Loop Corrections to Supergravity on AdS_{5}×S^{5}.

We consider the four-point correlator of the stress-energy tensor multiplet in N=4 super Yang-Mills theory. In the planar limit and at large 't Hooft coupling, such a correlator is given by the corresponding holographic correlation function in IIB supergravity on AdS_{5}×S^{5}. We consider subleading corrections in the number of colors, i.

The role of intraoperative therapy by electron beam and combination of adjuvant chemotherapy and external radiotherapy in carcinoma of the pancreas.

Aims And Background: In the treatment of pancreatic carcinomas, one modality is intraoperative radiotherapy (IORT). A study was carried out to assess the feasibility of IORT alone or in a multimodality approach with postoperative adjuvant chemotherapy and external radiotherapy and to compare local control and survival of patients. Another objective of this retrospective study was to verify prognostic factors in resected patients treated with IORT.

[Description and results of a simplified procedure for intraoperative electron radiotherapy].

In San Raffaele Institute a simplified procedure for intraoperative radiotherapy (IORT) was developed. An applicator system of "guide-containers" was used to facilitate the use of IORT (with electron beam) with different treatment fields. Application of this technique was studied; no IORT related complications was observed in phase I and clinical good results are reported.

Effect of mastectomy versus mastectomy plus adjuvant ovariectomy on prolactin response to TRH in breast cancer.

The endocrine effects of ovariectomy need to be further investigated. The present study was carried out to evaluate the influence of the adjuvant ovariectomy on the mastectomy-induced changes in PRL response to TRH in breast cancer. The study included 34 patients with locally limited breast carcinoma, 18 of whom were treated with radical mastectomy, whereas the other 16 underwent mastectomy plus adjuvant ovariectomy.
