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 [...]

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 [...]

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 [...]

Gait speed has been correlated to quality of life and has been called the sixth vital sign. The purpose of this study was to understand the factors that comprise fast and comfortable gait speed. 90 older adults provided demographic, cognitive, and functional performance data. Hierarchical linear regression models revealed predictors for comfortable gait speed to be lower-extremity strength ( B = 1.13, β = 0.233, P< .05), comorbid health ( B = −2.95, β = −0.22, P < 0.05), and gender( B = [...]

Plant breeding programs have used conventional breeding methods, such as hybridization, induced mutations, and other methods to manipulate the plant genome within the species' natural genetic boundaries to improve crop varieties. However, repeatedly using conventional breeding methods might lead to the erosion of the gene reservoir, thereby rendering crops vulnerable to environmental stresses and hampering future progress in crop production, food and nutritional security, and socio-economic benefits. Integrating in [...]

Due to the uncertainty and volatility of wind speed, its natural output power also exhibits strong volatility. In order to avoid the negative effects of the excessive fluctuation of the output power of wind turbines in the wind farm and the power grid, it is very important to accurately predict and reasonably plan and control the output power of the wind farm. Model predictive control (MPC) is a type of advanced control method that can deal with a multi-input multi-output nonlinear system. Compared to the tradition [...]

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 [...]

According to the United Nations Environment Programme (UNEP), the construction and operation of buildings accounted for nearly 38% of total global energy-related CO2 emissions in 2019. The construction sector has been striving to use more low-carbon footprint building products to mitigate climate change and enhance environmentally preferable purchasing. Over the last several decades, there has been substantial growth in engineered wood products for the construction industry. To assess these products used in constru [...]

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 [...]

There is a dramatic need for extensive research into the predictors of severe infection with SARS-CoV2 and therapeutic options for infected people. People who suffer from severe illness and higher mortality display a pattern of having specific co-morbidities (diabetes, obesity, hypertension) and are of higher age. Recent research has described methods of viral entry via receptors (ACE2, TMPRSS2) and the hyper-inflammatory state often associated with severe illness (increase in interleukins, increase in TNF-alpha).
