Positional relationship between ball and fingers for accurate baseball pitching.

Accurately throwing an object to a target position repeatedly is one of the specific human motor skills. The final arrival position of a thrown ball can be determined by its physical state at release. In baseball pitching, reducing the variability of the velocity angle of the ball at release (release angle) is important for reducing the variability of the pitch location.

Endometrial scraping cytology in women with extragenital malignancies.

Objective: To clarify the usefulness of endometrial scraping smears in women with extragenital malignancies.

Study Design: A total of 4,335 endometrial scraping smears were obtained during the 5-year period 1995-1999 at the National Kyushu Cancer Center and were retrospectively analyzed regarding extragenital malignancies.

Results: There were 88 cases of extragenital malignancies.

11q23-24 loss is associated with chromosomal instability in endometrial cancer.

A loss of the DNA copy number at chromosomal region 11q23-24 as detected by comparative genomic hybridization (CGH) is a marker of poor prognosis in patients with endometrial cancer. Malignant tumors display genetic instability, which is classified into two types: microsatellite instability (MIN) and chromosomal instability (CIN). In the present study, we examined whether there is a relation between loss of 11q23-24 and genetic instability in endometrial adenocarcinoma.
