Prognostic factors in early-stage leiomyosarcoma of the uterus.

Uterine leiomyosarcomas (LMSs) are rare cancers representing less than 1% of all uterine malignancies. Clinical International Federation of Gynecology and Obstetrics (FIGO) stage is the most important prognostic factor. Other significant prognostic factors, especially for early stages, are difficult to establish because most of the published studies have included localized and extra-pelvian sarcomas. The aim of our study was to search for significant prognostic factors in clinical stage I and II uterine LMS. The pathologic features of 108 uterine LMS including 72 stage I and II lesions were reviewed using standardized criteria. The prognostic significance of different pathologic features was assessed. The median follow-up in the whole group was 64 months (range, 6-223 months). The 5-year overall survival (OS) and metastasis-free interval and local relapse-free interval rates in the whole group and early-stage group (FIGO stages I and II) were 40% and 57%, 42% and 50%, 56% and 62%, respectively. Clinical FIGO stage was the most important prognostic factor for OS in the whole group (P = 4 x 10). In the stage I and II group, macroscopic circumscription was the most significant factor predicting OS (P = 0.001). In the same group, mitotic score and vascular invasion were associated with metastasis-free interval (P = 0.03 and P = 0.04, respectively). Uterine LMSs diagnosed using standardized criteria have a poor prognosis, and clinical FIGO stage is an ominous prognostic factor. In early-stage LMS, pathologic features such as mitotic score, vascular invasion, and tumor circumscription significantly impact patient outcome.

Novel role of a family of major facilitator transporters in biofilm development and virulence of Candida albicans.

The QDR (quinidine drug resistance) family of genes encodes transporters belonging to the MFS (major facilitator superfamily) of proteins. We show that QDR transporters, which are localized to the plasma membrane, do not play a role in drug transport. Hence, null mutants of QDR1, QDR2 and QDR3 display no alterations in susceptibility to azoles, polyenes, echinocandins, polyamines or quinolines, or to cell wall inhibitors and many other stresses. However, the deletion of QDR genes, individually or collectively, led to defects in biofilm architecture and thickness. Interestingly, QDR-lacking strains also displayed attenuated virulence, but the strongest effect was observed with qdr2∆, qdr3∆ and in qdr1/2/3∆ strains. Notably, the attenuated virulence and biofilm defects could be reversed upon reintegration of QDR genes. Transcripts profiling confirmed differential expression of many biofilm and virulence-related genes in the deletion strains as compared with wild-type Candida albicans cells. Furthermore, lipidomic analysis of QDR-deletion mutants suggests massive remodelling of lipids, which may affect cell signalling, leading to the defect in biofilm development and attenuation of virulence. In summary, the results of the present study show that QDR paralogues encoding MFS antiporters do not display conserved functional linkage as drug transporters and perform functions that significantly affect the virulence of C. albicans.

Uso de micorrizas e rizóbio em cultivo consorciado de eucalipto e sesbânia: I - Crescimento, absorção e tranferência de nitrogênio entre plantas

Realizou-se um experimento em casa de vegetação para avaliar os efeitos de fungos micorrízicos arbusculares (FMAs) e rizóbio na produção de matéria seca, na absorção e na eficiência de utilização de N por plantas de Eucalyptus grandis e Sesbania virgata, cultivadas em consorciação. Avaliou-se, também, a transferência de N da sesbânia para o eucalipto, utilizando-se o isótopo 15N. Os tratamentos constaram da inoculação, ou não, com FMAs em ambas as espécies de plantas e da inoculação, ou não, com rizóbio na sesbânia. Utilizaram-se vasos plásticos subdivididos em três compartimentos (A, B e C), cada um com 2 L de capacidade. Os compartimentos A e B foram separados por uma parede plástica e entre os compartimentos B e C foi colocada uma tela com poros de 40 mm que permitiu somente a passagem de hifas, mas não de raízes. A sesbânia foi cultivada com suas raízes subdivididas entre o compartimento A e B e o eucalipto foi cultivado no compartimento C. No compartimento A, foram adicionados 7 mg kg-1 de 15N-(NH4)2SO4 com 99 % de 15N. As plantas foram avaliadas aos 100 dias. Nos tratamentos com inoculação com o rizóbio, com FMAs ou com FMAs + rizóbio, foram observados, nas plantas de eucalipto, aumentos na produção de matéria seca total de 119, 223 e 209 %, respectivamente, e aumentos no conteúdo de N de 125, 247 e 310 %, respectivamente, quando comparados aos resultados do tratamento-controle. Nas plantas de sesbânia, foram observados aumentos no conteúdo de N e decréscimo na relação C/N em todos os tratamentos inoculados com os microrganismos. A eficiência de utilização de N foi maior nas plantas de eucalipto quando inoculadas com FMAs e não variou com os tratamentos nas plantas de sesbânia. Foi observada a transferência de 15N das plantas de sesbânia para o eucalipto em todos os tratamentos.

Characterisation of two soluble metalloexopeptidases in the protozoan parasite Leishmania major.

Two soluble exopeptidases were identified in promastigotes of Leishmania major, using an iodinated model tetrapeptide (LIAY) as substrate. Similar activities were also detected in L. major amastigotes and in different species of Leishmania promastigotes. A carboxy- and an aminopeptidase activity were resolved and isolated by anion exchange and gel permeation chromatographies. A single polypeptide of 62 kDa co-purified with the aminopeptidase activity. Optimum pH was neutral for the carboxypeptidase and neutral to alkaline for the aminopeptidase. Both activities were able to hydrolyse a dipeptide substrate (YL), and were inhibited by 20 microM bestatin and 200 microM 1,10-phenanthroline, but not by leupeptin, iodoacetamide and a range of other inhibitors. These results strongly suggest that both enzymes are metalloexopeptidases and thus represent a novel class of soluble peptidases in Leishmania.

Efeito da densidade de plantas e da adubação NPK na produção inicial de palmito de pupunheira

Avaliaram-se os efeitos da densidade de plantas e doses de adubação na produção de palmito de pupunheira, em condições de campo, na Fazenda Yuricam, Rio Preto da Eva (AM). O delineamento experimental foi de blocos casualizados com três repetições, com os tratamentos em arranjo fatorial 3 x 5, sendo avaliados os fatores: densidade de plantas (10.000; 5.000 e 3.333 plantas ha-1) e doses de adubação NPK (0-0-0; 112,5-12,5-90; 337,5-38-270; 225-90-180, 225-25-180 em kg ha-1 de N, P2O5 e K2O, respectivamente). Os resultados do primeiro ano de produção de palmito, em termos de estipes colhidas, para efeito das doses de adubação NPK, foram: 225-90-180 (66 %); 225-25-180 (57 %); 337,5-38-270 (50 %); 112,5-12,5-90 (26 %); 0-0-0 (1 %) - os números entre parênteses indicam os percentuais de plantas coletadas em relação às plantadas - e para efeitos de densidade: 3.333 plantas ha-1 (58 %); 5.000 plantas ha-1 (28 %); 10.000 plantas ha-1 (40 %). O tempo médio para extração de palmito foi menor na densidade de 3.333 plantas ha-1 (18,4 meses) e na dose de adubação NPK de 225-90-180 (18,1 meses). O efeito simples da adubação NPK dentro da densidade de 10.000 plantas ha-1 com a adubação 225-90-180 e 225-25-180 apresentou maior produção de palmito, com 841 e 779 kg ha-1, e de 1.154 e 1.223 kg ha-1 de estipe tenro, respectivamente, nas duas adubações.

Chest pulse-wave velocity: a novel approach to assess arterial stiffness.

Pulse-wave velocity (PWV) is considered as the gold-standard method to assess arterial stiffness, an independent predictor of cardiovascular morbidity and mortality. Current available devices that measure PWV need to be operated by skilled medical staff, thus, reducing the potential use of PWV in the ambulatory setting. In this paper, we present a new technique allowing continuous, unsupervised measurements of pulse transit times (PTT) in central arteries by means of a chest sensor. This technique relies on measuring the propagation time of pressure pulses from their genesis in the left ventricle to their later arrival at the cutaneous vasculature on the sternum. Combined thoracic impedance cardiography and phonocardiography are used to detect the opening of the aortic valve, from which a pre-ejection period (PEP) value is estimated. Multichannel reflective photoplethysmography at the sternum is used to detect the distal pulse-arrival time (PAT). A PTT value is then calculated as PTT = PAT - PEP. After optimizing the parameters of the chest PTT calculation algorithm on a nine-subject cohort, a prospective validation study involving 31 normo- and hypertensive subjects was performed. 1/chest PTT correlated very well with the COMPLIOR carotid to femoral PWV (r = 0.88, p < 10 (-9)). Finally, an empirical method to map chest PTT values onto chest PWV values is explored.

Cataractogenesis after total body irradiation.

PURPOSE: To evaluate the prognostic factors and the ophthalmologic follow-up on cataract formation following total body irradiation (TBI) prior to bone marrow transplantation (BMT). METHODS AND MATERIALS: Between 1980 and 1992, 494 patients were referred to our department for TBI prior to BMT. The mean age was 32 +/- 11 (median: 32, range: 2-63) years and the male to female ratio was 1.6 (304:190). The majority of patients were treated for acute leukemia (lymphoblastic, n = 177, 36%; or nonlymphoblastic , n = 139, 28%); 80 (16%) for chronic myeloid leukemia, 60 (12%) for non-Hodgkin's lymphoma, 23 (5%) for multiple myeloma, and 15 (3%) for other malignancies. Two hundred and fifty-four (51%) patients were grafted in the first complete remission (CR), 118 (24%) in second CR. Allogenic BMT was performed in 210 (43%) patients, and autologous BMT in 284 (57%). Methotrexate combined to steroids (n = 47, 22%) or to cyclosporine (n = 163, 78%) was administered for graft-versus-host disease (GvHD) prophylaxis. In 188 patients (38%), heparin was used in the prevention of veno-occlusive disease (VOD) of the liver. Furthermore, steroid administration was registered in 223 (45%). The conditioning chemotherapy consisted of cyclophosphamide (Cy) alone in 332 (67%) patients. Total-body irradiation was administered either in single dose (STBI; 10 Gy in 1 day, n = 291) or in six fractions (FTBI; 12 Gy over 3 consecutive days, n = 203) before BMT. The mean instantaneous dose rate was 0.0574 +/- 0.0289 Gy/min (0.024-0.1783). It was < 0.048 Gy/min in 157 patients (LOW group), > or = 0.048 Gy/min and <0.09 Gy/min in 301 patients (MEDIUM group), and > or = 0.09 Gy/min in 36 patients (HIGH group). RESULTS: When considering all patients, 42 (8.5%) patients developed cataracts after 13 to 72 months (median: 42 months) with a 5-year estimated cataract incidence (ECI) of 23%. Thirty-three (11.3%) out of 291 patients in the STBI group, and 9 (4.4%) out of 203 patients in the FTBI group developed cataracts with 5-year estimated incidences of 34 and 11%, respectively (p = 0.0004). Seven (19.4%) out of 36 patients in the HIGH group, 33 (10.9%) out of 301 in the MEDIUM group, and 2 (1.2%) out of 157 in the LOW group developed cataracts with respective 5-year cataract incidences of 54%, 30%, and 3.5% (HIGH vs. MEDIUM, p = 0.07; MEDIUM vs. LOW, p = 0.0001; HIGH vs. LOW, p < 0.0001). On the other hand, patients who received heparin as prophylactic treatment against VOD of the liver had less cataracts than those who did not receive (5-year ECI of 16% vs. 28%, respectively; p = 0.01). There was no statistically significant difference in terms of 5-year ECI according to age, sex, administration of steroids, GvHD prophylaxis, type of BMT, or previous cranial radiotherapy in children. Multivariate analysis revealed that the instantaneous dose rate (p = 0.001), and the administration of heparin against VOD (p = 0.05) were the two independent factors influencing the cataract incidence, while age, fractionation, and use of steroids were not. Among the 42 patients who developed cataracts, 38 had bilateral extracapsular cataract extraction and intraocular lens implantation, and only 4 (10%) developed secondary cataracts in a median follow-up period of 39 months. CONCLUSION: Among the abovementioned TBI parameters, high instantaneous dose rate seems to be the main risk factor of cataract formation, and the administration of heparin appears to have a protective role in cataractogenesis. On the other hand, ionizing radiation seems to have a protective effect on posterior capsule opacification following extracapsular cataract extraction and intraocular lens implantation.

Plaque characteristics and arterial remodeling in coronary and peripheral arterial systems.

BACKGROUND: Few studies have examined plaque characteristics among multiple arterial beds in vivo. The purpose of this study was to compare the plaque morphology and arterial remodeling between coronary and peripheral arteries using gray-scale and radiofrequency intravascular ultrasound (IVUS) at clinical presentation. METHODS AND RESULTS: IVUS imaging was performed in 68 patients with coronary and 93 with peripheral artery lesions (29 carotid, 50 renal, and 14 iliac arteries). Plaques were classified as fibroatheroma (VH-FA) (further subclassified as thin-capped [VH-TCFA] and thick-capped [VH-ThCFA]), fibrocalcific plaque (VH-FC) and pathological intimal thickening (VH-PIT). Plaque rupture (13% of coronary, 7% of carotid, 6% of renal, and 7% of iliac arteries; P = NS) and VH-TCFA (37% of coronary, 24% of carotid, 16% of renal, and 7% of iliac arteries; P = 0.02) were observed in all arteries. Compared with coronary arteries, VH-FA was less frequently observed in renal (P < 0.001) and iliac arteries (P < 0.006). Lesions with positive remodeling demonstrated more characteristics of VH-FA in coronary (84% vs. 25%, P < 0.001), carotid (72% vs. 20%, P = 0.001), and renal arteries (42% vs. 4%, P = 0.001) compared with those with intermediate/negative remodeling. There was positive relationship between remodeling index and percent necrotic area in all four arteries. CONCLUSIONS: Atherosclerotic plaque phenotypes were heterogeneous among four different arteries; renal and iliac arteries had more stable phenotypes compared with coronary artery. In contrast, the associations of remodeling pattern with plaque phenotype and composition were similar among the various arterial beds.

Heterogeneity of the induction of HLA-DR expression by human immune interferon on glioma cell lines and their clones.

The modulation of HLA-DR and HLA-A, -B, and -C by human recombinant immune interferon (IFN-gamma) was studied on 10 malignant glioma cell lines established in our laboratory, on 8 clones or subclones derived from these lines, and on a fetal astrocyte cell line. Comparative studies were performed with recombinant leukocyte interferon (IFN-alpha). The results not only confirmed the selective activity of IFN-gamma on the modulation of HLA-DR expression, as opposed to that of IFN-alpha, but also demonstrated a marked heterogeneity in the response of glioma cell lines and their clones to the two types of IFN tested. For example, all 3 clones of an inducible cell line could be modulated to express HLA-DR, whereas only 2 of 5 clones derived from a noninducible line were modulated. This heterogeneity did not seem to be due to the absence of the receptor for IFN-gamma on the surface of these cells, since almost all of the cell lines or clones tested (17 of 19) responded to IFN-gamma by the induction or enhancement of the expression for either HLA-DR or HLA-A, -B, and -C (or both). The heterogeneity of induction was also demonstrated between clones derived from a glioma line that did not express HLA-DR after IFN-gamma treatment. The production of HLA-DR by one of the clones was abundant enough to be confirmed by immunoprecipitation and sodium dodecyl sulfate-polyacrylamide gel electrophoresis analysis.
