Analysing head and trunk motion in the judo osoto-gari technique: relationship to sweeping-leg velocity.
PeerJ

Background: Osoto-gari is a leg throw technique that primarily relies on the hip extension to initiate the sweeping motion of the leg. A high sweep contact velocity is a crucial factor in efficiently executing this technique. While some literature emphasises whole-body coordination in the leg-sweeping action, the roles of trunk and head motion remain unclear.

The widespread accumulation of androgenic steroid endocrine disruptors in water and food has garnered increasing attention due to their significant risks to ecosystems and human health. These steroids, which cannot be completely eliminated, highlight the urgent need for advanced detection technologies. In this study, we present a novel emulsion-induced interface-anisotropic assembly strategy to synthesize bowl-like mesoporous polydopamine (PDA) particles, which exhibit high sensitivity in surface-enhanced Raman scattering (SERS) detection.

Rationale: LGD-4033, a selective androgen receptor modulator (SARM), is recognized for promoting muscle growth and enhancing athletic performance. Its potent anabolic effects have led to its prohibition in both human and animal sports. Although initial in vitro studies have offered insights into its metabolism, an in-depth in vivo analysis is necessary to fully understand its metabolic pathways.

Beta - stimulant, that is, β - adrenergic stimulant, also known as β - agonists, is bioactive catecholamine compounds naturally produced in animals' adrenal medulla glands that induce relaxation in asthmatic airway smooth muscles upon inhalation while also temporarily boosting athletic alertness and alleviating fatigue. However, their potential for dependency poses health risks including unnoticed exacerbation leading to severe illness or fatality prompting their inclusion on WADA's prohibited substances list. Surface - enhanced Raman spectroscopy (SERS) offers a rapid, sensitive, and label - free means for identifying characteristic peaks associated with β - agonist compounds.

In this paper, a novel molecularly imprinted polymer membrane modified glassy carbon electrode for electrochemical sensors (MIP-OH-MWCNTs-GCE) for epinephrine (EP) was successfully prepared by a gel-sol method using an optimized functional monomer oligosilsesquioxane-AlO sol-ITO composite sol (ITO-POSS-AlO). Hydroxylated multi-walled carbon nanotubes (OH-MWCNTs) were introduced during the modification of the electrodes, and the electrochemical behavior of EP on the molecularly imprinted electrochemical sensors was probed by the differential pulse velocity (DPV) method. The experimental conditions were optimized.
