Intensive blood-pressure control in hypertensive chronic kidney disease.

BACKGROUND In observational studies, the relationship between blood pressure and end-stage renal disease (ESRD) is direct and progressive. The burden of hypertension-related chronic kidney disease and ESRD is especially high among black patients. Yet few trials have tested whether intensive blood-pressure control retards the progression of chronic kidney disease among black patients. METHODS We randomly assigned 1094 black patients with hypertensive chronic kidney disease to receive either intensive or standard blood-pressure control. After completing the trial phase, patients were invited to enroll in a cohort phase in which the blood-pressure target was less than 130/80 mm Hg. The primary clinical outcome in the cohort phase was the progression of chronic kidney disease, which was defined as a doubling of the serum creatinine level, a diagnosis of ESRD, or death. Follow-up ranged from 8.8 to 12.2 years. RESULTS During the trial phase, the mean blood pressure was 130/78 mm Hg in the intensive-control group and 141/86 mm Hg in the standard-control group. During the cohort phase, corresponding mean blood pressures were 131/78 mm Hg and 134/78 mm Hg. In both phases, there was no significant between-group difference in the risk of the primary outcome (hazard ratio in the intensive-control group, 0.91; P=0.27). However, the effects differed according to the baseline level of proteinuria (P=0.02 for interaction), with a potential benefit in patients with a protein-to-creatinine ratio of more than 0.22 (hazard ratio, 0.73; P=0.01). CONCLUSIONS In overall analyses, intensive blood-pressure control had no effect on kidney disease progression. However, there may be differential effects of intensive blood-pressure control in patients with and those without baseline proteinuria.

Molecular and physiological characterization of dominant bacterial populations in traditional Mozzarella cheese processing

The development of the dominant bacterial populations during traditional Mozzarella cheese production was investigated using physiological analyses and molecular techniques for strain typing and taxonomic identification. Analysis of RAPD fingerprints revealed that the dominant bacterial community was composed of 25 different biotypes, and the sequence analysis of 16S rDNA demonstrated that the isolated strains belonged to Leuconostoc mesenteroides subsp. mesenteroides, Leuc. lactis, Streptococcus thermophilus, Strep. bovis, Strep. uberis, Lactococcus lactis subsp. lactis, L. garviae, Carnobacterium divergens, C. piscicola, Aerococcus viridans, Staphylococcus carnosus, Staph. epidermidis, Enterococcus faecalis, Ent. sulphureus and Enterococcus spp. The bacterial populations were characterized for their physiological properties. Two strains, belonging to Strep. thermophilus and L. lactis subsp. lactis, were the most acidifying; theL. lactis subsp. lactis strain was also proteolytic and eight strains were positive to citrate fermentation. Moreover, the molecular techniques allowed the identification of potential pathogens in a non‐ripened cheese produced from raw milk.
YAP and TAZ mediate steroid-induced alterations in the trabecular meshwork cytoskeleton in human trabecular meshwork cells

Primary open angle glaucoma is an important type of glaucoma as it is one of the most common causes of blindness. Previous studies have demonstrated that in glaucomatous patients, the human trabecular meshwork (HTM) is markedly stiffened. The purpose of the present study was to determine the regulatory role of Yes-associated protein (YAP) and transcriptional coactivator with PDZ-binding motif (TAZ) in HTM cells. Primary HTM cells were cultured with different concentrations of dexamethasone (DEX), and the expression levels of YAP and TAZ were evaluated using reverse transcription-quantitative polymerase chain reaction and western blotting. The results revealed that DEX increased the expression of YAP and TAZ in a dose-dependent manner. In addition, the western blot analysis of cytoskeleton-associated proteins revealed that the inhibition of YAP and/or TAZ using small interfering RNA resulted in the increased expression of collagen I, and decreased expression of fibronectin, laminin and collagen IV. The expression of β-catenin, a key protein in the Wnt pathway, was also observed to be regulated by YAP and TAZ. A 5-ethynyl-2′-deoxyuridine staining assay indicated that YAP and TAZ induced the proliferation of HTM cells. The investigation of cross-linked actin network formation by the HTM cells demonstrated that the knockdown of YAP and TAZ genes rescued HTM cells from cytoskeletal reorganization. Furthermore, functional evaluation of a HTM cell monolayer using a permeability assay demonstrated that the inhibition of YAP and TAZ attenuated the DEX-induced impairment of permeability. These findings suggest that YAP and TAZ play pivotal roles in the DEX-induced cytoskeletal changes of HTM cells, and reveal novel potential mechanisms for the development and progression of glaucoma.
Metabolic flux balance analysis of an industrially useful microorganism Corynebacerium glutamicum by a genome-scale reconstructed model

Microorganisms have multi-hierarchical networks such as gene, protein and metabolites in the cells. In silico genome-scale metabolic models allow us to analyze characteristics of metabolic systems of organisms. In this study, we newly reconstructed a genome-scale metabolic model of an industrially useful microorganism, Corynebacterium glutamicum, based on genome sequence annotation and physiological data. The metabolic characteristics were analyzed using flux balance analysis (FBA). We simulated the metabolic fluxes both under aerobic and oxygen deprivation conditions. The predicted growth rates and production rates of organic acids as lactate and succinate exhibited good agreement with experimental data reported in the literatures. The genome-scale metabolic model provides a better understanding for evaluating metabolic capabilities and predicting metabolic characteristics of C. glutamicum. This can be a basis for in silico analyses of metabolic network.
Systematic overview of cost-effectiveness thresholds in ten countries across four continents.

AIM To provide an overview of thresholds for incremental cost-effectiveness ratios (ICERs) representing willingness-to-pay (WTP) across multiple countries and insights into exemptions pertaining to the ICER (e.g., cancer). To compare ICER thresholds to individual country's estimated ability-to-pay. MATERIALS & METHODS We included AHRQ/USA, BIQG-GOEG/Austria, CADTH/Canada, DAHTA@DIMDI/Germany, DECIT-CGATS/Brazil, HAS/France, HITAP/Thailand, IQWiG/Germany, LBI-HTA/Austria, MSAC/Australia, NICE/England/Wales and SBU/Sweden. ICER thresholds were derived from systematic literature/website search/expert surveys. WTP was compared with ATP using Spearman's rank correlation. RESULTS Two general and explicitly acknowledged thresholds (England/Wales, Thailand), implicit thresholds in six countries and different ICER thresholds/decision-making rules in oncology were identified. Correlation between WTP and ability-to-pay was moderate. DISCUSSION Our overview supports country-specific discussions on WTP and on how to define value(s) within societies.
Nonspecific back pain in children. A search for associated factors in 14-year-old schoolchildren.

BACKGROUND Nonspecific back pain in children is nearly as common as in adults but is associated with a number of age-specific risk factors including female gender, a family history of low back pain, a high level of physical activity, and prolonged sitting. OBJECTIVE To investigate potential school-related risk factors for back pain in children, most notably schoolbag weight expressed as a percentage of body weight (relative schoolbag weight), whether the schoolbag is carried by hand or by a shoulder harness, how the child travels to and from school, and sitting positions. PATIENTS AND METHODS 123 eighth-graders, 58 girls and 65 boys, with a mean age of 14 +/- 0.6 years, completed an anonymous self-questionnaire during a school day involving six hours of classes. Their schoolbag was weighed on the same day. RESULTS Most respondents traveled to and from school in a vehicle (70%), made one trip in each direction each day (75%), and carried their schoolbag by the shoulder harness (92%). The prevalence of back pain on the study day was 27.6%, whereas the cumulative prevalence for the last 12 months was 82.9% with 16.3% of respondents reporting a single episode of pain, 57.7% recurrent pain, and 8.9% chronic pain. A need for a physician visit for back pain was reported in 18.7% of cases, and 14.6% of respondents had missed school and/or sporting activities because of back pain. Female gender was associated with current back pain (odds ratio [OR], 2.7; 95% confidence interval [CI], 1.2-6.1). A relative schoolbag weight of 20% or more was associated with a history of back pain (OR, 3.1; 95% CI, 1.0-9.2), and this effect was larger in children who traveled to and from school on foot and in those who carried their schoolbag in their hand. Sitting on the edge of the chair while completing the questionnaire was significantly associated with a history of a physician visit for back pain (OR, 3.1; 95% CI, 1.0-9.5). Neither handedness nor the position of the questionnaire on the table were significantly associated with back pain in our study population. CONCLUSIONS The findings from this cross-sectional study indicate a need for a longitudinal prospective study designed to identify etiologic and prognostic factors of back pain in adolescents, with the goal of devising preventive strategies likely to reduce the risk of low back pain in adulthood.
Characterization of Soluble Neural Cell Adhesion Molecule in Rat Brain, CSF, and Plasma

Abstract: The polypeptide composition and glycosylation of soluble isoforms of neural cell adhesion molecule (NCAM) in developing rat brain, CSF, and plasma were characterized. Soluble NCAM in rat brain consisted of several glycosylated isoforms. The degree of glycosylation was developmentally regulated. After desialylation, four polypeptides of Mr values of ∼ 190,000 (sl), 135,000 (s2), 115,000 (s3), and 110,000 (s4) were observed. Polypeptides si, s2, and s3 were also present in CSF, whereas only s3 and s4 were observed in plasma. Treatment of soluble brain NCAM with N‐glycosidase F, which removes N‐linked carbohydrates, produced polypeptides of Mr values of ∼ 190,000, 125,000, and 108,000–97,000. The monoclonal antibody OB11, which recognizes an epitope on the cytoplasmic part of transmembrane forms of NCAM, did not react with any of the soluble isoforms. Purified soluble NCAM, consisting mainly of s3, contained an N‐terminal sequence identical to that of membrane‐associated NCAM. Gel nitration of s3 indicated that it was present as a dimer under the chosen conditions. NCAM‐expressing glioma cells adhered specifically to immobilized soluble NCAM. This implies that functionally significant soluble forms of NCAM are present in the extracellular fluid.
Impact of socio-demographic variables, oral hygiene practices, oral habits and diet on dental caries experience of Indian elderly: a community-based study.

UNLABELLED A number of factors influence the caries experience and the pattern of restorative care especially in the older age group. OBJECTIVE To evaluate the dental caries experience and restorative treatment needs of an elderly Indian population and to study the impact of socio-demographic variables, oral hygiene practices, oral habits and dietary practices on them. DESIGN A community-based study. SETTING An urban area in the south zone of Delhi and a cluster of four villages in its neighbourhood. SUBJECTS A total of 1240 elderly subjects, 716 urban and 524 rural, were included in the study. RESULTS Of the 1052 dentate elderly subjects, 676 (64.2%) had decayed teeth (66.7% root caries and 33.3% coronal caries), 69 (6.6%) had filled teeth and 17 (1.6%) had recurrent decay. Restorations were indicated in 233 (22.2%) subjects, endodontic treatment in 51 (4.8%) and extractions in 424 (40.3%). Urban-rural differences in caries experience were statistically significant. Multivariate regression analysis showed that dental caries was associated with literacy level, oral hygiene practices, oral health perception and diet, while previous restorative treatment was correlated only with location (urban-rural) and presence or absence of systemic diseases. CONCLUSION Dental caries prevalence was high amongst the studied elderly population and significant differences were observed in those living in a rural compared with an urban setting. Only a small percentage of elderly had evidence of previous restorative treatment whereas their unmet treatment need was significant.

Migrations and the Settlement of Mindanao

One of the more serious obstacles to economic progress and human betterment in many of the less developed countries is the dense settlement of the present cultivated land, coupled with a rapidly increasing population. In much of southern and eastern Asia where most of the good land has been occupied by relatively dense agricultural populations for centuries and where rapidly declining mortality has sharply increased the rate of population growth, heavy land pressure is both chronic and acute. A rapidly increasing population is particularly characteristic of the Philippines where crude birth rates have remained more or less stable at about 50 per thousand since 1900 and where death rates have dropped progressively and are now about 20 per thousand. The present rate of natural increase, approximately three per cent per year, is not only higher than in most Asian countries, but is also higher than in most countries of the world. If this rate of population growth continues unabated, and the evidence suggests that it is more likely to accelerate rather than diminish in the near future, the population of the Philippines will double well before the end of the present century.
A Test of the Revised Auricular Surface Aging Method on a Modern European Population

The accurate age estimation of adults is an important step in the construction of the biological profile of skeletonized remains. The auricular surface of the ilium as it was developed in 1985 by Lovejoy et al., is one of the methods employed for age estimation. This study presents the results of a blind test of the revised auricular surface aging method developed by Buckberry and Chamberlain. A sample of 120 individuals from the Athens Collection was used to test this revised aging technique. Almost all features and composite score were positively correlated with known age‐at‐death. The calculation of bias demonstrated no obvious trend for either overestimation or underestimation of age when all individuals were pooled together. Inaccuracy showed that absolute errors of estimated ages against known ages are substantial. The data generated from this study suggest that the revised method can be reliable for age estimation on a modern European population.
Dome Division: A Viable Technique Today?

Abstract Dome division can still be regarded as a valid surgical procedure today in some particular cases of revision rhinoplasty where the scarring is so extensive as to make precise isolation of the alar cartilages impossible. The presence of asymmetry of the nasal tip, a recurrent feature in the results of rhinoplasty, constitutes the primary indication, as division makes it immediately possible to restore balance between the two domes in such cases. The technique also proves useful in cases of overprojection of the tip as a result of rhinoplasty. Moreover, the procedure has been improved by precise suturing of the cartilaginous stumps so as to avoid its frequently reported complications, arising essentially from the vulnerability of the domal arch to the distorting forces of cicatricial retraction and its resulting lack of stability over time. In this connection, the authors attach crucial importance to direct suturing of the cartilaginous stumps in accordance with a now standardized method that is easy to execute and offers lasting, stable results. This approach makes it possible to re-establish continuity of the cartilaginous domal arch in a form unquestionably closer to the physiological anatomical conformation.
Copulation, genital damage and early death in Callosobruchus maculatus

Antagonistic sexual coevolution stems from the notion that male and female interests over reproduction are in conflict. Such conflicts appear to be particularly obvious when male genital armature inflicts damage to the female reproductive tract resulting in reduced female longevity. However, studies of mating frequency, genital damage and female longevity are difficult to interpret because females not only sustain more genital damage, but also receive more seminal fluid when they engage in multiple copulations. Here, we attempt to disentangle the effects of genital damage and seminal fluid transfer on female longevity in the beetle Callosobruchus maculatus (Coleoptera: Bruchidae). Males copulating for the sixth time in succession inflicted greater levels of genital damage, but transferred smaller ejaculates in comparison with virgin males. The number of copulations performed by males was negatively related to female fecundity and positively related to female longevity, suggesting a trade-off between fecundity and longevity. However, inclusion of fecundity as a covariate revealed sperm and/or seminal fluid transfer to have a negative impact on female longevity above that caused by the fecundity–longevity trade-off. The consequences of multiple copulations on female longevity were examined. Females that mated twice laid more eggs and died sooner than those that mated once. However, incorporation of fecundity as a covariate into our statistical model removed the effect of female mating frequency on female longevity, indicating that double-mated females suffer greater mortality owing to the trade-off between fecundity and longevity. Males of this species are known to transfer very large ejaculates (up to 8% of their body weight), which may represent a significant nutritional benefit to females. However, the receipt of large ejaculates appears to carry costs. Thus, the interpretation of multiple mating experiments on female longevity and associated functional explanations of polyandry in this species are likely to be complex.
Globally bounded tracking controllers for rigid robot systems

In this note we consider tracking control of rigid robot systems under input constraints. Using the combination of two controllers we are able to obtain globally asymptotically stable closed-loop error-dynamics while keeping the applied actuator torques within in advance specified bounds. This idea is also exploited successfully in case only position measurements are available, or when parameter uncertainties call for an adaptive control scheme.
An ultrathin invisibility skin cloak for visible light

Wrap-around invisibility cloak An invisibility cloak can be used to conceal an object from view by guiding light around it. Most cloaks developed so far have bulky structures that are difficult to scale up for hiding large objects. To design a thin invisibility cloak that can be wrapped around an object such as a sheet or skin, Ni et al. designed a two-dimensional metamaterial surface. Such flexible, highly reflective materials could be manufactured at large scale to hide large objects. Science, this issue p. 1310 A metamaterial surface can be designed to operate as an invisibility skin cloak. Metamaterial-based optical cloaks have thus far used volumetric distribution of the material properties to gradually bend light and thereby obscure the cloaked region. Hence, they are bulky and hard to scale up and, more critically, typical carpet cloaks introduce unnecessary phase shifts in the reflected light, making the cloaks detectable. Here, we demonstrate experimentally an ultrathin invisibility skin cloak wrapped over an object. This skin cloak conceals a three-dimensional arbitrarily shaped object by complete restoration of the phase of the reflected light at 730-nanometer wavelength. The skin cloak comprises a metasurface with distributed phase shifts rerouting light and rendering the object invisible. In contrast to bulky cloaks with volumetric index variation, our device is only 80 nanometer (about one-ninth of the wavelength) thick and potentially scalable for hiding macroscopic objects.
Medication as Object

People experience and treat medication as though it were a person: in other words, as an object. Among the many symbolic meanings attributed to medication, this sort of personification, or object representation, is a meaning that medication is uniquely positioned to contain and convey: imbued with intentionality and influence, medication moves beyond the sphere of static, iconic representation and enters the changeable, dynamic object world of action, aim, and agency. Unlike more generic or stereotypic meanings, object representations attributed to medication may reflect the patient's specific dynamics and object relations. These representations are many and mutable, and take on shifting and overlapping forms that evolve with the analytic process. Medication may represent a third person within the framework of an analytic treatment, expanding the analytic dyad into a triad and offering new transference paradigms to explore. The defensive displacement of transferential qualities and attitudes, or split-off parts thereof, from the analyst onto medication can serve as a powerful resistance to the awareness of the transference to the analyst. Clinical examples illustrate the utility and importance of the analysis of medication as object, for both patient and analyst, with particular attention to the transference.
