Type of funding sources: Public hospital(s). Main funding source(s): Mayo Clinic Foundation
Background
Left atrial (LA) volume is linked to outcome in degenerative mitral regurgitation (DMR) but does not encompass LA function assessment. Thus, we ought to determine the prognostic role of left atrial coupling-index (LACI), as left atrial volume-index (LAVI) by Tissue-Doppler-Imaging a’ (TDI-a’), in a large cohort of DMR.
Methods
All consecutive 4792 patients (61 ± 16 years, 48% women) with isolated degenerative mitral valve disease diagnosed at Mayo Clinic 2003-2011, comprehensively characterized, in whom LAVI and TDI-a’ in sinus rhythm was prospectively measured in routine practice, was enrolled and their long-term survival analyzed.
Results
LACI (5.8 ± 3.7–T1 < 3.8; T2 3.8-6.3; T3 > 6.3) was significantly higher through different DMR grades (no, mild, moderate, severe DMR: 3.77 ± 2.26, 5.08 ± 2.95, 6.54 ± 3.74 and 7.84 ±4.29 respectively; p < 0.0001). Independent determinants of LA dysfunction assessed by LACI were age, E/e’, left-ventricle (LV) end-systolic-diameter, mitral-regurgitation (MR) grade, and LV ejection-fraction (all P ≤ 0.0001). LACI > 6 was independently associated with dyspnea, edema, more severe functional tricuspid-regurgitation and elevated pulmonary artery pressure, irrespective of age, sex, Charlson-comorbidity-index, ventricular function and MR severity. Total follow-up was 7.03 ± 3.0 years, during which 1146 (24%) underwent mitral-valve surgery (94% repair-6% replacement) and 880 (18%) died, 780 under medical treatment and 100 after surgery. Overall survival throughout follow-up (10-year 76 ± 1%) was strongly associated with LACI (88 ± 1% vs. 78 ± 1% and 62 ± 2% for LACI <3.8, 3.8-6.3 and ≥6.3, P < 0.0001) even adjusting comprehensively, including for DMR severity (adjusted-hazard-ratio 1.23[1.07-1.43] for LACI > 5.79, P = 0.005). Mortality under medical management was profoundly affected by LACI (adjusted-hazard-ratio 1.11[1.05-1.18] per 3 unit increment; 1.35[1.15-1.58] for LACI > 5.79 vs. ≤5.79, both P = 0.0002). Survival improved after mitral surgery (time-dependent adjusted-hazard-ratio 0.40[0.28-0.65], P < 0.0001) but remained humbly linked to LACI (10-year 93 ± 3% vs. 90 ± 2% and 80 ± 3% for LACI tertiles, P = 0.0008). Most importantly, LACI provided incremental prognostic information over LAVI and other conventional determinants of survival (P < 0.0001) with Net-reclassification-improvement vs. LAVI of 0.21 ± 0.02, P < 0.0001.
Conclusion
LA function assessed by LACI in routine practice, by conventional echocardiographic measurements, displays incremental and independent link to excess-mortality, considerable under medical management and partially alleviated by mitral surgery. Thus, LACI is a simple tool of crucial interest in DMR risk-stratification.

Abstract
In seasonal breeders, reproductive seasonality can have a substantial influence on the efficiency of assisted reproductive technologies. This study assessed seasonal effects on cleavage and blastocyst rates, as well as on quality of invitro-produced (IVP) goat embryos over 18 months. In total, 2348 (autumn: 811, spring: 404, summer: 639, and, winter: 494) cumulus–oocyte complexes (COC) were recovered from slaughterhouse ovaries during 49 replicates (autumn: 17, spring: 7, summer: 15, and, winter: 10) and matured in TCM-199 with 10ng mL−1 epidermal growth factor and 100µM cysteamine for 22h at 38.8°C (5% CO2 in air). Matured oocytes were fertilized with frozen/thawed semen in synthetic oviductal fluid (SOF) with 10% oestrus sheep serum. Sperm and oocytes were co-incubated for 16h at 38.8°C in a humidified atmosphere of 5% CO2 in air. Presumptive zygotes were cultured in SOF medium supplemented with bovine serum albumin (3mg mL−1) for 8 days at 38.8°C in a humidified atmosphere of 5% O2, 5% CO2 and 90% N2. At Day 2, 10% fetal calf serum was added to the culture droplets. The embryos produced were fixed and stained with Hoechst to count their total number of cells, under an epifluorescence microscope. The results of cleavage and blastocyst rates, including hatching rate, from each routine of IVEP were considered as replicates. These data were tested for normality by the Shapiro-Wilk test, before being subjected to ANOVA, followed by Tukey HSD test. The odds ratio (OR) among seasons (autumn: breeding; spring: anoestrus) were calculated. Values of P<0.05 were considered as significant, and the data reported are mean±s.e.m. Cleavage rate was lower (P<0.05) in spring (51±7.1%) than in either autumn (72±2.1%) or summer (71±2.0%) while winter (66±4.1%) had an intermediate value, being similar (P> 0.05) to all others. Indeed, greater possibility of cleavage was observed in autumn (OR: 2.43) and summer (OR: 2.39) compared with spring. The blastocyst rate from cleaved embryos was greater (P <0.05) in autumn (73±2.7%) than in spring (55±2.6%; OR: 2.18). As a result, the blastocyst formation rate from the initial number of COC entering IVM was greater (P<0.05) in autumn (52±2.5%) than in spring: 28±4.7%, summer: 45±2.3%, and winter: 42±2.1%; indeed, the spring season resulted in the lowest rate (P<0.05), compared with other seasons. Moreover, the OR in the blastocyst rate from initial number of COC was greater (P<0.05) in autumn compared with all other seasons and lower in spring compared with winter (OR: 0.54) and summer (OR: 0.48). There were no differences (P> 0.05) in the embryo hatching (mean: 66±2.0%) and blastocyst cell number (mean: 193±2.0 cells). In conclusion, the breeding season (autumn) leads to improved oocyte developmental competence, resulting in greater cleavage and blastocyst yield, whereas embryo quality remained similar throughout the year. Further studies at the molecular level might indicate the mechanisms involved and provide clues to alleviate the negative effect of season.

Abstract
Antral follicle count (AFC) performed after an oestrus synchronization protocol has been studied as a tool to select ewes with high potential for invivo embryo production (Pinto et al. 2018 Theriogenology 113, 146-152). However, it would be interesting to know whether AFC assessed on a random day of the oestrous cycle correlates with the superovulatory response. The present study was conducted to evaluate the correlation between AFC at the beginning of progesterone (P4)-based oestrus synchronization protocol used as basis of superovulatory treatment and the number of corpora lutea (CL) 12h before recovery of embryos in Santa Inês ewes. The study was conducted during September and October in northeast Brazil (03°40′26″S and 40°14′20″W) using 8 adult Santa Inês ewes. On a random day of oestrous cycle (Day 0) all ewes received an intravaginal device (CIDR) of progesterone (0.3g, Eazi-breed, Zoetis), which remained for 9 days. On Day 7, the pFSH (133mg, Folltropin V, Vetoquinol) treatment began, with 6 decreasing doses (25, 25, 15, 15, 10, and 10%) injected IM at 12-h intervals. On Day 9, 2 equal doses of D-cloprostenol were injected at a 12-h interval (37.5µg, Prolise, Agener União). All ewes showed oestrus and were mated by fertile rams. Flunixin meglumine (24.9 mg; Banamine, MSD Animal Health) was administered IM on Days 12, 13, and 15. On Day 16, non-surgical embryo recovery (NSER) was performed after cervical dilation using D-cloprostenol and oestradiol benzoate at 16h and oxytocin 20min before. Transrectal B-mode ultrasound evaluations (Z5 Vet, Mindray), frequency 7.5MHz, were performed on Day 0 and 7 and 12h before NSER to evaluate the ovarian population present. Pearson correlation analysis (P<0.05) was performed using Bioestat 5.3 software. The number of AFC per ewe at the beginning of the protocol and on Day 7 were 9.9±2.7 and 11±3.2, respectively. The numbers of CL, recovered embryos, and viable embryos were 14.0±3.5, 8.2±10.9, and 6.0±11.0, respectively. There was no correlation of AFC on a random day of oestrous cycle with the number of AFC on Day 7 (P=0.42), number of corpora lutea (P=0.44), number of recovered embryos (P=0.18), or number of viable embryos (P=0.11) in superovulated ewes. In conclusion, we did not find significant correlations between AFC on a random day of oestrous cycle and the superovulatory/embryos response in Santa Inês ewes.

Abstract
BACKGROUND Preprescription authorization (PPA) and postprescription review with feedback (PPRF) were successively implemented in 2012 and 2016 in our 1500-bed hospital. AIM The impact of PPA and PPRF on carbapenems use and resistance levels of Pseudomonas aeruginosa was assessed in three intensive care units (ICUs). METHODS Carbapenems use (in DDDs/1000 occupied bed-days) and resistance of P. aeruginosa (percentage of non-susceptible (I+R) isolates to imipenem and/or meropenem) were analysed using a controlled interrupted time-series method. Two periods were compared: 2012-2015 (PPA) and 2016-2017 (PPA+PPRF). Models were adjusted on the annual incidence of extended-spectrum β-lactamase-producing enterobacteriacae. FINDINGS Carbapenem use was stable over the PPA period in all ICUs, with a significant change of slope over the PPA+PPRF period only in ICU1 (β2 = -12.8, 95% confidence interval (CI) = -19.5 to -6.1). There was a switch from imipenem to meropenem during the PPA period in all three units. Resistances of P. aeruginosa were stable over the study period in ICU1 and ICU2, and significantly decreased over the PPA+PPRF period in ICU3 (β2 = -0.18, CI = -0.3 to -0.03). CONCLUSION In real-life conditions and with the same antimicrobial stewardship programme (AMSP) led by a single team, the impact of PPRF was heterogeneous between ICUs. Factors driving the impact of AMSPs should be further assessed in comparable settings through real-life data, to target where they could prove cost-effective.

Abstract
Unmanned air systems are becoming ever more important in modern societies but raise a number of unresolved problems. There are legal issues with the operation of these vehicles in nonsegregated airspace, and a pressing requirement to solve these issues is the development and testing of reliable and safe mechanisms to avoid collision in flight. In this article, we describe a sense and avoid subsystem developed for a maritime patrol unmanned air system. The article starts with a description of the unmanned air system, that was developed specifically for maritime patrol operations, and proceeds with a discussion of possible ways to guarantee that the unmanned air system does not collide with other flying objects. In the system developed, the position of the unmanned air system is obtained by the global positioning system and that of other flying objects is reported via a data link with a ground control station. This assumes that the detection of those flying objects is done by a radar in the ground or by self-reporting via a traffic monitoring system (such as automatic identification system). The algorithm developed is based on game theory. The approach is to handle both the procedures, threat detection phase and collision avoidance maneuver, in a unified fashion, where the optimal command for each possible relative attitude of the obstacle is computed off-line, therefore requiring low processing power for real-time operation. This work was done under the research project named SEAGULL that aims to improve maritime situational awareness using fleets of unmanned air system, where collision avoidance becomes a major concern.

Abstract
BACKGROUND Carbapenem-resistant Enterobacteriaceae (CRE) and vancomycin-resistant enterococci (VRE) carriage are increasing worldwide. Faecal microbiota transplantation (FMT) appears to be an attractive option for decolonization. This study aimed to evaluate CRE vs VRE clearance by FMT among carriers. METHODS A multi-centre trial was undertaken on patients with CRE or VRE digestive tract colonization who received FMT between January 2015 and April 2017. Adult patients with CRE or VRE colonization, confirmed by three consecutive rectal swabs at weekly intervals, including one in the week prior to FMT, were included in the study. Patients with immunosuppression or concomitant antibiotic prescription at the time of FMT were excluded. Successful decolonization was determined by at least two consecutive negative rectal swabs [polymerase chain reaction (PCR) and culture] on Days 7, 14, 21 and 28, and monthly for three months following FMT. RESULTS Seventeen patients were included, with a median age of 73 years [interquartile range (IQR) 64.3-79.0]. Median duration of carriage of CRE or VRE before FMT was 62.5 days (IQR 57.0-77.5). One week after FMT, three of eight patients were free of CRE colonization and three of nine patients were free of VRE colonization. After three months, four of eight patients were free of CRE colonization and seven of eight patients were free of VRE colonization. Qualitative PCR results were concordant with culture. Six patients received antibiotics during follow-up, three in each group. No adverse events were reported. CONCLUSION CRE and VRE clearance rates were not significantly different in this study, possibly due to the small sample size, but a trend was observed. These data should be confirmed by larger cohorts and randomized trials.

Abstract
Carbapenem-resistant Enterobacteriaceae (CRE) or vancomycin-resistant enterococci (VRE) carriage present a major public health challenge. Decolonization strategies are lacking. We aimed to evaluate the impact of faecal microbiota transplantation (FMT) on a cohort of patients with digestive tract colonization by CRE or VRE. Eight patients were included: six carrying CRE and two colonized by VRE. One month after FMT, two patients were free from CRE carriage, and another patient was free from VRE after three months. In our experience, this strategy is safe.

Abstract
Extracorporeal shock wave lithotripsy (ESWL) is a common procedure in the treatment of renal calculi. There have been major complications reported with ESWL such as acute pancreatitis, bower perforation, venous thrombosis, and biliary obstruction. There are few reports in the literature of necrotizing pancreatitis secondary to ESWL. We have a case report of a 29-year-old female that developed an abdominal compartment syndrome with an acute necrotizing pancreatitis hours after extracorporeal shock wave lithotripsy.

Abstract
The emergence of bacterial resistance and the lack of new antibiotics in the pipeline represent a public health priority. Maximizing the quality of antibiotic prescriptions is therefore of major importance in terms of adequate preparation and administration modalities. Adequate preparation prevents the inactivation of antibiotics and is a prerequisite to maximizing their efficacy (taking into account the pharmacokinetic/pharmacodynamic relationship) and to minimizing their toxicity. Many antibiotic guidelines address the choice of drugs and treatment duration but none of them exclusively address preparation and administration modalities. These guidelines are based on the available literature and offer essential data for a proper antibiotic preparation and administration by physicians and nurses. They may lead to a better efficacy and to a reduced antibiotic resistance. Such guidelines also contribute to a proper use of drugs and improve the interaction between inpatient and outpatient care for a better overall management of patients.

Abstract
Avaliaram-se os efeitos dos tipos de suplementação sobre o desempenho produtivo e o comportamento ingestivo diurno de cordeiros mestiços Santa Inês mantidos em pastagem de capim-aruana (Panicum maximum cv. Aruana) sobressemeado com aveia branca (Avena sativa L.) e azevém (Lolium multiflorum Lam.), em um delineamento inteiramente ao acaso, com três tratamentos e três repetições. Os cordeiros foram distribuídos aleatoriamente em três sistemas alimentares, com seis animais cada, sendo: PAST - cordeiros mantidos exclusivamente a pasto; SIL - cordeiros mantidos em pastagem recebendo suplementação (1,0% do peso vivo) com silagem de milho; CONC - cordeiros mantidos em pastagem recebendo suplementação (1,0% do peso vivo) com concentrado. Os cordeiros suplementados com concentrado apresentaram ganho de peso médio diário 37,5% superior aos mantidos em pastagem, mas não diferiram da suplementação com silagem de milho. O tempo de pastejo foi superior para os animais não suplementados quando comparados aos animais suplementados. Cordeiros mantidos a pasto e suplementados com silagem de milho ou concentrado ganham mais peso do que os cordeiros não suplementados.

Abstract
BACKGROUND Although hypercholesterolemia is a well-established risk factor for coronary heart disease, evidence suggests that increased triglyceride (TG) concentrations are also an independent risk factor. TG concentrations >150mg/dl are observed nearly twice as often in subjects with atherosclerosis. We assessed the association between hypertriglyceridemia and protein oxidation and proinflammatory markers in normocholesterolemic and hypercholesterolemic individuals. METHODS We included 127 volunteers enrolled in Cruz Alta, RS, Brazil. The patients were stratified based on total cholesterol and TG concentrations for analysis of associations with inflammation (high-sensitivity C-reactive protein - hs-CRP), endothelial dysfunction (nitric oxide - NOx) and oxidative stress (advanced oxidation protein products - AOPPs; ischemia-modified albumin - IMA). Correlations between variables were determined and multiple regression analysis was employed to investigate whether some variables correlate with TG concentrations. RESULTS Hypertriglyceridemia was related to oxidative stress and proinflammatory markers in individuals independent of total cholesterol concentrations. Moreover, the results indicate a stronger association of tested biomarkers with TG concentrations than with total cholesterol. The results indicate a positive correlation between oxidative stress and TG concentrations in the sera of hypercholesterolemia subjects. AOPPs and IMA concentrations were associated with the presence of hypertriglyceridemia in a manner that was independent of age, gender, hypertension and diabetes mellitus disease, smoking habits, sedentary lifestyle, BMI, waist circumference, LDL, HDL and total cholesterol concentrations. CONCLUSIONS We speculate that TG concentrations can reflect the enhancement of protein oxidation and proinflammation.

Abstract
Diffuse lipomatosis of the thyroid gland is a very rare disease, characterized by extensive infiltration of thyroid parenchyma by mature adipose tissue, usually not accompanied by amyloid fibrils deposition. The pathophysiology of adipose tissue infiltration in the thyroid gland remains unknown. We report a clinical case of a diffuse thyroid lipomatosis, whose immunohistochemical study of succinate dehydrogenase - subunit B (SDHB) revealed loss of expression of this protein in the follicular or adipose cells. We detected the presence of a recently described SDHB gene large deletion. Loss of mitochondrial SDHB expression may have a key role in understanding the pathophysiology of thyrolipomatosis, by regulating status of lipid metabolism.

Abstract
BACKGROUND Five Asociación de Hemato-Oncología de Centroamérica (AHOPCA) countries have used an adapted BFM-based protocol for childhood acute lymphoblastic leukemia (ALL). PROCEDURE In the AHOPCA-ALL 2008 protocol, patients were stratified by age, white blood cell count, immunophenotype, central nervous system involvement, day 8 prednisone response, and morphologic bone marrow response to induction therapy. Patients at Standard Risk (SR) received a three-drug induction regimen, a reinduction phase, and maintenance with protracted intrathecal therapy. Those at Intermediate (IR) and High Risk (HR) received, in addition, daunorubicin during induction therapy, a consolidation phase and two or three reinduction phases respectively. RESULTS From August 2008 through July 2012, 1,313 patients were enrolled: 353 in SR, 548 in IR, 412 in HR. During induction therapy, 3.0% of patients died, 2.7% abandoned treatment, 1.1% had resistant ALL, and 93.2% achieved morphological complete remission (CR). Deaths and abandonment in first CR occurred in 2.7% and in 7.0% of patients, respectively. The relapse rate at a median observation time of 2.1 years was 15.0%. At 3 years, the event-free survival (EFS) and overall survival (OS), with abandonment considered as an event, were 59.4% (SE 1.7) and 68.2% (SE 1.6). Three-year EFS was 68.5% (SE 3.0), 62.1% (SE 2.6), and 47.8% (SE 3.2) for SR, IR, and HR groups. Adolescents had a significantly higher relapse rate (P = 0.001). CONCLUSIONS This experience shows that common international studies are feasible in lower-middle income countries. Toxic deaths, abandonment of treatment, and relapses remain major obstacles to the successful treatment. Alternative treatment strategies may be beneficial.

Abstract
It's established that adherence rates to treatment are bad in chronic illnesses. The number of medicines prescribed and the rates of daily dosages have been shown to be of major influence for therapeutic compliance in AIDS or hypertension. Nevertheless, data on adherence to prescribed medications amongst diabetics are scarce. The aim of our study was to evaluate parameters influencing therapeutic compliance in type 2 diabetes. Adherence to treatment was evaluated by a questionnaire filled out during patient's hospitalisation in the diabetology department of a French general hospital of 450 beds. Factors influencing compliance were quantified taking into account demographic characteristics of our population, the treatments used, biological and medical data. 94 patients hospitalised for uncontrolled diabetes, aged 41-89 years, were studied. Non-adherence rate was high, 33 of them showed poor adherence to their drug treatment. Non-compliers were younger than compliant patients (56.5+/-12.1 vs. 65.5+/-12.5 years old; P<0.0001) and with a lower social position. Clinically, they were characterised by a shorter duration of diabetes and a lower number of clinical complications as macroangiopathy (6.9 vs. 33.3%; P=0.006). The number of daily doses or medicines didn't affect adherence rate. Improved control in therapeutic compliance may lead to better diabetic patients education. The implication is that instead of increasing the dose, changing the medication, or adding a second drug when glucose and HbA(1c)levels are high, clinicians should consider counselling patients on how to improve therapeutic compliance.

Abstract
6-Dimethylamino-4,4-diphenylheptane-3-one (methadone) is a synthetic opioid. Presence of an assymetrical carbon in its structure explains existence of two enantiomers. Levogyral enantiomer or R-methadone exhibits an 25 fold superior analgesic activity to the dextrogyral enantiomer S-methadone. In order to run separately a plasma assay of these two enantiomers, a chromatographic chiral separation method coupled with an ultraviolet detection has been performed. It allows selective assay of each enantiomer. This method, although an analytical interference with d-propoxyphene, is sensitive, reproductible, specific and shows a convenient resolution for the analysis of both the stereospecific and racemic forms. This method can be applied for pharmacokinetic study of the drug in patients treated by methadone.

Abstract
PURPOSE Cyclosporine administration is very effective in the case of immunological diseases of the cornea, conjunctive or uvea. Moreover, it is widely used in the case of high-risk rejection corneal transplantation. We present a preparation of cyclosporine 2% eye drops. METHODS Cyclosporine 2% eye drops are prepared following a particular formulation including one part commercially available cyclosporine oral solution (Sandimmun) diluted in four parts of sterile castor oil. Manufacturing procedures maintain the sterile state of the preparation with a laminar airflow hood placed in a particulate controlled room, with pharmacists, technicians and clerical personnel wearing sterile clothes. Physical and chemical monitoring during and after manufacture for each batch guarantees the process and minimizes the risk of batch rejection. Chemical analysis of cyclosporine is conducted using a validated stability-indicating high-performance liquid chromatographic assay (reverse-phase). Blood dosages taken after the first administration at the 24th hour (after administration of the 6th drop) check for systemic integration. RESULTS Cyclosporine 2% eye drops are fairly stable: 12 months after manufacturing, concentrations result in levels not statistically different from concentrations measured the day of preparation. After a daily regimen of six drops in the eye, cyclosporine 2% eye drops have a very low systemic bioavailability, because the blood concentrations only reach the detection limit of the fluorescence polarization immunoassay used for cyclosporine drug monitoring. This explains the absence of systemic toxicity. CONCLUSION Cyclosporine 2% eye drops can be available in the hospital pharmacy. The eye drops are stable at room temperature and can be delivered up to 12 months after manufacture. No local adverse effects have been noted, probably in relation with the very low concentration of ethanol in the ocular preparation.

Abstract
A technique for the analysis of the volatile compounds from fish tissue employing microwave distillation-solid-phase microextraction-gas chromatography-mass spectrometry is described. A qualitative listing of 174 compounds observed in the headspace is given, and a quantitative method for the determination of the off-flavor contaminants (2-methylisoborneol and geosmin) is presented. Borneol and decahydro-1-naphthol are used as the surrogate and internal standards, respectively. A linear calibration curve is obtained for 0.1 to 5 ppb with a recovery level of 60% at 2.5 ppb. Comparison of the instrumental method with a human flavor checker showed good agreement.

Abstract
Because most hemodialysis access fails at the venous side, we studied samples of brachial vein obtained during access creation in 15 patients with end-stage renal disease who gave consent. Veins were examined by computer-assisted histomorphometry, and the results correlated with the patients' clinical data. The mean venous medial width was 239 +/- 31 microm, and mean intimal width was 6.0 +/- 0.9 microm. Mean venous medial width was 358 +/- 74 microm and mean venous intimal width was 9.2 +/- 1.2 microm in the 4 patients who had been undergoing dialysis more than 6 months, compared with 196 +/- 23 microm and 4.9 +/- 0.8 microm, respectively, in the 11 patients undergoing dialysis less than 6 months (P < 0.01). The number of months undergoing hemodialysis correlated well with venous medial width (r = 0.79; P < 0.001). Correlation between number of months undergoing dialysis and intimal width did not reach statistical significance. Medial and intimal widths of the 4 patients with diabetes were not significantly different from those of the patients without diabetes. Serum parathyroid hormone level did not correlate with either medial or intimal venous width. We conclude there may be changes in the veins of hemodialysis patients with time that cause thickening of layers, even in veins not directly used for access. This may affect the creation or survival of subsequent vascular accesses.

Abstract
The diterpenes ent-kaur-16-en-19-oic acid, ent-kaur-9(11),16(17)-dien-19-oic acid and 3 alpha-angeloiloxy-ent-kaur-16-en-19-oic acid were identified as trypanosomicidal compounds of the ethanolic extract from the aerial parts of Wedelia paludosa D.C. (Asteraceae), showing activity up to the lowest dose of 0.68 mg/mL in the in vitro assay against trypomastigotes of T. cruzi, the causative agent of Chagas' disease (American trypanosomiasis). The other isolates, friedelan-3 beta-ol, ent-kaur-16 alpha-ol-19-oic acid, beta-amyrin acetate and (22-E)-stigmasta-5,22-dien-3 beta-ol, were inactive. This is the first report on the trypanosomicidal activity of ent-kaur-9(11),16(17)-dien-19-oic acid and 3 alpha-angeloiloxy-ent-kaur-16-en-19-oic acids; this effect was already known for ent-kaur-16-en-19-oic acid.

Abstract
A seven-iron ferredoxin was isolated from aerobically grown cells of the hyperthermoacidophilic archaeon Desulfurolobus ambivalens (DSM 3772). The protein is monomeric, with an apparent molecular mass of 15 kDa and contains 7 iron atoms/molecule. The N-terminal sequence shows a large similarity (70% identity) with that of the ferredoxin isolated from the archaeon Sulfolobus acidocaldarius. The EPR characteristics in both the native (oxidized) and dithionite-reduced states of this protein allowed an unequivocal identification of a [3Fe-4S]1+/0 center, with a reduction potential of -270 +/- 20 mV, at pH 7.5. The protein also contains a [4Fe-4S]2+/1+ center with a very low reduction potential (Eo = -540 mV, pH 7.0), which yields a rhombic EPR spectrum upon reduction with sodium dithionite at high pH. The reduction potentials of both centers are slightly pH dependent between pH 6 and 9. The [3Fe-4S] ferredoxin center is able to accept electrons from pyruvate oxidase and NADH oxidase isolated from D. ambivalens. This ferredoxin is present in large amounts (at least 130 mg/kg wet cells), which allowed the unequivocal observation of oxidized [3Fe-4S] clusters in intact D. ambivalens cells.

Abstract
1. In a multicenter, placebo-controlled, double-blind clinical trial in 155 elderly patients with cognitive decline, glycosaminoglycan polysulfate was found to be a therapeutically effective agent in the treatment of old age dementias. 2. Treatment with glycosaminoglycan polysulfate in the daily dosage of 600 LRU, administered on the basis of a divided dosage schedule for 12 weeks, was significantly superior to an inactive placebo on several outcome measures including the Wechsler Memory Scale-Russell Revision (Easy Paired Associates Learning and Immediate Visual Reproduction), Mini Mental State Examination, the Sandoz Clinical Assessment Geriatric (Cognitive Dysfunction and Depression), Hachinski Dementia Scale, Brief Psychiatric Rating Scale (Confusion and Depressive Withdrawal) and Global Improvement Scale of the Clinical Global Impression. 3. Adverse effects with glycosaminoglycan polysulfate were few and mild. The drug was equally well tolerated and equally effective in the two major dementias of old age, i.e., primary degenerative and multi-infarct. The number of abnormal laboratory test readings remained essentially unchanged from pre-treatment to post-treatment.
