Atrial septal aneurysm in adult patients. A multicenter study using transthoracic and transesophageal echocardiography.

BACKGROUND An atrial septal aneurysm (ASA) is a well-recognized abnormality of uncertain clinical relevance. We reevaluated the clinical significance of ASA in a large series of patients. The aims of the study were to define morphological characteristics of ASA by transesophageal echocardiography (TEE), to define the incidence of ASA-associated abnormalities, and to investigate whether certain morphological characteristics of ASA are different in patients with and without previous events compatible with cardiogenic embolism. METHODS AND RESULTS Patients with ASA were enrolled from 11 centers between May 1989 and October 1993. All patients had to undergo transthoracic and transesophageal echocardiography within 24 hours of each other; ASA was defined as a protrusion of the aneurysm > 10 mm beyond the plane of the atrial septum as measured by TEE. Patients with mitral stenosis or prosthesis or after cardiothoracic surgery involving the atrial septum were excluded. Based on these criteria, 195 patients 54.6 +/- 16.0 years old (mean +/- SD) were included in this study. Whereas TEE could visualize the region of the atrial septum and therefore diagnose ASA in all patients, ASA defined by TEE was missed by transthoracic echocardiography in 92 patients (47%). As judged from TEE, ASA involved the entire septum in 100 patients (51%) and was limited to the fossa ovalis in 95 (49%). ASA was an isolated structural defect in 62 patients (32%). In 106 patients (54%), ASA was associated with interatrial shunting (atrial septal defect, n = 38; patent foramen ovale, n = 65; sinus venosus defect, n = 3). In only 2 patients (1%), thrombi attached to the region of the ASA were noted. Prior clinical events compatible with cardiogenic embolism were associated with 87 patients (44%) with ASA; in 21 patients (24%) with prior presumed cardiogenic embolism, no other potential cardiac sources of embolism were present. Length of ASA, extent of bulging, and incidence of spontaneous oscillations were similar in patients with and without previous cardiogenic embolism; however, associated abnormalities such as atrial shunts were significantly more frequent in patients with possible embolism. CONCLUSIONS As shown previously, TEE is superior to the transthoracic approach in the diagnosis of ASA. The most common abnormalities associated with ASA are interatrial shunts, in particular patent foramen ovale. In this retrospective study, patients with ASA (especially with shunts) showed a high frequency of previous clinical events compatible with cardiogenic embolism; in a significant subgroup of patients, ASA appears to be the only source of embolism, as judged by TEE. Our data are consistent with the view that ASA is a risk factor for cardiogenic embolism, but thrombi attached to ASA as detected by TEE are apparently rare.
The interaction between glucose and cytokinin signaling in controlling Arabidopsis thaliana seedling root growth and development

ABSTRACT Cytokinin (CK) and glucose (GLC) control several common responses in plants. There is an extensive overlap between CK and GLC signal transduction pathways in Arabidopsis. Physiologically, both GLC and CK could regulate root length in light. CK interacts with GLC via HXK1 dependent pathway for root length control. Wild-type (WT) roots cannot elongate in the GLC free medium while CK-receptor mutant ARABIDOPSIS HISTIDINE KINASE4 (ahk4) and type B ARR triple mutant ARABIDOPSIS RESPONSE REGULATOR1, 10,11 (arr1, 10,11) roots could elongate even in the absence of GLC as compared with the WT. The root hair initiation was also found defective in CK signaling mutants ahk4, arr1,10,11 and arr3,4,5,6,8,9 on increasing GLC concentration (up to 3%); and lesser number of root hairs were visible even at 5% GLC as compared with the WT. Out of 941 BAP regulated genes, 103 (11%) genes were involved in root growth and development. Out of these 103 genes, 60 (58%) genes were also regulated by GLC. GLC could regulate 5736 genes, which include 327 (6%) genes involved in root growth and development. Out of these 327 genes, 60 (18%) genes were also regulated by BAP. Both GLC and CK signaling cannot alter root length in light in auxin signaling mutant AUXIN RESPONSE3/INDOLE-3-ACETIC ACID17 (axr3/iaa17) suggesting that they may involve auxin signaling component as a nodal point. Therefore CK- and GLC- signaling are involved in controlling different aspects of root growth and development such as root length, with auxin signaling components working as downstream target.
High-Incidence of Human Adenoviral Co-Infections in Taiwan

Background Respiratory infections caused by adenovirus (HAdV) are common year round. Recently, a significant increase of adenoviral infections was observed in Taiwan. Objective To understand the prevalence and molecular epidemiology of respiratory adenovirus circulating in Taiwan for the past decade. Study Design One hundred and twenty-six human adenoviruses, isolated between 2002 to 2011, were characterized via DNA sequencing of the hexon and fiber genes. The nucleotide sequences were then compared by phylogenetic analysis. Results HAdV-B3 accounted for 64.3% (81/126) and peaked almost every year, whereas the sequences of hexon and fiber genes of HAdV-B3 were highly conserved in different years. A high incidence of co-infection of adenoviruses was observed (19.0%, 24/126); HAdV-B3 co-infected with HAdV-C2 was the most common combination (58.3%, 14/24). An additional interesting finding of repeated infection was noted in 10 children, all of whom showed first infection with adenovirus species HAdV-C, followed by species HAdV-B or HAdV-E. Conclusions HAdV-B3 was the predominant type of respiratory adenovirus circulating in Taiwan over the past ten years. This merits further attention for vaccine development. Furthermore, the observed high-incidence of adenoviral co-infections along with repeated infections found in our study provides important epidemiological insights into adenovirus infections.
Role of Eotaxin-3 in Chronic Rhinosinusitis with Nasal Polyps

Chronic rhinosinusitis with nasal polyps (CRSwNP) is connected to a chronic inflammatory process with the activation of different immune components. Eotaxin-3, acidic mammalian chitinase (AMCase), and interleukin (IL)–13 as focal immune factors have been detected in CRSwNP, but their importance and relationship are still being investigated. This study aims to detect the expression of AMCase, IL-13, and eotaxin-3 in the mRNA level and investigate their roles and relationships in CRSwNP. Twenty-four subjects with eosinophilic CRSwNP and 11 controls were included in the study. Tissues were obtained by endoscopic sinus surgery. Target genes were detected by real-time reverse transcription–polymerase chain reaction. AMCase, eotaxin-3, and IL-13 were detected in all CRSwNP and controls. The expression of AMCase, eotaxin-3, IL-13, and mRNA was significantly higher in patients with CRSwNP than in the control group. There was a significantly positive correlation not only between AMCase and eotaxin-3 but also between IL-13 and eotaxin-3 in CRSwNP. Increased AMCase, IL-13, and eotaxin-3 might lead to the Th2 inflammatory cascade reaction.

Interferon-γ production by neutrophils during bacterial pneumonia in mice.

RATIONALE Neutrophils are usually the first circulating leukocytes to respond during bacterial pneumonia. Their expression of oxidants, proteases, and other mediators present in granules is well documented, but their ability to produce mediators through transcription and translation after migration to an inflammatory site has been appreciated only more recently. Interferon (IFN)-γ is a cytokine with many functions important in host defense and immunity. OBJECTIVES To examine the expression and function of IFN-γ in bacterial pneumonias. METHODS IFN-γ mRNA and protein were measured in digests of mouse lungs with 24-hour bacterial pneumonia. Bacterial clearance was studied with IFN-γ-deficient mice. MEASUREMENTS AND MAIN RESULTS Streptococcus pneumoniae and Staphylococcus aureus each induce expression of IFN-γ mRNA and protein by neutrophils by 24 hours. Only neutrophils that have migrated into pneumonic tissue produce IFN-γ. Deficiency of Hck/Fgr/Lyn, Rac2, or gp91(phox) prevents IFN-γ production. IFN-γ enhances bacterial clearance and is required for formation of neutrophil extracellular traps. In contrast, Pseudomonas aeruginosa and Escherichia coli induce production of IFN-γ mRNA but not protein. During pneumonia induced by E. coli but not S. pneumoniae, neutrophils produce microRNAs that target the 3' untranslated region of the IFN-γ gene. CONCLUSIONS S. pneumoniae and S. aureus, but not P. aeruginosa and E. coli, induce emigrated neutrophils to produce IFN-γ within 24 hours. Hck/Fgr/Lyn, Rac2, and NADPH oxidase are required for IFN-γ production. IFN-γ facilitates bacterial clearance at least in part through regulating formation of neutrophil extracellular traps. Differential expression by neutrophils of microRNAs that target the 3' untranslated region of the IFN-γ gene may contribute to the pathogen-specific regulation of translation.
Australia Inside/Out: The Corporate Governance System of the Australian Listed Market

This article concerns the classification of the corporate governance system of Australia’s listed market. Claims are often made that it is an outsider system of ownership and control, similar to that of the UK and the US. Through an examination of share ownership patterns, institutional investor activism, private rent extraction, the market for corporate control and blocks to information flow, this article argues that the corporate governance system of Australia’s listed market in fact has many of the characteristics associated with insider systems. The misclassification of the corporate governance system of Australia’s listed market has significant impacts for the general classification of insider and outsider systems, as it may be an example of an insider system converging to an outsider system. The misclassification also has significant impacts for the Australian reform agenda, as reforms based on the assumption that the Australian listed market has an outsider system of corporate governance may be inappropriate and damaging.
Surface impedances for planar conductors in volume discretization methods without frequency limitations

Surface impedance boundary conditions (SIBC) for lossy metal layers are presented that are not limited to the frequency range in which a metal layer is thicker than several skin depth. A metal layer is considered as a TEM transmission line so that the SIBCs can be obtained as the input impedances of an open ended and a short circuited transmission line, respectively. The SIBCs are verified for a MMIC microstrip line and a coplanar waveguide.
Endothelin-1 Levels and Conduit Artery Mechanical Properties in End-Stage Renal Disease

Background: Endothelial cell (EC) dysfunction markers are increased in end-stage renal disease (ESRD). The present study focused on the relationship between EC markers, conduit artery wall mechanics and hemodynamics in ESRD. Methods: In 29 ESRD patients and 16 controls, brachial artery diameter, distension, and wall thickness was measured and circumferential wall stress (CWS) calculated. Shear stress was determined with a shear rate-estimating system. Furthermore, von Willebrand factor antigen (vWF) and endothelin-1 (ET-1) levels were measured. Results: vWF (p = 0.002) and ET-1 (p < 0.001) were higher in ESRD patients and vWF was related to ET-1 (r = 0.70, p = 0.005). Peak (p = 0.001) and mean shear stress (p = 0.003) were significantly lower in ESRD patients, and ET-1 showed an inverse log linear relation with both (peak: r = –0.59, p = 0.016; mean: r = –0.64, p = 0.007). Also, ET-1 was log linearly related to CWS (r = 0.58, p = 0.014). Conclusion: These results indicate that, in ESRD, conduit artery shear stress is lower, which might be secondary to an increased peripheral vascular resistance caused by higher ET-1 levels.
Expression of two forms of prolactin receptor in rat ovary and liver.

The screening of a size-selected cDNA library from the ovary revealed the existence of a second form of PRL receptor in the rat. The polypeptide sequence deduced from cDNAs has a much longer cytoplasmic domain (357 amino acids) than the form previously identified in the liver (57 amino acids). Nucleotide sequence analysis and comparison with rabbit, mouse, and human PRL receptor cDNAs suggests that the two forms of rat PRL receptor result from alternative splicing of a primary transcript. Complementary DNAs encoding the long form of the receptor were also found in a library prepared from estradiol-treated rat liver, although they represent a minor fraction of total PRL receptor cDNAs obtained from this tissue. DNA polymerase chain reaction amplification of cDNA confirmed the presence of the two receptor forms in both the ovary and liver. Northern analysis, using probes that specifically hybridize with either form of mRNA, indicates a major transcript of 1.8 kilobases (kb) in estradiol-treated liver, which encodes the receptor with a short cytoplasmic domain, while the long form of the receptor is encoded by mRNAs of 2.5 and 3 kb. In the ovary, a complex pattern of hybridization to multiple mRNAs (1.8-5.5 kb) is obtained with the probe specific to the long form, and essentially only a 5.5-kb mRNA is obtained with the probe specific to the short form. The predicted size of the mature form of the long PRL receptor (PRL-R2) is 591 amino acid residues. (ABSTRACT TRUNCATED AT 250 WORDS)
Evolution of Enterohemorrhagic Escherichia coli Hemolysin Plasmids and the Locus for Enterocyte Effacement in Shiga Toxin-Producing E. coli

ABSTRACT This study assessed the diversity of the enterohemorrhagicEscherichia coli (EHEC) hemolysin gene (ehxA) in a variety of Shiga toxin-producing E. coli (STEC) serotypes and the relationship between ehxA types and virulence markers on the locus for enterocyte effacement (LEE). Restriction fragment length polymorphism of the ehxA gene and flanking sequences and of the E. coli attaching and effacing (eae) gene was determined for 79 EHEC hemolysin-positive STEC isolates of 37 serotypes. Two main groups of EHEC hemolysin sequences and associated plasmids, which corresponded to the eae-positive and the eae-negative isolates, were delineated. Comparisons of the ehxA gene sequences of representative isolates of each group showed that this gene and the rest of the EHEC hemolysin operon are highly conserved. Digestion of anehxA PCR product with the restriction endonucleaseTaqI showed a unique restriction pattern foreae-negative isolates and another one for isolates of serotypes O157:H7 and O157:NM. A conserved fragment of 5.6 kb with four potential open reading frames was identified on the EHEC hemolysin plasmid of eae-positive STEC. Phylogenetic analysis of a subset of 27 STEC isolates, one enteropathogenic E. coliisolate, and a K-12 reference isolate showed thateae-positive STEC isolates all belong to a single evolutionary lineage and that the EHEC hemolysin plasmid and theehxA gene evolved within this lineage without recent horizontal transfer. However, the eae gene and the LEE appear to have been transferred horizontally within this STEC lineage on several occasions. The reasons for the lack of transfer or maintenance of the LEE in other STEC lineages are not clear and require further study.
Bilateral Simultaneous Facial Nerve Palsy: Clinical Analysis in Seven Cases

Objective: To analyze clinical manifestations and prognosis of bilateral simultaneous facial nerve palsy (BS-FNP). Study Design: Retrospective case review with current follow-up wherever possible. Setting: Tertiary referral centers. Patients: Patients (n = 7; 4 women and 3 men; mean age, 37 yr; range, 18-58 yr) diagnosed with BS-FNP at the time of their first visit. Intervention: Therapy with systemic corticosteroids and antiviral agents and outpatient follow-up for 1 month to 4 years after discharge. Main Outcome Measure: Assessment of recovery from FNP using the House-Brackmann grading system. Results: The occurrence rate of BS-FNP of total FNP cases for the past 10 years was 0.4%. All patients showed palsy more severe than House-Brackmann Grade IV and similar grades of FNP bilaterally. Patients complained of the involvement of the other side within 1 to 6 days of the involvement of 1 side (mean period, 3.4 d). Bell's palsy was the most common cause (5 of 7; 71.4%), the other 2 being infectious mononucleosis and Ramsay Hunt syndrome zoster sine herpete (1 of 7; 14.3% each). Although most patients recovered completely within 1 to 6 months, 1 with a positive Varicella zoster virus immunoglobulin M titer showed bilateral House-Brackmann Grade II FNP after recovery. No recurrence was noted during the follow-up period. Conclusion: Bell's palsy is the most common cause of BS-FNP in authors' centers. Although BS-FNP may show more severe paralysis, the overall prognosis in most cases is as good as that in unilateral FNP, excluding life-threatening or traumatic cases. Differential diagnosis is very important because the treatment outcome of BS-FNP depends on the cause.
Developmental pathway genes and neural plasticity underlying emotional learning and stress-related disorders

The manipulation of neural plasticity as a means of intervening in the onset and progression of stress-related disorders retains its appeal for many researchers, despite our limited success in translating such interventions from the laboratory to the clinic. Given the challenges of identifying individual genetic variants that confer increased risk for illnesses like depression and post-traumatic stress disorder, some have turned their attention instead to focusing on so-called “master regulators” of plasticity that may provide a means of controlling these potentially impaired processes in psychiatric illnesses. The mammalian homolog of Tailless (TLX), Wnt, and the homeoprotein Otx2 have all been proposed to constitute master regulators of different forms of plasticity which have, in turn, each been implicated in learning and stress-related disorders. In the present review, we provide an overview of the changing distribution of these genes and their roles both during development and in the adult brain. We further discuss how their distinct expression profiles provide clues as to their function, and may inform their suitability as candidate drug targets in the treatment of psychiatric disorders.
A peripheral blood T cell clone is a prognostic marker in mycosis fungoides.

giving rise to the dominant and recessive incidence values (Fine et al, 1999). The new mutation rate for any of the forms of EB has not been calculated; however, a number of sporadic cases of DEB have been analyzed for mutations in the COL7A1 gene and are presumed to result from germline mosaicism (Rouan et al, 1998; Hashimoto et al, 1999; Lee et al 2000). Continued elucidation of the mutations involved in all forms of EB will allow us to further understand the relative numbers of new mutations, and to correlate type of mutation and pattern of inheritance. The carrier incidence information provided in Table I should enable genetics professionals to accurately calculate the risk of recurrence to individual family members based on the family history and provide up-to-date risk estimates that will facilitate accurate counselling of extended families at risk.
Comments on Obstfeld and Rogoff's "the Six Major Puzzles in International Macroeconomics: Is There a Common Cause?"

The paper offers comments on Obstfeld and Rogoff (2000). The comments primarily focus on three issues: (a) How do we reconcile the numerical examples of OR, which show quantitatively plausible resolutions to the major puzzles arising from costs of trade, with previous studies that have found trade costs do not get us very far? (b) Does the solution proposed by OR solve the puzzles at the expense of introducing new puzzles? That is, does their solution have counterfactual implications for other economic relationships? (The prime example of what I have in mind here is what OR call the Backus-Smith puzzle'.) (c) Some of the problems connected with points (a) and (b) can be rectified by moving away from the assumption of complete asset markets. But, then, how do we assess how much of the solution to the puzzle is coming from trade costs versus capital-market imperfections?
Spoiling for a Fight: B Lymphocytes As Initiator and Effector Populations within Tertiary Lymphoid Organs in Autoimmunity and Transplantation

Tertiary lymphoid organs (TLOs) develop at ectopic sites within chronically inflamed tissues, such as in autoimmunity and rejecting organ allografts. TLOs differ structurally from canonical secondary lymphoid organs (SLOs), in that they lack a mantle zone and are not encapsulated, suggesting that they may provide unique immune function. A notable feature of TLOs is the frequent presence of structures typical of germinal centers (GCs). However, little is known about the role of such GCs, and in particular, it is not clear if the B cell response within is autonomous, or whether it synergizes with concurrent responses in SLOs. This review will discuss ectopic lymphoneogenesis and the role of the B cell in TLO formation and subsequent effector output in the context of autoimmunity and transplantation, with particular focus on the contribution of ectopic GCs to affinity maturation in humoral immune responses and to the potential breakdown of self-tolerance and development of humoral autoimmunity.
Hypotensive effect of freeze-dried garlic (Allium Sativum) sap in dog.

Watary extract of ALLIUM SATIVUM when administered Intravenously (I.V.) to NORMOTENSIVE dogs, produced a significant fall in their mean blood pressure. This effect was not antagonized by atropine or antihistamines. The extract increased the activity of Isolated Guinea Pig Ileum preparation. This effect of A Sativum was blocked by Diamentane (JPMA 31:12, 1981).
