A new automated device for quantifying mechanical nociceptive responses.

J Neurosci Methods 2018 Dec 3. Epub 2018 Dec 3.

Department of Anesthesiology, Perioperative Care and Pain Medicine, New York University School of Medicine, New York, NY, USA; Department of Neuroscience and Physiology, New York University School of Medicine, New York, NY, USA. Electronic address:

Background: Traditional methods to assess pain in rodents depend on measures of nociceptive responses, most commonly from the hind paws. While these measures can quantify nociceptive responses to allow pharmacologic testing, they typically have high inter-experimenter variability and are not time-sensitive enough to correct with neural processes that occur on millisecond scales.

New Method: We have invented a pain detection device that uses changes in skin conductance to measure nocifensive withdrawal responses. Read More

Tissue Specificity in Trisomy 22 Mosaicism: A Tale of Caution for Interpretation of Chromosomal Microarray Results.

J Assoc Genet Technol 2018 ;44(4):137-140

Department of Pathology and Laboratory Medicine, University of Vermont Medical Center, Burlington, VT.

Objectives: While the complete form of trisomy 22 is seemingly incompatible with life, the mosaic form is a rare syndrome associated with developmental delays, intellectual disability, and dysmorphic features. Due in part to the difficulty of analyzing chromosomal mosaicism, many instances either go undiagnosed or have their diagnosis delayed. We report a case of mosaic trisomy 22 in a diamnionic-dichorionic twin with marked growth discordance and intra-uterine growth restriction, diagnosed in a 2-year-old with developmental delays, sensorineural hearing loss, cardiac and gastrointestinal abnormalities, and osteopenia of prematurity.

Ventilatory responses to acute hypoxia and hypercapnia in humans with a patent foramen ovale.

J Appl Physiol (1985) 2018 Dec 6. Epub 2018 Dec 6.

School of Health and Exercise Science, University of British Columbia, Canada.

Subjects with a patent foramen ovale (PFO) have blunted ventilatory acclimatization to high altitude, compared to subjects without PFO. The blunted response observed could be due to differences in central and/or peripheral respiratory chemoreflexes. We hypothesized that compared to subjects without a PFO (PFO-), subjects with a PFO (PFO+) would have blunted ventilatory responses to acute hypoxia and hypercapnia. Read More

Extracellular vesicles from mature dendritic cells (DC) differentiate monocytes into immature DC.

Life Sci Alliance 2018 Dec 3;1(6):e201800093. Epub 2018 Dec 3.

Department of Dermatology, University Hospital Erlangen, Kussmaul Campus, Erlangen, Germany.

During inflammation, murine and human monocytes can develop into dendritic cells (DC), but this process is not entirely understood. Here, we demonstrate that extracellular vesicles (EV) secreted by mature human DC (maDC) differentiate peripheral monocytes into immature DC, expressing a unique marker pattern, including 6-sulfo LacNAc (slan), Zbtb46, CD64, and CD14. While EV from both maDC and immature DC differentiated monocytes similar to GM-CSF/IL-4 stimulation, only maDC-EV produced precursors, which upon maturation stimulus developed into T-cell-activating and IL-12p70-secreting maDC.

Genetic polymorphism of the methotrexate transporter ABCG2, blood pressure and markers of arterial function in patients with rheumatoid arthritis: repeated cross-sectional study.

Pharmgenomics Pers Med 2018 12;11:205-210. Epub 2018 Nov 12.

Department of Clinical Pharmacology, College of Medicine and Public Health, Flinders University and Flinders Medical Centre, Adelaide, SA, Australia.

Purpose: Methotrexate (MTX) treatment is associated with lower blood pressure (BP) and arterial stiffness in rheumatoid arthritis (RA). We investigated associations between single-nucleotide polymorphism (SNP) of the ATP-binding cassette efflux transporter gene (rs2231142), BP, and arterial stiffness in RA patients treated with MTX.

Patients And Methods: Clinical and 24-hour peripheral and central BP, arterial wave reflection (Augmentation Index, AIx), arterial stiffness (Pulse Wave Velocity, PWV), and intracellular MTX polyglutamate (MTXPGs) concentrations were assessed in 56 RA patients on stable treatment with MTX using a repeated cross-sectional study design with measurements at baseline and after 8 months.
