The effectiveness of iron oxide nanoparticles in enhancing crop plant development depends on their stabilization. In this study, the effect of hyaluronic acid (HA), used both as a stabilizer for iron oxide nanoparticles (HA-MNP) and independently, was evaluated in maize seedlings. Different concentrations of HA-MNP (0.625–7.5 mg/L) were tested alon...

Rhus typhina, an invasive plant species, contains valuable compounds that can be utilized in various fields. The main aim of this paper was to find the optimal conditions for extracting high amounts of bioactive compounds from R. typhina fruits using ultrasound-assisted and bead-beating techniques under different parameters (solvent concentration,...

Ailanthus altissima, a highly invasive species, contains valuable compounds in different plant parts, indicating great practical potential. This paper proposes the use of non-polar (n-hexane) and polar (ethanol) solvents for the extraction of antioxidant compounds from A. altissima (family Simaroubaceae) leaves in a sequential two-step process. Fre...

Ailanthus altissima, an invasive plant species, exhibits pharmacological properties, but also some allergic effects on humans. This study aimed to evaluate the potential toxicity of A. altissima leaves, using a complex approach towards different organisms. The ecotoxic impact of a crude extract was investigated on seeds germination and brine shrimp...

Simple Summary Ectoparasites such as ticks, mites, fleas, and lice are ubiquitous in nature and parasitise a plethora of species ranging from small rodents to large mammals and even humans. Besides their parasitic effects, they also act as vectors for various infectious agents affecting the hosts. Parasite-borne infectious diseases have been and re...

From a public health perspective, the monitoring of water quality intended for human consumption belongs to the operational and audit management of the supply zones. Our study explores the spatial and temporal patterns of the parameters of drinking water in Sibiu County, Romania. We related the relevant physical-chemical parameters (ammonia, chlori...

Coffee is one of the most popular and consumed beverage worldwide both for the organoleptic characteristics and for the bioactive compounds’ content. Previous studies have shown that despite some risks it brings to health, it is useful in preventing cardiovascular diseases, liver diseases and hyperglycemia, and adding creams based on milk proteins...

Rhus typhina L. (staghorn sumac) represents a valuable species in terms of its medicinal properties and its wide variety of uses, which deserves more attention in the scientific world. Its fruits contain important amounts of anthocyanins, vitamins, minerals and essential amino acids, while gallic acid and several hydrolyzed tannins are produced by...

Looking for pharmaceutical remedies that are cheaper, handy, and gentle with the body, the villagers rediscover phytotherapy and practice traditional medicine in which plants play a major role. Unfortunately, much of the knowledge about herbs has been lost in recent decades. With this study, we try to save from the loss of some of the information o...

Microwaves have been frequently applied for extraction of bioactive compounds of different origin, using systems operating at 200-1000 W power, the efficiency being related to the heating of molecules. This study investigated the effects of non-thermal microwaves at 1.7 and 2.5 GHz for different exposure time, on the phenolic content and antioxidan...

Microwave (MW) irradiation in reactors with input power levels of 200-1000 W has been frequently applied for the extraction of natural compounds from vegetal material. The aim of the present research was to investigate the effect of much lower MW input powers (< 12 W) delivered through antennas into shielded enclosures on mixtures of ethanol soluti...

Invasive plant species may cause not only several health problems, but also economic and environmental negative impacts – a gradual decrease of biodiversity and decline of soil fertility, issues that have recently come into the attention of several organizations including the research ones, in order to limit the spread of such species. The control...

Protection of natural areas by restricting human activities aims to preserve plant and animal populations and whole communities, ensuring the conservation of biological diversity and enhancement of ecosystem services. Therefore, it is expected that the longer the protection, the stronger the desired effects. We evaluated the responses of small mamm...
