Plants of the genus Brassica occupy the top place among vegetables in the world. This genus, which contains a group of six related species of a global economic significance, three of which are diploid: Brassica nigra (L.) K. Koch, Brassica oleracea L., and Brassica rapa L. and three are amphidiploid species: Brassica carinata A. Braun, Brassica juncea (L.) Czern., and Brassica napus L. These varieties...

Chronic pelvic pain syndrome (CPPS) can be triggered by a various types of gynecological, gastrointestinal, urological, and musculoskeletal disorders. Recently, the role of the central nervous system has proven to be an integral part on the development of any chronic pain syndrome, including CPPS. However, owing to the complex and heterogeneous etiology and pathophysiology of CPPS, the establishment...

Mercury (Hg), a highly toxic environmental pollutant, shows harmfulness which still represents a big concern for human health, including hazards to fertility and pregnancy outcome. Research has shown that Hg could induce impairments in the reproductive function, cellular deformation of the Leydig cells and the seminiferous tubules, and testicular degeneration as well as abnormal menstrual cycles....

Accurate enumeration of Paenibacillus mucilaginosus (formerly Bacillus mucilaginosus) bacterium from environmental samples on solid medium is challenging owing to its extensive extracellular polysaccharides (EPS) excretion. In the present study, P. mucilaginosus enumeration has been facilitated by a simple modification: addition of triphenyl tetrazolium chloride (TTC) to growth medium and application...

The effects of P. aquilinum alcoholic extract on germination, growth and development of P. pratensis seedlings were examined. The extract decreased the germination and seedling growth, decreased chlorophyll, caretenoid and protein content depending on the extract concentration. Increasing concentrations decreased all these parameters proportionately simulating the effects of allelopathy in ecosystem...

Background The use of natural products based on aqueous extract of propolis and lycopene in the skin's protective mechanisms against UVA radiation was evaluated by means of experimental acute inflammation on rat paw edema. The aim of the present study was to evaluate the harmlessness of propolis - lycopene system through evaluation of skin level changes and anti-inflammatory action. The regenerative...

Dye pollution in waste waters causes serious environmental and health risk, legislation problems and is a serious challenge to environmental scientists. In this work the treatment of waste waters resulted from ink jet cartridges manufacturing, using different nanocrystalline ferrites MIIFe2O4 (MII = Mg, Cu) as adsorbent materials, has been investigated. The ferrites were obtained by thermal decomposition...

Natural herbicides may be more sustainable than their chemical homologues, but they are still toxic substances that can affect humans and animals. Implementation of natural herbicides may require just as many safety precautions as the application of commercial herbicides, hence the need not to confuse the term "organic" with "non toxic". Allelopathy is accomplished through chemical...

As an interface between the earth’s crust, atmosphere, and hydrosphere, soil is a non-renewable resource that has multiple functions: biomass production, storage, filtration, and transformation of organic and mineral matter; source of biodiversity, habitats, species, and genes; environment for humans and their activities; and source of raw materials. Impact of pollution on soil quality has increased...

The paper examines the benefit of bread enriched with antioxidants on oxidative stress, and on the quantities of hydrosoluble antioxidants in a group of human subjects. The home–management of functional foods strategy seeks to improve prompt and effective basic nutrition using additional attributes that are directly positively beneficial for health and well–being. The purpose of this clinical study...

Background. The blackcurrant (Ribes nigrum L.) is a species of native currant which contains a lot of polyphenolic antioxidants which is used medicinally and has a fundamental role in the maintenance health. Materials, methods and objective. Ultraviolet–visible spectrophotometry and ultraviolet range high performance liquid chromatography (HPLC) were used to characterize the polyphenolic content of...

Vegetables and their products (salads, fermented and nonfermented pickles, prepared sauces, and pickled, conserved, frozen, marinated, and dried vegetables) are a good source of compounds that are involved in pharmacodynamic activity. Humans are inseparably linked to the existence of vegetables, as they are the source of several bioproducts essential for the survival of the animal kingdom. The importance...
article
Background The purpose of the study is to develop a suitable analytical method in order to establish appropriate conditions for isolation and assay of the dominant compounds in extracts of Capsicum annuum. Results The studies are performed with standard substances to establish the HPLC conditions for complete separation of capsaicin and dihydrocapsaicin, the two major components of interest. Because...

Background This study aimed to quantify the allelopathic potential of Datura stramonium (Jimson weed). Sorghum halepense (Johnsongrass) tolerance was assessed by germinating, seed and growing seedlings, dosing of photo-synthesis pigments, followed by treatment with D. stramonium extract tropane alkaloids. Results Preliminary chemical analysis of the extracts showed the presence of alkaloids. The presence...
article
Background This study aimed to quantify the active biological compounds in C. officinalis flowers. Based on the active principles and biological properties of marigolds flowers reported in the literature, we sought to obtain and characterize the molecular composition of extracts prepared using different solvents. The antioxidant capacities of extracts were assessed by using spectrophotometry to measure...

Background Organosulfur compounds usually present a reduced stability especially in the presence of oxygen. This research aimed to study the stability and antioxidant potential of the Allium ursinum watery extract. Results The decrease of the antioxidant capacity verifies an exponential relation which may be formally associated to a kinetically pseudomonomolecular process. The exponential regression...

The objective of the study was to summarize the methods for isolating and identifying natural sulfur compounds from Allium ursinum (ramson) and to discuss the active constituents with regard to antifungal action. Using chromatographic techniques, the active constituents were isolated and subsequently identified. Analyses by high-performance liquid chromatography (HPLC) suggested that these compounds...

Bortezomib is the first therapeutic agent designed to inhibit mainly the activity of the 26S proteasome. It is used for the treatment of multiple myeloma. The objective of this study was to develop and optimize liposomal formulation of bortezomib in order to improve the encapsulation efficiency. For evaluating the encapsulation efficiency it was investigated the effect of two parameters: the drug/lipid...

A QuEChERS in house method for determining the marker residue of eprinomectin (eprinomectin B1a) by HPLC-FLD in bovine tissues and milk provided from treated animals was developed and applied. Briefly: all samples were extracted with acetonitrile using a dispersive SPE purification stage. The ascertained detection limits were 1 μg kg-1 and the quantification limits 2 μg kg-1. Recoveries on tissue...
