Lindelöf space, strongly Lindelöf subset, almost Lindelöf subset, and strongly almost Lindelöf subset

Description:
A subspace Y of a space X is almost Lindelöf (strongly almost Lindelöf) in X if for every open cover U of X (of Y by open subsets V of X), there exists a countable subset V of U such that Y ⊆ S {V : V ∈ V }. In this paper we investigate the relationships between relatively almost Lindelöf subset and relatively strongly almost Lindelöf subset by giving some examples, and also study various properties of relatively almost Lindelöf subsets and relatively strongly almost Lindelöf subsets.

Subject:
apolipoprotein J (clusterin), interleukin 1β, tumour necrosis factor α, THP-1 macrophages, and inflammation
Language:
English
Description:
Apolipoprotein J (clusterin) is a component of high-density lipoproteins, the high level of which is reversely correlated with the risk of coronary heart disease. In addition, it exerts anti-inflammatory and anti-apoptotic effects on endothelial cells and inhibits smooth muscle cell migration and proliferation, indicating that it may play a protective role in cardiovascular disease. However, the exact mechanisms by which this occurs remain unclear. This study aimed to clarify these underlying protective mechanisms by researching the inhibitory effects of apolipoprotein J via the NOD-like receptor protein 3 pathway on the inflammation induced by cholesterol crystals in THP‑1 macrophages. In culture, THP-1 macrophages were infected with adenoviral vectors containing apolipoprotein J genes and subsequently treated with cholesterol crystals. The inflammatory cytokines interleukin‑1β, interleukin 18 and tumour necrosis factor α were quantitatively measured with ELISA kits. NOD-like receptor protein 3, cysteinyl aspartate specific proteinase 1 and interleukin 1β were evaluated by Western blot and PCR analysis. As a result, apolipoprotein J expression was found to remarkably decrease the levels of inflammatory cytokines, including tumour necrosis factor α, interleukin 18 and interleukin 1β, secreted by THP‑1 macrophages. It was also found capable of inhibiting the levels of NOD-like receptor protein 3, cysteinyl aspartate-specific proteinase 1 and interleukin 1β both at the protein and mRNA levels. In the current study, we revealed that over-expression of apolipoprotein J attenuated the inflammation induced by cholesterol crystals through inhibition of the NOD-like receptor protein 3 inflammasome pathway.

5. Rapid protein turnover in photosystem. 2. Fundamental flaw or regulatory mechanism?

Description:
Pea (Písum sativum L.) leaves fully developed under either high or low irradiance were exposed for up to 30 h to dark oř limiting, saturating oř excessive iřřadiance. The time courses of degradation of a popidation of radioactively prelabelled Dl protein and the fluorescence parameter Fv/Fm, measured on intact leatf discs at room temperature were studied. The Dl protein degradation was shown to be dependent on irradiance but not directly correlated with changes in photosynthetic capacity. The irradiance dependence of Dl protein degradation was different in the two types of leaves and it occurred at a slow but significant rate in the daik. The irradiance dependence of Dl degradation tnay be associated with the 3-dimensional structure of the thylakoid membrane and is suggested to play a key role in flie regulation of radiant energy absorption and photosynthetic capacity of flie leaves.
