Received: 27 December 2021;  Published: 14 February 2022;  doi: 10.21926/aeer.2201006

Abstract

In September 2020 Hurricane Sally impacted two National Data Buoy Center (www.ndbc.noaa.gov) buoys near its track: 42040 in the deep water and 42012 in the shallow. Using pertinent air-sea interaction formulas from the literature, analyses of these buoy data indicate that, under fully rough airflow and wind sea conditions, U* = a Hs2 /Tp3 + b, here U* is the friction velocity, Hs is the significant wave height, and Tp is the peak wave period. It is found that a = 28 and b = 0.12 for the deep water environment, a = [...]

The Origin of Natural Neurostimulation: A Narrative Review of Noninvasive Brain Stimulation Techniques

Received: 08 September 2024;  Published: 29 November 2024;  doi: 10.21926/obm.neurobiol.2404260

Abstract

This narrative review of the literature on noninvasive brain stimulation techniques observes four neurostimulation domains: light therapy, photobiomodulation, a group of techniques within transcranial electric current and magnetic field stimulations, low-frequency sound stimulations, including vibroacoustic therapy, and rhythmic auditory stimulation. The review aims to determine whether or not different brain stimulation approaches rely upon a similar physicochemical sequence of actions. The study identifies releva [...]

Comparison Between How Narrative Therapy and Buddhist Mantra-Based Meditation Promote Mental Healing

Received: 15 June 2024;  Published: 15 January 2025;  doi: 10.21926/obm.icm.2501004

Abstract

This is a conceptual paper comparing how narrative therapy and Buddhist mantra-based meditation promote mental healing. Narrative therapy promotes mental healing by shifting families’ attention to their subjugated stories of strengths and personal agencies. Whilst Buddhist meditation has been integrated into psychotherapy developed in the West, the application is primarily the focus on breath as a way to help sufferers attain mindfulness. Mantra-based meditation uses the recitation of mantra as the focus inst [...]

Generalized Normal Distribution Optimization Algorithm for Economic Dispatch with Renewable Resources Integration

Received: 18 June 2023;  Published: 28 September 2023;  doi: 10.21926/jept.2303030

Abstract

In an electric power system operation, the main goal of economic dispatch (ED) is to schedule the power outputs of committed generating units efficiently. This involves consideration of relevant system equality and inequality constraints to meet the required power demand at the lowest possible operational cost. This is a challenging optimization problem for power system operators that can be dealt with efficient meta-heuristic algorithms. This article uses a recent meta-heuristic approach named the generalized norm [...]

Effects of Coenzyme Q10 on H2O2-Induced Oxidative Stress of Human Keratinocytes

Received: 05 July 2024;  Published: 06 January 2025;  doi: 10.21926/obm.genet.2501279

Abstract

Keratinocytes are particularly vulnerable to oxidative stress due to their function as the primary natural protective barrier exposed to chemicals, rays, and pollution to stimulate the formation of free radicals in the body. Two factors of interest correlate with cellular senescence under oxidative stress. These include regulating antioxidant synthesis, which maintains free-radical homeostasis through the Nrf2 gene, and the prevention of telomere shortening, which involves the collaboration of human telomerase gene [...]

Gender-Dependent Effects of Endocrine Disrupting Chemicals on Retinoic Acid-Related Orphan Receptor Alpha [RORA] and Aromatase Genes on Human Progenitor Neurons

Received: 28 August 2020;  Published: 07 May 2021;  doi: 10.21926/aeer.2102009

Abstract

Normally we encounter a myriad of chemicals in our daily lives. Endocrine disrupting chemicals [EDCs] are ubiquitous in our environment and upon bodily entry many be stored in adipose tissue and, in pregnant woman, can reach the developing fetal brain, disrupting normal fetal brain development. EDC-induced aberrant levels of sex hormones can alter sexual dimorphism [i.e. degree of feminization or masculinization; sex differences in brain and behavior] and may contribute to the differential susceptibility of males a [...]

Newborn Screening for Mucopolysaccharidosis Type I: Past, Present and Future

Received: 31 March 2023;  Published: 24 July 2023;  doi: 10.21926/obm.genet.2303188

Abstract

Mucopolysaccharidosis type I (MPS I) is a lysosomal storage disorder caused by a deficiency of the lysosomal hydrolase α-L-iduronidase. MPS I is characterized by a broad range of disease manifestations. This includes devastating neurocognitive and bone manifestations and a short life expectancy in severely affected MPS I patients. Neurocognitive manifestations are typically limited in more attenuated MPS I, but patients may still suffer from severe somatic and bone manifestations. Severe MPS I patients are primaril [...]
