Plasma redox response of Sicilian Opuntia Ficus Indica juice in young physically active women.

2017

It is known amateur female athletes show an altered redox status [1] and the consumption of Opuntia Ficus Indica (OFI) decreases oxidative stress (OS) in healthy humans [2]. Therefore, the aim of this study was to investigate whether the supplementation with Sicilian OFI juice affected plasma redox balance following a maximal effort test in young physically active women
 . This study was randomized, double blind, placebo controlled and crossover design. Eight women (23.25±2.95 years old, weight of 54.13±9.05 kg, height of 157.75±0.66 cm and BMI of 21.69±0.66 kg/m2) were randomly divided into 2 groups and each group was supplied with either 50 ml OFI, diluted to 170 ml with water, or 170 ml …

Tryptophan metabolic pathways and brain serotonergic activity: A comparative review

2019

The essential amino acid L-tryptophan (Trp) is the precursor of the monoaminergic neurotransmitter serotonin (5-hydroxytryptamine, 5-HT). Numerous studies have shown that elevated dietary Trp has a suppressive effect on aggressive behavior and post-stress plasma cortisol concentrations in vertebrates, including teleosts. These effects are believed to be mediated by the brain serotonergic system, even though all mechanisms involved are not well understood. The rate of 5-HT biosynthesis is limited by Trp availability, but only in neurons of the hindbrain raphe area predominantly expressing the isoform TPH2 of the enzyme tryptophan hydroxylase (TPH). In the periphery as well as in brain areas …

Nomierinošo bezrecepšu medikamentu un uztura bagātinātāju lietošana un aprite aptiekā

2020

Mūsdienu dzīvi raksturo cilvēka adaptācijas nepieciešamība pēc strauji mainīgu sociālo un tehnoloģisko nosacījumu ietekmes. Mainīgie dzīves apstākļi nereti ir stresa cēlonis. Stress ir cilvēka reakcija uz jebkādiem notikumiem, kas pārsniedz tā adaptācijas iespējas. Bakalaura darba mērķis bija aplūkot nomierinošo preparātu sastāvdaļas, izpētīt lietošanas paradumus dažādās vecuma grupās, salīdzināt pārdošanas apgrozījumu par 2017.gadu, 2018.gadu un 2019.gadu, noskaidrot kuri preparāti ir vispieprasītākie. Pēc apgrozījuma rezultātiem ir redzams, ka ar katru gadu nomierinošo preparātu apgrozījums pieaug. Populārākais medikaments ar nomierinošo efektu ir Sirds pilieni RFF 90 ml un populārākais u…

Examining the longitudinal relationship between visibility and persistence on stress and technology-assisted supplemental work

2023

This study examines the longitudinal relationship between two affordances of organizational information and communication technologies (ICTs)—that is, visibility and persistence—and individuals’ subjective stress and technology-assisted supplemental work (TASW). We propose that visibility and persistence associated with organizational ICTs are often more aptly construed as probabilities for action, rather than merely possibilities for action. The hypotheses are tested using latent change structural equation modeling drawing on two-wave survey data from 437 employees of a global industrial logistics company headquartered in a Nordic country. The findings highlight that visibility is associat…

HPLC/HRMS and GC/MS for Triacylglycerols Characterization of Tuna Fish Oils Obtained from Green Extraction

2023

Background: Fish oil is one of the most common lipidic substances that is consumed as a dietary supplement. The high omega-3 fatty acid content in fish oil is responsible for its numerous health benefits. Fish species such as mackerel, herring, tuna, and salmon are particularly rich in these lipids, which contain two essential omega-3 fatty acids, known as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Objectives: Due to the scarcity of information in the literature, this study aimed to conduct a qualitative and quantitative characterization of triglycerides (TAGs) in crude tuna fish oil using HPLC/HRMS. Fatty acid (FA) determination was also performed using GC/MS. The tuna fis…
