Dining outside of the home can be difficult for persons with food allergies who must rely on restaurant staff to properly prepare allergen-free meals. The purpose of this study was to understand and identify factors associated with food allergy knowledge and attitudes among restaurant managers, food workers, and servers. This study was conducted by the Environmental Health Specialists Network (EHS-Net), a collaborative forum of federal, state, and local environmental health specialists working to understand the environmental factors associated with food safety issues...

Virtually all intercalation compounds exhibit significant changes in unit cell volume as the working ion concentration varies. NaxFePO4 (0<x<1, NFP) olivine, of interest as a cathode for sodium-ion batteries, is a model for topotactic, high strain systems as it exhibits one of the largest discontinuous volume changes (~17% by volume) during its first-order transition between two otherwise isostructural phases. Using synchrotron radiation powder X-ray diffraction (PXD) and pair distribution function (PDF) analysis, we discover a new strain-accommodation mechanism wherein an amorphous phase forms to buffer the large lattice mismatch between primary phases...

The U.S. Food and Drug Administration (FDA) regulates products accounting for 20% of U.S. consumer spending. Many of its actions depend on assumptions about behavior. Will people heed food recall notices? Will they follow medication schedules? Will they have realistic expectations regarding the benefits and risks of new products? Over time, FDA has increasingly made psychology integral to its processes for answering such questions. That progress has come when windows of opportunity have found psychologists with science relevant to FDA's needs, FDA with staff who can translate that research into agency terms, and a regulatory arena that can accommodate behavioral evidence...

The present study investigated the development of fraction comparison strategies through a longitudinal analysis of children's responses to a fraction comparison task in 4th through 6th grades (N = 394). Participants were asked to choose the larger value for 24 fraction pairs blocked by fraction type. Latent class analysis of performance over item blocks showed that most children initially exhibited a "whole number bias," indicating that larger numbers in numerators and denominators produce larger fraction values...

BACKGROUND AND OBJECTIVES: Variant RHD genes associated with the weak D phenotype can result in complete or partial D-epitope expression on the red cell. This study examines the genetic classification in Australian blood donors with a weak D phenotype and correlates RHD variants associated with the weak D phenotype against D-epitope profile. MATERIALS AND METHODS: Following automated and manual serology, blood samples from donors reported as 'weak D' (n = 100) were RHD genotyped by a commercial SNP-typing platform and Sanger sequencing...

OBJECTIVE: Familial aspects of pediatric obsessive-compulsive disorder (OCD), including accommodation and treatment, have received notable and warranted attention. However, individual perspectives of its repercussions on family functioning, including emotional and occupational parental burden, have not been closely examined. The present study details this topic using a large multicenter sample. METHOD: Participants included 354 youth affected with OCD and their mothers and fathers ascertained through OCD programs in Boston, Massachusetts (n = 180) and Vancouver, British Columbia (n = 174)...

BACKGROUND: The determination of specific kinase substrates in vivo is challenging due to the large number of protein kinases in cells, their substrate specificity overlap, and the lack of highly specific inhibitors. In the late 90s, Shokat and coworkers developed a protein engineering-based method addressing the question of identification of substrates of protein kinases. The approach was based on the mutagenesis of the gatekeeper residue within the binding site of a protein kinase to change the co-substrate specificity from ATP to ATP analogues...

Uncontrolled regulation of specific metalloenzymes plays important roles in several diseases like tumor metastasis and inflammation. Therefore, selective metalloenzyme inhibition may be a potential target for drug design and development. Matrix metalloproteinase inhibitors (MMPIs) opened up a new horizon as the possible treatment of arthritis, cancer, and emphysema. However, due to adverse effects and poor pharmacokinetics, first generation MMPIs failed in clinical trials. Therefore, development of potential and selective MMPIs is still in demand...

The urinary tract is subject to frequent challenges from the gut microflora. Indeed, up to 40% of women will experience at least one urinary tract infection (UTI) during their lifetime. Uropathogenic Escherichia coli (UPEC) contribute to an overwhelming majority of these cases and they typically initiate UTIs by invading the superficial epithelium that lines the bladder lumen. In addition to serving as an effective barrier to noxious agents found in urine, bladder epithelial cells (BECs) play a key physiological role in regulating bladder volume to accommodate urine flow...

More and more large cohort studies have conducted or are conducting genome-wide association studies (GWAS) to reveal the genetic components of many complex human diseases. These large cohort studies often collected a broad array of correlated phenotypes that reflect common physiological processes. By jointly analyzing these correlated traits, we can gain more power by aggregating multiple weak effects and shed light on the mechanisms underlying complex human diseases. The majority of existing multi-trait association test methods are based on jointly modeling the multivariate traits conditional on the genotype as covariate, and can readily accommodate the imputed SNPs by using their imputed dosage as a covariate...

The first successful use of nanoparticles (NPs) for vaccination was reported almost 40 years ago with a virus-like particle-based vaccine against Hepatitis B. Since then, the term NP has been expanded to accommodate a large number of novel nano-sized particles engineered from a range of materials. The great interest in NPs is likely not only a result of the two successful vaccines against hepatitis B and Human Papilloma Virus (HPV) that use this technology, but also due to the versatility of those small-sized particles, as indicated by the wide range of applications reported so far, ranging from medicinal and cosmetics to purely technical applications...

The catalytic mechanism of the NAD(P)(+)-dependent aldehyde dehydrogenases (ALDHs) involves the nucleophilic attack of the essential cysteine (Cys302, mature HsALDH2 numbering) on the aldehyde substrate. Although oxidation of Cys302 will inactivate these enzymes, it is not yet well understood how this oxidation is prevented. In this work we explore possible mechanisms of protection by systematically analyzing the reported three-dimensional structures and amino acid sequences of the enzymes of the ALDH superfamily...

Peripheral nerves are susceptible to stretch injury [1-4] and incorporate structural waviness at the level of the axons, fascicles, and nerve trunk to accommodate physiological increases in length [5, 6]. It is unknown whether there are limits to the amount of deformation that waviness can accommodate. In rorqual whales, a sub-group of baleen whales, nerves running through the ventral groove blubber (VGB) associated with the floor of the mouth routinely experience dramatically large deformations. In fact, some of these nerves more than double their length during lunge feeding and then recoil to a short, compressed state after each lunge [7-9]...

RNAi is broadly used to map gene regulatory networks, but the identification of genes that are responsible for the observed phenotypes is challenging, as small interfering RNAs (siRNAs) simultaneously downregulate the intended on targets and many partially complementary off targets. Additionally, the scarcity of publicly available control datasets hinders the development and comparative evaluation of computational methods for analyzing the data. Here, we introduce PheLiM (https://github.com/andreariba/PheLiM), a method that uses predictions of siRNA on- and off-target downregulation to infer gene-specific contributions to phenotypes...

The Netherlands is important for wintering migratory herbivorous geese, numbers of which have rapidly increased, leading to conflict with agriculture. In 2005/2006, a new goose management policy aimed to limit compensation payments to farmers by concentrating foraging geese in 80 000 ha of designated 'go' areas-where farmers received payment to accommodate them-and scaring geese from 'no go' areas elsewhere. Monthly national counts of four abundant goose species during 10 years prior to the new policy and in 8 years following implementation found that 57% of all goose days were spent within 'go' areas under the new management, the same as prior to implementation...

Many goose species feed on agricultural land, and with growing goose numbers, conflicts with agriculture are increasing. One possible solution is to designate refuge areas where farmers are paid to leave geese undisturbed. Here, we present a generic modelling tool that can be used to designate the best locations for refuges and to gauge the area needed to accommodate the geese. With a species distribution model, locations are ranked according to goose suitability. The size of the area to be designated as refuge can be chosen by including more or less suitable locations...

To facilitate mass transport and column efficiency, solutes must have free access to particle pores to facilitate interactions with the stationary phase. To ensure this feature, particles should be used for HPLC separations which have pores sufficiently large to accommodate the solute without restricted diffusion. This paper describes the design and properties of superficially porous (also called Fused-Core(®), core shell or porous shell) particles with very large (1000Å) pores specifically developed for separating very large biomolecules and polymers...
