The objective of this review was to address the stress effects on meat quality considering the main attributes that involve meat *** protein production has been increasing with global demand for meat with meat quality a major concern,especially for more demanding consumers who are looking for quality products to meet their *** quality of the meat is the result of what happened to the animal throughout the production chain,that is,good rearing conditions result in a better meat *** types of stress can be harmful to animals due to inadequate or improper animal handling on farms,inadequate transport conditions,poorly maintained trucks and roads,and conditions that agitate animals can lead to bruising,thermal *** stress in animals occurs when they are in adverse conditions and can significantly compromise meat quality *** an example,stress can significantly affect meat quality parameters as drip loss(DL),meat color,change ultimate pH and cause meat *** the main parameters of evaluation used for meat quality are color,characterized by luminosity(L^*,a^*,b^*),lipid and protein oxidation,pH,water holding capacity(WHC)and *** and processing high-quality meat is a challenge since it is necessary to apply methods that promote comfort in a complete sense,in a way that minimizes inducing significant *** on the results presented it is remarkable that stress alters the meat quality,compromising the main attributes that involve it,like color,pH,WHC,Warner-Bratzler shear force(WBSF),lipid oxidation,among others andis necessary to avoid or reduce stress caused during the production of the animals to ensure a high-quality meat,resulting in greater profitability for the producer.

Li (lithium), a mood stabilizer has anti-inflammatory effect. However, in clinical practice, Li can be administered together with other antidepressants drugs, such as FLX (fluoxetine), IMI (imipramine), NOR (nortriptyline) and ESC (escitalopram). As interaction between Li and these antidepressant drugs on inflammatory modulation has not been investigated yet, we performed an in vitro protocol using a non-human macrophage cell line. Oxidative and inflammatory markers, as well as cell cycle analysis and cytokine gene expressions were compared among treatments. An IR (inflammatory ratio) was calculated based on the following oxidative-inflammatory variables: nitric oxide, superoxide anion, reactive oxygen molecules, cytokines IL-1β, IL-6, TNF-α and IL-10. The in vitro calculated IR data were validated through an in vivo analysis of 154 human subjects with similar IR. Li and control cells presented similar IR values. FLX, NOR and IMI increased slightly IR values indicating some proinflammatory effect, whereas ESC decreased IR values indicating some anti-inflammatory effect. However, cells exposed to Li + ESC triggered a proinflammatory response on macrophages. Thus, IR comparison results suggest that the Li anti-inflammatory effect is not universal and could be influenced by both basal macrophage-inflammatory state and interaction of other psychiatric drugs. These results could be useful to understand some inconsistencies observed in human studies involving Li and other psychiatric drugs.
