Adverse events associated with IL-23 and IL-12/23 inhibitors in the clinical management of psoriasis: a comprehensive pharmacovigilance analysis
Interleukin-23 (IL-23) inhibitors and the IL-12/23 inhibitor ustekinumab constitute a pivotal class of therapeutic agents employed in the clinical management of Psoriasis, a chronic immune-mediated skin disorder. Notwithstanding their therapeutic efficacy, concerns have arisen due to the emergence of multiple adverse events (AEs) associated with their usage. This study aims to provide a comprehensive examination of the distribution and characteristics of these AEs concerning IL-23 and IL-12/23 inhibitors, with a specific focus on guselkumab, tildrakizumab, risankizumab, and ustekinumab.
Conditioned medium from human adipose-derived mesenchymal stem cells attenuates cardiac injury induced by Movento in male rats: role of oxidative stress and inflammation
Movento an insecticide containing spirotetramat, has been shown to cause severe toxicity in humans and rats. Due to the widespread use of the Movento in agriculture, and since the cardiac effects of this toxin have not been investigated in any study so far, in this study, for the first time, the effect of movento on the structure and function of the heart in rats was investigated. 24 adults' male Wistar rats randomly divided to 4 experimental groups: 1- control (CTL), 2- Movento (M) 3- M + Basal media (BM) 4- M + Conditioned medium (CM). Animals were subjected to deep anesthesia to record the ECG and blood pressure. H&E staining was performed to determine the degree of damage. Oxidative stress markers and inflammatory factors were investigated with related kits. In rats that received Movento's insecticide, mean arterial pressure (MAP), amplitude of the P wave and total antioxidant capacity (TAC) decreased compared to the control group and treatment with CM increased them significantly compared to M and M + BM group. Also, Movento increased histological score, MDA, TNF-α and IL-6 compared to the control group and CM significantly decreased them compared to M and M + BM groups. CM derived from mesenchymal stem cells (MSC) can be used as a therapy for heart disorders caused by movento toxin in the heart of rats. Also, it seems that this treatment could be a promising way to improve heart complications in farmers exposed to this toxin in the future.

Boswellic acid synergizes with low-dose ionizing radiation to mitigate thioacetamide-induced hepatic encephalopathy in rats
Hepatic encephalopathy (HE) is a syndrome that arises from acute or chronic liver failure. This study was devised to assess the impact of a combination of boswellic acid (BA) and low doses of gamma radiation (LDR) on thioacetamide (TAA)-induced HE in an animal model. The effect of daily BA treatment (175 mg/kg body weight, for four weeks) and/or fractionated low-dose γ-radiation (LDR; 0.25 Gy, twice the total dose of 0.5 Gy) was evaluated against TAA (200 mg/kg, intraperitoneal) twice-weekly for four weeks to induce liver damage and HE in rats. TAA-exposed rats exhibited a significant elevation in serum activities of liver enzymes (GGT, ALP) and plasma ammonia levels at P < 0.05 (Duncan's test) compared to the control group. Moreover, there was an increase in the levels of proinflammatory cytokines (IL6, IL12, IL18) in the TAA-exposed animals accompanied by a depletion in the activities of paraoxonase-1 and neurotransmitter contents compared with normal control rats (P < 0.05). However, the administration of BA alone or in combination with LDR led to improvements in liver and brain parameter indices. Furthermore, the histopathological assessments of liver and brain tissues supported the findings of the biochemical investigations. From the statistical analysis, it can be concluded that the combined administration of BA and exposure to LDR may possess potential hepatoprotective effects against hepatic encephalopathy-associated hyperammonemia and the consequent damage to the liver and brain. This study proposes that a combination of therapeutic approaches, LDR and BA could be a new therapeutic candidate for the management of hepatic encephalopathy.
Systematic review and meta-analysis on the carbapenem-resistant hypervirulent Klebsiella pneumoniae isolates
The global dissemination of carbapenem-resistant hypervirulent Klebsiella pneumoniae (CR-hvKp) poses a critical threat to public health.

Alzheimer's disease: an integrative bioinformatics and machine learning analysis reveals glutamine metabolism-associated gene biomarkers
Alzheimer's disease (AD), a hallmark of age-related cognitive decline, is defined by its unique neuropathology. Metabolic dysregulation, particularly involving glutamine (Gln) metabolism, has emerged as a critical but underexplored aspect of AD pathophysiology, representing a significant gap in our current understanding of the disease.
Potential antihyperlipidemic effects of myrcenol and curzerene in high-fat fed rats
The study evaluated the anti-hyperlipidemic effects of myrcenol and curzerene on a high fat diet induced hyperlipidemia rat model. Thirty male albino rats were fed on a high-fat diet for four months. The HFD-induced hyperperlipidemia rats were treated with rosuvastatin (10 mg/kg), curzerene (130 mg/kg) and myrcenol (100 mg/kg) for four weeks. Blood samples were collected for further analysis. Aorta and heart were harvested for histopathological evaluation. Hepatic lipase and HMG-CoA reductase were determined by ELISA. FST and Y-maze tests were performed to assess the stress level in hyperlipidemia rats. The phytochemical compounds (Curzerene and Myrcenol) and the standard drug (Rosuvastatin) resulted in decreased body weight as well as reduced levels of LDL, TG, TC, AST and ALT as compared to the diseased group. Additionally, the treated groups displayed improved HDL levels and less depressed behavior. The ELISA results revealed that the Curzerene and myrcenol had significantly increased the protein concentration of hepatic lipase than the diseased group whereas both compounds significantly lowered the HMG-CoA reductase concentrations compared to the diseased group. The findings suggested that myrcenol and curzerene had the potential to be therapeutic agents for managing hyperlipidemia and reducing the risk of heart-related conditions associated with high lipid levels.

Characterization and interactions between piperine and ezetimibe in their Anti-hyperlipidemic efficacy using Biopharmaceutics and Pharmacokinetics
Piperine, a secondary metabolite, affects the antihyperlipidemic effect of Ezetimibe (EZ). Hyperlipidemia is one of the independent risk factors for cardiovascular disorders such as atherosclerosis. Antihyperlipidemic drugs are essential for reducing cardiovascular events and patient mortality. Our study aimed to improve the solubility of EZ, a lipid-lowering drug that belongs to BCS II and has low solubility. Piperine, a bioenhancer, can increase the bioavailability of other pharmaceuticals without modifying their fundamental characteristics or enhancing their efficacy. The objective of this study was to increase the bioavailability of EZ while also improving its potency and reducing its toxicity by using piperine as a bioenhancer. Therefore, rats were given piperine combined with EZ, and their antihyperlipidemic activity was assessed while fed a high-fat diet.
