Comparison of Structural Features of CRISPR-Cas Systems in Thermophilic Bacteria

open access: yesMicroorganisms, 2023
The clustered regularly interspaced short palindromic repeat (CRISPR) is an adaptive immune system that defends most archaea and many bacteria from foreign DNA, such as phages, viruses, and plasmids. The link between the CRISPR-Cas system and the optimum

Synthetic control over orientational degeneracy of spacer cations enhances solar cell efficiency in two-dimensional perovskites

open access: yesNature Communications, 2019
Two-dimensional perovskites have emerged as more intrinsically stable materials for solar cells. Chemical tuning of spacer organic cations has attracted great interest due to their additional functionalities.

Definitions and pathophysiology of vasoplegic shock

open access: yesCritical Care, 2018
Vasoplegia is the syndrome of pathological low systemic vascular resistance, the dominant clinical feature of which is reduced blood pressure in the presence of a normal or raised cardiac output.

The choice of a spacer at the first stage of treatment for late deep periprosthetic hip joint infection

open access: yesГений oртопедии, 2021
. Introduction Periprosthetic infection in hip arthroplasty is a social and economic problem. Its main reason is multidrug resistance of microorganisms.

CRISPR-Cas systems feature and targeting phages diversity in Lacticaseibacillus rhamnosus strains

open access: yesFrontiers in Microbiology, 2023
One of the most important adaptive immune systems in bacteria against phages is clustered regularly interspaced short palindromic repeats (CRISPR) and CRISPR-associated (CAS) genes.

The Spacer Cations Interplay for Efficient and Stable Layered 2D Perovskite Solar Cells

open access: yesAdvanced Energy Materials, 2019
Organic spacer cations in layered 2D (A1)2(A2)n−1BnX3n+1 (where A1 is an organic cation acting as a spacer between the perovskite layers, A2 is a monovalent cation, e.g., Cs+,CH3NH3+, CH(NH2)2+) perovskite materials improve the long‐term stability of the

Comparison of effectiveness of metered dose inhaler with spacer and jet nebulizer in children aged 5–14 years with acute exacerbation of asthma: A pilot randomized controlled trial

open access: yesJournal of Pediatric Critical Care, 2021
Background: Asthma is a common and potentially serious chronic disease that imposes a substantial burden on patients, their families, and community. The main treatment of an acute exacerbation includes inhaled short-acting β2-agonists (SABA).

Spacer-Mediated Control of Coumarin Uncaging for Photocaged Thymidine

open access: yes, 2020
Despite its importance in the design of photocaged molecules, less attention is focused on linker chemistry than the cage itself. Here, we describe unique uncaging properties displayed by two coumarin-caged thymidine compounds, each conjugated with (2 ...
