A Study of Anastomotic Aneurysms Following Aortofemoral Prosthetic Bypass

Between 1960–1979, 19 patients with aortofemoral prosthetic bypass for aneurysmal and/or occlusive disease subsequently developed 36 false aneurysms at the suture line, for an incidence of 4.5% (19/426 patients). The two major aneurysm sites were the femoral anastomosis 4.5% (33/727 patients), and the aortic anastomosis 0.7% (3/430 patients). Additionally, one patient with bilateral false aneurysms of the groin subsequently developed an aortoduodenal fistula. The initial operation was for aortoiliac occlusive disease in 14 and for abdominal aortic aneurysms plus severe occlusive disease in five. The false aneurysm(s) appeared three months to 17 years after the aortofemoral procedure. Eleven of 19 patients (57.9%) had multiple aneurysms (two to five) and developed both right and left groin aneurysms concomitantly or at different times. Suture failure was the major finding at operation. However, a common alternative finding was partial or near complete separation of the prosthesis from the host vessel and an intact suture line, thus indicating a structural weakness in the host vessel and/or severe mechanical stress, as the causative factor. One experience leads us to favor an aggressive surgical approach to these lesions. All false aneurysms were corrected as they were detected with good surgical results.
A recB recC sbcB recJ host prevents recA-independent deletions in recombinant cosmid DNA propagated in Escherichia coli

Segments of DNA are deleted from recombinant cosmid DNAs with high frequency during propagation in standard recA Escherichia coli hosts. An attempt has been made to derive an appropriate strain of E. coli, suitable for cosmid cloning, in which such deletions do not occur. We examined the effects of a series of host recombinational mutations on the deletion process, using six independent recombinant cosmids that carry inserts of mouse, Chinese hamster, or human DNA. Various E. coli host cells carrying the recombinant cosmids were cultured serially in liquid medium, and the recombinant cosmid DNAs were extracted from the host cells and analyzed by agarose gel electrophoresis and by gene transfer of the DNAs into cultured mammalian cells. Of the mutations examined, only a recB recC sbcB recJ (or recN) quadruple combination of host mutations prevented the deletion of DNA segments. The recombinant cosmid DNAs propagated in E. coli hosts that carried this combination of mutations were functionally as well as structurally intact. We propose that the recJ (and/or recN) gene is involved in some aspect of the events that lead to deletions of cosmid DNA in a recB recC sbcB genetic background.
Site distribution of cutaneous melanoma in queensland

The age‐adjusted incidence rates of cutaneous melanoma in Queensland in 1987 have been analysed for 16 anatomic sites, taking into account their surface areas. In men, the incidence of invasive melanoma on the ears, a chronically sun‐exposed site, was extraordinarily high with annual rates of over 200 per 105 units of surface area in the Queensland population. Next highest rates of over 100 melanomas per 105 units were found on the face, neck, shoulders and back in men and the face and shoulders in women. Comparison with site‐specific incidence rates in the same population 7½ years previously showed that incidence of invasive disease had significantly increased for all these sites, though the largest relative increase in this period occurred on the forearm in both men and women. Melanoma was very rare on the buttocks of both sexes and on the scalp in women, sites which receive the least sun exposure. These findings are consistent with the theory that excessive total sun exposure plays a major role in the aetiology of cutaneous melanoma.
Impairment of Alternative Macrophage Activation Delays Cutaneous Leishmaniasis in Nonhealing BALB/c Mice1

Expressed on various cell types, the IL-4Rα is a component of both receptors for IL-4 and IL-13. Susceptibility of BALB/c mice to Leishmania major is believed to be dependent on the development of IL-4- and IL-13-producing Th2 cells, while IFN-γ secretion by Th1 cells is related to resistance. Despite a sustained development of Th2 cells, IL-4Rα-deficient BALB/c mice are able to control acute cutaneous leishmaniasis, suggesting that IL-4Rα-bearing cells other than Th2 cells contribute to susceptibility. To analyze the contribution of the IL-4Rα on macrophages, recently generated macrophage/neutrophil-specific IL-4Rα-deficient mice on a susceptible BALB/c genetic background were infected with L. major. Strikingly, macrophage/neutrophil-specific IL-4Rα-deficient mice showed a significantly delayed disease progression with normal Th2 and type 2 Ab responses but improved macrophage leishmanicidal effector functions and reduced arginase activity. Together, these results suggest that alternative macrophage activation contributes to susceptibility in cutaneous leishmaniasis.
Electrodermal Activity in the 1980s: A Review 1

Aims and intentions This paper aims to provide pathways through the forest of nomenclature and techniques in contemporary electrodermatology, to describe the recording of some electrodermal indices in areas relevant to psychopharmacology, and to look briefly at developments likely to influence electrodermal work in the 1980s. The area is being reviewed, not by a psychopharmacologist, but by a psychophysiologist with interests in peripheral mechanisms underlying electrodermal phenomena. Measurement of electrodermal indices provides evidence of eccrine sweat gland activity and its variation with changes in psychological state: the eccrine sweat glands are innervated by sympathetic fibres (although there is cholinergic transmission at postganglionic sites) and, in normal ambient temperatures, palmar (or plantar) glands reflect responses to psychological rather than thermoregulatory stimuli. This review is necessarily superficial but useful expansion of some of its material can be found in a section of the 'Handbook of Biological Psychiatry' (van Praag et al. 1980), particularly chapters by Walrath & Stern, Siddle et a; Venables, Christie et al., Lader.
High resolution aerosol data from MODIS satellite for urban air quality studies

The Moderate Resolution Imaging Spectroradiometer (MODIS) provides daily global coverage, but the 10 km resolution of its aerosol optical depth (AOD) product is not suitable for studying spatial variability of aerosols in urban areas. Recently, a new Multi-Angle Implementation of Atmospheric Correction (MAIAC) algorithm was developed for MODIS which provides AOD at 1 km resolution. Using MAIAC data, the relationship between MAIAC AOD and PM2.5 as measured by the 27 EPA ground monitoring stations was investigated. These results were also compared to conventional MODIS 10 km AOD retrievals (MOD04) for the same days and locations. The coefficients of determination for MOD04 and for MAIAC are R2 =0.45 and 0.50 respectively, suggested that AOD is a reasonably good proxy for PM2.5 ground concentrations. Finally, we studied the relationship between PM2.5 and AOD at the intra-urban scale (⩽10 km) in Boston. The fine resolution results indicated spatial variability in particle concentration at a sub-10 kilometer scale. A local analysis for the Boston area showed that the AOD-PM2.5 relationship does not depend on relative humidity and air temperatures below ∼7 °C. The correlation improves for temperatures above 7–16 °C. We found no dependence on the boundary layer height except when the former was in the range 250–500 m. Finally, we apply a mixed effects model approach to MAIAC aerosol optical depth (AOD) retrievals from MODIS to predict PM2.5 concentrations within the greater Boston area. With this approach we can control for the inherent day-to-day variability in the AOD-PM2.5 relationship, which depends on time-varying parameters such as particle optical properties, vertical and diurnal concentration profiles and ground surface reflectance. Our results show that the model-predicted PM2.5 mass concentrations are highly correlated with the actual observations (out-of-sample R2 of 0.86). Therefore, adjustment for the daily variability in the AOD-PM2.5 relationship provides a means for obtaining spatially-resolved PM2.5 concentrations.
Access pattern based multi-layer bus virtualization controller

To prove Moore's law, the future multi-core architecture will have a vast number of heterogeneous processors, memories, and analog components. Network on a chip architecture is not appropriate for such systems due to high latency issues. With the increase of processor cores, the systems face address translation delay, data management delay and timing issues. In this article, we intended to develop a high-performance and low-power network on chip architecture called Pattern based Network Virtualization Controller (PNVC). The PNVC uses pattern descriptor that handles on-chip data communication and manages multiple bus systems. The pattern descriptors permit the programmer to define the structure of data access patterns and the number of buses which reduces the data access latency. An intelligent algorithm that manages the different data transfer patterns. To validate the suggested controller performance, we execute it on a Xilinx Virtex-7 FPGA VC707 board. To verify that the controller is capable of a variety of scenarios, we perform the different experiment. The results show that PNVC consumes 1.9x fewer hardware resources, improves bus bandwidth up to 1.68 times and achieves a maximum speedup of 3.64 for various application kernels.
Renormalization-group theory for the eddy viscosity in subgrid modeling.

Renormalization-group theory is applied to incompressible three-dimensional Navier-Stokes turbulence so as to eliminate unresolvable small scales. The renormalized Navier-Stokes equation now includes a triple nonlinearity with the eddy viscosity exhibiting a mild cusp behavior, in qualitative agreement with the test-field model results of Kraichnan. For the cusp behavior to arise, not only is the triple nonlinearity necessary but the effects of pressure must be incorporated in the triple term. The renormalized eddy viscosity will not exhibit a cusp behavior if it is assumed that a spectral gap exists between the large and small scales.
End-of-Life Decision Making and Communication of Bereaved Family Members of African Americans with Serious Illness.

OBJECTIVE The study objective was to examine factors that influence African American (AA) family members' end-of-life care decision outcomes for a relative who recently died from serious illness. METHODS A cross-sectional descriptive study design was used. Binary logistic and linear regressions were used to identify factors associated with decision regret and decisional conflict. Forty-nine bereaved AA family members of AA decedents with serious illness who died two to six months prior to enrollment were recruited from the palliative care program in a safety net hospital and a metropolitan church in the Midwest. Measurements used were the Decisional Conflict, Decision Regret, Beliefs and Values, and Quality of Communication scales. RESULTS Family members who reported higher quality of communication with health care providers had lower decisional conflict. Family members of decedents who received comfort-focused care (CFC) had significantly less decision regret than family members of those who received life-prolonging treatment (LPT). Family members who reported stronger beliefs and values had higher quality of communication with providers and lower decisional conflict. CONCLUSIONS This research adds to a small body of literature on correlates of end-of-life decision outcomes among AAs. Although AAs' preference for aggressive end-of-life care is well-documented, we found that receipt of CFC was associated with less decision regret. To reduce decisional conflict and decision regret at the end of life, future studies should identify strategies to improve family member-provider communication, while considering relevant family member and decedent characteristics.
Performance Bounds for Manoeuvring Target Tracking Using Asynchronous Multi-Platform Angle-Only Measurements

This paper presents the Cramer-Rao lower bounds (CRLBs) for the problem of single target tracking using angular measurements collected by distributed networked moving sensors. The specific cases considered in the paper include deterministic and stochastic constant velocity (CV) target motion, manoeuvring target with nonswitching (constant acceleration) and switching dynamic model. For completeness, the bounds are compared with the the performance of selected algorithms for the cases considered.
Automatic verification of fault tolerance using model checking

Model checking is a technique that can make a verification for finite state systems absolutely automatic. We propose a method for automatic verification of fault-tolerant systems using this technique. Unlike other related work, which is tailored to specific systems, we are aimed at providing a general approach to verification of fault tolerance. The main obstacle in model checking is state explosion. To avoid the problem, we design this method so that it can use SMV, a symbolic model checking tool. Symbolic model checking can overcome the problem by expressing the state space and the transition relation by Boolean functions. Assuming that a system to be verified is specified by guarded commands, we define a modeling language suited for describing guarded command programs and propose a translation method from the modeling language to the input language of SMV. We show the results of applying the proposed method to various examples to demonstrate the usefulness.
Analysis of the development of T cells by transferring precursors into cultured fetal thymus with a microinjector.

Development of T cells from precursors in the bone marrow or fetal thymus cells was investigated by transferring these cells into deoxyguanosine (dGuo)-treated organ cultured fetal thymus (FTOC) with a microinjector (micro i.t. method). Donor type T cells could be generated after transfer by the micro i.t. method of precursors present both in bone marrow and fetal thymus. The kinetics of the generation of T cells from these precursors was similar to that found in in vivo intra thymus transfer systems. As low as 300 fetal thymus cells were shown to be sufficient to repopulate a dGuo-FTOC. On the other hand, in a hanging drop culture method only precursors from the fetal thymus but not from the bone marrow were effective in repopulating the lobes. The hanging drop method was ineffective in repopulating all lobes, even when higher numbers of fetal thymus cells were applied. Moreover the number of T cells recovered per repopulated lobes was 2 to 3 times lower in the hanging drop system than in the micro i.t. system. It was also observed that the development of T cells was significantly accelerated by adding adherent cells from either the thymus or the spleen.
Coping and return to work: Measurement and theoretical issues

Sick leave and early departure from the workforce have serious adverse effects on both individuals and society. Motivation and coping are both important when attempting to return to work. In this article, we wanted to test if either of two coping instruments could predict return to work. Response outcome expectancies as defined in the Cognitive Activation Theory of Stress (CATS) (Ursin & Eriksen, 2004) were measured by the CODE scale (Eriksen et al., 1997) and general self-efficacy was measured by the generalized self-efficacy scale (GSE) (Schwarzer & Jerusalem, 1995). The instruments were tested in one group of rehabilitation patients (N= 135) and one group of disability pensioners (N=85), who participated in return to work interventions in randomised controlled trials. None of the instruments could predict return to work at any point of measurement. Less than 10% of the theoretical range of the scales was used. The scales appear to measure a concept that is more stable than their underlying theory predicts, and they can not predict an important outcome. Results indicate that caution is advised when making inferences from these instruments to their underlying theories.
Is picky eating an eating disorder?

OBJECTIVE To examine the prevalence of picky eating and the relationship between picky eating, previously supported correlates of picky eating, other child eating and behavioral problems and maternal eating problems in children aged 8-12 years. METHOD In a cohort study, 426 8- to 12-year-old children and their primary caretakers (91% mothers) were assessed in a small town community. Potential child eating behaviors associated with picky eating were reported by mothers using the Stanford Feeding Questionnaire. Child eating attitudes and disturbances were obtained from the McKnight Risk Factor Survey, food preferences and avoidances from a food preference list, child behavioral problems were assessed by the Child Behavior Checklist. To assess maternal eating disturbances EDI-subscales 1-3 as well as TFEQ-subscales "disinhibition" and "restraint" were used. RESULTS Picky and nonpicky eaters differed significantly on all of the child eating behaviors found to be correlates of picky eating in a previous study with younger children. Overall, picky children were reported to avoid foods in general more often than nonpicky eaters. Picky children did not differ from nonpicky children with regard to their own and maternal eating disturbances. However, picky children displayed more problem behaviors comprising both internalizing and externalizing behaviors. CONCLUSION The present study does not support the concept that picky eating is associated with disordered eating but rather with a range of behavioral problems.
Data transmission in dental identification of mass disaster victims.

UNLABELLED Dental evidence, especially from radiographs, has been found to be an effective method in personal identification. Previously, it has been shown that wireless personal digital assistants (PDA) can be used to transfer digitized radiographs. The purpose of this study was to set up a secure and reliable mobile connection for transferring dental digital images for disaster victim identification, and to test this new way of working in Phuket, Thailand, following the December 2004 Asian Tsunami disaster. MATERIAL AND METHODS Digital dental radiographs and clinical images were transferred in two separate sets using secured data transmission from a server in Finland to PDA terminals in Thailand. The mean size of the images in test 1 and test 2 were 90.7 kB and 88.1 kB, respectively. RESULTS The mean speed of the transmission was 3.7 kB/s with the Nokia 9500 and 3.4 kB/ s with the Qtek 2020i. The quality of all the pictures was found to be good enough for dental identification purposes. CONCLUSIONS Wireless personal digital assistants (PDA) together with data secure transmission of digital clinical information could be used in order to assist in disaster victim identification in areas where GSM cellular networks are available.
AN EXPANSION PROPERTY OF BOOLEAN LINEAR MAPS

Given a finite set $K$, a Boolean linear map on $K$ is a map $f$ from the set $2^K$ of all subsets of $K$ into itself with $f(\emptyset )=\emptyset$ such that $f(A\cup B)=f(A)\cup f(B)$ holds for all $A,B\in 2^K$. For fixed subsets $X, Y$ of $K$, to predict if $Y$ is reachable from $X$ in the dynamical system driven by $f$, one can assume the existence of nonnegative integers $h$ with $f^h(X)=Y$, find an upper bound $\alpha$ for the minimum of all such assumed integers $h$, and test if $Y$ really appears in $f^0(X), \ldots, f^\alpha(X)$. In order to get such an upper bound estimate, this paper establishes an expansion property for the Boolean linear map $f$. Namely, the authors find a lower bound on the size of $f^h(X)$ for any nonnegative integer $h$. Besides presenting several direct applications of the derived expansion property, this paper collects some related problems on Boolean linear dynamical systems, including problems on primitive multilinear maps and inhomogeneous topological Markov chains.
How iconic gestures and speech interact in the representation of meaning: Are both aspects really integral to the process?

Les mouvements involontaires des mains qui accompagnent le langage ont ete etudies et classes dans differentes categories par rapport a leur fonction. L'A. s'interesse ici au role communicationnel d'un type particulier de geste, le geste iconique qui a une signification reliee au contenu semantique de la parole. La theorie de McNeill concernant ce type de geste iconique lui confere une place importante dans le processus de signification, affirmant que sans le geste la communication perd de l'information. L'A. critique certains points de la theorie de McNeill et en propose une evaluation experimentale.
Plasma Testosterone and Cortisol Responses to Training-Intensity Exercise in Mild and Hot Environments

Seven endurance-trained and heat-nonacclimated men (Mean+/-SEM: 20+/-1 yr; VO2max = 67+/-2 ml x kg(-1) x min(-1)) ran in two environments (M: 23 degrees C, H: 38 degrees C; 7 days apart) at two absolute training-intensity velocities (S1: 240 m x min(-1); followed by S2: 270 m x min(-1); 10 min each) during the winter months. Blood samples were taken via cannula before (pre) S1 and after S1 and S2. Plasma testosterone (TEST) concentrations increased (p<0.05) above pre levels after S1 in M (19+/-3 versus 24+/-3 nmol x L(-1)) and H (18+/-2 versus 23+/-3 nmol x L(-1)), and after S2 in H (18+/-2 versus 24+/-1 nmol x L(-1)). Plasma cortisol (CORT) and the molar ratio of TEST/CORT were unchanged from pre levels after S1 and S2 during M and H. No differences were found in plasma TEST, CORT, or the molar ratio of TEST/CORT between M and H. These results indicated that circulating levels of TEST and CORT were not changed in endurance-trained, heat-nonacclimated athletes in response to short-duration running performed at the same absolute intensity in the heat, compared to mild environmental conditions. The lack of significant differences in the molar ratio of TEST/CORT, between the 23 degrees C and 38 degrees C trials, suggested that this short-duration exercise challenge performed in the heat was no more of an anabolic or catabolic stimulus for these athletes.
An over 200-W output power GaN HEMT push-pull amplifier with high reliability

We describe a state-of-the-art 250-W output power AlGaN/GaN HEMT push-pull transmitter amplifier operated at a drain bias voltage of 50 V. We also demonstrated stable operation under RF stress testing for 1000 h at a drain bias voltage of 60 V, for the first time. The amplifier, combined with a digital pre-distortion (DPD) system, also achieved an adjacent channel leakage power ratio (ACLR) of less than -50 dBc for 1-carrier W-CDMA signals with a drain supply voltage of 50 V. We show, for the first time, that an AlGaN/GaN HEMTs push-pull amplifier can fulfill the requirements of W-CDMA systems.
Divide-by-8 phase detector MMIC for PLL-based carrier recovery in E-band communication

A combined frequency divider and phase detector MMIC has been successfully realized in an GaAs mHEMT process with 100nm gate length, forming the base of a PLL carrier recovery for an E-band communication system. The frequency-divider-by-8 provides a sensitivity down to -54dBm - to the author's knowledge the highest sensitivity published in the E-band - and a bandwidth of 4.2GHz at a reference input power of -8 dBm. In an on-wafer measurement, the phase detector is measured with a detector gain of 293 mV/rad. In total, the IC draws a DC power of 734mW and measures 1.5 × 3.5 mm2.
