“…Histological analysis of the liver of tilapia fish allowed the identification of both free and grouped melanomacrophages, mainly near blood vessels as shown in figure 2A. The primary functions of MMCs involve the destruction, detoxification, and recycling of foreign materials within the body [15]. Particularly, the presence of melanomacrophage centers in fish liver is indicative of environmental conditions, as these centers play a role in the biotransformation of xenobiotic substances [16].…”

Copper and zinc are needed as essential nutrients for plants, animals, and human’s daily basic activity, however, at high concentrations and prolonged exposure they bring harmful effect to life creature and the environment. Thus, this study aimed at finding out the toxicological impact of copper and zinc on liver and gill tissues of Oreochromis mossambicus. This study used 21 male tilapia (60-100 grams), which grouped into 7 treatment groups, K1 was negative control; K2, K3, and K4 were exposed to 1, 2.5, and 5 mg/L CuSO4; K5, K6, and K7 were exposed to 2.5, 5, and 7.5 mg/L ZnCl2, respectively, for 15 days. Fish liver and gill were collected for histopathological procedure using hematoxylin-eosin. The results showed similar figure of tissues damages between treatment groups, including melanomacrophage center, vacuolar degeneration, cell necrosis, and hemorrhage. The spreading of MMCs in the liver tissue of tilapia fish exposed to copper was higher than in zinc exposure. In gills tissue, several minor, moderate, and severe changes were observed, revealed that the higher the concentration of CuSO4 and ZnCl2 exposure the more severe the tissue damage observed. In conclusion, both CuSO4 and ZnCl2 exposure changes the histopathology of liver and gill of tilapia fish.

“…Large variations in the incidence of accessory fissures on the diaphragmatic surface of the liver have been reported, ranging from 2% (Saritha et al, 2015) to 63% (Auh et al, 1984). The notice-able discrepancy in incidence could be attributed to factors that may lead to the formation of these accessory hepatic indentations on the weaker regions of the liver, for example pressure from the ribs or the diaphragmatic muscle (Reddy et al, 2016). An understanding of these indentations and their causes may be of significance in the precise diagnosis and interpretation of sonography and/or CT imaging (Auh et al, 1984), as these indentations may be confused with hepatic cysts or haematomae.…”

Bisphenol A (BPA) is an environmental pollutant that harms different body systems. Previous investigations indicated that BPA exposure is linked to renal dysfunction. Among carotenoids, lycopene (Lyc) is one of the strongest antioxidants. This work was conducted to assess the potential protective benefits of Lyc on oxidative stress and biochemical and histological abnormalities induced by BPA in the kidney. Adult male rats were divided into: control group, Lyc group (4 mg/kg /day), BPA group (50 mg/kg/day), and Lyc-BPA group. The agents were given orally for eight weeks. BPA induced a marked increment in malondialdehyde (MDA) and a marked decrement in the superoxide dismutase (SOD) level. A marked rise in creatinine and urea levels was also reported. Marked histopathological alterations were demonstrated in the renal cortex. Atrophy of the renal corpuscles, dilated tubules with degenerated epithelium, dilated congested cortical renal blood vessels, and cellular infiltration were demonstrated. Up-regulation of the immune expression of desmin and down-regulation of Bcl2 were also detected. Interestingly, co-administration of Lyc and BPA ameliorated to a great extent most of the biochemical and histopathological alterations induced by BPA. In conclusion, BPA had a harmful impact on the kidney of rats and Lyc protected against renal damage through its antioxidant, anti-inflammatory, and anti-apoptotic effects.

“…Similar works on safe strategies include the use of accumulated past knowledge [5], making conservative action choices that prioritize avoiding the worst-case scenario. Other works, such as [6], [7], request guidance from a human operator or an external agent when the operating state is considered risky.…”

The success of Software-Defined Networking and Network Function Virtualization enabled providers to partially automate the decision-making of various network operating workflows. Network slicing is an innate feature of the Fifth Generation (5G) and Beyond-5G (B5G) networks, bringing many advantages but also increasing the complexity of managing such networks. In this context, automation tools based on Artificial Intelligence (AI) have become a preeminent instrument of automation used by the industry, as it would be impossible to manually provision and manage such a vast and dynamic infrastructure. Safe interaction of the AI agents with the network is one of the predominant challenges, especially when Reinforcement Learning (RL) is used in critical environments. This is particularly important when the RL agent actions have a high or irreversible impact on the network or service. Slice management is one of the major features that operators want to automate, to offer future services at large scales with manageable complexity to the operator. However, during the exploration phase, RL agents can cause significant performance degradation during operation and possibly introduce irreversible damage to the service being offered. To address this major challenge, we propose a multi-agent, modular, SafeRL architecture for distributed slice orchestration. We study the problem of zerotouch slice management and orchestration, in the context of Ultra-Reliable Low Latency Communication services for B5G networks. Our results demonstrate improved performance over competing solutions, while ensuring the safety of the performed actions during real-time slice orchestration.
