Tendon refers to a band of tough, regularly arranged and connective tissue connecting muscle and bone, transferring strength from muscle to bone, and enabling articular stability and movement. The limitations of natural tendon grafts motivate the scaffold-based tissue engineering (TE) approaches, which aim to build patient-specific biological substitutes that can repair the damaged or diseased tissues. Advances in engineering and knowledge of chemistry and biology have brought forth numerous fiber-based technologies, including electrospinning, electrohydrodynamic jet printing, electrochemical alignment technique and other fiber-assembly technologies, which enable the fabrication of tendon tissue structure in three-dimension...

The electronic textile area has gained considerable attention due to its implementation of wearable devices, and soft sensors are the main components of these systems. In this paper, a new sensor design is presented to create stretchable, capacitance-based strain sensors for human motion tracking. This involves the use of stretchable, conductive-knit fabric within the silicone elastomer matrix, as interdigitated electrodes. While conductive fabric creates a secure conductive network for electrodes, a silicone-based matrix provides encapsulation and dimensional-stability to the structure...

In Denmark, we have set up a program to establish a nationwide infrastructure for Patient Reported Outcome (PRO) questionnaires. The effort is divided into an IT infrastructure part and a questionnaire development part. This paper describes how development and evaluation are closely knit together in the two tracks, as complexity is high in the PRO field and IT infrastructure, legal issues, various clinical workflows and the numerous stakeholders have to be taken into account concurrently. In the design process, we have thus used a participatory design approach to ensure a high level of active stakeholder involvement and capability of addressing all the relevant issues...

Polyproteins, individual protein units joined covalently in tandem, have been evolved as a promising tool for measuring the dynamic folding of bio-macromolecules in single-molecule force spectroscopy. However, the synthetic routes of preparing polyproteins have been a bottleneck, and urge for developing in-vitro methods to knit individual protein units covalently into polyprotein. Employing two enzymes of orthogonal functionalities periodically in sequence, we synthesized monodispersed polyproteins on a solid surface...

Burkholderia pseudomallei is the causative agent of melioidosis and regarded as a bioterrorism threat. It can adapt to the nutrient-limited environment as the bacteria can survive in triple distilled water for 16 years. Moreover, B. pseudomallei exhibits intrinsic resistance to diverse groups of antibiotics in particular while growing in biofilms. Recently, nutrient-limited condition influenced both biofilm formation and ceftazidime (CAZ) tolerance of B. pseudomallei were found. However, there is no information about how nutrient-limitation together with antibiotics used in melioidosis treatment affects the structure of the biofilm produced by B...

Parabens are used as antimicrobial preservatives in food, cosmetic products and pharmaceuticals regardless of their endocrine disrupting effect. In this study, highly selective molecular imprinted polymers (MIPs) were synthesized in submicron-sizes and converted to an SPME fiber coating through electrospinning process in order to determine parabens in water samples. Conversion of MIP to a fiber is achieved via creation of spacial knitting around MIP by polystyrene. The selectivity and extraction ability of the fibers were compared with the commercial fibers and the corresponding non-imprinted polymer (NIP) coated fiber...

Body-mountable electronics and electronically active garments are the future of portable, interactive devices. However, wearable devices and electronic garments are demanding technology platforms because of the large, varied mechanical stresses to which they are routinely subjected, which can easily abrade or damage microelectronic components and electronic interconnects. Furthermore, aesthetics and tactile perception (or feel) can make or break a nascent wearable technology, irrespective of device metrics...

: Cellular morphology reflects biologic behavior and activity of the tissue and of the organ also reflects the genetic and molecular biology of the cells themselves. This intermediary position places examination of the cell in a key role to our understanding of the innumerable processes that affect this closely knit chain, from molecules to host. A large volume of the cell is occupied by organelles that come in a variety of shapes and sizes. Organelles are dynamic to maintain homeostasis and adjust to the various functions of the cell...

Neural stem and progenitor cells continue to generate new neurons in particular regions of the brain during adulthood. One of these neurogenic regions is the dentate gyrus (DG) of the hippocampus, which plays an important role in cognition and emotion. By exploiting this innate neuronal regeneration mechanism in the DG, new technologies have the potential to promote resistance to or recovery from brain dysfunction or degeneration. However, a deeper understanding of how adult DG neurogenesis is regulated by factors such as sleep and epigenetic modifications of gene expression could lead to further breakthroughs in the clinical application of neural stem and progenitor cells...

Development of a small-diameter artificial vascular graft is urgent because existing materials often occlude within a short time. We have shown that small-diameter vascular graft using Bombyx mori silk fibroin is a potential candidate. Silk fibroin grafts are fabricated by coating silk fibroin on the knit tube prepared from silk fibroin fibers. However, there is a serious problem that the coated silk fibroin portion hardens when alcohol is used for insolubilization of the coated silk fibroin. This hardening prevents the desired biodegradation of the coated silk fibroin...
