The alternation of resorption of preexisting bone by the osteoclasts followed by de novo bone formation by osteoblasts is called bone modeling during childhood and bone remodeling during adulthood. A central question raised by this physiological process that is fundamental to longitudinal growth during childhood and adolescence and that is attacked at the other end of life in the context of osteoporosis is to know how it is regulated. This question was rejuvenated in the late 1990s and early 2000s years when the application of mouse genetics made it feasible to test whether there were new endocrine determinants of bone (re)modeling. Addressing this question, taking into account fundamental cell biology features of bone led to the hypothesis that there should be a coordinated control of bone growth/mass, energy metabolism, and reproduction. Testing genetically and molecularly, this hypothesis revealed that, in vivo, the adipocyte-derived hormone leptin is a powerful inhibitor of bone mass accrual following its signaling in the brain. This chapter details the molecular bases and biological relevance of this regulation of bone mass accrual by leptin.The tendency of edifenphos (EDF) species toward boron carbide nanotube (BC3NT) was investigated through density functional theory (DFT) calculations with perfect and defected forms. It was found that perfect BC3NT tube is not capable to adsorb the EDF molecules appropriately. Introducing defects in BC3NT lattice resulted in a noticeable enhancement of interaction with EDF providing the adsorption energy of - 25.66 kcal/mol. It was predicted that the conductivity of complex formed of single vacancy BC3NT tube, SV-BC3NT, and EDF complexes is enhanced by 91.37 times compared with BC3NT tube with no defects. As the solvent dielectric constant increases, a significant change in adsorption energy was reported while slighter variation was observed at dielectric constant values lower than 15. Similar to electric conductivity, the magnetic properties of BC3NT are remarkably enhanced after single vacancy defect and EDF adsorption leads to a highly significant change in magnetic property compared with perfect BC3NT. find more Graphical abstract.Highly sensitive non-contact mode temperature sensing is substantial for studying fundamental chemical reactions, biological processes, and applications in medical diagnostics. Nanoscale-based thermometers are guaranteeing non-invasive probes for sensitive and precise temperature sensing with subcellular resolution. Fluorescence-based temperature sensors have shown great capacity since they operate as "non-contact" mode and offer the dual functions of cellular imaging and sensing the temperature at the molecular level. Advancements in nanomaterials and nanotechnology have led to the development of novel sensors, such as nanothermometers (novel temperature-sensing materials with a high spatial resolution at the nanoscale). Such nanothermometers have been developed using different platforms such as fluorescent proteins, organic compounds, metal nanoparticles, rare-earth-doped nanoparticles, and semiconductor quantum dots. Carbon dots (CDs) have attracted interest in many research fields because of outstanding properties such as strong fluorescence, photobleaching resistance, chemical stability, low-cost precursors, low toxicity, and biocompatibility. Recent reports showed the thermal-sensing behavior of some CDs that make them an alternative to other nanomaterials-based thermometers. This kind of luminescent-based thermometer is promising for nanocavity temperature sensing and thermal mapping to grasp a better understanding of biological processes. With CDs still in its early stages as nanoscale-based material for thermal sensing, in this review, we provide a comprehensive understanding of this novel nanothermometer, methods of functionalization to enhance thermal sensitivity and resolution, and mechanism of the thermal sensing behavior.Merkel cell carcinoma (MCC) is an uncommon aggressive cutaneous neuroendocrine tumor with high mortality. The purpose of this study is to describe the clinical correlates of MCC and identify changing trends over time using a retrospective chart review of 113 cases in a single tertiary center pathology database from 1997 to 2015. MCC occurred mostly in the elderly (median age 77 years), more often in males (n = 60, 53%), was most commonly located on the head and neck region (n = 63, 56%), and most commonly presented on the left side of the body (n = 59, 52%). Overall, there was an increase in MCC diagnoses per year from 1997 to 2015, with 2.3 times more cases diagnosed in the last 3 years of the study period than in the first 3 years. Furthermore, cases diagnosed after 2008 were more likely to occur in younger patients, less than or equal to 77 years of age (OR 2.32, 95% CI 1.08, 4.97, p = 0.04). The median age of diagnosis among females was 76 years and among males was 74 years. There was no change in the overall age of diagnosis among men and a decrease in age of diagnosis among females during the study. There was an overall increase in the MCC cases diagnosed among women, and a slight increase in the proportion of females affected by MCC throughout the course of the study. This retrospective case series elucidates MCC epidemiologic characteristics and describes how incidence, sex, and age at diagnosis have changed over the course of the study.
Purpose of this retrospective data analysis was to depict the effects of astructured off-season conditioning program with breast cancer survivors competing in dragon boat paddling.

In this study 10 breast cancer survivors (mean age 52.0 ± 5.4years) who had finished the primary cancer treatment and who were paddlers of the Vienna Pink Dragon self-help group underwent astructured 10-week exercise program as part of their routine supportive treatment. Upper extremity strength, endurance capacity, shoulder flexibility, quality of life and work ability were assessed at baseline and after completion of the exercise program.

Out of 10 patients 8 completed more than 80% of the exercise sessions. Amultivariate analysis of variance (MANOVA) of the pooled exercise effects showed avery large effect size (Η
 = 0.982); however, the change from baseline to follow-up was non-significant (p = 0.363). In the European Organisation for Research and Treatment of Cancer Quality of Life of Cancer Patients Questionnaire (EORTC QLQ-C30) the exercise program led to asignificant improvement of body image (p = 0.
