Discerning protein pools by selective staining with self‐labeling tags

open access: yesFEBS Letters, EarlyView.
Cell surface proteins have an intra‐ and extracellular pool. Combining genetic fusion to self‐labeling tags that can be addressed with small molecule fluorophores allows separating these pools. We highlight recent developments and techniques for state‐of‐the‐art interrogation of cell surface proteins in the complex tissue setting.

A note on quantifying follow-up in studies of failure time

Controlled Clinical Trials, 1996
In a recent review of survival analyses published in cancer journals, Altman et al [l] found that about half of the papers did not include any summary of followup time. Only 31% of those papers that did report median follow-up specified the method used to compute it. Independently of Altman et al [I], we have surveyed articles in three medical journals-

Lenalidomide-dexamethasone versus observation in high-risk smoldering myeloma after 12 years of median follow-up time: A randomized, open-label study.

European Journal of Cancer, 2022
BACKGROUND Smoldering multiple myeloma (SMM) is a heterogeneous disease in terms of progression to myeloma (MM), but its standard of care continues to be observation.

Designing Follow-Up Times

Journal of the American Statistical Association, 2002
Studies of time-to-event are often conducted using follow-up sessions with subjects at risk. When these sessions must be widely spaced, their timing can significantly affect the efficiency of a study design. In this article we analyze the optimal timing of follow-up from a Bayesian decision theoretic standpoint.

The win ratio: Impact of censoring and follow‐up time and use with nonproportional hazards

Pharmaceutical statistics, 2019
The win ratio has been studied methodologically and applied in data analysis and in designing clinical trials. Researchers have pointed out that the results depend on follow‐up time and censoring time, which are sometimes used interchangeably.

Incidence, Timing, and Follow-Up of Periventricular Leukomalacia

American Journal of Perinatology, 1995
Screening cranial ultrasounds were performed on 115 very low birthweight infants during the first week of life. Fourteen infants (12%) developed changes of periventricular leukomalacia. All 14 weighted 1100 g or less at birth. Eight infants' initial studies were normal, four had intraventricular hemorrhage, and two had periventricular echo densities ...

Optimal timing of periodic follow-up advertising impulses

Zeitschrift für Operations Research, 1977
For well introduced commodities of mass consumption the optimal sequence of follow-up advertising is obtained. We focus on pulse campaign policies under an oligopolistic market structure with several types of consumer responses and compare the results for the associated stochastic reward process.

On the relevance of the long-time follow-up of the cyclocryotherapy

Der Ophthalmologe, 1999
In spite of the availability of cyclocryodestructive laser therapy there still appears to be an indication for cyclocryotherapy in different kinds of glaucoma.Cyclocryotherapy very often appears to be the operation of choice in cases of progressive functional visual loss if a patient is not sufficiently helped with the maximum tolerated medical therapy.

Drilling time follow-up with non-productive time monitoring

International Journal of Oil, Gas and Coal Technology, 2017
Drilling operations are validated whether the objectives of the wells are achieved within a time frame that is faster than the planned drilling time without compromising safety. The drilling costs in general are going to be reduced only if the drilling time is less than the planned program. While developing a field considerable numbers of similar wells
