Indoor environments offer a unique opportunity for photon recycling using LED-based illumination, particularly to address energy limitations of solar photovoltaic (PV) systems during nighttime or in low-light conditions. This study presents an optical and electrical performance evaluation of silicon-based photovoltaic (SPV) panels operating under controlled indoor LED lighting. Despite the low irradiance (~1.4 mW/cm2), significant power output was achieved through engineered panel configurations and optimized light [...]

This paper presents a unifying transcultural perspective on human illness, health and wellbeing by integrating insights from cognitive psychology, existential psychotherapy, Zen philosophy, Traditional Chinese Medicine (TCM), and quantum consciousness theory. Kahneman and Tversky’s work on heuristics and biases highlights cognitive constraints shaping decision-making, while Yalom’s existential therapy explores fundamental struggles with death, freedom, and meaning. Watts’ Zen philosophy critiques the illusion of eg [...]

There is a main difference between theories explaining aging as an adaptive phenomenon that is determined and modulated by genes (i.e., the result of a specific “program”) and theories explaining aging as a non-adaptive phenomenon caused by the accumulation of random degenerative events. In fact, for adaptive theories, a genetically determined and modulated program determining aging is indispensable, while for non-adaptive theories, such a program cannot exist. However, there appears to be strong evidence to suppor [...]

Honor and shame function as moral currencies in many collectivistic cultures, shaping individual behavior, gender roles, and psychosocial well-being. This paper introduces Atimiaphobia—a newly proposed specific phobia defined as the intense and persistent fear of losing honor (particularly for men) or being labeled as shameless (particularly for women). Rooted in patriarchal, collectivist, and honor-based cultures, atimiaphobia manifests through intrusive thoughts, hypervigilance, emotional turmoil, and compu [...]

Antibody-mediated rejection (ABMR) remains a major barrier to long-term graft survival in kidney transplantation. Defined by the presence of donor-specific antibodies (DSAs) and characteristic histological changes, such as C4d deposition in peritubular capillaries, ABMR can present acutely, chronically, or subclinically, often manifesting as graft dysfunction. Recent advances in genomic profiling and diagnostic assays have improved our understanding of its pathophysiology, yet therapeutic strategies remain limited. [...]

Telomeres are repetitive structures at the ends of linear chromosomes. Due to incomplete DNA replication at the end of linear DNA molecules, the so called “end replication problem”, telomeres shorten consecutively during cell division. In addition, telomere sequences are highly susceptible to oxidative stress damaging telomeres and resulting in their dysfunction even in non-dividing cells. Telomere shortening has been identified as one of the underlying causes for replicative senescence that can also contribute to [...]

Liver and lung transplantation remain among the most intricate and resource-intensive arenas in modern medicine, challenged by organ scarcity, immunological complexities, and the persistent threat of rejection. According to recent WHO and UNOS reports, approximately 100,000 patients globally await liver transplants annually, with only 30-40% receiving transplants, resulting in waitlist mortality rates of 15-20%. Similarly, lung transplant demand exceeds supply by a factor of 4:1, with 5-year survival rates remainin [...]

Older adults are a growing population characterized by a high prevalence of multimorbidity and age-related conditions, such as organ and pharmacokinetic dysfunction. Medical digital technologies have emerged through the combined use of wearable, implantable, and insertable medical devices with digital systems. Gerontology aims to help older patients with disabilities utilize these technologies. These technologies are used in high-tech medical centers, particularly among older cardiac patients. Many cardiac societie [...]

The high carbon footprint of cement production and the cost and environmental impact of steel reinforcement make conventional concrete unsustainable for long-term use. Reducing cement consumption and identifying sustainable, cost-effective alternatives to steel are critical for lowering construction’s ecological and economic burden. Bio-based supplementary cementitious materials (SCMs), such as rice husk ash (RHA), and natural plant fibers show promise, but prior studies have mostly tested them separately or with v [...]

Provided that cell-mediated immunity (CMI) is known to be vital in managing CMV infection post-transplant along with improving methods to predict the development of cytomegalovirus (CMV) following transplant, CMV-specific-cell-mediated immunoassays have been developed, commercially and research based, to be used in conjunction with pre-transplant CMV serological testing and prophylaxis to help tailor an individual care plan post-transplant. In this review, we assess the status of CMV CMI assays, and their potential [...]
