Oral manifestations of inflammatory bowel disease
Inflammatory bowel diseases (IBD), including Crohn’s disease and ulcerative colitis, have important extraintestinal manifestations, notably in the oral cavity. These oral manifestations can constitute important clinical clues in the diagnosis and management of IBD, and include changes at the immune and bacterial levels. Aphthous ulcers, pyostomatitis vegetans, cobblestoning and gingivitis are important oral findings frequently observed in IBD patients. Their presentations vary considerably and might be well diagnosed and distinguished from other oral lesions. Infections, drug side effects, deficiencies in some nutrients and many other diseases involved with oral manifestations should also b…
A NOVEL APPROACH IN COLORECTAL CANCER AND DIABETES MANAGEMENT: ROLE OF METFORMIN AND RAPAMYCIN
Abstract The link between colorectal cancer (CRC), diabetes mellitus (DM) and inflammation is well established, and polytherapy, including rapamycin, has been commonly adopted. However, due to the relatively weak response of CRC to rapamycin, combination with other molecules including metformin has become a potentially promising approach. This study is a novel approach that aimed at assessing the effect of a combination therapy of metformin and rapamycin on the control or prevention of colorectal cancer in diabetic animals, in presence or absence of probiotics. Fifty NOD/SCIDs male mice developed xenograft by inoculating HCT116 cells into the flank; they were equally divided into diabetics …
Nerve growth factor and burn wound healing: Update of molecular interactions with skin cells
Burn wound healing is a very intricate and complex process that conventionally includes three interrelated and overlapping stages of hemostasis/inflammation, proliferation and remodeling. This review aims to explore the molecular interactions of NGF with the most prominent cell types in the skin and their respective secretory products during wound healing, particularly burn wound healing. Different types of cells such as, nerve cells, endothelial cells, mast cells, macrophages, neutrophils, keratinocytes and fibroblasts all come into play through a plethora of cytokines and growth factors including nerve growth factor (NGF). NGF is a pleiotropic molecule that exerts its effects on all the a…
