BACKGROUND: Physical activity is associated with a lower risk of disease recurrence among colon cancer survivors. Excess visceral adipose tissue is associated with a higher risk of disease recurrence among colon cancer survivors. The pathways through which physical activity may alter disease outcomes are unknown, but may be mediated by changes in visceral adipose tissue. METHODS: Thirty-nine stage I-III colon cancer survivors were randomised to one of three groups: usual-care control, 150 min wk(-1) of aerobic exercise (low dose) and 300 min wk(-1) of aerobic exercise (high dose) for 6 months...

Phosphaturic mesenchymal tumours are a heterogeneous set of bone and soft tissue neoplasms that can cause a number of paraneoplastic syndromes such as tumour induced osteomalacia. The term phosphaturic comes from the common finding that these tumours secrete high levels of fibroblast growth factor 23 which causes renal phosphate wasting leading to hypophosphatemia. Phosphaturic mesenchymal tumours are rare and diagnosis is difficult. A very active 68 year old male presented with bone pain and muscle weakness...

Background: The use of Traditional Chinese Medicine (TCM) by breast cancer patients is growing. Few studies have examined the complexity of breast cancer survivors' attitudes, lived experiences, barriers, and perceptions in using TCM as part of their treatment journey. This article examines breast cancer survivors' experiences, perceptions of, and benefits (or not) in using TCM. Methods: Qualitative research, using semi-structured interviews, was the chosen methodology. Results: Participants used TCM as a form of self-help and as a complement, not an alternative, to standard care...

There is an increasing evidence for a link between nutrition, lifestyle and prostate cancer (PCa) development and/or progression of disease. The objective of this study was to examine the association between dietary factors and PCa incidence and aggressiveness in a case-control study. After the analysis of the anatomic pathology, subjects were classified in patients with PCa (n = 157) and controls (n = 158). Clinical data including Gleason score, PSA values and biopsy results, were compiled. Frequencies of food consumption and sociodemographic data were also obtained...

PURPOSE: Epigenetic mechanisms may help to explain the complex and heterogeneous relation between sex hormones and cancer. Few studies have investigated the effects of sex hormones on epigenetic markers related to cancer risk such as levels of methylation within repetitive DNA elements. Our objective was to describe the association between endogenous sex hormone exposure and levels of LINE-1 and Alu methylation in healthy postmenopausal women. METHODS: We nested a cross-sectional study within the Alberta Physical Activity and Breast Cancer Prevention Trial (2003-2006)...

BACKGROUND: Increasing physical activity can improve cognition in healthy and cognitively impaired adults; however, the benefits for cancer survivors are unknown. The current study examined a 12-week physical activity intervention, compared with a control condition, on objective and self-reported cognition among breast cancer survivors. METHODS: Sedentary breast cancer survivors were randomized to an exercise arm (n = 43) or a control arm (n = 44). At baseline and at 12 weeks, objective cognition was measured with the National Institutes of Health Cognitive Toolbox, and self-reported cognition using the Patient-Reported Outcomes Measurement Information System scales...

A person living with cancer will potentially have some degree of physical, cognitive, and/or psychological impairment, periods of unemployment, financial concerns, social isolation, and existential questions, any or all of which can impact the family and friends who surround them. In our current era of health care, patients with cancer receive invasive diagnostic studies and aggressive treatment as outpatients, and then convalesce at home. As such, cancer family caregivers are de facto partners with the healthcare team...

Tumors depend on their microenvironment for sustained growth, invasion and metastasis. In this environment, endothelial cells (ECs) are an important stromal cell type interacting with malignant cells to facilitate tumor angiogenesis and cancer cell extravasation. Of note, lysosomal acid lipase (LAL) deficiency facilitates melanoma growth and metastasis. ECs from LAL-deficient (lal-/-) mice possess enhanced proliferation, migration, and permeability of inflammatory cells by activating the mammalian target of rapamycin (mTOR) pathway...

Two-pore channels (TPCs) are endolysosomal cation channels. Two members exist in humans, TPC1 and TPC2. Functional roles associated with the ubiquitously expressed TPCs include VEGF-induced neoangiogenesis, LDL-cholesterol trafficking and degradation, physical endurance under fasting conditions, autophagy regulation, the acrosome reaction in sperm, cancer cell migration, and intracellular trafficking of pathogens such as Ebola virus or bacterial toxins (e.g., cholera toxin). In a genome-wide association study for variants associated with human pigmentation characteristics two coding variants of TPC2, rs35264875 (encoding M484L) and rs3829241 (encoding G734E), have been found to be associated with a shift from brown to blond hair color...

Zinc oxide (ZnO), as a material with attractive properties, has attracted great interest worldwide, particularly owing to the implementation of the synthesis of nano-sized particles. High luminescent efficiency, a wide band gap (3.36eV), and a large exciton binding energy (60meV) has triggered intense research on the production of nanoparticles using different synthesis methods and on their future applications. ZnO nanomaterials can be used in industry as nano-optical and nano-electrical devices, in food packaging and in medicine as antimicrobial and antitumor agents...

The physical nature of the tumor microenvironment significantly impacts tumor growth, invasion and response to drugs. Most in vitro tumor models are designed to study the effects of extracellular matrix (ECM) stiffness on tumor cells, while not addressing the effects of ECM's specific topography. In this study we bioengineered submucosal organoids, using primary smooth muscle cells (SMCs) embedded in collagen I (Col I) hydrogel, which produce aligned and parallel fiber topography similar to those found in vivo...

BACKGROUND: The study of physical activity in cancer survivors has been limited to one cause, one effect relationships. In this exploratory study, we used recursive partitioning to examine multiple correlates that influence physical activity compliance rates in cancer survivors. METHODS: African American breast cancer survivors (N = 267, Mean age = 54 years) participated in an online survey that examined correlates of physical activity. Recursive partitioning (RP) was used to examine complex and nonlinear associations between sociodemographic, medical, cancer-related, theoretical, and quality of life indicators...

N,N'-methylenebis(acrylamide) (MBA)-crosslinked poly(acrylic acid) (PAA) particles with low degree of crosslinking were synthesized using distillation precipitation polymerization (DPP). Size and size distribution of particles were obtained using DLS and FE-SEM and results showed that microspheres had a narrow size dispersity. (1) H NMR results indicated that amount of crosslinker in structure of particles is a little more than the molar percentage of feeded MBA due to greater activity ratio of MBA than AA...

The influence of lifestyle factors on survival following a diagnosis of colorectal cancer (CRC) is not well established. We examined associations between lifestyle factors measured before diagnosis and CRC survival. The Melbourne Collaborative Cohort Study collected data on alcohol intake, cigarette smoking and physical activity, and body measurements at baseline (1990-94) and wave 2 (2003-07). We included participants diagnosed to 31 August 2015 with incident stage I-III CRC within 10-years post exposure assessment...

Genome-wide association studies (GWAS) for BMI, waist-to-hip ratio, and other adiposity traits have identified more than 300 single-nucleotide polymorphisms (SNPs). Although there is reason to hope that these discoveries will eventually lead to new preventive and therapeutic agents for obesity, this will take time because such developments require detailed mechanistic understanding of how an SNP influences phenotype (and this information is largely unavailable). Fortunately, absence of functional information has not prevented GWAS findings from providing insights into the biology of obesity...

OBJECTIVES: While the risk of developing colorectal cancer increases with age, there are limited prospective data regarding best treatment in the older adult population. We launched a phase III trial to evaluate difference in treatment outcome for older adults (aged ≥70years) with advanced colorectal cancer. Here we review the challenges faced and reasons for poor accrual to N0949. MATERIALS AND METHODS: We describe the conceptualization, development and limited results of N0949, a randomized phase III study of fluoropyrimidine/bevacizumab with or without oxaliplatin (mFOLFOX7 or XELOX) as first line chemotherapy for metastatic colorectal cancer...

Patients with cancer are experiencing long-term survival following chemotherapy, but the treatment may also be associated with short and long-term toxicity, including the possibility of cognitive dysfunction. A literature overview indicated a significant association between chemotherapy and cognitive impairment but prospective longitudinal research is warranted to examine the degree and persisting nature of this decline. Although chemotherapeutic agents are unlikely to cross the blood-brain barrier, it has been alleged that the occurrence of neurotoxicity is linked to the pro-inflammatory cytokine pathways...
