20(S)-Protopanaxadiol (PPD), a ginsenoside isolated from Pananx quinquefolium L., has been shown to inhibit growth and proliferation in several cancer cell lines. The aim of this study was to evaluate its anticancer activity in human breast cancer cells. MCF-7 cells were incubated with different concentrations of 20(S)-PPD and cytotoxicity was evaluated by MTT assay. Occurrence of apoptosis was...

Wheat landraces carry abundant genetic variation in heading and flowering times. Here, we studied flowering-related traits of two Nepalese varieties, KU-4770 and KU-180 and a Japanese wheat cultivar, Shiroganekomugi (SGK). These three wheat varieties showed similar flowering time in a common garden experiment. In total, five significant quantitative trait loci (QTLs) for three examined traits, ...

Intradermal test (IDT) was used as an official diagnosis of bovine tuberculosis (bTB), mainly caused by Mycobacterium bovis. Test-and-slaughter policy was implemented by many countries for control of bTB due to human health as well as, the health of cattle. Purified protein derivative (PPD) was used as IDT diagnostics, which is the native protein complex from culture supernatant of M. bovis. Ho...

A kinematic approach was used to measure mother-infant spatial proximity at 4 months. Maternal postpartum depression (PPD) impacts on mother-infant spatial interaction. We compared 28 dyads with mothers meeting criteria for PPD and 46 typical dyads. The PPD dyads had less variability in spatial proximity compared to typical dyads.

OBJECTIVE To evaluate the impact of patent ductus arteriosus (PDA) on the pulse phase difference (PPD) between the left foot (postductal region) and the right hand (preductal region). MATERIALS AND METHODS PPD was determined from arterial photoplethysmography signals (pulse waves) measured by infrared sensors routinely used for pulse oximetry in 56 premature infants less than 32 weeks gestati...

Objective: Among mothers with recent births, we identify the effects of self-reported stressful life events in the year before delivery on the risk of postpartum depression (PPD). Methods: Survey data (1997-1998) from the North Carolina Pregnancy Risk Assessment Monitoring System (PRAMS) were used to evaluate the impact of both the quantity of stress and individual stressors on the risk of PPD....

BACKGROUND Postpartum depression (PPD) is moderate to severe depression in a woman after she has given birth. Findings from several well-designed studies reflect great variability in rates, from 10 to 22%, and also in risk factors for PPD. This variability may reflect geographical location. The incidence and risk factors for PPD among Turkish women are not well documented. It is, however, impor...

Postpartum depression (PPD) is a disorder of multifactorial origin with significant consequences on both maternal and child health. One of the biological factors implicated is perturbed methionine-homocysteine metabolism. Since this metabolic pathway plays a significant role in myelination of nerve fibers, the growth and development of the child would also be adversely affected. We carried out ...

INTRODUCTION With approximately 4 million births each year in the United States, an estimated 760,000 women annually suffer from a clinically significant postpartum depressive illness. Yet even though the relationship between psychiatric disorders and the postpartum period has been documented since the time of Hippocrates, fewer than half of all these cases are recognized. OBJECTIVE Because p...

Mixed micelles are widely used to increase solubility and bioavailability of poorly soluble drugs. One promising antitumor drug candidate is 20(S)-protopanaxadiol (PPD), although its clinical application is limited by low water solubility and poor bioavailability after oral administration. In this study, we developed mixed micelles consisting of PPD-phospholipid complexes and Labrasol(®) and ev...
