Skin tightening is one of the cornerstones of skin rejuvenation and is defined as the improvement of skin laxity and crepiness of the skin. There are several energy-based devices that can produce significant skin tightening without surgery, both on and off the face. The mechanisms of skin tightening involve collagen denaturation resulting in collagen shrinkage and tissue tightening, and the wound healing response that generates new collagen and elastin. These hypothesized mechanisms of skin contraction leading to clinical skin tightening have been derived from histological, immunohistochemical, and electron microscope analysis, as well as in vitro and in vivo experiments...

BACKGROUND/AIMS: Doublecortin-like kinase 1 (DCLK1) is emerging as a tumor-specific stem cell marker in pancreatic cancer (PC). MicroRNA-195 (miR-195) plays an important role in many types of tumors. However, the roles of DCLK1 in cancer and miRNAs that directly regulate DCLK1 have not been elucidated. The goal of this study is to assess the effects of miR-195 on inhibiting DCLK1 and to clarify the regulating mechanism of miR-195-DCLK1 in PC cells. METHODS: The expression of DCLK1 protein and miR-195 in PC tissues and adjacent healthy pancreatic tissues was detected by Western blot and quantitative reverse transcription polymerase chain reaction (qRT-PCR), respectively and the correlation between overall survival of PC patients and expression of DCLK1 was measured by Kaplan-Meier analysis...

Liver fibrosis is overly exuberant wound healing that leads to portal hypertension or liver cirrhosis. Recent studies have demonstrated the functions of bone morphogenetic protein 9 (BMP9) in liver fibrosis, and thus, targeting liver-specific BMP9 abnormalities will become an attractive approach for developing therapeutics to treat liver fibrosis. Here, we reveal that BMP9 serves as a valuable serum diagnostic indicator and efficient therapeutic target to attenuate liver fibrogenesis. Our analysis of biopsies from liver fibrotic patients revealed that higher BMP9 levels accompanied advanced stages of liver fibrosis...

Diabetes is characterized by poor wound healing which currently lacks an efficacious treatment. The innate repair receptor (IRR) is a master regulator of tissue protection and repair which is expressed as a response injury or metabolic stress, including in diabetes. Activation of the IRR might provide benefit for diabetic wound healing. A specific IRR agonist cibinetide was administered in an incisional wound healing model performed mice with genetic diabetes (db+/db+) and compared to the normal wild-type. Animals were treated daily with cibinetide (30μg/kg/s...

BACKGROUND: Chest drains are used routinely in thoracic surgery. Often a pursestring or mattress suture is used to facilitate closure of the defect on removal of the drain. This stitch can cause an unsightly scar, increase drain removal pain, and necessitate that the patient attend a community health care center to have this removed. The objective of this study was to assess whether this stitch is necessary in modern thoracic surgical practice. METHODS: Data from a single surgeon's practice were collected over an 18-month period...

Myofibroblasts participate in physiological wound healing and pathological fibrosis.  Myofibroblast differentiation is characterized by the expression of alpha-smooth muscle actin (α-SMA) and extracellular matrix (ECM) proteins, and is dependent on metabolic reprogramming.  In this study, we explored the role of glutaminolysis and metabolites of the tricarboxylic acid cycle (TCA) in supporting myofibroblast differentiation.  Glutaminolysis converts glutamine (Gln) into alpha-ketoglutarate (α-KG), a critical intermediate in the TCA cycle...

Chronic kidney disease (CKD) is a global socioeconomic problem. It is characterised by the presence of differentiated myofibroblasts that, in response to TGF B-1, produce tissue fibrosis, leading to renal failure. Here we define a novel interaction between the SET9 lysine methyltransferase and SMAD3, the principle mediator of TGF B-1 signalling in myofibroblasts. We show that SET9 deficient fibroblasts exhibit globally altered gene expression profiles in response to TGF B-1, whilst overexpression of SET9 enhances SMAD3 transcriptional activity...

Cardiac fibroblasts (CF) act as sentinel cells responding to chemokines, cytokines and growth factors released in cardiac tissue in cardiac injury events, such as myocardial infarction (MI). Cardiac injury involves the release of various damage-associated molecular patterns (DAMPs) including heparan sulfate (HS), a constituent of the extracellular matrix (ECM), through the TLR4 receptor activation triggering a strong inflammatory response, inducing leukocytes recruitment. This latter cells are responsible of clearing cell debris and releasing cytokines that promote CF differentiation to myofibroblast (CMF), thus initiating scar formation...

The frequent use of antibiotics against microbial infections may lead the emergence of antibiotic resistant microbial strains. To overcome these microbial strains, we need to fabricate alternative materials which can handle them. It is for this reason, we have fabricated cellulose (CE) based filter paper (FP) composite scaffolds comprising of adsorbed chitosan (CS) and sliver (Ag) nanoparticles (NPs). The AgNPs are incorporated in the CS layer of the composite scaffold. Prior to evaluate the efficacy of the scaffolds against gram positive and gram negative bacterial strains, the scaffolds were characterized for the presence of the Ag NPs with field emission scanning electron microscope (FE-SEM), fourier transform infrared (FTIR) spectroscopy and x-ray diffractometer (XRD)...

As regenerative medicine matures as a field, more promising technologies are being translated from the benchtop to the clinic. However, many of these strategies are designed with otherwise healthy hosts in mind and validated in animal models without other co-morbidities. In reality, many of the patient populations benefiting from drug delivery and tissue engineering-based devices to enhance wound healing also have significant underlying immunodeficiency. Specifically, patients suffering from diabetes, malignancy, human immunodeficiency virus, post organ transplantation, and other compromised states have significant pleotropic immune defects that affect wound healing...
