Acute non-ST segment elevation myocardial infarction as the first manifestation of Takayasu arteritis in a 16-year-old female patient: a case report and literature review.

Takayasu arteritis (TA) is now recognized worldwide and is a disease that mainly affects the aorta and its main branches. TA rarely involves the small or medium-sized vessels. Certain vascular lesions, such as arterial stenosis, occlusion, and aneurysm are common with TA.

Pilot-scale study on seeded precipitation assisted nanofiltration for flue-gas desulfurization wastewater softening.

In order to reduce the cost of chemical softening, the seeded precipitation assisted nanofiltration (NF) process was introduced into zero liquid discharge (ZLD) of flue-gas desulfurization (FGD) wastewater treatment. A pilot-scale system was developed and run for 168 h in a coal-fired power plant. The system mainly consists of lime softening, ambient temperature crystallizer (ATC) and NF, in which the raw water treatment capacity was 1 m/h.

Catestatin prevents endothelial inflammation and promotes thrombus resolution in acute pulmonary embolism in mice.

Catestatin (CTS), a catecholamine-release inhibitory peptide, exerts pleiotropic cardiac protective effects. Pulmonary embolism caused by deep vein thrombosis involving vascular dysfunction. The present study aims to investigate the effects of CTS on thrombus formation that may inhibit the development of pulmonary embolism and its potential pathway.

A systematic approach to measure the contents of mono- and di-sulfonates in petroleum sulfonates by the novel method of acid-base titration coupled with traditional two-phase titration.

Petroleum sulfonates are broadly employed to increase the oil recovery efficiency in tertiary recovery, while the content of di-sulfonates in petroleum sulfonates is a critical factor in the flushing efficiency, because it adversely impacts the decrease of oil-water interfacial tension. Thus far, no methods have been considered convenient and reliable to determine the contents of mono- and di-sulfonates besides the traditional extraction method. This study established a simple and practical approach of acid-base titration coupled with traditional two-phase titration to measure the contents of mono- and di-sulfonates in petroleum sulfonates.

Systematic evaluation of petroleum sulfonate: polarity separation and the relationship between its structure and oil recovery properties.

Petroleum sulfonate is one of the most important surfactants in the tertiary oil recovery process. However, its complex composition significantly impedes its evaluation, and the relationship between its structure and oil recovery properties is still unclear. In this study, the actives of petroleum sulfonate are subdivided into seven components, a-g, with different polarities column chromatography.
