Abstract
The COVID-19 pandemic has drawn attention to acute lung injury and respiratory distress syndrome as major causes of death, underscoring the urgent need for effective treatments. Protease enzymes possess a wide range of beneficial effects, including antioxidant, anti-inflammatory, antifibrotic, and fibrinolytic effects. This study aimed to evaluate the potential therapeutic effects of bacterial protease and chymotrypsin in rats in mitigating acute lung injury induced by lipopolysaccharide. Molecular docking was employed to investigate the inhibitory effect of bacterial protease and chymotrypsin on TLR-4, the receptor for lipopolysaccharide. Bacterial protease restored TLR-4, Nrf2, p38 MAPK, NF-kB, and IKK-β levels to normal levels, while chymotrypsin normalized TLR-4, IKK-β, IL-6, and IL-17 levels. The expression of TGF-β, caspase-3, and VEGF in the bacterial protease- and chymotrypsin-treated groups was markedly reduced. Our results suggest that both therapies ameliorate LPS-induced acute lung injury and modulate the TLR4/Nrf2/NF-k signaling pathway. Each protease exhibited distinct mechanisms, with bacterial protease showing a better response to oxidative stress, edema, and fibrosis, whereas chymotrypsin provided a better response in the acute phase and innate immunity. These findings highlight the potential of each protease as a promising therapeutic option for acute lung injury and respiratory distress syndrome.

Abstract
Thunbergia erecta L. contains cytotoxic and liver-protective compounds. Thunbergia erecta L. leaves were macerated in 70% aqueous ethanol, then fractionated with ethyl acetate (9.3 g) and butanol (12.7 g), and attenuated Den-induced liver cancer in a Wistar rat experimental model. Ethyl acetate and butanol fractions were chromatographed using column chromatography and solid-phase extraction (SPE); Vicenin-II (1), kaempferol (2), biochanin A, sissotrin 7-O-β-glucopyranoside (3), gentianose (4), acacetin 7-O-β-glucopyranoside (5), apigenin 7-O-β-glucopyranoside (6), and rosmarinic acid (7) were extracted, and their structures were determined using NMR spectroscopy and ESI-mass spectrometry. Sixty rats were divided into six groups (ten each): control group, Den group, doxorubicin/Den-treated group, butanol fraction/Den-treated group, and isolated acacetin 7-O-β-glucopyranoside/Den-treated group. The liver enzymes and proinflammatory biomarkers were used to estimate the liver function. In addition, liver tissues were collected for analysis of oxidative stress markers, gene expression, and histopathology. There is a significant increase in the levels of liver enzymes, AFP, and TNF-ἁ. This was conveyed by a significant increase of IL-1 and caspase-3, elevation of MDA and reduction of GSH, and suppression of Bcl2 and elevation of Bax expression. All parameters in butanol, ethyl acetate fractions, and isolated acacetin 7-O-β-glucopyranoside (major constituents) of T. erecta L. were significantly improved to values close to those of the control group.

Abstract
In chronic liver diseases, liver fibrosis occurs due to excessive extracellular matrix (ECM) protein accumulation. Approximately 2 million deaths occur yearly due to liver disease, while cirrhosis is the 11th most common cause of death. Therefore, newer compounds or biomolecules must be synthesized to treat chronic liver diseases. In this aspect, the present study focuses on the assessment of the anti-inflammatory and antioxidant impact of Bacterial Protease (BP) produced by a new mutant strain of bacteria (Bacillus cereus S6-3/UM90) and 4,4'-(2,5-dimethoxy-1,4-phenylene) bis (1-(3-ethoxy phenyl)-1H-1,2,3-triazole) (DPET) in the treatment of early stage of liver fibrosis induced by thioacetamide (TAA). Sixty male rats were divided into six groups, ten rats each as follows: (1) Control group, (2) BP group, (3) TAA group, (4) TAA-Silymarin (S) group, (5) TAA-BP group, and (6) TAA-DPET group. Liver fibrosis significantly elevated liver function ALT, AST, and ALP, as well as anti-inflammatory interleukin 6 (IL-6) and VEGF. The oxidative stress parameters (MDA, SOD, and NO) were significantly increased with a marked reduction in GSH. Expression of MAPK and MCP-1 was unregulated in the TAA group, with downregulation of Nrf2 was observed. TAA caused histopathological alterations associated with hepatic vacuolation and fibrosis, increasing collagen fibers and high immuno-expression of VEGF. On the other hand, treatment with BP successfully improved the severe effects of TAA on the liver and restored histological architecture. Our study concluded the protective potentials of BP for attenuating liver fibrosis and could be used as adjuvant therapy for treating hepatic fibrosis.

Abstract
BACKGROUND This study was conducted to assess the therapeutic effect of Myrrh on Diethylnitrosamine (DEN)-induced hepatocarcinogenesis (HCC) in male albino rats. METHODS Fifty male albino rats were divided into five groups (10 rats each). Group 1 (control group) received distilled water. Group 2 (positive control) was injected intraperitoneally with DEN (55 mg/kg b.w) twice a week for two weeks, while group 3 (DOX) received doxorubicin i.p (10 mg/ kg b.w) after concomitant with DEN twice a week for four weeks. Groups 4 and 5 received a low dose of Myrrh (250 mg/kg b.w) and a high dose of Myrrh (500 mg/kg b.w) respectively daily for four weeks after the induction with DEN. The sera were used to estimate the liver enzymes (ALT, AST, and ALP), Alpha-fetoprotein (AFP), Total antioxidant capacity (TAC), and Tumor necrosis factor-ἁ (TNF-ἁ). Also, the liver tissues were collected to determine the oxidative stress markers in addition to the histopathological and immunohistochemical investigations. RESULTS The results showed that the induction of DEN causes a significant increase in the level of liver enzymes (ALT, AST, and ALP), AFP and TNF-ἁ as well as produce oxidative stress indicated by increasing of malondialdehyde (MDA) with the reduction in TAC and glutathione (GSH). Meanwhile, there are noticeable histopathological lesions with loss of hepatic architecture. This was accompanied by a significant increase of immunohistochemical markers; Caspase-3, vascular endothelial growth factor (VEGF), transforming growth factor β1(TGF- β1), and carcinoembryonic antigen (CEA) percentage area. The treatment of DEN rats with DOX reduced the alterations in most parameters. A marked amelioration of all parameters in a dose-dependent manner of Myrrh to the values almost near to those of the control group. CONCLUSION Our data revealed that Water extract of Myrrh (C. molmol) has a potential therapeutic effect in attenuation of HCC induced DEN.

Abstract
Aluminum (Al) is an omnipresent mineral element in the environment. The brain is a central target of Al toxicity, being highly susceptible to oxidative damage. Therefore, recognition of drugs or natural products that guard against Al-mediated neuronal cell death is a powerful strategy for prevention and treatment of neurodegenerative disorders. This work aimed to explore the potential of a leaf extract from Harrisonia abyssinica to modulate the neurobehavioral, biochemical and histopathological activities induced experimentally by Al in vivo. Rats subjected to Al treatment displayed a reduction in learning and memory performance in a passive avoidance test accompanied by a decrease in the hippocampal monoamine and glutamate levels in addition to suppression of Bcl2 expression. Moreover, malondialdehyde (MDA), inflammatory markers (TNF-α, IL-1β), apoptotic markers (caspase-3 and expression of Bax) and extracellular regulated kinase (ERK1/2) levels were elevated along with acetylcholinesterase (AChE) activity, histological changes and marked deposition of amyloid β plaques in the hippocampus region of the brain tissues being observed in Al-treated animals. Concomitant administration of the high dose of H. abyssinica (200 mg/kg b.w.) restored nearly normal levels of all parameters measured, rather than the low dose (100 mg/kg b.w.), an effect that was comparable to the reference drug (rivastigmine). Molecular docking revealed the appropriate potential of the extract components to block the active site of AChE and ERK2. In conclusion, H. abyssinica leaf extract conferred neuroprotection against Al-induced neurotoxic effects, most likely due to its high phenolic and flavonoid content.

Abstract
Proximal tubule protein take-up is interceded by 2 receptors, megalin and cubilin. These receptors rescue an assortment of filtered ligands including fundamental vitamins and hormones. The objective of this study was to investigate the potential relation of megalin receptor injury with nuclear factor-kappa B (NF-κB) upregulation in acute kidney injury rat model. Twenty four rats were allocated into two groups: control group received saline, while the second group was intoxicated with cadmium chloride (2.4 mg Cd/kg/day i.p) for 30 days. Blood urea nitrogen, serum creatinine, tissue oxidant-antioxidant parameters (malondialdehyde [MDA] and reduced glutathione [GSH]) and expression levels for NF-κB, toll like receptor-2 (TLR2), toll like receptor-4 (TLR4), and megalin receptor were estimated. Noticeable downregulation of megalin receptor versus upregulation of NF-κB, TLR2, and TLR4 were observed in AKI rat model together with significant elevation in MDA as well as significant reduction in GSH. The study concluded that the oxidative stress in kidney tissue leads to megalin receptor damage, which indeed motivates upregulation of NF-κB through TLRs 2 and 4 pathways.
