Photon Recycling for Indoor Energy Harvesting: Optical Optimization of LED-Driven Silicon Photovoltaic Systems

Received: 06 July 2025;  Published: 11 September 2025;  doi: 10.21926/jept.2503013

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 [...]

Papillon-Lefèvre Syndrome and Vitamin D Deficiency: An Intriguing Clinical Observation

Received: 06 April 2025;  Published: 24 June 2025;  doi: 10.21926/obm.genet.2502297

Abstract

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 [...]

An Exploration of the Psycho-Social Factors that Impact the Mental Wellbeing of Unaccompanied Asylum-Seeking Children in UK: A Narrative Review

Received: 23 January 2025;  Published: 17 July 2025;  doi: 10.21926/obm.icm.2503031

Abstract

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 [...]

Modern UNOS Data Reveals Septuagenarians Have Inferior Heart Transplant Survival

Received: 10 November 2024;  Published: 11 June 2025;  doi: 10.21926/obm.transplant.2502252

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 [...]

Design and Simulation of Computational Models of Hybrid Scaffolds Representative of Subchondral Bone and Hyaline Cartilage

Received: 22 August 2024;  Published: 07 March 2025;  doi: 10.21926/obm.transplant.2501240

Abstract

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 [...]

Frank Bahr – A Life Dedicated to Energy Medicine-- In Memory of Prof. Dr. Frank Bahr (1944–2025)

Received: 07 July 2025;  Published: 10 July 2025;  doi: 10.21926/obm.icm.2503030

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.

Pregnancy Risk Factors in Cerebrovascular Disease

Received: 16 May 2024;  Published: 01 April 2025;  doi: 10.21926/obm.neurobiol.2502282

Abstract

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 [...]

A Phase I/II Randomized Trial of Higher Dose mRNA-1273 Boosters in Lung Transplant Recipients

Received: 16 August 2024;  Published: 20 November 2024;  doi: 10.21926/obm.transplant.2404227

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 [...]

A New Technology System to Support Occupational Activity and Mobility in People with Severe-to-Profound Intellectual Disability and Blindness

Received: 14 October 2024;  Published: 12 February 2025;  doi: 10.21926/obm.neurobiol.2501268

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 [...]
