Background: To investigate difference in intratesticular arterial pulsatility index (PI) and resistance index (RI) between varicocele and healthy testes using power Doppler ultrasonography. Materials and Methods: Patients undergoing scrotal ultrasonography were recruited. PI and RI of the intratesticular artery were measured using a 12-MHz power Doppler ultrasound, and varicocele grades were ob...
Heavy metal contamination of minesoils is a widespread problem in China. In Pingle manganese mineland in Guangxi (south China), heavy metal concentrations in soils and dominant plants were determined, and soil contamination was assessed with pollution index (Pi) and index of geoaccumulation (I-geo). Pi showed the minesoil was heavily polluted by Cd and slightly polluted by Cr. I-geo showed a se...
Background: Multiple sclerosis (MS) is an inflammatory disease of the central nervous system with multifocal areas of demyelination. Despite an increased understanding of the mechanisms causing MS, immunological factors that indicate disease activity are only starting to be discovered. Chronic brain inflammation is often associated with an increase in production of IgG in the CSF as determined ...
Aims—To investigate the relation between changes in splanchnic arterial haemodynamics and renal arterial haemodynamics in controls and patients with cirrhosis. Methods—Superior mesenteric artery pulsatility index (SMA-PI) and renal artery pulsatility index (R-PI) were measured using Doppler ultrasonography in 24 controls and 36 patients with cirrhosis. These measurements were repeated 30 minute...
AIMS To investigate the relation between changes in splanchnic arterial haemodynamics and renal arterial haemodynamics in controls and patients with cirrhosis.

BACKGROUND The proliferative index (PI) is a powerful prognostic factor in mantle cell lymphoma (MCL); however, its utility is hampered by interobserver variability. The mantle cell international prognostic index (MIPI) has been reported to have prognostic importance. In this study, we determined the prognostic value of the PI as determined by quantitative image analysis in MCL. PATIENTS AND ...
Background and Aim: Cyclosporine-A (CsA) is commonly prescribed for kidney transplant patients to suppress their immune systems, which can lead to gingival enlargement (GE) . The present study aimed at determining the prevalence of associated factors with CsA-induced gingival enlargement in kidney transplant patients in Rasht during 2012. Materials and Methods: In this cross sectional research,...
In this paper, we present some inequalities for the Co-PI index involving the some topological indices, the number of vertices and edges, and the maximum degree. After that, we give a result for trees. In addition, we give some inequalities for the largest eigenvalue of the Co-PI matrix of G.
conclusions: in this study, kidney transplant recipients with a lower ri and pi and a higher edv at 1week showed better graft function at 6 months after transplantation. results: fourteen patients (15.4%) had impaired graft function after 6 months (gfr less than 60 ml/min/1.73m2). multivariate linear regression analysis showed significant correlation between gfr at 6 months and ri, pi and edv w...
OBJECTIVES To investigate the optimal definition of abnormal first-trimester uterine artery Doppler parameters associated with adverse pregnancy outcomes. METHODS A prospective cohort of women with singleton gestations between 11 and 14 weeks consented to uterine artery Doppler measurements. Doppler parameters were measured bilaterally, and mean pulsatility index (PI) and resistive index (RI)...
