Nipple-sparing mastectomy (NSM) offers improved cosmesis for women undergoing mastectomy; however, there is increased risk for complications with this technique. We sought to determine if standard anatomic measurements could be used to predict complications of NSM. We performed a retrospective review of NSM for which anthropometric measurements of sternal notch to nipple distance, base width, and inframammary fold to nipple distance were available, and compared outcomes by anatomic measurements. We identified 102 cases of NSM with measurements available for study performed in 55 patients...

Breast cancer is the second leading cause of cancer‑related deaths in female patients, and the main reasons are late diagnosis, limited therapeutic options and metastasis. Therefore, development of molecular therapeutic targets for breast cancer to suppress tumorigenesis, growth and metastasis may improve the therapeutic options and be of great benefit to patients. Tumor necrosis factor-α-induced protein 8-like 2 (TIPE2) is a novel molecule for maintaining immune homeostasis and is involved in cancer development...

Sepsis is a severe inflammatory response to systemic infection that frequently affects the myocardium. Previous studies have suggested that resveratrol (RESV) is protective in sepsis. The present study aimed to investigate the role of sirtuin 1 (Sirt1) signaling in the protective effect of intraperitoneally administered RESV against sepsis‑induced myocardial injury. Cecal ligation and puncture, or a sham operation, were performed in male Sprague‑Dawley rats, and the levels of tumor necrosis factor (TNF)‑α and myeloperoxidase (MPO) were assessed by ELISA and an MPO activity kit, respectively...

Nuclear factor of activated T cells 5 (NFAT5) is a transcription factor that can be activated by extracellular tonicity. It has been reported that NFAT5 may increase the transcription of certain osmoprotective genes in the renal system, and the aim of the current study was to explore the role of NFAT5 in seawater inhalation‑induced acute lung injury. Though establishing the model of seawater inhalation‑induced acute lung injury, it was demonstrated that seawater inhalation enhanced the transcription and protein expression of NFAT5 (evaluated by reverse transcription‑polymerase chain reaction, immunohistochemistry stain and western blotting) and activation of nuclear factor (NF)‑κB (evaluated by western blotting and mRNA expression levels of three NF‑κB‑dependent genes) both in lung tissue and rat alveolar macrophage cells (NR8383 cells)...

Obesity is characterized by the abnormal or excessive fat accumulation that may impair health and extensive increase in body mass index (BMI). Childhood obesity may occur due to disturbances in metabolic regulation, which lead to metabolic syndrome and other diseases. Peripheral blood suspended immune cells are responsible for immune surveillance. The aim of the present study was to map the inflammatory cytokine expression pattern of isolated peripheral blood mononuclear cells (PBMCs) following lipopolysaccharide (LPS) stress in vitro and clinical chemistry parameters in the plasma of subjects...

Salidroside [2-(4-hydroxyphenyl)ethyl β-D-gluco-pyranoside (SAS)] has been identified as the most potent ingredient of the plant Rhodiola rosea L. Previous studies have demonstrated that it possesses a number of pharmacological properties, including anti-aging, anti-fatigue, antioxidant, anticancer and anti-inflammatory properties. In this study, to ascertain the molecular mechanisms responsible for the anti-inflammatory activity of SAS, we used phorbol-12-myristate-13-acetate (PMA) plus A23187 to induce inflammation in human mast cell line-1 (HMC-1)...

Aseptic loosening mediated by wear particle-induced osteolysis (PIO) remains the major cause of implant loosening in endoprosthetic surgery. The development of new vitamin E (α-tocopherol)-blended ultra-high molecular weight polyethylene (VE-UHMWPE) with increased oxidation resistance and improved mechanical properties has raised hopes. Furthermore, regenerative approaches may be opened, as vitamin E supplementation has shown neuroprotective characteristics mediated via calcitonin gene-related peptide (CGRP), which is known to affect bone remodeling in PIO...

Inflammatory bowel diseases (IBDs) are thought to develop as a result of complex interactions between host genetics, the immune system and the environment including the gut microbiome. Although an improved knowledge of the immunopathogenesis of IBDs has led to great advances in therapy such as the highly effective anti-tumor necrosis factor class of medications, a significant proportion of patients with Crohn's disease and ulcerative colitis do not respond to anti-tumor necrosis factor antibodies. Further understanding of the different immune pathways involved in the genesis of chronic intestinal inflammation is required to help find effective treatments for IBDs...

BACKGROUND: Necrosis of random pattern flaps caused by inadequate blood flow, especially in the distal part of the flap is one of the biggest challenges in reconstructive surgery. Various agents have been used to prevent flap ischemia. In this study, we used omeprazole, which is a potent inhibitor of gastric acidity to increase flap viability. METHODS: In this study, 35 Wistar-Albino type rats which were divided into 5 equal groups were used. Random-pattern dorsal skin flaps were raised in all groups at seventh day of the study...

It has been reported previously that the density of angiotensin II receptors is increased in the rat liver in experimentally-induced fibrosis. We hypothesized that pharmacological blockade of angiotensin receptors may produce beneficial effects in models of liver fibrosis. In this study, we used the widely used thioacetamide (TAA)-induced model of liver fibrosis (300 mg/L TAA ad libitum for 12 weeks). Rats received daily injections (i.p), lasting 4 weeks of the angiotensin II type 1 receptor antagonists, losartan 30 mg/kg (TAA + L) or telmisartan 10 mg/kg (TAA + T) and were compared to rat that received TAA alone...

Acute pancreatitis (AP) is a painful inflammatory disorder of the exocrine pancreas, ranking as the most common gastrointestinal reasons for hospitalization with no specific therapy currently. Diosgenyl saponins extracted from natural products and diosgenin or its derivatives have been shown to exert anti-inflammatory effects in various diseases. However, the therapeutic effects of diosgenyl saponins from Dioscorea zingiberensis C. H. Wright in AP have not yet been determined. Five compounds were extracted and screened for taurocholate-induced necrosis in mouse pancreatic acinar cells...

Compared to FDG, the signal of (18)F-labelled hypoxia-sensitive tracers in tumours is low. This means that in addition to the presence of hypoxic cells, transport properties contribute significantly to the uptake signal in static PET images. This sensitivity to transport must be minimized in order for static PET to provide a reliable standard for hypoxia quantification. A dynamic compartmental model based on a reaction-diffusion formalism was developed to interpret tracer pharmacokinetics and applied to static images of FAZA in twenty patients with pancreatic cancer...

Accumulating evidences suggested that tumor necrosis factor alpha inducible protein 3 (TNFAIP3) gene rs10499194, rs13207033 polymorphisms may be associated with the risk of rheumatoid arthritis (RA). However, these studies yielded contradictory findings. To clarify convincing associations, we conducted a comprehensive meta-analysis by searching in PubMed, Embase, and the China Knowledge Resource Integrated Database. Pooled odds ratios (ORs) and 95% confidence intervals (CIs) were calculated by using fixed-effect or random-effect models...

The introduction of neoadjuvant radiotherapy has allowed limb-preserving surgical treatment in patients with extremity soft tissue sarcoma, and the overall prognosis of this approach is similar to that of limb amputation. The benefits of this treatment, however, are often accompanied with a higher risk of major complications and blood vessel damage because of radiation-induced inflammation and necrosis of the vessel wall. In particular, it is associated with the rupture of large vessels like the femoral artery and more severe complications of wounds located in the proximal lower extremity...

BACKGROUND: The systemic immune system plays a role in inflammation and fibrogenesis associated with non-alcoholic steatohepatitis (NASH) and has become a potential target for drug development. In particular, the gut immune system has been suggested as a means for generating signals that can target the systemic immune system. AIM: To describe seven novel methods being developed for the treatment of NASH that target the gut immune system for alleviation of the systemic inflammatory response, including oral administration of fatty-liver-derived proteins, anti-CD3 antibodies, tumour necrosis factor fusion protein, anti-lipopolysaccharide antibodies, glucosylceramide, delayed-release mercaptopurine, and soy-derived extracts...

Metalloproteases, notably members of the matrix metalloprotease (MMP) and A Disintegrin And Metalloprotease (ADAM) families play crucial roles in tissue remodeling, the liberation of growth factors and cytokines from cell membranes (shedding) and cell-cell or cell-matrix interactions. Activity of MMPs or ADAMs must therefore be tightly controlled in time and space by activation of pro-enzymes upon appropriate stimuli and inhibition by endogenous tissue inhibitors of metalloproteases (TIMPs) or α2-macroglobulin to prevent irreversible tissue damage due to excessive degradation or uncontrolled release of potent inflammatory mediators, such as tumor necrosis factor-α (TNF-α)...
