Abstract
In small and laboratory animals epididymal spermatozoa can be collected only by the mincing technique however, blood and cell debris contamination may adversely affect the quality of the samples. This study aimed at performing the retrograde flushing technique, for the first time, in the tomcat. In the first experiment attempts to insert a blunted needle into tomcats' ductus deferentes were made and the cannulation time and the success rate were recorded. In the second experiment, insertion of the needle into the ductus was carried out under a stereomicroscope for one testis, while the other was submitted to mincing for sperm recovery and the samples obtained from paired testes were compared. In the first study, only twenty-eight percent of the cannulation attempts were successful whereas in the second experiment, 91% of the deferentes were successfully cannulated: 80% of the ducts were cannulated in less than three minutes. The stereomicroscope-aided retrograde flushing samples showed significantly higher sperm viability, motility and velocities, as compared to those resulted from mincing. The domestic cat serves as a model for more than 36 species of wild felids; the developed stereomicroscope-aided retrograde flushing technique has the potential to become the gold standard method for harvesting spermatozoa of endangered species that have a small ductus deferens.

Abstract
Alphaherpesviruses cause genital lesions and reproductive failure in both humans and animals. Their control is mainly based on prevention using hygienic prophylactic measures due to the absence of vaccines and limitations of antiviral drug therapy. Ozone is an oxidating gas showing a strong microbicidal activity on bacteria, fungi, viruses, and protozoa. The present study assessed the in vitro virucidal and antiviral activity of ozone against caprine herpesvirus type 1 (CpHV-1). The virucidal activity of a gaseous mixture containing O3 at 20 and 50 μg/mL was assessed against the virus at different contact times (30 s, 60 s, 90 s, 120 s, 180 s, and 300 s). Antiviral activity of a gaseous mixture containing O3 at 20 and 50 μg/mL was evaluated against the virus after 30 s and 60 s. Ozone displayed significant virucidal activity when used at all the tested concentrations whilst significant antiviral activity was observed using ozone at 50 μg/mL. The gaseous mixture, tested in the present study, showed virucidal and antiviral activity against CpHV-1 in a dose- and time contact-dependent fashion. Ozone therapy could be evaluated in vivo for the treatment of CpHV-1-induced genital lesions in goats using topical applications.

Abstract
Ozone is an oxidating gas showing a strong microbicidal activity on bacteria, fungi, viruses and protozoa. The aim of this study was to test the in vitro bacteriocidal action of an Ozone/Oxygen gas mixture on bacteria isolated from the cervico-vaginal mucus of cows affected by acute metritis. A pilot study was initially carried out on reference strains (Escherichia coli ATCC 25922, Staphylococcus aureus ATCC 25923 and Mycoplasma bovigenitalium ATCC 19852) that were tested with three different treatments: a control positive baseline group (B-group) was incubated without gas treatment, a control positive oxygen group (O2-group) was treated with pure oxygen 100%, and the treated group (T-group) was exposed to a gaseous constant flow of an Ozone/Oxygen mixture, at 50, 35, 20 μg Ozone/ml and for 5, 3 and 1 min for every different Ozone concentration. In both positive control groups, the number of colony forming units (CFU) per ml was higher than 300 CFU/ml (E. coli and S. aureus) and higher than 30 CFU/ml for M. bovigenitalium, after incubation. The T-groups showed a minimal bacterial growth equal to or lower than 1 CFU/ml per plate. Based on the results of the pilot study, a second phase was performed on bacteria isolated from the cervico-vaginal mucus (Klebsiella pneumoniae, Enterobacter agglomerans, E. coli, Proteus mirabilis and M. bovigenitalium) using the lower concentration of 20 μg/ml of Ozone for the minimum exposure time of 1 min. The E. coli and S. aureus reference strains and the clinical isolates (K. pneumoniae, E. agglomerans, E. coli, P. mirabilis) were incubated at 37 °C for 48 h and the colonies were manually counted at 24 h and 48 h following inoculation. The cultures of M. bovigenitalium (both ATCC and clinical isolate) were incubated in a jar with modified atmosphere conditions with 5% CO2 at 37 °C for 4-7 days and colony counting was performed. The second phase showed a low number of CFUs (equal to or less than 7 CFU/ml) for the clinical isolates K. pneumoniae, E. agglomerans, E. coli and P. mirabilis, and, of note, for M. bovigenitalium, both ATCC and clinical isolate, the growth was completely inhibited. Ozone was demonstrated to have a bacteriocidal activity. This study encourages further research of in vivo application of low doses of gaseous Ozone for the treatment of metritis in cows by using minimal exposure times.

Abstract
Antibiotics are commonly used to treat bacterial infections. For many years, antibiotics have been used at sub-therapeutic doses to promote animal growth and misused as prophylactics and metaphylactic on farms. The widespread and improper use of antibiotics has resulted in a serious problem, defined as antibiotic resistance by the World Health Organisation, which is a major public health threat in the 21st century. Bacteria have evolved sophisticated mechanistic strategies to avoid being killed by antibiotics. These strategies can be classified as intrinsic resistance (referring to the inherent structural or functional characteristics of a bacterial species) or acquired resistance (referring to mutations in chromosomal genes or the acquisition of external genetic determinants of resistance). In farm animals, the use of antibiotics warrants serious consideration, as their residues leach into the environment through effluents and come into contact with humans through food. Several factors have contributed to the emergence of antibiotic-resistant bacteria. This review provides an update on antibiotic resistance mechanisms, while focusing on the effects of this threat on veterinary medicine, and highlighting causal factors in clinical practice. Finally, it makes an excursus on alternative therapies, such as the use of bacteriophages, bacteriocins, antimicrobial photodynamic therapy, phytochemicals, and ozone therapy, which should be used to combat antibiotic-resistant infections. Some of these therapies, such as ozone therapy, are aimed at preventing the persistence of antibiotics in animal tissues and their contact with the final consumer of food of animal origin.

Abstract
Simple Summary Cryptorchidism is the failure of one or both the testes to descend in the scrotum. In pigs, the incidence of cryptorchidism varies from 4% to 12%, and the most frequent localisation of retained testes is the abdominal region. In other species, transabdominal ultrasound is the most reliable diagnostic tool to localize the retained testis. This study aimed to evaluate the value of ultrasound in correctly identifying the location of retained testes, to improve the cryptorchidectomy in pigs. The ultrasound examination reduced the duration of anaesthesia, surgery, and postoperative pain. Indeed, the technique used is safe, effective, and rapid. To locate the testis, it should recognise the echo structure of the testicle and the mediastinum is well always recognisable for its hyperechogenicity. The routine use of the ultrasound examination is considered a useful alternative before the cryptorchidectomy in the pig because it allows the exact location of the retained testicle, ensuring reduced manipulation of the viscera. Abstract This study aimed to describe a technique to locate retained testes in pigs by means of ultrasound examination and thereafter proceed with cryptorchidectomy. Fifty-two monolateral cryptorchid pigs were enrolled. After anaesthesia, 42 pigs (Group U) underwent ultrasound examination before cryptorchidectomy, and 10 pigs (Group C) were used as control group without ultrasonography. The total duration of anaesthesia, ultrasound examination, and surgery was evaluated. In 10 pigs of Group U and 10 pigs of Group C, the heart rate (HR), respiratory rate (RR), and body temperature (T) were monitored to assess intraoperative pain response. An operator used the Piglet Grimace Scale (PGS) to assess postoperative pain. In Group U, the total time required for anaesthesia and surgery was less than Group C. No intra- or postoperative complications were reported in both groups. For HR, RR, and T, no statistically significant differences were observed. During the postoperative pain assessment, the highest pain scores were recorded at T6 (6 h after surgery). Ultrasound examination was found to be a valid technique for locating the retained testis in the abdomen in cryptorchid pigs and to reduce the duration of the surgery.

Abstract
Objectives The aim of this study was to compare the analgesic efficacy of topical irrigation versus injection of lidocaine on the ovarian pedicle to provide analgesia in bitches ovariectomy. In the current study were monitored: increased blood pressure, heart rate and respiratory rate to identify an acute intraoperative nociceptive response. These parameters were registered at six times during the surgical procedure: grasping of the ovary (time 1), dissection of the mesosalpinx (time 2), tightening of the first loop ligature (time 3), tightening of the second loop ligature (time 4), transection of the ovarian pedicle (time 5) and release of the ovary (time 6). Material and Methods Forty healthy bitches were randomly assigned in two groups (n = 20) to receive topical irrigation (splash block) of 2% lidocaine (C group) on both ovarian pedicle (2 mg/kg each), or an equal volume of lidocaine was injected at the same sites (R group). Results The results of the present study suggest that splash block may provide intraoperative analgesic effects equivalent to injection in the ovarian pedicle in dogs that have undergone ovariectomy. The lidocaine improved surgical analgesia during canine ovariectomy in both groups, and this action is not affected by the inoculation technique. Clinical significance Pain management in veterinary patients is a crucial component of appropriate patient care. Therefore, the need for achieving safer anaesthesia for surgical intervention is gaining much attention. Ovariectomy is a common surgical procedure in bitches with medium level of pain. This study concluded that considering its relative simplicity, low cost, and safety, both techniques could be used in daily clinical practice.

Abstract
Ozone (O3) is a triatomic form of oxygen. As O3 rapidly dissociates into water and releases a reactive form of oxygen that may oxidize cells, the gas mixture of O3/O2 is used in medicine. ATP is widely available for cellular activity. O3 can be administered via the systemic and local routes. Although O3 is known as one of the most powerful oxidants, it also promotes antioxidant enzymes. Additionally, it stimulates some of the cells of the immune system and inactivates pathogens, including bacteria, fungi, yeasts, protozoa, and viruses. Owing to these activities, O3 is used to improve several diseases, both in human and in veterinary medicine. Considering the wide scope of O3 application, the aim of this review was to reiterate the mechanisms of action of O3 and its utilization in different mammalian species (bovine, ovine-caprine, equine, canine, porcine).

Abstract
BACKGROUND 18F-FDG PET/CT predicts cardiovascular disease. To analyze the predictive value of cardiovascular events from inflammation and arterial calcification in patients who underwent an 18F-FDG PET/CT for lung cancer. METHODS A retrospective study of 274 patients with primary lung neoplasia. We determined: (i) TBR (target-to-background ratio), and (ii) the calcium score, at eight common arterial segments. We took as arteriosclerosis, a TBR ≥1.6 and ≥15 Calcium Score sum. We registered cardiovascular risk factors, comorbidities, histology, stage, treatment, status at the last clinical review, cause of death and cardiovascular event during the follow-up. RESULTS The territory presenting the greatest uptake of 18F-FDG, was the thoracic aorta with an average of 1.77 (± 0.27 TBR) in the aortic arch, while the greatest degree of calcification was obtained in the abdominal aorta (52% with a Calcium Score ≥ 3). 24% of the patients presented a sum Calcium Score ≥15, and 17% a TBR ≥1.6. Patients with high TBR, (17%), had not a higher frequency of cardiovascular comorbidities beforehand, nor did they in the follow-up. However, those with a sum Calcium Score ≥15 (24%), were older, had more cardiovascular risk factors and ischemic events during follow-up. The calcium score, but not the TBR, predicted the emergence of a cardiovascular event (HR 4.9 IC95% 2.1-9.1, P < 0.05). CONCLUSION In our cohort, a high Calcium Score was an independent predictor for developing cardiovascular events.

Abstract
From January 2011 to December 2015, 70 consecutive patients underwent either laparoscopic surgery (LS) or robotic surgery (RS) total mesorectal excision (TME) for malignancy. Data were prospectically recorded in a dedicated local database including ASA score, age, operative time, conversion rate, re-operation rate, early complications, length of stay, and pathological results. We enrolled 70 consecutive patients, 35 treated with LS (18 M, 17 F), 35 treated with RS (23 M, 12 F). Median total operative time was 225 min in LS group (IQR 194-255) and 252.5 min for RS group (IQR 214-300). Median first flatus time was 2 days for LS group (IQR 1-3) and 1 day for RS group (IQR 1-2). Stool discharge time (median) was 4 days for LS group (IQR 2-5) and 2 days for RS group (IQR 1-3). Length of stay (median) was 8 days in LS group (IQR 7-10) and 7 days in RS group (IQR 5-8). It was not found any statistically significant difference between the two groups when we analyzed the number nodes harvested the postoperative complications. The 30 day mortality was 0% in both two groups. The conversion rate for LS group was 23% (8/35 pts) and that for RS group was 0% (0/35). The RS may overcome technical limitations of LS. In our experience, it is a feasible and safe technique, it achieves better clinical outcomes due to the lower conversion rate compared to LS, although with higher costs.

Abstract
Robotic-assisted resections prove beneficial in overcoming potential limitation of laparoscopy, but clear evidences on patient's benefits are still lacking. We report our experience on 100 consecutive patients who underwent right colectomy with either robotic or laparoscopic approaches. Data were prospectively collected on a dedicated database (ASA score, age, operative time, conversion rate, re-operation rate, early complications, length of stay, and pathological results). Median total operative time was 160 min in LS group (IQR = 140-180) and 204 min for RS group (IQR = 180-230). Median time to first flatus was 2.5 days for LS group (IQR = 2 - 3) and 2 days for RS group (IQR = 1-2). Length of stay (median) was 8 days in LS group (IQR = 6-10) and 5 days in RS group (IQR = 5-7). No statistically significant difference was found between the 2 groups when the number of harvested nodes, the anastomotic leakage and the postoperative bleeding were analyzed. The 30-day mortality was 0% in LS and RS groups. Conversion rate for LS group was 14% (7/50 pts) and for RS group was 0% (0/50). Minimally invasive surgery is a feasible and safe technique. The RS may overcome some technical limitations of laparoscopic surgery and it achieves the same oncological results compared to LS but with higher costs. The lower conversion rate allows to expect better clinical outcomes and lower complication rate.

Abstract
AIM Organ transplantation is the most effective treatment for several degenerative end-stage diseases. While the mainstream immunosuppression can achieve satisfactory results, the therapy has either side effects and flaws. The golden target to reach should be a stable tolerance with the transplanted organ accepted without a long term drug administration. Recent studies demonstrated a tolerogenic effect of spleen cells. Aim of this study is to evaluate a model of combined spleen and whole organ transplantation in a significant preclinical setting in swine. METHODS Twenty-five outbred Landrace/Large-White swine underwent combined spleen/kidney transplantation (SKTx). The experiments were stratified into 3 groups per randomization. Group 1 (N=7) received kidney transplantation (KTx) alone with no immunosuppressive treatment. Group 2 (N=9) had a combined KTx and whole graft spleen Tx. Group 3 (N=9) had KTx and spleen cells (DST), injected through the portal vein. Renal lab tests were collected to evaluate the onset of rejection. Survivals were evaluated as well. The end-point of the study was at onset of kidney failure or at the limit of 60 postoperative day (POD) in non-rejecting animals. Tissue samples were collected to evaluate grade and severity of rejection. RESULTS Controls died from kidney failure within 10(th) POD. Group 2 and 3, had a delayed renal graft rejection and an overall prolonged graft survival. Whole graft and spleen cells injection share this effect, while spleen administration through the portal route proved a superior effect, which is significant compared to controls (Kaplan Meier survival analysis P<0.05). CONCLUSIONS These results, from a non immunosuppressed setting, suggest that spleen plays a key role as an immunomodulatory organ.

Abstract
AIM Costimulatory blockade and donor specific transfusion (DST) can catalyze tolerance of transplanted organs through a multistep adaptation between the recipient and donor immune systems. Such an in vivo process may prolong graft survival. Aim of this study was to evaluate the outcome of aortic transplantation under CTLA4Ig and DST in a mismatched model in rats. METHODS Orthotopic aortic transplantation was performed in recipients Lewis from Wistar-Furth rats. The animals were stratified into 3 groups, according to the postoperative treatment. Group 1 had aortic transplantation only (controls, n=6), while group 2 (n=7) had a load of donor splenocytes (DST). Group 3 was treated with DST and CTLA4Ig. All the animals were sacrificed at the 60th postoperative day and the aortic specimens were prepared for histology. Intimal cells, muscular cells and lymphocyte cell infiltration were evaluated by serial counts. RESULTS In Group 1 there was a severe chronic rejection, while group 2 showed a slower onset of chronic rejection with less inflammatory infiltrate than group 1 (P<0.05). Group 3 had the best overall outcome with lower infiltration and minimal alterations compared with groups 1 and 2. CONCLUSIONS Costimulatory blockade and DST load can prevent the onset of chronic rejection in this experimental setting. Despite the wide availability of immunosuppressors, which makes transplantation a today's clinical routine, the solution to chronic rejection is still elusive. The synergistic role of splenocytes and costimulatory blockade raises interesting perspectives about the immunomodulatory role of spleen in tolerance induction.

Abstract
BACKGROUND There is limited information available regarding the relationship between clinical indicators of widespread disease in patients with lung cancer and the findings of transcutaneous ultrasonography. METHODS A retrospective survey was made of 279 consecutive patients with lung cancer. By reviewing the patients' records the clinical findings were divided into symptoms, signs, and laboratory tests indicative of metastatic disease. All patients had been examined by abdominal ultrasonography. RESULTS The patients included 19% with small cell carcinoma. The frequency of abdominal metastases by ultrasonography in those with small cell carcinoma was 40%, in the other patients it was 8%. Regardless of histological group, all the 40 patients with abdominal metastases by ultrasonography had at least one clinical category indicative of widespread disease and 38 (95%) had two or all three clinical categories positive. Fifty nine patients had no clinical indicators of metastases and none of these had abdominal metastases by ultrasonography. CONCLUSIONS The results of this study indicate that abdominal metastases are found in lung cancer patients with clinical findings indicative of widespread disease. No abdominal metastases were found in patients with a negative clinical evaluation. The results indicate that transcutaneous ultrasonography of the abdomen is not necessary in the initial staging if the clinical evaluation is unremarkable.

Abstract
A rapid, precise procedure is described for the determination of lead in food and feed products with electrothermal atomic absorption spectrophotometry. Samples were mineralized in a microwave acid digestion bomb in the presence of nitric acid and vanadium pentoxide. Lead concentrations were determined directly from digested samples. The detection limit was 0.04 ng/mL. Accuracy and precision were checked against National Institute of Standards and Technology standard reference material. The analytical method was tested with 51 food and feed crops from Mediterranean zones in Spain and found to be suitable for these products. Lead concentrations in samples ranged from not detectable to 2.695 micrograms/g (fresh weight).

Abstract
Two hundred chronic low-back pain patients entering a functional restoration program were assessed for current and lifetime psychiatric syndromes using a structured psychiatric interview to make DSM-III-R diagnoses. Results showed that, even when the somewhat controversial category of somatoform pain disorder was excluded, 77% of patients met lifetime diagnostic criteria and 59% demonstrated current symptoms for at least one psychiatric diagnosis. The most common of these were major depression, substance abuse, and anxiety disorders. In addition, 51% met criteria for at least one personality disorder. All of the prevalence rates were significantly greater than the base rate for the general population. Finally, and most importantly, of these patients with a positive lifetime history for psychiatric syndromes, 54% of those with depression, 94% of those with substance abuse, and 95% of those with anxiety disorders had experienced these syndromes before the onset of their back pain. These are the first results to indicate that certain psychiatric syndromes appear to precede chronic low-back pain (substance abuse and anxiety disorders), whereas others (specifically, major depression) develop either before or after the onset of chronic low-back pain. Such findings substantially add to our understanding of causality and predisposition in the relationship between psychiatric disorders and chronic low-back pain. They also clearly reveal that clinicians should be aware of potentially high rates of emotional distress syndromes in chronic low-back pain and enlist mental health professionals to help maximize treatment outcomes.
