Graphene nanonet for biological sensing applications.

Nanotechnology 2013 Sep 21;24(37):375302. Epub 2013 Aug 21.

Department of Physics and Astronomy, Seoul National University, Seoul, Korea.

We report a simple but efficient method to fabricate versatile graphene nanonet (GNN)-devices. In this method, networks of V2O5 nanowires (NWs) were prepared in specific regions of single-layer graphene, and the graphene layer was selectively etched via a reactive ion etching method using the V2O5 NWs as a shadow mask. The process allowed us to prepare large scale patterns of GNN structures which were comprised of continuous networks of graphene nanoribbons (GNRs) with chemical functional groups on their edges.

Transdermal absorption enhancement of papain loaded in elastic niosomes incorporated in gel for scar treatment.

Eur J Pharm Sci 2013 Feb 21;48(3):474-83. Epub 2012 Dec 21.

Faculty of Pharmacy, Chiang Mai University, Chiang Mai 50200, Thailand; Natural Products Research and Development Center (NPRDC), Science and Technology Research Institute (STRI), Chiang Mai University, Chiang Mai 50200, Thailand.

Papain is one of the protease enzymes from Carica papaya latex which is widely used in dermatology for scar treatment. The aim of this study was to compare the penetration of papain from gel formulations containing niosomes and nanospheres loaded with papain. The vesicular sizes of all niosomes and nanospheres in the gel formulations were in the range of 220. Read More

Preschool children with gender normative and gender non-normative peer preferences: psychosocial and environmental correlates.

Arch Sex Behav 2012 Aug 12;41(4):831-47. Epub 2012 Apr 12.

School of Social and Family Dynamics, Arizona State University, Tempe, AZ 85287-3701, USA.

We addressed several issues concerning children who show gender non-normative (GNN) patterns of peer play. First, do young children with GNN peer preferences differ from children with gender normative (GN) peer preferences in problem behaviors? Second, do GNN and GN children differ in sociability and isolation and do they have differential socialization opportunities with externalizing, internalizing, and socially competent peers? We employed a Bayesian approach for classifying children as GNN based on their peer preferences as compared to their peers using a sample of Head Start preschool children from a large Southwestern city (N = 257; 53 % boys; M age = 51 months; 66 % Mexican American). To calculate socialization opportunities, we assessed affiliation to each child in the class and weighted that by each peer's characteristics to determine the exposure that each child had to different kinds of peers.

Rift valley fever virus L protein forms a biologically active oligomer.

J Virol 2009 Dec 7;83(24):12779-89. Epub 2009 Oct 7.

Department of Microbiology and Immunology, University of Texas Medical Branch, Galveston, TX 77555-1019, USA.

Rift Valley fever virus (RVFV) (genus Phlebovirus, family Bunyaviridae) causes mosquito-borne epidemic diseases in humans and livestock. The virus carries three RNA segments, L, M, and S, of negative or ambisense polarity. L protein, an RNA-dependent RNA polymerase, encoded in the L segment, and N protein, encoded in the S segment, exert viral RNA replication and transcription. Read More

DDT, DDE and DDD in human milk from South Africa.

Bull Environ Contam Toxicol 2008 Oct 29;81(4):348-54. Epub 2008 Jul 29.

Tshwane University of Technology, Pretoria, South Africa.

Human breast milk samples (n=30) were collected from mothers within the age range of 19-40 years from Thohoyandou area, South Africa. DDT and its metabolites were extracted from the milk samples using diethyl ether. The crude extracts were subjected to column chromatography. Read More

Genetic neural network modeling of the selective inhibition of the intermediate-conductance Ca2+ -activated K+ channel by some triarylmethanes using topological charge indexes descriptors.

J Comput Aided Mol Des 2005 Nov 23;19(11):771-89. Epub 2005 Dec 23.

Molecular Modeling Group, Center for Biotechnological Studies, Faculty of Agronomy, University of Matanzas, 44740, Matanzas, Cuba.

Selective inhibition of the intermediate-conductance Ca(2+)-activated K(+ )channel (IK (Ca)) by some clotrimazole analogs has been successfully modeled using topological charge indexes (TCI) and genetic neural networks (GNNs). A neural network monitoring scheme evidenced a highly non-linear dependence between the IK (Ca) blocking activity and TCI descriptors. Suitable subsets of descriptors were selected by means of genetic algorithm. Read More

Double cone dystrophy and RPE degeneration in the retina of the zebrafish gnn mutant.

Invest Ophthalmol Vis Sci 2003 Mar;44(3):1287-98

Department for Experimental Ophthalmology, University Eye Hospital, Tübingen, Germany.

Purpose: To characterize morphologic alterations in the retina of the visual mutant zebrafish gantenbein (gnn) and to examine whether these alterations correlate with those present in human hereditary eye diseases.

Methods: The gnn mutant was isolated by behavioral and macroscopic screening. Retinas of gnn zebrafish larvae were examined at different developmental stages from 2 to 9 days postfertilization (dpf) by standard histologic staining techniques and by immunocytochemistry. Read More
