The lateral spiriform nucleus (SpL) in the chick mesencephalon contains functional nicotinic receptors and receives a cholinergic fiber projection. We now use double-label immunohistochemistry to demonstrate that choline acetyltransferase-immunopositive fibers in the SpL and in the cholinergic fiber tract lateral to the nucleus are associated with fibers expressing the alpha5 and/or alpha3 nico...

Cell-cell interactions mediated by the Notch receptor play an essential role in the development of the Drosophila adult peripheral nervous system (PNS). Transcriptional activation of multiple genes of the Enhancer of split Complex [E(spl)-C] is a key intracellular response to Notch receptor activity. Here we report that most E(spl)-C genes contain a novel sequence motif, the K box (TGTGAT), in ...

BACKGROUND Supernumerary phantom limb (SPL) is a rare neurologic phenomenon, in which a patient misperceives an extra limb in addition to the original set of limbs. We report a case of SPL in a patient with a right basal ganglia hemorrhage and review the previous literature about this peculiar phenomenon. CASE PRESENTATION Two days after the event of a right basal ganglia hemorrhage, a 78-yea...

Six-month-old infants have been found to respond differentially to sounding objects placed within reach and beyond reach when no visual cues were available. The goal of the present study was to investigate whether sound-pressure level (SPL) serves as an auditory cue in distance discrimination. Thirty-two 6-month-olds were presented with recordings of sounding objects first in the light at midli...

Objective: We compared the stretched penile length (SPL) in hypospadias with SPL-for-age nomogram and studied the penile growth after chordee correction in proximal hypospadias. Methods: It was a cross-sectional study from April to September 2013. Hundred pre-operative hypospadias patients upto 10 years age underwent SPL measurement for comparison with nomogram. Hypospadias severity was recorde...

Family-based (lifted) data-flow analysis for Software Product Lines (SPLs) is capable of analyzing all valid products (variants) without generating any of them explicitly. It takes as input only the common code base, which encodes all variants of a SPL, and produces analysis results corresponding to all variants. However, the computational cost of the lifted analysis still depends inherently on...

Sphingosine 1-phosphate (S1P) is a bioactive lipid molecule that acts both extracellularly and intracellularly. The SPL gene encodes a mammalian S1P lyase that degrades S1P. Here, we have disrupted the SPL gene in mouse F9 embryonal carcinoma cells by gene targeting. This is the first report of gene disruption of mammalian S1P lyase. The SPL-null cells exhibited no S1P lyase activity, and intra...

The posterior field (P) of the cat auditory cortex contains a very high proportion of neurons whose responses change non-monotonically with the sound pressure level (SPL) of tonal stimuli, leading to circumscribed frequency-SPL response areas, and it has therefore been suggested that field P may be specialized for processing of sound intensity. We demonstrate here a great diversity of response ...

Helix-loop-helix proteins play important roles in developmental processes, such as myogenesis, neurogenesis, and sex determination. The gene Enhancer of split [E(spl)] of Drosophila, a member of a gene complex that is involved in early neurogenesis, encodes a protein with a basic domain and a helix-loop-helix motif. We took advantage of a dominant mutation of this gene, E(spl)D, to define in vi...

We identified the interaction sites of several miRNAs with the mRNAs from paralogs and orthologs of the SPL and HAM genes in A. thaliana. miRNAs from the miR156 and miR157 families in A. thaliana are shown to have binding sites within the mRNAs of SPL genes. The ath-miR156a-j binding sites located in the mRNAs of the SPL paralogs contain the sequence GUGCUCUCUCUCUUCUGUCA. This sequence encodes ...
