Hormonal acceleration of song development illuminates motor control mechanism in canaries
Authors: Alliende Jorge A. , Méndez Jorge M. , Goller Franz , Mindlin Gabriel B. 
Published: September 2010

AbstractIn songbirds, the ontogeny of singing behavior shows strong parallels with human speech learning. As in humans, development of learned vocal behavior requires exposure to an acoustic model of species‐typical vocalizations, and, subsequently, a sensorimotor practice period after which the vocalization is produced in a stereotyped manner. This requires mastering motor instructions driving the vocal organ and the respiratory system. Recently, it was shown that, in the case of canaries (Serinus canaria), the diverse syllables, constituting the song, are generated with air sac pressure patterns with characteristic shapes, remarkably, those belonging to a very specific mathematical family. Here, we treated juvenile canaries with testosterone at the onset of the sensorimotor practice period. This hormone exposure accelerated the development of song into stereotyped adultlike song. After 20 days of testosterone treatment, subsyringeal air sac pressure patterns of song resembled those produced by adults, while those of untreated control birds of the same age did not. Detailed temporal structure and modulation patterns emerged rapidly with testosterone treatment, and all previously identified categories of adult song were observed. This research shows that the known effect of testosterone on the neural circuits gives rise to the stereotyped categories of respiratory motor gestures. Extensive practice of these motor patterns during the sensorimotor phase is not required for their expression. © 2010 Wiley Periodicals, Inc. Develop Neurobiol 70: 943–960, 2010
Development and validation of fixed‐time method for the determination of isoxsuprine hydrochloride in commercial dosages forms
Authors: Rahman Nafisur , Afaq Nasheed 
Published: September 2010

AbstractThe main aim of this work was to develop a kinetic spectrophotometric method for the quantitative analysis of isoxsuprine hydrochloride in commercial tablets. The method is based on the reaction of isoxsuprine hydrochloride (ISx) with hydroxylamine hydrochloride and ammonium cerium (IV) nitrate in sulphuric acid medium at room temperature which resulted in the formation of yellow‐coloured product peaking at 380 nm. The reaction is followed spectrophotometrically by measuring the absorbance as a function of time. Fixed time method (ΔA = A4–A2, where A2 and A4 refer to absorbance measurements taken at 2 and 4 min, respectively) was adopted for constructing the calibration curve which was found to be linear over the concentration range of 30–80 µgmL−1 with molar absorptivity of 5.95 × 103 L mol−1 cm−1. The method has been applied successfully to the determination of isoxsuprine hydrochloride in tablets. Statistical comparison (point and interval hypothesis tests) of the results showed that there is no significant difference between the proposed method and reference method.

Simultaneous spectrophotometric determination of chlordiazepoxide and clidinium using multivariate calibration techniques
Authors: Khoshayand Mohammad Reza , Abdollahi Hamid , Moeini Ali , Shamsaie Ali , Ghaffari Alireza , Abbasian Sepideh 
Published: September 2010

AbstractThree multivariate modelling approaches including partial least squares regression (PLS), genetic algorithm‐partial least squares regression (GA‐PLS), and principal components‐artificial neural network (PC‐ANN) analysis were investigated for their application to the simultaneous determination of chlordiazepoxide and clidinium levels in pharmaceuticals. A set of synthetic mixtures of drugs in ethanol and 0.1 M HCL was made, and the prediction abilities of the aforementioned methods were examined using RSE% (relative standard error of the prediction). The PLS and PC‐ANN methods were found to be comparable, and GA‐PLS produced slightly better results. The predictive models that we built were successfully applied to simultaneously determine the levels of chlordiazepoxide and clidinium in coated tablets. Copyright © 2010 John Wiley & Sons, Ltd.
Synthesis and Molecular Structure of Symmetrical 1,8‐Diarylnaphthalenes
Authors: Pieters Grégory , Terrasson Vincent , Gaucher Anne , Prim Damien , Marrot Jerôme 
Published: September 2010

AbstractThe synthesis of substituted 1,8‐diarylnaphthalenes is reported. A bis‐Suzuki coupling strategy starting from 1,8‐dibromonaphthalene provides a useful and general route to the 1,8‐diarylnaphthalene scaffold. In this context, N‐heterocyclic benzhydrylamine ligands, in combination with PdCl2, were found to form especially efficient catalytic systems. The syn/anti ratios were determined in solution from their 1H NMR spectra. Analysis of the molecular structure in the solid state for six new targets focused on deformation of the naphthalene core. The observed lack of planarity occurs as a result of several parameters, such as the nature and number of substituents, the substitution pattern as well as steric congestion and π‐stacking between cofacial rings.
Microwave‐Assisted Synthesis of Polysubstituted 4‐Quinolones from Deprotonated α‐Aminonitriles
Authors: Romek Alexandra , Opatz Till 
Published: September 2010

AbstractThe α‐alkylation of deprotonated N‐aryl‐α‐aminonitriles with α‐bromoesters furnishes intermediates that can be cyclized to 4‐quinolones upon microwave irradiation. Alternatively, base‐induced dehydrocyanation of the alkylation products furnishes enaminoesters, which can, for example, be converted into quinoline‐3‐carboxylates.
Concentrations of perfluorinated compounds in human blood from twelve cities in China
Authors: Pan Yuanyuan , Shi Yali , Wang Jieming , Cai Yaqi , Wu Yongning 
Published: September 2010

Abstract
We detected nine perfluorinated compounds (PFCs) in 233 human whole-blood samples collected from 12 cities (from 12 provinces and districts) in China. Perfluorinated compounds could be detected in all blood samples, with perfluorooctane sulfonate (C8, PFOS) as the most prominent PFC. Mean PFOS concentrations were measured at 3.06 to 34.0 µg/L, accounting for the majority of the total perfluorinated compounds (ΣPFCs) (54–87%) in blood samples, except those from Kunming. Perfluorooctane sulfonate and perfluorohexane sulfonate (C6, PFHxS) concentrations were positively correlated in blood samples (p &lt; 0.01). Significant relations among perfluorooctanoate (C8, PFOA), perfluorononanoic acid (C9, PFNA), perfluorodecanoic acid (C10, PFDA), and perfluoroundecanoic acid (C11, PFUnDA) (p &lt; 0.05) were also observed in the present study, indicating that they may come from a similar exposure pathway in China. In general, gender-related differences were found for PFHxS and ΣPFCs concentrations, which were significantly higher in males than in females (p &lt; 0.05). In the 20- to 29-year age group, gender influence was also found for PFHxS and PFOS concentrations. The mean blood concentration of PFOS (10.6 µg/L) in the present study was comparable with results from other countries, while PFOA and PFHxS (1.39 µg/L and 0.57 µg/L, respectively) were often lower. This can probably be attributed to a different exposure pathway of the general population in China as compared to other countries. Environ. Toxicol. Chem. 2010;29:2695–2701. © 2010 SETAC
Modeling and predicting competitive sorption of organic compounds in soil
Authors: Faria Isabel R. , Young Thomas M. 
Published: September 2010

Abstract
Binary systems consisting of 1,2-dichlorobenzene (12DCB) + competitor were investigated over a range of concentrations of competitor in three natural sorbents with distinct characteristics. Two models, the ideal adsorbed solution theory (IAST) and the potential theory (Polanyi-based multisolute model), widely used in the prediction of multisolute sorption equilibrium from single-solute data, were used to simulate competitive sorption in our systems. The goal was to determine which multisolute model best represented the experimentally obtained multisolute data in natural sorbents of varied properties. Results suggested that for the sorbents and sorbates studied, the IAST model provided much better results. On average, the IAST model provided lower errors (23%) than the potential model (45%). The effect of competitor structure on the degree of competition was also investigated to identify any relationships between competition and structure using molecular descriptors. The competitors chlorobenzene, naphthalene, 1,4-dichlorobenzene, 1,2,4-trichlorobenzene all showed very similar degrees of competition, while benzene, phenanthrene, and pyrene were the least effective competitors toward 12DCB across all sorbents. Different sorption sites or sorption mechanisms might be involved in the sorption of these molecules leading to a lack of competitive behavior. A significant relationship between competitor structure and the degree of competition was observed at environmentally relevant sorbed competitor concentrations for the soil containing the highest fraction of hard carbon (Forbes soil).

Abstract
The University of Michigan Dioxin Exposure Study was undertaken to address concerns that the industrial discharge of dioxin-like compounds in the Midland, Michigan, USA area had resulted in the contamination of soil and vegetation in the Tittabawassee River floodplain and downwind of the incinerator in the City of Midland. The study included the analysis of 597 vegetation samples, predominantly grass and weeds, from residential properties selected through a multistage probabilistic sample design in the Midland area, and in Jackson and Calhoun Counties (Michigan), as a background comparison, for 29 polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs), and polychlorinated biphenyls (PCBs). The mean toxic equivalent (TEQ) of the house perimeter vegetation samples ranged from 4.2 to 377 pg/g. The ratio of TEQs (vegetation to soil) was about 0.3, with a maximum of 3.5. Based on a calculation of the similarity of the congener patterns between the soil and the vegetation, it appeared that the source of the contamination on the vegetation was the surrounding soil. This conclusion was supported by linear regression analysis, which showed that the largest contributor to the R2 for the outcome variable of log10 of the vegetation concentration was log10 of the surrounding soil concentration. Models of vegetation contamination usually focus on atmospheric deposition and partitioning. The results obtained here suggest that the deposition of soil particles onto vegetation is a significant route of contamination for residential herbage. Thus, the inclusion of deposition of soil particles onto vegetation is critical to the accurate modeling of contamination residential herbage in communities impacted by historic industrial discharges of persistent organic compounds.
