Blockage of immune checkpoint molecules increases T cell priming potential of dendritic cell vaccine.
In this study, we silenced the expression of PD-L1 in DCs and PD-1 in T cells by siRNA-loaded chitosan-dextran sulfate nanoparticles (NPs) and evaluated the DC phenotypic and functional characteristics and T cells functions following tumor antigen recognition on DCs, ex vivo. Our results showed that synthesized NPs had good physicochemical characteristics (size of 77.5 nm and zeta potential of 14.3) that was associated with efficient cellular uptake and target gene silencing. Moreover, PD-L1 silencing...

Evaluating the sensitivity of Halcyon's automatic transit image acquisition for treatment error detection: A phantom study using static IMRT.
CONCLUSIONS: Rapid analyses of automatically acquired Halcyon™ exit images could detect mid-treatment changes with high sensitivity, though appropriate thresholds will need to be set. This study presents the first steps toward developing effortless image evaluation for all aspects of every patient's treatment.

Inflammatory markers in cancer: Potential resources.
Authors: Chauhan R, Trivedi V Abstract Cancer is a leading cause of death worldwide and a major burden on developing and less developed countries of the world with limited resources for prevention and effective treatment of cancer. Although cancer is multifactorial in origin, various epidemiological and experimental studies suggest that chronic inflammation has an important role in all stages of cancer, from initiation to progression and even survival of the patient.

Neuroprotective effects of resveratrol in Alzheimer's disease.
Authors: Rao YL, Ganaraja B, Joy T, Pai MM, Ullal SD, Murlimanju BV Abstract Alzheimer's disease (AD) is a neurodegenerative disorder, which is commonly seen in older individuals. This is characterized by cognitive dysfunction, which leads to dementia. Pharmacological treatments for AD are mainly targeted on its symptoms like memory loss and cognitive impairment. The pathophysiology involved in AD is intra-neuronal accumulation of hyper-phosphorylated tau protein as neurofibrillary tangle...

Role of miRNA clusters in epithelial to mesenchymal transition in cancer.
Authors: Shukla V, Adiga D, Jishnu PV, Varghese VK, Satyamoorthy K, Kabekkodu SP Abstract Epithelial to mesenchymal transition (EMT) is a multistep biological process in which epithelial cells acquire characteristics of mesenchymal cells. Inappropriate activation of EMT contributes to the acquisition of pro-metastatic characteristics and cancer progression. EMT process involves the downregulation of epithelial markers (EpCAM, CDH1) and upregulation of mesenchymal markers (VIM, CDH2) and...

Ferrocene is a potent organometallic which have been hybridized with other compounds resulting in compounds with enhanced biological activity such as antimalarial and anticancer. Drugs such as ferroquine were developed from ferrocene and chloroquine. It was tested in the 1990s as an antimalarial...

Unilateral phrenic nerve stimulation in the therapeutical algorithm of central sleep apnoea in heart failure
Purpose of review Central sleep apnoea (CSA) is highly prevalent in patients with heart failure and substantially impairs survival. If optimal cardiac treatment fails, alternative therapeutical options, including positive airway pressure (PAP) therapies, drugs or application of oxygen and carbon dioxide are considered to suppress CSA which interfere with the complex underlying pathophysiology. Most recently, unilateral phrenic nerve stimulation (PNS) has been studied in these patients. Therefore,...

Editing of the gut microbiota reduces carcinogenesis in mouse models of colitis-associated colorectal cancer
Chronic inflammation and gut microbiota dysbiosis, in particular the bloom of genotoxin-producing E. coli strains, are risk factors for the development of colorectal cancer. Here, we sought to determine whether precision editing of gut microbiota metabolism and composition could decrease the risk for tumor development in mouse models of colitis-associated colorectal cancer (CAC). Expansion of experimentally introduced E. coli strains in the azoxymethane/dextran sulfate sodium colitis model was driven...

Specific targeting of CD163+ TAMs mobilizes inflammatory monocytes and promotes T cell-mediated tumor regression
Tumor-associated macrophages (TAMs) play critical roles in tumor progression but are also capable of contributing to antitumor immunity. Recent studies have revealed an unprecedented heterogeneity among TAMs in both human cancer and experimental models. Nevertheless, we still understand little about the contribution of different TAM subsets to tumor progression. Here, we demonstrate that CD163-expressing TAMs specifically maintain immune suppression in an experimental model of melanoma that is resistant...

Digital versus light microscopy assessment of extraprostatic extension in radical prostatectomy samples
AbstractFocal or non-focal/extensive extraprostatic extension of prostate carcinoma is an important pathologic prognostic parameter to be reported after radical prostatectomy. Currently, there is no agreement on how to measure and what are the best cutoff points to be used in practice. We hypothesized that digital microscopy would potentially provide more objective measurements of extraprostatic extension, thus better defining its clinical significance. To further our knowledge on digital prostate...

Squamous cell carcinoma (SCC) of the head and neck is the sixth most common cancer worldwide. It is preceded by early asymptomatic lesions which, if identified early enough and removed, would prevent malignant transformation or avoid delaying diagnosis to advanced stages. Our aim was to evaluate the feasibility of a screening programme for SCC of the head and neck in a group of high-risk patients, and to investigate their addiction profile.
