Antimicrobial resistance of Escherichia coli strains isolated from urine of women with cystitis or pyelonephritis and feces of dogs and healthy humans
Authors: Sannes Mark R. , Kuskowski Michael A. , Johnson James R. 
Published: July 2006

Abstract

Objective—To assess the prevalence and patterns of
antimicrobial resistance among Escherichia coli
strains isolated from the urine of women with cystitis
or pyelonephritis and from fecal samples from dogs
and healthy humans.

Design—Cross-sectional survey.
Sample Population—Escherichia coli isolates from
82 women with cystitis, 170 women with pyelonephritis,
45 dogs, and 76 healthy human volunteers.

Procedure—Susceptibility to 12 antimicrobial agents
was determined by means of disk diffusion testing as
specified by the NCCLS.

Results—Overall, the 4 most common antimicrobial
resistance patterns were resistance to ampicillin, sulfisoxazole,
trimethoprim, and trimethoprim-sulfamethoxazole
(n = 45 [12% of all isolates]); ampicillin
alone (33 [9%]); ampicillin and sulfisoxazole (29 [8%]);
and sulfisoxazole alone (14 [4%]). None of the isolates
were resistant to ceftazidime, ciprofloxacin, nitrofurantoin,
or piperacillin-tazobactam. Resistance was
significantly more common and extensive among isolates
from women with cystitis or pyelonephritis than
among isolates from healthy humans or dogs.
Resistance was least common among isolates from
dogs. The only resistance phenotype that was more
common among canine isolates than human isolates
was resistance to sulfisoxazole alone.

Conclusions and Clinical Relevance—Results suggest
that dogs are unlikely to be an important external reservoir
of antimicrobial-resistant E coli strains causing infections
in humans. On the contrary, the data suggest that dogs
conceivably could acquire resistant E coli strains from
humans. ( J Am Vet Med Assoc 2004;225:368–373)
Survival time, lifespan, and quality of life in dogs with idiopathic Fanconi syndrome
Authors: Yearley Jennifer H. , Hancock Dale D. , Mealey Katrina L. 
Published: July 2006

AbstractObjective—To evaluate survival time of dogs with idiopathic Fanconi syndrome.Design—Case series.Animals—60 dogs with idiopathic Fanconi syndrome.Procedure—Data were collected by means of questionnaires distributed to owners and veterinarians of dogs with idiopathic Fanconi syndrome and by examination of medical records when accessible. Questionnaires and records were reviewed for criteria used in diagnosis, treatments administered, survival time, and subjective owner perceptions regarding their dogs' general condition.Results—58 of the dogs were Basenjis. Fifty-seven dogs (95%) were reportedly managed by use of a single therapeutic regimen. Median survival time after diagnosis of Fanconi syndrome was 5.25 years; median estimated lifespan was calculated to be between 11.3 and 12.1 years. Owners of 28 of 29 (97%) dogs still alive at the time of the study subjectively assessed their dogs' general condition as good to excellent. Seizures or other neurologic dysfunction was reported for 11 dogs.Conclusions and Clinical Relevance—Results suggest that expected lifespan for dogs with idiopathic Fanconi syndrome was not substantially reduced, compared with expected lifespan for unaffected dogs, and that affected dogs generally had a good to excellent quality of life, as subjectively assessed by their owners. What effect the treatment regimen had on survival time or lifespan could not be determined, given the small number of dogs managed with other methods. The high percentage of dogs with neurologic abnormalities was a concern, but whether this was related to Fanconi syndrome or represented a breed-related predisposition to neurologic disease could not be determined.

Congenital transmission of Trichinella spiralis in experimentally infected mice
Authors: Cui J. , Wang Z. , Han H. 
Published: July 2006

Abstract
Congenital transmission of T. spiralis infectio in BALB/c mice was studied. Pregnant mice were each infected with 300 larvae 5, 7, 15 and 17 days after fertilization. Newborn mice were examined by artificial digestion of muscles. Out of 6 offspring born to the mother-mouse infected 7 days after fertilization, two offspring were found to be infected, 7 and 24 larvae were recovered respectively. Other 7 female mice were first infected with T. spiralis larvae and then gestated, only the offspring born to the mother-mice fertilized 8 and 22 days after infection were found to be infected with a larval burden ranging from 1–3 larvae per animal. All of the larvae recovered from the offspring were the non-encapsulated larvae. The cross-fostering in which one-day old young born to healthy mother-mice were nursed by infected mothers for 21 days, showed that no young were found to be infected. These findings showed that tansplacental transmission of T. spiralis could occur in mice, if the female were infected during mid-pregnancy or fertilized in 1 month after infection (e.g., infected in one month before fertilization). The larvae transmitted from maternal-to-neonatal mice may be migrating. Transmammary transmission of T. spiralis was not observed.

The activity of selected hydrolases of adult female Ascaris suum, Goeze 1782
Authors: Dziekońska-Rynko J. 
Published: July 2006

Abstract
The activity of hydrolases was measured in the perienteric fluid, muscles and three sections of the intestine of female Ascaris suum. In none of the examined samples was the activity of lipase and α-galactosidase detected. The activity of hydrolases in anterior, middle and posterior sections of the A. suum intestine was similar. The high activity of the following glucosidases: β-galactosidase (lactase), N-acetyl-β glucosaminidase and α-fucosidase, was detected in the contents and extracts from the intestinal wall, apart from the activity of those found in earlier studies. In perienteric fluid and in extracts from muscles, a high activity of β-glucuronidase and β-glucosidase was detected; such activity was not found in the intestine.

Published: July 2006

Abstract
Wild boars (Sus scrofa) can play a significant role in circulation and maintenance of certain parasites in the environment. The aim of this study was to determine the seroprevalence of trichinellosis, toxocarosis and ascariosis in wild boars hunted in the Slovak Republic in 2003 and 2004. Anti-Trichinella antibodies were detected in 1.3 % out of 1035 wild boars investigated. No significant differences were observed regarding the positivity of wild boars according to age and sex in both years. The examination of 1173 wild boars for anti-Toxocara antibodies revealed 7.2 % seropositive individuals. Anti-Ascaris antibodies were detected in 6.1 % out of 411 animals examined. Both, anti-Trichinella and anti-Toxocara antibodies were determined in 0.6 % cases. Presence of anti-Trichinella and anti-Ascaris antibodies was recorded in 0.8 % animals. Concurrent infection caused with Toxocara and Ascaris was observed in 1.5 % individuals. This study concentrates on the role of wild boars in circulation and on the maintenance of trichinellosis, toxocarosis and ascariosis in the Slovak Republic.
Enhancement of Modulus, Strength, and Toughness in Poly(methyl methacrylate)‐Based Composites by the Incorporation of Poly(methyl methacrylate)‐Functionalized Nanotubes

Published: July 2006

AbstractPoly(methyl methacrylate) (PMMA)‐functionalized multiwalled carbon nanotubes are prepared by in situ polymerization. Infrared absorbance studies reveal covalent bonding between polymer strands and the nanotubes. These treated nanotubes are blended with pure PMMA in solution before drop‐casting to form composite films. Increases in Young's modulus, breaking strength, ultimate tensile strength, and toughness of ×1.9, ×4.7, ×4.6, and ×13.7, respectively, are observed on the addition of less than 0.5 wt % of nanotubes. Effective reinforcement is only observed up to a nanotube content of approximately 0.1 vol %. Above this volume fraction, all mechanical parameters tend to fall off, probably due to nanotube aggregation. In addition, scanning electron microscopy (SEM) studies of composite fracture surfaces show a polymer layer coating the nanotubes after film breakage. The fact that the polymer and not the interface fails suggests that functionalization results in an extremely high polymer/nanotube interfacial shear strength.
A Simple Hydrothermal Method for the Large‐Scale Synthesis of Single‐Crystal Potassium Tungsten Bronze Nanowires

Published: July 2006

AbstractThe large‐scale synthesis of single‐crystal KxWO3 tungsten bronze nanowires has been successfully realized by a hydrothermal method under mild conditions. Uniform K0.33WO3 nanowires with diameters of 5–25 nm and lengths of up to several micrometers are obtained. It is found that the morphology and crystallographic forms of the final products are strongly dependent on the sulfate and citric acid, which may act as structure‐directing and soft‐reducing agent, respectively. Some other influential factors on the growth of tungsten bronze nanowires, such as temperature and reaction time, are also discussed. It is worth noting that other alkali metal tungsten bronzes such as (NH4)xWO3, RbxWO3, and CsxWO3 could also be selectively synthesized by a similar route. Thus, this novel and efficient method could provide a potential mild route to selectively synthesize various tungsten bronze on‐dimensional nanomaterials.
Phosphabarrelenes as Ligands in Rhodium‐Catalyzed Hydroformylation of Internal Alkenes Essentially Free of Alkene Isomerization
Authors: Fuchs Evelyn , Keller Manfred , Breit Bernhard 
Published: July 2006

AbstractDespite significant research efforts in the past, one of the remaining problems to be solved in industrially important hydroformylation is the chemoselective low‐pressure hydroformylation of internal alkenes. We report here on a new class of phosphabarrelene/rhodium catalysts 2 that display very high activity towards hydroformylation of internal alkenes with an unusually low tendency towards alkene isomerization. Preparation of new phosphabarrelene ligands, studies of their coordination properties, as well as results obtained in the rhodium‐catalyzed hydroformylation of cyclic and acyclic internal alkenes are reported.

Published: July 2006

AbstractThe new layered oxonitridosilicate EuSi2O2N2 has been synthesized in a radio‐frequency furnace at temperatures of about 1400 °C starting from europium(III) oxide (Eu2O3) and silicon diimide (Si(NH)2). The structure of the yellow material has been determined by single‐crystal X‐ray diffraction analysis (space group P1 (no. 1), a=709.5(1), b=724.6(1), c=725.6(1) pm, α=88.69(2), β=84.77(2), γ=75.84(2)°,V=360.19(9)×106 pm3, Z=4, R1=0.0631, 4551 independent reflections, 175 parameters). Its anionic Si2O2N22− layers consist of corner‐sharing SiON3 tetrahedra with threefold connecting nitrogen and terminal oxygen atoms. High‐resolution transmission electron micrographs indicate both ordered and disordered crystallites as well as twinning. Magnetic susceptibility measurements of EuSi2O2N2 exhibit Curie–Weiss behavior above 20 K with an effective magnetic moment of 7.80(5) μB Eu−1, indicating divalent europium. Antiferromagnetic ordering is detected at 4.5(2) K. EuSi2O2N2 shows a field‐induced transition with a critical field of 0.50(5) T. The four crystallographically different europium sites cannot be distinguished by 151Eu Mössbauer spectroscopy. The room‐temperature spectrum is fitted by one signal at an isomer shift of δ=−12.3(1) mm s−1 subject to quadrupole splitting of ΔEQ=−2.3(1) mm s−1 and an asymmetry parameter of 0.46(3). Luminescence measurements show a narrow emission band with regard to the four crystallographic europium sites with an emission maximum at λ=575 nm.

Published: July 2006

AbstractTreatment of di‐tert‐butylthioketene S‐oxide (5 a) with Lawesson reagent at room temperature resulted in the formation of 3,3‐di‐tert‐butylthiirane‐2‐thione (4 a) in high yield. The oxidation of 4 a with mCPBA (mCPBA=m‐chloroperbenzioc acid) gave 3,3‐di‐tert‐butylthiirane‐2‐thione S‐oxide (6) almost quantitatively. The reactions of 4 a with dimethyl acetylenedicarboxylate (DMAD) and benzyne afforded dimethyl 2‐(2,2,4,4‐tetramethylpentan‐3‐ylidene)‐1,3‐dithiole‐4,5‐dicarboxylate (13) and 2‐(2,2,4,4‐tetramethylpentan‐3‐ylidene)benzo[d][1,3]dithiole (15), respectively, in high yields, suggesting that 4 a is an excellent 1,3‐dipole. The reaction of 4 a with ethylenebis(triphenylphosphine)platinum (16) gave dithiolato‐platinum complex (22) in high yield. The structure of 22 was determined by X‐ray crystallographic analysis.
Intramolecular Hetero‐Michael Addition of β‐Hydroxyenones for the Preparation of Highly Substituted Tetrahydropyranones
Authors: Reiter Maud , Turner Hazel , Gouverneur Véronique 
Published: July 2006

AbstractStructurally diverse β‐hydroxyenones are shown to undergo nonoxidative 6‐endo‐trig ring closure to form highly substituted tetrahydropyranones. Amberlyst‐15, Al(ClO4)3⋅9 H2O and [Pd(MeCN)4](BF4)2 were found to be suitable catalysts for these intramolecular conjugate additions, preventing side reactions, such as dehydration or retroaldolisation. The use of [Pd(MeCN)4](BF4)2 is particularly effective, as this palladium‐mediated reaction is under kinetic control and generates tri‐ and tetrasubstituted tetrahydropyranones with high levels of diastereocontrol. In the presence of the Lewis acid Al(ClO4)3⋅9 H2O, the reaction proceeded with a similar level of diastereocontrol; however, in contrast to [Pd(MeCN)4](BF4)2, this catalyst can promote enolisation. The palladium‐mediated reaction was also found to be compatible with an enantioenriched β‐hydroxyenone substrate, giving no loss of enantiopurity upon ring closure. The most distinctive synthetic development to emerge from this new chemistry is the possibility to access tri‐ and tetrasubstituted 2,6‐anti‐tetrahydropyranones from anti‐aldol precursors. These compounds are particularly difficult to access by using alternative methodologies. Two modes of activation were envisaged for the ring closure, involving metal coordination to either the CC or CO functional groups. Experimental results suggest that CO coordination was the preferred mode of activation for reactions performed in the presence of Al(ClO4)3⋅9 H2O or [Pd(MeCN)4](BF4)2.
