description: The ten-eleven translocation (TET) family (TET1/2/3) initiates conversion of 5-methylcytosine to 5-hydroxymethylcytosine, thereby orchestrating the DNA demethylation process and changes in epigenetic marks during early embryogenesis. In this study, CRISPR/Cas9 technology and a TET-specific inhibitor were applied to elucidate the role of TET family in regulating pluripotency in preimplantation embryos using porcine embryos as a model. Disruption of TET1 unexpectedly resulted in the upregulation of NANOG and ESRRB transcripts, although there was no change to the level of DNA methylation in the promoter of NANOG. Surprisingly, a threefold increase in the transcript level of TET3 was observed in blastocysts carrying modified TET1, which may explain the upregulation of NANOG and ESRRB. When the activity of TET enzymes was inhibited by dimethyloxalylglycine (DMOG) treatment, a dioxygenase inhibitor, to investigate the role of TET1 while eliminating the potential compensatory activation of TET3, reduced level of pluripotency genes including NANOG and ESRRB, and increased level of DNA methylation in the NANOG promoter was detected. Blastocysts treated with DMOG also presented a lower inner cell mass/TE ratio, implying the involvement of TET family in lineage specification in blastocysts. Our results indicate that the TET family modulates proper expression of NANOG, a key pluripotency marker, by controlling its DNA methylation profile in the promoter during embryogenesis. This study suggests that TET family is a critical component in pluripotency network of porcine embryos by regulating gene expression involved in pluripotency and early lineage specification.

description: INTEGRAL has observed the bright quasar 3C 273 on 3 epochs in January 2003 as one of the first observations of the open programme. The observation on January 5 was simultaneous with RXTE and XMM-Newton observations. We present here a first analysis of the continuum emission as observed by these 3 satellites in the band from 3 keV to 500 keV. The continuum spectral energy distribution of 3C 273 was observed to be weak and steep in the high energies during this campaign. We present the actual status of the cross calibrations between the instruments on the three platforms using the calibrations available in June 2003.

(Fig. 33, 34)
 Porphyrogenes glavia Evans, 1952. Type locality: Panama; male [holo] type (Fig. 33, 34), in BM(NH).
 Description. Male (measured and described from photographs of the [holo] type, Fig. 33, 34) - forewing length = 19.6 mm; forewing with no apparent costal fold, apex rounded, termen convex, anal margin slightly convex; hindwing termen convex, tornus produced to very short lobe, vein Rs arising nearer to end of discal cell than to its base and distad of CuA 2; dorsum brown (purplish gloss noted by Evans 1952 not evident in photograph), unmarked; no overscaling evident, no apparent tuft; hindwing with shining grayish brown speculum in proximal 1/3 of costal cell; no tufts evident; fringes on both wings pale brown.
 Venter duller brown than dorsum with purplish wash; forewing veins CuA 1, CuA 2, and 2A strongly bowed, otherwise vein 2A appears unmodified; shining gray-brown speculum in proximal 1/4 of CuA 2 -2A and apparently modified gray-brown scales in proximal 1/2 of anal cell; hindwing with no indication of discal macules; cell 2A-3A with groove proximad just caudad of vein 2A.
 Dorsal head and thorax appearing dark brown, palpi brown with 3rd segment upcurved and extended far beyond 2nd segment (a character not on other Porphyrogenes), eyes red, antennae black on dorsum, whitish on venter and beneath apiculus; ventral thorax apparently brownish, legs missing; abdomen brownish.
Genitalia - not examined. Evans’ (1952) figure indicated a broad valva cephalad with the spiculose caudal end of the harpe very narrow and directed dorsad.
Female - not examined.
 Distribution. The type is from Panama and the associated female has no location indicated (Evans 1952); these are the only known specimens of this species.
 Diagnosis and discussion. The female of P. glavia was described as being brown on the dorsum with a purple flush and a bright ochreous hindwing, yellow-brown on the venter, and without macules on the forewing (Evans 1952); this specimen was not examined for this study. This species was named from a pair of specimens; the male in the BM(NH) is the [holo] type (Fig. 33, 34). Porphyrogenes glavia cannot be confused with any other species of Porphyrogenes.

description: Wildfires are an important ecological threat in Côte d’Ivoire with the northern half the most affected zone. This study assessed farmers’ perception of wildfire occurrence in the N’Zi River Watershed and compared this perception to remotely sensed fire data trends. To this end, 259 farmers were individually interviewed and 18 farmers were involved in three focus group discussions in three agro-ecological zones. A combination of descriptive statistics and regression analysis was used for data analysis. Results showed that 78.75% of farmers observed the upward trend in the annual wildfire activity identified by remote sensing data during 2001–2016. Most of the respondents identified hunting (65.83%), farm establishment (50%) and firebreaks establishment (46.67%) as main causes of wildfires. The perceived impacts of wildfires included immediate crop burning, crop growth delaying, mid-term post-fire crop destruction, destruction of material goods and loss of human life. Local population developed endogenous strategies to cope with this scourge. Amongst identified coping strategies, firebreaks establishment and maintenance around new clearings and farms and prohibition of fire-hunting during the dry season were highlighted. Therefore, policies and institutions that support local wildfires management initiatives must take advantage of the strong community knowledge and networks to strengthen their effectiveness and sustainability.

description: The Sun's corona has interested researchers for multiple reasons, including the search for solution for the famous coronal heating problem and a purely practical consideration of predicting geomagnetic storms on Earth. There exist numerous different theories regarding the solar corona; therefore, it is important to be able to perform comparative analysis and validation of those theories. One way that could help us move towards the answers to those problems is the search for observational methods that could obtain information about the physical properties of the solar corona and provide means for comparing different solar corona models. In this work we present evidence that VLBI observations are, in certain conditions, sensitive to the electron density of the solar corona and are able to distinguish between different electron density models, which makes the technique of VLBI valuable for solar corona investigations. Recent works on the subject used a symmetric power-law model of the electron density in solar plasma; in this work, an improvement is proposed based on a 3D numerical model.

description: Distinct observations are those different with respect to one or more variables, considered either individually or jointly. Distinctness is thus a key aspect of the similarity or difference of observations. It is sometimes confounded with uniqueness. Counting the number of distinct observations may be required at any point from initial data cleaning or checking to subsequent statistical analysis. We review how far existing commands in official Stata offer solutions to this issue, and we show how to answer questions about distinct observations from first principles by using the by prefix and the egen command. The new distinct command is offered as a convenience tool.

description: Clinical and experimental evidences indicate that epigenetic modifications induced by the prenatal environment are related to metabolic and reproductive derangements in polycystic ovary syndrome (PCOS). Alterations in the leptin and adiponectin systems, androgen signalling and antimüllerian hormone (AMH) levels have been observed in PCOS women and in their offspring. Using a targeted Next-Generation Sequencing (NGS), we studied DNA methylation in promoter regions of the leptin (LEP), leptin receptor (LEPR), adiponectin (ADIPOQ), adiponectin receptor 1 and 2 (ADIPOR1 and ADIPOR2), AMH and androgen receptor (AR) genes in 24 sons and daughters of women with PCOS (12 treated with metformin during pregnancy) and 24 children born to non-PCOS women during early infancy (2–3 months of age). Genomic DNA was extracted from whole blood, bisulphite converted and sequenced by NGS. Girls showed differences between groups in 1 CpG site of LEPR, 2 of LEP, 1 of ADIPOR2 and 2 of AR. Boys showed differences in 5 CpG sites of LEP, 3 of AMH and 9 of AR. Maternal metformin treatment prevented some of these changes in LEP, ADIPOR2 and partially in AR in girls, and in LEP and AMH in boys. Maternal BMI at early pregnancy was inversely correlated with the methylation levels of the ChrX-67544981 site in the whole group of girls (r = −0.530, p = 0.008) and with the global Z-score in all boys (r = −0.539, p = 0.007). These data indicate that the intrauterine PCOS environment predisposes the offspring to acquire certain sex-dependent DNA methylation patterns in the promoter regions of metabolic and reproductive genes.
3.1 $μ$m H$_{2}$O Ice Absorption in LINER-Type Ultraluminous Infrared Galaxies with Cool Far-Infrared Colors: the Centrally-Concentrated Nature of Their Deeply Buried Energy Sources

description: Ground-based 2.8--4.1 $μ$m slit spectra of the nuclei of seven ultraluminous infrared galaxies (ULIRGs) that are classified optically as LINERs and have cool far-infrared colors are presented. All the nuclei show 3.3 $μ$m polycyclic aromatic hydrocarbon (PAH) emission, with equivalent widths that are systematically lower than those in starburst galaxies. Strong 3.1 $μ$m H$_{2}$O ice absorption, with optical depth greater than 0.6, is also detected in five nuclei, and 3.4 $μ$m carbonaceous dust absorption is detected clearly in one of the five nuclei. It is quantitatively demonstrated that the large optical depths of the H$_{2}$O ice absorption in the five sources, and the 3.4 $μ$m absorption in one source, are incompatible with a geometry in which the energy sources are spatially mixed with dust and molecular gas, as is expected for a typical starburst, but instead require that a large amount of nuclear dust (including ice-covered grains) and molecular gas be distributed in a screen in front of the 3--4 $μ$m continuum-emitting sources. This geometrical requirement can naturally be met if the energy sources are more centrally concentrated than the nuclear dust and molecular gas. The low equivalent widths of the PAH emission compared to starbursts and the central concentration of the nuclear energy sources in these five ULIRGs are best explained by the presence of energetically important active galactic nuclei deeply buried in dust and molecular gas.

description: We determine several quantities in quenched lattice QCD with exact chiral symmetry. For 100 gauge configurations generated with Wilson gauge action at $ β= 6.0 $ on the $ 16^3 \times 32 $ lattice, we compute quenched quark propagators for 13 bare quark masses. The pion decay constant is extracted from the pion propagator, and from which the inverse lattice spacing is determined to be $ a^{-1} = 1.979(6) $ GeV. The parameters ($ C, δ, B $) in the pseudoscalar meson mass formula in quenched chiral perturbation theory (q$χ$PT) to one-loop order are determined. Further, we measure the index (topological) susceptibility of these 100 gauge configurations, $ χ_t = (175 \pm 6 {MeV})^4 $, from which we obtain an estimate of the mass of $ η' $ in q$χ$PT, and the coefficient of quenched chiral logarithm, both in good agreement with the values determined from the pion masses, as well as with the theoretical estimates. With our values of $ C, δ, B $, the experimental inputs of pion and kaon masses, and the pion decay constant, we determine the light quark masses: $ m_{u,d} = 4.1 \pm 0.3 $ MeV, and $ m_s = 92 \pm 9 $ MeV, in the $ \bar{MS} $ scheme at scale $ μ= 2 $ GeV. Also, we determine the quark condensate $ = -(250 \pm 3 {MeV})^3 $, and the quark-gluon condensate $ g < \bar q σ_{μν} F_{μν} q > = -(434 \pm 4 {MeV})^5 $, in the $ \bar{MS} $ scheme at scale 2 GeV.

description: A unified approach to derive optimal finite differences is presented which combines three critical elements for numerical performance especially for multi-scale physical problems, namely, order of accuracy, spectral resolution and stability. The resulting mathematical framework reduces to a minimization problem subjected to equality and inequality constraints. We show that the framework can provide analytical results for optimal schemes and their numerical performance including, for example, the type of errors that appear for spectrally optimal schemes. By coupling the problem in this unified framework, one can effectively decouple the requirements for order of accuracy and spectral resolution, for example. Alternatively, we show how the framework exposes the tradeoffs between e.g. accuracy and stability and how this can be used to construct explicit schemes that remain stable with very large time steps. We also show how spectrally optimal schemes only bias odd-order derivatives to remain stable, at the expense of accuracy, while leaving even-order derivatives with symmetric coefficients. Schemes constructed within this framework are tested for diverse model problems with an emphasis on reproducing the physics accurately.

description: International aid and funding agencies usually receive more requests to support conservation proposals than can be supported by their available funds and therefore have to rank these. A checklist of questions or factors which may be taken into account by funding agencies in prioritising inter-country and inter-regional requests is given. The mechanics of allocation of funds on the basis of net economic benefits are discussed and limitations of the cost benefit approach are noted. A list of factors likely to•favour the selection of particular projects is listed. Communicators should take those into account. The possibility of non-economic and strategic factors influencing the distribution of funds for support of protected areas is discussed.

description: The electronic and magnetic properties of clinopyroxene CaMnGe$_2$O$_6$ were studied using density function calculations within the GGA+U approximation. It is shown that anomalous ferromagnetic ordering of neighboring chains is due to a "common-enemy" mechanism. Two antiferromagnetic exchange couplings between nearest neighbours within the Mn-Mn chain and interchain coupling via two GeO$_4$ tetrahedra suppress antiferromagnetic exchange via single GeO$_4$ tetrahedron and stabilize ferromagnetic ordering of Mn chains.

description: With the ravages of deforestation, Aframomum melegueta (grains of paradise) is gradually getting extinct, despite its potential for consumption and trade. This study sought to find out land uses in off-reserve tree farms capable of providing the optimum conditions for the production of grains of paradise. The Completely Randomized Design (CRD) with three replications was used to lay the plots and the treatments examined were cocoa, oil palm, and fallow land uses. Also, the ethnobotanical knowledge of farmers was studied by purposively sampling a total of 30 Aframomum melegueta farmers. The results showed no significant (P > .05) difference for the number of pods, fresh weight, and yield of Aframomum melegueta per hectare among the different land uses. On the other hand, the average pod length significantly differed (P Aframomum melegueta for the treatment of stroke. Gender and education of farmers did not play a significant role in sources of collection and land use preference of Aframomum melegueta respectively. The major challenge confronting the cultivation of Aframomum melegueta was the lack of an external market (33.3%). The majority of farmers preferred fallow land (73.9%) for the cultivation of Aframomum melegueta. The cultivation of Aframomum melegueta in off-reserve tree farms could help increase the quantity produced and thus improve the livelihood of farmers. Farmers are encouraged to plant the species on their cocoa farms, oil palm farms, and fallow lands.

description: Two sets of MgB2 samples doped with up to 5 at. % of Al were prepared in different laboratories using different procedures. Decreases in the a and c lattice parameters were observed with Al doping confirming Al substitution onto the Mg site. The critical temperature (Tc) remained largely unchanged with Al doping. For 1 - 2.5 at.% doping, at 20K the in-field critical current densities (Jc's) were enhanced, particularly at lower fields. At 5K, in-field Jc was markedly improved, e.g. at 5T Jc was enhanced by a factor of 20 for a doping level of 1 at.% Al. The improved Jcs correlate with increased sample resistivity indicative of an increase in the upper critical field, Hc2, through alloying.

description: Loggers play critical roles in forest management and resource production, yet supply chain pressures can challenge their economic sustainability. We examine logger perspectives on efficiency, financial challenges, and potential solutions from two contrasting perspectives: 1) business strategy and 2) treadmill of production, a sociological critique of resource production that links economic and ecological sustainability. To provide in-depth perspectives based on lived experiences, we conducted interviews with professional loggers and other stakeholders, focusing on firms with mechanized cut-to-length systems in Wisconsin and Michigan’s Upper Peninsula. Our qualitative analysis revealed the intersection of factors that help explain financial stress. Loggers work on contract or buy stumpage from landowners and then sell to mills. Perceived challenges included competition in stumpage markets, relationships to mills that disadvantaged small firms, debt from mechanization, and site access through variable environmental conditions. Loggers worked to increase efficiency and production volume, though some loggers expressed the limits of increasing efficiency and production for improving profitability. Proposed solutions to reduce financial stress included long-term mill contracts, access to loans, and improved financial literacy. Nonetheless, individual firm efficiency will not address structural challenges such as loggers’ role in the supply chain between landowners and mills.

description: Chronic kidney disease (CKD) related cardiovascular disease (CVD) is characterized by vascular remodelling with well-established structural and functional changes in the vascular wall such as arterial stiffness, matrix deposition, and calcification. These phenotypic changes resemble pathology seen in ageing, and are likely to be mediated by sustained alterations in gene expression, which may be caused by epigenetic changes such as tissue-specific DNA methylation. We aimed to investigate tissue specific changes in DNA methylation that occur in CKD-related CVD. Genome-wide DNA methylation changes were examined in bisulphite converted genomic DNA isolated from the vascular media of CKD and healthy arteries. Methylation-specific PCR was used to validate the array data, and the association between DNA methylation and gene and protein expression was examined. The DNA methylation age was compared to the chronological age in both cases and controls. Three hundred and nineteen differentially methylated regions (DMR) were identified spread across the genome. Pathway analysis revealed that DMRs associated with genes were involved in embryonic and vascular development, and signalling pathways such as TGFβ and FGF. Expression of top differentially methylated gene HOXA5 showed a significant negative correlation with DNA methylation. Interestingly, DNA methylation age and chronological age were highly correlated, but there was no evidence of accelerated age-related DNA methylation in the arteries of CKD patients. In conclusion, we demonstrated that differential DNA methylation in the arterial tissue of CKD patients represents a potential mediator of arterial pathology and may be used to uncover novel pathways in the genesis of CKD-associated complications.

 Diagnosis and discussion. Porphyrogenes stupa was described from a single male without data in the BM (NH) (Evans 1952), the [holo] type (Fig. 41, 42). Its combination of very dark color, pattern of venation, and the harpe bending and then expanding caudad are distinctive and should facilitate the identification of other specimens of the species.

description: We study the entanglement of the superconducting charge qubit with the quantized electromagnetic field in a microwave cavity. It can be controlled dynamically by a classical external field threading the SQUID within the charge qubit. Utilizing the controllable quantum entanglement, we can demonstrate the dynamic process of the quantum storage of information carried by charge qubit. On the other hand, based on this engineered quantum entanglement, we can also demonstrate a progressive decoherence of charge qubit with quantum jump due to the coupling with the cavity field in quasi-classical state.

description: Strongly lensed quasars with time-delay measurements are well known to provide the "time-delay distances" $D_{Δt}=(1+z_L)D_LD_S/D_{LS}$ and the angular diameter distances to lens galaxies $D_L$. These two kinds of distances give stringent constraints on cosmological parameters. In this work, we explore a different use of time-delay observables: Under the assumption of a flat Universe, strong lensing observations can accurately measure the angular diameter distances to sources $D_S$. The corresponding redshifts of quasars may be up to $z_S\sim4$ according to the forecast. The high-redshift distances would sample the Hubble diagram between SNe Ia and CMB, cosmological-model-independently providing direct information on the evolution of the nature of our Universe, for example, the dark energy Equation-of-State parameter $w(z)$. We apply our method to the existing lensing system SDSS 1206+4332 and get $D_S=2388_{-978}^{+2632}Mpc$ at $z_S=1.789$. We also make a forecast for the era of LSST. The uncertainty of $D_S$ depends on the redshifts of lens and source, the uncertainties of $D_{Δt}$ and $D_L$, and the correlation between $D_{Δt}$ and $D_L$ as well. Larger correlation would result in tighter $D_S$ determination.

description: We study the effect of alleviating information asymmetry regarding product quality that is widespread in developing-country agricultural markets. Opportunistic buyers may underreport quality levels back to farmers to reduce the price they have to pay. In response, farmers may curb investment, negatively affecting farm productivity. In an experiment, we entitle randomly selected smallholder dairy farmers in Vietnam to independently verify milk testing results. Treatment farmers use 13 percent more inputs and also increase their output. We show that the buying company had initially not underreported product quality, which is why third-party monitoring led to a Pareto improvement in the supply chain.

description: We present an analysis of Hubble Space Telescope/WFPC2 images of nine nearby galaxies in Sculptor. We derive their distances from the luminosity of the tip of the red giant branch stars with a typical accuracy of ~ 12%. Their distances are 4.21 Mpc (Sc22), 4.92 Mpc (DDO226), 3.94 Mpc (NGC253), 3.40 Mpc (KDG2), 3.34 Mpc (DDO6), 3.42 Mpc (ESO540-030), 4.43 Mpc (ESO245-05), 4.27 Mpc (UGCA442), and 3.91 Mpc (NGC7793). The galaxies are concentrated in several spatially separated loose groups around NGC300, NGC253, and NGC7793. The Sculptor galaxy complex together with the CVn I cloud and the Local Group form a 10 Mpc amorphous filament, apparently driven by the free Hubble flow.

Models for Solar Abundance Stars with Gravitational Settling and Radiative Accelerations: Application to M67 and NGC188

description: Evolutionary models taking into account radiative accelerations, thermal diffusion, and gravitational settling for 28 elements, including all those contributing to OPAL stellar opacities, have been calculated for solar metallicity stars of 0.5 to 1.4 solar masses. The Sun has been used to calibrate the models. Isochrones are fitted to the observed color-magnitude diagrams (CMDs) of M67 and NGC188, and ages of 3.7 and 6.4 Gyr are respectively determined. Convective core overshooting is not required to match the turnoff morphology of either cluster, including the luminosity of the gap in M67, because central convective cores are larger when diffusive processes are treated. This is due mainly to the enhanced helium and metal abundances in the central regions of such models. The observation of solar metallicity open clusters with ages in the range 4.8--5.7Gyr would further test the calculations of atomic diffusion in central stellar regions: according to non-diffusive isochrones, clusters should not have gaps near their main-sequence turnoffs if they are older than ~4.8Gyr, whereas diffusive isochrones predict that gaps should persist up to ages of ~5.7Gyr. Surface abundance isochrones are also calculated. In the case of M67 and NGC188, surface abundance variations are expected to be small. Abundance differences between stars of very similar Teff are expected close to the turnoff, especially for elements between P and Ca. Moreover, in comparison with the results obtained for giants, small generalized underabundances are expected in main-sequence stars. The lithium to beryllium ratio is discussed briefly and compared to observations.

Productivity Analysis

description: Self-appraisal--serious self-appraisal--is often recommended, rarely practiced. But the following article is a serious effort to set down and appraise the process or methods by which the Bureau of Agricultural Economics does develop its appraisal of the general economic situation which plays so important a part in our commodity, price, and agricultural outlook work. This statement was first prepared by James P. Cavin, formerly Head of the Division of Statistical and Historical Research, in the form of a paper which was presented at the annual meeting of the American Statistical Association in New York City on December 29, 1949. Since that time the original statement has been subjected to review by a considerable number of persons both within and without the Bureau of Agricultural Economics, and the current article is a revision, prepared by Mr. Cavin in collaboration with Nathan Koffsky, which also brings the analysis through 1951.

description: We compute charm and bottom quark masses in the quenched approximation and in the continuum limit of lattice QCD. We make use of a step scaling method, previously introduced to deal with two scale problems, that allows to take the continuum limit of the lattice data. We determine the RGI quark masses and make the connection to the MSbar scheme. The continuum extrapolation gives us a value m_b^{RGI} = 6.73(16) GeV for the b-quark and m_c^{RGI} = 1.681(36) GeV for the c-quark, corresponding respectively to m_b^{MSbar}(m_b^{MSbar}) = 4.33(10) GeV and m_c^{MSbar}(m_c^{MSbar}) = 1.319(28) GeV. The latter result, in agreement with current estimates, is for us a check of the method. Using our results on the heavy quark masses we compute the mass of the Bc meson, M_{Bc} = 6.46(15) GeV.

description: We present an analytical and phenomenological model for metal enrichment in halos based on hierarchical structure formation. This model assumes that astration of normal stellar populations along with SNe II already occurs at very high redshift. For halos that are not disrupted by SN II explosions, the chemical evolution of the gas and stars is explicitly determined by the rate of gas infall as compared with the astration rate and the corresponding rate of metal production by SNe II per H atom in the gas. This model provides a good description of the data on [Fe/H] for damped Ly alpha systems over a wide range of redshift 0.5 < z < 5. For all halos not disrupted by SN II explosions, if there is a cessation of gas infall, the metallicities of stars follow a bimodal distribution. This distribution is characterized by a sharp peak at the value of [Fe/H] corresponding to the time of infall cessation and by a broad peak at a higher value of [Fe/H] corresponding to the subsequent period of astration during which the bulk of the remaining gas forms stars. Such a distribution may be compared to that observed for the Galactic halo stars. If the gas in a halo is rapidly lost upon cessation of infall, then an assemblage of stars with a very sharply-defined [Fe/H] value will be left behind. This assemblage of stars may be accreted by a larger system and become a globular cluster of the larger system. We also discuss the masses and metallicities of the globular clusters in this model.

description: The Developmental Origins of Health and Disease (DOHaD) theory predicts that prenatal and early life events shape adult health outcomes. Birth weight is a useful indicator of the foetal experience and has been associated with multiple adult health outcomes. DNA methylation (DNAm) is one plausible mechanism behind the relationship of birth weight to adult health. Through data linkage between Generation Scotland and historic Scottish birth cohorts, and birth records held through the NHS Information and Statistics Division, a sample of 1,757 individuals with available birth weight and DNAm data was derived. Epigenome-wide association studies (EWAS) were performed in two independently generated DNAm subgroups (nSet1 = 1,395, nSet2 = 362), relating adult DNAm from whole blood to birth weight. Meta-analysis yielded one genome-wide significant CpG site (p = 5.97x10−9), cg00966482. There was minimal evidence for attenuation of the effect sizes for the lead loci upon adjustment for numerous potential confounder variables (body mass index, educational attainment, and socioeconomic status). Associations between birth weight and epigenetic measures of biological age were also assessed. Associations between lower birth weight and higher Grim Age acceleration (p(FDR) = 3.6x10−3) and shorter DNAm-derived telomere length (p(FDR) = 1.7x10−3) are described, although results for three other epigenetic clocks were null. Our results provide support for an association between birth weight and DNAm both locally at one CpG site, and globally via biological ageing estimates.
