The generalized endotoxic principle

Bacterial lipopolysaccharides (endotoxins, LPS) belong to the most potent immunostimulators in mammals. The endotoxic principle of LPS is located in its lipid A moiety, which for Escherichia coli‐type LPS consists of a hexaacylated diphosphoryl diglucosamine backbone. This lipid A adopts a cubic inverted aggregate structure from which a conical shape of the molecule can be deduced, whereas the tetraacyl lipid A precursor IVa adopts a cylindrical shape and is endotoxically inactive, but antagonizes active LPS. We hypothesize that non‐lipid A amphiphiles with similar physicochemical properties of amphiphilicity, charge, and shape, might mimic the respective lipid A. To test this hypothesis, phospholipid‐like amphiphiles with six acyl chains attached to a bisphosphorylated serine‐like backbone of varying length replacing the diglucosamine backbone were synthesized. The compound with a short backbone fulfills all criteria of an endotoxic agonist, and that with longbackbone fulfills those of an antagonist. This holds true for the human as well as for the murine system. Interestingly, these compounds are inactive in the Limulus amebocyte lysate test which is specific for LPS diglucosamine backbone. These results define a general endotoxic principle and, furthermore, provide new insights into an understanding of early steps of endotoxin action.
Evaluation of post-treatment health-related quality of life (HRQoL) among tuberculosis patients.

BACKGROUND Health-related quality of life (HRQoL) measures the impact of a disease by assessing the health status of patients. OBJECTIVE To assess the HRQoL of tuberculosis (TB) patients one year after treatment completion. METHODS Patients registered under the TB control programme from July 2002 to June 2003 in a TB Unit in south India were interviewed one year after successful completion of treatment. Data on HRQoL were collected using the SF-36 questionnaire, which covers physical, mental and social well-being components. Data on economic well-being were also collected. Scores were given for all domains. RESULT Of 436 TB patients interviewed, the mean scores for social, physical, mental and economic well-being were respectively 84, 74, 68 and 62 on a scale of 100. The well-being scores were significantly related to age, sex, education, employment and persistent symptoms. There was a significant association between economic and social well-being. CONCLUSION This study suggests that the HRQoL of TB patients one year after successful completion of treatment under the TB control programme was normal for most of the domains studied and was associated with age, literacy and employment, income, smoking, alcoholism and persistence of symptoms.
Heavy Drinking as a Risk Factor for Depression and Dementia in Elderly Men

A random community sample of subjects aged 65 and over was re-interviewed after three years by psychiatrists using the GMS and HAS. The relationship between drinking history and current psychiatric morbidity was examined. Men with a history of heavy drinking for five years or more at some time in their lives were found to have a greater than fivefold risk of suffering from a psychiatric disorder at the time of the interview. Among this group past alcohol consumption was significantly higher for those with a current psychiatric diagnosis compared with those who were well. This association between heavy alcohol consumption in earlier years and psychiatric morbidity in later life is not explained by current drinking habits.
Annular-Ring and Circular-Disc Microstrip Antennas with & without Air Gaps

A systematic study is first presented on the impedance bandwidth characteristics of the first few modes of the annular ring and the circular disc microstrip antennas. It is then established, both experimentally & theoretically, that the resonant frequencies can be tuned and the bandwidths widened by introducing an adjustable air gap between the substrate and the ground plane.
Angiotensin-converting enzyme inhibition suppresses plasminogen activator inhibitor-1 expression in the neointima of balloon-injured rat aorta.

BACKGROUND Plasminogen activator inhibitor-1 (PAI-1), an important regulator of fibrinolysis and extracellular matrix turnover, has been implicated in a number of vascular diseases. Studies demonstrating angiotensin II (Ang II) to be a potent stimulator of PAI-1 expression in cultured vascular cells suggests that the renin-angiotensin system may modulate vascular PAI-1 expression. METHODS AND RESULTS We examined the effects of the ACE inhibitor captopril on PAI-1 expression in control and balloon-injured rat aorta. Northern blot analysis demonstrated that aortic PAI-1 mRNA expression was 7.6-fold elevated 3 hours (P<.05) after balloon injury, back to baseline at 2 days, increased again at 4 days, and by 7 days after balloon injury was 3.2-fold elevated (P<.05) when compared with control. In captopril-treated rats, the induction of PAI-1 expression by balloon injury was significantly suppressed by 44% (P<.05) in the 7 day group but was not altered in the 3-hour group. Captopril also reduced baseline aortic PAI-1 mRNA. In situ hybridization and immunohistochemistry revealed dense PAI-1 staining of 7-day neointima in untreated rats and a dramatic decrease in PAI-1 in neointima of captopril-treated rats. CONCLUSIONS This report demonstrates that balloon injury results in both a rapid ACE inhibitor-independent induction of aortic PAI-1 expression and a later increase in PAI-1 in the neointima that is significantly suppressed by captopril. This provides the first evidence that the renin-angiotensin system regulates neointimal PAI-1 expression and that ACE inhibitors can reduce PAI-1 in the vessel wall in vivo.
Review of Current Theories for Abdominal Aortic Aneurysm Pathogenesis

Atherosclerotic plaques are a feature of abdominal aortic aneurysms (AAAs). Atherosclerosis and AAA appear to share similar risk factors. These observations have led to the conclusion that AAAs are a consequence of advanced atherosclerosis. This review explores current theories regarding the pathogenesis of AAA and their implications for treatment. A systematic literature search was conducted using the search terms abdominal aortic aneurysm, atherosclerosis, pathogenesis, and systemic disease. Articles were categorized according to the association of AAAs with atherosclerosis, arteriomegaly, peripheral aneurysm, systemic expression, genetics, autoimmunity, oxidative stress, and systemic disease. Twenty-nine articles reporting changes in the systemic vasculature associated with AAA and 12 articles examining the shared risk factor hypothesis were identified. There is insufficient evidence to confirm that AAAs are the result of advanced atherosclerosis. The bulk of evidence points to AAA disease being a systemic disease of the vasculature, with a predetermined genetic susceptibility leading to a phenotype governed by environmental factors.
The Effectiveness of a CNS‐led Community‐based COPD Screening and Intervention Program

Purpose/Objectives The purpose of this study was to evaluate the effectiveness of a screening program in identifying undiagnosed individuals with chronic obstructive pulmonary disease (COPD). Theoretical Rationale Underdiagnosis of COPD is common. Symptoms do not usually become apparent until the disease is advanced. Consequently, by the time a diagnosis of COPD is made, based on symptoms, the individual has often lost up to 50% or more of their original lung capacity. Early diagnosis and intervention has been demonstrated to have an impact in slowing the progression of the disease. The study was based on the premise that when individuals become self-aware of their risk factors related to disease, they are more likely to change their behaviors. The Transtheoretical Model describes how individuals move through various stages of change and how they can be helped in transitioning from one stage to another. Description of the Project Subjects (n = 243) were recruited via letter, newspaper, and physician referral. The screening program consisted of (1) pulmonary function testing using a handheld spirometry device, (2) education about the test results and COPD, and (3) smoking cessation counseling. Current smokers and those found to have obstruction were contacted at 8 to 12 weeks after screening. Outcome Results indicated that 209 (86%) of participants were at risk for developing COPD as evidenced by current or past smoking status. Mild to moderate stage obstructive disease was found in 55 subjects (23%). Of 61 subjects contacted after the screening, 29 smokers (47%) indicated they had stopped smoking, were in the process of quitting, or were seriously considering quitting. Conclusions Results support the use of a community-screening program to identify and help modify risk factors for COPD. Implications for Nursing Practices This project provides an example of how a clinical nurse specialist (CNS) can exercise all the spheres of CNS influence: the patient/client sphere, the nursing personnel sphere, and the organization sphere. In addition, the COPD screening project demonstrated how a CNS can successfully lead and direct a community initiative and influence others in changing behavior to enhance their state of health.
8-hydroxy-deoxyguanosine levels in gingival crevicular fluid and saliva in patients with chronic periodontitis after initial periodontal treatment.

BACKGROUND This study evaluates the effects of initial periodontal treatment on the gingival crevicular fluid (GCF) and salivary levels of 8-hydroxy-deoxyguanosine (8-OHdG) as a marker of oxidative deoxyribonucleic acid (DNA) damage in patients with chronic periodontitis (CP). METHODS At baseline, clinical parameters were determined and GCF and saliva samples were obtained from 24 patients with CP and 24 individuals with clinically healthy periodontium. GCF, saliva samples, and clinical periodontal measurements were repeated at day 10, 1 month, and 3 months following initial periodontal therapy in patients with CP. 8-OHdG levels of GCF and saliva samples were investigated by using an enzyme-linked immunosorbent assay. RESULTS Statistically significant higher 8-OHdG levels of GCF and a significant decrease after initial periodontal therapy were determined in the CP group (P <0.001). A significant positive correlation was found between 8-OHdG levels of GCF and clinical periodontal measurements (P <0.001). However, salivary levels of 8-OHdG did not differ between groups or during initial periodontal therapy (P >0.05). CONCLUSIONS This study reveals that DNA injury and oxidative stress increase in tissue cells and especially in periodontal pockets in patients with CP, and the periodontal treatment results in a significant decrease of 8-OHdG levels in the GCF samples. To the best of our knowledge, this study evaluates for the first time, 8-OHdG levels in GCF, which is shown to be more useful as a biomarker than saliva. 8-OHdG was found to be important and may reveal the severity of periodontal disease and the effect of periodontal therapy.
Evidence for a novel regulatory pathway for herpes simplex virus gene expression in trigeminal ganglion neurons

Thymidine kinase (TK)-negative (TK-) mutant strains of herpes simplex virus type 1 (HSV-1) show reduced expression of alpha and beta viral genes during acute infection of trigeminal ganglion neurons following corneal infection (M. Kosz-Vnenchak, D. M. Coen, and D. M. Knipe, J. Virol. 64:5396-5402, 1990). It was surprising that a defect in a beta gene product would lead to decreased alpha and beta gene expression, given the regulatory pathways demonstrated for HSV infection of cultured cells. In this study, we have examined viral gene expression during reactivation from latent infection in explanted trigeminal ganglion tissue. In explant reactivation studies with wild-type virus, we observed viral productive gene expression over the first 48 h of explant incubation occurring in a temporal order (alpha, beta, gamma) similar to that in cultured cells. This occurred predominantly in latency-associated transcript-positive neurons but was limited to a fraction of these cells. In contrast, TK- mutant viruses showed greatly reduced alpha and beta gene expression upon explant of latently infected trigeminal ganglion tissue. An inhibitor of viral TK or an inhibitor of viral DNA polymerase greatly decreased viral lytic gene expression in trigeminal ganglion tissue latently infected with wild-type virus and explanted in culture. These results indicate that the regulatory mechanisms governing HSV gene expression are different in trigeminal ganglion neurons and cultured cells. We present a new model for viral gene expression in trigeminal ganglion neurons with implications for the nature of the decision process between latent infection and productive infection by HSV.
A note on paracompact spaces

Let us quickly recall the definitions of the terms which are used in the statement of Theorem 1, and which will be used throughout this paper. Let X be a topological space. A collection <R of subsets of X is called open (resp. closed) if every element of "R. is open (resp. closed) in X. A covering of X is a collection of subsets of X whose union is X; observe that in this paper a covering need not be open. If 'R. is a covering of X, then by a refinement of 'R we mean a covering V of X such that every element of V is a subset of some element of 'R. A collection <R of subsets of X is locally finite if every x£X has a neighborhood which intersects only finitely many elements of <R. Finally, X is paracompact [3, p. 66] if it is Hausdorff, and if every open covering of X has an open, locally finite refinement. (Metric spaces and compact Hausdorff spaces are paracompact (cf. [il] and [3]), and every paracompact space is normal [3]. ) In §2 we prove Theorem 1, after first obtaining some preliminary lemmas, the first of which may have some independent interest. In §§2 and 3, we derive some of the consequences of Theorem 1 ; §2 deals with the relation of paracompactness to other topological properties, and §3 deals with subsets and cartesian products of paracompact spaces.
Effectiveness of MP29-02 for the treatment of allergic rhinitis in real-life: results from a noninterventional study.

The efficacy of MP29-02 (a novel intranasal formulation of azelastine hydrochloride and fluticasone propionate in an advanced delivery system) has been well established in controlled clinical trials. This study was designed to assess the use of MP29-02 and its effectiveness in routine clinical practice. This was a German multicenter, prospective, noninterventional study, including 1781 allergic rhinitis (AR) patients. Eligible patients (i.e., acute AR symptoms and visual analog scale [VAS] score >50 mm) were included, assigned MP29-02 at baseline, and reassessed after ∼14 days. Patients assessed symptom control using a VAS from 0 (not at all bothersome) to 100 mm (very bothersome) in the morning before MP29-02 use, on days 0, 1, 3, and 7 and after ∼ 14 days. Patients' perceived levels of disease control were assessed on day 3. The Youden index determined patient-reported VAS score cutoffs on day 3 for "well controlled" and "partly controlled. " MP29-02 reduced the VAS score from 75.4 mm (SD = 17.2) at baseline to 21.3 mm (SD = 18.3) by the last visit, a shift of 54.1 mm (SD = 24.6). One in every two patients felt their symptoms were well controlled at day 3. This perception of well-controlled symptoms at day 3 corresponded to an optimal VAS cutoff of 36 mm. On average, patients treated with MP29-02 crossed this well-controlled VAS cutoff by last visit. Similar results were found in adolescents, adults, and older adults, in those with perennial AR (PAR), seasonal AR (SAR), or PAR + SAR and in those with more and less severe disease. MP29-02 provides effective and rapid symptom control across all age groups in a real-life setting with responder rates higher than those observed in controlled clinical trials, supporting MP29-02's position as the drug of choice for the treatment for AR.
Suitability of the IDMS-Traceable MDRD Equation Method to Estimate GFR in Early Postoperative Renal Transplant Recipients

Background/Aims: Accurate measurement of glomerular filtration rate (GFR) is critical for the management of kidney transplant recipients. Comparison of creatinine and cystatin C in renal transplant recipients gave conflicting results. We aimed to compare the performance of creatinine- and cystatin C-based equations and creatinine clearance in 102 early postoperative Korean renal transplant patients. Methods: We measured 51Cr-EDTA clearance using a 2-compartment model and considered this the reference GFR. Then, we estimated GFR using 13 creatinine- and 7 cystatin C-based equations. Serum creatinine value was calibrated to isotope-dilution mass spectrometry (IDMS). Results: The mean reference GFR was 76.77 ± 17.01 ml/min/1.73 m2. The IDMS-traceable MDRD (IDMS-MDRD) equation had the highest accuracy (94.12 within 30% of the reference; 99.02 within 50% of the reference) with a bias of 0.33 ml/min/1.73 m2 and a precision of 12.57 ml/min/1.73 m2. The Mayo Clinic equation also performed well (92.16% within 30% of the reference; 99.02% within 50% of the reference; bias: –0.19 ml/min/1.73 m2). As for cystatin C-based equations, the Filler equation had the least bias (0.03 ml/min/1.73 m2) but low accuracy (78.43% within 30% of the reference). Conclusions: We conclude that the IDMS-MDRD equation provided the best estimate of GFR in our early postoperative Korean renal transplant patients.
Neurologic Abnormalities in Infantile Autism

Neuroanatomic, pathologic, and neurobehavioral studies point to a cerebellar and parietal abnormality in autism. We used a standardized protocol to examine neurologic function in 28 pediatric autistic subjects and 24 pediatric normal healthy volunteer controls. As a group, the autistic subjects had quantitative measures from magnetic resonance imaging suggesting hypoplasia or hyperplasia of the cerebellar vermis, as well as measurements of posterior corpus callosum suggesting abnormalities of posterior cortex. In groups of tests that reflect cerebellar and parietal function, the neurologic abnormalities detectable by clinical examination were significantly greater for autistic subjects than for normal controls. These studies confirm that the structural and behavioral deficit in autism does lead to abnormalities that can be detected on the clinical neurologic examination. (J Child Neurol 1996; 11:84-92).
Transcatheter aortic valve implantation, patient selection process and procedure: two centres' experience of the intervention without general anaesthesia.

INTRODUCTION transcatheter aortic valve implantation (TAVI) is an emerging technique for the treatment of aortic stenosis. With the advent of percutaneous suture devices for the access point and prosthesis delivery systems of smaller diameter, TAVI has become a truly percutaneous procedure: percutaneous aortic valve replacement (PAVR). Thus, PAVR may be conducted without general anaesthesia (GA). METHODS We report two centres' experience from PAVR without GA. CoreValve aortic bioprostheses were utilised. The patient selection process and PAVR procedure are described in detail. RESULTS a total of 30 patients (pts) were treated with PAVR. In 4 pts correction of the initial malposition of the prosthesis required a special technique (2 pts: "snare"; 2 pts: "removing and reinserting"). At 1-month follow up, haemodynamic and clinical improvements were observed: left ventricular ejection fraction increased from 50.8 ± 9.3% to 54.3 ± 8.3% (p=0.02); peak aortic valve gradient decreased from 90.3 ± 26.4 mmHg to 14.8 ± 9.7 mmHg, (p<0.001); NYHA functional class decreased from 3.53 ± 0.93 to 1.45 ± 0.94 (p<0.001). Overall 1-month mortality was 3.3% (1 patient died). CONCLUSION PAVR without general anaesthesia is a feasible technique, however the role of anaesthesiologists is still important.
Robust feed forward tracking control system for using zero phase low-pass filter

In next generation optical disk system, the disk rotation speed becomes nearly equal to 10000[rpm]. Since the optical disk systems have a radial run-out, its phenomenon becomes the periodic disturbance whose bandwidth depends on the disk rotational speed. Hence, the tracking control system of next generation optical disk recording system should have the robust precision control against the high speed periodic disturbance whose rotational speed is nearly equal to 10000[rpm]. Moreover, this tracking servo system should have and the wide bandwidth. For this purpose, the feedforward controllers such as Zero Error Phase Tracking (ZPET) control and Perfect Tracking Control (PTC), have been proposed the tracking control for the mass strage system. However, for the next generation optical disk system, it is sometimes diffcult to realize the feedforward controller for suppression of high speed periodic disturbance. This paper proposes the structure of feedforward controller based on the prediction of tracking error. Moreover, the total control structure realizes the proposed feedforward controller with a new robust feedback control system. The experiment results point out that the proposed system well regulates the high precision tracking control on condition of the disk rotation speed 8000[rpm], which is equal to the rotation speed of 40 X speed on CD system.
Natalizumab discontinuation and disease restart in pregnancy: a case series

The humanized monoclonal alpha4‐integrin antibody Natalizumab (NTZ) (Tysabri©, Biogen Idec, Cambridge, MA, USA) has shown to be effective in multiple sclerosis (MS) therapy; however, the interruption of the drug has been related to a disease restart. This risk has to be carefully considered in case of accidental or desired pregnancies.
Parents' and Adolescents' Perceptions of a Strong Family

Perceptions of family strengths of 40 parents and 20 adolescents were investigated by means of semistructured interviews and Likert-type ratings on commitment, appreciation, spending time together, communication patterns, religious values, and crisis management. Significant differences were found between the perceptions of parents and adolescents for the family characteristics of commitment, time spent together, and crisis management. Although family strength correlated positively with all six identified characteristics, time spent together and appreciation for each other had the highest correlation with family strength. This result supports the notion that sufficient quality time together may be a prerequisite for well-being in family relationships.
Empirical research on internal control disclosure in China —based on management's standpoint

The paper stands on companies' management, by constructing panel data model to analyse the factors to management's internal control disclosure, finds financial status is a significant impact on the behavior of management's disclosure; while the role of corporate governance is smaller than we expected although there was significant; time effect is particularly significant in the analysis, which provides empirical support for the effect of the policy of internal control disclosure issued by the state, which has certain reference.
Optimized Multiplier Based upon 6-Input Luts and Vedic Mathematics

— A new approach has been used for optimized design of multipliers based upon the concepts of Vedic mathematics. The design has been targeted to state-of-the art field-programmable gate arrays (FPGAs). The multiplier generates partial products using Vedic mathematics method by employing basic 4x4 multipliers designed by exploiting 6-input LUTs and multiplexers in the same slices resulting in drastic reduction in area. The multiplier is realized on Xilinx FPGAs using devices Virtex-5 and Virtex-6.Carry Chain Adder was employed to obtain final products. The performance of the proposed multiplier was examined and compared to well-known multipliers such as Booth, Carry Save, Carry ripple, and array multipliers. It is demonstrated that the proposed multiplier is superior in terms of speed as well as power consumption.
