Grafting polymerization was a valuable method for the modification of the chemical and physical properties of polymer surfaces. In this paper, the grafting of cationic vinyl monomer with quaternary ammonium groups, methacryloxyethyltrimethyl ammonium chloride (DMC), onto the isotactic polypropylene (iPP) granule was performed by suspension solid-state grafting process. The techniqu...

Chiral insecticide paichongding (IPP) is one of the prospective substitutes for imidacloprid used in China due to its higher activity against imidacloprid-resistant insects. However, little is known about the fate of IPP in soils, including especially the different behaviors among its stereoisomers. In this study, four stereoisomers of IPP were separated and applied in flooded soils. Kinetics o...

PURPOSE To assess the impact of intravesical prostatic protrusion (IPP) on the outcomes of robot-assisted laparoscopic prostatectomy (RALP). MATERIALS AND METHODS The medical records of 1094 men who underwent RALP from January 2007 to March 2013 were analyzed using our database to identify 641 additional men without IPP (non-IPP group). We excluded 259 patients who presented insufficient data...

BACKGROUND The clinical determinants of intraperitoneal pressure (IPP) are ill defined, and the potential impact of elevated IPP on peritoneal dialysis (PD)-related complications is still a matter of debate. We measured IPP in newly started PD patients, assessed its clinical determinants and analysed the incidence of PD-related complications. METHOD IPP was measured in 61 consecutive patients...

BACKGROUND Although interprofessional practice (IPP) offers the potential to enhance rural health services and provide support to rural clinicians, IPP may itself be problematic due to workforce limitations and service fragmentation. Differing socioeconomic and geographic characteristics of rural communities means that the way that IPP occurs in rural contexts will necessarily differ from that ...

A mutant line of BHK21 cells lacking inosinic pyrophosphorylase activity (IPP~ cells) does not incorporate [*H]hypoxanthine, as opposed to wild type BHK cells. When IPP+ and IPP~ cells are grown together in the presence of [H]hypoxanthine, IPP~ cells in contact with IPP+ cells incorporate the marker, as seen by autoradiography. This phenomenon is known as 'metabolic co-operation'. In the presen...

STUDY DESIGN Intraparenchymal pressure (IPP) measurements in an in vitro cadaveric model of CNS edema. OBJECTIVE To assess the contribution of pia mater to IPP and the effect of piotomy. SUMMARY OF BACKGROUND DATA Multicenter randomized control trials have shown that decompression with durotomy/duroplasty significantly decreases intracranial pressure (ICP). There is a paucity of evidence re...

INTRODUCTION The objective of this study is to determine the relationships between prostatic volume (PV) and intravesical prostatic protrusion (IPP) with benign prostatic obstruction (BPO). MATERIALS AND METHODS A total of 408 males (aged 50 years and above) who presented with lower urinary tract symptoms (LUTS) suggestive of benign prostatic hyperplasia (BPH) were recruited. All had Internat...

BACKGROUND In automated peritoneal dialysis (APD) one of the most important factors that influence the efficiency of the treatment is the total volume of dialysate infused per session and the dwell time. This study is aimed at examining the relationships between i.p. pressure (IPP), dialysate flow characteristics, and different dialysate fill volumes in order to optimize APD. METHODS We studi...
