Recent evidence suggests that emotional picture-viewing is a reliable method of engaging descending modulation of spinal nociception. The present study attempted to replicate these findings and determine the effect of noxious stimulus predictability. Participants viewed pictures from the International Affective Picture System (IAPS), during which pain and nociceptive flexion reflexes (NFR) were...

The present study examined whether a moderately aversive abdominal threat would lead to greater enhancement in affect- and pain-related defensive responding as indexed by the acoustic startle reflex (ASR) and nociceptive flexion reflex (NFR) in women compared to men. We also predicted sex differences in threat-related autonomic arousal measured by skin conductance responses (SCRs) to acoustic s...

Nucleosome depletion at transcription start sites (TSS) has been documented genome-wide in multiple eukaryotic organisms. However, the mechanisms that mediate this nucleosome depletion and its functional impact on transcription remain largely unknown. We have studied these issues at human MHC class II (MHCII) genes. Activation-induced nucleosome free regions (NFR) encompassing the TSS were obse...

BACKGROUND Nucleosome free regions (NFRs) play important roles in diverse biological processes including gene regulation. A genome-wide quantitative portrait of each individual NFR, with their starting and ending positions, lengths, and degrees of nucleosome depletion is critical for revealing the heterogeneity of gene regulation and chromatin organization. By averaging nucleosome occupancy lev...

UNLABELLED Slow breathing is used as a means to reduce pain, yet the mechanisms responsible for respiration-induced hypoalgesia are poorly understood. The present study asked 30 healthy participants (M(age) = 21 years, M(education) = 15 years, 80% white non-Hispanic) to breathe at normal, slow (50% normal), and fast (125% normal) rates while constant-intensity, suprathreshold electric stimulati...

The kinetics of oxidation of rainbow trout (Oncorhynchus mykiss) NADPH-cytochrome P450 reductase (NCPR) by cytochrome-c and NADH-ferricyanide reductase (NFR) by K3Fe(CN)6 were studied. NCPR and NFR activities from liver microsomes of rainbow trout (Oncorhynchus mykiss) had a specific activity of 0.0246 and 0.0350 nmoles/min/mg protein, respectively. The maximal rate of NCPR reaction was found a...

Abstract Objective The role of the brain in endurance performance is frequently debated; surprisingly, few investigations have attempted to improve by directly targeting activity. One promising but untested approach modifying activity electroencephalogram (EEG) neurofeedback. Consequently, our experiment first examine an EEG neurofeedback intervention for whole-body performance. Method We adopt...

Abstract This study builds on the expanding literature interplay of corporate governance and environment behaviour following introduction carbon reporting directives UK Companies Act in 2013. We specifically focus seeking clarity relationship between gender diversity, board independence, size with environmental performance. The examines these relationships under a mandatory nonfinancial (NFR) r...

Non-Functional Requirements (NFR) are subjective, interactive and relative, thus realizing the need for particular NFR is by itself a challenge. Furthermore understanding what the software must implement in order to cope with these needs may prove to be an even more challenging task. One way of addressing the need for help on NFR elicitation is the use of catalogues. However, it is not clear ho...

The course of ageing leads to various changes in the nervous system, which can affect pain processing in the elderly. However, the affection of different components of the nociceptive system remains unclear. To investigate basic nocifensive responses, we compared age-related changes of autonomic and motor reflex responses to noxious electrical stimulation. In 39 healthy young subjects (mean +/-...
