Abstract
Streptococcus pyogenes causes mild infections, such as pharyngitis, and severe infections, such as necrotizing fascitis. In recent years, erythromycin-resistant strains of S. pyogenes have been reported in many countries. In some areas of Italy, increased rates of erythromycin resistance were first observed in the mid-1990s. Here, we report epidemiological T serotyping, invasiveness, erythromycin resistance, and PFGE patterns of 99 S. pyogenes strains isolated at the Laboratory of Clinical Microbiology of the Second University of Naples, Italy. Regarding T serotyping, 26 of 99 strains were W+, 16 strains were U+, 16 were X+, and 14 were agglutinated by anti T serum. A low percentage revealed Y+. Twelve strains were not T serotyped. PFGE patterns showed species polymorphism; however, inside the various serotypes, we demonstrated a fair homogeneity. No correlation among invasiveness and T serotype or PFGE pattern has been shown. Twenty-two of 99 strains were erythromycin-resistant.

Abstract
Vitamin D is an essential vitamin that is synthesized when the body is exposed to sunlight or after the consumption of fortified foods and supplements. The purpose of this research was to increase the retention of vitamin D(3) in Cheddar cheese by incorporating it as part of an oil-in-water emulsion using a milk protein emulsifier to obtain a fortification level of 280 IU/serving. Four oil-in-water vitamin D emulsions were made using sodium caseinate, calcium caseinate, nonfat dry milk (NDM), or whey protein. These emulsions were used to fortify milk, and the retention of vitamin D(3) in cheese curd in a model cheesemaking system was calculated. A nonemulsified vitamin D(3) oil was used as a control to fortify milk. Significantly more vitamin D(3) was retained in the curd when using the emulsified vitamin D(3) than the nonemulsified vitamin D(3) oil (control). No significant differences were observed in the retention of vitamin D(3) when emulsions were formulated with different emulsifiers. Mean vitamin D(3) retention in the model system cheese curd was 96% when the emulsions were added to either whole or skim milk compared with using the nonemulsified oil, which gave mean retentions of only 71% and 64% when added to whole and skim milk, respectively. A similar improvement in retention was achieved when cheese was made from whole and reduced-fat milk using standard manufacturing procedures on a small scale. When sufficient vitamin D(3) was added to produce cheese containing a target level of approximately 280 IU per 28-g serving, retention was greater when the vitamin D(3) was emulsified with NDM than when using nonemulsified vitamin D(3) oil. Only 58±3% of the nonemulsified vitamin D(3) oil was retained in full-fat Cheddar cheese, whereas 78±8% and 74±1% were retained when using the vitamin D(3) emulsion in full-fat and reduced-fat Cheddar cheese, respectively.

Abstract
Over the last few years, some hemocomponents have been used advantageously in clinical neurosurgical practice, not systemically via transfusion but topically as a sealant (fibrin glue). This has diverted the attention of many authors to the role of platelets in the healing process. The combination of hyper-concentrated platelets and fibrin glue (fibrinogen, XIII factor, fibronectin) with activated thrombin produces a platelet gel that can be easily applied to "difficult" wounds. This topical use of hemocomponents has gained an important role in regenerative medicine. The authors have considered the possibility of using a preparation with a high autologous platelet concentration applied in addition to autologous bone during vertebral postero-lateral fusion. The aim of the procedure is to induce a higher rate of vertebral fusion. Between November 2007 and November 2008, 14 patients (9 men and 5 women, mean age 58.9) underwent laminectomy, vertebral stabilization and postero-lateral fusion. The number of vertebral levels involved in stabilization was: 1 in 2 patients, 2 in 5 patients, 3 in 5 patients, 4 in 1 patient and 5 in 1 patient. Platelet gel was obtained by taking 16 ml of peripheral venous blood from the patient. For this procedure two patented test tubes were used for each patient, with a capacity of 8 m each. These make up the REGEN-THT(®) (Thrombocyte Harvesting Tube) system that makes it possible to obtain 8 ml of autologous platelet gel in 40-45 min. The addition of Ca gluconate and ethanol at 95% makes it possible to obtain a preparation of plasma rich in platelets and activated thrombin with a platelet concentration five times superior to the haematic one. The platelet gel is combined with fragments of autologous bone and synthetic bone during surgical operation. To allow a comparative assessment of the degree of fusion achieved with and without application of the platelet preparation in each patient, it was arbitrarily decided to use it in only one half of the operative field. All patients underwent serial CT scans 3 and 6 months after surgery as well as plain X-rays to evaluate bone fusion. The reconstructed CT images, especially in sagittal and axial planes, permitted an evaluation of the degree of vertebral fusion and "bone growth". The fusion rate was calculated measuring the increment of bone density on CT images, by means of an evaluation of the ROI (HU) in the newly formed bone, and comparing bone density within the bone callus formed by autologous and synthetic bone alone in the one to which the platelet preparation had been added. A good rate of fusion was observed in all patients. Furthermore, a comparative analysis of ROI at 3 and 6 months after surgery demonstrated a high increase in the fusion rate during the first 3 months after surgery. After 6 months the differences in ROI between the two sides had balanced out. However, at 6-month follow-up examination, bone density in the half of the surgical field in which platelet gel had been added to autologous-heterologous bone was higher in comparison to the contralateral one. Bony neoformation after posterior-lateral arthrodesis is well-evident 3 months after surgery and usually continues gradually for the following 18-24 months. The autologous platelet preparation used seems to accelerate bony deposition and to promote tissue healing, increasing bone density at the level of posterior-lateral arthrodesis. Moreover, this preparation has low production costs and is easy to apply.

Abstract
Resveratrol is a phytoalexin with antioxidant properties. We evaluated resveratrol toxicity in swim-up selected human sperm and in rat spermatocytes and spermatids separated by the STAPUT method. Resveratrol antioxidant activity was tested against lipid peroxidation (LPO) induced by tert-butyl hydroperoxide. LPO was evaluated using the C11-BODIPY(581/591) probe and transmission electron microscopy in samples incubated with and without resveratrol. LD50 for human sperm and rat spermatids was 50 μM; spermatocytes were more sensitive to resveratrol cytotoxicity. Sperm motility increased progressively at 30 μM, 15 μM and 6 μM. 15 μM resveratrol acts against LPO, preserving sperm chromatin and plasma membranes. LPO were more marked in spermatocytes than in spermatids and the effect of resveratrol was more evident in spermatocytes. In this study, the scavenger properties of resveratrol were demonstrated in vitro in human sperm and rat germ cells, thus resveratrol could be added to the media used in assisted reproduction techniques and cryopreservation when oxidative stress is exacerbated.

Abstract
There is considerable interest in alternative/adjuvant approaches for the eradication of Helicobacter pylori using biologically active compounds, especially antioxidants from plants. In the present work, we tested the antioxidant and antimicrobial activities of hydro-alcoholic extracts from Colorino, Sangiovese and Cabernet Sauvignon grape cultivars against H. pylori G21 (cagA-negative, cagA-) and 10K, (cagApositive, cagA+) clinical isolates. We determined the minimum bactericidal concentration (MBC) by incubating strain suspensions in Brucella broth with fetal bovine serum and samples at different concentrations in a final volume of 100 microl in a microaerobic atmosphere. After incubation, subcultures were carried out on Brucella agar plates which were incubated for 3-5 days in a microaerobic environment. The lowest concentration in broth, where the subculture on agar showed complete absence of growth, was considered the MBC.The Colorino extract showed the highest antibacterial activity against G21 strain (MBC=1.35 mg/ml), while Sangiovese and Carbernet MBCs were 4.0 mg/ml ca. H. pylori 10K was only susceptible to Colorino after 48 hours (MBC = 3.57 mg/ml). Resveratrol exhibited the highest antibacterial activity. interestingly, the most pathogenic strain (10K) was less susceptible to both the grape extracts and the isolated compounds. These results suggest that the administration of grape extracts and wine constituents, in addition to antibiotics, might be useful in the treatment of H. pylori infection. Should the reduced susceptibility of 10K strain be extended to all the cagA+ H. pylori isolates, which are endowed with cancer promoter activity, this observation may help explain why the organisms expressing CagA are more closely associated with atrophic gastritis and gastric carcinoma development.

Abstract
BACKGROUND/AIMS Treatment of hepatorenal syndrome (HRS) is based on vasoconstrictors. Terlipressin is the one with the soundest evidence. Noradrenalin has been suggested as an effective alternative. The current study was aimed at assessing the efficacy and safety of noradrenalin vs terlipressin in patients with HRS. METHODS Twenty-two consecutive cirrhotic patients with HRS (9 with HRS type 1; 13 with HRS type 2) were included. Patients were randomly assigned to be treated with noradrenalin (0.1-0.7 microg/kg/min) and albumin (10 patients) or with terlipressin (1-2 mg/4h) and albumin (12 patients). Treatment was administered until HRS reversal or for a maximum of two weeks. Patients were followed-up until liver transplantation or death. RESULTS Reversal of HRS was observed in 7 of the 10 patients (70%) treated with noradrenalin and in 10 of the 12 patients (83%) treated with terlipressin, p=ns. Treatment led in both groups to a significant improvement in renal and circulatory function. No patient developed signs of myocardial ischemia. CONCLUSIONS Data from this unblinded, pilot study suggest that noradrenalin is as effective and safe as terlipressin in patients with HRS. These results would support the use of noradrenalin, a cheap and widely available drug, in the management of these patients.
