Introduction: Capnocytophaga are facultative anaerobic Gram-negative bacilli and recognized as opportunistic pathogens of various extraoral infections. Only a few studies attempted to identify all the seven species of Capnocytophaga phenotypically and genotypically in healthy individuals and patients with chronic periodontitis. Studies to determine the prevalence of Capnocytophaga in subgingival plaque samples from healthy individuals, chronic gingivitis and periodontitis among Indian population are lacking...

Introduction: The micro-flora of oral cavity is a myriad of micro-organism. Any infection of oral cavity leads to diseased condition which is a transitional transformation of the micro-organism in a specific paradigm depending upon the diseased condition. Periodontitis is one of the predominant chronic diseases which is a multifactorial infection. Porphyromonas gingivalis is a key etiological agent in causing periodontitis. To study the predominance of these bacteria in the diseased condition is important to detect, quantify and to find its efficacy by comparing different methods for identification...

Melanin concentrating hormone (MCH) is a highly conserved cyclic peptide present in vertebrates. In this study, we describe the organization of MCH-immunoreactive (MCH-ir) cells and fibres in different regions of the brain in the cichlid fish Oreochromis mossambicus. Only MCH-ir fibres were observed in dorsal and ventral subdivisions of the telencephalon, the preoptic area and magnocellular and parvocellular divisions of the nucleus preopticus, and in hypothalamic areas such as the suprachiasmatic nucleus and tuberal area...

Background: The prognosis of glioblastoma (GBM) remains dismal because therapeutic approaches have limited effectiveness. A new targeted treatment using MEK inhibitors, including trametinib, has been proposed to improve GBM therapy. Trametinib had a promising preclinical effect against several cancers, but its adaptive treatment resistance precluded its clinical translation in GBM. Previously, we have demonstrated that protein arginine methyltransferase 5 (PRMT5) is upregulated in GBM and its inhibition promotes apoptosis and senescence in differentiated and stem-like tumor cells, respectively...

Surface coatings, including paints, stains, and sealants, have recently become a focus of "nano-enabled" consumer product engineering. Specifically, zinc oxide (ZnO) nanoparticles (NPs) have been introduced to surface coatings to increase UV resistance. As more "nano-enabled" products are made available for purchase, questions arise regarding their long-term environmental and human health effects. This study tracked the transformation of NP additives commonly added to consumer paints and stains using ZnO NPs as a model system...

BACKGROUND: It has been shown that subacromial bursa (SAB) harbors connective tissue progenitor cells (CTPCs). The purpose of this study was to evaluate the effects of implantation of subacromial bursa-derived cells (SBCs) suspended in a fibrin sealant bead and implantation of SAB tissue at rotator cuff repair site on biomechanical properties of the repair in a mouse (C57Bl/6) model of supraspinatus tendon (ST) detachment and repair. METHODS: Part One: Murine SAB tissue was harvested and cultured...

Approximately half of annual musculoskeletal injuries in the US involve tendon tears. The naturally hypocellular and hypovascular tendon environment makes tendons injury-prone and heal slowly. Tendon tissue engineering strategies often use biomimetic scaffolds combined with bioactive factors and/or cells to enhance healing. FDA-approved growth factors to promote tendon healing are lacking, which highlights the need for safe and effective bioactive factors. Our previous work evaluated insulin as a bioactive factor and identified an optimal dose to promote in vitro mesenchymal stem cell survival, division, and tenogenesis...

3D bioprinting has enabled the creation of biomimetic tissue constructs for regenerative medicine and in vitro model systems. Large-scale production of 3D structures at the micron-scale resolution is achieved through bioprinting using custom bioinks. Stability and 3D construct compliance play an important role in offering cells with biomechanical cues that regulate their behavior and enable in vivo implantation. Various crosslinking strategies are developed to stabilize the 3D printed structures and new methodologies are constantly being evaluated to overcome the limitations of the existing methods...

Silica biomaterials including Bioglass offer great biocompatibility and bioactivity but fail to provide pore and degradation features needed for tissue engineering. Herein we report on the synthesis and characterization of novel amorphous silica fiber matrices to overcome these limitations. Amorphous silica fibers were fused by sintering to produce porous matrices. The effects of sacrificial polymer additives such as polyvinyl alcohol (PVA) and cellulose fibers (CF) on the sintering process were also studied...

Although bone tissue allografts and autografts aremoften used as a regenerative tissue during the bone healing, their availability, donor site morbidity, and immune response to grafted tissue are limiting factors their more common usage. Tissue engineered implants, such as acellular or cellular polymeric structures, can be an alternative solution. A variety of scaffold fabrication techniques including electrospinning, particulate leaching, particle sintering, and more recently 3D printing have been used to create scaffolds with interconnected pores and mechanical properties for tissue regeneration...
