Objectives: Sodium arsenite (SA) exposure is toxic to the body. Zingerone (ZNG) is a flavonoid with many biological properties found naturally in honey and plants. This study aimed to determine the effects of ZNG on SA-induced rat lung toxicity.
Materials And Methods: Thirty-five male Sprague rats were divided into Control, SA, ZNG, SA+ZNG25, and SA+ZNG50 groups (n=7). SA 10 mg/kg and ZNG were administered at two doses (25 and 50 mg/kg) (orally, 14 days). Analysis of oxidative stress, inflammation damage, apoptosis damage, and autophagic damage markers in lung tissue were determined by biochemical and histological methods.
Results: The administration of ZNG reduced oxidative stress by increasing SA-induced decreased antioxidant enzyme activities, increasing Nrf-2, HO-1, and NQO1, and decreasing MDA level. ZNG administration reduced inflammation marker levels. Anti-apoptotic Bcl-2 increased and apoptotic Bax and Caspase-3 decreased with ZNG. ZNG promoted the regression of autophagy by reducing Beclin-1, LC3A, and LC3B levels.
Conclusion: Evaluating all data showed that SA caused toxic damage to lung tissue by increasing inflammation, apoptosis, autophagy, and oxidant levels, whereas ZNG had a protective effect by reducing this damage.

Background: Approximately half of the patients with acute ischemic stroke who receive intravenous thrombolysis (IVT) do not achieve an excellent outcome. Remote ischemic conditioning (RIC) as a promising neuroprotective treatment may improve clinical outcomes in this population. This study aimed to assess the efficacy and safety of RIC in patients with IVT.

We consider the zero-dimensional quartic () vector model and present a complete study of the partition function (, ) and its logarithm, the free energy (, ), seen as functions of the coupling on a Riemann surface. We are, in particular, interested in the study of the transseries expansions of these quantities. The point of this paper is to recover such results using constructive field theory techniques with the aim to use them in the future for a rigorous analysis of resurgence in genuine quantum field theoretical models in higher dimensions.

Article Synopsis
- Arsenic exposure is linked to diabetes and liver toxicity, and Zingerone (ZNG) from ginger shows potential protective effects against these issues.
- ZNG was administered to male mice prior to arsenic treatment, and results indicated that it helped lower fasting blood glucose levels, improved glucose tolerance, and reduced liver damage caused by arsenic.
- The study concludes that ZNG has protective properties that potentially mitigate the harmful effects of arsenic on the liver and overall glucose metabolism.

Article Synopsis
- Copper is essential for living organisms, but its excess can cause diseases like Wilson's disease, which often results in liver and brain issues.
- Current treatments like penicillamine and zinc gluconate have limitations, prompting research into melatonin's potential as a therapy.
- In studies on rats, melatonin and its combinations with other treatments showed significant improvements in behavior, pathology, and copper levels, while also influencing key metabolic pathways and gene expressions.
