ss.Rapeseed provides multi-products as human food and animal feed especially the oil and meal. Rapeseed oil and meal after extraction are nutritious and have been used in animal feeding. This study aimed at studying the effect of rapeseed pod meal as the replacement of concentrate (RPM) on in vitro gas and fermentation characteristics. Dietary treatments were imposed in a 2 × 6 factorial arrangement according to a completely randomized design (CRD). The first factor was two ratios of roughage to concentrate (RC at 6040, and 4060) and the second factor was six levels of RPM at 0, 20, 40, 60, 80, and 100% of dietary substrate. The results revealed that the RC ratio and RPM increased kinetics of gas production, in vitro degradability and improved rumen fermentation (P 0.05). Interestingly, both factors have greatly impacted on TVFA, C3 (P less then 0.01) and tended to reduce methane production as level of RPM replacement increased. In conclusion, RPM improved rumen fermentation and increased in vitro DM degradability, hence is potential for replacement of concentrate and effectively used for ruminant feeding.Restoration programs require long-term monitoring and assessment of vegetation growth and productivity. Remote sensing technology is considered to be one of the most powerful technologies for assessing vegetation. However, several limitations have been observed with regard to the use of satellite imagery, especially in drylands, due to the special structure of desert plants. Therefore, this study was conducted in Kuwait's Al Abdali protected area, which is dominated by a Rhanterium epapposum community. This work aimed to determine whether Unmanned Aerial Vehicle (UAV) multispectral imagery could eliminate the challenges associated with satellite imagery by examining the vegetation indices and classification methods for very high multispectral resolution imagery using UAVs. The results showed that the transformed difference vegetation index (TDVI) performed better with arid shrubs and grasses than did the normalized difference vegetation index (NDVI). It was found that the NDVI underestimated the vegetation coverage, especially in locations with high vegetation coverage. It was also found that Support Vector Machine (SVM) and Maximum Likelihood (ML) classifiers demonstrated a higher accuracy, with a significant overall accuracy of 93% and a kappa coefficient of 0.89. Therefore, we concluded that SVM and ML are the best classifiers for assessing desert vegetation and the use of UAVs with multispectral sensors can eliminate some of the major limitations associated with satellite imagery, particularly when dealing with tiny plants such as native desert vegetation. We also believe that these methods are suitable for the purpose of assessing vegetation coverage to support revegetation and restoration programs.Tissue homeostasis of an individual is a finely orchestrated phenomenon that ensures integrity and steady state in health. Emerging evidence indicates that the environment, especially ambient air pollution, has a lasting impact on this equilibrium (Beelen et al., Lancet 383785-795, 2014). Environmental pollution consists of diverse entities, namely, particulate matter (PM 2.5, PM 10), ozone, and UV rays, among others (Heroux et al., Int J Public Health 60619-627, 2015). Understandably, skin epidermis is the first and the most exposed tissue to such a wide range of substances and bears the assault. Previous studies have established that exposure to atmospheric pollution aggravates several skin disorders as, for instance, eczema, acne, lentigines or macules, and wrinkles (Araviiskaia et al., J Eur Acad Dermatol Venereol 331496-1505, 2019). While pollutants can interact with skin surface, contamination of deep skin by particulate matter (either ultrafine particles or by some polycyclic aromatic hydrocarbon (PAH)on exposure.Vanadium is an important ultra-trace element nowadays attracting attention with particular emphasis on medical application. But the therapeutic application of vanadium-based drugs is still questionable and restricted due to some toxic side effects. It was found that unique redox properties of vanadium in nanoform provided antioxidant activity and prevented oxidative disturbance in cells in vitro. Though, on the organism level, ambiguous effects of vanadium-based nanoparticles were observed. In this study, the age-related features of prooxidant/antioxidant balance in blood serum and liver mitochondrial and postmitochondrial fractions of 3 and 18-month-old Wistar male rats treated with orthovanadate nanoparticles (GdVO4/Eu3+, 8 × 25 nm) within 2 months have been investigated. Prooxidant potential-related indexes were the content of lipid hydroperoxides as well as aconitase activity. Activity of glutathione peroxidase, glutathione-S-transferase, glutaredoxin, glutathione reductase, glucose-6-phosphate dehydrogenase, and NADPH-dependent isocitrate dehydrogenase designated the tissue antioxidant potential. find more Based on the obtained values, the integral index of the prooxidant/antioxidant balance-the reliability coefficient (Kr) has been calculated. The data show that due to activation some chain links of GSH-dependent antioxidant system, GdVO4/Eu3+ nanoparticles increase the reliability of the prooxidant-antioxidant balance in tissues and especially in the liver mitochondria of old animals (Kr in mitochondria of young rats was 2.94, and in mitochondria of old ones-9.83 conventional units). Detected in vitro glutathione peroxidase-like activity of the GdVO4/Eu3+ nanoparticles is supposed to be among factors increasing the reliability of the system. So, for the first time, the beneficial effect of the long-term orthovanadate nanoparticle consumption in old males has been discovered.In present study the effect of iron (Fe) and manganese (Mn) contamination was assessed by modeling a freshwater food web of water, zooplankton (Daphnia pulex), and zebrafish (Danio rerio) under laboratory conditions. Metals were added to the rearing media of D. pulex, and enriched zooplankton was fed to zebrafish in a feeding trial. The elemental analysis of rearing water, zooplankton, and fish revealed significant difference in the treatments compared to the control. In D. pulex the Mn level increased almost in parallel with the dose of supplementation, as well as the Fe level differed statistically. A negative influence of the supplementation on the fish growth was observed specific growth rate (SGR%) and weight gain (WG) decreased in Fe and Mn containing treatments. The redundancy analysis (RDA) of concentration data showed strong correlation between the rearing water and D. pulex, as well as the prey organism of Fe- and Mn-enriched D. pulex and the predator organism of D. rerio. The bioconcentration factors (BCF) calculated for water to zooplankton further proved the relationship between the Fe and Mn dosage applied in the treatments and measured in D.
