[Role of macrophage polarization in hypertension and traditional Chinese medicine intervention: a review].

Hypertension is known to be a chronic inflammatory state and a key risk factor for heart failure, coronary heart disease, and atherosclerosis. Macrophages in the circulatory system are the main cell group that constitutes the immune system and participates in the inflammatory response. Depending on the local microenvironment, macrophages can be polarized into pro-inflammatory(M1) and anti-inflammatory(M2) phenotypes.

Topics in Antivax and Provax Discourse: Yearlong Synoptic Study of COVID-19 Vaccine Tweets.

Background: Developing an understanding of the public discourse on COVID-19 vaccination on social media is important not only for addressing the ongoing COVID-19 pandemic but also for future pathogen outbreaks. There are various research efforts in this domain, although, a need still exists for a comprehensive topic-wise analysis of tweets in favor of and against COVID-19 vaccines.

Objective: This study characterizes the discussion points in favor of and against COVID-19 vaccines posted on Twitter during the first year of the pandemic.

De novo sequencing and transcriptome analysis of Ustilaginoidea virens by using Illumina paired-end sequencing and development of simple sequence repeat markers.

Ustilaginoidea virens is the causal agent of rice false smut, which is a rice disease of increasing importance worldwide that has caused with the quantitative and qualitative rice losses. However, research on the pathogenic mechanism of U. virens is limited.

Age-associated changes in gene expression of goat oocytes.

Oocyte aging severely decreases the quality of oocytes, which hampers fertilization and subsequent embryo development. In the present study, age-dependent molecular changes in goat oocytes were investigated. First, the quality of goat oocytes with various in vitro culture times (24, 30, 36, 48, and 60 hours) was evaluated on the basis of developmental rates of parthenogenetically activated embryos and apoptosis of cumulus cells (CCs).

Layer-by-layer assembly of polyelectrolyte and graphene oxide for open-tubular capillary electrochromatography.

In this paper, open-tubular capillary column coated with graphene oxide (GO) was prepared through ionic adsorption of negatively charged GO nanosheets onto the capillary wall pre-modified with positively charged poly(diallydimethylammonium chloride) (PDDA). Thus prepared coating was very stable and could endure over 200 separations. The electroosmotic flow (EOF) characteristics of bare fused silica capillary column, PDDA coated column, and GO-PDDA coated column (GO-PDDA@column) were investigated by varying the percentage of methanol in buffer and the buffer pH value.

Capillary column coated with graphene oxide as stationary phase for gas chromatography.

The graphene oxide (GO) is carbon based material that has high surface area, high adsorption ability, and is stable at high temperature. In this work, the GO phase was prepared and used for gas chromatographic separation. GO nanosheets were covalently bonded onto the inner surface of fused silica capillary column using 3-aminopropyldiethoxymethyl silane as cross-linking agent.

Capillary coated with graphene and graphene oxide sheets as stationary phase for capillary electrochromatography and capillary liquid chromatography.

Graphene oxide (GO) nanosheets were immobilized onto the capillary wall using 3-aminopropyldiethoxymethyl silane as coupling agent. Graphene coated column (G@column) was fabricated by hydrazine reduction of GO modified column. Scanning electron microscopy (SEM) images provided visible evidence of the GO grafted on the capillary wall.
