Dipyridamole scintigraphy and intravascular ultrasound after successful coronary intervention.

UNLABELLED Despite angiographically successful interventions, perfusion defects are not uncommonly observed in postinterventional perfusion scintigrams. The aim of this study was to test the hypothesis that perfusion defects after coronary intervention are associated with a significant residual stenosis in the treated vessel segment detectable by intravascular ultrasound but not by angiography. METHODS Forty consecutive patients with angiographically successful coronary interventions were prospectively studied by intravascular ultrasound immediately after the intervention. Within 48 hr after the intervention all patients had myocardial scintigraphy using 99mTc-methoxyisobutyl-isonitrile SPECT after dipyridamole stress. Myocardial perfusion defects in the scintigram were assigned to a segmental left ventricular model and compared to the perfusion territory of the treated vessel estimated from the coronary angiogram. RESULTS Twenty of 40 patients had reversible myocardial perfusion defects. Mean ultrasound area stenosis was 50% in these patients and 33% in patients without perfusion defects (p < 0.002); ultrasound percent plaque area was 75% versus 63% (p < 0.0001), respectively. The best concordance between residual area stenosis and perfusion defects was found for an ultrasound area stenosis > or = 40%. CONCLUSION Patients with stress-induced myocardial perfusion defects immediately after successful coronary intervention show high-grade residual stenoses that are more pronounced in patients with perfusion defects than in patients with normal postinterventional scintigrams. In addition, vessels serving myocardial regions with perfusion defects showed a significantly higher plaque burden indicating diffuse atherosclerotic changes in the vessel. The evaluation of the postprocedural result by intravascular ultrasound contributes to a better understanding of the discrepancy between the angiographic finding of a widely patent vessel but scintigraphic evidence of impaired perfusion.
Crystal structure of oryzalin

The title compound, C12H18N4O6S (systematic name: 4-dipropylamino-3,5-dinitrobenzenesulfonamide), is a sulfonamide with herbicidal properties marketed as oryzalin. The dihedral angles between the benzene ring and the mean planes of the nitro groups are 26.15 (11) and 54.80 (9)°. The propyl arms of the dipropylamino substituent lie on opposite sides of this ring plane. In the crystal, N—H⋯O and C—H⋯O hydrogen bonds generate a three-dimensional network.
Poorly Ordered Bone as an Endogenous Scaffold for the Deposition of Highly Oriented Lamellar Tissue in Rapidly Growing Ovine Bone

The mechanical properties of bone are known to depend on its structure at all length scales. In large animals, such as sheep, cortical bone grows very quickly and it is known that this occurs in 2 stages whereby a poorly ordered (mostly woven) bone structure is initially deposited and later augmented and partially replaced by parallel fibered and lamellar bone with much improved mechanical properties, often called primary osteons. Most interestingly, a similar sequence of events has also recently been observed during callus formation in a sheep osteotomy model. This has prompted the idea that fast intramembranous bone formation requires an intermediate step where bone with a lower degree of collagen orientation is deposited first as a substrate for osteoblasts to coordinate the synthesis of lamellar tissue. Since some osteoblasts become embedded in the mineralizing collagen matrix which they synthesize, the resulting osteocyte network is a direct image of the location of osteoblasts during bone formation. Using 3-dimensional imaging of osteocyte networks as well as tissue characterization by polarized light microscopy and backscattered electron imaging, we revisit the structure of growing plexiform (fibrolamellar) bone and callus in sheep. We show that bone deposited initially is based on osteocytes without spatial correlation and encased in poorly ordered matrix. Bone deposited on top of this has lamellar collagen orientation as well as a layered arrangement of osteocytes, both parallel to the surfaces of the initial tissue. This supports the hypothesis that the initial bone constitutes an endogenous scaffold for the subsequent deposition of parallel fibered and lamellar bone.
Do cavity‐nesting primates reduce scent marking before retirement to avoid attracting predators to sleeping sites?

The largest population of endangered golden lion tamarins (Leontopithecus rosalia, GLTs) decreased from approximately 330 to 220 individuals between 1995 and 2000 due to a dramatic increase in predation at sleeping sites. We used behavioral data from eight social groups in this population to test two hypotheses: First, if GLTs attempt to mitigate the risk of predation at sleeping sites, they should reduce their rates of scent marking just prior to retirement. Second, if the benefits of scent marking prior to entering the sleeping site merit an increase in the rate of marking, then tamarins should increase their rate of pre‐retirement scent marking during the breeding season, when such behavior would have its greatest impact on reproductive fitness. We used a generalized linear model (GLM) repeated‐measures analysis to compare rates of daytime scent marking with rates of marking just prior to retirement for males and females. In addition, we compared scent marking prior to retiring in the nonbreeding season to marking rates before retirement in the breeding season for males and both sexes considered concurrently. Contrary to our expectations, GLTs significantly increased their rates of scent marking during the 30 min prior to entering their sleeping site–an observation driven by an increase in male (but not female) rates of marking. Rates of marking before entering the sleeping site were greater in the nonbreeding season compared to the breeding season, when both sexes were considered concomitantly and when males were evaluated alone. We conclude that GLTs do not attempt to minimize predation risk by decreasing scent marking in the period before they enter their sleeping site, and that tamarins do not scent mark at this time of day in order to transmit information about reproductive status or to control reproduction of subordinates. We speculate that scent marking in the 30 min prior to entering sleeping sites may serve to reduce predation risk by enabling tamarin groups to return quickly to favored sleeping sites in the evening when crepuscular predators are active.

A Study of the Effectiveness of a Workplace Violence Intervention for Small Retail and Service Establishments

Objective:Examine the effectiveness of a robbery and violence prevention program in small businesses in Los Angeles. Methods:Gas/convenience, liquor and grocery stores, bars/restaurants, and motels were enrolled between 1997 and 2000. Intervention businesses (n = 305) were provided training, program implementation materials, and recommendations for a comprehensive security program. Control businesses (n = 96) received neither training nor program materials. Results:Rate ratios comparing intervention to control businesses were 0.90 for violent crime (95% confidence limits [CL] = 0.53, 1.53) and 0.81 for robbery (95% CL = 0.38, 1.73). The reduction in violent crime was concentrated in high-compliance intervention businesses (risk ratio = 0.74, 95% CL = 0.40, 1.36). Low-compliance intervention businesses had practically the same postintervention crime as the control businesses. Conclusions:Our results suggest that the workplace violence intervention may reduce violent crime among high-risk businesses, especially those with high program compliance.
Prevalence of Genitourinary Symptoms in the Late Menopause

Abstract. One thousand two hundred women, aged 61, randomly selected from a defined geographical area in South Sweden, were interviewed by an anonymous questionnaire about their urogenital symptoms. Seventy‐five percent cooperated, of whom 29.2% admitted to some degree of urinary incontinence and 48.8% some degree of lower genital tract disorder. Stress incontinence symptoms were reported by 11.8% of the women, urge incontinence by 7.9% and both types combined—“mixed” by 9.5%. Four percent of all women (18% of stress incontinence) experienced a loss sufficient to necessitate the wearing of a sanitary napkin or change of under clothing several times a day. Thirteen percent had repeated urinary tract infections. Itch, discharge and smarting pain was reported by 15%. Thirty‐eight percent had vaginal dryness and dyspareunia. Only 4% of the women were undergoing estrogen therapy.
High frequency battery impedance measurements for EMI prediction

In embedded applications which include power converters, the battery that provides the energy is a part of the EMI path. As conducted emissions generated by power converters spread into a large frequency band, the battery characterization should be extended to cover this range of frequencies. In this paper, a method to measure the battery impedance using an impedance analyzer is explained and applied to a cell-phone battery from 1MHz to 100 MHz. In this frequency range, measurements show that the battery impedance is unrelated to the battery state of charge and that a model including just inductances and resistances matches very well with the measured behavior. The measured impedance is validated by predicting the frequency spectrum of the battery's voltage when feeding a switched-mode power converter. The converter switches at 1.2MHz and the related harmonics extend beyond 100 MHz. The measured and predicted voltages match up to 80 MHz.
PWM- and PFM-controlled switched capacitor converter-based multiport converter integrating voltage equalizer for photovoltaic systems

Photovoltaic (PV) systems consist of multiple dc-dc converters, including a front-end converter for PV string control, a bidirectional converter for battery regulation, and voltage equalizer to preclude partial-shading issues, and hence they are prone to be complex and costly. To cope with this issue, this paper proposes the PWM- and PFM-controlled switched capacitor converter (SCC)-based multiport converter (MPC) integrating voltage equalizer. The proposed MPC can be derived by integrating a bidirectional PWM converter, series-resonant converter (SRC), and SCC. The PWM converter and SRC regulate battery and load voltages, respectively, while the SCC plays a role of the voltage equalization. Not only is the system as a whole dramatically simplified but also the circuit element count is significantly reduced thanks to the integration. The 150-W prototype for three PV modules was built for verification. The experimental results demonstrated the extractable maximum power from PV modules was significantly improved by the SCC, while the battery and load voltages were individually regulated by the PWM and PFM controls, respectively.
Race and Public Deliberation

Although deliberation has a central place in democratic theory, scholars know little about how it actually works. Most deliberative theorists emphasize the many good consequences of deliberation. By contrast, Mansbridge suggests that deliberation in certain circumstances may exacerbate conflict. Scholarship on racial politics suggests that each hypothesis is complicated by implicitly racial language. Using a quasi-experiment, we contrast the rhetoric in two town meetings about school desegregation: a segregated meeting with homogeneous interests, in which segregated Whites unanimously argued against desegregation, and an integrated meeting with heterogeneous interests, in which segregated Whites argued against integrated Whites, Hispanics, and African Americans. We find that (a) deliberation at the segregated meeting maintained consensus among segregated Whites; (b) these citizens used coded rhetoric that appeared universal, well-reasoned, and focused on the common good, but in fact advanced their group interest; (c) deliberation at the integrated meeting maintained the conflict between segregated Whites and others; and (d) there, rhetoric that seemed universal to segregated Whites was decoded by the integrated audience as racist and group interested. We highlight the problem posed by the contested meaning of language and suggest ways to make deliberation more effective.
Danish Anaesthesia Allergy Centre – preliminary results

Background: Anaphylactoid reactions in anaesthesia are rare and should ideally be investigated in specialist centres. At Gentofte University Hospital, we established such a centre in 1998 as a joint venture between the Departments of Anaesthesiology and Dermatology. We present the methodology, diagnostic algorithm and preliminary results from our centre.
Motivational Strategies, Task Effectiveness and Incidental Acquisition of Second Language Vocabulary

Current approaches to L 2 motivation view language learning motivation as situated, dynamic and task-dependent (Pawlak, 2012). Despite the widespread recognition of motivation as a crucial variable in L 2 acquisition, few studies have focused on the effect of motivational involvement of learners in an instructional setting, such as task-based language teaching context, on learning achievements. This study aimed at probing the effect of motivational strategies (Dornyei, 2001b) applied to the pre-task phase of task implementation on short-term and long-term retention and ease of activation of L 2 vocabulary acquired incidentally as a result of engagement with a reading-while listening task. Multivariate analysis of covariance (MANCOVA) revealed that motivational strategies had an enhancing effect on both retention and ease of activation of L 2 vocabulary upon the immediate post-test. However, the enhancement was not observed for long-term acquisition since there was a considerable decay of retention and ease of activation upon the delayed post-test. The results confirm the effectiveness of task-specific motivation in improving linguistic achievements. Nevertheless, it is argued that motivational strategies cannot be a single substitution for cognitive strategies.
Gabapentin for Pruritus in Palliative care

Itch/pruritus can be very distressing in palliative care population and often is difficult to treat. Conventional antihistamines lack efficacy. Cutaneous and central pathogenesis of itch is extremely complex and unclear, making its treatment challenging. Neuronal mechanisms have been identified in the pathophysiology of itch hence providing a myriad of therapeutic options. It has been established that pruritus and pain neuronal pathway interact with each other, hence neuropathic analgesics like gabapentin has shown to be efficacious antipruritic therapeutic option. Gabapentin impedes transmitting nociceptive sensations to brain, thus also suppressing pruritus. Gabapentin is safe and found to be effective in uremic pruritus, cancer/hematologic causes, opiod-induced itch, brachioradial pruritis, burns pruritus, and pruritus of unknown origin. Further research is required in this area to establish whether gabapentin is consistently effective.

Anatomy in occupational therapy program curriculum: Practitioners' perspectives

Anatomy education is undergoing significant transformation. It is unknown whether changes are in accordance with occupational therapy (OT) practice needs. The purpose of this pilot study was to survey OT clinicians to determine their perspectives on the value of anatomy in OT curricula, and anatomical knowledge required for practice. In addition to demographics, the survey asked questions on the value of a standalone anatomy course, integration of anatomical content in other coursework, practice areas requiring anatomy knowledge, course content, teaching media recommendations, and their opinions regarding whether graduates have adequate anatomy knowledge for competent practice. Surveys were distributed to OT practitioners in the state of Arizona (n = 107). Response rate was 51% on electronic surveys, 29% on mailed surveys. All respondents recommended an anatomy course in OT curricula; 97% as a standalone course with integration of course content throughout the curriculum. The most recommended teaching method was cadaver dissection. Content areas identified as important to cover included skeletal, muscular, and nervous systems. Regions recommended were the upper limb, thorax/trunk, head and neck, and lower limb. Practice areas requiring anatomy knowledge included joint range of motion and strengthening treatment interventions, goniometry, muscle strength testing, assessing muscle tone, wheelchair assessment/prescription, orthotics, physical agent modalities, and activity adaptation. Eighty‐one percent felt that entry‐level practitioners had adequate knowledge for competent practice. This study supports inclusion of a separate anatomy course in OT curricula, continued use of cadavers, and the importance of including input from practicing clinicians when determining anatomy course content.

Major non-ABO incompatibility caused by anti-Jk a in a patient before allogeneic hematopoietic stem cell transplantation

A 49-year-old white man with blood group AB, D+ was found to have alloanti-Jk(a) and -K when he developed a delayed hemolytic transfusion reaction before allogeneic hematopoietic stem cell transplant (HSCT). Given that his stem cell donor was blood group O, D+, Jk(a+), K-, rituximab was added to his conditioning regimen of fludarabine and melphalan to prevent hemolysis of engrafting Jk(a+) donor red blood cells. The patient proceeded to receive a peripheral blood stem cell transplant from a matched unrelated donor with no adverse events. To our knowledge, this is the first case of successful management of major non-ABO incompatibility caused by anti-Jk(a) in a patient receiving an allogeneic HSCT reported in the literature.
Water compartmentalization and extracellular tortuosity after osmotic changes in cerebellum of Trachemys scripta.

1. Water compartmentalization in the turtle cerebellum subject to media of different osmolalities was quantified by combining extracellular diffusion analysis with wet weight and dry weight measurements. The diffusion analysis also determined the tortuosity of the extracellular space. 2. Isolated cerebella were immersed in normal, oxygenated physiological saline (302 mosmol kg‐1), hypotonic saline (238 mosmol kg‐1) and a series of hypertonic salines (up to 668 mosmol kg‐1). The osmolality was varied by altering the NaCl content. 3. Extracellular volume fraction and tortuosity of the granular layer of the cerebellum were determined from measurements of ionophoretically induced diffusion profiles of tetramethylammonium, using ion‐selective microelectrodes. The volume fraction was 0.22 in normal saline, 0.12 in hypotonic medium and 0.60 in the most hypertonic medium. Tortuosity was 1.70 in the normal saline, 1.79 in the hypotonic and 1.50 in the most hypertonic saline. 4. The water content, defined as (wet weight‐dry weight)/wet weight, of a typical isolated cerebellum (including granular, Purkinje cell and molecular layers) was 82.9%. It increased to 85.2% in hypotonic saline and decreased to 80.1% in the most hypertonic saline. 5. Measurements of extracellular volume fraction and water content were combined to show that hypotonic solutions caused water to move from the extracellular to the intracellular compartment while hypertonic solutions caused water to move from the intracellular to extracellular compartment, with only a relatively small changes in total water in both cases. 6. These results suggest the use of the isolated turtle cerebellum as a model system for studying light scattering or diffusion‐weighted magnetic resonance imaging.
Roles of Technical and Functional Service Quality , and Cognitive and Affective Trust in IT Service Encounter

The purpose of this study is to examine the impact of IT service quality on trust, commitment and intention to continuously use the IT service. Service quality in this research is measured in two dimensions (technical and functional) while trust measured in two dimensions (cognitive and affective). An empirical model is proposed here, consisting of technical quality, functional quality, cognitive trust, affective trust, commitment and intention to use. The model was tested using 215 data points collected in a global electronics firm. Study results show that the cognitive and affective dimensions of trust are affected by functional and technical service quality. Interestingly, functional service quality seems to have effects stronger than technical service quality contrary to the expectation that technical quality of outcome would be more important than functional in case of IT services. Also, affective trust seems to maintain stronger effects than cognitive trust in raising the commitment level of IT service client. Further implications and limitations are discussed.
Synchronous mucinous cystadenoma ovary, leiomyoma uterus and mucinous adenocarcinoma cervix infiltrating into uterine leiomyoma: a rare case report

The synchronous or metachronous occurrance of multiple primary cancers in the genital tract is well recognized. The overall incidence of synchronous female genital tract malignancies is 0.63%. The most frequently observed synchronous neoplasms are those of the ovary together with the endometrium. These constitute 40% of all, and carry a favourable prognosis because of low malignant potential. Cervical and ovarian malignancies are still rare, and if they occur they have similar histopathology due to direct spread of cervical malignancy to ovary.
Social Class Migration and Chronic Bronchitis *

Morbidity studies by Logan (1960) have also shown a similar, though less steep, social class gradient. These class differences are generally thought to be due to adverse factors associated with life in the lower social classes (Registrar General, 1938, 1958b; Vernon, 1939; Goodman, Lane, and Rampling 1953; Pemberton, 1953; Lane, 1954; Fletcher, 1956; Stuart-Harris and Hanley, 1957). It is also possible that a drift down the social class scale of those disabled by bronchitis might contribute to the gradient in men, particularly the excess in Social Class V.

Temporal bone anomaly proposed as a major criteria for diagnosis of CHARGE syndrome.

The acronym CHARGE defines a non-random clustering of congenital malformations of unknown origin. Classical diagnostic criteria include: 1) one major feature namely coloboma/microphthalmia or choanal atresia, and 2) four of the six features designated in the CHARGE acronym. Interestingly, all CHARGE patients hitherto reported had partial or complete semicircular canal hypoplasia on temporal bone CT-scan. We report on semicircular canal agenesis/hypoplasia in three patients with three to four features of the CHARGE syndrome and neither coloboma nor choanal atresia and we propose to include temporal bone malformations as a major criteria for diagnosis of CHARGE syndrome.
