The Rehabilitation of a Traumatic Brain Injury With the Coordinated Allocation of Resource Model
Authors: Thornton Kirtley 
Published: December 2010

Abstract
A case analysis of a person with a traumatic brain injury (TBI) is presented in detail. The analysis employs the coordination allocation of resource (CAR) model of brain functioning and the activation quantitative EEG analysis of brain response patterns. This model states that individual cognitive tasks involve specific frequencies and locations for successful performance and employs a flashlight metaphor for conceptualization of spectral correlation coefficient relationships between locations. The employment of this model in this specific case resulted in dramatic improvements in auditory memory (+5.4 standard deviations) as well as other improvements in cognitive functioning, albeit not all cognitive functioning skills.

Depression, Love, Happiness, and the Quantitative Electroencephalography in a Single Case Study
Authors: Thornton Kirtley E. , Carmody Dennis P. 
Published: December 2010

Abstract
The relations between the emotions and the brain's functioning have been the subject of scientific investigation over the past decade. This report continues this investigation in a single case study that required the subject to evoke different emotional states (happiness, love, depression) and rate the emotional states on an intensity scale while brain activity was monitored by quantitative electroencephalography (QEEG). The variations in brain activation patterns in these evoked emotional states indicated a predominant QEEQ activation of the beta2 (32–64 Hz) frequency range for all emotional states, with specificity of left hemisphere and temporal lobe activation for happiness and right hemisphere for depression. The response pattern also indicated a greater activation of central and posterior locations for the emotional states.

Static Surface Electromyography and Neuromuscular Reeducation
Authors: Sella Gabriel E. 
Published: December 2010

Abstract
Static surface electromyography can provide an objective test of the cervical, thoracic, and lumbar posterior areas that needs to be performed within a clear clinical or ergonomic context. It is of great help in postural assessment in the standing position in people with healthy backs or postural dysfunctions. The author has devised a protocol that allows statistically based treatment and more valid clinical interpretation. Most often, static surface electromyography is a necessary precursor to dynamic surface electromyography of any area of clinical concern. When appropriate, neuromuscular reeducation with surface electromyography biofeedback can be performed to improve resting tonus dysfunctions observed on the static surface electromyography testing.

SummaryAcquired von Willebrand’s disease (aVWD) is considered to be an underestimated cause of unexplained bleeding. Adsorption of von Willebrand factor (VWF) to tumour cells or hydroxyethyl starch and elimination of VWF by autoantibodies as well as shear stress-induced mechanical alteration of VWF with concomitant cleavage by enzymes may lead to an acquired deficiency of VWF and a bleeding disorder.We report a 39-year-old woman who developed spontaneous bleeding five years after surgical creation of an arteriovenous fistula (AVF) for haemodialysis treatment. AVWD type 2A was diagnosed after successful renal transplantation. One year after surgical closure of the AVF, the aVWD could not be verified again. Thus, the aVWD may have developed because of altered blood flow and shear stress inside the arteriovenous fistula.
Bewertung des Rezidivthrombose-risikos venöser Thromboembolien
Authors: Lindhoff-Last E. 
Published: December 2010

SummaryRecurrent venous thromboembolism is associated with increased mortality in 5–9% of the patients. On the other hand prolonged anticoagulation can increase the bleeding risk which can also be responsible for an increased mortality. Therefore, it is necessary to validate the recurrence risk of venous thromboembolism on an individual basis.In this review the most relevant risk factors for recurrent venous thromboembolism are analyzed. Spontaneous thrombosis is associated with significantly increased recurrence rates in comparison to risk associated venous thrombosis. In addition, a positive D-dimer result after stop of anticoagulation, an increased amount of residual thrombus in proximal veins analyzed by compression sonography, a proximal localization of thrombosis, symptomatic pulmonary embolism and male sex are clinically relevant risk factors for increased recurrence rates. While mild thrombophilic defects like heterozygous factor V Leiden mutation are not associated with a clinically relevant recurrence risk, inherited inhibitor deficiencies and the anti-phospholipid-syndrome are known to be responsible for an increased recurrence rate of venous thromboembolism. A new recurrence risk-score (RR-Score) for individual judgement of patients with a first spontaneous venous thrombosis is introduced.

Authors: Enders Dieter , Gottfried Katharina , Raabe Gerhard 
Published: December 2010

AbstractThe first organocatalytic enantioselective Strecker synthesis of α‐quaternary α‐trifluoromethylated amino acids has been developed. Employing Takemoto’s thiourea catalyst the nucleophilic addition of trimethylsilyl cyanide to trifluoromethyl ketimines affords α‐amino nitriles in good to excellent yields (50–99%) and very good enantioselectivities (ee=83–95%). The enantiopure amino nitriles can be obtained by recrystallization. Deprotection and hydrolysis leads to the title amino acids.
(Cyclopentadienyl)ruthenium‐Catalyzed Regio‐ and Enantioselective Decarboxylative Allylic Etherification of Allyl Aryl and Alkyl Carbonates
Authors: Austeri Martina , Linder David , Lacour Jérôme 
Published: December 2010

Abstract(Cyclopentadienyl)tris(acetonitrile)ruthenium hexafluorophosphate {[CpRu(NCMe)3][PF6]} or (cyclopentadienyl)(η6‐naphthalene)ruthenium hexafluorophosphate {[CpRu(η6‐naphthalene)][PF6]} in combination with a pyridine oxazoline ligand efficiently catalyze the decarboxylative allylic rearrangement of allyl aryl carbonates. Good levels of regio‐ and enantioselectivity are obtained. Starting from enantioenriched secondary carbonates, the reaction is stereospecific and the corresponding allylic ethers are obtained with net retention of configuration. An intermolecular version of this transformation was also developed using allyl alkyl carbonates as substrates. Conditions were found to obtain the corresponding products with similar selectivity as in the intramolecular process. Through the use of a hemi‐labile hexacoordinated phosphate counterion, a zwitterionic air‐ and moisture‐stable chiral ruthenium complex was synthesized and used in the enantioselective etherification reactions. This highly lipophilic metal complex can be recovered and efficiently reused in subsequent catalysis runs.

Published: December 2010

AbstractTwo different combinations of coupling partners can be employed for the synthesis of conjugated dienes by palladium‐catalyzed cross‐coupling with tosylhydrazones: α,β‐unsaturated ketone and aryl halide or alkenyl halide and non‐conjugated tosylhydrazone. Depending on the substrate, a vinylogous hydride elimination is responsible for the formation of the final dienes.

AbstractEstrogen modulates pain perception but how it does so is not fully understood. The aim of this study was to determine if estradiol reduces nociceptive responses in part via hypothalamic‐pituitary‐adrenal (HPA) axis regulation of cyclooxygenase (COX)‐1/COX‐2 activity. The first study examined the effects of estradiol (20%) or vehicle with concurrent injection nonsteroidal antiinflammatory drugs (NSAIDs) on formalin‐induced nociceptive responding (flinching) in ovariectomized (OVX) rats. The drugs were ibuprofen (COX‐1 and COX‐2 inhibitor), SC560 (COX‐1 inhibitor), or NS398 (COX‐2 inhibitor). In a second study, estradiol's effects on formalin‐induced nociception were tested in adrenalectomized (ADX), OVX, and ADX+OVX rats. Serum levels of prostaglandins (PG) PGE2 and corticosterone were measured. Estradiol significantly decreased nociceptive responses in OVX rats with effects during both the first and the second phase of the formalin test. The nonsteroidal antiinflammatory drugs (NSAIDs) did not alter nociception at the doses used here. Adrenalectomy neither altered flinching responses in female rats nor reversed estradiol‐induced antinociceptive responses. Estradiol alone had no effect on corticosterone (CORT) or prostaglandin levels after the formalin test, dissociating the effects of estradiol on behavior and these serum markers. Ibuprofen and NS398 significantly reduced PGE2 levels. CORT was not decreased by OVX surgery or by estradiol below that of ADX. Only IBU significantly increased corticosterone levels. Taken together, our results suggest that estradiol‐induced antinociception in female rats is independent of COX activity and HPA axis activation. Synapse, 2011. © 2010 Wiley‐Liss, Inc.

AbstractA series of microPET imaging studies were conducted in anesthetized rhesus monkeys using the dopamine D3‐selective partial agonist, [18F]5. There was variable uptake in regions of brain known to express a high density of D3receptors under baseline conditions. Pretreatment with lorazepam (1 mg/kg, i.v. 30 min) to reduce endogenous dopamine activity before tracer injection resulted in a dramatic increase in uptake in the caudate, putamen, and thalamus, and an increase in the binding potential (BP) values, a measure of D3receptor binding in vivo. These data indicate that there is a high level of competition between [18F]5and endogenous dopamine for D3receptors in vivo. Synapse 2011. © 2011 Wiley‐Liss, Inc.

Authors: Sidim Taliha , Arda Meltem 
Published: December 2010

AbstractMixed surfactant solutions consisting of cationic/nonionic surfactants were prepared in different compositions of the components in aqueous solution in order to determine the surface properties. The critical micelle concentration (CMC) of aqueous solutions of the individual surfactants cetyl trimethyl ammonium bromide (CTAB) and polysorbate nonionics, and their mixtures are determined at different proportions. The results show that there is synergistic behavior in mixtures at higher mole fraction of nonionic surfactant. The effect of the alkyl chain on the CMC is also determined.
The effect of delayed onset of muscle soreness on habitual trapezius activity

Published: December 2010

AbstractThe aim of the study was to investigate the effect of acute trapezius pain, induced by delayed onset of muscle soreness (DOMS), on habitual trapezius activity. Long‐term (5 h) surface electromyographic (sEMG) activity was recorded bilaterally from the clavicular, descending, transverse, and ascending trapezius on two consecutive weekdays in eleven female subjects (mean age 22 years, range 20–24 years). Body and arm posture were recorded by inclinometers. Immediately after the first long‐term recording, the subjects performed eccentric depression exercise of the left shoulder to induce DOMS. From day 1 to day 2, pressure pain threshold (PPT) decreased and pain scores on visual analog scale (VAS) increased for the left upper trapezius (P <.004 for all comparisons). Habitual sEMG activity (median sEMG level, μV) of the clavicular and descending part of the exercised left trapezius increased from first to second long‐term recording during periods with seated posture (P <.05 for both comparisons). In contrast, trapezius sEMG activity remained unchanged for all other trapezius parts and postures. This study indicates that acute trapezius pain induces elevated habitual trapezius activity during periods with low biomechanical loading of the shoulder/neck muscles with the elevated sEMG activity being restricted to the painful part of the muscle. In contrast to the pain‐adaption model, the current study indicates a relation between acute muscle pain and elevated low‐level muscle activity; however, it remains unknown if development of chronic muscle pain can be preceded by an initial stage with elevated muscle activity.

AbstractObjectivesQuantitative EEG can monitor changes in brain function during development and may help to understand developmental disorders. However, current EEG‐databases are primarily based on standardized frequency bands which disregard age‐related changes in alpha peak frequency (PF) and therefore complicate the interpretation of spectral estimates in the theta and alpha range.MethodsWe used a two point longitudinal design in order to analyze intraindividual changes in 40 healthy children and adolescents with age (T1: 6–18 years; interval approximately 4 years). Using a 64‐channel eyes closed resting EEG we calculated absolute/relative power in individualized frequency bands (IFB: delta, theta, alpha1/2 and beta) based on PF.ResultsPF increased with age, with changes being larger for children than adolescents. Controlling for changes in PF, changes in absolute/relative alpha1/2 power and in absolute beta power were minor. Relative beta power, however, increased while absolute/relative delta and theta power decreased massively.Sex‐differences in PF did not reach significance. However, boys exhibited larger changes during adolescence than girls for all absolute power measures except alpha.ConclusionNormal EEG development during school‐age is mainly based on an absolute decrease of slow frequency activity and increases of PF which may be interpreted in terms of a reorganization of the EEG towards a higher frequency oscillatory scale rather than a maturation of the theta–alpha1/2 band power sequence. Age‐related changes differed between boys and girls suggesting a different developmental timing for the sexes. In future studies a combined analysis of PF and IFB may help to specify deviations in developmental disorders.

AbstractObjectiveTo evaluate the reported occurrence of spontaneous and induced abortion, and abortion‐associated severe maternal morbidity in Brazil.MethodsA secondary analysis of the 2006 Brazilian Demographic Health Survey was conducted. Interview data on women's experience of spontaneous/induced abortion and associated factors were analyzed overall and by geographic region. Multinomial logistic regression was performed to identify factors independently associated with abortion. The risk of associated severe maternal morbidity was estimated.ResultsThe reported lifetime rates of spontaneous and induced abortion were 13.3% and 2.3%, respectively, and were highest in the north (4.3%) and northeast (3.5%). The rate of spontaneous abortion was higher among women aged 40–49 years (odds ratio [OR] 1.15; 95% confidence interval [CI], 1.03–1.30) and among those with 0 or 1 children or delivery (OR 1.97; 95% CI, 1.36–2.85 vs OR 1.98; 95% CI, 1.37–2.86). Induced abortion was not associated with sociodemographic factors. Abortion significantly increased the risk of complications (hemorrhage and infection).ConclusionSpontaneous abortion was significantly associated with parity and maternal age. Abortion in general carried a higher risk of severe maternal complications.

AbstractObjectiveTo determine the incidence of covert and overt postpartum urinary retention (PUR) after vaginal delivery and to determine obstetric variables contributing to PUR.MethodsIn a cross‐sectional study, women who delivered vaginally underwent a transabdominal ultrasound scan for estimation of postvoid residual bladder volume and diagnosis of PUR. Patient data, including age, obstetric history, mode of delivery, and duration of labor, were compared between women with and those without PUR.ResultsOf the 771 participants recruited, 84 (10. 9%) had PUR: 82 (10.6%) with covert PUR and 2 (0.3%) with overt PUR. Women with instrumental delivery were more prone to develop PUR (P = 0.03), with an odds ratio (OR) of 1.194 (95% confidence interval [CI], 0.56–1.90). A duration of labor of more than 700 minutes was a good predictor of PUR. The area under the receiver operating characteristic (ROC) curve was 0.634 (95% CI, 0.567–0.702; P < 0.001), with an OR of 1.003 (95% CI, 1.001–1.004).ConclusionCovert retention of urine was significantly associated with parturients who had an instrumental delivery and a duration of labor of more than 700 minutes.
