Abstract
Paslahepevirus balayani genotypes 3 and 4 (HEV-3 and 4) have zoonotic potential and can be transmitted to humans and animals through the consumption of contaminated raw or undercooked meat. Although it has been demonstrated that dogs are susceptible to the infection and produce specific antibodies, the epidemiological role of this species is not yet well defined. This study aimed to evaluate the circulation of HEV at the serological and molecular level in the dog population of the Campania region, southern Italy. A total of 231 dogs were sampled, divided according to several variables (sex, age, origin, lifestyle, location, size, and breed), and tested for the presence of HEV antibodies using a commercial multi-species ELISA. A total of 197 blood samples and 170 stool samples were tested with two specific PCRs in order to detect viral RNA. A total of 19 out samples of 231 were seropositive, obtaining an exposure (8.2%) similar to that observed in other European countries. The univariate and multivariate analysis revealed a wide exposure to stray dogs and animals from the province of Salerno. All samples tested with molecular methods were negative. Defining the role of domestic carnivores continues to be a "one health" challenge, although it appears that they do not eliminate the virus and therefore do not pose a danger to humans. In the absence of other evidence, it is advisable to continue to carry out surveillance also for domestic animals, which, due to ethological characteristics or their position in the food chain, could be predisposed to being exposed to HEV.

Abstract
BACKGROUND AND OBJECTIVE Colorectal cancer is one of the most common malignancies among the general population. Artificial Intelligence methodologies based on serum parameters are in continuous development to obtain less expensive tools for highly sensitive diagnoses. This study proposes a predictive system based on serum biomarkers and ensemble learning to predict colorectal cancer presence and the related TNM stage in patients. METHODS We have selected 17 significant plasmatic proteins, i.e., Carcinoembryonic Antigen, CA 19-9, CA 125, CA 50, CA 72-4, Tissue Polypeptide Antigen, C-Reactive Protein, Ceruloplasmin, Haptoglobin, Transferrin, Ferritin, α-1-Antitrypsin, α-2-Macroglobulin, α-1 Acid Glycoprotein, Complement C4, Complement C3, and Retinol Binding Protein, regarding 345 patients (248 affected by the neoplastic disease). The proposed system consists of two predictors, i.e., binary and staging; the former predicts the presence/absence of cancer, while the latter identifies the related TNM stage (I, II, III, or IV). The experiments were conducted by deploying and comparing Random Forest, XGBoost, Support Vector Machine, and Multilayer Perceptron with feature selection based on Gini Importance and with dimensionality reduction via PCA. RESULTS The results show that the system composed of XGBoost as binary and staging predictor reaches 91.30% accuracy, 90% sensitivity, and 93.33% specificity for the absence/presence outcome, while 66.66% accuracy for the staging response. With the expansion of the training set in favor of positive patients and majority voting, the system composed of the combination of Support Vector Machine, XGBoost, and Multilayer Perceptron as the binary predictor reaches 98.03% accuracy, 100% sensitivity, and 92.30% specificity, while the combination of Random Forest, XGBoost, and Multilayer Perceptron as staging predictor achieves 60% accuracy. The final system reaches, in terms of accuracy, 98.03%, and 66.66% for the binary and staging predictors, respectively. It was also found that the biomarkers which contribute most to the binary decision are Ceruloplasmin and α-2-Macroglobulin, while the least significant dimensions are CA 50 and α-1-Antitrypsin; instead, Carcinoembryonic Antigen and α-1 Acid Glycoprotein are the most significant to the staging decision. CONCLUSIONS The present study proves the effectiveness of deploying serum biomarkers as feature dimensions for early colorectal cancer diagnosis and of using majority voting for noise reduction in the prediction.

Abstract
In 2015 bladder cancer was the fourth most frequent malignancy and the eighth cause of death for cancer. At diagnosis, about 30% of bladder cancer (BC) patients present a muscle-invasive bladder cancer (MIBC) and 5% a metastatic bladder carcinoma (MBC). For fit MBC patients, combination chemotherapy (CC) is the standard of care for first-line treatment. CC includes both the treatment with methotrexate, vinblastine, doxorubicin, and cisplatin (MVAC) either the classical or the dose-dense MVAC regimen, and the doublet therapy with cisplatin and gemcitabine (CG). Median progression free survival (PFS) was 7 months and median overall survival (OS) was 15 months. The present review provides an update on the management of MBC, with focus on target therapies, immune checkpoint inhibition, looking for prognostic and predictive factors.

Abstract
Paratuberculosis is a chronic enteric disease affecting virtually all ruminants, but only anecdotal information is currently available about the occurrence of this disease in water buffaloes (Bubalus bubalis). We carried out a survey study aimed at determining the prevalence of paratuberculosis in 2 provinces in the region of Campania, Italy, where about half of all Italian buffaloes are reared. From May 2017 to December 2018, we collected 201,175 individual serum samples from 995 buffalo herds. The sera were collected from animals over 24 mo old and were tested using a commercial ELISA test. The herd-level apparent prevalence result was 54.7%, and the animal-level apparent prevalence was 1.8%. The herd-level true prevalence was estimated using a Bayesian approach, demonstrating a high herd-level prevalence of paratuberculosis in water buffaloes from the Campania area. These findings suggest that the urgent adoption of paratuberculosis herd-control programs for water buffaloes in this area would be beneficial.

Abstract
Penile cancer (PC) is a typical tumor of non-industrialized countries. The incidence is 20-30 times higher in Africa and South America, considering the elevated prevalence of sexually transmitted diseases. Histologically, PC includes squamous cell carcinoma (SCPC), the most frequent, and nonsquamous carcinoma (NSCPC). Early diagnosis is the goal, whereas later diagnosis relates to poor functional outcomes and worse prognosis. The 5-year survival rate is 85% for patients with histologically regional negative lymph nodes, compared to 29%-40% for those with histologically regional positive lymph nodes. To date no new drugs are approved, and there are few new data about molecular mechanisms underlying tumorigenesis. The SCPC remains a rare tumor and the current therapeutic algorithm is based principally on retrospective analysis and less on prospective trials. In this review article, biomarkers of prognosis and efficacy of current treatments are summarized with a focus on those that have the potential to affect treatment decision-making in SCPC.

Abstract
OBJECTIVE Testicular cancer is a relatively rare neoplasia, with an incidence of about 1,5% among male malignancies, usually in the third and fourth decade of life. Although several histological variants are known, with some histotypes affecting older patients (e.g., spermatocytic seminoma), there is a clear predominance (90-95%) of germ cell tumors among young adults patients1. Testicular Germ Cell Tumor (TGCT), undoubtedly the seminoma histological variant more than non-seminoma one, is definitely a highly curable disease, with a distinctive sensitivity to cisplatin-based therapy (and for seminomas to radiotherapy) and an outstanding cure rate of nearly 80% even for patients with advanced disease. So far, clinical and pathohistological features supported our efforts to choose the best treatment option for patients suffering from this malignancy, but we don't clearly enough know molecular and pathological features underlying different clinical behaviors, mostly in early-stage disease: by improving this knowledge, we should better "shape" therapeutic or surveillance programs for each patient, also in order to avoid unnecessary, if not harmful, treatments.

Abstract
OBJECTIVE In this review, we focused our attention on Quality of Life (QoL) of testicular cancer survivors (TCSs), in general and in the most relevant areas. Several key findings have been highlighted in our review. MATERIALS AND METHODS PubMed, MEDLINE and PsycINFO databases were consulted to find published studies, from 1980 to May 2017, that met our inclusion criteria. RESULTS The majority of studies investigated older adult TCSs, while few studies on adolescent and young adult patients were available. Many studies indicate that health-related QoL (HRQoL) is similar among the TCSs and the general population. Even if QoL deteriorates so clear at the time of diagnosis and throughout treatment, afterward returns to normal levels, as defined by the matched controls. However, there are numerous chronic conditions consequent to diagnosis and treatment of testicular cancer that plague survivors and affect QoL, like Raynaud-like phenomena, peripheral neuropathy, fatigue, anxiety, sexual, fertility and body image problems. Even if these problems can have no effects on the measures of global QoL, they have an impact on the quality of life. Differences between TCSs with and without a partner bring to different outcomes in the adjustments to cancer. CONCLUSIONS It is necessary to identify TCSs with higher risks of poorer QoL outcomes, to focus interventions on the areas with the greatest impairments. Further researches should consider the effects of testicular cancer on the impaired areas, collecting more data to better identify survivor's needs and consequent interventions, with a special focus on adolescent and young adult TCSs. Other works are requested on therapies, preventive and ameliorative, to reduce chronic side effects of testicular cancer treatment.

Abstract
OBJECTIVE The aim of our report was to review the literature concerning the toxicity of radiation therapy in patients treated for high-risk prostate cancer, and to evaluate the differences in toxicity between conventional fractionation and hypofractionated treatments, in view of different techniques used in high-risk prostate cancer patients. MATERIALS AND METHODS PubMed database has been explored for studies concerning acute and late urinary/gastrointestinal toxicity in high-risk prostate cancer patients treated with radiotherapy. Prospective studies, concerning potential relationship between acute/late genitourinary (GU)/gastrointestinal (GI) toxicity and prostate radiotherapy in patients with high-risk prostate cancer, were included in the final analysis. Data collected from single arm, phase II non-randomized and randomized studies have been evaluated to perform odds ratio for toxicity risk. Furthermore, meta-analysis randomized prospective trials were considered suitable because they had recruited high-risk prostate cancer patients who didn't undergo surgery, with available data on ≥ G2 toxicity frequency. RESULTS The initial search provided 606 results, but only 35 manuscripts met all eligibility requirements and were included in this report. In order to perform odds ratio we observed a decrease in late gastrointestinal toxicity for patients treated with hypofractionated schemes compared to CV treated ones. Among patients who underwent conventional treatment, SIB seemed to decrease acute genitourinary side effects; SIB-Hypo treated patients suffered less toxicity than patients treated with hypofractionated- sequential boost schemes. Hypo-SIB schemes would seem less toxic in terms of acute gastrointestinal and late genitourinary side effects than CV-SIB. Therefore, our focus shifted to 6 clinical trials evaluating genitourinary and gastrointestinal toxicity in patients who had been randomized to receive conventional fractionation or hypofractionated treatment, in both cases with IMRT technology. Our meta-analysis of these randomized trials involving patients with high-risk prostate cancer showed a statistically significant increase in late genitourinary toxicity for hypo-treated patients; no difference was observed in acute genitourinary/gastrointestinal toxicity, and in late gastrointestinal toxicity. CONCLUSIONS Our analysis doesn't want to establish a definitive truth; very few trials assessed only high risk-class patients. Our purpose is to stimulate further randomized prospective trials focusing both on the effectiveness and toxicity profile (toxicity/effectiveness ratio), taking into account the use of different technologies and doses.

Abstract
In 2008, after the crisis of buffalo dairy fields in Campania, Italy, an assessment of the contamination of polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDD/Fs) and dioxin-like polychlorinated biphenyls (dl-PCBs) was also necessary for other animal species bred in the region. The contents of PCDDs, polychlorinated dibenzofurans (PCDFs), and dl-PCBs were determined by high-resolution gas chromatography/mass spectrometry (HR-GC/MS) (according to USEPA method 1613) in 69 sheep and goat milk samples from 63 farms. In eleven samples from six sheep farms, the PCDD/Fs levels exceeded the maximum limit of 3.0 pg g(-1) fat established by the European Commission, in particular the concentrations ranged between 3.89 and 12.90 pg g(-1) fat. Statistical treatment of the results for the congener profiles of the non-compliant and compliant samples has been used to identify the sources of contamination.

Abstract
Two hundred and twenty Escherichia coli isolates from 314 Mediterranean water buffalo calves less than 4 weeks old affected by severe diarrhoea with a lethal outcome were characterized for the presence of the virulence factors LT, ST, Stx1, Stx2, haemolysins, intimin, CNF1, CNF2, CDT-I, CDT-II, CDT-III, CDT-IV, and F17-related fimbriae (F17a, F17b, F17c, F17d). The prevalence of ETEC, STEC and NTEC were 1.8%, 6.8% and 20.9%, respectively. The ETEC isolates were all LT-positive and ST-negative. The STEC isolates were all Stx and intimin-positive, with Stx1 (80%) more frequent than Stx2 (27%). The NTEC isolates were all CNF and Hly-positive, with CNF2 (83%) more frequent than CNF1 (22%). Susceptibility assays to 11 antimicrobials displayed high rates of resistance (>30%) to antimicrobials tested. These data show that the most prevalent strains in diarrhoeic water buffalo calves were NTEC, mostly CNF2 and HlyA-positive, with strong associations CNF2/CDT-III and CNF2/F17c.

Abstract
It is known that Caprine Herpesvirus 1 (CpHV-1) causes apoptosis in mitogen-stimulated as well as not stimulated caprine peripheral blood mononuclear cells (PBMC). Initial experiments in Madin Darby bovine kidney (MDBK) cells revealed that CpHV-1 infection induced apoptotic features like chromatin condensation and DNA laddering. Thus, to characterize in more detail this apoptotic process, activation of caspase-8, -9 and -3 in MDBK cells CpHV-1 infected was investigated and demonstrated. In addition, CpHV-1 infection resulted in disruption of mitochondrial membrane potential, cytochrome c release and alterations in the pro- and anti-apoptotic proteins of Bcl-2 family. Proteolytic cleavage of poly(ADP-ribose) polymerases (PARP), confirming the activation of downstream caspases, was also observed. Our data indicated that a "cross-talk" between the death-receptor (extrinsic) pathway and the mitochondrial (intrinsic) pathway occurred in CpHV-1-induced apoptosis in vitro.

Abstract
Papillomas and fibropapillomas may occur in the skin and in different organs in animals. Ten different genotypes of bovine papillomavirus (BPV) have been identified. BPV-1 through BPV-10 are all strictly species-specific, but BPV-1/2 may also infect other species such as equids, inducing fibroblastic tumors. BPV-1 and BPV-2 are associated with fibropapillomas in cattle; these tumors are formed by excessive proliferation of virus-infected dermal fibroblasts and epidermal keratinocytes. Nine water buffalo (Bubalus bubalis) were examined for the presence of multiple cutaneous and perivulvar tumors. Cutaneous and perivulvar fibropapillomatosis were confirmed histologically. Negative-stain transmission electron microscopic examination revealed papillomavirus-like particles in the fibropapillomas, and papillomaviral DNA was also detected by the polymerase chain reaction. The amplified long control region (LCR) DNA sequence was identical to that of BPV-1. The BPV-1 E5 oncoprotein was strongly expressed in the tumor cells thus confirming a causal role of the virus. This article represents the first report of cutaneous, perivulvar, and vulvar fibropapilloma associated with BPV-1 infection in the water buffalo and describes another example of cross-species infection by BPV-1.

Abstract
Cytotoxic T lymphocytes (CTLs) are an essential component of the immune defense against many virus infections. CTLs recognize viral peptides in the context of the major histocompatibility complex (MHC) class I molecules on the surface of infected cells. Many viruses have evolved mechanisms to interfere with MHC class I expression as a means of evading the host immune response. In the present research we have studied the effect of in vitro Feline Herpesvirus 1 (FeHV-1) infection on MHC class I expression. The results of this study demonstrate that FeHV-1 down regulates surface expression of MHC class I molecules on infected cells, presumably to evade cytotoxic T-cell recognition and, perhaps, attenuate induction of immunity. Sensitivity to UV irradiation and insensitivity to a viral DNA synthesis inhibitor, like phosphonacetic acid, revealed that immediate early or early viral gene(s) are responsible. Use of the protein translation inhibitor cycloheximide confirmed that an early gene is primarily responsible.

Abstract
The fluorescence polarization assay (FPA) was evaluated for the serological diagnosis of brucellosis in water buffalo (Bubalus bubalis) in southern Italy. This assay uses O-polysaccharide prepared from Brucella abortus lipopolysaccharide conjugated with fluorescein isothiocyanate as a tracer. It has many methodological advantages over older, more established tests and can be performed in a fraction of the time. Sera from 890 buffalos from the Campania Region - 526 positive sera and 364 negative sera according to the complement fixation test (CFT) - were evaluated in this study. All samples were tested with the Rose Bengal test (RBT), CFT, and FPA in parallel and in blind fashion. Sensitivities (Sn) were 84.5% and 92.6%, and specificities (Sp) were 93.1% and 91.2% for RBT and FPA, respectively, relative to CFT. Finally, receiver operating characteristic (ROC) analysis suggested a cut-off value of 117 millipolarization (mP) units. On the whole, these results suggested that FPA might replace RBT in the diagnosis of buffalo brucellosis for its better performance relative to CFT, its adjustable cut-off useful in different epidemiological situations, its reliability, ease of performance, and for its potential application in field and high-throughput laboratories.

Abstract
Dioxin-2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) is a common environmental toxin of current interest. In the last years, higher levels of TCDD than those permitted in UE [European Commission. 2002. European Commission Recommendation 2002/201/CE. Official Gazette, L 67/69] were detected in milk samples from cow, water buffalo, goat, and sheep raised on some areas of Campania Region (South Italy). Dioxin often causes immunosuppression and might render the animal liable to viral infections. In addition, viral infections are able to alter the pattern of dioxin distribution in different organs of the exposed animals. Bovine Herpesvirus type-1 (BHV-1) is a widespread pathogen, which causes infectious rhinotracheitis and infectious pustular vulvovaginitis in cattle. Herein, we have studied the effects of TCDD and BHV-1 infection, in Madin-Darby Bovine Kidney (MDBK) cells, alone as well as in association, so as cellular proliferation, apoptosis, and virus replication. We have observed an increase in cell viability of confluent monolayers at low TCDD concentrations. TCDD treated cells demonstrated increased viability compared to controls as evaluated by MTT test. TCDD exposure increased cell proliferation but induced no changes on apoptosis. Cells exposed to TCDD along with BHV-1 showed a dose-dependent increase in cytopathy, represented by ample syncytia formation with the elimination of the cellular sheets and increased viral titer. These results suggest that TCDD increases viral replication in MDBK cells while BHV-1 further decreases viability of TCDD exposed cells. Since very low concentrations (0.01 pg/ml) are sufficient to augment BHV-1 titer, TCDD may contribute to reactivate BHV-1 from latency, leading to recurrent disease and increase virus transmission.

Abstract
Bacterial pathogens are a potential cause when a mare fails to conceive to a fertile stallion on a well-managed breeding farm on one or more cycles in the same season. Furthermore, emerging bacterial resistance to commonly used (topical) antibiotics has been demonstrated. In this study, a total of 586 uterine swabs from mares with fertility problems were evaluated and the bacterial isolates were identified and measured for resistance to 10 antibiotics most commonly used during bacterial equine infection. Forty-nine percent of the examined mares were positive at bacteriological investigations. Amongst 347 successful isolations, 31.7% were Streptococcus group C and 18.4% Escherichia (E.) coli, both considered frequently associated with fertility problems. Determination of the antibiotic susceptibility pattern of Streptococcus group C (110 organisms) revealed that only the amoxicillin/clavulanic acid was highly active with 82.7% of the isolates being inhibited. For E. coli, a major number of drugs displayed a high potency.

Abstract
Following semen collection, the nonspecific bacterial count is usually kept low by addition of antibiotics to the extender. Ordinary protocols for semen processing in preparation for IVF are characterized by a washing procedure, followed by spermatozoa selection by either swim-up or Percoll gradient. In this study, commercially available bovine semen to be used for IVF was found to be heavily contaminated with Escherichia coli and Leclercia adecarboxilata despite the addition of tylosin (5 mg/100 mL), gentamicin (25 mg/100 mL), spectomycin (30 mg/100 mL), and lincomycin (15 mg/100 mL) to the extender. Bacterial concentrations varied among straws examined (n = 7), ranging from 10 � 4 UFC mL-1 to 10 � 8 UFC mL-1. Noncontaminated semen from the same valuable bull, although derived from a different semen collection, was known to be used with great efficiency for IVF in a different laboratory at a very low concentration (i.e. 350 000 sperm mL-1). Therefore, to rescue the fertilizing capacity of such contaminated semen, an improved treatment was applied and compared with the ordinary semen treatment. From the previous use of semen from the same bull, a concentration of 2 million sperm/mL-1 and 20 �g mL-1 of heparin was chosen for IVF. During ordinary treatment, the semen was washed using 6 mL of fertilization medium into a 15-mL tube and subjected to centrifugation at 800 rpm for 5 min. After removal of the supernatant, the resulting pellet was layered under 1 mL of the same medium and left for 45 min in an incubator for swim-up. The supernatant was moved into a new 15-mL tube for additional centrifugation. The newly formed pellet was then resuspended for the final count and co-incubation with oocytes. With such a procedure, the bacterial contamination was found for 3 consecutive replicates in culture droplets starting at Days 3 to 4 post-IVF. In the course of 5 additional replications, the semen treatment was improved by doubling the volume for initial washing to 12 mL of fertilization medium. The resuspended pellet following the first centrifugation was equally partitioned into 6 round-bottomed tubes and left for 60 to 80 min in an incubator for swim-up. The supernatant was then moved into a new 15-mL tube for additional centrifugation and a final count. The IVF medium was supplemented with 100 IU mL-1 of penicillin G in both treatments. Following the ordinary and improved semen treatment, a large number of sperm cells were found agglutinated head-to-head. A subsequent embryo culture was performed for both treatments in SOF containing 0.025 mg mL-1 of kanamycin sulfate. When using sperm and heparin concentrations at 2 million and 20 �g mL-1, respectively, under the improved semen treatment, cleavage was 84.8%. The rates of blastocyst production at Day 7 from used cumulus-oocyte complexes and from cleavage were 29.5 and 35.9%, respectively. In conclusion, the improved washing procedure rescued valuable but heavily contaminated semen for use in IVF procedures.

Abstract
A seroprevalence survey of Neospora caninum and bovine herpesvirus 1 (BHV-1) was conducted in cattle pasturing in an area of the southern Italian Apennines to investigate the coinfection of these two pathogens. Blood samples were collected from 948 pastured cattle raised on 81 farms. Sera were tested for antibodies to N. caninum and to BHV-1 using an ELISA assay and a neutralization test, respectively. Out of the 81 farms sampled, 63 (77.8%) were positive for N. caninum and 80 (98.8%) for BHV-1. Coinfection was found in 62 (76.5%) farms. Out of the 948 bovine sera samples, 303 (32.0%) had antibodies to N. caninum and 735 (77.5%) to BHV-1. The copresence of antibodies to N. caninum and BHV-1 was found in 256 (27.0%) cattle. The logistic regression results indicated that seropositivity for BHV-1 was a risk factor for N. caninum seropositivity and seropositivity for N. caninum was a risk factor for BHV-1 seropositivity.

Abstract
To investigate on the hypothetical presence of an antiapoptotic gene, we utilized the CODEHOP (COnsensus-DEgenerate Hybrid Oligonucleotide Primers) strategy amplifying unknown sequences from a background of genomic (bovine herpesvirus type-1) BHV-1 DNA. An alignment of carboxyl-terminal domains belonging to three proteins encoded by gamma34.5, MyD116 and GADD34 genes, was carried out to design degenerate PCR primers in highly conserved regions. This allowed the amplification of a 110 bp fragment. This fragment was subjected to automatic sequencing and DNA sequence analysis revealed that its position resided between the nt 14363 and the nt 14438 in bovine herpesvirus type-1 (BHV-1) Cooper strain sharing an identity of 86% (UL14). Transient transfections showed that UL14 protein is efficient in protecting MDBK and K562 cells from sorbitol induced apoptosis. The protein's anti-apoptotic function may derive from its heat shock protein-like properties.

Abstract
The proliferative capacity of mammalian cells is regulated by telomerase, an enzyme uniquely specialised for telomeric DNA synthesis. The critical role of telomerase activation in tumor progression and maintenance has been well established in studies of cancer and of oncogenic transformation in cell culture. Experimental data suggest that telomerase activation has an important role in normal somatic cells, and that failure to activate sufficient telomerase also promotes disease. Evidence regarding the role of telomerase in the pathogenesis of several viruses including human immunodeficiency virus has led to an increased interest in the role of telomerase activity in other virus infections. In this research we evaluated the telomerase modulating activity of Bovine herpesvirus 1 (BHV-1) in MDBK cells. MDBK cells were infected at different multiplicity of infection with BHV-1 Cooper strain and telomerase activity at different times post-infection was measured by the TRAP assay. Our data indicate that BHV-1 significantly up-regulates telomerase activity at 3 and 6h post-infection decreasing after the 24h post-infection. Our data, showed that the effect was mediated by an immediate-early or early viral gene, and use of the protein translation inhibitor cycloheximide confirmed that an immediate early gene is primarily responsible.

Abstract
Programmed cell death (PCD), or apoptosis, is initiated in response to various stimuli, including virus infection. A number of studies have shown that deregulation of apoptosis is an important feature of virus-induced immunosuppression for various viral diseases. In the present study, CapHV-1 was found to cause apoptosis in mitogen-stimulated as well as nonstimulated caprine peripheral blood mononuclear cells (PBMC). Apoptotic index, as quantified by fluorescent dyes, revealed a significant increase in the percentage of apoptotic cells at 24 and 48 h postinfection as compared to their respective noninfected controls. Apoptosis specific internucleosomal laddering in DNA from CapHV-1 infected PBMC was seen in agarose gel electrophoresis. No DNA fragmentation was observed in control noninfected PBMC. Virus-induced apoptosis was reduced by Z-VAD-FMK, an aspecific caspase inhibitor, by AC-DEVD-CHO (caspase-3-specific) and AC-VEID-CHO (caspase-6-specific) treatment. PCD in CapHV-1 infected peripheral blood mononuclear cells occurs at the G0/G1 phase of the cell cycle. However, penetration of virus particles and infection was not required for PCD, as UV-inactivated CapHV-1 induced apoptosis of mitogen-stimulated bovine peripheral blood mononuclear cells in vitro.

Abstract
Bovine herpesvirus type 4 (BHV-4) belongs to the gamma-2-herpesviruses of the Gammaherpesvirinae subfamily. BHV-4 has a worldwide distribution and has been isolated in a variety of clinical diseases as well as from healthy cattle. In this report we demonstrate that BHV-4 induces apoptosis in MDBK cells. In the early phases of apoptosis, cells show an increase in the intracellular level of reactive oxygen species, which is indicative of oxidative stress. This precedes DNA fragmentation, a hallmark typical of apoptosis. Cells were protected from apoptosis only by certain antioxidants (butylated hydroxyanisole and ebselen), whereas N-acetylcysteine turned out to be ineffective. Antioxidants that protected cells from apoptosis prevented oxidative stress but failed to block virus growth. These observations suggest that oxidative stress may be a crucial event in the sequence leading to apoptotic cell death but apoptosis is not required for the multiplication of BHV-4.

Abstract
In order to determine the ability of bovine herpesvirus type 1 (BHV-1) to suppress apoptosis, we examined the effects of BHV-1 infection on sorbitol-induced apoptosis on Madin-Darby bovine kidney (MDBK) cells. BHV-1 suppresses sorbitol-induced apoptosis in a manner similar to that of herpes simplex virus type 1 (HSV-1), indicating that BHV-1 has one or more anti-apoptotic genes. To elucidate the molecular mechanisms of apoptosis, expression of some genes encoding apoptosis-inhibiting and -promoting factors were analyzed on BHV-1 infected cells during the process of sorbitol-induced apoptosis. Our results revealed that the expression of bcl-2 and bcl-x(L) decreased after 5 and 3 h p.i., respectively; while bax and procaspase-3 expression increased with respect to control as a function of p.i. times and at 7 h p.i. they were not observed. We further show that the expression of p53 gene was also enhanced, suggesting that this apoptotic mechanism is p53 dependent. From these results, we propose that BHV-1 has one or more genes encoding apoptosis-inhibiting factors which interfere with the involvement of bcl-2 gene family members and apoptotic pathway, depending upon caspase-3, triggered by sorbitol.

Abstract
Failure of chemotherapy with anthracyclines as a result of drug resistance and toxicity is a major problem in the clinical management of neoplasia. The aim of the present study was to evaluate the activity of medroxyprogesterone acetate (MPA) as a chemosensitiser on anthracycline cytotoxicity. The study investigated whether such an effect could be related to an increase in lipid peroxidation, nitric oxide production, membrane fluidity and intracellular anthracycline concentration. The results showed that anthracyclines decreased nitric oxide production but increased membrane viscosity (polarisation constant) and lipid hydroperoxide formation in canine mammary tumour cells. Moreover, it was found that both drug-induced cytotoxicity and membrane viscosity increased in the presence of MPA. Conversely, lipid hydroperoxides decreased in MPA-supplemented cells. Medroxyprogesterone acetate did not show any effect on nitric oxide production. The two anthracyclines used (doxorubicin and idarubicin) showed differential intranuclear accumulation in canine mammary tumour cells, and MPA significantly modified intracellular concentration of anthracyclines.
