Résumé :

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 in

Résumé :

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 de

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.

The problem of ozone depletion has recently become a topic of major concern. What was once a vague, theoretical hypothesis that artificial chlorofluorocarbon compounds could accumulate in the stratosphere and break down ozone molecules is an imminent reality. A decrease in the concentration of stratospheric ozone would increase the amount of ultraviolet radiation in ambient sunlight. In addition to altering plant and aquatic life in unpredictable ways, increiased ultraviolet radiation will adversely affect human health.

Abstract The carcinogenic potential of UV radiation (the primary cause of nonmelanoma skin cancer) is associated with its ability to suppress cell-mediated immune responses. Previous studies have shown that this UV-induced immune suppression is caused by the secretion of immunosuppressive cytokines such as IL-10. Because the effects of IL-10 on the immune response are countered by IL-12, we injected irradiated mice with IL-12 to determine whether it could overcome UV-induced immune suppression. Administration of IL-12 blocked the suppression of delayed-in-time hypersensitivity reactions observ

Résumé :

Long-term exposure to a relatively high concentration of airborne bacteria emitted from intensive livestock houses could potentially threaten the health and welfare of animals and workers. There is a dual effect of air sterilization and promotion of vitamin D synthesis for the specific bands of ultraviolet light. This study investigated the potential use of A-band ultraviolet (UVA) tubes as a clean and safe way of reducing airborne bacteria and improving calf health. The composition and emission characteristics of airborne bacteria were investigated and used to determine the correct operating

Résumé :

One of the most important tasks of veterinary practice is to find and develop an effective and environmentally friendly method of disinfecting livestock room air that can be used in the presence of animals and service personnel. Currently, low-pressure discharge lamps are used for indoor air sanitation as a source of ultraviolet (UV) radiation. However, these devices can pose serious environmental pollution risks. Therefore, the main objective of this work was to investigate the bactericidal effectiveness of pulsed broadband optical radiation on the microbial contamination of the house air of

Abstract The exposure of experimental animals to the inflammatory effects of ultraviolet radiation (UVR) is known to cause depressions in their ability to initiate and effectuate various types of cellular immune responses. Contact-type and delayed-type hypersensitivity, plus the ability to generate protective forms of anti-viral and anti-tumor immunity, are all affected by the prior exposure of normal animals to the effects of this physical agent. Presently, the cellular and molecular mechanism(s) responsible for mediating the changes in immune function observed in UVR-exposed animals is not f

Ultraviolet B (UVB) exposure is the main cause of skin damage leading to photoaging, increasing Reactive Oxygen Species (ROS) and triggering the production of Matrix metalloproteinase-1 (MMP-1) enzymes that play an important role in photoaging, describing clinical signs including wrinkles, thickening, dryness and pigmentation. Astaxanthin can inhibit ageing and reduce wrinkles, has strong antioxidant potential that can neutralize ROS, and suppress MMP-1 activity. The purpose of this study was to determine the effect of astaxanthin cream on the levels of MMP-1 and Superoxide Dismutase (SOD) enz

Résumé :

The boreal–alpine treeline is a fine-spatial heterogeneous ecotone with small single trees, tree clusters and open snow surfaces during wintertime. Due to climate change and decreased grazing of domestic animals, the treelines expand both upwards into the mountains and northwards into the tundra. To quantify and understand the biophysical radiative climatic feedback effect due to this expansion, it is necessary to establish measurement strategies of fine-spatial albedo by which relationships with the tree structure and snow-masking effect can be quantified.

Mesquite pod flour produced from nitrogen-fixing trees of the Prosopis species has a unique aroma and flavor that is preferred by some consumers. Due to the presence of wildlife, grazing domestic animals, and insects, the pods have a high potential of being contaminated with human pathogenic bacteria, such as Bacillus cereus. Nonthermal processing technologies are helpful to reduce the population of microorganisms in the flour because heating deteriorates the characteristic flavor.
