Misperception of the Cardiovascular Risk in Patients with Rheumatoid Arthritis

The risk of cardiovascular (CV) disease and mortality is increased by rheumatoid arthritis (RA). However, data on how RA patients perceive their own CV risk and their adherence to CV prevention factors are scarce. We conducted an observational study on 266 patients with RA to determine whether the perceived CV risk correlates to the objective CV risk, and if it influences their compliance with a Mediterranean diet and physical exercise. The objective CV risk was calculated according to the modified European League Against Rheumatism (EULAR) Systematic Coronary Risk Evaluation (SCORE). The perceived CV risk did not correlate to the objective CV risk. The correlation was even lower when carotid ultrasound was used. Notably, 64.62% of patients miscalculated their CV risk, with 43.08% underestimating it. Classic CV risk factors, carotid ultrasound markers and ESR and CRP showed significant correlation with the objective CV risk. However, only hypertension and RA disease features showed association with the perceived CV risk. Neither the objective CV risk nor the perceived CV risk were associated with the accomplishment of a Mediterranean diet or physical activity. In conclusion, RA patients tend to underestimate their actual CV risk, giving more importance to RA features than to classic CV risk factors. They are not concerned enough about the beneficial effects of physical activity or diet.
PREDATION IN DIVERSIFIED AGROECOSYSTEMS: RELATIONS BETWEEN A COCCINELLID PREDATOR COLEOMEGILLA MACULATA AND ITS FOOD

SUMMARY (1) A common prediction based on ecological theory is that natural populations of insect predators will be more abundant and effective in diverse plant assemblages. Contrary to expectation, the abundance of the predaceous coccinellid beetle, Coleomegilla maculata (DeGeer), (Coleoptera: Coccinellidae) was higher on corn in monocultures than on corn in two different polycultures. In addition, predation rate by the beetle on egg masses of the European corn borer (Ostrinia nubilalis (Walker)) was higher in monocultures. (2) Important alternative resources for the beetle in these systems were aphids and pollen. Temporal dispersion of pollen and aphids was more even and species richness of the aphids was greater in the polyculture, while overall density of corn pollen and aphids was greater and their spatial distribution more even in the monoculture. (3) The higher density of evenly spaced food rewards in the corn monoculture had the greatest impact on bettle behaviour, resulting in decreased emigration and therefore greater abundance. (4) Plant diversification can have important effects on the density, species richness, and temporal and spatial dispersion of alternative resources of generalist predators. Depending on the particular effects and how a predator responds to them, the predator may be more or less abundant in the diverse system. If diversification results in a greater abundance of food resources, or a more even spatial dispersion of food, then predators can be made more abundant and effective in diversified agroecosystems.
Seaweed Essential Oils as a New Source of Bioactive Compounds for Cyanobacteria Growth Control: Innovative Ecological Biocontrol Approach

The application of natural compounds extracted from seaweeds is a promising eco-friendly alternative solution for harmful algae control in aquatic ecosystems. In the present study, the anti-cyanobacterial activity of three Moroccan marine macroalgae essential oils (EOs) was tested and evaluated on unicellular Microcystis aeruginosa cyanobacterium. Additionally, the possible anti-cyanobacterial response mechanisms were investigated by analyzing the antioxidant enzyme activities of M. aeruginosa cells. The results of EOs GC–MS analyses revealed a complex chemical composition, allowing the identification of 91 constituents. Palmitic acid, palmitoleic acid, and eicosapentaenoic acid were the most predominant compounds in Cystoseira tamariscifolia, Sargassum muticum, and Ulva lactuca EOs, respectively. The highest anti-cyanobacterial activity was recorded for Cystoseira tamariscifolia EO (ZI = 46.33 mm, MIC = 7.81 μg mL−1, and MBC = 15.62 μg mL−1). The growth, chlorophyll-a and protein content of the tested cyanobacteria were significantly reduced by C. tamariscifolia EO at both used concentrations (inhibition rate >67% during the 6 days test period in liquid media). Furthermore, oxidative stress caused by C. tamariscifolia EO on cyanobacterium cells showed an increase of the activities of superoxide dismutase (SOD) and catalase (CAT), and malondialdehyde (MDA) concentration was significantly elevated after 2 days of exposure. Overall, these experimental findings can open a promising new natural pathway based on the use of seaweed essential oils to the fight against potent toxic harmful cyanobacterial blooms (HCBs).
Sexual Difference in the Optimum Environmental Conditions for Growth and Maturation of the Brown Alga Undaria pinnatifida in the Gametophyte Stage

Undaria pinnatifida is an annual brown kelp growing naturally in coastal areas as a major primary producer in temperate regions and is cultivated on an industrial scale. Kelps have a heteromorphic life cycle characterized by a macroscopic sporophyte and microscopic sexual gametophytes. The sex-dependent effects of different environmental factors on the growth and maturation characteristics of the gametophyte stage were investigated using response surface methodology. Gametophytes were taken from three sites in Japan: Iwate Prefecture, Tokushima Prefecture, and Kagoshima Prefecture in order to confirm the sexual differences in three independent lines. Optimum temperature and light intensity were higher for males (20.7–20.9 °C and 28.6–33.7 µmol m−2 s−1, respectively) than females (16.5–19.8 °C and 26.9–32.5 µmol m−2 s−1), and maturity progressed more quickly in males than females. Optimum wavelengths of light for growth and maturation of the gametophytes were observed for both blue (400–500 nm, λmax 453 nm) and green (500–600 nm; λmax 525 nm) lights and were sex-independent. These characteristics were consistent among the three regional lines. Slower growth optima and progress of maturation could be important for female gametophytes to restrict fertilization and sporophyte germination to the lower water temperatures of autumn and winter, and suggest that the female gametophyte may be more sensitive to temperature than the male. The sexual differences in sensitivity to environmental factors improved the synchronicity of sporeling production.
Young Children’s Sugar-Sweetened Beverage Consumption and 5-Year Change in BMI: Lessons Learned from the Timing of Consumption

Sugar-sweetened beverages (SSBs) are an already known risk factor for weight gain in childhood. To identify windows of opportunity for public health interventions, insight into the consumption behavior of SSBs is needed. We investigated whether total SSB consumption was related to body mass index (BMI) change and overweight and compared whether the timing of consumption over the day differed between low and high consumers. In the Dutch GECKO Drenthe birth cohort, a cohort embedded within the Groningen Expert Center for Kids with Obesity (GECKO), height and weight were measured by trained nurses at age 5/6 years (y) and 10/11 y (N = 1257). BMI was standardized for age and sex (BMI-z). In the food pattern questionnaire completed by parents at age 5/6 y, beverages were assessed for seven time segments (breakfast, morning, lunch at school, lunch at home, afternoon, dinner, and evening). Linear and logistic regression analyses were adjusted for potential confounders (sex, baseline BMI-z, parental BMI, parental education level, maternal age at birth, maternal smoking during pregnancy). The median daily SSB consumption frequency ranged from 1.9 times per day (1.5–2.0, 25th–75th percentile) in the lowest quartile to 4.9 times per day (4.6–5.5) in the highest quartile. In the highest compared to the lowest quartile of SSB consumption frequency, the confounder-adjusted odds ratio for overweight incidence was 3.12 (95% CI, 1.60–6.07). The difference in consumption between quartile 1 and quartile 4 occurred mainly during main meals and in the evening, e.g., at breakfast (31% vs. 98%, p < 0.001), lunch at home (32% vs. 98%, p < 0.001), and dinner (17% vs. 72%, p < 0.001). These drinking occasions characterizing high SSB consumers mostly occurred in the home environment, where parental influence on dietary behaviors is profound. Therefore, these results exposed a window of opportunity, leading to the advice for parents to offer their children sugar-free drinks to quench thirst with main meals.
DispHred: A Server to Predict pH-Dependent Order–Disorder Transitions in Intrinsically Disordered Proteins

The natively unfolded nature of intrinsically disordered proteins (IDPs) relies on several physicochemical principles, of which the balance between a low sequence hydrophobicity and a high net charge appears to be critical. Under this premise, it is well-known that disordered proteins populate a defined region of the charge–hydropathy (C–H) space and that a linear boundary condition is sufficient to distinguish between folded and disordered proteins, an approach widely applied for the prediction of protein disorder. Nevertheless, it is evident that the C–H relation of a protein is not unalterable but can be modulated by factors extrinsic to its sequence. Here, we applied a C–H-based analysis to develop a computational approach that evaluates sequence disorder as a function of pH, assuming that both protein net charge and hydrophobicity are dependent on pH solution. On that basis, we developed DispHred, the first pH-dependent predictor of protein disorder. Despite its simplicity, DispHred displays very high accuracy in identifying pH-induced order/disorder protein transitions. DispHred might be useful for diverse applications, from the analysis of conditionally disordered segments to the synthetic design of disorder tags for biotechnological applications. Importantly, since many disorder predictors use hydrophobicity as an input, the here developed framework can be implemented in other state-of-the-art algorithms.
Habitat Selection by Birds of Riparian Communities: Evaluating Effects of Habitat Alterations

Avifauna of riparian communities were studied in Iowa during late spring and early summer. Birds were censused on 28 study plots representing a habitat gradient from hayfields to closed-canopy woodlands. An index of nesting niche breadth was determined for 18 open-nesting bird species on the basis of vegetation life form(s) used for nesting, and for 10 cavity-nesting species on the basis of type(s) of nest-cavity support. Cavity-nesters preferred soft snags as nest sites. Floodplain woodlands supported higher densities of breeding birds than upland woodland or herbaceous habitats. Bird species richness increased (P < 0.01) with the width of wooded riparian habitats. Wooded habitats supported a maximum of 32 species; herbaceous habitats, 8. Observation frequencies of 41 bird species in 6 general habitat types were used to calculate indices of tolerance to habitat alteration. Microhabitat characteristics selected by each species were determined by comparing bird observation frequencies with 36 vegetation variables, using stepwise multiple regression. The potential effects of 6 alterations to wooded riparian habitats on the 41 species are predicted. J. WILDL. MANAGE. 44(1):1-15 Riparian habitats are critical to wildlife, especially in regions with intensive agriculture where streamside habitat is being depleted rapidly. Nongame birds constitute a major component of riparian wildlife communities, but most research concerning nongame bird management has been local in nature or concerned with endangered species (Robbins and Erskine 1975). Recently, contributors to several symposia have emphasized the need for research on management of all nongame birds (Smith 1975; DeGraaf 1978a,b). Such research is essential to assess the impacts of habitat alterations on the associated wildlife (Lennartz and Bjugstad 1975). Our study is an attempt to satisfy part of that need. Our objectives were to quantify factors critical in nest-site and habitat selection by breeding birds of riparian communities over a range of habitat types and to use the results to evaluate effects of habitat perturbations on avian communities. The results are applicable to both riparian and upland habitats of the Central Plains and, with caution, could be used in other areas as well. We are grateful to the landowners of Guthrie County, Iowa, for their cooperation in all phases of the field work. T. Rosburg and R. Deitchler assisted in collecting field data. D. F. Cox, L. Wolins, M. Hand, and B. J. Meador provided help with the statistics and computer analysis. J. J. Dinsmore, R. B. Dahlgren, and R. Q. Landers reviewed an earlier draft of the manuscript. The manuscript also benefited from the suggestions of 2 anonymous referees.
Critical Analysis of Genome-Wide Association Studies: Triple Negative Breast Cancer Quae Exempli Causa

Genome-wide association studies (GWAS) are useful in assessing and analyzing either differences or variations in DNA sequences across the human genome to detect genetic risk factors of diseases prevalent within a target population under study. The ultimate goal of GWAS is to predict either disease risk or disease progression by identifying genetic risk factors. These risk factors will define the biological basis of disease susceptibility for the purposes of developing innovative, preventative, and therapeutic strategies. As single nucleotide polymorphisms (SNPs) are often used in GWAS, their relevance for triple negative breast cancer (TNBC) will be assessed in this review. Furthermore, as there are different levels and patterns of linkage disequilibrium (LD) present within different human subpopulations, a plausible strategy to evaluate known SNPs associated with incidence of breast cancer in ethnically different patient cohorts will be presented and discussed. Additionally, a description of GWAS for TNBC will be presented, involving various identified SNPs correlated with miRNA sites to determine their efficacies on either prognosis or progression of TNBC in patients. Although GWAS have identified multiple common breast cancer susceptibility variants that individually would result in minor risks, it is their combined effects that would likely result in major risks. Thus, one approach to quantify synergistic effects of such common variants is to utilize polygenic risk scores. Therefore, studies utilizing predictive risk scores (PRSs) based on known breast cancer susceptibility SNPs will be evaluated. Such PRSs are potentially useful in improving stratification for screening, particularly when combining family history, other risk factors, and risk prediction models. In conclusion, although interpretation of the results from GWAS remains a challenge, the use of SNPs associated with TNBC may elucidate and better contextualize these studies.
Validation of Spatiotemporal and Kinematic Measures in Functional Exercises Using a Minimal Modeling Inertial Sensor Methodology

This study proposes a minimal modeling magnetic, angular rate and gravity (MARG) methodology for assessing spatiotemporal and kinematic measures of functional fitness exercises. Thirteen healthy persons performed repetitions of the squat, box squat, sandbag pickup, shuffle-walk, and bear crawl. Sagittal plane hip, knee, and ankle range of motion (ROM) and stride length, stride time, and stance time measures were compared for the MARG method and an optical motion capture (OMC) system. The root mean square error (RMSE), mean absolute percentage error (MAPE), and Bland–Altman plots and limits of agreement were used to assess agreement between methods. Hip and knee ROM showed good to excellent agreement with the OMC system during the squat, box squat, and sandbag pickup (RMSE: 4.4–9.8°), while ankle ROM agreement ranged from good to unacceptable (RMSE: 2.7–7.2°). Unacceptable hip and knee ROM agreement was observed for the shuffle-walk and bear crawl (RMSE: 3.3–8.6°). The stride length, stride time, and stance time showed good to excellent agreement between methods (MAPE: (3.2 ± 2.8)%–(8.2 ± 7.9)%). Although the proposed MARG-based method is a valid means of assessing spatiotemporal and kinematic measures during various exercises, further development is required to assess the joint kinematics of small ROM, high velocity movements.
In Vivo siRNA Delivery to Immunosuppressive Liver Macrophages by α-Mannosyl-Functionalized Cationic Nanohydrogel Particles

Macrophages are the front soldiers of the innate immune system and are vital for immune defense, tumor surveillance, and tissue homeostasis. In chronic diseases, including cancer and liver fibrosis, macrophages can be forced into an immunosuppressive and profibrotic M2 phenotype. M2-type macrophages overexpress the mannose receptor CD206. Targeting these cells via CD206 and macrophage repolarization towards an immune stimulating and antifibrotic M1 phenotype through RNA interference represents an appealing therapeutic approach. We designed nanohydrogel particles equipped with mannose residues on the surface (ManNP) that delivered siRNA more efficiently to M2 polarized macrophages compared to their untargeted counterparts (NonNP) in vitro. The ManNP were then assessed for their in vivo targeting potential in mice with experimental liver fibrosis that is characterized by increased profibrotic (and immunosuppressive) M2-type macrophages. Double-labelled siRNA-loaded ManNP carrying two different near infrared labels for siRNA and ManNP showed good biocompatibility and robust uptake in fibrotic livers as assessed by in vivo near infrared imaging. siRNA–ManNP were highly colocalized with CD206+ M2-type macrophages on a cellular level, while untargeted NP (NonNP) showed little colocalization and were non-specifically taken up by other liver cells. ManNP did not induce hepatic inflammation or kidney dysfunction, as demonstrated by serological analysis. In conclusion, α-mannosyl-functionalized ManNP direct NP towards M2-type macrophages in diseased livers and prevent unspecific uptake in non-target cells. ManNP are promising vehicles for siRNA and other drugs for immunomodulatory treatment of liver fibrosis and liver cancer.
Musical Experience Offsets Age-Related Decline in Understanding Speech-in-Noise: Type of Training Does Not Matter, Working Memory Is the Key.

OBJECTIVES Speech comprehension under "cocktail party" scenarios deteriorates with age even in the absence of measurable hearing loss. Musical training is suggested to counteract the age-related decline in speech-in-noise (SIN) perception, yet which aspect of musical plasticity contributes to this compensation remains unclear. This study aimed to investigate the effects of musical experience and aging on SIN perception ability. We hypothesized a key mediation role of auditory working memory in ameliorating deficient SIN perception in older adults by musical training. DESIGN Forty-eight older musicians, 29 older nonmusicians, 48 young musicians, and 24 young nonmusicians all with (near) normal peripheral hearing were recruited. The SIN task was recognizing nonsense speech sentences either perceptually colocated or separated with a noise masker (energetic masking) or a two-talker speech masker (informational masking). Auditory working memory was measured by auditory digit span. Path analysis was used to examine the direct and indirect effects of musical expertise and age on SIN perception performance. RESULTS Older musicians outperformed older nonmusicians in auditory working memory and all SIN conditions (noise separation, noise colocation, speech separation, speech colocation), but such musician advantages were absent in young adults. Path analysis showed that age and musical training had opposite effects on auditory working memory, which played a significant mediation role in SIN perception. In addition, the type of musical training did not differentiate SIN perception regardless of age. CONCLUSIONS These results provide evidence that musical training offsets age-related speech perception deficit at adverse listening conditions by preserving auditory working memory. Our findings highlight auditory working memory in supporting speech perception amid competing noise in older adults, and underline musical training as a means of "cognitive reserve" against declines in speech comprehension and cognition in aging populations.
Rapid maturation of unilateral cataract in leptospirosis

Leptospirosis is a bacterial cause for nongranulomatous uveitis in tropical countries. It is known to cause rapid maturation of cataract in young adults. Here we present six patients who had presenting sign as fully matured pearly white unilateral cataract without history of any trauma in their first visit. All except one patient were positive for leptospirosis by ELISA testing. Histopathological analyses of those lenses showed globular degeneration.
Hydrolytic Degradation of Porous Crosslinked Poly(ε-Caprolactone) Synthesized by High Internal Phase Emulsion Templating

Porous poly(ε-caprolactone) (PCL) scaffolds were fabricated using the high internal polymerization emulsion (HIPE) technique. Bis(ε-caprolactone-4-yl) (BCY) was utilized as crosslinker. The crosslinking density and the volume fraction of the dispersed phase were varied in order to study the potential effect of these parameters on the hydrolytic degradation at 37 °C and 60 °C. After different hydrolysis times the remaining solid samples were analyzed by Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM), while the degradation products in the aqueous aging solutions were analyzed by laser desorption ionization-mass spectrometry (LDI-MS). The effect of temperature on the degradation process and release of degradation products was, as expected, significant. The temperature effect was also shown by FTIR analysis that displayed a pronounced increase in the intensity of the hydroxyl-group absorption band after 70 days of hydrolysis at 60 °C indicating significant cleavage of the polymer chains. LDI-MS analysis proved the release of oligomers ranging from dimers to hexamers. The product patterns were similar, but the relative m/z signal intensities increased with increasing time, temperature and crosslinking density, indicating larger amounts of released products. The latter is probably due to the decreasing degree of crystallinity as a function of amount of crosslinker. The porous structure and morphology of the scaffolds were lost during the aging. The higher the crosslinking density, the longer the scaffolds retained their original porous structure and morphology.
