An IR drop-driven placer for standard cells in a SOC design

A partition-based IR drop-driven algorithm is proposed for standard cell placement. Different cost functions for reducing IR drop are used in the horizontal cut and vertical cut partitioning processes. In addition to minimizing the total wire length, we balance the power consumption of the two partitions during the horizontal cut partitioning process. During the vertical cut partitioning process, we move the cells with higher power consumption closer to the power sources to reduce the maximum IR drop of the row. After placement is finished, we apply a greedy placement refinement process to further reduce the value of the maximum IR drop. Each standard cell row is modeled with an equivalent conductance model. Then the IR drop of each row is calculated and analyzed. We compare the placement generated by the proposed approach with the wire length-driven placement. On average, the proposed approach improves the value of maximum IR drop by 51%. Therefore, it reduces the need to add power straps on the chip and more routing resources are saved
Muscle hypertrophy in men and women.

It is widely believed that women experience less skeletal muscle hypertrophy consequent to heavy-resistance training than men. The purpose of this study was to test this hypothesis using both traditional indirect indicators as well as a direct measure of muscle size. Seven male experimental (ME), 8 female experimental (FE), and 7 control subjects were studied before and after a 16-wk weight training program, in which ME and FE trained 3 days.wk-1 at 70 to 90% of maximum voluntary contraction using exercise designed to produce hypertrophy of the upper arm and thigh. Strength increased significantly (P less than 0.05) in ME and FE, respectively, on elbow flexion (36.2 and 59.2%), elbow extension (32.6 and 41.7%), knee flexion (12.8 and 24.4%), and knee extension (28.8 and 33.9%) tests. Absolute changes were significantly greater in ME than FE in 2 of the 4 tests, whereas percentage changes were not significantly different. Substantial muscle hypertrophy occurred in the upper arms of both ME and FE as evidenced by significant increases in upper arm circumference (7.9 and 7.9%), bone-plus-muscle (B+M) cross-sectional area (CSA) estimated by anthropometry (17.5 and 20.4%), and muscle CSA determined from computed tomography scanning (15.9 and 22.8%). Changes by ME and FE were not significantly different, except for the absolute increase in estimated B+M CSA, which was significantly greater in ME (11.2 vs 7.4 cm2). No muscle hypertrophy occurred in the thigh of either ME and FE as evidenced by non-significant changes in thigh circumference (1.7 and 2.3%), B+M CSA (4.9 and 6.1%), and muscle CSA (2.9 and 2.9%). Changes by ME and FE in body weight, fat-free weight, and fat weight were not significant. (ABSTRACT TRUNCATED AT 250 WORDS)
Effect of exercise training on plasma visfatin and eotaxin levels.

OBJECTIVE Visfatin, a novel adipokine, was revealed to be associated with obesity and to have insulin-mimetic effect. Eotaxin, which is an important chemokine in asthma, was recently reported to be associated with obesity in mice and humans. We evaluated the effect of exercise training on plasma visfatin and eotaxin levels in association with cardiovascular risk factors. DESIGN Forty-eight non-diabetic Korean women were evaluated before and after a 12 week exercise program including aerobic exercise (45 min/session, 300 Kcal/day) and muscle strength training (20 min/session, 100 Kcal/day) five times per week. RESULTS Plasma visfatin concentrations were elevated in obese subjects (body mass index, BMI> or =25 kg/m2) when compared with non-obese subjects (16.4 +/- 13.4 ng/ml vs 7.7 +/- 5.2 ng/ml, P = 0.006), and eotaxin concentrations were elevated in subjects with central obesity (waist circumference, WC> or =80 cm) when compared with those without central obesity (73.6 +/- 17.8 pg/ml vs 64.2 +/- 4.2 pg/ml, P = 0.005). In multiple regression analyses, visfatin levels were associated with BMI (R2 = 0.255) and eotaxin levels were associated with WC and body weight (R2 = 0.307). After the exercise program, body weight, blood pressure, fasting glucose, and insulin resistance of participants were decreased. Furthermore, plasma visfatin levels were significantly decreased from 13.6 +/- 12.0 to 7.7 +/- 7.9 ng/ml (P = 0.026) and eotaxin levels were reduced from 72.0 +/- 16.7 to 66.9 +/- 14.2 pg/ml (P = 0.018). CONCLUSIONS Exercise training with weight loss induced a significant reduction of plasma visfatin and eotaxin levels in non-diabetic Korean women.
Improved diagnosis on a daily basis of enterovirus meningitis using a one‐step real‐time RT‐PCR assay

The detection of the enterovirus genome in cerebrospinal fluid (CSF) by PCR techniques has proved to be more sensitive than traditional cell culture for the diagnosis of enterovirus meningitis. However, PCR assays are time consuming and labor intensive, particularly if separate hybridization steps are used to confirm the specificity of positive findings. The aim of this study was to develop a one‐step real‐time RT‐PCR assay with LightCycler (LC) technology that was sensitive, rapid, and easy to perform in routine practice. The enterovirus detection limit was determined by testing 10‐fold limiting dilution series of cell culture stocks with the echovirus 25 (E‐25) prototype strain and with the third European Union Quality Control Concerted Action (EU‐QCCA) enterovirus proficiency panel. A total of 100 CSF specimens were investigated in a comparative study. With the E‐25 strain, the detection limit of the real‐time assay was 286 TCID50/ml (50% tissue culture infective dose). When samples of the EU‐QCCA panel were tested, our assay gave identical results (detection limit down to 3.6 TCID50/ml) to those of the reference laboratory, which used one‐step RT‐PCR assay. When CSF specimens were tested, there was a correlation between the real‐time assay and the conventional in‐house assay in 96 of 100 CSFs tested. This one‐step real‐time assay allows rapid enterovirus detection in CSF since results are obtained in 3 hr as against 36 hr with the “in‐house” RT‐PCR assay. This new assay is now being used in routine practice, and allows diagnosis on a daily basis. J. Med. Virol. 74:604–611, 2004. © 2004 Wiley‐Liss, Inc.
Expression of REIC/Dkk‐3 in normal and hyperproliferative epidermis

Abstract: Dickkopf (Dkk) family members are known as Wnt modulators involved in the development, cell growth/differentiation and cancer. REIC/Dkk‐3, which does not interfere with Wnt signalling, has been proposed to be a tumor suppressor gene, but its physiological function has remained unclear. In this study, we analysed the expression of REIC/Dkk‐3 in normal interfollicular epidermis (IFE) and hyperproliferative epidermis. REIC/Dkk‐3 was expressed in human and mouse IFE, being localized at the interface of upper spinous layer and granular layer. Skin cancer cell lines lost REIC/Dkk‐3 expression as reported previously. When we analysed patient samples, REIC/Dkk‐3 expression was down‐regulated in the hyperproliferative epidermis including skin cancers and non‐cancerous proliferative diseases. REIC/Dkk‐3 expression was also suppressed in the regenerative and inflammative epidermis of model mice. These findings will certainly contribute to the extension of studies on REIC/Dkk‐3.
Deleterious Effect of Cirrhosis on Outcomes After Motor Vehicle Crashes Using the Nationwide Inpatient Sample

OBJECTIVES:Alcohol abuse and minimal hepatic encephalopathy may predispose cirrhotics to a higher motor vehicle crash (MVC) rate. Cirrhotics have poor post-trauma outcomes on small-scale studies. The aim was to examine the effect of cirrhosis on mortality, charges, and length of stay (LOS) after MVCs using the Nationwide Inpatient Sample (NIS) 2004.METHODS:NIS 2004 was queried for cirrhotics with MVC (C-MVC), cirrhotics only, and MVC only for demographics, comorbidities, hospital characteristics, and the Injury Severity Score (ISS). C-MVC patients were compared with the other groups. Weighted uni/multivariate regression was performed for all MVCs (with/without cirrhosis). RESULTS:There were 560,080 discharges for cirrhosis only, 262,244 for MVC only, and 1,565 for C-MVC. C-MVC patients were significantly younger (49.8 yr vs 58.6 yr, P < 0.0005) and had less comorbidities than cirrhosis only, but had similar mortality (C-MVC 10.8% vs cirrhosis only 9.9%, P= 0.23). C-MVC patients (49.8 yr) were older than MVC only patients (43.7 yr, P < 0.0005). C-MVC patients also had significantly higher mortality (10.8%) compared with MVC only (3.1%, P < 0.0005) despite similar ISS. C-MVC patients had significantly greater LOS (9.6 days) and charges ($67,119) compared with both MVC only (6.2 days, $43,314) and cirrhosis only (7.4 days, $35,522). Cirrhosis (odds ratio [OR] 3.5, 95% confidence interval [CI] 2.5–5.5) and age >65 yr (OR 5.2, 95% CI 4.4–6.0) were most commonly associated with mortality. Male sex, high ISS, self-pay, teaching, and large and urban hospitals were also significantly associated with mortality. On multivariate regression, cirrhosis was associated with greater charges and LOS.CONCLUSION:Cirrhosis is associated with greater mortality, LOS, and charges after MVC despite controlling for injury severity, comorbidities, and age in NIS 2004.
Health-related quality-of-life assessment in patients with low back pain using SF-36 questionnaire.

OBJECTIVE For complete assessment of benefits of the surgical intervention, it is essential to provide evidence of the impact on patients in terms of health status and health-related quality of life. In the present study, the preoperative 36-item Short Form (SF-36) Health Survey scores were determined in patients before lumbar microdiscectomy due to better preoperative screening likewise in the control group--almost healthy population taken into account any habitual ailments experienced in an appropriate age. PATIENTS AND METHODS In the present study, we investigated a cohort of 100 patients with disc herniation causing low back pain and another hundred of the control subjects, matched by age and gender. The short form 36 general health questionnaire (SF-36) was applied. RESULTS Estimation of the SF-36 scores showed that (1) all of the domain values were considerably lower in the preoperative patient group than in the second one (P<0.01); (2) the bodily pain scores were closely correlated to the social function scores (R=0.7, P<0.01), whereas the physical function was less related to the bodily pain (R=0.6, P<0.01). The weakest correlation was observed between bodily pain and mental health and general health (R=0.4, P<0.01). CONCLUSION The present study showed that the generic instrument, SF-36 Health Survey, was optimized paraclinical method for patients predisposed to surgical treatment of the lumbar disc herniation disease likewise for normal population individuals, matched by age and sex, in the assessment of health-related quality of life.

Effects of Dantrolene on Extracellular Glutamate Concentration and Neuronal Death in the Rat Hippocampal CA1 Region Subjected to Transient Ischemia

Background Excessive extracellular glutamate produced by cerebral ischemia has been proposed to initiate the cascade toward neuronal cell death. Changes in extracellular glutamate concentration are closely linked to changes in intracellular calcium ion concentration. Dantrolene inhibits calcium release from intracellular calcium stores. In this study, the authors investigated the effects of dantrolene on extracellular glutamate accumulation and neuronal degeneration in a rat model of transient global forebrain ischemia. Methods Male Wistar rats weighing 230–290 g were anesthetized with halothane in nitrous oxide–oxygen and were subjected to 10 min of transient forebrain ischemia using a four-vessel occlusion technique. Fifteen minutes before ischemic injury, dantrolene sodium (5 mm), dimethyl sulfoxide as a vehicle for dantrolene, or artificial cerebrospinal fluid as a control was intracerebroventricularly administered (n = 8 in each group). In the hippocampal CA1 subfield, the extracellular glutamate concentration in vivo was measured during the periischemic period with a microdialysis biosensor, and the number of intact neurons was evaluated on day 7 after reperfusion. Results Both dantrolene and dimethyl sulfoxide significantly reduced the ischemia-induced increase in glutamate concentration to a similar extent, i.e., by 53 and 51%, respectively, compared with artificial cerebrospinal fluid (P < 0.01). The number of intact hippocampal CA1 neurons (mean ± SD; cells/mm) in dantrolene-treated rats (78 ± 21) was significantly higher than that in artificial cerebrospinal fluid– (35 ± 14;P < 0.001) and dimethyl sulfoxide–treated (56 ± 11;P < 0.05) animals. Dimethyl sulfoxide also significantly increased the number of preserved neurons in comparison with artificial cerebrospinal fluid (P < 0.05). Conclusions Intracerebroventricular dantrolene prevents delayed neuronal loss in the rat hippocampal CA1 region subjected to transient ischemia; however, this neuroprotection cannot be accounted for only by the reduced concentrations of extracellular glutamate during ischemia.
Biochemical characterization of air‐filled albumin microspheres

Heating and sonication of a solution of human serum albumin (HSA) yields air‐filled microspheres that can be used as a contrast agent in ultrasound examinations. The microspheres are stabilized by a thin‐layer of protein surrounding the air bubbles. As long as the microspheres were intact, the protein was insoluble in aqueous solutions. After disintegration of the microspheres, the protein could be solubilized in several solutions. The intermolecular interactions in the microsphere protein have been elucidated from its solubility properties. The microspheres were disintegrated by several detergents which also solubilized the protein. After pressure disintegration of the microspheres, the protein was solubilized immediately in urea and guanidinium chloride, and also in phosphate‐buffered saline after incubation overnight. These results indicate that the protein was mainly stabilized by non‐covalent forces. The solubilization in buffer was inhibited by a high salt concentration, suggesting that hydrophobic interactions were involved in stabilizing the microsphere structure. Analysis of the solubilized protein by gel filtration showed that the protein contained substantial amounts of soluble aggregates of HSA. Reduction of the disulphide bonds dissolved these aggregates into monomeric HSA, showing that intermolecular disulphide bonds were also involved in stabilization of the microspheres. The solubilized protein also contained less fatty acids than the soluble HSA used for the production of microspheres. These results show that the microsphere protein has the same characteristics as heat‐denatured HSA.
Mycoplasmas: A Distinct Cytoskeleton for Wall-Less Bacteria

The bacterial genus Mycoplasma includes a large number of highly genomically-reduced species which in nature are associated with hosts either commensally or pathogenically. Several Mycoplasma species, including Mycoplasma pneumoniae, feature a multifunctional polar structure, the terminal organelle. Essential for colonization of the host and for gliding motility, the terminal organelle is associated with an internal cytoskeleton crucial to its assembly and function. This cytoskeleton is structurally and compositionally novel as compared with the cytoskeletons of other organisms, including other bacteria, is also involved in the cell division process. In this review we discuss the cytoskeletal structures and protein components of the attachment organelle and how they might interact and contribute to its various functions.
Amyloid Precursor Protein and Presenilin Involvement in Cell Signaling

To date the most relevant role for the amyloid precursor protein (APP) and for the presenilins (PSs) on Alzheimer’s disease (AD) genesis is linked to the ‘amyloid hypothesis’, which considers an aberrant formation of amyloid-β peptides the cause of neurodegeneration. In this view, APP is merely a substrate, cleaved by the γ-secretase complex to form toxic amyloid peptides, PSs are key players in γ-secretase complex, and corollary or secondary events are Tau-linked pathology and gliosis. A second theory, complementary to the amyloid hypothesis, proposes that APP and PSs may modulate a yet unclear cell signal, the disruption of which may induce cell-cycle abnormalities, neuronal death, eventually amyloid formation and finally dementia. This hypothesis is supported by the presence of a complex network of proteins, with a clear relevance for signal transduction mechanisms, which interact with APP or PSs. In this scenario, the C-terminal domain of APP has a pivotal role due to the presence of the 682YENPTY687 motif that represents the docking site for multiple interacting proteins involved in cell signaling. In this review we discuss the significance of novel findings related to cell signaling events modulated by APP and PSs for AD development.
Validity and Reproducibility of a Food Frequency Questionnaire for Dietary Factors Related to Colorectal Cancer

Dietary factors play a major role in the development of colorectal cancer. This study evaluated the reproducibility and validity of a 109-food item Food Frequency Questionnaire (FFQ) to measure the consumption of foods and nutrients related to the development of colorectal cancer in a population aged ≥50 years in Flanders, Belgium. A semi-quantitative FFQ was administered two times in a period of two weeks to evaluate reproducibility (FFQ1 and FFQ2). The validity of the FFQ was assessed by comparing FFQ1 against the 3-day diary method (3 DD). A total of 162 respondents (mean age 57.5 years) provided data for the FFQ, of whom 156 also participated in the validity assessment. Mean differences in the intake of foods and nutrients between FFQ1 and FFQ2 were, overall, small and statistically insignificant. However, a higher estimation was observed by FFQ1 as compared to the 3-DD method for the majority of food groups and nutrient intake in the validity assessment. A systematic mean difference (g/day) was observed for eight food groups in the Bland–Altman agreement test; the largest was for fruit intake. Regarding the nutrients, a systematic mean difference was observed in calcium, fat, and vitamin D intake. Overall, the reproducibility of the FFQ was good, and its validity could be satisfactory for estimating absolute food and nutrient intakes and ranking individuals according to high and low intake categories.
Boeravinone B, A Novel Dual Inhibitor of NorA Bacterial Efflux Pump of Staphylococcus aureus and Human P-Glycoprotein, Reduces the Biofilm Formation and Intracellular Invasion of Bacteria

This study elucidated the role of boeravinone B, a NorA multidrug efflux pump inhibitor, in biofilm inhibition. The effects of boeravinone B plus ciprofloxacin, a NorA substrate, were evaluated in NorA-overexpressing, wild-type, and knocked-out Staphylococcus aureus (SA-1199B, SA-1199, and SA-K1758, respectively). The mechanism of action was confirmed using the ethidium bromide accumulation and efflux assay. The role of boeravinone B as a human P-glycoprotein (P-gp) inhibitor was examined in the LS-180 (colon cancer) cell line. Moreover, its role in the inhibition of biofilm formation and intracellular invasion of S. aureus in macrophages was studied. Boeravinone B reduced the minimum inhibitory concentration (MIC) of ciprofloxacin against S. aureus and its methicillin-resistant strains; the effect was stronger in SA-1199B. Furthermore, time–kill kinetics revealed that boeravinone B plus ciprofloxacin, at subinhibitory concentration (0.25 × MIC), is as equipotent as that at the MIC level. This combination also had a reduced mutation prevention concentration. Boeravinone B reduced the efflux of ethidium bromide and increased the accumulation, thus strengthening the role as a NorA inhibitor. Biofilm formation was reduced by four–eightfold of the minimal biofilm inhibitory concentration of ciprofloxacin, effectively preventing bacterial entry into macrophages. Boeravinone B effectively inhibited P-gp with half maximal inhibitory concentration (IC50) of 64.85 μM. The study concluded that boeravinone B not only inhibits the NorA-mediated efflux of fluoroquinolones but also considerably inhibits the biofilm formation of S. aureus. Its P-gp inhibition activity demonstrates its potential as a bioavailability and bioefficacy enhancer.
A qualitative analysis of the nutritional requirements of palliative care patients.

BACKGROUND The National Health Servive (NHS) Quality Improvement Scotland developed nutritional Clinical Standards to address the problem of malnutrition in hospitals. NHS palliative care units are obliged to incorporate these standards into nutritional aspects of care. The nutritional needs of this patient population are under-researched. The present study aimed to explore patients' views of nutrition, to begin to understand their concerns and to determine whether such standards meet the needs of patients in the palliative care setting. METHODS A qualitative study was conducted in 2009 in an NHS Palliative Care Unit. Six inpatients were involved in one-to-one interviews, which were audiotaped and transcribed verbatim. The transcripts were subject to qualitative data analysis in accordance with a previous framework. RESULTS A recurring theme that emerged was that of change and uncertainty. Four main areas subject to change were: disease state, symptoms, oral dietary intake and weight. Each change could exert control over, or be controlled by, the patient. When patients were eventually unable to exert control, they accepted the change, either willingly or enforced, thereby unintentionally setting their own targets. CONCLUSIONS The present study enables a deeper understanding of the concerns that palliative care patients have regarding their oral dietary intake and weight. Their 'malnutrition' not only refers to physical malnutrition alone, but also incorporates psychological and social 'malnutrition'. When applying standards or protocols regarding nutritional care, these wider issues must be taken into account to meet patients' nutritional needs.
Gewerkschaften und Arbeitsmärkte in Entwicklungsländern

Ursachen für diese Schwächung sind die wirtschaftliche Globalisierung, der technologische Wandel und das Wachstum des Dienstleistungssektors zu Lasten der Industrie, die in eine zunehmende Prekarisierung von Arbeitsverhältnissen mündet. Diese Erkenntnisse wurden hauptsächlich aus der Analyse von Arbeitsmärkten in Industriestaaten gewonnen und lassen sich nicht ohne weiteres auf weniger entwickelte Volkswirtschaften übertragen.
