Adaptive interventions are an emerging class of behavioral interventions that allow for individualized tailoring of intervention components over time to a person's evolving needs. The purpose of this study was to evaluate an adaptive step goal + reward intervention, grounded in Social Cognitive Theory delivered via a smartphone application (Just Walk), using a mixed modeling approach. Participants (N = 20) were overweight (mean BMI = 33.8 ± 6.82 kg/m(2)), sedentary adults (90% female) interested in participating in a 14-week walking intervention...

Inhibition of anaerobic digestion (AD) due to perturbation caused by substrate composition and/or operating conditions can significantly reduce performance. Such perturbations could be limited by elucidating microbial community response to inhibitors and devising strategies to increase community resilience. To this end, advanced molecular methods are increasingly being applied to study the AD microbiome, a diverse community of microbial populations with complex interactions. This literature review of AD inhibition studies indicates that inhibitory concentrations are highly variable, likely stemming from differences in community structure or activity profile and previous exposure to inhibitors...

Inadequate feed consumption reduces intestinal barrier function in both ruminants and monogastrics. Objectives were to characterize how progressive feed restriction (FR) affects inflammation, metabolism, and intestinal morphology, and to investigate if glucagon-like peptide 2 (GLP2) administration influences the aforementioned responses. Twenty-eight Holstein cows (157 ± 9 d in milk) were enrolled in 2 experimental periods. Period 1 [5 d of ad libitum (AL) feed intake] served as baseline for period 2 (5 d), during which cows received 1 of 6 treatments: (1) 100% of AL feed intake (AL100; n = 3), (2) 80% of AL feed intake (n = 5), (3) 60% of AL feed intake (n = 5), (4) 40% of AL feed intake (AL40; n = 5), (5) 40% of AL feed intake + GLP2 administration (AL40G; 75 µg/kg of BW s...

Bovine satellite cell (bSC) myogenesis and skeletal muscle hypertrophy occur through the orchestrated actions of multiple autocrine and paracrine growth factors. Intimate to the bSC niche is IL6, a dual-purpose cytokine with proinflammatory and mitogenic properties. The objective of the experiment was to examine the effects of IL6 on proliferation and differentiation of bSC in vitro. Treatment of primary bSC cultures with recombinant bovine IL6 (bIL6) failed to alter myogenesis owing to the absence of intracellular signal transduction...

BACKGROUND: Despite recommendations against the use of splash basins, due to the potential of bacterial contamination, our observation has been that they continue to be used in operating theaters. In hopes of decontaminating the splash basin, we sought to determine if the addition of chlorhexidine gluconate (CHG) would eliminate aerobic bacterial growth within the splash basin. METHODS: After Institutional Review Board approval, we began enrollment in a randomized controlled trial comparing 2 splash basin solutions...

Hepatitis B core Antigen (HBcAg) assembled into Capsid-Like Particles (CLPs) is investigated as a therapeutic vaccine in treatment of chronic hepatitis B (CHB) and in diagnostic tests or as a carrier for various epitopes. While the expression of HBcAg has been thoroughly clarified in E. coli and yeast, it has also been investigated in other expression systems. Stably transformed tobacco expressed HBcAg at a level of 110-250µg/g fresh weight, therefore in view of its large leaf biomass it offers a production platform comparable with transient expression systems regarding the final yield of HBcAg...

Tritrichomonas foetus (T. foetus) is a flagellated protozoa that infects the distal ileum and proximal colon of domestic cats, as well as the urogenital tract of cattle. Feline trichomonosis is recognized as a prevalent cause of chronic diarrhea in cats worldwide. The suspected route of transmission is fecal-oral, with cats in densely crowded environments at highest risk for infection. Thus, the recommended strategy for minimizing spread of infection is to identify and isolate T. foetus-positive cats from the general population...

Cadaveric organ transplantation represents the definitive treatment option for end-stage disease but is restricted by the shortage of clinically-viable donor organs. This limitation has, in part, driven current research efforts for in vitro generation of transplantable tissue surrogates. Recent advances in organ reconstruction have been facilitated by the re-purposing of decellularized whole organs to serve as three-dimensional bio-scaffolds. Notably, studies in rodents indicate that such scaffolds retain native extracellular matrix components that provide appropriate biochemical, mechanical and physical stimuli for successful tissue/organ reconstruction...

Ru(II) and Os(II) complexes of 2-pyridinecarbothioamide ligands were introduced as orally administrable anticancer agents (S.M. Meier, M. Hanif, Z. Adhireksan, V. Pichler, M. Novak, E. Jirkovsky, M.A. Jakupec, V.B. Arion, C.A. Davey, B.K. Keppler, C.G. Hartinger, Chem. Sci., 2013, 4, 1837-1846). In order to identify structure-activity relationships, a series of N-phenyl substituted pyridine-2-carbothiamides (PCAs) were obtained by systematically varying the substituents at the phenyl ring. The PCAs were then converted to their corresponding Ru(II)(η(6)-p-cymene) complexes and characterized spectroscopically and by X-ray diffraction as well as in terms of stability in water and HCl...

BACKGROUND: Numerous studies suggest that radiation can boost antitumor immune response by stimulating release of tumor-specific antigens. However, the optimal timing between radiotherapy and immune checkpoint blockade to achieve potentially synergistic benefits is unclear. MATERIAL AND METHODS: Multi-institutional retrospective analysis was conducted of ninety-nine metastatic melanoma patients from 2007 to 2014 treated with ipilimumab who later received stereotactic radiosurgery (SRS) for new brain metastases that developed after starting immunotherapy...

BACKGROUND: Besides acting as definitive hosts for Echinococcus multilocularis, dogs can become infected by the larval form of this parasite and thereby develop life-threatening alveolar echinococcosis (AE). Although AE is a zoonotic disease, most therapeutic and diagnostic approaches have been developed for human patients. In dogs, AE is typically diagnosed in the advanced stage of the disease when the parasitic mass has already caused abdominal distension. At that stage, complete resection of the parasitic mass is often impossible, leaving a guarded prognosis for the affected dogs...

Characteristics of soil organic matter (SOM) are important, especially in the Amazon region, which represents one of the world's most relevant carbon reservoirs. In this work, the concentrations of carbon and differences in its composition (humification indexes) were evaluated and compared for several horizons (0 to 390cm) of three typical Amazonian podzol profiles. Fluorescence spectroscopy was used to investigate the humic acid (HA) fractions of SOM isolated from the different samples. Simple and labile carbon structures appeared to be accumulated in surface horizons, while more complex humified compounds were leached and accumulated in intermediate and deeper Bh horizons...
