submitted by goleles 20 minutes ago - Topic: Health
To predict the type and extent of CMR artifacts caused by commonly used pediatric trans-catheter devices at 1.5 T and 3 T as an aid to clinical planning and patient screening. Eleven commonly used interventional, catheter-based devices including stents, septal occluders, vascular plugs and emboli...



Effect of environmental pollution on the proteins, allergenic bands, ontogeny and structure of Avicennia marina (Forsk.) Vierh (Avicenniaceae) pollen grains
submitted by dgdapri 20 minutes ago - Topic: Biology
In Bushehr province of Iran, Avicennia marina trees have grown in Bordekhoon (Mond Protected Area) and Assaluyeh (Marine National Park of Nayband). Contrary to Bordekhoon, Assaluyeh is a petrochemical region with environmental pollution. This study was aimed to studying protein profiles, allergen...

Identification of blaOXA-51-like, blaOXA-58, blaDIM-1, and blaVIM Carbapenemase Genes in Hospital Enterobacteriaceae Isolates from Sierra Leone
submitted by osefroshed 20 minutes ago - Topic: Biology
We describe the results of a molecular epidemiological survey of 15 carbapenemase-encoding genes from a recent collection of clinical isolates from Mercy Hospital in Bo, Sierra Leone. The most salient findings revealed that (i) 60% of the isolates harbored multiple carbapenemase genes; (ii) the b...

Helicobacter cinaedi and Helicobacter fennelliae Transmission in a Hospital from 2008 to 2012
submitted by osefroshed 20 minutes ago - Topic: Biology
Forty-six Helicobacter cinaedi isolates from the same hospital were analyzed by multilocus sequence typing. Most H. cinaedi isolates exhibited clonal complex 9 and were mainly isolated from immunocompromised patients in the same ward. Three Helicobacter fennelliae isolates were obtained from the ...

Asymptomatic Carriage of Sequence Type 398, spa Type t571 Methicillin-Susceptible Staphylococcus aureus in an Urban Jail: a Newly Emerging, Transmissible Pathogenic Strain
submitted by osefroshed 20 minutes ago - Topic: Biology
Sequence type 398 (ST398) Staphylococcus aureus, frequently carried by livestock, has caused severe human infections and often carries transmissible antibiotic resistance genes. Among methicillin-susceptible S. aureus isolates colonizing Dallas County Jail detainees, 13.2% were ST398, spa type t5...



Comparison of Restriction Enzymes for Pulsed-Field Gel Electrophoresis Typing of Moraxella catarrhalis
submitted by osefroshed 20 minutes ago - Topic: Biology
NotI, the most prevalent restriction enzyme used for typing Moraxella catarrhalis, failed to digest genomic DNA from respiratory samples. An improved pulsed-field gel electrophoresis (PFGE) methodology determined SpeI as the best choice for typing this bacterial species, with a good restriction o...

First Report of Nocardia asiatica Olecranon Bursitis in an Immunocompetent Traveler Returning to Austria
submitted by osefroshed 20 minutes ago - Topic: Biology
Nocardia spp. are rarely isolated in extrapulmonary clinical specimens. We describe the first case of olecranon bursitis caused by Nocardia asiatica. The patient, a traveler returning from Thailand, was successfully treated with linezolid.

Human Cryptosporidiosis Diagnosed in Western Australia: a Mixed Infection with Cryptosporidium meleagridis, the Cryptosporidium Mink Genotype, and an Unknown Cryptosporidium Species
submitted by osefroshed 20 minutes ago - Topic: Biology
This report describes a case of cryptosporidiosis from an immunocompetent patient from Perth, Western Australia, suffering from diarrhea and a spectrum of other symptoms. Molecular identification revealed that this patient was infected with three Cryptosporidium species-Cryptosporidium meleagridi...

Intraventricular Hemorrhage and Multiple Intracranial Cysts Associated with Congenital Cytomegalovirus Infection
submitted by osefroshed 20 minutes ago - Topic: Biology
Intraventricular hemorrhage with congenital cytomegalovirus (CMV) infection is rare and has been reported only in extremely premature infants or in association with thrombocytopenia. We report the first case of a full-term male infant with congenital CMV infection and intraventricular hemorrhage ...

Development and Evaluation of a Calibrator Material for Nucleic Acid-Based Assays for Diagnosing Aspergillosis
submitted by osefroshed 20 minutes ago - Topic: Biology
Twelve laboratories evaluated candidate material for an Aspergillus DNA calibrator. The DNA material was quantified using limiting-dilution analysis; the mean concentration was determined to be 1.73 x 1010 units/ml. The calibrator can be used to standardize aspergillosis diagnostic assays which d...

Polyclonal Outbreak of KPC-3-Producing Enterobacter cloacae at a Single Hospital in Montreal, Quebec, Canada
submitted by osefroshed 20 minutes ago - Topic: Biology
From September 2010 to December 2011, 26 KPC-3-producing Enterobacter cloacae isolates were identified from 16 patients at a single hospital. Analyses revealed the blaKPC gene to be localized on multiple plasmids in a diverse nonclonal E. cloacae genetic background. These findings highlight the p...

Brachyspira Species and Gastroenteritis in Humans
submitted by osefroshed 20 minutes ago - Topic: Biology
Brachyspira species have been implicated as a potential cause of gastroenteritis in humans; this is, however, controversial. In 733 gastroenteritis cases and 464 controls, we found 29 samples positive for Brachyspira species (2.3% of cases and 2.6% of controls; P = 0.77). Brachyspira species were...

Epidemiological and Clinical Complexity of Amoxicillin-Clavulanate-Resistant Escherichia coli
submitted by osefroshed 20 minutes ago - Topic: Biology
Two hundred twelve patients with colonization/infection due to amoxicillin-clavulanate (AMC)-resistant Escherichia coli were studied. OXA-1- and inhibitor-resistant TEM (IRT)-producing strains were associated with urinary tract infections, while OXA-1 producers and chromosomal AmpC hyperproducers...

Evaluation of Simplexa Flu A/B & RSV for Direct Detection of Influenza Viruses (A and B) and Respiratory Syncytial Virus in Patient Clinical Samples
submitted by osefroshed 20 minutes ago - Topic: Biology
We evaluated the performance of the Simplexa Flu A/B & RSV kit on 170 prospective respiratory samples using a modified protocol, supplied by the manufacturer, that eliminates the RNA extraction step. Overall, compared against our laboratory-developed assay, the assay's sensitivity, specificit...

Rapid Molecular Detection of Macrolide Resistance in the Mycobacterium avium Complex: Are We There Yet?
submitted by osefroshed 20 minutes ago - Topic: Biology
Macrolides are an important tool in the treatment of Mycobacterium avium complex infections. Here, we evaluate the use of 23S rRNA gene sequencing for the rapid detection of macrolide resistance. Routine sequencing of the 23S rRNA gene is highly specific for macrolide resistance but lacks in sens...
