We studied the effect of putrefactive decomposition of sheep hooves on the cellular composition, physical and chemical properties of blood, as well as on the biochemical composition of its serum. In the production conditions of the sheep-breeding complex, orthopedic medical examination and identification of sheep with putrefactive decay of the hooves were carried out. Subsequently, blood samples were collected from 10 sick sheep and 10 clinically healthy animals for general clinical analysis and biochemical analysis of their serum. The selected blood samples were analyzed on the haematological automatic analyser "Abacus vet 10" and the semi-automatic biochemical analyser "Stat fax 300". In the biochemical composition of blood serum, putrefactive decay of hooves increased the concentration of total protein by 7.94%, total bilirubin by 22.08%, urea by 75.18%, and reduced the concentration of glucose by 17.88% relative to clinically healthy sheep. At the same time, the activity of aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, and creatine kinase in the blood serum of sheep with putrefactive hoof decay exceeded similar indicators in clinically healthy sheep by 9.65%, 9.16%, 13.70%, and 19.90%, respectively. In addition, the concentration of sodium, potassium, calcium, phosphorus and magnesium in the blood serum of sheep with putrefactive decay of hooves was by 15.44%, 9.64%, 3.49%, 25.35% and 9.78% less than in the blood serum of clinically healthy sheep.

Proanthocyanidins represent a unique class of oligomeric and polymeric secondary metabolites found ubiquitously and in considerable amounts in plants and some algae. These substances exhibit a range of rather surprising physical and chemical properties which, once applied to living organisms, are translated into a multitude of biological activities. The latter include antioxidant properties, cancer chemoprevention, anti-inflammatory and anti-diabetic effects as well as some exceptional, yet highly interesting activities, such as anti-nutritional and antimicrobial activity. Despite the wide range of activities and possible medical/agricultural applications of proanthocyanidins, many questions still remain, including issues related to bioavailability, metabolism and the precise biochemical, extra- and intracellular targets and mode(s) of action of these highly potent materials. Among the various physical and chemical interactions of such substances, strong binding to proteins appears to form the basis of many of their biological activities. Once easy-to-use synthetic methods to produce appropriate quantities of pure proanthocyanidins are available, it will be possible to identify the prime biological targets of these oligomers, study oligomer-protein interactions in more detail and develop possible practical applications in medicine and agriculture.

Objectives: Monitoring of metabolic status in athletes includes a wide range of different parameters, but not all of them have been fully studied. Thus, the presence of oxidative stress is noted in athletes, but its features are revealed only in fragments. The crystallogenic properties of blood in athletes have not been previously studied. Methods: The study enrolled a total of 262 athletes (19–29 years old) that are highly qualified in cyclic sports. Furthermore, screening data of apparently healthy non-exercising volunteers of the same age (n=35) were used for control. Blood serum of the athletes and non-exercising volunteers was analyzed for 8-isoprostane level, oxidized low-density lipoproteins, activity of superoxide dismutase, and glutathione peroxidase and reductase. We also studied the level α- and β-carotenes, α- and γ-tocopherols, lycopene, lutein, and zeaxanthin. Crystallogenic properties of blood serum were tested with own method. Results: The complex study demonstrated the presence of shifts in oxidative metabolism and blood serum physical and chemical properties induced by professional sports and manifested both in the status of blood pro- and antioxidative systems and in shifts of biofluids crystallogenic activity. At the same time, the obtained data confirmed the development of oxidative stress in qualified athletes. Conclusion: Our data shown that there are some shifts of oxidative metabolism and crystallogenic properties of blood plasma in professional athletes.

It has long been known that materials containing cellulose fibers in their composition are destroyed by molds, microorganisms, actinomycetes, which use cellulose as a carbon source. Different fibrous materials to varying degrees (but always) are affected by molds. It is known that linseed and cotton types of paper are affected by the smallest number of fungi, and sulphate ones by the largest. The most biostable is cotton paper, the composition of which contains chalk in a sufficiently large amount. The observations carried out by the authors showed that the highest biostability (fungal resistance) is characteristic of papers containing chalk and kaolin, the lowest is glued types of paper with a high degree of sizing. Aging of paper with increasing temperature increases the overall susceptibility of all types of paper tested without exception. Obviously, changes in the physical and chemical properties of paper as a result of aging create more favorable conditions for the growth of fungi. It is well known that paper can serve as a medium for the spread of infectious diseases. The authors of the article studied the thermo-physical properties of basalt fiber and investigated the possibility of using it for the manufacture of heat-insulating technical paper.Obtaining materials that are not affected by bacteria, insects and molds (fungicidal,insecticidal) can be solved by using inorganic fibers, which are obtained from almost unlimited natural resources and which have excellent biochemical properties. It should be noted that the concept of "biocidal" paper (material) is collective. It combines species that differ in their ability to kill bacteria (bactericidal), molds (fungicidal), insects (insecticidal). Each of the biocidal types of materials has two or more of these properties.

Articular hyaline cartilage is of interest to both the clinician and the basic scientist because of its unique physical and chemical properties which are a consequence of its biochemical composition. Although it is a tissue which is hypocellular, avascular, and also lacks nerves and lymphatics, it is active in synthesis and degradation. Articular cartilage responds to the forces to which it is subjected and, in this way, maintains its integrity as long as those forces do not exceed the tissue's capacity for repair or permanently change the biologic response of the cells.

The advantages of albumin over less costly alternative fluids continue to be debated. Many scientific articles were devoted to the clinical analysis of the use of albumin in acute illness as well as its comparison with other fluid regimens. However, the lack of fundamental knowledge about the physical and chemical properties of commercial albumin generates many unpromising discussions about the effectiveness of the use of albumin among practitioners and medical scientists. The manuscript provides information about the different variants of commercial albumin, the mechanisms of their action, indications and contraindications to use. The main purpose of this article is to objectively show the failure of generalizing conclusions and recommendations on the clinical use of commercial albumin, taking into account its various physical and chemical characteristics. To date, all studies should be conducted either in the form of a comparative analysis of a specific clinical effect, or within the framework of studies of only one brand of albumin. Otherwise, generalizing the conclusions, the recommendations on the use of different forms of albumin are not correct and generate a lot of useless of the discussions. The presented information is based on fundamental knowledge of physical and chemical properties of commercial albumin. This manuscript is not only educational information, but also is scientific guide for clinicians.

In connection with the spectrophotometric study of population-type characteristics of various kinds of stars, a statistical analysis of kinematical and distribution parameters of the same stars is performed at the Toruń Observatory. This has a twofold purpose: first, to provide a practical guide in selecting stars for observing programmes, second, to contribute to the understanding of relations existing between the physical and chemical properties of stars and their kinematics and distribution in the Galaxy.

Continuing studies on the physical and chemical properties of foot-and-mouth disease virus (FMDV) have included electron microscopy of RNA strands released when highly purified virus (1) was dialyzed against demlneralized distilled water. The RNA strands were dried on formvar-carbon coated electron microscope screens pretreated with 0.1% bovine plasma albumin in distilled water. At this low salt concentration the RNA strands were extended and were stained with 1% phosphotungstic acid. Random dispersions of strands were recorded on electron micrographs, enlarged to 30,000 or 40,000 X and the lengths measured with a map-measuring wheel. Figure 1 is a typical micrograph and Fig. 2 shows the distributions of strand lengths for the three major types of FMDV (A119 of 6/9/72; C3-Rezende of 1/5/73; and O1-Brugge of 8/24/73.

Biomimetics involves investigation of structure, function, and methods of synthesis of biological composite materials. The goal is to apply this information to the design and synthesis of materials for engineering applications.Properties of engineering materials are structure sensitive through the whole spectrum of dimensions from nanometer to macro scale. The goal in designing and processing of technological materials, therefore, is to control microstructural evolution at each of these dimensions so as to achieve predictable physical and chemical properties. Control at each successive level of dimension, however, is a major challenge as is the retention of integrity between successive levels. Engineering materials are rarely fabricated to achieve more than a few of the desired properties and the synthesis techniques usually involve high temperature or low pressure conditions that are energy inefficient and environmentally damaging.In contrast to human-made materials, organisms synthesize composites whose intricate structures are more controlled at each scale and hierarchical order.
