Addressing the cost of infractions in the online literature and databases.

Myocardial infarction sometimes appears misspelt as myocardial infraction in the cardiovascular research literature. With accurate citation of literature contributions important to advancing the field and its contributors, in this study we aimed to document the frequency and explore the causes and impact of this error specific to the cardiology literature. Literature databases (PubMed, Scopus, Web of Science, WIPO, Google Scholar, Google) were searched to identify the rate of myocardial infraction errors and found an error rate between 0.

In vitro data support the investigation of vinegar as an antimicrobial agent for PD-associated Pseudomonas exit site infections.

Peritoneal dialysis exit site infections caused by Pseudomonas spp. are difficult to treat and can lead to peritonitis and/or modality failure. Effective alternative or adjunct non-antibiotic antimicrobial agents could improve treatment as well as reduce the use of antibiotics and contribute to a reduction in antibiotic selection pressure and the further development of antibiotic resistance.

Cilostazol blocks pregnancy in naturally cycling swine: An animal model.

Aims: Cilostazol (CLZ) is an FDA approved therapeutic that is indicated for patients with intermittent claudication disease. CLZ is a selective inhibitor for phosphodiesterase 3A (PDE3A); an enzyme that controls oocyte maturation in many mammals including humans. Recently, CLZ has been reported to block pregnancy and oocyte maturation in mice.

Role of selection and inbreeding on the incidence of cutaneous malignant melanoma in Sinclair swine.

This paper reports the quantitative analysis of the historical database of a herd of Sinclair swine affected by cutaneous malignant melanoma. The herd was under partial and non-systematic selection for melanoma susceptibility (animals having at least one tumour during the first 6 weeks of life). Weighted selection differentials for the number of tumours at birth and the number of tumours at 6 weeks were generally positive and between -0.

[RAPD and ISSR analyses of regenerated pea Pisum sativum L. plants].

Long-term pea callus cultures of different genotypes (mutants R-9 and W-1 and cultivar Viola) were used to regenerate plants (generation R0). The regenerants displayed changes both in qualitative and in quantitative traits. The most dramatic morphological alterations and complete sterility were observed in regenerants of the cultivar Viola.

Pediatric laboratory medicine: current challenges and future opportunities.

The practice of pediatric laboratory medicine involves unique challenges related to development, nutrition, growth, and diseases during different periods of infancy, childhood, and adolescence. This article discusses key aspects of pediatric laboratory medicine faced by clinical pathologists, clinical laboratory scientists, and clinicians, including point-of-care testing, preanalytic variables, analytic factors, age-specific reference intervals, esoteric laboratory tests, clinical impact, andfuture opportunities. Although challenging, pediatric laboratory testing offers many opportunities for improved patient care, clinical- and laboratory-based research, and education.

Lipid A mutant Salmonella with suppressed virulence and TNFalpha induction retain tumor-targeting in vivo.

Systemically administered tumor-targeted Salmonella has been developed as an anticancer agent, although its use could be limited by the potential induction of tumor necrosis factor alpha (TNFalpha)-mediated septic shock stimulated by lipid A. Genetic modifications of tumor-targeting Salmonella that alter lipid A and increase safety must, however, retain the useful properties of this bacteria. We report here that disruption of the Salmonella msbB gene reduces TNFalpha induction and increases the LD50 of this pathogenic bacteria by 10,000-fold.

Intravenous catheter aspiration for obtaining basic analytes during intravenous infusion.

The aspiration of blood through a functioning IV line to obtain samples for laboratory analysis was evaluated. Thirty-eight emergency department patients were studied. Each had an 18-gauge IV catheter placed and then received a 100-mL bolus of either normal saline, lactated Ringer's, or 5% dextrose in water.

A DNA probe for the LDL receptor gene is tightly linked to hypercholesterolemia in a pedigree with early coronary disease.

A large, multigenerational family with dominantly inherited hypercholesterolemia was analyzed for genetic linkage between blood levels of low-density lipoprotein (LDL) cholesterol and the locus for the LDL receptor. A genetic marker was identified by restriction fragment length polymorphism (RFLP) in a cloned segment of the LDL receptor gene. We found no exceptions to segregation of the high-LDL cholesterol phenotype with a unique allele at the LDL receptor locus in this pedigree; tight linkage was indicated by a maximum lod score of 7.

Adult reference intervals for 12 chemistry analytes: influences of age and sex.

Blood samples were drawn from 123 "healthy" adults residing in the Salt Lake City, Utah metropolitan area. A sample of adults was identified using a random telephone method and respondents for the study were selected to represent the age and sex distribution of the population. Blood samples were drawn and analyzed for 12 blood analytes.
