CHEMOPREVENTION OF HUMAN PROSTATE CANCER BY ORAL ADMINISTRATION OF GREEN TEA CATECHINS: A TRANSLATIONAL RESEARCH STORY
Authors: Bettuzzi S , Rizzi F
Published: December 2021

Clinical progression of Prostate Cancer (CaP) is variable: some tumours are indolent, others

rapidly progress. Because, diagnosis is usually in elderly men, CaP is an ideal target for

chemoprevention. We showed that Green Tea Catechins (GTC) possess anti-tumour activity,

suggesting that it might be beneficial in the early stages of cell transformation. But an experimental

confirmation in a real clinical setting was needed. High-Grade Prostatic Intraepithelial Neoplasia

(HGPIN) is a pre-invasive stage of CaP for which no treatment options are available until CaP is

diagnosed.
Centrifugal Disc Spreading Quality as a Function of Feeding Position: Simulations and Experiments
Authors: GINDERT-KELE Ágnes , ANCZA Erzsébet , HAGYMÁSI Zoltán
Published: December 2021

A combination of an improved analytical model for the description of particle motion on the spinning disc and hodographic ballistics in the air was described earlier. The unified model (Gindert-Kele, 2006) is considered nearly exact for single particles leaving a conical disc with pitched straight vanes. ”In-silico” spreading calculations with experimentally characterized particle clusters are sensitive to both spreader and fertilizer properties. However, parameters like loading area and air-drag coefficients may need empirical corrections. In this work experimental and simulated spreading patterns are compared demonstrating the importance of the angle selection for fertilizer feeding.

Published: December 2021

Distributing different types of fertilizer more accurately and evenly necessary in experimental plots. In probe parcels the more and more precise labour quality demands require mechanization of experiments. A solution is offered to mechanization of distributing fertilizer on probe parcels. A new plot fertilizer distributor was designed and built. I outline here the principle of working of the plot fertilizer. The unevenness of spreading of each type is significantly influenced by the tilt of the cone-belt dispenser from vertical position. A test-bench was collected to measure the aberrations. The measurement proves that only a few degree deviation results in significant change in the unevenness of dispensing.

The Low Productive Soils from Dolj District and Their Main Features
Authors: POPESCU Cristina , VASILE D. , GRECU Florina
Published: December 2021

Due to the heterogenous natural conditions on the Dolj District there were formed an array of soils from the sandy ones to the luvic and stagnogleic ones. The sandy soils that were formed under the influence of Danube River occupy large surfaces on the south western part of the Dolj District and have a high content of basic elements and have a somehow higher fertility than the ones formed on the jiu valley. Generally, the sandy soils from Dolj District have a low fertility status determined by the higher thick material content, higher water permeability and reduced mineral elements content.

The salty soils are present within the Jiu lowland and Danube lowland as discontinuous surfaces where the watertable is shallow. In this zones, along with solonetz and solonceak are encountered on smaller surfaces alluvial soils as salty ones that are low to average salinisated.

The luvosoils occupies the plateau zone of the dolj District, within the low zones where the water logs a longer period during the year determining eluviation phenomena as well as stagnogleisation of the shallow soil profile and helps creating a not quite favorable environment for plant growing.

The reddish preluvosoils and stagnogleisated ones are encountered especially on the northern zone of the district on the plateau that have no drainage where the water logging determines eluviation processes and stagnogleisation, especially on the upper soil profile.

Generally, within the northern part of the district the soils from the slopes have different erosion degrees that determine the decreasing of their fertility.

In Apuseni Mountains, the species Arnica montana L. still has a high frequency and, from here, annually, it is harvested considerable quantities of inflorescences. This way of use it is not sustainable and, from this reason, a sustainable exploitation system of the species it is entailed in the benefit of the phyto – diversity and the local population’s welfare. This system is very complex and implies activities regarding research, training for the local population, commerce, marketing, certification etc. The existence of the species Arnica montana in the grasslands of Gârda de Sus commune is the consequence of a traditional management practiced for a long period of time. The most important attendance work is fertilization, which is only organic performed, and the grasslands are exploited in a mixed way or only through grazing. On these grasslands, along arnica, other key species also appear - in number of 40. On the meadows in Gârda de Sus commune it has been estimated over a three year period an average quantity of 15,8 t of fresh material and it is recommended to be harvested maximum 50% of the existing quantity. The drying of arnica inflorescences in Ghetari hamlet, Gârda de Sus commune and training of the locals are the major premises for obtaining a material of superior quality and, in this way, value it is being added to the commodity at local level. The sustainable exploitation of the arnica species it is being performed by a non-profit association and a LTD society, the first being responsible for the species conservation, and the second one for its exploitation. The arnica material’s certification is a form of value adding to the finite product.

Researches Concerning Decreasing the Forces and the Energy Needed for Tilling the Soil Using Electro-Osmosys Effect
Authors: VLĂDUŢ Valentin , GĂGEANU Paul , BIRIŞ Sorin , BUNGESCU Sorin , POPA Lucreţia
Published: December 2021

Electro-osmosys principle consists of the application of a direct current voltage to an anode-cathode system introduced into soil. The effect of this system consists of the mobilization of water particles from soil and their transport, in a very short period of time, from the anode to cathode. For the tilling machinery the anode may be a disc-knife and the cathode may be the working part (trash board, coulter knife, furrowers, etc). The soil water transported from the anode to cathode, on the tool-soil contact surface, in consequence, will produce a lubrication of an active surface and through this a great decreasing of the friction forces and implicit of the energy needed for displacing the tool through the soil. The energy needed for tilling the soil represents a great part of a total energy consumed for plants crop. When the soil is tilled by pulling or pushing of the tools for farming, a great part of the tilling energy is consumed for defeating the friction forces from the tool-soil contact surfaces. The active surface of the tilling tool may be properly chosen in order to minimize the frictions, respective the mechanic energies needed for tilling.

Published: December 2021

Cultivated potato is susceptible to many pests and pathogens, none of which is more of a threat to potato agriculture than the late blight disease, caused by the oomycete Phytophthora infestans (Mont.) de Bary. Resistant R genes from the wild species of Solanum demissum have been used by breeders to generate late-blight-resistant cultivars. In our research we tried to clone polymorphic bands that could be considered markers for resistant genes. We used 8 resistant potato varieties and one sensible form. After amplification of potato DNA with decamer primers, several polymorphic RAPD sequences were recuperated from the agarose gel, and cloned into E. coli bacteria using two cloning kits. The majority of cloned sequences had approximately the same size with the original recuperated sequence.

Authors: BURJA Camelia , BURJA Vasile
Published: December 2021

Romanian agriculture has a high productive potential owned to the existent agricultural area and to the employed population. The sustainable development of agriculture implies protecting the environment, improving quality of life in the rural area, manufacturing agricultural products based on green principles, but also practicing an efficient and competitive agriculture, based on high economic efficiency. Improving performance and competitiveness targets the efficient use of production factors in accordance with the principles of sustainable development.

Data Envelopment Analysis (DEA) represents an opportunity to assess the performance of socio-economic systems, necessary to justify decisions to allot resources and to rationally establish the objectives in this sector. This method is used by the paper to show the current sustainable development stage of Romanian agriculture compared to the average level recorded by EU agriculture, which represents a goal for Romania for a medium-term time horizon. DEA confirms the information originated from the analysis of statistical indicators regarding the considerable gap between the performances of Romanian agriculture and the ones of the EU concerning the efficient use of land and labour force.

The results of the analysis may serve to justify decisions regarding organizational, technical and economic changes that must be done through the agricultural policy of Romania to increase efficiency and competitiveness in this important sector of the national economy.

Authors: HAS Voichita , GULEA Alin , HAS Ioan , COPANDEAN Ana
Published: December 2021

The objective of this research was to determine whether phenotypic and genetic diversity could be identified for maize grain quality traits (percentage of starch, protein, oil, fiber and ash) and agronomic traits. 59 maize synthetic populations which differed in earliness and for geographic origins were evaluated in the field at the Agricultural Research Station Turda - Romania, for their per se value. Each synthetic population was tested only one year and was characterized for their ear characteristics and grain quality attributes. The grain oil and ash content showed high variability among genotypes.

The experiment was conducted over 2 years (2006-2007) and 2 locations (Turda and Targu-Mures). Analysis of variance showed significant differences among the genotypes for all traits studied. General combining ability (GCA) effects were more important for grain content than specific combining ability (SCA). The occurrence of low interactions between synthetic populations and testers for all characters suggested the occurrence of high statistical additive effects expressed whatever the system of population evaluation. These results support breeding effort towards the genetic improvement of grain quality traits in “Turda” maize germplasm.
Short Chain Food Supply in Flanders (Belgium): Direct Sales of Farm Made Products
Authors: HUYGENS Didier , LIPS Dirk , AERTS Stef
Published: December 2021

During the last decennia, the distance between the producer and the consumer has increased strongly. This enlarged distance manifests in different areas. Firstly, the distance has become larger geographically. Food products are transported around the world and have become common goods. Secondly, the producer and the consumer are driven apart on a social level. Many consumers have never visited a farm and have no idea how their food is produced. Thirdly, the food industry, distribution and the entire agribusiness complex have settled in between producer and consumer, thus enlarging the economical distance.

This system is being criticised from many points of view and opportunities are brought forward that strive towards a more durable process on an ecological level (food kilometres, food transport); an economical level (fair price for both the producer and the consumer, regional economy) and a social level (local contacts, cooperation). A variety of initiatives, both supported by the government and unsupported, are started. It seems that especially in the peri-urban area, being close to both producer and consumer, opportunities exist for short chain initiatives.
Effect of Organic Fertilization on Potato Production in the Mountain Area
Authors: MĂRGHITAŞ Marilena , RUSU Mihai , TOADER Constantin , MIHAI Mihaela
Published: December 2021

In our country, potato is a highly important national crop, as a basic food element (almost the population’s second bread), while for the Apuseni Mountains area, potato holds the highest percentage and at the same time represents an essential food for locals and their animals, as a paramount food support of the population in the area.

Its specific renders this crop as a highly demanding species of plant in terms ecologic conditions, humidity and temperature, as well as nutritive elements, as it forms an abundant vegetative mass and a high tuber quantity for the surface unit. It is a highly consuming nitrogen, potassium , magnesium and calcium plant, as well as with respect to macroelements. Once the potato is harvested, the export of mineral elements from the soil is high, thus determining the rapid soil depletion and demanding for a suitable fertilization of potato crop, adequate to the household system specific to the mountain area.

Numerous researches conducted in the area under study reveal the fact that, from a pedoclimatic point of view, there are good and very good conditions for potato crop, considering the climatic abnormalities in the last period. But the severity of the climatic impact varies from one region to another and exerts a serious effect on agriculture. In this highly important sector, climate changes would influence crop harvest, animal breeding and location of production. The increased probability and severity of weather events will considerably increase the risk of crop calamities. The climate change will exert an influence on the soil, by decreasing the organic matter content- a major contributor to soil fertility. In this context, considering the basic occupation of locals in the area, especially animal breeding, alarge quantity of organic fertilizers is used and by meas of their rational employment, they represent the main fertilizatio source of crops in the area, recovery and maintenance of soil fertility.

Alongside being the basic food product of population in the area, the importance of potato increases once the altitude of the area also increases, being used as fodder for animal husbandry, due to the fact that the assortment of cultivated plants is limited to potato, rye, oat, some fruit trees, certain vegetables, while the rest of the surfaces is covered with natural pastureland and forests. In this respect, potato covers the largest surface, as corn hybrids, even early ones do not manage to reach maturity in this mountain area.

The gray mould, caused by Botrytis cinerea Pers., is an economically important disease of plants throughout the world. It is common on vegetable crops, soft fruits, ornamental plants and grapevine, and occurs in greenhouses and in the field as well as in storage and transport.

Plant extracts and their purified compounds have antibacterial, antiviral and fungicidal effects both in vitro and in vivo. Their properties were attributed mainly to alkaloids, several flavonoids and phenolic acids.

This study was made in order to establish the materials and the methods most used for the in vitro control of the fungus Botrytis cinerea Pers. with plant extracts – types of plant extracts, the most appropriate culture media, methods of inoculation, methods of extraction and methods for testing the antifungal effect of the plant extracts against the phytopathogenic fungus.

The most used medium was PDA (potato dextrose agar). Conform to the literature data this medium is the most suitable for the development of this fungus, the growth of the mycelium, the conidia growing and the formation of sclerotia.

As plant extraction method, the hydrodistilation is the most ancient method of distillation and the most versatile.

Reviewed methods used for testing the efficacy of natural products (plant extracts) were: the agar diffusion method, the poisoned food technique, the radial growth test, the conidial germination assay, the microathmosphere method, the technique of Thompson.

Effects of Ionizing Radiation on Microbiological Contaminants of Foods
Authors: BELBE Giorgiana Mihaela , TOFANA Maria
Published: December 2021

Ionizing radiation can be used in food industry in order to control the number of microbiological contaminants, among others. The sources of irradiation allowed to be used in this respect are: high-voltage electron beams up to 10 MeV, X – rays up to 5 MeV and gamma rays produced from the radioisotopes 60Co and 137Cs.

One of the most important properties of irradiation is inactivation of microorganisms, especially pathogens. Gram-negative pathogen bacteria are very sensitive to radiation. As expected bacterial spores are more resistant to ionizing radiation than vegetative cells are. Irradiation also reduces the number of mould populations. Yeasts on the other hand are more radio-resistant than bacteria and moulds and can become the dominant flora of irradiated foods. In what viruses are concerned, ionizing radiation must be accompanied by other treatments in order to be an efficient inactivation method.

In conclusion, ionizing radiation can be used, at acceptable doses, as a control method in preserving the innocuity of foods.

Many sectors rely on sun technology benefit, and so can agriculture. The productivity of these sectors depends on the amount of energy that they gather from the sun. Generally there are two types of solar systems: the ones that convert solar energy into electricity and the others that convert solar energy into heat. Both types have many applications in agriculture, helping the productivity.

Photovoltaic panels are very economy efficient regarding electricity distribution for long distance locations, like agricultural exploitations, farms, orchards, and other agricultural operations. The use of solar panels is indicated for agriculture due to easy maintenance.

Farmers don’t use only energy from the sun, its heat being also very important in agriculture. Drying cereal and other products through sun exposure is widely used.

In this paper solutions of solar radiation use nationally and internationally are presented, different methods adapted for agriculture, as well as results from researches in this field.

Assuming that the production increase is proportional to the saturation superdeficit, we get the differential equation:

where A is the saturation production, and a is the initial production. The equation above has the solution , where is the hyperbolic tangent of . It is possible to generate nomograms based on the equation determined. These nomograms can help prognosticate the agricultural production for the situations in which people choose to use only nitrogen fertilizers

The quality and safety of grocery became a consumers’ right that affects directly the quality of life. Thus, the issues referring to the safety of grocery is in the center of attention of the institutions created for protecting the customers’ best interests.

The bio milk can be defined as milk with zero quality defects. This means that the milk corresponds to all quality criteria, respectively nutritional, sanitary, bacteriologic, technologic, sensorial, and psycho-social.

The microbiological analyses that are described in the paper have the purpose of monitoring the microbiological parameters listed COMMISSION REGULATION (EC) No 1441/2007 of 5 December 2007 amending Regulation (EC) No 2073/2005 on microbiological criteria for foodstuffs and REGULATION (EC) No 853/2004 OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL of 29 April 2004 laying down specific hygiene rules for food of animal origin. The research was made during the validity period of the 3 types of milk that were studied (eco milk, UHT milk, conventional) respectively the product in the first day of validity, in the middle of the validity period and in the last day of validity.

The methods used represented both rapid and classic standardized techniques, using media of enrichment, isolation and confirmation, characteristic to each method.

After the realised determinations referring to some microbiological characteristics of the conventional and ecological milk, through the validity period were observed some alterations related to the microbiological quality of milk.

Published: December 2021

In natural plant communities are formed fungal-plant associations, associations with the increasing role of the feeding process of both partners, the fungus becoming an extension of the plant's root system, in exchange of carbohydrates synthesized by plants. Mycorrhizal associations are defined by three elements - plant root system, an intraradicular hyphal system and an extraradicular hyphal system.

The study of mycorrhizal symbiosis in controlled environments provided by a green house allows the inplementation of a sampling system in different phase of growth and development of symbiotic fungi. Analisys on samples taken were used to explain the frequency and abundance of different structure in emerging or developed the extraroot by vesicular-arbusculare mushrooms Analizele efectuate asupra probelor recoltate au fost utilizate pentru explicarea frecvenţei şi abundenţei cu care apar diferitele structuri intra- sau extraradiculare dezvolatate de către ciupercile vezicular-arbusculare.

Alpha tocopherol is recognized as inhibitor of lipid oxidation in biological systems and the intake of this vitamin is relevant to human health .Catering food products investigated in the current study have been chosen from two food groups: fish based food products and meat based food products.A number of ten food samples were investigated. Alpha tocopherol was analysed using a Shimadzu VP Series liquid chromatograph equipped with a fluorescence detector FR -10 AXL with excitation wavelength of 290 nm and emission wavelength of 325 nm.

Data analysis suggest significant loss of tocopherol in meat and fish based food product as compared to the content found in thermal non-treated preparations. Thus, in fish preparation the cook-serve processing by conventional thermal treatment diminishes the tocopherol content by 58%; in case of microwave thermal treatment this loss is 64.5 %. It was found that the microwave thermal treatment generated lower tocopherol content by 10% versus the conventional thermal treatment. In case of thermally non-treated meat preparations the tocopherol content is 0.82 mg/100g product, greater than in fish preparations, but the loss registered by conventional thermal treatment and by microwave thermal treatment is approximately 21,95%, and 25,6%, respectively. In the case of meat preparations, the microwave thermal treatment generates a loss of tocopherol content greater by 16,6 % as compared to the conventional thermal treatment.

Published: December 2021

Enzymatic hydrolysis of starch is one of the most important enzymatic technologies nowadays, leading to important amounts of sweeteners in food industry. It is accomplished at industrial scale using high starch concentrations; the present study deals with a less explored pathway, the one of low starch concentrations, originating from the residual starch in waste waters. The effective parameters of enzymatic starch hydrolysis were studied at laboratory scale, using a commercial enzymatic product (Dextrozyme® GA); experiments were carried out using low concentration starch systems, which were hydrolyzed monitoring the influence of pH, temperature, starch concentration and mixing rate on the reaction rate. Enzymatic reactions were monitored using high performance liquid chromatography, with a system enabling the quantification of glucose, fructose, saccharose and maltose. A complete factorial design at two levels was applied, the measured system’s response being the reaction rate. The obtained data demonstrated that the most important effect on saccharification is due to the pH, this being followed by starch concentration, temperature and mixing rate. Temperature, starch concentration and mixing rate are positively related with the reaction rate, while pH is inversely related with this. Analysis on the parameters’ interactions revealed that the most important interaction is the one between temperature and pH, followed by concentration-temperature and concentration-pH, while the combined interaction concentration-temperature-pH-mixing rate can be considered negligible

Lipids hydrolysis in self-microemulsifying system with lipase increases the practical approaches of emulsions as food additives with biopreservation potential. This study aimed improved bioactive functions of raw coconut fat hydrolysates using self-microemulsifying oily formulation to intensify hydrolysis yield, stabilization of compounds of hydrolysis and control antimicrobial action by controlled release in model and food systems. For microemulsions characterization has been made pseudoternary phase diagrams and have highlighted reports of mixing A / W / S / CoS corresponding states of microemulsion. Microemulsions obtained are stable and provides good stabilization of oil, up to 70% w/w water. Through viscosimetric and conductometric analysis have highlighted the transition states of micro W/O, O/W bicontinuous structures. The antimicrobial activity of microemulsions was evaluated upon spoilage microorganisms as: Bacillus subtilis, Sarcina flava, Saccharomyces cerevisiae, Rhodothorula glutinis, Candida mycoderma, Aspergillus niger, Penicillium glaucum and Geotrichum candidum. It was observed that microemulsions have a higher antimicrobial potential, comparing with classical enzymatic hydrolisates, due to large surface of contact between enzyme and oil and also due to release a large amount of saturated fatty acids with antimicrobial activity.
