Nitrogen assimilation and photosynthetic capacity of wheat genotypes under optimal and deficient nitrogen supply

The performance of two varieties of contrasting Bulgarian wheat (Slomer, a former cultivar and enola, a modern half-dwarf) with nitrogen deficiency has been compared by measuring biochemical parameters characterizing absorption and assimilation as well as growth and the photosynthetic activity of young young plants.

The old genotype has made better photosynthetic capacity, higher assimilation, expressed by a high synthesis of amino acids and better overall performance in the limitation. This could be explained by the fact that the selection of old varieties was carried out mainly in low nutrient environments and, as a result, these genotypes have been more appropriate for the growth of low entry conditions. When limiting N provides sugars of modern varieties preferably accumulated, while the former level of amino acids is high. It has been shown that the processes involved in N metabolism were closely linked with photochemical reactions and carbon assimilation even at the early stage of development.

A woman buffalo (Bubalus bubalis) of the Bulgarian Breed Murrah aged 1090 days was observed to give birth to a second newborn (normally developed man) after she had dressed (normal woman) 49 days earlier. This phenomenon is strongly associated with its treatment of melatonin in an induction test of puberty, the last ears implants being placed about 50 days before the supposed date of the first coupling, at which the level of progesterone had increased considerably. . None of the accumulations of the dam has been a witness visually to prove an ovulation on existing gestation, we take the freedom to qualify this phenomenon as superfection, excluding other possible phenomena, namely the embryonic diapause, because it is strongly unlikely to occur in any breeding. Species and differentiated development of twin fetuses as associated with fetal malformation, which has not been observed in this case.

 

Population dynamics in Italian canids between the late Pleistocene and bronze

Dog domestication is still largely unresolved due to shortcomings in time in regional sampling. The old Italian canids are particularly undetened, currently represented by some specimens. In this study, we sampled 27 canids from northern Italy dated the age of the end of Pleistocene and bronze to assess their genetic variability, then add the context of the dynamics of domestication of dogs. They have been targeted with four DNA fragments in the hypervariable region 1 of mitochondrial DNA. In total, 11 samples had a good preservation of DNA and were used for phylogenetic analyzes. 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 in the landscape of the genetic variability of old and modern dog, especially On the old Italian samples published so far.

Our results suggest that there is high genetic variability in the ancient Italian canids, where close relations were obvious between an Italian canid of ~ 24,700 years and ancient Iberian and Bulgarian dogs. These results emphasize that the dynamics of domestication of moving dogs enjoys the analysis of the specimens of the regions of South Europe. Fragile subjects with chronic heart failure (CHF) often demonstrate limited tolerance of effort, shortness of breath and reduced walking capacity resulting from poor quality of life (qol). The objective of this study was to quantify improvements in functional exercise capacity (FEC) and Qol in Bulgarian fragile topics with CHF high-intensity aerobic intervals (HIAIT) / intervention. Ullevaale based on a group, as well as comparing it with moderate intensity. Continuing Education Protocol (Mict).

The relationship between MLSB resistance and virulence genotypes that are common among staphylococcus aureus Bulgaria isolates

The purpose of this study was to investigate the level of resistance to the antibiotic macrolide-lincosamide-streptogramin B (MLSB), the mechanism underlying this resistance and to evaluate their relationship with the virulence gene of 435 clinical insulating Bulgaria aureus staphylococcus aureus staphylococcus. The highest resistance was observed with penicillin (96.09%), followed by resistance to erythromycin and clindamycin (34.02 and 22.76% respectively). From the clinical strain of S. aureus tested, 96.09% contained Blaz genes associated with penicillin resistance and 11.03%, MECA genes responsible for methyylin resistance. The most common is an ERM genotype associated with its existence especially from EMA and EMC genes followed by EMB. The frequency level of these genes, itself or in combination is EMA 41.89%, EMB 27.70%, EMC 43.99%.

The majority of S. aureus resistant Macrolide Bulgaria shows the CMLS phenotype, at 58.78%. This survey found a correlation between virulence profiles with a small number of genes and macrolide resistance among clinical isolates S. Aureus Bulgaria, in contrast to sensitive strains, which have a profile especially with many genes. Sprint that effectively requires large acceleration capabilities. To accelerate, large quantities must be produced and applied effectively. Use of different tools such as SLED and vest can increase the number of styles produced and change the effectiveness of running. We propose the use of increasing excess through Bulgaria Bag (BB) as a means to modify the athlete sprints and increase power and power production.
