Resynchronization with Left Ventricle Lead Placement Through the Foramen Ovale
Authors: D'Ivernois Christophe , Blanc Patrick 
Published: April 2009

AbstractLeft ventricle (LV) lead placement in a coronary sinus branch for cardiac resynchronization therapy may fail because of anatomical variants, phrenic nerve stimulation, and/or lead instability. We report a case of successful resynchronization from a lead inserted from the left subclavian vein and positioned through a patent foramen ovale (PFO). In conclusion, endocardial LV lead insertion through a PFO enables effective resynchronization delivery without the risks associated with a thoracotomy or atrial transseptal puncture.

Trout Farm Effluent Effects on Water Sediment Quality and Benthos
Authors: Kırkağaç Mine Uzbilek , Pulatsu Serap , Topcu Akasya 
Published: April 2009

AbstractSeveral water (dissolved oxygen, pH, ammonia‐nitrogen, nitrite‐nitrogen, nitrate‐nitrogen, total phosphorus and orthophosphate) and sediment (organic matter, total nitrogen, organic carbon and phosphorus) quality parameters, as well as benthic macroinvertebrate communities were investigated monthly between May 2007 and November 2007 at a rainbow trout farm located on one of the sources of the Sakarya River in Central Anatolia. Water and sediment samples were collected from three stations, i. e., the inlet of the farm, which was a karst spring‐originated pond, the outlet of the farm, and a location 200 m from the outlet of the trout farm, which has a capacity of 30 t annually. These water quality parameters were compared to the acceptable effluent limits proposed for trout farming in different countries. Ammonia‐nitrogen, total phosphorus and orthophosphate were found to be higher than the acceptable effluent limits during the study period. Sediment quality parameters were also found to be higher than those at the inlet of the farm. The benthic macroinvertebrate community consisted of only Gastropoda (Limnaedae, Planorbidae, Neritidae and Pleuroceridae). Almost identical organism groups were observed at the three stations, and the highest abundance was found at the outlet of the farm during the study. Finally, as an indicator of damage to the environment, the biodiversity indices were generally measured at levels below 1 in all stations.
Evaluation of Remediation Effects of the Auto‐Refining Processes of the Lavin River
Authors: Kokya Taher Ahmadzadeh , Kokya Bahman Ahmadzadeh , Farhadi Khalil 
Published: April 2009

AbstractThe dependence of the auto‐refining process of the Lavin River, Iran, on the types and the quality of chemicals and organic compounds discharged into the river as the wastewater generated by sugar beet industries located nearby, was investigated. For the purposes of this study, sampling was performed utilizing a design‐based static stationary sampling pattern. Several study stations were selected around the waste discharge location in order to perform sampling and field investigations during three sampling campaigns within two years. Numerous analytical procedures were performed on the samples for water quality assessment. In addition, a recently developed dispersive liquid‐liquid microextraction method was employed as a more sensitive sample preparation method for the instrumental chemical analysis, in order to enhance the limits of detection of the trace biocide residues. The evaluation and validation of the data acquired from the field observations, sampling, and river water quality assessment was performed using statistical methods. The obtained results showed that the auto‐refining process is an exclusive river remediation factor that indicates a variety of auto‐refining capacities for various chemical, physical and biological contaminating parameters affecting the water quality of the Lavin River.

Published: April 2009

AbstractThe removal of Congo red dye from an aqueous solution using perlite, a volcanic siliceous rock, as a low cost adsorbent was studied. Adsorption experiments were carried out as batch studies at different adsorbent dose, pH, temperature and initial dye concentration. The dye adsorption equilibrium was rapidly attained after 40 min of contact time. The adsorbent was characterized by Fourier Transform Infrared spectroscopy (FTIR), X‐ray Diffraction (XRD) and Scanning Electron Microscopy (SEM). Langmuir and Freundlich isotherms were studied for the adsorption data over a concentration range of 20 to 100 mg/L. The thermodynamic parameters such as entropy of adsorption (ΔS0), enthalpy of adsorption (ΔH0) and Gibbs free energy of adsorption (ΔG0) were obtained and analyzed. Kinetic studies showed that the adsorption process obeyed the pseudo first order kinetic model. The dimensionless separation factors (RL) showed that perlite could be used to remove Congo red from an aqueous solution.
Synthesis of Microporous Cationic Hydrogel of Hydroxypropyl Cellulose (HPC) and its Application on Anionic Dye Removal
Authors: Yan Lifeng , Shuai Qi , Gong Xiaoli , Gu Qing , Yu Hanqing 
Published: April 2009

AbstractHydroxypropyl cellulose has been crosslinked by epichlorohydrin (EPI) and ammonia in sodium hydroxide aqueous solution. A temperature induced phase separation (TIPS) process was applied to synthesize a microporous crosslinked HPC hydrogel and was confirmed by SEM studies. The cationic HPC hydrogel showed an excellent ability to adsorb anionic dye AO7, and the maximum adsorption capacity at room temperature was found to be 2478 (g/kg) at pH 3.96. Both Langmuir and Freundlich adsorption models were applied to describe the equilibrium isotherms, and the Langmuir model agreed well with the experimental data (R2 > 0.99). Kinetics of the adsorption were tested and the data agreed well with the pseudo‐second‐order kinetic model. The strong electrostatic interaction between the quaternary ammonium and dye anions could be the main driving force adsorption. The effects of pH and temperature on the adsorption of the dye have also been investigated and discussed.
Studies on a Mg‐Al‐Zn Alloy as an Anode for the Removal of Fluoride from Drinking Water in an Electrocoagulation Process
Authors: Vasudevan Subramanyan , Lakshmi Jothinathan , Sozhan Ganapathy 
Published: April 2009

AbstractThe present study provides an electrochemical coagulation process for the removal of fluoride from drinking water using a Mg‐Al‐Zn alloy, magnesium, aluminum and mild steel as anodes and stainless steel as cathode. Various parameters which may affect the removal efficiency of fluoride from water, such as pH, concentration of fluoride, current density, temperature and co‐existing ions were studied. Electrochemical coagulation was carried out for 30 min at an initial fluoride concentration of 5.0 mg/L and this was reduced to 0.2 mg/L. A maximum removal efficiency of 96% was achieved with a magnesium alloy as anode and stainless steel as cathode at a current density of 0.2 A/dm2 and a pH of 7.0.
Pharmaceuticals, Personal Care Products and Endocrine Disrupting Agents in the Environment – A Review
Authors: Caliman Florentina Anca , Gavrilescu Maria 
Published: April 2009

AbstractIn the last few years, concerns about the environmental fate and behavior of synthetic organic chemicals for hygienic use detected in waters have increased. Several of these compounds are used intensively, in large volumes, are persistent, bioactive and exhibit bioaccumulation and endocrine disrupting activity. Some pharmaceuticals, including analgesics, antibiotics, antiepilieptics, β‐blockers, blood‐lipid regulators and contraceptives also have the potential to determine various physiologic responses in aquatic organisms. Other compounds (natural hormones and several industrial and household chemicals) able to affect organisms in receiving waters are also endocrine disrupting agents. A lack of information still exists regarding the potential impact associated with the occurrence, fate and ecotoxicological effects of endocrine disruptors, including pharmaceuticals and personal care compounds in the environment since few compounds were inventoried or regulated worldwide. In some cases, there are no legal requirements to assess the impact of long‐term exposure to low concentration of these chemicals. This may be because important classes of these compounds have not been studied in detail up to now due to the non‐availability of suitable instrumental techniques or analytical standards for low concentration levels. Recently, the appearance of sophisticated tests for monitoring environmental contamination has revealed the presence of these types of contaminants at lower levels, down to nanograms per liter. This constitutes an important tool in the development of guidelines to monitor and/or update environmental compliance reports. The current survey aims to combine information from the literature on the environmental occurrence, fate and effects of personal care products and endocrine disrupting agents on the environment; as well as on the treatment options for their removal from wastewaters.
The dynamin related protein Dnm1 fragments mitochondria in a microtubule‐dependent manner during the fission yeast cell cycle
Authors: Jourdain Isabelle , Gachet Yannick , Hyams Jeremy S. 
Published: April 2009

AbstractMitochondria are dynamic organelles that undergo cycles of fission and fusion. In the fission yeast, Schizosaccharomyces pombe, mitochondria align with microtubules and mitochondrial integrity is dependent upon an intact microtubule cytoskeleton. Here we show that mitochondria re‐organize during the cell cycle and that this process is both dynamin‐ and microtubule‐dependent. Microtubule depolymerization results in mitochondrial fragmentation but only when the dynamin‐related protein Dnm1 is present. Mitochondrial fusion is, on the other hand, microtubule‐independent. dnm1Δ cells, besides showing extensively fused mitochondria, are specifically resistant to anti‐microtubule drugs. Dnm1‐YFP localizes to foci at sites of mitochondrial severing which occupy the interface between adjacent nucleoids, suggesting the existence of defined mitochondrial “territories,” each of which contains a nucleoid. Such territories are lost in dnm1Δ in which nucleoids become aggregated. Mitochondrial ends exhibit motile behavior, extending towards and retracting from the cell poles, independently of the cytoskeleton. We conclude that: (a) mitochondria are organized by microtubules in fission yeast but are not moved by them; (b) Dnm1 mediates mitochondrial fission during interphasic growth and at cell division; (c) the interaction between microtubules and mitochondria, either directly or indirectly via Dnm1, not only modifies the disposition of mitochondria it also modifies the behavior of microtubules.

N‐WASP and cortactin are involved in invadopodium‐dependent chemotaxis to EGF in breast tumor cells

Published: April 2009

AbstractMetastatic mammary carcinoma cells, which have previously been observed to form mature, matrix degrading invadopodia on a thick ECM matrix, are able to form invadopodia with similar characteristics on glass without previously applied matrix. They form in response to epidermal growth factor (EGF), and contain the usual invadopodium core proteins N‐WASP, Arp2/3, cortactin, cofilin, and F‐actin. The study of invadopodia on glass allows for higher resolution analysis including the use of total internal reflection microscopy and analysis of their relationship to other cell motility events, in particular, lamellipodium extension and chemotaxis toward an EGF gradient. Invadopodium formation on glass requires N‐WASP and cortactin but not microtubules. In a gradient of EGF more invadopodia form on the side of the cells facing the source of EGF. In addition, depletion of N‐WASP or cortactin, which blocks invadopodium fromation, inhibits chemotaxis of cells towards EGF. This appears to be a localized defect in chemotaxis since depletion of N‐WASP or cortactin via siRNA had no effect on lamellipodium protrusion or barbed end generation at the lamellipodium's leading edge. Since chemotaxis to EGF by breast tumor cells is involved in metastasis, inhibiting N‐WASP activity in breast tumor cells might prevent metastasis of tumor cells while not affecting chemotaxis‐dependent innate immunity which depends on WASp function in macrophages.

Neutrophils display biphasic relationship between migration and substrate stiffness
Authors: Stroka Kimberly M. , Aranda‐Espinoza Helim 
Published: April 2009

AbstractNeutrophils are one type of migrating cell in the body's innate immune system and are the first line of defense against inflammation or infection. While extensive work exists on the effect of adhesive proteins on neutrophil motility, little is known about how neutrophil motility is affected by the mechanical properties of their physical environment. This study investigated the effects of substrate stiffness on the morphology, random motility coefficient, track speed (v), spreading area, and distribution of turning angles of neutrophils during chemokinesis. Human neutrophils were plated onto polyacrylamide gels of varying stiffness, ranging from 3 to 13 kPa, and coated with the extracellular matrix protein fibronectin, and timelapse images were taken with phase contrast microscopy. Our results show a biphasic behavior between neutrophil motility and substrate stiffness, with the optimum stiffness for motility depending on the concentration of fibronectin on the surface of the gel. On 100 μg/mL fibronectin, the optimum stiffness is 4 kPa (v = 6.9 ± 0.6 μm/min) while on 10 μg/mL fibronectin, the optimum stiffness increases to 7 kPa (v = 4.5 ± 2.0 μm/min). This biphasic behavior most likely arises because neutrophils on soft gels are less adherent, preventing production of traction forces, while neutrophils on stiff gels adhere strongly, resulting in decreased migration. At intermediate stiffness, however, neutrophils can attain optimal motility as a function of extracellular matrix coating. Cell Motil. Cytoskeleton 2009. © 2009 Wiley‐Liss, Inc.
