Gestational diabetes mellitus (GDM) is one of the most common complications during pregnancy, with rising trend over the years. Dietary nutrient intake (protein, fat and fatty acids, carbohydrate, vitamin D, vitamin E, iron, zinc, selenium and inositol et al.), dietary pattern and probiotics may be related to GDM occurrence. Dietary factors are modifiable factors for preventing GDM. The study reviewed the roles of these dietary factors in preventing GDM. Results showed that plant-based dietary pattern may lower the risk of GDM and dietary pattern characterized with high animal protein, high fat and low carbohydrate may increase the risk of GDM...

BACKGROUND: In an effort to overcome quality and cost constraints inherent in population-based research, diverse data sources are increasingly being combined. In this paper, we describe the performance of a Medicare claims-based incident cancer identification algorithm in comparison with observational cohort data from the Nurses' Health Study (NHS). METHODS: NHS-Medicare linked participants' claims data were analyzed using 4 versions of a cancer identification algorithm across 3 cancer sites (breast, colorectal, and lung)...

Model selection approaches in phylogeography have allowed researchers to evaluate the support for competing demographic histories, which provides a mode of inference and a measure of uncertainty in understanding climatic and spatial influences on intraspecific diversity. Here, to rank all models in the comparison set, and determine what proportion of the total support the top-ranked model garners, we conduct model selection using two analytical approaches -allele frequency-based, implemented in fastsimcoal2, and gene tree-based, implemented in PHRAPL...

Cene Fišer, Christopher T Robinson, Florian Malard
The species concept is the cornerstone of biodiversity science and any paradigm shift in the delimitation of species affects many research fields. Many biologists now are embracing a new 'species' paradigm as separately evolving populations using different delimitation criteria. Individual criteria can emerge during different periods of speciation; some may never evolve. As such, a paradigm shift in the species concept relates to this inherent heterogeneity in the speciation process and species category - which is fundamentally overlooked in biodiversity research...

Despite long-time awareness of the importance of the location of buds in plant biology, research on belowground bud banks has been scant. Terms such as lignotuber, xylopodium and sobole, all referring to belowground bud-bearing structures, are used inconsistently in the literature. Because soil efficiently insulates meristems from the heat of fire, concealing buds below ground provides fitness benefits in fire-prone ecosystems. Thus, in these ecosystems, there is a remarkable diversity of bud-bearing structures...

Deep-sea clams (Bivalvia: Vesicomyidae) have been found in reduced environments over the world oceans, but taxonomy of this group remains confusing at species and supraspecific levels due to their high-morphological similarity and plasticity. In the present study, we collected mitochondrial COI sequences to evaluate the utility of DNA barcoding on identifying vesicomyid species. COI dataset identified 56 well-supported putative species/operational taxonomic units (OTUs), approximately covering half of the extant vesicomyid species...

Herein we delineate a novel route for the diastereoselective construction of diversely substituted N-heterocyclic ring systems as valuable scaffolds for natural products and pharmaceuticals, starting from easily accessible prochiral α-phenyl-β-enamino ester. The reaction sequence relies on the unexplored reactivity of α-phenyl-β-enamino ester as a nucleophilic partner in Mitsunobu reaction to forge the N-tethered alkene-alcohol/thiol/amine intermediate which was subjected to intramolecular hetero-Michael addition reaction under mild conditions to furnish the respective N-heterocyclic compounds embedded with an exocyclic chiral center in high yields and excellent diastereoselectivities...

INTRODUCTION: Recent research has shown high efficacy of HIV treatment for reducing the risk of HIV transmission to sexual partners. As the efficacy of treatment as prevention (TasP) has proliferated, a new messaging campaign, Undetectable = Untransmittable, has been gaining popularity. The purpose of this paper was to assess factors associated with the perceived accuracy of this TasP messaging strategy among a large and diverse sample of gay, bisexual, and other men who have sex with men (GBMSM) in order to inform subsequent efforts at large-scale and implementation of the HIV prevention message...

An efficient double catalytic system, combining chiral amine and 2-mercaptobenzoic acid, is applied for α',β-regioselective [4+2] annulations of 2-cyclopentenone with a diversity of activated alkenes, constructing multifunctional chiral bicycle[2,2,1]heptane scaffolds in good to excellent yields and enantioselectivities. In comparison with the traditional cross-dienamine species between 2-cyclopentenone and chiral amine, the interrupted enamine intermediate containing a covalently linked thiol catalyst shows significantly improved reactivity...

Ultrafast compound Doppler imaging based on plane-wave excitation (UCDI) can be used to evaluate cardiovascular diseases using high frame rates. In particular, it provides a fully quantifiable flow analysis over a large region of interest with high spatio-temporal resolution. However, the pulse-repetition frequency (PRF) in the UCDI method is limited for high-velocity flow imaging since it leverages between the number of plane-wave angles (<i>N</i>) and acquisition time. In this paper, we present high PRF ultrafast sliding compound Doppler imaging method (HUSDI) to improve quantitative flow analysis...

Technical benefits of additives in polymers stand in marked contrast to their associated health risks. Here, a multi-analyte method based on gas chromatography coupled to tandem mass spectrometry (GC-MS/MS) was developed to quantify polymer additives in complex matrices such as low-density polyethylene (LDPE) and isolated human skin layers after dermal exposure ex vivo. That way both technical aspects and dermal exposure were investigated. The effects of polymer additivation on the material were studied using the example of LDPE...

LGBTQ adolescents experience higher rates of mental health disorders than their heterosexual peers. The purpose of this systematic review of the literature was to examine studies evaluating social support and its effects on mental health in the LGBTQ adolescent population. Higher levels of social support were associated with positive self-esteem. Lack of social support (or low social support) was associated with higher levels of depression, anxiety, alcohol or drug misuse, risky sexual behaviors, shame, and low self-esteem...

Food recalls due to undeclared allergens or contamination are costly to the food manufacturing industry worldwide. As the industry strives for better manufacturing efficiencies over a diverse range of food products, there is a need for the development of new analytical techniques to improve monitoring the presence of unintended food allergens during the food manufacturing process. In particular, the monitoring of wash samples from cleaning in place systems (CIP), used in the cleaning of food processing equipment, would allow for the effective removal of allergen containing ingredients in between food batches...

Ecological communities typically change along gradients of human impact, though it is difficult to estimate the footprint of impacts for diffuse threats like pollution. Here we develop a joint model of benthic habitats on lagoonal coral reefs and use it to infer change in benthic composition along a gradient of distance from logging operations. The model estimates both changes in abundances of benthic groups and their compositional turn-over, a type of beta-diversity. We detect compositional turnover across the gradient and use the model to predict the footprint of turbidity impacts from logging...

Humans have shaped the population history of the horse ever since domestication about 5500 years ago. Comparative analyses of the Y chromosome can illuminate the paternal origin of modern horse breeds. This may also reveal different breeding strategies that led to the formation of extant breeds. Recently, a horse Y-chromosomal phylogeny of modern horses based on 1.46 Mb of the male-specific Y (MSY) was generated. We extended this dataset with 52 samples from five European, two American and seven Asian breeds...

Glycosylation analysis of proteins from biological sources utilizing mass-spectrometry-based approaches is challenging due to the relatively low abundance of glycopeptides, the structural diversity of glycans as well as the co-existing matrices. In this study, a customized dextran-bonded silica-based stationary phase was introduced for selective enrichment of glycopeptides and glycans from complex biological samples. This material has exhibited superior selectivity and broader glycosylation site coverage over commercial Sepharose in glycoproteomic evaluation...
