Abstract
Breast implants are extensively employed for both reconstructive and esthetic purposes. However, the safety of breast implants with textured surfaces has been questioned, owing to a potential correlation with anaplastic large-cell lymphoma and the recurrence of breast cancer. This study investigates the immune response elicited by different prosthetic surfaces, focusing on the comparison between macrotextured and microtextured breast implants. Through the analysis of intraoperatively harvested periprosthetic fluids and cell culture experiments on surface replicas, we demonstrate that macrotextured surfaces elicit a more pronounced chronic-like activation of leucocytes and an increased release of inflammatory cytokines, in contrast to microtextured surfaces. In addition, in vitro fluorescent imaging of leucocytes revealed an accumulation of lymphocytes within the cavities of the macrotextured surfaces, indicating that the physical entrapment of these cells may contribute to their activation. These findings suggest that the topography of implant surfaces plays a significant role in promoting a chronic-like inflammatory environment, which could be a contributing factor in the development of lymphomas associated with a wide range of implantable devices.

Abstract
BACKGROUND Surgical site infection represents the most severe complication in prosthetic breast reconstruction. Risk profiling represents a useful tool for both clinicians and patients. MATERIALS AND METHODS In our hospital, 534 breast reconstructions with tissue expander implants, in 500 patients, were performed. Several clinical variables were collected. In our study, we evaluated the different inflammatory markers present in the periprosthetic fluid and we compared them with the ones present in plasma. RESULTS The surgical site infection rate resulted to be 10.5%, and reconstruction failed in 4.5% of the cases. The hazard ratio for complications was 2.3 in women over 60 (CI: 1.3-4.07; p = 0.004), 2.57 in patients with expander volume ≥ 500 cc (CI: 1.51-4.38; p < 0.001), 2.14 in patients submitted to previous radiotherapy (CI: 1.05-4.36; p < 0.037), and 1.05 in prolonged drain use (CI: 1.03-1.07; p < 0.001). 25-OH, PCT, and total protein were less concentrated, and ferritin and LDH were more concentrated in the periprosthetic fluid than in plasma (p < 0.001). CRP (p = 0.190) and β-2 microglobulin (p = 0.344) did not change in the two fluids analyzed. PCT initial value is higher in patients who underwent radiotherapy, and it could be related to the higher rate of their postoperative complications. Patients with a tissue expander with a volume ≥ 500 cc show an increasing trend for CRP in time (p = 0.009). CONCLUSIONS Several risk factors (prolonged time of drains, age older than 60 years, and radiotherapy) have been confirmed by our study. The study of markers in the periprosthetic fluid with respect to their study in plasma could point toward earlier infection detection and support early management.

Abstract
Controlling oxidative stress through the activation of antioxidant pathways is crucial in bone homeostasis, and impairments of the cellular defense systems involved contribute to the pathogenesis of common skeletal diseases. In this work we focused on the dipeptidyl peptidase 3 (DPP3), a poorly investigated ubiquitous zinc-dependent exopeptidase activating the Keap1-Nrf2 antioxidant pathway. We showed Dpp3 expression in bone and, to understand its role in this compartment, we generated a Dpp3 knockout (KO) mouse model and specifically investigated the skeletal phenotype. Adult Dpp3 KO mice showed a mild growth defect, a significant increase in bone marrow cellularity, and bone loss mainly caused by increased osteoclast activity. Overall, in the mouse model, lack of DPP3 resulted in sustained oxidative stress and in alterations of bone microenvironment favoring the osteoclast compared to the osteoblast lineage. Accordingly, in vitro studies revealed that Dpp3 KO osteoclasts had an inherent increased resorptive activity and ROS production, which on the other hand made them prone to apoptosis. Moreover, absence of DPP3 augmented bone loss after estrogen withdrawal in female mice, further supporting its relevance in the framework of bone pathophysiology. Overall, we show a nonredundant role for DPP3 in the maintenance of bone homeostasis and propose that DPP3 might represent a possible new osteoimmunological player and a marker of human bone loss pathology. © 2019 American Society for Bone and Mineral Research.

Abstract
The need for treating subclinical hypothyroidism (SCH) in women undergoing assisted reproduction technology (ART) is under debate. Moreover, it is known that controlled ovarian hyperstimulation (COH) protocols may impair the thyroidal axis. Therefore, we evaluated if levothyroxine (L-T4) supplementation in SCH women before undergoing ART positively affects the main reproductive outcomes. We retrospectively analyzed in vitro fertilization (IVF) data of 4147 women submitted to 6545 cycles in a tertiary care IVF Center (January 2009-December 2014). L-T4 (1.4-2.0 mcg/kg) treatment was offered to all women with a pre-cycle TSH >2.5 mIU/L before starting COH and main ART outcomes were compared in euthyroid and L-T4-treated women undergoing ART. Among 4147 women, 1074 (26%) were affected by SCH and were treated with L-T4 before COH was started. No statistically significant differences among L-T4-treated and euthyroid women group were observed regarding pregnancy rate, respectively, per cycle (27.67% vs 26.37%; p = .314) and per embryo transfer (30.13% vs 29.17%; p = .489), live birth rate, respectively, per cycle (21.58% vs 20.38%; p = .304) and per embryo transfer (23.49 vs 22.54%; p = .449) and the rest of primary and secondary efficacy endpoints. Early L-T4 treatment for infertile women with a subtle thyroid dysfunction may mitigate and protect from the negative effects of SCH in the setting of ART, and may preventively overcome also the negative impact of COH on thyroidal axis.

Abstract
AIM We described two case reports of AIH/SSc overlap syndrome and reviewed literatures regarding this issue. BACKGROUND AIH is a chronic hepatitis of unknown aetiology characterized by continuing hepatocellular necrosis and inflammation. AIH overlap syndromes have been reported with other autoimmune diseases. PATIENTS AND METHODS According to the classification criteria for SSc, we conducted a retrospective chart review of 35 cases with biopsy-proven AIH over the past 5 years at our institution. We reviewed the MEDLINE database using the appropriate key-words. RESULTS A chart review of 35 cases (M/F ratio 1:2, mean age 47.6±10.3 years) revealed nine patients (9/35, 25.7%) with CTD (four males and three females with a mean age of 45.1±8.4 years). All patients had ANA. Four patients were SSA/Ro positive UCTD (1/35, 2.85%), and six patients developed SLE (6/35, 17.1%). Only two female patients (2/35, 5.7%) with specific SSc AAb developed a systemic sclerosis. We described a patient with AIH who was diagnosed with diffuse systemic sclerosis-sine scleroderma with positive anti-centromere B and SSA/Ro52 KDa antibodies. We also reported a patient with AIH who was diagnosed limited SSc with contemporary presence of anti-centromere A and anti-RNA polymerase III antibody. CONCLUSION We suggest that SSc may be considered to be one of the manifestations associated with AIH. Patients with AIH may have an increased risk to develop SSc and should be followed, especially when Raynaud phenomenon was found.

Abstract
Autosomal recessive osteopetrosis (ARO) is a rare genetic bone disease with genotypic and phenotypic heterogeneity, sometimes translating into delayed diagnosis and treatment. In particular, cases of intermediate severity often constitute a diagnostic challenge and represent good candidates for exome sequencing. Here, we describe the tortuous path to identification of the molecular defect in two siblings, in which osteopetrosis diagnosed in early childhood followed a milder course, allowing them to reach the adult age in relatively good conditions with no specific therapy. No clearly pathogenic mutation was identified either with standard amplification and resequencing protocols or with exome sequencing analysis. While evaluating the possible impact of a 3'UTR variant on the TCIRG1 expression, we found a novel single nucleotide change buried in the middle of intron 15 of the TCIRG1 gene, about 150 nucleotides away from the closest canonical splice site. By sequencing a number of independent cDNA clones covering exons 14 to 17, we demonstrated that this mutation reduced splicing efficiency but did not completely abrogate the production of the normal transcript. Prompted by this finding, we sequenced the same genomic region in 33 patients from our unresolved ARO cohort and found three additional novel single nucleotide changes in a similar location and with a predicted disruptive effect on splicing, further confirmed in one of them at the transcript level. Overall, we identified an intronic region in TCIRG1 that seems to be particularly prone to splicing mutations, allowing the production of a small amount of protein sufficient to reduce the severity of the phenotype usually associated with TCIRG1 defects. On this basis, we would recommend including TCIRG1 not only in the molecular work-up of severe infantile osteopetrosis but also in intermediate cases and carefully evaluating the possible effects of intronic changes.

Abstract
There is a well-established link between inflammation and cancer of various organs, but little data are available on inflammation-associated markers of diagnostic and prognostic clinical utility in pulmonary malignancy. Blood samples were prospectively collected from 75 resectable lung cancer patients before surgery and in a cohort of 1,358 high-risk subjects. Serum levels of long pentraxin 3 (PTX3) were determined by high-sensitivity ELISA. PTX3 immunostaining was evaluated by immunohistochemistry in cancer tissue. Serum PTX3 levels in the high-risk population were not predictive of developing subsequent lung cancer or any other malignancy; however, serum PTX3 values in patients with lung cancer were significantly higher compared with cancer-free heavy smokers. With a cutoff of 4.5 ng/ml, specificity was 0.80, sensitivity 0.69, positive predictive value 0.15 and negative predictive value 0.98. The receiver operating curve (ROC) for serum PTX3 had an area under the curve (AUC) of 83.52%. Preoperative serum PTX3 levels in lung cancer patients did not correlate with patient outcome, but high interstitial expression of PTX3 in resected tumor specimens was a significant independent prognostic factor associated with shorter survival (p < 0.001). These results support the potential of serum PTX3 as a lung cancer biomarker in high-risk subjects. Furthermore, PTX3 immunohistochemistry findings support the role of local inflammatory mechanisms in determining clinical outcome and suggest that local expression of PTX3 may be of prognostic utility in lung cancer patients.

Abstract
Drug-induced crystalluria is a cause of acute renal failure that has not to be overlooked. Especially sulfonamides are known to be little solubles in acidic urine. Among these drugs, sulfadiazine produces the so-called shocks of wheat crystals, whose formation can be avoided by opportune hydration and alkalinization of the patient. Sulfamethoxazole is another drug of this class that has seldom been reported to cause a pleomorphic crystalluria. We report the case of two patients treated with sulfamethoxazole who developed a crystalluria that is very similar to the sulfadiazine one. Sulfamethoxazole is widely used in clinical practice in association with trimethoprim and it is known to cause acute renal failure, although little is known about the pathogenesis of this nephrotoxicity. Our cases, along with the cases previously reported, may suggest that sulphamethoxazole can act as a nephrotoxic agent through crystals production. Notably, in our cases, discontinuation of the drug led to disappearance of the crystals.

Abstract
Celiac disease (CD) is now considered, more than a just gluten sensitivity enteropathy, a multiple and systemic immune-mediate disorder triggered by the ingestion of wheat gluten and related proteins. Following the discovery of a link between gluten and CD, it was demonstrated that gliadin, one of the two principal protein groups comprising gluten, plays a key role in CD. It has since become clear that the different and crucial roles of gliadin in CD result from its ability to activate multiple signaling pathways that modulate CD pathology. Most of these pathways involve the host innate and adaptive immune responses, but some pathways are activated when gliadin interacts with the intestinal cellular compartment. The long pentraxin (PTX3), a marker of the acute-phase inflammatory response, plays an important role in innate immunity and in modulation of the adaptive immune response. We investigated whether CD patients, considered as a model of gluten-sensitivity condition, have increased PTX3 levels. Our data showed that PTX3 serum levels were high in active CD patients and serum levels of PTX3 correlated with DGP IgA levels. We provide evidences that the bad compliance of GFD in patients 2 concurred with a pathological PTX3 concentration that could follow the improvement of both gastrointestinal and extraintestinal symptoms. We hypothesized that PTX3 is able to modulate the innate response to gliadin in CD and it could regulate the adaptive immune response. It is also evidenced that a common "wooden horse" of CD and Non Celiac Gluten Sensitivity (NCGS) is the ingestion of gluten and related toxic peptides. At the moment we don't have adequate elements to suggest the use of PTX3 in diagnosis of NCGS, but we are obliged to speculate about the possible role of PTX3 molecules in NCGS pathogenesis. The identified new strategies and uses of PTX3 could improve the management of gluten sensitivity conditions in the next future.

Abstract
The present study is the first to evaluate the expression and activity of MnSOD, Cu/ZnSOD and catalase in human gastric samples, since ROS play a significant role in the pathogenesis of different forms of malignancy inducing mutations and various diseases such as gastric cancer. Biopsies and surgical samples from 53 patients (male/female 22/31, mean age 56.5+/-15.8 years) consisted of 15 healthy, 12 autoimmune atrophic gastritis, 10 Helicobacter pylori (HP) infection, 8 HP-negative chronic gastritis (CG) and 8 adenocarcinoma cases. Enzyme activity and expression were evaluated by spectrophotometry and immunoblotting after specific extraction in phosphate buffer. We found that MnSOD activity was increased in adenocarcinoma, CG and HP tissues (p<0.05-0.001), while Cu/ZnSOD was significantly lower in adenocarcinoma and HP tissues (p<0.001) when compared to the healthy control. MnSOD and Cu/ZnSOD were expressed to a significantly higher degree in adenocarcinoma and HP tissues (p<0.05 and <0.001 respectively) and to a significantly lower degree in CG tissues with respect to the healthy patients (p<0.05 and <0.001). A significant decrease in CAT activity in adenocarcinoma and HP tissues was observed (p<0.01 and <0.05). Gastric human neoplasms showed significant changes in antioxidant enzymes, that represent the first line in antioxidant protection against radical attack. The difficulties in correlating the antioxidant enzyme with the neoplasms was related to the complexity of the biochemical pathways that regulate the cellular redox balance. Our results are important in enhancing the understanding of the role that these enzymes play in the promotion/suppression of the carcinogenesis cascade in human gastric mucosa.

Abstract
CYP1A sub-family represents the main form of cytochrome P450 involved in benzo[a]pyrene (B[a]P) detoxification, but there are no clear evidences about its presence in invertebrates. 7-Ethoxy resorufin O-deethylase (EROD) activity is strictly related to CYP1A presence, at the same time P450-dependent oxidative metabolism leads to reactive oxygen species (ROS) production, thought to be an important mechanism of pollutant-mediated toxicity in aquatic organisms. Superoxide dismutases (SODs), EROD and CYP1A activities and/or expressions were detected in haemocytes of pooled clams (Chamelea gallina) and cell-free haemolymph after 24 h, 7 and 12 days of exposure to 0.5 mg/L of B[a]P. After 24 h, B[a]P content was maximum in whole tissues. A 61 kDa band was recognized in haemocytes and cell-free haemolymph by polyclonal anti-fish CYP1A, while 53.5 and 63.8 kDa CYP1A immunopositive proteins were discriminate without differences of expression. Differently, EROD, MnSOD activity/expression and ECSOD expression decreased in haemocytes and haemolymph. C. gallina immune system presents an interesting response dose/time exposure of B[a]P and the 7 days condition highlights the major effects of xenobiotic action. The identification of basal EROD levels supports the possible presence of the CYP1A, never identified in C. gallina and more specifically never isolated in immune cells, as confirmed by CYP1A-immunopositive proteins identification.

Abstract
Effects of benzo(a)pyrene [B(a)P] (at a nominal concentration of 0.5 mg/L) on immune responses of the clam Chamelea gallina were investigated after 1, 7, and 12 days exposure. Total hemocyte count (THC), hemocyte volume, phagocytic activity, lysozyme-like activity in both hemocyte lysate (HL) and cell-free hemolymph (CFH) were measured. As unexpected alterations in hemocyte adhesion capability were observed in short-term hemocyte cultures for phagocytosis assays after a 1-day exposure, an adhesion test (not included in the original experimental setup) was performed after 7 and 12 days of exposure only. The survival-in-air test was carried out to evaluate general stress conditions in B(a)P-exposed clams. No alterations in THC was observed, whereas exposure for 7 and 12 days to B(a)P significantly decreased phagocytic activity and adhesion capability when compared with controls. Significant decreases in lysozyme activity were observed in CFH and HL, with respect to controls. B(a)P was also shown to alter the resistance to air exposure of clams. The LT(50) values fell from 9 days in control clams to 7 days in 1-day-exposed animals, and from 6 days in control clams to 5 days in 7-day-exposed bivalves. No significant variations in LT(50) values were recorded after 12 days of exposure. Results highlight a relationship between B(a)P exposure and alterations in hemocyte functionality and suggest that the contaminant induced irreversible immunosuppression in C. gallina, by altering phagocytic activity, adhesion capability, and enzymatic activity. Conversely, reduction in resistance to air exposure was reversible, suggesting that impairment of important physiological functions of clams occurred in the first phases of exposure only.

Abstract
Rac GTPases are members of the Rho family regulating the actin cytoskeleton and implicated in neuronal development. Ubiquitous Rac1 and neuron-specific Rac3 GTPases are coexpressed in the developing mammalian brain. We used Cre-mediated conditional deletion of Rac1 in neurons combined with knockout of neuron-specific Rac3 to study the role of these GTPases in neural development. We found that lack of both genes causes motor behavioral defects, epilepsy, and premature death of mice. Deletion of either GTPase does not produce evident phenotypes. Double-knockout mice show specific defects in the development of the hippocampus. Selective impairment of the dorsal hilus of double-knockout animals is associated with alteration in the formation of the hippocampal circuitry. Axonal pathways to and from the dorsal hilus are affected because of the deficit of hilar mossy cells. Moreover, analysis of Rac function in hippocampal cultures shows that spine formation is strongly hampered only in neurons lacking both Rac proteins. These findings show for the first time that both Rac1 and Rac3 are important for the development of the nervous system, wherein they play complementary roles during late stages of neuronal and brain development.

Abstract
Chloramphenicol (CA) is a largely used antibiotic and it is an inhibitor of protein synthesis that also induces ROS production. In this work there were investigated activities and expressions in the Adriatic bivalve Chamelea gallina of some antioxidant and detoxification proteins like superoxide dismutase (Mn-SOD, Cu/Zn-SOD), catalase (CAT) and Cytochrome P450 (CYP1A). Clams exposed to 5mgl(-1) of chloramphenicol were sampled 2, 4 and 8 days after treatment (CA2, CA4 and CA8). SODs, CAT, and CYP1A activity and/or expression were detected in pooled digestive glands by Western blotting and by spectrophotometrical analysis. Enzymes activities increase during the entire antibiotic exposure. With respect to the control Cu/Zn-SOD expression increases, while Mn-SOD expression decreases significantly after 4 days. Two CYP1A immunopositive-proteins (57.7 and 59.8kDa) were detected. The lower band significantly decreases in CA8, the upper one also in CA4 condition. High levels of Mn-SOD, CAT activity and Cu/Zn-SOD expression, indicate intense ROS production while Mn-SOD expression inhibition might be ascribable to mitochondrial alterations due to CA and indirectly to ROS. CYP1A1 action determines H2O2 production that would contribute to a CYP1A1 gene promoter down regulation, a response to oxidative stress with the antioxidant enzymes activation as a final result. This study highlights the close association, in C. gallina, in presence of chloramphenicol, between SOD/CAT and CYP system, and it appear particularly interesting to the lack of similar researches on mollusc species.

Background Tumor cell contamination of the apheresis in multiple myeloma is likely to affect disease-free and overall survival after autografting. Objective To purge myeloma aphereses from tumor contaminants with a novel culture-based purging method. Methods We cultured myeloma-positive CD34+ PB samples in conditions that retained multipotency of hematopoietic stem cells, but were unfavourable to survival of plasma cells. Moreover, we exploited the resistance of myeloma plasma cells to retroviral transduction by targeting the hematopoietic CD34+ cell population with a retroviral vector carrying a selectable marker (the truncated form of the human receptor for nerve growth factor, ΔNGFR). We performed therefore a further myeloma purging step by selecting the transduced cells at the end of the culture. Results Overall recovery of CD34+ cells after culture was 128.5%; ΔNGFR transduction rate was 28.8% for CD34+ cells and 0% for CD138-selected primary myeloma cells, respectively. Recovery of CD34+ cells after ΔNGFR selection was 22.3%. By patient-specific Ig-gene rearrangements, we assessed a decrease of 0.7–1.4 logs in tumor load after the CD34+ cell selection, and up to 2.3 logs after culture and ΔNGFR selection. Conclusion We conclude that ex-vivo culture and retroviral-mediated transduction of myeloma leukaphereses provide an efficient tumor cell purging.

Abstract
Evaluation of: Hsu PI, Chen CH, Hsieh CS et al.: α1-antitrypsin precursor in gastric juice is a novel biomarker for gastric cancer and ulcer. Clin. Cancer Res. 13(3), 876–883 (2007) [1] . The authors have identified the α1-antitrypsin precursor as a new protein marker of gastric cancer in gastric juice by 2D electrophoresis gel and mass spectrometric analyses. Three different pathologic classes of patients were considered with duodenal ulcer, gastric ulcer and gastric cancer and compared with healthy cases. α1-antitrypsin precursor was present, like the main peptide, in the specific band pattern, and seemed to be more expressed not only in advanced gastric cancer, but also in early forms of tumor. The study provides a fine contribution to this field of medicine, significantly correlating the α1-antrypsin precursor with gastric hypoacidity, gastric ulcer and gastric cancer. In addition, the utilization of gastric juice for biomarker recognition avoids the invasive resection of tissues. In conclusion, the research underlines, with an innovative and thorough approach, the role of the α1-antitrypsin precursor as a valid biomarker in gastric cancer and ulcers. However, it does not contribute to the advancement of research aimed at discovering the possible origin of the protein, and this could be the aim of future investigations.

Abstract
The effects of water-borne exposure to benzo[a]pyrene (36 h; celite-bound 0.44 mg L(-1) B[a]P) on cytochrome P450 (CYP) and superoxide dismutases (SODs) were examined in digestive gland of the blood clam, Scapharca inaequivalvis. B[a]P accumulation and elimination were rapid, with maximum whole-body concentrations of 1.78 ng g(-1) wet wt after 12 h of treatment, followed by a progressive decline to 0.89 ng g(-1) at 36 h. The presence of B[a]P resulted in an increase in total CYP of digestive gland microsomes from 54+/-14 to 108+/-21 pmol/mg protein (mean+/-SD; p<0.05, 24 h). Increases were also seen in microsomal CYP1A1/1A2-immunopositive protein (50.5 kDa app. mol. wt; p<0.05), but not CYP2E1-immunopositive protein (49 kDa app. mol. wt.), indicating a specific response of the former isoform. Exposure to B[a]P produced a steady increase in Mn-SOD digestive gland activity (p<0.01; p<0.05) but no significant change in Cu/Zn-SOD activity. The respective proteins, measured by western blotting, were not significant induced after B[a]P exposure. Cu/Zn-SOD and Mn-SOD activities were correlated with total CYP levels (r=0.96 and 0.63, respectively), indicating a role for CYP in reactive oxygen species (ROS) production during exposure. Both 'NADPH-independent' and NADPH-dependent metabolism of B[a]P by digestive gland microsomes was seen, producing mainly 1,6-, 3,6- and 6,12-diones, with some phenols and 7,8-dihydrodiol; putative protein adducts were also formed. Redox cycling of the diones may also have contributed to ROS production, leading to the increased SOD activities.

Abstract
The effects of high temperatures on the clam, Chamelea gallina, generally recognised as a low tolerant bivalve species, were studied by evaluating some functional responses of the haemocytes. The animals were kept for 7days at 20, 25 and 30 degrees C and total haemocyte count (THC), phagocytosis, lysozyme activity (in both haemocyte lysate and cell-free haemolymph), activity and expression of the antioxidant enzyme superoxide dismutase (SOD) (in both haemocyte lysate and cell-free haemolymph) were chosen as biomarkers of exposure to high temperatures. The survival-in-air test was also performed. During the experiment, the clams showed differing burrowing behaviour: the animals kept at 20 and 25 degrees C burrowed completely, whereas at 30 degrees C the clams progressively emerged from the sediment and then remained on the surface. The highest temperature significantly increased THC, whereas it decreased the phagocytic activity of haemocytes. The haemocyte size frequency distribution in clams kept at 30 degrees C showed that the cell population of about 8-10microm was markedly reduced compared to clams kept at 20 and 25 degrees C. In clams maintained at 25 degrees C, lysozyme activity was significantly increased in haemocyte lysate, whereas it was markedly decreased in cell-free haemolymph. Total SOD activity significantly decreased in haemocytes from clams held at 30 degrees C whereas it increased in cell-free haemolymph from clams held at 25 degrees C and 30 degrees C. A significant decrease in haemocyte Mn-SOD and Cu/Zn-SOD activities was found with increasing temperature. In cell-free haemolymph, the highest Mn-SOD activity was recorded at 30 degrees C, whereas the Cu/Zn-SOD activity showed no significant changes in clams maintained at different temperatures. SOD isoform expression exhibited different patterns in haemocyte lysate and cell-free haemolymph. The resistance to air exposure of clams kept at 30 degrees C was shown to decrease significantly, LT(50) values fell from 6days in clams kept at 20 degrees C and 25 degrees C to 4days in those kept at 30 degrees C.

Abstract
Gastric cancer is the second most common cancer worldwide. The involvement of reactive oxygen species (ROS) in the pathogenesis of gastric malignancies is well known. Many human tumours have shown significant changes in the activity and expression of superoxide dismutase (SOD), which might be correlated with clinical-pathological parameters for the prognosis of human carcinoma. The aim of this study is the detection of MnSOD and CuZnSOD activity and their expression in gastric adenocarcinoma and healthy tissues. Gastric samples (adenocarcinoma and healthy tissues) harvested during endoscopy or resected during surgery were used to determine MnSOD and CuZnSOD activity and expression by spectrophotometric and Western blotting assays. The total SOD activity was significantly higher (p<0.05) in healthy mucosa with respect to gastric adenocarcinomas. No differences were found in MnSOD activity and, on the contrary, CuZnSOD activity was significantly lower (p<0.001) in cancer samples with respect to normal mucosa. The rate of MnSOD/CuZnSOD activity in adenocarcinoma was over ninefold higher than that registered in healthy tissues (p<0.05). Moreover, in adenocarcinoma MnSOD activity represented the 83% of total SOD with respect to healthy tissues where the ratio was 52% (p<0.001). On the contrary, in cancer tissues, CuZnSOD activity accounted for only 17% of the total SOD (p<0.001 if compared with the values recorded in normal mucosa). After immunoblotting, MnSOD was more expressed in adenocarcinoma with respect to normal mucosa (p<0.001), while CuZnSOD was similarly expressed in adenocarcinoma and healthy tissues. The SOD activity assay might provide a specific and sensitive method of analysis that allows the differentiation of healthy tissue from tumour tissue. The MnSOD to CuZnSOD activity ratio, and the ratio between these two isoforms and total SOD, presented in this preliminary study might be considered in the identification of cancerous from healthy control tissue.

Abstract
The relationship between a supposed effect of molluscan extracts on bioluminescent bacteria and metal concentrations in the extracts was investigated. For this purpose a biotoxicological assay based on bioluminescent bacteria (BLB) and extracts from metal exposed molluscs, Scapharca inaequivalvis, was optimized to monitor Cd and Cu marine pollution. Cu and Cd concentrations increased in tissues of experimentally exposed molluscs. Molluscan extracts inhibited the bacterial luminescence, the inhibition decreasing as the time of mollusc exposure to metals increased, suggesting a reduction of the "bioactive" metals. In regard to the use of BLB test in environmental monitoring, the analysis of Cu, Cd, and metallothionein (MT) was first performed in tissues from molluscs collected in three different areas of Northern Adriatic Sea. Metal concentrations reached maximum values in the gills, while Cd was mostly bound to MT in the kidney. Significant differences in metals and MT concentrations were found depending on the sampling sites. The biotoxicological assay resulted slightly correlated with the biochemical parameters.

Abstract
We have measured the concentrations of heavy metals in soils, earthworms and tissues of woodcocks in Quaderna Valley, northern Italy. The soil concentration of metals analysed in this research is consistent with data reported by other authors for uncontaminated or slightly contaminated soils. In earthworms, metals were mostly accumulated in the encapsulating chloragogenous tissue; the positive correlation between Cu concentration in the soil and in earthworms is noteworthy. Heavy metal distribution in the tissues of woodcock showed that Cd accumulation in the kidney was linked to the diet. Cu and Fe were preferentially concentrated in the liver and Zn in the testis. Kidney Cd and Zn concentrations were higher in adults than in juveniles. In addition, a main kidney metallothionein isoform, containing Cd and Zn, was isolated. In the kidney, Cd levels were linearly correlated with the concentration of metallothionein. Of the investigated metals, Cd raises the greatest concern, due to the increasing soil contamination by human activities.

Abstract
We assessed mammaglobin (MMG) gene expression in bone marrow (BM) aspirates from patients with advanced breast cancer who had received a reduced-intensity conditioning and stem cell allografting, in order to detect a graft-versus-tumor effect on micrometastatic disease. Nine patients received a reduced-intensity conditioning with fludarabine, cyclophosphamide, and thiotepa, followed by peripheral blood allografting from HLA-identical sibling donors. Nested RT-PCR analysis with sequence-specific primers for MMG was carried out on a monthly basis on BM samples. Three patients had MMG-positive BM, four patients had MMG-negative BM before allografting, and two were undetermined. In two patients, a clinical response after allografting (partial remission) occurred concurrently with the clearance of MMG expression, at a median of 6 months after allografting, following immune manipulation. In two patients, a prolonged stable disease and negative MMG expression occurred after day +360 from allografting. In two patients, progression of the disease was associated with MMG RT-PCR changing from negative to positive. In one case, a disease response occurring after donor lymphocyte infusion and grade II acute GVHD was heralded by negativization of MMG expression. Although preliminary, these data suggest that a graft-versus-breast cancer effect is detectable on micrometastatic BM disease.

Abstract
Leptin, a protein produced and secreted by adipocytes, is know to regulate food intake and whole-body energy metabolism, but knowledge about its possible effect in bovine mammary gland is scarce. Leptin may be involved in the regulation of glucose transport even though this effect at the tissue level remains controversial. Once uptaken by the mammary gland, glucose is utilised in several ways but the majority, about 60-70%, is drained for lactose synthesis. This study was aimed at investigating the effect of leptin on glucose regulation in bovine mammary gland. We have examined the effects of leptin on the expression of GLUT1 mRNA, pyruvate kinase (PK) as well as glucose-6-phosphate dehydrogenase (G6PDH) activity. Treatment of mammary gland explants with recombinant leptin did not influence glucose assimilation, pathway transport (GLUT1 mRNA) and glucose metabolism (PK and G6PDH) in this tissue. The results from this study seem to exclude an involvement of leptin in glucose uptake and metabolism in bovine mammary gland.

Abstract
Metal concentrations in different tissues of Sparus aurata are linked to the functional role of the investigated organ: in the liver, Zn and Cu are highly concentrated, due to the detoxification and storage processes typical of the hepatic tissue. Comparison between control specimens of farmed and wild gilthead seabream resulted in significant differences in Zn and Cu concentrations between the tissue metal levels of the two populations. The cadmium levels, always less than 1 microg/g wet weight, were indicative of a low exposure to the non essential element. In Cu-exposed fish the metal was mostly accumulated in the liver and to a lesser extent in the gills in a dose-dependent manner, whereas zinc concentrations were unaffected by the metal treatment. In the liver a 1.6-fold and 4-fold increase was observed in fish exposed to 0.1 microg/mL and 0.5 microg/mL respectively; moreover, Cu exposure caused an increase of MTmRNA and CuMT. On this basis, the two molecular parameters could be considered as useful biomarkers of an early cellular response against Cu toxicity.

Abstract
The anoxic survival time of the bivalves Chamelea gallina, Cerastoderma edule and Scapharca inaequivalvis from two different ecosystems and differing anoxia tolerances was studied in static (closed) and flow-through systems. The antibiotics chloramphenicol, penicillin and polymyxin were added, and molybdate (specific inhibitor of the process of sulfate reduction). Survival in (near) anoxic seawater of Chamelea was studied in a static system by comparing untreated seawater with autoclaved seawater and untreated clams with clams incubated in well-aerated seawater, containing the broad-spectrum antibiotic chloramphenicol, prior to the anoxic survival test. With untreated clams and natural seawater (median mortality time 2.4 days) a decrease in pH and exponential accumulation of sulfide and ammonium was observed in the anoxic medium, indicating excessive growth of (sulfate reducing) bacteria. In sterilized seawater LT50 (2.1 days) was not significantly different and again considerable amounts of ammonium and sulfide accumulated. However, pre-treatment of clams with chloramphenicol resulted in an increase of LT50 (11.0 days) by approximately fivefold. Accumulation of ammonium and sulfide was retarded, but was finally even stronger than in the medium containing untreated clams. Median mortality times were 2.5 and 2.4 days for Chamelea and 2.7 and 2.9 days for Cerastoderma for static and flow-through incubations, respectively. Addition of chloramphenicol increased strongly survival time in both systems with corresponding values of 11.0 and 16.3 days for Chamelea, and 6.4 and 6.5 days for Cerastoderma. LT50 of Scapharca in anoxic seawater was 14.4 days. Chloramphenicol and penicillin increased median survival time to 28.5 and 28.7 days, respectively, whereas polymyxin displayed no effect (LT50=13.6 days). Molybdate added to artificial sulfate free seawater blocked biotic sulfide formation, but did not improve survival time (LT50=13.7 days). Overall the results indicate that proliferation of anaerobic pathogenic bacteria, firmly associated with the bivalves, is a main cause of death besides lack of oxygen. Bacterial damage is probably caused by injury of the tissues of the clams and not by the release of noxious compounds to the medium.

Abstract
Reaction of the methylcyclopentadienyl (Cp') cluster compound [(eta(5)-Cp')(3)Mo(3)S(4)][pts] (pts = p-toluenesulfonate) with noble metal alkene complexes resulted in the formation of four new heterobimetallic cubane-like Mo(3)S(4)M' cluster cores (M' = Ru, Os, Rh, Ir). Thus, reaction with [(1,5-cod)Ru(CO)(3)] or [(1,3-cod)Os(CO)(3)] (cod = cyclooctadiene) afforded [(eta(5)-Cp')(3)Mo(3)S(4)M'(CO)(2)][pts] (M' = Ru: [1][pts]; M' = Os: [2][pts]). When [1][pts] was kept in CH(2)Cl(2)/pentane solution, partial loss of carbonyl ligands occurred and the carbonyl-bridged dicubane cluster [((eta(5)-Cp')(3)Mo(3)S(4)Ru)(2)(mu-CO)(3)][pts](2) was isolated. An X-ray crystal structure revealed the presence of the hitherto unobserved Ru(mu-CO)(3)Ru structural element. The formation of cluster compounds containing Mo(3)S(4)Rh and Mo(3)S(4)Ir cores was achieved in boiling methanol by reacting [(eta(5)-Cp')(3)Mo(3)S(4)][pts] with [M'Cl(cyclooctene)(2)](2) (M' = Rh, Ir) in the presence of PPh(3). In this way [(eta(5)-Cp')(3)Mo(3)S(4)M'Cl(PPh(3))][pts] (M' = Rh, Ir) could be isolated. An alternative route to the Mo(3)S(4)Rh cluster core was found in the reaction of [(eta(5)-Cp')(3)Mo(3)S(4)][pts] with [RhCl(1,5-cod)](2), which yielded [(eta(5)-Cp')(3)Mo(3)S(4)Rh(cod)][pts](2) ([7][pts](2)). Substitution of the cod ligand in [7][pts](2) by 1,3-bis(diphenylphosphanyl)propane (dppp) gave [(eta(5)-Cp')(3)Mo(3)S(4)Rh(dppp)][pts](2).

Abstract
The main aim of this study was to compare the effects of bilateral 6-OHDA lesion of the prefrontal, frontal and media cerebral cortex, with those of suction ablation of the same areas, upon apomorphine and amphetamine evoked behaviors. Twenty five cats were distributed in four groups: 1) 8 cats received bilateral, injection of 6-OHDA (32 micrograms per hemisphere), and the behaviors elicited by separate injection of apomorphine (2.0 mg/kg s.c.) and amphetamine (2.5 mg/kg s.c.) before and after the lesion were compared; 2) 3 cats received a unilateral injection of 6-OHDA into the cited areas and dopamine concentration on the lesioned site and the contralateral non-lesioned side were compared; 3) 8 cats had bilateral suction ablation of the cited cortical areas and the results of apomorphine and amphetamine evoked behaviors before and after ablation were compared, and 4) the effects of solvent injections and sham operations were studied in 6 additional cats. 6-OHDA lesion had scanty effects on the behaviors evoked by apomorphine and amphetamine. Only two (fear like behavior and lack of food motivation) out of 9 behaviors elicited by apomorphine were modified, while two of five behaviors elicited by amphetamine (immobility and food motivation) showed a change. On the other hand, the ablation procedure had a much wider effect on the behaviors elicited by the dopaminergic agonist drugs. All 5 behaviors evoked by amphetamine were modified, while only 4 of nine behaviors induced by apomorphine did change. These results show the importance of the interplay between dopamine and the target tissue that receive the dopaminergic fibers in the production of the behaviors evoked by parenteral injection of apomorphine and amphetamine.

Abstract
Among 70 patients referred for suspected multiple sclerosis (MS) a total of 40 met criteria for definite (17), likely (12) or possible (11) diagnosis of the disease. Visual evoked potentials provided evidence of CNS lesion in 13 cases. Abnormalities of somatosensory evoked potentials, particularly on stimulation of the posterior tibial nerve, were present in 90% of patients. Brainstem auditory evoked potentials were of little use, contributing to diagnosis of one subclinical lesion; they were normal in 14 cases with suspected brainstem involvement. A definite diagnosis of MS was made in 4 cases by study of oligoclonal bands. The most frequently involved sites were the optic nerve and the brainstem, followed by the spinal cord. Hemispheral location was demonstrated in only 3 cases. These findings of the first study on MS in our country suggest a different pattern for demyelinating diseases in Chile.

Abstract
Of the 87 cases of Creutzfeldt-Jakob disease (CJD) ascertained in Chile since 1931, 39 are familial accounting for 45% of all cases, and 25% of the 51 definite cases. There are 11 affected families with an average of 3.5 affected members per family, and a rate of occurrence consistent with autosomal dominant transmission. There is no evidence for maternal lineage, and age at death is not significantly different from that of sporadic cases. About half of the cases died around the same age, suggesting some form of vertical transmission. Three pairs of affected members in 3 different families died at the same time, possibly indicating common exposure to CJD agent. The study of absolute death intervals and temporal and spatial separations between affected members suggests minimum incubation periods ranging from 2 to 37 years, assuming case-to-case transmission. CJD occurring in a woman related by marriage to one of the affected families strongly argues for horizontal transmission. The high proportion of familial CJD observed in Chile is probably the result of both a genetically determined susceptibility to the CJD virus, and a high degree of case ascertainment. However, the present study leaves unanswered the mode of transmission of the agent within the affected families.

Abstract
We determined the concentrations of IgA, IgG, and C3 in spinal fluid and IgA, IgG, IgM, and C3 in serum from seven patients with histologically revified Creutzfeldt-Jakob disease. The mean total protein content in spinal fluid was significantly higher than in controls. The increased mean concentrations of IgA, IgG, and C3 in spinal fluid, and their respective mean percentages in spinal fluid, suggest a passage of IgG and C3 from blood into spinal fluid, and a possible production of IgA within the central nervous system.

Abstract
Forty patients with histologically proved intracranial tumors were submitted to preoperative lumbar and venous punctures. The concentration of alpha-1-antitrypsin in the serum and in cerebrospinal fluid was determined by radial immunodiffusion technique. In the series, both serum and cerebrospinal fluid alpha-1-antitrypsin concentrations are significantly higher than the mean normal values. No statistical differences are observed in serum alpha-1-antitrypsin levels between benign and malignant tumors, but cerebrospinal fluid alpha-1-antitrypsin is significantly increased in the group of malignant tumors if cases undergoing steroid treatment are excluded. The diagnostic value of alpha-1-antitrypsin determinations in groups of patients with intracranial tumors is suggested.
