... Cardiac patch has been proposed as an alternative therapeutic tissue engineering strategy to treat damaged heart for patients who survive the acute myocardial infarction (MI). To that end, studies have focused on designing an ideal cardiac patch assisting myocardium to repair itself. The engineering of three dimensional (3 D) anisotropic knitted scaffolds could be an efficient and effective strate ...
... In this study, a three-dimensional composite scaffold is proposed consisting of polylactic acid and spray dried glass-ceramic microparticles (SGCMs). The compositional and structural characterization showed that the obtained spray dried powder formed as glass-ceramic (GC) with a completely interconnected porosity structure. Before direct printing of scaffolds, the rheological behavior of polylacti ...
... Guided tissue regeneration (GTR) is the main therapeutic method for periodontal tissue regeneration. The key to the GTR strategy is the membrane which can assist the reconstruction of bone tissue in the periodontal defect and prevent the migration of epithelium and fibroblasts to the defect. However, the existing periodontal membrane cannot effectively promote periodontal tissue regeneration due t ...

Abstract:
... Although triple-negative breast cancer (TNBC) accounts for only 15% of breast cancer cases, it is associated with a high relapse rate and poor outcome after standard treatment. Currently, the effective drugs and treatment strategies for TNBC remain limited, and thus, developing effective treatments for TNBC is pressing. Several studies have demonstrated that both chalcone and syringaldehyde have a ...
... Amniotic membrane (AM) has been utilized as a wound dressing extensively. Given the importance of oxygen in wound healing, here we have reported the fabrication and characterization of an oxygen-generating wound dressing based on AM. This construct was composed of H₂O₂-loaded polylactic acid (PLA) microparticles embedded within a chitosan/β-glycerophosphate (β-GP) thermosensitive hydrogel covered ...
... SARS-CoV-2 is the RNA virus responsible for COVID-19, the prognosis of which has been found to be slightly worse in men. The present study aimed to analyze the expression of different mRNAs and their regulatory molecules (miRNAs and lncRNAs) to consider the potential existence of sex-specific expression patterns and COVID-19 susceptibility using bioinformatics analysis. The binding sites of all hu ...
... Cholinergic anti-inflammatory pathway (CAP) describes a neuronal-inflammatory reflex centered on systemic cytokine regulation by α7 nicotinic acetylcholine receptor (α7nAChR) activation of spleen-residue macrophage. However, the CAP mechanism attenuating distal tissue inflammation, inducing a low level of systemic inflammation, is lesser known. In this study, we hypothesized that CAP regulates mon ...
... We developed a composite wound dressing that provides multifunctional wound care. Alginate and polycaprolactone (PCL) were coelectrospun as composite fibers. Highly absorbent alginate provided a moist environment for wounds and PCL increased cell adhesion. Silver nanoparticles embedded in PCL fibers for long-term release inhibited the growth of microorganisms. In addition, plasmid DNA encoding pla ...
... Triple-negative breast cancer has an aggressive clinical course and its treatment has been challenging due to high metastatic risk. Molecular targets have been sought to provide better strategies for this type of cancer. Integrins are cell adhesion receptors involved in tumor progression and α₂β₁ integrin, a collagen receptor, has a key role in breast metastasis. Disintegrins, a family of proteins ...
... Integrins, a family of cell adhesion transmembrane receptors, mediate cell adhesion, migration, proliferation, apoptosis, and phagocytosis. In the present study, an integrin ChIntα 4 from Crassostrea hongkongensis was characterized to investigate its role in defensing against pathogenic bacterium Vibrio alginolyticus. The full-length cDNA sequence of ChIntα 4 was 3572 bp with an open reading frame ...

... Bacterial cells have the ability to form biofilm onto the surfaces of food matrixes and on food processing equipment, leading to a source of food contamination posing serious health implications. Therefore, our study aimed to determine the effect of Eruca sativa Miller (E. sativa) crude extract against biofilms of food-borne bacteria along with in silico approaches to investigate adhesion proteins ...
... The antibacterial and antibiofilm activity of essential oil of clove against Listeria monocytogenes and Salmonella Enteritidis were investigated. The chemical composition of the oil was characterized by gas chromatography–mass spectrometry. Stock solution of the essential oil of clove was prepared in 95% (v/v) ethanol (EOC). The antibacterial assays were performed by disk diffusion assay and minim ...
... Bladder cancer (BC) is a primary source of malignancy‐associated death, and the mortality rate is high due to its prevalence of metastasis. Corilagin (CLG), a bioactive constituent of numerous medicinal plants, exerts assorted pharmacological actions comprising anti‐cancer, apoptotic, anti‐inflammatory, and hepatoprotective. CLG possesses a substantial anti‐tumor prospective and less noxiousness i ...

... One approach to control dengue virus transmission is the symbiont Wolbachia, which limits viral infection in mosquitoes. Despite plans for its widespread use in Aedes aegypti, Wolbachia's mode of action remains poorly understood. Many studies suggest that the mechanism is likely multifaceted, involving aspects of immunity, cellular stress and nutritional competition. A previous study from our grou ...
... During wound regeneration, both cell adhesion and adhesion-inhibitory functions must be controlled in parallel. We developed a membrane with dual surfaces by merging the properties of carboxymethyl cellulose (CMC) and collagen using vitrification. A rigid membrane was formed by vitrification of a bi-layered CMC and collagen hydrogel without using cross-linking reagents, thus providing dual functio ...

Abstract:
... Building bio-based hydrogels with high strength and biocompatibility is still a challenge. Herein, we successfully constructed a hybrid double-network (DN) full biological hydrogel with excellent mechanical properties and biocompatibility by introducing a physically cross-linked gelatin (GEL) network in a covalently cross-linked poly (γ-glutamic acid) (γ-PGA) network. The γ-PGA-GEL DN hydrogel dem ...
... Bacillus toyonensis (a Gram-positive bacterium) and Pseudomonas aeruginosa (a Gram-negative bacterium) isolated from the different surfaces of a dairy plant in our previous study were selected as the test bacteria for the present study. These two test bacteria were investigated in terms of their attachment on the stainless steel test surfaces in a model dairy batch system. After incubation at 5 °C ...
... In the process of tumorigenesis and development, cancer cells must integrate and respond to complex and dynamic signals in the tumor microenvironment. Nevertheless, simulating the original biomechanical and biochemical microenvironment of different cells in vitro is a fundamental challenge in studying synergistic effects. To address this issue, we have proposed a biomimetic multi-factor stimulatio ...
... Conductive polymers, including polypyrrole (PPy), have garnered much attention as bioelectrodes because of their high conductivity, low interfacial resistance, environmental stability, and biocompatibility. In particular, the introduction of high-molecular weight hyaluronic acid (HA) into PPy enables the fabrication of biomimetic and biocompatible electrodes (i.e., PPy/HA) characterized by low bio ...
... Bone repair is a self-healing process. However, critical-sized bone defects need bone augmentation where bone tissue engineering plays vital role. Bone tissue Engineering (BTE) requires unique combinations of scaffolds, cells, and bio-signal molecules. Bone scaffold materials should be biocompatible, bioresorbable and exhibit biomimetic properties. Natural polymers, acquiring cell binding motives, ...
