The Future Of Teratology Research Is In Vitro, Jarrod Bailey, Andrew Knight, Jonathan Balcombe

Jarrod Bailey, PhD

Birth defects induced by maternal exposure to exogenous agents during pregnancy are preventable, if the agents themselves can be identified and avoided. Billions of dollars and manhours have been dedicated to animal-based discovery and characterisation methods over decades. We show here, via a comprehensive systematic review and analysis of this data, that these methods constitute questionable science and pose a hazard to humans. Mean positive and negative predictivities barely exceed 50%; discordance among the species used is substantial; reliable extrapolation from animal data to humans is impossible, and virtually all known human teratogens have so far been identified in spite …

Hepatitis B Virus Subgenotypes D1 And D3 Are Prevalent In Pakistan, Anwar Ali Siddiqui, Saeeda Baig, Runu Chakravarty Runu Chakravarty, Tariq Moatter

Anwar Ali Siddiqui

Background:

As the hepatitis B genotyping is important for assessing its clinical implications and geographical distribution, the sub-genotypes have been found useful for determination of specific genomic markers related to hepatocarcinogenesis. In Pakistan, there is no reported data on molecular evolutionary analysis of HBV. A study was, therefore, much needed to evaluate the spectra of mutations present in the strains prevalent here.

Findings:

To confirm specificity of PCR typing, phylogenetic analysis of the pre-S1 region and the divergence was studied through 13 sequences of 362 bp (accession number EF432765 – EF432777). A total of 315 serum samples, selected from HBsAg …

Tom Curran, Phd, Frs, Named Executive Director Of Children's Research Institute, Children's Mercy Hospital

Our Story Continues

Tom Curran, PhD, FRS, has been named Chief Scientific Officer and Executive Director of the Children’s Mercy Children’s Research Institute (CRI), effective Feb. 1 [2016]

The Children’s Research Institute at Children’s Mercy Kansas City was established last year to build on the hospital’s century-long history in pediatric research and to focus the hospital’s future research efforts in four key areas:

• Pediatric Genomic Medicine
• Clinical Pharmacology
• Health Services and Outcomes
• Health Care Delivery

Models For Hsv Shedding Must Account For Two Levels Of Overdispersion, Amalia Magaret

UW Biostatistics Working Paper Series

We have frequently implemented crossover studies to evaluate new therapeutic interventions for genital herpes simplex virus infection. The outcome measured to assess the efficacy of interventions on herpes disease severity is the viral shedding rate, defined as the frequency of detection of HSV on the genital skin and mucosa. We performed a simulation study to ascertain whether our standard model, which we have used previously, was appropriately considering all the necessary features of the shedding data to provide correct inference. We simulated shedding data under our standard, validated assumptions and assessed the ability of 5 different models to reproduce the …

Privatization Of Biomedical Research: A Short Term Answer With Long Term Consequences, Frederick Azalekor

Nebraska College Preparatory Academy: Senior Capstone Projects

Biomedical research owned by the government is now available to be owned by private institutions. This results in stagnant innovations because researchers have trouble with all the restrictions that are placed by private institutions. Privatization of biomedical research has short term positive effects but its negative effects are overarching and disastrous. One way to combat this, is for licenses to be deployed slowly with future consequences in mind.

• Privatization has short term benefits but long term disadvantages are disastrous. • To reduce damaging effect, privatization must be deployed slowly and carefully. • Patents or proprietary ownership must be given …
