Atherosclerosis is the leading cause of cardiovascular diseases in Mexico and worldwide. The membrane transporters ABCA1 and ABCG1 are involved in the reverse transport of cholesterol and stimulate the HDL synthesis in hepatocytes, therefore the deficiency of these transporters promotes the acceleration of atherosclerosis. MicroRNA-33 (miR-33) plays an important role in lipid metabolism and exerts a negative regulation on the transporters ABCA1 and ABCG1.

One of the main characteristics of probiotics is their ability to stimulate and modulate the immune response regardless of their viability. (Lc) can stimulate local and systemic immunity, in addition to the activation of macrophages at sites distant from the intestine. Activated macrophages limit the replication of intracellular protozoa, such as , through the production of nitric oxide.

Article Synopsis
  • Gold nanoparticles are being used in engineering and medical sciences due to their unique properties, particularly surface plasmon resonance and high density, which enhance cellular uptake.
  • The research explores a non-viral gene transfer method utilizing gold nanoparticles functionalized with organic polymers, specifically using sodium borohydride and chitosan oligosaccharides for synthesis.
  • Transfection efficiency experiments showed that nanoparticles conjugated with chitosan oligosaccharides achieved a 60% transfection rate in cell cultures, highlighting their potential in gene therapy applications.

The thermal properties of nanofluids are an especially interesting research topic because of the variety of potential applications, which range from bio-utilities to next-generation heat-transfer fluids. In this study, photopyroelectric calorimetry for measuring the thermal diffusivity of urchin-like colloidal gold nanofluids as a function of particle size, concentration and shape in water, ethanol and ethylene glycol is reported. Urchin-like gold nanoparticles were synthesised in the presence of hydroquinone through seed-mediated growth with homogeneous shape and size ranging from 55 to 115 nm.
