Summary: The study found that exposure to different concentrations of hyperoxia leads to activation of different oxygen-sensitive transcription factor patterns in human peripheral blood mononuclear cells. Mild hyperoxia is perceived as hypoxic stress, leading to activation of HIF-1α and NRF2, while high and very high concentrations of hyperoxia induce an oxidative stress response, characterized by activation of NRF2 and NF-κB.

Summary: Acute ischemic stroke (AIS) is a serious neurological disease, and normobaric hyperoxia (NBHO) is a non-invasive and easy method that can improve outcomes after cerebral ischemia/reperfusion. NBHO combined with recanalization, especially thrombolysis, has shown to improve neurological scores and long-term outcomes. Large randomized controlled trials (RCTs) are needed to determine their role in stroke treatment.

Summary: The tumor necrosis factor alpha (TNF-a)-TNF-a receptor (TNFR) interaction is crucial in the development of autoimmune diseases like rheumatoid arthritis, making it an important target for drug discovery. This study found that (-)-Epigallocatechin-3-gallate (EGCG), a polyphenolic compound found in green tea, can bind to TNF-a, TNFR1, and TNFR2 and disrupt their interactions. This leads to inhibition of TNF-a-induced cell death and NF-kB signaling pathway, suggesting that regular consumption of EGCG in green tea could potentially be used as a therapeutic agent for TNF-a-associated diseases.

Summary: Osteoporosis is a bone disease characterized by low bone quality and density, causing bone fragility and vulnerability to fractures. Increased osteoclast differentiation and activity contribute to bone loss, a common manifestation of osteoporosis. The TNF-a/NF-κB inflammatory pathway plays a key role in regulating osteoclast formation, along with the classical RANKL/RANK/OPG pathway. Probiotics, particularly Bifidobacterium, have shown potential beneficial effects on bone health by modulating this pathway. This review discusses the molecular mechanisms of the TNF-a/NF-κB pathway in osteoclast formation and explores the secretions produced by Bifidobacterium, providing new directions for future research.

Summary: Polyneuropathy (PNP) refers to diseases of the peripheral nervous system, with 50% of cases presenting with neuropathic pain. Certain types of PNP show pain restricted to the distal leg skin, indicating a local regulatory process leading to pain. This study suggests that a pro-inflammatory pathway mediated by NF-κB may contribute to pain development in patients with painful PNP. Our findings support the hypothesis of local inflammatory processes involved in pain in PNP, and suggest disrupted anti-inflammatory pathways in inflammatory PNP involving TRPV1 and SIRT1.

Summary: This article agrees with Dr. Pensato's opinion and proposes two practical approaches to save the ischemic penumbra, with a focus on normobaric hyperoxia plus endovascular therapy. The author emphasizes the importance of real-time imaging techniques to track the reversion of the ischemic core and achieve better clinical outcomes, calling for the development of new imaging techniques or refinement of existing ones.

Summary: Li et al. investigated the role of normobaric hyperoxia (NBO) in patients with anterior circulation ischemic stroke eligible for endovascular therapy. They demonstrated the feasibility, safety, and efficacy of NBO in a pilot randomized controlled trial, showing a smaller median final infarct volume and infarct volume growth in the treatment arm.

Summary: In this study, the post-translational modification of Tollip by ubiquitination was identified. Tollip interacts with RNF167 and RNF167 functions as the E3 ligase to attach poly-ubiquitin chains to Tollip. The ubiquitination of Tollip plays a crucial role in TNF-alpha signaling.

Summary: The study found that pretreatment of gastric cancer cells with triptolide can enhance its anti-tumor effect. This effect is dependent on the disruption of the H19/miR-204-5p/NF-kappa B/FLIP axis.

Summary: This study investigated the safety and efficacy of combining normobaric hyperoxia (NBO) with endovascular treatment (EVT) for acute ischemic stroke. The researchers found that NBO resulted in smaller infarct volume and lower mRS at 90 days. In response to comments, the authors suggested that a single round of hyperbaric oxygen therapy (HBOT) with EVT may be optimal, highlighting the ease of delivery of NBO compared to HBOT.

Summary: A signal-on nanobiosensor based on aptamers was developed for measuring salivary cortisol levels. This novel sensor allows for measurement of cortisol in saliva without contamination by needle stress. The sensor's ultrasensitive detection method and ability to perform measurements in a single tube make it suitable for cases where salivary cortisol levels are lower compared to serum cortisol.

Summary: This study investigated the protective effects and mechanisms of human placenta derived mesenchymal stem cells (hPMSCs) transplantation in a rat model of hypoxic-ischemic encephalopathy (HIE). The results showed that hPMSCs transplantation reduced apoptosis and improved long-term neurological prognosis. Furthermore, the downregulation of Sema 3A/NRP-1 expression and activation of the PI3K/Akt/mTOR signaling pathway played a key role in the protective effects of hPMSCs.

Summary: This study evaluated electrophysiological discrimination of parametric somatosensory stimuli in healthy young adults to understand how the brain processes the duration of tactile information. The results showed that participants did not electrophysiologically discriminate between 100 and 115 ms, but they exhibited distinct electrophysiological responses when the deviant stimuli were 130, 145, and 160 ms. These findings contribute to a better understanding of tactile sensitivity in different clinical conditions.

Summary: The basolateral amygdaloid complex (BLA) is closely involved in the formation of emotional memories, including both aversive memory and contextual fear memory. Acute sleep deprivation (SD) disrupts the acquisition of tone-associated fear memory in juvenile rats, but has no significant effect on contextual fear memory. Slow network oscillation in the amygdala contributes to the formation of amygdala-dependent fear memory in relation to sleep.

Summary: GSDME plays a crucial role in the pathogenesis of Alzheimer's disease by regulating the switch from apoptosis to pyroptosis and participating in neuroinflammatory response. Knockdown of GSDME has been shown to improve cognitive impairments, indicating that GSDME could be a therapeutic target for Alzheimer's disease.
