The overall aim of the study is to assess the effect of school-based Human Papillomavirus (HPV) vaccination by comparing type-specific HPV prevalence between vaccinated and non-vaccinated women born in 1997. Women born in 1997, residence to Norway in 2009 (the year of vaccine initiation of the 1997-cohort) are invited to participate in the study.
This cohort is amongst the first that was offered HPV vaccine in an organized vaccination programme globally. The women will be recruited through Facebook ads. The study will enable us to measure differences in the prevalence of HPV types in vagina and the mouth between vaccinated and non-vaccinated young women in Norway.
The womens vaccination status will be validated by linkage to the Norwegian Immunisation Registry (SYSVAK) and their residence status will be validated through linkage to the Norwegian Population Registry.

This study will evaluate whether babies are more at risk of developing breathing problems if their mothers carry group B streptococci (GBS) in vagina/rectum, and whether the breathing pr...
Sample size definition provides important information, allowing the groundwork for transparent reporting. The sample predefinition allows the trial to be large enough to be able to addres...

Biological and pharmaceutical samples represent formidable challenges in sample preparation that hold important consequences for bioanalysis and genotoxic impurity quantification. This Feature will em...
Sample size determination is a fundamental step in the design of experiments. Methods for sample size determination are abundant in the univariate, but scarce in the multivariate case. Omics data are ...
We propose an extension of ptychography where the target sample is scanned separately through several probes with distinct amplitude and phase profiles and a diffraction image is recorded for each pro...
A 550-fold increase in the liquid state (13)C NMR signal of a 50μL sample was obtained by first hyperpolarizing the sample at 20K using a gyrotron (260GHz), then, switching its frequency in order to ...
The analysis of a chemical substance by inserting a sample into a carrier stream of reagent using a sample injection valve that propels the sample downstream where mixing occurs in a coiled tube, then passes into a flow-through detector and a recorder or other data handling device.
A type of scanning probe microscopy in which a very sharp conducting needle is swept just a few angstroms above the surface of a sample. The tiny tunneling current that flows between the sample and the needle tip is measured, and from this are produced three-dimensional topographs. Due to the poor electron conductivity of most biological samples, thin metal coatings are deposited on the sample.
A solventless sample preparation method, invented in 1989, that uses a fused silica fiber which is coated with a stationary phase. It is used for sample cleanup before using other analytical methods.
The number of units (persons, animals, patients, specified circumstances, etc.) in a population to be studied. The sample size should be big enough to have a high likelihood of detecting a true difference between two groups. (From Wassertheil-Smoller, Biostatistics and Epidemiology, 1990, p95)
Differential thermal analysis in which the sample compartment of the apparatus is a differential calorimeter, allowing an exact measure of the heat of transition independent of the specific heat, thermal conductivity, and other variables of the sample.
Human Papillomavirus (HPV)
Human papilloma viruses (HPV) affect the skin and the moist membranes lining your body, for example, in your cervix, anus, mouth and throat. HPV is a common and highly contagious infection, with over three quarters of sexually active women acquiring it ...

A vaccine is a biological preparation that improves immunity to a particular disease. A vaccine typically contains an agent that resembles a disease-causing microorganism, and is often made from weakened or killed forms of the microbe, its toxins or one ...
