#1
Sepideh Lamei, Yue O O Hu, Tobias C Olofsson, Anders F Andersson, Eva Forsgren, Alejandra Vásquez
Honeybees face many parasites and pathogens and consequently rely on a diverse set of individual and group-level defenses to prevent disease. The crop microbiota of Apis mellifera, composed of 13 Lactic Acid Bacterial (LAB) species within the genera Lactobacillus and Bifidobacterium, form a beneficial symbiotic relationship with each other and the honeybee to protect their niche and their host. Possibly playing a vital role in honeybee health, it is important that these honeybee specific Lactic Acid Bacterial (hbs-LAB) symbionts can be correctly identified, isolated and cultured, to further investigate their health promoting properties...

The aim was to study the intake and food sources of fibre in a representative sample of Spanish adults and to analyse its association with excess body weight and abdominal obesity. A sample of 1655 adults (18-64 years) from the ANIBES ("Anthropometric data, macronutrients and micronutrients intake, practice of physical activity, socioeconomic data and lifestyles") cross-sectional study was analysed. Fibre intake and dietary food sources were determined by using a three-day dietary record. Misreporters were identified using the protocol of the European Food Safety Authority...

Errors in causal diagrams elicited from experts can lead to the omission of important confounding variables from adjustment sets and render causal inferences invalid. In this report a novel method is presented that repairs a misspecified causal diagram through the addition of edges. These edges are determined using a data-driven approach designed to provide improved statistical efficiency relative to de novo structure learning methods. Our main assumption is that the expert is "directionally informed", meaning that "false" edges provided by the expert would not create cycles if added to the "true" causal diagram...

BACKGROUND: Early-life factors can be associated with future health outcomes and are often measured by maternal recall. METHODS: We used data from the North Carolina Early Pregnancy Study and Follow-up to characterize long-term maternal recall. We used data from the Early Pregnancy Study as the gold standard to evaluate the accuracy of pre-pregnancy weight, early pregnancy behaviors, symptoms and duration of pregnancy, and child's birthweight reported at follow-up, for 109 women whose study pregnancies had resulted in a live birth...

The Vaccine Adverse Event Reporting System (VAERS) and other product surveillance systems compile reports of product-associated adverse events (AEs), and these reports may include a wide range of information including age, gender, and concomitant vaccines. Controlling for possible confounding variables such as these is an important task when utilizing surveillance systems to monitor post-market product safety. A common method for handling possible confounders is to compare observed product-AE combinations with adjusted baseline frequencies where the adjustments are made by stratifying on observable characteristics...

We report on the successful implementation of a high-resolution vacuum ultraviolet (VUV) laser pulsed field ionization-photoion (PFI-PI) detection method for the study of unimolecular dissociation of quantum-state- or energy-selected molecular ions. As a test case, we have determined the 0 K appearance energy (AE0) for the formation of methylium, CH3(+), from methane, CH4, as AE0(CH3(+)/CH4) = 14.32271 ± 0.00013 eV. This value has a significantly smaller error limit, but is otherwise consistent with previous laboratory and/or synchrotron-based studies of this dissociative photoionization onset...

Earth's energy imbalance (EEI) drives the ongoing global warming and can best be assessed across the historical record (that is, since 1960) from ocean heat content (OHC) changes. An accurate assessment of OHC is a challenge, mainly because of insufficient and irregular data coverage. We provide updated OHC estimates with the goal of minimizing associated sampling error. We performed a subsample test, in which subsets of data during the data-rich Argo era are colocated with locations of earlier ocean observations, to quantify this error...

Until recently, measurement and evaluation in sport science, especially agility testing, has not always included key elements of proper test construction. Often tests are published without reporting reliability and validity analysis for a specific population. The purpose of the present study was to examine the test re-test reliability of four versions of the 3-Cone Test (3CT), and provide guidance on proper test construction for testing agility in athletic populations. Forty male students enrolled in classes in the Department of Physical Education at a mid-Atlantic university participated...

Probir Kumar Ojha, Kunal Roy
In the present report, we have developed a predictive QSPR model using only easily computable two-dimensional (2D) descriptors from diverse classes of sweetening agents to find out the key structural properties which regulate their sweet potency. The available data set was curated to remove salts, mixtures and compounds without having a definite structure. A k-fold double cross validation technique was employed for variable selection prior to development of the final model. The final model was developed using partial least squares (PLS) regression analysis and selected based on a mean absolute error (MAE) based criteria for the validation sets...

The term sickness presenteeism (SP) has been described as the act of going to work despite having a state of health that may be regarded as poor enough to justify sick leave. SP has been observed to be prevalent among three-quarters of health care providers (HCPs). Working while sick not only puts patients at risk but also decreases productivity and increases the probability of medical errors. Moreover, SP has been identified as a risk factor for many negative health outcomes among the HCPs themselves, such as depression, burnout, and serious cardiac events...

PURPOSE: To assess reader performance and subjective workflow experience when reporting bone age studies with a digital bone age reference as compared to the Greulich and Pyle atlas (G&P). We hypothesized that pediatric radiologists would achieve equivalent results with each method while digital workflow would improve speed, experience, and reporting quality. MATERIALS AND METHODS: IRB approval was obtained for this HIPAA-compliant study. Two pediatric radiologists performed research interpretations of bone age studies randomized to either the digital (Digital Bone Age Companion, Oxford University Press) or G&P method, generating reports to mimic clinical workflow...

This work reports the effects of the genetic makeup, the environment and the genotype by environment interactions for node addition rate in an RIL population of common bean. This information was used to build a predictive model for node addition rate. To select a plant genotype that will thrive in targeted environments it is critical to understand the genotype by environment interaction (GEI). In this study, multi-environment QTL analysis was used to characterize node addition rate (NAR, node day(- 1)) on the main stem of the common bean (Phaseolus vulgaris L)...

We made a coupled genetic reporter that detects rare transcription misincorporation errors to measure RNA polymerase transcription fidelity in Escherichia coli Using this reporter, we demonstrated in vivo that the transcript cleavage factor GreA, but not GreB, is essential for proofreading of a transcription error where a riboA has been misincorporated for a riboG. A greA mutant strain had more than a 100-fold increase in transcription errors relative to wild type or a greB mutant. However, overexpression of GreB in ΔgreA cells reduced the misincorporation errors to wild-type levels demonstrating that GreB at high concentration could substitute for GreA in RNA proofreading activity in vivo...

Herein we report on a drastic release of metal ions from the Fe-bound transferrin, and Fe- or Mn-bound lactoferrin, observed upon the increase in the separation voltage during CE-based analysis. To verify whether this process is caused directly by electric field, we developed an Isothermal Voltage Increase approach (IVI), which is the extension of methods reported by Krylov et al. IVI ensures isothermal conditions while increasing separation voltage by a hydrodynamic pushing of the injected sample to the actively cooled capillary section, combined with a rationale choice of cooling temperature, dependent on the value of current...

PURPOSE: Radiation therapists play a critical role in ensuring patient safety; however, they are sometimes given insufficient time to perform quality assurance (QA) of a patient's treatment chart and documentation before the start of treatment. In this work, we show the benefits of introducing a formal therapist prestart QA checklist, completed in a quiet space well in advance of treatment, into our workflow. METHODS AND MATERIALS: A therapist prestart QA checklist was created by analyzing in-house variance reports and treatment unit delays over 6 months...

Domestic dog breeds are hosts for the brown dog tick, Rhipicephalus sanguineus sensu lato, but infestation levels vary among breeds. Beagles are less susceptible to tick infestations than English cocker spaniels due to enhanced production of 2-hexanone and benzaldehyde that act as volatile tick repellents. We report the use of prototype slow-release formulations of these compounds to reduce the burden of R. sanguineus s. l. on English cocker spaniel dogs. Twelve dogs were randomly assigned to two groups with six dogs each...
