: Diabetic non-healing wounds are a major clinical problem. The mechanisms leading to poor wound healing in diabetes are multifactorial but unresolved inflammation may be a major contributing factor. The complement system (CS) is the most potent inflammatory cascade in humans and contributes to poor wound healing in animal models. Signal transducer and activator of transcription 4 (STAT4) is a transcription factor expressed in immune and adipose cells and contributes to upregulation of some inflammatory chemokines and cytokines...

Chibby1 (Cby1) was originally isolated as a binding partner for β-catenin, a dual function protein in cell-cell adhesion and in canonical Wnt signaling. The canonical Wnt/β-catenin pathway is dysregulated in various diseases including cancer, most notably of the gastrointestinal origin. To investigate the role of Cby1 in colorectal tumorigenesis, we generated stable Cby1-knockdown (KD) SW480 colon cancer cells. Unexpectedly, we found that Cby1 KD induces mesenchymal-to-epithelial transition (MET)-like changes in SW480 as well as in HEK293 cells...

The highly reactive dicarbonyl methylglyoxal (MGO) is mainly formed as byproduct of glycolysis. Therefore, high blood glucose levels determine increased MGO accumulation. Nonetheless, MGO levels are also increased as consequence of the ineffective action of its main detoxification pathway, the glyoxalase system, of which glyoxalase 1 (Glo1) is the rate-limiting enzyme. Indeed, a physiological decrease of Glo1 transcription and activity occurs not only in chronic hyperglycaemia but also with ageing, during which MGO accumulation occurs...

OBJECTIVE Large myelomeningocele defects and poor surrounding tissue quality make some defects particularly difficult to close primarily. This paper describes the superior gluteal artery perforator (SGAP) flap technique for defect closure and long-term clinical outcomes. METHODS The technique for closing a myelomeningocele with an SGAP flap is described. A retrospective chart review was performed on a cohort of 11 patients who underwent closure in this manner. RESULTS Between 1999 and 2015, 271 myelomeningoceles were closed, 11 of which were SGAP flap closures...

OBJECTIVE: A previous study suggested that the frequency with which patients visit wound care clinics influences the rate of chronic wound healing but high bias was present with regard to wound care centre selection. The objective of this retrospective cohort study was to confirm this finding by using a very large sample size of diabetic foot ulcers (DFUs) from the US Wound Registry. METHOD: Patients who visited the clinic more than once for a new DFU were eligible for study inclusion...

Chronic wounds, pressure sores, lesions and infections of microbial origin in bedridden, paralyzed or malnutrition patients remain the object of study of many researchers. There are several intrinsic and extrinsic factors involved in the development of these disorders, which are related to the patient's immune system, making it unable to respond effectively to the treatment of the wound. These factors can be properly controlled, giving particular importance to the ethiology and stage of the wound, as well as the time periods corresponding to the replacement of the dressings...

A 71year old female Caucasian farmer without any known immunosuppression presented with a painful ulcer of her right lower leg after a trauma caused by a wood billet. There was no response to empirical antibacterial treatment. An ulcer biopsy showed an invasive Candida infection of the soft tissue and leucocytoclastic vasculitis. Voriconazole treatment was followed by wound healing. Invasive Candida infection and localized Candida vasculitis represent a rare cause of persisting leg ulcers. The similar clinical picture of chronic venous leg ulcers might blur the true cause and refractory cases should therefore promptly be processed by histopathological diagnostics...

BACKGROUND: The primary purpose of this retrospective study was to report on a consecutive series of 102 patients with diabetes mellitus (DM) who underwent transtibial amputation (TTA) for chronic infections and nonreconstructable lower extremity deformities. A secondary aim was to compare the outcomes of TTA patients with end-stage renal disease on dialysis (ESRD) to patients without ESRD, and to identify risk factors for mortality after TTA. METHODS: This cohort involved a consecutive series of patients who were treated by a single surgeon...

Burns are the most extensive forms of soft tissue injuries occasionally resulting in extensive and deep wounds and death. Burns can lead to severe mental and emotional distress, because of excessive scarring and skin contractures. Treatment of burns has always been a difficult medical problem and many different methods have been used to treat such injuries, locally. Biofilms are a collection of microorganisms that delay wound healing. One of the new methods of prevention and treatment of burn wound infections is application of antimicrobials, which act on biofilms and prevent the wound infection...

The presence of biofilms in chronic non-healing wounds, has been identified through in vitro model and in vivo animal data. However, human chronic wound studies are under-represented and generally report low sample sizes. For this reason we sought to ascertain the prevalence of biofilms in human chronic wounds by undertaking a systematic review and meta-analysis. Our initial search identified 554 studies from the literature databases (Cochrane Library, Embase, Medline). After removal of duplicates, and those not meeting the requirements of inclusion, nine studies involving 185 chronic wounds met the inclusion criteria...

Scarless wound healing and functional regeneration are typical processes of the fetus, gradually lost during post-natal life, and maximally attributed to fetal skin tissue and induced by fetal skin fibroblasts. The latter have been successfully applied to post-natal wounds, with clear advantages compared with autologous dermis grafts or adult fibroblast applications. Our goal was to functionally identify and uncover key factors and mechanisms through the analysis of secretomes, the principal players in all cell therapies based on mesenchymal stromal cells (MSCs)...

Psoriasis is a chronic relapsing immune mediated disorder of the skin. The disease presents itself with well featured clinical and histological characteristics however the aetiology of the disease still remains obscure. The current systemic therapies aim to eliminate the symptoms of disease rather than offering a complete cure. Parangichakkai chooranam (PC), a Siddha oral herbal formulation has been widely prescribed for the treatment of psoriasis. Though the medication is highly prescribed by the Siddha healers the mechanism of PC for the treatment of psoriasis remains to be elucidated...

Chronic dermal wounds are a devastating problem that disproportionally affect individuals with conditions such as diabetes, paralysis, or simply old age. These wounds are extremely challenging to treat due to a heterogeneous combination of causative factors, creating a substantial burden on healthcare systems worldwide. Despite their large impact, there is currently a startling lack of options for effectively treating the underlying biological changes that occur within the wounds. Biomaterials possess an enticing ability to provide new comprehensive approaches to healing these devastating wounds; advanced wound dressings are now being developed that enable the ability to coordinate temporal delivery of multiple therapeutics, protect sensitive biologics from degradation, and provide supportive matrices that encourage the growth of tissue...

Chronic wounds affect over 4 million individuals and pose a significant burden to the US healthcare system. Diabetes, venous stasis, radiation or paralysis are common risk factors for chronic wounds. Unfortunately, the current standard of care (SOC) has a high relapse rate and these wounds continue to adversely affect patients' quality of life. Fortunately, advances in tissue engineering have allowed for the development of cell-based wound dressings that promote wound healing by improving cell migration and differentiation...

The prevention of cancer development and its progression is an urgent unmet medical need. Novel knowledge on the biology of cancer has evidenced that genetic changes occurring within cancer cells contribute, but are not sufficient, for tumor promotion and progression. The results of clinical studies and experimental animal models have suggested pursuing new avenues for the prevention of cancer development in the early stages, by using drugs that modulate platelet responses and those interfering with the synthesis and action of the mediators of inflammation...

Objective: The extracellular matrix consists of critical components that affect fibroblast polarization and migration. The existence of both intrinsic and extrinsic electrical signals that play essential roles in the development, physiology, regeneration, and pathology of cells was discovered over a century ago. In this study, we study how the Bioelectric Field Enhancement (BEFE) device and its generated electromagnetic field (EMF) by continuous direct current (DC) significantly affect the membrane potential and cell migration of fibroblasts in vitro...

Objective: In diabetes, hyperglycemia causes the accumulation of advanced glycation end products (AGEs) that trigger reactive oxygen species (ROS) generation through binding the receptor for AGEs (RAGE). Because exogenous growth factors have had little success in enhancing chronic wound healing, we investigated whether hyperglycemia-induced AGEs interfere with cellular responses to extracellular signals. We used stromal cell-derived factor-1 (SDF-1), an angiogenic chemokine also known to promote stem cell recruitment in skin wounds...

The degree of crosslinking within acellular dermal matrices (ADM) seems to correlate to neovascularization when used in ventral hernia repair (VHR). Platelet-rich plasma (PRP) enhances wound healing through several mechanisms including neovascularization, but research regarding its effect on soft tissue healing in VHR is lacking. We sought to study the effect of crosslinking on PRP-induced neovascularization in a rodent model of bridging VHR. We hypothesized that ADM crosslinking would negatively affect PRP-induced neovessel formation...

Smart multifunctional materials can play a constructive role in addressing some very important aging-related issues. Aging affects the ability of older adults to continue to live safely and economically in their own residences for as long as possible. Thus, there will be a greater need for preventive, acute, rehabilitative, and long-term health care services for older adults as well as a need for tools to enable them to function independently during daily activities. The objective of this paper is, thus, to present a comprehensive review of some potential smart materials and their areas of applications to gerontology...

Angiogenesis is a regulated process integral to many physiological and pathological situations, including carcinogenesis and tumor growth. The majority of the angiogenic processes are related to inflammation. The interplay is not only important in the case of pathogen entry but also influential in chronic inflammatory diseases, tumor growth and tissue regeneration. Modulating the interaction between inflammation and angiogenesis could be an important target for cancer treatment and wound healing alike. Ginseng has a wide range of pharmacological effects, including anti-inflammatory and angiogenesis-modulating activities...
