BACKGROUND: Zinc-finger BED domain-containing 3 (Zbed3) is a member of the zinc-finger domain protein superfamily. Recent studies have shown that Zbed3 is associated with insulin resistance and type 2 diabetes mellitus. However, no report has demonstrated the association of Zbed3 with metabolic syndrome (MetS) in humans. The purpose of this study is to examine the association between Zbed3 and MetS in a cross-sectional study. METHODS: We conducted a cross-sectional study of a Chinese population, including 167 non-MetS subjects and 144 newly diagnosed MetS (nMetS) patients...

AIMS: Individual sensitivity to glucocorticoid (GC) therapy might play a pivotal role in the development of GC-induced avascular necrosis of the femoral head (GANFH). In a growing number of studies, common polymorphisms of the glucocorticoid receptor gene (nuclear receptor subfamily 3 group C member 1 [NR3C1]) have been associated with variability in the individual sensitivity to GCs. However, whether the NR3C1 gene polymorphisms actually influence the susceptibility of GANFH remains unknown...

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 design paradigm of biomaterials has been changed to ones with favorable immunomodulatory effects, indicating the importance of accurately evaluating the immunomodulatory properties of biomaterials. Among all the immune cells macrophages receive most attention, due to their plasticity and multiple roles in the materials and host interactions, and thereby become model immune cells for the evaluation of immunomodulatory properties of biomaterials in many studies. Lipopolysaccharides (LPS), a polysaccharide in the outer membrane of Gram-negative bacteria, elicit strong immune responses, which was often applied to activate macrophages, resulting in a proinflammatory M1 phenotype, and the release of proinflammatory cytokines, including tumor necrosis factor alpha (TNFα), interleukin (IL)-1, and IL-6...

Poly(glycerol sebacate) (PGS) has been used successfully as a scaffolding material for soft tissue engineering. PGS scaffolds, however, are usually mechanically isotropic, which may restrict their use in tissue repairs as many soft tissues in the body have anisotropic mechanical behaviors. Although various methods have been used to fabricate anisotropic scaffolds, it remains challenging to make anisotropic scaffolds from thermoset PGS. Here a new, simple method to fabricate an anisotropic PGS membrane which can then be used to construct thicker three-dimensional anisotropic scaffolds was developed...

The Internet has become a popular resource for patient education. The information it provides, however, is rarely peer-reviewed, and its quality may be a concern. Since the average American reads at an 8th grade level, the American Medical Association and the National Institutes of Health have recommended that health information be written at a 4th to 6th grade level. We performed a study to assess the quality and readability of online information regarding the treatment of swallowing disorders. A Google search for "swallowing treatment" was conducted...

Prophages are major contributors to horizontal gene transfer and drive the evolution and diversification of bacteria. Here, we describe the characterization of a prophage element designated pp3 in the clinical Pseudomonas aeruginosa isolate PA1. pp3 spontaneously excises from the PA1 genome and circularizes at a very high frequency of 25%. pp3 is likely to be a defective prophage due to its inability to form plaques on P. aeruginosa indicator strains, and no phage particles could be detected in PA1 supernatants...

This paper considers the problem of direction-of-arrival (DOA) estimation of coherent signals on passive coprime arrays, where we resort to the fourth-order cumulants of the received signal to explore more information. A fourth-order cumulant matrix (FCM) is introduced for the coprime array. The special structure of the FCM is combined with the array configuration to resolve the coherent signals. Since each sparse array of a coprime array is uniform, a series of overlapping identical subarrays can be extracted...

Riboswitches regulate gene expression through direct and specific interactions with small metabolite molecules. Binding of a ligand to its RNA target is high selectivity and affinity and induces conformational changes of the RNA's secondary and tertiary structure. The structural difference of two purine riboswitches aptamers is caused by only one single mutation, where cytosine 74 in the guanine riboswitch is corresponding to a uracil 74 in adenine riboswitch. Here we employed molecular dynamics (MD) simulation, molecular mechanics Poisson Boltzmann surface area (MM-PBSA) and thermodynamic integration computational methodologies to evaluate the energetic and conformational changes of ligands binding to purine riboswitches...
