Although the cases of endometrial carcinoma (EC) is gradually increasing across the world, its etiology and pathogenesis remain unknown. The present study is the first to define the role and biological function of circRNA hsa_circ_0075960 in the development and progression of EC. We first determined that hsa_circ_0075960 is aberrantly expressed in EC cells. Then, we uncovered that the downregulation of hsa_circ_0075960 suppressed cell proliferation and promoted cell apoptosis of EC cells, suggesting that hsa_circ_0075960 could inhibit the progression of EC in vitro. In addition, we identified that miR-361-3p was the direct target of hsa_circ_0075960. Further analysis revealed that hsa_circ_0075960 affected the development of EC via sponging miR-361-3p. Interestingly, we verified that the level of SH2B1 was controlled by the downregulation of hsa_circ_0075960 and that the negative effect caused by hsa_circ_0075960 could be reversed via miR-361-3p inhibition. Our cumulative results revealed that the novel tumor regulator hsa_circ_0075960 functioned as a sponge for miR-361-3p/SH2B1 in EC cells and regulated the progression of EC through the modulation of miR-361-3p.
  Both 2009 pandemic influenza A (H1N1) and SARS-CoV-2 are transmitted by respiratory secretions and in severe cases result in a viral pneumonitis, requiring intensive care unit (ICU) admission. However, no studies have compared the clinical characteristics and outcomes of such patients.
 
  To report and compare the demographic characteristics, treatments, use of critical care resources, and outcomes of patients admitted to an Australian ICU with H1N1 influenza during the winter of 2009, and SARS-CoV-2, during the winter of 2020.
 
  This was a multicentre project, utilizing national data from previous and ongoing epidemiological studies concerning severe acute respiratory infections in Australia. All ICUs admitting patients with H1N1 or COVID-19 were included and contributed data. We compared clinical characteristics and outcomes of H1N1 patients admitted to ICU in the winter of 2009 vs COVID-19 patients admitted to ICU in the winter of 2020. The primary outcome was in-hospital mortality. Potential years of lif mortality was similar, but because of demographic differences in affected patients, deaths due to 2009 H1N1 influenza led to an 11-fold increase in the number of PYLL in critically ill patients.
 In comparison to 2009 H1N1 influenza, COVID-19 admissions over winter in Australia resulted in fewer ICU admissions, and lower bed-day occupancy. Crude in-hospital mortality was similar, but because of demographic differences in affected patients, deaths due to 2009 H1N1 influenza led to an 11-fold increase in the number of PYLL in critically ill patients.
  The improved survival of patients even with metastatic cancer has led to an increase in the incidence of spine metastases, suggesting the need for a more aggressive palliative treatment than conventional external beam radiation therapy (cEBRT). Consequently, spinal stereotactic body radiation therapy (SBRT) has increased in popularity over the past decade. However, there has been no comparison of patterns of usage of cEBRT versus SBRT in the treatment of spinal metastases in the US.
 
  The National Cancer Data Base (NCDB) from 2004-2013 was used for analysis. cEBRT was defined as 30 Gy in 10 fractions, 20 Gy in 5 fractions, or 8 Gy in 1 fraction. SBRT was defined as 25-32 Gy infive5 fractions, 24-32 Gy in 4 fractions, 20-32 Gy in three fractions, 14-32 Gy in 2 fractions, or 14-24 Gy in 1 fraction. Single and multivariable associations between patient demographic and cancer characteristics and type of radiation were performed.
 
  From 2004-2013, 23,181 patients with spinal metastases in the United States receigation.
 Most patients with spine metastases were treated with cEBRT, usually with 10 fractions. Receipt of SBRT was significantly associated with race, insurance, geography, population, type of treatment facility, and year of diagnosis, even after controlling for other factors. These findings raise questions about disparities in access to and delivery of care that deserve further investigation.Physical inactivity influences the development of muscle insulin resistance yet is far less understood than diet-induced muscle insulin resistance. Progress in understanding the mechanisms of physical inactivity-induced insulin resistance is limited by a lack of an appropriate preclinical model of muscle insulin resistance. Here, we discuss differences between diet and physical inactivity-induced insulin resistance, the advantages and disadvantages of the available rodent inactivity models to study insulin resistance, and our current understanding of the mechanisms of muscle insulin resistance derived from such preclinical inactivity designs. The burgeoning rise of health complications emanating from metabolic disease presents an alarming issue with mounting costs for health care and a reduced quality of life. There exists a pressing need for more complete understanding of mechanisms behind the development and progression of metabolic dysfunction.  https://www.selleckchem.com/products/PP242.html  Since lifestyle modifications such as poor diet and lack of physical activity are primary catalysts of metabolic dysfunction, rodent models have been formed to explore mechanisms behind these issues. Particularly, the use of a high-fat diet has been pervasive and has been an instrumental model to gain insight into mechanisms underlying diet-induced insulin resistance (IR). However, physical inactivity (and to some extent muscle disuse) is an often overlooked and much less frequently studied lifestyle modification, which some have contended is the primary contributor in the initial development of muscle IR. In this mini-review we highlight some of the key differences between diet- and physical inactivity-induced development of muscle IR and propose reasons for the sparse volume of academic research into physical inactivity-induced IR including infrequent use of clearly translatable rodent physical inactivity models.In 11 healthy adults (25 ± 4 yr; 2 female, 9 male subjects), we investigated the effect of expiratory resistive loaded breathing [65% maximal expiratory mouth pressure (MEP), 15 breaths·min-1, duty cycle 0.5; ERLPm] on mean arterial pressure (MAP), leg vascular resistance (LVR), and leg blood flow ([Formula see text]). On a separate day, a subset of five male subjects performed ERL targeting 65% of maximal expiratory gastric pressure (ERLPga). ERL-induced expiratory muscle fatigue was confirmed by a 17 ± 5% reduction in MEP (P less then 0.05) and a 16 ± 12% reduction in the gastric twitch pressure response to magnetic nerve stimulation (P = 0.09) from before to after ERLPm and ERLPga, respectively. From rest to task failure in ERLPm and ERLPga, MAP increased (ERLPm = 31 ± 10 mmHg, ERLPga = 18 ± 9 mmHg, both P less then 0.05), but group mean LVR and [Formula see text] were unchanged (ERLPm LVR = 0.78 ± 0.21 vs. 0.97 ± 0.36 mmHg·mL-1·min, [Formula see text] = 133 ± 34 vs. 152 ± 74 mL·min-1; ERLPga LVR = 0.70 ± 0.
