Effect of experimental parameters on the formation of chitosan–poly(acrylic acid) nanofibrous scaffolds and evaluation of their potential application as DNA carrier
Authors: Wang Jian‐Wen , Chen Ching‐Yi , Kuo Yi‐Ming
Published: October 2009

Gene delivery from tissue engineering scaffolds has demonstrated the ability to promote gene transfer and stimulate new tissue formation. In this article we report a novel nanofibrous scaffold based on polyelectrolyte complexes as a vehicle for delivery of DNA. When polycation chitosan (CS) was dropped into polyanion poly(acrylic acid) (PAA) suspension and freeze‐dried, CS‐PAA nanofibrous scaffold with diverse microstructure would be formed under different experimental conditions. The nanofiber size was affected by the CS molecular weight, the concentration of CS, the volume ratio of CS to PAA, the reaction temperature, the incubation time, and the final pH of the suspension as well. By using adipic acid as branch promoter, adjusting the pH value of the CS solution to 3, and then dropping CS into the PAA solution at a ratio of 3 : 1, a nanofibrous structure with average diameter 140 nm is obtained after the suspension is freeze‐dried. These nanofibrous scaffolds were nontoxic and can encapsulate plasmid DNA very well. Transgenic expression in human dermal fibroblasts seeded on the nanofibrous scaffolds was significant after 14 days compared to lipofectamine controls. This result indicates that CS‐PAA nanofibrous scaffold have favorable characteristics for nonviral gene delivery to mammalian cell, and have the potential to enhance gene transfer in tissue engineering. © 2009 Wiley Periodicals, Inc.

Authors: de Lima Viviane , da Silva Pelissoli Nicole , Dullius Jeane , Ligabue Rosane , Einloft Sandra
Published: October 2009

This work presents a comparative study between alternative catalytic systems, metal‐β‐diketones complexes (iron, copper, chromium, and tin), and the commercial catalyst dibutyltin dilaurate, DBTDL, in the polyurethanes synthesis obtained from isophorone diisocyanate (IPDI) and polyols as polypropyleneglycol/diethyleneglycol and 1,6‐hexanodiol polyadipate (polyester A‐Mn = 2000 g/mol and polyester B‐Mn = 1000 g/mol) reactions. The polyurethanes synthesis was followed by the IPDI consumption in time, verified by infrared spectroscopy (FTIR) through the decrease of free NCO characteristic band at 2300–2200 cm−1. The FTIR data was used to determine the polyurethanes formation kinetic behavior. It was verified that for the reactions with polyethers excess, DBTDL catalyst was more effective when compared to metal‐β‐diketones complexes, while for the reactions with polyester, A and B, the metal‐β‐diketones complexes were more effective. © 2009 Wiley Periodicals, Inc.

Effects of inorganic nano‐particles on plasticizers migration of flexible PVC
Authors: Yang Baohong , Bai Yongping , Cao Yingjie
Published: October 2009

The influences of nano‐particles (nano‐sized CaCO3 and nano‐sized SiO2) on plasticizers volatility, solvent extraction stability, and exudation stability of flexible PVC were studied. The results showed that nano‐particles could reduce migration of plasticizers, thus improved the ability of anti‐migration of flexible PVC. Further more, nano‐sized SiO2 shows excellent property than nano‐sized CaCO3 in resistance migration of plasticizers. © 2009 Wiley Periodicals, Inc. J Appl Polym Sci, 2010
Preparation and characterization of PVA films with magnetic nanoparticles: The effect of particle loading on drug release behavior
Authors: Bertoglio Paula , Jacobo Silvia E. , Daraio Marta E.
Published: October 2009

This article deals with the drug release behavior of theophylline (Th) from poly(vinyl alcohol) (PVA) hydrogels, prepared with magnetic nanoparticles at different particle loadings. These biocompatible matrices were obtained by incorporating different amounts of an aqueous ferrofluid into PVA hydrogels, loaded with Th as a marker for drug‐delivery studies. PVA films with magnetic particles proved to be magnetic field‐responsive materials as the drug release decreased through the application of a relative low and uniform magnetic field for particle concentrations of 0.9% w/w or higher. Moreover, the percentage of restriction of drug release is found to be correlated with particle loading. The in vitro release profiles were analyzed by applying a semiempirical power law to obtain the kinetic parameters. The value of the release exponent was found to be in the range 0.54–0.56 in all experiments, which thus indicates a predominant diffusional mechanism for drug release from these smart magnetic hydrogels. This effect suggests the possibility of modulating the release behavior by controlling the particle content in the preparation of the composites. © 2009 Wiley Periodicals, Inc. J Appl Polym Sci, 2010
Chemical and mechanical characterization of two South‐American plant fibers for polymer reinforcement: Caranday Palm and Phormium
Authors: Krause Sammartino L. E. , Aranguren M. I. , Reboredo M. M.
Published: October 2009

Two South‐American plants, native Caranday Palm and Phormium, were characterized to investigate their potential as a source of fibers for the preparation of polymer composites. The plant leaves were subjected to different chemical characterizations, whose results were further corroborated by Fourier transformed infrared spectroscopy and Thermogravimetric analysis techniques. The results showed that leaves from Caranday Palm have higher cellulose content than Phormium leaves. The tensile testing of the technical fibers showed that they may be suitable for use in the production of polymer composites, as the properties are comparable to those of other vegetable technical fibers. Preliminary results on the effect of the incorporation of Caranday Palm fibers into polypropylene lead to a composite of improved modulus and relatively low density. © 2009 Wiley Periodicals, Inc.

Chemical modification of a chloromethylated polystyrene (CMPSt) was performed by the reaction of the chlorometyl group with the PH bond of 9,10‐dihydro‐oxa‐10‐phosphaphenanthrene‐10‐oxide. A kinetic study on the phosphorylation reaction of CMPSt with different chlorine contents and/or different molecular weighs was reported. The obtained polymers bearing phosphorus containing cyclic bulky groups were characterized by analytical methods, FTIR and 1H NMR spectroscopy. Their thermal behavior and flammability were also studied. © 2009 Wiley Periodicals, Inc. J Appl Polym Sci, 2010
Control of release characteristics in pH‐sensitive poly(vinyl alcohol)/poly(acrylic acid) microcapsules containing chemically treated alumina core
Authors: Yun Jumi , Kim Hyung‐Il
Published: October 2009

The pH‐sensitive poly(vinyl alcohol)/poly(acrylic acid) hydrogel microcapsules containing vitamin B12‐loaded Al2O3 core were prepared with a three‐step emulsion polymerization. Al2O3 was chemically treated with HCl or NaOH solutions at room temperature for 24 h to modify the binding properties with vitamin B12. The colon‐targeted release characteristics of vitamin B12 from the microcapsules were evaluated at different pHs. These microcapsules showed the faster and larger release of vitamin B12 due to the high swelling of microcapsule shell as the pH was changed into more basic condition. However, these microcapsules showed the slower and less release of vitamin B12 as the acid value of Al2O3 increased due to the strong binding interaction between Al2O3 core and vitamin B12 even though the initial loading of vitamin B12 was higher. © 2009 Wiley Periodicals, Inc.

Gene expression profiling in the fetal cardiac tissue after folate and low‐dose trichloroethylene exposure
Authors: Caldwell Patricia T. , Manziello Ann , Howard Jamie , Palbykin Brittany , Runyan Raymond B. , Selmin Ornella
Published: October 2009

BACKGROUND: Previous studies show gene expression alterations in rat embryo hearts and cell lines that correspond to the cardio‐teratogenic effects of trichloroethylene (TCE) in animal models. One potential mechanism of TCE teratogenicity may be through altered regulation of calcium homeostatic genes with a corresponding inhibition of cardiac function. It has been suggested that TCE may interfere with the folic acid/methylation pathway in liver and kidney and alter gene regulation by epigenetic mechanisms. According to this hypothesis, folate supplementation in the maternal diet should counteract TCE effects on gene expression in the embryonic heart. APPROACH: To identify transcriptional targets altered in the embryonic heart after exposure to TCE, and possible protective effects of folate, we used DNA microarray technology to profile gene expression in embryonic mouse hearts with maternal TCE exposure and dietary changes in maternal folate. RESULTS: Exposure to low doses of TCE (10 ppb) caused extensive alterations in transcripts encoding proteins involved in transport, ion channel, transcription, differentiation, cytoskeleton, cell cycle, and apoptosis. Exogenous folate did not offset the effects of TCE exposure on normal gene expression, and both high and low levels of folate produced additional significant changes in gene expression. CONCLUSIONS: A mechanism by which TCE induces a folate deficiency does not explain altered gene expression patterns in the embryonic mouse heart. The data further suggest that use of folate supplementation, in the presence of this toxin, may be detrimental and not protective of the developing embryo Birth Defects Research (Part A), 2010. © 2009 Wiley‐Liss, Inc.

Patientennahe Labordiagnostik. Point‐of‐Care‐Testing
Authors: Gauglitz Günter , Luppa Peter B.
Published: October 2009

Patientennahe Diagnostik gewinnt in den letzten Jahren zunehmend Bedeutung in der Notfallmedizin, bei der Intensivmedizin und auch bei der Patientenselbstkontrolle. Neben Anforderungen an für solche Aufgaben geeignete Geräte und Informationen zu den Aufgaben von POCT sind Beipiele für Anwendungen dargestellt. Insbesondere auf optische Methoden wie Totale Interne Fluoreszenzreflexion und Reflektometrische Interferenzspektroskopie wird als Detektionsprinzipien eingegangen. Die Grundlagen von Biosensoren und von Bestimmungsverfahren für die Nachweise von klinisch relevanten Krankheitsmarkern werden gegeben.
Antikörper – neue Krebsmedikamente. Gezielt wirksame Biomedizin
Authors: Hasmann Max , Klein Christian , Kresse Georg‐Burkhard
Published: October 2009

Monoklonale Antikörper (mAbs) sind multifunktionale Moleküle, die spezifisch Antigene binden und Immuneffektorfunktionen auslösen können. Eine Reihe von mAbs – wie Rituximab, Trastuzumab, Cetuximab und Bevacizumab – wird bereits erfolgreich zur Behandlung von Krebserkrankungen eingesetzt und hat zu großen Fortschritten in der Tumortherapie geführt. Neue Technologien (Antikörper‐Konjugate, bispezifische und glykomodifizierte Antikörper, Antikörper‐Fragmente) können zu weiteren Fortschritten führen.
Genetik des Herzinfarktes. Der lange Weg von der positiven Familienanamnese zum Gen
Authors: Wagner Arnika K. , Schunkert Heribert , Erdmann Jeanette
Published: October 2009

Das Auftreten eines Herzinfarkts bei einem Verwandten ersten Grades vor dem 55. Lebensjahr sowie mehrere Ereignisse in der weiteren Familie ist ein kardiovaskulärer Risikofaktor. Zwillings‐ und Familienstudien machten deutlich, dass sich das Risiko, einen Infarkt zu erleiden bei monozygoten Zwillingen um bis zu 8‐fach erhöhen kann. Die klassischen Risikofaktoren wie ein hoher Cholesterinspiegel, Bluthochdruck und Diabetes Mellitus sind zudem teilweise genetisch determiniert; es wurden bereits mehrere genetische Varianten entdeckt, die zusätzlich zum genetischen Risiko kardiovaskulärer Erkrankungen beitragen. Mittels Genomweiter Assoziationsstudien konnten ohne A‐priori‐Hypothese mehrere neue Genvarianten identifiziert werden, die durch noch unbekannte Mechanismen zur Manifestation der Koronanen Herzkrankheit beitragen.
Bier für helle Flaschen
Authors: Feil Sylvia
Published: October 2009

Ein kühles Bier, am besten frisch gezapft, schmeckt zu deftigen Gerichten oder einfach pur. Geworben wird mit Mineralstoffen und Vitaminen, die alkoholfreie Varianten gar zum isotonischen Getränk machen. Da überrascht die Idee, Vitamin B2 aus dem Bier zu filtern. Und am besten auch gleich noch aus Milch und Fruchtsäften. Grund dafür ist der Lichtgeschmack, der je nach Getränk anders ausfällt.
Testing for order among K populations: theory and examples
Authors: Davidov Ori , Herman Amir
Published: October 2009

Testing for stochastic order among K populations is a common and important problem in statistical practice. It arises in the analysis of both planned experiments and observational studies. The authors develop a new nonparametric test for order among K populations that can accommodate any stochastic ordering. The test is based on a maximally selected chi‐bar‐square statistic. The authors find its limiting distribution and use simulations to derive critical values. Three important examples are used to illustrate the applicability of the general method. The authors find that the new tests outperform the existing methods in many practical cases. The Canadian Journal of Statistics 38: 97–115; 2010 © 2009 Statistical Society of Canada
Current applications and future prospects of fine‐needle aspiration biopsy of locoregional lymph nodes in the management of breast cancer
Authors: Krishnamurthy Savitri
Published: October 2009

Staging of disease is routine in the evaluation of patients newly diagnosed with breast cancer. Assessment of palpable and/or nonpalpable locoregional lymph nodes is an important component of the initial staging. Ultrasound (US) is the favored imaging modality for the initial investigation of lymph nodes and results in a significant increase in the specificity of the overall evaluation when used in conjunction with fine‐needle aspiration (FNA). This review provides a concise summary, based on published literature, of the current applications and future prospects of FNA biopsy of locoregional lymph nodes in the initial staging and subsequent surgical management of patients with breast cancer. Patients undergo either sentinel lymph node (SLN) biopsy or complete axillary lymph node dissection, based on whether the axillary lymph node status is determined to be negative or positive in the initial staging process. The status of lymph nodes in the supraclavicular, infraclavicular, and internal mammary regions provides more accurate staging information and also impacts subsequent surgical management. The identification and evaluation of intramammary lymph nodes can add value in the overall assessment of patients with breast cancer. The feasibility of noninvasive imaging modalities for SLN mapping in animal models has indicated a good potential for FNA biopsy in the subsequent investigation of SLNs identified noninvasively in humans.

Epithelioid angiosarcoma: A neoplasm with potential diagnostic challenges
Authors: Lin Christine F. , DeFrias Denis , Lin Xiaoqi
Published: October 2009

Epithelioid angiosarcomas are extremely rare tumors associated with poor prognosis and early metastases. Its epithelioid cytomorphology and limited vasoformation make it difficult to distinguish from more common malignancies, such as, carcinoma. This can be a potential diagnostic pitfall for the cytopathologist. In this report, the patient is a 24‐year‐old man presenting with testicular pain, a pelvic mass, and innumerable liver nodules. Immediate interpretation of the needle core biopsies of the pelvic mass and liver lesions initially favored a poorly differentiated adenocarcinoma. Unusual positive immunohistochemical stains for CD30 and CK7 ultimately led the investigation toward a tumor of mesenchymal origin. Further, immunohistochemical evaluation demonstrated positive CD31 and Factor VIII staining and established the final diagnosis of epithelioid angiosarcoma. The tumor cells were negative for CD34, CK20, alpha‐fetoprotein, placental‐like alkaline phosphatase, hepatocyte paraffin 1, polyclonal carcinoembryonic antigen, CD10, CA‐125, prostate‐specific antigen, and prostatic acid phosphatase. This case is reported to illustrate the importance of considering the diagnosis of epithelioid angiosarcoma when encountering an “epithelioid” neoplasm particularly with unusual immunoreactivity for CK7 and CD30.

Comparison of the clinical significance of the Papanicolaou test interpretations LSIL cannot rule out HSIL and ASC‐H
Authors: Difurio Megan J. , Mailhiot Thomas , Sundborg Michael J. , Nauschuetz Karen K.
Published: October 2009

Despite the two‐tiered classification of dysplasia in The Bethesda System (TBS), rare cases fall into the category squamous intraepithelial lesion (SIL) of indeterminate grade. These Pap tests are often interpreted as “LSIL/ASC‐H” or “LSIL” with a comment indicating the presence of cells with features approaching HSIL. Patients with LSIL/ASC‐H have a significant risk of CIN 2 or worse (29–61.5%) on follow‐up cervical biopsies, similar to the risk of CIN 2 or worse in patients with ASC‐H Pap tests (24–68%). The purpose of this study was to compare patients with ASC‐H and LSIL/ASC‐H Pap tests. Women with LSIL/ASC‐H had a slightly lower incidence of CIN 2 or worse (PPV = 35.6%, 95% CI: 29.8–41.4%) on follow‐up cervical biopsy than the control ASC‐H group (PPV = 40.2%, 95% CI: 31.9–56.3%); this difference was not statistically significant. The difference in the distribution of the biopsy results between the two groups was statistically significant (P < 0.001). The current guidelines for the management of cervical cytologic abnormalities from the American Society for Colposcopy and Cervical Pathology (ASCCP) advocate similar treatment algorithms for both LSIL and ASC‐H. The main difference is the option of cytologic follow‐up or HPV testing for certain “special populations,” as an alternative to colposcopy, for LSIL Pap test results. Based on our results, we recommend (1)LSIL/ASC‐H to be added to TBS classification and (2) Pap test cases of LSIL/ASC‐H may need to be clinically followed in a manner similar to ASC‐H, i.e., colposcopy for all patients.
