The incidence of bone disorders, from trauma, tissue degeneration due to ageing, pathological conditions to cancer, has been increasing. The pursuit for bone graft substitutes to assist in regenerating large bone defects is ever growing as a result of the shortage in conventional autografts and allografts, in addition to the associated risks of disease transmission. However, the use of alloplastic biomaterials is limited in clinical settings, as further investigations are required to address the properties of synthetic grafts to mimic the native bone tissue and deliver desirable biomolecules to facilitate bone regeneration...

eHealth and mobile health (mHealth) offer patients, healthcare providers, researchers, and policy makers new potential to improve wellness, practice prevention and reduce suffering from diseases. While the eHealth market is growing to an expected US $26 billion, its potential in the field of Urology is still underused. Research has shown that currently only 176 apps (of the 300,000 medical apps available) were found in the Apple App Store and Google Play Store, of which 20 were prostate cancer related. Three good examples of eHealth/mHealth applications are the Rotterdam Prostate Cancer Risk Calculator (RPCRC) website and app, the Prostate cancer Research International Active Surveillance (PRIAS) website and the Follow MyPSA app for men on active surveillance for prostate cancer: they are tools with a clear vision that offer true added value in daily clinical practice and which positively influence healthcare beyond borders...

Although it only accounts for approximately 5% of all female cancer cases, ovarian cancer (OC) ranks as the fifth leading cause of death due to cancer in women. We have evaluated the potential of an orally administered microparticulate vaccine incorporating an immunodominant epitope peptide derived from the cancer/testis antigen sperm protein 17 (SP17) aberrantly expressed in OC, to retard the progression of the disease. The peptide antigen and the immune-stimulatory toll-like receptor 9 ligand CpG oligonucleotide were incorporated into spray dried microparticles composed of enteric and sustained release polymers together with the Aleuria aurantia lectin targeting microfold cells present in the gut-associated lymphoid tissue...

PURPOSE: In spite of good initial therapy response neuroblastomas often spread to distant organs or relapse after periods of remission. Dysregulation of apoptosis, a hallmark of cancer, is often effected by elevated levels of antiapoptotic signals leading to resistance against chemotherapeutic drugs. Inhibitors of apoptosis proteins (IAPs) are crucial cellular apoptosis regulators. Targeting IAPs with Smac mimetics has been demonstrated as a promising strategy for treatment of neuroblastoma and other tumors...

To delineate the role of human papillomavirus (HPV) in laryngeal cancer in Southern Chinese, a retrospective cross-sectional study was conducted in a major otorhinolaryngology referral center in Hong Kong. Eighty-five Chinese patients with histology-confirmed laryngeal squamous cell carcinoma (LSCC) diagnosed between 2005 and 2010 were examined for the status of HPV by PCR, and the expression of p16 and p53 by immunohistochemistry. The HPV, p16 and p53 findings were correlated with clinicopathological features, recurrence and 5-year survival...

The extent of metal release from implant materials that are irradiated during radiotherapy may be influenced by irradiation-formed radicals. The influence of gamma irradiation, with a total dose of relevance for radiotherapy (e.g., for cancer treatments) on the extent of metal release from biomedical stainless steel AISI 316L and a cobalt-chromium alloy (CoCrMo) was investigated in physiological relevant solutions (phosphate buffered saline with and without 10 g/L bovine serum albumin) at pH 7.3. Directly after irradiation, the released amounts of metals were significantly higher for irradiated CoCrMo as compared to nonirradiated CoCrMo, resulting in an increased surface passivation (enhanced passive conditions) that hindered further release...

Human triple-negative breast cancer (TNBC) is the most aggressive and poorly understood subclass of breast cancer. Glucose transporters (GLUTs) are required for glucose uptake in malignant cancer cells and are ideal targets for cancer therapy. To determine whether the inhibition of GLUTs could be used in TNBC cell therapy, the apple polyphenol phloretin (Ph) was used as a specific antagonist of GLUT2 protein function in human TNBC cells. Interestingly, we found that Ph (10-150 μM, for 24 h) inhibited cell growth and arrested the cell cycle in MDA-MB-231 cells in a p53 mutant-dependent manner, which was confirmed by pre-treatment of the cells with a p53-specific dominant-negative expression vector...

BACKGROUND: Participation in regular physical activity holds key benefits for cancer survivors, yet few cancer survivors meet physical activity recommendations. This study aimed to develop and pilot test a mHealth app referral service aimed at assisting cancer survivors to increase their physical activity. In particular, the study sought to examine feasibility and acceptability of the service and determine preliminary efficacy for physical activity behaviour change. METHODS: A systematic search identified potentially appropriate Apple (iOS) and Android mHealth apps...

Background: Stereotactic body radiation therapy (SBRT) is an advanced technique of external beam radiation therapy that delivers large ablative doses of radiation. In the past decade, many cancer centers have adopted SBRT as one mode of radically treating small-sized hepatocellular carcinoma (HCC), based on encouraging clinical outcomes. SBRT thus seems reasonable as first-line treatment of inoperable HCC confined to the liver. However, most of the clinical studies to date have been retrospective in nature, with key issues still under investigation...

Bioactive polyphenolic compounds derived from plants are being utilized for prevention of various chronic diseases including cancer and cardiovascular disorders. Quercetin, a potential poly-phenolic flavonol, found in onions, apples and berries, has been implicated against cancer proliferation, chronic inflammation and various other oxidative manifestations. Evidences suggested that quercetin negatively regulates the numerous crucial signaling pathways associated with life-threatening diseases. Major signaling pathways including NF-κB, MAPK, PI3K-AKT and mTOR are found to be regulated by quercetin...

Background: Folate-dependent one-carbon metabolism provides one-carbon units for several biological processes. This pathway is highly compartmentalized in eukaryotes, with the mitochondrial pathway producing formate for use in cytoplasmic processes. The mitochondrial enzyme MTHFD2 has been reported to use NAD+ as a cofactor while the isozyme MTHFD2L utilizes NAD+ or NADP+ at physiologically relevant conditions. Because MTHFD2 is highly expressed in many cancer types, we sought to determine the cofactor preference of this enzyme...

Thermal therapy combined with chemotherapy is one of the advanced and efficient methods to eradicate cancer. In this work, we fabricated magnetically actuated smart textured (MAST) fibrous systems and studied their candidacy for cancer treatment. The polycaprolactone-Fe3 O4 based MAST fibers were fabricated using electrospinning technique. These MAST fibrous systems contained carbogenic quantum dots as a tracking agent and doxorubicin hydrochloride anticancer drug. Additionally, as fabricated MAST fibrous systems were able to deliver anticancer drug and heat energy simultaneously to kill HeLa cells in a 10 min period in vitro...

Colorectal cancer (CRC) is the fourth most common cancer in both men and women in the United States, resulting in over 55,000 deaths annually. Environmental and genetic factors influence the development of CRC, and inflammation is a critical hallmark of cancer that may arise from a variety of factors. Purpose of review: While patients with inflammatory bowel disease (IBD) have a higher risk of developing CRC, sporadic CRCs may engender or be potentiated by inflammation as well. In this review, we focus on recent advances in basic and translational research utilizing murine models to understand the contribution of inflammatory signaling pathways to CRC...

Esophagogastroduodenoscopy for cancer screening was performed in a 55-year-old woman as part of a health screening program, and revealed a depressed lesion approximately 20 mm in diameter in the lesser curvature of the mid-gastric body. Several biopsy specimens were collected as the lesion resembled early gastric cancer; however, histopathologic evaluation revealed chronic active gastritis with an ulcer and amorphous eosinophilic material deposition. Congo red staining identified amyloid proteins, and apple-green birefringence was shown using polarized light microscopy...
