Delayed thrombolytic treatment with recombinant tissue plasminogen activator (tPA) may exacerbate blood-brain barrier breakdown after ischaemic stroke and lead to lethal haemorrhagic transformation. The immune system is a dynamic modulator of stroke response, and excessive immune cell accumulation in the cerebral vasculature is associated with compromised integrity of the blood-brain barrier. We previously reported that regulatory T cells, which function to suppress excessive immune responses, ameliorated blood-brain barrier damage after cerebral ischaemia...

Ononis species are used for their laxative, diuretic, analgesic, anti-inflammatory, antiviral, cytotoxic and antifungal effects as well as against skin diseases for wound healing activity. In the light of this information n-hexane, ethylacetate and methanol extracts prepared from Ononis spinosa L. subsp. leiosperma (Boiss.) Sirj., Ononis variegata L., Ononis viscosa L. subsp. brevifolia (DC) Nym. and Ononis natrix L. subsp. natrix L. were tested for their wound healing, anti-inflammatory and antioxidant activities...

Door-Needle-times (DNT) of 20min are feasible when Computer Tomography (CT) is used for first-line brain-imaging to assess stroke-patients' eligibility for intravenous-tissue-Plasminogen-Activator (iv-tPA), but the more time-consuming Magnetic Resonance Imaging (MRI)-based-evaluation is superior in detecting acute ischaemia.

INTRODUCTION: Tumor progression and neovascularization during malignant processes are believed to be associated with plasminogen activators and the PAI-1 inhibitor, but their role and interactions in various types of brain tumors have been studied insufficiently. AIM: To conduct a comparative study of plasminogen regulation in optic nerve sheath meningiomas, glioblastomas, and brain metastases of breast cancer, as well as in perifocal tissues surrounding the tumors...

BACKGROUND: Coagulopathy is associated with massive transfusion in trauma, yet most clinical scores to predict this end point do not incorporate coagulation assays. Previous work has identified that shock increases circulating tissue plasminogen activator (tPA). When tPA levels saturate endogenous inhibitors, systemic hyperfibrinolysis can occur. Therefore, the addition of tPA to a patient's blood sample could stratify a patients underlying degree of shock and early coagulation changes to predict progression to massive transfusion...

Solution-processed hole transporting materials (HTMs) that are dopant-free show promise for use in low-cost, high performance perovskite solar cells (PSCs). The highest efficiency PSCs use organic HTMs, many of which have low mobilities and so require doping, which lowers the device stability. Additionally, these materials are not easily scaled because they often require complicated synthesis. Two novel HTMs (IDT-TPA and IDTT-TPA) were synthesized, which contained either an extended fused-ring indacenodithiophene (IDT) or indacenodithienothiophene (IDTT) core and strong electron donating methoxytriphenylamine (TPA) groups as the end-capping units...

The present study was aimed at investigating the modulatory effects of folic acid (FA) on early stages of chemically induced skin cancer. For this, a two-stage model of skin tumorigenesis was employed. 7,12-Dimethylbenz(a)anthracene (DMBA, 500 nmol/100 ul of acetone) was applied topically for two weeks (twice weekly), followed by phorbol-12-myristate-13-acetate (TPA, 1.7 nmol/100 ul) twice weekly for six weeks on the depilated skin of mice, and FA was administered orally at a dose of 40 microgram/animal for 10 weeks daily...

Stimulation of glucose transport is an important determinant of myocardial susceptibility to ischemia and reperfusion. Stimulation of glucose transport is markedly impaired in cardiomyocytes exposed to free fatty acids (FFA). Deactivation of the Focal Adhesion Kinase (FAK) by FFA contributes to glucose transport impairment, and could be corrected by chronic treatment with the phorbol ester TPA. However, TPA must have effects in addition to FAK reactivation to restore stimulated glucose transport. Chronic treatment with TPA improved basal and stimulated glucose transport in FFA-exposed, but not in control cardiomyocytes...

BACKGROUND: Atrial fibrillation (AF) is the most common arrhythmia and a common cause of ischemic stroke. Stroke patients with AF have been shown to have a poorer neurological outcome than stroke patients without AF. OBJECTIVES: To determine the impact of pre-existing AF on residual degree of disability in patients treated with IV thrombolysis. METHODS: In this case-control study, data of 214 stroke patients (63 with AF and 151 without AF) were collected from the National Acute Stroke Israeli Registry, a nationwide quadrennial stroke database...

A new cocrystal of 4-Styrylpyridine and 1,2,4,5-Tetracyanobenzene has been successfully achieved through supramolecular self-assembly, in which the donor-acceptor interactions as the main self-assembly driving force contribute to the intermolecular charge transfer (ICT). Attractively, interesting two-photon absorption (TPA) properties are generated from the co-crystals which does not find in their individual single components. It is found that the TPA properties are originated from the ICT interactions in the D-A system...

BACKGROUND AND PURPOSE: We conducted a randomized exploratory study to assess safety and the probability of a favorable outcome with adjunctive argatroban, a direct thrombin-inhibitor, administered to recombinant tissue-type plasminogen activator (r-tPA)-treated ischemic stroke patients. METHODS: Patients treated with standard-dose r-tPA, not receiving endovascular therapy, were randomized to receive no argatroban or argatroban (100 μg/kg bolus) followed by infusion of either 1 (low dose) or 3 μg/kg per minute (high dose) for 48 hours...

We report a case of syringocystadenoma papilliferum (SCAP) combined with tubular papillary adenoma (TPA) arising on the chest of a 45-year-old Japanese woman. Histopathological examination revealed the characteristic findings of SCAP in the superficial part of the lesion and those of TPA in the deeper part. We reviewed the English literature about this combination. SCAP and TPA have the same cellular components, but show differences of the general structure. The combination of these two neoplasms is more frequent than expected by most dermatopathologists or pathologists...

BACKGROUND CONTEXT: Prior reports have compared posterior column osteotomies to pedicle subtraction osteotomies in terms of utility for correcting fixed sagittal imbalance in adolescent patients with deformity. No prior reports have described the use of multilevel Smith-Petersen Osteotomies (SPOs) alone for surgical correction in the adult spinal deformity (ASD) population. PURPOSE: To determine the utility of multilevel Smith-Petersen Osteotomies (SPOs) in the management of global sagittal imbalance in adult spinal deformity (ASD) patients...

REVIEW
Richard R Heuser
Even though cardiovascular disease (CVD) is still the leading cause of death in the United States, stroke is the second leading of global cause of death behind CVD . In the 21st Century, less than 40% of overall stroke patients are discharged to home and almost 25% of Medicare beneficiaries do not survive 90days. In spite of the fact that tissue plasminogen activator (TPA) has been approved for stroke care for 20years, only .75% of annual strokes are actually treated with intravenous (IV) TPA. Similar to how interventional cardiologists evolved from IV to catheter mechanical treatment for acute myocardial infarctions (AMI) over 30years ago, over the last few years, neurointerventionists now perform endovascular stroke therapy in many of these patients using stent retrievers...

Stroke has been emerged as one of major health problems for women worldwide. Increasing of knowledge in this field provided new data in this area which contribute to finding of new risk factors and could improve stroke treatment. A large number studies indicated a variety of risk factors including sex, age, race, smoking, diabetes, and physical inactivity could be involved in stroke in women. The understanding of various aspects involved in women stroke including risk factors, outcomes, stroke recovery, and prevention could provide new therapeutic platforms which could likely lead to better treatment in women stroke...

BACKGROUND AND PURPOSE: Energy depletion is a critical factor leading to cell death and brain dysfunction after ischemic stroke. In this study, we investigated whether energy depletion is involved in hyperglycemia-induced hemorrhagic transformation after ischemic stroke and determined the pathway underlying the beneficial effects of hyperbaric oxygen (HBO). METHODS: After 2-hour middle cerebral artery occlusion, hyperglycemia was induced by injecting 50% dextrose (6 mL/kg) intraperitoneally at the onset of reperfusion...

BACKGROUND AND PURPOSE: Because of the limitation in treatment window of the r-tPA (recombinant tissue-type plasminogen activator), the development of delayed treatment for stroke is needed. In this study, we examined the efficacy of delayed poststroke treatment (post 3-8 days) of the sonic hedgehog pathway agonist on functional recovery and the underlying mechanisms. METHODS: We evaluated functional recovery at 1 month after stroke using locomotion analysis and Barnes maze test for cognitive function...

BACKGROUND AND PURPOSE: Rapid recognition of those at high risk for malignant edema after stroke would facilitate triage for monitoring and potential surgery. Admission data may be insufficient for accurate triage decisions. We developed a risk prediction score using clinical and radiographic variables within 24 hours of ictus to better predict potentially lethal malignant edema. METHODS: Patients admitted with diagnosis codes of cerebral edema and ischemic stroke, NIHSS score (National Institute of Health Stroke Score) of ≥8 and head computed tomographies within 24 hours of stroke onset were included...

A series of triphenylamine (TPA) substituted BODIPYs 1-3 have been newly designed and synthesized by the Pd catalysed Sonogashira cross-coupling and [2+2] cycloaddition-retroelectrocyclization reaction in good yields. This procedure yielded highly electron deficient tetracyanobutadiene (TCBD) or dicyanoquinodimethane (DCNQ) electron acceptor units centrally located at the TPA-BODIPY system. As a consequence, significant perturbation of the photonic and electronic properties were observed. The triads 2 and 3 showed red-shifted absorption in addition to a strong charge transfer type absorption in the case of 3...
