Overdose with the anesthetic propofol causes hematological cytotoxicity and immune cell alteration in an experimental ex vivo whole blood culture model.

Propofol, an anesthetic characterized by its benefits of rapid induction, maintenance, and recovery times, may cause cytotoxic effects, resulting in propofol infusion syndrome (PRIS). In addition to causing dyslipidemia in PRIS, our previous works showed that propofol overdose induced phagocyte apoptosis. This study, using an experimental ex vivo model of propofol treatment, investigated the possible cytopathology in the blood.

Anticancer polypyrrole-polyethylenimine drug-free nanozyme for precise B-cell lymphoma therapy.

As an alternative strategy for cancer treatment, the combination of cancer nanomedicine and immunotherapy is promising with regard to efficacy and safety; however, precise modulation of the activation of antitumor immunity remains challenging. Therefore, the aim of the present study was to describe an intelligent nanocomposite polymer immunomodulator, drug-free polypyrrole-polyethyleneimine nanozyme (PPY-PEI NZ), which responds to the B-cell lymphoma tumor microenvironment, for precision cancer immunotherapy. Earlier engulfment of PPY-PEI NZs in an endocytosis-dependent manner resulted in rapid binding in four different types of B-cell lymphoma cells.

Measurement of lipid droplets in peripheral immune cells shows an immunomodulatory effect on monocyte polarization in experimental dyslipidaemia.

Intracellular lipid droplet (LD) generation is the primary site of energy storage, which is necessary for physiological homeostasis but is related to pathological metabolic disorders. Lipid metabolism is critical for maintaining innate and adaptive immunity; however, it is mainly undefined in peripheral immune cells. Flow cytometry-based immune profiling in healthy peripheral blood cells showed significant original generation of LDs in dendritic cells (DCs, CD3CD19CD56CD11), monocytes (CD3CD19CD56CD14), natural killer cells (NK, CD3CD19CD56), and B cells (CD3CD19).

Development of a quasi-collimated UV LED backlight for producing uniform and smooth 3D printing objects.

3D printing techniques have great potential in the direct fabrication of microfluidic and many kinds of molds, such as dental and jewelry models. However, the resolution, surface roughness, and critical dimension uniformity of 3D printing objects are still a challenge for improvement. In this article, we proposed a 405nm light emitting diode (LED) backlight module based on stacks of structured films, and the full width half maximum (FWHM) of the angular distribution of this module is reduced to less than ± 15°.

The QseEF Two-Component System-GlmY Small RNA Regulatory Pathway Controls Swarming in Uropathogenic .

Bacterial sensing of environmental signals through the two-component system (TCS) plays a key role in modulating virulence. In the search for the host hormone-sensing TCS, we identified a conserved locus following , a small RNA (sRNA) gene in uropathogenic . Genes of constitute an operon, and QseF binding sites were found in the promoter region.

Higher Anti-Liver Fibrosis Effect of Cordyceps militaris-Fermented Product Cultured with Deep Ocean Water via Inhibiting Proinflammatory Factors and Fibrosis-Related Factors Expressions.

Deep ocean water (DOW) has been shown to enhance the functional components of fungi, resulting in increased health benefits. Therefore, using DOW for culturing fungi can enhance the cordycepin and adenosine of (CM) and its protective effects on the liver. In this study, the antiliver fibrosis effects and mechanisms of ultrapure water-cultured CM (UCM), DOW-cultured CM (DCM), synthetic water-cultured CM, DOW, cordycepin, and adenosine were compared in the liver fibrosis mice induced by intraperitoneal injections of thioacetamide (TAA).

Effect of the salts of deep ocean water on the production of cordycepin and adenosine of Cordyceps militaris-fermented product.

Cordyceps militaris is a type of entomogenous fungi and has been widely used as a medicinal fungus in Asia. Cordycepin produced by C. militaris has also been found to protect the liver.

Upregulation of endocan by Epstein-Barr virus latent membrane protein 1 and its clinical significance in nasopharyngeal carcinoma.

Endocan (or called Esm-1) has been shown to have tumorigenic activities and its expression is associated with poor prognosis in various cancers. Latent membrane protein 1 (LMP1) is an Epstein-Barr virus (EBV)-encoded oncoprotein and has been shown to play an important role in the pathogenesis of EBV-associated nasopharyngeal carcinoma (NPC). To further understand the role of LMP1 in the pathogenesis of NPC, microarray analysis of LMP1-regulated genes in epithelial cells was performed.

Monascin and ankaflavin have more anti-atherosclerosis effect and less side effect involving increasing creatinine phosphokinase activity than monacolin K under the same dosages.

Monacolin K has long been considered a major effective component in the hypolipidemic functions of Monascus . Monacolin K also serves as a well-known hypolipidemic medication, but its side effect myopathy is a concern. Monascin and ankaflavin, the yellow pigments produced by Monascus species, have been proven to possess hypolipidemic functions; however, no studies have compared the hypolipidemic effects of monascin, ankaflavin, and monacolin K under the same dosages.

Methanocalculus chunghsingensis sp. nov., isolated from an estuary and a marine fishpond in Taiwan.

Three novel halotolerant, hydrogenotrophic methanogens, designated strains K1F9705bT, K1F9705c and O1F9704a, were isolated from an estuary in Eriln Shi, Taiwan, and from a nearby marine water aquaculture fishpond. These isolates were irregular cocci that stained Gram-negative. Strains K1F9705bT and K1F9705c were non-motile, but strain O1F9704a was weakly motile with flagella.
