The Role of Cognition in Balance Control

Received: 14 September 2023;  Published: 17 February 2024;  doi: 10.21926/obm.neurobiol.2401211

Abstract

Balance is the ability to move and/or preserve a particular position while not falling under external force. Human balance is a complex process of integration and coordination of the sensory, motor, and biomechanical components, which is influenced by intrinsic and exogenous factors. One inherent factor that is hypothesized to have an impact on balance is cognition. However, studies about cognition's role in balance control are still limited, and study literature is needed to gain a better understanding. Cognition [...]

Enhancement of Fischer-Tropsch Synthesis by Periodical Draining of the Wax-Filled Pores of a Cobalt Catalyst by Hydrogenolysis

Received: 27 September 2022;  Published: 03 January 2023;  doi: 10.21926/cr.2301001

Abstract

Fischer-Tropsch reactors operated in a steady state suffer from a low pore effectiveness factor and a high methane selectivity caused by internal mass transfer limitations due to the accumulation of long-chain hydrocarbons inside the catalyst pores. Therefore, an alternating process switching between Fischer-Tropsch synthesis (FTS) and drainage of the pores by hydrogenolysis is proposed. The periodical cracking of the accumulated waxes within the (partially) filled pores, realized by a switch from syngas (H2, CO) t [...]

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 [...]

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 [...]
