Abstract
Lombardy has represented the Italian and European epicenter of the coronavirus disease 2019 (COVID-19) pandemic. Although most clinical efforts within hospitals were diverted towards the care of virally infected patients, therapies for patients with cancer, including radiotherapy (RT), have continued. During both the first and second pandemic waves, several national and regional organizations provided Italian and Lombardian RT departments with detailed guidelines aimed at ensuring safe treatments during the pandemic. The spread of infection among patients and personnel was limited by adopting strict measures, including triage procedures, interpersonal distance, and adequate implementation of personal protective equipment (PPE). Screening procedures addressed to both the healthcare workforce and patients, such as periodic nasopharyngeal swabs, have allowed the early identification of asymptomatic or pauci-symptomatic COVID-19 cases, thus reducing the spread of the infection. Prevention of infection was deemed of paramount importance to protect both patients and personnel and to ensure the availability of a minimum number of staff members to maintain clinical activity. The choice of treating COVID-19-positive patients has represented a matter of debate, and the risk of oncologic progression has been weighted against the risk of infection of personnel and other patients. Such risk was minimized by creating dedicated paths, reserving time slots, applying intensified cleaning procedures, and supplying personnel and staff with appropriate PPE. Remote working of research staff, medical physicists, and, in some cases, radiation oncologists has prevented overcrowding of shared spaces, reducing infection spread.

Abstract
Subclinical ketosis (SCK) may impair white blood cell (WBC) function and thus contribute to the risk of disease postpartum. This preliminary study investigated changes occurring in the immune system before disease onset to elucidate their role in the occurrence of SCK. A group of 13 Holstein dairy cows were housed in tie-stalls and retrospectively divided into 2 groups based on their levels of β-hydroxybutyrate (BHB) measured in plasma between calving day and 35 d from calving (DFC). Levels of BHB <1.4 mmol/L were found in 7 cows (control cows, CTR group) and levels >1.4 mmol/L were found in 6 cows at ≥1 of 6 time points considered (cows with SCK, KET group). From -48 to 35 DFC, body condition score, body weight, dry matter intake, rumination time, and milk yield were measured, and blood samples were collected regularly to assess the hematochemical profile and test the WBC function by ex vivo challenge assays. Data were submitted for ANOVA testing using a mixed model for repeated measurements that included health status and time and their interactions as fixed effects. Compared with CTR cows, KET cows had more pronounced activation of the immune system (higher plasma concentrations of proinflammatory cytokines, myeloperoxidase, and oxidant species, and greater IFN-γ responses to Mycobacterium avium), higher blood concentrations of γ-glutamyl transferase, and lower plasma concentrations of minerals before calving. Higher levels of nonesterified fatty acids, BHB, and glucose were detected in KET cows than in CTR cows during the dry period. The effect observed during the dry period was associated with a reduced dry matter intake, reduced plasma glucose, and increased fat mobilization (further increases in nonesterified fatty acids and BHB) during early lactation. A reduced milk yield was also detected in KET cows compared with CTR. The KET cows had an accentuated acute-phase response after calving (with greater concentrations of positive acute-phase proteins and lower concentrations of retinol than CTR cows) and impaired liver function (higher blood concentrations of glutamate-oxaloacetate transaminase and bilirubin). The WBC of the KET cows, compared with CTR cows, had a reduced response to an ex vivo stimulation assay, with lower production of proinflammatory cytokines and greater production of lactate. These alterations in the WBC could have been driven by the combined actions of metabolites related to the mobilization of lipids and the occurrence of a transient unresponsive state against stimulation aimed at preventing excessive inflammation. The associations identified here in a small number of cows in one herd should be investigated in larger studies.

Abstract
INTRODUCTION: Several efforts are being implemented at the European level to measure provision of up-to-date radiation treatments across the continent. METHODS: A snapshot survey involving all radiation oncology centers within Lombardy, Italy, was performed in 2012 and repeated in 2014 and 2016, in cooperation with regional governmental officers. Centers were asked to provide detailed information concerning all individual patients being treated on the index day, and to report data on available local resources. RESULTS: We observed an increase in the number of centers and of megavoltage units (MVU) (from 76 to 87, i.e., 8.7 MVU per million inhabitants in 2016). Mean number of MVU per center was 2.5. Average age of MVU increased from 5.3 to 7.5 years and patients on the waiting list also increased. Conformal 3D radiotherapy (RT) treatments decreased from 56% to 42% and were progressively replaced by intensity-modulated RT treatments (from 39% to 49%). Waiting times were overall satisfactory. Radiation oncologists treated on average 152 and radiation therapists 100 RT courses per year. Average reimbursement per course was €4,879 (range €2,476-€8,014). CONCLUSIONS: The methodology of snapshot survey proved feasible and provided valuable information about radiation oncology provision and accessibility in Lombardy.

Abstract
Primary lymphoma of the central nervous system (CNS) represents a pathology that is no longer considered rare, also in the light of its high correlation with the human immunodeficiency virus (HIV) syndrome reported recently. Often the correct diagnosis of the disease is difficult to reach, owing to the wide spectrum of non-lymphoma pathologies from which it should be differentiated and the invasiveness of some diagnostic techniques. The biologic aggressiveness of the neoplasm often makes a combined radio-chemotherapeutic approach necessary. In contrast, surgical resection does not seem to provide any significant benefit. The clinical experience reported here, together with a review of the most recent literature, lead the authors to suggest the opportunity of treating primary lymphoma of the CNS with the most active and modern chemotherapeutic protocols in association with traditional treatments to obtain an improvement in overall survival.

Abstract
Ovarian carcinoma is the fifth most common cause of death among women in western countries. It is often diagnosed in an advanced stage (FIGO Stage III and IV) and requires effective chemotherapy as first-line treatment. The advent of cisplatin combined with adriamycin and cyclophosphamide has remarkably increased the response rate in advanced disease. The authors report 31 cases of epithelial ovarian neoplasia, without prior chemotherapy, treated with cisplatin, adriamycin and cyclophosphamide (PAC I). Of the 30 evaluable patients, 15 had clinical complete remissions (cCR = 50%), 10 clinical partial remissions (cPR = 33%) and 5 no response (NR = 17%). The total response (cCR + cPR) was equal to 83%. Twelve of the 15 patients in cCR underwent second-look laparotomy; in 8 of these cases, histologic and cytologic confirmation of CR was obtained. PAC I was found to be a highly effective therapeutic regimen with moderate toxicity. The individual toxicity reported was gastroenteric (nausea and vomiting), but transitory. No chronic toxic side-effects from cisplatin or adriamycin were noted. However, more definitive results must be obtained to verify its impact on the prolongation of survival.

Abstract
We tested cadmium (Cd2+) effects on porcine IPEC-J2 cells, which represent an in vitro model of the interaction between intestinal cells and both infectious and non-infectious stressors. Accordingly, we investigated the effects of low (2 μM) to moderate (20 μM) concentrations of Cd2+, in terms of pro-inflammatory gene expression and protein release, as well as of infectivity in a Salmonella typhimurium penetration model. Our data showed a significant (P < .001) increase of intracellular Cd2+ after 3, 6 and 24 h of exposure with respect to levels at 1 h. These data showed the ability of IPEC-J2 to absorb Cd2+ as a function of both time and concentration. Also, the absorption of this heavy metal was related to a significant modulation of important pro-inflammatory messengers. In particular, down-regulation of IL-8 was associated with a significant decrease of Salmonella typhimurium ability to penetrate into IPEC-J2 cells, in agreement with a previous study in which an anti-IL 8 antibody could significantly inhibit Salmonella penetration into the same cells (Razzuoli et al., 2017). This finding demonstrates the ability of Cd2+ to affect the outcome of an important host-pathogen relationship. In conclusion, our study highlighted the ability of an environmental pollutant like Cd2+ to modulate innate immune responses in terms of chemokine release and gene expression, and susceptibility to microbial infections.

Abstract
The study was based on data collected during 5 yr (2003-2007) and was aimed at assessing the effects of the month, slaughter house of destination (differing for stocking density, openings, brightness, and cooling device types), length of the journey, and temperature-humidity index (THI) on mortality of heavy slaughter pigs (approximately 160 kg live weight) during transport and lairage. Data were obtained from 24,098 journeys and 3,676,153 pigs transported from 1,618 farms to 3 slaughter houses. Individual shipments were the unit of observation. The terms dead on arrival (DOA) and dead in pen (DIP) refer to pigs that died during transport and in lairage at the abattoir before slaughtering, respectively. These 2 variables were assessed as the dependent counts in separate univariate Poisson regressions. The independent variables assessed univariately in each set of regressions were month of shipment, slaughter house of destination, time traveled, and each combination of the month with the time traveled. Two separate piecewise regressions were done. One used DOA counts within THI levels over pigs transported as a dependent ratio and the second used DIP counts within THI levels over pigs from a transport kept in lairage as a dependent ratio. The THI was the sole independent variable in each case. The month with the greatest frequency of deaths was July with a risk ratio of 1.22 (confidence interval: 1.06-1.36; P < 0.05) and 1.27 (confidence interval: 1.06-1.51; P < 0.05) for DOA and DIP, respectively. The lower mortality risk ratios for DOA and DIP were recorded for January and March (P < 0.05). The aggregated data of the summer (June, July, and August) versus non-summer (January, March, September, and November) months showed a greater risk of pigs dying during the hot season when considering both transport and lairage (P < 0.05). The mortality risk ratio of DIP was lower at the slaughter house with the lowest stocking density (0.64 m(2)/100 kg live weight), large open windows on the roof and sidewalls, low brightness (40 lx) lights, and high-pressure sprinklers as cooling devices. The mortality risk ratio of DOA increased significantly for journeys longer than 2 h, whereas no relationship was found between length of transport and DIP. The piecewise analysis pointed out that 78.5 and 73.6 THI were the thresholds above which the mortality rate increased significantly for DOA and DIP, respectively. These results may help the pig industry to improve the welfare of heavy slaughter pigs during transport and lairage.

Abstract
OBJECTIVE The main aim of this work was to report on trabecular bone score (TBS) by dual-energy X-ray absorptiometry (DXA) of healthy Italian subjects to be used as a reference standard for future study in clinical and research settings. The secondary aim was to investigate the link between TBS and conventional parameters of bone and body composition by DXA. METHODS 250 individuals of 5 age bands (spanning from 18 to 70 years of age, equally distributed for both age and sex) were prospectively recruited. A lumbar spine (LS) DXA scan (Lunar iDXA™; GE Healthcare, Madison, WI) was acquired for each subject and then analysed with the latest version of TBS iNsight v. 2.1 (Med-Imaps, Pessac, France) software. LS bone mineral density (LS BMD), Z-score, T-score and TBS values were collected. Pearson's test was used to investigate the correlations between TBS and LS BMD and the influence of age, body mass index (BMI) and body composition on these parameters. RESULTS A significant decrease of TBS and LS BMD was observed with ageing in both males (TBS mean values from 1.486 to 1.374; LS BMD mean values from 1.219 to 1.187) and females (TBS mean values from 1.464 to 1.306; LS BMD mean values from 1.154 to 1.116). No statistically significant difference was achieved among males and females of the same age group for both TBS and LS BMD, with the exception of the fifth age group. A significant correlation was found between LS BMD and TBS values in both sexes (r = 0.555-0.655, p < 0.0001). BMI influenced LS BMD but not TBS. TBS values were inversely correlated with some fat mass parameters, in particular with visceral adipose tissue (in males: r = -0.332, p < 0.001; in females: r = -0.348, p < 0.0001). No significant correlation was found between TBS and total lean mass, opposite to LS BMD (in males: r = 0.418; p < 0.0001; in females: r = -0.235; p < 0.001). CONCLUSION This report is an attempt to start building a database for healthy Italian people providing age- and sex-specific reference curves for TBS. This could help clinicians to improve patient management in the detection of impaired bone mineral status and to monitor bone changes. ADVANCES IN KNOWLEDGE The study reports TBS values of a selectively enrolled Italian healthy population, ranging from younger to older ages and including males as a reference standard. Moreover, links between body composition and TBS are explored.

Abstract
A disease prediction system was investigated in a case-control study in the dry period of high-yielding dairy cows. Blood samples of 75 cows from 26 herds were collected before calving between -23 and -33 days (T1) and also between -2 and -6 days (T2) to investigate a panel of clinical immunology and chemistry parameters. Cows with abnormal serum lysozyme and interleukin-6 concentrations showed a greater disease prevalence until the 60th day in milk compared with non-responder cows (P<0.05 and lower at T1). Differences in disease prevalence were observed on the basis of T1 data, and also by combining the results at T1 and T2. The other laboratory parameters under study were not predictive of a disease risk. Results indicate that environmental stressors in the dry period may cause a negative imprinting of the innate immune response, underlying predisposition to later disease occurrence.

Abstract
Previous studies had indicated an active role of bovine forestomachs in the response to alimentary disorders as well as to inflammatory and infectious processes in both the gastro-intestinal (GI) tract and elsewhere. We investigated the potential of bovine forestomachs to receive, elaborate and produce signals and mediators of the innate immune response. Indeed, we detected the expression of Toll IL-1R8/single Ig IL-1-related receptor (TIR8/SIGIRR) and other receptors and cytokines, such as Toll-like receptor (TLR)4, interleukin (IL)-1β, IL-10 and Caspase-1 in the forestomach walls of healthy cows. Their presence suggests an active role of forestomachs in inflammatory disorders of the GI tract and other body compartments. Moreover, interferon (IFN)-γ was revealed in ruminal content. We confirmed and further characterized the presence of leukocytes in the rumen fluids. In particular, T-, B-lymphocytes and myeloid lineage cells were detected in the ruminal content of both rumen-fistulated heifers and diseased cows. An acidogenic diet based on daily supplements of maize was shown to inhibit leukocyte accumulation, as opposed to a control, hay-based diet, with or without a soy flour (protein) supplement. On the whole, results indicate that bovine forestomachs can receive and elaborate signals for the immune cells infiltrating the rumen content or other organs. Forestomachs can thus participate in a cross-talk with the lymphoid tissues in the oral cavity and promote regulatory actions at both regional and systemic levels; these might include the control of dry matter intake as a function of fundamental metabolic requirements of ruminants.

Abstract
Tonsils are secondary lymphoid organs that play an important role in host defense. The aim of our study was to develop reliable procedures for isolation and culture of pig tonsil cells, and to validate their possible use in functional immunoassays. Using our isolation procedure, we recovered on average 238.7 ± 107.1 × 10(6) cells per tonsil couple with a mean vitality of 89.8 ± 2.7%. These values significantly decreased 8 months after freezing at -80°C along with the subsequent spontaneous release of both IgA and IgG in culture. These results suggest to use pig tonsil cells within 2 months from thawing to maintain suitable conditions in terms of recovery, vitality and release of antibody in vitro. Tonsil mononuclear cells also showed the ability to secrete antimicrobial peptides and to respond in vitro to immunological stimuli. On the whole, our study has defined operating conditions for tonsil processing, control of bacterial contaminations, time limits of storage at -80°C, as well as for evaluating polyclonal Ig production in vitro. Such procedures are likely to be of some importance in studies on regional immunity and in the development of large animal models for biomedical sciences.

Abstract
The aim of this study was to investigate the effects of long-distance road transport (19 h, from Poland to Italy) during 2 seasons (summer vs. winter) on clinical and hematological variables in calves. The environmental temperature range that could compromise the thermoregulation system (thermal stress) of the calves was tested. For the 7 Holstein calves in each transport, the BW and rectal temperature (RT) were measured, and blood samples were collected at the farm of origin, before loading at the transit center (T2), after unloading at the farm of destination (T3), and 1, 2, 3, and 4 d after arrival. The body temperature (BT) and heart rate (HR) were continuously monitored from T2 to T3. The data were statistically analyzed according to a mixed model that considered the fixed effects of transport (repeated measurements), season of journey, and their interaction. Within the observed temperature-humidity index (THI) range (30 to 80), effective thermoregulation allowed the calves to maintain their BT with small physiologic changes to prevent thermal stress, particularly in the summer. With no seasonal differences, the HR was greater at loading than unloading (120 vs. 115 beats per min; P = 0.012). As for the transport effect, the BW was less (P < 0.001) after unloading, and the RT was greater (P = 0.004). This effect was more marked in summer. The hematological variables indicated a moderate effect of transport on the hydration condition, reactive and muscular systems, and metabolism, although hematocrit (P = 0.004), erythrocytes, cortisol, NEFA, β-hydroxybutyrate, lactate, creatine kinase, lactate dehydrogenase, and aspartate aminotransferase activity (P < 0.001), and total protein (P = 0.007) were greater after unloading. This was confirmed by a moderate decrease in total leukocytes (P = 0.031) and glucose concentration (P = 0.002). The changes in the clinical variables were similar for both seasons even though in the summer, hematocrit (P < 0.001), urea (P = 0.008), and total protein (P = 0.010) increased and glucose concentration (P = 0.038) decreased. In conclusion, the data did not show a pronounced effect attributable to the season of the journey. Long-distance road transport leads to notable changes in clinical and hematological variables at the end of the journey. However, these variables remained within their physiological ranges and returned to basal values within a few days after the journey.

Abstract
A few studies provided convincing evidence of constitutive expression of type I interferons (IFNs) in humans and mice, and of the steady-state role of these cytokines under health conditions. These results were later confirmed in pigs, too. In line with this tenet, low levels of IFN-α/β can be detected in swine tissues in the absence of any specific inducer. These studies are compounded by the utmost complexity of type I IFNs (including among others 17 IFN-α genes in pigs), which demands proper research tools. This prompted us to analyse the available protocols and to develop a relevant, robust, reverse transcription (RT) real-time polymerase chain reaction (PCR) detection system for the amplification of porcine IFN-α/β genes. The adopted test procedure is user-friendly and provides the complete panel of gene expression of one subject in a microtitre plate. Also, a proper use of PCR fluorochromes (SYBR(®) versus EvaGreen(®) supermix) enables users to adopt proper test protocols in case of low-expression porcine IFN-α genes. This is accounted for by the much higher sensitivity of the test protocol with EvaGreen(®) supermix. Interestingly, IFN-β showed the highest frequency of constitutive expression, in agreement with its definition of 'immediate early' gene in both humans and mice. Results indicate that the outlined procedure can detect both constitutively expressed and virus-induced IFN-α/β genes, as well as the impact of environmental, non-infectious stressors on the previous profile of constitutive expression.

Abstract
INTRODUCTION Morvan chorea is an antibody-mediated limbic encephalopathy characterized by severe insomnia, mental confusion, hallucinations, enacted dreams, hyperhidrosis, and neuromyotonia. CASE DESCRIPTION In a 78 years old man presenting with progressive insomnia apathy and depression, a video-polysomnogram documented enacted dreams mimicking daily life activity (oneiric stupor). This finding led us to perform a search for serum antibodies to voltage-gated K+ channels, which was positive. A diagnosis of Morvan chorea was done. The patient underwent plasma exchange with complete resolution of the clinical picture. CONCLUSIONS Oneiric stupor may represent a useful precocious diagnostic marker in Morvan chorea.

Abstract
Clinical chemistry parameters were investigated in piglets weaned at 22 and 28 days. The effects of an oral, low-dose interferon (IFN)-alpha treatment at weaning were evaluated as well. The trial was carried out on 59 piglets from the same farm, allocated to three groups: the first and the second groups were weaned at 28 and 22 days of age, respectively; the third group was weaned at 22 days and orally treated at weaning with IFN-alpha at a low dose (1 IU human lymphoblastoid IFN-alpha /kg body weight in drinking water) for 10 consecutive days. The results of the field trial confirmed that weaning is one of the main stressing events for pigs at intensive farms. In particular, these findings are based on a dramatic increase in serum haptoglobin levels after weaning in the three groups under study. Results also indicated that early weaning at 22 days implies higher environmental adaptation. In such animals, an oral, low-dose IFN-alpha treatment gave rise to a peculiar, negative, acute-phase response (reduced levels of serum albumin) and to significantly lower alpha-globulin concentrations in sera. Taken together, IFN-alpha was shown to modulate inflammatory responses to early weaning stress.

Abstract
Ocular involvement is a prevalent feature in mitochondrial diseases. Leber's hereditary optic neuropathy (LHON) and dominant optic atrophy (DOA) are both non-syndromic optic neuropathies with a mitochondrial etiology. LHON is associated with point mutations in the mitochondrial DNA (mtDNA), which affect subunit genes of complex I. The majority of DOA patients harbor mutations in the nuclear-encoded protein OPA1, which is targeted to mitochondria and participates to cristae organization and mitochondrial network dynamics. In both disorders the retinal ganglion cells (RGCs) are specific cellular targets of the degenerative process. We here review the clinical features and the genetic bases, and delineate the possible common pathomechanism for both these disorders.

Abstract
Feline immunodeficiency virus sustains an AIDS-like syndrome in cats, which is considered a relevant model for human AIDS. Under precise enrolment requirements, 30 naturally infected cats showing overt disease were included in a trial of low-dose, oral human interferon-alpha treatment. Twenty-four of them received 10 IU/Kg of human interferon-alpha and 6 placebo only on a daily basis under veterinary supervision. The low-dose human interferon-alpha treatment significantly prolonged the survival of virus-infected cats (p<0.01) and brought to a rapid improvement of disease conditions in the infected hosts. Amelioration of clinical conditions was neither correlated with plasma viremia, nor with proviral load in leukocytes. A good survival of CD4+ T cells and a slow increase of CD8+ T cells were also observed in human interferon-alpha-treated cats. Interestingly, the improvement of the total leukocyte counts showed a much stronger correlation with the recovery from serious opportunistic infections. As shown in other models of low-dose interferon-alpha treatment, there was a rapid regression of overt immunopathological conditions in virus-infected cats. This hints at a major role of interferon-alpha in the control circuits of inflammatory cytokines, which was probably the very foundation of the improved clinical score and survival despite the unabated persistence of virus and virus-infected cells.

Abstract
Two approaches for simultaneous identification of both Foot-and-mouth disease virus (FMDV) and Swine vesicular disease virus (SVDV) are described: (1) a single-step reverse transcription-PCR with three primers and (2) a PCR-ELISA assay with two universal primers for genome amplification and two virus-specific probes for identification. These methods are based on the use of 3D gene universal PCR primers, the structure of which was optimized and refined due to the close relationship between the two viruses belonging to different genera of the Picornaviridae family. In procedure (1), a three-primer PCR containing one universal antisense primer and two virus-specific primers was shown to differentiate between FMDV and SVDV in one reaction, due to the different length of the amplified DNA fragments (600 and 340 base pairs, respectively). In procedure (2), the two viruses were identified by PCR-ELISA, i.e. PCR for the 3D gene followed by two parallel hybridizations with FMDV and SVDV-specific probes in microplate wells and ELISA detection. The application of universal primers could halve the number of PCR experiments in both cases, as compared to the usual virus-specific PCR procedures. Also, we investigated the 3D gene structure of several SVDV strains isolated at different times. No essential changes were detected in the regions coding for conserved motifs of the RNA-dependent RNA polymerase recognized by our universal primers. The multi-primer PCR was successfully tested on 38 FMDV and 15 SVDV strains, and the PCR-ELISA on 32 FMDV and 16 SVDV strains including clinical material from disease cases.

Abstract
Mycobacterium bovis isolation on bacteriological media from suspected cases of bovine tuberculosis (TB) demands laborious and time-consuming procedures. Even polymerase chain reaction (PCR) and radiometric analyses are secondary procedures and not alternatives to bacteriological procedures. Therefore, there is a need to develop new techniques aimed at rapid M. bovis detection in diagnostic samples. The human macrophage cell line THP-1 was thus investigated in experiments of M. bovis propagation and isolation from reference lymph node suspensions. THP-1 cells were shown to support a high-titered propagation within 48h of minute amounts of both M. bovis BCG and fully pathogenic M. bovis strain 503. A semi-nested PCR for TB-complex-specific insertion sequence IS6110 revealed M. bovis infection in THP-1 cells. The same was true of a flow cytometry (FC) assay for expression of M. bovis chaperonin 10 in infected cells. The reduced time for isolation and identification of M. bovis (48-72h) and the consistency of the test results make the use of macrophage cell cultures attractive and cost-effective for veterinary laboratories involved in TB surveillance.

Abstract
Because of the frequent exposure of cattle to mycobacteria of the avium/intracellulare group, an investigation was carried out into the possible repercussions thereof on the diagnosis of bovine tuberculosis. Three calves from a bovine tuberculosis-free herd, scored avian reactors in the gamma-interferon assay for bovine tuberculosis, were sedated and inoculated endotracheally with a virulent Mycobacterium bovis strain. Then, three other avian reactors were housed with the above donor calves. Mycobacterium bovis was isolated from the nasal swabs of the three endotracheally infected, donor calves. On these samples, TB complex-specific polymerase chain reaction (PCR) tests for IS6110 were also positive, albeit with a different time kinetics. The three contact-infected calves showed clear immunological signs of infection; however, their nasal swabs were always PCR-negative and only Mycobacterium avium was isolated. In the endotracheally infected donor calves there was a rise of the gamma-interferon responses to avian and bovine purified protein derivative (PPD) tuberculins, which reached the same stable plateau levels over the whole experiment. The above effect was also observed in the contact-infected calves, even though the response to avian PPD tuberculin always remained at a higher level. By using conventional bovine and avian PPD tuberculins, the comparative intradermal test was generally positive in endotracheally infected, as opposed to contact-infected calves; a positive intradermal test for M. bovis was obtained in two contact-infected calves by different bovine PPD tuberculins based on M. bovis bacillus Calmette-Guerin (BCG) secreted or somatic antigens. It was concluded that M. bovis infection may be concealed for some time in cattle sensitized by mycobacteria of the avium/intracellulare group and that different diagnostic procedures should be adopted for such animals.

Abstract
Immunostimulants represent a modern and promising tool in aquaculture, enhancing the resistance of cultured fish to disease and stress. This study investigated the effect of a combination of dietary glucans, alpha-tocopherol and ascorbic acid on the innate immune response of cultured sea bass (Dicentrarchus labrax). After 5 weeks of adaptation on a commercial diet containing 100 p.p.m. ascorbic acid and 200 p.p.m. alpha-tocopherol, sea bass were switched to a diet supplemented with 2% beta-1.3/beta-1.6 glucans and ascorbic acid and alpha-tocopherol at 500 p.p.m. The supplemented diet was given at 2% of body weight per day over a 2-week period, every 3 months. Plasma lysozyme concentration, content and distribution of major plasma proteins and complement activity were measured prior to feeding the supplemented diet and after 40 weeks. Alternative pathways of complement activation and lysozyme activity were both significantly enhanced in fish fed on glucans and elevated doses of vitamins. No significant differences were observed in protein content or in albumin/globulin ratio. Compared to lysozyme activity, which showed marked individual variation, complement-mediated haemolytic activity has been shown to be a more reliable indicator of sea bass immunocompetence. Further studies are in progress to clarify the effect of each dietary component on the innate immune response and disease resistance.

Abstract
We investigated the specificity of the gamma-interferon test for bovine tuberculosis (TB) in 1,557 cattle in 30 paratuberculosis-free and officially certified TB-free dairy herds, located in three provinces of the Lombardy Region in Northern Italy. The TB-free status of the herds under examination was further confirmed by the tuberculin skin test, by an antibody assay and by post mortem examination of animals culled from the herds during the study period. The specificity of the gamma-interferon tests after a single test and a double sampling scheme were 88.8% and 95.4%, respectively. After a single test, 11.7% of dubious reactors were also detected, while most cattle (47.4%) were shown to be avian reactors, probably due to contamination from infected birds and/or forage. There was strong evidence that the specificity of the test could be related to the animals' interaction with environmental mycobacteria and/or ageing. To reduce the percentage of nonspecific bovine reactors under alleged TB-free conditions, test procedures might involve the use of more specific antigens and/or different reaction thresholds.

Abstract
Chaperonin 10 of M. tuberculosis conferred partial or total protection against generalized foot-and-mouth disease (FMD) in guinea-pigs challenged with O1 Lausanne FMD virus. Chaperonin 10-immunized animals mounted an antibody response to the protein, one epitope of which was found in the C-terminal half. A similar recognition pattern was observed in FMD-convalescent guinea-pigs, swine and cattle. Anti-chaperonin 10 sera showed antiviral activity against FMDV-infected BHK-21 cells. There was strong evidence that early after infection these cells actively secrete their histones and that antisera to the chaperonin recognize them. The same antisera reacted with purified histones in immunoblotting. Most important, exogenously added histones abrogated the anti-viral activity of the antiserum and an anti-histone monoclonal antibody had strong antiviral activity against FMDV-infected BHK-21 cells. These results are consistent with previous reports on displacement of histones from the nuclear compartment and immune recognition of self-histones after viral infections. On the whole, they indicate that M. tuberculosis chaperonin 10 enables the immune system to react against early abnormalities of virus-infected cells; this is accomplished by antibody cross-reacting with histones released during virus infection.

Abstract
Wide heterogeneity was shown among different batches of bovine protein purified derivative (PPD) tuberculin, as regards protein content and antigenic profile. These features were also investigated in pilot preparations of Mycobacterium bovis secreted antigens and PPD tuberculins. Under controlled conditions, widely different compositions were revealed as a function of the M. bovis strain and also of the time in culture, due to the transient expression of seemingly important clusters of antigens. Furthermore, these parameters could dramatically affect the efficacy of the above preparations in in vitro assays of cell-mediated immunity on M. bovis-infected cattle. The field exposure to mycobacteria of the avium/intracellular group could also influence the readout of such assays, results being in agreement with a bystander suppression model of the response to M. bovis antigens. Due to the above, practical suggestions are put forward to improve the composition of bovine PPD tuberculins and the relevant control procedures.

Abstract
A case of a 64-year-old man with eccrine carcinoma arising from hand skin is reported. At the time of diagnosis he showed bilateral pneumonic metastases. Although the patient underwent two systemic chemotherapy lines, he showed further progressive disease of the lung. For this reason a third chemotherapy line was started through thoracic stop-flow infusion. In this way, a five month stable disease had been achieved. The patient died 7 months later for progressive disease. The rarity of this disease, the uncertain treatment, the feasibility and efficacy of thoracic stop-flow infusion are underlined and further studies are suggested.

Abstract
Clinical immunological and haematological parameters, along with clinical conditions and growth rate, were studied in 413 male Holstein Frisian calves introduced into a large centre for genetic selection in different seasons of the year. Abnormalities were revealed by the laboratory tests in the great majority of calves after transportation stress, a general tendency to the restoration of physiological values being evident thereafter. Laboratory parameters were highly correlated with disease conditions: with three exceptions only, animals showed altered laboratory parameters some days before the occurrence of clinical symptoms. Eighteen per cent of animals showed altered laboratory parameters with no obvious clinical signs of disease; yet they experienced a reduced weight gain. Results suggest that clinical immunological and haematological parameters could be the foundation of a new, large-scale, robust approach to the control of welfare in cattle, which should be integrated preferably by a further range of records and measures.

Abstract
Intra-arterial hepatic chemotherapy (LAHC) results in significantly higher response rate than the best systemic treatment of liver metastases from colorectal cancer, but no survival advantage has to date shown because of extra-hepatic progression. From June 1991 to December 1994, twenty patients with hepatic metastases from colorectal cancer were enrolled. All patients underwent laparotomy for the placement of an intra-arterial catheter into the gastroduodenal artery connected with a subcutaneous port. All patients underwent cholecystectomy and biopsy of liver lesion to confirm metastatic disease. Locoregional schedule was: 5-fluorouracil (5FU) 500 mg/sqm, epirubicin (EPI) 13 mg/sqm, mitomycin-C (MMC) 7 mg/sqm, in bolus every 3 weeks. Systemic therapy consisted of leucovorin 500 mg/sqm, over 2 hours and 5FU 600 mg/sqm in bolus every week. Treatment was planned over a six month period. The complete response (CR) plus partial response (PR) rate was 50% of the entire group. The median survival was 18 months and 1- and 2- and 3-year survival rates were 71%, 38% and 20% respectively. Prior to chemotherapy, LDH value and % of liver involvement were the only significant prognostic parameters. Toxicity was absent or mild and no patient stopped treatment because of side effects. Combined systemic and IAHC is an effective treatment for liver metastases from colorectal cancer, with a mild or moderate toxicity. However, more trials are needed, to improve the control of the extrahepatic disease.

Abstract
Conventionally, tumor size, axillary lymph nodes status, histologic type and grading, proliferative activity, steroid receptors have been used to predict the natural history of breast cancer. In node-negative patients with breast cancer it is most important to identify biological markers that can predict the risk of systemic relapse. These features have been used to allow selection of the best treatment. In this paper we describe the prognostic significance of new tumoral markers in breast cancer patients without axillary involvement. We analyze the prognostic role and the correlation with response to treatment of these parameters: ploidy, oncogenes, p53, epidermal growth factor receptor and cathepsin D.

Abstract
BHK-21 c13 monolayer and suspension cells were investigated with regard to some phenotypic features which could bear on the quality of foot-and-mouth disease virus (FMDV) antigen produced in them. Despite good viability, suspension cells differed from monolayer cells in fundamental features of susceptibility to FMDV. Most important, FMD virus particles grown in suspension cells at high passage levels were shown to be largely degraded following inactivation with an aziridine compound. Suspension cells were characterised by a downregulation in the surface expression of both alpha 5 and alpha V integrin chains. According to the results of binding assays, both integrins could act as FMDV receptors on BHK-21 c13 cells. Reduced surface expression of integrins was correlated with disappearance of actin stress fibres, which would play a role in regular encapsidation of viral RNA and hence in stability of virus particles. With regard to FMD vaccine production, practical suggestions are put forward to evaluate the quality of BHK-21 c13 cells and FMDV Ag, which must prove stable during downstream processing.

Abstract
In this study, the Cochlear Implant Programme of the ENT Department of Ospedale Civile di Venezia, is presented. Between 1989 and 1994, after a rigorous selection process, 36 patients were selected to be implanted with a cochlear prostheses: 28 with the multichannel Nucleus 22 device, 5 with the Clarion implant and 3 with the single channel Med-E1 BTE device. The distribution of the patients according to age, etiology, duration of auditory deprivation, age at onset of deafness, is presented. The different speech-coding strategies of the Nucleus system (Wearable Speech Processing, Multipeak speech processing and Spectral Maximum Sound processor) and the stimulation mode (common ground, bipolar, bipolar + 1) as well as the Clarion speech coding strategy (Continuous Interleaved Samples and Compressed Analog) are briefly discussed. The rehabilitation programme, the specific speech recognition assessment test batteries-Consonant Confusion Test, Vocal Confusion Test, Speech Tracking, MAC battery-as they are employed in our department, are presented. As we have analyzed our results, certain factors appear as predicting a favourable outcome: - age of onset of deafness; postlingual patients, who have developed communication skills compare favourably to the perilingual group. - durations of auditory deprivation, as it is related to surviving cells in the cochlea: the shorter the period of deafness, the better the results. - length of electrode insertion, as it is determined by ossification of the cochlea. - high dynamic range of the MAP. - percent of activated electrodes: a number of 10 active electrodes or less predicts a poor outcome. - for simplification reasons, a new variable is introduced-Auditory Deprivation Index- and its positive correlation to the performance presented. - the time period of experience with the device, length and quality of rehabilitation and family support have to be mentioned.

Abstract
Intraarterial chemotherapy is studied as an alternative procedure for the neoadjuvant treatment of locally advanced and recurrent breast cancer. Our study was aimed at investigating the feasibility, the toxicity and the local response rate of an intraarterial chemotherapy regimen including 5-fluorouracil, epirubicin and mitomycin. These drugs were administered angiographically into the subclavian and internal mammary arteries ipsilateral to the lesion. We treated 20 women with a median age of 58 years (range: 42-74 years); 12 patients had locally advanced breast cancer with a median tumor size of 12 cm (range: 6-20 cm) and 8 patients exhibited cutaneous, thoracic or axillary recurrences, with a median lesion size of 6 cm (range: 3-12 cm). In all, we administered 54 cycles of chemotherapy drugs (mean: 2.7 cycles a patient). Most patients were submitted to selective catheterization of the internal mammary artery (44/54 cycles); all the drugs were injected into the subclavian artery only when catheterization of this vessel was unfeasible. No angiography-related toxicity was observed. No systemic, particularly hematological, toxicity was observed. Four patients exhibited skin erythema in the feeding region of the internal mammary artery, 2 hemialopecia, 1 cutaneous steatonecrosis and 1 transient hemiplegia. We obtained 1 complete remission and 11 partial responses, with 60% overall response rate (12/20 patients). All the patients with locally advanced breast cancer had an objective response and the mean interval between the start of therapy and radical mastectomy was only 49 days. In conclusion, intraarterial chemotherapy for locally advanced or recurrent breast cancer is a feasible and well-tolerated tool which needs further studies, particularly to assess its efficacy.

Abstract
BACKGROUND The optimal management of primary gastric lymphomas has yet to be defined. In the past surgery was advocated as the optimal first step for patients with PGL. Recently, an increasing number of studies suggest that chemotherapy is as effective as surgery. METHODS Fourteen patients with PGL were treated with chemotherapy alone. For patients with low-grade lymphoma, chemotherapy consisted of mitoxantrone 5 mg/sqm on days 1 to 3. Treatment courses were administered every 3 weeks up to a maximum of 6 cycles. Patients with high-grade lymphoma received chemotherapy according to the CHOP schedule every 4 weeks up to a maximum of 6 cycles. Two patients with high-grade lymphoma were treated as low-grade lymphoma patients (one because of age and poor performance status, the other because she refused chemotherapy that would cause hair loss). Two patients with low-grade lymphomas who did not respond to mitoxantrone were crossed over to CHOP. RESULTS All patients were evaluable for toxicity, 13 for response to therapy and survival. Toxicity was mild or moderate. Neither perforation nor hemorrhage was observed. Eleven patients achieved a complete remission (85%), 1 a partial remission (7.5%) and 1 underwent disease progression (7.5%). At a median follow-up of 12 months (range 4-44 months) all complete responders are alive and disease free. CONCLUSIONS Although the number of evaluable patients is too small to draw any final conclusions, chemotherapy seems to be as effective as surgery in PGL, and stomach preservation improves the quality of life of the patients.

Abstract
A population of mononuclear cytotoxic cells from peripheral blood leucocytes of cattle showed no usual markers of B and T lymphocytes. However, it could be allocated to a previously unreported gamma delta T cell compartment. This assumption was suggested by: 1. The surface expression of CD3; 2. PCR amplification of the C delta TcR gene from cDNA; and 3. The detection of peripheral blood precursors expressing the workshop cluster (WC) 1 marker of bovine gamma delta T cells. These cells are recognized by murine monoclonal antibodies (mAbs) 5D4, 1E7, 6F9 and 8D7, raised in the authors' laboratory. The above mAbs also identify distinct groups of cells in thymus, spleen, lymph nodes and about 1% of uncultured PBL. The most diffuse infiltration of such cells was shown in the small intestine, as both intraepithelial and lamina propria lymphocytes. Mucosal homing activity was confirmed by immunoperoxidase staining on tongue and pharynx sections of healthy cattle.
