Background: In the last two decades, successful aging (SA) and positive psychology (PP), the two paradigms of health have received great attention. They originate from different approaches, theoretical background, and objectives. Although they share many characteristics, their association remains understudied. This article aims to empirically analyze their possible interrelation. Methods: In this cross-sectional study, 169 healthy, old adults completed several questionnaires to assess the central framework for succ [...]

The shortage of donor lungs for transplantation is a major challenge, resulting in longer waitlist times for patients with a higher risk of waitlist mortality. It is crucial to continue promoting awareness about organ donation through legislation, public campaigns, and health care provider education. Only a small number of cadaveric donors meet the ideal criteria for lung donation, leaving many lungs unused. Donor lung utilization can be improved by carefully considering the extended-criteria donors, actively parti [...]

Gluten-related disorders (GRDs) represent a spectrum of diverse clinical manifestations triggered by the ingestion of gluten in genetically susceptible individuals. The most common and widely recognized diseases within this spectrum are celiac disease and non-celiac gluten sensitivity. The clinical manifestations are intestinal, but extraintestinal manifestations may also appear, such as neurological or psychiatric. This work will specifically review the neurological or psychiatric manifestations that are more freq [...]

Cancer cachexia contributes to 30% of cancer-related deaths. There is currently no treatment or standard of care for cancer cachexia. Many nutritional interventions show promise for the treatment and or prevention of cachexia. Supplementation with omega-3 fatty acids, protein and vitamins either alone or in combination has shown some beneficial effects in the prevention and treatment of cancer cachexia. The mechanisms through which many nutritional interventions work to attenuate cachexia are just beginning to be u [...]

A numerical model describing the ballistic behavior of a commercially used initiator is presented in this article. This model was built on the principle of conservation of mass and energy in the multi-phase framework incorporated with multi-loaded conditions. After obtaining the information about the grain size distribution in each composite, a fixing factor was proposed based on the surface area ratio of the composites. Thus, the solid propellant burning process based on distributed grain size was described, and t [...]

Microbiologically influenced corrosion (MIC) of concrete in sanitary sewer pipe and manholes is the result of dilute sulfuric acid (H2SO4) dissolving the cement matrix. The acid is produced by a complex series of chemical and biochemical reactions. The objectives of this paper are: (1) to review the basic science of the MIC process starting with the various biological processes leading to the production of dilute sulfuric acid; (2) to discuss historical attempts to fortify concrete; (3) to present methods to reduce [...]

Because lithium metal exhibits high specific capacity and low potential, it is the best candidate for fabricating anodes for batteries. Rechargeable batteries fabricated using lithium anode exhibit high capacity and high potential cathode; these can be potentially used to fabricate high energy density batteries (>500 Wh kg-1) that can be used for the development of next-generation electric vehicles. However, the formation and growth of lithium dendrites and the low coulombic efficiency recorded during lithiu [...]

Newborn screening (NBS) for Severe Combined Immunodeficiency (SCID) has been successfully implemented in all 50 United States and Puerto Rico from 2008-2018. This life-saving screening tool has drastically improved overall survival of babies diagnosed with SCID from 74% to 96%. TREC is a stable, circular DNA molecule that is produced during the process of T-cell receptor (TCR) rearrangement and is the target of the quantitative PCR screen on Guthrie cards. Low TRECs are a marker of low naive T cell numbers. This ne [...]

A connection structure using both a screw and friction is advantageous to secure an abutment to an implant. Understanding the biomechanics of the implant-abutment connection is necessary for the long-term clinical survival of a dental implant with decreased complications. The internal conical friction connection structure and micro-threads have shown favorable biological hard tissue response with exceptional structural features. The internal conical connection structure maintains the soft tissue seal and the margin [...]

Continued industrialization, urbanization and ecological destruction have caused significant environmental problems, particularly increased water pollution. Introducing harmful organic and inorganic effluents into watercourses has limited the supply and accessibility of safe and affordable drinking water. There is an urgent need to find green and sustainable abatement solutions for water remediation, many based on nanoparticles. The primary objective of this review is to explore and have a comprehensive discussion [...]
