Abstract
15012 Background: CP every 3 weeks is the standard for pts with OC, but elderly pts frequently receive modified schedules or single agent chemotherapy to avoid toxicity. A prospective phase 2 study was conducted to describe tolerability and activity of a weekly schedule of CP in elderly pts with OC. Methods: Pts aged ≥70 years with chemo-naive OC, stage IC-IV, ECOG PS≤2 were eligible. Treatment was C (AUC 2) + P (60 mg/m2) on days 1, 8, 15 every 4 weeks, up to 6 cycles. A 2-stage minimax design was applied. With rate of pts without unacceptable toxicity in the first 3 cycles (UT) as primary endpoint, alpha 0.05 and beta 0.10, p0=0.75, p1=0.95, ≥23/26 pts without UT were required at the final stage. Toxicity was coded with NCI-CTC and response by RECIST. Geriatric assessment was performed by ADL (Activities of Daily Living) and IADL (Instrumental ADL). Results: 26 pts were enrolled. Median age was 77 (range 70–84). PS0: 10 pts, PS1: 16 pts. 14 pts (53.8%) had ≥2 comorbidities. 32%/72% had some ADL/ IADL dependency, respectively. 23 pts (88.5%) did not suffer UT. The 3 UT recorded were g3 heart rhythm (1 pt), g3 liver (1 pt), prolonged haematological toxicity (1 pt). Other main toxicities: g3 thrombocytopenia 1 pt, g2 constipation 2 pts (8%), g1 neuropathy 4 pts (15%). Out of 13 pts with at least one measurable lesion, 4 partial responses were observed (response rate 30.8%, 95% exact CI: 9.1–61.4). Out of 6 pts with non-measurable disease and 2 pts evaluable only for Ca125, 4 complete responses were observed (50%). Conclusions: In this series of elderly OC pts, characterized by a high incidence of comorbidities and functional impairment, weekly CP has a favourable toxicity profile. In this setting, a comparison of weekly vs 3-weekly CP is advisable to compare efficacy. No significant financial relationships to disclose.

Abstract
The aim of this research was to optimize protocols for freezing spermatozoa of seabream (Sparus aurata). All the phases of the cryopreservation procedure (sampling, choosing the cryoprotective extender, cooling, freezing, and thawing) were studied in relation to the species of spermatozoa under examination, so as to be able to restore on thawing the morphological and physiological characteristics of fresh semen. Seabream spermatozoa were collected by stripping and transported to the laboratory chilled (0-2 degrees C). Five cryoprotectants, dimethyl sulfoxide (Me(2)SO), ethylene glycol (EG), 1,2-propylene glycol (PG), glycerol, and methanol, were tested at concentrations between 5 and 15% by volume to evaluate their effect on the motility of semen exposed for up to 30 min at 26 degrees C. The less toxic cryoprotectants, 10% EG, 10% PG, and 5% Me(2)SO, respectively, were added to 1% NaCl to formulate the extenders for freezing. The semen was diluted 1:6 with the extender, inserted into 0.25-ml plastic straws by Pasteur pipette, and frozen using a cooling rate of either 10 or 15 degrees C/min to -150 degrees C followed by transfer and storage in liquid nitrogen (-196 degrees C). The straws were thawed at 15 degrees C/s. On thawing, the best motility was obtained with 5% Me(2)SO, although both 10% PG and EG showed good results; no differences were found between the two freezing gradients, although semen frozen with the 10 degrees C/min gradient showed a slightly higher and more prolonged motility.

Abstract
Extracellular ATP can often induce tumor cell cytotoxicity; however, the molecular mechanisms of these effects are mostly unknown. We investigated whether modifications in transmembrane ion fluxes are involved in the determination of ATP-cytotoxicity. We have found that cultured human tumor cells derived from colon (LoVo) and lung (A549) carcinomas are resistant to ATP, while LoVo-Dx cells (a doxorubicin-resistant derivative of LoVo cells) and melanoma GLL-19 cells are highly sensitive to this nucleotide. 48 h exposure to 100 nM verapamil increases sensitivity of LoVo and A549 cells to ATP. This effect is completely reverted by the addition of the calcium ionophore A23187. Conversely, 4 h exposure to 100 nM ouabain, which blocks the Na+/K+ exchange pump, neutralyzes ATP cytotoxicity against LoVo-Dx and GLL-19 cells. Furthermore, ATP-mediated cytotoxic effects on these cells are completely antagonized by ADP-beta-S, a non hydrolyzable analogue of ATP. These findings suggest that transmembrane ion flux modifications play a critical role in ATP cytotoxicity and that ATP binding on surface receptors and probably nucleotide hydrolysis are needed for inducing cytotoxicity on human tumor cells.
