Preeclampsia is a major cause of perinatal mortality and disease affecting 5-10% of all pregnancies worldwide, but its etiology remains poorly understood despite considerable research effort. Parent-offspring conflict theory suggests that such hypertensive disorders of pregnancy may have evolved through the ability of fetal genes to increase maternal blood pressure as this enhances general nutr...

Axonemal dyneins are preassembled in the cytoplasm before being transported into cilia and flagella. Recently, PF13/KTU, a conserved protein containing a PIH (protein interacting with HSP90) domain, was identified as a protein responsible for dynein preassembly in humans and Chlamydomonas reinhardtii. This protein is involved in the preassembly of outer arm dynein and some inner arm dyneins, po...

Di-2-pyridylketone 4,4-dimethyl-3-thiosemicarbazone (Dp44mT) demonstrates potent anti-cancer activity. We previously demonstrated that 14C-Dp44mT enters and targets cells through a carrier/receptor-mediated uptake process. Despite structural similarity, 2-benzoylpyridine 4-ethyl-3-thiosemicarbazone (Bp4eT) and pyridoxal isonicotinoyl hydrazone (PIH) enter cells via passive diffusion. Considerin...

BACKGROUND The treatment of post-inflammatory hyperpigmentation (PIH) remains challenging. Tranexamic acid, a well-known anti-fibrinolytic drug, has recently demonstrated a curative effect towards melasma and ultraviolet-induced PIH in Asian countries. However, the precise mechanism of its inhibitory effect on melanogenesis is not fully understood. OBJECTIVE In order to clarify the inhibitory...

Pregnancy-induced hypertension (PIH, including preeclampsia [PE] and gestational hypertension [GH]) and cardiovascular diseases (CVDs) have some metabolic changes and risk factors in common. Many studies have reported associations between single nucleotide polymorphisms (SNPs) of renin-angiotensin-aldosterone system (RAAS) genes and CVDs (particularly hypertension), and their findings have prov...

Recent studies showed that gallium and iron uptake are decreased in gallium-resistant (R) CCRF-CEM cells; however, the mechanisms involved were not fully elucidated. In the present study, we compared the cellular uptake of 59Fe-transferrin (Tf) and 59Fe-pyridoxal isonicotinoyl hydrazone (PIH) to determine whether the decrease in iron uptake by R cells is caused by changes in Tf receptor (TfR)-d...

OBJECTIVE To compare cord blood leptin concentrations between normal pregnancy, pregnancy induced hypertension (PIH), and gestational diabetes mellitus (GDM). DESIGN Cross-sectional study. SETTING Academic institutes and a tertiary care maternal hospital. METHOD 48 newborns of normal pregnancies (N=18), pregnancy induced hypertension (N=16), and gestational diabetes mellitus (N=14) were s...

A major obstacle to the therapeutic use of anthracyclines, highly effective anticancer agents, is the fact that their administration results in dose-dependent cardiomyopathy. According to the currently accepted hypothesis, anthracyclines injure the heart by generating oxygen free radicals. The ability of pyridoxal isonicotinoyl hydrazone (PIH) and salicylaldehyde isonicotinoyl hydrazone (SIH) -...

Background: The term "pregnancy-induced hypertension," or PIH, refers to a pattern of elevated blood pressure that appears during woman's pregnancy. It is one the most important factors contributing maternal mortality rate and infant morbidity worldwide. In addition its impacts, this risk can be decreased by transmission health education emphasises early identification appropriate treatment dis...
