e., absence of deafferentation), RA (i.e., deafferentation), and vision (i.e., deafferentated limb exposed to view). To limit potential bias such as order effect, the control state was recorded in a randomized manner.\n\nResults: All subjects described perceptual illusions of their anesthetized limb. They were slower and less accurate on the task during RA compared with control. Response patterns were similar SNX-5422 in all conditions, suggesting sensitivity of performance to arm/hand biomechanical constraints. Vision

was associated with an increase in the proportion of correct responses and a reduction of the response times in hand judgment and was accompanied by disappearance of the lateralization of the underlying

mental representations, which was identified during RA.\n\nConclusions: These results suggest the following: (1) the right/left judgment task involves mental simulation of hand movements, (2) underlying mental representations and their neural substrates are subject to acute alterations after RA, and (3) the proprioceptive deficit induced by RA is influenced by the subject’s ability to see the anesthetized limb.”
“Objectives: We developed minimal incision-assisted retroperitoneoscopic DZNeP cost surgery (MARP) in an attempt to pursue optimized patient-related benefits. We evaluated the clinical value of MARP for upper urinary tract diseases compared with pure retroperitoneoscopic surgery (PRPS).\n\nPatients and Methods: Between January 2003 and September 2008, PRPS and MARP were carried out in 338 and 85 patients, respectively. The upper urinary tract surgical procedures were defined as simple and complex procedures. We defined our experience from January 2003 to December 2005 as our early stage of PRPS learning curve. Linsitinib datasheet Our experience from January 2006 to September 2008 was defined as our late stage

of PRPS learning curve. Patients’ perioperative details were compared.\n\nResults: MARP was associated with shorter operative time for each complex procedure and with less frequent conversion to open surgery (2.4% vs. 11.3%, p – 0.023). A significantly greater proportion of MARP patients underwent complex procedures (81.2% vs. 49.1%, p < 0.001), and a significantly greater proportion of MARP were carried out at the early stage of PRPS learning curve (62.4% vs. 44.1%, p = 0.003). Estimated blood loss, hospital stay, the amount of analgesic use (diclofenac sodium suppository), and intraoperative and postoperative complications were comparable.\n\nConclusions: MARP maintains the patient-related benefits of PRPS while allowing surgeons to perform more complex cases of upper urinary tract diseases and shortening the relevant operative time. It can be useful for cases in which the specimen is going to be extracted intact, when starting out learning retroperitoneoscopy, or when unable to progress the case using laparoscopic techniques.

\n\nConclusions: Information on indications and dosages were usually provided by pharmaceutical

representatives in Australia and Malaysia. However, risk and harmful effects of medicines were often missing in their presentations. Effective control of medicines information provided by pharmaceutical representatives is needed.”
“AIM: Our study focuses on the approach, management and treatment of patients with polythelia and supernumerary breast and the target is the search for a treatment algorithm for these diseases.\n\nMATERIAL OF STUDY: We considered at 18 patients treated from 2006 to 2011 for breast congenital anomalies in excess. 14 surgical procedures were performed, 8 for supernumerary nipple excision (1 case associated with Poland Syndrome) and 6 for accessory breast ablation. All patients were aged between 15 and 34 years and belonged to both sexes.\n\nRESULTS: The breast tissue it was detected fibrocystic LY-374973 mastopathy in 5 cases of polimastia. In the remaining cases the nipples and mammary tissues were normal. After a median follow-up from one to five years, we obtained in all cases not only an excellent aesthetic result but also a psychological.\n\nDISCUSSION: The supernumerary breast tissue is not just a cosmetic problem, it is also subject to the same pathological lesions that are observed in a normal breast. In view

of thepotential malignant transformation of anomalous breast incidentally, early selleck and accurate diagnosis is required as well as its monitoring over time.\n\nCONCLUSIONS. We therefore believe that surgical approach is always necessary in cases of polimastia, while considering options in the treatment of polythelia, where it becomes crucial if aesthetic and/or psychologically problems in the patient coexist.”
“Neurons have highly polarized arrangements of microtubules, CYT387 supplier but

it is incompletely understood how microtubule polarity is controlled in either axons or dendrites. To explore whether microtubule nucleation by gamma-tubulin might contribute to polarity, we analyzed neuronal microtubules in Drosophila containing gain-or loss-of-function alleles of gamma-tubulin. Both increased and decreased activity of gamma-tubulin, the core microtubule nucleation protein, altered microtubule polarity in axons and dendrites, suggesting a close link between regulation of nucleation and polarity. To test whether nucleation might locally regulate polarity in axons and dendrites, we examined the distribution of gamma-tubulin. Consistent with local nucleation, tagged and endogenous gamma-tubulins were found in specific positions in dendrites and axons. Because the Golgi complex can house nucleation sites, we explored whether microtubule nucleation might occur at dendritic Golgi outposts. However, distinct Golgi outposts were not present in all dendrites that required regulated nucleation for polarity.

27 (0.24-0.30) versus 0.40 (0.35-0.44) (p smaller than 0.001). Conservative oxygen therapy decreased the median total amount of oxygen delivered during mechanical ventilation by about two thirds (15,580 L [8,263-29,351 L] vs 5,122 L [1,837-10,499 L]; p smaller than 0.001). The evolution of the Pao(2)/Fio(2) ratio was similar MAPK Inhibitor Library cell line during the two periods, and there were no difference in any other biochemical or clinical outcomes. Conclusions: Conservative oxygen therapy in mechanically ventilated ICU patients was feasible and free of adverse biochemical, physiological, or clinical outcomes while allowing a marked

decrease in excess oxygen exposure. Our study supports the safety and feasibility of future pilot randomized controlled trials of conventional compared with conservative oxygen therapy.”
“The red cusk-eel (Genypterus

chilensis) is an endemic fish species distributed along the coasts of the Eastern South Pacific. Biological studies on this fish are scarce, and genomic information for G. chilensis is practically nonexistent Thus, transcriptome information for this species is an essential resource that will greatly enrich molecular information and benefit future studies of red cusk-eel biology. In this work, we obtained transcriptome information of G. chilensis using the Illumina platform. The RNA sequencing generated 66,307,362 and 59,925,554 paired-end selleck compound reads from skeletal muscle and liver tissues, respectively.

De novo assembly using the CLC Genomic Workbench version 7.0.3 produced 48,480 contigs and created a reference transcriptome with a N50 of 846 bp and average read coverage of 28.3x. By sequence similarity search for known proteins, a total of 21,272 (43.9%) contigs were annotated for their function. Out of these annotated contigs, 335% GO annotation results for biological processes, 32.6% GO annotation results for cellular components and 34.5% GO annotation results for molecular functions. This dataset represents the first transcriptomic resource for the red cusk-eel and for a member of the Ophidiimorpharia taxon. (C) 2014 Elsevier B.V. All rights reserved.”
“In SBE-β-CD supplier this work four cationic additives were used to improve the surface activity of lung surfactants, particularly in the presence of bovine serum that was used as a model surfactant inhibitor. Two of those additives were chitosan in its soluble hydrochloride form with average molecular weights of 113 kDa and 213 kDa. The other two additives were cationic peptides, polylysine 50kDa and polymyxin B. These additives were added to bovine lipid extract surfactant (BLES) and the optimal additive-surfactant ratio was determined based on the minimum surface tension upon dynamic compression, carried out in a constrained sessile drop (CSD) device in the presence of 50 mu l/ml serum. At the optimal ratio all the BLES-additive mixtures were able to achieve desirable minimum surface tensions.

In the amygdala, subsequent ontological analyses using the GOMiner algorithm demonstrated significant enrichment in categories related to cytoskeletal reorganization and cation transport, as well as in gene families related to synaptic transmission and neurogenesis. In the hippocampus, significant enrichment in gene expression within categories related to cytoskeletal reorganization and cation transport was similarly observed. Furthermore, unique to the hippocampus, enrichment in transcription factor activity and GTPase-mediated signal transduction was identified. Overall, these data identify specific and unique neurochemical pathways chronically altered following VX-809 inhibitor kindling in

the two sites, and provide a platform for defining the molecular basis for the differential behaviors observed in the interictal period.”
“Gamma-melanocyte stimulating hormone (gamma-MSH) is a peptide derived from the ACTH precursor, proopiomelanocortin (POMC), and belongs to a family of peptides called the melanocortins that also comprises alpha- and beta-MSH. Although conserved in tetrapods, the biological role of gamma-MSH remains largely undefined. It has been demonstrated previously that gamma-MSH is involved in the regulating the activity of hormone sensitive lipase (HSL) activity in the adrenal and more recently, in the adipocyte. It has been shown also to have effects on the cardiovascular and renal systems.\n\nThis short review will provide a

brief overview of the role of gamma-MSH in the adrenal and the more recent report that it can also regulate HSL function in the adipocyte. We also present some preliminary data purporting a direct role for Lys-gamma(3)-MSH find more in the regulation of HSL phosphorylation in the heart. Taken together these data suggest that gamma-MSH peptides might play a more widespread role in lipid and cholesterol utilization. (C) 2008 Elsevier Ireland Ltd. All rights reserved.”
“Background: Although there are increasing numbers of long-term survivors

on dialysis, there is remarkably little information about their medical and social wellbeing. Methods: A group of 46 current survivors of long-term dialysis at a single centre were identified and asked to complete a structured interview; selected routine blood tests were also reviewed. The group’s background and renal replacement history PP2 cost are described, along with frequencies of various complications. Results: Younger age and non-diabetic renal disease are associated with longer survival. Substantial morbidity accumulated over the time on dialysis, particularly vascular disease ( 57%) which was strongly linked to smoking history, as well as musculoskeletal complications ( 78%) and nutritional decline ( 80%). Encapsulating peritoneal sclerosis developed in 4 patients, after between 9 and 13 years of peritoneal dialysis. Conclusions: Despite accumulating morbidity, a surprisingly stable and socially well- adjusted group is revealed, with low rates of hospital admission in the majority.

\n\nRESULTS: Forty patients were evaluated. Visual analog scale values with dexmedetomidine were significantly lower than those with propofol only at the 25-35

min assessments (P < 0.05). During sedation, the respiratory rate with dexmedetomidine was significantly slower but Spo(2) was significantly higher than with propofol (P < 0.05). Other clinical variables were similar (P > 0.05).\n\nCONCLUSION: A combination of dexmedetomidine with fentanyl can be used safely and effectively for sedation and analgesia during ESWL.”
“The binding between the estrogen receptor alpha (ER-alpha) and a variety of compounds in traditional Chinese formulae, Si-Wu-Tang (SWT) series decoctions, was studied using a stably-transfected human EVP4593 clinical trial breast cancer cell line (MVLN). In 38 compounds tested from SWT series decoctions, the estrogen-like click here activity of 22 compounds was above 60% in 20 mu gmL (1). Furthermore, theoretical affinity of these compounds was certificated using the functional virtual screen of ER-alpha modulators by FlexX-Pharm.

The accuracy of functional virtual screening of ER-alpha modulators could reach to 77.27%. The results showed that some compounds, such as organic acids and flavones in SWT series decoctions could be used as selective estrogen receptor modulators (SERMs) and could be selected for further development as potential agents for estrogen related diseases.

“Carney complex (CNC) is LY333531 an autosomal dominant neoplasia syndrome caused by inactivating mutations in PRKAR1A, the gene encoding the type 1A regulatory subunit of protein kinase A (PKA). This genetic defect induces skin pigmentation, endocrine tumors, myxomas, and schwannomas. Some patients with the complex also develop myxoid bone tumors termed osteochondromyxomas. To study the link between the PRKAR1A mutations and tumor formation, we generated a mouse model of this condition.

Prkar1a(+/)-mice develop bone tumors with high frequency, although these lesions have not yet been characterized, either from human patients or from mice. Bone tumors from Prkar1a(+/)-mice were heterogeneous, including elements of myxomatous, cartilaginous, and bony differentiation that effaced the normal bone architecture. Immunohistochemical analysis identified an osteoblastic origin for the abnormal cells associated with islands of bone. To better understand these cells at the biochemical level, we isolated primary cultures of tumoral bone and compared them with cultures of bone from wild-type animals. The tumor cells exhibited the expected decrease in Prkar1a protein and exhibited increased PKA activity. At the phenotypic level, we observed that tumor cells behaved as incompletely differentiated osteoblasts and were able to form tumors in immunocompromised mice.

Abuse of 3,4-DMMC is widespread and a Milciclib chemical structure global issue. However, to date, there have been no reports of 3,4-DMMC-related deaths. We encountered a death in which 3,4-DMMC was thought to play a causative role, and successfully identified this designer drug from biological samples by using LC-MS/MS and QuEChERS (quick, easy, cheap, effective, rugged and safe) extraction

method. For standard samples, detection of 3,4-DMMC in human blood and urine samples in the calibration range (5-400 ng/ mL) was successful with recoveries of 85.9-89.4% (blood) and 95.8-101% (urine), limits of detection of 1.03 (blood) and 1.37 ng/mL (urine) and limits of quantification of 5.00 (blood) and 5.38 ng/mL (urine). The concentrations of 3,4-DMMC in blood (external iliac vein) and urine in the case were 27 mg/L and 7.6 mg/L, respectively. Some metabolites, including 3,4-dimethylcathione (DMC) and beta-ketone reduced metabolites Ulixertinib concentration (p-OH-DMMC and 13-0H-DMC), were detected in both blood and urine.

“Monocyte development is a tightly regulated and multi-staged process, occurring through several defined progenitor cell intermediates. The key transcription factors, including PU.1, IRF8 and KLF4, growth factors, such as M-CSF and IL-34 and cytokines that drive monocyte development from hematopoietic progenitor

cells are well defined. However, the molecular controls that direct differentiation into the Ly6C(hi) inflammatory and Ly6C(lo) monocyte subsets are yet to be completely elucidated. This review will provide a summary of the transcriptional regulation of

monocyte development. We will also discuss how these molecular controls are also critical for microglial development despite their distinct Fer-1 haematopoetic origins. Furthermore, we will examine recent breakthroughs in defining mechanisms that promote differentiation of specific monocyte subpopulations. (C) 2014 Elsevier Inc. All rights reserved.”
“Cellulose has been demonstrated to be dissolved in 7 wt% NaOH/12 wt% urea aqueous solution pre-cooled to -12 degrees C, as a result of the formation of inclusion complexes (ICs) associated with cellulose, urea and NaOH. However, this cellulose solution is meta-stable, and IC aggregate could form. In this work, the influences of solvent composition and temperature on the stability of the cellulose ICs in NaOH/urea aqueous solvent system were investigated by dynamic and static light scattering. The stability of cellulose ICs in NaOH/urea aqueous solvent system was firstly enhanced and then lessened with NaOH concentration increasing. The addition of urea slightly enhanced the stability of ICs. Furthermore, the solvent composition had been optimized to reduce the aggregation phenomenon of ICs. The proportion of single cellulose ICs in 9 wt% NaOH/13 wt% urea system increased to 0.96, indicating a stable and better dispersion system of the cellulose ICs.

\n\nOur results showed the interaction of WGA with two porphyrin compounds – Fe porphyrin and Pd porphyrin. The dissociation constants for the porphyrin binding was kD (0.08-1.02 mu M) showing high affinity for the two Z-VAD-FMK inhibitor porphyrins for this protein. The hyperbolic titration curve indicated the presence of a single porphyrin binding site.\n\nIn conclusion, we show that two photosentisizers with anticancer activity Fe porphyrin and Pd porphyrin, have high affinity for WGA. Since WGA binds to cancer cells,

the results suggest that it may have utility in the targeted delivery of drugs for cancer Biotechnol. & Biotechnol. Eq. 2011, 25(3), 2519-2521″
“Background: There arc 50,000 practitioners of complementary and alternative medicine (CAM) within the United Kingdom. The current U.K. prevalence of CAM use is reported to be 25% and is rising. The national expenditure on CAM is an estimated 1.6 billion. The aim of this study was to explore the pattern of CAM use in patients attending Kinesin inhibitor a rhinology outpatient clinic in Aberdeen.\n\nMethods: Questionnaires were provided to 100 patients over a 2-month period. The questionnaire consisted of demographic sections and whether they had ever used CAM from a list of 49 herbal and nonherbal alternative therapies. Subjects were also asked why they used CAM, where they learned of

CAM, whether they found it efficacious, and whether their general practitioner was aware they were using it.\n\nResults: One hundred subjects completed question noires. Patients attending the clinic were suffering from the most common rhinological complaints including rhinosinusitis and nasal polyps. Sixty-five percent of patients had ever used CAM. Women were statistically significantly more likely to use CAM than men (p = 0.012). Patients who were employed were more likely Vorinostat to use CAM, but there ZOOS 110 significant difference in CAM usage depending on marital status, social class, and age. Only 6% of patients felt CAM use was definitely ineffective.

Only 43% of users of CAM had informed their doctor about its use.\n\nConclusion: CAM usage is growing in popularity. All health care professionals should be aware of this and of the potential for adverse drug reactions occurring. The dangers of noncompliance with conventional medications should be emphasized to CAM users.”
“Metazoan tissues have the ability to maintain tissue size and morphology while eliminating aberrant or damaged cells. In the tissue homeostasis system, cell division is the primary strategy cells use not only to increase tissue size during development but also to compensate for cell loss in tissue repair. Recent studies in Drosophila, however, have shown that cells in postmitotic tissues undergo hypertrophic growth without division, contributing to tissue repair as well as organ development. Indeed, similar compensatory cellular hypertrophy (CCH) can be observed in different contexts such as mammalian hepatocytes or corneal endothelial cells.

Yet, these compounds largely retain their inhibitory activity for bacterial ribosomes and show antibacterial activity. Our data indicate that 4′-O-substituted aminoglycosides possess increased selectivity towards bacterial ribosomes and little activity for any of the human drug-binding pockets.”
“Aims: To test the hypothesis that cumulative exposure to insulin and long-acting insulin analogs might be associated with cancer mortality in diabetes patients. Methods: All consecutive diabetes patients aged over 40 Milciclib cost years, residing in a major urban area were screened at

their first diabetes outpatient visit between 01/01/2001-12/31/2008 (n = 79869). Exclusion criteria were insulin treatment at screening, no insulin treatment until 12/31/2008, less than 6 months of glucose-lowering

treatment alone before insulin initiation, insulin prescription before glargine became available, age smaller than 40/ bigger than = 80 years at first insulin prescription, and smaller than 6 months of insulin exposure. A total 4990 subjects were followed-up for death based on death certificate, until 12/31/2011. Adjusted time-dependent competing risk regression analysis, with daily updates of treatment modalities was performed. Results are expressed for every 10,000 IU of cumulative dose or one year of cumulative time exposure to insulin. Results: Mean baseline age was 62 +/- 9 years, and follow-up 4.7 +/- 1.9 years. Glargine cumulative dose was associated with Ulixertinib cell line lower cancer mortality risk (subhazard ratio, SHR: 0.94 (95%CI 0.89-0.99, p = 0.033)). Cumulative exposure limited to that attained one year prior to death revealed lower SHRs

for cumulative Fer-1 datasheet time (0.94 (95%CI 0.89-0.99, p = 0.018)) and cumulative dose of glargine (0.92 (95%CI 0.86-0.98, p = 0.014)). Glargine cumulative time and cumulative dose were significant predictors for lower pancreatic and breast cancer mortality, but not for deaths from lung, colorectal, female genital, liver, and urinary tract cancer. No increased hazards were found for any other subtypes of insulins. Conclusions: The cumulative dose exposure to insulin glargine was associated with a lower risk of cancer mortality in general, and of breast and pancreatic cancer in particular. This effect remained even after additional “fixed” cohort or propensity score analyses.”
“Background and aims Golgi protein 73 (GP73) as a potential serum marker for hepatocellular carcinoma (HCC) has not been validated in large cohort studies. Furthermore, its significance in the assessment of tumour recurrence after HCC resection remains unknown. The aim of this study was to determine the value of serum GP73 in the diagnosis of HCC.

\n\nRESULTS: We identified 894 inpatients with incident CDI. The cumulative incidence of CDI recurrence in the cohort was 23%. Receipt of PPIs concurrent with CDI treatment was not associated with C. difficile recurrence (hazard ratio (HR)=0.82; 95% confidence interval (CI)=0.58-1.16). Black race (HR=1.66, 95% CI=1.05-2.63), increased age (HR=1.02, 95% CI=1.01-1.03), and increased comorbidities (HR=1.09, 95% CI=1.04-1.14) were associated with CDI recurrence. In light of a higher 90-day mortality

Dinaciclib clinical trial seen among those who received PPIs (log-rank P=0.02), we also analyzed the subset of patients who survived to 90 days of follow-up. Again, there was no association between PPIs and CDI recurrence (HR=0.87; 95% CI=0.60-1.28). Finally, there was

no association between recurrent CDI and increased duration or dose of PPIs.\n\nCONCLUSIONS: Among hospitalized adults with C. difficile, receipt of PPIs concurrent with C. difficile treatment was not associated with CDI recurrence. Black race, increased age, and increased comorbidities AZD2014 cell line significantly predicted recurrence. Future studies should test interventions to prevent CDI recurrence among high-risk inpatients.”
“OBJECTIVES The major aim of this study is to test the hypothesis that stress cardiac magnetic resonance (CMR) imaging can provide robust prognostic value in women presenting with suspected ischemia, to the same extent as in men.\n\nBACKGROUND Compelling evidence indicates that women with coronary artery disease (CAD) experience worse outcomes than men owing to a lack of early diagnosis and management. Numerous clinical studies have

shown that stress CMR detects evidence of myocardial ischemia and infarction at high accuracy. Compared to nuclear scintigraphy, CMR is free of ionizing radiation, has high spatial resolution for imaging small hearts, and overcomes breast attenuation artifacts, which are substantial advantages when imaging women for CAD.\n\nMETHODS We performed stress CMR in 405 patients (168 women, mean age 58 +/- 14 years) referred for ischemia assessment. CMR techniques GW3965 ic50 included cine cardiac function, perfusion imaging during vasodilating stress, and late gadolinium enhancement imaging. All patients were followed for major adverse cardiac events (MACE).\n\nRESULTS At a median follow-up of 30 months, MACE occurred in 36 patients (9%) including 21 cardiac deaths and 15 acute myocardial infarctions. In women, CMR evidence of ischemia (ISCHEMIA) demonstrated strong association with MACE (unadjusted hazard ratio: 49.9, p < 0.0001). While women with ISCHEMIA(+) had an annual MACE rate of 15%, women with ISCHEMIA(-) had very low annual MACE rate (0.3%), which was not statistically different from the low annual MACE rate in men with ISCHEMIA(-) (1.1%).

A systems biology analysis of HDL protein alterations induced by PTCA revealed an increase in two protein clusters that included several apolipoproteins, fibrinogen-like protein 1 and other intracellular proteins, and a decrease in antithrombin-III, LCL161 manufacturer annexin A1 and several immunoglobulins. Our results support the concept of HDL as dynamic platforms that donate and receive a variety of molecules and provide an improved methodology

to use HDL proteome for the systematic analysis of differences among individuals and the search for cardiovascular biomarkers. Biological significance The HDL proteome is an interesting model of clinical relevance and has been previously described to be dynamically altered in response to pathophysiological conditions and cardiovascular diseases. Our study suggests that interindividual variability of HDL proteome is higher than previously thought and provided the detection of a set of proteins that changed their abundance in response to plaque rupture, supporting

the concept of HDL as dynamic platforms that donate and receive a variety of molecules. (C) 2014 Elsevier B.V. All rights reserved.”
“A precursor of miR156 (MsmiR156d) was cloned and overexpressed in alfalfa (Medicago sativa L.) as a means to enhance alfalfa biomass yield. Of the five predicted SPL genes encoded by the alfalfa genome, three (SPL6, SPL12 and SPL13) contain miR156 cleavage sites and their expression was down-regulated in transgenic alfalfa plants overexpressing miR156. These transgenic plants had reduced internode length and stem

thickness, enhanced shoot BVD-523 price branching, increased trichome density, a delay in flowering time and elevated biomass production. Minor effects on sugar, starch, lignin and cellulose contents were also observed. Moreover, transgenic alfalfa plants had increased root length, while nodulation was maintained. The multitude of traits affected by miR156 may be due to the network of genes regulated by the three target SPLs. Our results show that the miR156/SPL system has strong potential as a tool to substantially improve quality and yield traits in alfalfa.”
“Distinguishing chondrosarcoma from chondroblastic osteosarcoma can be difficult and highly subjective, especially on a small biopsy CA3 in vivo specimen. This distinction is critical in determining the most accurate prognosis and appropriate treatment modality, as adjuvant chemotherapy with surgery is standard treatment for osteosarcoma, whereas chondrosarcoma is generally treated by surgical excision alone. Cartilaginous neoplasms have recently been shown to frequently (56%) harbor gene mutations in the metabolic enzymes isocitrate dehydrogenase 1 (IDH1) and IDH2 (IDH1 > IDH2), whereas other mesenchymal tumors lack these genetic aberrations. We investigated whether the presence of IDH1/2 mutations can be used to distinguish chondrosarcoma from chondroblastic osteosarcoma.
