The yield of two contrasting Bulgarian wheat varieties (Slomer, an ancient cultivar and enola, a modern dwarf medium) with nitrogen deficiency has been compared by measuring the biochemical parameters that characterize the absorption and assimilation, as well as the growth and photosynthetic activity of young plants.
The old genotype has presented better photosynthetic capacity, greater assimilation, expressed by a high synthesis of amino acids and a better general performance in limitation. This could be explained by the fact that the selection of ancient varieties was mainly carried out in low-nutrient environments and, as a result, these genotypes have been more appropriate for the growth of low-entry conditions. By limiting N, preferably accumulated sugars of modern varieties are obtained, while the previous level of amino acids is high. The processes involved in N metabolism have been shown to be closely related to photochemical reactions and carbon assimilation even in the early stages of development.
It was observed that a 1090-day-old female buffalo (Bubalus bubalis) of the Bulgarian Murrah breed gave birth to a second newborn (normally developing male) after dressing (normal female) 49 days earlier. This phenomenon is strongly associated with his treatment of melatonin in a puberty induction test, with the last ear implants being placed about 50 days before the supposed date of the first coupling, in which the progesterone level had increased considerably. . None of the accumulations of the mother has been a visual witness demonstrating ovulation in the existing gestation, we take the liberty of qualifying this phenomenon as superfection, excluding other possible phenomena, namely embryonic diapause, because it is very unlikely to occur anytime. breeding. Species and differentiated development of twin fetuses associated with fetal malformation, which has not been observed in this case.
Population dynamics in Italian canids between the late Pleistocene and bronze
The domestication of dogs is still largely unresolved due to lack of time in regional sampling. The old Italian canids are particularly naked, currently represented by some specimens. In this study, we sampled 27 canids from northern Italy dated late Pleistocene and Bronze to assess their genetic variability, then added the context of dog domestication dynamics. They have targeted four DNA fragments in hypervariable region 1 of mitochondrial DNA. In total, 11 samples had good DNA conservation and were used for phylogenetic analysis. Dog samples have been attributed to dog Hapogroups A, C, and D, and a larger Pleistocene wolf was defined in Wolf Haplogroup 2. We present our data on the old and modern dog genetic variability landscape, especially in the old Italian samples published so far.
Our results suggest that there is high genetic variability in ancient Italian canids, where close relationships were obvious between a ~ 24,700-year-old Italian canid and ancient Iberian and Bulgarian dogs. These results emphasize that the dynamics of domestication of dogs in movement enjoy the analysis of the specimens from the southern regions of Europe. Frail subjects with chronic heart failure (CHF) often show limited exercise tolerance, shortness of breath, and reduced ability to walk as a result of poor quality of life (qol). The aim of this study was to quantify improvements in functional exercise capacity (FEC) and Qol in frail Bulgarian subjects with ICC high intensity aerobic intervals (HIAIT) / intervention. Ullevaale based on a group, in addition to comparing it with moderate intensity. Continuing education protocol (Mict).
