[PMID: 38858704 PMCID: PMC11163697 DOI: 10.1186/s12906-024-04508-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2024] [Accepted: 05/21/2024] [Indexed: 06/12/2024] Open
Abstract
In the past few decades, there has been a notable rise in the occurrence of several types of candidiasis. Candida albicans is the most common cause of superficial fungal infections in humans. In this study, plumieride, one of the major iridoids from Plumeria obtusa L. leaves, was isolated and investigated for its potential against Candida albicans (CA)-induced dermatitis in mice. qRT-PCR was done to assess the impact of plumieride on the expression of the major virulence genes of CA. Five groups (n = 7) of adult male BALB/c mice were categorized into: group I: non-infected mice; group II: mice infected intradermally with 107-108 CFU/mL of CA; group III: CA-infected mice treated with standard fluconazole (50 mg/kg bwt.); group IV and V: CA-infected mice treated with plumieride (25- and 50 mg/kg. bwt., respectively). All the treatments were subcutaneously injected once a day for 3 days. Skin samples were collected on the 4th day post-inoculation to perform pathological, microbial, and molecular studies. The results of the in vitro study proved that plumieride has better antifungal activity than fluconazole, manifested by a wider zone of inhibition and a lower MIC. Plumieride also downregulated the expression of CA virulence genes (ALS1, Plb1, and Hyr1). CA-infected mice showed extensive dermatitis, confirmed by strong iNOS, TNF-α, IL-1β, and NF-κB genes or immune expressions. Whereas the treatment of CA-infected mice with plumieride significantly reduced the microscopic skin lesions and modulated the expression of all measured proinflammatory cytokines and inflammatory markers in a dose-dependent manner. Plumieride interfered with the expression of C. albicans virulence factors and modulated the inflammatory response in the skin of mice infected with CA.

Abstract
Nanotechnology offers excellent prospects for application in biology and medicine. It is used for detecting biological molecules, imaging, and as therapeutic agents. Due to nano-size (1-100 nm) and high surface-to-volume ratio, nanomaterials possess highly specific and distinct characteristics in the biological environment. Recently, the use of nanomaterials as sensors, theranostic, and drug delivery agents has become popular. The safety of these materials is being questioned because of their biological toxicity, such as inflammatory responses, cardiotoxicity, cytotoxicity, inhalation problems, etc., which can have a negative impact on the environment. This review paper focuses primarily on the toxicological effects of nanomaterials along with the mechanisms involved in cell interactions and the generation of reactive oxygen species by nanoparticles, which is the fundamental source of nanotoxicity. We also emphasize the greener synthesis of nanomaterials in biomedicine, as it is non-hazardous, feasible, and economical. The review articles shed light on the complexities of nanotoxicology in biosystems and the environment.

Abstract
Introduction Metal oxide nanoparticles are currently used widely in many aspects of human and animal life with broad prospects for biomedical purposes. The present work was carried out to investigate the effects of orally administrated TiO2NPs, ZnONPs, IONs and Al2O3NPs on the mRNA expression level of CYP 1A1 and NBN in the rat liver. Materials and Methods Four groups of male Albino rats were given their respective treatment orally for 60 days in a dose of 1/20 of the LD50 TiO2NPs (600 mg/Kg b.wt/day), ZnONPs (340 mg/Kg b.wt/day), IONs (200 mg/kg b.wt/day) and Al2O3NPs (100 mg/Kg b.wt/day) and a fifth group served as a control group. Rresults The mRNA level of CYP 1A1 and NBN showed up-regulation in all the NPs-treated groups relative to the control group. ZnONPs group recorded the highest expression level while the TiO2NPs group showed the lowest expression level transcript. Conclusion:The toxic effects produced by these nanoparticles were more pronounced in the case of zinc oxide, followed by aluminum oxide, iron oxide nanoparticles and titanium dioxide, respectively.

Abstract
Purpose: Riot control agents (RCAs) such as CS, CN, CR, PAVA, and OC, etc., are already in use and has produced numerous health risks, including skin burns, dermatitis, gastrointestinal issues, impairment of respiratory variables, conjunctivitis, etc., and even prolonged and repeated exposure may cause death. Therefore, there is a demand and need for non-lethal, non-toxic RCAs that can effectively control riots without resulting in fatal outcomes. This study was carried out to evaluate the health risks related to a novel formulation made from isolated Tragia involucrata leaf hair lining, that can be used as the best suitable non-lethal RCAs.Methods: According to the OECD guidelines, studies on acute dermal toxicity, dermal irritation/corrosion, and skin sensitisation were carried out. Wistar rats were used in an acute dermal toxicity study, and the results indicated no mortality, morbidity, or abnormal food-and-water intake, biochemical parameters, or histopathological examination findings. A study on dermal irritation in Rabbits produced moderate erythema and the effect was instantaneous and resolved within 72 hrs of post-exposure. A skin sensitisation test was conducted on Guinea pig.Results: The results showed that the formulation had moderate skin-sensitizing properties after the application of the challenge dose. Patchy erythema was seen, and it went away 30 hrs after the gauze patch was removed.Conclusion: The preclinical results did not produce any indication of severe toxicity which supports it to be used as a natural RCAs in the future.

Abstract
Numerous adverse effects on human health have been reported in epidemiological studies of oleoresin capsicum (OC) and other riot control agents (RCAs). Importantly, the daunting risk of such RCAs can be neutralized by optimizing the desired concentration of such agents for mob dispersal. Hence, a nonlethal riot control combinational formulation (NCF) was prepared for dispersing rioters without imparting fatal outcomes. However, for desired utilization of NCF, it is essential to recognize its extent of potential toxicity. Therefore, the current investigation evaluated the dermal toxicity of NCF using experimental animals in compliance with the OECD guidelines. Additionally, few essential metal ions were analyzed and found non -significantly different in the test rats as compared to control rats. Moreover, abnormal dermal morphology and lesions ultrastructural tissue defects were not noticed as evinced by different studies like ultrasonography, histology, and scanning electron microscopy (SEM) respectively. Further, Doppler ultrasonography exhibited non-significantly different blood flow velocity in both groups, whereas miles test demonstrated a significantly increased Evans blue concentration in test rats compared to the control rats, which might be due to an initial increase in blood flow via an instant action of the NCF at the cutaneous sensory nerve endings. However, our results demonstrated NCF can produce initial skin irritating and sensitizing effects in guinea pigs and rabbits without the antecedence of acute toxicity (≤2000 mg/kg) in Wistar rats.

Abstract
Zinc(Zn)-based materials have contributed greatly to the rapid advancements in tissue engineering. The qualities they possess that make them so beneficial include their excellent biodegradability, biocompatibility, anti-bacterial activity, among and several others. Biomedical materials that act as a foreign body, will inevitably cause host immune response when introduced to the human body. As the osteoimmunology develops, the immunomodulatory characteristics of biomaterials have become an appealing concept to improve implant-tissue interaction and tissue restoration. Recently, Zn-based materials have also displayed immunomodulatory functions, especially macrophage polarization states. It can promote the transformation of M1 macrophages into M2 macrophages to enhance the tissue regeneration and reconstruction. This review covers mainly Zn-based materials and their characteristics, including metallic Zn alloys and Zn ceramics. We highlight the current advancements in the type of immune responses, as well as the mechanisms, that are induced by Zn-based biomaterials, most importantly the regulation of innate immunity and the mechanism of promoting tissue regeneration. To this end, we discuss their applications in biomedicine, and conclude with an outlook on future research challenges.

Abstract
Cellulosic fiber (CF) in nanoform is emergingly finding its way for COVID-19 solution for instance via nanocomposite/nanoparticle from various abundant biopolymeric waste materials, which may not be widely commercialized when the pandemic strikes recently. The possibility is wide open but needs proper collection of knowledge and research data. Thus, this article firstly reviews CF produced from various lignocellulosic or biomass feedstocks' pretreatment methods in various nanoforms or nanocomposites, also serving together with metal oxide (MeO) antimicrobial agents having certain analytical reporting. CF-MeO hybrid product can be a great option for COVID-19 antimicrobial resistant environment to be proposed considering the long-established CF and MeO laboratory investigations. Secondly, a preliminary pH investigation of 7 to 12 on zinc oxide synthesis discussing on Fouriertransform infrared spectroscopy (FTIR) functional groups and scanning electron microscope (SEM) images are also presented, justifying the knowledge requirement for future stable nanocomposite formulation. In addition to that, recent precursors suitable for zinc oxide nanoparticle synthesis with emergingly prediction to serve as COVID-19 purposes via different products, aligning with CFs or nanocellulose for industrial applications are also reviewed.

Abstract
In recent decades there has been growing interest of material chemists in the successful development of functional materials for drug delivery, tissue engineering, imaging, diagnosis, theranostic, and other biomedical applications with advanced nanotechnology tools. The efficacy and safety of functional materials are determined by their pharmacological, toxicological, and immunogenic effects. It is essential to consider all degradation pathways of functional materials and to assess plausible intermediates and final products for quality control. This review provides a brief insight into chemical degradation mechanisms of functional materials like oxidation, photodegradation, and physical and enzymatic degradation. The intermediates and products of degradation were confirmed with analytical methods such as proton nuclear magnetic resonance (1H NMR), gel permeation chromatography (GPC), UV-vis spectroscopy (UV-vis), infrared spectroscopy (IR), differential scanning calorimetry (DSC), mass spectroscopy, and other sophisticated analytical methods. These analytical methods are also used for regulatory, quality control, and stability purposes in industry. The assessment of degradation is important to predetermine the behavior of functional materials in specific storage conditions and can be relevant to their behavior during in vivo applications. Another important aspect is the evaluation of the toxicity of functional materials. Toxicity can be accessed with various methods using in vitro, in vivo, ex vivo, and in silico models. In vitro cell culture methods are used to determine mitochondrial damage, reactive oxygen species, stress responses, and cellular toxicity. In vitro cellular toxicity can be measured by MTT assay, LDH leakage assay, and hemolysis. In vivo studies are performed using various animal models involving zebrafish, rodents (mice and rats), and nonhuman primates. Ex vivo studies are also used for efficacy and toxicity determinations of functional materials like ex vivo potency assay and precision-cut liver slice (PCLS) models. The in silico tools with computational simulations like quantitative structure-activity relationships (QSAR), pharmacokinetics (PK) and pharmacodynamics (PD), dose and time response, and quantitative cationic-activity relationships ((Q)CARs) are used for prediction of the toxicity of functional materials. In this review, we studied the principle methods used for degradation studies, different degradation pathways, and mechanisms of functional material degradation with prototype examples. We discuss toxicity assessments with different toxicity approaches used for estimation of the safety and efficacy of functional materials.

Abstract
Carbendazim (CBZ) contamination of food and water is a principal factor in many negative impacts on public health. Nanoencapsulation of agrochemicals by nontoxic polymers as chitosan nanoparticles (CS-NPs) is one of the most applications of nanotechnology in agriculture. Despite its many advantages, such as it provides controlled release property, more stability and solubility of the active ingredient, it is not authorized to be used in the market because there are no adequate studies on the nano pesticides induced toxicity on experimental animals. So, we aim to study the possible impacts of CBZ-loading CS-NPs on the whole brain of rats and to explain its mechanism of action. 20 male Wistar rats were partitioned into 4 groups as follows: Group (1), normal saline; group (2), 5 mg/kg CS-NPs; group (3), 300 mg/kg CBZ; group (4) 300 mg/kg CS/CBZ-NCs. After 28 days, some neurobehavioral parameters were assessed to all rats then euthanization was done to collect the brain. Our results revealed that CBZ prompted neurotoxicity manifested by severe neurobehavioral changes and a significant increase of MDA with a decrease of GSH and CAT in brain tissue. In addition, there were severe neuropathological alterations confirmed by immunohistochemistry which showed strong bax, GFAP, and TNF-ὰ protein expression in some brain areas. CBZ also induced apoptosis manifested by up-regulation of JNK and P53 with down-regulation of Bcl-2 in brain tissue. Otherwise, encapsulation of CBZ with CS-NPs could reduce CBZ-induced neurotoxicity and improve all studied toxicological parameters. We recommend using CBZ-loading CS-NPs as an alternative approach for fungicide application in agricultural and veterinary practices but further studies are needed to ensure its safety on other organs.

Abstract
Silver nanoparticles (Ag-NPs), silver oxide nanoparticles (AgO-NPs), and zinc oxide nanoparticles (ZnO-NPs) have healing, antibacterial, and antioxidant properties. Furthermore, Ag-NPs and ZnO-NPs also have anti-inflammatory properties. In this study, we synthesized a nanocomposite using Ag-ZnO and AgO-NPs (Ag-ZnO/AgO NPs). The structural and morphological properties of nanocrystals and nanocomposite were investigated by X-ray diffraction and scanning electronics microscopic. The wurtzite crystalline structure of Ag-ZnO and two morphologies for the nanocomposite (nanorods and nanoplatelets) were determined. Topical treatment with 1% Ag-ZnO/AgO NPs was compared to untreated wounds (control group). Wounds were induced in the dorsal region of BALB/c mice and evaluated after 3, 7, 14, and 21 days of treatment. The nanocomposite demonstrated anti-inflammatory and antioxidant capacities. In addition, wounds treated with Ag-ZnO/AgO NPs showed accelerated closure, non-cytotoxicity, especially on keratinocytes and collagen deposition, and increased metalloproteinases 2 and 9 activity. The nanocomposite improved healing by reducing the inflammatory process, protecting tissues from damage caused by free radicals, and increasing collagen deposition in the extracellular matrix. These characteristics contributed to the accelerated wound closure process. Thus, Ag-ZnO/AgO NPs show potential for can be a strategy for topical use in formulations of new drugs to treat wounds.

Abstract
Copper oxide nanoparticles (CuO-NPs) are consciously used to control the growth of bacteria, fungi, and algae. Several studies documented the beneficial and hazardous effects of CuO-NPs on human cells and different experimental animals but there are not many studies that report the effect of CuO-NPs in poultry. Therefore, the present study was performed to investigate the dose-dependent effects of copper oxide nanoparticles on the growth performance, immune status, oxidant/antioxidant capacity, DNA status, and histological structures of most edible parts of broiler chickens (muscle, heart, liver, spleen, and kidneys). The experiment was carried out on 90 1-day-old broiler chicks (Cobb 500) which were divided into three experimental groups (n = 30) in three replicates (n = 10). Group 1 was kept as a control group and did not receive copper oxide nanoparticles. Groups 2 and 3 received CuO-NPs by oral gavage at dose 5 mg/kg and 15 mg/kg bwt respectively at 1, 7, 14, 21, 28, and 35 days of the life of the chickens. An increase in the amount of feed intake and weight was recorded every week, and finally, the food conversion ratio (FCR) was calculated. Our results showed dose-dependent increases in malondialdehyde levels, copper contents, DNA fragmentation percent, and microscopic scoring in different examined organs of CuO-NPs-receiving groups associated with a remarkable reduction in weight gain, food conversion ratio, catalase activity, and antibody titer of both New Castle and Avian Influenza viruses. Histopathological alterations were observed in both groups receiving CuO-NPs with some variations in its severity. Our study concluded that CuO-NPs are considered cytotoxic and we recommend not adding them to poultry feed.

Abstract
Lead is one of the major environmental pollutions worldwide, particularly in developing countries. Though, various occupational and public health measures have been undertaken to control lead exposure. The present study is designed to investigate the role of zinc oxide nanoparticles (ZnO-NPs) to reduce the bioaggregation of lead in the brain, liver, and kidneys and prevent these organ oxidative damage and apoptosis. Twenty male Wistar rats were grouped into 4 gatherings and exposed to the following materials daily on the skin for 2 weeks: 1-normal saline, 2-ZnO-NPs, 3-PbO, and 4-ZnO-NPs+ PbO. Topical application of PbO to rats increased lead contents in blood and different organs causing remarkable oxidative stress damage, apoptosis, and histopathological alterations in these organs. Moreover, PbO-receiving group showed strong positive caspase-3 protein expression with up-regulation of mRNA levels of BAX and COX-2. Co-treatment of ZnO-NPs with PbO could diminish the toxicologic parameters and the above-mentioned immune marker and gene expression levels. Our data suggest the role of ZnO-NPs cream to reduce the risk of lead dermal exposure via preventing absorption and accumulation of it in the internal organs so that it protects these organs from further damage.

Abstract
Copper oxide nanoparticles (CuO-NPs) are extensively utilized in several industries and in pharmaceutical production. This excess exposure elevates the concern about its expected poisonous impacts on humans and animals. Pomegranate juice (PJ) is a natural source of polyphenols and exhibits potent antioxidant activities. Our experiment intended to explore the neurobehavioral and toxicopathological impacts of CuO-NPs and to explain the mechanistic role of PJ to reduce their toxicity. Thirty Wistar albino rats received the subsequent materials through oral gavage, every day for 28d: (1) normal saline, (2) 3 mL/kg bwt PJ, (3) 6 mL/kg bwt PJ, (4) 300 mg/kg bwt CuO-NPs, (5) CuO-NPs + 3 mL/kg bwt PJ, (6) CuO-NPs + 6 mL/kg bwt PJ. Continuous exposure to CuO-NPs caused a significant elevation of MDA levels and reduction of total antioxidant capacity associated with remarkable pathological alterations in all brain regions including cerebrum, hippocampus and cerebellum. Progressive decline of memory along with cognitive and psychiatric disturbances were observed in rats exposed to CuO-NPs not in PJ co-treated rats. Continuous exposure to CuO-NPs caused over expression of the immunohistochemical markers of caspase-3, iNOS and GFAP altogether with DAN fragmentation and down-regulation of HO-1 and Nrf2 gene in the whole brain tissues. Conversely, rats co-treated with PJ showed dose dependent improvements in the entire toxicological, behavioral, and pathological parameters. We showed that PJ had the ability to reduce the oxidative stress damage via up-regulation of HO-1 and Nrf2 genes in the brain. So that PJ had the ability to protect the brain and DNA from further damage.

Abstract
To solve the damage to the environment and human body caused by organic solvent adhesives in the utilization process, chitin nanocrystal (ChNC) suspension is explored as a strong anisotropic adhesive, which is an eco-friendly and water-based adhesive with high adhesive strength. ChNCs extracted from crab shells are rod-like nanoparticles with high aspect ratios, which are mainly employed as reinforcing polymer nanocomposites and biomedicine nanomaterials. ChNC suspension sandwiched between substrates forms a long-range ordered superstructure by a self-assembly process. ChNC nanoglue exhibits high anisotropy adhesion strength, i.e., an in-plane shear strength (5.26 MPa) and an out-of-plane shear strength (0.46 MPa) for glass substrates. Moreover, the ChNC nanoglue is suitable to many substrates, such as glass, plastic, wood, metal, paper, etc. The ChNC nanoglue shows high biocompatibility toward the fibroblast cell and rat skin, proving their excellent biosafety. As an eco-friendly and high-performance adhesive, ChNC nanoglue shows promising applications in daily life and industrial fields.

Abstract
Cisplatin is a highly cytotoxic anticarcinogenic drug used to treat several kinds of solid tumors such as liver tumors. With the increase in the incidences associated with hepatic tumors and a lack of selectivity of cisplatin to cancer cells, it is important to explore new therapeutic strategies against them. The present study was designed to verify the ability of gold nanoparticles (GNPs) to improve the hepatotherapeutic effect of cisplatin against DENA-induced hepatic tumors and to declare its ability to reduce the renal toxicity induced by cisplatin. Forty male Wistar rats were divided into two groups (n = 20): Group (A)-negative control and group (B)-model of hepatocellular tumor induction. After 4 months, each group was subdivided into four subgroups as the following: Group (1) received normal saline, Group (2) was treated by cisplatin, Group (3) was treated by GNPs, Group (4) was treated by GNPs-cisplatin conjugates. Our results revealed a marked elevation in liver and kidney function tests and oxidant levels with a reduction in antioxidant levels in the DENA-administrated group. Remarkable histopathological alterations in the liver and kidney tissue sections were observed and confirmed by the overexpression of the immunohistochemical staining of placental glutathione S-transferase, Hep Par 1, and proliferating cell nuclear antigen. Noticeable improvements in all the measurable toxicological parameters were recorded in the group treated with either GNPs or GNPs-cisplatin conjugate not observed in the group treated with cisplatin. We can conclude that GNPs not only improve the distribution of cisplatin, targeting it to the site of tumors, but it also reduces the renal toxicity induced by cisplatin, which are the primary concerns in cancer therapy.

Abstract
Methicillin-resistant Staphylococcus aureus (MRSA) is one of the most threatening multidrug-resistant bacteria worldwide. Owing to their efficient antimicrobial properties, nanoparticles have been widely used as an alternative approach for combating the antibiotic-resistant bacteria. Consequently, this study was designed to compare in between the bactericidal effect of low doses (5 mg/kg bwt) of nanoparticles of chitosan (Ch-NPs), silver (Ag-NPs), and chitosan-silver nanocomposites (Ch-Ag NCs) both in vitro and in vivo against experimentally chronic infection induced by methicillin-resistant Staphylococcus aureus (MRSA). The three forms of nanoparticles were tested for their in vitro antimicrobial potential against MRSA by detection of MICs and MBCs using microdilution method. In vivo, thirty-five male albino Wistar rats were used and divided into five groups (n = 7). Group l (negative control), group 2 (MRSA infected and untreated), groups 3, 4, and 5 (MRSA infected then treated with Ch-NPs, Ag-NPs, and Ch-Ag NCs respectively for 7 days). After 6 weeks, blood samples were collected then rats were euthanized to collect different organs (liver, spleen, lungs, and kidneys). Some of them were kept in 10% formalin for histopathological investigations while others used for bacterial re-isolation. Ch-Ag NCs showed the lowest MIC and MBC among the tested nanoparticles. Moreover, the highest histopathological scoring was observed in the infected and untreated group while the lowest scoring was detected in groups treated with Ch-Ag NCs in comparison with the negative control group. The highest bacterial count was noticed in the infected and untreated group followed by those treated with Ch-NPs while the lowest count was observed in group treated with Ch-Ag NCs. Depending on these results, it can be concluded that Ch-Ag NCs have a strong bactericidal effect against MRSA and may be used as alternative option to antibiotics.

Abstract
The present study was led to investigate the defensive role of Terminalia laxiflora extract (TLE) on fipronil (FPN) induced hepatotoxicity and nephrotoxicity in male rats. Rats were administered with TLE (100 mg/kg) against the renal toxicity and hepatotoxicity induced by administration of FPN (10.5 mg/kg) for 30 days. At the end of the experimental period, the serum, liver, and kidneys were harvested and assessed for subsequent analysis. FPN administration to rats resulted in a significant elevation of serum transaminases, urea, and creatinine. Also, FPN-treated groups exhibited a marked reduction in total protein and albumin levels. Compared with the control group, the level of malondialdehyde (MDA) was elevated in groups treated with FPN, whereas superoxide dismutase (SOD), catalase (CAT) activities, and glutathione levels were distinctly reduced in this group. Significant increases in genomic DNA fragmentation and the expression level of the caspase-3 gene were also recorded. The biochemical result was supported by histopathological findings. Co-administration of TLE along with FPN significantly diminished the liver and kidney function tests decreased the level of lipid peroxidation, and enhanced all the antioxidant enzymes, while also diminishing the expression of caspase-3 and DNA laddering, indicating amelioration of DNA damage. These results indicate that TLE plays a vital role in diminishing FPN-induced hepatotoxicity and nephrotoxicity.

Abstract
Hexavelant chromium (Cr (V1)) is a widely distributed environmental pollutant inducing damage in different organs of human and animals. The current study was designed to investigate the mechanistic role of rosmarinic acid (RA) to diminish chromium-induced hepatorenal oxidative damage and preneoplastic lesions in rats. Plant material was collected, identified, and extracted. The isolated RA was elucidated relying on the nuclear magnetic resonance spectroscopic data. Twenty-eight male Wistar rats received the following materials daily via oral gavage for 60 days; (Gp1): normal saline, (Gp2) 25 mg/kg.bwt RA, (Gp3) 10 mg/kg.bwt potassium dichromate (K2 Cr2 O7 ), (Gp4) K2 Cr2 O7 + RA. All rats were euthanized at the end of the experiment by cervical dislocation and the liver and kidney were collected. Prolonged continuous exposure of rats to chromium-induced oxidant/antioxidant imbalance manifested by significant elevation of malondialdehyde with reduction in reduced glutathione levels. Remarkable histopathological alterations in the liver and kidney tissue sections were recorded and confirmed by overexpression of the immunohistochemical staining of caspase-3, placental glutathione-S transferase, proliferating cell nuclear antigen together with a significant downregulation of nuclear factor erythroid-2 related factor 2 (Nrf2) gene and upregulation of nibrin gene. Observable improvements in the entire toxicopathological parameters were recorded in group cotreated with RA. Our findings revealed that Cr-induced preneoplastic lesions on the liver and kidney tissues of rats when exposed daily for long period of time, as well as confirmed the ability of RA to alleviate this toxicity through upregulation of Nrf2 pathway and its powerful antioxidant effects.

Abstract
The laser pretreatment of seed is drawing pronounced attention from the scientific community for its positive impact in boosting germination, seedling , and growth of plants. In this study, the laser pretreatment of Adansonia digitata (A. digitata) seeds was evaluated. Eight laser treatments were conducted at different powers, 10, 20, 40, and 80 mW, with the two-time interval for each power at 2 and 4 min. The outcomes indicated that the most efficient irradiation was 10 mW/2 min which induces the highest germination rate and polyphenolic contents for seeds. Based on these results, the animal experimental design was processed to assess the hepatoprotective activity of A. digitata extracts obtained through the optimum laser preillumination to enhance the resistance of liver damage in mice. The total phenol and flavonoid contents and the antioxidant properties of the methanolic extracts were estimated in vitro. The CCl4 was used to induce hepatotoxicity in mice. The animals were divided into five groups. The sera of the treated animals were used for the determination of transaminases, and the liver homogenates were used for the determination of antioxidant status, and further liver tissues were subjected to verify the anti-apoptotic effect of A. digitata methanolic extract. The in vivo results showed that the methanolic extract exposed to laser treatment at 10 mW/2 min provided better hepatoprotective capacity than the other treatments. Administration of A. digitata extract not only offered a significant decrease in liver enzyme activity but also markedly improved the antioxidant status and reduced the apoptotic progression induced by CCl4 toxicity in liver tissue.

Abstract
The present study aimed to evaluate what dosage of gold nanoparticles (GNPs) would improve growth performance, antioxidant levels and immune defense in broiler chickens. The experiment was carried out on 90 one-day-old mixbred Cobb chicks. The birds were allocated into three groups with three replicates. Group (1) kept as a negative control. Groups (2) and (3) received 5, 15 ppm GNPs via drinking water weekly for 35 days of chicks' life. Blood samples were collected at 8, 15, 22 and 36 days for oxidative stress evaluations and immunological studies. The birds were slaughtered at the ages of 36 days and thymus, spleen, busa of Fabricius and liver were collected for histopathological description, RT-PCR analysis and DNA fragmentation assay. Our results confirmed that adding of 15ppm GNPs in drinking water were induced remarkable blood oxidative stress damage, histopathological alterations, up-regulation of IL-6, Nrf2 gene expression, and DNA fragmentation in the examined immune organs of the broiler chickens as well as a significant reduction in the antibody titer against Newcastle (ND) and avian influenza (AI) viruses were noticed. On the other hand, the group received 5 ppm GNPs noticed better growth performance with the enhancement of the final food conversion ratio (FCR) without any significant difference in the previous toxicological and immunological parameters compared with the control groups. We suggest that feeding of 5ppm GNPs could improve the antioxidant capacity, immunity and performance in poultry but further food quality assurance tests are required in the future to confirm its safety for people.
