Biologically active compounds in algae and their application in plant growth stimulation
2016
In recent years the bioactive substances of natural origin gained more and more interest. Among such substances, the compounds isolated from microalgae and seaweeds, mainly the polyphenols, polysaccharides, plant hormones, pigments and fatty acids, an find an application in many industries, particularly in medicine, pharmaceutics, cosmetics and agriculture. Biostimulants from seaweeds have been used and manufactured for years, giving confirmation of its effectiveness in field trials, enhancing the growth of crops giving better yields. Nowadays, the legislation processes are more difficult and intricate, so it is harder to register new products. Everyone put more attention on the answers for…
Investigation of the resistance of different varieties of buckwheat to infectious diseases after the pre-sowing treatment of seeds and vegetating pla…
2016
In the work it was investigated the influence of sodium humate, biological products "Vermisol", "Vitasym" and "Bioeco-funge-1" on buckwheat lesion of Botrytis bunch rot, Downy mildew, Ascochyta blight, bacteriosis, burn virus and a complex of diseases after pre-sowing treatment of seeds and vegetating plants of Victoria, Roxolana, Kara-Dag, Rubra, Zelenokvitkova-90,Stepova, Elena, Aelita, Lada and Fagopyrum tataricum Gaertn buckwheat varieties. The prospects of these biological products use under agrocenosis conditions to protect the crops of buckwheat from the complex of diseases were shown. The highest effi- ciency identified for the drug "Bioecofunge-1" which , in addition to protecting …
Genetic and environmental effects on body mass index during adolescence: a prospective study among Finnish twins
2009
Objective: To study genetic and environmental factors affecting body mass index (BMI) and BMI phenotypic correlations across adolescence. Design: Prospective, population-based, twin cohort study. Participants and methods: We used twin modeling in 2413 monozygotic and same-sex and opposite-sex dizygotic Finnish twin pairs born in 1983–1987 and assessed using self-report questionnaires at 11–12, 14 and 17 years of age. Results: Heritability of BMI was estimated to be 0.58–0.69 among 11–12- and 14-year-old boys and girls, 0.83 among 17-year-old boys and 0.74 among 17-year-old girls. Common environmental effects shared by siblings were 0.15–0.24 among 11–12- and 14-year-old boys and girls but n…
Concurrent endurance and strength training : neuromuscular, cardiorespiratory and hormonal effects of the exercise order in previously untrained and …
2015
The aim of the present thesis was two-fold. First, to investigate physiological adaptations to concurrent endurance and strength training performed in the same session with different exercise orders (i.e. commencing training with endurance or strength, respectively; E+S vs. S+E) in previously untrained men (n=42) (study 1). Second, to examine physiological adaptations when strength training was always performed immediately after endurance running in the same session (E+S) compared to endurance training alone (E) in recreational endurance runners (n=30) (study 2). In study 1, training consisted of 2 - 3 weekly combined endurance cycling and mixed hypertrophic and maximal strength training se…
Valoración de la regeneración ósea en un modelo animal: Utilización del plasma rico en plaquetas en la curación de los defectos óseos. Estudio prelim…
2007
INTRODUCCIÓN: Los factores de crecimiento y otras moléculas con capacidad osteoinductora pueden considerarse biomateriales que poseen actividad importante en los procesos de reparación y regeneración de los seres vivos. Esta capacidad puede utilizarse para favorecer, asegurar y aumentar lo procesos de reparación del tejido óseo. En esta tesis doctoral se realiza el estudio de la aplicación aislada en un defecto óseo, de un compuesto rico en plaquetas y factores de crecimiento, el plasma rico en plaquetas (PRP).MATERIAL Y MÉTODO: Hemos realizado un estudio experimental prospectivo, comparativo bilateral y controlado, interviniendo quirúrgicamente 30 conejos raza Nueva Zelanda, a los que se p…
The ends of manifolds with bounded geometry and linear growth
2004
We prove that simply connected open manifolds of bounded geometry, linear growth and sublinear filling growth (e.g. finite filling area) are simply connected at infinity.
Breast cancer cell growth/motility is influenced by metal compounds
2019
Triple-negative breast cancer (TNBC) is a highly "aggressive" malignant neoplasm with limited treatment options due to the lack of expression of estrogen and progesterone receptors and HER2/neu. In search of novel molecules displaying anti-TNBC activities, the TNBC cell line MDA-MB231 was exposed to cadmium chloride and/or manganese chloride, and a biological characterization of the effect observed was performed. The data obtained demonstrate a cytotoxic effect exerted by cadmium chloride with drastic changes affecting gene expressions and production of reactive oxygen species. Conversely, manganese chloride was effective in increasing cell number and promoting cell invasive ability. Such e…
Longitudinal Study of Cytokine Expression, Lipid Profile and Neuronal Growth Factors in Human Breast Milk from Term and Preterm Deliveries
2015
Breast milk (BM) is considered as a reference for infant nutrition. The role of bioactive components, such as cytokines, hormones, growth factors (GFs) and fatty acids (FAs) is poorly known, but they might be implicated in immune response development. The aim of this study was to identify the lipid profile and the spectrum of cytokines and neuronal GF in BM samples and analyse the influence of gestational age and lactation time on these components. This study used a longitudinal prospective method for the characterization of cytokines, FAs and GFs global profiles in 120 BM samples from 40 healthy mothers (20 preterm and 20 term) collected as colostrum, transitional and mature milk. The cyto…
The effects of fiscal policies on the economic growth in Romania
2017
This paper intends to examine the results of fiscal policy implementation in Romania, their impact on economic growth and how fiscal policies have influenced the growth of budgetary deficits. Our objective is to highlight and explore efficient fiscal consolidation strategies that can ensure a stable economic growth through sustainable public finances. The methodology consists in analysing the information provided by national and international financial institutions, comparing it to past, proposed and assumed values, and examining the efforts and results. The conclusion we reached was that, in order to restore the sustainability of public finances, the need arises for considerable fiscal con…
A Cross-Sectional Analysis of Growth and Profit Rate Distribution: The Spanish Case
2022
We analyse the time evolution of the empirical cross-sectional distribution of firms’ profit and growth rates. In particular, we analyse the conditional properties of the empirical distributions depending on the size of the firms and the business cycle phase. In order to do so, we employ the Laplace distribution as a benchmark, further considering the Subbotin and Asymmetric Exponential Power (AEP hereafter) distributions, to capture the potential asymmetry and leptokurtosis of the empirical distribution. Our results show that the profit rates of large firms are characterised by an asymmetric Laplace distribution with parameters largely independent of the business cycle phase. Small firms, …
