Evaluation of basophil activation caused by transgenic rice seeds expressing whole T cell epitopes of the major Japanese cedar pollen allergens

Shinya Takaishi, Saburo Saito, Minori Kamada, Nobuyoshi Otori, more

Clinical and Translational Allergy > 2019 > 9 > 1 > 1-8

Background Japanese cedar (JC) pollinosis is a serious type I allergic disease in Japan. Although subcutaneous immunotherapy and sublingual immunotherapy have been applied to treat JC pollinosis, high doses of allergens may cause IgE-mediated allergic reactions. The transgenic rice seeds that contain genetically modified Cry j 1 and Cry j 2, the two major allergens of JC pollen, have been developed...

Production of enantiopure (R)- or (S)-2-hydroxy-4-(methylthio)butanoic acid by multi-enzyme cascades

Can Zhang, Wei Song, Jia Liu, Xiulai Chen, more

Bioresources and Bioprocessing > 2019 > 6 > 1 > 1-12

(R)- or (S)-2-Hydroxy-4-(methylthio)butanoic acid (HMTBA) is used as a poultry nutritional supplement and to treat renal failure disease. Herein, we report an artificially designed biocatalytic cascade process, which uses l-methionine to synthesize (R)- or (S)-HMTBA. This biocatalysis cascade comprises a basic module and two different extender modules and operates in a modular assembly manner. The...

Who is informed and who uninformed? Addressing the legal barriers to progress in dementia research and care

Jiska Cohen-Mansfield

Israel Journal of Health Policy Research > 2019 > 8 > 1 > 1-8

Conduct of research is an essential tool for the evaluation and improvement of health services. In Israel, research on persons with dementia is very limited, with the largest portion of such research involving a few surveys and examining risk factors for dementia. Very few studies describe clinical research, and those that do either include participants at early stages of dementia, or rely completely...

Mini research projects as a mechanism to improve the quality of dementia care

Hava Golander

Israel Journal of Health Policy Research > 2019 > 8 > 1 > 1-7

Several models have been proposed to connect academia and practice in order to improve long-term care. In this paper we propose and describe the “Mini-Research Group” as an alternative model of such collaboration. The formation of mini-research groups was the unplanned by-product of a longitudinal action research project headed by the late Prof. Rebecca Bergman, a prominent nursing leader from the...

Patterns of Pollen Dispersal in an Invasive Population of Solanum rostratum (Solanaceae) in China

L. J. Zhang, A. R. Lou

Russian Journal of Ecology > 2018 > 49 > 6 > 517-523

Paternity analysis, carried out on 13 microsatellite loci, was used to investigate pollen dispersal and mating patterns in an invasive population of Solanum rostratum in China. We determined a high outcrossing rate (0.81 ± 0.02) and found that all 174 offspring for which the father could be identified were outcross progeny. The mean pollen dispersal distance was 13.66 m (range 0.41–71.67 m); however,...

Tancredo Augusto Feitosa de Souza, Susana Rodriguez-Echeverria, Helena Freitas, Leonaldo Alves de Andrade, more

Russian Journal of Ecology > 2018 > 49 > 6 > 500-506

Parkinsonia aculeata and Prosopis juliflora are two of the most problematic invasive plant species in the Brazilian tropical seasonal dry forest, but the mechanisms driving the biological invasion of this ecosystem is virtually unknown. This study assessed the role of arbuscular mycorrhizal symbiosis, in particular of Funneliformis mosseae, on the biological invasion process by P. aculeata and P. juliflora...

Russian Journal of Ecology > 2018 > 49 > 6 > 543-547

The effects of landscape heterogeneity on changes in the common shrew population were researched. Multiyear (1987–2017) time series data on species abundance in the plain and piedmont areas of the Pechora-Ilych State Nature Biosphere Reserve have been analyzed using the Fourier spectral analysis method. A cyclic component of three years and another one of lower value at five years were identified...

E. I. Ponomarev, E. G. Shvetsov, V. I. Kharuk

Russian Journal of Ecology > 2018 > 49 > 6 > 492-499

A method for estimating direct wildfire emissions that considers fire intensity based on infrared radiation data from the Terra/MODIS satellite is proposed. In Siberia, we experimentally established that low intensity fires cover 47 ± 13% of the total area; that with moderate intensity, 42 ± 10%; and that with high-intensity, 10 ± 6%. The average value of wildfire emissions in Siberia is estimated...

Targeted delivery of 20(S)-ginsenoside Rg3-based polypeptide nanoparticles to treat colon cancer

Renna Qiu, Feng Qian, Xiaofeng Wang, Hongjun Li, more

Biomedical Microdevices > 2019 > 21 > 1 > 1-13

Colorectal cancer (CRC) is a major malignancy characterized by a high metastasis rate. Systematic chemotherapy is important for patients with advanced CRC. However, many limitations (e.g., side effects to normal organs, shorter circulation time, and unsatisfactory tumor inhibition results) of traditional chemotherapy restrict its further application. Thus, it is necessary to find a method to overcome...

Physical activity-related health and economic benefits of building walkable neighbourhoods: a modelled comparison between brownfield and greenfield developments

Belén Zapata-Diomedi, Claire Boulangé, Billie Giles-Corti, Kath Phelan, more

International Journal of Behavioral Nutrition and Physical Activity > 2019 > 16 > 1 > 1-12

Background A consensus is emerging in the literature that urban form can impact health by either facilitating or deterring physical activity (PA). However, there is a lack of evidence measuring population health and the economic benefits relating to alternative urban forms. We examined the issue of housing people within two distinct types of urban development forms: a medium-density brownfield development...
