AbstractInhaltsübersicht. Es wird über die Komplexbildung zwischen Ionen der 3d‐Elemente und Bis[β‐pyridyl(2)‐äthyl]‐sulfid (3, 3‐py2S‐tri) und [Pyridyl(2)‐methyl]‐[β‐pyridyl(2)‐äthyl]‐sulfid (2, 3‐py2S‐tri) in wäßriger Lösung berichtet. 2, 3‐py2S‐tri bildet mit Kupfer(ii)‐ und Nickel(ii) 1, 1‐ nnd 1,2‐Komplexe, in denen es als dreizähliger Ligand fungiert. In den Komplexen M(2,3‐py2S‐tri‐H)3+ (M = Cu(II) oder Nickel(ii)) besetzen die Liganden 2,3‐py2S‐tri‐H+'zwei Koordinationsstellen und bilden Chelatfünfringe aus. Bei dem Liganden 3,3‐py2S‐tri konnten normale und protonierte 1,1‐Komplexe, im Falle des Kupfer(II) auch ein 1,2‐Komplex nachgewiesen werden. Für eine Komplexbildung zwischen Kobalt(ii) oder Zink(ii) und 2,3‐py2S‐tri oder 3,3‐py2S‐tri ergaben sich keine Hinweise. Aus sterischen Gründen sind die Komplexe des stärker basischen Liganden 3,3‐py2S‐tri instabiler als die des 2,3‐py2S‐tri.The Influence of Ring Size on the Structure of Metal Chelates with Tridentate Ligands. II. Stability Measurements of 3d‐Metal Chelates with Pyridyl Substituted Dialkyl SulfidesAbstract. The complex formation between ions of the 3d‐elements and bis[β‐pyridyl(2)‐ethy)]‐sulfide (3,3‐py2S‐tri) and [pyridyl(2)‐methyl]‐[β‐pyridyl(2)‐ethyl]‐sulfide (2,3‐py2S‐tri) was investigated in aqueous solution. 2,3‐py2S‐tri forms 1,1‐ und 1,2‐complexes with copper(II) and nickel(ii) acting as a tridentate ligand. In the complexes M(2,3‐py2S‐tri‐H)3+ (M = Cu(ii) or Ni(ii)) the ligand 2,3‐py2S‐tri‐H+ is bidentate forming a five‐membered chelate ring. With the ligand 3,3‐py2S‐tri normal and protonated 1,1‐complexes were detected, in the case of copper(ii) also a 1,2‐complex. No complex formation was observed between cobalt(ii) or zinc(ii) and 2,3‐py2S‐tri or 3,3‐py2S‐tri. From steric reasons the complexes of the higher basic ligand 3,3‐py2S‐tri are more instable than the those of the ligand 2,3‐py2S‐tri.

Published: April 2011

AbstractInhaltsübersicht. Chelite fungieren im hinreichend sauren Milieu als schwach basische bzw. sehr schwach basische Anionenaustauscher. Sie ergänzen damit die Reihe der bekannten Anionite mit pK′B‐Werten von 10 bis 14. Sehr schwach basische Anionen, u. a. Perchlorat, Perrhenat, Chromat und Jodid, werden mit hoher Selektivität gebunden. Von Interesse ist, daß diese Anionen bereits durch Ammoniak‐Lösung schnell und quantitativ desorbiert werden. In entsprechenden Abtrennungsversuchen konnten Jodid, Chromat und Perrhenat bis in den Spurenbereich quantitativ abgetrennt werden, wobei die Perrhenat‐Abtrennung bis zum halbtechnischen Verfahren ausgearbeitet werden konnte.Investigations on the Ability of Chelite‐forming Ion Exchangers for Anion ExchangeAbstract. Chelites act as slightly basic or very slightly basic anion exchangers in a sufficiently acid medium. Thus they add to the series of known anionites with pK′Bvalues ranging from 10 to 14. Very slightly basic anions like Perchlorate, perrhenate, Chromate, and iodide are adsorbed with high selectivity. It is of interest that these anions are most readily and quantitatively desorbed by ammonia solution. It has been possible to separate iodide, Chromate, and perrhenate quantitatively up to the range of traces, whereby the perrhenate separation has been worked out to the semi‐technological process.

AbstractBackgroudHunter disease is a rare X‐linked mucopolysaccharidosis. Despite frequent neurological involvement, characterizing the severe phenotype, neuroimaging studies are scarce.ObjectivesTo determine frequency and severity of neuroradiological mucopolysaccharidosis‐related features; to correlate them with clinical phenotype; to evaluate their natural evolution and the impact of intravenous enzymatic replacement therapy (ERT).MethodsSixty nine brain MRI examinations of 36 Italian patients (mean‐age 10.4 years; age‐range 2.2‐30.8; severe phenotype in 22 patients) were evaluated. Twenty patients had multiple MRIs (median follow‐up 3.1 years, range 1–16.9): among them 15 had MRIs before and after ERT, six had repeated MRIs without being on ERT and five while on ERT. Perivascular, subarachnoid and ventricle space enlargement, white matter abnormality (WMA) burden, pituitary sella/skull/posterior fossa abnormalities, periodontoid thickening, spinal stenosis, dens hypoplasia, myelopathy, vertebral and intervertebral disc abnormalities were graded by means of dedicated scales.ResultsPerivascular spaces enlargement (89%), WMAs (97%), subarachnoid space enlargement (83%), IIIrd‐ventricle dilatation (100%), pituitary sella abnormalities (80%), cranial hyperostosis (19%), craniosynostosis (19%), enlarged cisterna magna (39%), dens hypoplasia (66%), periodontoid thickening (94%), spinal stenosis (46%), platyspondylia (84%) and disc abnormalities (79%) were frequently detected. WMAs, IIIrd‐ventricle dilatation and hyperostosis correlated with the severe phenotype (p < 0.05). Subarachnoid spaces and ventricle enlargement, WMAs and spinal stenosis progressed despite ERT, while other MR features showed minimal or no changes.ConclusionsThe spectrum of brain and spine MRI abnormalities in Hunter disease is extremely wide and requires a thorough evaluation. WMAs, atrophy/communicating hydrocephalus and spinal stenosis progress over time and might represent possible disease severity markers for new treatment efficacy assessment.
Shock, Adjust, Decide: Reproductive Decision Making in Cystic Fibrosis (CF) Carrier Couples—A Qualitative Study

Published: April 2011

AbstractCystic fibrosis (CF) is the most common recessive condition affecting the White British population. Facilitating reproductive decision making for couples at genetic risk for CF is an important aspect of genetic counseling practice in the UK. The purpose of this study was to explore the reproductive decision making process for 31 members of CF carrier couples (15 men and 16 women) with or without an affected child. The design involved a qualitative approach consisting of semi‐structured interviews and data analysis informed by grounded theory methodology. Sex and personal experience of CF were identified as factors that may influence reproductive decision making. Findings suggest these hypotheses: (1) CF carrier couples who have an affected child/pregnancy, are more likely to embark on another pregnancy than couples who have a healthy child from an at‐risk pregnancy, and (2) men and women play different roles in the reproductive decision making process. Data analysis resulted in development of a structured framework modeling the reproductive decision making process, which may be helpful in guiding genetic counseling with CF carrier couples and other at risk couples making reproductive decisions.

Published: April 2011

AbstractIsoelectric precipitation and whey nanofiltration were evaluated in recovering protein from skim fractions produced by enzyme‐assisted aqueous extraction processing (EAEP) of extruded full‐fat soybean flakes. Countercurrent two‐stage EAEP was performed at 1:6 solids‐to‐liquid ratio, 50 °C, pH 9.0, and 120 rpm for 1 h to extract oil and protein from soybeans. Two protein recovery strategies were applied to skim fractions produced by different extraction treatments: Treatment 1 using 0.5% protease (wt/g extruded flakes) in both extraction stages; Treatment 2 using 0.5% protease only in the 2nd extraction stage; and Treatment 3 using no enzyme in either extraction stage. Protein recovery by using isoelectric precipitation was inversely related to the extent of hydrolysis with recoveries of 27, 61, and 87% of skim proteins from Treatments 1, 2, and 3, respectively. Overall protein recoveries of 26, 54, and 57% of the original protein in the extruded full‐fat flakes were achieved when combining extraction treatments and isoelectric precipitation. Nanofiltering isoelectric wheys (500‐Da membrane) achieved protein retentate yields of 96.3, 94.5, and 91.8% (1.9–2.8 concentration factor) with permeate fluxes up to 1.35 kg/h m2. About 97, 98, and 99% of skim protein were recovered by isoelectric precipitation and whey nanofiltration for Treatments 1, 2, and 3, respectively. Overall protein recoveries of 93, 87, and 65% of the protein in the extruded flakes were achieved for Treatments 1, 2, and 3, respectively. Although high protein retentions were achieved, very low permeate fluxes were observed for whey nanofiltration.
Influence of Polydimethylsiloxane on the Formation of 4‐Hydroxynonenal in Soybean Oil at Frying Temperature
Authors: Gerde Jose A. , Hammond Earl G. , White Pamela J. 
Published: April 2011

AbstractSoybean oils treated with 25 or 100 ppb polydimethylsiloxane (PDMS) and a control with no PDMS were heated at 180 °C for 48 h. The decomposition of linoleate and tocopherols was monitored, as well as the changes in concentration of 4‐hydroxynonenal (HNE). HNE was rapidly formed at the beginning of the heating period in the control and in the oil containing 25 ppb PDMS. HNE reached a maximum concentration of 0.033 μmol/g oil and then began to slowly decline. The maximum HNE concentration was attained at 18 h in the control oil compared with 28 h in the oil with 25‐ppb PDMS. In the oil with 100‐ppb PDMS the HNE increased very slowly during the first 32 h after which the HNE increased faster, reaching 0.033 μmol/g oil at 46 h and showed no decline during the 48 h heating period. Thus, PDMS had a beneficial effect in preventing the formation of the toxic HNE.

AbstractObjectiveTo describe the success rate of and the quality of life after global endometrial ablation in an obese population.MethodsA follow‐up survey was mailed to 72 women who had undergone global endometrial ablation. The survey included a menorrhagia‐specific NovaSure endometrial ablation questionnaire. The mean follow‐up time was 2.5 years.ResultsForty‐four women (61%) responded, with a mean body mass index (BMI, calculated as weight in kilograms divided by the square of height in meters) of 30.5. Overall, patients reported a decrease in missed social activities, in inability to perform activities of daily living, in missed work days, in bleeding tendencies, and in pain. The amenorrhea rate was 37%, and the success rate (those not requiring any further therapeutic treatment) was 86%. Patient satisfaction was 93%.ConclusionGlobal endometrial ablation improved quality of life for obese women with menorrhagia and had a high rate of satisfaction, even for patients not achieving amenorrhea. Patients with a BMI of more than 34 showed a trend toward failure and a higher rate of hysterectomy.

Published: April 2011

AbstractObjectiveTo evaluate the feasibility and effectiveness of using TachoSil during obstetric and gynecologic surgery.MethodsThe retrospective cohort study, conducted at a French university hospital, included women who experienced perioperative bleeding requiring the use of TachoSil during 2007–2009. The following information was collected: patient age, indication for the use of TachoSil, need for a blood transfusion, type of surgery performed, postoperative course, and traceability of TachoSil.ResultsTachoSil was used in 84 women. The main indications for the surgical interventions requiring TachoSil were ovarian malignancy (n = 18), fibroma (n = 17), breast cancer (n = 11), and endometrial cancer (n = 10). In 16 women, TachoSil was applied to the uterine serosa, particularly after cesarean delivery or polymyomectomy; in 7 women, it was applied to the major vascular axis. Red cell packs were infused in 24 women during surgery (average 3 packs per woman). Three women required repeat surgery. The use of TachoSil was not recorded in the operative reports of 43 (51%) women.ConclusionThe present findings confirm that the use of TachoSil in gynecologic and obstetric surgeries is effective and well tolerated. Measures to improve the traceability of TachoSil use are recommended.

Published: April 2011

AbstractObjectiveTo compare the efficacies of oral naproxen and oral tramadol for pain relief after cesarean delivery, and to evaluate administration at fixed intervals versus on request.MethodsIn a prospective study, 120 women were randomized into 4 groups receiving either oral naproxen or oral tramadol at fixed intervals or on request. Pain was assessed at 6, 12, 24, and 48 hours after delivery, and adverse effects, mobility, breastfeeding, and the need for additional drugs for breakthrough pain were recorded.ResultsNo difference in pain scores was observed at 6, 12, 24, or 48 hours among the 4 groups, between the 2 drugs, or between the 2 methods of administration. Women randomized to receive oral tramadol requested additional drugs for breakthrough pain more frequently. In addition, adverse effects were twice as common in the tramadol group as in the naproxen group, and more women in the tramadol group abandoned the study.ConclusionAlthough similar in terms of pain scores, oral naproxen might be more effective than oral tramadol for pain relief after cesarean delivery. Naproxen seemed to have a better adverse‐effects profile, and therefore might be more suitable for mothers. Administration at fixed intervals might be more efficacious than administration on request.
DEVELOPING PREDICTION EQUATIONS AND OPTIMIZING PRODUCTION OF THREE AM FUNGAL INOCULA UNDER ON-FARM CONDITIONS
Authors: SHARMA MAHAVEER P. , ADHOLEYA ALOK 
Published: April 2011

SUMMARYThe production potential of three arbuscular mycorrhizal fungi (AMF), AM-1004 (Glomus intraradices), AM-1209 (mixed indigenous AMF) and AM-1207 (Mycorise, commercial inocula), were examined separately in three fractions/forms (root-based, soil-based and mixture of roots + soil) at 40, 60, 80 and 105 days in raised beds. The beds were amended with organic matter to develop regression equations for predicting optimal AM production vis-à-vis time required for particular inocula using infectious propagules (IP) as the independent variable. The IP production observed in the system was found to vary among the different inocula used. AM-1004 and AM-1207 produced significantly higher propagule counts in root or soil-based samples and a mixture of both at 105 days as compared to AM-1209. Based on two-way ANOVA, irrespective of time, AM-1004 (root/soil-based) produced a significantly larger number of propagules, whereas propagules in the crude inoculum (roots + soil) of all three inocula were not significantly different. On the other hand, irrespective of AMF, significantly more propagules (in all forms) were observed at 105 days. Similarly, irrespective of time, AM-1004 produced significantly higher root colonization (MCP, mycorrhizal colonization percentage) in all three forms (roots: 65.95%; soil: 24.32; soil + roots: 58.03%). The MCP in roots was increased significantly with time of multiplication. However, there was not much improvement in the MCP of soil or in soil + roots fractions beyond 80 days. Further, prediction of the number of IP for the three AM inocula was mathematically derived separately from the Mitscherlish-Bray equation (Y=a–b*exp (–cD). Based on the maximum yield of propagules of the three inocula observed and fitted into equations, root-based AM-1004 and AM-1209 inocula were found to be more efficient in producing propagules in 65 days as compared to AM-1207, which produced propagules in 76 days. While comparing the overall combinations, AM-1004 and AM-1209 inocula used either as roots, soil or a mixture of both and have greater potential in producing more propagules in the shortest span of time. While taking into account the predicted values of AM-1209 crude inoculum, about 12 IP g−1substrate can be achieved in 72 days. Therefore, if a farmer uses crude inocula (having zero time IP of about 0.8/g substrate) of AM 1209, a total production of about 12.12 million IP/m3can be achieved in 72 days. These can be used for on-farm production.

Published: April 2011

AbstractThis study was conducted in order to investigate the epidemiology of filarial species in a region of central Italy (Tuscany) in dogs that did not undergo prophylaxis for filariasis. From 2007 to 2009, 630 blood samples were collected from 40 kennels throughout the regional territory. Samples were analysed with Knott's modified test and with an enzyme-linked immunosorbent assay (ELISA) for the detection of Dirofilaria immitis antigens, those positive for microfilariae were also subjected to histochemical staining for acid phosphatase activity to validate the identification of the species. An overall elevated prevalence of filariasis (23.2%) was found. Dirofilaria immitis and D. repens were found to be the dominant species, with similar prevalences (12.5% and 12.1% respectively), while Acanthocheilonema reconditum was less common (1.9%). Results of this study indicate that monitoring for filariasis should be kept at a high level. A constant monitoring of the canine sanitary status should also be carried out for the protection of human health, considering the zoonotic potential of filarial worms.
Free Association and Civil Society in Cuba, 1787–1895
Authors: QUIROZ ALFONSO W. 
Published: April 2011

AbstractThis study provides a new perspective on civil society in Cuba during the nineteenth century based on concrete information about multiple types of association in different regions of the island. Modern associations developed mainly to meet specific social and cultural needs, achieve legal autonomy from the state and exercise free association despite colonial constraints. This long-term evolution covers several periods of intersections between civil society and political spheres, framed primarily by non-violent constitutionalist and reformist struggles rather than armed separatist conflicts. These findings contradict prevalent interpretations that portray an endemically weak yet increasingly militant civil society. Instead, a growing, moderate, and progressively autonomous and diverse civil society contributed gradually to undermine colonial despotism and establish key bases for post-independence democracy.
The Production of Autonomy: Leadership and Community in Mayan Guatemala
Authors: EKERN STENER 
Published: April 2011

AbstractThe Mayan Indians of Guatemala share the burdens of local government by taking on a set of public duties, thereby maintaining community cohesion as well as political autonomy. This article analyses recent changes in thiscargosystem in a context defined by development, new representations of ‘Mayanness’, and multicultural politics. It shows how sovereignty – grounded in a distinct philosophy of leadership that generates meaningful self-rule – is crucial in facilitating political transformation towards more democratic arrangements at the cost of rule by the elders.
Phr1 is required for proper retinocollicular targeting of nasal–dorsal retinal ganglion cells
Authors: VO BRADLY Q. , BLOOM A. JOSEPH , CULICAN SUSAN M. 
Published: April 2011

AbstractPrecise targeting of retinal projections is required for the normal development of topographic maps in the mammalian primary visual system. During development, retinal axons project to and occupy topographically appropriate positions in the dorsal lateral geniculate nucleus (dLGN) and superior colliculus (SC). Phr1 retinal mutant mice, which display mislocalization of the ipsilateral retinogeniculate projection independent of activity and ephrin-A signaling, were found to have a more global disruption of topographic specificity of retinofugal inputs. The retinocollicular projection lacks local refinement of terminal zones and multiple ectopic termination zones originate from the dorsal–nasal (DN) retinal quadrant. Similarly, in the dLGN, the inputs originating from the contralateral DN retina are poorly refined in the Phr1 mutant. These results show that Phr1 is an essential regulator of retinal ganglion cell projection during both dLGN and SC topographic map development.
