The balance of inflammation, innate immunity and adaptive immunit

The balance of inflammation, innate immunity and adaptive immunity interfacing with the complex commensal biofilms, controlling pathogens that emerge in the biofilms, minimizing NVP-BEZ235 manufacturer local collateral tissue damage from chronic inflammation and down-regulating systemic responses to the infections remain ill-defined. The commensal opportunistic pathogens provoke both a localized and systemic response during the disease [39–41], with systemic inflammatory responses being generally low in individuals with a healthy periodontium or in subjects with reversible gingival inflammation (i.e. gingivitis) and increasing in periodontitis

patients [40,42]. Thus, an interaction between the systemic responses to periodontitis and the changes that occur during pregnancy could be predicted to increase the risk of adverse pregnancy outcomes [43–45]. The objectives of this study were to document profiles of various systemic inflammatory mediators in female baboons during their pregnancy resulting from ligature-induced periodontitis. The targeted mediators would be those that could contribute to adverse pregnancy outcomes and might be predictive of the biological risk linking periodontal disease with these events. These data should contribute to the development of a pathway that explores the contribution Selleck Autophagy Compound Library of oral infection and systemic host responses to birth outcomes using a non-human primate model. An experimental cohort of 288 Papio anubis (168 experimental; 120

controls) were examined in this study. Inclusion in the study is dependent upon the following criteria: (i) dams must have a minimum of 20 teeth; (ii) be in good general health based upon an examination by the veterinarian; (iii) range in age from 6–13 years; and (iv) have produced previous offspring. Mothers were excluded if they demonstrated systemic illness that required veterinary

treatment during the course Prostatic acid phosphatase of the project that would adversely impact the pregnancy outcome (i.e. infection) and/or administration of antibiotic and/or anti-inflammatory therapy, which could confound the onset and severity of periodontitis. Loss of body weight ≥15% also excluded the baboon from further participation in this project. Nulliparous dams (e.g. previous births increase likelihood of successful breeding for this study), dams of extreme ages, either younger or older, and those dams having fewer than 20 teeth were excluded. The animals were sampled prospectively at three time-points during the study. The study design has been described previously [46]; briefly, however, the experimental animals were sampled at baseline (clinical examination, serum) and teeth in quadrants one and four were ligated. A second sampling took place at mid-gestation (∼3 months) into the pregnancy and ligatures were tied on the contralateral maxillary and mandibular quadrants (quadrants two and three). The third sample was obtained from 2 to 10 days after delivery and the ligatures were removed.

Cells were rapid desensitized as

Cells were rapid desensitized as Dinaciclib per Table 1. After desensitization (nearly 2 h) cells were maintained for 10 min, 2 hours, or 4 hours at 37°C. After each time period, 1 ng of DNP-HSA or 25 μL of calcium ionophore A23187 (Sigma-Aldrich) 10 μM was added. Non-desensitized cells were kept at 37°C and challenged with 1 ng of DNP-HSA or 1 ng HSA at the same time points as for desensitized cells. The total time for all cells at 37°C, since rapid desensitization protocol lasts nearly 2 h, was 6 h. Cell viability

was assessed by trypan blue dye exclusion. After desensitization or challenge, cells were collected and washed with cold PBS. Pellets were lysed in RIPA buffer supplemented with protease and phosphatase

inhibitor cocktails (Roche). Total protein lysates were subjected to SDS-PAGE on a 4–12% polyacrylamide gel and transferred to a nitrocellulose membrane (both from Invitrogen). Membranes were blotted with anti-Phospho-STAT6 (phosphotyrosine 641) and anti-STAT6 from Sigma-Aldrich or with anti-Phospho-p38MAP kinase and anti-p38αMAP kinase from Cell Signaling. Signal detection was performed with SuperSignal West Pico Chemiluminescent Substrate (Pierce). After desensitization or challenge, cells were placed at 4°C, then washed and resuspended in PBS containing 0.5% BSA and 0.05% sodium azide at 4°C and incubated with anti-FcγRI/II mAb (eBioscience) for 20 min on ice to block Fcγ receptors. Cells were then incubated with CB-839 chemical structure 5 μg/mL FITC rat anti-mouse IgE (BD Biosciences) or 2 μg/mL PE Armenian hamster anti-mouse FcεRIα Adenosine triphosphate (eBioscience) or with the recommended isotype controls. Cells were analyzed on a BD Biosciences FACSCanto flow cytometer, using FACSDiva acquisition software and FlowJo analysis software.

Antigens used were Alexa Fluor 488-conjugated OVA (Molecular Probes) and DyLight Fluor 649-conjugated DNP, labeled with DyLight 649 NHS Ester (Thermo Scientific). Due to detection limitations, OVA activation dose was 50 ng, DNP activation dose was 5 ng and the rapid OVA desensitization protocol was consequently adjusted based on the volumes used in the protocol in Table 1 but at higher concentrations. After desensitization or challenge, cells were washed and resuspended in cold PBS. Cells were transferred onto poly-L-lysine-coated round cover slips for 20 min at 4°C and then fixed with 4% paraformaldehyde in PBS for 10 min at 4°C. After three washes with PBS, cells were incubated with cholera toxin subunit B-Alexa Fluor 555 conjugate (Molecular Probes) 1:500 in PBS for 10 min at 4°C, washed three times with PBS and mounted using an aqueous mounting medium (15% wt/v polyvinyl alcohol, 33% v/v glycerol, 0.1% azide). Images were collected sequentially using a 63× plan Apo NA 1.4 objective on Leica SP5X laser scanning confocal system attached to an inverted Leica DMI6000 microscope.

2 mM each dNTP, 2.5 U Taq, 2.5 μL of BSA (0.1 g/10 mL) and 1 μM for each forward and reverse primer in a total of 50 μL reaction volume was used. A total of 35 cycles, each consisting of 94°C for 45 s, 59°C for 45 s, and 72°C for 1 min, were performed; PF-02341066 in vitro an initial hot start at 94°C for 3 mins and a final extension step at 72°C for 7 mins were also included. For the secondary PCR step, the PCR mixture was identical except that a concentration of 1.5 mM MgCl2 was used. A total of 40 cycles, each consisting of 94°C for 30 s, 58°C for 90 s, and 72°C for 2 mins, were performed; an initial hot start at 94°C for 3 mins and a final extension step at 72°C for 7 mins were also included.

PCR products were analyzed on 1% agarose gel and visualized by ethidium bromide

staining. The PCR products were purified using the terminator V3.1 cycle sequencing kit (Applied Biosystems, Foster, CA, USA). Sequences were assembled using the SeqMan program (DNASTAR, USA). The characteristics of study participants are presented as mean and percentage. As appropriate, Student’s t-test was used to compare the means of continuous variables, whereas categorical variables were compared using Fisher’s exact test or Pearson’s Napabucasin X2 test. A logistic model was used to assess any association between potential risk factors and Cryptosporidium spp. infection; P < 0.02 according to univariate analysis was considered significant and is presented with the OR. Wald's test was used to assess the significance of variable associations. Correlations between exposure and outcome that considered possible confounding variables were evaluated by multivariate analysis by means of a logistic regression model. Only variables with P < 0.05 on Wald's test were included in the multivariate model; a backward deletion process was used. Analyses were carried out using computer software SPSS ver.12 (SPSS, USA). For both univariate and multivariate

analyses, associations were considered significant at P < 0.05. We studied 183 immunocompromised patients. Endonuclease Their medical conditions were HIV infection in 47 (25.7%), ALL 43 (23.5%), AML 13 (7.1%), CLL 18 (9.8%), various solid cancers 22 (12%), NHL 11 (6%), post-bone marrow transplant 13 (7.1%) and post-renal transplant 16 (8.7%). One hundred and fifty one patients (82.5%) were male and 32 (17.5%) female. The majority of patients (72.7%) were over 30 years old, non-diarrheic (87%), had CD4 + T-cells counts > 100 cells/mm3 (93.4%) and were urban dwellers (76%). We considered patients had Cryptosporidium infection if their fecal samples contained typical oocysts of 4–6 μm when examined after using a modified acid-fast staining technique. We identified oocysts of Cryptosporidium in the feces of 11 of the 183 patients (6%). Demographic, environmental and clinical characteristics of the studied patients are shown in Table 1. We identified two genotypes, C.parvum and C.hominis, by 18s rRNA gene amplification, sequencing and analysis. We identified C.

“Transplanted bone marrow stromal cells (BMSC) promote functional recovery after spinal

cord injury (SCI) through multiple mechanisms. A Rho kinase inhibitor, Fasudil also find more enhances axonal regeneration. This study was aimed to evaluate whether combination therapy of BMSC transplantation and Fasudil further enhances axonal regeneration and functional recovery in rats subjected to SCI. Fasudil or vehicle was injected for 2 weeks. BMSC or vehicle transplantation into the rostral site of SCI was performed at 7 days after injury. Neurological symptoms were assessed throughout the experiments. Fluoro-Ruby

was injected into the dorsal funiculus of the rostral site of SCI at 63 days after injury. The fate of the transplanted BMSC was examined using immunohistochemistry. BMSC transplantation significantly increased the number of Fluoro-Ruby -labeled fibers of the dorsal corticospinal tracts at the caudal site of SCI, enhancing functional recovery of the hind limbs. Some of the engrafted BMSC were positive for Fluoro-Ruby, neuronal specific nuclear protein selleck kinase inhibitor and microtubule-associated protein-2, suggesting that they acquired neuronal phenotypes and built synaptic connection with the host’s neural circuits. Fasudil treatment also improved axonal continuity, but did not promote functional recovery. Combination therapy dramatically increased the number of Fluoro-Ruby-labeled fibers

of the dorsal corticospinal tracts at the caudal site of SCI, but did not further boost the therapeutic effects on locomotor function by BMSC transplantation. The findings suggest that BMSC transplantation and Fasudil provide synergistic effects on axon regeneration after SCI, although further studies would be necessary to further enhance functional recovery. “
“J. Satoh, H. Tabunoki, T. Ishida, Y. Saito and K. Arima (2012) Neuropathology and Applied Neurobiology38, 132–141 Immunohistochemical characterization of γ-secretase activating protein expression in Alzheimer’s disease brains Aims: A recent study AZD9291 showed that γ-secretase activating protein (GSAP), derived from a C-terminal fragment of pigeon homolog (PION), increases amyloid-β (Aβ) production by interacting with presenilin-1 (PS1) and the β-secretase-cleaved C-terminal fragment of amyloid precursor protein (APP-CTF). In the study, knockdown of GSAP reduces production of Aβ and plaque formation in the brain of APPswe and PS1ΔE9 double transgenic mice without affecting the Notch-dependent pathway. Therefore, GSAP is an ideal target for designing γ-secretase modulators with least side effects in Alzheimer’s disease (AD). However, at present, the precise distribution of GSAP in AD brains remains to be characterized.

Indeed, there is a strong evidence that pathogens easily adhere to the ETT made of polyvinylchloride, and following the development of organized biofilm, they translocate into the airways because of the inspiratory airflows generated by the mechanical ventilator and invasive procedures, such as bronchoscopy 3-Methyladenine concentration and tracheal aspirations (Diaz-Blanco et al., 1989; Inglis et al., 1989, 1995; Feldman et al., 1999). These early studies used scanning electron microscopy (SEM), which allows the characterization

of the biofilm tridimensional structure, but lacks functional information and optical sectioning. In contrast, CLSM allows a comprehensive examination of biofilm layers at different depths, real-time imaging of developing biofilm (Yarwood et al., 2004; Gunther et al., 2009), and, with the use of selective dyes, analysis of bacterial viability (Cook et al., 2000; Kim et al., 2008). Previous studies assessing ETT biofilm through confocal microscopy have provided qualitative bacterial viability analysis, particularly after antimicrobials exposure (Cook et al., 2000; Perkins et al., 2004; Berra et al., 2008; Kim et al., 2008; Rello et al., 2010). Nevertheless, only few studies applied quantitative analysis of biofilm bacterial viability (Auty et al., 2001; Yang et al., 2008; Cairns et al., 2011), and to the best of our knowledge, quantitative bacterial viability assessment

of ETT biofilm by CLSM has never been carried out. The aim of this study was to quantitatively assess, through CLSM, bacterial viability Talazoparib within ETT obtained from a pig model of severe methicillin-resistant

Staphylococcus aureus (MRSA) pneumonia, undergoing different antimicrobial therapies, to compare the bacterial killing rate achieved with each treatment. In addition, we aimed to describe structural inherent characteristics of ETT bacterial biofilm, using both CLSM and SEM. Finally, we compared the in vitro capability to form biofilm between the planktonic MRSA, inoculated into the pigs, and MRSA isolates retrieved from within the ETT. We evaluated eight 7.5-mm-internal diameter ETT (Mallinckrodt Hi-Lo®; Mallinckrodt Medical, Athlone, Ireland) obtained upon extubation of eight pigs with severe MRSA pneumonia and mechanically ventilated for 72 ± 20 h (mean ± SD; Table 1). Pigs were challenged with Phosphoprotein phosphatase 75 mL solution of 106 CFU mL−1 of pathogenic MRSA. Instillation of MRSA was performed through the working channel of a bronchoscope FB14-V Pentax Europe GMBH (Sistemas Integrales de Medicina SA, Madrid, Spain) and evenly distributed into every lobe of each lung. The experiment was carried out for 96 h. Animals were euthanized at the end of the 96-h study or earlier based on the severity of the infection (Martinez-Olondris et al., 2012). Four of these pigs received placebo, 0.9% saline (controls), two underwent therapy with linezolid (10 mg kg−1 every 12 h IV), and two were treated with vancomycin (15 mg kg−1 every 12 h IV).

An internal standard is used to ensure precision in mass determination. The result is that the Ibis

universal biosensor detection system can identify the amplicons produced by a carefully designed primer set, with a high degree of accuracy that is stated as a percentage in the ‘read out’ data and with a sensitivity that detects all organisms present as >1% of the total microbial population in the sample. The system also detects and identifies fungi and viruses, and detects the presence of the bacterial genes that control resistance to antibiotics. Primer sets can be designed DNA Damage inhibitor to focus on the pathogens usually seen in a particular medical situation, such as orthopedic infections, so that sensitivity and accuracy can be enhanced in the parts of the bacterial ‘tree of life’ (Fig. 5) in which the majority of the ‘usual suspects’ are located. The time required for DNA extraction is short, except in exceptional cases, and the PCR amplification process is rapid and automated, so that the Ibis system can detect and identify all of the bacteria present in a sample in <6 h, and biofilm cells are detected with the same sensitivity as planktonic cells. We have initiated prospective

double-blinded studies of both suspected infections of total joint prostheses, and of infected nonunions of the tibia/fibula following open trauma, in which we will compare data obtained from cultures with data generated using the Ibis system. Clinical decisions will be based on culture data because the Ibis system is not yet FDA approved, but after the code has been broken, HKI 272 the sensitivity and accuracy of the Ibis system will be compared with that of cultures. In addition, the Ibis data will be considered retrospectively, as a potential basis for clinical decisions, in the light of clinical outcomes and in the light of additional evidence of the presence of bacterial biofilms, such as direct microscopic evidence using FISH probes. If Amylase the sensitivity and accuracy of the Ibis system are seen to exceed those

of traditional cultures, we will support their adoption for the diagnosis of bacterial infections in all aspects of orthopedic surgery. “
“Here, we report on the successful programming of dendritic cells (DCs) using selectively applied mixtures of chemokines as a novel protocol for engineering vaccine efficiency. Antigen internalization by DCs is a pivotal step in antigen uptake/presentation for bridging innate and adaptive immunity and in exogenous gene delivery used in vaccine strategies. Contrary to most approaches to improve vaccine efficiency, active enhancement of antigen internalization by DCs as a vaccine strategy has been less studied because DCs naturally down-regulate antigen internalization upon maturation. Whereas chemokines are mainly known as signal proteins that induce leucocyte chemotaxis, very little research has been carried out to identify any additional effects of chemokines on DCs following maturation.

Moreover, in 2003 Allan et al described that inhibition of caspa

Moreover, in 2003 Allan et al. described that inhibition of caspase-9 is mediated through phosphorylation by Erk 36. Our observation that inhibition of either Erk 3 or SphK (Fig. 3) each results in strongly reduced cytokine release from CXCL4-stimulated monocytes, extent corresponding findings for TNF-activated monocytes

and C5a-treated macrophages 15, 16. Having in mind that in CXCL4-treated monocytes cytokine release as well as rescue from apoptosis are regulated by SphK1 as well as Erk the question arise whether these molecules might regulate each other. By investigating this possibility Natural Product Library in vitro in more detail, we could clearly demonstrate that Erk phosphorylation is totally blocked in SKI-treated monocytes (Fig. 5), indicating that Erk is located downstream of SphK. Finally, the finding that high dosages of S1P reduce apoptosis rates in monocytes might be related to its ability to induce Erk phosphorylation (Fig. 6D). The activation of Erk by SphK or S1P has been reported by others too. Monick et al. as well as Chandru and Boggaram demonstrated that in lung epithelial cells treatment with S1P leads to the phosphorylation of Erk 37, 38. According to our results, S1P mediates

only a partial but significant reduction of apoptosis (compared with unstimulated cells; Fig. 6A), which might be the result of a shorter duration of Erk activation as compared with the more prolonged Erk phosphorylation induced by CXCL4 (Fig. 6D). Taken R428 research buy together, we identified SphK1 as an essential signaling element in CXCL4-induced monocyte activation. By several lines of evidence

we could Hydroxychloroquine in vitro demonstrate that CXCL4-mediated ROS formation, as well as cytokine/chemokine expression, and rescue from apoptosis depends on SphK1 activity. Furthermore, our data indicate that the protective effect of CXCL4 on monocyte survival involves sequential activation of SphK and Erk resulting in an inhibition of caspase activation. Further studies will address the question by which mechanisms CXCL4 regulates SphK activity and whether SphK/S1P is involved in CXCL4-induced monocyte differentiation. Human natural CXCL4 was purified in our laboratory from release supernatants of thrombin-stimulated platelets, as described previously 39. Antibodies directed against Erk1 p44 (serum K-23; cross-reactive to Erk2 p42), and phospho-Erk (clone E-4) were purchased from Santa Cruz Biotechnology (Heidelberg, Germany), while anti-SphK1 antiserum was purchased from ABGENT (Bioggio-Lugano, Switzerland). Alexa680-conjugated goat anti-mouse IgG was obtained from MoBiTec (Göttingen, Germany), and IRDye800-conjugated goat anti-rabbit IgG was from Biotrend (Köln, Germany). Inhibitors directed against SphK (SKI; 2-(p-hydroxyanilino)-4-(p-chlorophenyl) thiazole 17, or DMS), MEK/Erk (PD098059; 2′-amino-3′-methoxyflavone), Gi proteins (PTX), and D-erythro-S1P were purchased from Calbiochem (Schwalbach, Germany).

Mean serum creatinine and estimated glomerular filtration rate at Pembrolizumab chemical structure 1 year was 115 ± 25 μmol/L (range 63–192) and 66 ± 15 mL/min per 1.73 m2 (range 37–102) respectively. Twenty-two episodes of biopsy proven acute rejection occurred in 18 recipients (25.7%). Three patients (4.2%) had acute tubular necrosis; however, only one (1.4%) had delayed graft function. One patient, with focal segmental glomerulosclerosis had recurrence of native kidney disease. Thirty-two episodes of urinary tract infection were observed in 22 recipients (31.4%), and Escherichia coli was the most commonly isolated organism, 17 (53.1%) out of 32 episodes. New onset diabetes mellitus after transplant occurred in 16 recipients (22.8%).

“Aim:  Vitamin D deficiency is highly prevalent in end-stage renal disease and has been associated

with atherosclerosis, endothelial dysfunction and left ventricular hypertrophy. Although Quizartinib activated vitamin D has shown to be cardioprotective, the cardiovascular benefits of nutritional vitamin D (i.e. ergocalciferol or cholecalciferol) have not been explored in the dialysis population. The aim of this investigation was to evaluate the effect of ergocalciferol therapy on vascular adhesion molecules, markers of inflammation and atherosclerosis among haemodialysis patients. Methods:  This was a pilot study of matched haemodialysis patients. For every patient enrolled taking ergocalciferol, an age and race matched control was recruited. Predialysis blood samples were collected and assayed for adhesion molecules (soluble vascular cell adhesion molecule-1 (sVCAM-1), soluble intercellular adhesion molecule-1 (sICAM-1),

E-selectin and P-selectin), inflammatory cytokines (interleukin-6 Cytidine deaminase (IL-6) and tumour necrosis factor-α (TNF-α)), oxLDL-β2GPI and IgG anticardiolipin. Results:  A total of 40 haemodialysis patients were studied (20 on ergocalciferol therapy, 20 not receiving ergocalciferol therapy). Patients taking ergocalciferol had higher 25-hydroxyvitamin D levels compared with those not taking ergocalciferol. Even though doxercalciferol usage and dosing was similar between groups, plasma sVCAM-1, sICAM-1 and P-selectin concentrations were lower among ergocalciferol treated patients. No significant differences in E-selectin, IL-6, TNF-α, oxLDL-β2GPI or anticardiolipin antibody levels were observed. Conclusion:  Patients receiving ergocalciferol had lower plasma levels of vascular adhesion molecules despite equivalent use of activated vitamin D therapy.

PBMCs from RSA patients and fertile women were isolated from hepa

PBMCs from RSA patients and fertile women were isolated from heparinized peripheral blood by density gradient centrifugation on Ficoll-Hypaque (Amersham Pharmacia Biotech, Uppsala, Sweden) between days 17 and 26 from the first day of the last regular menstrual period. Cells were washed extensively and resuspended in RPMI-1640 (Life Technologies, Grand Island, NY, USA), supplemented with 10% human serum, glutamine and

penicillin–streptomycin. Endometrial samples were obtained between days 17 and 26 (mean 21·6 days) from the first day of the last menstrual period in women with regular, 28-day cycles. To confirm Torin 1 timing in the mid-luteal phase of the menstrual cycle, peripheral blood was obtained from all subjects at the time of endometrial biopsy for

measurement of serum oestrogen and progesterone levels. Endometrial samples were obtained using a Novac curette and disrupted mechanically with a tissue homogenizer. The recovered cells were resuspended in RPMI-1640 medium (Life Technologies) supplemented with 10% human serum, 2 mM L-glutamine, Z VAD FMK 100 U/ml penicillin and 100 U/ml streptomycin. Total endometrial cells were analysed by flow cytometry. The Investigation and Ethics Committee from the Argentinean Society of Gynecological and Reproductive Endocrinology (SAEGRE) approved this study and all patients provided an additional written consent to participate. Trophoblast cells (Swan-71 cell line, derived by telomerase-mediated transformation of a 7-week human cytotrophoblast isolate, described by Straszewski-Chavez) [22, 23] were cultured in 24-well flat-bottomed polystyrene plates

(Becton Dickinson, Franklin Lakes, Tyrosine-protein kinase BLK NJ, USA) in complete Dulbecco’s modified Eagle’s medium (DMEM) 10% fetal calf serum (FCS) (Gibco, Invitrogen, Buenos Aires, Argentina). For co-cultures, trophoblast cells at 70% of confluence (2 × 105 cells/well) were cultured in the absence/presence of PBMCs from RSA patients or from fertile women (5 × 105 cells/well) with or without VIP (10−7 M), and VIP antagonist (Peninsula-Bachem Inc., San Carlos, CA, USA; 10−6 M) in several combinations. This peptide, a hybrid of neurotensin (6–11) and VIP (7–28), is a competitive antagonist of VIP receptors [24, 25]. After 48 h of culture, supernatants were collected for enzyme-linked immunosorbent assay (ELISA) determinations and maternal PBMCs were recovered and then used for flow cytometry or Western blot analysis. Interleukin (IL)-10 and monocyte chemotactic protein-1 (MCP-1) were assayed by ELISA in supernatant collected from the co-cultures performed in the presence of RSA PBMCs or fertile PBMCs during 48 h. The ELISA test was performed according to the manufacturer’s instructions (Becton Dickinson for IL-10 and R&D Systems, Minneapolis, MN, USA for MCP-1 quantification). Results were expressed in ng/ml.

“There is a propensity for fungal adherence to the polymethylmethacrylate used for making denture bases. Therefore, this study investigated whether surface modifications with plasma treatments would reduce the adherence of Candida albicans to a denture base resin. Samples (n = 180) with smooth and rough surfaces were made and divided into five groups: control – non-treated; experimental groups – submitted to plasma treatments to obtain surfaces with different hydrophobicities (Ar/50 W; ArO2/70 W; AAt/130 W) or with incorporated fluoride (Ar/SF670 W). Selumetinib supplier KPT-330 nmr Contact angles were measured immediately after treatments and after samples were immersed in water for

48 h. For each group, half the samples were incubated with saliva before the adherence test. The number of adhered C. albicans was evaluated by counting after crystal violet staining. The plasma treatments were effective in modifying the polymethylmethacrylate surface. However, there was a significant alteration in the contact angle measured after immersion in water. No statistically significant difference in the adherence of C. albicans was observed between the experimental and control groups, irrespective of DNA ligase the presence or absence of saliva, and surface roughness. “
“Dermatophytosis is still being considered as one of the major public health problems in wrestlers. Objectives: To identify the prevalence, clinical pattern, aetiological agents and the predominant transmission route of dermatophytoses in Iranian wrestlers, a study was carried out in 2008. In total, 270 wrestlers from eight wrestling salons were evaluated. Classical mycological techniques were performed on 135 skin scraping samples of 110 wrestlers suspicious for dermatophytoses

and 240 touch preparation samples of wrestling mats. Diagnosis of the fungus type was made based on macroscopical and microscopical characteristics of the colonies. 19.2% of the evaluated wrestlers were inflicted with tinea gladiatorum. The head and neck were the most prevalent (36.5%) areas of involvement, followed by arms and forearms (28.8%), trunk (21.2%), as well as groin and knee (13.5%). The mean age of patients was 21 years and the most frequent age group was 10–19 years (51.9%). Trichophyton tonsurans was the most frequently isolated species representing 82.7% of isolates, followed by T. rubrum (5.8%), T. mentagrophytes var. interdigitale and Epidermophyton floccosum (3.8% each), and T. mentagrophytes var. mentagrophytes and T. verrucosum (1.9% each). Of 24 wrestling mats surveyed, 33.3% were heavily contaminated with T. tonsurans.
