Antimicrobial activity of bee-collected pollen and beebread: State of the art and future perspectives
(2020)Bee-collected pollen (BCP) is a well-known functional food. Honey bees process the collected pollen and store it in the hive, inside the comb cells. The processed pollen is called beebread or ambrosia and it is the main ... -
Assessment of remediation of soils, moderately contaminated by potentially toxic metals, using different forms of carbon (charcoal, biochar, activated carbon). Impacts on contamination, metals availability and soil indices
(2022)The present study aims to assess the effect of three forms of carbon, i.e., charcoal, biochar and activated carbon using as soil amendments (or soil conditioners) in two soils, an acid and alkaline one. For this purpose, ... -
Bioaugmentation of animal feces as a mean to mitigate environmental contamination with anthelmintic benzimidazoles
(2021)Anthelmintics are used to control infestations of ruminants by gastrointestinal nematodes. The limited metabolism of anthelmintics in animals result in their excretion in feces. These could be piled up in the floor of ... -
Bioavailability and health risk assessment of potentially toxic elements in Thriasio Plain, near Athens, Greece
(2017)Elevated concentrations of potentially toxic elements (PTEs) are usually found in areas of intense industrial activity. Thriasio Plain is a plain near Athens, Greece, where most of the heavy industry of the country has ... -
Bioavailability and risk assessment of potentially toxic elements in garden edible vegetables and soils around a highly contaminated former mining area in Germany
(2017)Although soil contamination by potentially toxic elements (PTEs) in Europe has a history of many centuries, related problems are often considered as having been dealt with due to the enforcement of tight legislations. ... -
Bioavailability and toxicity of heavy metals in the presence of natural organic matter
(2006)The effect of humic acids (HA) on the toxicity of copper, zinc and lead was investigated in this study, using the photobacterium Vibrio fischeri (Microtox test) as a test organism. The metal species and the complexation ... -
Bioavailability, Efficacy and Safety of Generic Immunosuppressive Drugs for Kidney Transplantation: A Systematic Review and Meta-Analysis
(2016)Background: Concerns exist over the extrapolation of bioavailability studies of generic immunosuppressive drugs in healthy volunteers, regarding their efficacy and safety in kidney transplant recipients. We conducted a ... -
Biosolids application affects the competitive sorption and lability of cadmium, copper, nickel, lead, and zinc in fluvial and calcareous soils
(2017)The objective of this research was to investigate the effects of biosolids on the competitive sorption and lability of the sorbed Cd, Cu, Ni, Pb, and Zn in fluvial and calcareous soils. Competitive sorption isotherms were ... -
Biowastes alone and combined with sulfur affect the phytoavailability of Cu and Zn to barnyard grass and sorghum in a fluvial alkaline soil under dry and wet conditions
(2019)Management of degraded soils (i.e., metal contaminated soils, salt affected soils, and soils with low organic matter content) by applying biowastes (e.g., biosolids and compost) and inorganic soil amendments such as sulfur ... -
Challenges in microbially and chelate-assisted phytoextraction of cadmium and lead – A review
(2021)Cadmium (Cd) and lead (Pb) are ubiquitously present in surface soils, due to anthropogenic activities, causing threat to ecological and human health because of their carcinogenic nature. They accumulate in large quantities ... -
CONCENTRATIONS AND BIOAVAILABILITY OF POTENTIALLY TOXIC ELEMENTS IN SOILS OF AN INDUSTRIALISED AREA OF NORTHWESTERN GREECE
(2010)Thirty eight surface soil samples from the Ptolemais-Kozani basin, northwestern Greece were collected and analysed for their content in twenty three elements (Al, Ca, Fe, K, Mg, Mn, Na, Ti, As, Ba, Cd, Co, Cr, Cu, Li, Mo, ... -
The effect of coagulation on the toxicity and mutagenicity of reclaimed municipal effluents
(2006)The objectives of this work were the assessment of the effectiveness of coagulation on the reclamation of secondary effluents and the evaluation of the quality of reclaimed waters by the examination of their ecotoxic and ... -
Effects of sheep bone biochar on soil quality, maize growth, and fractionation and phytoavailability of Cd and Zn in a mining-contaminated soil
(2021)Biochar prepared from various feedstock materials has been utilized in recent years as a potential stabilizing agent for heavy metals in smelter-contaminated soils. However, the effectiveness of animal bone-derived biochar ... -
Green remediation of toxic metals contaminated mining soil using bacterial consortium and Brassica juncea
(2021)Microorganism-assisted phytoremediation is being developed as an efficient green approach for management of toxic metals contaminated soils and mitigating the potential human health risk. The capability of plant growth ... -
Heroin-induced changes of catecholamine-containing particles in male rat cerebellar cortex
(2001)The content and distribution of catecholamine-containing formations in the cerebellum of untreated and heroin-treated male rats, was visualized by glyoxylic acid-induced histofluorescence, in an attempt to define the ... -
Hexavalent chromium availability and phytoremediation potential of Cichorium spinosum as affect by manure, zeolite and soil ageing
(2017)Cichorium spinosum (spiny chicory) is a wild edible vegetable, and a possible suitable species for Cr(VI)-phytoremediation. There are three approaches for altering Cr(VI) dynamics: reduction to Cr(III) by organic matter ... -
In vitro and in vivo assessment of vitamin A encapsulation in a liposome–protein delivery system
