The effect of the electric shock on embryonic development and neurophysiological traits in the chick’s embryo

Abstract

The objective of this study was to investigate the impact of stimulating the embryo during the dormancy in the incubation period. 450 eggs (Ross 308) were allocated in four treatments each three replicates. The treatments were as follow: T1 control (without shock), T2 Shocked (40) Millivolts (mV), T3 Shocked (50) (mV), T4 Shocked (75) (mV). A different voltage device was used to shock the egg, after marking the eggs with a line of iron filings to ensure electrical conductivity, eggs were shocked at different times three times a day. The results show a significant increase (p<0.01) in embryonic development for embryo weight, chick body weight, Hatchability, and embryo Index (EI) for T2, T3, and especially T4. A significant increase (p<0.01) in neurophysiological traits of neurons, brain weight, and Brain Index (BI) for T2, T3, and especially T4. In concluding the use of electric shock in the embryonic period will developing of the embryo and neurophysiological traits.

Effect of ethylene gas and Tryptophan amino acid in two oat varieties under soil stress conditions

“…The results were consistent with the findings of (9,10) in the difference in oat varieties in the number of Panicles m -2 . The availability of conditions helped to increase the number of Panicles m -2 when adding amino acid, which is consistent with (11)(12)(13), who pointed to the effect of amino acid in increasing the number of Panicles m -2 for wheat crops.…”

“…In Table 3 we note the effect of ethylene gas on the number of grains in Panicle, this is consistent with (14,16) of the moral effect of different ethylene gas compositions in the number of grains in spike for wheat. (4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17), they explained that there is an increase in grain yield for barley, wheat and oat crop when the concentration of medium ethylene gas but the grain product decreases at high concentration. Moreover, (15) pointed out that the harvest index values in the oat crop differed by varieties and genetic composition.…”

Influence of humic and fulvic acid addition on soil N P K availability and broad bean output (Vicia Faba L.)

“…Usually the components of good yield are directly related to the increase in indicators of good vegetative growth, the addition of humic acid improved the vegetative growth, by the activation of vital processes and the consequent increase in nitrogen absorption and increase in the number and fullness of the pods, which indicates a good metabolism in the leaves and the transfer of these products to the seeds, or, the reason may be that humic acids contain amino acids or proteins. The plant benefits directly from it, and this is reflected in the increase in the weight of the seeds 16 , this result was consistent with the findings of (17)(18)(19)(20).…”

A study comparing the oncogenic microRNA-21-5p and the CA15-3 characteristics as an effective tumor marker in breast cancer patients from Iraq.

“…The present study result regarding novel Iraqi summary studies shows the ROC curve yields low sensitivity of CA153, merely 22.47% 18 . The same line with a new study in 2021 showed that the low value of the sensitivity of CA15-3 serum marker in BC patients was only (59.06% ) 24 .…”

“…Diagnostic accuracy and AUC of both circulation biomarkers. sensitivity and specificity of rel-ative expression of circulating miRNA-21 in the BC patients compared with healthy control group 17,18 . Their agreement with the Iranian study showed higher sensitivity and specificity values for microRNA-21 19 .…”
