Use of the Revised Second Victim Experience and Support Tool to Examine Second Victim Experiences of Respiratory Therapists.

Background: Respiratory therapists (RTs) work alongside allied health staff, nurses, and physicians during stressful and traumatic events that can be associated with emotional and physiological implications known as second victim (SV) experiences (SVEs). This study aimed to evaluate SVEs of RTs, including both positive and negative implications.

Methods: RTs within a large academic health care organization across Minnesota, Wisconsin, Florida, and Arizona were asked to participate in an anonymous survey that included the validated Second Victim Experience and Support Tool-Revised to assess SVEs as well as desired support services.

Neuregulin1 modulation of experimental autoimmune encephalomyelitis (EAE).

Neuregulin1 (NRG1) is a differentiation factor that regulates glial development, survival, synaptogenesis, axoglial interactions, and microglial activation. We previously reported that a targeted NRG1 antagonist (HBD-S-H4) given intrathecally, reduces inflammatory microglial activation in a spinal cord pain model and a neurodegenerative disease mouse model in vivo, suggesting that it may have effects in neuroninflammatory and neuronal disorders. We hypothesized that expression of HBD-S-H4 in the central nervous system (CNS) could reduce disease severity in experimental autoimmune encephalomyelitis (EAE), a widely used animal model for multiple sclerosis (MS).

Slowing disease progression in the SOD1 mouse model of ALS by blocking neuregulin-induced microglial activation.

There are no effective treatments to slow disease progression in ALS. We previously reported that neuregulin (NRG) receptors are constitutively activated on microglia in the ventral horns in both ALS patients and SOD1 mice and in the corticospinal tracts of ALS patients, and that NRG receptor activation occurs prior to significant clinical disease onset in SOD1 mice. Here, we hypothesize that blocking NRG signaling on microglia would slow disease progression in SOD1 mice using a targeted NRG antagonist (HBD-S-H4).

Folate Receptor Alpha Upregulates Oct4, Sox2 and Klf4 and Downregulates miR-138 and miR-let-7 in Cranial Neural Crest Cells.

Prenatal folic acid (FA) supplementation prevents neural tube defects. Folate receptor alpha (FRα) is critical for embryonic development, including neural crest (NC) development. Previously we showed that FRα translocates to the nucleus in response to FA, where it acts as a transcription factor.

CD133 and DNA-PK regulate MDR1 via the PI3K- or Akt-NF-κB pathway in multidrug-resistant glioblastoma cells in vitro.

Chemotherapy is an adjuvant treatment for glioblastomas, however, chemotherapy remains palliative because of the development of multidrug resistance (MDR). Following prolonged chemotherapy, MDR protein 1 (MDR1) and CD133 increase in recurrent glioblastomas. CD133 positive (CD133+) glioma cancer stem-like cells (GCSCs) markedly promote drug resistance and exhibit increased DNA damage repair capability; thus they have a key role in determining tumor chemosensitivity.

A critical role of noggin in developing folate-nonresponsive NTD in Fkbp8 -/- embryos.

Purpose: Maternal folate intake has reduced the incidence of human neural tube defects by 60-70 %. However, 30-40 % of cases remain nonresponsive to folate intake. The main purpose of this study was to understand the molecular mechanism of folate nonresponsiveness in a mouse model of neural tube defect.

Amniotic fluid and serum biomarkers from women with neural tube defect-affected pregnancies: a case study for myelomeningocele and anencephaly: clinical article.

Object: The authors sought to identify novel biomarkers for early detection of neural tube defects (NTDs) in human fetuses.

Methods: Amniotic fluid and serum were drawn from women in the second trimester of pregnancy. The study group included 2 women pregnant with normal fetuses and 4 with fetuses displaying myelomeningocele (n = 1), anencephaly (n = 1), holoprosencephaly (n = 1), or encephalocele (n = 1).

Convection-enhanced delivery of nanodiamond drug delivery platforms for intracranial tumor treatment.

Unlabelled: This study examined a novel drug delivery system for treatment of malignant brain gliomas: DOX complexed with nanodiamonds (ND-Dox), and administered via convection-enhanced delivery (CED). Drug retention and toxicity were examined in glioma cell lines, and distribution, retention and toxicity were examined in normal rat parenchyma. Efficacy was assessed in a bioluminescence rodent tumor model.

Uniform derandomization from pathetic lower bounds.

The notion of probabilistic computation dates back at least to Turing, who also wrestled with the practical problems of how to implement probabilistic algorithms on machines with, at best, very limited access to randomness. A more recent line of research, known as derandomization, studies the extent to which randomness is superfluous. A recurring theme in the literature on derandomization is that probabilistic algorithms can be simulated quickly by deterministic algorithms, if one can obtain impressive (i.
