Background and Purpose--Reperfusion is the most beneficial of all therapeutic strategies for acute ischemic stroke. However, the standard cerebral reperfusion treatment of the first decade of the reperfusion era, noncontrast computed tomography CT ; guided, 3 hours, intravenous tissue plasminogen activator, has many limitations. This review surveys emerging strategies that have the potential to extend cerebral reperfusion therapy to larger numbers of patients. Summary of Review--Innovative intravenous pharmacological reperfusion strategies include novel fibrinolytic agents tenecteplase, reteplase, desmetolplase, plasmin, and microplasmin ; , glycoprotein GP ; IIb IIIa antagonists with platelet disaggregating effects abciximab and tirofiban ; , combination therapies to improve efficacy of clot lysis fibrinolytics and GP IIb IIIa agents, and fibrinolytics and direct thrombin inhibitors ; , increase the time window for clot lysis fibrinolytics and neuroprotectants ; , and reduce the frequency of hemorrhagic complications fibrinolytics and vasoprotectants ; , and externally applied ultrasound to enhance enzymatic fibrinolysis. Promising intra-arterial pharmacological reperfusion approaches include novel fibrinolytic agents, combined intravenous and intra-arterial fibrinolysis, and combined fibrinolytics and GP IIb IIIa agents. Emerging endovascular mechanical reperfusion strategies include intra-arterial thrombectomy clot retrieval devices and suction thrombectomy devices ; , mechanical disruption micro-guidewire passage, laser photoacoustic emulsification, and primary intracranial angioplasty ; , and augmented fibrinolysis by endovascular ultrasound. Multimodal imaging, with magnetic resonance MR ; or CT, can rapidly assess infarct core, penumbra, site of vessel occlusion, and tissue hemorrhagic propensity, enabling improved selection of patients for reperfusion therapy beyond any arbitrary fixed time window. Conclusions--Therapeutic reperfusion is emerging as a treatment strategy of remarkable power and scope for rescuing patients experiencing acute brain ischemia, applicable within and beyond the 3-hour time window.

Departments of * Neurobiology and Immunology, The Weizmann Institute of Science, Rehovot, Israel To read the full text of this article, go to : fasebj cgi doi 10.1096 fj.05-4540fje; doi: 10.1096 fj.05-4540fje SPECIFIC AIMS Chondroitin sulfate proteoglycans CSPGs ; are a matrix component expressed naturally in the central nervous system CNS ; and up-regulated after CNS injuries and during the course of chronic neurodegenerative disorders such as multiple sclerosis MS ; , Alzheimer's disease, and glaucoma. They are considered to be a major factor inhibiting regeneration in the CNS due to their growth inhibitory effect on neurons and their association with activation of immune components. Studies have shown that degradation of CSPGs in vivo, using the enzyme chondroitinase ABC, promote recovery. We postulated that a disaccharidic degradation product of these glycoproteins CSPG-DS ; participates in the modulation of the inflammatory response and might therefore have potential as a treatment for inflammation-associated neurodegenerative conditions in the CNS. The aim of this study was to test this hypothesis by examining the ability of CSPG-DS to promote recovery and neuronal survival in the models of experimental autoimmune encephalomyelitis EAE ; and experimental autoimmune uveitis EAU ; and to test its effects on components of the immune system such as T cells and microglia macrophages. induced disease with increasing numbers of CSPG-DS injections. Repeated treatment with CSPG-DS also significantly delayed disease onset day 15.5 0.7 after disease induction in the CSPG-DS treated mice vs. 12.5 1 in the control ; and shortened its duration. 2. CSPG-DS protects against loss of retinal ganglion cells in EAU To determine whether the effect of CSPG-DS found in EAE is applicable to other neuroinflammatory conditions and to accurately measure the ability of CSPG-DS to protect neurons, we used an animal model of inflammation-mediated neuropathology in the eye, known as EAU. In this model the inflammatory response in the eye causes loss of neurons RGCs ; , which can be accurately quantified. Treatment with steroids, while alleviating the inflammatory response, causes further death of RGCs. Such a situation makes this model an ideal system to test the potential dual function of CSPG-DS in controlling inflammation and in neuronal rescue. EAU was induced in Lewis rats by active immunization with a pathogenic peptide R16 ; derived from interphotoreceptor retinoid binding protein, IRBP, emulsified in CFA. Three groups of the EAU-induced rats were included. One group was injected i.v with the steroid drug, methylprednisolone MP ; , the second group with CSPG-DS, and the third group with PBS only control ; . Immunization of naive Lewis rats with R16 was found to cause RGC loss of 52 2% mean sd ; relative to normal rats. Treatment of R16-immunized rats with MP had no beneficial effect on neuronal survival and even caused further RGC loss 59 1.6% ; . In contrast, treatment of the R16-immunized rats with CSPG-DS reduced the RGC loss to 24 9% Fig. 1A.

Unlike executives of health systems that actually provide health care, where increased efficiency is linked to management skill that actually lowers costs and should be appropriately rewarded, health insurers add cost into the health system, and encounter few impediments to raising premiums to reach predetermined levels of profit oops, I mean surplus ; . They seem to spend much less time worrying about managing for greater efficiency, and far more time looking for mergers and acquisitions. But these are not evil or ignorant people. They doubtless view themselves favorably, and have rationalized their exorbitant salaries and inefficient management as simply their just due for their successful effort so far ; to keep the health care system mainly subject to the forces of the free market. Humans are peculiar. We can live for a week without food, but not one day without rationalizing. Administrative costs account for about 20 percent of each health-care dollar. An important portion of the revenue for these "health insurance" companies consists of processing claims paid by other parties, such as Medicare or self-insured employers, for which the intermediaries take a generous cut. In providing these administrative services, they aren't functioning as at-risk insurance companies, and in the communities they serve, they often enjoy a near monopoly or share an oligopoly. As regional administrators for Medicare, they generate considerable revenue from operations that involve no risk, and there is often little free market competition that demands efficiency and transparency. This phenomenon leads to an unending upward spiral in premiums and revenue, which also takes even more money out of the system for executive compensation. Last year, the 10 top executives at Highmark received 41 percent pay increases, raising their aggregate pay from million to .3 million in one year. It also means that "non-profits" have succumbed to the same disease of unbridled executive compensation that has infected major publicly held corporations, though for different reasons. Publicly traded corporations don't ordinarily have near monopolies or oligopolies in their region or industry, and they cannot simply raise prices. The "non-profits" are also sheltered by the public's illusion that their sole concern is the commonweal, so they can go merrily on their inefficient ways because they all have similar levels of inefficiency and similarly overpaid executives.

ABSTRACT The predominant subclasses of mast cells in both the rat and the mouse can be distinguished from one another by their preferential synthesis of 35S-labeled proteoglycans that contain either heparin or oversulfated chondroitin sulfate glycosaminoglycans. Mthough [35SIheparin proteoglycans have been isolated from human lung mast cells of 40-70% purity and from a skin biopsy specimen of a patient with urticaria pigmentosa, no highly sulfated chondroitin sulfate proteoglycan has been isolated from any enriched or highly purified population of human mast cells. We here demonstrate that human lung mast cells of 96% purity incorporate [35s] sulfate into separate heparin and chondroitin sulfate proteoglycans in an -2: 1 ratio. As assessed by HPLC of the chondroitinase ABC digests, the chondroitin [35S]sulfate proteoglycans isolated from these human lung mast cells contain the same unusual chondroitin sulfate E disaccharide that is present in proteoglycans produced by interleukin 3-dependent mucosallike mouse mast cells. Both the chondroitin [35SJsulfate E proteoglycans and the [35S]heparin proteoglycans were exocytosed from the [35S]sulfate-labeled cells via perturbation of the IgE receptor, indicating that both types of S-labeled proteoglycans reside in the secretory granules of these human lung mast cells and cladribine.
Tive heparin-binding sites was compared with the TNIII4 5 wild-type protein. The results from SPR-based Biacore are summarized in Table II. The KD for recombinant TNIII4 5 K751Q K754Q exhibited a reduced affinity KD 29.2 M ; for heparin compared with TNIII4 5 70-fold ; . As expected, mutations of the KGR sequence in the TNIII5 domain, TNIII4 5 K1057Q and TNIII4 5 R1059Q, result in complete inhibition of heparin binding Table II ; . Based on these data, we conclude that the TNIII5 domain is the primary heparin-binding site, and residues at Arg1059 and Lys1057 in this domain are of critical importance in the interaction. The fact that mutations of the KEDK sequence in the TNIII4 domain reduced affinity for heparin strongly indicates that the complete heparin binding in TN-C relies on secondary heparin binding formed by KEDK residues. These results suggest that the KEDK residues in the loop region between F and G strands contribute to an optimal heparin binding activity of TN-C, and heparin-binding sites in TN-C may span both of the TNIII4 and TNIII5 domains. Role of Heparin-binding Domain of TNIII4 in Cell Adhesion--To investigate the biological significance of the heparinbinding domain of TNIII4, we explored whether a heparinbinding property was relevant to the process of cell adhesion. HGFs were plated on dishes coated with a series of TNIII fragments. When HGF cell adhesion to a TNIII fragmentcoated dish was quantitated by the crystal violet staining of fixed cells, TNIII4 5 exhibited significantly higher adhesive activity than TNIII5. Notably, the cell binding to TNIII4 5 K751Q K754Q was significantly reduced. Moreover, the adhesion of HGF to TNIII4 5 was completely abrogated by the presence of 5 g heparin in the plating medium. These results suggest that prior occupancy of the heparin-binding sites in TNIII4 5 by soluble heparin might cause interference with its ability to bind to cell surface HSPGs. To test this possibility, cell surface HSPGs were removed from HGF by treatment of the cells with heparinase I, an enzyme that acts on highly sulfated HSPGs 32 ; . Heparinase I digestion of HGF cell surfaces reduced the number of TNIII4 5-binding sites by 75%. In control experiments, treatment of HGF with chondroitinase ABC failed to inhibit a TNIII4 5-mediated adhesion of HGF showing that cell surface heparan sulfates, but not chondroitin sulfates, contribute to the cell-adhesive properties of TNIII4 5 Fig. 4 ; . Taken together, these results support the conclusion that TNIII4 contains binding sites for HSPGs and.

Cause of continuing platelet activation. The results could also explain the common serologic finding of heparin-independent platelet activation.3, 5 Rauova and colleagues further found that the effects of pharmacologic heparin on binding of KKO to platelets differ depending upon the amount of PF4. When relatively low PF4 concentrations were present 12.5 and 50 g mL ; , added heparin led to reduced antibody binding. In contrast, when high PF4 concentrations were present 200 g mL ; , addition of heparin increased antibody binding to platelets. These data indicate that patient-dependent differences in platelet-associated PF4 quantity could significantly influence risk of HIT see figure ; . The authors further tested these concepts using a murine model of HIT in which various mouse lines expressing human Fc IIA receptors Fc RIIA ; and differing levels of human PF4 hPF4 ; were evaluated for thrombocytopenia after intraperitoneal injection with KKO. Whereas Fc RIIA hPF4high doubletransgenic mice developed severe and persisting thrombocytopenia, Fc RIIA hPF4low mice exhibited only mild, transient platelet count reduction. Pretreatment with protamine sulfate--a small positively charged molecule familiar to clinicians for its heparin-neutralizing properties--prevented thrombocytopenia in both Fc RIIA hPF4low and Fc RIIA hPF4high double-transgenic mice, presumably because protamine competes with PF4 for binding to platelet surface chondroitin sulfate. These intriguing results suggest that protamine should be evaluated in clinical studies for its potential to reduce HIT antibodyinduced and chondroitin.
