Abstract
BACKGROUND The emphasis on aesthetic outcomes and quality of life after breast cancer surgery has motivated breast surgeons to develop oncoplastic breast conserving surgery (OPS). Training programs are still rare in most countries, and there is little standardization, which challenges the scientific evaluation of these techniques. This systematic review aims to assess oncological and cosmetic outcomes of OPS. METHODS After a strict selection process with precise inclusion and exclusion criteria, oncologic and aesthetic outcomes of oncoplastic surgery were searched, using the MEDLINE database up to September 30th, 2017. Available published literature was classified in levels of evidence. After a thorough screening process, only studies with the best level of evidence were included on selection. Systematic reviews and meta-analyses were not included for methodological reasons. RESULTS Titles and abstracts of 2.854 citations were identified and after screening 15 prospective studies including 1.391 patients were reviewed and scored in detail. Local relapse was found in 2.8% of cases with a wide range of follow-up (from 6 to 74 months). Close margins were retrieved in 11% of cases and positive margins in 9.4% of cases. Mastectomy was implemented in 6.9% of breast cancer patients to whom OPS was performed. Good cosmetic outcomes were detected in 90.2% of patients undergoing OPS, leaving open issues for who should perform cosmetic evaluation and which method should be used. CONCLUSION Tumor margins, mastectomy rates, and cosmetic outcomes of OPS have to be further improved by standardizing various aspects of OPS. Research efforts should focus on level I evidence assessing both oncological and aesthetic outcomes of OPS and survival rates.

Abstract
The cloning and the characterization of the heat shock 70 (hsp70) genes of the medfly C. capitata, a major agricultural pest, are presented. Six genomic clones were isolated by screening a medfly genomic library with an hsp70 genomic fragment of Drosophila melanogaster. They form two 30 kb contigs, both of which map cytogenetically in a single major heat shock puff (3L:24C) of the salivary gland polytene chromosomes. Restriction mapping and blot hybridization indicated the presence of six putative hsp70 genes in these two closely linked regions. The sequence of one of these genes suggests that it is a heat-inducible hsp70 gene. The 638-codon open reading frame shows 84% identity at the amino acid level (73.5% at the nucleotide level), relative to corresponding D. melanogaster sequences. The 5' untranslated leader sequence, approximately 200 bp long, is not interrupted by introns and is very rich (48%) in adenine residues, resembling Drosophila heat-inducible hsp70 genes. Furthermore, the promoter of this gene contains two characteristic heat shock elements close upstream from the TATA box. The levels of the hsp70 transcripts are very low at 25-30 degrees C, increase significantly at 33 degrees C and reach maximum at 39 degrees C.

Abstract
Ultrastructural analyses of polytene chromosomes from male pupal orbital bristle cells and from larval salivary glands of Ceratitis capitata were carried out. It was shown that chromatin complexes corresponding to the X chromosome heterochromatic network are surrounded by material containing ribonucleoprotein (RNP) granules 250-300 A (1 A = 0.1 nm) in diameter. RNP granules of similar size surround the spherical Y chromosome. These data point out the presence of transcriptional activity in both of these chromosomes. The absence of clear structure in chromosomal regions situated between large bands in both types of tissues was observed. These results support the hypothesis of weak synapsis between chromatids or small chromomeres of polytene chromosomes in this species. In addition, we describe a specific puff revealed in both orbital trichogen cells and salivary glands that is morphologically similar to the 93D puff of Drosophila melanogaster.
