description: Sec14 is the major phosphatidylinositol (PtdIns)/phosphatidylcholine (PtdCho) transfer protein in the yeast Saccharomyces cerevisiae and is the founding member of the Sec14 protein superfamily. Recent functional data suggest that Sec14 functions as a nanoreactor for PtdCho-regulated presentation of PtdIns to PtdIns kinase to affect membrane trafficking. Extrapolation of this concept to other members of the Sec14 superfamily suggests a mechanism by which a comprehensive cohort of Sec14-like nanoreactors sense correspondingly diverse pools of lipid metabolites. In turn, metabolic information is translated to signaling circuits driven by phosphoinositide metabolism. Sfh3, one of five Sec14 homologs in yeast, exhibits several interesting functional features, including its unique localization to lipid particles and microsomes. This localization forecasts novel regulatory interfaces between neutral lipid metabolism and phosphoinositide signaling. To launch a detailed structural and functional characterization of Sfh3, the recombinant protein was purified to homogeneity, diffraction-quality crystals were produced and a native X-ray data set was collected to 2.2 Å resolution. To aid in phasing, SAD X-ray diffraction data were collected to 1.93 Å resolution from an SeMet-labeled crystal at the Southeast Regional Collaborative Access Team at the Advanced Photon Source. Here, the cloning and purification of Sfh3 and the preliminary diffraction of Sfh3 crystals are reported, enabling structural analyses that are expected to reveal novel principles governing ligand binding and functional specificity for Sec14-superfamily proteins.

description: Direct numerical simulations of a liquid metal filling the gap between two concentric spheres are presented. The flow is governed by the interplay between the rotation of the inner sphere (measured by the Reynolds number Re) and a weak externally applied axial magnetic field (measured by the Hartmann number Ha). By varying the latter a rich variety of flow features, both in terms of spatial symmetry and temporal dependence, is obtained. Flows with two or three independent frequencies describing their time evolution are found as a result of Hopf bifurcations. They are stable on a sufficiently large interval of Hartmann numbers where regions of multistability of two, three and even four types of these different flows are detected. The temporal character of the solutions is analysed by means of an accurate frequency analysis and Poincaré sections. An unstable branch of flows undergoing a period doubling cascade and frequency locking of three-frequency solutions is described as well.

description: Identification and characterization of the genetic variants underlying type 2 diabetes susceptibility can provide important understanding of the etiology and pathogenesis of type 2 diabetes. We previously identified strong evidence of linkage for type 2 diabetes on chromosome 22 among 3,383 Hypertension Genetic Epidemiology Network (HyperGEN) participants from 1,124 families. The checkpoint 2 (CHEK2) gene, an important mediator of cellular responses to DNA damage, is located 0.22 Mb from this linkage peak. In this study, we tested the hypothesis that the CHEK2 gene contains one or more polymorphic variants that are associated with type 2 diabetes in HyperGEN individuals. In addition, we replicated our findings in two other Family Blood Pressure Program (FBPP) populations and in the population-based Atherosclerosis Risk in Communities (ARIC) study. We genotyped 1,584 African-American and 1,531 white HyperGEN participants, 1,843 African-American and 1,569 white GENOA participants, 871 African-American and 1,009 white GenNet participants, and 4,266 African-American and 11,478 white ARIC participants for four single nucleotide polymorphisms (SNPs) in CHEK2. Using additive models, we evaluated the association of CHEK2 SNPs with type 2 diabetes in participants within each study population stratified by race, and in a meta-analysis, adjusting for age, age2, sex, sex-by-age interaction, study center, and relatedness. One CHEK2 variant, rs4035540, was associated with an increased risk of type 2 diabetes in HyperGEN participants, two replication samples, and in the meta-analysis. These results may suggest a new pathway in the pathogenesis of type 2 diabetes that involves pancreatic beta-cell damage and apoptosis.

description: The prevalence of cardiovascular disease (CVD) risk factors among youth with type 1 diabetes is high and associated with age, gender, and race/ethnicity. It has also been shown that youth with type 1 diabetes often do not follow dietary recommendations. The objective of this cross-sectional observational study was to explore the association of sugar-sweetened and diet beverage intake with A1c, plasma lipids, adiponectin, leptin, systolic, and diastolic blood pressure in youth with type 1 diabetes. We examined data from 1,806 youth age 10–22 years with type 1 diabetes, of which 22% were minority (10% Hispanic, 8% African Americans, 4% other races) and 48% were female. Sugar-sweetened beverage, diet beverage, and mineral water intake was assessed with a food frequency questionnaire. After adjustment for socio-demographic and clinical covariates, physical activity and total energy intake, high sugar-sweetened beverage intake (at least one serving per day vs. none), was associated with higher levels of total cholesterol, LDL cholesterol, and plasma triglycerides, but not with A1c. High diet beverage intake was associated with higher A1c, total cholesterol, LDL cholesterol, and triglycerides. These associations were partially confounded by body mass index, saturated fat and total fiber intake. High sugar-sweetened beverage intake may have an adverse effect on CVD risk in youth with type 1 diabetes. Diet beverage intake may be a marker of unhealthy lifestyle which, in turn, is associated with worse metabolic control and CVD risk profile in these youth. Youth with diabetes should be encouraged to minimize sugar-sweetened beverage intake.

description: Activating mutations in the gene encoding β-catenin have been identified in the paediatric form of human craniopharyngioma (adamantinomatous craniopharyngioma, ACP), a histologically benign but aggressive pituitary tumour accounting for up to 10% of paediatric intracranial tumours. Recently, we generated an ACP mouse model and revealed that, as in human ACP, nucleocytoplasmic accumulation of β-catenin (β-catnc) and over-activation of the Wnt/β-catenin pathway occurs only in a very small proportion of cells, which form clusters. Here, combining mouse genetics, fluorescence labelling and flow-sorting techniques, we have isolated these cells from tumorigenic mouse pituitaries and shown that the β-catnc cells are enriched for colony-forming cells when cultured in stem cell-promoting media, and have longer telomeres, indicating shared properties with normal pituitary progenitors/stem cells (PSCs). Global gene profiling analysis has revealed that these β-catnc cells express high levels of secreted mitogenic signals, such as members of the SHH, BMP and FGF family, in addition to several chemokines and their receptors, suggesting an important autocrine/paracrine role of these cells in the pathogenesis of ACP and a reciprocal communication with their environment. Finally, we highlight the clinical relevance of these findings by showing that these pathways are also up-regulated in the β-catnc cell clusters identified in human ACP. As well as providing further support to the concept that pituitary stem cells may play an important role in the oncogenesis of human ACP, our data reveal novel disease biomarkers and potential pharmacological targets for the treatment of these devastating childhood tumours.Electronic supplementary materialThe online version of this article (doi:10.1007/s00401-012-0957-9) contains supplementary material, which is available to authorized users.

description: We present the results of a new, non-parametric method to reconstruct the Galactic dark matter profile directly from observations. Using the latest kinematic data to track the total gravitational potential and the observed distribution of stars and gas to set the baryonic component, we infer the dark matter contribution to the circular velocity across the Galaxy. The radial derivative of this dynamical contribution is then estimated to extract the dark matter profile. The innovative feature of our approach is that it makes no assumption on the functional form nor shape of the profile, thus allowing for a clean determination with no theoretical bias. We illustrate the power of the method by constraining the spherical dark matter profile between 2.5 and 25 kpc away from the Galactic centre. The results show that the proposed method, free of widely used assumptions, can already be applied to pinpoint the dark matter distribution in the Milky Way with competitive accuracy, and paves the way for future developments.

description: We explored sex ratio at birth, defined as the proportion of male live births, in women with anorexia nervosa, bulimia nervosa, binge eating disorder, and eating disorders not otherwise specified-purging type (EDNOS-P) relative to a referent group in a large population based sample of 38,340 pregnant women in Norway. Poisson regressions were adjusted for mother’s age, pre-pregnancy BMI, lifetime smoking status, maternal education, income, marital status, gestational age, and parity. Lower proportions of male live births were observed in the anorexia and bulimia groups, while binge eating disorder and EDNOS-P were associated with a higher proportion of male births. These data suggest that maternal eating disorders may influence offspring sex and that the direction of effect may vary by eating disorder subtype. If confirmed, this finding could provide evidence in formulating hypotheses regarding the consequences of eating disorders and determinants of sex ratio at birth.

description: Abstract Objective. To determine if pregnancy complications are increased in super-obese (a body mass index (BMI) of 50 or more) compared to other, less obese parturients. Design. Cross-sectional study. Setting and population. All 19,700 eligible women, including 425 (2.2%) super-obese women with singleton births between 1996 and 2007 delivering at a tertiary referral center, identified using a perinatal research database. Methods. Bivariate and trend analyses were used to assess the relation between super-obesity and various pregnancy complications compared to other well-established BMI categories. Adjusted odds ratios (ORs) were calculated using multivariable logistic regression techniques. Main outcome measures. Outcomes for adjusted and unadjusted analyses were small-for-gestational age (SGA) birth, large-for-gestational age (LGA) birth, preeclampsia, gestational diabetes mellitus (GDM), fetal death, preterm birth, placental abruption, cesarean delivery, and Apgar scores < 7. Results. Compared to all other obese and non-obese women, super-obese women had the highest rates of preeclampsia, GDM, LGA, and cesarean delivery (all p < 0.05 for trend test). Super-obesity was also associated with a 44% reduction in SGA compared to all other women (OR 0.55, 95% confidence interval (CI) 0.40–0.76) and a 25% reduction compared to other, less obese women (OR 0.75, 95% CI 0.54–1.03). Super-obesity was positively associated with LGA, GDM, preeclampsia, cesarean delivery, and a 5-minute Apgar score < 7 compared to all other women after controlling for important confounders. Conclusion. Super-obesity is associated with higher rates of pregnancy complications compared to women of all other BMI classes, including other obese women.

description: The P2Y14 receptor is a relatively broadly expressed G protein-coupled receptor that is prominently associated with immune and inflammatory cells as well as with many epithelia. This receptor historically was thought to be activated selectively by UDP-glucose and other UDP-sugars. However, UDP is also a very potent agonist of this receptor, and may prove to be one of its most important cognate activators.

description: It is becoming increasingly popular to produce high-resolution maps of vaccination coverage by fitting Bayesian geostatistical models to data from household surveys. Often, the surveys adopt a stratified cluster sampling design. We discuss a number of crucial choices with respect to two key aspects of the map production process: the acknowledgment of the survey design in modeling, and the appropriate presentation of estimates and their uncertainties. Specifically, we consider the importance of accounting for survey stratification and cluster-level non-spatial excess variation in survey outcomes when fitting geostatistical models. We also discuss the trade-off between the geographical scale and precision of model-based estimates, and demonstrate visualization methods for mapping and ranking that emphasize the probabilistic interpretation of results. A novel approach to coverage map presentation is proposed to allow comparison and control of the overall map uncertainty level. We use measles vaccination coverage in Nigeria as a motivating example and illustrate the different issues using data from the 2018 Nigeria Demographic and Health Survey.

description: Multilingualism is common offline, but we have a more limited understanding of the ways multilingualism is displayed online and the roles that multilinguals play in the spread of content between speakers of different languages. We take a computational approach to studying multilingualism using one of the largest user-generated content platforms, Wikipedia. We study multilingualism by collecting and analyzing a large dataset of the content written by multilingual editors of the English, German, and Spanish editions of Wikipedia. This dataset contains over two million paragraphs edited by over 15,000 multilingual users from July 8 to August 9, 2013. We analyze these multilingual editors in terms of their engagement, interests, and language proficiency in their primary and non-primary (secondary) languages and find that the English edition of Wikipedia displays different dynamics from the Spanish and German editions. Users primarily editing the Spanish and German editions make more complex edits than users who edit these editions as a second language. In contrast, users editing the English edition as a second language make edits that are just as complex as the edits by users who primarily edit the English edition. In this way, English serves a special role bringing together content written by multilinguals from many language editions. Nonetheless, language remains a formidable hurdle to the spread of content: we find evidence for a complexity barrier whereby editors are less likely to edit complex content in a second language. In addition, we find that multilinguals are less engaged and show lower levels of language proficiency in their second languages. We also examine the topical interests of multilingual editors and find that there is no significant difference between primary and non-primary editors in each language.

description: Artificial monolayer black phosphorus, the so-called phosphorene has attracted global interest with its distinguished anisotropic optoelectronic and electronic properties. Here, we unraveled the shear-induced direct to indirect gap transition and anisotropy diminution in phosphorene based on first-principles calculations. Lattice dynamic analysis demonstrated that phosphorene can sustain up to 10% applied shear strain. The band gap of phosphorene experiences a direct to indirect transition when 5% shear strain is applied. The electronic origin of direct to indirect gap transition from 1.54 eV at ambient condition to 1.22 eV at 10% shear strains for phosphorene was explored and the anisotropy diminution in phosphorene is discussed by calculating the maximum sound velocities, effective mass and decomposed charge density, which signals the undesired shear-induced direct to indirect gap transition in the applications of phosphorene for electronics and optoelectronics. On the other hand, the shear-induced electronic anisotropy properties suggest that phosphorene can be applied as the switcher in the nano electronic applications.

A first-order transition is observed between a low-temperature proton-ordered solid and a high-temperature proton-disordered solid. The latter is shown to possess crystalline order for the oxygen positions, arranged on a close-packed triangular lattice with AA stacking. Uniquely amongst the ice phases, the triangular bilayer is characterized by two levels of disorder (for the bonding network and for the protons) which results in a configurational entropy twice that of bulk ice.

description: AimsTo extend the previously identified association between a single nucleotide polymorphism (SNP) in neuronal acetylcholine receptor subunit alpha-5 (CHRNA5) and nicotine dependence to current smoking and initial smoking-experience phenotypes.Design, setting, participantsCase–control association study with a community-based sample, comprising 363 Caucasians and 72 African Americans (203 cases, 232 controls).MeasurementsCases had smoked ≥ five cigarettes/day for ≥ 5 years and had smoked at their current rate for the past 6 months. Controls had smoked between one and 100 cigarettes in their life-time, but never regularly. Participants also rated, retrospectively, pleasurable and displeasurable sensations experienced when they first smoked. We tested for associations between smoking phenotypes and the top 25 SNPs tested for association with nicotine dependence in a previous study.FindingsA non-synonymous coding SNP in CHRNA5, rs16969968, was associated with case status [odds ratio (OR) = 1.5, P = 0.01] and, in Caucasians, with experiencing a pleasurable rush or buzz during the first cigarette (OR = 1.6, P = 0.01); these sensations were associated highly with current smoking (OR = 8.2, P = 0.0001).ConclusionsWe replicated the observation that the minor allele of rs16969968 affects smoking behavior, and extended these findings to sensitivity to smoking effects upon experimentation. While the ability to test genetic associations was limited by sample size, the polymorphism in the CHRNA5 subunit was shown to be associated significantly with enhanced pleasurable responses to initial cigarettes in regular smokers in an a priori test. The findings suggest that phenotypes related to subjective experiences upon smoking experimentation may mediate the development of nicotine dependence.

description: Perkembangan pertanian modern (Aquaponik) banyak menarik minat lapisan masyarakat baik itu Masyarakat kalangan bawah hingga Masyarakat kalangan atas yang memiliki lahan yang terbatas,selain tidak memerlukan lahan yang luas dan waktu yang panjang,cara ini juga memberikan panen yang maksimal dengan perawatan yang tepat.Minimnya lahan kosong pada pekarangan Masyarakat Desa Pasar Kembang serta masyarakatnya yang juga banyak berprofesi sebagai petani kelapa,pinang,hingga buruh sawit yang tentunya menyita banyak waktu menjadi alasan Masyarakat tidak tertarik untuk melakukan budidaya tanaman maupun budidaya ikan.Program pengabdian menjadi respon terhadap fenomena yang terjadi di kalangan Masyarakat Desa Pasar Kembang.Masyarakat masih banyak yang belum mengetahui apa itu aquaponik dan apa saja manfaat yang akan diterima.Kegiatan ini menggunakan metode penerapan Participatory Rural Appraisal. Mahasiswa bekerja sama dengan kelompok PKK,kepala dusun,dan Masyarakat dusun. Mahasiswa juga berkesempatan mendemonstrasikan pembuatan aquaponik di hadapan masyarakat. Setelah dilakukan sosialisasi, masyarakat mendapatkan pemahaman baru dan diharapkan dapat bersikap aktif dalam pemanfaatan lahan sempit di pekarangan mereka.

description: The shortest-path, commute time, and diffusion distances on undirected graphs have been widely employed in applications such as dimensionality reduction, link prediction, and trip planning. Increasingly, there is interest in using asymmetric structure of data derived from Markov chains and directed graphs, but few metrics are specifically adapted to this task. We introduce a metric on the state space of any ergodic, finite-state, time-homogeneous Markov chain and, in particular, on any Markov chain derived from a directed graph. Our construction is based on hitting probabilities, with nearness in the metric space related to the transfer of random walkers from one node to another at stationarity. Notably, our metric is insensitive to shortest and average walk distances, thus giving new information compared to existing metrics. We use possible degeneracies in the metric to develop an interesting structural theory of directed graphs and explore a related quotienting procedure. Our metric can be computed in $O(n^3)$ time, where $n$ is the number of states, and in examples we scale up to $n=10,000$ nodes and $\approx 38M$ edges on a desktop computer. In several examples, we explore the nature of the metric, compare it to alternative methods, and demonstrate its utility for weak recovery of community structure in dense graphs, visualization, structure recovering, dynamics exploration, and multiscale cluster detection.

A novel chemo-optogenetic nanomachine sensitive to intracellular pH shifts

description: Epilepsy is a neurological disorder characterized by repeated seizures. Nowadays drugs and other approaches to reduce them are available but, unfortunately, around 30% of patients do not respond to medical therapies. In the last decade, optogenetics has emerged as a tool to both explore neuronal networks dynamics and to treat neurological conditions such as epilepsy. The optogenetics strategy involves the expression, in precise brain areas, of light sensitive proteins called opsins that are able to change the membrane potential upon wavelength-specific illumination. This last aspect is, usually, achieved using LED-based hardware. Despite the many advantages of this technique, it still faces practical and translational challenges because of the difficulties of illuminating multiple and deep areas of the brain. In this scenario, the search of alternative light sources is a goal to achieve. Luciferases are enzymes able to emit light upon addiction of their own substrate coelenterazine, and can be used to deliver light to opsins and modulate their action. In this work, the probe called pHIL (pH sensitive inhibitory luminopsin) was developed with the purpose to modulate the epileptic phenotype. pHIL is composed by a bioluminescent protein, RLuc8, coupled to the inhibitory opsin eNpHR3.0. Moreover, the control of seizures will occur only under the intracellular acidic conditions observed in epileptic neurons. The pH sensitivity of the probe is given by the presence of a pH sensor, a pH-sensitive variant of EGFP, called E2GFP. The functioning of the probe is based on the BRET mechanism. The UV light that comes from the luciferase is transferred to the E2GFP that under acidic conditions will emit light and activate the eNpHR3.0, promoting membrane hyperpolarization of epileptic neurons. pHIL is expressed and localizes at the plasma membrane in both HEK293T cells and primary hippocampal neurons. Moreover, pHIL hyperpolarizes HEK293T under acidic conditions and upon addiction of CTZ 400a, the specific luciferase substrate able to induce the UV light emission. On the basis of our data, therefore, we propose pHIL as a potential therapeutic tool to counteract neuronal hyperexcitability.

description: Despite substantial advances in global measles vaccination, measles disease burden remains high in many low- and middle-income countries. A key public health strategy for controling measles in such high-burden settings is to conduct supplementary immunization activities (SIAs) in the form of mass vaccination campaigns, in addition to delivering scheduled vaccination through routine immunization (RI) programs. To achieve balanced implementations of RI and SIAs, robust measurement of sub-national RI-specific coverage is crucial. In this paper, we develop a space-time smoothing model for estimating RI-specific coverage of the first dose of measles-containing-vaccines (MCV1) at sub-national level using complex survey data. The application that motivated this work is estimation of the RI-specific MCV1 coverage in Nigeria's 36 states and the Federal Capital Territory. Data come from four Demographic and Health Surveys, three Multiple Indicator Cluster Surveys, and two National Nutrition and Health Surveys conducted in Nigeria between 2003 and 2018. Our method incorporates information from the SIA calendar published by the World Health Organization and accounts for the impact of SIAs on the overall MCV1 coverage, as measured by cross-sectional surveys. The model can be used to analyze data from multiple surveys with different data collection schemes and construct coverage estimates with uncertainty that reflects the various sampling designs. Implementation of our method can be done efficiently using integrated nested Laplace approximation (INLA).
