Photon Recycling for Indoor Energy Harvesting: Optical Optimization of LED-Driven Silicon Photovoltaic Systemsby
Abstract
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 [...] 662 3762 |
Papillon-Lefèvre Syndrome and Vitamin D Deficiency: An Intriguing Clinical ObservationAbstract
We report the case of a 3-year-old girl from a consanguineous marriage, initially diagnosed with vitamin D deficiency–associated periodontitis following early tooth mobility. Despite supplementation, her condition worsened with the onset of palmoplantar hyperkeratosis. Further investigations revealed the diagnosis of Papillon-Lefèvre Syndrome (PLS), a rare genetic disorder causing severe periodontitis and palmoplantar keratosis. The patient was managed with vitamin D supplementation, dental extractions, and a remov [...] 561 3747 |
An Exploration of the Psycho-Social Factors that Impact the Mental Wellbeing of Unaccompanied Asylum-Seeking Children in UK: A Narrative ReviewAbstract
Unaccompanied asylum-seeking children (UASC) are amongst the most vulnerable populations worldwide, facing significant psycho-social and mental health challenges influenced by pre-migration, migration, and post-migration experiences. This narrative review examines the structural, legal, and practical factors affecting UASC, focusing on their lived experiences within the UK’s asylum system. Key areas explored include trauma caused by forced migration (pre-, during and post-migration), ethical dilemmas surrounding ag [...] 411 3736 |
Modern UNOS Data Reveals Septuagenarians Have Inferior Heart Transplant Survivalby
Abstract
While heart transplantation is increasingly performed in the United States for elderly patients, survival outcomes have primarily been analyzed in single-center studies. The few existing long-term studies have indicated no difference in HTx outcomes between patients ≥70 years and 60-69 years age, but these studies only assessed to 5-years post-transplant and included data from the 1980-90s, introducing significant variance due to poorer outcomes in that era. We analyzed the UNOS database from 1987-2020, stratified [...] 657 3730 |
Book Review: Small Supernumerary Marker Chromosomes. BasicsAbstract

Design and Simulation of Computational Models of Hybrid Scaffolds Representative of Subchondral Bone and Hyaline CartilageAbstract
Tissue engineering offers alternatives when it comes to health problems such as trauma or pathologies. One of them is the scaffolds, which provide a favorable architecture, mechanics, and biocompatibility for the fixation of cells. Therefore, the following research aims to design and simulate scaffolds with mixed geometric structures to create a hybrid architecture for osseointegration while maintaining structural properties similar to subchondral bone and hyaline cartilage. Three scaffolds were designed for this p [...] 572 3706 |
Frank Bahr – A Life Dedicated to Energy Medicine-- In Memory of Prof. Dr. Frank Bahr (1944–2025)Abstract
With the passing of Prof. Dr. Frank Bahr, the field of complementary medicine has lost one of its most influential personalities. As a pioneer of auricular medicine in the German-speaking world, he helped shape the field of integrative medicine over many decades. This tribute by Prof. DDr. Gerhard Litscher honors Bahr's work, his convictions, and the legacy of a visionary whose impact on energy and spiritual medicine endures. 590 3703 |
Pregnancy Risk Factors in Cerebrovascular DiseaseAbstract
Cerebrovascular diseases such as strokes and cerebral hemorrhages are important causes of death in the world, which increase during pregnancy due to physiological conditions. This study investigated risk factors such as diabetes mellitus, hypertension and other factors by searching in databases. After searching, 35 articles were reviewed based on the inclusion criteria. The inclusion criteria included articles from 2014-2024 related to the words "pregnancy" AND "cerebrovascular disease." The obtained results were e [...] 506 3696 |
A Phase I/II Randomized Trial of Higher Dose mRNA-1273 Boosters in Lung Transplant Recipientsby
Abstract
Higher-dose mRNA booster vaccines have not been well studied for transplant recipients. This study evaluated the safety, reactogenicity and immunogenicity of higher dose mRNA-1273 booster vaccines among lung transplant recipients (LTRs). This phase 1/2 open-label randomized clinical trial of higher-dose mRNA-1273 booster vaccination enrolled nineteen adult LTRs into the 50 µg (n = 8) vs. 100 µg (n = 11) groups before enrollment was terminated due to the availability of the bivalent mRNA-1273.222 vaccine [...] 716 3696 |
A New Technology System to Support Occupational Activity and Mobility in People with Severe-to-Profound Intellectual Disability and Blindnessby
Abstract
People with severe-to-profound intellectual disability and blindness tend to be sedentary and detached, given their orientation and mobility problems, often combined with their limited interest in their surroundings. An approach to address this problem may involve the use of technology systems guiding the participants through mobility and occupational activity (object use) with a combination of spatial/orientation cues, basic instructions for the responses required by the activity, and positive stimulation during t [...] 562 3686 |
