Abstract:
Spray-dried animal plasma (SDAP) is widely used in diets of domestic animals to improve health status and increase growth and feed efficiency. Individual steps in the SDAP manufacturing process, including spray-drying, have been validated to inactivate potential pathogens. Manufacturing standards have established a minimum exit temperature of 80°C and a minimum post-drying storage period of 14 days at 20°C for production of SDAP. Also, UV-C irradiation has been evaluated as another inactivation step that could be included in the manufacturing process. The aim of this study was to assess the inactivation effectiveness of spray-drying on Classical swine fever virus (CSFV) and African swine fever virus (ASFV) and the effect of UV-C inactivation on ASFV as redundant biosafety steps of the manufacturing process for producing spray-dried porcine plasma (SDPP). This study demonstrated that UV-C treatment of liquid porcine plasma can inactivate more than 4 Log10 TCID50/mL of ASFV at 3000 J/L. Spray-drying effectively inactivated at least 4 Log10 TCID50/mL of both CSFV and ASFV. Incorporating UV-C technology within the SDAP manufacturing process can add another biosafety step to further enhance product safety.

Abstract:
Vitamin D is an important hormone that can be acquired through diet, exposure to ultraviolet B (UVB) radiation, or a combination of these methods. In domestic rabbits (Oryctolagus cuniculus), both methods appear viable, but there is limited research evaluating the effects of UVB on this species. Previous studies found that 12 h of artificial UVB radiation significantly increased 25-hydroxyvitamin D3 (25-OHD3) concentrations over time. While these findings suggest UVB can be beneficial in rabbits, this form of radiation can also be detrimental to vertebrates. The purpose of this study was to determine if shorter-duration UVB could elicit a similar physiological response in rabbits while minimizing potential negative effects. Six rabbits were used for this pilot study. The baseline serum 25-OHD3 was measured for each rabbit and following 14 days of 6 h/day exposure to artificial UVB, a second 25-OHD3 sample was collected. There was a significant increase (p = 0.001) in serum 25-OHD3 over time (Baseline: 27.7 ± 8.1 nmol/L; Day 14: 79.8 ± 9 nmol/L). This study affirmed that 6 h of UVB produced 25-OHD3 concentrations similar to those found in rabbits exposed to 12 h of UVB. Future studies should continue to determine how the duration of UVB exposure affects 25-OHD3 concentrations.

Abstract:
Water treatment and reuse are fundamental because of the increasing demand for freshwater, especially in agriculture. Accordingly, this study evaluated the effects of turbidity of wastewater processed at the Effluent Treatment Station (ETE) of the UFSCar/Araras and of UV dose on microbial inactivation. The ETE treats up to 2000 L of wastewater daily from toilets and a university restaurant and has five components (grease box, septic tank, microalgae tank, upflow anaerobic filter, and wetlands). Pretreated effluents were used in the experiments, and sampling sites consisted of inspection boxes located after the wetlands. Sample collection, inspection, preservation, and analyses were performed according to standard methods. Sample turbidity was adjusted to 5, 50, 100, 200, and 300 nephelometric turbidity units (NTU), and UV doses of 7.2–28.8 mWs cm-2 were used. A 5 x 5 factorial design (five turbidity levels and five radiation doses) was used, totaling 25 treatments. Each treatment was performed in triplicate. The data were submitted to analysis of variance and Tukey’s test. The results showed that the increase in turbidity significantly decreased disinfection efficiency in samples with turbidity levels higher than 50 NTU. The microbial inactivation coefficients obtained here can be extrapolated to disinfection of wastewater with turbidity up to 300 NTU to eliminate thermotolerant coliforms. The UV sterilizer is feasible for wastewater treatment and its reuse in agriculture. Keywords: domestic effluent, sustainability, ultraviolet radiation, water reuse.

Abstract:
Modern technologies for the production of livestock products provide for long-term keeping of young animals indoors with an artificial microclimate. That is, it is expected to maintain within the required limits of temperature, humidity, gassiness, lighting level, etc. In particular, to compensate for solar radiation, ultraviolet irradiation units are used. The main criterion of UV irradiation is the dose, which is individual for each species and age of animals. The obtained amount of irradiation depends on the type and power of the radiation source, the height of the suspension, the continuance of the irradiation process. Therefore, existing mobile UV irradiators need to be upgraded for efficient operation. The purpose of the study is to develop a UV irradiation system for a room with pigs of different ages and weights in pens with the possibility of automatically providing the required dose. In order to increase the accuracy maintenance of the recommended dose of UV radiation, the authors use a video camera and a device with software that fulfils the effect of "pattern recognition" and automatic control of the installation during its movement over animals, which are kept in boxes in different age groups. Experimental studies showed that in the experimental groups of pigs, where irradiation was carried out using the developed unit of automatic control of the UV installation, the set of live weight in piglets was 20-25 % more than in the control group.

Abstract:
Plants are photosynthetic organisms that depend on sunlight for energy. Besides photosynthetically active radiation (PAR; 400-700 nm), plants are exposed to ultraviolet radiation, which consists of UV-C (below 280 nm), UV-B (280-320 nm) and UV-A (320-400 nm). Plants respond differently to exposure to low or high doses of ultraviolet light, either by stimulating protective mechanisms, or by activating recovery mechanisms to cope with various types of stress. (Research purpose) The research purpose is in providing an overview of the reactions of plants to ultraviolet radiation, make a relationship between the different ranges of ultraviolet radiation, radiation doses and the effect on plants. (Materials and methods) The article presents an analysis of domestic and foreign articles on the effectiveness of plant irradiation with ultraviolet radiation. (Results and discussion) Authors examined the effects of various ranges of ultraviolet radiation on plants. It was found that some properties of plants can be enhanced with small doses of UV-C, but UV-C strongly inhibits plant growth. Exposure to UV-B causes morphological and anatomical changes in plants: an increase in branching, a decrease in internodes, twisting of leaves, a decrease in leaf area, an accumulation of screening pigments, thickening of leaves, redistribution of chlorophyll. The effects of UV-B and UV-C also affect the volatiles emitted by aromatic plants. Ultraviolet-A can improve the nutritional qualities of green crops without adversely affecting plant growth. (Conclusions) It was found that ultraviolet radiation, depending on the range, has both a harmful effect on plants and a beneficial one. It was found that with certain doses of ultraviolet radiation, the necessary qualities and properties of plants could be obtained.

Abstract:
The search and development of methods for correction of oxidative stress in conditions of exposure to adverse environmental factors is an actual problem of modern medicine. In experimental conditions the possibility to correct free radical lipid oxidation of rats’ cell membranes was studied with the external application of the ointment of herb convolvulus and of the ointment of herb chickweed. The animals were divided into 4 groups and each of them had 20 rats: intact animals which were held in standard conditions of vivarium; the control group in which rats were exposed to ultraviolet radiation during three minutes daily; the experimental group in which before ultraviolet radiation animals had a daily external application of the ointment of herb convolvulus; the experimental group in which before ultraviolet radiation animals had a daily external application of the ointment of herb chickweed. It was found out that in the blood of experimental animals a daily ultraviolet radiation during three minutes contributes to the increase of lipid hydroperoxides level (by 15-19%), of diene conjugate (by 14-16%), and of malonic dialdehyde (by 40-66%) against the decrease of antioxidant system activity in the blood of intact animals. The introduction of the ointment of herb convolvulus and of the ointment of herb chickweed to rats in the conditions of oxidative stress contributes to the reliable decrease in the blood of lipid hydroperoxides by 9-13%, of diene conjugates by 8-13%, malonic dialdehyde by 15-28% in comparison with the rats of the control group. While analyzing the effect of the ointment on the activity of the components of antioxidant system it was shown that the level of ceruloplasmin in the blood of animals was significantly higher by 13-20%, of vitamin E by 8-14%, of catalase by 13-28% in comparison with the same parameter of the rats of the control group. So, the application of the ointment of herb convolvulus and of the ointment of herb chickweed in the conditions of oxidative stress induced by the influence of ultraviolet rays leads to the stabilization of the processes of peroxidation against the increase of antioxidant system activity.

Abstract:
Relevance. One of the main components of the spectrum of sunlight is ultraviolet rays – invisible to the human eye short-wave radiation. The influence of these rays on plant life was considered insignificant until recently, but recent studies have shown the fallacy of such conclusions. Ultraviolet has a beneficial effect not only on the human body and animals, but also on plants, including – crops. The destruction of the ozone layer is currently continuing under the influence of anthropogenic factors. In this regard, the study of the effect of ultraviolet radiation on living organisms, including plants, is very relevant from both theoretical and practical points of view. The epidermis of plant leaves and seed shells are permeable to medium-and long-wave UV radiation, so of particular interest is the ultraviolet radiation of the Sun and artificial sources of ultraviolet radiation in the range of 400...180 nm.Purpose of work: to assess the nature of the impact of ultraviolet radiation in the time mode on watermelon seeds using cytogenetic analysis.Methods. The material for research was the seeds of the watermelon variety "Astrakhan". The studies were conducted in 2017-2018.Results. The results of studies have shown that long-term exposure to ultraviolet radiation can affect the physiological processes and anatomical structure of plants, as well as have serious genetic changes: aneuploidy, cytotomy, pyknosis and various chromosomal aberrations that lead to mutations or death of plants. However, plants acquire useful mutations with short-term exposure-0.5-2 hours, which can be used later in selection.

Abstract:
The search and development of methods for correction of oxidative stress in conditions of exposure to adverse environmental factors is an actual problem of modern medicine. In experimental conditions the possibility to correct free radical lipid oxidation of rats’ organism membranes was studied with the introduction of the succinic acid and of the succinate containing medication called Reamberin (Polysan, St. Petersburg). The animals were divided into 4 groups and each of them had 20 rats: the group with intact animals which were held in standard conditions of vivarium; the control group in which rats were exposed to ultraviolet radiation during three minutes daily; the experimental group in which before ultraviolet radiation animals had a daily intraabdominal intake of the succinic acid in a dose of 100 mg/kg; the experimental group in which before ultraviolet radiation animals had a daily intraabdominal intake of Reamberin in a dose of 100 mg/kg (20 ml/kg). It was found out that in the blood of experimental animals a daily ultraviolet radiation during three minutes contributes to the increase of lipid hydroperoxides level (by 48-53%), of diene conjugate (by 43-48%), and of malonic dialdehyde (by 48-61%) against the decrease of antioxidant system activity in the blood of intact animals. The introduction of the succinic acid to rats contributes to the significant decrease in the blood of lipid hydroperoxides by 15-16%, of diene conjugates by 9-16%, and of malonic dialdehyde by 15% in comparison with the rats of the control group. The introduction of the succinate containing Reamberin to rats in the conditions of oxidative stress contributes to the significant decrease of lipid hydroperoxides in the blood by 27-28%, of diene conjugates by 23-28%, and of malonic dialdehyde by 26-29% in comparison with the rats of the control group. While analyzing the effect of the succinate containing drugs on the activity of the components of antioxidant system it was shown that the level of ceruloplasmin in the blood of animals was significantly higher by 25-32%, of vitamin E by 28-33% in comparison with the rats of the control group. So, the application of the succinate containing antioxidants in the conditions of ultraviolet radiation under experiment leads to the stabilization of the processes of peroxidation against the increase of antioxidant system activity. The intraabdominal introduction in laboratory animals of Reamberin in a dose of 100 mg/kg of succinate prevents the accumulation of lipoperoxidation products and increases the activity of main components of the antioxidant system in rats’ blood plasma, which indirectly exceeds similar effect of succinic acid in a dose of 100 mg/kg in the conditions of oxidative stress.

Abstract:
Background: Squamous cell carcinoma (SCC) is a malignant neoplasm associated with prolonged exposure to ultraviolet light and lack of skin pigment in white-coated animals. The disease diagnosis is based on the animal's history, clinical signs and histopathology of the samples collected. The therapeutic alternatives are diverse. Among them, one of the most used is the metronomic chemotherapy which is based on the use of cytostatics drugs, applied in low and frequent doses for a longer period of time. One of the mechanisms of action of this type of therapy is the decrease in angiogenesis. Non-steroidal anti-inflammatory drugs (NSAIDs) are simultaneously used to maximize the angiogenic effect. The objective of this study is to report the results of a treatment accomplised with metronomic chemotherapy (cyclophosphamide with meloxicam) in a domestic feline which presented a squamous cell tumor. Case: A female domestic feline, mixed breed, not neutered, weighing 3.5 kg, about 7 years old, was assisted at the Veterinary Specialties Teaching Clinic (CEEV) of the Technical University of Machala (UTMACH), presenting bilateral ulcerative lesion in the nasal plane for 5 months. Chronic exposure to sunlight is referred to in the patient's anamnesis. Aspiration cytology performed in the patient revealed an inflammatory process with a predominance of neutrophils and macrophages, and showed absence of neoplastic cells. A treatment based on antibiotics and corticosteroids was adopted. Discussion: The diagnosis of squamous cell carcinoma was based on clinical and histopathological findings. The macroscopic lesions were crusted ulcers that do not heal in the nasal plane and auricular pavilion, as reported in the literature. SCC is characterized by the infiltration of squamous cells in the dermal layer of the skin, forming epithelial islands with keratin pearls. The histopathological findings of this case present the same characteristics. The climatic conditions of Ecuador, high temperatures with greater incidence of sunlight, hypopigmented areas of the animal's body and chronic exposure to solar radiation are risk factors present in this case that foster the development of this malignant neoplasm. There are multiple treatments to be introduced in this sort of pathology. In this case, surgical removal of the tumor was adopted, followed by metronomic chemotherapy based on cyclophosphamide at 10 mg/m2 and meloxicam at a 0.05 mg/kg per day for a period of time of five months, obtaining favorable results and absence of recurrence. Despite metronomic chemotherapy being easy to administer, with fewer side effects, which includes a better acceptance of care takers who are reluctant to administer conventional chemotherapy, further studies are still necessary in what concerns certain variables such as age, carcinoma level, appropriate dosages and drugs according to each neoplasm.

Abstract:
When contagious diseases occur, there is a tangible threat of rampant spread of infection, incurring huge economic losses in animal deaths and decreased animal productivity. Thus, preventing pathogenic flora concentration in rooms where birds and animals are raised from exceeding permissible levels ranks first among veterinarian and sanitary concerns. When birds are kept on the floor during feeding, germ and dust concentration increases nine to ten times against normal. Ample research shows that ultraviolet (UV) radiation possessing a bactericidal effect is the most promising and environmentally friendly method of cleansing the air from harmful germs.
