    Neighborhood Disadvantage and Self-Esteem—Do Socioeconomic and Relational Resources Matter?

    Joongbaeck Kim1, Manacy Pai2,*

    International Journal of Mental Health Promotion, Vol.24, No.3, pp. 311-329, 2022, DOI:10.32604/ijmhp.2022.017555

    Abstract Extensive research suggests that living in a socioeconomically disadvantaged neighborhood is associated with poor mental health. Few studies, however, have examined (1) whether neighborhood disadvantage is associated with residents’ self-esteem; and (2) the extent to which individual-level socioeconomic resources such as income and education, and relational resources such as marriage and social support moderate the association between neighborhood disadvantage and self-esteem. This study employs data from the Americans’ Changing Lives panel survey (hereafter ACL), a 15-year panel study of the U.S. adult population ages 25 and older in original sample. Because hierarchical linear model was… More >

    Tuning mesenchymal stem cell secretome therapeutic potential through mechanotransduction


    BIOCELL, Vol.46, No.6, pp. 1375-1381, 2022, DOI:10.32604/biocell.2022.019681

    Abstract Mesenchymal stem cells (MSCs) and their byproducts have been widely validated as potential therapeutic products for regenerative medicine. The therapeutic effects result mainly from the paracrine activity of MSCs, which consists of the secretion of bioactive molecules, whether dispersed in medium conditioned by cell culture or encapsulated in extracellular vesicles. The composition of the MSC secretome, which represents the set of these secreted cellular products, is crucial for the performance of the desired therapeutic functions. Different cell culture strategies have been employed to adjust the secretome composition of MSCs to obtain the best therapeutic responses More >

    Precise tissue bioengineering and niches of mesenchymal stem cells: Their size and hierarchy matter


    BIOCELL, Vol.46, No.6, pp. 1365-1373, 2022, DOI:10.32604/biocell.2022.018917

    Abstract Stem cell microterritories (niches), as a specialized part of the extracellular matrix (ECM), are considered an important target and tool for the development of new materials, medical implants, and devices. However, tissue bioengineering products that have stem cell niches of known size on the surface or in the bulk structure of artificial materials are practically unknown. This brief review attempts to draw attention to the problematic aspects of niches as specific parts of the ECM, such as their hierarchy and size for mesenchymal stromal/stem cells (MSCs). These parameters arise directly from numerous definitions of stem More >

    CMC-Computers, Materials & Continua, Vol.71, No.1, pp. 1677-1693, 2022, DOI:10.32604/cmc.2022.022227

    Abstract This paper introduces a decagonal C-shaped complementary split-ring resonator (CSRR) textile-based metamaterial (MTM). The overall size of the proposed sub-wavelength MTM unit cell is 0.28λ0 × 0.255λ0 at 3 GHz. Its stopband behaviour was first studied prior analysing the negative index properties of the proposed MTM. It is worth noting that in this work a unique way the experiments were completed. For both simulations and measurements, the proposed MTM exhibited negative-permittivity and negative-refractive index characteristics with an average bandwidth of more than 3 GHz (considering 1.7 to 8.2 GHz as the measurements were carried out within this range).… More >

    Neha Srivastava1,*, Akshay Shrivastav2, Rajeev Singh3, Mohammed Abohashrh4, K. R. Srivastava1, Safia Irfan5, Manish Srivastava1, P. K. Mishra1, Vijai Kumar Gupta6, Vijay Kumar Thakur6,*

    Journal of Renewable Materials, Vol.9, No.4, pp. 615-636, 2021, DOI:10.32604/jrm.2021.014374

    Abstract Increased environmental pollution due to the organic wastes over the world is one of the most burning issues. These organic wastes lie under the category of biodegradable waste and can be effectively degraded from their complex compound into simple one by the action of microbes or other living organisms. Moreover, lignocellulosic biomass is a major part of the biodegradable waste and belongs to the group of renewable energy source, which can be very effective for bioenergy production. Biomasses are made up of different compounds such as cellulose, hemicelluloses, lignin and protein. Apart from these components, More >

    Florin Valentin Leuciuc1,2,*, Maria Daniela Craciun1,2, Iulian Stefan Holubiac1, Mazin Abed Mohammed3, Karrar Hameed Abdulkareem4, Gheorghe Pricop1,2

    CMC-Computers, Materials & Continua, Vol.67, No.2, pp. 2601-2617, 2021, DOI:10.32604/cmc.2021.014863

    Abstract Identifying patterns, recognition systems, prediction methods, and detection methods is a major challenge in solving different medical issues. Few categories of devices for personal and professional assessment of body composition are available. Bioelectrical impedance analyzer is a simple, safe, affordable, mobile, non-invasive, and less expensive alternative device for body composition assessment. Identifying the body composition pattern of different groups with varying age and gender is a major challenge in defining an optimal level because of the body shape, body mass, energy requirements, physical fitness, health status, and metabolic profile. Thus, this research aims to identify… More >

    CMC-Computers, Materials & Continua, Vol.67, No.1, pp. 321-336, 2021, DOI:10.32604/cmc.2021.014102

    Abstract Internet of Everything (IoE) indicates a fantastic vision of the future, where everything is connected to the internet, providing intelligent services and facilitating decision making. IoE is the collection of static and moving objects able to coordinate and communicate with each other. The moving objects may consist of ground segments and flying segments. The speed of flying segment e.g., Unmanned Ariel Vehicles (UAVs) may high as compared to ground segment objects. The topology changes occur very frequently due to high speed nature of objects in UAV-enabled IoE (Ue-IoE). The routing maintenance overhead may increase when… More >

    Differential Catalysis of Depolymerisation and Dehydration Reactions: Producing Furfural from Plant Biomass

    Nikolajs Vedernikovs*

    Journal of Renewable Materials, Vol.8, No.6, pp. 661-674, 2020, DOI:10.32604/jrm.2020.09274

    Abstract The main principles of the technological realisation of the furfural obtaining process have been formulated by Ricard [1]. Based on his recommendations, all investigators proceeded from the assumption that the depolymerisation of pentosans and the dehydration of pentoses in the one-step production of furfural from raw plant material must be accelerated with diluted catalyst solutions. According to this theory, uniform impregnation of the raw material with a catalyst solution is considered necessary. The reduction in the amount of the catalyst solution down to 30–40% of the mass of the dry raw material, suggested by Miner… More >

    Masaki Sato1, Kei Inai1,2, Mikiko Shimizu1, Hisashi Sugiyama1, Toshio Nakanishi2

    Congenital Heart Disease, Vol.14, No.2, pp. 167-175, 2019, DOI:10.1111/chd.12683

    Abstract Objective: The recognition of fluid retention is critical in treating heart failure (HF). Bioelectrical impedance analysis (BIA) is a well-known noninvasive method; however, data on its role in managing patients with congenital heart disease (CHD) are limited. Here, we aimed to clarify the correlation between BIA and HF severity as well as the prognostic value of BIA in adult patients with CHD.
    Design: This prospective single-center study included 170 patients with CHD admitted between 2013 and 2015. We evaluated BIA parameters (intra- and extracellular water, protein, and mineral levels, edema index [EI, extracellular water-to-total body water ratio]),… More >
