Summary: MCAO and cerebral I/R injury can lead to microvascular injury, blood-brain barrier dysfunction, inflammation, oxidative stress, and neuronal death, resulting in brain infarction. HBOT has shown positive effects on neurological outcomes after these injuries, but conflicting data exists on its impact on functional recovery. Studies have been conducted to evaluate the potential benefits of HBOT, both in vivo and clinically, in the context of stroke outcomes.

Summary: In the STRATIS Registry, patients with M2 occlusions achieved similar rates of successful reperfusion, good functional outcome, and mortality compared to M1 occlusions, although there were increased rates of symptomatic intracranial hemorrhage in the M2 group. Further studies are needed to understand the benefits of mechanical thrombectomy for M2 occlusions.

Summary: In this study, the researchers found that poor outcome after stroke in patients with type 2 diabetes (DM2) is linked to impaired microvascular tissue reperfusion. Furthermore, they discovered differences in microvascular reperfusion response between male and female DM2 mice after transient middle cerebral artery occlusion (MCAO). These findings suggest that DM2 impairs capillary perfusion and exacerbates ischemic brain injury in male but not female mice with DM2.

Summary: Stroke is caused by ruptured or blocked cerebral blood vessels and subsequent disruption of brain blood circulation, resulting in rapid neurological deficits. The majority of stroke cases are ischemic strokes. Current treatments for ischemic stroke, such as t-PA thrombolytic therapy and surgical thrombectomy, can paradoxically lead to ischemia-reperfusion injury, exacerbating brain damage. Minocycline, a semi-synthetic tetracycline antibiotic, has demonstrated a wide range of neuroprotective effects independent of its antibacterial activity. In this article, we summarize the mechanisms underlying the protective effects of minocycline against cerebral ischemia-reperfusion injury, including modulation of oxidative stress, inflammatory response, excitotoxicity, programmed cell death, and blood-brain barrier injury. We also discuss the role of minocycline in alleviating stroke-related complications, providing a theoretical basis for its clinical application in cerebral ischemia-reperfusion injury.

Summary: This systematic review aims to evaluate the evidence of autophagy in acupuncture therapy for animal models of middle cerebral artery occlusion (MCAO). The study will include publications from various databases and use risk of bias assessment tools and the GRADE system to evaluate the quality of evidence. The results may provide insights into the mechanism of acupuncture therapy for ischemic stroke.

Summary: Celastrol, a compound isolated from traditional Chinese medicine, demonstrates effectiveness in protecting against cerebral ischemia/reperfusion injury. Through lipidomics analysis, it was found that celastrol can reduce cerebral infarct volume and apoptosis, and regulate lipid metabolism to exert its neuroprotective effects.

Summary: Basilar artery occlusion is a devastating neurological condition with high risks of disability and death. Despite the lack of randomized controlled trials, recent studies have shown that endovascular therapy (EVT) is beneficial for basilar artery occlusion within 24 hours of onset. These studies emphasized the importance of consecutive recruitment, fast enrollment, and minimizing cross-over to demonstrate the efficacy of EVT. This topical review examines and contextualizes the current evidence on EVT for basilar artery occlusion.

Summary: This study aimed to determine whether baseline delayed filling of the superficial middle cerebral vein (SMCV) was an independent cause of stroke prognosis in patients with acute anterior large vessel occlusion (LVO). The results showed a significant association between baseline delayed SMCV and a 3-month poor outcome, while SMCV reversal did not significantly change the stroke prognosis.

Summary: Using indocyanine green videoangiography (ICG-VA) can facilitate identification of potential recipient vessels and detection of pathological flow patterns. Recipients with initially low flow, late appearance, and retrograde flow direction appear to have the highest potential for flow increase.

Summary: The identification of novel targets to modulate the immune response triggered by cerebral ischemia is crucial for stroke therapeutics. This study revealed the involvement of tumour necrosis factor (TNF)-alpha-stimulated gene 6 (TSG-6) in regulating immune and stromal cell functions in acute neurodegeneration caused by ischemic stroke. The elevated levels of TSG-6 in the brain and peripheral blood indicate its potential detrimental role in the early reperfusion stage, while providing protection against brain infarct volume and neurological deficits when administered acutely. These findings highlight the important role of TSG-6 in ischemic stroke pathobiology and warrant further investigation.

Summary: The past decade has witnessed significant advancements in both diagnosis and treatment of cerebrovascular diseases, with the introduction of thrombectomy in ischemic stroke and the identification of new therapeutic targets based on deeper understanding of pathomechanisms. Additionally, translational aspects are increasingly recognized in basic science studies, enhancing their predictive value for clinical application.

Summary: The perivascular tissue surrounding the middle cerebral artery plays a critical role in regulating vessel function through sphingosine-1-phosphate (S1P)-induced vasoconstriction. The presence of the arachnoid membrane is associated with reduced MCA diameters and increased basal tone, with strong S1P signals detected in the arachnoid. Additionally, genetic deletion of SphK2 reduces arachnoid S1P content and vasoconstriction.

Summary: A variant of SARS-CoV-2, 20E (EU1), was identified in Spain in early summer 2020 and later spread across Europe. Despite not showing increased transmissibility, the variant's success can be attributed to rising incidence in Spain, resumption of travel, and lack of effective screening and containment measures. Travel played a significant role in introducing the variant multiple times to European countries during the summer, undermining local efforts to prevent SARS-CoV-2 infection.

Summary: This study reveals that XOR plays a role in the progression of MFS aortopathy, and inhibiting XOR can halt the development of aortic root aneurysm in MFS mice. The study also suggests that redox stress is an important determinant of aortic aneurysm formation and progression in MFS, and further evaluation of XOR inhibitors in MFS patients is warranted.

Summary: Severe carotid atherosclerosis may worsen endothelial dysfunction in stroke, increasing the risk of further cerebrovascular events. Serum from stroke patients induces endothelium dysfunction in mice carotid arteries, especially in patients with recurrent strokes or vascular death within 1 year. Serum from patients with high-grade stenosis induces more severe carotid artery endothelial dysfunction, associated with elevated levels of circulating IL-1 beta. The study suggests that targeting COX in the carotid artery wall may be a potential therapeutic strategy for secondary stroke prevention.

Summary: This study aimed to identify modified LDLs and antioxidant enzymes associated with plaque vulnerability in patients with ischemic stroke and carotid atherosclerosis. Patients showed lower levels of cholesterol and apolipoproteins, as well as lower enzymatic activities of PAF-AH and PON-1 in HDL and higher levels of oxidized LDL and electronegative LDL. The proportion of LDL(-) was independently associated with carotid stenosis, hypoechoic plaque presence, and diffuse neovessels.

Summary: This study provides the first evidence that TRPV2 channels may modulate vascular tone by balancing opposing inputs from the endothelium and smooth muscle, leading to net vasodilation. The amplification of TRPV2 channel-induced activity by NO emphasizes the pathophysiological relevance of these findings.
