16S rRNA samples isolated from S. mesaensis (n = 32) and H. arizonensis (n = 82) telsons. Scorpion-specific clades are identified by vertical bars numbered 1–12 with samples from H. arizonensis indicated in black; S. mesaensis indicated in red. We considered clades to be scorpion-specific if they contained 3 or more taxa from a single scorpion species and were supported by bootstrap values greater than 70.</p
