The identified parameters of the standard linear solid model by regarding the influence of the initial ramp for the gel-type material are within an acceptable range for the viscoelastic properties of the calf heart tissue. These results show that the gel-type material has the potential to represent the cardiac muscle in the leadless pacemaker experimental studies. Dynamic mechanical analysis is used to characterize the dynamic viscoelastic properties for the gel by utilizing the identified parameters with taking into account the initial ramp in the frequency domain. Results show that Storage modulus, Loss modulus, and Loss tangent are strongly frequency-dependent especially at low-frequency around the heartbeat frequency range (0-2 Hz).Dietary melanoidins are late stage Maillard reaction products (MRPs), browning colorants and predominantly high molecular weight (HMW) chemicals. They originate through polycondensation reactions of reducing sugars and proteins or amino acids upon thermal processing. Their presence in several daily food and beverages (i.e. Aminooxoacetic acid sodium salt coffee, beer, honey, bakery products, chocolate, grilled meat) contribute to food sensory characters (i.e. color, aroma, and flavor). Additionally, melanoidins exhibit many biological attributes (i.e. antioxidant, anti-obesity, antibacterial activity and impact on gut microbiota as prebiotics). However, dissecting melanoidins specific biological and functional characteristics in relation to their metabolism and gut interaction with link to their chemical structures has yet to be reported in literature. For a better understanding of melanoidins benefits and flavor properties in processed foods, this review represents a state of the art comprehensive insight of its formation mechanism and chemistry in relation to their functionalities and health effects. Further, a compile of the factors affecting melanoidins production to optimize for the best flavor attributes while minimizing hazardous compounds is presented. This study presents the first analysis of melanoidins gut interaction in context to its different action mechanisms. The abdominal procedure of ventriculoperitoneal or lumboperitoneal shunt is difficult because of a deep and narrow operative view, especially for obese patients. We have developed the 'Hoisting method,' which enables us to make abdominal procedures easy and safe. We report our experience with five cases between April 2020 and March 2021. The placement of the shunt was easy and safe in all patients without any complications. The shunt method is very effective and easy without requiring additional devices.The shunt method is very effective and easy without requiring additional devices. Here we aimed to investigate the predictors of catheter-related bloodstream infections (CRBSI) in patients with acute kidney injury or chronic kidney disease who required renal replacement therapy through a non-tunneled hemodialysis catheter. A total of 111 patients who received non-tunneled hemodialysis catheters were retrospectively evaluated. Patients were divided into two groups; those who developed CRBSI and those who did not. Patient's demographic data, laboratory results at admission, information regarding catheter infections, and culture results were obtained from electronic medical records. The mean age of the patients was 64 ± 16 years, and 51 of them were male. CRBSI occurred in 14 patients (12.6%). Admission serum albumin level (OR 0.119, 95% CI 0.019-0.756,  = 0.024), admission mean platelet volume (OR 2.207, 95% CI 1.188-4.100,  = 0.012) and catheter duration (OR 1.580, 95% CI 1.210-2.064,  = 0.001) were independent predictors for the CRBSI development. ROC curve analysis demonstrated that a catheter duration of 22 days was predictive for presence of CRBSI (78% sensitivity, 76% specificity, AUC 0.825, 95% CI 0.724-0.925,  < 0.001). Prolonged catheter duration, low serum albumin, and high mean platelet volume independently predict the development of CRBSI in patients undergoing hemodialysis for acute kidney injury or chronic kidney disease.Prolonged catheter duration, low serum albumin, and high mean platelet volume independently predict the development of CRBSI in patients undergoing hemodialysis for acute kidney injury or chronic kidney disease.COVID-19 greatly impacted nursing education and required nursing faculty and students to quickly adapt to changes caused by disease mitigation. The purpose of this study was to examine the mediating effects of resilience between the influence of demographics and school-related risk factors and nursing faculty and student quality of life (QoL) during the COVID-19 pandemic. A secondary data analysis was conducted using structural equation modeling to examine the mediating role of resilience on latent variables. Resilience had a positive, direct effect on nursing faculty and student QoL. Having a designated home workspace and being well-prepared for online learning had positive, indirect effects on QoL, mediated through resilience. Assisting children with schoolwork had a negative impact on the psychological and environmental QoL domains. Remarkably, having a caregiver role positively influenced the psychological QoL domain. Supporting and promoting faculty and nursing students' health and well-being is imperative during and after the pandemic. In accordance with the American College of Obstetricians and Gynaecologists recommendations for exercise during pregnancy, this article provides an evidence-based prescription for a group-based prenatal exercise programme. This prescription has been tested in 21 randomized controlled trials. This short report outlines in detail the seven components included in each session (warm-up, aerobic training, resistance training, coordination and balance, pelvic floor training, cool-down, and final discussion). Using the 26-item behaviour change taxonomy proposed by Abraham and Michie, we identified common techniques that are employed in each session to provide a rationale for the high-programme adherence. This session model can be replicated to design prenatal exercise programmes with high adherence and that can be offered by trained exercise professionals.This session model can be replicated to design prenatal exercise programmes with high adherence and that can be offered by trained exercise professionals.
