An adaptive plan-based approach to integrating semantic streams with remote RDF data

To satisfy a user’s complex requirements, Resource Description Framework (RDF) Stream Processing (RSP) systems envision the fusion of remote RDF data with semantic streams, using common data models to query semantic streams continuously. While streaming data are changing at a high rate and are pushed into RSP systems, the remote RDF data are retrieved from different remote sources. With the growth of SPARQL endpoints that provide access to remote RDF data, RSP systems can easily integrate the remote data with streams. Such integration provides new opportunities for mixing static (or quasi-static) data with streams on a large scale. However, the current RSP systems do not offer any optimisation for the integration. In this article, we present an adaptive plan-based approach to efficiently integrate sematic streams with the static data from a remote source. We create a query execution plan based on temporal constraints among constituent services for the timely acquisition of remote data. To predict the change of remote sources in real time, we propose an adaptive process of detecting a source update, forecasting the update in the future, deciding a new plan to obtain remote data and reacting to a new plan. We extend a SPARQL query with operators for describing the multiple strategies of the proposed adaptive process. Experimental results show that our approach is more efficient than the conventional RSP systems in distributed settings.
PLA2G6 mutations in PARK14‐linked young‐onset parkinsonism and sporadic Parkinson's disease

Mutations of PLA2G6 gene have been lately proposed to be the causative gene for PARK14 in patients with autosomal recessive young‐onset parkinsonism (YOPD). The role of PLA2G6 mutations as a risk factor for Parkinson's disease is not clear. To study the PLA2G6 mutations in PARK14‐linked patients and its association with the onset of sporadic Parkinson's disease (sPD), sequencing and gene dosage analyses were carried out in 25 patients (onset age ≦30 years) then the identified variants were assessed in 956 sporadic PD (sPD) patients and 802 age‐matched healthy controls. Four genetic variants were identified; one patient had homozygous c.991G > T (p.Asp331Tyr) mutation, two had compound heterozygous c.991G > T/c.1077G > A (p.Met358IlefsX) mutation, one had single c.1976A > G (p.Asn659Ser) mutation, and one patient had an exon 1 hetero‐deletion. The c.1077G > A mutation resulted in a 4‐bp deletion in leukocyte mRNA by activating a cryptic splice site in exon 7. Only p.Asp331Tyr was identified in four sPD patients and four controls. The onset age for PLA2G6 mutation carriers was younger than that for sPD (29.86 ± 8.59 vs. 56.84 ± 11.33 years, P = 0.0002). The analysis of previously reported PARK14 patients revealed that those who carried a truncated mutation tended to have a complicated phenotype and atrophies of cortex and cerebellum. In conclusion, PLA2G6 mutation was the second common genetic cause after PRKN mutation in our YOPD patients and might be a risk factor for early‐onset PD in Han Chinese. Additionally, mutation data should be interpreted carefully because even a synonymous mutation could cause abnormal mRNA splicing. © 2011 Wiley Periodicals, Inc.
A Polarization-Reconfigurable Dipole Antenna Using Polarization Rotation AMC Structure

A novel polarization-reconfigurable mechanism based on a polarization-rotation artificial magnetic conductor (PRAMC) structure is proposed. A new polarizationreconfigurable antenna is designed by combining a PRAMC-based multipolarized dipole antenna with a RFIC switch-based network, in which three polarization states of right-handed, left-handed circular polarization (RHCP, LHCP) and +45° linear polarization (LP) can be realized by controlling the dc bias of the switches accordingly. The multipolarization antenna is well designed for offering three polarization states. A large 3-dB axial ratio (AR) bandwidth of 15.5%, a wide 3-dB AR beamwidth for CP states and a large cross-polarization isolation of more than 50 dB for LP state together with a broad impedance bandwidth of 20.5% are obtained. A switch network is used to generate three feeding modes, and the performance of the RF-integrated circuit (RFIC) switches is experimentally verified. A prototype of the proposed polarization-reconfigurable antenna is fabricated and tested. Good agreements between the measured and simulated results are observed, which indicates good performances of the proposed antenna.
Inhibition of tumor necrosis factor activity minimizes target organ damage in experimental autoimmune uveoretinitis despite quantitatively normal activated T cell traffic to the retina

Recent studies demonstrated that administration of a p55‐tumor necrosis factor (TNF) receptor IgG‐fusion protein (TNFR‐IgG) prevented the clinical onset of experimental autoimmune encephalomyelitis but did not alter the number or tissue distribution of autoantigen‐specific CD4+ effector T cells which trafficked into the central nervous system. To determine whether specific target tissues of autoimmune damage remain intact after TNFR‐IgG treatment despite the presence of inflammatory cells within the tissues, we examined rats with experimental autoimmune uveoretinitis (EAU), as in this model, the main target of autoreactive CD4+ T cells, the retinal rod outer segments (ROS), can be examined readily by light microscopy. As judged by direct ophthalmoscopy, the onset of inflammation in the anterior chamber of the eye in EAU following administration of TNFR‐IgG was delayed by 6 days compared to untreated controls, but the magnitude of the response was only slightly less than controls. Histological examination of the retinae and direct assessment of retinal inflammation revealed a disproportionate sparing of ROS in the TNFR‐IgG‐treated animals despite a level of retinal inflammation not substantially less than controls in which ROS damage was marked. Analysis of retinal leukocytes by immunofluo‐rescence microscopy and flow cytometry indicated that approximately equal numbers of CD4+ αβTCR+ lymphocytes were present in treated and control retinae, more than 30% of CD4+ cells in both experimental groups expressed the CD25 or MRC OX40 activation markers and most cells, which would include the CD4+ T lymphocytes, were activated as evidenced by MHC class II expression. Fewer activated macrophages and granulocytes were present in the treated retinae, possibly reflecting the lower level of tissue damage and subsequent accumulation of these inflammatory cells. The results demonstrate directly that a tissue specifically targeted for autoimmune destruction can be protected despite the influx of fully activated CD4+ T cells.
Body size‐associated survival and dispersal rates of Aedes aegypti in Rio de Janeiro

Abstract The daily survival rate of Aedes aegypti (L) (Diptera: Culicidae) is one of the most important parameters in mathematical models of dengue transmission. In this report, we evaluate the effect of adult body size on the survival and dispersal rates of male and female Ae. aegypti, the primary dengue vector in Brazil. Independent of larval diet (i.e. size), the daily survival rate of females recaptured in the field was greater than that of males (smaller: t = 5.617; d.f. = 15; P < 0.05; larger: t = 4.241; d.f. = 16; P < 0.05). Larger males lived longer than smaller males (t = 2.2893; d.f. = 7; P < 0.05), but no size effect was observed for females (t =– 0.086; d.f. = 19; P= 0.932). The daily survival rate of smaller females was similar to that of larger females (0.712 and 0.730, respectively, as calculated by an exponential model, and 0.743 and 0.779, respectively, calculated by a non‐linear model), and they dispersed further than larger females (mean distances travelled were 78.8 m and 40.9 m, respectively; t =− 10.22; d.f. = 323; P < 0.05). Adult body size did not influence male dispersal distances (t = 0.904; d.f. = 206; P= 0.367). Given our evidence that smaller females appear to have similar lifespans and evidence from other studies that they bite more frequently during a single gonotrophic cycle than larger females, our results suggest that smaller females have a higher vectorial capacity.
Improving estimations of phosphorus bioavailability for lactating dairy cows

Bioavailability of phosphorus (P) in feedstuffs has recently been reported to be unreliable. A recent survey of dairy nutritionists indicates a lack of confidence in the current coefficients for P availability which leads to overfeeding P on dairy farms (unpublished data). Quantification of total P and P-containing compounds in a variety of feedstuffs may help improve estimations of availability. One-hundred and seventy feed samples were gathered from two reputable commercial laboratories including forages, concentrates, and by-products. Each sample was classified by region fed. Samples were analyzed for total P, inorganic P (Pi), and phytate (Pp). The data was analyzed using the MIXED procedure of SAS to determine the effect of feed class and geographic region. Total P was greater (P < 0.10) in concentrates and byproducts as compared to forages. Concentrates had the lowest (P < 0.10) concentration of Pi, followed by by-products and then forages. Two fractions of P analyzed (Pi and Pp) accounted for 71.2% of total P in forages and 81.8 and 81.9% in concentrates and by-products, respectively. Very few regional differences were present. Data characterizing P forms in feedstuffs in addition to total P may lead to better estimations of P bioavailability and more accurate feeding recommendations in dairy cows.
Delayed clamping of the umbilical cord after delivery and implications for public cord blood banking

Public banking of umbilical cord blood units (CBUs) containing higher numbers of cells ensures timely engraftment after transplantation for increasing numbers of patients. Delayed clamping of the umbilical cord after birth may benefit some infants by preventing iron deficiency. Implications of delayed cord clamping for public cord blood banking remains unclear.

Variation in the host ABO blood group may be associated with susceptibility to hepatitis C virus infection

SUMMARY This study aimed to determine the relationship between hepatitis C virus (HCV) infection and ABO/Rhesus blood groups, age and sex. A total of 20 000 patients who came to donate blood in the blood bank of GSVM Medical College, Kanpur were enrolled in the study. Demographic data recorded for each patient included age, sex and blood group. Blood samples were tested for anti-HCV antibodies and ABO/Rhesus blood group antigen typing was performed. The overall positive rate of anti-HCV was 0·34%. We found that seropositivity for HCV increased with age. Anti-HCV antibodies were detected in 1/765 women (0·13%), compared to 67/19 235 men (0·35%). Seroprevalence of HCV was found to be higher in blood group O individuals (0·42%) and lowest in blood group AB individuals (0·04%). The results of this study demonstrate that that HCV infection may not be related to age and sex but the possible association of blood group antigens with HCV infection cannot be ruled out.
A Darwinian Legacy to Understanding Human Infancy

Abstract: Darwin's influence on the study of emotional responding has largely centered on the study of the production of facial movement patterns. In this paper, we present evidence on the importance of considering facial and vocal patterns as signals that powerfully regulate behavior in infancy and early childhood. We review a series of studies showing that facial expressions and vocal expressions alone can regulate the behavior of infants and, in the case of vocal expressions, do so at ages earlier than most researchers have acknowledged. We also review studies on the enduring effects of social signals, documenting that even 8.5‐month‐olds show minimal retention of the effects of social signals, some 10‐month‐olds can retain the effects of social signals for 25 minutes, and 14‐month‐old can do so for a period of one hour after only two trials of signal exposure. Social signals not only regulate behavior, they also are part and parcel of an important and relatively unstudied phenomenon called affect sharing, which is evident by 11.5 months of age. Finally, we speculate on the constitutive role of social signals, especially those linked to what Ekman has called “basic emotions” in the generation of new emotions, such as pride, shame, and guilt.

Pulsed-Field Gel Electrophoresis of Human Group B Streptococci Isolated in Brazil

Abstract The present study addresses epidemiological aspects of Brazilian human group B streptococci (GBS). GBS (103 isolates) were serotyped with specific rabbit anticapsular antibodies by double diffusion in agarose gels. They represented 3 serotypes: 26 II, 41 III, and 36 V. Thereafter, the strains were characterized by pulsed-field gel electrophoresis (PFGE) of DNA treated with SmaI. DNA restriction band sizes were compared and displayed 54 PFGE profiles that were arranged into 18 patterns. Of the predominant patterns detected for the 41 type III isolates 4 were observed in 15 strains from individuals with infections whereas only 3 were identified in 22 streptococci from healthy carriers. Such differences did not separate types II and V streptococci from carriers and patients. The PFGE method is a sensitive, precise, and powerful tool for discriminating streptococcal strains for epidemiological purposes.
MRI Contrast Enhancement of Necrosis by MP-2269 and Gadophrin-2 in a Rat Model of Liver Infarction

Ni Y, Adzamli K, Miao Y, et al. MRI contrast enhancement of necrosis by MP-2269 and gadophrin-2 in a rat model of liver infarction. Invest Radiol 2001;36:97–103. rationale and objectives. The mechanisms of action leading to specific localization of necrosis-avid contrast agents (NACAs) such as gadophrin-2 are not well defined. It has been suggested recently that agents with a high degree of serum albumin binding may also serve as NACAs by virtue of nonspecific hydrophobic interactions. The present MRI-histomorphology correlation study was conducted to verify the likelihood of the proposed albumin-binding mechanism by comparing an albumin-binding blood pool agent, MP-2269, with gadophrin-2 in a rat model of reperfused liver infarction. methods.Reperfused infarction in the right liver lobe was surgically induced in six rats. Serial T1-weighted MRI was performed before and after intravenous injection of MP-2269 at 0.05 mmol/kg and repeated in the same rats 24 hours later after intravenous injection of gadophrin-2 at the same dosage (0.05 mmol/kg). The MR images were matched with corresponding histomorphological findings. The signal intensity and contrast ratio of infarcted and normal hepatic lobes were quantified and compared between the two agents during the postcontrast course. results.Before contrast, the infarcted lobe was indiscernible from normal liver on T1-weighted MRI. Shortly after injection of both MP-2269 and gadophrin-2, a negative contrast occurred between infarcted and normal liver because of a strong liver signal intensity enhancement and an inferior uptake in the necrotic liver. On delayed phase (>60 minutes), a necrosis-specific contrast enhancement (contrast ratio 1.6) developed with gadophrin-2 but not with MP-2269. The MR images matched well with corresponding histomorphological findings. conclusions.Although both MP-2269 and gadophrin-2 feature an albumin-binding capacity, only gadophrin-2 displayed a persistent necrosis-specific contrast enhancement in the rat model of reperfused liver infarction. Therefore, the role of albumin binding in the mechanisms of NACAs should be reevaluated.
Plantar dermatoglyphic features of the Urhobos of southern Nigeria.

OBJECTIVE To establish the dermatoglyphic features of the Urhobos of southern Nigeria. DESIGN Cross sectional study of randomly selected Urhobo subjects. SETTING Department of Anatomy, College of Health Sciences, University of Port Harcourt, Port Harcourt, southern Nigeria. MAIN OUTCOME Plantar and digital pattern types were determined and Dankmeijer's (DI) and pattern intensity (PII) indices were calculated. RESULTS Males showed greater pattern types than females except in loops and whorls of the digits, where females showed greater numbers than males. The pattern intensity index was higher in females than in males. What appears characteristic to this group however, was the presence of few whorl distribution in the small toe in female subjects which was absent in male subjects. CONCLUSION This study thus provide normal dermatoglyphic features for the Urhobos of Southern Nigeria and also highlighted possible distinguishing dermtoglyphic difference between the Ibos and Urhobos of Southern Nigeria.
The Categorized and Invisible: The Effects of the ‘Border’ on Women Migrant Transit Flows in Mexico

In an increasingly globalized world, border control is continuously changing. Nation-states grapple with ‘migration management’ and maintain secure borders against ‘illegal’ flows. In Mexico, borders are elusive; internal and external security is blurred, and policies create legal categories of people whether it is a ‘trusted’ tourist or an ‘unauthorized’ migrant. For the ‘unauthorized’ Central American woman migrant trying to achieve safe passage to the United States (U.S.), the ‘border’ is no longer only a physical line to be crossed but a category placed on an individual body, which exists throughout her migration journey producing vulnerability as soon as the Mexico–Guatemala boundary is crossed. Based on policy analysis and fieldwork, this article argues that rather than protecting ‘unauthorized’ migrants, which the Mexican government narrative claims to do, border policies imposed by the state legally categorize female bodies in clandestine terms and construct violent relationships. This embodied illegality creates forced invisibility, further marginalizing women with respect to finding work, and experiences of sexual violence and abuses by migration actors. The analysis focuses on three areas: the changing definition of ‘borders’; the effects of categorization and multiple vulnerabilities on Central American women; and the dangers caused by forced invisibility.
Adolescent drug use: findings of national and local surveys.

Adolescent drug use increased until about 1981, but since then it has steadily declined. Current data show some drug use in the 4th and 5th grades and considerable increases from the 6th to the 9th grades. For drugs such as marijuana, cocaine, and stimulants, lifetime prevalence continues to increase through high school; for drugs such as inhalants and heroin, lifetime prevalence may decline for Grades 10, 11, and 12, suggesting that students who use these drugs early may drop out. Drug use of rural youth is similar to that of other youth. Barrio, ghetto, and Native-American reservation youth may have high rates of use, but use of Black and Hispanic seniors may be equivalent to or less than that of White seniors. National data and broadly defined ethnic data, however, may cover up important subgroup differences. For example, Western Mexican-American girls have lower use than Western Spanish-American girls, possibly because of the greater influence of "marianisma. " Different locations may also have very different patterns of adolescent drug use, calling for different types of local intervention.
Dental treatment improves self-rated oral health in homeless veterans--a brief communication.

OBJECTIVE The aim of this study was to assess homeless veterans' perception of their oral health and the impact that oral disease and treatment have on self-assessed quality of life. METHODS Outcomes included measures of general and oral-specific quality of life and functional status. Single-item self-report of oral health and the General Oral Health Assessment Index were assessed at baseline and after treatment. RESULTS One hundred and twelve veterans completed the baseline questionnaire, and 48 completed the follow-up. Veterans who were eligible for ongoing dental care had improved General Oral Health Assessment scores, while patients who received only emergency dental care saw a decreased score (2.46 versus -2.12). General Oral Health Assessment improvement was significantly related to fewer teeth at baseline (18 versus 23), a lower baseline General Oral Health Assessment (23.6 versus 28.1), having a denture visit (22 versus 35 percent), and improvement in self-reported oral health (25 versus 42 percent). CONCLUSION There was significant improvement in homeless veterans'perceived oral health after receiving dental care.
