The effect of 6GHz radiofrequency electromagnetic radiation on rat pain perception.

This paper presents data on pain perception in rats exposed to 6 GHz radiofrequency electromagnetic radiation (RF-EMR). Rats were divided into two groups: control (n = 10, 4 replicates per test) and RF-EMR exposed group (n = 10, 4 replicates per test). Nociceptive responses of the groups were measured using rodent analgesiometry. Rats were divided into control and RF-EMR exposed groups. Nociceptive responses were measured using rodent analgesiometry. RF-EMR exposed rats had a 15% delay in responding to hot plate thermal stimulation compared to unexposed rats. The delay in responding to radiant heat thermal stimulation was 21%. We determined that RF-EMR promoted the occurrence of pressure pain as statistical significance by + 42% (p < 0.001). We observed that RF-EMR exposure increased nociceptive pain by + 35% by promoting cold plate stimulation (p < 0.05). RF-EMR exposure did not affect thermal preference as statistical significance but did support the formation of pressure pain perception.

In this study, we present data on pain perception in rats exposed to 6GHz RF-EMR. RF-EMR exposed rats showed delayed responses to hot plate and radiant heat thermal stimulation. RF-EMR increased pressure and nociceptive pain as statistically significance. In particular, the effects of RF-EMR should be considered when assessing hyperalgesic and hypoalgesic symptoms in the clinic. The results of this study indicate the need to take precautions against the possible negative effects of RF-EMR on human health with the rise of 5G technology.

Long-term effect of indomethacin on a rat model of neonatal hypoxia ischemic encephalopathy through behavioral tests.

BACKGROUND: Many medical experts prescribe indomethacin because of its anti-inflammatory, analgesic, tocolytic, and duct closure effects. This article presents an evaluation of the enduring impact of indomethacin on neonatal rats with hypoxic-ischemic (HI) insults, employing behavioral tests as a method of assessment. METHODS: The experiment was conducted on male Wistar-Albino rats weighing 10 to 15 g, aged between seven and 10 days. The rats were divided into three groups using a random allocation method as follows: hypoxic ischemic encephalopathy (HIE) group, HIE treated with indomethacin group (INDO), and Sham group. A left common carotid artery ligation and hypoxia model was applied in both the HIE and INDO groups. The INDO group was treated with 4 mg/kg intraperitoneal indomethacin every 24 h for 3 days, while the Sham and HIE groups were given dimethylsulfoxide (DMSO). After 72 h, five rats from each group were sacrificed and brain tissue samples were stained with 2,3,5-Triphenyltetrazolium chloride (TCC) for infarct-volume measurement. Seven rats from each group were taken to the behavioral laboratory in the sixth postnatal week (PND42) and six from each group were sacrificed for the Evans blue (EB) experiment for blood-brain barrier (BBB) integrity evaluation. The open field (OF) test and Morris water maze (MWM) tests were performed. After behavioral tests, brain tissue were obtained and stained with TCC to assess the infarct volume. RESULTS: The significant increase in the time spent in the central area and the frequency of crossing to the center in the INDO group compared with the HIE group indicated that indomethacin decreased anxiety-like behavior (p < 0.001, p < 0.05). However, the MWM test revealed that indomethacin did not positively affect learning and memory performance (p > 0.05). Additionally, indomethacin significantly reduced infarct volume and neuropathological grading in adolescence (p < 0.05), although not statistically significant in the early period. Moreover, the EB experiment demonstrated that indomethacin effectively increased BBB integrity (p < 0.05). CONCLUSIONS: In this study, we have shown for the first time that indomethacin treatment can reduce levels of anxiety-like behavior and enhance levels of exploratory behavior in a neonatal rat model with HIE. It is necessary to determine whether nonsteroidal anti-inflammatory agents, such as indomethacin, should be used for adjuvant therapy in newborns with HIE.

Molecular characterization of goose parvovirus in geese of Turkey

ABSTRACT: Goose parvovirus (GPV), also called Derzsys disease, is a viral pathogen that causes high morbidity and mortality in goslings and ducklings. In this study, we perform the molecular characterization of the GPV in Turkey. The definition of similarity to the world of GPV isolates in Turkey and construction of a phylogenetic tree was aimed. For this purpose, the presence of GPV in the liver, spleen, and intestine tissues of nine goslings with symptoms such as dysphagia, bilateral ocular swelling, eye discharge, diarrhea, and fatigue were investigated by real-time PCR method and all samples were detected as positive. According to the data obtained by molecular characterization, phylogenetic analysis of GPV has been presented in Turkey. As a result of this study, it was determined that the GPVs available in Turkey are virulent strains.

RESUMO: O parvovírus do ganso (GPV), também chamado de doença de Derzsy, é um patógeno viral que causa alta morbidade e mortalidade em gansos e patinhos. Neste estudo, objetivou-se a determinação da caracterização molecular do GPV na Turquia, a definição da similaridade com o mundo dos isolados de GPV na Turquia e a construção de uma árvore filogenética. Para tanto, a presença de GPV no fígado, baço e tecidos do intestino de nove gansos com sintomas como disfagia, edema ocular bilateral, secreção ocular, diarreia e fadiga foram investigados pelo método de PCR em tempo real e todas as amostras foram detectadas tão positivo. À luz dos dados obtidos por caracterização molecular, a análise filogenética do GPV foi apresentada na Turquia. Como resultado deste estudo, foi determinado que os GPVs disponíveis na Turquia são cepas virulentas.
