[Auto-analysis of immunohistochemical findings for breast cancer using specified software and virtual microscopy].

Currently, the therapeutic strategy for a breast cancer patient is designed according to their histopathological, immunohistochemical and molecular findings. These findings are obtained through the collected efforts of many individual pathologists or medical technologists (MTs) and are, thus, limited by intra-observer error and potentially subjective decision making. Twenty five breast cancer specimens collected between November 2009 and February 2010 were examined for immunohistochemical expressions of estrogen receptor (ER), progesterone receptor (PgR), HER2, Ki-67, Topoisomerase II alpha (Topo IIalpha).

Missense mutation of Abcg5 in stroke-prone spontaneously hypertensive rats does not influence lymphatic sitosterol absorption regardless of the dose: comparison with Wistar rats.

The lymphatic recovery of radiolabeled sitosterol administered in various amounts to the stomach was almost the same between stroke-prone spontaneously hypertensive rats (SHRSPs), a strain having a missense mutation in ATP binding cassette transporter g5 (Abcg5), and Wistar rats, a normal strain. The results suggest that the mutation of Abcg5 in SHRSPs, compared with Wistar rats, did not influence the ability for intestinal sitosterol absorption regardless of the dose.

Missense mutation in Abcg5 in SHRSP rats does not accelerate intestinal absorption of plant sterols: comparison with Wistar rats.

Stroke-prone spontaneously hypertensive rats (SHRSP) deposit plant sterols in their bodies and have a mutation in ATP binding cassette transporter G5 (Abcg5). Lymphatic recovery rates of campesterol and sitosterol in SHRSP rats were comparable to those in Wistar rats, a strain that does not deposit plant sterols in the body and has no mutation in Abcg5. Higher absorption of stigmasterol and sitostanol was observed in SHRSP rats than in Wistar rats, but the differences between SHRSP and Wistar rats were quite small, because the absorbed amounts of these two sterols were much lower than those of campesterol and sitosterol.

Hydrolysis of micellar phosphatidylcholine accelerates cholesterol absorption in rats and Caco-2 cells.

Lymphatic recovery of cholesterol infused into the duodenum as bile salt micelles containing phosphatidylcholine (PC) was accelerated by the co-administration of phospholipase A2 in bile and pancreatic juice diverted rats. Previously we observed that cholesterol esterase, which has the ability to hydrolyze PC, caused the same effect under a similar experimental condition (Ikeda et al., Biochim.

Circular dichroism of amino acid films in UV-VUV region.

Circular dichroism (CD) spectra of sublimated films of alanine and alanine dipeptide were measured in UV-VUV region. When a film has some linear anisotropy, the apparent CD signal is known to be strongly distributed by linear anisotropy. In order to obtain the true CD spectra, we examined this disturbance for L-alanine films.
