AbstractThe behavioral differences in muscle use are related to the fiber type composition of the muscles among other variables. The aim of this study was to examine the degree of heterogeneity in the fiber type composition in the rat temporalis muscle. The temporalis muscle was taken from 10‐week‐old Wistar strain male rats (n = 5). Fiber types were classified by immunohistochemical staining according to their myosin heavy chain content. The anterior temporalis revealed an obvious regional difference of the fiber type distribution, whereas the posterior temporalis was homogeneous. The deep anterior temporalis showed a predominant proportion of type IIA fibers and was the only muscle portion displaying slow type fibers (< 10%). The other two muscle portions, the superficial anterior and posterior temporalis, did not differ significantly from each other and contained mainly type IIB fibers. Moreover, the deep anterior temporalis was the only muscle portion showing slow type fibers (< 10%). In the deep portion, type IIX fibers revealed the largest cross‐sectional area (1943.1 ± 613.7 µm2), which was significantly (P < 0.01) larger than those of type IIA and I + IIA fibers. The cross‐sectional area of type IIB fibers was the largest in the remaining two muscle portions and was significantly (P < 0.01) larger than that of type IIX fibers. In conclusion, temporalis muscle in rats showed an obvious heterogeneity of fiber type composition and fiber cross‐sectional area, which suggests multiple functions of this muscle.

Twelve lactating crossbred goats (Sanan × Beetal) in early lactation were divided into two groups of six each. Group I was fed on fresh berseem fodder (Trifolium alexandrinum), whereas group II was fed on berseem fodder and concentrate mixture in 1 : 1 ratio to fulfil their nutritional requirements as per National Research Council (1981). Feed intake and milk yield were recorded daily, and milk samples were collected on 0, 30, 45 and 60 days of experimental feeding for the estimation of fat, vaccenic acid, conjugated linoleic acid (CLA), vitamins A and E, and total antioxidant activity. There was no effect (P > 0.05) of dietary treatments on daily as well as total milk yield and milk fat, solids‐not‐fat and total solids, although average total CLA (mg/g fat) content in milk during the trial was higher(P < 0.01) in group I (18.92) in comparison to group II (10.94). Vitamin A content averaged 0.46 and 0.27 µg/mL and vitamin E, 1.20 and 1.38 µg/mL in milk of groups I and II, respectively, were higher in the berseem‐fed group (P < 0.01) and total antioxidant activity of milk was also higher (P < 0.01) in group I than in group II.
SPECIFICITY AND FUNCTION OF GLYCERALDEHYDE‐3‐PHOSPHATE DEHYDROGENASE IN A FRESHWATER DIATOM, ASTERIONELLA FORMOSA (BACILLARIOPHYCEAE)1
Authors: Erales Jenny , Gontero Brigitte , Maberly Stephen C. 
Published: November 2008

The plastidic glyceraldehyde‐3‐phosphate dehydrogenase (GAPDH) catalyzes the only reductive step in the Calvin cycle and exists as different forms of which GapC1 enzyme is present in chromalveolates, such as diatoms. Biochemical studies on diatoms are still fragmentary, and, thus, in this report, GAPDH from the freshwater diatom Asterionella formosa Hassall has been purified and kinetically characterized. It is a homotetrameric enzyme with a molecular mass of ~150 ± 15 kDa. The enzyme showed Michaelis–Menten kinetics with respect to both cofactors, NADPH and NADH, with a 16‐fold greater catalytic constant for NADPH. The Km for NADPH was 140 μM, the lowest affinity reported, while the catalytic constant, 815 s−1, is the highest reported. The Km for NADH was 93 μM, and the catalytic constant was 50 s−1, both are similar to reported values for other types of GAPDH. The GapC1 enzyme, like the Chlamydomonas reinhardtii A4 GAPDH, exhibits a cooperative behavior toward the substrate, 1,3‐bisphosphoglyceric acid (BPGA), with both cofactors. Mass spectrometry analysis showed that when GapC1 enzyme was purified without reducing agents, it copurified with a small protein with a mass of 8.2 kDa. This protein was recognized by antibodies against CP12. When associated with this protein, GAPDH displayed a lag that disappeared upon incubation with reducing agent in the presence of either BPGA or NADPH as a consequence of dissociation of the GAPDH/CP12 complex. Thus, as in other species of algae and higher plants, regulation of GapC1 enzyme in A. formosa may occur through association‐dissociation processes linked to dark‐light transitions.

OBJECTIVES: To identify frailty subdimensions.DESIGN: Longitudinal cohort (MacArthur Study).SETTING: Three U.S. urban centers.PARTICIPANTS: One thousand one hundred eighteen high‐functioning subjects aged 70 to 79 in 1988.MEASUREMENTS: Participants with three or more of five Cardiovascular Health Study (CHS) frailty criteria (weight loss, weak grip, exhaustion, slow gait, and low physical activity) in 1991 were classified as having the CHS frailty phenotype. To identify frailty subdimensions, factor analysis was conducted using the CHS variables and an expanded set including the CHS variables, cognitive impairment, interleukin‐6 (IL‐6), C‐reactive protein (CRP), subjective weakness, and anorexia. Participants with four or more of 10 criteria were classified as having an expanded frailty phenotype. Predictive validity of each identified frailty subdimension was assessed using regression models for 4‐year disability and 9‐year mortality.RESULTS: Two subdimensions of the CHS phenotype and four subdimensions of the expanded frailty phenotype were identified. Cognitive function was consistently part of a subdimension including slower gait, weaker grip, and lower physical activity. The CHS subdimension of slower gait, weaker grip, and lower physical activity predicted disability (adjusted odds ratio (AOR)=1.7, 95% confidence interval (CI)=1.3–2.2) and mortality (AOR=1.5, 95% CI=1.3–1.8). Subdimensions of the expanded model with predictive validity were higher IL‐6 and CRP (AOR=1.2 for mortality); slower gait, weaker grip, lower physical activity, and lower cognitive function (AOR=1.8 for disability; AOR=1.5 for mortality), and anorexia and weight loss (AOR=1.2 for disability).CONCLUSION: This study provides preliminary empirical support for subdimensions of geriatric frailty, suggesting that pathways to frailty differ and that subdimension‐adapted care might enhance care of frail seniors.
RULE CORRELATION AND CHOQUET INTEGRATION IN FUZZY INFERENCE SYSTEMS
Authors: MARQUES PEREIRA R. A. , RIBEIRO R. A. , SERRA P. 
Published: November 2008

We propose an extension of the Takagi-Sugeno-Kang (TSK) fuzzy inference system, using Choquet integration for aggregating the single rule outputs. In the new Choquet-TSK fuzzy inference system, the pairwise synergies between rules are encoded in a rule correlation matrix computed from the activation pattern of the rule base. The rule correlation matrix is then used to modulate the parameters of the Choquet integration scheme in order to compensate for the effect of rule synergies, which are present in most rule bases to a higher or lesser extent.The standard TSK fuzzy inference system remains a particular instance of the proposed Choquet-TSK extension and corresponds to the ideal case of rule independence. However, when rule correlation is present, the Choquet-TSK fuzzy inference system takes it into account when computing the final output of the system. On the basis of the rule correlation matrix, the new aggregation scheme of the Choquet-TSK fuzzy inference system attenuates the effective weight of positively correlated rules and emphasizes that of negatively correlated rules. Some case studies are discussed in order to illustrate the proposed methodology.

Abstract
We report an anomalous destruction of cholesteric blue phases I and II upon photopolymerizing a liquid crystal mixture composed of mono- and diacrylate monomers. The platelet texture characteristic of the blue phase collapsed when the sample was irradiated by a weak UV light source, while usual freezing of both blue phases I and II was obtained upon photopolymerization by a stronger light source. The phase destruction seems to be reflecting the robustness of the cubic lattice structure against external purterbations.

Published: November 2008

Abstract
A rapid small-scale peptide synthesis method was developed based on in vitro translation system. It enables us to obtain peptides within a day. Comparing the biological activity of in vitro synthesized peptides with that of chemically synthesized ones, the activity of both peptides was confirmed to be equivalent. The recovered peptides were assumed correct in their sequence through MS analysis and estimated to be more than pmoles/run. Moreover, this method could produce highly hydrophobic peptide, otherwise unavailable.

Abstract
Photosynthesis is a highly efficient solar energy transformation process. Exploiting this natural phenomenon is one way to overcome the shortage in the Earth’s fuel resources. This review summarizes the work carried out in the field of photobioreactor design via the immobilization of photosynthetically active matter within biologically inert matrices and the potential biotechnological applications of the obtained hybrid materials within the domain of solar energy to chemical energy transformation. The first part deals with the design of artificial photosynthetic reaction centers (RCs) by the encapsulation of pigments, proteins, and complexes. The action of thylakoids, chloroplasts, and whole plant cells, immobilized in biocompatible supports, in the conversion of CO2 into chemical energy, is also addressed. Finally, the latest advances in the exploitation of the bioactivity of photosynthetically active micro-organisms are explored in terms of the production of secondary metabolites and hydrogen.

Abstract
The development, survival, and reproduction of Liposcelis decolor (Pearman) (Psocoptera: Liposcelididae), an important insect pest of infested stored products, were evaluated at eight constant temperatures (20–37.5°C). Female L. decolor had four nymphal stadia, whereas males only had three nymphal stadia. Between 20 and 37.5°C, the female developmental period from egg to adult varied from 46.2 d at 20°C to 16.1 d at 35°C, and the male developmental period from egg to adult varied from 41.8 d at 20°C to 13.6 d at 35°C. Based on a nonlinear model, the lower temperature developmental thresholds of female from egg, first through fourth stadia, and combined immature stages were estimated at 12.22, 16.08, 10.93, 8.88, 12.64, and 13.02°C, the upper temperature thresholds were 42.11, 39.44, 41.27, 40.92, 39.20, and 40.52°C, respectively, whereas the lower temperature thresholds of males ranged from 11.68 to 15.86°C, and the upper temperature thresholds ranged from 40.19 to 42.04°C. The survival rate from egg to adult was 57.3% at 32.5°C, 38.4 at 20°C, and 19% at 37.5°C, respectively. After emergence, the adult had a preoviposition period that ranged from 6.8 d at 20°C to 2.3 d at 35°C. L. decolor produced the most eggs (130.4) at 32.5°C and the fewest (24.7) at 37.5°C. The population reared at 32.5°C had the highest intrinsic rate of increase (0.0609) compared with the populations reared at seven other constant temperatures. The populations reared at 35 and 37.5°C had type III survivorship pattern, whereas populations reared at other temperatures had type I survivorship curve as determined by a Weibull frequency distribution. The optimal range of temperature for L. decolor population growth was 27.5–35°C.
Microbial Diversity Associated with the Fruit-Piercing and Blood-Feeding Moth Calyptra thalictri (Lepidoptera: Noctuidae)

Published: November 2008

Abstract
Previous inventories of the diversity of lepidopteran symbionts have been limited to Eubacteria. We conducted a microbial survey of Calyptra thalictri Borkhausen (Lepidoptera: Noctuidae) by using polymerase chain reaction (PCR) primers for 16S rRNA sequences for Eubacteria, and primers for Archaea, fungi including yeast-like organisms, Microsporidia, and Wolbachia. Heads and abdomens of adult males of this fruit-piercing and blood-feeding moth were assayed separately. High-fidelity PCR and subsequent DNA analyses indicated that at least five microorganisms belonging to the α-, β-, and γ-Proteobacteria were present. Two eubacterial sequences, related to a Klebsiella sp. and a Sinorhizobium sp., were detected in the abdomens of all nine individuals sampled, and three additional sequences, two related to species in the genus Alcaligenes and one related to a Rhizobium sp., were found in some of the abdominal samples, suggesting all five could be associated with abdominal structures. No Archaea, fungi including yeast-like organisms, Microsporidia, or Wolbachia were detected. These results document the first microbial associates in a fruit-piercing and blood-feeding moth.
Environmental Conditions Affect Sperm Competition Risk in Japanese Beetles (Coleoptera: Scarabaeidae)
Authors: Switzer Paul V , Enstrom Patrick C , Schoenick Carissa A 
Published: November 2008

Abstract
Males of many species guard their mates to prevent rivals from usurping paternity of the potential offspring. Environmental conditions, such as temperature, may affect a male’s ability to guard a female effectively and consequently the amount of sperm competition that occurs. We tested whether temperature and light affected mating behavior in laboratory experiments on the Japanese beetle, Popillia japonica Newman, a species in which males guard females for minutes to many hours after mating. When tested in groups, under conditions of high temperature and high light, males guarded females for shorter periods of time and males and females both mated with more different individuals. The number of mating pairs observed at any one time, however, was lower under conditions of relatively high temperature and light, which agrees with field data and is likely due to a combination of shorter pair durations and a period of time between successive mates. Contests for females were rare, which indicates that these patterns were due to changes in the behavior of the male and/or female of the pair. To tease apart male versus female roles in these patterns, single males were given dead females for copulation and guarding. When single males mated with the dead female, light and temperature still affected guarding behavior (e.g., the shortest durations were under conditions of relatively high temperature and light), indicating that males play a major part in determining the duration of mate guarding, probably due to a change in the costs the males are incurring. However, the patterns in the dead female experiment were not identical to the patterns in the group experiment, implying that female behavior also plays a role in guarding time. Our results demonstrate that environmental conditions can have a major effect on sperm competition risk and suggest that males would benefit greatly from being able to mitigate, either morphologically, physiologically, or behaviorally, the impact of those conditions.

Published: November 2008

Abstract
Using natural venom collected from the red imported fire ant, Solenopsis invicta Buren, we determined the dose of venom necessary to kill 50% of the workers (LD50) of Argentine ants, Linepithema humile (Mayr), and several other ant species that the fire ant may encounter in California. Of the species tested, the Argentine ant was most susceptible to the venom. On a weight-adjusted basis the red imported fire ant was 330 times more resistant to the venom than the Argentine ant. In addition, the native southern fire ant, Solenopsis xyloni McCook, was significantly more susceptible to the venom than S. invicta. Formica perpilosa Wheeler was most resistant to the venom when the LD50 was not adjusted for weight, requiring a dose 684 times higher than that of the Argentine ant. When we tested synthetic venom (solenopsin A, which is the main component of S. xyloni venom) against the Argentine ant, the LD50 value was unchanged. However, both S. invicta and S. xyloni were ≈6 times more susceptible to the synthetic compound than to natural venom. Therefore, S. invicta venom is less toxic to fire ants while being just as toxic to Argentine ants as the simpler, more primitive venom of S. xyloni. Fire ant gaster flagging and venom dabbing applies enough venom to the Argentine ant to be lethal and may help explain the superior interference competition shown by the red imported fire ant.

Published: November 2008

AbstractFunctional perovskite materials gain increasing significance due to their wide spectrum of attractive properties, including ferroelectric, ferromagnetic, conducting and multiferroic properties. Due to the developments of recent years, materials of this type can conveniently be grown, mainly by pulsed laser deposition, in the form of epitaxial films, multilayers, superlattices, and well‐ordered arrays of nanoislands. These structures allow for investigations of preparation–microstructure–property relations. A wide variation of the properties is possible, determined by strain, composition, defect contents, dimensional effects, and crystallographic orientation. An overview of our corresponding work of recent years is given, particularly focusing on epitaxial films, superlattices and nanoisland arrays of (anti)ferroelectric and multiferroic functional perovskites.

Published: November 2008

AbstractFunctional organic materials with enhanced two‐photon absorption lead to new technologies in the fields of chemistry, biology, and photonics. In this article we review experimental and theoretical methodologies allowing detailed investigation and analysis of two‐photon absorption properties of organic chromophores. This includes femtosecond two‐photon excited fluorescence experimental setups and quantum‐chemical methodologies based on time‐dependent density functional theory. We thoroughly analyze physical phenomena and trends leading to large two‐photon absorption responses of a few series of model chromophores focusing on the effects of symmetric and asymmetric donor/acceptor substitution and branching.
Particle surface temperature measurements with multicolor band pyrometry

Published: November 2008

AbstractA noncontact, color‐band pyrometer, based on widely available, inexpensive digital imaging devices, such as commercial color cameras, and capable of pixel‐by‐pixel resolution of particle‐surface temperature and emissivity is demonstrated and described. This diagnostic instrument is ideally suited to many combustion environments. The devices used in this method include color charge‐coupled device (CCD), or complementary metal oxide semiconductor (CMOS) digital camera, or any other color‐rendering camera. The color camera provides spectrally resolved light intensity data of the image, most commonly for three color bands (Red, Green, and Blue,), but in some cases for four or more bands or for a different set of colors. The CCD or CMOS sensor‐mask combination has a specific spectral response curve for each of these color bands that spans the visible and often near infrared spectral range. A theory is developed, based on radiative heat transfer and camera responsivity that allows quantitative surface temperature distribution calculation, based on a photograph of an object in emitted light. Particle surface temperature calculation is corrected by heat transfer analysis with reflection between the particle and reactor wall for particles located in furnace environments, but such corrections lead to useful results only when the particle temperature is near or below the wall temperatures. Wood particle‐surface temperatures were measured with this color‐band pyrometry during pyrolysis and combustion processes, which agree well with thermocouple measured data. Particle‐surface temperature data simultaneously measured from three orthogonal directions were also mapped onto the surface of a computer generated 3‐D (three‐dimensional) particle model. © 2008 American Institute of Chemical Engineers AIChE J, 2009
