8 mmol/L) and rapidly evolving acute

kidney injury due to acute tubular necrosis (ATN; initial creatinine 120umol/L, peak at 1210umol/L on day 4 post-diving accident). The diagnosis of ischaemia-induced ATN was supported by a high urinary fractional sodium excretion of 5.5%, elevated LDH (486U/L [125–250]) and a MAG3 scan in keeping with ATN. The absence of myoglobinuria and only moderately elevated creatine kinase (maximum 893U/L [30–170]) made rhabodmyoloysis-induced find more ATN unlikely. He received supportive care with intravenous hydration, sodium bicarbonate and 100% oxygen followed by 7 sessions of hyperbaric therapy and recovered fully without needing dialysis. Conclusions: Arterial air embolism occurs when expanding gas ruptures alveolar capillaries (pulmonary barotrauma) and enters the arterial circulation as a result of rapid decompression. Clinical manifestations depend on the site of embolization and usually include neurological and respiratory symptoms but can also

involve the muscles, skin, mesenteric circulation and as shown in this case the kidneys. The diagnosis is made on clinical grounds since gas bubbles are rarely detectable on imaging. Best first aid for decompression illness is 100% oxygen therapy and supportive care but early transfer to a hyperbaric treatment unit is important as symptoms may evolve over time as in our patient. 277 HYPERKALEMIA INDUCES FAILURE OF PACEMAKER FUNCTION IN HEMODIALYSIS PATIENT N AUNG, S MAY Tamworth Base Hospital, New South Wales, Australia Background: Hyperkalemia may cause cardiac pacemaker Vadimezan cell line malfunctioning due to a reduction of the electronegativity of the resting myocardial potential. Both sensing and capture mechanisms could be temporarily affected, with possible life-threatening effects. Case Report: Mr. DT, 50 years old male with background history of End Stage Renal Failure due to diabetic nephropathy on maintenance hemodialysis, Aortic Valve Replacement, Pacemaker for third degree AV block presented to ED in a small rural hospital with lethargy and unwell. BP 82/50 mmHg, HR 22/min. ECG showed significant bradycardia

20/min with failure of rhythm to capture the pacing. Arrangement was made for urgent transfer to Metropolitan unit with pacemaker malfunction. Subsequent Urease result: K 7.6 mmol, BSL 52.8 mmol. Repeat ECG show similar finding with no classic hyperkalemia changes. Patient was treated with usual medications for hyperkalemia and commenced on insulin infusion. At the same time, Haemodialysis was commenced. After 30 minutes on dialysis, patient’s vital sign improved to BP 100/70 mmHg, HR 65/min with ECG showing normal ventricular paced rhythm. Conclusions: Hyperkalemia is a cause of acute pacemaker malfunction without classical hyperkalemia ECG change due to a failure of pacemaker sensing and capturing. Acute treatment of hyperkalemia will restore pacemaker function.

Moreover, CD4+ CD25+ CD127− T cells pre-incubated with RBV did not inhibit the proliferation of CD4+ CD25− T cells in either mixed or separated culture conditions (Fig. 5). To determine the key cytokine GSK2126458 supplier for the regulatory effects of CD4+ CD25+ CD127− T cells, we measured the levels of IL-10 and TGF-β1, the principal cytokines through which human Tregadapt cells exert regulatory activity, released from these cells after stimulation in vitro. The levels of IL-10 released from CD4+ CD25+ CD127−

T cells were decreased when they were stimulated in the presence of RBV (Fig. 6a, upper panel). In contrast, the production of TGF-β1 was not decreased significantly (Fig. 6a, lower panel). We also examined the impact of these cytokines on CD4+ CD25+ CD127− this website T cells using their neutralizing mAbs. The reduced proliferation of CD4+ CD25− T cells in the presence of CD4+ CD25+ CD127− T cells was restored when they were incubated with anti-IL-10

mAbs. In addition, the restored proliferation of CD4+ CD25− T cells when stimulated with CD4+ CD25+ CD127− T cells pre-incubated with RBV was markedly decreased when they were stimulated in the presence of recombinant IL-10. In contrast, no effect was seen when the cells were stimulated in the presence of anti-TGF-β1 mAbs (Fig. 6b). In this study, we found that RBV down-modulated the inhibitory activity of human CD4+ CD25+ CD127− T cells (Treg cells) and also found that RBV interfered with the differentiation of CD4+ CD25− FOXP3− naive Th cells into CD4+ CD25+ FOXP3+ Tregadapt cells. Although the conversion of naive Th cells into Tregadapt cells is considered advantageous Dynein in terminating excessive activation of the cellular immune response against foreign antigens, it is disadvantageous in eliminating persistent pathogen infection because the increase in

Treg cells down-modulates the pathogen-specific cellular immune response mediated by Th1 cells. Hence, the activity of RBV is considered appropriate for the elimination of persistent viral infections such as HCV, because blocking the differentiation of naive Th cells into Tregadapt cells allows the maintenance of Th1 cell activity without entering anergy, which may enhance the ability of HCV-specific CD8+ T cells to abrogate HCV-infected hepatocytes. Our results indicated that Treg cells pre-incubated with RBV did not exhibit inhibitory activity against Th cells. Although it is still debatable which naive Th cells cannot differentiate or become unresponsive in the presence of Treg cells pre-incubated with RBV, the expression of CD45RO, known to be expressed on the surface of mature T cells,[34, 35] was unchanged when Th cells were incubated with Treg cells with or without pre-incubation with RBV, suggesting that naive T cells had been already stimulated.

Nonetheless, different cuff pressures ranging between 160 and 220 mmHg did not significantly influence PORH, provided that the applied cuff pressure exceeded systolic blood pressure [79]. In conclusion, PORH is a widely used test of microvascular function when coupled with laser Doppler and provides an overall index of microvascular function, combining axon reflex, COX-dependent pathways, and probably EDHF effects. All the same, special care should be taken to avoid methodological bias. Indeed, the duration of occlusion, baseline skin temperature, and site of measurement (i.e., glabrous or non-glabrous

skin) can influence PORH amplitude and reproducibility. Full-field techniques partly overcome Barasertib these difficulties, but LDI is too slow to accurately assess the kinetics of the response over large areas, which limits its interest. Finally, LSCI has shown excellent reproducibility, but more data are needed to assess the linearity between the LSCI signal and skin blood flow. Among thermal challenges, local heating, also referred to as LTH, provides an integrated index of neurovascular and nitric oxide-dependent cutaneous blood flow regulation [25]. In healthy subjects, LTH is characterized by an initial peak within the first five minutes, a subsequent nadir followed by a sustained plateau (Figure 5). The

initial peak mainly depends on sensory nerves as it is significantly attenuated by local anesthesia [101]. Although to date, there Montelukast Sodium has been no positive evidence to support this claim, it has been suggested that CGRP [121], possibly co-released with substance P, is responsible Omipalisib purchase for this initial peak [142]. Recent work has shown that TRPV-1 channels contribute to the initial axon reflex and, to a lesser extent, to the late plateau [144]. The late plateau phase, however, is insensitive to

local anesthesia and is mostly NO-dependent [101]. The binding of heat shock protein 90 (HSP90) to endothelial NOS may be involved in the late plateau as geldanamycin (a HSP90-specific inhibitor) decreased CVC during local heating [123]. As NOS inhibition does not completely abolish the response, other contributors are thought to be involved, including norepinephrine and neuropeptide Y [100]. Recently, reactive oxygen species have been shown to play a role in plateau hyperemia by limiting the availability of NO [94]. The two independent phases of LTH imply a dichotomized analysis of the recording. Figure 5 shows the parameters that are frequently used to assess the response, i.e., peak perfusion (axon reflex-dependent vasodilation) and plateau perfusion (NO-dependent vasodilation). The issue of data expression is similar to that discussed above for PORH. Indeed, data may be expressed as raw perfusion units or CVC, as a function of baseline or scaled to maximal vasodilation. The latter form of expression may be useful when studying the initial peak [118].

HESNs were defined collectively as individuals lacking anti-HIV-1 IgG seropositivity

or evidence of infection despite frequent exposure to HIV-1 and/or repeated high-risk behaviour in areas with high HIV-1 prevalence. The seronegative description addresses the possibility that some HESN subjects may have mucosal immunoglobulin (Ig)A responses to HIV-1, but by definition all HESN subjects must be anti-HIV-1 IgG seronegative and are often also tested for the presence of HIV-1 by ultra-sensitive polymerase chain reaction (PCR). In terms of documenting exposure to HIV-1, studies of HIV-1 discordant couples and haemophiliacs have had the advantage of known exposures to quantifiable amounts of HIV-1 [21]. Nevertheless, studies of commercial sex workers GSK3235025 clinical trial and i.v. drug users have inferred exposure to HIV-1 based upon mathematical models of the frequency of high-risk activity and the prevalence of HIV-1 in the community being studied [1,18,22]. Throughout this review, we will compare and contrast the evidence for adaptive and innate responses as correlates of resistance in high-risk HESN subjects. We will also explore how mechanism(s) of innate resistance to HIV-1 in HESN subjects intersect or differ with mechanisms

of control over HIV-1 selleck replication during chronic infection. Since the first identification of HIV-specific T cell responses in HESN subjects [23], HIV-specific T cell responses have been identified in a number of high-risk uninfected individuals from multiple cohorts [3–5,14,24]. Subsequent reports confirmed the presence of antigen-specific T cell responses to HIV-1 in HESN subjects while characterizing the functional and proliferative capacity of HIV-specific T cells in these subjects [7,25–27]. Genetically, both major histocompatibility complex (MHC) class I [28] and human leucocyte

antigen (HLA) class II [29] alleles have been associated with a reduced risk of infection with HIV-1. In terms of protection, the anti-viral mechanisms utilized by T cells against HIV-1 may come in the form of direct lysis of virally Dapagliflozin infected cells or through the secretion of anti-viral factors such as chemokines/cytokines or other CD8 non-cytolytic anti-viral factors (CNAR) [30]. Together with the description of anti-HIV-specific responses in HIV-infected long-term non-progressor subjects controlling viral replication [31,32], these findings raised hope that the generation of antigen-specific T cell immune responses to HIV-1 following high-risk contact could result in protection from HIV-1 in subsequent exposures.

Although the baseline characteristics of the participants were similar, both groups showed a significant reduction in pain level and hyperaemia on the tongue mucosa (P = 0.000) after 4-week application. However, despite the reduction in hyperaemia

in the probiotic group, these improvements did not display statistically significant differences. The detection rate of Candida spp. was 100% before treatment and 8.21% in the experimental group and 34.6% in the control group after treatment. The detection rate of Candida spp. decreased (P = 0.000) in both groups and was significantly lower in the probiotic group than the control group (P = 0.038). Other analysed micro-organisms, including the decreased detection rate for Lactobacillus spp. (P = 0.049) and the increased detection rate for Staphylococcus Panobinostat epidermidis (P = 0.019), did not display consistent change trends in the probiotics group. Compared with conventional antifungal

therapies for oral candidiasis, Kinase Inhibitor Library research buy the inclusion of locally administered probiotics helped improve certain clinical conditions and reduced the prevalence of Candida spp., although the impact of probiotics on oral bacterial species remains to be further studied. “
“Faculty of Medicine, University of Ottawa, Roger Guindon Hall, ON, Canada Yeast are among the most frequent pathogens in humans. The dominant yeast causing human infections belong to the genus Candida and Candida albicans is the most frequently isolated species. However, several non-C. albicans species are becoming increasingly common in patients worldwide. The relationships between yeast in humans and the natural

environments remain poorly understood. Furthermore, it is often difficult to identify or exclude the origins of disease-causing yeast from specific environmental reservoirs. In this study, we compared the yeast isolates from tree hollows 3-oxoacyl-(acyl-carrier-protein) reductase and from clinics in Hamilton, Ontario, Canada. Our surveys and analyses showed significant differences in yeast species composition, in their temporal dynamics, and in yeast genotypes between isolates from tree hollows and hospitals. Our results are inconsistent with the hypothesis that yeast from trees constitute a significant source of pathogenic yeast in humans in this region. Similarly, the yeast in humans and clinics do not appear to contribute to yeast in tree hollows. “
“Tinea capitis in postpubertal patients is unusual and may be misdiagnosed as dissecting cellulitis. We report a case of a healthy 19-year-old Hispanic male presenting with a 2-month history of a large, painful subcutaneous boggy plaque on the scalp with patchy alopecia, erythematous papules, cysts and pustules. Although initially diagnosed as dissecting cellulitis, potassium hydroxide evaluation (KOH preparation) of the hair from the affected region was positive.

In the

first paper to describe the use of an in vitro system for assaying the suppressive see more function of Tregs it was demonstrated that Tregs suppress production of IL-2 by effector T cells and that the provision of exogenous IL-2 could overcome Treg-mediated suppression [40]. A recent study revisited this theme, demonstrating cytokine deprivation-induced apoptosis in effector T cells co-cultured with Tregs[118]. Although IL-2 is important in supporting the expansion of Th1 cells and the differentiation and survival of iTregs[27], it is now recognized that, at least in mice, IL-2 acting via signal transducer and activator of transcription 5 (STAT5) constrains the development of Th17 responses [119]. In this sense, a mechanism acting to suppress the development of a Th1 response could facilitate simultaneously the expansion of a Th17 response, which is supported Doxorubicin in vitro further by the findings that IFN-γ blockade promotes Th17 responses [120,121]. Furthermore, exposure to IL-2 during T cell activation is known to predispose cells for activation-induced cell death (AICD) [122] via the up-regulation of Fas and FasL expression [122–124]. Sensitivity to AICD is enhanced by IFN-γ[125], which may underlie the increased sensitivity of Th1 cells to AICD compared

to their Th2 counterparts [126]. The fate of ‘suppressed’ effectors and the comparative sensitivity

of Th17 effectors to AICD deserve further study. It is clear that Tregs can modulate both Th1 and Th2 effector responses during infection [41,127,128] as well as in models of autoimmunity and allergy [43,85,86]. However, the impact of Tregs on Th17 responses in autoimmunity clonidine and infection requires more detailed study. This may be because many of our infectious and autoimmune models were constructed and characterized during the tenure of the Th1/Th2 dichotomy and have been described consequently in its limited parlance. Even in those diseases in which Th17 cells are now considered key players (for example, CIA and EAE [129]), many experiments looking at the effects of Tregs on immune responses in vivo and in vitro were carried out before the full significance of the emerging Th17 subset was realized, and have not been revisited in its new light. Finally, and perhaps most significantly, the apparent lack of data on the regulation of Th17 cells by FoxP3+ Tregs may be due to our increasing recognition that these two subsets share overlapping pathways of differentiation, and it is at this level that we have focused upon Treg/Th17 interplay. A full examination of the Th17/Treg developmental relationship is reviewed elsewhere in this series [130,131]; however, the central observations are pertinent to the topic considered here.

The analysis strategy of the FACS data is depicted in Fig. 1. In brief, the forward-scatter (FSC)-A was plotted against the side-scatter (SSC)-A and an extended lymphocyte gate was drawn to select lymphocytes as well as monocyte and DC populations. Then, cells negative for live/dead (L/D) stain and positive for CD45 were gated. Subsequently, the fluorescein isothiocyanate (FITC) signal (consisting of a combination of CD3, CD8, CD16 and

CD20) was plotted against HLA-DR. Lineage-negative/HLA-DR-positive cells were selected and CD14 was used to identify CD14-positive monocytes and a population of negative cells containing DC. Within the DC population, CD123 was plotted against CD11c to select the CD11c–/CD123+ pDC and CD11c+/CD123– Selleck Neratinib mDC subpopulations. Fluorescence minus one (FMO) controls, containing all mAb except for the PE or PE-Cy7-labelled mAb, showed the same level of expression as CD83 or CD80 on fresh cells. Background expression was not increased after stimulation. Because the data showed that regardless of stimulation condition, after 8 h >95% of the cells were still found within the live/CD45+ gate, these markers selleck chemical were not included in subsequent experiments.

Instead, CD20 was used in the V450 detection channel to allow separate analysis of the B cells, as described previously [30]. The minimal number of white blood cells analysed per tube was 200 000. The minimal number of pDC, mDC and monocytes analysed were 75, 500 and 3000, respectively. A multi-step procedure was used to measure IL-12p40 mRNA expression in purified peripheral blood pDC and mDC upon TLR stimulation. First, PBMC were isolated from peripheral blood using lymphocyte separation medium (LSM) density gradient centrifugation (Organon-Teknica, Durham, NC, USA). Subsequently, partial purification of DC and monocytes was performed Dapagliflozin by depletion of CD2-, CD3-, CD8-, CD16-, CD19- and CD20-expressing

cells, using a cocktail of PE-labelled mAb, followed by incubation with BD anti-PE beads and collection of the supernatant after placing the labelled cells for 8–10 min in a BD-Imagnet. These partially purified cell preparations were stimulated with either CL097 (1 μg/ml) or LPS (1 μg/ml) for 6 h at 37°C with Golgiplug present during the last 5 h. Finally, the cells were stained with a mixture of CD20V450, CD8AmCyan, CD14ECD, CD123PerCPCy5, CD11cAPC, CD3AF700 and HLA-DRAPCCy7 mAb and pDC and mDC subpopulations were sorted on a FACSAria cell sorter, using the gate setting described above. In each experiment, between 3000 and 5000 pDC and between 5000 and 10 000 mDC were obtained. Sorted pDC and mDC fractions contained between 5–15% and 10–20% granulocytes, respectively, as examined by Giemsa staining. Sorted monocytes contained fewer than 1% granulocytes. FACS analysis on sorted populations showed monocytes to be about 90% pure with fewer than 1% pDC and fewer than 5% mDC present.

In the kidney, abundant mercury deposits were demonstrated in the epithelial cells of proximal convoluted tubules, although there were no noticeable pathological changes. In the liver, mercury deposits were detected in hepatocytes as well as Kupffer cells, but tissue

damage was not substantial. In contrast, Me-Hg-induced damage to the nervous system can be devastating. However, it never affects the system evenly: as a rule, the damage was the severest in the cerebral and cerebellar cortices, in which some parts were affected more severely than others. The brain stem was affected to a lesser extent, and the spinal cord was least affected. On the other hand, the pathology of peripheral nerves is www.selleckchem.com/products/epacadostat-incb024360.html unique in that it appears to be associated with prolonged duration of the disease: the nerves are affected only in cases other than those of acute and subacute types. The sensory nerves are damaged selectively https://www.selleckchem.com/products/byl719.html with regeneration in prolonged cases. This patient was a 64-year-old fisherman who lived in Minamata City in the southern part of Minamata Bay, which was found to be polluted with mercury from the nearby Chisso Co. Onset of disease was marked by numbness of the feet and disturbance in speech in the Spring of 1959. The patient was treated at Minamata City Hospital for pulmonary

tuberculosis during the period from May 1965 until July 1968. Neurological examination in October 1968 and December 1969 revealed slight constriction of visual fields on the temporal side, muscle rigidity, increased tendon reflexes, tremor of the fingers, dysgraphia, and adiadochokinesis. Other clinical findings included labyrinthine deafness, hyperesthesia, and hypalgesia as well as dysesthesia in the hands and regions below the knees, elevated blood pressure of 170–192 mmHg, a mask-like face, and dyskinesia. The patient died of massive hemorrhage from a gastroduodenal ulcer in January

1970. Autopsy materials from the cerebrum, cerebellum, brain stem, spinal cord, and peripheral nerves were embedded in paraffin Branched chain aminotransferase and stained with HE, and with KB and Bodian staining methods. Frozen sections were made from peripheral nerves including ventral and dorsal root nerve fibers, sciatic nerve, radial nerve and sural nerve, and stained by the Sugamo myelin and Suzuki’s axon staining methods. The Sugamo myelin stain was modified for use on frozen sections from Kultschiky’s method. Inorganic mercury was detected by photo-emulsion. The gyri of both hemispheres were atrophic and the sulci were widened. This was particularly remarkable in the calcarine cortex and pre- and postcentral gyri. The surface of the calcarine cortex showed moderate atrophy, with widening of the calcarine fissure on the coronal section. Gennari’s band on the calcarine cortex was stained pale with the KB staining method.

We observed the same preferential usage of particular TCR Vβ subsets by CD8+ TEM cells regardless if the analyses were performed on the basis of absolute numbers of CD8+ T cells per liver or on the basis of percentages of CD8+ T cells per liver IHMC. Expansions in CD8+ TEM subsets

were observed in 13 of the 18 mice (72%), with either 1 (22%), 2 (39%) or 3 (11%) different TCR Vβ expanded in each mouse. The particular TCR Vβ expanded on CD8+ TEM cells varied between individual mice, selleck inhibitor with expansions seen for all TCR Vβ except Vβ3. The observed mouse to mouse variability in the TCR Vβ profiles makes it difficult to determine correlations between immune and immune/challenged TCR Vβ repertoires. Moreover, this type of analysis permits only a single sampling, selleck chemicals llc which may not reflect fully the changes that have taken place in the expression of the TCR repertoire during the immunization and challenge of a single mouse. To address this issue, we decided to examine the CD8+ T cell subsets in peripheral blood of immunized mice, which would provide us with information

regarding kinetics of any changes that occurred during the history of Pbγ-spz immunization and challenge. As we observed previously (30), in the current study, we also detected CD8+ TEM in the blood, concomitant with a decrease in CD8+ TN cells following immunization (Figure 4). CD8+ TCM expanded following the initial priming but returned to pre-immune levels and remained stable during the immunization protocol. Nonimmunized control mice were kept for the duration of the mafosfamide 5-week experiment, and the blood CD8+ T cells showed only a negligible increase in TEM (data not shown). Thus, the appearance of TEM in the blood was in response to immunization with γ-spz. Furthermore, the timing of the appearance of TEM in the blood was similar to that observed

in the liver [(30,31), data not shown]. To determine whether the TCR Vβ expression on CD8+ T cell subsets from liver and blood was consistent within an individual mouse, we compared the TCR Vβ expression on CD8+ subsets from liver, blood (Figure 5) and spleen (data not shown). In total, eight mice were analysed and the results from four representative mice are shown. The TCR Vβ repertoire of CD8+ TN and TCM cells was conserved between individual mice, in all organs examined. In contrast, the expression of TCR Vβ by CD8+ TEM varied between individual mice. However, the pattern of expression was the same in the blood, liver and spleen of each individual mouse. Thus, at the level of TCR Vβ expression, TEM in the blood reflect the population found in the liver, and the blood CD8+ T cells can be used as a surrogate of liver CD8+ T cells. To determine whether the repertoire of CD8+ TEM cells induced by immunization with Pbγ-spz changes after challenge, we followed the TCR Vβ profiles in the blood of individual mice. In all individual mice examined, the pre-challenge profile of TCR Vβ expression by CD8+ TEM remained the same after the challenge (Figure 6).

However, the RLB assays are relatively laborious, are limited to a maximum of about 40 samples per assay, and depend on visual read-out of the hybridization signal. To overcome these drawbacks, HPV genotyping using Luminex® suspension array technology has

been developed (11–14). The Luminex®-based genotyping coupled with GP5+/6+ PCR allowed sensitive www.selleckchem.com/products/PLX-4032.html and specific genotyping of 27 mucosal HPV types in a 96-well plate format with a digital read-out (13). Moreover, a modified version of GP5+/6+ PCR was successfully introduced into the Luminex®-based assay, and showed improved sensitivity (15). A VeraCode-ASPE method was first developed for the detection of SNP in the human genome (16) and has

been applied to multiplex SNP genotyping on the Illumina BeadXpress® platform (17, 18). The ASPE primer is composed of two Daporinad in vivo distinct regions: the 5′ region that contains the capture sequence, which is used in a subsequent hybridization reaction, and the 3′ region that contains the genomic target region with a SNP nucleotide at the extreme 3′ end. For SNP genotyping, the ASPE primer that matches the SNP nucleotide to the genome is extended by the primer extension reaction and is thus labeled with biotinylated nucleotides. After the primer extension, the products are mixed with VeraCode beads, so that the capture sequence on the primer hybridizes to its complementary sequence attached to the VeraCode beads. Labeling is then carried out with a streptavidin-fluorophore conjugate, followed by scanning and detection of the fluorescent signal using an Illumina

BeadXpress® reader (Illumina Inc., San Diego, CA, USA). In this work, the VeraCode-ASPE method on the Illumina BeadXpress® platform was evaluated for its suitability as a method to detect and genotype HPV-DNA (Fig. 1). The HPV-DNA amplified by PGMY-PCR was selected as a target for the VeraCode-ASPE genotyping, as PGMY-PCR Parvulin has been validated as a sensitive and specific means for HPV-DNA amplification (19, 20). HPV-type-specific ASPE primers were designed to target the PCR amplicons of 16 HPV types (HPV6, 11, 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66 and 68) in the 3′ region (Table 1), and with type-specific capture sequences in the 5′ region. The Tm values of the HPV-type-specific sequences, the lengths of which ranged from 19 to 28 bases, were adjusted to be between 54°C and 66°C using Primer3Plus software (http://www.bioinformatics.nl/cgi-bin/primer3plus/primer3plus.cgi) thus allowing similar annealing profiles. HPV-DNA, which was provided by the HPV laboratory network in the WHO as a quality-assured authentic panel for validation of HPV genotyping, was used to assess the sensitivity and specificity of the VeraCode-ASPE HPV genotyping.
