Published: June 2012

ABSTRACTLeaf reflectance has been used to estimate crop leaf chemical and physiological characteristics. Sugarcane (Saccharum spp.) leaf N, C, and chlorophyll levels are important traits for high yields and perhaps useful for genotype evaluation. The objectives of this study were to identify sugarcane genotypic variation in leaf hyperspectral reflectance, leaf chemical (chlorophyll, N, and C), and yield (juice sucrose content, commercial recoverable sucrose [CRS], cane yield in tonnes of cane per hectare [TCH], and sucrose yield in tonnes of sucrose per hectare [TSH]) traits and to determine relationships between leaf reflectance and these chemical and yield traits. In Stage II of the Canal Point, FL, sugarcane cultivar development program, we measured spectral reflectance and chemical traits on three leaves of the top visible dewlap from each of 87 genotypes in December 2008 and 208 and 124 genotypes in May, July, September, and October 2009 and 2010, respectively. Yield traits were determined on mature plants. Genotypic variation of leaf reflectance mainly occurred in 540 to 1200 nm. Leaf relative chlorophyll, N, C, and C to N ratio varied among genotypes and during the growing season. Highly significant calibrations were developed for leaf chemical traits using leaf reflectance (P < 0.0001). Correlations of juice sucrose, CRS, TCH, and TSH with leaf reflectance were poor. Measurement of leaf reflectance is a promising tool for estimating leaf chemical traits but not for predicting yield traits across a large number of diverse genotypes in early selection stages of a sugarcane breeding program.

Published: June 2012

AbstractThis paper focuses on the superprism effect which can be obtained in low-contrast photonic crystals. The modelling is related to the newly developed method for all-dielectric photonic crystals. This places material constraints on the simulated crystals which limit the refractive index difference to 0.1 for all-glass photonic crystals and 0.6 for air-glass structures and forces us to focus on hexagonal lattices. The simulations show the existence of superprism effect in both types of structure for realistic glasses. In both cases various linear filling factors are studied in order to maximize the frequency range of the superprism effect. For the air-F2 glass structure it reaches 0.108 normalized frequencies and for the air-NC21 glass structure it reaches 0.99 normalized frequencies for TM polarization. For the double glass structures, the largest range is for the F2/NC21 photonic crystal and spans 0.012 normalized frequencies. In the F2/NC21 crystal the frequency range reaches 0.005 for TE polarization.

Published: June 2012

In this research work some mathematical models have been simulated to estimate the regression coefficients, which are also known as Angstrom coefficients, with monthly and daily average solar radiation on horizontal surface using bright sunshine hours. This study of solar energy, information on solar radiation and its components at a given location is very essential for scientists, engineers, architects, agriculturists and hydrologists for various applications such as measuring aerosol optical thickness, solar heating, cooking, drying and interior illumination of buildings. But, for developing countries like Bangladesh, we have limitation of sophisticated measuring instruments. So, we have used some latitude based empirical models to calculate an important solar radiation geometry parameter- Angstrom Coefficients for Bangladesh without any help of costly instruments.

Published: June 2012

Leaves, one year old stems and buds were used as explants. WPM, B5, MS, half and one-fourth strength MS with 2,4-?D, NAA, IBA, IAA and picloram 2, 5 and 10 mg/l were used for callus induction. Investigation into the seasonal effect on callus regeneration and explants browning was carried out in mid-April until September. Results showed that washing with sterile distilled water for one hour after surface sterilization was the best treatment for browning inhibition of explants than other treatments. Leaf explants have best callus formation. MS with 8 g/l agar had strong effect on callus formation. Culture for callus formation in May and June found to be higher than other months. 2,4-D, NAA and 10 mg/l picloram significantly enhanced callus formation. Leaf and bud explants sampling in April to May did not show any endophyte contamination but leaf explants in June until September, specially the one year old stems, showed intensive contamination.

Published: June 2012

DNA fingerprinting and genetic diversity of four Bangladesh Rice Research Institute (BRRI) hybrid varieties and their parental lines were carried out. A total of 73 microsatellite markers were tested for screening the genotypes. Among the 73 amplified products, 37% had polymorphic bands showing 81 alleles. The number of alleles per locus ranged from two (RM10) to eight (RM327), where average allele number was 4.333. The Polymorphism Information Contents (PIC) lied between 0.337 (RM10) and 0.852 (RM327). RM327 was the most robust marker providing the highest PIC value (0.852). Pair-wise genetic dissimilarity coefficient interaction showed that BRRI hybrids two was the most genetically distant from each other whereas BRRI hybrids one, three, four and their respective parents were very close. Cluster analysis based on Dices similarity coefficient UPGMA system grouped BRRI hybrid and their parental lines into four major clusters at 0.41 cut off similarity coefficient. Four BRRI hybrid varieties grouped into four distinct clusters along with their component lines indicating their genetic closeness.

Analyse du Discours à Entrée Lexicale (A.D.E.L.) : le renouveau par la sémantique ?
Authors: Née Émilie , Veniard Marie 
Published: June 2012

Cet article fait le point sur les travaux en analyse du discours qui privilégient des entrées lexicales, en revenant au projet d’Analyse du Discours à Entrée Lexicale (A.D.E.L.) tel que l’a défini J.-B. Marcellesi (1976). En tutoyant l’histoire de l’analyse du discours (Mazière 2005, Paveau et Rosier 2005), nous retraçons le cheminement des études à entrée lexicale, depuis la lexicologie sociolinguistique jusqu’aux travaux intégrant l’interdiscours, avant de revenir sur ce qui fait la spécificité de l’A.D.E.L telle que nous l’entendons, c’est-à-dire l’articulation entre le lexique et l’énoncé, voie ouverte par J. Dubois (1969). En soulignant les limites des études de vocabulaire dans l’étude des textes et en introduisant l’énoncé contre le mot, ce dernier, en effet, a ouvert à l’analyse du discours une voie qui lui est propre, qui la distingue d’autres approches (histoire, sociologie ou, plus récemment, sciences de l’information et de la communication) et qui illustre un des postulats linguistiques de l’AD : l’articulation du sens à la syntaxe. Ainsi, en cherchant à relier le lexique aux autres dimensions de la discursivité, le principe paradoxal sur lequel s’appuie une recherche par les mots est que ces derniers sont amenés à être dépassés, de par leur solidarité avec la chaîne syntagmatique et avec le discours. C’est ce principe qui est à la base de l’ADEL et que nous cherchons à modéliser dans une perspective sémantique. Nous défendons l'idée que des avancées récentes en sémantique, telles qu'une approche praxéologique ou la sémantique des constructions, peuvent rendre compte de l'articulation du sens au discours, ce que nous illustrons à travers deux études de cas.
Une réception japonaise de Bergson : Miki Kiyoshi et l'empirisme intégral
Authors: Ebersolt Simon 
Published: June 2012

Résumé La philosophie d’Henri Bergson fait l’objet d’une réception passionnée au Japon au début des années 1910, mais, étant donné un contexte spiritualiste critiquant la raison, elle est généralement interprétée comme un irrationalisme opposant l’intuition à l’intelligence. Le principal problème de la réception de 1941, à l’occasion de la mort de Bergson, est alors de montrer comment l’intuition en réalité collabore avec l’intelligence. Par l’examen de la notion d’« empirisme intégral », Miki Kiyoshi (1897-1945), qui a développé une philosophie dialectique influencée par Karl Marx et Martin Heidegger, tente d’y apporter une solution en rapprochant l’intuition bergsonienne de l’imagination kantienne.

Mirror-image Trigger Thumb in Dichorionic Identical Twins
Authors: Wang Eric D. , Xu Xiaoti , Dagum Alexander B. 
Published: June 2012

The congenital vs acquired etiology of pediatric trigger thumb is the subject of considerable debate. Existing case reports of bilateral presentation in identical twins and first-degree familial association support the congenital hypothesis. However, prospective studies have yet to report a neonate presenting with this anomaly at birth. This article describes the first known set of dichorionic, monozygotic identical twins with unilateral trigger thumbs, affecting contralateral (mirror-image) hands and with asynchronous age at presentation (11 months and 18 months, respectively).
Pediatric trigger thumb is caused by a mismatch between the flexor pollicis longus tendon and its A1 synovial pulley. Four sets of twins have been previously reported in the literature with trigger thumb. Of these, 3 sets were monozygotic twins who had bilaterally affected thumbs. Together with the absence of trauma, a congenital etiology was suggested. The fact that pediatric trigger thumb is generally seen several months after birth was felt to be due to infants holding their thumbs clutched in their palms until 6 months. However, no confirmed cases of trigger thumb have been diagnosed at birth in several large prospective studies of newborns.
In the current case, the asynchronous presentation of unilateral trigger thumbs in identical twins does not support a solely congenital cause. Furthermore, the mirror-image presentation contradicts current embryological understanding of the temporal course of twinning and the determination of laterality. Thus, a multifactorial etiology is supported with both a genetic and acquired component affecting the development of this condition.
Alterations of the Anterior Lens Capsule in Vitrectomized Eyes With Silicone Oil Tamponade
Authors: Citirik Mehmet , Sargon Mustafa F. , Has Semiha , Bilgin Selma 
Published: June 2012

BACKGROUND AND OBJECTIVE:
To investigate the electron microscopic findings of the anterior lens capsule in vitrectomized eyes with silicone oil tamponade.

PATIENTS AND METHODS:
Ten eyes of 10 consecutive patients aged 39 to 74 years who had cataract surgery combined with silicone oil removal from December 2006 to May 2009 were included in the study. The control group included 10 patients with cataract extraction and intraocular lens implantation without history of systemic or other ocular disease. All anterior capsules underwent electron microscopic examination of the anterior lens capsule.

RESULTS:
During the capsulorhexis, the anterior lens capsule was removed. In the silicone oil tamponade group, silicone oil droplets were detected on the posterior surface of the anterior lens capsule in 5 cases (50%) and surface irregularities, pits, and depressions were present in the posterior surface of the anterior lens capsules in all cases.

CONCLUSION:
Silicone oil droplets may infiltrate the lens capsule, especially in diabetic patients. Surface irregularities may be associated with posterior fibrous pseudometaplasia produced by lens epithelial cells under the anterior lens capsule.
Surfactant‐Free One‐Step Synthesis of Dual‐Functional Polyurea Microcapsules: Contact Infection Control and Drug Delivery
Authors: He Wei , Gu Xiaochen , Liu Song 
Published: June 2012

AbstractSurface functionalized polyurea microcapsules (MCQ) are synthesized in one step. Dimethyl‐dodecyl‐(5‐hydroxy‐pentyl)‐ammonium bromide (DAB), a hydroxyl‐end‐capped quaternary ammonium salt, is synthesized and adopted as a new surfmer for the synthesis of MCQ. It is confirmed by fluorescein adsorption that DAB is covalently bonded to MCQ. The so‐formed MCQ possess dual‐functionality: contact infection control and sustained drug delivery. Agar diffusion antimicrobial tests confirm successful inhibition of multi‐drug‐resistant E. coli by MCQ alone instead of by leaching of free quaternary ammonium salts. Furthermore, few E. coli colonies survive on an agar plate coated with 3–4 layers of MCQ. Dissolution tests show a typical first‐order release profile of courmarin‐1, a model dye, from MCQ.

Published: June 2012

AbstractBackgroundThe objective of this study was to determine the factors associated with sun exposure behaviors among Operating Engineers (heavy equipment operators).MethodsOperating Engineers (N = 498) were asked to complete a cross‐sectional survey. Linear and logistic regression analyses were used to determine health behavioral, perceptional, and demographic factors associated with sun exposure behavior (sun burns, blistering, use of sunscreen, and interest in sun protection services).ResultsAlmost half reported two or more sunburns/summer and the median times blistering was 2 with a range of 0–100. About one‐third never used sun block, while just over one‐third rarely used sun block. Almost one‐quarter were interested in sun protection guidance. Multivariate analyses showed that perceptions of skin type, alcohol problems, fruit intake, BMI, sleep quality, age, sex, and race were significantly associated with at least one of the outcome variables (P < 0.05).ConclusionsOperating Engineers are at high risk for skin cancer due to high rates of exposure to ultraviolet light and low rates of sun block use. Subgroups of Operating Engineers are particularly at risk for sun damage. Interventions are needed to decrease sun exposure among Operating Engineers. Am. J. Ind.

Serotonin transporter5‐HTTLPRgenotype moderates the effects of childhood adversity on posttraumatic stress disorder risk: A replication study
Authors: Xie Pingxing , Kranzler Henry R. , Farrer Lindsay , Gelernter Joel 
Published: June 2012

AbstractWe reported that the5‐HTTLPRpolymorphism in the promoter region of the serotonin transporter gene (SLC6A4) moderates the effect of childhood adversity on posttraumatic stress disorder (PTSD) risk [Xie et al. (2009); Arch Gen Psychiatry 66 (11): 1201–1209]. In the present study, we considered 5,178 subjects (a group with generally high substance dependence comorbidity, as for our previous study) using similar methodology to replicate our previous results. We used logistic regression analyses to explore the interaction effect of5‐HTTLPRgenotype and childhood adversity on PTSD risk. We found that, as reported in our previous study, in individuals with childhood adversity, the presence of one or two copies of theSallele of5‐HTTLPRincreased the risk to develop PTSD. This gene–environment interaction effect was present in European Americans (EAs), but not in African Americans (AAs; EAs, OR = 1.49, 95% CI = 1.07–2.08,P = 0.019; AAs, OR = 0.90, 95% CI = 0.60–1.35,P = 0.62). The statistical power to detect this interaction effect was increased when data were combined with those from our previous study [Xie et al. (2009); Arch Gen Psychiatry 66 (11): 1201–1209]. The findings reported here replicate those from our previous work, adding to a growing body of research demonstrating that the5‐HTTLPRgenotype moderates risk for anxiety and depression phenotypes in the context of stress and adverse events. © 2012 Wiley Periodicals, Inc.
Defining genetically meaningful language and personality traits in relatives of individuals with fragile X syndrome and relatives of individuals with autism
Authors: Losh Molly , Klusek Jessica , Martin Gary E. , Sideris John , Parlier Morgan , Piven Joseph 
Published: June 2012

AbstractSubstantial phenotypic overlap exists between fragile X syndrome (FXS) and autism, suggesting thatFMR1(the gene causing FXS) poses a significant risk for autism. Cross‐population comparisons of FXS and autism therefore offer a potentially valuable method for refining the range of phenotypes associated with variation inFMR1. This study adopted a broader phenotype approach, focusing on parents who are at increased genetic liability for autism or FXS. Women who were carriers ofFMR1in its premutation state were compared with mothers of individuals with autism, and controls in an attempt to determine whether subtle features of the broad autism phenotype may express at elevated rates amongFMR1premutation carriers. The principal personality and language features comprising the broad autism phenotype (i.e., rigid and aloof personality, and particular patterns of pragmatic language use) were assessed among 49 premutation carriers who were mothers of individuals with FXS, 89 mothers of individuals with autism, and 23 mothers of typically developing individuals. Relative to controls, the autism and premutation parent groups showed elevated rates of certain personality and language characteristics of the broad autism phenotype. Findings suggest partially overlapping personality and language profiles among autism and premutation parent groups, with rigid personality style and patterns of pragmatic language use emerging as features most clearly shared between groups. These results provide further evidence for the overlap of autism and FXS, and may implicateFMR1in some of the subtle features comprising the broad autism phenotype. © 2012 Wiley Periodicals, Inc.

AbstractThe β‐amyloid peptide may play a central role in Alzheimer's disease (AD) pathogenesis. We have evaluated variants in seven Aβ‐degrading genes (ACE, ECE1, ECE2, IDE, MME, PLAU, and TF) for association with AD risk in the Genetic and Environmental Risk in Alzheimer's Disease Consortium 1 (GERAD1) cohort, and with three cognitive phenotypes in the Lothian Birth Cohort 1936 (LBC1936), using 128 and 121 SNPs, respectively. In GERAD1, we identified a significant association between a four‐SNP intragenic ECE1 haplotype and risk of AD in individuals that carried at least one APOE ε4 allele (P = 0.00035, odds ratio = 1.61). In LBC1936, we identified a significant association between a different two‐SNP ECE1 intragenic haplotype and non‐verbal reasoning in individuals lacking the APOE ε4 allele (P = 0.00036, β = −0.19). Both results showed a trend towards significance after permutation (0.05 < P < 0.10). A follow‐up cognitive genetic study evaluated the association of ECE1 SNPs in three additional cohorts of non‐demented older people. Meta‐analysis of the four cohorts identified the significant association (Z < 0.05) of SNPs in the ECE‐1b promoter with non‐verbal reasoning scores, particularly in individuals lacking the APOE ε4 allele. Our genetic findings are not wholly consistent. Nonetheless, the AD associated intronic haplotype is linked to the 338A variant of known ECE1b promoter variant, 338C>A (rs213045). We observed significantly less expression from the 338A variant in two human neuroblastoma cell lines and speculate that this promoter may be subject to tissue‐specific regulation. © 2012 Wiley Periodicals, Inc.

AbstractObjective:Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease that is characterized by the selective loss of upper and lower motoneurons. Although >100 different Cu, Zn superoxide dismutase (SOD1) mutations have been identified in ALS patients, it remains controversial whether all of them are disease‐causative mutations. Therefore, it is necessary to develop molecular mechanism‐based diagnosis and treatment of ALS caused by SOD1 mutations.Methods:We previously reported that 3 pathogenic mutations of SOD1 cause chronic endoplasmic reticulum (ER) stress by inducing the binding of SOD1 to Derlin‐1, a component of the ER homeostatic machinery. Here, we systematically analyzed 132 SOD1 mutants and found that most have a constitutively exposed Derlin‐1–binding region (DBR) that is occluded in the wild‐type protein. To develop the novel molecular mechanism‐based antibody that can specifically recognize the aberrant structure of toxic SOD1 mutants, we generated the monoclonal antibody against the DBR.Results:MS785, a monoclonal antibody generated against the DBR, distinguished most ALS‐causative SOD1 mutants from both wild‐type and nontoxic mutants. Moreover, MS785 recognized endogenous SOD1 in B lymphocytes derived from 14 ALS patients carrying SOD1 mutations but not from 11 healthy controls.Interpretation:This is the first study to address the common property of all ALS‐causative SOD1 mutants. MS785 is the first molecular mechanism‐based antibody that was shown to be able to distinguish ALS‐linked toxic SOD1 mutants from both wild‐type and nontoxic mutants. MS785 may thus become an innovative tool for the diagnosis of ALS. ANN NEUROL 2012;72:739–749
