The great demographic pressure brings tremendous volume of beef demand. The key to solve this problem is the growth and development of Chinese cattle. In order to find molecular markers conducive to the growth and development of Chinese cattle, sequencing was used to determine the position of copy number variations (CNVs), bioinformatics analysis was used to predict the function of ZNF146 gene, real-time fluorescent quantitative polymerase chain reaction (qPCR) was used for CNV genotyping and one-way analysis of variance was used for association analysis. The results showed that there exists CNV in Chr 18: 47225201-47229600 (5.0.1 version) of ZNF146 gene through the early sequencing results in the laboratory and predicted ZNF146 gene was expressed in liver, skeletal muscle and breast cells, and was amplified or overexpressed in pancreatic cancer, which promoted the development of tumour through bioinformatics. Therefore, it is predicted that ZNF146 gene affects the proliferation of muscle cells, and then affects the growth and development of cattle. Furthermore, CNV genotyping of ZNF146 gene was three types (deletion type, normal type and duplication type) by Real-time fluorescent quantitative PCR (qPCR). The association analysis results showed that ZNF146-CNV was significantly correlated with rump length of Qinchuan cattle, hucklebone width of Jiaxian red cattle and heart girth of Yunling cattle. From the above results, ZNF146-CNV had a significant effect on growth traits, which provided an important candidate molecular marker for growth and development of Chinese cattle.
One of the social consequences of the Romanians emigration (generated by he poor socio-economic conditions from Romania) are the children from these families who are left in the country and who can develop different reactions more or less adaptive, depending on the previous psychopatological background of the child and the level of attachment.
This research aims to analyze parent emigration as a precipitant factor in the appearance of anxiety disorders in children coming from these families. Through this study it has been followed the presence of possible associations between the anxiety of the child and its gender, the emigrant parents, the caregiver, the period of absence of the parent.
For the study we analyzed two groups of 43 children each. the two groups correspond in age and location (Maramures County), the dependent variable of the study is represented by the anxiety level. the exclusion criteria were: the presence of the psychiatric diagnosis and the major life events generating stress. to identify the level of anxiety, STAIState Trait Anxiety Inventory (Charles D. Spilberger et al.1970) scale was used. Obtained data were analyzed through statistical program SPSS, version 17.
65.12% from the children with emigrated parents had both parents abroad.
4.65% from the children with the parents abroad had higher levels of anxiety comparative with the children with parents at home.
There is a statistical valid correlation between the level of anxiety in children and the parent emigration.
Spirituality and mental health have always been in a very dynamic relationship. One can wonder if spirituality should be taken out of psychiatry or if psychiatry lost its faith.
The goal of this research is to analyze how anxiety levels are influenced by religious beliefs and practices in children and adolescents.
72 respondents participated in our study. They were pupils in the eighth grade at Scoala Generala Horea, Cluj-Napoca, Romania. the exclusion criteria was any psychiatric disorder diagnosed prior to the research.
We used the questionnaire for anxiety, S.T.A.I. - State Trait Anxiety Inventory (Charles D. Spielberger Ph.D., 1970). the questionnaires about religious beliefs, behaviors and personal motivation: SAI -Spiritual Assessment Inventory (Todd W. Hall, Ph.D&Keith J. Edwards, Ph.D, 1996) and two questions from DUREL - Duke University Religion Index (Koenig HG, Meador K, Parkerson G., 1997). These questionnaires are adapted for a monotheist religion.
To analyze the results, we used SPSS, a Business Intelligence software which includes statistical analysis modules, version 17.
The results identified a valid statistical correlation between anxiety levels and the degree of awareness of God in religious practices and beliefs. (Pearson correlation −0.227, p = 0.05). Depending on the results from SAI questionnaire concerning the level of awareness, we formed 2 groups and we studied the anxiety levels. the analysis of these 2 groups sustained the prior association.
The anxiety levels are lower in children with high degree of spiritual awareness and religious practices and beliefs.
The development activity of a new experimental technique for the study of the fast electron transport in high density matter is reported. This new diagnostic tool enables the X-ray 2D imaging of ultrahigh intensity laser plasmas with simultaneous spectral resolution in a very large energy range to be obtained. Results from recent experiments are discussed, in which the electron propagation in multilayer targets was studied by using the Kα. In particular, results highlighting the role of anisotropic Bremsstrahlung are reported, for the sake of the explanation of the capabilities of the new diagnostics. A discussion of a test experiment conceived to extend the technique to a single-shot operation is finally given.
The influence of the host plant of the cassava mealybug, Phenacoccus manihoti Matile Ferrero on the encyrtid parasitoid Apoanagyrus lopezi De Santis was studied in the laboratory. Four different host plants were used: two cultivars of cassava, Manihot esculenta (Euphorbiaceae), cv. Incoza and cv. MM79; Faux caoutchouc, a hybrid of M. esculenta × M glaziovii; and talinum Talinum triangularae (Portulacaceae), a common weed in cassava fields. Plants were selected for different levels of antibiotic resistance to P. manihoti. Mealybug mortality due to host feeding by the adult parasitoid and the percentage of mealybugs parasitized were significantly lower when mealybugs were reared on the Manihot cultivars and hybrid than when reared on talinum. However, the encapsulation rate was significantly lower in P. manihoti reared on talinum. The highest percentage parasitism and the lowest rate of emergence were recorded on cv. Incoza, the most resistant Manihot cultivar. The sex ratio did not vary significantly with the host plant used. The total developmental time and size of male and female progeny of A. lopezi differed significantly between P. manihoti reared on different host plants. Among Manihot plants, parasitoid size was positively correlated with development time and negatively with plant resistance. Results suggest that the parasitoid, A. lopezi, might perform better if cassava cultivars were selected for their strong antixenosis but low antibiotic characteristics.
We present a series of experimental results, and their interpretation,
connected to various aspects of the hydrodynamics of laser produced
plasmas. Experiments were performed using the Prague PALS iodine laser
working at 0.44 μm wavelength and irradiances up to a few
1014 W/cm2. By adopting large focal spots and
smoothed laser beams, the lateral energy transport and lateral expansion
have been avoided. Therefore we could reach a quasi one-dimensional regime
for which experimental results can be more easily and properly compared to
available analytical models.
