system proposed here may help to define the optimum technique of treatment, prognosis, and comparison of outcome results. OBJECTIVE The aim of the study was to examine subjective sleep quality in a population of healthy volunteers and its association with evening and night light exposure to screens of media devices. METHODS A total of 693 participants (mean age 31.2±11.4 years, 159 men, and 538 women) completed an online questionnaire battery consisting of several sleep-related questionnaires PSQI, FSS, MCTQ, MEQ, and added questions assessing the timing and character the evening and night exposure to electronical devices (TV, PC, tablets, and phones), and the use of various filters blocking short-wavelength light. RESULTS Statistical analyses show that longer cumulative exposure to screen light in the evening was associated with greater sleep inertia in the morning (p=0.019, η2=0.141) and longer sleep latency on workdays (p=0.038, η2=0.135). Furthermore, exposure to screen light 1.5 h before sleep or during night awakenings was also associated with a decreased chance to wake up before alarm clock (p=0.003, d=0.30), larger social jet lag (p less then 0.001, d=0.15), more daytime dysfunction (p less then 0.001, d=0.40), decreased subjective sleep quality (p=0.024, d=0.16), and more fatigue (p less then 0.001, d=0.52). A statistical trend for an increase in duration of sleep on weekdays (p=0.058, d=0.23) was also found in participants using blue-light filters in the evening hours. DISCUSSION Our results are in line with other studies that converge to show the negative association of evening and night exposure to short-wavelength light on subjective and objective sleep parameters. DHFR inhibitor Results suggest that light hygiene in general population should be given more attention not only in the context of clinical sleep medicine but also in the realm of public health. Arsenic is an endocrine disruptor that promotes breast cancer (BCa) development. Estrogen synthesis, through aromatase activation, is essential for BCa promotion and progression through activating the G-coupled estrogen receptor 1 (GPER1), regulating rapid nongenomic effects involved in cell proliferation and migration of BCa cells. Herein, was studied the role of aromatase activation and the GPER1 pathway on sodium arsenite-induced promotion and progression of MDA-MB-231 and MDA-MB-453 BCa cell lines. Our results demonstrated that 0.1 μM of sodium arsenite induces cell proliferation, migration, invasion, and stimulates aromatase activity of BCa cell lines MDA-MB-231, MDA-MB-453, MCF-7, but not in a nontumorigenic breast epithelial cell line (MCF-12A). Using letrozole (an aromatase inhibitor) and G-15 (a GPER1-selective antagonist), we demonstrated that sodium arsenite-induced proliferation and migration is mediated by induction of aromatase enzyme and, at least in part, by GPER1 activation in MDA-MB-231 and MDA-MB-453 cells. Sodium arsenite induced phosphorylation of Src that participated in sodium arsenite-induced aromatase activity, and -cell proliferation of MDA-MB-231 cell line. Overall, data suggests that sodium arsenite induces a positive-feedback loop, resulting in the promotion and progression of BCa cells, through induction of aromatase activity, E2 production, GPER1 stimulation, and Src activation. Cyclophosphamide (CP) is widely used as chemotherapy in various cancers; however, testicular atrophy has been encountered as an associated adverse effect. Oxidative stress, enhanced endoplasmic reticulum (ER) stress, and subsequent apoptosis are involved in the molecular mechanisms of CP-induced testicular toxicity. In addition to the cardiovascular benefits of LCZ696 (sacubitril/valsartan (VAL)), neprilysin inhibition was shown to mediate Ca2+ sequestration inside the ER. Furthermore, long noncoding RNA taurine-upregulated gene 1 (lncRNA TUG1) was shown to ameliorate apoptosis in various diseases. This tempted us to investigate the possible benefit of LCZ696 against CP-induced testicular dysfunction in rats through neprilysin inhibition axis, and the downstream apoptotic cascade, with highlighting the impact of lncRNA TUG1 in regulating testicular toxicity. Sixty adult male Wistar rats were randomly allocated as control, LCZ696, VAL, CP, CP + LCZ696, and CP + VAL. Testicular atrophy was induced by single-dose injection of CP (200 mg/kg; i.p.). LCZ696 treated group received LCZ696 (30 mg/kg; p.o.) for 6 days, with CP (200 mg/kg; i.p.) single-dose on day 5. LCZ696 increased lncRNA TUG1 expression, improved sperm characteristics, hormonal profile, testicular function, antioxidant defences, and Bcl-2. The histopathological picture and reduced oxidative and ER stress markers, aligned with declined Bax, caspase-3 and the expression of CHOP, PUMA, Noxa, Bim, and p53, with a subtle superior effect over VAL-treated group. In conclusion, the current study highlights the promising impact of LCZ696 in ameliorating chemotherapy-induced testicular atrophy; yet, further investigation regarding longer duration and different doses of LCZ696 is warranted. Diabetic foot ulcers (DFUs) are one of the most serious complications of diabetes mellitus (DM). Although research has improved understanding of DFU etiology, an effective clinical prevention and management of DFUs remains undetermined. Knowledge of recent technologies may enable clinicians and researchers to provide appropriate interventions to prevent and treat DFUs. This paper discusses how diabetes causes peripheral neuropathy and peripheral arterial diseases, which contribute to increased risk of DFUs. Then, emerging technologies that could be used to quantify risks of DFUs are discussed, including laser Doppler flowmetry for assessing plantar tissue viability, infrared thermography for early detection of plantar tissue inflammation, plantar pressure and pressure gradient system for identification of specific site at risk for DFUs, and ultrasound indentation tests (elastography) to quantify plantar tissue mechanical property. This paper also reviews how physical activity reduces risks of DFUs and how technology promotes adherence of physical activity. The clinician should encourage people with DM to exercise (brisk walking) at least 150 min per week and assess their exercise log along with the blood glucose log for providing individualized exercise prescription. Last, rehabilitation interventions such as off-loading devices, thermotherapy and electrotherapy are discussed. Although the exact etiology of DFUs is unclear, the emerging technologies discussed in this paper would enable clinicians to closely monitor the change of risk of DFUs and provide timely intervention. An integrated approach using all these emerging technologies should be promoted and may lead to a better outcome of preventing and managing DFUs.
