Introduction. Medicinal plants are perfectly suited to interact with biological macromolecules like proteins and nucleic acids. All sources of natural products such as plants, microorganisms, animals, etc. are therefore biochemical potential. Aim. The goal was to present a typical plant often found in abandoned places, fields, meadows in the Podkarpacie region of Poland. Medicinal plants presented here were collected in Summer 2021 close to the city Jarosław. Material and methods. Plants collected for herbarium, immediately after harvest, are laid out between paper sheets that absorb moisture. Dried plants retain the shape of individual organs and usually also the colors. As the result of our collection, in this article are presented Papaver rhoeas L., Centaurea cyanus L., Capsella bursa – pastoris L., Taraxacum officinalle F.H., Wigg Coll and Lamium album L. Analysis of the literature. The desire to summarize information for future generations and to present the writings of the classical scholars to a wide audience was the major stimulations for presenting a most popular medicinal plants to the reader. The plants most often obtained for pharmaceutical purposes include: chamomile, fennel, St. John’s wort, nettle, mint, dandelion, yarrow, marshmallow, sage, foxglove, lemon balm, dandelion, rosehip, aloe, ginseng, and milk thistle. Conclusion. The history of plants collections is well documented.

Waste is an unwanted byproduct of human actions that physically contains the same substance as the valuable product. Waste is produced as a result of inefficient manufacturing processes, and its constant creation results in a waste of critical resources. Recycling is the conversion of waste materials into new materials and things, and a material's recyclability is determined by its ability to regain the attributes it had in its virgin or original state. Waste is divided into broad categories depending on its environmental impact (hazardous and non-hazardous waste), physical state (solid, liquid, and gaseous waste), and source. Biological reprocessing, energy recovery, and physical reprocessing are some of the waste recycling processes available. The purpose of waste management is to create sanitary living circumstances in order to limit the quantity of garbage that enters and leaves society while also encouraging the reuse of waste. Fermentation of organic waste, anaerobic digestion, bioleaching, biosorption, and bioreduction are examples of biochemical waste recycling technologies. We review to provide adequate and concise information on the biochemistry of waste management.

Pierwiastki ziem rzadkich mają bardzo interesujące właściwości biochemiczne. Dane literaturowe wskazują na to, że jony pierwiastków ziem rzadkich akumulują się w organizmach żywych praktycznie we wszystkich organach, przy czym w komórkach nowotworowych akumulują się znacznie silniej niż w komórkach zdrowych. Kompleksy pierwiastków ziem rzadkich zarówno z ligandami organicznymi, jak i nieorganicznymi są stosowane jako środki antyseptyczne, w serologii jako czynniki zmniejszające ciśnienie krwi i modyfikujące rytm serca. Są stosowane w zwalczaniu gruźlicy, jako czynniki hamujące rozwój komórek nowotworowych, jako czynniki przeciw oparzeniom chemicznym i termicznym, przeciw migrenie, epilepsji i w radioterapii.

Rare earth elements have very interesting biochemical properties. The survey of literature shows that rare earth ions are accumulated in living organisms practically in all their organs, but in the cancer cells stronger than in the healthy ones. The complexes of rare earth elements with organic ligands as well as with inorganic ones are used as antiseptic medecines, in serology as the agents reducing the blood preasure and modyfying the rythm of the heart. They are used also for healing tuberculosis, as the agent against tumor, as the agents against chemical and thermal burns, migrene, epilepsy and in radioterapeutics.

Purpose. Using databases available on the Internet, the number of scientific papers on the subject of field hockey were examined. Basic procedures. As a result, 208 scientific studies covering the fields of biochemistry, physiology, sport injuries, psychology and tactics were found, which were published within the last 50 years (from 1960 to 2010). Despite the popularity of field hockey and its status as an Olympic sport, the number of scientific studies which focused on field hockey was much smaller when compared to the amount of publications on other team sports, such as soccer, basketball, or baseball. Main findings. It was found that the greatest number of publications (61.06%) originated from five English-speaking countries (UK, USA, Canada, Australia, and New Zealand), with the majority focusing on sport psychology, injuries and biochemistry. What was discovered was that the vast majority of scientific studies used field hockey merely as a reference point in comparison to other team sports. Conclusions. The varying topic diversity of the scientific studies found among the databases significantly hinders an effective comparison of findings, especially considering that most of the studies focused on only a few selected aspects of the problem matter and were chiefly small sample studies, nor were they repeated.

The content of lead, zinc, copper, nickel and chromium in the aerial and underground parts of M. sinensis from eleven years old plantation and M. sacchariflorus and M. giganteus from nine years old plantations were analysed in order to recognize what organs of the plant play the most important function as a metal accumulator. It was found that in the aboveground parts, lead, zinc and copper were accumulated mostly in leaves and nickel and chromium in stems of the studied species. In underground plant parts, especially in roots, zinc, copper and nickel were most abundantly accumulated, while rhizomes accumulated higher amounts of lead and chromium. The content of lead, zinc and copper was definitely lower in those plant organs than their content in soil. The content of nickel and chromium, on the other hand, showed the opposite dependence. A similar capacity for uptaking trace elements from soil was observed for M. sacchariflorus and M. giganteus, while M. sinensis it was much lower, which is confirmed by the values of the bioaccumulation factors. The translocation factor for trace metals in the studied grass species indicated great translocation of lead and nickel from the roots to rhizomes, and that of zinc to aboveground parts.

Acetylcholinesterase (AChE) sequentially extracted from mature specimens of Hymenolepis diminuta was shown to be a globular protein, the monomeric form of which (Ga₁) had molecular mass of 66 kDa as determined by SDS-PAGE. Amphiphilic character of the enzyme was revealed by Triton X-l14 phase partitioning. The cestode AChE preferred acetylthiocholine over propionyl- and butyrylthiocholine as substrate, split N-acetyl-ß-methylthiocholine and myristoylcholine but did not hydrolyze ß-carbonaphthoxycholine, a substrate for butyrylcholinesterases. It was sensitive to 10⁻⁵ M physostigmine and 10⁻⁵ M BW284C51 but not to 10⁻³ M iso-OMPA. No butyrylcholinesterase activity was detected in extracts from the parasite.

The influence of iodine-iodide solution on (he biochemical and immunological properties of human thyroglobulin (hTg) were studied. Human Tg preincubated with the iodine-iodide solution is split to small molecular mass fragments after disulphide bridge reduction with dithiothreitol. The peptide bond cleavage by iodine pretreatment and reduction is possibly linked with the coupling reaction of diiodotyrosyl residues. Pretreatment of hTg with iodine-iodide solution at 1 -10 |iM decreased the binding of autoantibodies to hTg. The iodine-iodide induced inactivation of hTg autoepitopes is pH dependent and is possibly caused by iodination of tyrosyl residues present in the epitope structure.

Cysteine proteases (CPs) are responsible for many biochemical processes occurring in living organisms and they have been implicated in the development and progression of several diseases that involve abnormal protein turnover. The activity of CPs is regulated among others by their specific inhibitors: cystatins. The main aim of this review is to discuss the structure-activity relationships of cysteine proteases and cystatins, as well as of some synthetic inhibitors of cysteine proteases structurally based on the binding fragments of cystatins.
