At her next review 4 months later Mrs A brought her daughter and an interpreter attended. The uncertainty of her prognosis was discussed again and Mrs A indicated that she did not wish to discuss her end-of-life care preferences with Dr Y but that she had done so with her family. Her daughter commented that it was really useful having

the interpreter whose command of Samoan was much better than her own. The following month Mrs A was found to have liver cirrhosis with complications including ascites and rectal varices, her multiple medical problems this website made her unsuitable for intervention for the varices. Later that month Dr Y met with Mrs A in clinic, this time with her husband and her eldest son, the two people Mrs A identified as her chosen surrogate decision-makers, as well as an interpreter. From this consultation an Advance Care Plan emerged. Dr Y wrote a summary of the discussion on a hospital ACP pro forma. Dr Y met with Mrs A and an interpreter to go through this Plan and modified it with Mrs A. Mrs A then took written information (in English) on ACP home, along with her unsigned Plan. Mrs A met with her husband and five of her children at home and reviewed the Plan and information before returning the Plan for Mrs A and Dr Y to sign and enter in the hospital record. Over

the ensuing 6 months EPZ-6438 Mrs A deteriorated in health and was hospitalized recurrently. Four months after the plan was written she was referred to community palliative care services, largely Celecoxib for family support. It was identified that Mrs A had a strong desire to be reacquainted with a child who had been adopted out and was living overseas. The community palliative care team and Dr Y were able to assist with the paperwork required to expedite this person’s immigration visa. Mrs A withdrew from dialysis 6 months after writing her Plan when it became technically impossible to achieve an adequate treatment. She was cared for at home surrounded by her family and with input from community palliative care services until her death. Although

Mrs A was competent to participate in the decision to withdraw from dialysis and her written Advance Care Plan was therefore not referred to, the process of ACP was felt by nephrology staff and the family to have been worthwhile. The nephrologist conducting the final family meeting in hospital commented that the family and patient were very well prepared. Mrs A’s eldest son, reflecting on her death 6 months later, commented that the plan was the ‘best thing ever’. It articulated what their mother wanted rather than what they thought she wanted, particularly the importance of her spirituality and faith. He felt that having had the opportunity to reunite his mother with his brother was especially valuable. His mother had also communicated with them how she wanted to spend her last days after she stopped dialysis and they shared some special time fulfilling these wishes for her.

Bonferroni P = 0·705, P = 0·403, P = 0·147; respectively]. find more The study design and procedures were approved by the local Human Ethical Committee, following the ethical guidelines of the most recent Declaration of Helsinki (Edinburgh, 2000), and all participants gave their written consent. All serum samples were stored at −20°C until analysed and apoTf levels were measured by the nephelometric method (Siemens Mod BNTM: BN 100) and the radial immunodiffusion method performed on plates ‘NOR Partigen Transferrin’ (Siemens, Erlangen, Germany). Calibration curves were obtained with the calibrator N Protein Standard SL and the sensitivity limit of the test was 0·513 g/l. Continuous variables were expressed as mean ± s.d. and Student’s t-tests were used to compare continuous variables between groups. All analyses were two-tailed and performed using spss version 18·0 for Macintosh (IBM Company, Chicago, IL, USA). P-values <0·05 were

considered statistically significant. Overnight exposure of pancreatic islet and RINm5F cells to a cytokine cocktail, including IFN-γ, IL-1β AZD1152-HQPA molecular weight and TNF-α, decreased significantly cell viability measured using the MTT assay. When recombinant apoTf was added to the experimental setting, it protected pancreatic islets significantly, as well as insulinoma cells, from the deleterious effect of the cytokine cocktail (Fig. 1). As mentioned previously, two models of type 1 diabetes were used to dissect the role of apoTf on disease onset. In the first model, untreated DP-BB rats developed type 1 diabetes based on glycosuria and blood glucose levels higher than 200 mg/dl in 11 of 14 cases (79%) within 12 weeks (Table 2 and Fig. 2a). In contrast, the prophylactic treatment with 5 mg/kg human apoTf reduced type 1 diabetes prevalence significantly by 12 weeks (64·3% versus 79%; P < 0·05) (Fig. 2a) and delayed the age of diabetes Oxalosuccinic acid onset

(88·9 ± 6·8 days versus 78·6 ± 6·6 days in control rats; P < 0·01) (Table 2). Recombinant apoTf at doses of 2·5 and 1·25 mg/kg was not associated with statistically significant differences in diabetes phenotype in this rat model. In the second type 1 diabetes rodent model, control NOD mice developed diabetes by 11 weeks of age with glycosuria and blood glucose levels higher than 200 mg/dl observed in 63% of mice by the end of the study (Fig. 2b). In contrast, the treatment of the mice with apoTf at 0·1, 1 and 2·5 mg/kg for 12 consecutive weeks led to a significant reduction (12·5% with 0·1 mg/kg dose) or complete prevention (with higher doses) of type 1 diabetes onset (Fig. 2b).

In addition, although the number of total PBDCs and myeloid DCs w

In addition, although the number of total PBDCs and myeloid DCs was decreased significantly in secondary SS patients, the number was distributed more widely than that in primary SS patients (Fig. 2a,b). Based upon these findings, we hypothesized that the number of PBDCs in secondary SS might

be influenced or determined by the autoimmune diseases that overlap with SS. Therefore, we compared the number of total PBDCs, myeloid DCs and plasmacytoid DCs in each subgroup of secondary SS (five SLE-merged secondary SS, 11 RA-merged secondary SS and eight SSc-merged secondary SS) with that in each corresponding primary autoimmune disease and in normal controls. There was no significant difference in the number of total PBDCs, myeloid DCs and plasmacytoid DCs

among SSc-merged secondary SS (total PBDCs: mean 17 855/ml; myeloid DCs: mean 8959; plasmacytoid selleck compound DCs: mean 8897), RA-merged secondary SS (total PBDCs: mean 15 866; myeloid selleck screening library DCs: mean 8137; plasmacytoid DCs: mean 7729) and normal controls. PBDCs, myeloid DCs and plasmacytoid DCs were all decreased significantly in SLE-merged secondary SS (total PBDCs: mean 6358; myeloid DCs: mean 2863; plasmacytoid DCs: mean 3495) (Table 1). The number of total PBDCs, myeloid DCs and plasmacytoid DCs in each subgroup of secondary SS was similar to that in the corresponding primary autoimmune disease that overlaps in each subgroup of secondary SS. Furthermore, we analysed the PBDC numbers of primary SS and secondary SS which were compared with RA and SLE. The total numbers of PBDC and myeloid DC were decreased significantly in primary and secondary SS patients in comparison with RA, which was similar

to healthy donors, but not with SLE (Fig. 2a,b). Meanwhile, the numbers of total PBDCs and plasmacytoid DCs in secondary SS were significantly larger than those in SLE. These results might be due to the decreased plasmacytoid DCs in SLE. The decreased number of PBDCs in primary SS is restored naturally during the clinical course. In our previous report, we put forward a hypothesis that the decrease of PBDCs might be a critical most event in the pathogenesis of primary SS [2]. Thus, in this study we examined whether the decrease of PBDCs continues during the natural course of primary SS. As shown in Fig. 3a–c, a direct correlation was observed between the number of PBDCs and the time from onset of Sicca syndrome in primary SS. None of the 29 patients received therapeutic agents, including corticosteroids. In addition, six of the 29 patients with primary SS were examined twice sequentially for PBDC numbers (Fig. 3g–i). Four of the six patients and all six patients showed an increase in the number of total PBDCs and myeloid DCs, respectively, after an average of 43 months from the initial examination. However, plasmacytoid DC numbers did not show a distinct alteration in all the six patients.

Monolayers of Madin-Darby canine kidney cells in 12-well plates were incubated with 0.1 mL of the dilutions for 1 h, and the cells were overlaid with 1.5 mL of agar medium. The plates were maintained

in a humidified atmosphere containing 5% CO2 for 2 days, and the plaques in wells were counted. The virus titers of the lungs were expressed as the number of pfu per unit weight of lung. The left lobes of lungs were fixed in 10% neutral buffered formalin solution, sectioned, and stained with hematoxylin and eosin. Histopathological RG7204 order scores were established on the basis of the extent of the histopathological findings including hypertrophy, hyperplasia, abruption and necrosis of bronchial epithelium, infiltration of inflammatory cells in bronchial submucosa

and alveolar septa, exudation of inflammatory cells in alveolus, atelectasis, edema, and hemorrhage in the alveolus. Each histopathological finding was scored as follows: 0, normal; 1, mild; 2, moderate; and 3, severe. Histopathological scores were estimated from the average of the extent of these findings. Data are expressed as mean ± SD, and P < 0.05 indicated significant differences as determined by Student’s t-test for comparisons between groups. A total of 85 strains consisting of 57 strains from 16 species of Lactobacillus, 14 strains from 5 species of Bifidobacterium, 8 strains from 2 species of Lactococcus, 4 strains from 2 species of Enterococcus, and 2 strains from 1 species of Streptococcus were examined for their ability to induce IL-12. Murine splenocytes were cultured with heat-killed

bacteria (1 μg mL−1) for 2 days and the levels of IL-12p70 in supernatants were determined Molecular motor (Fig. 1). Lactobacillus paracasei MoLac-1 most strongly induced IL-12. Heat-killed MoLac-1 induced IL-12p70 and IFN-γ production in a dose-dependent manner between 0.1 and 1 μg mL−1 (Fig. 2). To examine the cell types exhibiting MoLac-1-induced IL-12 production, the IL-12 production by splenocytes depleted of various cell populations was compared with that of complete splenocytes. We prepared splenocytes depleted of CD90.2+ cells (mainly T cells), B220+ cells (mainly B cells), CD11b+ cells, CD11c+ cells (mainly dendritic cells), and DX5+ cells (mainly NK cells and NKT cells). Splenocytes and the depleted splenocytes were cultured with heat-killed MoLac-1 (1 μg mL−1) for 2 days. The secretion levels of IL-12 induced by MoLac-1 were diminished in CD11b− cells but maintained in the other subsets of splenocytes depleted of CD90.2+ cells, B220+ cells, CD11c+ cells, or DX5+ cells (Fig. 3a). CD11b is expressed on macrophages/monocytes, granulocytes, NK cells and subsets of dendritic cells. Using Ly-6G, a marker expressed on granulocytes, we found that Ly-6G− cells produced IL-12 induced by MoLac-1 (Fig. 3b).

For the agonist mode, CHO cells were incubated with reference compounds at 0·01 pM–100 μM final concentration with 10 μM forskolin for 30 min. After incubation, detection mixture

(cAMP-D2 and cAMP-antibody-Europium) was added following the time-resolved fluorescence Wnt inhibitor resonance energy transfer (TR-FRET) dynamic-2 cAMP kit (Cisbio, Bagnols-sur-Cèze, France) instructions. After 1 h incubation, cAMP levels were read on Envision (Perkin Elmer). For the antagonist mode, CHO-FPR2/ALX cells were preincubated with reference compounds at 0·01 pM–100 μM final concentration 1 h prior to adding 10 μM forskolin and the agonist at the effective dose (EC80) (20 nM and 0·05 nM for compound 43 and WKYMVm peptide, respectively). After 30 min of incubation, cAMP levels were measured as in the agonist mode. All incubations were performed at room temperature.

FPR2/ALX this website cell membranes (2 μg) were incubated in a 200 μl total volume containing 20 mM HEPES pH 7·4, 100 mM NaCl, 10 mM MgCl2, 10 μM GDP, 50 μg/ml saponin, 0·2% BSA (Sigma, Saint Louis, MI, USA) and 0·1 nM [35S]-GTPγS (NEN; specific activity 1250 Ci/mmol). For agonist mode, reference compounds were incubated with the membranes for 90 min with gentle mixing. Briefly, the reaction mixture was filtrated through GF/C filter plates (Millipore, Billerica, MA, USA) using the Manifold Filtration System (Millipore). The filters were washed immediately six times with 200 μl of sodium phosphate buffer pH 7·4. After drying the filter plates for 20 min at 65°C, 30 μl of Optiphase Hisafe II scintillant liquid were added to each well and [35S]-GTPγS were measured on a Trilux Scintillation Counter. For antagonist mode, reference compounds were preincubated with membranes for 1 h before selleck kinase inhibitor addition of the agonist compound 43 at the EC80 (716 nM). After 90 min incubation, the same protocol as in the agonist mode was used for [35S]-GTPγS detection.

All incubations were performed at room temperature. Competition binding experiments were conducted in 96-well polypropylene plates in a total volume of 200 μl using 0·62 nM of [3H]-LTD4 and 7·5 μg/well of CHO-CysLT1 membranes (ES-470-M, Euroscreen; Perkin Elmer, Waltham, MA, USA). All reagents were prepared in the binding assay buffer (20 mM Tris pH 7·4, 5 mM MgCl2), except for compounds that were dissolved in 100% dimethylsulphoxide (DMSO). Non-specific binding (NSB) was measured in the presence of 10 μM zafirlukast. After an incubation period of 30 min with gentle agitation, 150 μl of the reaction mix was transferred to 96-well GF/C filter plates (Millipore) treated previously for 1 h with binding assay buffer plus 0·05% Brij 35. Bound and free [3H]-LTD4 were separated by rapid vacuum filtration in a manifold and washed four times with ice-cold washing buffer. After drying for 30 min, 30 μl of OPTIPHASE Hisafe II were added to each well and radioactivity was measured using a Microbeta microplate scintillation counter.

Therefore, it was unexpected that mice genetically deficient in C

Therefore, it was unexpected that mice genetically deficient in CXCR3 or CXCL10 have been shown to be at least as susceptible to EAE as their immunocompetent counterparts [15-17]. Furthermore, in several studies, antagonism of CXCR3 or neutralization of CXCL10 in myelin-immunized wild-type (WT) mice either had no clinical impact or, paradoxically, exacerbated EAE [10, 18, 19]. In

published studies on the role of CXCR3/ELR− CXC chemokines in murine EAE, disease has primarily been induced via active immunization with myelin antigens emulsified in complete Freund’s adjuvant (CFA). Mice primed in this manner generate a heterogeneous learn more pool of memory T cells including IFN-γ-producing Th1 and IL-17-producing Th17 cells [20]. There is also considerable diversity in the cytokine profiles of myelin-specific T cells isolated from the blood and cerebrospinal fluid of individuals with MS [21, 22]. We have previously shown that Th1 and Th17 cells specific selleck chemical for the same myelin epitope induce clinically indistinguishable forms of EAE by invoking the expression of distinct patterns of proinflammatory mediators and

chemokines in CNS tissues [23]. Consequently, Th1- and Th17-mediated EAE respond differently to individual immunomodulatory therapies [21, 24, 25]. In addition, there is accumulating evidence that Th1 and Th17 cells employ distinct homing molecules to cross the blood–brain barrier [13, 23, 26]. Therefore, the susceptibility of actively immunized mice to EAE in the absence of functional CXCR3 interactions could be secondary to the compensatory action of encephalitogenic Th17 cells, which have been reported to accumulate in the CNS via a CCR6/CCL20-dependent pathway [26]. We speculated that, under conditions where immune responses are more uniform and highly polarized, the relative importance of CXCR3/CXC chemokine interactions might vary based on the Th bias of the peripheral autoreactive T-cell repertoire. In the current study,

we used an adoptive transfer EAE model to investigate whether CXCR3 and/or its ligands are viable therapeutic targets for the treatment of inflammatory demyelinating disease mediated by a Th1-skewed Calpain effector cell population. Consistent with previous reports [15-17], we found that CXCR3−/− and CXCL10−/− mice on a C57BL/6 background readily succumb to EAE induced by active immunization with myelin oligodendrocyte glycoprotein (MOG)35–55 in CFA. Furthermore, disease incidence, the clinical course, and degree of CNS infiltration did not differ significantly between knockout mice and their WT counterparts (Fig. 1A, B, E, and F). Splenocytes and draining LN (dLN) cells harvested from MOG-immunized WT, CXCR3−/− and CXCL10−/− mice mounted comparable IFN-γ and IL-17 recall responses upon antigenic challenge ex vivo (Fig. 1C and G).

For CD4 T-cell enrichment, single cell suspensions from periphera

For CD4 T-cell enrichment, single cell suspensions from peripheral LN of TCR-transgenic TS-1 and control BALB/c mice were stained with biotinylated Ab to CD8, CD11b, CD19, GR-1 (all in-house generated), and CD49b (BD bioscience), followed by anti-biotin Ab coupled to MACS beads (Miltenyi Biotec) and isolated by autoMACS (Miltenyi Biotec). CD4

T-cell purities were >96% as determined by staining with anti-CD4 and anti-CD3 Ab. Recipient BALB/c mice received 2.3×106 CD4 T cells from either BALB/c or TS-1 donors 12 h prior to infection. Cell suspensions in medium (RPMI 1640, 292 μg/mL L-glutamine, 100 μg/mL penicillin/streptomycin, 10% heat-inactivated fetal calf serum, 0.03 M 2-ME) were placed in duplicates at 106 cells/well into ELISPOT plates (MultiScreen HA Filtration; Millipore) coated with sucrose-density gradient-purified influenza A/PR8. Twofold serial dilutions in medium were

performed. Virus-specific ELISPOT assay were done as described previously 32 revealing with either Ig (H+L)-biotin (Southern Biotech) or with anti-C12Id-biotin (23-1 Id). Mean spot counts±SD/106 input cells were calculated from all wells with countable spots. Virus-specific ELISA was done as previously described 32. For C12Id virus-specific ELISA 3% phosphate buffered PFA solution (pH 7.2) was used following serum incubation to crosslink Ag–Ab complexes and enhance sensitivity of the assay 24. Relative virus-specific Ig units were calculated by Vasopressin Receptor comparison to a standard hyperimmune serum 47. Relative virus-specific Ab concentrations were calculated from PD0325901 in vitro a standard virus-specific IgG C4Id+ mAb (clone H37-41-7) or a virus-specific IgG C12Id+ mAb (clone H35-C12.6.2) both purified from tissue-culture supernatant by protein G affinity chromatography. One relative unit was arbitrarily defined as equivalent to binding of 1 μg/mL of the relevant mAb. ELISA plates were measured on a SpectraMax

M5 (Molecular Devices) ELISA reader, and data were analyzed using Soft MaxPro software (Molecular Devices). Statistical analysis was done using a two-tailed un-paired Student’s t-test with the help of Prism 4 software (GraphPad Software, San Diego, CA, USA).

“B-cell-derived interleukin-10 (IL-10) is known to act in a paracrine fashion to suppress inflammation.

2%, n = 3). Rejection of donor BM-derived cells was greatly inhibited in the positive control group (killing rate mean ± SD = 31.3 ± 3.3%, n = 3, p < 0.05) in which NK cells were depleted by anti-Asialo selleck chemicals GM1, indicating that the killing was mainly mediated by recipient NK cells in absence of T cells. Interestingly, adoptive transfer of DN Treg cells significantly inhibited the killing of donor-derived cells (Fig. 4C, mean ± SD = 58.1 ± 1.1% versus 95.4 ± 6.2% in PBS-control group, n

= 3, p < 0.05), suggesting that the transfer of DN Treg cells can effectively suppress NK cells-mediated BM rejection. Next, we further studied the mechanism of DN Treg cell-mediated NK cells suppression. DN Treg cells were purified from gld lpr, and peforin−/− mice and were used for adoptive transfer before BM transplantation. As showed in Fig. 4D and E, perforin−/− DN Treg cells have significantly crippled inhibition capability compare with DN Treg cells purified from gld or lpr mice, indicating a perforin-dependent mechanism for DN Treg cell-mediated NK-cell suppression. The dilemma that limits

the success of organ transplantation is the difficulty this website with suppressing the host immune response to the foreign graft without excessively compromising the host normal immune system. Mixed chimerism, which denotes a state of the coexistence of recipient and donor hematopoietic cells following donor BM into conditioned recipients, holds the key to solve this problem [[12, 13]]. In this study, we tried to establish mixed chimerism in an irradiation-free protocol by adoptive transfer of C57BL/6 DN Treg cells prior to C57BL/6 to BALB/c BM transplantation in combination of CY treatment (Fig. 1). The recipient TCR Vβs clones deletion (Fig. 3) and NK-cell suppression (Fig. 4) could be achieved after DN Treg-cell transfer. The results that adoptive transfer of DN Treg cells can control both adoptive and innate immunity, promote a stable-mixed chimerism, and donor-specific tolerance in the irradiation-free regimen

provide a rationale for a potentially novel therapeutic use in transplant Selleck Ponatinib tolerance induction. Numerous mixed chimerism protocols have been proposed including immunosuppressive drugs, costimulation blockade [[32, 33]], T-cell depletion [[34-36]], Foxp3+ Treg-cell application [[37, 38]]. Despite the success in rodent, large animal [[39, 40]], and nonhuman primate models [[41]], the clinical application of mixed chimerism strategy is still hindered in patients because long-lasting stable-mixed chimerism has not yet been achieved and immunosuppression and irradiation increase risk of cancer, infection, and other side effects. Apparently, more studies are required for the development of mixed chimerism for clinical use. In our previous studies, cotransplantation of BM cells and DN Treg cells, with sublethal irradiation, could suppress NK-cell function and induce stable-mixed chimerism [[24]].

Vitamin D deficiency, inflammatory activation and higher frequency of CD4+CD28null T lymphocyte population correlate with preclinical atherosclerotic changes in CKD population. These findings suggest possible linkage between vitamin D metabolism and T cell modulation – abnormalities that may contribute to development of atherosclerosis in CKD. “
“Background:  The impact of marathon running on kidney function has not been previously described. Methods:  From 425 marathon runners, 13 women and 12 men were randomly selected and cardiovascular magnetic resonance imaging (MRI) and blood/urine biomarkers were performed 4 weeks before (baseline), immediately after (peak), and 24 h after the race (recovery). Results:  Participants were 38.7 ± 9.0 years RG7204 in vitro old and completed the marathon in 256.2 ± 43.5 min. A total of 10/25 (40.0%) met the Acute Kidney Injury Network definition of acute kidney injury (AKI) based on a rise in serum creatinine. There were parallel and similar mean rises in serum creatinine and cystatin C from baseline, to peak, and return to normal in recovery. Urine neutrophil gelatinase-associated lipocalin rose from 8.2 ± 4.0 to 47.0 ± 28.6 and returned to 10.6 ± 7.2 ng/mL, P < 0.0001. Likewise, the mean urinary kidney injury molecule-1 levels were 2.6 ± 1.6, 3.5 ± 1.6

and 2.7 ± 1.6 ng/mL (P = 0.001). The mean and minimum pre- and post-IVC (inferior vena cava) diameters by MRI were 24.9, 18.8 and 25.3, 17.5 mm, respectively, suggesting that runners were not volume depleted Amoxicillin at the first post-race measurement. Conclusion:  Approximately 40% of marathon runners experience a transient rise in serum creatinine that meets criteria of AKI with a parallel elevation of cystatin C, and supportive elevations of neutrophil gelatinase-associated lipocalin and kidney injury molecule-1 in the urine. All biomarker elevations resolved by 24 h. These data suggest that AKI with a transient and minor change in renal filtration function occurs with the stress of marathon running. The impact of repetitive episodes of AKI with long-distance running is unknown. “

Growth was measured by means of a direct cell counting method and

Growth was measured by means of a direct cell counting method and pigment synthesis was photometrically assessed. Addition of glycine resulted in an exponential increase in biomass, but not in pigment production. Tryptophan as the sole nitrogen source caused distinct brown staining of the medium, without increasing biomass. Simultaneous equimolar addition of both amino acids resulted in an initial increase

in biomass as a sign of preferential metabolism of glycine, check details followed by a growth plateau and pigment production which, caused by higher biomass, occurred more rapidly than after addition of tryptophan alone. The yeast-cell morphology changed from round to oval. Addition of glycine to the tryptophan-containing liquid culture stopped pigment formation with simultaneous growth induction. These in vitro on-off phenomena depending on the nitrogen source might be significant in the pathogenesis of pityriasis versicolor: find more hyperhidrosis followed by preferential consumption of individual nitrogen sources such as glycine with exponential growth and thereafter transamination of tryptophan and TRP-dependent

pigment synthesis. “
“An early diagnosis of an invasive fungal infection is essential for the initiation of a specific antifungal therapy and to avoid unnecessary discontinuation of a baseline therapy for haematological or oncological diseases. A real-time PCR assay for the detection and strain identification of Aspergillus species from culture strains was evaluated. DNA preparation was evaluated in contaminated culture media, urine and serum. A LightCycler PCR to

differentiate various Aspergillus species Diflunisal was established. A real-time PCR assay for the detection of Aspergillus species was improved and was able to detect and differentiate medically important Aspergillus spp. The sensitivity of the test was <10 plasmid equivalents/assay. The real-time PCR assay is a useful tool for the rapid identification of Aspergillus species and might be useful as an early diagnostic tool to detect an invasive fungal infection. A real-time PCR protocol was improved by generating plasmid standards, additional generation of melting curves for species identification and the correlation between the melting temperature and the nucleotide exchanges within the used 18S rRNA gene region.

“Despite close genetic and phenotypic relationship of Candida dubliniensis with Candida albicans, its role in human disease is mostly restricted to oral colonisation, particularly among HIV-infected patients. The prevalence of C. dubliniensis in association with other disease conditions has been infrequently reported. In this study, we present data on the prevalence of C. dubliniensis among yeast species isolated from cancer patients over a 5-year period. A total of 1445 yeast isolates recovered from respiratory specimens, blood, urine and oral swabs were analysed.
