Peste des petits ruminants (PPR) is a highly contagious and economically important disease of small ruminants caused by a virus in the genus morbillivirus, family paramyxoviridae. This infection is responsible for high morbidity and mortality. In this study, an outbreak of PPR in goats was investigated in a well organized farm at district Lahore. Clinical signs, gross lesions and histopathologi...

Pentatricopeptide repeat (PPR) proteins form a huge family in plants (450 members in Arabidopsis and 477 in rice) defined by tandem repetitions of characteristic sequence motifs. Some of these proteins have been shown to play a role in posttranscriptional processes within organelles, and they are thought to be sequence-specific RNA-binding proteins. The origins of this family are obscure as the...

Aim: The present study was planned with an aim to access the incidence of Peste des petits ruminants (PPR) in nomadic sheep and goat of Jammu region of Jammu and Kashmir (J&K) state of India. Materials and Methods:A total of 34 nasal swabs (13 sheep and 21 goats) samples of 13 flocks suspected for PPR infection were screened for presence of PPR virus antigen by PPR sandwich-ELISA kit. Results: ...

BACKGROUND Preprogrammed reactions (PPR) appear at a latency of higher than 40 ms, but before the voluntary muscle responds (approximately 120 ms) to postural perturbations. OBJECTIVE To examine the difference in magnitude of preprogrammed reactions in patients with chronic low back pain (CLBP) and without low back pain. METHODS we analyzed electromyographic Root Mean Square (RMS) amplitude...

The hepatitis E virus (HEV) polyproline region (PPR) is an intrinsically unstructured region (IDR). This relaxed structure allows IDRs, which are implicated in the regulation of transcription and translation, to bind multiple ligands. Originally the nucleotide variability seen in the HEV PPR was assumed to be due to high rates of insertion and deletion. This study shows that the mutation rate i...

The pentatricopeptide repeat (PPR) protein family is highly expanded in terrestrial plants. Arabidopsis contains 450 PPR genes, which represents 2% of the total protein-coding genes. PPR proteins are eukaryote-specific RNA-binding proteins implicated in multiple aspects of RNA metabolism of organellar genes. Most PPR proteins affect a single or small subset of gene(s), acting in a gene-specific...

Pentatricopeptide repeat proteins are one of the major protein families in flowering plants, containing around 450 members. They participate in RNA editing and are related to plant growth, development and reproduction, as well as to responses to ABA and abiotic stresses. Their characteristics have been described in silico; however, relatively little is known about their biochemical properties. ...

A novel, to our knowledge, in situ photoirradiation system for solid-state NMR measurements is improved and demonstrated to successfully identify the M-photointermediate of pharaonis phoborhodopsin (ppR or sensory rhodopsin II), that of the complex with transducer (ppR/pHtrII), and T204A mutant embedded in a model membrane. The (13)C NMR signals from [20-(13)C]retinal-ppR and ppR/pHtrII reveale...
