Melatonin may reduce NLRP3 inflammasome activation by inhibiting oxidative stress and thus protect against injury from AFB1-induced myocardial toxicity. Melatonin may reduce NLRP3 inflammasome activation by inhibiting oxidative stress and thus protect against injury from AFB1-induced myocardial toxicity. Lethal stressors, including antimicrobials, kill bacteria in part through a metabolic response proposed to involve reactive oxygen species (ROS). The quinolone anti-bacterials have served as key experimental tools in developing this idea. Bacteriostatic and bactericidal action of quinolones are distinguished, with emphasis on the contribution of chromosome fragmentation and ROS accumulation to bacterial death. Action of non-quinolone antibacterials and non-antimicrobial stressors is described to provide a general framework for understanding stress-mediated, bacterial death. Quinolones trap topoisomerases on DNA in reversible complexes that block DNA replication and bacterial growth. At elevated drug concentrations, DNA ends are released from topoisomerase-mediated constraint, leading to the idea that death arises from chromosome fragmentation. However, DNA ends also stimulate repair, which is energetically expensive. An incompletely understood metabolic shift occurs, and ROS accumulate. Even after quinopair of ROS-oxidized nucleotides. Remarkably, perturbations that interfere with ROS accumulation confer tolerance to many diverse lethal agents.Patients with rheumatoid arthritis (RA) taking long-term immunosuppressive drugs are more susceptible to opportunistic infections, such as cryptococcosis. A 65-year-old woman was transferred to our hospital for rapidly progressing pulmonary lesions identified by lung computed tomography. She had a 7-year history of RA and had been prescribed methotrexate and glucocorticoids for 10 months. Additionally, our patient had a history of environmental exposure to house renovation lasting approximately 1 week before onset. Her serological test results and histopathological examination confirmed the diagnosis of pulmonary cryptococcosis (PC). The patient recovered well after 6 months of fluconazole treatment. In addition, we summarized 28 reported cases of RA patients with PC and found that older age might be a risk factor for cryptococcal infection in RA patients. The most common location for pulmonary lesions was the lower lobe, and the most common radiologic manifestations were nodules. Detection of cryptococcal capsular polysaccharide antigen was important for diagnosis. Patients undergoing antirheumatic therapy should avoid exposure to Cryptococcus. The management of squamous cell carcinoma (SCC) of the tongue represents the most demanding treatment planning in head and neck surgery. Ablation followed by free flap reconstruction is considered the gold standard, but not all patients are suitable for this strategy. The aim of this review is to provide a comprehensive view of surgical reconstruction possibilities in patients not eligible for free flaps. Following PRISMA recommendations, a systematic literature review was conducted searching for original papers that investigated outcomes of patients treated by surgical ablation for tongue SCC followed by reconstruction with local or pedicled flaps. BTXA51 Selected papers were read and data extracted for qualitative analysis. Twenty articles met the inclusion/exclusion criteria. The study design was case series in sixteen papers, cohort study in the remaining four. Four different local flaps (BMM, FAMM, NLIF, SMIF) and four regional flaps have been discussed in included studies (IHF, SFIF, SCM, PMMC). The improved anatomical knowledge makes local flaps a reliable alternative to free tissue transfer in cases requiring small-/medium-sized defects. Regional flaps still represent cornerstones in reconstruction of the tongue. Ease of execution, costs-to-benefit ratio, low
