Artificial skin has achieved considerable therapeutic results in clinical practice. However, artificial skin treatments for wounds in diabetic patients with impeded blood flow or with large wounds might be prolonged. Cell-based therapies have appeared as a new technique for the treatment of diabetic ulcers, and cell-sheet engineering has improved the efficacy of cell transplantation. A number of reports have suggested that adipose-derived stem cells (ASCs), a type of mesenchymal stromal cell (MSC), exhibit therapeutic potential due to their relative abundance in adipose tissue and their accessibility for collection when compared to MSCs from other tissues...

BACKGROUND: Necrotizing myositis is a rare but life-threatening soft-tissue infection characterized by rapidly spreading inflammation and subsequent necrosis of the affected tissue. The myositis is often caused by toxin-producing, virulent bacteria such as group A β-hemolytic streptococcus and associated with severe systemic toxicity. It is rapidly fatal unless diagnosed promptly and treated aggressively. However, necrotizing myositis is often initially misdiagnosed as a more benign soft-tissue infection as such fulminant, invasive muscle infections are rare with no more than 30 cases reported over the last century...

The mechanisms underlying endothelial cell injury and defective vascular repair in systemic sclerosis (SSc) remain unclear. Since the recently discovered angiogenic T cells (Tang) may have an important role in the repair of damaged endothelium, this study aimed to analyze the Tang population in relation to disease-related peripheral vascular features in SSc patients. Tang (CD3+CD31+CXCR4+) were quantified by flow cytometry in peripheral blood samples from 39 SSc patients and 18 healthy controls (HC). Circulating levels of the CXCR4 ligand stromal cell-derived factor (SDF)-1α and proangiogenic factors were assessed in paired serum samples by immunoassay...

OBJECTIVE: Patients with critical limb ischaemia (CLI) lack sufficient blood flow in to the limb, which leads to difficulties in the normal wound healing process. Therefore, maggot debridement therapy (MDT) has not generally been recommended for CLI patients. We evaluated the effectiveness of wound bed preparation by MDT in CLI patients who had undergone mid-foot amputation. METHODS: Patients who underwent mid-foot amputation after angioplasty between April 2014 and October 2016 were retrospectively investigated by classifying them into an MDT group or a conventional treatment group...

Previous studies in our laboratory showed that Daucus carota oil extract (DCOE) possesses in vitro and in vivo anticancer activities. Chemical analysis of DCOE led to the isolation of β-2-himachalen-6-ol (HC) which exhibited potent anticancer activity against colon, breast, brain and skin cancer cells. The present study investigates the anticancer activity of HC against SW1116 colon cancer cell lines, and evaluates its effect in a 1,2-dimethylhydrazine (DMH) colon carcinogenesis black6 mice model. The SW1116 colon cancer cell line was treated with HC (1, 5, 10 and 25 μg/ml) and cell viability was evaluated with WST 1 assay kit...

PURPOSE: Findings concerning the effects of exhaustive exercise on cognitive function are somewhat equivocal. The purpose of this study was to identify physiological factors that determine executive function after exhaustive exercise. METHODS: Thirty-two participants completed the cognitive tasks before and after an incremental exercise until exhaustion (exercise group: N = 18) or resting period (control group N = 14). The cognitive task was a combination of a Spatial Delayed-Response (Spatial DR) task and a Go/No-Go task, which requires executive function...

BACKGROUND: Dynamic optical coherence tomography (D-OCT) has recently been introduced in dermatology. In contrast to 'Standard' OCT imaging, which exclusively relies on the morphological analysis of the tissue, D-OCT allows the in-vivo visualisation of blood flow. Preliminary D-OCT data showed differences in the vascularisation of nevus to melanoma transition, suggesting that this technology may help to differentiate between benign and malignant lesions. OBJECTIVE: Several factors may influence the quality of D-OCT imaging...

Microsurgical procedure of free tissue transfer in critical limb ischemia patients with large ulceration has already been established. The nutrient flap concept was that transferred tissue functioned not only to cover the skin defect but also as a supplementary blood supply to the ischemic lower leg. This report showed the justification for this concept, which was rarely discussed. A 58-year-old male patient with progressive forefoot gangrene caused by arteriosclerosis obliterans was presented. The distal bypass procedure was performed as revascularization surgery, and a latissimus dorsi (LD) myocutaneous flap was transplanted to cover ulceration...

Clinical manifestation of high grade fever and skin rash prior to neutrophil engraftment, which is called pre-engraftment syndrome (PES) or pre-engraftment immune reaction, has been frequently observed after cord blood transplantation (CBT). The pathophysiology of PES is poorly understood, but cytokine storm during the early phase of CBT is thought to be one of the main cause of PES. However, the cytokine profiles of PES after CBT are unclear. Therefore, we examined the relationship between serum cytokine profiles and PES in 44 adult patients who received CBT in our institute between February 2013 and June 2016...

The nucleoside adenosine is a potent regulator of vascular homeostasis, but it remains unclear how expression or function of the adenosine-metabolizing enzyme adenosine kinase (ADK) and the intracellular adenosine levels influence angiogenesis. We show here that hypoxia lowered the expression of ADK and increased the levels of intracellular adenosine in human endothelial cells. Knockdown (KD) of ADK elevated intracellular adenosine, promoted proliferation, migration, and angiogenic sprouting in human endothelial cells...
