The Mediator Role of Feelings of Guilt in the Process of Burnout and Psychosomatic Disorders: A Cross-Cultural Study

2021

Burnout was recently declared by WHO as an “occupational phenomenon” in the International Classification of Diseases 11th revision (ICD-11), recognizing burnout as a serious health issue. Earlier studies have shown that feelings of guilt appear to be involved in the burnout process. However, the exact nature of the relationships among burnout, guilt and psychosomatic disorders remains unclear. The purpose of this study was to investigate the mediator role of feelings of guilt in the relationship between burnout and psychosomatic disorders, and perform a cross-cultural validation of the multi-dimensional model by Gil-Monte in two samples of teachers (Portuguese vs. Spanish). The study sample…

Secondhand horror: effects of direct and indirect predator cues on behavior and reproduction of the bank vole

2019

Risk recognition by prey is of paramount importance within the evolutionary arms race between predator and prey. Prey species are able to detect direct predator cues like odors and adjust their behavior appropriately. The question arises whether an indirect predation cue, such as the odor of scared individuals, can be detected by conspecifics and subsequently affects recipient behavior. Parents may also transfer their experience with predators to their offspring. In two experiments, we assessed how direct and indirect predation cues affect bank vole (Myodes glareolus) foraging behavior, reproduction, and pup fitness. Weasel (Mustela nivalis) odor served as the direct cue, whereas the odor o…

Financial Stress and Basis in Energy Markets

2021

We investigate the relationship between energy commodities bases, inventory and financial stress from 1994 to 2018. We find that, from the 1998 Asian crisis the effect of financial stress on energy commodities bases gradually increased and from the 2008 crisis became positive, while the effect of inventory showed a gradual decline over time. The reactions of bases to changes in financial stress is nonlinear, as they are higher in the high financial stress periods. This is more profound in crude oil market than heating oil and natural gas. Moreover, the reactions of bases to the changes in inventory is nonlinear, as the reactions are lower when the inventory level is high confirming the theo…

Recovery of rescuers from a 24-hour shift and its association with physical fitness

2013

The work of rescuers can be physically and psychologically very demanding so it is important for them to have sufficient recovery between work shifts. The purpose of this thesis was to study recovery of rescuers and to see if physical fitness is associated with recovery from work shifts. Heart rate variability (HRV) recordings reflect changes in the autonomic nervous system, and they were used for the analysis of stress and recovery. HRV was recorded for 96 hours, from the beginning of a 24-hour work shift to the beginning of the next shift. Physical fitness assessment included VO2max estimation with a submaximal bicycle ergometer test, and maximal strength testing (isometric bench press an…

Fiziskā un psihoemocionālā slodze farmaceitiem un veselības veicināšanas pasākumi

2022

Farmaceitu darbs ir ļoti smags, gan fiziski, gan emocionāli. Pastāvīgi zvanošs tālrunis, pacientu konsultēšana, monotons darbs ar recepšu un bezrecepšu medikamentiem, smaga fiziskā slodze uz muguru un kājām, ilgās stundas pavadītas pie datora ekrāna ar nepiemērotu apgaismojumu, spēj atstāt uz farmaceitiem un farmācijas sfērā strādājošiem darbiniekiem negatīvas sekas gan mentali, gan fiziski. Aptiekas darbinieku vidū neskaidrība par darba turpināšanu, liela darba slodze, neliels darbinieku skaits un nespēja atjaunināt un uzlabot profesionālo kompetenci ir nozīmīgi stresa faktori, kas ietekmē veselību kopumā. Šī darba mērķis bija analizēt fizisko un psihoemocionālo slodzi farmaceitiem, un izs…

Fizisko aktivitāšu saistība ar uztverto stresu

2021

Pētījuma mērķis bija noskaidrot fizisko aktivitāšu saistību ar uztverto stresu. Pētījumā piedalījās 265 respondenti, no tiem 57 (21,5%) vīrieši un 208 (78,5%) sievietes, vecumā no 16 līdz 74 gadiem (M = 29,66, SD = 12,43). Uztvertā stresa mērīšanai tika izmantota Uztvertā stresa skala (Perceived Stress Scale (PSS), Cohen, Kamarck & Memelstein, 1983, aptauju latviešu valodā adaptējusi Ieva Stokenberga, 2008) un fiziskās aktivitāšu mērīšanai tika izmantota Fiziskās aktivitātes līmeņa aptauja un pašnovērtējums (Judzika, 2018). Pētījuma rezultāti neparādīja statistiski nozīmīgas saistības starp fiziskām aktivitātēm un uztverto stresu.

Viscoelastic properties of acid milk gel as affected by fat nature at low level

2005

International audience; The viscoelastic properties of acid milk gels containing small amounts of different fats were investigated. Skim milk was reconstituted from ultra low-heat skim milk powder and emulsions made with 2% (v/v) sunflower oil, olive oil, groundnut oil, or anhydrous milk fat using a pressure homogenizer. Acidification at 20 °C for 14 h to pH ∼4.6 was achieved by adding glucono-δ-lactone to the emulsion. Stress relaxation testing enabled determination of the firmness and the solid-like properties, i.e., elasticity. Regardless of the physical state of the fat, emulsion gels exhibited higher firmness than fat-free gels, despite the low fat level used. The firmness of the gels …

Bioaccesibility of Cylindrospermopsin from cooked fish muscle after the application of an in vitro digestion model and its bioavailability.

2017

Humans can be exposed to cyanotoxins through the ingestion of contaminated water, food or beverages. In the present work, the bioaccesibility of Cylindrospermopsin (CYN), one of the most relevant cyanotoxins, was evaluated in a pure CYN solution and cooked CYN-contaminated fish muscles (20 μg/mL). An in vitro digestion model including the salivar, gastric, duodenal and colonic phases was performed, being each fraction analyzed by HPLC-MS-MS to evaluate CYN degradation. Moreover, Caco-2/TC7 cells were exposed to the digested duodenal and colonic phases to elucidate the final bioavailability of CYN in an approximation to the real human exposure scenario. The results revealed that CYN bioacces…

EXTRA VIRGIN OLIVE OIL IMPROVES LEARNING AND MEMORY IN SAMP8 MICE

2011

Abstract. Polyphenols are potent antioxidants found in extra virgin olive oil (EVOO); antioxidants have been shown to reverse age- and disease-related learning and memory deficits. We examined the effects of EVOO on learning and memory in SAMP8 mice, an age-related learning/memory impairment model associated with increased amyloid- protein and brain oxidative damage. We administered EVOO, coconut oil, or butter to 11 month old SAMP8 mice for 6 weeks. Mice were tested in T-maze foot shock avoidance and one-trial novel object recognition with a 24 h delay. Mice which received EVOO had improved acquisition in the T-maze and spent more time with the novel object in one-trial novel object recogni…
