This study evaluated whether the intensity of previously smelled odors
could unintentionally influence the subsequent judgement of odor intensity.
The predicted context effect was based on the adaptation- level theory.
Before and 25 min after either WEAK or STRONG biasing odor concentrations,
51 subjects were required to rate the intensity of 10 different odor
concentrations of California Orange Oil. After the WEAK bias, subjects
judged the odor intensity as being stronger than they did after the STRONG
bias. Thus the intensity of odors smelled 25 min earlier can
unintentionally influence subsequent odor intensity judgement. The findings
are discussed in the light of two alternative explanations, namely, a
central implicit memory process and a stimulus- level-based change at the
peripheral level.

Geldanamycin (GDM) has been modified by different type neutral/acidic/basic substituents (1–7) and by quinuclidine motif (8), transformed into ammonium salts (9–13) at C(17). These compounds have been characterised by spectroscopic and x-ray methods. Derivative 8 shows better potency than GDM in MCF-7, MDA-MB-231, A549 and HeLa (IC50s = 0.09–1.06 µM). Transformation of 8 into salts 9–13 reduces toxicity (by 11-fold) at attractive potency, e.g. MCF-7 cell line (IC50∼2 µM). Our studies show that higher water solubility contributes to lower toxicity of salts than GDM in healthy CCD39Lu and HDF cells. The use of 13 mixtures with potentiators PEI and DOX enhanced anticancer effects from IC50∼2 µM to IC50∼0.5 µM in SKBR-3, SKOV-3, and PC-3 cancer cells, relative to 13. Docking studies showed that complexes between quinuclidine-bearing 8–13 and Hsp90 are stabilised by extra hydrophobic interactions between the C(17)-arms and K58 or Y61 of Hsp90. 相似文献

The main purpose of this paper is to describe the variability of the body mass index (BMI) and selected physiological parameters (serum glucose, total serum cholesterol, systolic and diastolic blood pressure) in women before and after menopause. The empirical basis for the assessment is the material obtained in cross-sectional studies carried out in the years 1998-2001 in a group of 2204 women aged 35-65 years, residents of the Wielkopolska region, Poland. The results indicate that hormonal changes taking place in the climacterium bring about an increase in the BMI. It was observed that women receiving Hormone Replacement Therapy in the perimenopause had BMI significantly lower than naturally menopausal women. Increased levels of total serum cholesterol and blood glucose were recorded. The trend has a stronger relation with the age of the subjects than with the character of the menopause. The systolic and diastolic blood pressure values were also found to increase significantly after the menopause, but no relationship with the type of menopause was found. 相似文献
