Hollow Fiber and Nanofiber Membranes in Bioartificial Liver and Neuronal Tissue Engineering.

Cells Tissues Organs 2021 Apr 13:1-30. Epub 2021 Apr 13.

Institute on Membrane Technology, National Research Council of Italy, CNR-ITM, Rende, Italy.

To date, the creation of biomimetic devices for the regeneration and repair of injured or diseased tissues and organs remains a crucial challenge in tissue engineering. Membrane technology offers advanced approaches to realize multifunctional tools with permissive environments well-controlled at molecular level for the development of functional tissues and organs. Membranes in fiber configuration with precisely controlled, tunable topography, and physical, biochemical, and mechanical cues, can direct and control the function of different kinds of cells toward the recovery from disorders and injuries.

Taurine reduction associated with heart dysfunction after real-world PM exposure in aged mice.

Sci Total Environ 2021 Apr 5;782:146866. Epub 2021 Apr 5.

Guangdong Key Laboratory of Environmental Catalysis and Health Risk Control, Guangdong-Hong Kong-Macao Joint Laboratory for Contaminants Exposure and Health, School of Environmental Science and Engineering, University of Technology, Guangzhou 510006, PR China; State Key Laboratory of Environmental and Biological Analysis, Department of Chemistry, Hong Kong Baptist University, Hong Kong, China. Electronic address:

Ambient PM has been proved to be an independent risk factor for cardiovascular diseases; however, little information is available on the age-dependent effects of PM on the cardiovascular system and the underlying mechanisms following chronic exposure. In this study, multi-aged mice were exposed to PM via the newly developed real-ambient PM exposure system to investigate age-related effects on the heart after long-term exposure. First, the chemical and physical properties of PM used in the exposure system were analyzed. Read More

The Lanata trichome mutation increases stomatal conductance and reduces leaf temperature in tomato.

J Plant Physiol 2021 Apr 6;260:153413. Epub 2021 Apr 6.

Departamento de Biologia Vegetal, Universidade Federal de Viçosa, CEP 36570-900, Viçosa, MG, Brazil. Electronic address:

Trichomes are epidermal structures with a large variety of ecological functions and economic applications. Glandular trichomes produce a rich repertoire of secondary metabolites, whereas non-glandular trichomes create a physical barrier on the epidermis: both operate in tandem against biotic and abiotic stressors. A deeper understanding of trichome development and function would enable the breeding of more resilient crops. Read More

Chitosan/alginate/hyaluronic acid polyelectrolyte composite sponges crosslinked with genipin for wound dressing application.

Int J Biol Macromol 2021 Apr 10. Epub 2021 Apr 10.

Key Laboratory of Industrial Microbiology, Ministry of Education, College of Biotechnology, Tianjin University of Science and Technology, China International Science and Technology Cooperation Base of Food Nutrition/Safety and Medicinal Chemistry, Tianjin 300457, PR China; Institute of Medical Support Technology, Academy of Military Sciences, Tianjin 300161, PR China. Electronic address:

Wound dressing composed of polyelectrolyte complexes (PECs), based on chitosan/alginate/hyaluronic acid (CS/ALG/HYA) crosslinked by genipin, was prepared by freeze-dried molding. Genipin as excellent natural biological crosslinker was chose for high biocompatibility and improving mechanical properties of materials. The CS/ALG/HYA sponges (CAHSs) were characterized by FTIR, XRD, DSC and SEM. Read More

Wetting Dynamics of a Lipid Monolayer.

Langmuir 2021 Apr 13. Epub 2021 Apr 13.

Department of Physics, Hong Kong University of Science and Technology, Clear Water Bay, Kowloon, Hong Kong, China.

Direct measurement and control of the dynamic wetting properties of a lipid-coated water-air interface over a wide range of surface tension variations have many important applications. However, the wetting dynamics of the interface near its partial-to-complete wetting transition has not been fully understood. Here, we report a systematic study of the wetting dynamics of a lipid-coated water-air interface around a thin glass fiber of diameter 1-5 μm and length 100-300 μm. Read More

The Hausa Back Beliefs Questionnaire: Translation, cross-cultural adaptation and psychometric assessment in mixed urban and rural Nigerian populations with chronic low back pain.

PLoS One 2021 13;16(4):e0249370. Epub 2021 Apr 13.

Faculty of Allied Health Sciences, Department of Physiotherapy, College of Health Sciences, Bayero University Kano, Kano, Kano State, Nigeria.

Introduction: Negative attitudes and beliefs about low back pain (LBP) can lead to reduced function and activity and consequently disability. One self-report measure that can be used to assess these negative attitudes and beliefs and to determine their predictive nature is the Back Beliefs Questionnaire (BBQ). This study aimed to translate and cross-culturally adapt the BBQ into Hausa and assess its psychometric properties in mixed urban and rural Nigerian populations with chronic LBP. Read More
