Measurements of complement factor H-related protein (BTA-TRAK (TM) assay) and nuclear matrix protein (NMP22 assay) - Useful diagnostic tools in the diagnosis of urinary bladder cancer? [PDF]

open access: yes, 2003
Between 1997 and 2000 we investigated in a prospective study the voided urine samples of all consecutive patients undergoing cystoscopy independent from their clinical background (n=705) with the BTA-TRAK(TM) assay (Bard Diagnostics, Redmont, USA ...

The unpredictably eruptive dynamics of spruce budworm populations in eastern Canada

open access: yesPopulation Ecology, EarlyView.
We examine historical population data for spruce budworm from several locations through the period 1930–1997, and use density‐dependent recruitment curves to test whether the pattern of population growth over time is more consistent with Royama's (1984; Ecological Monographs 54:429–462) linear R(t) model of harmonic oscillation at Green River New ...

Functional Gait Assessment Tests in Elderly: A Systematic Review

open access: yesCaspian Journal of Neurological Sciences, 2023
Background: Due to the mobility problems of the elderly, it is better to use low-cost and applicable methods in any place, which do not require expertise to measure gait. One of these ubiquitous methods is functional gait assessment (FGA).

occumb: An R package for site occupancy modeling of eDNA metabarcoding data

open access: yesPopulation Ecology, EarlyView.
This study introduces a new R package, occumb, for the convenient application of site occupancy modeling using environmental DNA (eDNA) metabarcoding data. We outline a data analysis workflow, including data setup, model fitting, model assessment, and comparison of potential study settings based on model predictions, all of which can be performed using

Sensitivity and Specificity of Photoaptamer Probes [PDF]

open access: yesMolecular & Cellular Proteomics, 2003
The potential of photoaptamers as proteomic probes was investigated. Photoaptamers are defined as aptamers that bear photocross-linking functionality, in this report, 5-bromo-2'-deoxyuridine. A key question regarding the use of photoaptamer probes is the specificity of the cross-linking reaction.

Between Droughts and Floods: The Seasonal Response of Freshwater Snails in Artificial Reservoirs in the Brazilian Semiarid Region

open access: yesPopulation Ecology, EarlyView.
We investigate the seasonal dynamics of two freshwater snails, Biomphalaria straminea and Melanoides tuberculata, in artificial reservoirs of the Brazilian semiarid region. Despite regulated hydrology, B. straminea exhibited strong seasonal fluctuations associated with dry periods, while M. tuberculata maintained stable populations throughout the year,
