OBJECTIVE The current study was designed to evaluate the sensitivity, feasibility, and effectiveness of the pallidal index (PI) serving as a biomarker of brain manganese (Mn) accumulation, which would be used as an early diagnosis criteria for Mn neurotoxicity. METHODS The weighted mean difference (WMD) of the PI between control and Mn-exposed groups was estimated by using a random-effects or...

Although color Doppler ultrasonography has been used to evaluate testicular blood flow in many species, very little has been done in goat. Eight male Shiba goats were exposed to a single intramuscular injection of either gonadotropin-releasing hormone (GnRH group; 1 µg/kg BW) or human chorionic gonadotropin (hCG group; 25 IU/kg BW). Plasma testosterone (T), estradiol (E2) and inhibin (INH) were...

Deep hypothermic circulatory arrest (DHCA) with retrograde cerebral perfusion (RCP) under high central venous pressure (CVP) is often used in aortic arch surgery under cardiopulmonary bypass (CPB). We hypothesized that DHCA with RCP under high CVP causes cerebral vascular compression because of increased perivascular pressure due to extravasation of fluid into intracranial tissue. In a retrospe...

INTRODUCTION Doppler ultrasonography (DU) is mostly used for assessment of both graft and native kidneys' vascular status. In this study, correlation between the DU indexes and kidney allograft function was evaluated. MATERIALS AND METHODS Hospital records of 273 kidney transplant patients (154 men and 119 women) were reviewed. In all cases, DU had been performed 1 month after kidney transpla...

OBJECTIVE The aim of this study was to evaluate the foetal renal blood flow with colour Doppler ultrasonography. Patients with polyhydramnios were investigated for the foetal renal artery pulsatility index (PI) at the beginning of the treatment, and after the conservative treatment in those who reached the normal amniotic fluid index. MATERIALS AND METHODS In this prospective study, 39 foetus...

interleukin-1β (il-1β) is one of the most important cytokines which seems to have an important role in the inflammatory process in gingival and peri-implant tissues. the aim of this split-mouth study was to investigate the relationship between the concentration of il-1β in gingival crevicular fluid (gcf) and peri-implant crevicular fluid (picf) and clinical parameters such as plaque index (pi),...

background: chronic renal failure patients undergoing hemodialysis are susceptible to periodontal diseases due to systemic complications of the disease and using different drugs. the present study investigated the periodontal status of patient’s who underwent hemodialysis, in babol, northern iran. methods: one-hundred-fifteen hemodialysis patients (63 males, 52 females) with the mean age of 47....

structural codes vis-a-vis structural counts, like polynomials of a molecular graph, areimportant in computing graph-theoretical descriptors which are commonly known astopological indices. these indices are most important for characterizing carbon nanotubes(cnts). in this paper we have computed sadhana index (sd) for phenylenes and theirhexagonal squeezes using structural codes (counts). sadhan...

OBJECTIVE To construct monochorionic diamniotic (MCDA) and dichorionic diamniotic (DCDA) twin reference ranges for umbilical artery (UA) pulsatility index (PI), UA resistance index (RI), fetal middle cerebral artery (MCA) PI and peak systolic velocity (PSV) and cerebroplacental ratio (CPR) from 24 weeks' to 38 weeks' gestation and compare these with published normal values for singleton pregnan...
