One barrier to diagnosis is the limited availability of spirometry testing, but in adults at risk for COPD, a normal pre-bronchodilator (pre-BD) peak expiratory flow (PEF) may rule out clinically significant COPD. Objective: To identify post-BD airway obstruction using data from 13 708 ...
asymptomatic children with asthma who have normal peak flow rates and suggest that frequent assessment of FEF 25–75 is required, as well as daily monitoring of symptoms and peak flow both in trials of drug therapy and for more optimal assessment of the effectiveness of therapy in clinical ...
The increased peak flow in the feet down tilted position is explained by passive dilatation of the vessels due to increased hydrostatic pressure. It is suggested, that measurement of maximal ischaemic exercise blood flow in the tilted position may be a more sensitive procedure for detection of ...
A tilting procedure, that increases the leg blood flow after maximal ischaemic exercise by 65% in normal persons, was used in a series of long-term juvenil
High-resolution computed tomography (CT) datasets of all patients were analysed retrospectively for seven predefined age groups (ten-year increments, from < 25 to ≥ 75). A structured scoring system was applied to assess sclerosis, osteophytes, joint space alterations, and anatomical form...
To assess if the microdissected crypts each contained cells originating from a single adult stem cell, the variant allele frequency (VAF) distribution was assessed for each crypt. All crypts showed a VAF peak around 0.5 and a median VAF > 0.3, confirming their clonal nature (Supplementary ...
To study brain development, researchers want to examine the brain tissues from adult guinea pigs. How many cells must the researchers select (randomly) so as to be 95% sure that the sample mean is within 3.4 cells of the population mean? Assume that a previous study has shown σ = 10 ...
we explored sequence polymorphisms of the source elements using long-read WGS of two colorectal clones. Population-prevalent source elements were predominantly in the older L1 subfamilies (such as pre-Ta and PA2), as suggested previously12, and harboured open reading frame-disrupting mutations more...
The pattern of VH3 abundance also differed between fetal and adult B-lineage development. Fetal VH3 transcripts appeared to increase sharply and to peak at the late pre-B–cell stage (fraction 4), following the same pattern seen for the IgH transcripts discussed above. However, in the adult...
