Quantitative strain analysis of surfaces and interfaces using extremely asymmetric x-ray diffraction.

Strain can reduce carrier mobility and the reliability of electronic devices and affect the growth mode of thin films and the stability of nanometer-scale crystals. To control lattice strain, a technique for measuring the minute lattice strain at surfaces and interfaces is needed. Recently, an extremely asymmetric x-ray diffraction method has been developed for this purpose.

[Examination of the means of measuring liver function in the hepatobiliary phase].

In a field of contrast-enhanced magnetic resonance imaging of the liver, attention has been focused on evaluation of liver function using gadolinium ethoxybenzyl diethylenetriaminepentaacetic acid(EOB). In this study, we examined the possibility of obtaining liver function in only one hepatobiliary phase 60 minutes after injection. First, in regard to the difference between the signal intensity of two materials, we examined the effects of slice gap, surface coil intensity correction(SCIC), and others.

[Trial manufacture of a plunger shield for a disposable plastic syringe].

A syringe-type radiopharmaceutical being supplied by a manufacturer has a syringe shield and a plunger shield, whereas an in-hospital labeling radiopharmaceutical is administered by a disposable plastic syringe without the plunger shield. In cooperation with Nihon Medi-Physics Co. Ltd.

Spontaneous esophageal rupture treated with staged operations.

Spontaneous esophageal rupture is a life-threatening entity. Here, a 64-year-old male who presented with sudden onset of severe back pain was diagnosed as having an esophageal rupture to the right pleural cavity. Emergency operation was carried out 16 hours after the onset.

[A case of peritoneal metastasis of gastric cancer responding to TS-1, administered for four consecutive weeks with two-week rests].

We treated a patient with gastric cancer considered to be unresectable due to peritoneal metastasis, who responded remarkably to treatment with TS-1. The patient was a 62-year-old male. His diagnosis was gastric cancer, for which he underwent surgery on February 22, 2001.

[Clinical study of weekly paclitaxel administration for metastatic breast cancer based on time to progression (TTP) and survival].

We studied 13 women aged 29-62 years for response to weekly administration of paclitaxel for metastatic breast cancer. Paclitaxel was administered by 1-hour intravenous infusion at a dose of 60-80 mg/m2 once a week. Administration was continued for 3 weeks with a 1-week rest for at least 3 cycles.

[Clinical study of weekly administration of paclitaxel for advanced and metastatic gastric cancer].

Ten cases of advanced and metastatic gastric cancer treated by weekly administration of paclitaxel were studied. The patients were 50-72 years of age, including 9 men and 1 woman. In this study, paclitaxel was administered by 1 hour intravenous infusion at a dose of 50-80 mg/m2 every week.

[A case report of both CAF and docetaxel-resistant breast cancer responding to paclitaxel weekly therapy].

A 58-year-old woman underwent CAF and docetaxel therapy for lung, liver and bone metastases from breast cancer operated on 14 years ago. Because of progressive disease due to secondary resistance to CAF and docetaxel, the patient was given three courses of paclitaxel therapy (60 mg/m2, day 1, 8, 15, repeated every 4 weeks). The paclitaxel weekly therapy brought about no adverse effects and remarkable effects against lung and liver metastases (PR).

[A case of gastric cancer with multiple liver metastases responding to TS-1].

We report the case of a 58-year-old male with Stage IV gastric cancer accompanied by multiple liver metastases, which responded to chemotherapy using TS-1. The patient was treated with daily oral administration of 120 mg TS-1 for 4 weeks followed by 2 weeks rest as 1 cycle. After 4 cycles, most of the liver metastases had disappeared and serum CEA level was reduced from 140 to 53.
