The phrase "acute barrier" is correct and usable in written English.
It can be used to describe a significant or sharp obstacle or hindrance in a particular context, such as in discussions about health, psychology, or physical barriers.
Example: "The acute barrier to effective communication in the team was the lack of trust among members."
Alternatives: "significant obstacle" or "sharp impediment."
Differences in osmoregulatory capacity and energetic requirements might cause fresh water to pose a more acute barrier for some populations and clades relative to others.
Additionally, neither DGAT-1 nor DGAT-2 expression changed following acute barrier disruption by tape-stripping in hairless mouse epidermis, indicating that basal DGAT expression suffices to meet the permeability barrier requirement in adult mice.
Although Elovl3-null mice show normal epidermal permeability barrier function at basal condition and contain normal levels of acylCer, a barrier recovery was delayed following acute barrier perturbation, 39 suggesting that ELOVL3 function is not compensated by other ELOVLs.
Whereas many CER supplementation experiments conducted after acute barrier disruption of the SC demonstrated recovery, 6 CER penetration, and thus its course of action, is likely to differ in healthy skin.
When skin structure and function were examined in the lipin-1 deficient mice, 43 neither epidermal morphology, surface pH, SC hydration, basal trans-epidermal water loss (a sensitive marker of permeability barrier function), or the recovery of permeability barrier function following acute barrier disruption were altered in the lipin-1 deficient mice compared to wild type controls (data not shown).
The aim of our study was to establish an in vitro model of acute barrier disruption, using Franz cell with full-thickness porcine and human skin [ 14– 16], to investigate various types of skin damage, based on Fick's law of diffusion [ 17, 18].
The first global and comprehensive analysis of the colon microflora in the DSS-induced colitis model revealed that acute barrier-damage in the colon is accompanied by accumulation of commensal E. coli.
Another study carried out in rural Tanzania supports the argument that high direct payments, together with the costs of unofficial payments, are acute barriers to the use of maternal services (40).
27 However, following acute permeability barrier disruption the restoration of permeability barrier function was accelerated by PPAR and LXR activators.
Mice fed with vitamin d-sufficient diet had a higher plasma level of 25(OH)D3 and were more resistant to ethanol-induced acute intestinal barrier injury compared with the vitamin d-deficient group.
Acute epidermal barrier disruption leads to an increase in HMGCR activity [ 29].
