URu2Si2 presents superconductivity at temperatures below 1.5 K and a hidden order (HO) at about 17.5 K. Both electronic phenomena are influenced by fano and kondo resonances. At 17.5 K the HO was related in the past to a peierls distortion that produces an energy gap deformed by the resonances. This order has been studied for more than 20 years and still there is no clear understanding. In this work we studied the electronic characteristics of uru2si2 in a single crystal, with tunneling and metallic point contact spectroscopies.Preparacion para radiografia de columna lumbosacra sanitas


in the superconducting state, we determined the energy gap, which shows the influence of the fano and kondo resonances. At temperatures where HO is observed, the tunnel junctions spectra show the influence of the two resonances. Tunnel junction characteristics show that the fermi surface nesting depends on the crystallographic direction.

Microcrystals of orthorhombic nickel (II) oxalate dihydrate were synthesized through a precipitation reaction of aqueous solutions of nickel chloride and oxalic acid.Preparacion para radiografia de columna lumbosacra sanitas magnetic susceptibility exhibits a sharp peak at 3.3 K and a broad rounded maximum near 43 K. We associated the lower maximum with a metamagnetic transition that occurs when the magnetic field is about ≥3.5 T. The maximum at 43 K is typical of 1D antiferromagnets, whereas weak ferromagnetism behavior was observed in the range of 3.3–43 K.

Material and methods: retrospective analysis of the short-term results (penile length, angle of curvature and erectile function) of treating peyronie’s disease in 10 patients through cavernoplasty with oral mucosa graft.Preparacion para radiografia de columna lumbosacra sanitas essentially, the treatment included the incision of the fibrotic plaque with electrical scalpel and the subsequent coating of the cavernous defect using a patch of oral mucosa. At month 6, we measured the penile length and curvature and recorded the erectile function using the international index of erectile function-5 (IIEF-5) questionnaire. Finally, the patients were asked "would you undergo the same operation again?".

Results: the mean age was 53.4 years. The average and median follow-up was 22.7 months and 24 months, respectively. The mean preoperative curvature was 68.5° (50°-90°), the mean penile length was 11.2cm (9-15) and the mean IIEF-5 score was 16.1 (8-25). The mean postoperative penile length was 10.7cm, and the mean IIEF-5 score was 18.9.Preparacion para radiografia de columna lumbosacra sanitas the differences between the preoperative and postoperative values were not statistically significant (P=ns). One patient developed erectile dysfunction. In all cases, the residual curvature was <20°. Nine patients (90%) stated that they would undergo the same operation.

Abstract: objective: the aim of the study was to analyse the clinical-demographic variables of the series and the predictors of urethral stricture recurrence after endoscopic urethrotomy.: material and methods: we retrospectively analysed 67 patients who … … Title translation

Material and methods: we retrospectively analysed 67 patients who underwent sachse endoscopic urethrotomy between june 2006 and september 2014. Those patients who had previously undergone endoscopic urethrotomy or urethroplasty were excluded.Preparacion para radiografia de columna lumbosacra sanitas the other patients who presented urethral stricture were included. We analysed age, weight, smoking habit, and cardiovascular risk factors, as well as the number, location, length and aetiology of the strictures, previous urethrotomies, vesical catheter duration and postsurgical dilatations. A univariate and multivariate analysis was conducted using the chi-squared test or fisher’s test and logistic regression to identify the variables related to recurrence.

Results: thirty-seven percent of the patients had a relapse. The majority of the patients were older than 60 years (56.7%), obese (74.6%), nonsmokers (88%) and had no cardiovascular factors (56.7%). The majority of the strictures were single (94%), <1cm (82%), bulbar urethral (64.2%), iatrogenic (67.2%) and with no prior urethrotomy (89.6%).Preparacion para radiografia de columna lumbosacra sanitas the majority of the patients carried a vesical catheter for <15 days (85.1%) and did not undergo postsurgical dilatation (65.7%). Only the length of the stricture was an independent risk factor for recurrence (P=.025; relative risk, 5.7; 95% CI 1.21-26.41).

Conclusions: in the treatment of urethral strictures through endoscopic urethrotomy, a stricture length >1cm is the only factor that predicts an increase in the risk of recurrence. We found no clinical or demographic factors that caused an increase in the incidence of recurrence. Similarly, technical factors such as increasing the bladder catheterisation time and urethral dilatations did not change the course of the disease. Their routine use is therefore unnecessary.

Materials and method: A retrospective study was conducted on 629 patients with localised prostate cancer (pn0-pnx) who were treated with prostatectomy and with a prostate-specific antigen (PSA) value <0.2ng/ml at 2-3 months. Biochemical recurrence was defined as a PSA >0.4ng/ml. A multivariate cox regression analysis was performed. A score (0-2) was assigned according to the hazard ratio of the significant variables. The score summation defined the risk summation.

Results: A total of 19.7% of the patients were pt3, 24.2% had a gleason score ≥ 8, and 26.3% had positive surgical margins. The median follow-up was 82 months. Some 26.6% of the patients experienced biochemical recurrence. The identified prognostic variables independent of biochemical recurrence were a gleason score =7 (4+3) (HR, 2.01; P=.008), a gleason score ≥ 8 (HR, 3.07; P <.001), a pt3b stage (HR, 1.93; p=.008) and a positive surgical margin (HR, 2.20; P<.001).Preparacion para radiografia de columna lumbosacra sanitas we assigned 0 points to patients without risk prognosis variables; 1 point to patients with gleason scores =7 (4+3), pt3b or positive surgical margins; and 2 points to patients with gleason scores ≥ 8. The patients with a risk summation ≤ 2 had >50% survival free of biochemical recurrence at 5 and 8 years. In contrast, the patients with a risk summation ≥ 3 had <44% survival free of biochemical recurrence.

Background: long non-coding rnas (lncrnas) have emerged as key players in a remarkably variety of biological processes and pathologic conditions, including cancer. Next-generation sequencing technologies and bioinformatics procedures predict the existence of tens of thousands of lncrnas, from which we know the functions of only a handful of them, and very little is known in cancer types such as head and neck squamous cell carcinomas (hnsccs).

Results: here, we use rnaseq expression data from the cancer genome atlas (TCGA) and various statistic and software tools in order to get insight about the lncrnome in HNSCC.Preparacion para radiografia de columna lumbosacra sanitas based on lncrna expression across 426 samples, we discover five distinct tumor clusters that we compare with reported clusters based on various genomic/genetic features. Results demonstrate significant associations between lncrna-based clustering and DNA methylation, TP53 mutation, and human papillomavirus infection. Using "guilt-by-association" procedures, we infer the possible biological functions of representative lncrnas of each cluster. Furthermore, we found that lncrna clustering is correlated with some important clinical and pathologic features, including patient survival after treatment, tumor grade, or sub-anatomical location.

Objectives: to identify the post-prostatectomy prognostic factors of biochemical recurrence (BCR) and develop a predictive model for BCR based on predictive pathological variables after radical prostatectomy (RP).Preparacion para radiografia de columna lumbosacra sanitas

Methods: we retrospectively analysed patients with clinically localised prostate cancer treated with RP as monotherapy with a minimum follow up period of 12 months. We considered BCR to be the persistence or elevation of PSA levels after RP of> 0,4 ng/ml, and rising in the following determination. We performed uni-and multivariate analysis, using the logistic regression test to determine the variables associated with BCR. We developed a mathematical model to estimate BCR, based on the variables identified, with a logistic function equation and then designed an excel spreadsheet to apply it. Calibration and discrimination were performed by way of a hosmer-lemeshow test and an ROC curve.

Results: 693 patients were included. Average age was 63.5 years and average follow up was 88.5 months.Preparacion para radiografia de columna lumbosacra sanitas BCR was observed in 218 patients. The average time to BCR was 35.5 months, and 90% of the cases occurred in the first 7 years. In the multivariate analysis, the PSA, gleason score (GS) = 7(4+3), pathological stage pt3b and affectation of the surgical margin (SM) were identified as independent prognostic pathological variables related to BCR (p〈0,001). The above four variables were included into the equation of the model. Specificity and sensitivity were 90.6% and 50.2%. Its predictive capacity was 80.5% (CI 95% 76,80 -84.3).

Conclusions: PSA, GS = 7(4+3), pathological stage pt3b and PSM were found to be the independent prognostic pathological variables related to BCR-free survival. The predictive model developed permits BCR risk estimation with a reliability of 80.5%

Objective: gross hematuria in the immediate postoperative radical prostatectomy is a rare complication. According to different series reviewed, significant bleeding after this surgery appears between 0.5-1.5% of the cases.

Methods: 58 year old male with localized prostate cancer who underwent open radical prostatectomy with preservation of the neurovascular bundles and a left accessory pudendal branch. In the 4th postoperative day patient presented severe hematuria and urethral bleeding requiring continuous bladder irrigation and blood transfusion. Given the persistence of bleeding despite conservative measures CT-angiography was performed demonstrating active bleeding at a bulbar artery from the left internal pudendal artery without associated pelvic hematoma

Results: given the findings selective embolization was performed with absorbable material stopping the bleeding. Three months later the patient maintains urinary continence and erectile function with tadalafil.

Conclusions: urethral bleeding after radical prostatectomy is a rare complication the cause of which is distal to the urinary sphincter unrelated to the pelvic vessels. The performance of CT angiography and subsequent embolization is the treatment of choice, avoiding open surgical revision, with less morbidity.
