Cotton seed trichomes are the most important source of natural fibers globally. The major fiber thickness properties influence the price of the raw material, and the quality of the finished product. The recessive immature fiber (im) gene reduces the degree of fiber cell wall thickening by a process that was previously shown to involve mitochondrial function in allotetraploid Gossypium hirsutum ...

Peste des petits ruminants (PPR) is an acute and highly contagious fatal disease of small ruminants mainly affecting sheep and goats, and camels. PPR is endemic disease in many developing and tropical countries including Pakistan, and vaccine is currently the only means of disease control. However, lack of established infrastructures and high temperature, maintaining cold chain for effective de...

PPR (Pentatricopeptide repeat) proteins are mainly involved in RNA metabolism. In Arabidopsis, the PPR family is composed of more than 450 members; however, only few of them were functionally characterized. In a previous report, ( 1) we identified a novel mitochondrial PPR RNA editing factor, named SLO2, which is responsible for 7 editing events in Arabidopsis. Loss-of-function mutation in SLO...

Mitochondrial synthesis of Cox1, the largest subunit of the cytochrome c oxidase complex, is controlled by Mss51 and Pet309, two mRNA-specific translational activators that act via the COX1 mRNA 5'-UTR through an unknown mechanism. Pet309 belongs to the pentatricopeptide repeat (PPR) protein family, which is involved in RNA metabolism in mitochondria and chloroplasts, and its sequence predicts ...

The aim of this study was to evaluate the effect of a 15% increase in preferred pedal rate (PPR) on both time to exhaustion and pulmonary O(2) uptake (VO(2)) response during heavy exercise. Seven competitive cyclists underwent two constant-power tests (CPT) at a power output that theoretically requires 50% of the difference in VO(2) between the second ventilatory threshold and VO(2)max (Pdelta5...

In the present study, we assessed whether elevated (> or =15 mmHg) PCWP (pulmonary capillary wedge pressure) can be detected using the blood pressure response to the Valsalva manoeuvre in a group of elderly patients with various cardiac disorders, including atrial fibrillation and valvular heart disease, and healthy elderly controls. The Valsalva manoeuvre was performed in 93 patients (71+/-4 y...

Peste des petits ruminants (PPR) and foot-and-mouth disease (FMD) are both highly contagious diseases of small domestic and wild ruminants caused by the PPR virus (PPRV) and the FMD virus (FMDV). In this study, a recombinant PPRV expressing the FMDV VP1 gene (rPPRV/VP1) was generated and FMDV VP1 expression did not impair replication of the recombinant virus in vitro and immunogenicity in induc...

Pentatricopeptide repeat (PPR) proteins function in multiple processes in mRNA maturation in plastids and mitochondria (reviewed in Schmitz-Linneweber and Small, 2008). RNA maturation in chloroplasts is complex, and PPR proteins act in cisand trans-splicing, translation, RNA cleavage, RNA stabilization, and RNA editing. This large protein family, with 450 members in Arabidopsis, is characterize...

Program Perumahan Rakyat (PPR) merupakan satu dasar kerajaan dalam menyeimbangkan keperluan asas tempat tinggal kepada rakyat yang tergolong kategori B40 untuk memelihara hak kemanusiaan Malaysia agar menjalani kelangsungan kehidupan sejahtera. PPR sebagai Key Performance Indicator (KPI) oleh Kementerian dan Kerajaan Tempatan (KPKT) diberi fokus terhadap keberkesanan tahap kesejahteraan PPR. me...

Post Project Reviews (PPRs) are a rich source of knowledge and data for organisations if organisations have the time and resources to analyse them. Too often these reports are stored, unread by many who could benefit from them. PPR reports attempt to document the project experience – both good and bad. If these reports were analysed collectively, they may expose important detail, e.g. recurring...
