RSM based optimization of nutritional conditions for cellulase mediated Saccharification by Bacillus cereus
Journal of Biological Engineering - Tập 12 - Trang 1-10 - 2018
Fouzia Tabssum, Muhammad Irfan, Hafiz Abdullah Shakir, Javed Iqbal Qazi
Cellulases are enzyme which have potential applications in various industries. Researchers are looking for potential cellulolytic bacterial strains for industrial exploitation. In this investigation, cellulase production of Bacillus cereus was explored while attacking poplar twigs. The bacterium was isolated from the gut of freshwater fish, Labeo rohita and identified by 16S rRNA gene sequencing t...... hiện toàn bộ
Discrimination between the effects of pulsed electrical stimulation and electrochemically conditioned medium on human osteoblasts
Journal of Biological Engineering - Tập 17 - Trang 1-18 - 2023
Meike Bielfeldt, Kai Budde-Sagert, Nikolai Weis, Maren Buenning, Susanne Staehlke, Julius Zimmermann, Nils Arbeiter, Sahba Mobini, María Ujué González, Henrike Rebl, Adelinde Uhrmacher, Ursula van Rienen, Barbara Nebe
Electrical stimulation is used for enhanced bone fracture healing. Electrochemical processes occur during the electrical stimulation at the electrodes and influence cellular reactions. Our approach aimed to distinguish between electrochemical and electric field effects on osteoblast-like MG-63 cells. We applied 20 Hz biphasic pulses via platinum electrodes for 2 h. The electrical stimulation of th...... hiện toàn bộ
Advances in the application of Mxene nanoparticles in wound healing
Journal of Biological Engineering - Tập 17 Số 1
Chengzhi Liang, Jie He, Yuan Chen, Guoming Liu, Chengdong Zhang, Qi Zhang, Chen Fu, Yanling Hu
AbstractSkin is the largest organ of the human body. It plays a vital role as the body’s first barrier: stopping chemical, radiological damage and microbial invasion. The importance of skin to the human body can never be overstated. Delayed wound healing after a skin injury has become a huge challenge in healthcare. In some situations, this can have very serious an...... hiện toàn bộ
The LINC complex, mechanotransduction, and mesenchymal stem cell function and fate
Journal of Biological Engineering - Tập 13 - Trang 1-12 - 2019
Tasneem Bouzid, Eunju Kim, Brandon D. Riehl, Amir Monemian Esfahani, Jordan Rosenbohm, Ruiguo Yang, Bin Duan, Jung Yul Lim
Mesenchymal stem cells (MSCs) show tremendous promise as a cell source for tissue engineering and regenerative medicine, and are understood to be mechanosensitive to external mechanical environments. In recent years, increasing evidence points to nuclear envelope proteins as a key player in sensing and relaying mechanical signals in MSCs to modulate cellular form, function, and differentiation. Of...... hiện toàn bộ
Formaldehyde formation in the glycine cleavage system and its use for an aldolase-based biosynthesis of 1,3-propanediol
Journal of Biological Engineering - - 2020
Yingying Xu, Hao Meng, Jie Ren, An‐Ping Zeng
AbstractGlycine cleavage system (GCS) occupies a key position in one-carbon (C1) metabolic pathway and receives great attention for the use of C1 carbons like formate and CO2 via synthetic biology. In this work, we demonstrate that formaldehyde exists as a substantial byproduct of the GCS reaction cycle. Three causes are identified for its form...... hiện toàn bộ
A multiplexed magnetic tweezer with precision particle tracking and bi-directional force control
Journal of Biological Engineering - Tập 11 - Trang 1-13 - 2017
Keith C. Johnson, Emilie Clemmens, Hani Mahmoud, Robin Kirkpatrick, Juan C. Vizcarra, Wendy E. Thomas
In the past two decades, methods have been developed to measure the mechanical properties of single biomolecules. One of these methods, Magnetic tweezers, is amenable to acquisition of data on many single molecules simultaneously, but to take full advantage of this "multiplexing" ability, it is necessary to simultaneously incorporate many capabilities that have been only demonstrated separately. O...... hiện toàn bộ
Microbial inactivation and shelf life of apple juice treated with high pressure carbon dioxide
Journal of Biological Engineering - Tập 3 - Trang 1-9 - 2009
Giovanna Ferrentino, Mariacarmela Bruno, Giovanna Ferrari, Massimo Poletto, Murat O Balaban
Apple juice prepared from 'Annurca' apple puree was treated with a HPCD batch system. The pH, °Brix, color parameters and microbial load of the treated apple juice were compared with those of thermally processed juice. Thermal processes were carried out at 35, 50, 65, 85°C and treatment times ranging between 10 and 140 minutes. Microbial inactivation kinetics indicated that 5-log reduction of natu...... hiện toàn bộ
Fabrication of chitosan-polyvinyl alcohol and silk electrospun fiber seeded with differentiated keratinocyte for skin tissue regeneration in animal wound model
Journal of Biological Engineering - Tập 14 - Trang 1-14 - 2020
Afshin Fathi, Mehdi Khanmohammadi, Arash Goodarzi, Lale Foroutani, Zahra Taherian Mobarakeh, Jamileh Saremi, Zohreh Arabpour, Jafar Ai
Hybrid fibrous mat containing cell interactive molecules offers the ability to deliver the cells and drugs in wound bed, which will help to achieve a high therapeutic treatment. In this study, a co-electrospun hybrid of polyvinyl alcohol (PVA), chitosan (Ch) and silk fibrous mat was developed and their wound healing potential by localizing bone marrow mesenchymal stem cells (MSCs)-derived keratino...... hiện toàn bộ
