A low-energy laser joining technique suggests a high potential to create various large diameter Nitinol endovascular devices that contain complex geometries. The primary purpose of the study is to investigate the effects of laser joining process parameters with regard to the mechanical and biocompatible performance of Nitinol stents. Both the chemical composition and the microstructure of the laser-welded joints were evaluated using scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDS). In vitro study results on cytotoxicity demonstrated that the joining condition of 8 Hz frequency and 1 kW laser power showed the highest degree of endothelial cell viability after thermal annealing in 500°C for 30 min. Also, in vitro study results showed the highest oxygen content at 0.9 kW laser power, 8 Hz frequency, and 0.3 mm spot size after the thermal annealing. Mechanical performance test results showed that the optimal condition for the highest disconnecting force was found at 1 Hz frequency and 1 kW power with 0.6 mm spot size. Two new endovascular devices have been fabricated using the optimized laser joining parameters, which have demonstrated successful device delivery and retrieval, as well as acute biocompatibility.Hydroxyapatite (HAp) and octacalcium phosphate (OCP) layers were formed on Mg- 4mass% Y- 3mass% rare earth (WE43) alloy by a chemical solution deposition method at various pH values of pH 5.5, 6.2, 7.5, and 8.6. Adhesion strength of HAp and OCP layers was evaluated before and after immersing in a medium for 14 days by a pull-off test. The corrosion resistance of these coatings was measured by polarization tests performed in a simulated body fluid (SBF). XRD analysis demonstrated that HAp coating layers were formed at pH 7.5 and 8.6, while OCP coating layers were formed at pH 5.5 and 6.2. Adhesion test results showed that the as-coated pH7.5-HAp layer had the highest adhesion strength of 8.6 MPa, which was attributed to the very dense structure of the coating layer. The as-coated pH8.6-HAp layer showed the adhesion strength of 6.5 MPa. The adhesion strength of the as-coated pH5.5- and pH6.2-OCP layers was 3.9 and 7.1 MPa, respectively, that was governed by the thick and fragile property of the layers. After immersing in the medium for 14 days, the adhesion strength of pH7.5- and pH8.6-specimens decreased to 5.8 and 5.6 MPa, respectively. The pitting corrosion and formation of Mg(OH)2 under the HAp layers were responsible for the decrease of adhesion strength. The polarization tests in SBF at 37 °C showed that the corrosion current density decreased with the HAp and OCP coatings, indicating the improvement of the corrosion resistance of WE43 alloy. The HAp coatings improved the corrosion resistance more efficiently than the OCP coatings.Very old parents and their "old" children are a growing group in industrialized countries worldwide. However, virtually nothing is known about the nature and implications of this relationship constellation. To fill this gap, this study explored the challenges and rewards of the very old parent-child relationship. In-depth interviews were conducted with 114 parent-child dyads (parent age ≥90; child age ≥65). While both challenges and rewards were present, the balance of challenges and rewards was notably less favorable for children with more challenges experienced overall. Challenges reported by children were often characterized by references to children's own advanced age and health problems, and the prolonged caregiving involvement due to their parents' longevity. Health care professionals, policymakers, and families should be made aware of this increasingly common phenomenon, and specific services and policies will be needed to adequately support very old adults and their families.This paper discussed the influence of disability and the degree of disability on the intergenerational needs of the elderly in terms of time and economy. The data is from the CLHLS in 2018. And the study discussed from 3 dimensions nursing time, economic support, and medical cost support provided by children. The results showed that disability had a significant impact on the care time and medical expenses provided by adult children (care time β = 45.631, P  less then  .001; medical expenses β = 2017.664, P  less then  .01). Compared with the elderly with low degree of disability, the economic intergenerational care needs of the elderly with severe disability increased significantly (β = 2108.078, P  less then  .01). The results of sub sample regression show that the intergenerational care needs of the elderly in China are restricted by objective factors and have not been met. These findings revealed the current situation of intergenerational support for the disabled in China, and emphasized that the government should establish and improve the social formal care, gradually reduce the burden of care for children with disabled elderly families, and improve the quality of life of the disabled elderly.Objective To examine whether the trajectory of facets of loneliness-emotional and social-varied by cognitive impairment status in older adulthood. Methods Data came from the Health and Retirement Study 2008-2018 waves (N = 15,352).  https://www.selleckchem.com/products/Zileuton.html  Cognitive impairment was assessed using standard cutoffs for cognitive impairment no dementia (CIND) and dementia. The 11-item UCLA loneliness scale was used to measure emotional and social loneliness. Results Using multilevel modeling, we found that CIND and dementia status were associated with higher overall, emotional, and social loneliness, controlling for physical health, social contact, and depressive symptoms. The trajectory of loneliness did not vary by cognitive status. There were modest variations by sociodemographic factors. Discussion Persons with CIND and dementia experience heightened emotional and social loneliness, but cognitive impairment does not contribute to the worsening of loneliness. Older adults' social integration may be maintained early in cognitive impairment.
