The plates were washed with PBS and blocked with 1% polyvinylpyrrolidone (Sigma, Munich, Germany) at room temperature for 1 h and then washed Selisistat ic50 extensively with PBS at 37°C for 40 min. A total of 2.5 × 105 neutrophils in 500 μL of DPBS were pretreated with rmTNF (50 ng/mL at 37°C for 15 min) and then added to the wells for 40 min. Plates were then washed gently three times with prewarmed PBS and the remaining adherent cells were quantified by counting three microscopic fields at a 40× magnification. RNA was prepared as described [44]. Briefly, murine PMNs were isolated and RNA was immediately prepared with TriFast (Peqlab, Erlangen, Germany). Reverse transcription

was performed on 1 μg of RNA using random hexamers reverse transcriptase. A total of 200 nM of the resulting cDNA was then subjected to 40 cycles of PCR in a 25 μL reaction mixtures in a BioRad cell cycler (BioRad, Munich, Germany). The PCR products were subjected to agarose gel analysis; m24p3R fw: GGC GAT TTC TAC AGG GAA TGA rv: CTA TCA GCC ACC GTG CAG ACT; mMegalin fw: TGC AUY-922 nmr ACG GAG GAA GTT GCT ATT rv: TCC ACT GTA GCC GCT AGA ACA. Rabbit polyclonal sera were raised against 24p3R. The sequences of the synthetic peptid used and

the location within the primary amino acid sequence was CDHVPLLATPNPAL (anti-24p3R: 507–520). Crude serum was affinity purified. Antibody production and affinity purification were performed by Eurogentec (LIEGE Science Park, Belgium). Protein extracts were prepared from freshly isolated human PMNs using cytoplasmic

lysis buffer (50 mM Tris-HCl, pH 7.6; 150 mM NaCl; 1% NP-40 with protease inhibitors). Ten micrograms of protein were resolved by SDS-PAGE (BioRad) and transferred to nitrocellulose membranes (Amersham Hybond-P; GE Healthcare, Buckinghamshire, UK). Membranes were blocked with 4% blocking milk/TBS/Tween and incubated with Abs against anti-human 24p3R (Eurogentec) and antiactin (Sigma). Oxyblots were performed using the Diflunisal SuperSignal West Dura Extended Duration Substrate (Thermo Scientific, Vienna, Austria) according to the manufacturer’s instructions. Freshly isolated murine blood was drawn by retroorbital puncture. Samples were stained with anti-mouse CD11b Alexa Fluor 488 (M1/70, Biolegend, Uithoorn, the Netherlands), anti-mouse Ly-6G/Ly-6C PerCP (RB6–8C5, Biolegend), anti-mouse Ly-6G FITC (1A8, Biolegend), anti-mouse CD182 PerCP/Cy5.5 (TG11/CXCR2, Biolegend), anti-mouse CD184 Alexa Fluor 647 (TG12/CXCR4, Biolegend), anti-mouse CD51-PE (RMV-7, Biolegend), anti-mouse CD62L Alexa Fluor 647 (MEL-14, Biolegend), or appropriate isotype IgGs. Cells were measured with BD FACS Calibur flow cytometer (BD Bioscience, Heidelberg, Germany) and analyzed with Kaluza Software (Beckman-Coulter, Vienna, Austria).

To assess the percentage of cell death, cells were first stained for surface markers and then with TOPRO-3 (Invitrogen) (10 nM). Following culture (day 4) CD8+ T cells were mixed with 51Chromium-labeled p815 cells in the presence or absence

of anti-CD3 OKT3 mAb (5 μg/mL) Opaganib clinical trial or with Caki-1 cells. In some experiments, CD8+ T cells and Caki-1 cells were co-cultured in the presence of neutralizing anti-human TRAIL (RIK-2) and/or FasL (NOK-2) mAb (10 μg/mL). Cytotoxity activity of CMVpp65495–503-specific CD8+ T cells was assayed against control or CMV peptide-pulsed 51chromium-labeled HLA-A2+ T2 cells. 51Chromium release was counted in a Topcount (Packard). Lysis percentage was calculated as [(experimental release-spontaneous

release)/(maximum release-spontaneous release)]×100. Lysis by CD3-redirected cytotoxicity was also depicted as Lytic units (LU) (number of effector cells needed to lyse 3000 targets cells) calculated by the formula LU=[1/(E:T50%)]×3000, where E:T50% is the E:T ratio at which 50% of lysis occurred. E:T50% was inferred from the killing curve (Lysis versus E:T ratio). The percentage of specific lysis was calculated after deduction of the non-specific lysis (in the presence of control peptide or IgG) from the total lysis in the presence of specific peptide or OKT3 mAb. Data were analyzed first by the Shapiro Wilk Normality test and then by Paired T or Wilcoxon selleck chemicals signed-rank Liothyronine Sodium test, depending on whether the data were or were not from a normally distributed sample, respectively. All tests were two-tailed and conducted at 95% of confidence.

Cardiovascular Biology and Pharmacology, Graduate School of Medicine, Ehime University, Japan; 4Institute of Anatomy and Cell Biology, Selleck Autophagy inhibitor University of Wuerzburg, Germany Introduction: Sympathetic hyperactivity is a hallmark in various pathophysiological conditions including hypertension, insulin resistance, obesity and diabetes. Recent studies showed that renal sympathetic denervation (RDX) improves glucose metabolism and insulin sensitivity in addition to reducing blood pressure in patients with resistant hypertension. However, the mechanisms underlying the beneficial effects of RDX are poorly understood. Here, we investigated the outcomes of RDX at diabetic

stage on glucose Selleck Opaganib metabolism and blood pressure profiles in obese type 2 diabetic rats. Methods: Male Otsuka Long Evans Tokushima Fatty (OLETF) and Long Evans Tokushima Otsuka (LETO) were underwent uninephrectomy at 5 week of age followed by RDX at 25 week of age. Results: RDX animals had almost undetectable renal cortical tissues norepinephrine (NE) levels. Enzalutamide RDX at diabetic stage attenuated mean arterial pressure, systolic and diastolic blood pressures, and non-significant trends to lowered heart rate in OLETF rats measured by telemetry system. RDX-OLETF rats showed reduction in blood glucose, plasma insulin levels and their area under the curve in response to oral glucose loading during the oral glucose tolerance test compared to non-denervated sham operated rats. Furthermore, the whole body insulin sensitivity was assessed by the hyperinsulinemic-euglycemic clamp study at

45 week of age, and RDX-OLETF rats showed an improved glucose infusion rate compared to non-denervated sham operated rats. RDX suppressed plasma and renal tissues NE levels, lowered urine NE excretion, and improved in vivo glucose uptake by adipose tissues, soleus muscle and liver tissues in OLEFT rats. Furthermore, RDX suppressed sodium dependent glucose transporter 2 (SGLT2) translocation and expression in renal proximal tubular brush border membrane followed by overt glycosuria in OLETF rats. Conclusion: In conclusion, renal sympathetic denervation at diabetic stage ameliorates impaired glucose metabolism, insulin sensitivity, and attenuates blood pressure through suppressing sympathetic hyperactivity resulting increased glucose uptake by peripheral tissues, and suppressed glucose transporter expression leading to enhanced glycosuria in obese type 2 diabetic rats.

In the thymus, CCRL1 is abundant in cTECs but not mTECs or thymocytes [20]. In fetal mice, CCRL1 regulates the migration of thymocyte precursors before vascularization [19]. It has been reported that CCRL1 deficiency results in thymus enlargement in adult mice, in association with altered thymocyte development and autoimmunity [21]. Thus, CCRL1 is important for optimal thymus homeostasis and normal thymocyte development. To analyze the expression of CCRL1 in TECs during embryogenesis,

Ribeiro et al. [18] use CCRL1-EGFP-knockin mice, in which EGFP is expressed under the control of CCRL1 gene expression [20]. By crossing CCRL1-EGFP-knockin mice with IL-7-YFP-transgenic Selumetinib clinical trial mice, and by flow cytometry analysis of embryonic TECs, the authors show that CCRL1 expression progressively increases during fetal cTEC development. The emergence of CCRL1-EGFPhigh cells, which are class II MHChigh CD40high cTECs, is diminished in RAG2/IL2Rγ double-deficient mice, in which thymocyte development is arrested at an early stage. From these results, the authors conclude that CCRL1high cTECs represent late-appearing mature cTECs, and that the development of those mature cTECs is regulated by

the signals provided by developing see more thymocytes. These results agree with previous reports showing that thymocyte-derived signals are necessary for the late maturation of cTECs [4-6]. Ribeiro et al. [18] also show that CCRL1+UEA1–CD80– cTECs isolated from E15.5 fetal thymus give rise to UEA1+CD80+ mTECs, when cultured in the presence of RANK and CD40 stimulation in RTOCs, suggesting that CCRL1+ fetal cTECs contain mTEC progenitor activity. These results agree with the recent reports discussed above showing that pTECs progress through a stage in which they express cTEC-associated molecules before diversifying into mTECs [11, 14-16] (Fig. 1). Perhaps Cediranib (AZD2171) more interestingly, Ribeiro et al. [18] go beyond the confirmation of other studies to report that CCRL1-EGFPlow cells in the thymus are not restricted to CD205+ Ly51+ cTECs but also contain UEA1+ mTECs, despite the fact that CCRL1-EGFPhigh cells are

limited to cTECs but not mTECs. The CCRL1-EGFPlow CD80+ UEA1+ mTECs were detectable only after birth. Gene expression analysis showed that this late-appearing subpopulation of mTECs, which was identified by the CCRL1-EGFPlow CD80+ phenotype, contained large amounts of Aire and RANK mRNAs but a nondetectable amount of CCL21 mRNA. Ribeiro et al. [18] further demonstrate that the combination of RANK and CD40 signals, the ligands of which are produced by positively selected thymocytes [8, 10], is important for the development of CCRL1-EGFPlow mTECs. Thus, the analysis of CCRL1-EGFP reporter mice suggests a novel heterogeneity in postnatal mTECs. It has been shown that mTECs are heterogeneous in terms of the expression of various molecules, including class II MHC, CD80, Aire, and CCL21 [22-26]. White et al.

“Cranial fasciitis is a rare lesion of young children characterized by proliferation of fibroblastic spindle cells. Most are scalp masses and are only rarely intracranial, where an association with radiation therapy is exceptional. We report a 32-month-old toddler

with a facial rhabdomyosarcoma, diagnosed at 3 months of age, and treated with surgery, chemotherapy and brachytherapy. Brain MRI at 28 months revealed a large, left parasagittal, dural-based, T2 hyperintense and T1 hypointense enhancing mass with superior sagittal sinus compression and bony hyperostosis. The mass was completely resected during an open craniotomy. Histologically, the lesion was comprised of loosely and haphazardly arranged bland spindle cells embedded in a myxoid background. Thick hyalinized collagen bundles were especially prominent. The spindle cells reacted for vimentin but not SMA, Lumacaftor concentration myogenin, MyoD1 or EMA. A diagnosis of cranial fasciitis was rendered. The role of radiation therapy in the pathogenesis of intracranial cranial fasciitis is discussed. “
“JC virus (JCV) granular neuronopathy remains an under-appreciated

phenomenon whereby JCV inhabits neurons in the granular layer of the cerebellum causing neuronal loss, gliosis and a clinical cerebellar syndrome. The following Adriamycin concentration case describes a man with sarcoidosis and idiopathic leukopenia who developed a clinical cerebellar syndrome due to JCV granular neuronopathy, followed by neurological decline due to rhombencephalic progressive multifocal leukoencephalopathy. This case reminds us of the ability of JCV to produce dual neuropathology which includes JCV granular neuronopathy, and the pathogenesis and clinical implications for this phenomenon are discussed. “
“An unusual case of intraparenchymal

myofibromatosis of the brain occurring in a 29-year-old woman is described. Preoperative CT and MRI examinations revealed two well-circumscribed nodular masses localized in the wall of the left lateral ventricle and right temporal lobe, respectively. Both masses were completely resected, and the patient remains disease-free 2 years post-surgery. Histopathologically, the lesions were characterized by stratification. From outer Proton pump inhibitor to inner, there was a reactive glial component, lamellated well-differentiated muscle-like cells, densely compact collagen fibers and cellular tumor with nodular and hemangiopericytoma-like patterns, respectively. The myofibroblastic nature of this tumor was verified by immunohistochemical staining and ultrastructural analysis. Intraparenchymal myofibromatosis may be confused with, and should be distinguished from, meningioma, myopericytoma, solitary fibrous tumor, leiomyoma and inflammatory myofibroblastic tumor for accurate diagnosis and optimal treatment. “

“The purpose of this study is to report our experience and learning curve in avoiding complications at both

the recipient and donor sites as well in choosing the best flap for different anatomic locations. For this purpose 155 free flaps done between October 2005 and August 2012 were retrospectively examined. Selleck Ixazomib Patient demographics, flap types, etiology, re-exploration indications, timing of the re-explorations, and salvage rates were documented. In the first 60 cases, our re-exploration rate was 26.7% (16 flaps), and the rate decreased to 15.0% for the second 60 flaps (9 flaps). In correlation with this decrease, in the last 35 cases, only three flaps were re-explored (8.6%). This decrease in re-exploration rates over time was statistically significant (P = 0.021). Re-exploration rates for axial and perforator flaps were 14.6% and 22.7%, respectively. Salvage rates

were 76.9% in axial flaps and 53.3% in perforator flaps. The total success rate for axial flaps was 95.5% and for perforator flaps was 89.4%. Besides, re-exploration rates were higher with lower salvage rates in perforator flaps compared to axial flaps causing lower overall success rates in the former group. The mean selleckchem time of re-explorations was 21.4 hours. Salvage rates were significantly higher in re-explorations done within the first 12 hours after the initial surgery than P-type ATPase in re-explorations done after 12 hours (83.3% vs. 47.3%) (P = 0.040). We can conclude that axial flaps have a steeper learning curve and are safer options for the inexperienced reconstructive micro-surgeons until they have adequate experience with the perforator dissection. © 2013 Wiley Periodicals, Inc.

“The esthetic outcome is dictated essentially not only by

the position, size, and shape of the reconstructed breast, but also by the extra scaring involved. In the present study, we conducted a visual analog scale survey to compare the esthetic outcome in delayed autologous breast reconstruction following two different abdominal flaps inset. Twenty-five patients had their reconstruction using the Single-esthetic Unit principle and were compared with 25 patients that their breast was reconstructed using the Two-Esthetic Unit principle. Photographic images were formulated to a PowerPoint presentation and cosmetic outcomes were assessed from 30 physicians, by means of a Questionnaire and a visual analog scale. Our data showed that the single-esthetic unit breast reconstruction presents significant advantages over the traditional two-esthetic units, due to inconspicuous flap reconstruction, better position of the inframammary fold, and more natural transition from native and reconstructed tissues.

MA, USA Astragalus polysaccharides (APS), extracted from the root of Astragalus membranaceus, a traditional Chinese medicinal herb, have extensive pharmacological and strong immunomodulatory effects. In this study, the potential adjuvant effect of APS on humoral and cellular immune responses to hepatitis B subunit vaccine was investigated. Selleck Mitomycin C Coadministration of APS selleck products with recombinant hepatitis B surface antigen significantly increased antigen-specific antibody production, T-cell proliferation and CTL (cytotoxic T lymphocyte) activity. Production of interferon-γ (IFN-γ), interleukin-2 (IL-2) and IL-4 in CD4+T cells and of IFN-γ in CD8+T cells were dramatically increased. Furthermore, expression of the genes PFP, GraB, Fas L and Fas were up-regulated; interestingly, expression of transforming growth factor

β (TGF-β) and the frequency of CD4+CD25+Foxp3+ regulatory T cells (Treg cells) were down-regulated. Expression of Toll-like receptor 4 (TLR4)

was significantly increased by administration of APS. Together, these results suggest that APS is a potent adjuvant for the hepatitis B subunit vaccine and can enhance both humoral and cellular immune responses via activating the TLR4 signaling pathway and inhibit the expression of TGF-β and frequency of Treg cells. Hepatitis B is a potentially life-threatening liver disease caused by hepatitis B virus (HBV) infection. It is a global health problem and the most serious type of viral hepatitis (Chisari & Ferrari, 1995). More than 350 million people worldwide are chronic HBV carriers, and 1–2 million people die each year due to the consequences of chronic hepatitis B (Rehermann, 2005). To date, the commercial recombinant hepatitis B surface antigen (HBsAg) vaccine has been widely used, and has become an effective strategy for preventing HBV crotamiton infection. However, the vaccine primarily induces the antibody response and Th2-biased immune response, but elicits relatively weak cell-mediated immune responses, particularly the antigen-specific CTL response. Therefore, it is unable to clear the virus in the infected cells (Zhang et al., 2009; Geurtsvan et al., 2008). Astragalus membranaceus (Huangqi) is a well-tolerated and nontoxic traditional medicinal herb that is used as a therapeutic agent to treat many diseases in China (Luo et al., 2009; Cui et al., 2003).

1B). Splenic Treg cells from mice with EAE produced IL-17 at a similar frequency, indicating that there was no systemic perturbation in the capacity of Treg cells to produce IL-17 during EAE. However, the frequency of IL-17+ cells was markedly lower in the Treg-cell population sampled from the inflamed CNS of those same mice with EAE (Fig. 1B and C) and was reflected in the level of IL-17 detected in these cultures (Fig. 1D). As Th1-associated effector cytokines act as negative regulators of

Th17 differentiation, we tested whether CNS-Treg cells produced IFN-γ, but found no evidence for this under any conditions tested, including exposure to IL-12 (Supporting Information Fig. 1). Bisulphite sequence analysis of CpG motifs Rapamycin in vitro within the Treg-specific demethylation region (TSDR) revealed complete demethylation in both splenic and LY2606368 CNS-Treg cells (Fig. 1E), a pattern associated with natural Treg cells rather than the incomplete demethylation seen among in vitro generated iTreg cells [[4]]. Therefore, epigenetic differences at

the TSDR did not account for the inability of CNS-Treg cells to produce IL-17. Previous studies have shown that the increased proportion of Foxp3+ T cells in the CNS during EAE is not due to the peripheral conversion of Foxp3− T cells to Foxp3+ adaptive Treg cells [[5]]. Our analysis of the TSDR supports this view. IL-6 can drive IL-17 production by naïve T cells and by Treg cells [[2, 6]]. The IL-6 receptor is composed of an IL-6-specific α chain (CD126) coupled with the signaling chain gp130, which is shared with other cytokine receptors (reviewed in [[7]]). Cells lacking surface expression of the Elongation factor 2 kinase IL-6R can also respond to IL-6 bound to the soluble form of the IL-6Rα, which then binds gp130 at the cell surface to provide IL-6 trans-signaling [[8]]. Peripheral Foxp3− and Foxp3+ T cells from naïve mice responded rapidly to either IL-6 or hyper DS s-IL-6R (HDS), an IL-6-sIL-6R fusion protein that triggers trans-signaling [[9]], as measured by the appearance of pSTAT1 and pSTAT3 (Supporting Information Fig. 2). However, unlike their

splenic counterparts, CNS CD4+ cells from mice with EAE showed no expression of pSTAT1 or pSTAT3 after incubation with either IL-6 or HDS (Fig. 2A). Notably, this insensitivity was evident on all CNS CD4+ cells and was not restricted to the Treg-cell population. The relative resistance of induced Treg cells to the induction of IL-17 production has been correlated with their loss of IL-6 receptor expression [[10, 11]]. Reduced CD126 expression on CNS CD4+ cells would account for their insensitivity to IL-6, but they would be predicted to maintain responsiveness to IL-6 trans-signaling if they still expressed gp130. We found that both GFP+ and GFP− CD4+ cells from the CNS showed markedly reduced levels of both CD126 and gp130 in comparison with their splenic counterparts from the same mice (Fig. 2B and C).

Additionally, one set of samples was pretreated with vehicle Pexidartinib purchase or 10 mM dimedone for 1 h prior to stimulation and sulfenic acid labeling. For immunoprecipitation experiments, 2–4 × 106 purified B cells were stimulated with 10 μg/mL anti-IgM and lysates were prepared as previously described by Michalek et al.

[14]. Briefly, cells were washed with PBS prior to lysis in the presence of DCP-Bio1 and lysates were precleared for 1 h at 4°C with protein G beads (Dynal). Following magnetic bead removal, lysates were incubated with 2.5 μg/mL anti-SHP-2 (BD Pharmingen), anti-SHP-1, or anti-actin (Santa Cruz Biotechnology) at 4°C with constant rotation overnight. The following day, protein G beads were added and the lysates were rotated at 4°C for 3 h. After discarding the supernatant, the magnetic beads were washed three times, resuspended in lysis buffer, and protein was eluted by boiling in reducing sample buffer (Pierce). Affinity capture of biotinylated proteins was performed according to Nelson et al. [47]. Samples were boiled with reducing sample buffer, separated on a 10% precast SDS denaturing gel, and transferred to a PVDF (polyvinylidene fluoride) membrane. The GSK-3 beta pathway membrane was blocked and probed with anti-PTEN (Cell Signaling) or anti-CD45 (Santa Cruz Biotechnology) according to the manufacturer’s protocol. For sulfenic acid

detection, samples lysed in the presence of 1 mM dimedone were separated on a 10–12% precast SDS denaturing gel and transferred to a PVDF membrane. The membrane was blocked and incubated with anti-dimedone antibody (Millipore) according to the manufacturer’s protocol. Proteins were visualized as previously described [14]. The blot was stripped and probed with anti-actin.

To quantify sulfenic acid, actin and cysteine sulfenic acid levels were normalized between samples using a Kodak Image Station 4000R and Carestream CYTH4 Molecular Imaging Software. The entire length of the gel lane was used to determine sulfenic acid levels. Only the protein band was used for actin. The sulfenic acid signal was then normalized to actin protein levels. Detection of sulfenic acid during immunoprecipitation experiments was performed as previously described [14]. Briefly, samples lysed in the presence of 5 mM DCP-Bio1 were separated on a 7.5–15% SDS denaturing gel and transferred to a PVDF membrane. The membrane was blocked overnight at 4°C with 5% FCS in tris buffered saline supplemented with 0.1% Tween-20 (TBS-T). The following day, the membrane was washed three times and incubated with 1:50,000 dilution Streptavidin-HRP (Southern Biotech) in 5% FCS in TBS-T for 1 h at room temperature. After washing, the membrane was developed as previously described [14]. CFSE (5–6-carboxyfluorescein diacetate, succinimidyl ester, Molecular Probes) was resuspended in DMSO at a 5 mM stock and stored at −20°C. Purified B cells were washed with cold PBS three times and resuspended in PBS at 20 × 106 cells/mL. The CFSE stock solution was diluted in PBS to 6.

Condyloma incidence.  England and Wales implemented registration of condylomas in the 1970s, but condyloma surveillance has not been conducted in other countries. Consequently, the epidemiology and public health burden of condylomas is not well known. However, symptomatic condylomas appear to be quite common and the age-specific incidence curve of first-attack condyloma appears to be similar to Chlamydia incidence. As the incubation time from exposure to clinical condyloma

is between 3 and 12 months, and because some 90% of condylomas are caused by HPV types included in the quadrivalent HPV vaccine, reduction in the occurrence of condylomas in sexually active young populations is the first clinical end-point see more that can be detected following implementation of the quadrivalent HPV vaccine. In Australia, where rapidly a high coverage with quadrivalent vaccine was built up, a significant CHIR-99021 supplier decrease in incidence of genital warts was observed among young women (≤26 years) and heterosexual men, but not among older women and homosexual men [88]. If a reduction in condylomas

is not seen, then this will serve as an early warning that the control of HPV infection is not adequate and prompt investigation of possible reasons for the failure, such as inadequate population coverage, type-replacement or vaccine breakthrough. Cervical screening results.  For Europe, the proportion Metformin mouse of low-grade cervical dysplasia attributable to HPV vaccine types has been estimated to 26% and the proportion of high-grade cervical dysplasia to be greater than 50% [89]. With incubation times from 1 to 4 years, effective control of HPV should

result in a significant decline in the burden of screen-detected precursor lesions requiring follow-up and treatment on medium-term follow-up. To use screen-detected lesions as an end-point for vaccine surveillance requires that screening practices and methods are not impacted by vaccination. In addition, determining the types that are associated with these lesions will be required, and that in turn will rely upon HPV typing of these lesions. Clinical HPV assays differ from HPV assays used in epidemiological studies as well as in vaccine clinical trials in that they have a lower sensitivity and do not commonly provide type-specific results. Therefore, clinical results may not be optimally informative for surveillance. We suggest that strategies using residual clinical samples could be developed, whereby a random sample of positive and negative samples could be retested with quality-assured HPV typing assays. HPV-associated malignancies.  A recent IARC review concluded that essentially all cervical cancer is HPV-associated; the proportion of cancers in other anatomic sites that are HPV-associated varies: penis 40%, anus 90%, vulva/vagina 40% and oropharynx 12% [90].
