Research on the monitoring the attack of Coccomyces hiemalis sin. Blumeria jaapi in some cultivars of cherry

Research on the monitoring of the pathogen Coccomyces hiemalis sin. Blumeria jaapi took place on the territory of the Research Station for Fruit Growing Iasi, within the research polygon. The observations were made on 5 cultivars approved at RSFG Iasi and belong to the category of early ripening cultivars. 'Cetățuia', 'Cătălina', 'Andreias', 'Cociuvas' and 'Mihailis' cultivars were studied, their monitoring began in May, analysing 3 trees of each cultivar, 300 leaves from each tree in three repetitions, observing the frequency and intensity of the pathogen's attack. During the growing season of 2022, 4 treatments with fungicides, insecticides and foliar fertilizers were used for phytosanitary maintenance. Following the observations made, the analysed cultivars recorded a minimum attack degree of 0.825% on the 'Cetățuia' cultivar and the highest of 1.63% for the ‘Mihailis’ cultivar. The low degree of attack was due to the earliness of the cultivars studied

Evaluation of the combined therapeutic effect of methylprednisolone and cerebrolysin in traumatic medullar lesion

Objectives: The pharmacological effects of Methylprednisolone and Cerebrolysin have been extensively debated, but from our knowledge there are no studies to evaluate the association of these two drugs in spinal cord injury (SCI).Methods: Twenty-four Wistar rats underwent traumatic spinal cord injury by using clip-compression model. The animals were divided into four groups: group I received Methylprednisolone (MP); group II was injected with Cerebrolysin (C); group III received Methylprednisolone together with Cerebrolysin (MP+C); in the control group we have performed only decompression. The motor recovery of the animals was evaluated using the Ferguson et al. modification of the BBB scale. After ten days the rats were sacrificed. Results: The study demonstrated that the MP + C group presented the most notable recovery of the motor function, but no statistically significant (p>0,05). The first and the second group also presented better results than the fourth group, but the enhanced recovery of those group relative to control group was not statistically significant (p>0,05) Conclusion: The combination of MP and Cerebrolysin in experimental conditions seems to have promising results, but more experimental and clinical studies are necessary to evaluate the real benefit for SCI patients

VIDEO GAMES CONTRIBUTION TO STUDENTS’ ENTREPRENEURIAL TRAITS AND INTENT

Given the popularity of video games and the influences they may pose on individuals’ psychology and behavior, the present study analyses whether video game playing among university students can be correlated with traits associated with an entrepreneur’s profile, which may, in turn, lead to an entrepreneurial intent. The results of the study reveal that students who do play video games show a higher entrepreneurial intent, this relationship being mediated by several psychological and cognitive characteristics. With regards to the psychological and cognitive factors studied, the results also suggest that a favorable attitude towards playing videogames fosters students’ entrepreneurial potential and has a positive effect on the entrepreneurial intent

MMI1 (YKL056c, TMA19), the yeast orthologue of the translationally controlled tumor protein (TCTP) has apoptotic functions and interacts with both microtubules and mitochondria.

The yeast orthologue of mammalian TCTP is here proposed to be named Mmi1p (microtubule and mitochondria interacting protein). This protein displays about 50% amino acid sequence identity with its most distantly related orthologs in higher organisms and therefore probably belongs to a small class of yeast proteins which have housekeeping but so far incompletely known functions needed for every eukaryotic cell. Previous investigations of the protein in both higher cells and yeast revealed that it is highly expressed during active growth, but transcriptionally down-regulated in several kinds of stress situations including starvation stress. In human cells, TCTP presumably has anti-apoptotic functions as it binds to Bcl-XL in vivo. TCTP of higher cells was also shown to interact with the translational machinery. It has acquired an additional function in the mammalian immune system, as it is identical with the histamine releasing factor. Here, we show that in S. cerevisiae induction of apoptosis by mild oxidative stress, replicative ageing or mutation of cdc48 leads to translocation of Mmi1p from the cytoplasm to the mitochondria. Mmi1p is stably but reversibly attached to the outer surface of the mitochondria and can be removed by digestion with proteinase K. Glutathionylation of Mmi1p, which is also induced by oxidants, is not a prerequisite or signal for translocation as shown by replacing the only cysteine of Mmi1p by serine. Mmi1p probably interacts with yeast microtubules as deletion of the gene confers sensitivity to benomyl. Conversely, the deletion mutant displays resistance to hydrogen peroxide stress and shows a small but significant elongation of the mother cell-specific lifespan. Our results so far indicate that Mmi1p is one of the few proteins establishing a functional link between microtubules and mitochondria which may be needed for correct localization of mitochondria during cell division

Modelling and automation of the process of phosphate ion removal from waste waters

Phosphate removal from waste waters has become an environmental necessity, since these phosphates stimulate the growth of aquatic plants and planktons and contribute to the eutrophication process in general. The physicochemical methods of phosphate ion removal are the most effective and reliable. This paper presents studies on the process of phosphate ion removal from waste waters resulting from the fertiliser industry’s use of the method of co-precipitation with iron salts and with calcium hydroxide as the neutralizing agent. The optimal process conditions were established as those that allow achievement of a maximum degree of separation of the phosphate ions. The precipitate resulting from the co-precipitation process was analysed for chemical composition and establishment of thermal and structural stability, and the aim was also to establish in which form the phosphate ions in the formed precipitate can be found. Based on these considerations, the experimental data obtained in the process of phosphate ion removal from waste waters were analysed mathematically and the equations for the dependence of the degree of phosphate separation and residual concentration versus the main parameters of the process were formulated. In this paper an automated scheme for the phosphate ion removal from waste waters by co-precipitation is presented
