Fire Dynamics in Boreal Forests Over the 20th Century : A Data-Model Comparison

Fire regimes across the world are expected to be altered by continuing variations in socio-economic conditions and climate. Current global fire-vegetation models are able to represent the present-day fire activity, but it is unclear how well they can simulate past or future scenarios. Here we use sedimentary charcoal-based biomass burning reconstructions to evaluate fire probability and total carb

Immunofluorescent demonstration of the presence of protein HC on the surface of human lymphocytes

Indirect immunofluorescence was used to demonstrate the presence of protein HC on the surface of a large percentage of normal human peripheral blood lymphocytes. Protein HC is a recently described charge heterogeneous, complex-forming glycoprotein normally present in human plasma, urine and cerebrospinal fluid. The synthesis of protein HC by lymphocytes was indicated by the removal of the glycopro

Serum osteocalcin levels at 4 months of age were associated with neurodevelopment at 4 years of age in term-born children

Aim: The hormone osteocalcin influenced neurodevelopment and cognition in mice models; this human study explored potential associations between total serum levels in human infants and neurodevelopment at 4 years of age. Methods: The data were based on two Swedish birth cohorts from 2008 to 2009. We followed 158 healthy full-term vaginal births (51% girls) by measuring serum osteocalcin in cord blo

Evaluation of an Alternative Learning System for youths at risk of involvement in urban violence in the Philippines

BACKGROUND: Globally, violence disproportionately affects young people, leading to injury, hospitalisation, death, social dysfunction, and poor mental wellbeing. Moreover, it has far-reaching economic consequences for whole nations, due to loss of productivity. Research suggests that attaining a higher level of education promotes factors that insulate youths from poverty and violence.PURPOSE: In t

Reconsidering regional structural conditions for industrial renewal

This article develops a more comprehensive understanding of innovation-based renewal of industries from a structural perspective. Arguably, established perspectives offer rather simplistic views, portraying structures as either enabling or constraining for certain forms of regional industrial change. Inspired by work in organizational institutionalism on ‘institutional infrastructures’, this artic

Trip Reports: Exploring the Experience of Psychedelic Intoxication

Experiences of intoxication elude scientific research because of their immediate and ‘inner’ nature for the intoxicated individual. In this chapter, we show how ‘trip reports’ – reports of psychedelic intoxication – from online drug information forums and libraries allow for further understanding the experience of psychedelic intoxication from LSD, DMT and psilocybin by examining psychonauts’ (i.e

Luminescence of ODC(II) in quartz and cristobalite glasses

The results of the optical spectroscopy of twofold coordinated silicon centers – ODC(II) in quartz and cristobalite glasses are presented. The luminescence and excitation spectra attributed to different local symmetry of ODC(II) were investigated under synchrotron excitation in the VUV region. The observed differences in the luminescence and excitation spectra of ODC(II) are caused by the environmThe results of the optical spectroscopy of twofold coordinated silicon centers – ODC(II) in quartz and cristobalite glasses are presented.

Sensor Networks Tdoa Self-Calibration : 2d Complexity Analysis and Solutions

Given a network of receivers and transmitters, the process of determining their positions from measured pseudoranges is known as network self-calibration. In this paper we consider 2D networks with synchronized receivers but unsynchronized transmitters and the corresponding calibration techniques, known as Time-Difference-Of-Arrival (TDOA) techniques. Despite previous work, TDOA self-calibration i

Selective Monovalent Galectin-8 Ligands Based on 3-Lactoylgalactoside

Galectin-8 has gained attention as a potential new pharmacological target for the treatment of various diseases, including cancer, inflammation, and disorders associated with bone mass reduction. To that end, new molecular probes are needed in order to better understand its role and its functions. Herein we aimed to improve the affinity and target selectivity of a recently published galectin-8 lig

How economic expectations shape preferences for national independence : Evidence from Greenland

This paper investigates how economic expectations shape voting intentions in a hypothetical independence referendum in Greenland, a self-governing region of the Kingdom of Denmark. I identify the causal effect of economic expectations by randomly exposing respondents to a prime informing on Greenland's current fiscal deficit. Respondents exposed to the information are 43% more likely to oppose ind

Location of a novel type of interpolypeptide chain linkage in the human protein HC-IgA complex (HC-IgA) and identification of a heterogeneous chromophore associated with the complex

Protein HC (human complex-forming glycoprotein, heterogeneous in charge) is a member of the lipocalin superfamily of hydrophobic ligand-binding proteins. The quantitatively dominating blood plasma form of protein HC is a protein HC-IgA complex (HC-IgA), which is the fourth most abundant immunoglobulin species in plasma. A photodiode array detection system on-line with a high performance liquid chr

Change in the Th1/Th2 phenotype of memory T-cell clones from rheumatoid arthritis synovium

The stability of established memory T helper (Th)1/Th2 cells in chronic inflammatory diseases is not clear, and a shift of the cytokine balance could control chronic inflammation. In order to study the regulation of the Th phenotype of memory T cells, polyclonal T-cell lines and clones with a Th1, Th0 or Th2 phenotype were developed from rheumatoid synovial tissue. Th1 [interleukin (IL)-12 + anti-

Kinetics of somatic mutation in lymph node germinal centres

Somatic mutation activity in immunoglobulin V kappa genes during the response to the hapten 2-phenyl-5-oxazolone was measured in lymph node B-cell populations at various timepoints after footpad immunization. When the V kappa Ox1 genes rearranged to the J kappa 5 segment were amplified from genomic DNA using the polymerase chain reaction and sequenced, somatic mutations could be detected as early
