Comparison of selected disinfectants efficiency against Listeria monocytogenes biofilm formed on various surfaces.

Listeria monocytogenes is a main etiological factor of listeriosis, spread mainly by food products. In recent years, an increasing number of patients with listeriosis and an augmentation in L. monocytogenes antibiotic resistance, e.

Biomechanical properties of 3D-printed bone models.

Bone lesions resulting from large traumas or cancer resections can be successfully treated by directly using synthetic materials or in combination with tissue engineering methods (hybrid). Synthetic or hybrid materials combined with bone tissue's natural ability for regeneration and biological adaptation to the directions of loading, allow for full recovery of its biological functions. Increasing interest in new production methods or various types of regenerative membranes and shaped scaffolds means that methods such as additive manufacturing can significantly accelerate the preparation of constructs used in the further biological adaptation of natural tissue.

Dynamics of phosphorus content and the activity of phosphatase in forest soil in the sustained nitrogen compounds emissions zone.

This paper summarizes research work on the seasonal and profile dynamics of phosphorus content and the activity of phosphatase in soil next to the nitrogen industry. The results are presented of the total phosphorus (TP) and available phosphorus (AP) content and the alkaline phosphatase (AlP) and acid phosphatase (AcP) against the basic physicochemical properties (clay, pH, total organic carbon, total nitrogen). Three soil profiles were sampled from Brunic Arenosols 0.

Heavy metal content and mobility in urban soils of public playgrounds and sport facility areas, Poland.

Among the threats to air, soil, and water posed by urbanization, heavy metals appear particularly hazardous. Playgrounds and sport facilities are unique urban places, widely used by children and youth. The aim of this research was to evaluate heavy metal pollution in urban soils, identify relationships among topsoil metal distributions, and assess related health risks in two Polish cities - Warsaw and Bydgoszcz.

(Cryo)conservation of Ajania pacifica (Nakai) Bremer et Humphries shoot tips via encapsulation-dehydration technique.

Unlabelled: 　　BACKGROUND: Ajania pacifica, a novelty on the horticultural market, is valued as an ornamental and a medicinal plant. Breeding programs led to the creation of numerous cultivars. Therefore, it is important to develop species storage methods.

Preparation and Characterization of Eco-Friendly Mg(OH)₂/Lignin Hybrid Material and Its Use as a Functional Filler for Poly(Vinyl Chloride).

A functional magnesium hydroxide/lignin hybrid system was prepared by grinding and mixing the pure precursors using a planetary ball mill. In addition, the thermal stability was assessed based on the total mass loss of the hybrid system within the temperature range of 30⁻1000 °C, which amounted to 38%. Moreover, the average particle size was at 4.

Correlation of carcass meat content with development of the reproductive system in sexually immature gilts.

This study evaluated the correlation of carcass meat content with the development of the reproductive system in sexually immature gilts of Polish Large White (PLW) and Polish Landrace (PL) breeds. The results, obtained from three groups (I, II, III) of gilts differing in lean meat percentage, indicate an effect on fattening and slaughtering traits as well as on the morphometric characteristics of the uterus. There were statistically significant differences in the values of fattening and slaughtering traits in the groups of gilts tested.
