Abstract
The intrinsically disordered tau protein plays a pivotal role in the pathogenesis of Alzheimer's disease (AD) and other human tauopathies. Abnormal post-translational modifications of tau, such as truncation, are causally involved in the onset/development of these neurodegenerative diseases. In this context, the AD-relevant N-terminal fragment mapping between 26 and 44 amino acids of protein (tau26-44) is interesting, being endowed with potent neurotoxic effects in vitro and in vivo. However, the understanding of the mechanism(s) of tau26-44 toxicity is a challenging task because, similarly to the full-length tau, it does not have a unique 3D structure but exists as dynamic ensemble of conformations. Here we use Atomic Force Spectroscopy, Small Angle X-ray Scattering and Molecular Dynamics simulation to gather structural and functional information on the tau26-44. We highlight the presence, the type and the location of its temporary secondary structures and we unveil the occurrence of relevant transient tertiary conformations that could contribute to tau26-44 toxicity. Data are compared with those obtained on the biologically-inactive, reverse-sequence (tau44-26 peptide) which has the same mass, charge, aminoacidic composition as well as the same overall unfolded character of tau26-44.

Abstract
Many ocular diseases are associated with an alteration of the mechanical and the material properties of the eye. These mechanically-related diseases include macular hole and pucker, two ocular conditions due to the presence of abnormal physical tractions acting on the retina. A complete relief of these tractions can be obtained through a challenging microsurgical procedure, which requires the mechanical peeling of the internal limiting membrane of the retina (ILM). In this paper, we provide the first comparative study of the nanoscale morphological and mechanical properties of the ILM in macular hole and macular pucker. Our nanoscale elastic measurements unveil a different bio-mechanical response of the ILM in the two pathologies, which correlates well to significant differences occurring during microsurgery. The results here presented pave the way to the development of novel dedicated microsurgical protocols based on the material ILM properties in macular hole or pucker. Moreover, they contribute to clarify why, despite a common aetiology, a patient might develop one disease or the other, an issue which is still debated in literature.

Abstract
Glioblastoma (GBM) and meningothelial meningioma (MM) are the most frequent malignant and benign brain lesions, respectively. Mechanical cues play a major role in the progression of both malignancies that is modulated by the occurrence of aberrant physical interactions between neoplastic cells and the extracellular matrix (ECM). Here we investigate the nano-mechanical properties of human GBM and MM tissues by atomic force microscopy. Our measures unveil the mechanical fingerprint of the main hallmark features of both lesions, such as necrosis in GBM and dural infiltration in MM. These findings have the potential to positively impact on the development of novel AFM-based diagnostic methods to assess the tumour grade. Most importantly, they provide a quantitative description of the tumour-induced mechanical modifications in the brain ECM, thus being of potential help in the search for novel ECM targets for brain tumours and especially for GBM that, despite years of intense research, has still very limited therapeutic options.

Abstract
Colorectal cancer (CRC) development represents a multistep process starting with specific mutations that affect proto-oncogenes and tumour suppressor genes. These mutations confer a selective growth advantage to colonic epithelial cells that form first dysplastic crypts, and then malignant tumours and metastases. All these steps are accompanied by deep mechanical changes at the cellular and the tissue level. A growing consensus is emerging that such modifications are not merely a by-product of the malignant progression, but they could play a relevant role in the cancer onset and accelerate its progression. In this review, we focus on recent studies investigating the role of the biomechanical signals in the initiation and the development of CRC. We show that mechanical cues might contribute to early phases of the tumour initiation by controlling the Wnt pathway, one of most important regulators of cell proliferation in various systems. We highlight how physical stimuli may be involved in the differentiation of non-invasive cells into metastatic variants and how metastatic cells modify their mechanical properties, both stiffness and adhesion, to survive the mechanical stress associated with intravasation, circulation and extravasation. A deep comprehension of these mechanical modifications may help scientist to define novel molecular targets for the cure of CRC.

Abstract
We evaluated the effect of acupuncture on NSAID resistant dysmenorrhea related pain [measured according to Visual Analogue Scale (VAS)] in 15 consecutive patients. Pain was measured at baseline (T1), mid treatment (T2), end of treatment (T3) and 3 (T4) and 6 months (T5) after the end of treatment. Substantial reduction of pain and NSAID assumption was observed in 13 of 15 patients (87%). Pain intensity was significantly reduced with respect to baseline (average VAS = 8.5), by 64, 72, 60 or 53% at T2, T3, T4 or T5. Greater reduction of pain was observed for primary as compared with secondary dysmenorrhea. Average pain duration at baseline (2.6 days) was significantly reduced by 62, 69, 54 or 54% at T2, T3, T4 or T5. Average NSAID use was significantly reduced by 63, 74, 58 or 58% at T2, T3, T4 or T5, respectively, and ceased totally in 7 patients, still asymptomatic 6 months after treatment. Our findings suggest that acupuncture may be indicated to treat dysmenorrhea related pain, in particular in those subjects in whom NSAID or oral contraceptives are contraindicated or refused.

Abstract
The cow and its milk have been held sacred in the world since the dawn of human civilization. Indian ancient Vedic texts describe the virtues of milk and dairy products, as is authenticated by modern scientific principles and proofs. Therefore, milk has been considered as one of the most natural and highly nutritive part of a daily balanced diet. Currently, the integration of advanced scientific knowledge with traditional information is gaining incredible momentum toward developing the concept of potential therapeutic foods. Furthermore, new advances toward understanding the therapeutic roles of milk and milk products have also given a new impetus for unraveling the age old secrets of milk. At present, the best-known examples of therapeutic foods are fermented milk products containing health promoting probiotic bacteria. In the present article, we have tried to review the various aspects of the therapeutic nature of milk and fermented dairy products in a highly up-dated manner, and offer an in-depth insight into the development of targeted therapeutic future foods as per the requirements of consumers.

Abstract
The aim of the present study is to assess the clinical efficacy of a phytocompound with antimicotic properties (K-712, with the following 100 mg composition: 10 mg of oleoresin from Pseudowintera colorata at 30 percent concentration in Polygodial together with trace amounts of Olea europea) in recurrent vulvo-vaginal candidiasis (RVVC) as compared to an azole drug during a 12-month period: 6 months of treatment followed by 6 months of observation. This prospective randomized study involved 82 women (19-61 years) with complaints of abnormal vaginal discharge and with a history of at least four proven episodes of RVVC in the previous 12 months. Patients were divided into two groups of treatment of 41 patients each and were given: A) Itraconazole 200 mg orally daily for 4 days, then 200 mg once weekly for 6 months or B) 1 tablet twice a day of a K-712 for 4 weeks and then for the first 2 weeks of each month for a total of 6 months. Both groups were then followed-up for further 6 months. Each treatment schedule was well tolerated with only 4 patients in the azole group complaining of transient mild symptoms (nausea, abdominal discomfort, unpleasant taste). Itraconazole reached an earlier symptomatic relief during the first two weeks of observation as compared with K-712 (p<0.05) but both treatments enabled a comparable benefit during the entire treatment study period, afterwards with comparable symptom/sign score (itraconazole vs K-712: 9 vs 11). At 6-month observation, mycological cure was reached by 83 percent in the itraconazole group and in 78 percent of the K-712-treated patients. During the further 6-month observation period without treatment, the itraconazole group showed significantly more relapses (65.7 vs 34.2 in K-712, p<0.05) and at the end of the whole 12-month study period the mycological cure was significantly higher in the K-712-treated patients (65.8 vs 34.3 percent, p<0.05). There was a non- significant trend increase of less drug-susceptible species in the itraconazole group. From these preliminary data it would appear that a natural antifungal phytocompound proves to be as good as itraconazole in the maintenance treatment of RVVC. Moreover, this approach seems to maintain a higher mycological success rate afterwards by reducing the number of relapses and probably of the growth of azole-resistant species.

Abstract
There is a great concern for the increasing incidence of candidiasis in cancer patients following immune-suppressive, cytostatic or antibiotic treatment. There are cancer patients with repeat asymptomatic recovery of candida in the urine in whom the choice of treatment, if any, is still a matter of debate. The aim of the study is to test the efficacy and tolerability of a natural anti-fungal phytocompound in patients with tumors of the gastrointestinal tract with prior or ongoing candiduria. Thirty-nine patients with operated gastrointestinal malignancies (18 still under current chemotherapy) with a history of repeated candiduria were enrolled. Eleven patients showed candiduria on enrolment and were treated with K-712, a natural antifungal phytocompound. Genomic analysis was carried out on blood samples of all patients on a monthly basis for 6 months. Within 3 weeks all 11 treated patients had negative cultures in the urine (10 patients after 2 weeks), 7 patients remained free of candiduria throughout the study period while 4 required a new treatment course. Three patients had positive genomic tests for systemic candidiasis and were treated with fluconazole. Eighteen (64 percent) out of the 28 patients who were free of candiduria on enrolment, developed a urinary candida infection during the 6-month follow-up and all cases were successfully treated with K-712. Seven (38 percent) of these cases presented a further recurrence at a later stage and all responded to a new course of K-172. No positive genomic tests were observed during the follow-up period. These data suggest that a consistent part of patients, mostly with gastrointestinal malignancies develop urinary candida infection when following chemotherapy treatment. A therapeutic approach with a natural antifungal phytocompound seems a safe and effective measure and a tentative prophylactic approach might also be envisaged.

Abstract
Diabetic nephropathy (DN) is a severe and life-threatening complication of long-standing diabetes. As one of the main causes of end-stage renal disease, the prevention and treatment of DN in early stage, and the slowing down of DN progression are of utmost importance and are topics of several ongoing research studies. Nutraceuticals endowed with antioxidant-anti-inflammatory properties may offer an opportunity of integrative treatment for this condition. Male Wistar rats were randomly assigned to two groups. One group of rats (diabetic group) received a single tail-vein injection of STZ compound (50 mg/kg) under light anaesthesia. A protective dose of 0.5 ml of 5 percent dextrose was given intraperitoneally 30 min before the administration of STZ. One diabetic group was fed a normal pellet diet (group A) while group B was fed the diet added with DTS (panax pseudoginseng, eucommia ulmoides), (Kyotsu Jigyo, Tokyo, Japan) in the proportion of 50/25 (percent weight/weight), at the dose of 50 mg/kg/day throughout the experimental period. At the end of 8 weeks, 24-hour urine was collected for the measurement of the albumin concentration: blood samples were collected for serum biochemistry and the rats were sacrificed for kidney measurement of oxidative stress and histomorphological features. Nephrin and Macrophage Chemoattractant Protein-1 (MCP-1) gene expression were also assessed by fluorescence real-time quantitative PCR after RNA extraction and cDNA synthesis. STZ-treated animals showed significantly increased in lipid peroxidation in the kidney and in proteinuria. DTS supplementation did not affect plasma glucose but significantly decreased malonyldialdehyde (MDA) plasma level and the overall redox parameters together with a partial mitigation of proteinuria. Histological analysis showed also that DTS significantly reduced the glomerular volume together with glomerulosclerosis and interstitial fibrosis score (p less than 0.05), the latter two being correlated to proteinuria (p less than 0.05). DTS supplementation also enabled a reduction of diabetes-induced decrease of nephrin mRNA expression and a 67 percent reduction of MCP-1 mRNA up-regulation (p less than 0.01). Taken altogether, these data show that, besides the mandatory control of glycemia, intervention with a nutraceutical with antioxidant and anti-inflammatory properties may have beneficial effects when integrated in the mainstream of the therapeutic regimen.

Abstract
Human breast cancer cell lines MCF-7 (ER-positive) and Hs578T (ER-negative) were cultured and one lot incubated for 48 h with 5-50 mug/ml of a fermented phytocompound (MK: Manda-Koso, Innoshima, Japan). In vitro, it appeared a dose-dependent decrease of cell viability (5-57%) in MK group in both cell lines (P < 0.001, plateau: 30 microg/ml), decreased beta-galactosidase activity, enhanced apoptosis, and inversely increased Bax/Bcl2 ratio (P < 0.01) with an upregulation of p53 (P < 0.05). In the in vivo model, Balb-c mice were inoculated with tumor cells and the treatment group was fed with 20 mg of MK. Tumor weight in MK-fed group was time-course reduced by 22% to 51% at 2 and 4 weeks, respectively (P < 0.05) with increased survival (P < 0.05). Tumour tissue of MK-fed mice showed a downregulated Bcl-2 with increased Bax/Bcl-2 ratio, reduced PCNA, and activated caspase 3. Although more studies are ongoing to foster the clinical applicability of MK integrated within a rational chemopreventive and therapeutic strategy, a p53-mediated mechanism is likely to play a relevant role, besides its reported antioxidant capacity, NK cell activity enhancement, cancer-cytostatic activity properties.

Abstract
The aim of this study was to test the combined effect of a quality-controlled red clover extract (RCE) standardized to contain 40% isoflavones by weight (genistein, daidzein, biochanin A, and formononetin present as hydrolyzed aglycones) together with a modified alkaline supplementation on bone metabolic and biomechanical parameters in an experimental model of surgically-induced menopause. Sprague-Dawley female rats were maintained under controlled standard conditions of light and fed with conventional food of standard calcium content and no alfalfa or soybean components. Rats were randomized into four groups: Group A represented normal rats (sham operated) while three other groups were ovariectomized (OVX) and fed for three months as follows: standard food (group B), 6 mg/kg/day food mixed with RCE (Group C), or given 6 mg/kg/day of RCE plus a modified alkaline supplementation (BP) through a nasogastric tube at a dose of 16 mg (group D). The animals were killed 90 days after surgery. As compared to group B, RCE or RCE + BP treatments brought about significantly higher level of estradiol and mitigated the weight loss of the uterus and improved maximum load of the femoral neck. Osteocalcin level showed an over 65% increase in group B but both RCE and RCE + BP treatments prevented such abnormality with a significantly better result in RCE + BP group which virtually normalized such parameter as well as urinary excretion of DPD. Group C and D reduced the over 20% loss of bone mineral density and bone mineral content/body weight ratio observed in untreated post-ovariectomy group. Untreated ovariectomy caused about 48% decrease of cancellous bone mass in the femoral neck while this abnormality was prevented at similar extent by both RCE and RCE + BP treatments. Ovariectomy determined an over 80% increase of bone alkaline phosphatase (BALP) level but both RCE and RCE + BP treatments significantly mitigated such variable. The BALP decrease yielded by the combined RCE + BP treatment was statistically lower than RCE alone. Taken together these data show that red clover preparation in dosages amenable to clinical practice do improve OVX-induced osteoporosis while a mild metabolic alkalosis might further synergize some therapeutic aspects.

Abstract
In order to prevent and control non-communicable diseases (NCDs), the 61st World Health Assembly has endorsed an NCD action plan (WHA resolution 61.14). A package for essential NCDs including chronic respiratory diseases (CRDs) has also been developed. The Global Alliance against Chronic Respiratory Diseases (GARD) is a new but rapidly developing voluntary alliance that is assisting World Health Organization (WHO) in the task of addressing NCDs at country level. The GARD approach was initiated in 2006. GARD Turkey is the first comprehensive programme developed by a government with all stakeholders of the country. This paper provides a summary of indicators of the prevalence and severity of chronic respiratory diseases in Turkey and the formation of GARD Turkey.

Abstract
This study aims to determine the effects of a high protein diet and alkaline supplementation on bone metabolic turnover in rats. Eight-week-old male Sprague-Dawley rats were investigated by bone status, including bone mineral density (BMD) and biomechanical markers from blood and urine. Thirty rats were randomly divided into three groups and treated for 8 weeks as follows: baseline control group (n. 10, C), high-protein supplemented diet group (n. 10, chronic acidosis, CA group) and supplemented chronic acidosis (n.10, SCA). Diet-treated rats were fed an acidic high-protein diet and the supplementation consisted in a modified alkaline formula (Basenpulver, NaMed, Italy). At the end of the experimental period, the rats were sacrificed, blood samples were drawn and femur and tibia were removed for analysis of bone mineral density (BMD) by dual energy X-ray absorptiometry (DEXA). In the CA group, 24-hour urinary calcium (Ca) and phosphorus (P) excretion were increased 2.1-fold (p<0.05 vs normal diet controls) as well as kidney weight. However, serum Ca and P concentration, as well as urinary Dpd excretion were not significantly changed. Femural and tibial BMD was significantly decreased in the CA group (p<0.05), but alkaline supplementation prevented such phenomenon (p<0.05 vs CA). These results suggest that blood Ca and P concentrations in chronic acidosis condition during the 12-week supplementation might be maintained by hypercalciuria and hyperphosphaturia at the expenses of bone structure. However, modified alkaline supplementation is able to prevent such derangements.

Abstract
The aim of this study was to investigate the effects of the herbal compound YHK on hepatocarcinogenesis induced by diethylntrosamine (DEN) in Sprague Dawley rats. Rats were randomly divided into 3 groups and followed up for 15 weeks. Groups 1 was given standard food and represented the healthy control. Liver preneoplastic foci were induced using the DEN method in groups 2 and 3 (20 rats each). However, group 3 was concomitantly given 50mg/kg/day of YHK. For quantitative assessment of liver preneoplastic foci, the placental form of glutathione-S-transferase (GST-P) positive foci were measured using immunohistochemical staining and image analysis. Treatment using DEN caused a significant decrease in body weight and increase in liver weight compared to the control group while concomitant supplementation with YHK prevented body weight loss and liver weight increase. As compared to DENonly treated rats, the group given YHK showed a significant decrease in the number, size and volume of GSTP- positive foci. Moreover, co-administration of YHK significantly reduced the incidence, number, size and volume of hepatocellular carcinoma. Anti-inflammatory, anti-fibrotic as well as antioxidative properties of this compound are mechanisms which are likely to be advocated for to explain its protective effect. It is concluded that herbal compound YHK by preventing hepatocarcinogenesis in DEN-induced liver preneoplastic lesions in rats has the potential to a large clinical application as a functional food.

Abstract
Twenty-month-old Swiss mice were allocated into three groups: (A) control; (B) infected group; and (C) infected but treated with 5 mg of the phytocompound MMT. Mice were infected intranasally with 30 microL of 75 HA viral units. MMT markedly blunted the nasal signs of virus infection and the febrile response. Formazan-positive cells, lung and plasma lipoperoxides, and TNF-alpha in lung tissue increased during viral infection, but improvement was seen in the MMT-treated group (P < 0.05). MMT also normalized SOD, catalase activities, and ascorbic acid and determined a significant decrease of lung but not nasal viral titer, although nasal inflammatory infiltrate dropped significantly. MMT has potential clinical applications with and has an excellent safety profile even in old animals.

Abstract
T-maze test-selected prematurely senescent mice (PSM) were allocated into two groups: (A) those given DTS (150 mg/kg) orally for 30 days and (B) untreated PSM with age-matched fast T-maze performers as control. After sacrifice, the liver and kidney were analyzed for catalase (CAT) activity, glutathione peroxidase (GPx), superoxide dismutase (SOD), malondyaldehyde (MDA), and plasma thiols. Untreated PSM showed decreased plasma thiols and tissue level of CAT, SOD, GPx, with higher MDA (P < 0.01 vs. fast performers), while DTS (Denshichi-Tochiu-Sen) significantly improved glutathione and cysteine (P < 0.05) and tissue concentration of the above parameters (P < 0.05). Such preliminary data suggest that DTS mitigated oxidative damage in PSM, with likely action on the cytoplasm and mitochondrial matrix.

Abstract
OBJECTIVE The aim of the present study was to test the hypothesis that protein-calorie malnutrition aggravates the gut translocation of Candida albicans triggered by mesenteric ischemia-reperfusion (IR) injury in an experimental model while testing a natural product containing the antifungal anethole/polygodial mixture (Kolorex). METHODS MFI strain white mice (n = 90) were randomly allocated to a 4-week dietary regimen: (1) standard pellet diet containing 25% casein; (2) low-protein (2.5%) casein diet; (3) as group 2 plus oral supplementation with 20 microL of a 5% solution of Kolorex during the last 4 days. Twenty rats from each of these groups (termed 1a, 2a and 3a) were orally inoculated with Candida suspension 6 h prior to mesenteric IR injury. Animals of each group but without Candida inoculation (termed 1b, 2b and 3b) served as control. A colon permeability study was carried out as well. Rats were killed prior to the IR injury and 3 h afterwards. Control rats were killed at the same time. RESULTS Over 60% of the mesenteric lymph nodes and 30% of kidney samples were positive for C. albicans in the low-protein-fed rats after IR injury. Kolorex significantly decreased that rate of positivity and also significantly reduced the concentration of C. albicans per gram of each positive tissue sample examined. Protein-calorie malnourished animals showed a statistically significant increase in colon permeability and this phenomenon further increased after IR injury. The groups of rats treated with Kolorex compound showed a partial, although significant, improvement of this parameter. CONCLUSIONS These results suggest that Kolorex might exert a competitive effect against with C. albicans colonization. The present study represents the first experimental in vivo investigation of the anethole/polygodial-containing compound under the specific conditions of calorie-protein malnutrition and the results have potential clinical interest.

Abstract
Motility recording of small and large intestine was performed in old Wistar rats divided into three groups: (a) standard diet, (b) standard diet plus a symbiotic preparation, and (c) standard diet plus a heat-inactivated symbiotic preparation. SCM-III. significantly increased the myoelectric activity of small intestine and colon (p < 0.01 versus [a] and [c]) paralleling "young" values of 4-month-old rats and increased the spike burst frequency in the proximal-distal colon (p < 0.05). SCM-III significantly increased the frequency and duration of spike bursts in the jejunum, transverse-distal colon, and defecation frequency, while decreasing the intervals of migrating motor complex in the colon (p < 0.01) to "young" values with an increased mRNA expression of VIP (p < 0.05). Gut flora manipulation aimed to modulate myoelectric activity can tentatively help reversing age-related motility decay.

Abstract
OBJECTIVE Metals undergo redox cycling and there is increasing evidence of free radical generation and oxidative injury in the pathogenesis of liver injury and fibrosis in metal storage diseases. The aim of the present study was to test a natural hepatoprotective compound in metal-induced liver injury. METHODS Hepatocytes were isolated from Wistar rats by collagenase perfusion method and cultured as such and also with alpha-linolenic acid (LNA)-bovine serum albumin (BSA). Hepatocytes were then cultured with a graded dilution of PN-M001 (100 microg/mL and 200 microg/mL), which is a curcuma/absinthium-containing compound, or sylibin (100 microg/mL) dissolved in dimethyl sulfoxide for 10 min before the addition of metallic salts (iron, copper and vanadium). Lysosomal fractions were prepared for lysosome fragility tests in which beta-galactosidase activity and lactate dehydrogenase (LDH) leakage were measured, as well as oxidative damage tests in the presence of hydrophilic and lipophilic free radical generators. Quenching activity by 1,1-diphenyl-2-picrylhydrazyl (DPPH) was also assessed. RESULTS Malonildialdehyde accumulation in the medium showed a direct time-course increase with incubation time. Both PN-M001 and sylibin showed a significant protective effect against all challenge metal ions, as expressed by the half inhibition concentration (IC(50)) against lipid peroxidation. However, on a molar ratio, sylibin seemed to be more effective than PN-M001 in Fe-induced peroxidative damage (P < 0.05). Both test compounds, irrespective of the concentration, significantly reduced the LDH and beta-galactosidase concentration in the lysosomal fractions. As compared with untreated lysosomal fractions challenged with the two peroxide radicals generators, either PN-M001 or sylibin exerted significant protection However, PN-M001 was significantly better than sylibin in suppressing acid phosphatase enzyme activity. Both compounds showed comparable and significant DPPH radical-scavenging activity. CONCLUSION These data support the potential clinical application of curcumin-containing compounds.

Abstract
BACKGROUND/AIMS A number of studies have suggested a key role played by certain resident gut bacteria in the development of large bowel cancer. The aim of the present study was to test the effect of a novel symbiotic preparation, which has been recently shown to beneficially modify gut ecosystem and systemic immunity, on either preneoplastic and neoplastic changes in a colon carcinogenesis model. METHODOLOGY Sprague-Dawley rats were fed a standard diet for 1 week and then were randomly assigned to three groups. The control diet was given to groups A and B, whereas in group C, the same diet plus 2 mL of a probiotic mixture was given throughout the experiment. Thirty rats (groups B, C) each received a weekly subcutaneous injection of azoxymethane at a dose of 15 mg/kg of body weight for 10 weeks. Group A served as a control group and received a subcutaneous injection of saline for 10 weeks. Forty-five rats were sacrificed at 3-week observation and 60 rats at 20-week observation for assessing metaphase index together with aberrant crypt foci and intestinal immune system markers from one hand and tumor occurrence from the other, respectively. RESULTS Group A showed a significantly increased metaphase index either in aberrant crypt foci or in "normal appearing" crypts when compared to group A (p < 0.01). Group B rats caused a significant decrease at both sites (p < 0.05). The numbers of lymphocytes derived from the mesenteric lymph nodes in group B rats were significantly decreased (p < 0.01) as compared to either control and to group C. The percentage of CD8 lymphocytes in group C was significantly higher than that in group B. Group C showed a significantly reduced ratio of aberrant crypt foci/colon and of aberrant crypt per colon and per each single focus (p < 0.05). A total of 18 (90%) group B and 10 (50%) group C rats had colon tumors, this difference was significant. The mean number of colon tumors per rat was 2.2 and 1.0 in group B and C, respectively. CONCLUSIONS Effective probiotics treatment, through mechanisms still to be fully elucidated (decreased fecal pH, specific reduction of carcinogenetic bacterial enzymes, modulation of gut-associated and systemic immune system etc.) has the potential to exert significant antimutagenic properties against colon cancer.

Abstract
Using existing systems for appraising the efficacy of various therapies, regardless of their typology, the authors considered approximately 10 methods commonly used to evaluate quality of life. They provide guidelines on how to build another index for judging quality of life, taking into account the patient's conditions of life. These indexes share similar problems in finding objective measures for assessing personal situations without regard to patients' or observers' subjective impressions. Nevertheless, the authors demonstrate that for randomized controlled clinical trials and for meta-analyses this deficiency is also a problem, at least qualitatively, for scientific methods that are considered quite objective. Therefore, according to the methodological manifesto of the World Health Organization, the authors conclude by suggesting the simultaneous adoption, for complementary medicine studies, of some methods already known for their use in conventional medicine, despite general limited validity.

Abstract
Individuals exchange contracts for the delivery of commodities in competitive markets and, simultaneously, act strategically; actions affect utilities across individuals directly or through the payoffs of contracts. This encompasses economies with asymmetric information. Nash-Walras equilibria exist for large economies, even if utility functions are not quasi-concave and choice sets are not convex, which is the case in standard settings; the separation of the purchase from the sale of contracts and the pooling of the deliveries on contracts guarantee that the markets for commodities clear.

Abstract
Cytogenetic analysis performed on 73 sporadic basal cell carcinomas (BCCs) and three squamous cell carcinomas (SCCs) showed different findings in direct preparations (24 hours) and in short-term cell cultures. Except for loss of the Y chromosome, not one of the other clonal (+6, +16, add(2)(q37), del(3)(q13), add(1)(p31), and near triploidy) or sporadic changes found in direct preparations was found in cell cultures and vice versa. Clonal trisomy 6 found in two BCC direct preparations and demonstrated by interphase fluorescence in situ hybridization in 8 other cases seems to be a nonrandom change in basal cell carcinoma. Immunohistochemistry showed that the cell type investigated was different in the two methods of analysis used: epithelial in direct preparations and fibroblastic in cell cultures. Thus, the results obtained in direct preparations indicate the BCC or SCC epithelial karyotype, whereas the aberrations found in cell cultures indicate the presence of chromosome instability in the fibroblastic stroma. The apparent lack of correspondence between direct and indirect preparations and the presence of clonal chromosome changes in both epithelial and stromal cells suggest tumor cell heterogeneity of BCC. The fibroblastic stroma seems to be implicated in the neoplastic process. This is not evident in SCC, in which clonal changes are present only in direct preparations. The chromosomal distribution of the breakpoints involved in structural changes in direct and cell culture preparations is random; together with those reported in the literature, the breakpoints found in BCC cultures show, however, a cluster to 1p36, 3q13, 9q22, 14p11, 15p11, and Xp11 bands. We did not find any significant correlations between BCC cytogenetic results and the clinical data (site, age, sex, recurrence). The incidence of cases of BCC (38%) and of SCC (100%) showing clonal chromosome changes agree with their benign and malignant nature, respectively. Finally, a significantly high incidence of constitutional inv(9) and dup(9)(q11q21) was found in the group of patients with BCC.

Abstract
A new case of a de novo trisomy 10cen-->10pter is described. The karyotype was exactly defined by high resolution banding and FISH analysis; the chromosome aberration was of maternal meiotic origin as demonstrated by RFLP analysis. Clinical data are reported and correlated with other trisomy 10p cases from the literature. A critical review of the literature was made to define the phenotype of trisomy 10p syndrome.

Abstract
The results of cytogenetic and FISH analysis performed in 26 cases of Dupuytren contracture are reported. Clonal or sporadic chromosome changes were found in 18 cases (69%). Clonal changes consisted of: +2, +16, -10, -Y, add(1)(p23), del(2)(q21), t(3;16)(p21;q24), add (3)(p24), del(18)(q21), t(Y;14)(p12;q24), +mar. The results differ from those obtained in normal palmar fascia used as control, in which -Y and +Y were the only clonal changes found in 2 of 11 analyzed cases (18%). No clonal trisomy 8 was found. FISH analysis performed in 11 cases (centromeric probe specific for chromosome 8) failed to show the presence of a cell population with +8. Clonal and sporadic structural changes were different from case to case and no clustering breakpoint was observed. The significance of the chromosome instability leading to clonal and sporadic chromosome changes not specific to Dupuytren contracture are discussed.

Abstract
Benzodiazepine-like compounds are present in trace amounts in the blood of normal subjects and increase in liver cirrhotic patients with or without encephalopathy. Their increased presence may, however, represent an occasional precipitating factor of hepatic encephalopathy. The source of these compounds is still unknown, but they are constituents of our diet since benzodiazepine receptor ligands have been described in plants, vegetables and in animals. They may also be synthesized, at least in part, by intestinal bacterial flora. In this article we report that the level of these compounds in the blood decreased by 40% after therapy with rifaximin, which reduces the aerobic and anaerobic intestinal bacterial flora. This observation indicates that intestinal bacterial flora is involved in the production of these compounds and that repeated short-term medications with this non-absorbable antibiotic may be useful in reducing the levels of benzodiazepine-like compounds in patients with liver cirrhosis.

Abstract
Residues of three pesticides (dimethoate, parathion, and pyrazophos) in two artichoke cultivars, Masedu and Spinoso sardo, were investigated. The amount of pesticides in artichokes was greatly affected by the head shape. In the case of the calix-shaped Masedu artichoke, the residues in whole heads at commercial ripening were on average about twice higher than those of the pagoda-shaped Spinoso sardo artichoke. In the heart this ratio was 4 to 42 times greater. Residue decay rates were very fast, mainly owing to the dilution effect due to head growth.

Abstract
The T antigen (TAg) coding sequences of two DNA tumor viruses, BKV and SV40, were detected by Polymerase Chain Reaction (PCR) amplification followed by Southern-blot hybridization in two human glioblastoma multiforme derived cell lines. RT-PCR analysis indicated that these two TAg coding sequences were expressed in both tumor cell lines carrying the viral early region DNAs. Moreover, analytical polyacrylamide gel electrophoresis (PAGE) and DNA sequence analyses showed that the amplified PCR products are indistinguishable from the TAg coding sequences of BKV and SV40 wildtype strains. Cytogenetic study performed in the two cell lines showed unbalanced changes, mainly gains of chromosomes 3p, 5, 6, 7, and 19 and losses of chromosomes 3, 3q, 16, 9p22-->pter, 18, and 20. Excess of chromosomes 6 and 7 are common to the two cell lines. The putative role of the TAg of the two DNA tumor viruses in transformation and karyotype changes is discussed.

Abstract
Cytogenetic analysis was performed on 23 samples from non-neoplastic ureters. Clonal chromosome abnormalities were found in eight. They were: loss of Y chromosome, as a single abnormality (five cases) or associated with trisomy 10 and 20 (one case) or with trisomy 2 (one case); and duplication of Y chromosome (one case). Different numerical and structural sporadic abnormalities were found in nine cases. Immunohistochemical analysis and direct observation using the inverted microscope showed that the cells were mainly of the fibroblastic type. FISH analysis with chromosome 7 alpha-satellite probes failed to detect the presence of trisomy 7 in three epithelial cases tested.

Abstract
Metaphases from a cultured cerebral germ cell tumor (CGCT) in a boy with a 46,XY constitutional karyotype had 47 chromosomes with an additional X chromosome and a translocation (1;21)(q11;p11). CGCT appear to be nonrandomly associated with Klinefelter syndrome, and a supernumerary X chromosome and trisomy of the 1q21-->1qter region may be clonal abnormalities in these tumors. The predisposition of Klinefelter patients to develop CGCT may be due to the pathogenetic relevance of the extra X chromosome both as an acquired and a constitutional abnormality.

Abstract
Cytogenetic studies of benign prostatic hyperplasia (BHP) are scarce. We analyzed primary cell cultures obtained from biopsies of prostatic tissues from 10 patients (mean age: 60.7 years) with histologic diagnosis of BHP to compare the eventual chromosome changes with those reported in prostatic adenocarcinoma. Clonal chromosome abnormalities were noted in five of the 10 cases, with loss of Y chromosome in all. In one case, a clonal t(1;20) was observed with a -Y clone. Different numerical and structural sporadic abnormalities were evident in eight. Chromosome 1 was the chromosome most frequently involved in sporadic rearrangements. We concluded that -Y is a frequent nonrandom chromosome abnormality in BHP in this sample of patients. Immunohistochemical studies showed that loss of Y occurs in fibroblasts and not in epithelial cells; therefore, this anomaly is not related to cancer development.

Abstract
We analyzed the correlations between chromosome abnormalities and clinical and histopathologic characteristics in 77 cases of renal cell carcinoma (RCC). Chromosome changes such as +5,+7,+8,+10,+18,+X,+Y, and -Y have been excluded from the analysis because they also occur in nonneoplastic kidney tissue and cytogenetic analysis indicates that these anomalies are not involved in tumor progression. The most frequent specific chromosome abnormalities in this sample were 3p rearrangements, trisomy 17, and hyperdiploidy and were not related to tumor stage or grade or to development of distant metastases.

Abstract
Trisomy 7, trisomy 10 and loss of the Y chromosome have been found by some authors in presumptive normal parts of human kidneys. We describe cytogenetic findings in short-term cultures from 58 biopsies obtained from non-neoplastic and neoplastic (renal cell carcinoma, RCC) tissues from the same kidney, the same types of tissues from independent kidneys, and tissue from kidneys without neoplasia. The results indicate the following. Non-neoplastic tissue from kidneys involved in RCC have (in mosaics) trisomies 5, 7, 10, 18 and loss of the Y as non-random clonal changes. They are not the result of local metastasis but are also found in kidneys with non-tumoral chronic pathologies and should thus not be considered specific for RCC. They are neither culturing artefacts nor a general phenomenon found in cultured normal solid tissues, but are acquired abnormalities, possibly related to various reactive cellular states in the tissues that are histologically normal.

Abstract
Cytogenetic analysis of primary cell cultures from human atherosclerotic fibrous plaques revealed clonal chromosome abnormalities in 13 of the 18 cases studied. Loss of the Y chromosome and del(13)(q14) were present as single clonal abnormalities in eight cases; in five cases separate clones were found involving loss of the Y and a XXY karyotype, trisomy 10 and 18, loss of the Y and trisomy 7. A variety of single numerical and structural abnormalities were present in all but two of the 18 cases. Immunocytochemical studies were performed on cells from the same cultures used for cytogenetic analysis using monoclonal antibodies to human leucocyte common antigen, to human vimentin and to muscle actin. The immunoreactivity was positive for actin in 70-80% of the cells; 100% of the cells were positive for vimentin and all cells were ALC negative. These results indicated that the chromosomal abnormalities are present in the smooth muscle cells of the plaque. The hypothesis is proposed that the proliferation leading to the atherosclerotic lesion may primarily represent a hyperplastic response to mechanical and biological injuries and that this reactive proliferation is, in turn, associated with a tendency to chromosome instability.

Abstract
The correlations between cytogenetic and histopathological findings were analyzed in 65 cases of human meningiomas. Clonal chromosome abnormalities were present in 28 cases (43%). The overall female/male ratio was 1.7, but it was 1.1 in the group of 28 cases with chromosomal abnormalities. Abnormalities of chromosome 22 as sole abnormality predominate in the female patients. The mean age of patients with normal karyotype was significantly lower (50.7 years) than that of patients with chromosome changes (57.3 years). The tumor origin was predominantly at the base in the patients with normal karyotype but different at the convexity, falx cerebri, and spinal cord. The five abnormal cases from the spinal cord all showed involvement of chromosome 22. The proportion of chromosome anomalies was different in the various histological types, and a significant difference was found between the meningotheliomatous (23%) and psammomatous (58%) types. The cytogenetically abnormal cases of the psammomatous type all showed involvement of chromosome 22. In three patients with multiple meningiomas, we found different karyotypes in the different tumors of the same patient, which may indicate a multifocal origin of the tumors.
