All animal experiments were carried out within institutional guidelines (permission numbers: 1887 and 1888). FITC-, PE-, allophycocyanin-Cy7-, PE-Cy7- or biotin-conjugated mAbs specific for mouse CD4 (GK1.5), CD5 (53-7.3), CD8α (53-6.7), CD11b (M1/70), CD19 (1D3), CD21 (CR2/CR1), CD23 (B3B4), CD45R (B220; RA3-6B2) and λ1+2-LC were purchased from

BD Biosciences. Human CD10-PE (HI10a) and CD19-alloophycocyanin (HIB19) were purchased from Biolegends. Anti-human IgM-FITC (SA-DA4) was purchased from Southern Biotech. Antibodies specific for IgM (M41), κ-LC (187.1), CD93 (PB493, C1qRp), anti-mouse BAFF-R (9B9) 20 and anti-human BAFF-R (HuBR9.1) were purified from hybridoma supernatant and labeled with FITC or biotin using RAD001 standard procedures. (Biotin-labeled antibodies were revealed by PE-Cy7-streptavidin; BD Biosciences.) Staining of cells was performed as described previously 39. Apoptotic cells were determined by using an Annexin V

apoptosis detection kit (eBioscience). Flow cytometry was performed using a FACS Calibur (BD Biosciences), and data were analyzed using the Cell Quest Pro Software (BD Biosciences). For flow cytometry with five colors or for cell sorting, the FACS Aria (BD Biosciences) was used. For cell sorting, erythrocyte-depleted BM cells were stained in IMDM supplemented with 2% FBS with saturating concentrations of the appropriate antibodies. After a 30-min incubation at 4°C, cells were washed in PBS MK-1775 with 2% FBS, resuspended in filtered PBS with 2% FBS and then filtered through a 20-μm diameter nylon mesh prior to sorting. Re-analyses of sorted cells indicated that in all instances they were >98% pure. BM samples were from routine clinical specimens taken from patients at Ospedale San Gerardo (Monza, Italy). Fully informed written

parental consent was obtained in accordance with national guidelines. Total mononuclear cells (MNCs) were isolated by Ficoll gradient centrifugation. MNCs were stained for CD19, CD10, IgM and BAFF-R (mAb Hu-Br 9.1 generated in our laboratory) Oxalosuccinic acid and sorted as previously described 39. Sorted BM B cells were maintained in IMDM medium supplemented with 2% FBS, 100 U/mL penicillin and 100 μg/mL streptomycin and grown at 37°C in 10% CO2. Twenty-five micrograms per milliliter anti-κ-LC (clone 187.1) or 25 μg/mL anti-IgM (clone M41) antibody was added as indicated. Total RNA was extracted from cells using TRI Reagent® (MRC, Cincinnati, USA), and first-strand synthesis was performed with Superscript® RT kit (Roche) according to manufacturer’s guidelines. PCR for Rag-2 and β-actin was carried out with Taq polymerase (Sigma-Aldrich). For amplification of mouse Rag-2, the following primers were used: 5′-CAC ATC CAC AAG CAG GAA GTA CAC-3′ and 5′-GGT TCA GGG ACA TCT CCT ACTA AG-3′. Semi-quantitative RT-PCR was performed by serial dilutions of cDNA. The reaction conditions were 30 s at 94°C initially, 30 s at 94°C, 30 s at 64°C and 90 s at 72°C for 40 cycles, and 10 min at 72°C.

Similar findings later revealed that macrophages ingest and kill the parasites [98, 99]. Protective

immunity depended on macrophage activation as well as antibody. Protection against P. chabaudi adami was found to be independent of antibody but critically dependent on spleen T cells [100], and TNF released from endotoxin-induced macrophage activation was shown to be damaging to both lethal and CP-690550 nmr nonlethal P. yoelii parasites [101, 102]. T cells from mice successfully vaccinated against lethal P. yoelii reacted strongly to parasite antigens, with infiltration of mononuclear cells in antigen-challenged pinnae [28]; when the mice were challenged with live parasites, increased homing of mononuclear cells and parasites to the spleen and liver occurred [78]. This T-cell-dependent shift in cell traffic was interpreted to be a cell-mediated immune response against the parasites as they migrated to the

spleen and liver [79]. Macrophage activation was strongest in infections with the nonlethal P. yoelii and P. chabaudi, and significantly weaker in the lethal P. yoelii and P. berghei infections, and vaccination increased activation more with the former than the latter. It appeared that the attraction and stimulation of cytotoxic myeloid cells by T cells play an important part in the protection of vaccinated mice. This DTH T-cell

response was confirmed by the observation that the trapping of parasites, and of both BGB324 cost lymphoid and myeloid cells, in the spleens and livers of vaccinated mice increased shortly after infection [79]. Studies in vitro revealed that spleen- and liver-derived myeloid cells killed lethal P. yoelii parasites in vitro through TNF and hydrogen peroxide-dependent killing mechanisms [103], and macrophages from mice infected with nonlethal parasites and those from vaccinated mice were more cytotoxic against L929 cells than macrophages from lethal infections [104]. Stevenson and colleagues showed that depletion of macrophages in mice treated with silica significantly impaired MYO10 their ability to control P. chabaudi parasites [105]. The susceptibility of A/J mice to P. chabaudi infection also correlated with impaired macrophage activation and effector functions, including impaired expression of MHC-II, decreased production of IL-12 p70 and decreased strength of the respiratory burst [106]. Monocytes and macrophages played a significant role in the control of the early parasitaemia of both lethal and nonlethal P. yoelii infections [107]. Mice given clodronate-encapsulated liposomes to deplete them of macrophages failed to control nonlethal P. yoelii infections, suggesting that a strong early innate response was needed to control infection (107).

18 There are only a few studies that have looked at the changes in number and need for antihypertensive medications in patients with ARVD over time. In most of the studies, there is little information on maximizing the dose of a particular drug before resorting to a second drug. In the Chabova et al. study, by design all of the patients were hypertensive and had a mean BP of 157/83 mmHg while on antihypertensive therapy.15 During the follow up, the average requirement for antihypertensive medications rose significantly from 1.6–1.9 (P = 0.02) per person. There was a non-significant trend towards lower systolic and diastolic BP. Only 32.4% of the patients were taking an ACE BGB324 in vitro inhibitor and the proportion

of patients taking each class of antihypertensive medication did not differ significantly at the end of the follow-up period. Wollenweber et al. reported clinical evidence of associated symptomatic coronary disease or cerebrovascular disease in 31% of patients with mild to moderate RAS and 49%

of patients with marked or severe RAS. New symptomatic cardiovascular disease including cardiac this website failure developed in 47% of patients within 5 years.8 This study looked at a relatively young cohort of atherosclerotic patients and the patients selected for medical treatment had a milder degree of stenosis. There were no data on the type and number of antihypertensive medications or BP control. The estimated 5-year survival rate was 66.7% in patients with ARVD compared with 91% in the comparable normal population. No significant difference in survival was noted between the medical and the surgically treated group despite the more severe atherosclerotic disease in the surgical group. The elderly cohort of patients (mean age 71.8 years) in the study by Chabova et al. showed higher

DNA ligase mortality in patients with bilateral stenosis when compared with those with unilateral disease (42% vs 21.3 %; P = 0.07). Disease was identified in other vascular beds in 97.1% of patients.14 Atherosclerotic renal vascular disease is a progressive disease, with high grade stenosis (>60%), systolic hypertension (>160 mmHg) and diabetes associated with faster progression. Abnormal baseline creatinine and bilateral stenosis are associated with greater likelihood of deterioration of renal function. Patients with ARVD have increased mortality and morbidity, particularly from cardiovascular disease. Kidney Disease Outcomes Quality Initiative: No recommendation.

Sig increase in leg lean mass & eGFR Home-based exercise: Sig decrease in mean blood pressure One of the main aims in the treatment of CKD is slowing disease progression. Exercise has the ability to impact positively on many of the upstream factors p38 MAPK phosphorylation associated with the progression of kidney disease.[39] Indeed, higher levels of leisure-time physical activity are associated with slower declines in kidney function in elderly adults[40] and patients with established CKD,[28] however, evidence as to whether exercise training interventions impacts on renal function remains equivocal. In pre-dialysis patients, 12 weeks water-based Dichloromethane dehalogenase exercise[22] resulted in a small but non-significant improvement in eGFR and decrease in proteinuria. It remains unclear how more traditional aerobic and

resistance forms of exercise impact on renal function, with some studies reporting no beneficial effects on eGFR.[20, 30, 38] However, a recent study by Baria et al.[41] noted a significant improvement in eGFR following 12 weeks of centre-based aerobic training in overweight male patients with stages 3 and 4 CKD. The improvements in eGFR occurred with a significant decrease in visceral fat and mean blood pressure, both of which (obesity and hypertension) may be risk factors for the development and progression of CKD.[39] Similarly, Toyama and colleagues[42] reported significant improvements in renal function and lipid metabolism following 12 weeks of daily home based walking and one supervised cycling session per week. The improvement in eGFR was significantly associated with the concomitant increase HDL cholesterol and changes in triglycerides, which have been reported to accelerate CKD progression,[43] possibly through increased renal tissue injury by increasing oxidative stress and inflammation.[25, 44] Castaneda et al.

This led to the upregulation of IFN-stimulated genes known to enhance host resistance to virus infection [8-12]. “K” ODN also upregulate the expression of IL-6, which contributes to the activation of multiple pro-inflammatory genes Y-27632 cell line and the subsequent shift from

innate to adaptive immunity [8-12]. The current study was designed to identify the key signaling pathway(s) responsible for the upregulation of IFN-β and IL-6, as these would provide important insights into the pattern of “K” ODN mediated activation of human pDCs. Previous efforts to examine the signaling cascade(s) triggered by the interaction of TLR9 with CpG DNA focused primarily on murine myeloid DCs (mDCs), monocytes, and macrophages [13]. Studies examining the regulation of IL-6 by “K” ODN in mice documented a role for interferon regulatory factor-5 (IRF-5) and the binding of the NF-κB transcription factors p50/p65/c-Rel to the IL-6 promoter [14, 15], while IRF-1 was identified as a key mediator of IFN-β induction by “K” ODN [16]. Yet, there is reason to question whether those findings are applicable to human pDC, as there are fundamental differences in the signaling cascades utilized by mDCs versus pDCs and mice versus humans [2, 13, 17-20]. The rarity of pDCs in human peripheral blood (they constitute only 0.2–0.5% of the PBMC pool) and ease with which they become activated during the purification process

complicates their use [6, 7]. Thus, studies of human pDCs were supplemented by analyses of the human CAL-1 pDC-like cell line to provide novel insights into the regulation of TLR9-mediated activation of human pDCs. CAL-1 cells express TLR9 and mirror the response of primary human Anti-infection Compound Library pDCs to CpG ODN, as reflected by similar patterns of cytokine induction [12, 21, 22]. siRNA knockdown studies identified the transcription factors IRF-5 and NF-κB p50 as key early regulators of both IL-6 and IFN-β gene expression in CAL-1 cells. Proximity ligation assays (PLAs) demonstrated PtdIns(3,4)P2 that IRF-5 and NF-κB p50 but not p65 significantly co-localized within the nucleus of these cells within 30

min of stimulation, consistent with these factors cooperatively mediating gene expression. In contrast to data derived from murine studies, IRF-8 was identified as a negative regulator of IFN-β and IL-6 expression, indicating that IRF-5 and IRF-8 compete to control gene expression following “K” ODN stimulation in human pDCs. This work also demonstrates that endogenous IRF-5 and IRF-7 are associated with MyD88 in resting CAL-1 cells but stimulation with “K” ODN leads to the activation only of IRF-5. As IRF-5 and IRF-8 variants are associated with autoimmune diseases such as lupus [23-28], these findings are relevant to our understanding of the pharmacologic effects of “K” ODN and the role of TLR9 ligation under physiologic, pathologic, and therapeutic conditions. CAL-1 cells share many phenotypic and functional properties of human pDCs [12, 21, 22].

Eighty isolates originating from 71 patients comprised 50 (62.5%) from pulmonary cases, 15 (19%) from rhino-orbital-cerebral, 13 (16.2%) from cutaneous and 2 (2.5%) from disseminated mucormycosis. ITS and D1/D2 regions sequencing of the isolates identified, Rhizopus arrhizus var. delemar (n = 25), R. arrhizus var. arrhizus (n = 15), R. microsporus (n = 17), R. stolonifer (n = 3), Syncephalastrum racemosum (n = 11), Apophysomyces Acalabrutinib elegans (n = 2), A. variabilis (n = 2), Lichtheimia ramosa (n = 3)

and Mucor circinelloides f. lusitanicus (n = 2). Amplified fragment length polymorphism analysis was done to genotype Rhizopus isolates and revealed 5 clusters of R. arrhizus, which were well separated from R. microsporus. Amphotericin B was the most potent antifungal followed by posaconazole, itraconazole and isavuconazole. Etest BMN 673 in vitro and CLSI MICs of amphotericin B showed 87% agreement. Overall, the commonest underlying

condition was uncontrolled diabetes mellitus. Records of 54 patients revealed fatalities in 28 cases. Mucormycosis is a highly aggressive fungal infection caused by members of the order mucorales.[1] The incidence of disease caused by mucoralean fungi is increasing, especially in hosts with immune or metabolic impairment, e.g. in patients with uncontrolled diabetes mellitus, haematological malignancies and haematopoietic stem cell transplant.[2-7] Although the majority of infections are caused by species of the genus Rhizopus, other frequently reported genera include Mucor, Lichtheimia, Rhizomucor, Apophysomyces, Cunninghamella, Saksenaea and Syncephalastrum.[5, 8] The species of mucormycetes show significant differences in susceptibility to amphotericin

B, posaconazole, itraconazole, voriconazole and terbinafine.[9-14] Of these amphotericin B lipid formulations remain the mainstay of treatment, whereas posaconazole has been successfully used as salvage therapy.[15-17] Furthermore, the identification of the species of the mucoralean fungi are relevant for studying the epidemiology of mucormycosis in different geographical areas, especially in India, where different risk factors and aetiologic agents as compared to several other countries have been reported.[5] The routine Fludarabine price microbiology laboratories generally report the etiologic agent as zygomycete or rarely identify them up to genus level due to lack of classical mycological expertise. In the recent past sequencing of the internal transcribed-spacer (ITS) region has emerged as a reliable tool for the identification of this fungal group at a species level and could be used for DNA barcoding.[11, 18-21] So far only a few comprehensive studies using this tool had molecularly characterised clinically important mucorales and explored the possibility of specific antifungal susceptibility profiles linked to a particular phylogenetic taxon of mucorales.

Results: Despite extensive investigations for bleeding, haematuria, haemoptysis, peritoneal bleeding and rectal bleeding, the only abnormalities found are thin GBM and a small rectal polyp. Conclusions: We believe this patient presents with unusual manifestations of bleeding secondary to a genetic defect in type IV collagen. check details 293 RENO NEURO CARDIO SYNDROME – FABRY’S DISEASE: A CASE REPORT JS JAMBOTI1, CH FORREST2 1Department of Renal Medicine, Fremantle Hospital, Fremantle, Western Australia;

2Path West Laboratory Medicine, Fremantle Hospital, Fremantle, Western Australia, Australia Background: Fabry’s disease is a rare X-linked recessive disorder resulting in low levels or absent Lysosomal enzyme

Alpha Galactosidase (AGAL) resulting in build up of Globotriaosylceramide in the cells of various organs like kidneys, CNS and heart leading to protean manifestations. Glomerular injury leads to Focal Segmental Glomerulosclerosis (FSGS). Diagnosis is established by low leucocyte AGAL levels. Electron Microscopy (EM) of renal biopsy selleck products reveals characteristic diagnostic findings. Case Report: A 21 year old man was referred in 2001 with peripheral oedema and a family history of “nephritis” in his deceased grandfather. Serum creatinine was 150 μmol/L and urinary protein 1.5 g/24 h. Renal biopsy

revealed FSGS. Arterio venous fistula was created in March 2011 with stage 4 CKD. Two months later the patient developed Status Epilepticus. MRI revealed multi focal, bi-hemispherical White Matter Lesions. Brain biopsy was performed and patient treated with a diagnosis of Primary CNS Vasculitis. Patient was found to have severe LVH on ECG during the work up for renal transplantation. Dobutamine stress echocardiogram revealed dynamic left ventricular outflow obstruction. Retinal vein branch occlusion was also detected. With multi-system involvement and positive family history, Fabry’s disease was suspected. Low Leucocyte AGAL levels (0.2 nmol/min/mg protein [normal 0.7–3.3]) confirmed the diagnosis. The initial renal biopsy was reviewed with EM at this point, which revealed the characteristic laminated lipid deposits in endothelial cells and macrophages. Discussion and Conclusions: The GNE-0877 diagnosis of Fabry’s disease is often delayed by a decade or more from the initial presentation. Early diagnosis and Enzyme Replacement Therapy might limit the severity of the disease manifestations with improved outcomes. Awareness of the condition and importance of EM in establishing the diagnosis are highlighted. 294 THE EFFECT OF RITUXIMAB IN ADULTS WITH STEROID-DEPENDENT MINIMAL CHANGE DISEASE M LEE, K NICHOLLS Royal Melbourne Hospital, Melbourne, Victoria, Australia Background: Minimal Change Disease (MCD) commonly presents as idiopathic nephrotic syndrome in children.

Judging from these reports,

the neutrophil recruitment essential for the elimination of A. baumannii may be induced by Th1-type immune responses, and these Th1-type cytokines may be secreted by NK1.1+ cells. NKT cells can make both the FK228 chemical structure Th1-type cytokine IFN-γ and the Th2-type cytokines IL-4 and IL-13. These cells appear to play an important role in allergy, autoimmunity, and tumor control. Moreover, NKT cells play an important protective role in bacterial infection (19, 20). However, Bourgeois et al. reported that NKT cells suppressed neutrophil migration into the lung via Th1-type cytokines IFN-γ and IL-12 (41).It is necessary to clarify whether NK cells or NKT cells are important in the migration DMXAA ic50 of neutrophils. IL-17A is thought to participate in host defense against various pathogens and induce the production of TNF-α and CXC chemokines in the lung (42–45). In the present study, the expression level of IL-17A increased in lung tissues at 1 day after inoculation of A. baumannii, and up-regulation of IL-17A was delayed by anti-NK1.1 Ab treatment (data not shown). IL-17A and IL-17F may increase the expression level of neutrophil chemotactic factors, including KC (in mouse), MIP-2 (in mouse

and humans), and IL-8 (in humans) and may be driven by lung epithelial cells (46). Also, the IL-17A-producing cells in bacterially infected lungs appear to be γδT cells rather than CD4+ Th17 cells (47–49). In the present study, γδT cells were detected in the lungs of mice with Acinetobacter pneumonia, and their numbers rapidly (-)-p-Bromotetramisole Oxalate increased up until Day 3 post-inoculation (data not shown). Thus, γδT cells may be involved in neutrophil recruitment and

may directly or indirectly interact with NK1.1+ cells. The detailed molecular mechanisms underlying the role of γδT cells on Acinetobacter pneumonia remain to be elucidated. In conclusion, the results of the present study show that NK1.1+ cells induce neutrophil recruitment by increasing the expression levels of KC during the early phase of Acinetobacter infection. Further understanding of the molecular mechanisms underlying NK1.1+ cell-mediated immune regulation may lead to improved control of A. baumannii infections.

“Janus kinase (JAK) inhibitors have been developed as anti-inflammatory agents and have demonstrated clinical efficacy in rheumatoid arthritis (RA). We investigated if JAK-3-selective inhibition alone could disrupt cytokine signalling in rheumatoid synovial fibroblasts.

Limited studies have demonstrated that the expression of all KIRs without distinguishing activating or inhibitory receptors was elevated on CD8+T cells in asymptomatic HIV infection, predominantly on memory CD8+ T cells, associated with a reduced ability

Ceritinib cell line to kill target cells (19–21). However, expression of the main KIR receptor, KIR3DL1, and the extent of KIR-induced dysregulation at different stages of HIV infection remain poorly understood. Previous studies focused on the expression of a single NKR. However, the expression of a given NKR, such as NKG2D, may be associated with the expression of other NKRs, as in the case of NKG2D+NKG2A−, NKG2D+NKG2A+, NKG2D+KIR3DL1−, and NKG2D+KIR3DL1+. Thus, combinational analysis may offer a clearer description of the status of T cell function than analysis of an individual NKR. Here, we characterized the changes of NKG2D, NKG2A, and KIR3DL1 on CD8+ and CD3+ CD8− cells by both individual and combinational analysis of receptor expression in patients at different stages of HIV infection. Forty-five HIV-positive patients were recruited at the Red Ribbon outpatient clinic of China Medical University’s

Sunitinib AIDS Research Center in Shenyang, Liaoning province, China. HIV infection was diagnosed by positive anti-HIV enzyme-linked immunosorbent assay (ELISA; Vironostika, Organon Teknika, The Netherlands) and confirmed by a positive Western immunoblot (Gene Lab Diagnostics, Singapore). These individuals were then stratified by CD4+ T cell counts. Patients with CD4+ T cell

counts >200 cells/μL and no HIV symptoms were defined as treatment-naïve, chronically HIV-infected patients. Meanwhile, patients with CD4+ T cell counts <200 cells/μL or with indications of AIDS were categorized as treatment-naïve AIDS patients. According to these criteria, 23 treatment-naïve, chronically HIV-infected patients were enrolled in the study, constituting the HIV group. below These patients had median CD4+ T cell counts of 492 cells/μL (range 228 cells/μL to 968 cells/μL) and a median viral load of 19 400 copies/mL (range <400 copies/mL to 494 000 copies/mL). Ten treatment-naïve AIDS patients were enrolled and placed in the AIDS group; these patients had median CD4+ T cell counts of 178 cells/μL (range 15 cells/μL to 299 cells/μL) and a median viral load of 39 300 copies/mL (range 15 900 copies/mL to 1 050 000 copies/mL). Twelve AIDS patients undergoing HAART treatment were also asked to participate in the study and were placed into the HAART group. All patients in this group had received rigorous HAART treatment for at least one year and had undetectable levels of HIV RNA, median CD4+ T cell counts of 414 cells/μL (range 258 cells/μL to 942 cells/μL), and undetectable viral loads (<400 copies/mL). Finally, 17 HIV-negative normal individuals were randomly selected from the general population and placed into the HIV-negative normal control group.

Vetrano (Rozzano) who had studied colonic sections from patients suffering from inflammatory bowel disease. S. Vetrano had also generated PC–/– transgenic mice, which were found to develop spontaneous intestinal inflammation and severe colitis, along with decreased expression of JAM-A, claudin-3 and alterations

in ZO-1 expression. A joint session held in collaboration with the Italian Society for Rheumatology hosted different talks. The effects TNF-α-blocking agents on monocytes and T cells in rheumatoid arthritis (U. Wagner, Leipzig), the role of biological drugs in the treatment of ANCA-associated systemic vasculitis (R. A. Sinico, Milan), as well as novel pathways and possible new targets in SLE (F. R. Spinelli, Rome), were all discussed. In the afternoon, talks were given by M. Cassatella (Verona) who reviewed the ability of neutrophils to undertake bidirectional learn more cross talks with different cell types, including DCs, NK, iNKT and also unpolarized T cells. T. Laskay (Lübeck) showed that intracellular pathogens can globally diminish the expression of IFN-γ-regulated genes. The development of the thymus during evolution and, in particular, its phylogenetic

pendant in jawless vertebrates (agnathans) was discussed by T. Boehm (Freiburg), while L. Screpanti (Rome) presented data on the relative contributions and interconnectivity of Notch3, the pre-TCR and NF-kB in the development of T cells. A. Diefenbach (Freiburg) reported that dietary AhR ligands dynamically regulated postnatal development of lymphoid follicles by controlling the pool size of LTI-like ILCs. Concerning tumor

immunology, Panobinostat T. Blankenstein (Berlin) reported an aberrant rather than protective T-cell response, resulting in tolerance at the premalignant stage, while P. Yu (Marburg) showed that TLR-3, -7 and -9 can protect against murine T-cell lymphomas caused by endogenous retroviruses. The role of protein kinase CK2 as a pro-survival molecule that protects multiple myeloma cells from bortezomib, the first therapeutic proteasome inhibitor, was discussed by F. Cinetto (Padova). In the late afternoon, after viewing and discussing more than 300 posters and attending BCKDHA several workshops, members participated in the Assembly of their respective Society, both meetings being characterized by a very relaxed atmosphere (p<0.000001 versus several other assemblies that we have attended). The new SIICA board with Prof. V. Barnaba (Rome) as the new President was elected during the SIICA Assembly. Finally, one of the most exciting moments of the meeting arrived. If you put together any number of randomly selected Italians and Germans aged 4 years or older, you can be sure that after a couple of nanoseconds a challenging discussion starts about who are, or who were, the best football (or soccer, for readers in the new world) players, trainers, or national teams.
