Abstract
Mastitis is one of the most significant diseases in dairy cows and causes several economic losses. Somatic cell count (SCC) is often used as an indirect diagnostic tool for mastitis, especially for subclinical mastitis (SCM) where no symptoms or signs can be detected. Streptococcus agalactiae is one of the main causes of contagious mastitis, and Prototheca spp. is an alga-inducing environmental mastitis that is not always correlated with increased milk SCC. The aim of this study was to evaluate the changes in the metabolomic profile of blood in relation to subclinical intramammary infection (IMI) in dairy cows. In addition, differences resulting from the etiologic agent causing mastitis were also considered. Forty Holstein-Friesian dairy cows in mid and late lactation were enrolled in this cross-sectional design study. Based on the bacteriological examination of milk, the animals were divided into 3 groups: group CTR (control group; n = 16), group A (affected by SCM with IMI caused by Strep. agalactiae; n = 17), and group P (affected by SCM with IMI caused by Prototheca spp.; n = 7). Blood samples from the jugular vein were collected in tubes containing clot activator; the serum aliquot was stored until metabolomic analysis by 1H-nuclear magnetic resonance spectroscopy. Statistical analysis was conducted by fitting a linear model with the group as the fixed effect and SCC as the covariate. Forty-two metabolites were identified, and among them 10 were significantly different among groups. Groups A and P showed greater levels of His and lactose and lower levels of acetate, Asn, and dimethylamine compared with group CTR. Group A showed high levels of Val, and group P showed high levels of Cit and methylguanidine, as well as lower levels of 3-hydroxybutyrate, acetone, allantoin, carnitine, citrate, and ethanol. These metabolites were related to ruminal fermentations, energy metabolism, urea synthesis and metabolism, immune and inflammatory response, and mammary gland permeability. These results suggest systemic involvement with subclinical IMI and that the metabolic profile of animals with SCM undergoes changes related to the etiological agent of mastitis.

Abstract
Metabolic disorders as ketosis are manifestations of the animal's inability to manage the increase in energy requirement during early lactation. Generally, buffaloes show a different response to higher metabolic demands than other ruminants with a lower incidence of metabolic problems, although ketosis is one of the major diseases that may decrease the productivity in buffaloes. The aim of this study was to characterize the metabolic profile of Mediterranean buffaloes (MB) associated with 2 different levels of β-hydroxybutyrate (BHB). Sixty-two MB within 50 days in milk (DIM) were enrolled and divided into 2 groups according to serum BHB concentration: healthy group (37 MB; BHB <0.70 mmol/L; body condition score: 5.00; parity: 3.78; and DIM: 30.70) and group at risk of hyperketonemia (25 MB; BHB ≥0.70 mmol/L; body condition score: 4.50; parity: 3.76; and DIM: 33.20). The statistical analysis was conducted by one-way ANOVA and unpaired 2-sample Wilcoxon tests. Fifty-seven metabolites were identified and among them, 12 were significant or tended to be significant. These metabolites were related to different metabolic changes such as mobilization of body resources, ruminal fermentations, urea cycle, thyroid hormone synthesis, inflammation, and oxidative stress status. These findings are suggestive of metabolic changes related to subclinical ketosis status that should be further investigated to better characterize this disease in the MB.

Abstract
BACKGROUND Despite increasing use of next-generation sequencing (NGS), data concerning the gain in germline pathogenic variants (PVs) remain scanty, especially with respect to uncanonical ones. We aimed to verify the impact of different cancer predisposition genes (CPGs) on colorectal cancer (CRC) in patients referred for genetic evaluation. MATERIALS AND METHODS We enrolled for NGS, by Illumina TruSight Cancer panel comprising 94 CPGs, 190 consecutive subjects referred for microsatellite instability (MSI) CRC, polyposis, and/or family history. RESULTS Overall, 51 (26.8%) subjects carried 64 PVs; PVs coexisted in 4 (7.8%) carriers. PVs in mismatch repair (MMR) genes accounted for one-third of variant burden (31.3%). Four Lynch syndrome patients (20%) harbored additional PVs (HOXB13, CHEK2, BRCA1, NF1 plus BRIP1); such multiple PVs occurred only in subjects with PVs in mismatch syndrome genes (4/20 versus 0/31; P = 0.02). Five of 22 (22.7%) patients with MSI cancers but wild-type MMR genes harbored PVs in unconventional genes (FANCL, FANCA, ATM, PTCH1, BAP1). In 10/63 patients (15.9%) with microsatellite stable CRC, 6 had MUTYH PVs (2 being homozygous) and 4 exhibited uncanonical PVs (BRCA2, BRIP1, MC1R, ATM). In polyposis, we detected PVs in 13 (25.5%) cases: 5 (9.8%) in APC, 6 (11.8%) with biallelic PVs in MUTYH, and 2 (3.9%) in uncanonical genes (FANCM, XPC). In subjects tested for family history only, we detected two carriers (18.2%) with PVs (ATM, MUTYH). CONCLUSION Uncanonical variants may account for up to one-third of PVs, underlining the urgent need of consensus on clinical advice for incidental findings in cancer-predisposing genes not related to patient phenotype.

Abstract
Objectives Colorectal cancer (CRC) screening with a faecal immunochemical test (FIT) has
been disrupted in many countries during the COVID-19 pandemic. Performing
catch-up of missed screens while maintaining regular screening services
requires additional colonoscopy capacity that may not be available. This
study aimed to compare strategies that clear the screening backlog using
limited colonoscopy resources. Methods A range of strategies were simulated using four country-specific CRC
natural-history models: Adenoma and Serrated pathway to Colorectal CAncer
(ASCCA) and MIcrosimulation SCreening ANalysis for CRC (MISCAN-Colon) (both
in the Netherlands), Policy1-Bowel (Australia) and OncoSim (Canada).
Strategies assumed a 3-month screening disruption with varying recovery
period lengths (6, 12, and 24 months) and varying FIT thresholds for
diagnostic colonoscopy. Increasing the FIT threshold reduces the number of
referrals to diagnostic colonoscopy. Outcomes for each strategy were
colonoscopy demand and excess CRC-related deaths due to the disruption. Results Performing catch-up using the regular FIT threshold in 6, 12 and 24 months
could prevent most excess CRC-related deaths, but required 50%, 25% and
12.5% additional colonoscopy demand, respectively. Without exceeding usual
colonoscopy demand, up to 60% of excess CRC-related deaths can be prevented
by increasing the FIT threshold for 12 or 24 months. Large increases in FIT
threshold could lead to additional deaths rather than preventing them. Conclusions Clearing the screening backlog in 24 months could avert most excess
CRC-related deaths due to a 3-month disruption but would require a small
increase in colonoscopy demand. Increasing the FIT threshold slightly over
24 months could ease the pressure on colonoscopy resources.

Abstract
Recently, a certain number of broiler abattoirs located in different Countries around the World have signaled an emerging quality issue termed "gaping" because of the separation of the fiber bundles affecting the external portion of the bipinnate pectoralis minor muscle. Thus, after defining the criteria to classify the muscles as Normal (NORM), Moderate (MOD), or Severe (SEV) cases, the incidence of gaping under commercial conditions was assessed on a total of 8,600 P. minor obtained from broiler chickens belonging to 43 flocks during a 6-mo period. Then, a total of 180 P. minor were selected based on previously defined criteria to evaluate the main quality traits (pH, color, water-holding/-binding capacity and tenderness), proximate composition, water mobility, and thermal properties as well as metabolic profile through 1H-Nuclear Magnetic Resonance spectroscopy. The average incidence of gaping defect was found to be 16.8% (8.8 and 8.0% MOD and SEV cases, respectively). As for the main quality traits, a reduction in ultimate pH was observed as the severity of the gaping defect increased, with SEV muscles displaying significantly lower values in comparison with NORM (5.96 vs. 6.02; P < 0.01), while MOD showed intermediate values (5.99). Concurrently, if compared with their NORM counterpart, MOD and SEV exhibited higher lightness (53.6 and 54.2 vs. 51.8; P < 0.01) coupled with higher (P < 0.05) cooking losses and longer (P < 0.05) transversal relaxation time of extra-myofibrillar water fraction. Overall, no significant differences were found concerning proximate composition and thermal properties. With regard to the metabolic profile, a significantly lower (P < 0.001) glutamine concentration was found in MOD and SEV muscles that, concurrently, revealed significant (P < 0.05) variations in the metabolites involved in energy-generating pathways. Overall, these findings evidenced that the gaping defect affecting broilers' P. minor muscles have strong similarities with the pale-soft-exudative condition previously described in poultry and likely results from the biochemical processes taking place during the post-mortem conversion of muscle to meat.

Abstract
Symptomatic uncomplicated diverticular disease (SUDD) affects 50% of people having diverticulosis. We performed a pilot study assessing the effect of current treatments on fecal microbiota and metabolome in SUDD. Thirteen consecutive females with SUDD were treated with a 2-week therapeutic trial of 30 g/day fiber supplementation (3 patients), 1.6 g/day of mesalazine (3 patients), 900 billion/day of probiotic mixture VivoMixx® (3 patients), or 800 mg/day of rifaximin (4 patients). Stool samples were collected at entry (T0), at the end of the 2-week therapeutic course (T1), and 30 (T2) and 60 days (T3) after the end of the therapeutic course. Real-time PCR quantified targeted microorganisms. Fecal metabolome patterns were studied by high-resolution proton NMR spectroscopy. At cumulative analysis, symptoms significantly decreased at each time point during follow-up (p less than 0.0001), and only left-lower quadrant pain increased again at T3. The overall bacterial quantity was not altered by the treatments. The amount of Akkermansia muciniphila species was significantly reduced at T1 (p=0.017) and at T2 (p=0.026), while at T3 the reduction was not significant in comparison to enrollment (p=0.090). Fecal molecular profile showed significant changes at T1 and T2, while at T3 it became similar to that of T0. Differences were found for 18 of the quantified molecules (tryptophan, phenylalanine, tyrosine, 4-hydroxyphenylacetate, urocanate, X-6.363, X-5.779, uridylate, galactose, X-4.197, threonine, sarcosine, methionine, 2-oxoisocaproate, 5-aminolevulinate, alanine, leucine, valerate). Metabolome and microbiota changed in patients with SUDD under treatment, confirming a possible role of dysbiosis/dysmetabolome in the pathology.

Abstract
In this study, we sought to find novel bacterial and metabolic hallmarks for bacterial vaginosis (BV). We studied the vaginal microbiome and metabolome of vaginal fluids from BV-affected patients (n = 43) and healthy controls (n = 37) by means of an integrated approach based on quantitative polymerase chain reaction (qPCR) and proton nuclear magnetic resonance ((1)H-NMR). The correlations between the clinical condition and vaginal bacterial communities were investigated by principal component analysis (PCA). To define the metabolomics signatures of BV, 100 discriminant analysis by projection on latent structure (PLS-DA) models were calculated. Bacterial signatures distinguishing the health condition and BV were identified by qPCR. Lactobacillus crispatus strongly featured the healthy vagina, while increased concentrations of Prevotella, Atopobium and Mycoplasma hominis specifically marked the infection. (1)H-NMR analysis has led to the identification and quantification of 17 previously unreported molecules. BV was associated with changes in the concentration of metabolites belonging to the families of amines, organic acids, short chain fatty acids, amino acids, nitrogenous bases and monosaccharides. In particular, maltose, kynurenine and NAD(+) primarily characterised the healthy status, while nicotinate, malonate and acetate were the best metabolic hallmarks of BV. This study helps to better understand the role of the vaginal microbiota and metabolome in the development of BV infection. We propose a molecular approach for the diagnosis of BV based on quantitative detection in the vaginal fluids of Atopobium, Prevotella and M. hominis, and nicotinate, malonate and acetate by combining qPCR and (1)H-NMR.

Abstract
BACKGROUND In pancreatic ductal adenocarcinoma (PDAC), fractalkine receptor CX3CR1 contributes to perineural invasion (PNI). We investigated whether CX3CR1 expression occurs early in PDAC and correlates with tumour features other than PNI. METHODS We studied CX3CR1 and CX3CL1 expression by immunohistochemistry in 104 human PDAC and coexisting Pancreatic Intraepithelial Neoplasia (PanIN), and in PdxCre/LSL-Kras(G12D) mouse model of PDAC. CX3CR1 expression in vitro was studied by a spheroid model, and in vivo by syngenic mouse graft of tumour cells. RESULTS In total, 56 (53.9%) PDAC expressed CX3CR1, 70 (67.3%) CX3CL1, and 45 (43.3%) both. CX3CR1 expression was independently associated with tumour glandular differentiation (P=0.005) and PNI (P=0.01). Pancreatic Intraepithelial Neoplasias were more frequently CX3CR1+ (80.3%, P<0.001) and CX3CL1+ (86.8%, P=0.002) than matched cancers. The survival of PDAC patients was better in those with CX3CR1+ tumour (P=0.05). Mouse PanINs were also CX3CR1(+) and -CL1(+). In vitro, cytokines significantly increased CX3CL1 but not CX3CR1 expression. Differently, CX3CR1 was upregulated in tumour spheroids, and in vivo only in well-differentiated tumours. CONCLUSION Tumour differentiation, rather than inflammatory signalling, modulates CX3CR1 expression in PanINs and PDAC. CX3CR1 expression pattern suggests its early involvement in PDAC progression, outlining a potential target for interfering with the PanIN transition to invasive cancer.

Abstract
Background: Aberrant activation of the canonical WNT signaling is a feature of colorectal cancer (CRC). Van-Gogh-like 2 (VANGL2) belongs to the non-canonical WNT pathway whose activation inhibits canonical WNT signaling. In this study, we investigated the role of VANGL2 and its epigenetic regulation in CRC. Methods: Van-Gogh-like 2 expression and promoter methylation after 5-aza-2′-deoxycytidine (5-aza) treatment were evaluated in CRC cells. DNA samples from 418 sporadic CRCs were tested for VANGL2 promoter methylation and microsatellite instability (MSI). Proliferation, colony formation and activation of the WNT pathway were tested in cells after VANGL2 overexpression. Results: Van-Gogh-like 2 mRNA was significantly higher in 5-aza-treated RKO, LOVO and SW48, whereas no differences were found in SW480. Van-Gogh-like 2 was fully methylated in RKO, SW48, HCT116, DLD1 and Caco2; partially methylated in LOVO, LS174T and SW837; and unmethylated in SW480, SW620 and HT29. Higher expression of VANGL2 mRNA was found in the unmethylated cell lines. In CRC specimens (8.93% MSI), methylated VANGL2 was associated with MSI, higher grade, proximal colon location and BRAF mutation. Van-Gogh-like 2 overexpression in SW480 significantly decreased proliferation, colony formation and β-catenin levels. Conclusion: Van-Gogh-like 2 is frequently methylated in MSI-CRCs with BRAF mutation and may act as a tumour suppressor gene, counteracting WNT/β-catenin signaling.

Abstract
The accuracy of thermal conductivity measurements is even more requested for materials
characterization in energy-efficient buildings field. ENEA-UTTMATF and CertiMaC research
group, as national institute and private laboratory respectively, cooperate in development
of new measurement and analysis methods applied to buildings materials and their
performances. For what concerns this kind of measurements, an Heat Flow-meter Transducer
(HFT) is used. In order to give to both customers and other research institutes involved
in the same field (e.g. International Comparison or International Round Robin Tests) the
most exhaustive evaluation of the tested material thermal conductivity, a complete
uncertainty analysis is implemented on the HFT measures. This uncertainty analysis,
developed accordingly to the international standards and with the contribution of INRiM
Institute, is described in this paper.

Abstract
Hypertriglyceridaemia is a common dyslipidaemia encountered in clinical practice. People with hypertriglyceridaemia are frequently obese, insulin-resistant, hypertensive or diabetic, all of which are risk factors for cardiovascular diseases. Hypertriglyceridaemia also contributes to metabolic syndrome, in which an atherogenic diet, sedentary lifestyle, overweight/obesity and genetic factors interact. A multi-factorial intervention for all risk factors is necessary, including weight reduction, dietary modification and increased physical exercise. This review focuses on the influence of diet, sedentary lifestyle and negative habits (such as excessive alcohol intake, smoking and drug addiction) on hypertriglyceridaemia as well as the effects of lifestyle change.

Abstract
Microsatellite instability (MSI) originates from the systematic accumulation of uncorrected deletion/insertion in repetitive DNA tracts in cancer cells with a deficient mismatch repair system. Among colorectal cancers, the MSI signature identifies hereditary cases arising in patients with germline mutations in hMLH1, hMSH2, PMS2 and a fraction of those with hMSH6 mutations, as well as sporadic cancers with epigenetic hMLH1 promoter hypermethylation. Considering the specific pathogenesis, pathological features, natural history and response to 5-fluoro-uracil-based chemotherapy of the MSI cancers, confusion about the genetic markers for MSI recognition seems surprising. In this clinically relevant field, an agreement has not been reached concerning the use of di- or mononucleotide markers for MSI assessment. The Revised Bethesda Guidelines still recommend a panel of markers consisting of mono- and dinucleotides, despite being questioned whether it is congruous to continue to use dinucleotide markers for MSI identification. In any event, no single marker is accurate enough for MSI testing, and an awareness of their pros and cons is required for proper interpretation of results. In recent years, several papers have reported different prevalence of MSI in unrelated series, largely depending on the detection and classification method, suggesting that MSI test interpretation also requires the understanding of the phenomenon rather than simply the crude satisfaction of panel recommendations. Inaccuracies can otherwise lead to under- or overdiagnosis and inaccurate disease classification, which always have a negative impact on the clinical practice of medicine.

Abstract
BACKGROUND Albuminuria is the best and most readily available marker for glomerular damage and progressive renal function loss in patients with diabetic nephropathy. Recently, administration of the oral glycosaminoglycan sulodexide (a mixture of 80% fast-moving heparin and 20% dermatan sulphate) was shown to effectively decrease albumin excretion rate in diabetics with nephropathy. AIMS To evaluate whether the hypoalbuminuric effect of sulodexide is associated with improvement of the renal vascular or tubule function. METHODS Forty-five type 1 diabetic patients, affected by diabetic nephropathy with albuminuria for at least 5 years, were randomly allocated to sulodexide or untreated. Those allocated to sulodexide were given 100 mg of sulodexide daily for 120 days. Renal vascular function (DIR) and N-acetyl-beta-D-glucosaminidase (NAG) excretion were estimated before and at the end of the study, the former in thesulodexide group only. DIR was measured as two Cr(cl) lasting 120 min (before and during 2 mug/kg b.w. i.v. dopamine). RESULTS The analysis of trends during the study demonstrated a marked reduction of albuminuria in the sulodexide group (from 126.1 +/- 15.41 to 93.6 +/- 13.7 mg/day). DIR rose from 13.2 +/- 2.1% to 15.44 +/- 1.9% (relative increase: +16.9%), and NAG excretion showed a decreasing trend decreased in the sulodexide group only (from 5.1 +/- 0.62 to 4.7 +/- 0.40 U/g(creat)). CONCLUSION The findings presented in this study indicate for the first time that orally available sulodexide may favorably affect the renal vascular function in type 1 diabetic patients with nephropathy and microalbuminuria. The effect of sulodexide on NAG is strongly influenced by the baseline NAG values, with a significant NAG reduction in the patients with the highest baseline NAG values.

Abstract
Colorectal cancer (CRC) develops as multistep process, which involves genetic and epigenetic alterations. K-Ras, p53 and B-Raf mutations and RASSF1A, E-Cadherin and p16INK4A promoter methylation were investigated in 202 CRCs with and without lymph node and/or liver metastasis, to assess whether gene abnormalities are related to a metastogenic phenotype. K-Ras, B-Raf and p53 mutations were detected in 27, 3 and 32% of the cases, with K-Ras mutations significantly associated with metastatic tumour (P=0.019). RASSF1A, E-Cadherin and p16INK4A methylation was documented in 20, 44 and 33% of the cases with p16INK4A significantly associated with metastatic tumours (P=0.001). Overall, out of 202 tumours, 34 (17%) did not show any molecular change, 125 (62%) had one or two and 43 (21%) three or more. Primary but yet metastatic CRCs were prevalent in the latter group (P=0.023) where the most frequent combination was one genetic (K-Ras in particular) and two epigenetic alterations. In conclusion, this analysis provided to detect some molecular differences between primary metastatic and nonmetastatic CRCs, with K-Ras and p16INK4A statistically altered in metastatic tumours; particular gene combinations, such as coincidental K-Ras mutation with two methylated genes are associated to a metastogenic phenotype.

Abstract
BACKGROUND It is controversial whether CARD15 variants are truly associated with a more severe form of Crohn's disease. The relative role of CARD15 genotype and smoking in Crohn's disease progression is also debated. AIM To investigate the association between CARD15 variants and history of resective surgery in patients with Crohn's ileal disease, taking into account smoking as a possible confounding factor. METHODS We originally assessed CARD15 genotype in 239 north Italian Crohn's disease patients (mean follow-up: 10.1 +/- 8.1 years). We then focused on 193 patients with proven ileal involvement, 70 of whom (36.3%) carried CARD15-mutated alleles (G908R, R702W, L1007fs). RESULTS Carriage of CARD15 variants was positively associated with family history and ileal-only disease and negatively associated with uncomplicated behaviour at maximal follow-up (P < 0.05). Ileal resection was the only variable independently associated with CARD15 variants at multivariate analysis (OR 3.8; 95% CI 1.6-9.2; P = 0.003). Kaplan-Meier analysis showed that ileal resection was favoured both by CARD15 variant-carriage (P = 0.01) and by smoking (P = 0.05), but smoking did not affect progression to surgery in variant carriers (P = 0.31). Thirteen of 14 (93%) patients being resection-free at 15-year follow-up, had CARD15 wild-type genotype (P = 0.01), whereas only seven (50%) had never smoked (P = 1.0). CONCLUSIONS In summary, CARD15 variant-associated Crohn's ileitis is virtually committed to stricturing and/or penetrating disease and, eventually, to resective surgery. Smoking accelerates progression to surgery in patients with wild-type CARD15 genotype, but it seems to exert no additional effect in CARD15-variant carriers.

Abstract
OBJECTIVE To describe the effect of Coenzyme Q10 (CoQ10) (added to either a fibrate, or polyunsaturated fatty acids (PUFA) or association of both) in patients affected by massive hypertriglyceridemia (MHTG) resistant to fibrates and PUFA. DESIGN Open, sequential, comparative intervention study. SETTING Specialised centres for dyslipidemia management. SUBJECTS Fifteen subjects (mean age: 45.1+/-12.5 years) affected by MHTG and hyporesponsive to either fibrates, or PUFA, or fibrates-PUFA association, and 15 age-matched subjects regularly responders to PUFA and fenofibrate treatment. INTERVENTIONS Treatment for periods of 6 weeks each with the following consecutive treatments: CoQ10 150 mg/day, PUFA 3000 mg/day, fenofibrate 200 mg/day, PUFA 3000 mg/day+fenofibrate 200 mg/day, PUFA 3000 mg/day+CoQ10 150 mg/day, fenofibrate 200 mg/day+CoQ10 150 mg/day, and finally, fenofibrate 200 mg/day+PUFA 3000 mg/day + CoQ10 150 mg/day. RESULTS CoQ10 supplementation did not improve any monitored parameter in the control group except for systolic and diastolic blood pressure, creatinine and Lp(a) plasma levels, both during fenofibrate and/or PUFA treatment. In MHTG group, CoQ10 supplementation significantly improved TG, TC, Lp(a), uric acid and blood pressure during fenofibrate treatment, but only Lp(a) and blood pressure during PUFA treatment. Fenofibrate appeared to have better effect on hsCRP and gamma-GT plasma levels than PUFA. No significant change was observed in any group and under any treatment in regards to homocysteinemia, PAI-1, or t-PA. CONCLUSION Even though the mechanism of action through which the effects were obtained is yet to be elucidated, adding CoQ10 to fenofibrate could improve the drug's efficacy in MHTG patients not responding to fenofibrate alone.

Abstract
NSCLC rates among the most frequent and lethal neoplasm world-wide and a significant decrease in morbidity and mortality relies only upon effective early diagnostic strategies. We investigated K-ras mutations and p16(INK4A) hypermethylation in tumor tissue and sputum of 50 patients with NSCLC and correlated them with sputum cytology and with tumor staging, grading and location, to ascertain, in sputum, their potential diagnostic impact. The same genetic/epigenetic abnormalities and cytological features were also evaluated in sputum from 100 chronic heavy smokers. Genetic analysis identified molecular abnormalities in 64% tumors (14/50 K-ras mutations and 24/50 p16(INK4A) hypermethylation) and in 48% sputum (11/50 K-ras mutations and 16/50 p16(INK4A) hypermethylation). In tumors K-ras mutations and p16(INK4A) hypermethylation were mostly mutually exclusive, being found in the same patients in 3 cases only. Genetic abnormalities in sputum were detected only in molecular abnormal tumors. Molecular changes in sputum had rates of detection similar to cytology (42%) but the cyto-molecular combination increased the diagnostic yield up to 60%. Interestingly, the rate of detection of genetic changes in sputum of tumors at early stage (T1) was not significantly different from that of tumors at more advanced stage (T2-T4). In fact K-ras point mutations were frequently recognised in tumors at early stage while p16(INK4A) inactivation prevailed in tumors at advanced stage ( P=0.0063). As expected, diagnostic cytological findings were more frequently found in tumors at advanced stage (P=0.004). No correlation was found between tumor grading and location (central versus peripheral) and molecular changes. p16(INK4A) hypermethylation, but not K-ras mutations, was documented in sporadic cases of asymptomatic heavy smokers (4%) where it was uncoupled from cytological abnormalities. In conclusion the cyto-molecular diagnostic strategy adopted in this study was able to detect the majority of tumors but in order to be proposed as effective and early diagnostic tool, this molecular panel needs to be tested in prospective studies with adequate follow-up.

Abstract
Colorectal adenomas can be morphologically classified as exophytic or flat. Polypoid cancers and cancers arising de novo (ie., without any adenomatous component) might be the results of genetic progression from exophytic and flat adenomas, respectively. In this study, we examined 94 morphologically distinct neoplastic specimens for mutations in K-RAS and analyzed 10 microsatellite loci tightly linked to the tumor suppressor genes APC, p53, DCC/SMAD4, hMSH2, and hMLH1. K-RAS mutations were significantly associated with exophytic adenomas [11 of 21 (52%)] compared to flat adenomas [2 of 13(15%), P < 0.03] and polypoid cancers [17 of 25 (68%)] compared to cancers arising de novo [7 of 25 (28%), P < 0.01]. Two polypoid cancer cases demonstrated three and four different K-RAS mutations, respectively, suggesting multiple areas of clonal expansion. Cancers arising de novo were significantly associated with loss of heterozygosity (LOH) at chromosome 3p compared to pol ypoid cancers [6 of 18(33%) versus 1 of 20(5%), P < 0.03], whereas the prevalence of LOH at chromosomes 2p, 5q, 17p, and 18q and microsatellite instability were not different between the groups. For all cancers, LOH at chromosomes 17p and 18q occurred in 47 and 51%, respectively. However, LOH at 17p and 18q occurred in 0 and 16% of benign lesions, respectively, suggesting their role in malignant transformation. There was no difference in LOH at chromosomes 17p and 18q between exophytic and flat lesions. These findings suggest that (a) mutant K-RAS is associated with the exophytic growth of colonic neoplasms, and that (b) some colorectal cancers arising de novo lose chromosome 3p during their evolution, which is not seen in polypoid cancers. Half of all cancers lose chromosomes 17p and 18q at or near the malignant transition of benign lesions as reported previously, irrespective of morphology. There may be more than one genetic avenue for colorectal cancer formation, and this correlates with the morphological characteristics.

Abstract
JC virus (JCV), along with other members of the polyomavirus family, encodes a class of highly conserved proteins, T antigens, that are capable of inducing aneuploidy in cultured cells. We have previously isolated T-antigen DNA variants of JCV from both colon cancer tissues and the corresponding nonneoplastic gastrointestinal tissues, raising new questions about the role of JCV in the development of chromosomal instability of the colon. Based on the sequence of the transcriptional control region (TCR), JCV can be classified as archetype or tandem repeat variants. Among the latter, Mad-1, the prototype virus first isolated from a patient with progressive multifocal leukoencephalopathy, is characterized by lacking the 23- and 66-bp sequences that are present in the archetype and by duplication of a 98-bp sequence. In this study, we evaluated differences in the TCR of JCV isolated from colon cancer tissues and nonneoplastic epithelium. To characterize JCV variants, we first treated eight pairs of DNA samples from colon cancers and noncancerous tissue with topoisomerase I and then amplified and cloned the JCV TCR. We obtained 285 recombinant clones from the JCV TCR, 157 from nonneoplastic samples, and 128 from colon cancer tissues. Of these clones, 262 spanned the length of the JCV Mad-1 TCR: 99.3% from nonneoplastic samples and 82.8% from colon cancer tissues. In sequencing 54 clones in both directions, we did not find archetype JCV either in the nonneoplastic tissue or in the cancer samples. From all colon cancer tissues, 18 clones had a deletion of one 98-bp tandem repeat. This deleted strain was not detected in any of the nonneoplastic tissues (14 versus 0% [chi(2) = 23.6; P < 0.001]). Our study demonstrates that the only JCV strain present in the human colon is Mad-1, and the variant with a single 98-bp sequence is found exclusively in the cancer tissues. This strain may be involved in the development of chromosomal instability.

Abstract
A truncating mutation (C to T transition) at codon 531 of the human protooncogene c-src, possibly accounting for the activation of c-src tyrosine kinase, has been recently identified in a subset of advanced colorectal cancer from North-American patients. However, two subsequent studies have failed to confirm the occurrence of SRC 531 mutation in colorectal cancers from North-European and Asiatic patients, raising the hypothesis that the genetic activation of src in colon cancer might be restricted to patients belonging to specific ethnic groups. We investigated a large series of colorectal cancers from Italian patients (155 cases) with a high prevalence of liver metastasis (43%). Using a PCR-RFLP assay, the occurrence of a SRC 531 mutation was ruled out in all the investigated specimens of primary tumours and/or metastases. Our results demonstrate that SRC Gln531AMB plays no role in the development or in the progression of colorectal cancer among Italian patients.

Abstract
BACKGROUND & AIMS JC virus (JCV), a human polyomavirus, has been found in a limited number of normal human tissues and cancers. The oncogenic potential of this virus is mediated by a transforming protein, the T antigen (TAg). We have previously demonstrated the presence of JCV-TAg in colorectal cancers, in adjacent normal colonic mucosa from these patients, and in the human colon cancer cell line SW480. The mode of transmission of this virus is unclear, and we hypothesized that the gastrointestinal (GI) tract may be a reservoir for the virus. METHODS DNA was extracted from 129 normal GI tissue samples collected from 33 patients. Topoisomerase I-assisted polymerase chain reaction (PCR) was used to detect the virus using exact and degenerate primers. Nested PCR and Southern blot analysis confirmed the identity of the PCR products. Single-stranded conformation polymorphism (SSCP) analysis and sequencing were used to evaluate the presence of viral quasispecies. RESULTS JCV sequences were found in 75.8% of patients (70.6% of upper GI and 81.2% of colonic samples); no significant differences in rates of infection were found by site. The use of degenerate primers combined with topoisomerase I treatment led to viral detection in 58.9% of samples, compared with 27.9% of samples using exact primers and topoisomerase I (P < 0.01). SSCP and sequencing analysis confirmed the amplification of viral quasispecies and the authenticity of TAg sequences. CONCLUSIONS The results show that JCV DNA sequences are highly prevalent in the human upper and lower gastrointestinal tract of immunocompetent individuals.

Abstract
Hepatocellular carcinoma (HCC) is usually preceded by cirrhosis whose genetic background is still poorly understood. The aim of this study was to evaluate, in non-end-stage cirrhosis, the fractional allelic loss (FAL) at loci mostly reported to be altered in HCC and the microsatellite instability (MSI). Twenty cases of cirrhosis were retrospectively selected. Eleven had developed an HCC during the follow-up (HCC-prone group), while 9 remained HCC-free (HCC-free group). Microdissected hepatocellular cirrhotic nodules from basal liver biopsies, were studied at 20 loci (on the chromosomal arms 1p and 1q, 3p, 4q, 6q, 7q, 8p, 13q, and 18q) and with the mononucleotide repeats BAT26 and TGFbIIR. Genetic changes were detected in both groups. Overall, the FAL index was statistically increased in the HCC-prone group (0.213) as compared to the HCC-free group (0.094; P =.044). Allelic loss at chromosomal arms 1p, 4q, 13q, 18q, and concurrent losses at more than 3 loci were confined to the HCC-prone group. In both groups, MSI was never ascertained using BAT26 and TGFbIIR. In conclusion, an increased FAL index and the lack of MSI characterize the non-end-stage cirrhosis of patients undergoing HCC during follow-up. These data emphasize the role of early clonal changes in chronic liver disease, and their potential predictive significance for clinical use.

Abstract
The multistep nature of cancer has been well-documented through molecular genetic studies of colorectal cancer. The information provided by basic, translational and clinical science highlighted several genes associated with different hereditary syndromes predisposing to colorectal cancer. Due to these and other findings, the molecular pathogenesis of this cancer has been clarified also with respect to genetic pathways which can lead to an otherwise undistinguishable disease. As a result of both the available and continuously added data, our knowledge and understanding of colorectal cancer is subject to constant changes. Ultimately, these are expected to result in multiple and strategical managements based on molecular genetics which will likely change our approach to this cancer in the incoming millennium.

Abstract
JC virus (JCV) is a polyoma virus that commonly infects humans. We have found T antigen DNA sequences of JCV in the mucosa of normal human colons, colorectal cancers, colorectal cancer xenografts raised in nude mice, and in the human colon cancer cell line SW480. A larger number of viral copies is present in cancer cells than in non-neoplastic colon cells, and sequence microheterogeneity occurs within individual colonic mucosal specimens. The improved yield of detection after treatment with topoisomerase I suggests that the viral DNA is negatively supercoiled in the human tissues. These results indicate that JCV DNA can be found in colonic tissues, which raises the possibility that this virus may play a role in the chromosomal instability observed in colorectal carcinogenesis.

Abstract
Our understanding of the pathogenesis of cancer has undergone a revolution over the past decade. Tumors develop by the accumulation of damage to genes that regulate cell growth. Many of the genes responsible for disregulation of cell growth have been identified, as have the processes that lead to the genetic damage. One of the most important concepts that has facilitated our understanding of carcinogenesis is that of genetic or "genomic" instability, which is required to permit a sufficient amount of genetic damage to accumulate to permit the neoplastic phenotype to emerge and evolve. Two mechanisms that lead to genomic instability--one of which involves the loss of chromosomal fragments from the nucleus, and a second which is characterized by microsatellite instability--are discussed.

Abstract
BACKGROUND & AIMS Hereditary nonpolyposis colorectal cancer (HNPCC) has been linked recently to a defect in repairing mismatched nucleotides in DNA. The aim of this study was to screen for germline mutations that result in prematurely truncated proteins in two of the mismatch repair genes identified at this time, hMLH1 and hMSH2, in a consecutive series of patients belonging to familial aggregations of colorectal cancer. METHODS Nineteen individuals with colorectal cancer from 19 families were consecutively referred because of a strong positive family history of colorectal cancer. Premature truncation mutations in hMLH1 and hMSH2 were sought from lymphocyte RNA by using an in vitro transcription/translation (IVTT) assay. RESULTS Protein truncating mutations in the hMLH1 or hMSH2 genes were found in 50% of families with HNPCC (6 of 12) but were not observed in any of the remaining familial aggregations that did not fulfill the standard criteria for HNPCC. In some of the IVTT-positive samples, the mutations were characterized by genomic sequencing. CONCLUSIONS IVTT may be a practical method to accomplish primary screening of germline mutations in DNA mismatch pair genes in HNPCC; however, a broader approach is necessary to obtain a more complete picture of the mutational spectrum in HNPCC and other familial aggregations of colorectal cancer.

Abstract
Semantic priming effects in naming Italian and English words were investigated. Experiments 1 and 2 were in Italian. In Experiment 1, the subjects named a target word, which was either associated with or unrelated to a preceding prime. The results showed semantic priming effects. However, in Experiment 2, in which the same materials occurred in a list that also included pseudowords, priming effects were obtained with the lexical decision task, but not with pronunciation. In Experiment 3, the inclusion of pseudowords in the materials prevented priming effects from occurring in Italian, but not in English. Finally, Experiment 4 indicated that, even in Italian, nonlexical reading was abandoned when a few of the to-be-pronounced items required lexical knowledge for correct stress assignment. The findings suggest that reading normally occurs lexically. The characteristics of the various writing systems, however, are relevant in determining the strategies that people may adopt in unusual circumstances.
