REACTION OF SUNFLOWER GENOTYPES TO THERMAL STRESS CONDITIONS IN THE SANDY SOILS AREA OF SOUTHERN OLTENIA
The researches carried out during 2016-2017 at RDCSPS Dabuleni aimed at the behavior of biological sunflower material, created at NARDI Fundulea, under conditions of thermal water stress from the sandy soils in southern Oltenia. The results obtained at 109 sunflower genotypes underline the favorability of Romania's southern area for sunflower culture. It showed significantly distinct positive correlation between the rate ofĆĀ photosynthesis in the plant, and photosynthetic active radiation (r = 0.282 **) as well as between foliar sweating rate and leaf surface temperature (0.412 **). The production was differentiated according to the genotype and the climatic conditions of the agricultural year, ranging from 2299-5180 kg / ha, with an average of 4307 kg / ha
Kant on Metaphysics as Science
My paper focuses on what and how Kant had accomplished with his intended āre-
form of metaphysicsā through āreasonās entering the secure path of scienceā. In this respect, I
will argue that the influence of (pure) sciences on Kantās programme was a major one, and this
may be best highlighted if one assumes that he developed his mature theory only in the B edi-
tion of his Critique (1787), where the influence of the model of pure a priori sciences turn to be
decisive. This influence, as we already know, is closely related to the āreform of metaphysicsā
by āreasonās entering the secure path of scienceā. My claim is upheld also by the historical ar-
gument that only in the Prolegomena (1783) and in the B edition of the Critique Kant explicitly
conceived the idea of āmetaphysics as scienceā. Therefore, the necessary steps in dealing with
āmetaphysics as scienceā must consider the A Critique, the Prolegomena, and the B Critique in
this precise order. Assuming this order, my approach will involve three parts: in the first I will
investigate the idea of the reform of metaphysics from the A Critique, in the second I will take
into account āreasonās entering the secure path of scienceā (in the Prolegomena and the B Cri-
tique), i.e., philosophy as science (the discipline within the B Critique); finally, I will argue that
understanding Kantās āidea of philosophy as scienceā can best be achieved by focusing on the
role and place that pure sciences have in the transcendental philosophy of the B Critique, where
its structure and content are themed and projected within the methodological frame of the āex-
periment of pure reasonā

Multianalyte Tests for the Early Detection of Cancer: Speedbumps and Barriers
It has become very clear that a single molecular event is inadequate to accurately predict the biology (or pathophysiology) of cancer. Furthermore, using any single molecular event as a biomarker for the early detection of malignancy may not comprehensively identify the majority of individuals with that disease. Therefore, the fact that technologies have arisen that can simultaneously detect several, possibly hundreds, of biomarkers has propelled the field towards the development of multianalyte-based in vitro diagnostic early detection tests for cancer using body fluids such as serum, plasma, sputum, saliva, or urine. These multianalyte tests may be based on the detection of serum autoantibodies to tumor antigens, the presence of cancer-related proteins in serum, or the presence of tumor-specific genomic changes that appear in plasma as free DNA. The implementation of non-invasive diagnostic approaches to detect early stage cancer may provide the physician with evidence of cancer, but the question arises as to how the information will affect the pathway of clinical intervention. The confirmation of a positive result from an in vitro diagnostic cancer test may involve relatively invasive procedures to establish a true cancer diagnosis. If in vitro diagnostic tests are proven to be both specific, i.e. rarely produce false positive results due to unrelated conditions, and sufficiently sensitive, i.e. rarely produce false negative results, then such screening tests offer the potential for early detection and personalized therapeutics using multiple disease-related targets with convenient and non-invasive means. Here we discuss the technical and regulatory barriers inherent in development of clinical multianalyte biomarker assays

RESEARCH ON THE FERTILIZATION OF SWEET POTATOES ACCORDING TO THE NUTRITIONAL SPACE, IN THE SANDY SOIL CONDITIONS FROM ROMANIA
Research conducted during 2015-2017, in the climatic conditions of sandy soils in Romania, highlights the role of fertilization and plant density on the growth and development of sweet potato plants (Ipomoea batatas). The obtained results, show the positive implications of chemical and foliar fertilization on the physiological processes in the plant and on the quantity and quality of the obtained production. The fertilization of the sweet potato culture with N150P80K80, prior to planting and the use of a density of 50000 plants / ha led to a maximum yield of 27907 kg / ha. From the point of view of the quality of the production, the application of two foliar fertilizations with the product Timasol in a concentration of 1%, having N15P15K30 + 13 microelements, determined the increase of the biochemical components from the sweet potato tubers, compared to the only radicular fertilized
BioProfiling.de: analytical web portal for high-throughput cell biology
BioProfiling.de provides a comprehensive analytical toolkit for the interpretation gene/protein lists. As input, BioProfiling.de accepts a gene/protein list. As output, in one submission, the gene list is analyzed by a collection of tools which employs advanced enrichment or network-based statistical frameworks. The gene list is profiled with respect to the most information available regarding gene function, protein interactions, pathway relationships, in silico predicted microRNA to gene associations, as well as, information collected by text mining. BioProfiling.de provides a user friendly dialog-driven web interface for several model organisms and supports most available gene identifiers. The web portal is freely available at http://www.BioProfiling.de/gene_list
Two-dimensional enrichment analysis for mining high-level imaging genetic associations
Enrichment analysis has been widely applied in the genome-wide association studies (GWAS), where gene sets corresponding to biological pathways are examined for significant associations with a phenotype to help increase statistical power and improve biological interpretation. In this work, we expand the scope of enrichment analysis into brain imaging genetics, an emerging field that studies how genetic variation influences brain structure and function measured by neuroimaging quantitative traits (QT). Given the high dimensionality of both imaging and genetic data, we propose to study Imaging Genetic Enrichment Analysis (IGEA), a new enrichment analysis paradigm that jointly considers meaningful gene sets (GS) and brain circuits (BC) and examines whether any given GS-BC pair is enriched in a list of gene-QT findings. Using gene expression data from Allen Human Brain Atlas and imaging genetics data from Alzheimer's Disease Neuroimaging Initiative as test beds, we present an IGEA framework and conduct a proof-of-concept study. This empirical study identifies 12 significant high level two dimensional imaging genetics modules. Many of these modules are relevant to a variety of neurobiological pathways or neurodegenerative diseases, showing the promise of the proposal framework for providing insight into the mechanism of complex diseases
