Published: February 2008

OBJECTIVE—Older adults with type 2 diabetes are more likely to fall, but little is known about risk factors for falls in this population. We determined whether diabetes-related complications or treatments are associated with risk of falls in older diabetic adults.
RESEARCH DESIGN AND METHODS—In the Health, Aging, and Body Composition cohort of well-functioning older adults, participants reported falls in the previous year at annual visits. Odds ratios (ORs) for more frequent falls among 446 diabetic participants whose mean age was 73.6 years, with an average follow-up of 4.9 years, were estimated with continuation ratio models.
RESULTS—In the first year, 23% reported falling; 22, 26, 30, and 31% fell in subsequent years. In adjusted models, reduced peroneal nerve response amplitude (OR 1.50 −95% CI 1.07–2.12], worst quartile versus others); higher cystatin-C, a marker of reduced renal function (1.38 [1.11–1.71], for 1 SD increase); poorer contrast sensitivity (1.41 [0.97–2.04], worst quartile versus others); and low A1C in insulin users (4.36 [1.32–14.46], A1C ≤6 vs. &gt;8%) were associated with risk of falls. In those using oral hypoglycemic medications but not insulin, low A1C was not associated with risk of falls (1.29 [0.65–2.54], A1C ≤6 vs. &gt;8%). Adjustment for physical performance explained some, but not all, of these associations.
CONCLUSIONS—In older diabetic adults, reducing diabetes-related complications may prevent falls. Achieving lower A1C levels with oral hypoglycemic medications was not associated with more frequent falls, but, among those using insulin, A1C ≤6% increased risk of falls.

Published: February 2008

OBJECTIVE—To examine the association between psychosocial stress and diabetes in two American Indian reservation communities (Northern Plains and Southwest).
RESEARCH DESIGN AND METHODS—The American Indian Services Utilization, Psychiatric Epidemiology, Risk and Protective Factors Project (AI-SUPERPFP), a cross-sectional probability sample survey, interviewed 3,084 randomly selected members of two American Indian tribal groups. Included were a psychiatric epidemiological interview, a physical health problems checklist, and an extensive sociodemographic section.
RESULTS—Stress was common in these reservation communities, and the stress burden was greater among those with diabetes. After adjusting for sociodemographic characteristics, early-life interpersonal trauma and community family dysfunction were significantly associated with increased odds of diabetes in the Northern Plains, while discrimination and community addiction problems were significantly associated with increased odds of diabetes in the Southwest.
CONCLUSIONS—A number of psychosocial stresses were significantly associated with increased odds of self-reported diabetes in these two American Indian communities.
Age estimation of faces: a review
Authors: Rhodes Matthew G. 
Published: February 2008

AbstractAccurate age estimation is important in a variety of settings, particularly those in which age is a condition for access to a product such as alcohol or tobacco. The current paper reviews data on the estimation of age, focusing on changes that occur to the ageing face, methodology and findings. The accumulated data suggest that age estimation of unfamiliar faces can be quite accurate, is sensitive to cues at the local and global level and may vary on the basis of group membership. Potential directions for future research are highlighted and findings are discussed with respect to their implications for policies regarding the solicitation of age identification.

Autoimmune myelopathy associated with collapsin response‐mediator protein‐5 immunoglobulin G
Authors: Keegan B. Mark , Pittock Sean J. , Lennon Vanda A. 
Published: February 2008

AbstractSeveral autoimmune myelopathies are recognized clinically. We describe 57 patients in whom serological evaluation for myelopathy of uncertain cause demonstrated collapsin response‐mediator protein 5 IgG. Most had spinal imaging and cerebrospinal fluid abnormalities and insidiously progressive presentation; some had acute monophasic or relapsing myelopathy. Initial diagnoses included multiple sclerosis, transverse myelitis, and unspecified neurodegenerative myelopathy. Most were smokers; neoplasia was discovered in 68% (most commonly small‐cell lung carcinoma and after collapsin response‐mediator protein‐5 IgG detection). Collapsin response‐mediator protein‐5 autoimmune myelopathy and occult neoplasia are important considerations in patients with insidiously progressive myelopathy, especially with known cancer risk.

Mitochondrial complex I deficiency caused by a deleterious NDUFA11 mutation
Authors: Berger Itai , Hershkovitz Eli , Shaag Avraham , Edvardson Simon , Saada Ann , Elpeleg Orly 
Published: February 2008

AbstractComplex I deficiency is the most common respiratory chain defect, clinically manifesting by severe neonatal lactic acidosis, Leigh's disease, or various combinations of cardiac, hepatic, and renal disorders. Using homozygosity mapping, we identified a splice‐site mutation in the NDUFA11 gene in six patients from three unrelated families. The patients presented with encephalocardiomyopathy or fatal infantile lactic acidemia. The mutation is predicted to abolish the first transmembrane domain of the gene product, thereby destabilizing the enzymatic complex. Mutation analysis of the NDUFA11 is warranted in isolated complex I deficiency presenting with infantile lactic acidemia or encephalocardiomyopathy. Ann Neurol 2008
Effective thermal conductivity behavior of filled vulcanized perfluoromethyl vinyl ether rubber
Authors: Wang Li , Li Fuping , Su Zhengtao 
Published: February 2008

AbstractThe effective thermal conductivity behavior of vulcanized perfluoromethyl vinyl ether (PMVE) rubber filled with various inorganic fillers was investigated and analyzed with thermal conductivity models. Experimental results showed that there was no significant improvement in the thermal conductivity of PMVE rubber if the intrinsic thermal conductivity of the fillers was greater than 100 times that of the rubber matrix, and this agreed with the prediction of Maxwell's equation. The thermal conductivity of PMVE rubber filled with larger size silicon carbide (SiC) particles was greater than that of PMVE filled with smaller size SiC because of the lower interfacial thermal resistance, and there existed a transition filler loading at about 60 vol %. It was also found that flocculent graphite was the most effective thermally conductive filler among the fillers studied. A modified form of Agari's equation with a parameter independent on the units used was proposed. © 2008 Wiley Periodicals, Inc. J Appl Polym Sci, 2008

Published: February 2008

AbstractFabrication process was successfully used to embed carbon nanotubes (CNTs) in a polylactic acid (PLA) matrix, forming a composite nanostructure. For the composites, nanoindentation is often used to characterize their mechanical properties (e.g., hardness and Young's moduli). In this experiment, the varied concentrations of CNTs in PLA were analyzed in their mechanical performance. The distribution and conformation of CNTs in the PLA were studied by X‐ray diffraction. Then, electrical characterization was performed by four‐probe method. Thermal properties were checked by TGA and DSC. Furthermore, the CNTs/PLA nanocomposites were observed by SEM. According to the experimental result, purified CNTs showed better dispersing and properties in the CNTs PLA nanocomposites. © 2008 Wiley Periodicals, Inc. J Appl Polym Sci, 2008
Synthesis, characterization and antimicrobial properties of new poly(ether‐ketone)s and copoly(ether‐ketone)s containing diarylidenecycloalkanone moieties in the main chain

Published: February 2008

AbstractA new category of linear poly(ether‐ketone)s IVa–d and copoly(ether‐ketone)s Va–f containing diarylidenecycloalkanone moieties in the main chain has been synthesized by solution polycondensation of 4,4′‐bis (chloroacetyl)diphenylether I, with different phenoxides of diarylidenecycloalkanones IIa–d. The model compound III was synthesized from the monomer I with sodium phenoxide in DMF and K2CO3, and its structure was confirmed by elemental and spectral analyses. The resulting polyketones and copolyketones were characterized by elemental and spectral analyses, beside solubility and viscometry measurements. The thermal properties of those polymers were evaluated by TGA and DTA measurements and correlated to their structural units. X‐ray analysis showed that polymers having some degree of crystallinity in the region 2θ = 5–60°. In addition, the biological screening and morphological properties of selected examples of the polymers were tested. © 2008 Wiley Periodicals, Inc. J Appl Polym Sci, 2008
Preparation of PS‐g‐PA6 copolymers by anionic polymerization of ε‐caprolactam using PS precursors with N‐carbamated caprolactam pendants as macroactivators
Authors: Liu Yao‐Chi , Xu Wei , Xiong Yuan‐Qin , Xu Wei‐Jian 
Published: February 2008

AbstractThe graft copolymer of polystyrene and polyamide 6 (PS‐g‐PA6) was investigated by anionic polymerization of ε‐caprolactam (CL), using the free radical copolymer of styrene and a kind of allyl monomer containing N‐carbamated caprolactam group as macroactivator (PS‐CCL). CL monomers were grafted onto PS‐CCL backbone via initiating N‐carbamated caprolactam (CCL) pendants along its backbone to form the graft copolymer in the presence of catalyst sodium caprolactamate. The macroactivator was characterized by Fourier‐transform infrared spectroscopy and nuclear magnetic resonance, and the graft copolymer by the selective solvent extraction technique using methanol and chloroform as solvents. PS‐g‐PA6 copolymers with different PS content were synthesized to study the effect of PS on morphology, crystallinity, dimensional stability, and thermal properties, using scanning electron microscopy, X‐ray diffraction, water absorption measurement, thermogravimetric analysis, and differential scanning calorimetry. The results show the percentage crystallinity of graft copolymer decreases with increasing PS content, but the addition of PS scarcely influences the crystalline structure of PA6. The graft copolymer has improved thermal properties and dimensional stability. © 2008 Wiley Periodicals, Inc. J Appl Polym Sci, 2008

Published: February 2008

AbstractThe aim of this project was to analyze the thermal performance of passive low‐cost housing in half‐humid tropical climate. The houses are located in Cuiabá‐MT (15.5° southern latitude), one of the hottest cities in Brazil. The data about the typology of the houses were obtained from three representative construction systems; wood, masonry, and prefabricated. The measurements had been carried out through a year, during 20 consecutive days of each season and were evaluated by three distinct methodologies: (1) analyses of previous recommendations of the construction where the envelope materials were compared with the Brazilian standard NBR 15220‐3/ 2005, (2) frequency, through dry bulb temperature with values of 18 °C and 29 °C, and (3) performance, by analysis of comfort levels and bioclimatic strategies processed by Analysis Bio 2.1.2 program in accordance to the adapted Bioclimatic Chart of Givoni for developing countries.
Preparation and Properties of Proteinaceous Microspheres Made Sonochemically
Authors: Gedanken Aharon 
Published: February 2008

AbstractIn 1990, Suslick and co‐workers developed a method in which they used high‐intensity ultrasound to make aqueous suspensions of proteinaceous microcapsules filled with water‐insoluble liquids, and demonstrated the chemical mechanism of their formation.1 Suslick's paper opened up a new field that is reviewed in the current manuscript, and this article will attempt to review the experiments that have been conducted since the discovery of this phenomenon. It will answer questions regarding the mechanism of the formation of the microspheres, whether the sonication denaturates the protein or if its biological activity is maintained, and, finally, will address possible applications of the proteinaceous microspheres. Proteinaceous microbubbles will be referred to as proteinaceous microspheres (PM) throughout this review, although they may not have a perfect spherical shape in all cases. This review will start with a short introduction to sonochemistry, although this topic is, and has been reviewed frequently.2–7 The review covers literature published until December 2006.
Mechanism of the Rhodium‐Catalyzed Asymmetric Isomerization of Allylamines to Enamines
Authors: Nova Ainara , Ujaque Gregori , Albéniz Ana C. , Espinet Pablo 
Published: February 2008

AbstractA theoretical study of the mechanism of the rhodium‐catalyzed asymmetric isomerization of allylamines to enamines by using density functional theory with the B3LYP functional leads us to discard the so far accepted nitrogen‐triggered mechanism, in which the isomerization occurs on N‐bonded intermediates and transition states, in favor of a variation of the classical allylic mechanism for olefin isomerization. The modified allylic mechanism consists of four main steps: 1) N‐coordination of the allylamine to RhI; 2) intramolecular isomerization from κ1‐(N)‐coordination to η2‐(C,C)‐coordination of the allylamine; 3) oxidative addition of C1H to form a distorted octahedral η3‐allyl complex of RhIII; and 4) hydrogen transfer to C3 (reductive C3H elimination). The two hydrogen transfer steps (oxidative addition and reductive elimination) have the highest barriers of the overall process. The oxidative addition barrier, which includes solvent effects, is 28.4 kcal mol−1. For the reductive elimination, the value in solvent is 28.6 kcal mol−1, very similar to the oxidative addition barrier.
