To the best of our knowledge, only two studies analyzed the relationship between HRV and carcinoembryonic antigen (CEA) in colon cancer patients. The aim of this study was to analyze changes in the autonomic activity of colon cancer patients using heart rate variability (HRV) and blood pressure variability (BPV) measures, and to verify if HRV and BPV parameters correlate with hemodynamic indices in this group (…) and the plasma levels of CEA. Presence of colon cancer is associated with changes in autonomic activity, namely parasympathetic-sympathetic imbalance in form of sympathetic overdrive...

The role of local treatment in patients with oligometastatic non-small-cell lung cancer (NSCLC) is a subject of ongoing debate. This study assessed the survival impact of combined surgery to the primary tumor and metastatic disease in the management of metastatic NSCLC. Stage IV NSCLC patients at presentation, diagnosed from 2004 to 2013 were identified from the SEER (Surveillance, Epidemiology, and End Results) database. Propensity-matched analysis was performed considering baseline characteristics (age, gender, race, histology, TN stage, and site of metastases)...

NSUN2 is a tRNA methyltransferase and plays an important role in cell development via modifying RNA methylation. We aimed to evaluate the expression of NSUN2 and its prognostic value in HNSCC. Random-effects model of meta-analysis shows 1.99-folds (95% CI: 1.89-2.09) upregulation of NSUN2 expression in HNSCC versus normal tissues. Patients with high NSUN2 levels had approximately 22 months shorter overall survival, and had a higher mortality risk than those with low one (p-trend = 0.020). In conclusion, NSUN2 is a potential independent prognostic marker and may be a potential therapeutic target in HNSCC...

Reducing the dimension of antigen-binding proteins to an only immunoglobulin domain has been one of the objectives of antibody manufacturing. Heavy chain antibodies were encountered while attempting to separate the blood serum proteins of dromedaries. Later the term "nanobodies" (Nbs) was introduced. The advantageous features of Nbs comprise little immunogenicity, stability at low/high pH, capacity to target antigens that are less antigenic, and, lastly, easy capability to be used for therapy against tumor cells...

BACKGROUND: Human epidermal growth factor recptor-2 (HER2) was identified as a driver gene in several types of cancers with both prognostic and predictive value. However, the molecular association of HER2 gene mutation with HER2 gene amplification and/or protein expression in cancer tissues has not been clearly defined. Moreover, there is little information available on HER2 status role in tumor progression and metastasis in colorectal carcinoma (CRC) compared to other solid tumors. The aim of this study was to evaluate both HER2 amplification and protein expression profiles using immunohistochemistry (IHC) and bright-field dual in situ hybridization (BDISH) techniques, respectively...

Polymorphism of the calcium-sensing receptor gene (CaSR or CaR) has been associated with an increased risk for breast cancer. This receptor plays an important role in calcium homeostasis, and has also been detected in several tissues that are unrelated to calcium metabolism, such as the skin, brain, and breast. The calcium-sensing receptor on cellular level, it regulates cell differentiation, proliferation, cell death, and gene expression. In breast cancer cells, CaSR seems to stimulate secretion of the parathyroid hormone-related protein (PTHrP), which stimulates cellular proliferation...

Oncolytic measles and mumps viruses (MeV, MuV) have a potential for anti-cancer treatment. We examined the anti-tumor activity of MeV, MuV, and MeV-MuV combination (MM) against human solid malignancies (HSM). MeV, MuV, and MM targeted and significantly killed various cancer cell lines of HSM but not normal cells. MM demonstrated a greater anti-tumor effect and prolonged survival in a human prostate cancer xenograft tumor model compared to MeV and MuV. MeV, MuV, and MM significantly induced the expression of immunogenic cell death markers and enhanced spleen-infiltrating immune cells...

Primary malignant glioma cell lines are being used for initial screening of anticancer agents. We utilized a simple mechanical disaggregation method for deriving cell lines from tumor tissues; and a Coverslip Culture-Acridine Orange Staining method to study cellular damage. Cell lines could be grown for up to three passages within three weeks after surgery. Cell proliferation, total cellular damage, and MTT assay were studied as parameters of cytotoxic response. Frequencies of damaged cells varied in different cell lines; and increased after cytotoxic treatments under clinically relevant conditions...

Predictive biomarkers and prognostic models are required to identify recurrent grade III glioma patients who benefit from existing treatment. In this study of 62 recurrent grade III glioma patients, a range of clinical and paraclinical factors are tested for association with progression-free survival, overall survival, and response to bevacizumab and irinotecan therapy. Significant factors from univariate screening are included in multivariate analysis. Biomarkers previously advanced as predictive or prognostic in the first-line setting did not affect outcome in this patient cohort...

Molecular imaging and therapy is a rapidly evolving field in research and clinical medicine. The use of the exciting and attractive properties of radioisotopes for imaging and therapy has made Nuclear Medicine very significant when it comes to molecular imaging/therapy. Monoclonal Antibodies (mAbs) on the other hand are very important targeting biomolecules with high affinity that can "carry" the radioisotope of choice. Herein we make a brief overview of the radiolabeled mAbs that target prostate specific membrane antigen (PSMA) and their use in the management of patients with prostate cancer (PCa)...
