Flocking in the depths of strategic iterated reasoning

Must it be the case that increasingly deep levels of strategic iterated reasoning by humans give increasingly close approximations of normative economic rationality? And if not, what might they do instead? We argue that human higher-level reasoning processes may support non-equilibrium, non-convergent "flocking" behavior. Flocking in the physical world is the sustained convergence of both the positions and velocities of the members of a group. We make the metaphor to flocking in our experiments by introducing decision environments in which participants' choices and reasoning processes function as their positions and velocities, respectively. With this definition, we demonstrate flocking in multiple group experiments over three unrelated economic games. The first game is the classic Beauty Pageant, the second is called the Mod Game, and we introduce the Runway Game. Though they three bear no formal resemblance to each other, subjects play them the same: as eliciting iterated reasoning in a way that causes individuals to converge to a "normed" depth of iterated reasoning. Our analyses and modeling suggest that flocking emerges from the way that players integrate feedback to adjust their depths of reasoning each round --- an unexpected interaction between "higher"- and "lower"-level reasoning processes. We offer new opportunities for cognitive science in behavioral game theory by speculating on the role that mental models play in helping participants represent these games as games of iterated reasoning.
Growth of lanthanum manganate buffer layers for coated conductors via a metal-organic decomposition process

Perovskite LaMnO/sub 3/ (LMO) in thin film embodiment has been identified as a potential candidate for use as a buffer layer in coated conductors. This paper delineates the process-properties relationships investigated for the metal-organic decomposition (MOD) growth of LMO thin films on bare cube-textured Ni-W tape sections. Epitaxial films of pseudocubic perovskite LMO were obtained for samples fired at 1100/spl deg/C in a humidified forming gas (Ar/4% H/sub 2/, P/sub H2O//spl sim/2 Torr) ambient atmosphere. The surface morphology, epitaxy, and composition of the films are reported.
Electrogenic arginine transport mediates stimulus‐secretion coupling in mouse pancreatic beta‐cells.

1. We have investigated the mechanism by which L‐arginine stimulates membrane depolarization, an increase of intracellular calcium ([Ca2+]i) and insulin secretion in pancreatic beta‐cells. 2. L‐Arginine failed to affect beta‐cell metabolism, as monitored by NAD(P)H autofluorescence. 3. L‐Arginine produced a dose‐dependent increase in [Ca2+]i, which was dependent on membrane depolarization and extracellular calcium. 4. The cationic amino acids L‐ornithine, L‐lysine, L‐homoarginine (which is not metabolized) and NG‐monomethyl‐L‐arginine (L‐NMMA, a nitric oxide synthase inhibitor) produced [Ca2+]i responses similar to that produced by L‐arginine. The neutral nitric oxide synthase inhibitors NG‐nitro‐L‐arginine (L‐NNA) and N omega‐monomethyl‐L‐arginine (L‐NAME) also increased [Ca2+]i. D‐Arginine was ineffective. 5. L‐Arginine did not affect whole‐cell Ca2+ currents or ATP‐sensitive K+ currents, but produced an inward current that was carried by the amino acid. 6. The reverse transcriptase‐polymerase chain reaction demonstrated the presence of messenger RNA for the murine cationic amino acid transporters mCAT2A and mCAT2B within the beta‐cell. 7. L‐Arginine did not affect beta‐cell exocytosis as assayed by changes in cell capacitance. 8. Our data suggest that L‐arginine elevates [Ca2+]i and stimulates insulin secretion as a consequence of its electrogenic transport into the beta‐cell. This uptake is mediated by the mCAT2A transporter.
EFFECT OF AGE AND GENDER ON ARRHYTHMIAS IN PATIENTS WITH CHRONIC HEART FAILURE

Background: Heart failure is a complex clinical syndrome. Modern therapeutics have led to an increase in prevalence and incidence of heart failure among the aging population. The prognosis of heart failure in women has generally been better than in men. The main cause of death in heart failure is supposed to be the sudden arrhythmic death. Arrhythmia frequency varies in both sexes. Different hormonal and electrophysiological differences exist between genders that contribute to arrhythmogenesis. Objective: To determine the effect of age and gender on arrhythmias in patients with chronic heart failure. Methods: This descriptive cross sectional study was conducted at Armed Forces Institute of Cardiology/National Institute of Heart Diseases, from April to August 2013. It involved 48-hour holter monitoring of 53 heart failure patients using holter electrocardiography recorder. Digital ECG data were analysed for type and frequency of arrhythmias. Effect of age and gender on arrhythmias was finally analysed using statistical software. Results: There was no significant association of advancing age with the rise in arrhythmia frequency. Effect of gender on arrhythmias analysis revealed that frequency of arrhythmias was significantly higher in females as compared to males (p-value < 0.05). Conclusion: Arrhythmia frequency was significantly low in men as compared to women, but the effect of age on arrhythmogenesis was not significant. Pak J Physiol 2013;9(2):11â€“4
Canine Placental Prostaglandin E2 Synthase: Expression, Localization, and Biological Functions in Providing Substrates for Prepartum PGF2alpha Synthesis1

ABSTRACT The prepartum output of PGF2alpha in the bitch is associated with increased placental PGE2-synthase (PTGES) mRNA levels. Contrasting with this is a decreased expression of PGF2alpha-synthase (PGFS/AKR1C3) in uteroplacental compartments during prepartum luteolysis, suggesting an involvement of alternative synthetic pathways in PGF2alpha synthesis, for example, conversion of PGE2 to PGF2alpha. However, because the expression and possible functions of the respective PTGES proteins remained unknown, no further conclusion could be drawn. Therefore, a canine-specific PTGES antibody was generated and used to investigate the expression, cellular localization, and biochemical activities of canine uteroplacental PTGES throughout pregnancy and at prepartum luteolysis. Additionally, the biochemical activities of these tissues involved in the conversion of PGE2 to PGF2alpha were investigated. The endometrial PTGES was localized in the uterine surface epithelium at preimplantation and in superficial and deep uterine glands, endothelial cells, and myometrium throughout pregnancy and at parturition. Placental signals were mostly in the trophoblast. The biochemical properties of recombinant PTGES protein were confirmed. Additionally, expression of two PGE2-receptors, PTGER2/EP2 and PTGER4/EP4, revealed their decreasing expression during luteolysis. In contrast, the uteroplacental expression of prostaglandin transporter (PGT) was strongly elevated prior to parturition. These localization patterns resembled that of PTGES. The increased expression of PTGES and PGT at parturition, together with the accompanying decreased levels of PGE2-receptors and the capability of canine uterine and placental homogenates to take part in the conversion of PGE2 to PGF2alpha, as found in this study, suggest that PGE2 could be used locally as a substrate for prepartum PGF2alpha synthesis in the dog.
Cefepime Versus Cefpirome: The Importance of Creatinine Clearance

Standard dosage recommendations for &bgr;-lactam antibiotics can result in very low drug levels in intensive care (IC) patients without renal dysfunction. We compared the pharmacokinetics of two fourth-generation cephalosporins, cefepime and cefpirome, and examined the relationship of drug clearance (CL) to creatinine clearance (CLCR). Two separate but similar pharmacokinetic studies (which used 2 g twice daily for each antibiotic) were conducted. Blood was sampled after an initial and a subsequent antibiotic dose. Drug plasma concentrations were measured, and pharmacokinetic analyses were conducted and compared. The pharmacokinetics of cefepime and cefpirome are similar in IC patients. Any differences in drug CL can largely be attributed to differences in CLCR. Despite normal plasma creatinine concentrations, 54% of patients’ antibiotic concentrations were less than the minimum inhibitory concentration (MIC) (4 mg/L) for >20% of the dosing interval. Thirty-four percent of patients had CLCR >144 mL/min (20% higher than the expected maximum of 120 mL/min). Only CLCR was an independent predictor of antibiotic CL. Time above MIC was predicted only by CLCR. Some IC patients have a very large CLCR, which results in very low levels of studied antibiotics. Either shortening the dosage interval or using continuous infusions would prevent low levels and keep troughs above the MIC for longer periods. In view of the lack of bedside measurement of cephalosporin levels, we suggest that more frequent use be made of CLCR to allow prediction of small concentrations clinically.
Patterning of the Autotrophic, Mixotrophic, and Heterotrophic Proteomes of Oxygen-Evolving Cyanobacterium Synechocystis sp. PCC 6803

Proteomes of an oxygenic photosynthetic cyanobacterium, Synechocystis sp. PCC 6803, were analyzed under photoautotrophic (low and high CO2, assigned as ATLC and ATHC), photomixotrophic (MT), and light-activated heterotrophic (LAH) conditions. Allocation of proteome mass fraction to seven sub-proteomes and differential expression of individual proteins were analyzed, paying particular attention to photosynthesis and carbon metabolism–centered sub-proteomes affected by the quality and quantity of the carbon source and light regime upon growth. A distinct common feature of the ATHC, MT, and LAH cultures was low abundance of inducible carbon-concentrating mechanisms and photorespiration-related enzymes, independent of the inorganic or organic carbon source. On the other hand, these cells accumulated a respiratory NAD(P)H dehydrogenase I (NDH-11) complex in the thylakoid membrane (TM). Additionally, in glucose-supplemented cultures, a distinct NDH-2 protein, NdbA, accumulated in the TM, while the plasma membrane-localized NdbC and terminal oxidase decreased in abundance in comparison to both AT conditions. Photosynthetic complexes were uniquely depleted under the LAH condition but accumulated under the ATHC condition. The MT proteome displayed several heterotrophic features typical of the LAH proteome, particularly including the high abundance of ribosome as well as amino acid and protein biosynthesis machinery-related components. It is also noteworthy that the two equally light-exposed ATHC and MT cultures allocated similar mass fractions of the total proteome to the seven distinct sub-proteomes. Unique trophic condition-specific expression patterns were likewise observed among individual proteins, including the accumulation of phosphate transporters and polyphosphate polymers storing energy surplus in highly energetic bonds under the MT condition and accumulation under the LAH condition of an enzyme catalyzing cyanophycin biosynthesis. It is concluded that the rigor of cell growth in the MT condition results, to a great extent, by combining photosynthetic activity with high intracellular inorganic carbon conditions created upon glucose breakdown and release of CO2, besides the direct utilization of glucose-derived carbon skeletons for growth. This combination provides the MT cultures with excellent conditions for growth that often exceeds that of mere ATHC.
Complex Neurochemical Microstructure of the Stria Terminalis in Infant and Adult Macaque Monkey

The stria terminalis (ST) is a major bidirectional fiber tract anchored in the amygdala and bed nucleus (BNST). Extensive investigations in rodents report a complex arrangement of neurochemically diverse neurons within the ST, but fewer data are available for non-human primates. Given the functional importance of the ST, we investigated its microarchitecture in one newborn, four infant, and two adult macaque brains, by parallel immunocytochemical series for cells or fibers. Main results are as follows: (1) The pan-neuronal marker NeuN shows scattered neurons and small neuronal clusters in both the dorsal and ventral ST, but more numerous dorsally; (2) smaller neuronal subpopulations are labeled by calretinin (CR), neuropeptide Y (NPY), calbindin (CB), and somatostatin (SOM), of which the CR + neurons are the most numerous; (3) the infant brains on average have more neurons in the ST than the adult brains, but across our sample, there is notable individual variability; and (4) fiber architectonics have a complex organization, which can be referenced to myelin-poor or myelin-dense zones. Myelin-poor zones coincide with concentrations of fibers positive for CB, CR, or tyrosine hydroxylase (TH). Neurons have been reported in other white matter domains (e.g., anterior commissure, corpus callosum, cingulum bundle, and subcortical white matter). Like these, at least some neurons within the ST may give rise to long-distance connections, and/or participate in more local functions, such as vascular regulation or axon guidance/maintenance.
Off-Target 18F-AV-1451 Binding in the Basal Ganglia Correlates with Age-Related Iron Accumulation

Off-target binding in the basal ganglia is commonly observed in the 18F-AV-1451 PET studies of the elderly. We sought to investigate the relationship between this phenomenon in the basal ganglia and iron accumulation using iron-sensitive R2* MRI. Methods: Fifty-nine healthy controls and 61 patients with Alzheimer disease and mild cognitive impairment underwent 18F-AV-1451 PET and R2* MRI studies. A correlation analysis was performed for age, 18F-AV-1451 binding, and R2* values. Results: There was an age-related increase in both 18F-AV-1451 binding in the basal ganglia and R2* values in the putamen in both the controls and the Alzheimer disease/mild cognitive impairment patients. 18F-AV-1451 binding in the basal ganglia increased with R2* values. Conclusion: Off-target 18F-AV-1451 binding in the basal ganglia is associated with the age-related increases in iron accumulation. Postmortem studies are required to further investigate the nature of this association.
Reconsidering the Impact of Environment on Long-Run Growth When Pollution Influences Health and Agents Have Finite-Lifetime

Using an overlapping generation model a la Blanchard (1985) with human capital accumulation, this article demonstrates that the influence of environment on optimal growth in the long-run may be explained by the detrimental effect of pollution on life expectancy. It also shows that, in such a case, greener preferences are growth- and welfare-improving even if the ability of the agents to learn is independent to pollution and utility is additively separable. Finally, it establishes that it is possible to implement a win-win environmental policy.
Relationship of vaginal microflora to PROM, pPROM and the risk of early-onset neonatal sepsis.

BACKGROUND Infections are among the most frequent causes of premature delivery and premature discharges of amniotic fluid. The vaginal ecosystem significantly contributes to the development of these conditions. Premature rupture of membranes (PROM) and preterm premature rupture of membranes (pPROM) are associated with an increased risk of intra-amniotic infection. The intra-amniotic infection negatively affects perinatal morbidity and mortality of newborns. OBJECTIVES Finding of relationship of vaginal microflora to PROM, pPROM and the risk of early-onset neonatal sepsis. METHODS A prospective study was implemented in 152 women with singleton gestations with PROM (n=52) and pPROM (n=47); the control group included 53 women with physiologic pregnancy and delivery at normal term without PROM. In all the women, aerobic cultivations from the vagina and cervix for Chlamydia trachomatis were provided before initiation of antibiotic treatment, the microbial picture of vagina was examined, and the cultivation examination of urine was carried out. The placenta was subjected to histopathologic examination. For the diagnosis of early-onset sepsis, we used concentrations of cytokines IL-6, IL-8, TNF-alpha, and the adhesion molecule, ICAM-1, from the venous umbilical blood taken immediately after delivery and cutting of the umbilical cord. Demonstrated early neonatal sepsis served as a further criterion. RESULTS The most frequent bacteriologic findings throughout the group were coagulase-negative Staphylococci, Ureaplasma, Candida albicans, and Streptococcus viridans. Women with a diagnosis of urinary tract infection or diabetes mellitus were excluded from the study. We found no statistically significant relationship between a specific bacterial strain and PROM and pPROM. We found a statistically significant association between the risk for intra-amniotic infection and the finding of S. viridans (p<0.001). There was also a statistically significant relationship between the microbiologic picture of the vagina VI and infection risk (p<0.002). CONCLUSIONS Based on results of the present study, it is clear that the use of cultivation and microscopic findings in the vagina and cervix for the timely diagnosis of the risk of early-onset neonatal sepsis is restricted.
A Protocol for Diagnosis and Management of Aortic Atherosclerosis in Cardiac Surgery Patients

In patients undergoing cardiac surgery, use of perioperative screening for aortic atherosclerosis with modified TEE (A-View method) was associated with lower postoperative mortality, but not stroke, as compared to patients operated on without such screening. At the time of clinical implementation and validation, we did not yet standardize the indications for modified TEE and the changes in patient management in the presence of aortic atherosclerosis. Therefore, we designed a protocol, which combined the diagnosis of atherosclerosis of thoracic aorta and the subsequent considerations with respect to the intraoperative management and provides a systematic approach to reduce the risk of cerebral complications.
Maximum flood depth characterizes above-ground biomass in African seasonally shallowly flooded grasslands

Flood depth has been frequently used to explain the distribution of plant species in seasonally flooded grasslands, but its relation with vegetation production has remained ambiguous. The relationship between flooding and above-ground biomass at the end of the flooding season and during the dry season was studied to assess the impact of reflooding on the Logone floodplain, Cameroon. Above-ground biomass of a combination of all species and of the individual perennial grasses Oryza longistaminata and Echinochloa pyramidalis showed a positive linear relationship with maximum flood depth up to 1 m. The gradient of these relationships became steeper and their fit better during the 2 y following the installation of the flooding, showing the response lag to floodplain rehabilitation. Flood duration only explained the above-ground biomass of the combination of all species and not of the individual species. Above-ground biomass data from other floodplains in the three main African geographic regions showed a similar relationship with maximum flood depth less than 1 m. Dry-season regrowth, important because of its high nutrient quality during forage scarcity, was not directly related to maximum flood depth, possibly because of its dependency on the period of burning and soil moisture. Presented data indicate that a rise of water level of 1 cm corresponds to an increase in above-ground biomass of c. 150 kg DM ha−1.
Comparative study of IGFBP properties in toad and rat sera.

The levels of IGF-I have been simultaneously measured by radioimmunoassay in samples of the toad Bufo arenarum and of normal male Wistar rats. In addition, the different fractions of IGF-I binding proteins (IGFBP) and their binding properties have been identified by ligand blot and Scatchard analysis in the serum of both species. In the toad, we have measured levels of IGF-I (2.78 +/- 0.48 ng/ml) similar to those previously reported in amphibians but far below those found in rats. IGFBP levels were estimated at 129 +/- 23 and 4249 +/- 321 pg/ml in toad and rat serum samples. Two main IGFBP fractions of 30-34 kDa, accompanied by a minor component of 24 kDa and seldom by another of 40 kDa, were identified in toad serum. In rat serum--as already reported--three bands of 40, 30, and 24 kDa were identified, the first being the main component and the last the minor one. The Scatchard analysis of a competitive binding assay showed two types of binding sites in toad serum: one of high affinity-low capacity (Ka1 = 1.6 x 10(10) M-1; R1 = 1.2 x 10(-11) M) and another with low affinity-high capacity (Ka2 = 1.9 x 10(8) M-1; R2 = 1.9 x 10(-10) M). The percentage fraction of these binding sites occupied by IGF-I was 13.5%. The figures for K1 and K2 were lower and those for R1 and R2 were higher in rat than in toad serum. The percentage fraction of occupied rat IGF binding sites was 3.6%. (ABSTRACT TRUNCATED AT 250 WORDS)
Transcriptomic profiling of the oyster pathogen Vibrio splendidus opens a window on the evolutionary dynamics of the small RNA repertoire in the Vibrio genus.

Work in recent years has led to the recognition of the importance of small regulatory RNAs (sRNAs) in bacterial regulation networks. New high-throughput sequencing technologies are paving the way to the exploration of an expanding sRNA world in nonmodel bacteria. In the Vibrio genus, compared to the enterobacteriaceae, still a limited number of sRNAs have been characterized, mostly in Vibrio cholerae, where they have been shown to be important for virulence, as well as in Vibrio harveyi. In addition, genome-wide approaches in V. cholerae have led to the discovery of hundreds of potential new sRNAs. Vibrio splendidus is an oyster pathogen that has been recently associated with massive mortality episodes in the French oyster growing industry. Here, we report the first RNA-seq study in a Vibrio outside of the V. cholerae species. We have uncovered hundreds of candidate regulatory RNAs, be it cis-regulatory elements, antisense RNAs, and trans-encoded sRNAs. Conservation studies showed the majority of them to be specific to V. splendidus. However, several novel sRNAs, previously unidentified, are also present in V. cholerae. Finally, we identified 28 trans sRNAs that are conserved in all the Vibrio genus species for which a complete genome sequence is available, possibly forming a Vibrio "sRNA core. "
Chronology and Sequence of Eruption of the Permanent Teeth in Patients with Complete Unilateral Cleft Lip and Palate

Objective To establish the chronology and sequence of eruption of the permanent teeth in subjects with complete unilateral cleft lip and palate. Design Cross-sectional. Data on children presenting complete cleft lip and palate were evaluated. Setting The study was carried out at the Hospital for Rehabilitation of Craniofacial Anomalies, Bauru, Sao Paulo, Brazil. Sample The sample comprised 477 patients with complete unilateral cleft lip and palate, aged 5 to 14 years. Of these patients, 166 were girls and 311 were boys. Results The girls presented, for all maxillary and mandibular teeth, a smaller mean age of eruption than the boys. The maxillary lateral incisor and cuspid adjacent to the cleft presented significantly higher mean ages of eruption than their homologous teeth on the noncleft side.
