Friction Stir Spot Welding of Aluminum and Copper: A Review.

Aluminum (Al) and copper (Cu) have been widely used in many industrial fields thanks to their good plasticity, high thermal conductivity and excellent electrical conductivity. An effective joining of dissimilar Al and Cu materials can make full use of the special characteristics of these two metals. Friction stir spot welding (FSSW), as an efficient solid-state welding method suitable for joining of dissimilar metal materials, has great prospects in future industrial applications.

Hyperfractionated accelerated radiotherapy (HART) for inoperable, nonmetastatic non-small cell lung carcinoma of the lung (NSCLC): results of a phase II study for patients ineligible for combination radiochemotherapy.

Purpose: To evaluate a hyperfractionated and accelerated radiotherapy (HART) protocol in patients with inoperable non-small cell lung carcinoma (NSCLC) who were ineligible for combination radiochemotherapy studies.

Methods And Materials: From February 1989 through August 1994, 23 patients ineligible for available combined modality protocols in our institution were enrolled and treated with HART, consisting of 63 Gy given in 42 fractions of 1.5 Gy each, twice daily, with a minimum time interval of 6 h between fractions, 5 days a week, over an elapsed time of 4.

Altered apoptotic profiles in irradiated patients with increased toxicity.

Purpose: A retrospective study of radiation-induced apoptosis in CD4 and CD8 T-lymphocytes, from 12 cancer patients who displayed enhanced toxicity to radiation therapy and 9 ataxia telangiectasia patients, was performed to test for altered response compared to healthy blood-donors and normal cancer patients.

Methods And Materials: Three milliliters of heparinized blood from each donor was sent via express post to the Paul Scherrer Institute (PSI) for subsequent examination. The blood was diluted 1:10 in RPMI medium, irradiated with 0-, 2-, or 9-Gy X-rays, and incubated for 48 h.

Rapidly alternating combination of cisplatin-based chemotherapy and hyperfractionated accelerated radiotherapy in split course for stage IIIA and stage IIIB non-small cell lung cancer: results of a phase I-II study by the GOTHA group. Group d'Oncologie Thoracique des Régions Alpines.

The prognosis of stage III non-small cell lung cancer (NSCLC) can be improved by a combination of radiotherapy (RT) and chemotherapy (CT). In this study, the GOTHA group evaluated the feasibility, tolerance, tumour response, pattern of failure and effect on survival of a combination alternating accelerated hyperfractionated (AH) RT and CT in patients with tumour stage III NSCLC. 65 patients received 3 cycles of cisplatin 60 mg/m2 and mitomycin C 8 mg/m2 on day 1, and vindesin 3 mg/m2 on days 1 and 8 in weeks 1-2, 5-6 and 9-10, alternating with AHRT, 2 daily 1.
