Abstract
BACKGROUND The aim of this paper was to assess COVID-19 pandemic impact over the public health care services (HCS) involved in special care dentistry (SCD). METHODS Customized questionnaire was sent to 45 HCS involved in SCD. Healthcare personnel (HP) on duty, safety of HCS, time of suspension and reduction of routine dental practice in special needs patients (SNP), kind of SNP mostly penalized during pre-COVID period/T1, lockdown (phase 1/T2) and post pandemic reopening (phase 2/T3) were analyzed by statistical means (P<0.05). RESULTS 21 questionnaires were returned. A significant decrease of median number of HP during T2 was observed. Prevalence of COVID-19 infection among HP was not significantly different between T2 vs. T3. Medical surveillance of HP during T2 was significantly lower than during T3. Patients with lack of cooperation were the most disadvantaged during both phases dental procedures were significantly lower between T1 and T2 and between T1 and T3 as well. Patients with lack of cooperation and/or living in residential care homes were the most disadvantaged in relation to access to dental care during both phases. CONCLUSIONS COVID-19 pandemic determined significant restrictions in daily access to routine oral care resulting in reduction of preventive evaluations and decline of oral health in a population which is already at a higher risk of oral pathologies. Our data reveal that reduction of dental procedures, healthcare professionals and days of suspension of clinical activity were still considerable also in T3 with respect to T1 and in some cases not significantly different from T2.

Abstract
Morphological changes that may arise through a treatment course are probably one of the most significant sources of range uncertainty in proton therapy. Non-invasive in-vivo treatment monitoring is useful to increase treatment quality. The INSIDE in-beam Positron Emission Tomography (PET) scanner performs in-vivo range monitoring in proton and carbon therapy treatments at the National Center of Oncological Hadrontherapy (CNAO). It is currently in a clinical trial (ID: NCT03662373) and has acquired in-beam PET data during the treatment of various patients. In this work we analyze the in-beam PET (IB-PET) data of eight patients treated with proton therapy at CNAO. The goal of the analysis is twofold. First, we assess the level of experimental fluctuations in inter-fractional range differences (sensitivity) of the INSIDE PET system by studying patients without morphological changes. Second, we use the obtained results to see whether we can observe anomalously large range variations in patients where morphological changes have occurred. The sensitivity of the INSIDE IB-PET scanner was quantified as the standard deviation of the range difference distributions observed for six patients that did not show morphological changes. Inter-fractional range variations with respect to a reference distribution were estimated using the Most-Likely-Shift (MLS) method. To establish the efficacy of this method, we made a comparison with the Beam’s Eye View (BEV) method. For patients showing no morphological changes in the control CT the average range variation standard deviation was found to be 2.5 mm with the MLS method and 2.3 mm with the BEV method. On the other hand, for patients where some small anatomical changes occurred, we found larger standard deviation values. In these patients we evaluated where anomalous range differences were found and compared them with the CT. We found that the identified regions were mostly in agreement with the morphological changes seen in the CT scan.

Abstract
Purpose In‐beam positron emission tomography (PET) is one of the modalities that can be used for in vivo noninvasive treatment monitoring in proton therapy. Although PET monitoring has been frequently applied for this purpose, there is still no straightforward method to translate the information obtained from the PET images into easy‐to‐interpret information for clinical personnel. The purpose of this work is to propose a statistical method for analyzing in‐beam PET monitoring images that can be used to locate, quantify, and visualize regions with possible morphological changes occurring over the course of treatment. Methods We selected a patient treated for squamous cell carcinoma (SCC) with proton therapy, to perform multiple Monte Carlo (MC) simulations of the expected PET signal at the start of treatment, and to study how the PET signal may change along the treatment course due to morphological changes. We performed voxel‐wise two‐tailed statistical tests of the simulated PET images, resembling the voxel‐based morphometry (VBM) method commonly used in neuroimaging data analysis, to locate regions with significant morphological changes and to quantify the change. Results The VBM resembling method has been successfully applied to the simulated in‐beam PET images, despite the fact that such images suffer from image artifacts and limited statistics. Three dimensional probability maps were obtained, that allowed to identify interfractional morphological changes and to visualize them superimposed on the computed tomography (CT) scan. In particular, the characteristic color patterns resulting from the two‐tailed statistical tests lend themselves to trigger alarms in case of morphological changes along the course of treatment. Conclusions The statistical method presented in this work is a promising method to apply to PET monitoring data to reveal interfractional morphological changes in patients, occurring over the course of treatment. Based on simulated in‐beam PET treatment monitoring images, we showed that with our method it was possible to correctly identify the regions that changed. Moreover we could quantify the changes, and visualize them superimposed on the CT scan. The proposed method can possibly help clinical personnel in the replanning procedure in adaptive proton therapy treatments.

Abstract
Particle therapy in which deep seated tumours are treated using 12C ions (Carbon Ions RadioTherapy or CIRT) exploits the high conformity in the dose release, the high relative biological effectiveness and low oxygen enhancement ratio of such projectiles. The advantages of CIRT are driving a rapid increase in the number of centres that are trying to implement such technique. To fully profit from the ballistic precision achievable in delivering the dose to the target volume an online range verification system would be needed, but currently missing. The 12C ions beams range could only be monitored by looking at the secondary radiation emitted by the primary beam interaction with the patient tissues and no technical solution capable of the needed precision has been adopted in the clinical centres yet. The detection of charged secondary fragments, mainly protons, emitted by the patient is a promising approach, and is currently being explored in clinical trials at CNAO. Charged particles are easy to detect and can be back-tracked to the emission point with high efficiency in an almost background-free environment. These fragments are the product of projectiles fragmentation, and are hence mainly produced along the beam path inside the patient. This experimental signature can be used to monitor the beam position in the plane orthogonal to its flight direction, providing an online feedback to the beam transverse position monitor chambers used in the clinical centres. This information could be used to cross-check, validate and calibrate, whenever needed, the information provided by the ion chambers already implemented in most clinical centres as beam control detectors. In this paper we study the feasibility of such strategy in the clinical routine, analysing the data collected during the clinical trial performed at the CNAO facility on patients treated using 12C ions and monitored using the Dose Profiler (DP) detector developed within the INSIDE project. On the basis of the data collected monitoring three patients, the technique potential and limitations will be discussed.

Abstract
The high dose conformity and healthy tissue sparing achievable in Particle Therapy when using C ions calls for safety factors in treatment planning, to prevent the tumor under-dosage related to the possible occurrence of inter-fractional morphological changes during a treatment. This limitation could be overcome by a range monitor, still missing in clinical routine, capable of providing on-line feedback. The Dose Profiler (DP) is a detector developed within the INnovative Solution for In-beam Dosimetry in hadronthErapy (INSIDE) collaboration for the monitoring of carbon ion treatments at the CNAO facility (Centro Nazionale di Adroterapia Oncologica) exploiting the detection of charged secondary fragments that escape from the patient. The DP capability to detect inter-fractional changes is demonstrated by comparing the obtained fragment emission maps in different fractions of the treatments enrolled in the first ever clinical trial of such a monitoring system, performed at CNAO. The case of a CNAO patient that underwent a significant morphological change is presented in detail, focusing on the implications that can be drawn for the achievable inter-fractional monitoring DP sensitivity in real clinical conditions. The results have been cross-checked against a simulation study.

Abstract
Medication-related osteonecrosis of the jaw (MRONJ) is a major disease under study for over the last twenty years. Different classifications have been proposed and many therapies for the different stages have been applied. The evolution of treatments lead to an increasingly conservative approach. Numerous adjuvant treatments have been proposed in the last decade. All these complementary treatments have been proposed mainly to resolve or reduce the painful stress, predominantly caused by bacterial infection, simplifying the wound healing process and improving patients' compliance. Nowadays "secondary" treatments, such as autologous platelet concentrates (APCs, more specifically PRP, PRGF or PRF), hyperbaric oxygen (HBO), Auto/tetracycline fluorescence-guided bone surgery (AF-GBS/TF-GBS), medical drugs like teriparatide or the combination between pentoxifylline and tocopherol, fluorodeoxyglucose positron emission tomography (FDG-PET), laser and/or low-laser therapy and ozone therapy are more or less well documented and known considering their clinical effectiveness. The aim of the present review is the evaluation of the quantity and quality of scientific studies concerning this specific topic.

Abstract
Particle therapy (PT) can exploit heavy ions (such as He, C or O) to enhance the treatment efficacy, profiting from the increased Relative Biological Effectiveness and Oxygen Enhancement Ratio of these projectiles with respect to proton beams. To maximise the gain in tumor control probability a precise online monitoring of the dose release is needed, avoiding unnecessary large safety margins surroundings the tumor volume accounting for possible patient mispositioning or morphological changes with respect to the initial CT scan. The Dose Profiler (DP) detector, presented in this manuscript, is a scintillating fibres tracker of charged secondary particles (mainly protons) that will be operating during the treatment, allowing for an online range monitoring. Such monitoring technique is particularly promising in the context of heavy ions PT, in which the precision achievable by other techniques based on secondary photons detection is limited by the environmental background during the beam delivery. Developed and built at the SBAI department of "La Sapienza", within the INSIDE collaboration and as part of a Centro Fermi flagship project, the DP is a tracker detector specifically designed and planned for clinical applications inside a PT treatment room. The DP operation in clinical like conditions has been tested with the proton and carbon ions beams of Trento proton-therapy center and of the CNAO facility. In this contribution the detector performances are presented, in the context of the carbon ions monitoring clinical trial that is about to start at the CNAO centre.

Abstract
Summary
The present study was conducted to evaluate the prevalence of gastrointestinal and cardio-respiratory parasites in dogs in Liguria (northwest Italy) which is a region that has scarcely been studied. A total of 450 dogs (260 males and 190 females) were enrolled in the study from 2009 and 2013. All dogs lived in a rural or semi-rural environment in the provinces of Imperia (n = 352) or Savona (n = 98), Liguria. Coprological examinations showed that 197 dogs (43.8 %, CI 38.7-48.9 %) were infected by parasites. Specifically, 3.3 % of the dogs presented only cardio-respiratory species, 32.4 % only intestinal species, and 8.0 % presented a mixed infection.
The most frequent intestinal parasites were Toxocara canis (20 %), Trichuris vulpis (17.8 %), Ancylostomatidae (12 %), Coccidia (2.7 %), Aonchotheca putorii (1.8 %) and Toxascaris leonina (1.8 %). The cardio-respiratory species found were Eucoleus aerophilus (9.6 %), Eucoleus boehmi (1.6 %), Angiostrongylus vasorum (0.7 %), and Crenosoma vulpis (0.2 %). A total of 116 dogs (25.8 %) were parasitized by a single species, multiple infections were observed in 81 dogs (18.0 %) up to a six-order infection.
This preliminary study highlighted that the prevalence of intestinal parasites in investigated area is high. Cardio respiratory parasites were detected in an area that has not been investigated before. The creation of a more extensive sampling programme of the area, on a provincial basis in order to build a more detailed map of prevalences for different species of dog parasites throughout Liguria, a more extensive sampling programme of the area needs to be created - ideally for each province.

Abstract
Summary
A total of 180 foxes (Vulpes vulpes) from an area scarcely investigated of north-west Italy, were examined for intestinal helminths using sedimentation and counting technique (SCT). Faecal samples were submitted to centrifugation with 50 % zinc sulphate used as flotation solution.
No fox was found completely negative for intestinal helminths. The most frequently identified nematodes were Uncinaria stenocephala (70.0 %), Molineus legerae (27.2 %), Toxocara canis (26.7 %), Toxascaris leonina (25.6 %), Trichuris vulpis (21.1 %), Aonchotheca putorii (8.9 %), Pterygodermatites affinis (5.6 %). Genus Mesocestoides (81.7 %), family Dilepididae (29.4 %) and Taenia spp. (8.3 %) were the most prevalent cestodes. All foxes were negative for E. multilocularis and E. granulosus. In two foxes trematodes belonging to the family Plagiorchidae were found.
The study highlighted that foxes are hosts of intestinal helminths of veterinary and medical importance which may be transmitted to dogs and humans.

Abstract
Dogs can be infected by several nematodes of the Trichuridae family. Trichuridae eggs are all similar, barrel shaped with polar plugs, and misdiagnosis among different species can occur. The most common species is Trichuris vulpis, while the respiratory parasites Eucoleus boehmi (syn. Capillaria boehmi) and Eucoleus aerophilus (syn. Capillaria aerophila) are rarely observed in pets. E. boehmi is reported for the first time in this study in north-western Italy with other Trichuridae. Dog faecal samples (270) were examined by flotation. E. boehmi (2.2%), E. aerophilus (4.4%) and T. vulpis (12.2%) were found; identification was done with measurements and through observation of morphological characters already known. The specific identification of E. boehmi was confirmed using scanning electron microscopy: its egg shell shows a dense network with a fine mesh, surrounding small pits, on the contrary E. aerophilus eggs present a thick mesh with wide depressions, while T. vulpis eggs surface is smooth.

Abstract
BACKGROUND AND AIM This cluster randomized trial evaluated the efficacy of a disease and care management (D&CM) model in cardiovascular (CVD) prevention in primary care. METHODS AND RESULTS Eligible subjects had ≥ 1 among: blood pressure ≥ 140/90 mmHg; glycated hemoglobin ≥ 7%; LDL-cholesterol ≥ 160 or ≥ 100 mg/dL (primary or secondary prevention, respectively); BMI ≥ 30; current smoking. The D&CM intervention included a teamwork including nurses as care managers for the implementation of tailored care plans. Control group was allocated to usual-care. The main outcome was the proportion of subjects achieving recommended clinical targets for ≥ 1 of uncontrolled CVD risk factors at 12-month. During 2008-2009 we enrolled 920 subjects in the Abruzzo/Marche regions, Italy. Following the exclusion of L'Aquila due to 2009 earthquake, final analyses included 762 subjects. The primary outcome was achieved by 39.1% (95%CI: 34.2-44.2) and 25.2% (95%CI: 20.9-29.9) of subjects in the intervention and usual-care group, respectively (p < 0.001). The D&CM intervention significantly increased the proportion of subjects who achieved clinical targets for both diabetes and hypertension, with no differences in hypercholesterolemia, smoking status and obesity. CONCLUSIONS The D&CM intervention was effective in controlling cardiovascular risk factors, in particular hypertension and diabetes. Numbers needed to treat were small. Such intervention may deserve further consideration in clinical practice. REGISTRATION NUMBER ACTRN12611000813987.

Abstract
BACKGROUND Lactic acid bacteria (LAB) were reported to reduce some allergic manifestations in mice and humans but their impact on the aeroallergen-dependent immune mechanisms is still debated. OBJECTIVE The potential capacities of Lactobacillus plantarum NCIMB8826 to reduce the allergic response induced by Der p 1, the major house dust mite allergen of Dermatophagoides pteronyssinus, were evaluated in vivo and in vitro. Methods First, the effect of the intranasal co-administration of LAB and purified Der p 1 allergen before a sensitization protocol was evaluated. The allergen-specific antibody and cellular responses as well as airway inflammation were measured. Second, the impact of LAB on the cytokine profile of spleens cells from Der p 1-sensitized mice was assessed. Third, upon stimulation with LAB, the levels of cytokine produced by dendritic cells derived from the bone marrow (BMDCs) of wild-type, Toll-like receptor 2 (TLR2)-, TLR4- and MyD88-KO mice were compared. Results The co-application of L. plantarum and Der p 1 induced a T-helper type 1 (Th1)-biased allergen-specific IgG response, the absence of specific IgE response and favoured the production of INF-gamma upon allergen re-stimulation. Moreover, the previous LAB administration reduced the development of bronchoalveolar lavage eosinophilia usually induced by aerosol exposure. Additionally, the studied LAB strain was shown to modify in vitro the cytokine level produced by Der p 1-sensitized spleen cells mainly towards a Th1 profile. Finally, L. plantarum stimulated high IL-12 and moderate IL-10 production in mouse BMDCs notably through the TLR2-, MyD88-dependent and TLR4-independent pathway. CONCLUSION In vivo co-administration of probiotic LAB with Der p 1 might prevent the development of the mite allergic response. The probiotic L. plantarum was shown to display in vitro therapeutic potentials for the treatment of allergy and to trigger the immune system by a TLR2- and MyD88-dependent signalling pathway.

Abstract
The seroprevalence of feline immunodeficiency virus (FIV) in 203 apparently healthy domestic cats living in the district of Pisa, central Italy, was 11.3 per cent, and the prevalence of feline leukaemia virus (FeLV) was 8.4 per cent. The prevalence of FIV depended significantly on the lifestyle and age of the cats; cats living outdoors were more likely to be FIV-positive than cats living indoors, and the proportion of FIV-positive cats increased with age. In contrast, there was no significant relationship between these variables and the prevalence of FeLV. There was no significant relationship between the cats' seropositivity for FIV and FeLV. The results of a five-year field study to control FeLV infection by vaccination in a colony of 30 domestic adult cats naturally exposed to the infection suggest that the vaccination was effective in FIV-negative cats, but failed to protect FIV-positive cats against FeLV.

Abstract
Entomological investigations by means of dog- and human-baited traps were carried out in summers 2000-2002 in urban and rural areas of the Tuscan region in central Italy. The aim of the study was to define the mosquito species involved in the transmission of Dirofilaria nematodes and to assess the risk that their presence might represent for animal and human health. Nocturnal fieldwork on host-seeking activity and feeding preferences was followed by microscopic identification of the mosquito species attracted and by molecular identification of Dirofilaria parasites in mosquitoes. In total, 3,611 mosquito females belonging to 12 species, largely represented by Culex pipiens L. and Aedes caspius (Pallas), were caught. Some females of each species collected fed on the dogs, indicating their possible role as an intermediate host, but filarial DNA was found only in Cx. pipiens, Anopheles maculipennis s.l. (Meigen), and Coquillettidia richiardii (Ficalbi). In rural environments, the DNA evidence indicated the presence of infective larvae of Dirofilaria immitis, whereas in urban areas, infective larvae of Dirofilaria repens were present. The role of Cx. pipiens as a vector for heartworm disease and subcutaneous infections in natural and artificial environments was confirmed, whereas Ae. caspius seemed refractory to the infection. The different role of the collected species is discussed. The vector competence of An. maculipennis and Cq. richiardii needs further investigation, because the importance of these species poorly represented, and the role of species such as Aedes albopictus (Skuse), characterized by a dominant diurnal activity pattern, has to be evaluated.

Abstract
Myialges anchora Trouessart, 1906 and M. lophortyx (Furman & Tarshis, 1953) gravid females, surrounded by clusters of eggs, were found strongly inserted into the cuticle of head, thorax, abdomen, femurs and wings of Pseudolynchia canariensis (Macquart, 1840), a hippoboscid fly parasite of the pigeon. This lousefly results obligatory host for ovigerous females of Myialges and for the development of their eggs, and phoretic host because the dispersal of hatching larvae to new hosts may then occur with dispersal of fly carriers. Together with the Myiolges species, not ovigerous females of Ornithocheyletia hallae Smiley, 1970 and Columbicola columbae (Linnaeus, 1758) were found on the pigeon fly.

Abstract
The present research analyses the reliability of coprological tests, both quantitative and qualitative, as indicators of the parasite burden of hosts, using data from wild boars (Sus scrofa) living in Livorno Mountain Park (Tuscany, Central Italy). In the case of intestinal strongyles, which turned out to be the dominant helminths of wild boars, the qualitative coprological test appears as a bad predictor of the real parasite situation of the herds, due to the high number of false negative results (34 animals out of 68). On the other hand, the positive predictive value of the test is high (90%). The quantitative test is significantly correlated with the individual parasite burden of wild boars.

Abstract
BACKGROUND Various studies have shown that immunization with naked DNA encoding allergens induces T helper 1(Th1)-biased non-allergic responses. OBJECTIVE To evaluate the polarization of the immune responses induced by vaccinations with plasmid DNA encoding the major mite allergen precursor ProDer p 1. METHODS A DNA vaccine was constructed on the basis of a synthetic cDNA encoding ProDer p 1 with optimized codon usage. The immunogenicity of ProDer p 1 DNA in CBA/J mice was compared with that of purified natural Der p 1 or recombinant ProDer p 1 adjuvanted with alum. Vaccinated mice were subsequently exposed to aerosolized house dust mite extracts to provoke airway inflammation. The presence of inflammatory cells was examined in bronchoalveolar lavage (BAL) fluids and allergen-specific T cell reactivity was measured. RESULTS Naive mice immunized with ProDer p 1 DNA developed Th1 immune responses characterized by high titres of specific IgG2a antibodies, low titres of specific IgG1 and, remarkably, the absence of anti-ProDer p 1 IgE. No specific responses were observed in animals vaccinated with the blank DNA vector. By contrast, natural Der p 1 or recombinant ProDer p 1 adsorbed to alum induced pronounced Th2 allergic responses with strong specific IgG1 and IgE titres. Spleen cells from DNA ProDer p 1-vaccinated mice secreted high levels of IFN-gamma and low production of IL-5. Conversely, both adjuvanted allergens stimulated typical Th2-type cytokine profile characterized by high and low levels of IL-5 and IFN-gamma, respectively. Whereas BAL eosinophilia was clearly observed in Der p 1-immunized animals, ProDer p 1 DNA as well as ProDer p 1 vaccinations prevented airway eosinophil infiltrations. CONCLUSIONS These results suggest that vaccination with DNA encoding ProDer p 1 effectively fails to induce the allergen-induced IgE synthesis and airway cell infiltration. Plasmid DNA encoding ProDer p 1 may provide a novel approach for the treatment of house dust mite allergy.

Abstract
Since 1995 the population of wild ungulates increased significantly in the "Parco provinciale dei Monti Livornesi" (Livorno, Tuscany, Central Italy). We studied the intestinal macroparasites of two hosts, the wild boar (Sus scrofa) and the mouflon (Ovis gmelini musimon). In the case of wild boars we found a dominant parasite species, Globocephalus urosubulatus. For this parasite the frequency distribution of the number of parasites per host agrees with a negative binomial distribution. There is not a significant correlation between the age of the animals and the parasitosis. Furthermore the mean parasite burden of male and female wild boars does not differ significantly. In the case of mouflons we found a dominant parasite species Nematodirus filicollis with Trichuris ovis as codominant species.

Abstract
BACKGROUND The major house dust mite Der p 1 allergen is associated with allergic disease. Heterologous over-expression of biologically active Der p 1 was previously attempted but with limited success. OBJECTIVE The aim of this study was to establish an efficient system for the production of recombinant Der p 1. METHODS The proform of Der p 1 was expressed in Pichia pastoris as a fusion with the alpha mating factor signal sequence. The recombinant product was purified from culture medium and compared to Der p 1 isolated from mite culture, in terms of enzymatic activity as well as IgE binding capacity. RESULTS ProDer p 1 was efficiently secreted into culture medium as a hyperglycosylated protein of 40-60 kDa. Postpurification dialysis in acidic buffer was required for the autocatalytic processing of Der p 1. During this treatment, the prosequence was efficiently removed to give highly glycosylated recombinant mature Der p 1. Competition ELISA experiments as well as cysteine proteinase activity assays indicated that recombinant processed Der p 1 was similar to natural Der p 1 isolated from mite cultures in terms of IgE binding and enzymatic activities. However, the histamine releasing activity of recombinant Der p 1 was slightly weaker than that of natural Der p 1. CONCLUSION This efficient system for recombinant Der p 1 expression leads the way for the design of new diagnostics for house dust mite allergy, epitope mapping, allergen engineering, structural and immunological studies and new immunotherapeutic treatments.

Abstract
BACKGROUND The major house dust mite allergen Der p 1 is associated with allergic diseases such as asthma. Production of recombinant Der p 1 was previously attempted, but with limited success. The present study describes the expression of recombinant (rec) ProDer p 1, a recombinant precursor form of Der p 1, in CHO cells. METHODS As optimization of the codon usage may allow successful overexpression of protein in mammalian cells, a synthetic gene encoding ProDer p 1 was designed on the basis of the codon usage frequently found in highly expressed human genes. Gene synthesis was accomplished from a set of 14 mutually priming overlapping oligonucleotides and after two runs of polymerase chain reaction. RESULTS COS cells transiently transfected with the synthetic ProDer p 1 gene produced up to 5--10 times as much ProDer p 1 compared with the expression level obtained after transfection with the authentic gene. To stably express the recombinant allergen, CHO-K1 cells were transfected with the ProDer p 1 synthetic gene, and one amplified recombinant clone produced up to 30 mg of recProDer p 1 per liter in the culture medium before purification. recProDer p 1 was secreted as an enzymatically inactive single-chain molecule presenting three glycosylated immunoreactive forms of 41, 38 and 36 kD. When examined with respect to direct binding, recProDer p 1 and natural Der p 1 displayed very similar IgE reactivities. However, IgE inhibition and histamine release assays showed a much higher reactivity to natural Der p 1 compared to recProDer p 1. CONCLUSIONS These data indicated that codon optimization represents an attractive strategy for high-level production of allergen in mammalian cells.

Abstract
We have amplified by PCR the sequences of the 5 S ribosomal spacer of Setaria labiatopapillosa and Foleyella furcata. After sequencing, these sequences have been compared with those of Dirofilaria immitis and Dirofilaria repens. Two major goals have been achieved: (i) the establishment of a multiplex PCR-based diagnostic assay, applicable to identify the four species in vertebrate and invertebrate hosts; (ii) the identification, in S. labiatopapillosa and F. furcata, of a canonical spliced leader 1 (SL1) sequence, so confirming that only D. repens, of the filarial parasites so far studied, shows a peculiar SL1 sequence. The PCR assay here developed and the analysis of the 5 S ribosomal spacer, can further improve both epidemiological and molecular analysis of these filarial species.

Abstract
During the period January 1993-June 1994, a parasitological survey was carried out on 19 badgers (Meles meles) road killed in Northern Mugello (Florence). The following helminths (together with their prevalence) were isolated and classified: Uncinaria criniformis (84.2%); Capillaria sp. (31.6%); Molineus patens (21.1%); Mesocestoides melesi (21.1%); Aelurostrongylus falciformis (52.6%); Crenosoma melesi (21.1%). According to results, only sex related differences in prevalence were studied. The parasite biocenosis is composed exclusively by dominant and codominant species. Mesocestoides melesi represents the first record for Italy. All the species found fitted a negative binomial distribution.

Abstract
The loss of range of motion after anterior cruciate ligament (ACL) reconstruction is one of the most common and most challenging complications of this kind of surgery. Recently, an intercondylar notch fibrous proliferation, called cyclops syndrome because of its arthroscopic appearance, has been identified as one of the specific causes of loss of extension. The incidence of cyclops syndrome is 2%-4% [17, 18], but there is still no understanding of its etiology. We speculate on the etiology and suggest some technical solutions to reduce this complication. In 180 patients submitted to arthroscopic ACL reconstruction with patellar tendon, we observed in 4 cases a fibrous nodule adherent to the neoligament that caused a loss of extension between 12 degrees and 17 degrees. In all cases, arthroscopic removal of this nodule solved completely the loss of articular motion. The nodules were subjected to light and scanning electron microscope evaluation. We observed numerous, newly formed vessels in all 4 nodules. These vessels were made up of hyperplastic and hypertrophic cells and were surrounded by bundles of disorganized fibrous tissue. No inflammatory cells or bone or cartilaginous tissue was observed. We hypothesize a microtraumatic genesis for cyclops syndrome. Repeated microtraumas expose the graft collagen fibers, which can lead to productive inflammatory process and thence to the formation of the cyclops nodule. We suggest some technical solutions to avoid graft impingement with the notch and with the tibial bone tunnel.

Abstract
The ability of ivermectin to control canine dirofilariosis in naturally infected dogs was tested. Two studies were carried out in the coast line of Grosseto district (Italy), where D. repens infection is endemic. A sample of 384 dogs from the area was examined as background controls and we found D. repens in 21.1%, D. immitis in 7.8% and both species in 6.5%. In the first study we used 72 privately-owned dogs, of varying sex, breed and age; all animals were negative to Knott's modified test for microfilariae and to CITE test for the adult antigens. All the dogs were treated monthly per os with tablets of ivermectin (> or = 6 mcg/kg) seven times from May 1991. All dogs were found negative for microfilariae 6-8 months after the last treatment. The second experiment was carried out on 16 Beagles aged 5.5-7 months (8 control dogs and 8 treated dogs). The dogs lived in a semi-open kennel in the selected area. We treated 8 dogs--8 times at monthly intervals, starting in June--with ivermectin tablets per os (> or = 6 mcg/kg). The monthly examination for circulating microfilariae (Knott's modified test) showed D. repens in two control dogs 7 months after the beginning of the experiment, one month later in 6 control and in another control animal also positive for D. immitis between the 10th and 11th month. Treated dogs were always negative. At the necropsy of all the dogs, about 11 months after the beginning of the experiment, we found adults or pre-adults of filariae in all the control dogs. Four animals had a double infection, 3 with D. repens and one with D. immitis. We never found adults or pre-adults of filariae in treated dogs.

Abstract
Among the causes of anterior knee pain, impingement of portions of the infrapatellar fat pad between the femoropatellar and femorotibial articular surfaces plays an important role. This disease, first described by Hoffa in 1904, has always been fairly obscure. This review of 63 cases delineates the clinical features, distinguishing two phases, acute and chronic, and analyzing the pathologic changes in the fat pad and the other joint structures involved. Treatment of both the chronic and acute phases is described, emphasizing the importance of arthroscopy in the chronic phase. The arthroscopic techniques are thoroughly described and commented on. Analysis of the results confirms the validity of arthroscopic surgery in the treatment of this disease.

Abstract
Rheumatological diagnosis encountered at 3 levels of the health care system primary care, district hospital and specialized centers, were registered. The prevalence of rheumatic disorders was calculated from a population survey. Back complaints were the predominant diagnosis of primary care physicians, while inflammatory diseases were the major diagnostic group seen in specialized rheumatology centers. Among in-patients at the district hospital level, back disorders and inflammatory diseases each constituted 1/2 of cases. The utilization of primary care for patients over 65 yr of age decreased for back disorders but was higher for all other types of rheumatic disorders. Young and middle aged patients were seen more frequently by specialists than older patients. Awareness of the high frequency of noninflammatory rheumatic disorders in the population and at all levels of care is important in the planning of health services for the rheumatic disorders.

Abstract
As a direct continuation of Part I, where the theoretical background for the rheological model was discussed, possible operations on the model are discussed and performed on anterior cruciate ligament preparations from rabbits. Different methods of evaluating model constants are compared and other mathematical expressions than those of the model proposed are tried and discussed. Model parts are verified and numerical values are given for certain constants.
