Assessment of AAR and Sulfate Attack on Wadi Gravel Concrete after 4 Years in Service

Received: 18 April 2021;  Published: 26 September 2021;  doi: 10.21926/rpm.2103038

Abstract

Wadi gravel is a local aggregate in Qatar that could contribute to enhanced sustainability by replacing expensive imported gabbro. The material needs to be processed before use to reduce sulfate content to acceptable levels. The paper presents the performance assessment of three full-scale buildings, variously made with 50% and 100% Wadi gravel and conventional gabbro concretes. Site monitoring up to four years in service demonstrated the strength development with age and resistance to the aggressive exposure condi [...]

Epigenetic Regulation by Androgen Receptor in Prostate Cancer

Received: 26 May 2018;  Published: 02 November 2018;  doi: 10.21926/obm.genet.1804047

Abstract

Prostate cancer is the most common cancer among men in the world. Androgen receptor (AR), acting as a nuclear receptor, facilitates ligand-dependent transcriptional activation in the nucleus. Androgen deprivation therapy (ADT) is used for the treatment of advanced prostate cancer because androgen and AR signaling drive prostate tumor growth and anti-apoptotic function. Resistance to ADT in most tumors develops quickly; thus, AR continues to be active in relapsed tumors called castration-resistant prostate cancer (C [...]

Molecular Markers Used to Reveal Genetic Diversity and Phylogenetic Relationships in Crop Plants

Received: 16 June 2024;  Published: 12 December 2024;  doi: 10.21926/obm.genet.2404274

Abstract

Genetic diversity allows plants to adapt to changing environmental conditions to survive and increases their ability to respond to yield, production, pests and diseases. The application of molecular markers developed due to developments in biochemistry, molecular biology, and plant technology has shed light on plant genetics and breeding studies and produced an enormous amount of knowledge. The theoretical knowledge will guide in determining the scope, amount, and distribution of different aspects of genetic divers [...]

Zero-Emission Geothermal Power Generation: Experimental Study on Carbonate Mineralization through CO2-Andesitic Pyroclastic Rock Interaction at Oku-Aizu Geothermal Plant

Received: 27 November 2019;  Published: 12 February 2020;  doi: 10.21926/jept.2001002

Abstract

In order to achieve advancement in zero-emission geothermal power generation for fixing the CO2 in the geothermal fluids to the carbonate minerals after binary power generation and reinjection of the fluid into the reservoir, batch-type experiments and geochemical simulations of CO2-andesitic pyroclastic rock interaction (tuff from Oku-Aizu geothermal area) were performed at 150 °C with and without CO2 gas for 15 days. Despite the low Ca content (0.9% wt.%) in the rock, the Ca2+ concentrations in the solutions [...]

TTF-1-Expressing Supratentorial Embryonal Tumors (PNET): A Clinicopathologic Study of Two Cases and Literature Review of TTF-1-Positive Primary Brain Tumors

Received: 07 October 2018;  Published: 14 November 2018;  doi: 10.21926/obm.neurobiol.1804016

Abstract

Thyroid transcription factor 1 (TTF-1) is a nuclear polypeptide and a tissue-restricted member of the homeobox protein family that, when attached to DNA, plays a crucial role in regulating the expression of select genes during early embryonic development of the thyroid, lung, and brain. As often happens, the initial enthusiasm for the diagnostic value of TTF-1 as a selective immunohistochemical marker of lung and thyroid tumors began to dwindle, due to its detection in tumors arising from other organs. TTF-1-expres [...]

Efficacy of Motor Imagery in the Rehabilitation of Stroke Patients: A Scope Review

Received: 29 May 2024;  Published: 06 August 2024;  doi: 10.21926/obm.neurobiol.2403236

Abstract

This review examines the efficacy of motor imagery (MI) as a supplementary rehabilitation technique for stroke patients. Nine randomized controlled trials (RCTs) were analyzed, highlighting MI's potential to enhance motor recovery, mobility, balance, and psychological well-being. Significant improvements in upper-limb function were observed with combined mental and physical practice, evidenced by notable gains in Fugl-Meyer Assessment (FMA) and Action Research Arm Test (ARAT) scores. MI-based exercise programs impr [...]

Implementation of a Whole-School Mindfulness Curriculum in an Urban Elementary School: Tier 1 through Tier 3

Received: 27 November 2022;  Published: 24 May 2023;  doi: 10.21926/obm.icm.2302022

Abstract

Mindful education (ME) in schools can address student well-being and stressors, as well as improve the overall school environment. Implementing a whole-school mindfulness curriculum can be challenging, especially when serving students in both general education and emotional behavioral disorder (EBD) settings. We investigated the feasibility, implementation, and benefits of a whole-school mindfulness curriculum (MindUP) in an urban elementary school. This study is unique in that it investigated how to implement mind [...]

From Light to Sound: Photoacoustic and Ultrasound Imaging in Fundamental Research of Alzheimer’s Disease

Received: 24 October 2019;  Published: 30 April 2020;  doi: 10.21926/obm.neurobiol.2002056

Abstract

Alzheimer’s disease (AD) causes severe cognitive dysfunction and has long been studied for the underlining physiological and pathological mechanisms. Several biomedical imaging modalities have been applied, including MRI, PET, and high-resolution optical microscopy, for research purposes. However, there is still a strong need for imaging tools that can provide high spatiotemporal resolutions with relatively deep penetration to enhance our understanding of AD pathology and monitor treatment progress in fundamental r [...]

Architecture as Habitat: Enhancing Urban Ecosystem Services Using Building Envelopes

Received: 13 August 2021;  Published: 09 November 2021;  doi: 10.21926/aeer.2104029

Abstract

The practice of reconciliation ecology in urban environments relies heavily on urban green space as the primary source of vegetated habitat in cities. However, most cities lack the quantity, connectivity, and accessibility of green space needed to provide essential ecosystem services for the health, well-being, and resilience of human and non-human species. In reaction to urban densification and the increasing frequency and severity of climate change impacts, this study argues that architecture could strategically [...]

Histone O-GlcNAcylation and Potential Biological Functions

Received: 05 July 2018;  Published: 17 September 2018;  doi: 10.21926/obm.genet.1803036

Abstract

Histone modifications play an important role in the control of DNA-based processes by altering the structure and function of chromatin. O-linked N-acetylglucosamine (O-GlcNAc) modification is a form of post-translational modification of proteins that affects the serine (Ser)/threonine (Thr) residues. This process is controlled by a single pair of enzymes, i.e. O-GlcNAc transferase (OGT) and O-GlcNAcase (OGA). Recent evidence indicates the existence of O-GlcNAc modification of histones, with 16 histone O-GlcNAc site [...]
