The phrase "ais block" is not correct in standard written English and does not convey a clear meaning.
Without context, it is difficult to determine when it could be used, as it appears to be a fragment or a typo.
Example: "The ais block needs to be adjusted for better airflow."
Alternatives: "aisle block" or "air block".
AIs block endogenous synthesis of oestrogen but have no effects on the synthesis of other steroid classes, which can interact with ER (such as adrenal androgens) [ 2], and on exogenous oestrogens/oestrogenic compounds, including synthetic estrogens, industrial pollutants, and phytoestrogens.
TAM acts by blocking estrogen binding to its receptor, while AIs block estrogen production [ 8].
Although the pathophysiology of AIAA remains unclear, estrogen suppression is hypothesized to play an important role, since AIs block the final step in estradiol and estrone synthesis [ 7].
In postmenopausal women with ER + breast cancer, particularly those being treated with AIs, circulating levels of estradiol (E2) are extremely low, while circulating androgen levels are increased [ 12] since AIs block the conversion of androgens to estrogen.
In contrast, in postmenopausal women with ER + breast cancer (which represent the majority of cases), and particularly in those being treated with AIs, circulating levels of E2 are extremely low, while circulating androgen levels are slightly elevated since AIs block the conversion of androgens to estrogen [ 12].
APs are not required for rapid AIS plasticity in rat DGCs: blocking NaV with 1 μM tetrodotoxin (TTX) had no effect on the shortened AnkG distribution produced by 3-hr depolarization.
The model was validated and Ais determined using a 3×3 factorial experimental design blocked for experimental day.
This paper proposes a novel AIS with abilities to identify and properly manipulate building blocks in optimization problems.
Recent comparisons of AIs with the most widely used oestrogen receptor blocking drug tamoxifen indicate that, in general, AIs result in increased response rates and greater durations of response.
Blocking calcineurin with 1 μM cyclosporin (CsA) prevented AIS shortening after 3-hr depolarization, leaving a small (<2 μm) decrease in AIS length that was no longer statistically significant (Bonferroni post-test, p > 0.05) or carried by CaMKII signaling.
Blocking KCNQ potassium channels, which cluster preferentially at the AIS [88], with the antagonists Xe-991 (100 µM) and linopirdine (100 µM) produced broad spikes that were initiated at much less depolarised membrane potentials, making cells significantly more excitable.
