Drug screening is currently demanding for realistic models that are able to reproduce the structural features of solid tumors. 3D cell culture systems, namely spheroids, emerged as a promising approach to provide reliable results during drug development. So far, Liquid Overlay Technique (LOT) is one of the most used methods for spheroids assembly. It comprises cellular aggregation due to their limited adhesion to certain biomaterials, like agarose. However, researchers are currently improving this technique in order to obtain spheroids on surfaces that mimic cancer extracellular matrix (ECM), since cell-ECM interactions modulate cells behavior and their drug resistance profile...

BACKGROUND AND OBJECTIVES: Due to the increasing number of elderly and an increase in the number of cases of cancer by age, cancer is a common problem in the elderly. For elderly patients with cancer, the disease and its treatment can have long-term negative effects on their quality of life (QoL). The purpose of this study was to evaluate the effect of progressive muscle relaxation, body image and deep diaphragmatic breathing on the QoL in the elderly with cancer. MATERIALS AND METHODS: This study was a randomized controlled trial in which 50 elderly patients with breast or prostate cancer were randomized into study and control groups...

Pepsinogen C (PGC) belongs to the aspartic protease family and is secreted by gastric chief cells. PGC could be activated to pepsin C and digests polypeptides and amino acids, but as a zymogen PGC's functions is unclear. In normal physiological conditions, PGC is initially detected in the late embryonic stage and is mainly expressed in gastric mucosa. The in situ expression of PGC in gastric mucosa is decreased considerably in the process of superficial gastritis → atrophic gastritis → gastric cancer (GC), proving that PGC is a comparatively ideal negative marker of GC...

Evidence suggests an association between inflammation and depression, although findings are mixed. Focusing on core processes in depression may clarify associated biological underpinnings. Negative cognitive bias is a key component of depression, but has not been examined in relation to inflammation. Thus, we tested the hypothesis that elevated inflammatory markers would be associated with negative attentional bias in a sample of 91 breast cancer survivors. Participants were drawn from a larger study and provided blood samples for assessment of peripheral markers of inflammation and completed questionnaires and neuropsychological testing...

Clinical use of camptothecin (CPT) is hindered due to its poor water and oil solubility, active lactone ring instability and non-targeted toxicity. Recently we reported formulation of camptothecin microemulsions with increased solubility for the improved treatment of breast cancer. In this research chitosan stabilized camptothecin nanoemulsions (CHI-CPT-NEs) were formulated improve the cancer targeting efficiency of CPT. The developed NEs were characterized for their droplet size distribution, stability in plasma and evaluated for in-vitro drug release, in-vivo targeting potential, in-vitro hemolytic potential, cytotoxicity, genotoxicity and in-vivo biodistribution...

BACKGROUND: Studies addressing the organizational contexts of care that may help increase the patients' ability to cope with a disease and to navigate through the health care system are still rare. Especially instruments allowing the assessment of such organizational efforts from the patients' perspective are missing. The aim of our study was to develop a survey instrument assessing organizational health literacy (HL) from the patients' perspective, i. e., health care organizations' responsiveness to patients' individual needs...

BACKGROUND: Immigration to the Nordic countries has increased in the last decades and foreign-born inhabitants now constitute a considerable part of the region's population. Several studies suggest poorer self-reported health among foreign-born compared to natives, while results on mortality and life expectancy are inconclusive. To date, few studies have summarized knowledge on mortality differentials by country of birth. This article aims to systematically review previous results on all-cause and cause-specific mortality by country of birth in the Nordic countries...

BACKGROUND: Terminal duct lobular unit (TDLU) involution is a physiological process of breast tissue aging characterized by a reduction in the epithelial component. In studies of women with benign breast disease, researchers have found that age-matched women with lower levels of TDLU involution are at increased risk of developing breast cancer. We previously showed that breast cancer cases with core basal phenotype (CBP; estrogen receptor negative [ER(-)], progesterone receptor-negative [PR(-)], human epidermal growth factor receptor 2-negative [HER2(-)], cytokeratins (CK 5 or CK5/6)-positive [CK5/6(+)] and/or epidermal growth factor receptor-positive [EGFR(+)]) tumors had significantly reduced TDLU involution compared with cases with luminal A (ER(+) and/or PR(+), HER2(-), CK5/6(-), EGFR(-)) tumors from a population-based case-control study in Poland...

Antibodies that antagonize cell signaling pathways specific to their targeted receptor are invaluable tools to study and treat malignancies, but their utility is limited by high production costs and treatment dosages. Researchers have shown that antibodies conjugated to nanoparticles display increased affinity for their target relative to freely delivered antibodies due to multivalency, and this study investigates how this multivalency can enable antibody-nanoparticle conjugates to inhibit oncogenic cell signaling more effectively than freely delivered antibodies...

Mechanical biomarkers associated with cytoskeletal structures have been reported as powerful label-free cell state identifiers. In order to measure cell mechanical properties, traditional biophysical (e.g., atomic force microscopy, micropipette aspiration, optical stretchers) and microfluidic approaches were mainly employed; however, they critically suffer from low-throughput, low-sensitivity, and/or time-consuming and labor-intensive processes, not allowing techniques to be practically used for cell biology research applications...

Gold nanoparticles have been of great interest due to their unique optical properties, facile synthesis and conjugation. Among various shapes of gold nanoparticles, gold nanorods have been widely studied. They can be conjugated with different molecules for biomedical applications, such as tumor imaging and therapy. However, few researchers have studied the anti-tumor properties of bare gold nanorods. In this study, unfunctionalized gold nanorods were synthesized and tested on breast tumor cells. Results showed that the aspect ratio of gold nanorods could be easily influenced by both reaction time and the amount of silver nitrate in the growth solution...

Well-prepared and preserved freshly frozen specimens are indispensable materials for clinical studies. To manage specimen quality and to understand the factors potentially affecting specimen quality during preservation processes, we analyzed the quality of RNA and genomic DNA of various tissues collected between 2002 and 2011 in Linkou Chang Gung Memorial Hospital, Taiwan. During this period, a total of 1059 freshly frozen specimens from eight major cancer categories were examined. It was found that preservation duration, organ origin, and tissue type could all influence the quality of RNA samples...

In 2007, the International Agency for Research on Cancer declared shift work involving circadian disruption to be a "probable" carcinogen (group 2A), noting that human evidence was limited. This study examined associations between rotating night shift work and breast cancer risk in two prospective cohorts, the Nurses' Health Studies (NHS: 1988-2012, n = 78,516; NHS2: 1989-2013, n = 114,559), with 9,541 incident invasive breast malignancies and 24 years of follow-up. Women in NHS with 30+ years of shift work had no increased risk of breast cancer (Hazard ratio (HR) = 0...

Cancer drug researchers have been seeking microtubule-inhibiting agents (MIAs) with higher bioactivity and lower toxicity than currently marketed drugs. WX-132-18B, a novel structural compound synthesized at our institute, specifically bound to the colchicine-binding site on tubulin rather than the vinblastine site, and concentration-dependently reduced microtubule content via depolymerization. It exhibited the same cellular phenotypic profiles as the classic MIAs (colchicine, vincristine, and taxol), including inducing cell cycle arrest at the G2/M phase, triggering tumor cell apoptosis, promoting nuclear membrane permeability, reducing mitochondrial membrane potential, and disrupting the redox system balance...

BACKGROUND: The introduction of adjuvant chemotherapy following surgery for early breast cancer (BC) and its integration into routine clinical practice has consistently improved clinical outcomes. Since the addition of other agents to the contemporary standard of care containing an anthracycline, cyclophosphamide and a taxane has not lead to further prolongation of survival, subsequent efforts concentrated on escalating the administered doses and reducing the time interval between chemotherapy cycles...
