Acute hypothermia treatment (HT) is the only clinically established intervention following neonatal hypoxic-ischemic brain injury. However, almost half of all cooled infants still die or suffer from long-lasting neurological impairments. Regenerative therapies, such as mesenchymal stem cells (MSC) appear promising as adjuvant therapy. In the present study, we hypothesized that HT combined with delayed MSC therapy results in augmented protection, improving long-term neurological outcome. Postnatal day 9 (P9) C57BL/6 mice were exposed to hypoxia-ischemia followed by 4 hours HT...

OBJECTIVES: The deformability of erythrocytes is their ability to change shape in order to pass through the capillaries. Th is is necessary for quality of microcirculation and sufficient delivery of oxygen to the tissues. Th e aim of our study was to investigate the possible spontaneous changes in the erythrocyte deformability during day and evaluation of the possible direct effects of melatonin (hormone involved in regulation of biorhythms) on the erythrocyte deformability. METHODS: Samples of capillary blood were taken from 12 healthy volunteers in the morning (8:00) and early in the evening (16:30)...

Immune activation and inflammation participate in the progression of chronic heart failure (CHF). Th17 cells and CD4+CD25+ regulatory T (Treg) cells both come from naive Th cells and share reciprocal development pathways but exhibit opposite effects. We hypothesized that the Th17/Treg balance was impaired in patients with CHF, and exercise can improve it. Rats with ischemic cardiomyopathy were prepared by ligaturing the left anterior descending branch of the left coronary artery. Rats in training group were trained with treadmill; Th17 cells increased significantly while Treg cells significantly decreased in s by flow cytometry, and the peripheral blood level of IL-6, IL-17, and TNF-α was obviously elevated by ELISA assay...

Sonic Hedgehog (Shh) signaling induces neovascularization and angiogenesis. It is not known whether the hedgehog signaling pathway in endothelial cells is essential to angiogenesis. Smoothened (Smo) transduces hedgehog signaling across the cell membrane. This study assessed whether endothelial Smoothened-dependent Shh signaling is required for Shh-mediated angiogenesis and ischemic tissue repair. Endothelial-specific smoothened knockout mice, eSmo Null were created using Cre-lox recombination system. eSmo Null mice had no observable phenotype at baseline and showed normal cardiac function...

Although recent advances have overturned the old view of the human heart as an inert postmitotic organ, it is clear that the adult heart´s capacity to regenerate after an ischemic episode is very limited. Unlike humans, zebrafish and other lower vertebrates vigorously regenerate damaged myocardium after cardiac injury. Understanding how the zebrafish is able to conserve life-long cardiac regeneration capacity while mammals lose it soon after birth is crucial for the development of new treatments for myocardial infarction...

BACKGROUND AND AIMS: Matrix metalloproteinase (MMP)-8 and myeloperoxidase (MPO) may contribute to cerebral damage in acute ischemic stroke. We tested the hypothesis that levels of MPO, MMP-8 and the ratio between MMP-8 and its regulator, tissue inhibitor of metalloproteinase (TIMP-1), are increased in acute ischemic stroke and its etiologic subgroups and they correlate with stroke severity. METHODS: In a cross-sectional case-control study, serum concentrations of MMP-8, MPO and TIMP-1 were assessed within 24 h after admission in 470 first-ever ischemic stroke patients and 809 age- and sex-matched controls, randomly selected from the population...

BACKGROUND: Polymerase δ-interacting protein 2 (Poldip2) is a multifunctional protein that regulates vascular extracellular matrix composition and matrix metalloproteinase (MMP) activity. The blood-brain barrier (BBB) is a dynamic system assembled by endothelial cells, basal lamina, and perivascular astrocytes, raising the possibility that Poldip2 may be involved in maintaining its structure. We investigated the role of Poldip2 in the late BBB permeability induced by cerebral ischemia...

BACKGROUND: In Africa, a high proportion of children are at risk for developmental delay. Early interventions are known to improve outcomes, but they are not routinely available. The Rwandan Ministry of Health with Partners In Health/Inshuti Mu Buzima created the Pediatric Development Clinic (PDC) model for providing interdisciplinary developmental care for high-risk infants in rural settings. As retention for chronic care has proven challenging in many settings, this study assesses factors related to retention to care after 12 months of clinic enrollment...

BACKGROUND: "White cord syndrome" is a very rare condition thought to be the result of acute reperfusion of chronically ischemic areas of the spinal cord. Its hallmark is the presence of intramedullary hyperintense signal on T2-weighted MRI sequences in a patient with unexplained neurologic deficits following a spinal cord decompression. The syndrome is rare and has been reported previously in two patients following anterior cervical decompression and fusion. CASE DESCRIPTION: Here, we report an additional case of this complication in a 68-year-old man who developed acute left-sided hemiparesis after posterior cervical decompression and fusion for cervical spondylotic myelopathy...

Remote limb ischemic postconditioning (RIPoC) is a promising adjunct treatment for cerebral ischemia-reperfusion (IR) injury. However, the underlying mechanisms have not been fully elucidated yet. The present study aims to investigate potential involvement and regulatory mechanisms of autophagy in RIPoC treatment against cerebral IR injury in mice. Mice were subjected to 2 h middle cerebral artery occlusion (MCAO) then treated with vehicle, 3-methyladenine (3-MA, an autophagy inhibitor), or compound C (an AMPK inhibitor) at the onset of reperfusion...

Exercise training is a regular therapy for stroke patients in clinic. However, whether the early exercise is beneficial for stroke patients is still controversial. The review was performed in databases of OVID, PUBMED, and ISI Web of Science, from respective inception to December 2017. In this review, we summarize the effect of different exercise intensity, initiation time, and style on ischemic stroke. Moreover, the possible mechanism is also discussed. The conclusion is that the voluntary exercise is better in promoting the functional recovery following stroke compared to forced exercise; too early initiated exercise might play a harmful role following stroke, while early initiated exercise might exert benefits after stroke; mild and moderate intensity exercise training could generate better neuroprotection in comparison with high intensity exercise training; early excise training could regulate the process of brain edema, cell apoptosis, oxidative damage, stem cells and other mechanisms in order to exert neuroprotection for brain...
