Food packaging is used to maintain the safety and quality of food during distribution and storage and to protect them from adverse internal and external conditions, such as water vapor, spoilage due to microorganisms, moisture, light, and dust. In this regard, lots of research studies have been done to increase shelf life, safety, and quality to create suitable physico...

Trehalose is a non-reducing sugar that plays an important role in plant growth and development. To study the role of trehalose on lipid metabolism and gluconeogenesis, Arabidopsis thaliana wild type (WT) and TreF (a line expressing trehalase) were grown on ½ MS medium with or without 100 mM sucrose and or trehalose in light or continuous darkness. In dark, trehalose leads skotomorphoge...

  Background: It has been prover that the prevalence of experiencing job related stress is very high among the dentists. This stress can be the result of factors such as poor lightening of dental office and noise. This stress can cause emotional distress and threaten dentists’ physical health and affect the quality of their life. This study is conducted to determine dentists’ p...

To gain a better understanding of molecular and biochemical events involved in light intensity adaptations of Dunaliella salina, we studied the expression of phytoen synthase (psy) gene; pigments, carbohydrates, proteins and lipids accumulation under two light intensities. The cells were pre-cultured under 50 µmol photon m-2s-1 light intensity and then transferred to two different light intensi...

During recent years, there was growing demand in using microalga valuable products such as β-carotene in health care. β-Carotene has anti-cancer and anti-aging properties for human. In Dunaliella salina cells, β-carotene has a major protecting role for biomolecules, when the production of reactive oxygen species elevated. In the present study, we investigated the influence of the four most effe...
