Ancient and modern 183 varieties of winter 23 spring types development bread wheat (Triticum aestivum L.) selected Ukrainian state institutions private companies are characterized by alleles Ppd-D1, Ppd-B1, Ppd-A1 genes. Allele-specific molecular markers, proposed in the scientific literature, were used to identify carriers Ppd-D1a, Ppd-D1b, Ppd-D1c, Ppd-D1d, Ppd-B1a, Ppd-B1c, Ppd-A1b alleles. ...

BACKGROUND Being a contact allergen of general relevance, p-phenylenediamine (PPD) is patch tested in the baseline series. However, PPD 1% in petrolatum may actively sensitize. Patch testing with PPD at 0.35% pet. proved to be safe, as far as active sensitization is concerned. OBJECTIVES To determine whether PPD 0.3% pet. reliably detects PPD sensitization. METHODS Patch testing with PPD 0....

BACKGROUND 20(S)-protopanaxadiol (PPD), similar to several other anticancer agents, has low oral absorption and is extensively metabolized. These factors limit the use of PPD for treatment of human diseases. METHODS In this study, we used cubic nanoparticles containing piperine to improve the oral bioavailability of PPD and to enhance its absorption and inhibit its metabolism. Cubic nanoparti...

BACKGROUND The factors influencing elicitation responses in individuals allergic to p-phenylenediamine (PPD) in hair dyes are not well understood. OBJECTIVES Investigation of the elicitation response to the new, less-sensitizing PPD alternative 2-methoxymethyl-p-phenylenediamine (ME-PPD) under simulated hair dye use conditions. METHODS The cross-elicitation response to ME-PPD (2% in a hair ...

Background Postpartum depression (PPD) poses a major global public health challenge. PPD is the most common complication associated with childbirth and exerts harmful effects on children. Although hundreds of PPD studies have been published, we lack accurate global or national PPD prevalence estimates and have no clear account of why PPD appears to vary so dramatically between nations. Accordin...

An ultra-performance liquid chromatography-electrospray tandem mass spectrometry (UPLC-ESI-MS/MS) method was developed to investigate 20(S)-protopanaxadiol (PPD) pharmacokinetics in rats. Rat plasma samples were treated using a solid-phase extraction with satisfactory recovery (> 81%). The method showed an excellent sensitivity that the limit of detection (LOD) and the lower limit of quantitati...

20(S)-Protopanaxadiol (PPD), a bioactive compound extracted from ginseng, possesses cardioprotective, neuroprotective, anti-inflammatory, antiestrogenic, anticancer and anxiolytic effects. However, the clinical application of PPD is limited by its weak aqueous solubility. In this study, we optimized an efficient method of preparing its phospholipid complex (PPD-PLC) using a central composite de...

Flowering time in wheat and barley is known to be modified by mutations in the Photoperiod-1 (Ppd-1) gene. Semi-dominant Ppd-1a mutations conferring an early flowering phenotype are well documented in wheat but gene sequencing has also identified candidate loss of function mutations for Ppd-A1 and Ppd-D1. By analogy to the recessive ppd-H1 mutation in barley, loss of function mutations in wheat...

CorA is a primary Mg2+ transporter in bacteria, which also mediates influx of Ni2+ and Co2+. Topological studies suggested that it could be divided into a large soluble periplasmic domain (PPD) and three membrane-spanning alpha-helixes. In the present study, glutathione S-transferase (GST) fusion Escherichia coli CorA PPD was purified by GST affinity chromatography, and PPD was obtained by on-c...

The effect of the major flowering gene (PPD) on seed weight of chickpea was studied on 450 F3 families from reciprocal crosses between a small-seeded, early-flowering (ppd/ppd ) type and a largeseeded, late flowering (PPD/PPD) cultivar. F4 progeny tests were carried out to determine the PPD genotypes of each individual F3. The effects of the PPD gene and the polygenes on mean seed weight were b...
