Cardiovascular System in Acute Experimental Peritonitis

The purpose of this work is to determine the reaction of the cardiovascular system to experimental peritonitis. Holzbach1 in his review on circulatory failure in infectious conditions states that functional heart failure appears early in peritonitis, but this opinion is apparently based on clinical observations since no experimental work of this condition is reviewed.Two types of peritonitis were induced in dogs. Fecal peritonitis was produced in 5 dogs by the intraperitoneal introduction of 5 gm. of small and large bowel feces suspended in 25 cc. of saline. Colon bacillus peritonitis was induced in another set of 5 dogs by the intraperitoneal injection of 50 cc. of a 2% gum tragacanth in saline containing 200 million B. coli per cc. In each of the animals blood pressure was obtained prior to and continuously after the onset of peritonitis by insertion into the carotid artery of a cannula which was connected to a mercury manometer and recorded on a kymograph. The animals were under pento-barbital sodium a...

Combined Volume Registration and Visualization

We describe a method for combining and visualizing a set of overlapping volumetric data sets with high resolution but limited spatial extent. Our system combines the calculation of a registration metric with ray casting for direct volume rendering on the graphics processing unit (GPU). We use the simulated annealing algorithm to find a registration close to optimal and allow the user to closely monitor the optimization progress. The combined calculation reduces memory traffic, increases rendering frame rate, and makes possible interactive-speed, user-supervised, semi-automatic combination of many component volumetric data sets.

A Discussion of Methods for Predicting Patients Who are Prone to Platelet Thromboembolism Including Measurements of Blood Components

The belief that aggregates of platelets may develop in the circulation and interfere with the vascular supply to vital organs is certainly not a new concept. It received further support from the observations of morphologists who found platelet aggregates as prominent components of thrombi and from studies in which the infusion of aggregating agents into local vascular beds caused organ injury or infarction in association with the formation of platelet aggregates. These lesions failed to develop if the animals were treated with inhibitors of platelet aggregation prior to the infusion of the aggregating agent.

Transport of biomolecules to binding partners displayed on the surface of microbeads arrayed in traps in a microfluidic cell

Arrays of probe molecules integrated into a microfluidic cell are utilized as analytical tools to screen the binding interactions of the displayed probes against a target molecule. These assay platforms are useful in enzyme or antibody discovery, clinical diagnostics, and biosensing, as their ultraminiaturized design allows for high sensitivity and reduced consumption of reagents and target. We study here a platform in which the probes are first grafted to microbeads which are then arrayed in the microfluidic cell by capture in a trapping course. We examine a course which consists of V-shaped, half-open enclosures, and study theoretically and experimentally target mass transfer to the surface probes. Target binding is a two step process of diffusion across streamlines which convect the target over the microbead surface, and kinetic conjugation to the surface probes. Finite element simulations are obtained to calculate the target surface concentration as a function of time. For slow convection, large diffu...
INCIDENCE OF VALVE LEAFLET THROMBOSIS IN TRANSCATHETER AND SURGICAL BIOPROSTHETIC AORTIC VALVES BY 4D CT IMAGING

Background: The incidence of valve thrombosis after transcatheter aortic valve replacement (TAVR) and surgical AVR (SAVR) when referred for clinical and echocardiographic indications, as well as response to anticoagulation is unknown. Methods: Between 11/2015 and 10/2016, all patients with clinical
Dopamine Transporter Imaging has no Impact on Functional Outcomes in de Novo Probable Parkinson's Disease.

Background Parkinson's disease (PD) is among the most prevalent neurodegenerative conditions. While motor and non-motor aspects of this disease have been well characterized, no objective biomarker exists to support an accurate clinical diagnosis. However, newer imaging techniques, including [123I]-FP-CIT (DaTSCAN), have demonstrated utility in differentiating between PD and non-neurodegenerative tremor disorders. Objective DaTSCAN has been primarily investigated in situations where diagnostic confusion exists, and in these instances has been shown to significantly impact clinical management. The goal of this pilot study was to evaluate the impact of DaTSCAN on the clinical management of patients with early probable PD, where no diagnostic uncertainty exists. Methods This was a prospective, 54-week, comparative pilot study, in which twenty subjects with de novo PD were randomly assigned to DaTSCAN either immediately upon diagnosis (and again at 6 and 12 months) or delayed to 6 months (and again at 12 months). The primary outcome measure was the frequency of deviation from the initial treatment plan from baseline to 54 weeks between the two groups. Secondary outcomes included motor and non-motor assessments. Results There was no significant difference in the number of treatment changes over the course of the study between the two groups: initial imaging group = 4.2 (SD:2.74) vs. delayed imaging group = 2.3 (SD:2.0, p = 0.11). In addition, there were no group differences in medication requirements, motor performance, or patient expectations of disease. Conclusions In patients with early, probable PD, DaTSCAN contributes no additional impact on clinical management or functional outcomes when added to the diagnostic algorithm.
Factors Contributing to Cognitive Absorption and Grounded Learning Effectiveness in a Competitive Business Marketing Simulation.

This study aimed to establish a pedagogical positioning of a business marketing simulation as a grounded learning teaching tool and empirically assess the dimensions of cognitive absorption related to grounded learning effectiveness in an iterative business simulation environment. The method/design and sample consisted of a field study survey instrument following the completion of an iterative marketing simulation with six decision periods. The matched, cross-sectional sample consisted of 391 undergraduate business students enrolled in marketing principles classes. The study used structural equation modeling to investigate the relations between the dimensions of cognitive absorption and grounded learning effectiveness. The model predicted 57% of the variance in grounded learning effectiveness. Ten hypotheses were tested in this study; and the results indicated that heightened curiosity, simulation behavioral control, and heightened enjoyment were significant predictors of grounded learning effectiveness. ...
Cutaneous Adverse Events of Targeted Therapies for Hematolymphoid Malignancies

The identification of oncogenic drivers of liquid tumors has led to the rapid development of targeted agents with distinct cutaneous adverse event (AE) profiles. The diagnosis and management of these skin toxicities has motivated a novel partnership between dermatologists and oncologists in developing supportive oncodermatology clinics. In this article we review the current state of knowledge of clinical presentation, mechanisms, and management of the most common and significant cutaneous AEs observed during treatment with targeted therapies for hematologic and lymphoid malignancies. We systematically review according to drug-targeting pathway the cutaneous AE profiles of these drugs, and offer insight when possible into whether pharmacologic target versus immunologic modulation primarily underlie presentation. We include discussion of tyrosine kinase inhibitors (imatinib, dasatinib, nilotinib, bosutinib, ponatinib), blinatumomab, ibrutinib, idelalisib, anti-B cell antibodies (rituximab, ibritumomab, obinutuzumab, ofatumumab, tositumomab), immune checkpoint inhibitors (nivolumab, pembrolizumab), alemtuzumab, brentuximab, and proteasome inhibitors (bortezomib, carfilzomib, ixazomib). We highlight skin reactions seen with antiliquid but not solid tumor agents, draw attention to serious cutaneous AEs that might require therapy modification or cessation, and offer management strategies to permit treatment tolerability. We emphasize the importance of early diagnosis and treatment to minimize disruptions to care, optimize prognosis and quality of life, and promptly address life-threatening skin or infectious events. This evolving partnership between oncologists and dermatologists in the iterative characterization and management of skin toxicities will contribute to a better understanding of these drugs' cutaneous targets and improved patient care.
Microfluidics for exosome isolation and analysis: enabling liquid biopsy for personalized medicine

Exosomes, the smallest sized extracellular vesicles (∽30–150 nm) packaged with lipids, proteins, functional messenger RNAs and microRNAs, and double-stranded DNA from their cells of origin, have emerged as key players in intercellular communication. Their presence in bodily fluids, where they protect their cargo from degradation, makes them attractive candidates for clinical application as innovative diagnostic and therapeutic tools. But routine isolation and analysis of high purity exosomes in clinical settings is challenging, with conventional methods facing a number of drawbacks including low yield and/or purity, long processing times, high cost, and difficulties in standardization. Here we review a promising solution, microfluidic-based technologies that have incorporated a host of separation and sensing capabilities for exosome isolation, detection, and analysis, with emphasis on point-of-care and clinical applications. These new capabilities promise to advance fundamental research while paving the way toward routine exosome-based liquid biopsy for personalized medicine.

Fabrication and properties of novel polymer-metal composites using fused deposition modeling

Abstract This study investigated the novel fabrication of polymer-metal composites using fused deposition modeling (FDM), and evaluated the mechanical and physical properties of the new materials. Specifically, an acrylonitrile butadiene styrene (ABS) – 420 stainless steel (SS) composite system was used, with 10, 15, and 23 wt% SS powder additions, and the resulting properties were compared to those of base ABS prepared using the same printing conditions. A new methodology to fabricate the composites was developed. The resulting materials were extruded into composite filaments, which were used to print test specimens. Tensile testing, modulated differential scanning calorimetry, and scanning electron microscopy were employed to characterize the composite materials and evaluate the effects of different print conditions. The results demonstrate, for the first time, the feasibility of using FDM to prepare ABS-SS composites that maintain or enhance mechanical properties as compared to the base polymer, while adding increased functionality.
Stator Current Model Validation for Rotor Faults Diagnosis

Early rotor faults diagnosis is essential for induction motor life. The reason for which several signal processing diagnosis methods have been proposed. In order to enhance these methods, it is necessary to use a reliable mathematical model of the physical processed signal. Unfortunately, the stator current is usually obtained from an expensive measurement set-up or a complex modelling of the electric motor. The aim of this paper is therefore to use a model of the motor stator current under rotor fault condition. In other words, the searched model must take into account the effects of the fault. Indeed, it has been verified that the effect of a fault is reflected by an amplitude modulation as well as a phase modulation of the stator current corresponding respectively, to a load torque oscillation and an eccentricity in the air-gap. The paper will also investigate the impact of the severity of the rotor fault on these two types of modulation. Finally, a comparison study between both the simulated signal and the experimental signal is carried out to illustrate the merits of the model and its effectiveness.
AN ADM SPEECH CODING WITH TIME DOMAIN HARMONIC SCALING

A semi-waveform speech coder is presented that combines adaptive delta modulation (ADM) with time domain harmonic scaling (TDHS) to achieve good quality speech coding at 4.4 kb/s. The use of TDHS reduces the transmission bit rate by 50%, while still maintaining good speech quality. Compared to other coding schemes of the same data-rate range, the proposed method is simple and fast. Another feature of this method is the variable output data-rate which is suitable for combined source and channel coding.

Pathogenesis of Steroid-Induced Avascular Necrosis and Its Response to Lipid Clearing Agent

Steroid-induced avascular necrosis of bone is a fascinating and complex disease entity. While the mechanism of the disease is controversial, previous studies in the rabbit have shown that high doses of steroids caused significant alterations in lipid metabolism. The study described here was designed to show the effects of steroid therapy on serum lipids, liver morphology, marrow volume changes, and eventually on femoral head pressure and its blood flow changes. With prolonged steroid treatment it was noted that the fat droplets that were observed in small vessels of the treated rabbits led to eventual focal occlusion of the subchondral arterioles. There was also a persistent elevation of serum cholesterol and a gradual increase of fat cell size, from 60 µm in the normal untreated 0rabbit to 70 µm after 7 weeks of treatment. There was a concomitant increase of femoral head pressure, from 24.6 ± 5.5 cm of water in controls, to 60 cm of water in treated rabbits at 10 weeks of treatment. Simultaneously it was observed that the blood flow of the femoral head decreased from 0.23ml/min per g in the control to 0.16ml/min per g after 10 weeks of steroid treatment. An antilipid agent was used in an attempt to reverse the ongoing process. The result of simultaneous use of a steroid and a lipid clearing agent indicated that there was a slight improvement in cholesterol level, but that the intrafemoral head pressure was maintained. Measurement of blood flow also indicated that the femoral head blood flow was preserved. Concomitant study of fat vacuoles within the osteocytes revealed modification of fatty accumulation within these cells. We fell that lipid clearing agents are beneficial in preventing steroid-induced avascular necrosis.
Long-term performance of a pacing lead family: A single-center experience.

Background The performance of Abbott/St. Jude Medical (Sylmar CA) Tendril pacing leads has not been well characterized. Objective We sought to assess the performance of Tendril leads as compared with that of different pacing leads. Methods We retrospectively identified patients implanted with the following leads: Tendril leads 1888 TC, 2088 TC, and 1688 TC, Medtronic (Fridely, MN) 4076 CapSureFix Novus, and Boston Scientific (Natick, MA) FINELINE II Sterox Pacing EZ leads (models 4469, 4470, and 4471). The primary end point was the incidence of lead malfunction assessed by Kaplan-Meier analysis. Results During the study period, 9782 leads were implanted, including 8512 Tendril leads, 731 Medtronic 4076 CapSureFix Novus leads, and 539 FINELINE II leads. A total of 540 leads (5.5%) malfunctioned during a mean follow-up of 3.6 ± 2.9 years. Lead malfunction manifested predominantly as noise and/or low impedance (95%). Lead malfunction rates were significantly higher at 5 years for Tendril vs non-Tendril leads (7.0% vs 2.1%; P Conclusion Tendril leads appear to have a higher rate of malfunction than do comparator leads. Optim insulation may partly explain the higher failure rate.

Genetic parameter estimates and GxE interaction in a large cloned population of Pinus taeda L.

Cloned progeny tests in forest tree breeding provide the ability to assess the same genotypes across multiple environments and partition observed phenotypic variance into additive and non-additive genetic effects. In this study, 2362 clones from 53 crosses of loblolly pine (Pinus taeda L.) were tested across eight locations in the Southern US. Alpha cyclic incomplete row-column design was used to accommodate a large number of clones in a replication. Tree stem volume (cubic decimeter) was assessed at age 6 using various variance-covariance structures of mixed models. Models with factor analytic additive genetic structures and spatially correlated residuals or polynomial fixed row and column effects efficiently captured heterogeneity in the data. The narrow-sense clone mean heritability estimate for stem volume was 0.41 for the simple compound symmetry additive genetic structure. The estimates were higher for more complex models, ranging from 0.56 to 0.61. Non-additive genetic variance for stem volume was about a fraction of the additive genetic variance, suggesting that the trait is mainly controlled by large number of genes each with small effect. The results suggested that for forest trees genetic field tests with large number of genetic entries, breeders should consider incomplete row-column designs to model micro-site heterogeneity in two directions. These designs allow spatial modeling using row and column information, which can efficiently account for heterogeneity in the environment, resulting in higher heritability estimates and more reliable ranking of varieties for selection.

Lateral Epicondylitis: A Common Cause of Elbow Pain in Primary Care

Lateral epicondylitis (LE) is an overuse injury of the lateral elbow. LE is caused by repetitive motion leading to micro-injury of the wrist extensor muscles that originate along the elbow's lateral aspect. Although LE is commonly referred to as “tennis elbow” many cases are observed in non-athletes. Due to its prevalence in the general population, primary care physicians must be prepared to diagnose and treat LE. Physicians should look for a history of repetitive activities involving patient’s jobs or recreational activities. Exam findings are characterized by pain and tenderness just distal to the lateral epicondyle of the humerus. Resisted movement with an extension of the wrist will typically elicit pain. Ultrasonography is considered the imaging modality of choice for diagnosing LE. Standard radiographs and magnetic resonance imaging (MRI) may be helpful. However, diagnosis can usually be made by history and physical examination alone. Most cases of LE respond favorably to conservative therapy. There are several nonoperative options for treatment, but a combination of non-steroidal anti-inflammatory drugs (NSAIDs) and physical therapy that utilizes eccentric muscle stretching is considered first-line. Osteopathic manipulative medicine is also useful in the treatment of LE. Muscle energy (ME) and joint mobilization techniques have been shown to be particularly effective. If non-surgical therapy fails, surgical intervention may provide patients with an additional benefit. This article will review some of the treatment options described above and discuss other diagnostic and therapeutic considerations relevant to LE's management in the primary care setting.
Enhanced capillary performance of grooved nanocarbon foams as wicks for heat pipes

Abstract An effective heat pipe needs a great amount of working liquid to be moved quickly from the cold end to the hot end. That is why capillary performance works as a critical factor to evaluate the potential of a wick for high-efficient heat pipes. However, good capillary performance only means that the liquid can be transferred quickly; the amount of liquid transferred during capillary rising also needs to be taken into account. In this work, novel grooved nanocarbon foam (GNCF) wicks were fabricated with good capillary performance and a large capillary rise amount. Grooves with different numbers, depths, and widths were formed on the nanocarbon foams (NCFs) and the effect of these factors on the capillary performance was studied. The results indicate that the groove is beneficial to improve the capillary performance of NCFs due to the enhanced permeability and feeding effect. The capillary performance is achieved with a capillary rise height of 45 mm in 14 s. It is 2.5 times as high as that of the NCF and better than some other published results. Moreover, because the GNCFs have a superhigh porosity of 0.99, they are capable to transfer much more working liquid per time than other wicks with similar capillary performance.
Differential effects of IFNβ on IL-12, IL-23, and IL-10 expression in TLR-stimulated dendritic cells (BA7P.157)

Autoimmune disease multiple sclerosis (MS) is characterized by immune cell infiltration in the CNS leading to cumulative disability. IFNβ, used clinically in remitting-relapsing MS, reduces lesion formation and rate of relapses. Although the molecular mechanisms are not entirely elucidated, myeloid cells appear to be a major target for the therapeutic effects of IFNβ. Dendritic cells (DC) play a critical role in experimental models of MS, through their effect on Th1/Th17 cell differentiation and expansion. Here we studied the effects of IFNβ on DC expression of cytokines involved in Th1/Th17 differentiation. Administration of IFNβ to EAE mice inhibited IL-12 and IL-23 expression in splenic DC and reduced in vivo differentiation of Th1/Th17 cells. IFNβ affected cytokine expression in TLR-stimulated DC in a similar manner in vitro, inhibiting IL-12 and IL-23 and stimulating IL-10 at both mRNA and protein levels, by signaling through IFNAR. We investigated the role of the signaling molecules STAT1/STAT2, IRF1 and IRF7, and of the PI3KaGSK3 pathway. Inhibition of IL-12 p40 and p35 by IFNβ was mediated through STAT1/STAT2, whereas inhibition of IL-23 was STAT1-depedent, and the stimulatory effect on IL-10 expression was mediated through STAT2. Although IFNβ induces IRF-7 and IRF-1, neither IRF mediated the effects of IFNβ on IL-12, IL-23, or IL-10. We found that the PI3K pathway mediated IL-12 inhibition but did not interfere with the inhibition of IL-23 or stimulation of IL-10.

Episodios del «Persiles» configurados a base de 'ejemplos bizantinos' de las «Gesta Romanorum»

Only recently has there been a recognition of the literary influence in Spain of the ‘examples’ found in the Gesta Romanorum , a collection of tales widely spread and fertile in adaptations throughout Medieval and Renaissance northern Europe. Just as other Hispanic writers did who were contemporaries of Cervantes, he would have been able to read them without difficulty in the original Latin, which is highly simplified for the use of preachers. The plot and images of two of the gesta written in the style of a Byzantine novel shape corresponding episodes in the Persiles , which is well known for Cervantes’ statement that in it he sought to compete with the Byzantine novel set in Ethiopia by Heliodorus. A whale swallowing Auristela’s ship in one of the tales, like her rescue and subsequent forced choice between suitors, provide situations and phrases used by Cervantes to portray the intense love between Persiles and his sweetheart/pretended sister, Sigismunda, as was done also in other Hispanic adaptations of the legend.

A constrained total least squares approach for sensor position calibration and direction finding

In this paper we present a new maximum likelihood array signal processing algorithm that uses self-calibration and the total least squares (TLS) technique for improved direction finding when the sensor (or antenna) positions are not known exactly. The TLS method is a generalized data fitting method that is appropriate for cases when the system model contains error or is not known. In order to apply TLS techniques to array signal processing, we propose constrained-TLS (C-TLS) and show that the solution can be represented by combining the constraint and the least squares (LS) approach. The algorithm performs calibration and direction estimation iteratively using both TLS and C-TLS techniques. >
Testing: Concepts, Issues, and Techniques

The basic idea of testing involves the execution of software and the observation of its behavior or outcome. If a failure is observed, the execution record is analyzed to locate and fix the fault(s) that caused the failure. Otherwise, we gain some confidence that the software under testing is more likely to fulfill its designated functions. We cover basic concepts, issues, and techniques related to testing in this chapter.
Identification of a variant subgroup A strain of respiratory syncytial virus.

During epidemiologic surveillance of children with respiratory syncytial virus (RSV) disease in Huntington, W.Va., we identified seven strains of a new variant subgroup A RSV (subgroup A-Var) by their reactions in an enzyme immunoassay with two anti-F monoclonal antibodies (MAbs) specific for two epitopes, F1 and F4, generated against the subgroup B RSV. The prototype strain of subgroup A and all other subgroup A field strains from that epidemiologic year failed to react with these two subgroup B MAbs. Additional enzyme immunoassays with 18 subgroup B anti-F MAbs specific for 14 epitopes showed that subgroup A-Var strains also reacted with a MAb specific for the subgroup B F2 epitope. In a radioimmune precipitation assay, the molecular size of the subgroup A-Var F2 subunit of the fusion (F) protein clearly differed from those of both prototype strains of subgroup A and subgroup B RSV. The molecular size of the F2 subunit of subgroup A-Var (24 kDa) was intermediate between the size of the F2 subunit of subgroup A (25 kDa) and that of subgroup B (23 kDa). However, the molecular sizes of the F1 subunits of both subgroup A and subgroup A-Var were identical (54 kDa) and slightly larger than those of the F1 subunits of both subgroups B1 and B2 (53 kDa). These data suggest that subgroup A-Var may represent a distinct RSV A subgroup, analogous to subgroup B1 and B2 RSV, and it is the first-identified naturally occurring subgroup A RSV with an F protein different from that of the prototype A RSV.
Chapter 8 Deep Level Defects in Epitaxial III/V Materials

Publisher Summary This chapter describes deep level defects in epitaxial III/V materials. Epitaxial III/V materials play an increasingly important role in a variety of electronic, optoelectronic, and optical applications. The development of new epitaxial growth processes and improvements to already existing techniques have enabled the growth of layers of a quality (expressed by the quantity of structural and electronic defects) previously unobtainable for bulk III/V crystals. Therefore, the III/V material-based devices are now frequently fabricated using homoepitaxial layers grown on the corresponding bulk substrates. But the even greater importance of III/V epitaxial processes stems from the fact that they facilitate the growth of heteroepitaxial structures with properties unavailable for devices fabricated using bulk crystal materials. The electronic properties of the III/V epilayers are in many instances, as in the case of bulk crystals, modified by the deep states present in their band gaps. Some of them are beneficial and have been successfully employed either to improve existing devices or to obtain structures with new characteristics.
The evolution of nighttime mid-latitude mesoscale F-region structures: A case study utilizing numerical solution of the Perkins instability equations

Abstract In recent years, all-sky camera airglow observations of evolving nighttime F-region structures have raised questions regarding the formation and apparent motion of these often wave-like structures. We address these issues using a pseudo-spectral method code developed to numerically solve the Perkins (1973. Spread F and ionospheric currents. J. Geophys. Res. 78, 218–226) moment equations modeling F-region electrodynamics. To aid in interpretation of the results, we utilize a Gaussian shape initial condition of the (geomagnetic field, B, parallel) integrated conductivity under the homogeneous TEC (B-parallel total electron content) condition and a northeastward DC electric field (E-field). We find that the initial Gaussian shape conductivity structure gradually evolves into banded structures oriented along the northwest–southeast direction while the amplitude of the banded structures continues growing and the peak of the structure moves to the northwest due to the E×B drift. The potential distribution corresponding to the initial Gaussian conductivity distribution is more complex but also becomes banded with the same orientation and growing trend as the conductivity. Wave vector domain plots show structure growth in approximately the first and third quadrants and damping in the second and fourth quadrants for both the conductivity and potential, as Perkins predicts—this leads to the orientation of the structures. We note that the evolved banded structures in conductivity and potential are oriented perpendicular to the direction given by half the angle between the DC E-field and east—the direction of maximum instability growth rate predicted by Perkins. The polarization (perturbation) E-field is seen mainly perpendicular to the long axis of the banded structures—i.e., no obvious structure-parallel E-field is observed in the simulation. By tracking the maximum point of the conductivity as a function of time, it is found that the localized structures move northwestward at a nearly constant speed that corresponds to the E×B drift velocity (to within relative errors on the direction and magnitude of ≃4%). We also note that the E×B drift velocity has a dominant effect on the speed and propagation direction of the wave-like bands. The “wave” velocity is the projection of the E×B drift velocity on the line perpendicular to the wave front. Thus, the movement of a northwest–southeast oriented band can be decomposed into two components—parallel (to the band, northwestward) and perpendicular (southwestward) motions. A preliminary comparison of these results with an Arecibo all-sky camera observations shows good agreement.
Reduction of pain-related behaviors with either cold or heat treatment in an animal model of acute arthritis

Abstract Objective: To assess the effects of heat and cold on quantifiable pain behaviors in an animal model of arthritis that minimizes the motivational-affective component of pain. Design: The effects of superficial heat (40°C) and cold (4°C) on pain behaviors in rats with knee joint inflammation were tested before and after induction of inflammation and after treatment with heat or cold. Subjects: Joint inflammation was induced in male Sprague-Dawley rats by intra-articular injection of the knee joint with 3% kaolin and 3% carrageenan. Main Outcome Measures: Withdrawal latency to heat applied to the paw (PWL) assessed secondary hyperalgesia; spontaneous pain behaviors assessed degree of weight bearing/guarding; and joint circumference assessed joint swelling. Results: Cold treatment of the inflamed knee joint significantly reversed the PWL immediately after treatment ( p = .003) without affecting spontaneous pain behaviors or joint circumference. In contrast, heat treatment produced a small but significant decrease in spontaneous pain behaviors ( p = .03) without affecting PWL or joint circumference. Conclusion: Acute arthritic pain can be treated with either superficial heat for reducing guarding or with cold for reducing pain or hyperalgesia outside the injury site.
Addition of electrophiles to metalladiborane anions [M(CO)4(η2-B2H5)]− (Fe, Ru, Os)

Abstract Addition of the electrophiles [CH 3 ] + , H + , [(PPh 3 Au)] + to the metalladiborane anions [M(CO) 4 (η 2 -B 2 H 5 )] − (M = Fe, Ru, Os) has been investigated. Addition occurs at the metal center. The complexes CH 3 Os(CO) 4 (η 2 -B 2 H 5 ), HM(CO) 4 (η 2 -B 2 H 5 ) (M = Ru, Os), and (PPh 3 )AuM(CO) 4 (η 2 -B 2 H 5 ) (M = Fe, Ru, Os) have been formed. NMR spectra of HM(CO) 4 (η 2 -B 2 H 5 ) indicate that the H atom on the metal is cis to the B 2 H 5 ligand. Relative stabilities of the complexes LM(CO) 4 (η 2 -B 2 H 5 ) are in the order M = Os > Ru > Fe for a given electrophile and the order L = (Ph 3 P)Au > H for a given metal.
Excellent results of cardiac surgery in patients with previous liver transplantation.

Cardiovascular diseases requiring surgical therapy in patients with prior liver transplantation are rare. Little is known about the outcome of patients with liver allograft undergoing cardiac surgery. Herein we report our experience in this patient population with an emphasis on operative outcomes and mid-term survival. Between January 1998 and December 2004, 12 patients (mean ± standard deviation age 68 ± 9 years, 7 [58%] male) with previous liver transplantation who underwent cardiac surgery were identified. Main outcome measures were hospital mortality, postoperative complications, allograft function, and long-term survival. There was no in-hospital mortality. Three major complications (25%) occurred, including 1 each (8%) of respiratory failure, renal failure, and biliary leakage. All complications were resolved by the time of discharge. Allograft dysfunction determined by an increase of liver function parameters was noticed in 4 (33%) and recovered before discharge. The average length of stay in intensive care unit was 72 ± 45 hours, and the mean length of stay in hospital was 22 ± 17 days. One- and 5-year survival was 91% ± 8% and 67% ± 14%, respectively. Cardiac surgery can be performed safely in liver transplant recipients with extremely low mortality and acceptable morbidities. Allograft dysfunction is a common finding, but it is transient, with early functional recovery. Five-year survival of liver recipients undergoing cardiac procedures is similar to that of the general population undergoing cardiac surgery. Our data suggest that these patients should be considered for cardiac surgery in reference centers with expertise in complex cardiac procedures and perioperative management of these highly specific patients.

The Changing Self-Concept of Pregnant and Parenting Teens.

Self-concept has been recognized and researched as a powerful variable in relation to teenage pregnancy. Low self-concept frequently has been identified as a cause and consequence of teenage pregnancy as well as a factor in participation and compliance with health care recommendations. Most of the research on self-concept and teenage pregnancy occurred in the 1970s to mid-1980s, and all found lower self-concept in pregnant and parenting teens when compared with their nonpregnant contemporaries and normative data. This study found the opposite to be true. The 126 pregnant and parenting teens in this study had higher self-concepts than the reported normative group. Also, important variations in self-concept were found in relation to sociodemographics. This potentially suggests that what was once known about this aggregate is no longer true, and a reinvestigation is warranted. The purpose of this study was to reinvestigate the self-concept of pregnant and parenting teens and compare them with published normative data and to examine the relationship between sociodemographics and self-concept. The study employed a survey methodology. Data were analyzed using frequencies, percentages, measures of central tendency and dispersion, t test, chi-square test, and analysis of variance. This study found that pregnant and parenting teens had a higher self-concept than the normative data on nonpregnant teens reported by the research instrument authors. Furthermore, this older sample of pregnant and parenting teens (mean age, 17.83 years) had self-concepts more similar to the junior high school normative sample than their senior high school-age contemporaries. Also, this study found that self-concept varies according to the pregnant and parenting teens' ages, years of schooling, types of schools attended, income sources, and receipt of public assistance. This study has implications for health care providers, health and public educators, and nursing researchers in terms of program development and evaluation, health marketing, and development of primary prevention strategies.
Lymphangiomyoma and tuberous sclerosis

A patient with tuberous sclerosis and biopsy-proven lymphangiomyoma is presented. Lymphangiomyoma is a hamartomatous proliferation of predominantly smooth muscle that involves the lung and lymph nodes. It gives a syndrome of chylothorax, diffuse pulmonary reticular pattern, and frequent spontaneous pneumothorax. That the pulmonary involvement of tuberous sclerosis is practically identical, both grossly and microscopically, to that of lymphangiomyoma and that both syndromes occur in females between 20 to 50 years of age, suggests a common pathologic basis. The concept that lymphangiomyoma is a hamartoma makes this association an attractive one. The presence of chylothorax has been emphasized as a possible differential point between these two entities. However, 2 cases of tuberous sclerosis with chylothorax have now been reported. The presence or absence of chylothorax may depend on whether the thoracic duct is involved.
Kenneth Burke's concept of substance

An exploration of Burke's use of the term “substance” leads to an illumination of his critical theory and practice. Substance as consciousness achieved through verbalization is manifest in three behaviors: naming, forming, and structuring.
Tubal Ectopic Pregnancy: Contemporary Diagnosis, Treatment, and Reproductive Potential

ABSTRACT Sensitive diagnostic modalities, including urinary hCG testing and transvaginal ultrasonography, have allowed clinicians the opportunity to detect ectopic gestation at an earlier time. As a result, conservative treatment has become more practical. The evolution from the more radical surgical approaches to conservative measures, including medicinal therapy, is discussed.

Mechanical properties and morphology of nylon-6/acrylonitrile-butadiene-styrene blends compatibilized with imidized acrylic polymers

The mechanical properties and phase morphology of blends of nylon-6 with various acrylonitrile-butadiene-styrene (ABS) materials and compatibilizers are explored. The main focus was on nylon-6/ABS blends compatibilized with one particular imidized acrylic polymer that is miscible with the styrene-acrylonitrile (SAN) matrix of the ABS and has nearly optimal content of functional groups (anhydride and free acid) for reaction with nylon-6 to form graft copolymers in situ at the polymer-polymer interfaces. The effects of compatibilizer content, rubber concentration and the mixing protocol on the mechanical properties of these blends were extensively explored. In general, the most efficiently dispersed ABS domains in the nylon matrix led to the lowest ductile-brittle transition temperatures and the maximum tensile modulus for the super-tough nylon-6/ABS blends. The effects of varying the functionality and miscibility characteristics of imidized acrylic polymers on the mechanical properties and morphology of nylon-6/ABS blends were also investigated. Some other types of polymers with a high anhydride content were also tested as compatibilizers for this system. It appears that compatibilizers with high levels of reactive functinality are not very effective; hence, there is an optimal level of functionality.
The condensation and fractionation of refractory lithophile elements

It is noted that Cr, Mg, and Si are fractionated in chondritic material along with, but to a lesser extent than, a large group of more refractory elements. These patterns are reexamined with the reasoning that this might imply some unique distribution at the time of fractionation. It is shown that apparently two distinct fractionization patterns can be resolved: one involving ordinary and enstatite chondrites and the other involving carbonaceous chondrites, the earth, the moon, and the eucrite parent body. It is noted that the two trends intersect at C1 composition. Attention is given to the range in which the largest fraction of planetary matter condenses. It is concluded that the appearance of large amounts of condensed materials is conceivably in some way related to the fractionization process, although the exact relationship cannot be specified.
