Besides an increase in the corrected mean open duration, the opening frequency was also increased by zaprinast (Table 1, Zaprinast; P<0.05), and the combined effect was an elevated normalized NPo (P<0.05).

Plosone

Moreover, zaprinast (50 µM), a membrane-permeable, selective inhibitor of cGMP-specific PDE, also potentiated the single-channel activity of Kir6.2/SUR2A channels in cell-attached patches; the apparent opening frequency and open duration were both higher during zaprinast application (Fig. 1B).

Plosone

H2O2 (1 mM) increased the apparent opening frequency and the open duration of Kir6.2/SUR2A channels compared with the control obtained from the same cell-attached patch before application of H2O2 (Fig. 6A), without affecting the single-channel conductance.

Plosone

The increases in the opening frequency (P<0.01), the corrected mean open duration (P<0.05), and consequently the NPo (P<0.05), plus the reduction in the mean closed duration (P<0.0001), provided a kinetic explanation for Kir6.2/SUR2A channel activation induced by H2O2 (Table 2, H2O2).

Plosone

The normalized values of NPo, opening frequency, corrected mean open duration, and mean closed duration of Kir6.2/SUR2A channels obtained in intact HEK293 cells were significantly altered during H2O2 treatment (control as 1) (Table 2, H2O2; 9 patches; one-sample t test).

Plosone

The resulting closed and open duration distributions were fitted to a model containing two closed and two open states (2C-2O, Scheme 1) using the QuB program.

Therefore, higher hydrophobicity results in longer open durations (Table 2).

Biophysical Journal

The open durations of the heteromeric receptor were approximately 0.3, 4.5, 30 and 250 ms when activated with 100 μM 5-HT.

British Journal of Pharmacology

While the lengths of the brief open durations were not significantly different, the short, intermediate and long open durations of the 5-HT3A(QQN) receptor were significantly longer than the respective 5-HT3A QDA) receptor openings, suggesting that gating of these two receptors is distinct.

British Journal of Pharmacology

Both the 5-HT3A(QQN) and 5-HT3A QDA) receptors display four populations of open durations and three populations of closed durations when activated with 10 μM 5-HT (Table  2013, Supporting Information Figure S5).

British Journal of Pharmacology

Here we also found that the basic residue substitutions (I323K and I323R) not only reduced the single-channel conductance to about half but also significantly reduced the open durations (Table 2).

Expert writing Tips

Best practice

When using "open duration", clarify the factors that might influence or determine its final length to provide context and avoid ambiguity.

Common error

Avoid treating an "open duration" as though it has a definite end. Clearly communicate that the timeline is flexible and subject to change.

Linguistic Context

The phrase "open duration" functions as a compound noun phrase, where the adjective "open" modifies the noun "duration". It describes a period of time without a fixed endpoint. Ludwig examples showcase its use in scientific and general contexts.

FAQs

How can I use "open duration" in a sentence?

You might say, "The project will be conducted over an "open duration", allowing flexibility in scheduling", or "The consultation was open for the duration of the study until the final report was submitted."

What is an alternative to saying "open duration"?

Alternatives include "flexible duration", "unspecified duration", or "variable duration", depending on the context.

Is it correct to use "open-ended duration" instead of "open duration"?

Both "open duration" and "open-ended duration" are acceptable, but "open-ended duration" is more commonly used to emphasize the lack of a predetermined endpoint.

What does "open duration" imply in project management?

In project management, "open duration" typically suggests that the project timeline is adaptable and can be extended or modified based on evolving needs or circumstances.
