Structure of everyday memory in adults with age-associated memory impairment

Everyday memory was tested in a group of adults manifesting Age-Associated Memory Impairment; a computerized battery of tests was constructed to simulate memory tasks of daily life. Confirmatory and other structural equation models were estimated for the entire sample of 273 Ss and for 3 age groups. A 4-factor model was found to fit the data well and was invariant across age and gender. After education had been controlled, only the General Recall factor was found to be consistently related to age in both men and women; the other 3 factors--Narrative Memory, Digit Recall, and Visual Memory--were related to age only in men. Confirmatory factor analyses of the everyday memory tests combined with several psychometric memory tests suggested that some of the latter (the Benton Visual Retention Test and Wechsler Memory Scale Hard Paired Associates) load on more than 1 factor of everyday memory, suggesting complex relationships between the 2 types of tests.
Construction Safety Risk Assessment of Bridges in the Marine Environment Based on CRITIC and TOPSIS Models

ABSTRACT Wu, H. ; Liu, S. ; Wang, J., and Yang, T. , 2020. Construction safety risk assessment of bridges in the marine environment based on CRITIC and TOPSIS models. In: Yang, D.F. and Wang, H. (eds.), Recent Advances in Marine Geology and Environmental Oceanography. Journal of Coastal Research, Special Issue No. 108, pp. 206–210. Coconut Creek (Florida), ISSN 0749-0208. To accurately assess the safety risk level of bridge construction in the marine environment, this study puts forward a safety risk evaluation model by comprehensively using the CRITIC and TOPSIS methods. First, from the five dimensions of men, machines, materials, methods, and environment, this paper identified and constructed a construction safety risk evaluation index system for bridges in the marine environment, aided by expert opinions and literature research. This index system included 16 secondary indexes, and the risk classification standard of each index was determined. Then, the CRITIC model was used to calculate the weights of secondary indexes, and the TOPSIS model was used to evaluate the risk level of construction safety. The results for Tangshan Zhongshan Bridge Project showed the key technology scheme, and the key technologies that had the greatest weight. The risk level of this bridge was medium risk, and its construction safety risk level was the highest in spring. The case analysis in this paper is consistent with engineering practice, which proves the scientific suitability effectiveness of the method proposed in this paper.
Studying the Interplay Between Apolipoprotein E and Education on Cognitive Decline in Centenarians Using Bayesian Beta Regression

Apolipoprotein E (APOE) is an important risk factor for cognitive decline and Alzheimer’s disease in aging individuals. Among the 3 known alleles of this gene: e2, e3, and e4, the e4 allele is associated with faster cognitive decline and increased risk for Alzheimer’s and dementia, while the e2 allele has a positive effect on longevity, and possibly on preservation of cognitive function. Education also has an important effect on cognition and longevity but the interplay between APOE and education is not well-characterized. Previous studies of the effect of APOE on cognitive decline often used linear regression with the normality assumption, which may not be appropriate for analyzing bounded and skewed neuropsychological test scores. In this paper, we applied Bayesian beta regression to assess the effect of APOE alleles on cognitive decline in a cohort of centenarians with longitudinal assessment of their cognitive function. The analysis confirmed the negative association between older age and cognition and the beneficial effect of education that persists even at the extreme of human lifespan in carriers of the e3 allele. In addition, the analysis showed an association between APOE and cognition that is modified by education. Surprisingly, an antagonistic interaction existed between higher education and APOE alleles, suggesting that education may reduce the positive effect of APOE e2 and increase the negative effect of APOE e4 at extreme old age.
Dynamics Analysis and Numerical Simulation of An Amended HBV Infection Model

This paper proposes an amended hepatitis B virus(HBV) infection mathematical model,which has immune response term and alanine aminotransferase(ALT) term.This model has three equilibrium points:virus free equilibrium point Q_1,immune depletion equilibrium point Q_2 and persistent infection equilibrium point Q_3. We prove that if a basic virus reproductive number R_0 1,then Q_1 of the model is globally asymptotically stable;if R_0 1,then Q_2 of the model is globally asymptotically stable.This result implies that if an HBV infected patient's R_0 1,then the patient will eventually recover even if infected with a large amount of virus.Numerical simulation result of the model shows that Tenofovir Disoproxil Fumurate(TDF) anti-HBV therapy can activate patients' ability of cytokine-midiated noncytolytic HBV clearance,which clears HBV directly and almost does not damage patients' hepatocytes.
Empirical Research on the Interaction between Marine Scientific and Technological Innovation and Marine Economic Development

ABSTRACT Yu, D. and Zou, Z. , 2020. Empirical research on the interaction between marine scientific and technological innovation and marine economic development. In: Yang, D.F. and Wang, H. (eds.), Recent Advances in Marine Geology and Environmental Oceanography. Journal of Coastal Research, Special Issue No. 108, pp. 7–11. Coconut Creek (Florida), ISSN 0749-0208. Scientific and technological innovation is of great significance to marine economic growth. This study selected marine technology innovation and marine economic growth data from 2005 to 2017 of Hainan Province, China, and constructed a vector autoregressive model to conduct an empirical analysis of the interactive relationship between marine technological innovation and marine economic growth in Hainan. The results show that there is a significant co-integration relationship between investment in scientific and technological innovation and economic growth. The growth of Hainan's marine economy is the Granger cause for the increase in the number of scientific researchers in area marine scientific institutions; the increase in marine scientific research personnel and the increase of marine scientific research funding in turn will drive marine economy development. Based on the above conclusions, corresponding policy suggestions are proposed from the perspective of the government's top-level design, personnel training and introduction system, and marine intellectual property protection, to boost the high-quality development of Hainan's marine economy.
Color Matching Simulation of Ocean Landscape Decoration Pattern Based on Visual Communication

ABSTRACT Wang, J.; Liu, M. , and Li, W. , 2020. Color matching simulation of ocean landscape decoration pattern based on visual communication. In: Yang, D.F. and Wang, H. (eds.), Recent Advances in Marine Geology and Environmental Oceanography. Journal of Coastal Research, Special Issue No. 108, pp. 173–177. Coconut Creek (Florida), ISSN 0749-0208. Marine landscape design and visual communication have deep cross backgrounds. Marine landscape as a special tourism environment has a unique design scope. The connotation of marine landscape design is as a comprehensive marine visual language design and landscape design composite, to reinterpret the visual language and visual symbols, and reflect the visual symbols and the huge influence of visual language. In this paper, the color matching of marine landscape decoration pattern is optimized, which can effectively improve the design quality of marine landscapes. Ocean landscape based on visual communication, design, color, and decorative pattern optimization methods to match the color on the process is as follows. First, you need to set up corresponding to the color of the space and then, calculating chromaticity moments of the pixels in different connecting blocks on the basis of the Legendre polynomial calculation, use the core of the marine landscape decoration design color feature, extracting based on the distance between the different types of color clustering, and finally complete the optimization of marine landscape decoration design color matching. The simulation results show that the proposed method has obvious matching effects and greatly improves the quality of marine landscape design.
Exploring Influencing Factors of Seafood E-commerce Efficiency: Based on Panel Data from 2011 to 2018

ABSTRACT Shen, D. ; Yang, Y. , and Lu, J., 2020. Exploring influencing factors of seafood e-commerce efficiency: Based on panel data from 2011 to 2018. In: Yang, D.F. and Wang, H. (eds.), Recent Advances in Marine Geology and Environmental Oceanography. Journal of Coastal Research, Special Issue No. 108, pp. 322–326. Coconut Creek (Florida), ISSN 0749-0208. The authors explore the seafood e-commerce efficiency from 2011 to 2018 of nine coastal provinces in China by computing the Malmquist index. Then, the authors construct the dynamic panel data model to analyze the influencing factors of total factor productivity change. The result of the Malmquist index shows that the seafood e-commerce efficiency in the period 2011–2018 shows an increasing trend. Agglomeration, market size, and retail services are major driven forces to promote efficiency. Policy recommendations are presented based on empirical results.
Antigens of Mycobacterium tuberculosis Stimulate CXCR6+ Natural Killer Cells

Natural killer (NK) cells participate in immunity against several pathogens by exerting cytotoxic and cytokine-production activities. Some NK cell subsets also mediate recall responses that resemble memory of adaptive lymphocytes against antigenic and non-antigenic stimuli. The C-X-C motif chemokine receptor 6 (CXCR6) is crucial for the development and maintenance of memory-like responses in murine NK cells. In humans, several subsets of tissue-resident and circulating NK cells with different functional properties express CXCR6. However, the role of CXCR6+ NK cells in immunity against relevant human pathogens is unknown. Here, we addressed whether murine and human CXCR6+ NK cells respond to antigens of Mycobacterium tuberculosis (Mtb). For this purpose, we evaluated the immunophenotype of hepatic and splenic CXCR6+ NK cells in mice exposed to a cell-wall (CW) extract of Mtb strain H37Rv. Also, we characterized the expression of CXCR6 in peripheral NK cells from active pulmonary tuberculosis (ATB) patients, individuals with latent TB infection (LTBI), and healthy volunteer donors (HD). Furthermore, we evaluated the responses of CXCR6+ NK cells from HD, LTBI, and ATB subjects to the in vitro exposure to CW preparations of Mtb H37Rv and Mtb HN878. Our results showed that murine hepatic CXCR6+ NK cells expand in vivo after consecutive administrations of Mtb H37Rv CW to mice. Remarkably, pooled hepatic and splenic, but not isolated splenic NK cells from treated mice, enhance their cytokine production capacity after an in vitro re-challenge with H37Rv CW. In humans, CXCR6+ NK cells were barely detected in the peripheral blood, although slightly significative increments in the percentage of CXCR6+, CXCR6+CD49a−, CXCR6+CD49a+, and CXCR6+CD69+ NK cells were observed in ATB patients as compared to HD and LTBI individuals. In contrast, the expansion of CXCR6+CD49a− and CXCR6+CD69+ NK cells in response to the in vitro stimulation with Mtb H37Rv was higher in LTBI individuals than in ATB patients. Finally, we found that Mtb HN878 CW generates IFN-γ-producing CXCR6+CD49a+ NK cells. Our results demonstrate that antigens of both laboratory-adapted and clinical Mtb strains are stimulating factors for murine and human CXCR6+ NK cells. Future studies evaluating the role of CXCR6+ NK cells during TB are warranted.
A chronology of global air quality

Air pollution has been recognized as a threat to human health since the time of Hippocrates, ca 400 BC. Successive written accounts of air pollution occur in different countries through the following two millennia until measurements, from the eighteenth century onwards, show the growing scale of poor air quality in urban centres and close to industry, and the chemical characteristics of the gases and particulate matter. The industrial revolution accelerated both the magnitude of emissions of the primary pollutants and the geographical spread of contributing countries as highly polluted cities became the defining issue, culminating with the great smog of London in 1952. Europe and North America dominated emissions and suffered the majority of adverse effects until the latter decades of the twentieth century, by which time the transboundary issues of acid rain, forest decline and ground-level ozone became the main environmental and political air quality issues. As controls on emissions of sulfur and nitrogen oxides (SO2 and NOx) began to take effect in Europe and North America, emissions in East and South Asia grew strongly and dominated global emissions by the early years of the twenty-first century. The effects of air quality on human health had also returned to the top of the priorities by 2000 as new epidemiological evidence emerged. By this time, extensive networks of surface measurements and satellite remote sensing provided global measurements of both primary and secondary pollutants. Global emissions of SO2 and NOx peaked, respectively, in ca 1990 and 2018 and have since declined to 2020 as a result of widespread emission controls. By contrast, with a lack of actions to abate ammonia, global emissions have continued to grow. This article is part of a discussion meeting issue ‘Air quality, past present and future’.
Estimation of crystallinity in flyash-based zeolite-A using XRD and IR spectroscopy

Various processes have been developed for synthesis of zeolite -A from flyash (FAZ-A), which have been patented nationally and internationally. The processes developed include five different methodologies with variations in pretreatment steps, sodium aluminate addition, etc. as a function of structure develo pment and exchange capacity. Infrared (IR) spectroscopy has been used to study the framework structure of zeolites and also estimate their crystallinity. A systematic i nvestigation of the framework structures have been carried out in the range of 400–4000 cm –1 . Investigations were based on the assignment of IR band to ce rtain structural groups in the various zeolitic framework structures. The per cent crystallinity of FAZ -A samples has been ascertained by comparing the ratio of intensity of the peak at 560 and 480 cm –1 with the corresponding ratio for a standard sample. The per cent crystallinity of FAZ-A is calculated using standard procedure. Results of crystallinity obtained by IR and X-ray diffraction (XRD) methods are comparable and range between 85 and 100%. Investigation using IR is found to be good for estimating crystallinity and structure elucidation and is complementary to XRD.
The effects of dried pistachio (Pistachio vera L.) by-product addition on corn silage fermentation and in vitro methane production

ABSTRACT The objective of this study was to determine the effect of adding different levels of pistachio by-product (PB) on the fermentation quality, nutritive value and in vitro methane (CH4) production of corn silage. For this purpose, silages were prepared in the 1.5 l glass jars by adding with 2%, 4%, 6%, 8% and 10% pistachio PB (as a dry matter basis). The results showed that addition of 6%, 8% and 10% pistachio PB levels decreased (P < 0.05) silage acetic acid content. Increment of pistachio PB level increased (P < 0.05) silage propionic acid content, but it decreased (P < 0.05) ammonia nitrogen values. Addition of all levels of pistachio PB decreased (P < 0.05) gas production (from 251.70 to 196.76 ml/g dry matter (DM)), in vitro organic matter digestibility (from 70.26% to 61.62%) and metabolizable energy (from 9.69% to 8.27 MJ/kg DM) values. Similarly, increment-level pistachio PB decreased (P < 0.05) of in vitro methane production level. As a result, pistachio PB might have a potential usage value as silage additive when undesired ruminal methane production is aimed to be suppressed by ruminant.
Phylogenetic analysis of Groundnut ringspot virus isolates from peanut and identification of potential thrips vectors in peanut crop in Argentina

SUMMARY Groundnut ringspot virus (GRSV), genus Tospovirus, is a thrips-transmitted virus infecting peanuts (Arachis hypogaea L.) in Cordoba province, Argentina. Fourteen viral isolates were recovered from Tospovirus-like symptomatic plants from different peanut fields. Viral isolates as GRSV were identified by serological and molecular tests. Nucleotide and derived amino acid sequence analyses of the nucleocapsid (N) gene indicated a high degree of identity between the GRSV peanut isolates, indicating that there is no molecular variability in the N gene of the GRSV that infects peanuts in the cropping area of Cordoba. In this study, we determined the presence of thrips species in the crop, which can potentially transmit the virus. Thrips were observed in all the evaluated peanut fields. Frankliniella schultzei was the most frequently identified species followed by Caliothrips phaseoli and Frankliniella occidentalis. This work reports the presence of F. schultzei and F. occidentalis in peanuts in Argentina for the first time. These results along with the high degree of similarity between the GRSV peanut isolates suggest that the virus could be transmitted by F. schultzei, which has been cited as its most efficient vector.
Innate and Environmental Dispersal of Individual Vertebrates

Little is known about the rates of dispersal of the young of wild populations of vertebrates, because it is difficult to recover marked individuals after they have dispersed to breed elsewhere. Nevertheless, growing evidence suggests that the observed dispersal patterns may be governed by the laws of heredity as well as being influenced by population pressure. Dispersal of an individual vertebrate is the movement the animal makes from its point of origin to the place where it reproduces or would have reproduced if it had survived and found a mate. The significant role of an individual's dispersal is the greatest distance its
Tribological Characteristics of Protected Silver Nanoparticles in Oil

In recent years, there has been considerable interest in employing dispersed solid particles in the nanoscale range to enhance the friction and wear characteristics of liquid lubricants. Previous studies have suggested that tiny colloidal particles, under tribochemical conditions, deposit on rubbing surfaces influencing tribological characteristics of the contact. This article presents a study of the tribological behavior of stabilized silver nanoparticles dispersed in n-hexadecane. Friction and wear measurements are combined to investigate the extent to which colloidal solid particles influence a lubricated contact. It is shown that the silver nanoparticles studied contribute to reduce friction and wear only in the thin film regime. Nanoparticles help to reduce friction and wear down to a certain concentration value. Higher concentrations of nanoparticles do not bring any further contribution to reduce friction or wear, suggesting the existence of an optimum concentration of nanoparticles.
Drift distance of macroinvertebrates throughout summer in headwater tributaries of the Calapooia River

Drifting invertebrates from small headwater streams are a food subsidy for fishes and other downstream consumers in larger streams. This subsidy can become especially important for stream fishes during summer due to high metabolic demand caused by elevated water temperatures. The source length in small streams contributing these drifting invertebrates to fish bearing habitat has not been established. We conducted an experiment to determine if summer drift delivered by headwater streams to larger channels is influenced by contributions originating more than 100 m upstream. We conducted this experiment on tributaries of the Calapooia River, Oregon, USA. We blocked drift with 250 μm mesh nets in three streams 100 m upstream of our sample nets continuously for 48 d. We also sampled five streams without blocking nets. Four 24 h samples of drift were collected prior to the placement of blocking nets and every two weeks afterwards at each stream. Overall mean abundance and mean biomass of drift did not differ between blocked and unblocked streams for any sampling period. There was a temporal trend at all sites of declining invertebrate abundance and biomass. We found no treatment effect for any of the most common insect orders or for the 16 genera that comprised at least 1% of the total organisms captured. The majority of invertebrate drift is of local origin in headwater streams during summer baseflow.
Cytogenetic and Molecular Diagnostics of XX/XY Chimerism in Cattle, Sheep, and Goats – A Review

Abstract Animal cell chimerism denotes the presence of two or more cell lines of different genetic origin. The most common form of chimerism, which occurs spontaneously in mammals, is the presence of two or more cell populations in animals derived from dizygotic twin or multiple pregnancies. The aim of this review is to present extensive information on XX/XY chimerism in cattle, sheep and goats from the Bovidae family. Additionally, it will discuss a methodology for a quick and accurate diagnosis of cell chimerism and make an analysis of cells obtained from gonads of animals derived from twin pregnancies which underwent an exchange of hematopoietic tissue as a result of anastomoses. The studies reviewed here led the authors to conclude that XX/XY chimerism is generally undesirable in livestock breeding. Females (freemartins) are infertile, whereas in male carriers of chimerism, the impact of this abnormality on sperm parameters is still under discussion, therefore every case of different-sex twin or multiple births should be analyzed individually.
