Stroke is one of the leading causes of death and disability worldwide. Scalp acupuncture and exercise therapy have been proven as two effective methods for the treatment of stroke. However, their combined action and mechanisms have not been fully elucidated. The present study aimed to investigate the protective effect of scalp acupuncture combined with exercise therapy on neurons in rats with ischemic brain injury.
 
  100 rats were randomly divided into 5 groups including sham group, model group, acupuncture group, rehabilitation group, and experimental group (scalp acupuncture combined with exercise therapy). Middle cerebral artery occlusion (MCAO) model in rats was established according to Longa modified suture method to mimic ischemic stroke. The modified Bedexer's neurological function score was used to evaluate the neurological deficits of rats and the brain infarct volume was measured using 2, 3, 5-triphenyl tetrazolium chloride monohydrate (TTC) staining. Moreover, the apoptosis in the hippocampus washabilitation group were significantly lower than those in the model group, but higher than the experimental group. While the opposite results were obtained in SOD activity. Furthermore, compared with the model group, the ratios of BDNF, S100β, and GFAP-positive cells in the acupuncture, rehabilitation and experimental groups were significantly increased, and the highest ratios were recorded in the experimental group.
 
  This study demonstrated that scalp acupuncture combined with exercise therapy effectively counteracts ischemic brain injury via the downregulation of pro-inflammatory mediators and ROS, the increased production of the antioxidant enzyme SOD, neurotrophic factor BDNF and astrocyte activities.

  Prior literature suggests after-hours delay leads to poor functional outcomes in stroke patients undergoing thrombectomy. We aimed to evaluate the impact of time of presentation on mechanical thrombectomy (MT) metrics and its association with long-term functional outcome in an Interventional Radiology (IR) suite equipped operating room (OR) setting.
 
  Retrospective review of prospectively maintained database on all stroke patients undergoing mechanical thrombectomy between January 2015 and December 2018 at our CSC. Work hours were defined by official OR work hours (Monday-Friday 7 AM and 5 PM) and after-hours as between 5 PM and 7 AM during weekdays and weekends as well as official hospital holidays. Primary outcome was 90-day modified Rankin Scale (mRS). Secondary outcomes included door to groin puncture time and procedural complications.
 
  A total of 315 patients were included in the analyses. 209 (66.4%) received mechanical thrombectomy after hours and 106 (33.6%) during work hours. There was no differen
  There is scant data related to prehospital delay in cases of acute ischemic stroke from multicenter studies conducted after change of the therapeutic window of intravenous tissue plasminogen activator (iv-tPA) administration to within 4.5h of onset. We investigated factors causing prehospital delay and their associations with clinical outcomes using data from a regional multicenter stroke registry.
 
  Data from the multicenter regional stroke registry were analyzed. Patients admitted within 24h of the last known well time were categorized according to whether their admission was early (≤ 4h; n = 2350) or delayed (> 4h; n = 2752). We then compared patients' backgrounds and outcomes between the two groups.
 
  Five-thousand, one-hundred two patients presented at hospitals within 24h of onset. On multivariate analysis, atrial fibrillation, higher NIHSS score on admission, anterior circulation stroke, detection of symptoms immediately after onset, and emergency system use were positively associated with early aities to general population or public awareness campaigns.
  Intracranial hemorrhage (ICH) catastrophically damages the cerebral vasculature, and severely compromises blood-brain barrier (BBB) function. The prognosis of ICH is poor due to the drastic and rapid progression of its pathology, and the lack of effective treatments presents a significant unmet clinical need. The present paper provides several evidences about the relationship between ICH bleeding status and mortality and the potential therapeutic effects of an iron chelator for ICH.
 
  Zebrafish are a highly transparent animal model, allowing live imaging of the complex cerebral vasculature. Thus, to further elucidate ATV-induced ICH, we investigated the concentration- and time-dependent phenotypes of ATV-induced ICH with zebrafish larvae.
 
  The effects of ATV on mortality and ICH incidence in zebrafish larvae were concentration-dependent.  https://www.selleckchem.com/products/Temsirolimus.html  Further, ATV treatment decreased vascular density of the hindbrain in a concentration-dependent manner, and hematoma volume was inversely correlated with ATV concentration. The number of cranial TUNEL-positive apoptotic cells was markedly increased 3 days post-fertilization. Importantly, the iron chelator deferasirox (DFR) decreased the incidence of ATV-induced ICH in zebrafish larvae.
 
  These findings provided insight into the pathology and regulatory mechanism of ATV-induced ICH, and demonstrated the therapeutic effects of iron chelators.

As the pandemic continues, a growing body of evidence suggests that infected patients may develop significant coagulopathy with resultant thromboembolic complications including deep vein thrombosis, pulmonary embolism, myocardial infarction, and ischemic stroke. However, this data is limited and comes from recent small case series and observational studies on stroke types, mechanisms, and outcomes.1-14 Furthermore, evidence on the role of therapeutic anticoagulation in SARS-CoV-2 infected patients with elevated inflammatory markers, such as D-dimer, is also limited. We report the case of a middle-aged patient who presented with a large vessel ischemic stroke likely resulting from an underlying inflammatory response in the setting of known novel coronavirus infection (COVID-19). Histopathologic analysis of the patient's ischemic brain tissue revealed hypoxic neurons, significant edema from the underlying ischemic insult, fibrin thrombi in small vessels, and fibroid necrosis of the vascular wall without any signs of vasculature inflammation.
