Chloroplast gene expression is mainly regulated at the post-transcriptional level by numerous nuclear-encoded RNA-binding protein factors. In the present study, we focus on two RNA-binding proteins: cpRNP (chloroplast ribonucleoprotein) and PPR (pentatricopeptide repeat) protein. These are suggested to be major contributors to chloroplast RNA metabolism. Tobacco cpRNPs are composed of five diff...

Parathyroid hormone (PTH)-related protein (PTH-rP) is an important autocrine/paracrine attenuator of programmed cell differentiation whose expression is restricted to the epithelial layer in tooth development. The PTH/PTHrP receptor (PPR) mRNA in contrast is detected in the dental papilla, suggesting that PTHrP and the PPR may modulate epithelial-mesenchymal interactions. To explore the possibl...

Aim The aim of this study was to investigate the seroprevalence of antibodies against foot and mouth disease (FMD), Peste des Petits ruminants (PPR), and bluetongue (BT) in sheep and goats within Giza and Beni-Suef governorates at the second half of 2016. Materials and Methods A total of 300 animals (sheep and goats) randomly selected from small stocks with no history of previous vaccination ...

BACKGROUND Peste des petits ruminants (PPR) is an acute infectious viral disease affecting domestic small ruminants (sheep and goats) and some wild ruminant species in Africa, the Middle East and Asia. A global PPR control strategy based on mass vaccination-in regions where PPR is endemic-was recently designed and launched by international organizations. Sahelian Africa is one of the most chall...

Clinically, peste des petits ruminants (PPR) is characterized by erosive stomatitis, enteritis with diarrohea and pneumonia. The outbreaks of a rinderpest like disease later confirmed by World Reference Laboratory to be PPR have been occurring in goats since 1993 in Bangladesh and found that the virus has a close relation with the Indian isolates (West Bengal) of PPRV at a cluster with Asian gr...

To define prognostic factors in infant acute lymphoblastic leukemia (ALL), the outcome of 106 infants (age </=12 months) during 3 consecutive multicenter trials of the Berlin-Frankfurt-Münster group (ALL-BFM 83, 86, and 90) was retrospectively analyzed according to presenting features and early in vivo response to prednisone. The prednisone response was defined as the cytoreduction (number of b...

Superconvergence of order O(h), for some ρ > 0, is established for the gradient recovered with the Polynomial Preserving Recovery (PPR) when the mesh is mildly structured. Consequently, the PPR-recovered gradient can be used in building an asymptotically exact a posteriori error estimator.

Recent identification of several different types of RNA editing factors in plant organelles suggests complex RNA editosomes within which each factor has a different task. However, the precise protein interactions between the different editing factors are still poorly understood. In this paper, we show that the E+-type pentatricopeptide repeat (PPR) protein SLO2, which lacks a C-terminal cytidin...

Pentatricopeptide repeat (PPR) proteins are a large family of helical-repeat proteins that bind RNA in mitochondria and chloroplasts. Precise RNA targets and functions have been assigned to only a small fraction of the >400 members of the PPR family in plants. We used the amino acid code governing the specificity of RNA binding by PPR repeats to infer candidate-binding sites for the maize prote...

BACKGROUND AND OBJECTIVES Periprosthetic aortic regurgitation (PPR) after transcatheter aortic valve implantation (TAVI) remains an important issue associated with impaired long-term outcomes. The current randomised study aims to evaluate potential differences between the balloon-expandable Edwards SAPIEN-3 and the self-expanding Medtronic CoreValve system with the main focus on post-TAVI PPR b...
