No proper data on prognosis and management of type-2 diabetic ST elevation myocardial infarction (STEMI) patients with culprit obstructive lesion and multivessel non obstructive coronary stenosis (Mv-NOCS) exist. We evaluated the 12-months prognosis of Mv-NOCS-diabetics with first STEMI vs.to non-diabetics, and then Mv-NOCS-diabetics previously treated with incretin based therapy vs.

Type 1 diabetes (T1D) is an irreversible degenerative disease with severe complications such as heart disease, nephropathy, neuropathy, and retinopathy. Although exogenous insulin administration is a life-saving therapy, it does not cure the disease. This review addresses the epigenetic mechanisms responsible for the development of T1D and discusses epigenetic-based strategies for prevention and treatment of the disease.

Autologous fat grafting procedures in plastic surgery have been extensively used to reinforce soft tissue in congenital or acquired tissue impairments. With this background, the aim of this study is firstly to examine the impact of a selective centrifugation on existing adipose stem cells (ASCs) in terms of stemness profile maintenance and, secondly, to investigate the effect of restoring volume in reconstruction on patients affected by soft tissue damage. After centrifugation, the fat graft products were separated into two layers and subsequently examined in vitro for the expression of CD34, CD90, CD117, CD105, CD29, CD31, CD44, CD73, CD133, CD14 and CD45 markers by flow cytometry and gene expression analyses were performed for Sox2, WNT3A, END, CD44, FUT4, COLL1, CTNNB1, hbEGF, KRTLG, MMP2 and VIM genes.

Lipomas are benign solid tumours that develop in soft tissues with origin in mesenchymal progenitors. Macroscopically, they appear as soft-elastic nodules, varying in volume from a few millimiters to several centimetres and can enlarge progressively. Although they are usually asymptomatic, they can cause symptoms due to nerve or vessel compression.

Breast augmentation combined with mastopexy is associated with a significantly higher complication rate than augmentation alone. The combination of mastopexy and breast implants has revealed a moderate recurrence of breast ptosis in many patients particularly with use of medium to large implants. Ptosis is the "bottoming out" of the breast tissue with loss of the desired roundness, due to the ptosis of the breast implant and the mammary tissue.

Lipomas are the most common benign tumors of the adipose tissue and can be located in any region of the body. In most cases lipomas are small and asymptomatic, but they can at times reach considerable dimensions and, depending on their anatomic site, hinder movements, get inflamed, cause lymphedema, pain and/or a compression syndrome.
We here report the case of an otherwise healthy patient who came to our observation with a giant bulk in the left lumbar region which had been showing progressive growth in the previous 5-6 years.

Brachial ptosis is one of the consequences of massive weight loss. At an early stage, brachial ptosis can be corrected by liposuction, dermolipectomy and liposuction, or minibrachioplasty while the most advanced stage requires extended brachioplasty. Since brachioplasty was first described, various techniques have been proposed in the management of upper extremity contour deformities.

Gynecomastia is the benign proliferation of the glandular tissue in the male breast. This condition is thought to be caused by the imbalance between estrogen action relative to androgen action at the breast tissue level. Bilateral gynecomastia is frequently found in the neonatal period, early in puberty, and with increasing age.

Cancer stem cells (CSCs) have been defined as 'a cell within a tumor that possesses the capacity to self-renew and to cause the heterogeneous lineages of cancer cells that comprise the tumor'. The CSC hypothesis postulates that a small subpopulation of cancer cells drives tumor initiation, growth and metastasis. CSCs have been isolated from breast cancer using CD44+/CD24-/low phenotype.

Prepubertal gynecomastia is characterized by the presence of palpable uni- or bilateral breast tissue in boys without other signs of sexual maturation. It may be the endocrine expression of rare syndromes such as Peutz-Jeghers syndrome (PJS). This study aimed to evaluate the effectiveness of anastrozole and to describe an innovative surgical approach.

To date, silicone gel and silicone occlusive plates are the most useful and effective treatment options for hypertrophic scars (surgical and traumatic). Use of silicone sheeting has also been demonstrated to be effective in the treatment of minor keloids in association with corticosteroid intralesional infiltration. In our practice, we encountered four problems: maceration, rashes, pruritus and infection.

Stem cell based therapies for the repair and regeneration of various tissues are of great interest for a high number of diseases. Adult stem cells, instead, are more available, abundant and harvested with minimally invasive procedures. In particular, mesenchymal stem cells (MSCs) are multi-potent progenitors, able to differentiate into bone, cartilage, and adipose tissues.

Keloids and hypertrophic scars are abnormal responses to wound healing. In general, keloids exhibit a proliferative growth beyond the margins of the scar and remain persistent; while hypertrophic scars are contained to the original wound and may regress over time. In particular, keloid formation is one of the most challenging clinical problems, with increasing frequency in surgical practice.

The use of adipose tissue transfer in plastic and reconstructive surgery is not new and has been studied extensively. Due to different results with regard to adipose cell damage and the level of survival of the transferred tissue in clinical practice, the authors aimed to investigate the effects of centrifugation on fat aspirates to optimize the centrifugal force for fat transplantation and to obtain an increased number of intact adipose progenitor cells. The following different centrifugation forces were evaluated in vitro in terms of fat decantation: 3,000 rpm (1,500×g), 1,300 rpm (250×g), and 500 rpm (50×g).

The role of surgically removing subcutaneous fat by abdominoplasty on circulating inflammatory markers and myocardial dysfunction, evaluated by myocardial performance index (MPI), were investigated. Twenty volunteers submitted to the abdominoplasty (abdominoplasty group), and other 28 women treated by hypocaloric diet (diet group) were evaluated. Echocardiographic parameters of MPI, circulating levels of tumor necrosis factor (TNF)-alpha and interleukin (IL)-6, were performed at baseline and 2 months later.

Because the ubiquitin-proteasome pathway (UPS) is required for activation of nuclear factor kappa beta (NFkB), a transcription factor that regulates inflammatory genes, we evaluated the UPS activity, NFkB activation, and tumor necrosis factor-alpha (TNF-alpha), a proinflammatory cytokine, in ischemic specimens of diabetic myocardium and relate them to the glycemic control (HbA(1c)), oxidative stress (nitrotyrosine, a modified amino acid produced by reactive O(2)), and cardiac outcome (echocardiographic parameters). Moreover, the role of UPS, NFkB, and TNF-alpha in the cardiac tissue injury of acute ischemia/reperfusion (I/R) was evaluated in streptozotocin (STZ)-hyperglycemic rats. Finally, this study aimed to elucidate whether an intervention on UPS with bortezomib, an inhibitor of UPS, may counteract the extensive myocardial infarction and increased inflammatory reaction into the hyperglycemic myocardium.

This study aimed to observe the effects of ultrasound waves at different frequencies on abdominal fat tissue. External ultrasound-assisted lipectomy (XUAL) via both histologic and immunohistochemic examinations was used to assess adipose tissue alterations, including cells and collagenic fibers. The results, at the immunofluorescence level, show that ultrasound used at 1 MHz with a potency of 3 W resulted in no alterations or only limited cell destruction with collagen fibers intact.

Adipose tissue is a metabolically active tissue. The hypertrophic fat cells of obese patients produce increased quantities of leptin and tumor necrosis factor-alpha (TNF-alpha) and are less sensitive to insulin. This study aimed to determine whether aspirating large amounts of these subcutaneous fat cells by large-volume liposuction (LVL), could change the metabolic profile in 123 obese women.

All-trans-retinoic acid (RA) regulates cellular growth, differentiation and apoptosis in human prostate by binding to RA receptors. Non-genomic retinoid effects on signal transduction kinases in the cytoplasm are also described in several cells but they are still unknown in prostate cells.
Using an epithelial cell line derived from normal human prostate (EPN), and normal (NPEC) and malignant (CPEC) epithelial primary cultures of human prostate, we have examined effects of RA on both extracellular signal-regulated kinase 1/2 (Erk1/2) and cAMP accumulation.

Obesity is associated with an increased risk of developing atherosclerosis, which may be mediated, at least in part, by increased secretion of proinflammatory cytokines by adipose tissue. We examined the hypothesis that circulating levels of IL-18 were elevated in obese women and would be reduced by weight loss. In a sample of 40 obese (body mass index, 36.
