Abstract

Background/Objectives: This study assessed the effects of 5G radiofrequency electromagnetic radiation (RF-EMR) at different frequencies (700 MHz, 2500 MHz, 3500 MHz) on the complete blood count (CBC), erythrocyte morphometry, and platelet activation after the short-term in vitro exposure of human blood. Methods: Blood samples from 30 healthy volunteers (15 men and 15 women, aged 25–40 years old) were collected at three intervals (14 days apart). For each collection, four tubes of blood were drawn per volunteer—two experimental and two controls. Experimental samples were exposed to 5G RF-EMR for 2 h at room temperature using a half-cone gigahertz transverse electromagnetic cell. The CBC was analysed via a haematology analyser, the erythrocyte morphometry was analysed using the SFORM program, and platelet activation was analysed via flow cytometry. Results: The CBC and platelet activation showed no significant differences between the experimental and control samples. However, the erythrocyte morphometry exhibited notable changes. At 700 MHz, the erythrocyte size, contour, and membrane roughness increased significantly for both sexes, with women's cells showing greater sensitivity. At 2500 MHz, women exhibited an increased contour index and a decreased solidity and form factor. At 3500 MHz, women showed an increased contour index and outline but a decreased solidity, elongation, and form factor. Cluster analysis identified two erythrocyte subpopulations: smaller, rounder cells with smooth membranes and larger cells with rougher membranes. Conclusions: These results indicate that 5G RF-EMR exposure significantly alters erythrocyte morphometry. The strongest effects were observed at 700 MHz, where men exhibited greater membrane roughness, and women showed larger and rounder erythrocytes. These findings suggest that short-term in vitro 5G RF-EMR exposure disrupts the cytoskeleton, increasing membrane permeability and deformability. [ABSTRACT FROM AUTHOR]

Abstract

Oxidative stress is implied in various pathological conditions in both humans and animals, and recent studies have suggested its role in performance, recovery, immunity, and health. This study’s objective was to investigate whether the higher frequency of activity by hunting dogs influences the oxidative stress indicators subsequent to endurance. The research involved forty-one hunting dogs, with equal representations of Alpine Brack Dachshund, Istrian Coarse-Haired Hound, and Posavina Hound. The dogs were categorized into higher frequency activity (n=22) and lower frequency activity (n=19) groups. Endurance was defined as a wild-boar hunt lasting for eight hours at an outside air temperature amounting to 10°C. Endurance had an impact on several parameters: an increased white blood cell count, neutrophils, and mean corpuscular hemoglobin concentration values, but decreased values of eosinophils and lymphocytes. Non-enzymatic biochemical indicators revealed higher energy expenditure (decreased glucose, total protein, and albumin concentration), hemoconcentration (decreased iron concentration), and elevated enzyme activity (AST, ALT, ALP, and CK-MB) but lower catalase activity. In terms of activity frequency, enzyme biomarker activity showed significant differences. ALT activity in both low- and high-frequency activity canines was notably higher (P<0.05) post-endurance compared to pre-endurance levels. ALP activity was significantly higher (P<0.05) post intense physical activity in higher frequency activity canines, yet lower (P<0.05) in lower activity frequency canines compared to their pre-endurance status. In conclusion, both tested canine groups demonstrated notable signs of oxidative stress subsequent to endurance, without differences between activity frequencies., Oksidacijski stres javlja se u raznim patološkim stanjima kod ljudi i životinja, a nedavna istraživanja sugeriraju njegov znakovit utjecaj na proizvodne pokazatelje, oporavak, otpornost i zdravlje. Cilj istraživanja bio je utvrditi utječe li veća učestalost aktivnosti lovačkih pasa na pokazatelje oksidacijskog stresa nakon dugotrajne fizičke aktivnosti. U istraživanju je sudjelovao 41 lovački pas, s podjednakom zastupljenošću pasmina alpski jazavčar, istarski kratkodlaki gonič i posavski gonič. Psi su kategorizirani u skupine koje treniraju (n=22) i skupine koje ne treniraju (n=19). Dugotrajna fizička aktivnost definirana je kao lov na divlje svinje u trajanju od osam sati, na vanjskoj temperaturi zraka od 10 °C. Dugotrajna fizička aktivnost utjecala je na nekoliko pokazatelja: broj leukocita, neutrofila i srednje vrijednosti koncentracije hemoglobina su povećani, a vrijednosti eozinofila i limfocita su snižene. Neenzimski biokemijski pokazatelji otkrivaju veću potrošnju energije (smanjena koncentracija glukoze, ukupnih proteina i albumina), hemokoncentraciju (smanjena koncentracija željeza) i povišenu aktivnost enzima (AST, ALT, ALP i CK), te nižu aktivnost katalaze. Što se tiče frekvencije aktivnosti, pojedini enzimi biomarkeri aktivnosti pokazuju znakovite razlike. ALT je i kod pasa niske i kod pasa visoke frekvencije aktivnosti bila veća (P<0,05) nakon dugotrajne fizičke aktivnosti. Usporedbom vrijednosti ALP-a nakon dugotrajne fizičke aktivnosti u odnosu na vrijeme prije dugotrajne fizičke aktivnosti, utvrđeno je da je ovaj enzim bio znakovito povišen (P<0,05) kod pasa veće frekvencije aktivnosti odnosno znakovito snižen (P<0,05) kod pasa manje frekvencije aktivnosti. Zaključno, obje testirane skupine pasa pokazale su izražene znakove oksidacijskog stresa nakon vježbe izdržljivosti, bez obzira na utreniranost.

Abstract

Nepotpuna prehrana životinja pa tako i ovaca, može dovesti do narušavanje homeostaze organizma, smanjenja proizvodnje, pojave bolesti pa i do uginuća. Vitamin D označava skupinu usko povezanih tvari koje posjeduju antirahitičnu aktivnost. Među vitaminima jedinstven je po tome što je jedini koji se u organizam ne unosi samo hranom (sijeno, a u mesojeda hrana animalnog podrijetla), već se u organizmu (koži) stvara i uz pomoć sunčeve svjetlosti. Uobičajeno je da pašno držane ovce rijetko kad trebaju dodatke vitamina D. To je stoga jer ovce ukoliko su izložene UVB zračenju, odnosno sunčevoj svjetlosti mogu nadoknaditi manjak vitamina D u hrani sintezom vitamina D unutar kože. No, ukoliko je izloženost ovaca suncu smanjena dugotrajnom naoblakom ili uzgojem u zatvorenom te kada je sadržaj vitamina D2 u hrani nizak, tada unesena količina vitamina D može biti nedostatna. U janjadi se deficit vitamina D očituje pojavom rahitisa, a u odraslih ovaca pojavom osteomalacije te hipokalcemije. U ovaca se obično javlja u kasnom graviditetu, ali je zabilježena i u životinja različite dobi. Slijedom svega navedenoga cilj je ovoga preglednoga rada je upoznati doktore veterinarske medicine s novim saznanjima o ulogama i metabolizmu vitamina D u ovaca te njegovom značenju za zdravlje i održavanje proizvodnih sposobnosti jedinke, odnosno stada., The incomplete nutrition of animals, including sheep, can lead to a disruption of homeostasis, reduced production, development of disease, and even animal death. Vitamin D refers to a group of closely related substances that possess antirachitic activity. This is the only vitamin that is not only taken into the organism by way of dietary origin (hay, food of animal origin in carnivores), but is also synthetised in the body (skin) with the help of sunlight. Typically, grazing sheep rarely need vitamin D supplements. This is because sheep can compensate for the lack of vitamin D in their food by synthesizing vitamin D in the skin if they are exposed to UVB radiation or sunlight. However, if sheep exposure to the sun is reduced by prolonged bad weather or indoor animal breeding, and when the vitamin D2 content of the diet is low, then the animal may have insufficient vitamin D consumption. In lambs, vitamin D deficiency is manifested by rickets, and in adult sheep by osteomalacia and hypocalcaemia. In sheep, this usually occurs in late pregnancy but has been observed in animals of all ages. Following the above, the aim of this review is to acquaint veterinarians with new knowledge about the roles and metabolism of vitamin D in sheep and its importance for the health and maintenance of productive abilities of the individual animal or herd.
