“…Erythrocyte ATC was positively correlated with plasma Cu (r = 0.301, p = 0.037); it could be due to the prooxidant effect of this element on the body and the protection of ROS by vitamin E in plasma and erythrocytes [60,61]. Vitamin E protects the body against copper-induced damage due to its antioxidant activity [62], although Hajiani et al [55] suggested that Cu/Zn-SOD activity and expression does not change dramatically in response to vitamin E. Cinar et al [63] showed that Cu intake caused the oxidative stress, and the combination of vitamin C and the addition of vitamin E could alleviate the damaging effects of Cu, as evidenced by the decrease in lipid peroxidation and liver enzymes, however, more research studies in humans are needed.…”

The aim of the present study was to evaluate the basal concentrations of malondialdehyde (MDA) nonenzymatic antioxidants, such as ascorbic acid, α-tocopherol, and retinol in plasma or erythrocytes, and the plasma concentrations of 16 trace minerals in endurance athletes from Extremadura (Spain). In addition, we aimed to assess the possible relationships between some parameters related to cellular oxidative stress with plasma concentrations of some trace minerals. Sixty-two national long-distance men athletes participated in this study. The parameters related to oxidative stress and antioxidant activity were analyzed through high pressure liquid chromatography (HPLC), and trace minerals analysis was performed by inductively coupled plasma mass spectrometry (ICP-MS). We found that plasma MDA was positively correlated with selenium and rubidium. Plasma ascorbic acid was positively correlated with manganese and negatively correlated with cobalt and cadmium. Erythrocyte ascorbic acid was related to arsenic and cesium. Plasma α-tocopherol correlated with copper and manganese negatively and positively with arsenic. Erythrocyte α-tocopherol was positively related to copper, rubidium, and lithium. The findings show that athletes with a high degree of training should monitor their intake and concentrations of α-tocopherol for its fundamental role of neutralizing the excess of reactive oxygen species produced by exercise and the prooxidant effects of several minerals such as arsenic, copper, and lithium.

“…A number of stress factors including environmental and management variables such as climatic condition, type of soil and weaning practices have also been reported to be contributing factors to calf ill-thrift (Reid and Howath, 1980;Scibilia, et al 1987). Stress of trace element deficiencies and hot climatic condition generally increases the production of free radicals , leading to oxidative stress (Elsayed, 2001;Saleh et al 2008) which has a negative impact on the calves live weight, mortality and health. The present study was designed to evaluate some trace element status and total antioxidant profile in ill-thrift calves.…”

The goal of the present study was to evaluate some trace element concentrations and the activity of antioxidant systems in ill-thrift calves. A total number of (52) buffalo-calf was subjected to study. Out of them, (37) buffalo-calves had poor coat, poor general body condition score which constituted the ill-thrift group. The remained animals (15) were clinically healthy and kept as control group. Complete blood picture, trace elements profile, serum calcium, phosphorus & magnesium , blood urea nitrogen (BUN) , creatinine, some liver function parameters and total antioxidants capacity were evaluated. Results showed a significant reduction in the blood serum concentration of copper, cobalt, iron, selenium and zinc associated with normocytic normochromic anemia. Also a significant reduction in the activity of total antioxidants value was evident in ill-thrift calves. While levels of serum calcium, phosphorus and magnesium , blood urea nitrogen, creatinine and liver function parameters showed non-significant changes. In conclusion, a state of sub-optimal growth (ill-thrift) in buffalo-calves was largely attributed to trace element deficiency, in particular copper, cobalt, iron, selenium and zinc deficiency that may cause reduction in the total antioxidant capacity, with a lower ability to reduce oxidative compounds.

“…Through this mechanism, ROS are able to damage numerous cellular molecules, such as proteins, lipids, nucleic acids, amino acids, carbohydrates and vitamins [2]. Physiologically, the free radicals supply the immune system in the defense against bacteria; in case of excessive production that cannot be counteracted by cytoprotective mechanisms, there is an "oxidative stress" that promotes the insurgence of serious pathologies as a result of the degenerative damage of the cellular structures [3][4][5][6].…”

Changes in circadian rhythms of dROMs, Oxy-ads and SHp during reproductive stages were studied in Comisana ewes. Twelve ewes were divided in two equal groups. The experimental group consisted of ewes undergoing gestation and lactation following artificial insemination and the control group consisted of non-pregnant ewes. Blood samples were collected every 3 h over a 24 h period, 20 days before insemination, on days 100 and 140 of pregnancy, on days 10, 30 and 200 post-partum and during the dry period. In the control group, blood samples were collected on the same days and with the same procedures as those used for the experimental group. A significant effect of time on all parameters studied was observed in the experimental group. Daily rhythms of the parameters studied were observed in the control group in all experimental conditions, and in the experimental group during pre-pregnancy and dry periods. We conclude that the reproductive status of sheep affects oxidative stress markers in blood and their circadian rhythms.© Versita Sp. z o.o.
