We examined the responses of neurons in the parietal reach region (PRR) during reaches to the remembered locations of auditory or visual stimuli. We found that the firing rate of PRR neurons contained information about the location of auditory and visual stimuli. For neurons tested with visual stimuli, the amount of information remained constant throughout the task. In contrast, for neurons tes...
Packet reception rate (PRR) and energy consumption are two important metrics when designing a wireless body area network (WBAN). Due to posture changes and influences from the environment, the wireless links in WBANs have a relatively low quality that varies over time. Due to the limited size of wireless body sensors and their power supply, energy consumption should be as small as possible. Thi...
A current challenge of cell biology is to investigate molecular interactions in subcellular compartments of living cells to overcome the artificial character of in vitro studies. To dissect the interaction of the neuronal microtubule (MT)-associated protein tau with MTs in axon-like processes, we used a refined fluorescence decay after photoactivation approach and single-molecule tracking. We f...
BACKGROUND Using a multi-methods approach we aimed to explore the relative prediction of demographic, socioeconomic and modifiable predictors from the Theory of Planned behaviour (TPB) in explaining feeding intentions amongst a multi-ethnic sample. METHODS 476 women completed a questionnaire at 28 weeks gestation. They were grouped into breastfeeding (N = 258), mixed-feeding (N = 50), bottle-...
Anticodon loop cleavages of two host tRNA species occur in bacteriophage T4-infected Escherichia coli CTr5X, a host strain restricting phage mutants deficient in polynucleotide kinase (pnk) or RNA ligase (rli). The cleavage products accumulate with the mutants but are further processed in wt infection through polynucleotide kinase and RNA ligase reactions. Inactivating mutations in stp suppress...
Plasmacytoid Dendritic Cells (pDCs) represent a key immune cell population in the defense against viruses. pDCs detect viral pathogen associated molecular patterns (PAMPs) through pattern recognition receptors (PRR). PRR/PAMP interactions trigger signaling events that induce interferon (IFN) production to initiate local and systemic responses. pDCs produce Type I and Type III (IFNL) IFNs in res...
Upon chronic microbial exposure and pattern-recognition receptor (PRR) stimulation, myeloid-derived cells undergo a distinct transcriptional program relative to acute PRR stimulation, with proinflammatory pathways being downregulated. However, other host-response pathways might be differentially regulated, and this concept has been relatively unexplored. Understanding mechanisms regulating chro...
To explore definitions for multisite pain, and compare associations with risk factors for different patterns of musculoskeletal pain, we analysed cross-sectional data from the Cultural and Psychosocial Influences on Disability (CUPID) study. The study sample comprised 12,410 adults aged 20-59 years from 47 occupational groups in 18 countries. A standardised questionnaire was used to collect inf...
Proton and oxygen-17 NMR relaxation rate (T1-1 and T2-1) data are presented for aqueous suspensions of dark-adapted chloroplasts. It is concluded from the dependence of the proton relaxation rates (PRR) upon Mn concentration that T1-1 and T2-1 are determined largely by the loosely bound Mn present in the chloroplast membranes. The frequency and temperature dependences of PRR are characteristic ...
A gain field, the scaling of a tuned neuronal response by a postural signal, may help support neuronal computation. Here, we characterize eye and hand position gain fields in the parietal reach region (PRR). Eye and hand gain fields in individual PRR neurons are similar in magnitude but opposite in sign to one another. This systematic arrangement produces a compound gain field that is proportio...
