Abstract
The debilitating effects of Parkinson's disease (PD) progress over time and are pathophysiologically characterized by the formation of Lewy bodies due to the accumulation of α-synuclein aggregates resulting in the death of dopaminergic neurons. In the present study, we determined cell death pathways activated by acute exposure to 6-hydroxydopamine (6-OHDA) in differentiated LUHMES cells empirically followed by a 24 h toxin free interval, henceforth termed as washout/recovery period. Acute 6-OHDA exposure led to morphological changes in LUHMES cells and resulted in significant loss of neurite length and neurite thickness. Generation of reactive oxygen species and loss of mitochondrial membrane potential in the neuronal processes were persistent even after the recovery period. Our results show that 6-OHDA exposure leads to significant reduction in expression of mitochondrial OXPHOS complexes I, II, and IV and activation of caspase mediated apoptotic cell death cascade as observed by enhanced protein expression of cleaved-PARP-1 and cleaved-Caspase-3. Immunofluorescence microscopy approach confirmed that cell death occurs independent of the AIF translocation to the nucleus. Our experimental model, led to a ∼5-fold lower α-synuclein monomer expression and, interestingly, resulted in loss of protein ubiquitination in whole cell lysates. Altogether, this work provides evidence of multiple pathways targeted by 6-OHDA in differentiated LUHMES cells and expands research avenues for addressing the knowledge gap regarding the effect of 6-OHDA in the ubiquitin proteasome system for PD therapies.

Abstract
INTRODUCTION Self-measured blood pressure monitoring with support is an evidence-based intervention that helps patients control their blood pressure. This systematic economic review describes how certain intervention aspects contribute to effectiveness, intervention cost, and intervention cost per unit of the effectiveness of self-measured blood pressure monitoring with support. METHODS Papers published between data inception and March 2021 were identified from a database search and manual searches. Papers were included if they focused on self-measured blood pressure monitoring with support and reported blood pressure change and intervention cost. Papers focused on preeclampsia, kidney disease, or drug efficacy were excluded. Quality of estimates was assessed for effectiveness, cost, and cost per unit of effectiveness. Patient characteristics and intervention features were analyzed in 2021 to determine how they impacted effectiveness, intervention cost, and intervention cost per unit of effectiveness. RESULTS A total of 22 studies were included in this review from papers identified in the search. Type of support was not associated with differences in cost and cost per unit of effectiveness. Lower cost and cost per unit of effectiveness were achieved with simple technologies such as interactive phone systems, smartphones, and websites and where providers interacted with patients only as needed. DISCUSSION Some of the included studies provided only limited information on key outcomes of interest to this review. However, the strength of this review is the systematic collection and synthesis of evidence that revealed the associations between the characteristics of implemented interventions and their patients and the interventions' effectiveness and cost, a useful contribution to the fields of both research and implementation.

Abstract
Application of genetic data to species delimitation often builds confidence in delimitations previously hypothesized using morphological, ecological, and geographic data and frequently yields recognition of previously-undescribed cryptic diversity. However, a recent critique of genomic data-based species delimitation approaches is that they have the potential to conflate population structure with species diversity, resulting in taxonomic oversplitting. The need for an integrative approach to species delimitation, in which molecular, morphological, ecological, and geographic lines of evidence are evaluated together, is becoming increasingly apparent. Here, we integrate phylogenetic, population genetic, and coalescent analyses of genome-wide sequence data with investigation of variation in multiple morphological traits to delimit species within the Antarctic barbeled plunderfishes (Artedidraconidae: Pogonophryne). Pogonophryne currently comprises 29 valid species, most of which are distinguished solely by variation in ornamentation of the mental barbel that projects from the lower jaw, a structure previously shown to vary widely within a single species. However, our genomic and phenotypic analyses result in a dramatic reduction in the number of distinct species recognized within the clade, providing evidence to support the recognition of no more than six species. We propose to synonymize 24 of the currently recognized species with five species of Pogonophryne. We find genomic and phenotypic evidence for a new species of Pogonophryne from specimens collected in the Ross Sea. Our findings represent a rare example in which application of molecular data provides evidence of taxonomic oversplitting on the basis of morphology, clearly demonstrating the utility of an integrative species delimitation framework.

Abstract
Southern Ocean ecosystems are globally important and vulnerable to global drivers of change, yet they remain challenging to study. Fish and squid make up a significant portion of the biomass within the Southern Ocean, filling key roles in food webs from forage to mid-trophic species and top predators. They comprise a diverse array of species uniquely adapted to the extreme habitats of the region. Adaptations such as antifreeze glycoproteins, lipid-retention, extended larval phases, delayed senescence, and energy-conserving life strategies equip Antarctic fish and squid to withstand the dark winters and yearlong subzero temperatures experienced in much of the Southern Ocean. In addition to krill exploitation, the comparatively high commercial value of Antarctic fish, particularly the lucrative toothfish, drives fisheries interests, which has included illegal fishing. Uncertainty about the population dynamics of target species and ecosystem structure and function more broadly has necessitated a precautionary, ecosystem approach to managing these stocks and enabling the recovery of depleted species. Fisheries currently remain the major local driver of change in Southern Ocean fish productivity, but global climate change presents an even greater challenge to assessing future changes. Parts of the Southern Ocean are experiencing ocean-warming, such as the West Antarctic Peninsula, while other areas, such as the Ross Sea shelf, have undergone cooling in recent years. These trends are expected to result in a redistribution of species based on their tolerances to different temperature regimes. Climate variability may impair the migratory response of these species to environmental change, while imposing increased pressures on recruitment. Fisheries and climate change, coupled with related local and global drivers such as pollution and sea ice change, have the potential to produce synergistic impacts that compound the risks to Antarctic fish and squid species. The uncertainty surrounding how different species will respond to these challenges, given their varying life histories, environmental dependencies, and resiliencies, necessitates regular assessment to inform conservation and management decisions. Urgent attention is needed to determine whether the current management strategies are suitably precautionary to achieve conservation objectives in light of the impending changes to the ecosystem.

Abstract

Many molecular machines
are built from modular components with
well-defined motile capabilities, such as axles and wheels. Hinges
are particularly useful, as they provide the minimum flexibility needed
for a simple and pronounced conformational change. Compounds with
multiple stable conformers are common, but molecular hinges almost
exclusively operate via dihedral rotations rather than truly hinge-like
clamping mechanisms. An ideal molecular hinge would better reproduce
the behavior of hinged devices, such as gates and tweezers, while
remaining soluble, scalable, and synthetically versatile. Herein,
we describe two isomeric macrocycles with clamp-like open and closed
geometries, which crystallize as separate polymorphs but interconvert
freely in solution. An unusual one-pot addition cyclization reaction
was used to produce the macrocycles on a multigram scale from inexpensive
reagents, without supramolecular templating or high-dilution conditions.
Using mechanistic information from NMR kinetic studies and at-line
mass spectrometry, we developed a semicontinuous flow synthesis with
maximum conversions of 85–93% and over 80% selectivity for
a single isomer. The macrocycles feature voids that are sterically
protected from guests, including reactive species such as fluoride
ions, and could therefore serve as chemically inert hinges for adaptive
supramolecular receptors and flexible porous materials.

Abstract
Abstract
Introduction
To critically appraise the outcomes of different techniques described for total lower lip reconstruction in a retrospective study, where these factors were specifically documented.
Method
A comprehensive literature review was conducted over a 20-year period using Pudmed and EMBASE using the search terms “local”, “regional”, “functional”, “total lip reconstruction”. Data collected included: patient demographics, aetiology for lip reconstruction, reconstruction methods and outcomes (functional, aesthetic, complications).
Results
204 patients from 28 studies were included. Squamous cell carcinoma of the lower lip (93.1%) was the most common cause for reconstruction. Of all the flaps, 67% were local flaps, 8.5% were regional flaps and 24.6% were free flaps. Most studies used a wide variety of objective and subjective outcome measures whereas only 4 used validated scoring systems to determine functional and aesthetic outcomes.
Conclusions
Despite a myriad of different techniques described, we are currently unable to determine a superior technique. Given the ultimate goal of reconstruction is to restore form and function, we recommend the use of a standardised recording of functional and aesthetic outcome measure to allow comparison and identification of best technique for lower lip reconstruction to optimise patients' outcomes.

Abstract
CONTEXT There is a need for knowledge translation to advance health equity in the prevention and control of cardiovascular disease and type 2 diabetes. One recommended strategy is engaging community health workers (CHWs) to have a central role in related interventions. Despite strong evidence of effectiveness for CHWs, there is limited information examining the impact of state CHW policy interventions. This article describes the application of a policy research continuum to enhance knowledge translation of CHW workforce development policy in the United States. METHODS During 2016-2019, a team of public health researchers and practitioners applied the policy research continuum, a multiphased systematic assessment approach that incorporates legal epidemiology to enhance knowledge translation of CHW workforce development policy interventions in the United States. The continuum consists of 5 discrete, yet interconnected, phases including early evidence assessments, policy surveillance, implementation studies, policy ratings, and impact studies. RESULTS Application of the first 3 phases of the continuum demonstrated (1) how CHW workforce development policy interventions are linked to strong evidence bases, (2) whether existing state CHW laws are evidence-informed, and (3) how different state approaches were implemented. DISCUSSION As a knowledge translation tool, the continuum enhances dissemination of timely, useful information to inform decision making and supports the effective implementation and scale-up of science-based policy interventions. When fully implemented, it assists public health practitioners in examining the utility of different policy intervention approaches, the effects of adaptation, and the linkages between policy interventions and more distal public health outcomes.

Abstract
Many interesting target guest molecules have low symmetry, yet most methods for synthesising hosts result in highly symmetrical capsules. Methods of generating lower symmetry pores are thus required to maximise the binding affinity in host-guest complexes. Herein, we use mixtures of tetraaldehyde building blocks with cyclohexanediamine to access low-symmetry imine cages. Whether a low-energy cage is isolated can be correctly predicted from the thermodynamic preference observed in computational models. The stability of the observed structures depends on the geometrical match of the aldehyde building blocks. One bent aldehyde stands out as unable to assemble into high-symmetry cages-and the same aldehyde generates low-symmetry socially self-sorted cages when combined with a linear aldehyde. We exploit this finding to synthesise a family of low-symmetry cages containing heteroatoms, illustrating that pores of varying geometries and surface chemistries may be reliably accessed through computational prediction and self-sorting.

Abstract
SARS-CoV-2, the virus that causes coronavirus disease 2019 (COVID-19), is thought to spread from person to person primarily by the respiratory route and mainly through close contact (1). Community mitigation strategies can lower the risk for disease transmission by limiting or preventing person-to-person interactions (2). U.S. states and territories began implementing various community mitigation policies in March 2020. One widely implemented strategy was the issuance of orders requiring persons to stay home, resulting in decreased population movement in some jurisdictions (3). Each state or territory has authority to enact its own laws and policies to protect the public's health, and jurisdictions varied widely in the type and timing of orders issued related to stay-at-home requirements. To identify the broader impact of these stay-at-home orders, using publicly accessible, anonymized location data from mobile devices, CDC and the Georgia Tech Research Institute analyzed changes in population movement relative to stay-at-home orders issued during March 1-May 31, 2020, by all 50 states, the District of Columbia, and five U.S. territories.* During this period, 42 states and territories issued mandatory stay-at-home orders. When counties subject to mandatory state- and territory-issued stay-at-home orders were stratified along rural-urban categories, movement decreased significantly relative to the preorder baseline in all strata. Mandatory stay-at-home orders can help reduce activities associated with the spread of COVID-19, including population movement and close person-to-person contact outside the household.

Abstract
SARS-CoV-2, the virus that causes coronavirus disease 2019 (COVID-19), is thought to spread from person to person primarily by the respiratory route and mainly through close contact (1). Community mitigation strategies can lower the risk for disease transmission by limiting or preventing person-to-person interactions (2). U.S. states and territories began implementing various community mitigation policies in March 2020. One widely implemented strategy was the issuance of orders requiring persons to stay home, resulting in decreased population movement in some jurisdictions (3). Each state or territory has authority to enact its own laws and policies to protect the public's health, and jurisdictions varied widely in the type and timing of orders issued related to stay-at-home requirements. To identify the broader impact of these stay-at-home orders, using publicly accessible, anonymized location data from mobile devices, CDC and the Georgia Tech Research Institute analyzed changes in population movement relative to stay-at-home orders issued during March 1-May 31, 2020, by all 50 states, the District of Columbia, and five U.S. territories.* During this period, 42 states and territories issued mandatory stay-at-home orders. When counties subject to mandatory state- and territory-issued stay-at-home orders were stratified along rural-urban categories, movement decreased significantly relative to the preorder baseline in all strata. Mandatory stay-at-home orders can help reduce activities associated with the spread of COVID-19, including population movement and close person-to-person contact outside the household.

Abstract
Spatially resolved soft materials, such as vesicles and microgels, have shown promise as selective adsorbents and microscale reaction vessels. However, spatiotemporal control of aggregation can be difficult to achieve. In this study, nickel(ii) chloride and a dipyridyl oligo(urea) ligand were combined in a vapour-diffusion setup to produce a localised spheroidal aggregate at the liquid-vapour interface. This aggregate forms via the self-assembly and fusion of monodisperse colloids and grows until its weight is no longer counterbalanced by surface tension. A simple physical model reveals that this process, termed lilypad aggregation, is possible only for surface energies that favour neither bulk aggregation nor the growth of an interfacial film. These surface energies dictate the final size and shape of the aggregate and may be estimated through visual monitoring of its changing morphology. Lilypad aggregates sequester metal from the surrounding sol and can be collected manually from the surface of the liquid.

Abstract
Objective: It is widely accepted that the early debridement of burns improves outcome. There is increasing evidence that enzymatic debridement is an effective technique for removal of full-thickness and deep-dermal burns, reducing blood loss and often the need for autologous skin grafting by avoiding over excision of the burn. We aim to highlight the potential use of this form of debridement as an alternative to surgical management in patients with electronic cigarette (e-cigarette)-associated flame burn injuries. Methods: This case series presents the use of Nexobrid (MediWound Ltd, Israel), a non-surgical, bromelain-based enzymatic debridement technique, in patients with deep partial-thickness burns (range: 1–3% total body surface area), avoiding the need for autologous skin grafting. Results: Burn wounds in two patients healed within 14 days without complications or the need for further surgical intervention. Another patient required further dressings after discharge but failed to attend follow-up appointments. These results are comparable with those reported by others using conservative management of e-cigarette burns. Conclusion: The authors wish to raise awareness of the potential for a combination of thermal and chemical burns related to e-cigarette explosions. Chemical burns should be excluded by pH testing of the burn wound. From our experience, small e-cigarette-associated flame burns can be considered for management with enzymatic debridement.

Abstract
Aim: Umbilical cord blood (UCB) sourced allografts are promising interventions for tissue regeneration. As applications of these allografts and regulations governing them continue to evolve, we were prompted to identify parameters determining their quality, safety and regenerative potential. Materials & methods: Flow-cytometry, mass-spectrometry, protein multiplexing, nanoparticle tracking analysis and standard biological techniques were employed. Results: Quality attributes of a uniquely processed UCB-allograft (UCBr) were enumerated based on identity (cell viability, immunophenotyping, proteomic profiling, and quantification of relevant cytokines); safety (bioburden and microbiological screening), purity (endotoxin levels) and potency (effect of UCBr on chondrocytes and mesenchymal stem cells derived exosomes). These attributes were stable up to 24 months in cryopreserved UCBr. Conclusion: We identified a comprehensive panel of tests to establish the clinical efficacy and quality control attributes of a UCB-sourced allograft.

Abstract
CONTEXT Cardiovascular disease in the U.S. accounted for healthcare cost and productivity losses of $330 billion in 2013-2014 and diabetes accounted for $327 billion in 2017. The impact is disproportionate on minority and low-SES populations. This paper examines the available evidence on cost, economic benefit, and cost effectiveness of interventions that engage community health workers to prevent cardiovascular disease, prevent type 2 diabetes, and manage type 2 diabetes. EVIDENCE ACQUISITION Literature from the inception of databases through July 2016 was searched for studies with economic information, yielding nine studies in cardiovascular disease prevention, seven studies in type 2 diabetes prevention, and 13 studies in type 2 diabetes management. Analyses were done in 2017. Monetary values are reported in 2016 U.S. dollars. EVIDENCE SYNTHESIS The median intervention cost per patient per year was $329 for cardiovascular disease prevention, $600 for type 2 diabetes prevention, and $571 for type 2 diabetes management. The median change in healthcare cost per patient per year was -$82 for cardiovascular disease prevention and -$72 for type 2 diabetes management. For type 2 diabetes prevention, one study saw no change and another reported -$1,242 for healthcare cost. One study reported a favorable 1.8 return on investment from engaging community health workers for cardiovascular disease prevention. Median cost per quality-adjusted life year gained was $17,670 for cardiovascular disease prevention, $17,138 (mean) for type 2 diabetes prevention, and $35,837 for type 2 diabetes management. CONCLUSIONS Interventions engaging community health workers are cost effective for cardiovascular disease prevention and type 2 diabetes management, based on a conservative $50,000 benchmark for cost per quality-adjusted life year gained. Two cost per quality-adjusted life year estimates for type 2 diabetes prevention were far below the $50,000 benchmark.

AIM Umbilical cord blood (UCB) finds frequent applications in regenerative medicine. We evaluated the role of cytokines present in a uniquely processed, UCB-derived cellular allograft product (UCBp). MATERIALS & METHODS Luminex multiplex assay and standard cell biology methods were employed. RESULTS Study with allografts from 33 donors identified 44 quantifiable cytokines in the UCBp derived conditioned media (CM). The UCBp-CM elevated proliferation and migration rates of mesenchymal stem cells (MSCs) and bone marrow stromal cells. Moreover, UCBp-CM induced secretion of VEGF-A and osteoprotegerin, which promoted angiogenesis of endothelial cells and positively influenced the osteogenic differentiation of MSCs, respectively. CONCLUSION Cytokines in UCBp stimulate cellular processes important for bone regeneration, making UCBp an excellent candidate for potential applications in orthopedic procedures like bone non-union and spinal fusion.

Abstract
Supramolecular gel phase crystallization offers a new strategy for drug polymorph screening and discovery. In this method, the crystallization outcome depends on the interaction between solute and gel fibre. While supramolecular gels have shown success in producing new polymorphs and crystals with novel morphologies, role of the gel and nature of gel-solute interaction remains largely unexplored. The present study aims to provide a comprehensive picture of the structural evolution of a supramolecular gel produced from a bis(urea) based gelator (G) in the presence of a polymorphic drug carbamazepine (CBZ). The structural aspects of the gel have been assessed by single crystal X-ray analysis, X-ray powder diffraction (XRPD) and solid state NMR spectroscopy. Small Angle Neutron Scattering (SANS) has been used to follow the changes in gel structure in the presence of CBZ. Visual evidence from morphological study and structural evolution observed at a macroscopic level from rheological measurements, shows good agreement with the SANS results. The concentration of the gelator and the relative proportion of G to CBZ were found to be crucial factors in determining the competitive nucleation events involving gelation and crystallization. At a critical G to CBZ ratio the effect of CBZ on gel structure was maximum and fiber bundling in the gel was found to be critically affected. This study offers important information about how the interplay of gelator assembly and gel-solute interactions can fine-tune the nucleation events in a supramolecular gel phase crystallization.

Abstract
Notothenioids are a clade of ∼120 species of marine fishes distributed in extreme southern hemisphere temperate near-shore habitats and in the Southern Ocean surrounding Antarctica. Over the past 25 years, molecular and morphological approaches have redefined hypotheses of relationships among notothenioid lineages as well as their relationships among major lineages of percomorph teleosts. These phylogenies provide a basis for investigation of mechanisms of evolutionary diversification within the clade and have enhanced our understanding of the notothenioid adaptive radiation. Despite extensive efforts, there remain several questions concerning the phylogeny of notothenioids. In this study, we deploy DNA sequences of ∼100,000 loci obtained using RADseq to investigate the phylogenetic relationships of notothenioids and to assess the utility of RADseq loci for lineages that exhibit divergence times ranging from the Paleogene to the Quaternary. The notothenioid phylogenies inferred from the RADseq loci provide unparalleled resolution and node support for several long-standing problems including, (1) relationships among species of Trematomus, (2) resolution of Indonotothenia cyanobrancha as the sister lineage of Trematomus, (3) the deep paraphyly of Nototheniidae, (4) the paraphyly of Lepidonotothen s.l., (5) paraphyly of Artedidraco, and 6) the monophyly of the Bathydraconidae. Assessment of site rates demonstrates that RADseq loci are similar to mtDNA protein coding genes and exhibit peak phylogenetic informativeness at the time interval during which the major Antarctic notothenioid lineages originated and diversified. In addition to providing a well-resolved phylogenetic hypothesis for notothenioids, our analyses quantify the predicted utility of RADseq loci for Cenozoic phylogenetic inferences.

Abstract
AIM Placental allografts used for tissue regeneration differ in membrane compositions and processing techniques. A uniquely folded dehydrated binate amniotic membrane (DBAM) was biochemically characterized to evaluate its potential role in wound healing. METHODS Histology, Luminex-based immunoassay and standard in vitro cell biology techniques were employed. RESULTS Histological staining confirmed that the DBAM was chorion free with epithelial cell layer of the respective amnion membranes facing outward. DBAM had quantifiable levels of relevant cytokines that induced proliferation and migration while bolstering secretory activity of the cells. DBAM retained biological efficacy at a broad range of temperatures. CONCLUSION Cytokines in DBAM stimulate bone marrow stromal and stem cells that may lead to tissue regeneration and wound healing in a clinical setup.

Abstract
The [4 + 4] photoreactivity of the anthracene derivative 9-(methylaminomethyl)anthracene (MAMA) has been investigated in solution, gel medium and in the solid state. While quantitative formation of the cyloaddition photoproduct was achieved upon irradiation at λ = 365 nm of ethanol solutions of MAMA, only partial and slow conversion was detected in gels of low molecular weight gelators, and solid-state reactivity was not observed due to the unfavourable relative orientation of the anthracene moieties in the crystal. In hexafluorophosphate, tetrafluoroborate and nitrate silver(i) complexes, however, 9-(methylaminomethyl)anthracene exhibits a more favourable mutual orientation for the aromatic fragments, and [4 + 4] photoreactivity resulted. All compounds were structurally characterized via single crystal and/or X-ray powder diffraction and by Raman spectroscopy; this last technique proved effective in detection of the photoproduct in all solid state complexes.

Abstract
Advances in the field of supramolecular chemistry have made it possible, in many situations, to reliably engineer soft materials to address a specific technological problem. Particularly exciting are "smart" gels that undergo reversible physical changes on exposure to remote, non-invasive environmental stimuli. This review explores the development of gels which are transformed by heat, light and ultrasound, as well as other mechanical inputs, applied voltages and magnetic fields. Focusing on small-molecule gelators, but with reference to organic polymers and metal-organic systems, we examine how the structures of gelator assemblies influence the physical and chemical mechanisms leading to thermo-, photo- and mechano-switchable behaviour. In addition, we evaluate how the unique and versatile properties of smart materials may be exploited in a wide range of applications, including catalysis, crystal growth, ion sensing, drug delivery, data storage and biomaterial replacement.

Abstract
The Community Preventive Services Task Force recommended five interventions for cardiovascular disease prevention between 2012 and 2015. Systematic economic reviews of these interventions faced challenges that made it difficult to generate meaningful policy and programmatic conclusions. This paper describes the methods used to assess, synthesize, and evaluate the economic evidence to generate reliable and useful economic conclusions and address the comparability of economic findings across interventions. Specifically, steps were taken to assess completeness of data and identify the components and drivers of cost and benefit. Except for the intervention cost of self-measured blood pressure monitoring intervention, either alone or with patient support, all cost and benefit estimates were standardized as per patient per year. When possible, intermediate outcomes were converted to quality-adjusted life year. Differences within and between interventions were considered to generate economic conclusions and inform their comparability. The literature search period varied among interventions. This analysis was completed in 2016. Although team-based care, self-measured blood pressure monitoring with patient support, and self-measured blood pressure monitoring within team-based care were found to be cost effective, their cost-effectiveness estimates were not comparable because of differences in the intervention characteristics. Lack of enough data or incomplete information made it difficult to reach an overall economic finding for the other interventions. The Community Guide methods discussed here may help others conducting systematic economic reviews of public health interventions to respond to challenges with the synthesis of evidence and provide useful findings for public health decision makers.

Abstract
CONTEXT The health and economic burden of hypertension, a major risk factor for cardiovascular disease, is substantial. This systematic review evaluated the economic evidence of self-measured blood pressure (SMBP) monitoring interventions to control hypertension. EVIDENCE ACQUISITION The literature search from database inception to March 2015 identified 22 studies for inclusion with three types of interventions: SMBP used alone, SMBP with additional support, and SMBP within team-based care (TBC). Two formulae were used to convert reductions in systolic BP (SBP) to quality-adjusted life years (QALYs) to produce cost per QALY saved. All analyses were conducted in 2015, with estimates adjusted to 2014 U.S. dollars. EVIDENCE SYNTHESIS Median costs of intervention were $60 and $174 per person for SMBP alone and SMBP with additional support, respectively, and $732 per person per year for SMBP within TBC. SMBP alone and SMBP with additional support reduced healthcare cost per person per year from outpatient visits and medication (medians $148 and $3, respectively; median follow-up, 12-13 months). SMBP within TBC exhibited an increase in healthcare cost (median, $369 per person per year; median follow-up, 18 months). SMBP alone varied from cost saving to a maximum cost of $144,000 per QALY saved, with two studies reporting an increase in SBP. The two translated median costs per QALY saved were $2,800 and $4,000 for SMBP with additional support and $7,500 and $10,800 for SMBP within TBC. CONCLUSIONS SMBP monitoring interventions with additional support or within TBC are cost effective. Cost effectiveness of SMBP used alone could not be determined.

Abstract
Structured lifestyle interventions can reduce diabetes incidence and cardiovascular disease (CVD) risk among persons with impaired glucose tolerance (IGT), but it is unclear whether they should be implemented among persons without IGT. We conducted a systematic review and meta-analyses to assess the effectiveness of lifestyle interventions on CVD risk among adults without IGT or diabetes. We systematically searched MEDLINE, EMBASE, CINAHL, Web of Science, the Cochrane Library, and PsychInfo databases, from inception to May 4, 2016. We selected randomized controlled trials of lifestyle interventions, involving physical activity (PA), dietary (D), or combined strategies (PA+D) with follow-up duration ≥12 months. We excluded all studies that included individuals with IGT, confirmed by 2-hours oral glucose tolerance test (75g), but included all other studies recruiting populations with different glycemic levels. We stratified studies by baseline glycemic levels: (1) low-range group with mean fasting plasma glucose (FPG) <5.5mmol/L or glycated hemoglobin (A1C) <5.5%, and (2) high-range group with FPG ≥5.5mmol/L or A1C ≥5.5%, and synthesized data using random-effects models. Primary outcomes in this review included systolic blood pressure (SBP), diastolic blood pressure (DBP), total cholesterol (TC), low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C), and triglycerides (TG). Totally 79 studies met inclusion criteria. Compared to usual care (UC), lifestyle interventions achieved significant improvements in SBP (-2.16mmHg[95%CI, -2.93, -1.39]), DBP (-1.83mmHg[-2.34, -1.31]), TC (-0.10mmol/L[-0.15, -0.05]), LDL-C (-0.09mmol/L[-0.13, -0.04]), HDL-C (0.03mmol/L[0.01, 0.04]), and TG (-0.08mmol/L[-0.14, -0.03]). Similar effects were observed among both low-and high-range study groups except for TC and TG. Similar effects also appeared in SBP and DBP categories regardless of follow-up duration. PA+D interventions had larger improvement effects on CVD risk factors than PA alone interventions. In adults without IGT or diabetes, lifestyle interventions resulted in significant improvements in SBP, DBP, TC, LDL-C, HDL-C, and TG, and might further reduce CVD risk.

Abstract
Members of the heterotrimeric guanine nucleotide-binding protein (G protein)-coupled receptor (GPCR) family play key roles in many physiological functions and are extensively exploited pharmacologically to treat diseases. Many of the diverse effects of individual GPCRs on cellular physiology are transduced by heterotrimeric G proteins, which are composed of α, β, and γ subunits. GPCRs interact with and stimulate the binding of guanosine triphosphate (GTP) to the α subunit to initiate signaling. Mammalian genomes encode 16 different G protein α subunits, each one of which has distinct properties. We developed a single-platform, optical strategy to monitor G protein activation in live cells. With this system, we profiled the coupling ability of individual GPCRs for different α subunits, simultaneously quantifying the magnitude of the signal and the rates at which the receptors activated the G proteins. We found that individual receptors engaged multiple G proteins with varying efficacy and kinetics, generating fingerprint-like profiles. Different classes of GPCR ligands, including full and partial agonists, allosteric modulators, and antagonists, distinctly affected these fingerprints to functionally bias GPCR signaling. Finally, we showed that intracellular signaling modulators further altered the G protein-coupling profiles of GPCRs, which suggests that their differential abundance may alter signaling outcomes in a cell-specific manner. These observations suggest that the diversity of the effects of GPCRs on cellular physiology may be determined by their differential engagement of multiple G proteins, coupling to which produces signals with varying signal magnitudes and activation kinetics, properties that may be exploited pharmacologically.

Abstract
To limit global warming to <2 °C we must reduce the net amount of CO2 we release into the atmosphere, either by producing less CO2 (conventional mitigation) or by capturing more CO2 (negative emissions). Here, using state-of-the-art carbon-climate models, we quantify the trade-off between these two options in RCP2.6: an Intergovernmental Panel on Climate Change scenario likely to limit global warming below 2 °C. In our best-case illustrative assumption of conventional mitigation, negative emissions of 0.5-3 Gt C (gigatonnes of carbon) per year and storage capacity of 50-250 Gt C are required. In our worst case, those requirements are 7-11 Gt C per year and 1,000-1,600 Gt C, respectively. Because these figures have not been shown to be feasible, we conclude that development of negative emission technologies should be accelerated, but also that conventional mitigation must remain a substantial part of any climate policy aiming at the 2-°C target.

Abstract
We report the incorporation of functionalised carbon nanodots within a low molecular weight salt hydrogel enhancing the gelation and fluorescence properties of both the gel and carbon nanomaterial.
The incorporation of functionalised carbon nanodots within a novel low molecular weight salt hydrogel derived from 5-aminosalicylic acid is reported. The carbon dots result in markedly enhanced gelation properties, while inclusion within the hydrophobic gel results in a dramatic fluorescence enhancement for the carbon nanomaterials. The resulting hybrid CD gels exhibit a useful sensor response for heavy metal ions, particularly Pb2+.

Abstract
Tobacco use is the leading preventable cause of disease and death in the United States, and nearly all tobacco use begins during youth and young adulthood. Among U.S. youths, cigarette smoking has declined in recent years; however, the use of some other tobacco products has increased, and nearly half of tobacco users use two or more tobacco products. CDC analyzed data from the 2013 National Youth Tobacco Survey to determine the prevalence of ever (at least once) and current (at least 1 day in the past 30 days) use of one or more of 10 tobacco products (cigarettes, cigars, hookahs, smokeless tobacco, electronic cigarettes [e-cigarettes], pipes, snus, bidis, kreteks, and dissolvable tobacco) among U.S. middle school (grades 6-8) and high school (grades 9-12) students. In 2013, 22.9% of high school students reported current use of any tobacco product, and 12.6% reported current use of two or more tobacco products; current use of combustible products (i.e., cigarettes, cigars, pipes, bidis, kreteks, and/or hookahs) was substantially greater (20.7%) than use of other types of tobacco. Also, 46.0% of high school students reported having ever tried a tobacco product, and 31.4% reported ever trying two or more tobacco products. Among middle school students, 3.1% reported current use of cigars, and 2.9% reported current use of cigarettes, with non-Hispanic black students more than twice as likely to report current use of cigars than cigarettes. Monitoring the prevalence of the use of all available tobacco products, including new and emerging products, is critical to support effective population-based interventions to prevent and reduce tobacco use among youths as part of comprehensive tobacco prevention and control programs.

Abstract
We report on the statistics of bubble size, topology, and shape and on their role in the coarsening dynamics for foams consisting of bubbles compressed between two parallel plates. The design of the sample cell permits control of the liquid content, through a constant pressure condition set by the height of the foam above a liquid reservoir. We find that in the scaling regime, all bubble distributions are independent not only of time, but also of liquid content. For coarsening, the average rate decreases with liquid content due to the blocking of gas diffusion by Plateau borders inflated with liquid; we achieve a factor of 4 reduction from the dry limit. By observing the growth rate of individual bubbles, we find that von Neumann's law becomes progressively violated with increasing wetness and decreasing bubble size. We successfully model this behavior by explicitly incorporating the border-blocking effect into the von Neumann argument. Two dimensionless bubble shape parameters naturally arise, one of which is primarily responsible for the violation of von Neumann's law for foams that are not perfectly dry.

Abstract
A best evidence topic was written according to a structured protocol, asking 'does surgery improve prognosis in patients with small-cell lung carcinoma (SCLC)?' One hundred and thirteen papers were identified, of which the nine papers best able to answer the question were selected and the details of each tabulated. The prohibitive attitude of clinicians toward surgery in SCLC has prevailed since the 1960s, informed by a prospective randomized trial in which 144 patients were assigned to surgical treatment or to radical radiotherapy. Surgery conferred no survival benefit when compared with radical radiotherapy as assessed at 6 monthly intervals up to 10 years post-treatment. Patients with metastatic disease were excluded; however, diagnostic advances subsequent to these trials justify a re-evaluation of the issue, given the greater degree of accuracy with which sub-groups of patients who might benefit from surgery can now be defined. Only one further prospective, randomized trial features in the literature. This study also discerned that no survival benefit was accrued by adding surgery to chemotherapy. However, this study only included patients who responded to an initial course of chemotherapy and also excluded patients with peripheral nodules only. Subsequent investigators have asserted the value of surgery in SCLC. A retrospective case-control study found that surgery significantly improved median survival in patients with stage I disease when compared with patients undergoing medical therapy. One British centre reported survival rates of 52% at 5 years amongst patients undergoing resection and nodal dissection for stage II-IIIA disease. In a retrospective analysis of the Norwegian cancer database, 5-year survival for patients with stage I undergoing surgery was 44.9%, as opposed to 11.3% amongst those treated medically. This finding was echoed in the analysis of the surveillance epidemiology and end results database in the USA, which found improved median survival amongst patients undergoing surgery for limited SCLC. Prospective studies of carefully selected patients have documented good median survival in patients whose tumour was completely resected. We conclude that surgery for early-stage SCLC improves prognosis as part of a multi-modality approach. This echoes the advice of the 2011 national institute of health and clinical excellence guidelines regarding surgery in SCLC.
