PAIRED (PRD)-like homeobox genes belong to a class of predicted transcription factor genes. Several of these PRD-like homeobox genes have been predicted in silico from genomic sequence but until recently had no evidence of transcript expression. We found recently that nine PRD-like homeobox genes, ARGFX, CPHX1, CPHX2, DPRX, DUXA, DUXB, NOBOX, TPRX1 and TPRX2, were expressed in human preimplanta...

Partial root drying (PRD) is a new irrigation and plants growing technique which improves water use efficiency without significant yield reduction. In the present paper some of the recent data concerning PRD effects on crop plants are presented as well as some of our own results of PRD grown tomato plants. Tomato plants (Lycopersicon esculentum Mill.) were grown in commercial compost with the r...

Pax proteins are transcriptional regulators controlling a variety of cell fates during animal development. This role depends on the intact function of the paired (Prd) domain that is able to recognize specific DNA sequences. The Prd domain is composed of two distinct helix-turn-helix subdomains, PAI and RED. Molecular functions of Pax proteins are subjected to different levels of regulation inv...

This chapter presents the Late Quaternary neo-tectonic movement in the Pearl River Delta (PRD) region of China and its effects on the coastal sedimentary environment. Taking the Xilin Hill fault as the example, we have explained the reason of the PRD formation, inferred its interactions with local/regional climate and sea-level changes, and analyzed the evolution of the PRD formation and its co...

To investigate effects of soil moisture heterogeneity on plant physiology and gene expression in roots and leaves, three treatments were implemented in sunflower plants growing with roots split between two compartments: a control (C) treatment supplying 100% of plant evapotranspiration, and two treatments receiving 50% of plant evapotranspiration, either evenly distributed to both compartments ...

The objective of this study was to develop simple, precise, accurate, reproducible and economical vireodt's method for simultaneous estimation of mesalamine (MSM) and prednisolone (PRD) in combined oral dosage form. The method involved measurement of absorbance at two wavelengths, 332nm and 246nm, λmax of MSM and PRD, respectively in phosphate buffer (pH 7.4) with dimethyl formamide (DMF) as co...

awareness of the effects of water deficit on quality and quantity yield of orange is essential for product managing at water shortage conditions. in this regard, present study was conducted in an orange garden of babol area in 2011 in a completely randomized design with 5 treatments and 5 replications. experiment treatments included full irrigation (fi), regulated deficit irrigation (rdi) and p...

Phosphatidylinositol-3 kinase-related kinases (PIKKs) comprise a family of protein kinases that respond to various stresses, including DNA damage, blocks in DNA replication, availability of nutrients and errors in mRNA splicing. PIKKs are characterized by the presence of a conserved kinase domain (KD), whose activity is regulated by two C-terminal regions, referred to as PIKK-regulatory domain ...

High order sliding mode controller (HOSMC) is proposed for blood glucose regulation. With this aim a novel concept of Practical Relative Degree (PRD) and a method of its identification are suggested. First, for PRD identification method is applied for the most simple (Bergman Minimal Model) and the most complicated (Sorensen Model) models concluding that the common PRD for both models is three....

This study examines whether subgroups of Black youth exist based on the presence or absence of racial discrimination experiences in the school context and whether these groups varied by gender and household income. Latent transition analyses were performed on racial discrimination indicators derived when youth were in the 8th and 11th grades. Three distinct subgroups of youth emerged. Youth in ...
