Weed management under different patterns of sunflower-soybean intercropping.

Two field experiments were conducted at the Experimental Farm of the National Research Centre at Shalakan, Kalubia Governorate, Egypt during the 2005 and 2006 seasons to study the effect of three weed management {hand hoeing twice, butralin+prometryn and unweeded check} as well as six intercropping patterns {two pure stand crops, besides intercropping sunflower: soybean {sun: soy} alternating ridges 1:1, 1:2, 2:1 as well as side: side}. Results showed that the lowest light intensity was recorded with sole soybean. Hoeing achieved the lowest dry weights of the grassy, broad-leaved and total weeds, but statistically leveled with those of butralin+prometryn in grassy and broad-leaved weeds. The lowest dry weight of grasses was recorded with 1:1 and 1:2 intercropping patterns. Hoeing was the best treatment for promoting sunflower and soybean seed yields/fed. Among the intercropping systems, the pattern of side: side appeared the highest significant sunflower seed yield than the rest of other intercropping ones and could recover maximum of its sole sunflower yield (81.3 %). The highest LER values, i.e. 1.376 and 1.198 recorded when sunflower and soybean intercropped in side: side and 1:2, respectively. The Aggressivity values indicated that sunflower component was the dominated, while soybean was the dominant one.
Screening for early lung cancer with low-dose spiral CT: prevalence in 817 asymptomatic smokers.

PURPOSE To present prevalence screening data from a nonrandomized screening trial by using low-dose computed tomography (CT) and a simple algorithm based on the size and attenuation of detected nodules to guide diagnostic work-up. MATERIALS AND METHODS Eight hundred seventeen asymptomatic volunteers (age range, 40-78 years; median age, 53 years; median tobacco consumption, 45 pack-years) underwent spiral low-dose CT of the chest without contrast material enhancement. We regarded all noncalcified pulmonary nodules greater than 10 mm in diameter as potentially malignant and recommended histologic examination or follow-up after 3, 6, 12, and 24 months to exclude growth. For noncalcified pulmonary nodules of 10 mm or smaller, repeat low-dose CT was recommended to exclude growth. RESULTS In 43% (350 of 817) of individuals, 858 noncalcified pulmonary nodules were found. Thirty-two nodules in 29 subjects were larger than 10 mm. Biopsy of 15 lesions revealed lung cancer in 12 lesions in 11 subjects (prevalence for all ages, 1.3% [11 of 817 subjects]; >50 years of age, 2.1% [11 of 519 subjects]; >60 years of age, 3.9% [eight of 206 subjects]), with a high proportion of early tumor stages (seven tumors, stage I; two, stage II; and three, stage III); three lesions were benign. In 17 nodules larger than 10 mm, follow-up with low-dose CT for a minimum of 24 months did not demonstrate growth. CONCLUSION Lung cancer screening with low-dose CT demonstrated a prevalence of asymptomatic cancers in 1.3% of a smoking population, including a high proportion of early tumor stages and a 20% (three of 15) rate of invasive procedures for benign lesions.
Crecimiento: una visión desde la Antropología Física

Growth can be defined as the increment of total body size, considered as a whole or globally, as well as the size/dimension attained for specific parts/segments of the body. Changes in size can be accompanied by modifications in shape and composition. Growth studies have a large tradition in Physical Anthropology discipline, because of their variation in function of the different biological and socio-environmental factors, and because of the complex interactions established among them. The use of growth data for the description of Rebato
Receptor Protein-tyrosine Phosphatase RPTPμ Binds to and Dephosphorylates the Catenin p120 ctn *

RPTPμ is a prototypic receptor-like protein-tyrosine phosphatase (RPTP) that mediates homotypic cell-cell interactions. Intracellularly, RPTPμ consists of a relatively large juxtamembrane region and two phosphatase domains, but little is still known about its substrate(s). Here we show that RPTPμ associates with the catenin p120 ctn , a tyrosine kinase substrate and an interacting partner of cadherins. No interaction is detectable between RPTPμ and β-catenin. Furthermore, we show that tyrosine-phosphorylated p120 ctn is dephosphorylated by RPTPμ both in vitro and in intact cells. Complex formation between RPTPμ and p120 ctn does not require tyrosine phosphorylation of p120 ctn . Mutational analysis reveals that both the juxtamembrane region and the second phosphatase domain of RPTPμ are involved in p120 ctn binding. The RPTPμ-interacting domain of p120 ctn maps to its unique N terminus, a region distinct from the cadherin-interacting domain. A mutant form of p120 ctn that fails to bind cadherins can still associate with RPTPμ. Our findings indicate that RPTPμ interacts with p120 ctn independently of cadherins, and they suggest that this interaction may serve to control the tyrosine phosphorylation state of p120 ctn at sites of cell-cell contact.
Influence of salts on electrostatic interactions between poliovirus and membrane filters

Neither solutions of salts nor solutions of detergents or of an alcohol at pH 4 are capable of eluting poliovirus adsorbed to membrane filters. However, solutions containing both a salt, such as magnesium chloride or sodium chloride, and a detergent or alcohol at pH 4 were capable of eluting adsorbed virus. The ability of ions to promote elution of virus at low pH in the presence of detergent or alcohol was dependent on the size of the ions and the ionic strength of the medium. These results suggest that both electrostatic and hydrophobic interactions are important in maintaining virus adsorption to membrane filters. Hydrophobic interactions can be disrupted by detergents or alcohols. It appears that electrostatic interactions can be disrupted by raising the pH of a solution or by adding certain salts. Disruption of either electrostatic or hydrophobic interactions alone does not permit efficient elution of the adsorbed virus at low pHs. However, when both interactions are disrupted, most of the poliovirus adsorbed to membrane filters is eluted, even at pH 4.
On the Complementary Value of Accurate Demand Information and Production and Supplier Flexibility

We study the value of information, production flexibility, and supplier flexibility for a good for which an initial and a subsequent order may be placed. We consider a Bayesian model of demand in which the unknown mean demand rate is assumed to have a prior, which is a mixture of two normal distributions corresponding to the demand forecast for an innovative (fashion) good. We develop three models of production flexibility: a static model requiring initial placement of both orders, a partially dynamic model requiring a fixing of the time that the second order will be made, and a fully dynamic model with no restrictions on ordering. Supplier flexibility is modeled through supply lead times. We observe that the magnitude of the savings from the static to the fully flexible model, corresponding to the sum of the values of information and production flexibility, reflects all sources of variability: differences between demand means of the prior mixture, variability within each prior, and variability about the observed mean. We observe that as the difference between high and low demand cases increases, the value of information increases, though for long lead times, production flexibility is required to take advantage of the updated information. Further, we observe that the greater the uncertainty within each prior distribution, the greater the value of information relative to the value of production flexibility, particularly for long lead times. However, the greater the uncertainty around the mean demand, which is the uncertainty that cannot be resolved through observation, the lower the value of information. Finally, we observe that the value of supply flexibility grows initially in a concave then convex manner as a function of the supply lead times.
Monitoring human wrist rotation in three degrees of freedom

This paper presents a rotation tracking system using a tri-axis MEMS accelerometer and a tri-axis magnetometer sensor that is placed on the human hand. This system recognizes the human wrist's rotation in the pronation-supination, extension-flexion and ulnar-radial movements. The proposed system also is able to measure the degrees of the rotations.
Protective effects of aspirin and vitamin E (alpha-tocopherol) against copper- and cadmium-induced toxicity.

A 24-h exposure to copper (400 microM, 600 microM) or cadmium (5 microM, 10 microM) significantly reduces the viability of COS-7 cells. A 2-h preincubation with vitamin E does not protect COS-7 cells from copper-induced toxicity, but does protect against cadmium-induced toxicity. Preincubation with aspirin protects cells from both copper- and cadmium-induced toxicity. A combination of aspirin and vitamin E (10 microM and 25 microM, respectively) increases cell viability in copper-exposed cells in a clearly additive manner, while in cadmium-exposed cells the effects are slightly additive. These results indicate that aspirin and vitamin E can protect cells from metal-induced toxicity. Differences in the protective effects of aspirin and vitamin E on copper versus cadmium-induced toxicity may be due to alternative mechanisms of metal toxicity or antioxidant activity.
Belastungsorientierte Just-in-Time Variantenfließfertigung

Gegenstand der vorliegenden Arbeit sind zwei praktisch und theoretisch bedeutsame Probleme, die bei just-in-time orientierter Variantenfliesfertigung auftreten. Ein Problem besteht darin, den Teilebedarf in der Endmontage so konstant wie moglich zu halten ("Level Scheduling Problem"). Das zweite Problem versucht, die Belastung der Arbeitsstationen moglichst konstant zu halten ("Car Sequencing Problem"). In der vorliegenden Arbeit werden beide Probleme als kombiniertes ganzzahliges Optimierungsproblem formuliert. Die LP-Relaxation des Modells wird mit Hilfe der Methode der Spaltengenerierung gelost. In einer experimentellen Studie zeigt sich, das mit dieser Technik auch grosere Instanzen naherungsweise optimal gelost werden konnen.
A V-Band MMIC SPDT passive HEMT switch using impedance transformation networks

A V-Band MMIC single pole double throw (SPDT) switch using GaAs PHEMT process is designed, fabricated and tested. In contrast to the conventional resonant-type switch design method, this passive FET switch circuit utilizes impedance transformation to compensate the drain-source capacitance effect for the off-state in millimeter-wave frequency range. This SPDT switch has a measured isolation better than 30 dB for the off-state and 4 dB insertion loss for the on-state from 53 GHz to 61 GHz. The isolation performance of this design approach outmatches previously published FET switches in this frequency range.
Intensive speech therapy for cleft palate children.

Forty six children with deviant articulation secondary to cleft palate or other velo-pharyngeal disorders took part in a controlled trial, to gauge the efficacy of intensive speech therapy. Subjects were randomly allocated either to attend a six-week intensive course of speech therapy, or to continue with their conventional weekly therapy. Results indicate a significant improvement in articulation for those children receiving intensive help immediately post-course as compared with a very slight improvement seen in the speech of the control group. This improvement achieved by children on the course was maintained throughout the two-year follow-up period and, although the articulation of the control group continued to improve, at the end of the two year follow-up period the children on the course had better articulation scores
Reductions of Rubisco Activase by Antisense RNA in the C4 Plant Flaveria bidentis Reduces Rubisco Carbamylation and Leaf Photosynthesis

To function, the catalytic sites of Rubisco (EC 4.1.1.39) need to be activated by the reversible carbamylation of a lysine residue within the sites followed by rapid binding of magnesium. The activation of Rubisco in vivo requires the presence of the regulatory protein Rubisco activase. This enzyme is thought to aid the release of sugar phosphate inhibitors from Rubisco's catalytic sites, thereby influencing carbamylation. In C3 species, Rubisco operates in a low CO2 environment, which is suboptimal for both catalysis and carbamylation. In C4 plants, Rubisco is located in the bundle sheath cells and operates in a high CO2 atmosphere close to saturation. To explore the role of Rubisco activase in C4 photosynthesis, activase levels were reduced in Flaveria bidentis, a C4 dicot, by transformation with an antisense gene directed against the mRNA for Rubisco activase. Four primary transformants with very low activase levels were recovered. These plants and several of their segregating T1 progeny required high CO2 (>1 kPa) for growth. They had very low CO2 assimilation rates at high light and ambient CO2, and only 10% to 15% of Rubisco sites were carbamylated at both ambient and very high CO2. The amount of Rubisco was similar to that of wild-type plants. Experiments with the T1 progeny of these four primary transformants showed that CO2 assimilation rate and Rubisco carbamylation were severely reduced in plants with less than 30% of wild-type levels of activase. We conclude that activase activity is essential for the operation of the C4 photosynthetic pathway.

Induced oncogenesis in developing frog kidney cells.

Summary The transmission of frog renal tumors (Lucke) and subsequent induction of primary tumors by implantation or inoculation of tumor cell components into embryos and larvae of Rana pipiens has been studied. Tumor cells were fractionated by centrifugation and filtration into oncogenically active subcellular components. The fractions were differentiated according to particle size, as mitochondrial, light mitochondrial, and microsomal fractions. Each of these contained aggregated or free viral particles when tumors with intranuclear inclusion bodies were used. Injection of the mitochondrial and microsomal fractions into embryos from the blastula through the hatching stage induced renal carcinomas which appeared during or after metamorphosis. Both the pronephric and mesonephric kidneys developed tumors. The filtrate fraction (0.45 µ) of the tumor extract was less active but also caused renal tumor induction. The resultant renal carcinomas were identical with spontaneous, actively growing, primary adenocarcinomas. Both operational controls and fractions of normal kidney failed to produce tumors of any kind. Implants of primary tumors into embryos “took” but were eventually rejected and failed to cause local or primary tumor growths. Injection of living dissociated tumor cells into embryos or larvae likewise failed to establish local growths or induced primary renal tumors in the young adults.
Human-robots implicit communication based on dialogue between robots using automatic generation of funny scenarios from web

Numerous studies have examined communication robots that communicate with people, but it is difficult for robots to communicate with people smoothly. We call the communication style based on dialogue between robots as “human-robot implicit communication”. As described herein, we propose a Manzai-robots for which the interaction style is human-robot implicit communication based on an automatically generated scenario from web news. Our generated Manzai scenario consists of snappy patter and a misunderstanding of dialogue based on the four kinds of gap of structure of funny points. Our purpose is that people feel familiarity from smoothly human-robot communication using dialogue between robots based on a Manzai scenario. We conducted experiment of three kinds to assess (1) the effectiveness of automatic creation of Manzai scenario for the robots, (2) the effectiveness of the Manzai-robots as a media, and (3) the effectiveness of types of familiarity for Manzai-robots. Based on their results, we measured the familiarity and smooth communication of our Manzai-robots.
Cytomegalovirus Central Nervous System Compartmentalization in a Patient Presenting with AIDS

Cytomegalovirus (CMV) central nervous system involvement is uncommon and hardly diagnosed because it can mimic many different conditions. We here present a case of an HIV-positive patient with neurological signs and symptoms (headache, asthenia, confusion, hallucinations, ataxia) with concurrent opportunistic diseases (neurotoxoplasmosis, disseminated Kaposi's sarcoma, disseminated CMV infection). CMV CNS involvement was not initially considered given the observed multiple comorbidities: antiviral treatment duration was probably not adequate given the end-organ disease. Concomitantly, plasma CMV DNA was undetectable while cerebrospinal fluid viral load was 31,340 copies/ml. Ganciclovir treatment followed by oral valganciclovir maintenance was associated with the slow disappearance of symptoms, the improvement of MRI images and the persistent undetectability of CMV DNA. The case here reported highlights the challenges of diagnosing CMV encephalitis in HIV-positive patients (with several cerebral comorbidities), the incomplete knowledge of the appropriate treatment for such a disease and the possibility of CMV replication in the cerebrospinal fluid despite undetectable plasma CMV DNA.
Ambulatory arterial stiffness index: rationale and methodology

ObjectivesIncreased arterial stiffness is associated with the development of cardiovascular disease and may even predict its development at an early stage. Increased pulse pressure is seen as a marker of increased arterial stiffness and can be readily measured by ambulatory blood pressure monitoring. We propose another surrogate measure of arterial stiffness derived from ambulatory blood pressure monitoring that may predict cardiovascular mortality over and above pulse pressure, namely, the dynamic relationship between diastolic and systolic blood pressure over 24 h – the ambulatory arterial stiffness index. MethodsUsing all blood pressure readings over the 24-h period from 11 291 (5965 women; mean age 54.6 years) patients referred for ambulatory blood pressure monitoring to a blood pressure clinic, diastolic blood pressure was plotted against systolic blood pressure, and the regression slope was calculated; ambulatory arterial stiffness index was defined as one minus this regression slope. ResultsBoth ambulatory arterial stiffness index and pulse pressure were higher in women (0.42 vs. 0.40 and 57.0 vs. 55.3 mmHg, respectively). For the entire group, the correlation between ambulatory arterial stiffness index and pulse pressure was 0.5. ConclusionsAmbulatory arterial stiffness index is a new measure that is readily available from ambulatory blood pressure monitoring and may provide added prognostic information for cardiovascular outcome.

The effect of additional core stability exercises on improving dynamic sitting balance and trunk control for subacute stroke patients: a randomized controlled trial

Objective: To examine the effect of core stability exercises on trunk control, dynamic sitting and standing balance, gait, and activities of daily living in subacute stroke patients. Design: A randomized controlled trial. Setting: Inpatient rehabilitation hospital in two centres. Subjects: Eighty patients (mean of 23.25 (±16.7) days post-stroke) were randomly assigned to an experimental group and a control group. Interventions: Both groups underwent conventional therapy for five days/week for five weeks and the experimental group performed core stability exercises for 15 min/day. The patients were assessed before and after intervention. Main measures: The Trunk Impairment Scale (Spanish-Version) and Function in Sitting Test were used to measure the primary outcome of dynamic sitting balance. Secondary outcome measures were standing balance and gait as evaluated via Berg Balance Scale, Tinetti Test, Brunel Balance Assessment, Postural Assessment Scale for Stroke (Spanish-Version), and activities of daily living using Barthel Index. Results: The experimental group showed statistically significant differences for all of the total scale scores (P<0.05), except for the sitting section of the Brunel Balance Assessment. The mean (SD) difference between groups in Trunk Impairment Scale total score was 3.40 (±4.12) points, and its subscale dynamic sitting balance was 2.28 (±3.29). The Berg Balance Scale was 14.54 (±18.19) points, and the Barthel Index was 13.17 (±25.27) points. Collectively, these results were in favour of the experimental group. Conclusions: Core stability exercises in addition to conventional therapy improves trunk control, dynamic sitting balance, standing balance, gait and activities of daily living in subacute post-stroke patients.
