These effects were significantly improved after treatment with NBHO. At the same time, NBHO significantly increased the expression levels of Nrf2 and HO-1 in the tissues after RIRI. To verify whether HO-1 induced by Nrf2 is involved in the resistance to oxidative stress, after the rat RIRI and before inhaling NBHO, we intraperitoneally injected HO-1 specific inhibitor zinc protoporphyrin (ZnPP) (45 μmol/Kg). However, we found that ZnPP reversed the protective effect of NBHO on RIRI in rats. Combining all the results, we have demonstrated the protective effect of NBHO on RIRI, which can be at least partially attributed to the activation of the Nrf2/HO-1 antioxidative stress pathway.Nucleotide-binding leucine-rich repeat-containing proteins, or NOD-like receptors (NLRs), are intracellular innate immune sensors that can regulate several signaling pathways, including MyD88- and TRIF-dependent pathways. In addition to these regulatory roles, some NLRs can assemble into multimeric protein complexes known as inflammasomes. NLRP12 is a member of the NLR family that contains an N-terminal pyrin domain, a central nucleotide-binding domain, and a C-terminal leucine-rich repeat. It has been shown to play a role in forming an inflammasome in response to specific infections, and it can also function as a regulator of inflammatory signaling. During Yersinia pestis or Plasmodium chabaudi infection, NLRP12 induces the release of the inflammasome-dependent cytokines IL-1β and IL-18. These NLRP12-dependent cytokines confer protection against severe infections caused by these pathogens. Conversely, during infection with Salmonella enterica serovar Typhimurium, vesicular stomatitis virus, Klebsiella pneumoniae, or Mycobacterium tuberculosis, and in colonic tumorigenesis, NLRP12 acts as a negative regulator of the NFκB and MAPK signaling pathways. NLRP12 also negatively regulates canonical and non-canonical signaling in T cells and causes exacerbated autoimmune diseases. Furthermore, NLRP12 acts as a central component in maintaining intestinal inflammation and gut homeostasis. Therefore, the ability of NLRP12 to function as an inflammasome or as a negative regulator is context-dependent. In this review, we provide an overview of the NLR family members and summarize recent insights into the roles of NLRP12 as an inflammasome and as a negative regulator.The spiked-helmet sign is a marker for high mortality in critical patients. It is characterised as a dome-shaped ST-segment elevation accompanied by an upward shift of the baseline before the onset of the QRS complex. We present two patients with the spiked-helmet sign on electrocardiogram. Patient A showed a potential relationship between the spiked-helmet sign and hyper-osmolar hyper-glycaemic state, whereas patient B had clinically suspected viral myocarditis.This article has been withdrawn at the request of the author(s) and/or editor.

Uncommonly encountered in general surgical and trauma practice, they remain extremely lethal despite advances in resuscitation and critical care. Important factors determining treatment outcomes are the hemodynamic status of the patient at presentation, the level and extent of injury, and the presence of associated injuries. Operative approaches and techniques for definitive repair are to be tailored to the condition of the patient, type of injury, and available expertise. In a patient with severe hemodynamic compromise, damage control principles take priority to stop bleeding and save life. The most commonly employed strategies are venorrhaphy or ligation. Retro-hepatic and supra-hepatic caval injuries are particularly challenging in terms of exposure and repair, and are associat
