Rinderpest (RP) and peste-des-petits-ruminants (PPR) are two important diseases of domestic ruminants. To improve on currently available vaccines against PPR, we have created cDNA copies of the RP virus genome in which either the fusion (F) or hemagglutinin (H) gene, or both, was replaced with the corresponding gene from PPR virus. It was necessary to develop a modified rescue system in which t...

Pentatricopeptide repeat containing proteins (PPRs) bind to RNA transcripts originating from mitochondria and plastids. There are two classes of PPR proteins. The [Formula: see text] class contains tandem [Formula: see text]-type motif sequences, and the [Formula: see text] class contains alternating [Formula: see text], [Formula: see text] and [Formula: see text] type sequences. In this paper,...

Photoparoxysmal response (PPR) is commonly associated with idiopathic generalised epilepsies. Most of the focal events induced by intermittent photic stimulation (IPS) are reported to be of occipital origin. Only six temporal lobe epilepsy patients have been reported in the literature with focal PPR at extraoccipital sites. We report a four-year-old girl with possible encephalitis who presented...

In this paper, we demonstrate the first hybrid suprastructure of pseudopolyrotaxanes (PPRs) on clay nanoplatelets. Simple end-modification of poly(ethylene glycol) with pyridinium (PEG-N(+)) enabled the chains to form brushlike conformation on clay surfaces. Thus, the PEG chains were able to thread into the cavities of α-cyclodextrins (α-CDs), leading to hybrid PPR hydrogels. This was very diff...

Two fault detection approaches are compared using a Projection Pursuit Regression (PPR) algorithm: ia classification approach where the fault detection PPR model is trained based on the class numbers and iian estimation approach where the PPR model is trained to predict the value of the process variable that define the class boundaries and then the corresponding class is identified by comparing...

Pentatricopeptide repeat (PPR) proteins are RNA-binding proteins that are particularly prevalent in terrestrial plants. Although the PPR protein family was only recognized eight years ago, it is already clear that these proteins have a range of essential functions in post-transcriptional processes (including RNA editing, RNA splicing, RNA cleavage and translation) within mitochondria and chloro...

Epidermal growth factor receptor inhibitors (EGFRI) are used for the treatment of advanced colorectal, head and neck, pancreatic, and non-small cell lung cancers. Although EGFRI have a much better tolerability profile compared with conventional cytotoxic drugs, they are associated with significant skin toxicity. The most frequent dermatologic side effect is the papulo-pustular rash (PPR). It of...

INTRODUCTION In plastids and mitochondria of plants, RNA editing changes numerous cytidines to uridines. The nucleotides to be edited are selected by trans-acting proteins which are structurally characterized as pentatricopeptide repeat (PPR) proteins (Kotera et al., 2005; Schmitz-Linneweber and Small, 2008; Takenaka et al., 2013b). The approximately 35 amino acids long elements each attach to ...

Parathyroid hormone (PTH)-related peptide (PTHrP) and the PTH/PTHrP receptor (PPR) play an essential role in controlling growth plate development. The aim of the present study was to use the deer antler as a model to determine whether PTHrP and PPR may also have a function in regulating cartilage and bone regeneration in an adult mammal. Antlers are the only mammalian appendages that are able t...

In Arabidopsis (Arabidopsis thaliana) the 466 pentatricopeptide repeat (PPR) proteins are putative RNA-binding proteins with essential roles in organelles. Roughly half of the PPR proteins form the plant combinatorial and modular protein (PCMP) subfamily, which is land-plant specific. PCMPs exhibit a large and variable tandem repeat of a standard pattern of three PPR variant motifs. The associa...
