Effect of pre-operative oral paracetamol on gastric residual volume and pH in young children in the context of a 1-hour clear fluid fast: a randomised controlled trial.

High gastric residual volume and low pH are associated with increased mortality following pulmonary aspiration in animal studies. The use of pre-operative oral paracetamol has not been investigated in younger children and infants in the context of a prescriptive 1-h clear fluid fast aimed at reducing the risk of pulmonary aspiration while improving patient experience. Children aged 1 month up to a weight of 25 kg and scheduled for elective surgery were randomly allocated to receive a prescribed 3.

Implementation of a Rapid Phenotypic Susceptibility Platform for Gram-Negative Bloodstream Infections With Paired Antimicrobial Stewardship Intervention: Is the Juice Worth the Squeeze?

Background: Implementation of the Accelerate PhenoTM Gram-negative platform (RDT) paired with antimicrobial stewardship program (ASP) intervention projects to improve time to institutional-preferred antimicrobial therapy (IPT) for Gram-negative bacilli (GNB) bloodstream infections (BSIs). However, few data describe the impact of discrepant RDT results from standard of care (SOC) methods on antimicrobial prescribing.

Methods: A single-center, pre-/post-intervention study of consecutive, nonduplicate blood cultures for adult inpatients with GNB BSI following combined RDT + ASP intervention was performed.

Differential Spatial Gradients of Wheat Streak Mosaic Virus into Winter Wheat from a Central Mite-Virus Source.

The wheat curl mite (WCM), Aceria tosichella Keifer, transmits three potentially devastating viruses to winter wheat. An increased understanding of mite movement and subsequent virus spread through the landscape is necessary to estimate the risk of epidemics by the virus in winter wheat. Owing to the small size of WCMs, their dispersal via wind is hard to monitor; however, the viruses they transmit produce symptoms that can be detected with remote sensing.

Implementation of a pharmacist-driven immunization program designed to improve overall vaccination rates in indigent and uninsured patients.

Objective: To demonstrate the results of a pharmacist-driven immunization program designed to increase overall vaccination rates among the low-income, uninsured patients in a free clinic.

Setting: Cape Fear Clinic, a free clinic located in Wilmington, North Carolina.

Practice Description: Cape Fear Clinic provides medical, pharmacy, mental health, and dental services to adults in 4 eastern North Carolina counties who are uninsured and have incomes of no more than 200% of Federal Poverty Guidelines.

Coptoborus ochromactonus, n. sp. (Coleoptera: Curculionidae: Scolytinae), an emerging pest of cultivated balsa (Malvales: Malvaceae) in Ecuador.

A new species of xyleborine ambrosia beetle has been found to attack balsa, Ochroma pyramidale (Cavanilles ex Lamarck) Urban, in Ecuador. Coptoborus ochromactonus Smith & Cognato is described and its biology is reported. Large-scale surveys were conducted between 2006 and 2009, and observational studies were carried out between 2010 and 2013 in Ecuadorian commercial plantations to determine life history and host preference characteristics.

Degree-day requirements for alfalfa weevil (Coleoptera: Curculionidae) development in eastern Nebraska.

The alfalfa weevil, Hypera postica (Gyllenhal), is a serious, yet sporadic defoliator of alfalfa, Medicago sativa L., in Nebraska. A 2-yr study was conducted in 2005 and 2006 to test for variation in degree-day requirements by location in eastern Nebraska.

E2F-1 gene therapy induces apoptosis and increases chemosensitivity in human pancreatic carcinoma cells.

Pancreatic cancer is often resistant to conventional chemotherapy. In this study, we examined the role of adenovirus-mediated overexpression of E2F-1 in inducing apoptosis and increasing the sensitivity of pancreatic cancer cells to chemotherapeutic agents. MIA PaCa-2 pancreatic head exocrine adenocarcinoma cells (mutant p53) were treated by mock infection or adenoviruses expressing beta-galactosidase or E2F-1 (Ad-E2F-1) alone or in combination with sublethal concentrations of each chemotherapeutic drug.

C-terminal deletion mutant p21(WAF1/CIP1) enhances E2F-1-mediated apoptosis in colon adenocarcinoma cells.

The present study was designed to investigate the efficacy of combination gene therapy using adenoviral vectors expressing gene products shown to possess apoptotic activity: E2F-1 (Ad-E2F-1) and a C-terminal deletion mutant of p21(WAF1/cIP1) (Ad-p21(-PCNA)), on growth inhibition and apoptosis of human colon cancer cells in vitro and in vivo. Marked E2F-1 and p21(-PCNA) overexpression in response to adenovirus infection was evident by Western blot analysis. IC(25) concentrations of each virus were used for each treatment in vitro to detect cooperative effects on cell death.

p53 gene transfer does not enhance E2F-1-mediated apoptosis in human colon cancer cells.

E2F-1 and p53 are sequence specific transcription factors that are intimately involved in the regulation of the cell cycle. In addition to their role in cell cycle control, both E2F-1 and p53 have been identified as tumor suppressors and mediators of apoptosis. We have shown previously that adenoviral-mediated E2F-1 overexpression induces efficient apoptosis in colon adenocarcinoma cells.

Adenovirus-mediated E2F-1 gene transfer induces an apoptotic response in human gastric carcinoma cells that is enhanced by cyclin dependent kinase inhibitors.

E2F -1 is a transcription factor that regulates cell cycle progression into S-phase. Deregulation of E2F-1 activity has been associated with cellular commitment to apoptosis. Also critical in the regulation of S-phase are the actions of the cyclin dependent kinases, Cdk2 and cdc2.

Adenovirus-mediated E2F-1 gene transfer efficiently induces apoptosis in melanoma cells.

Background: E2F-1 is a transcription factor that stimulates cellular proliferation and cell cycle progression from G(1) to S-phase. Somewhat paradoxically, E2F-1 also has the properties of a tumor suppressor. Overexpression of E2F-1 has been shown to induce apoptosis in some cancer cells.

Adenovirus-mediated E2F-1 gene transfer inhibits MDM2 expression and efficiently induces apoptosis in MDM2-overexpressing tumor cells.

The oncoprotein MDM2 binds and inactivates p53. MDM2 also binds to the tumor suppressor pRB, as well as E2F-1. E2F-1 is a transcription factor that regulates S phase entry and has been shown to cause apoptosis in some cell types when overexpressed.

Positional asphyxia during law enforcement transport.

Three cases of positional asphyxia are described that occurred while victims were in a prone position in rear compartments of police patrol cars. These deaths are attributed to positional asphyxia. Autopsy findings and specific scene and circumstantial correlations of the investigation are discussed with emphasis placed on the limitations of interpretation of the anatomic changes at autopsy.

Interaction of Zn2+ and Eu3+ with bovine liver glutamate dehydrogenase.

Bovine liver glutamate dehydrogenase is potently inhibited by Zn2+ ions. At pH 7.0 a kinetic dissociation constant for Zn2+ of 18 microM is obtained.
