Engineering of redox-triggered polymeric lipid hybrid nanocarriers for selective drug delivery to cancer cells.

Tunable redox-sensitive polymeric-lipid hybrid nanocarriers (RS-PLHNCs) were fabricated using homogenization and nanoprecipitation methods. These nanocarriers were composed of novel redox-cholesterol with disulfide linkages and synthesized by conjugating cholesterol with dithiodipropionic acid esterification. Berberine (BBR) was loaded into the fabricated nanocarriers to investigate the selective uptake of BBR by cancer cells as well as its release and enhanced cytotoxicity.

Mucosal melanoma of hard palate.

Melanoma arising in the hard palate is an exceedingly rare entity, comprising a minute fraction of all melanoma cases. The absence of specific clinical signs often leads to delayed diagnosis and subsequent challenges in treatment planning. We discussed the existing literature to elucidate the epidemiology, risk factors, and molecular pathways associated with melanoma of the hard palate.

Perception of undergraduate medical students on learning physiology: A descriptive cross-sectional study in a medical school of South India.

Background: Understanding the various principles in physiology is very important for medical students to apply their knowledge in clinical practice. Most of the students learn physiology just to clear exams. There is a need to understand the student's perception on the significance of learning physiology in medical colleges, its role in clinical practice, research, and the subject of career choice.

Dual drug nanoparticle synergistically induced apoptosis, suppressed inflammation, and protected autophagic response in rheumatoid arthritis fibroblast-like synoviocytes.

Rheumatoid arthritis (RA) is a chronic immune-mediated joint inflammatory disorder associated with aberrant activation of fibroblast-like synoviocytes (FLS). Recently, FLS gained importance due to its crucial role in RA pathogenesis, and thus, targeting FLS is suggested as an attractive treatment strategy for RA. FLS-targeted approaches may be combined with disease-modifying antirheumatic drugs (DMARDs) and natural phytochemicals to improve efficacy in RA control and negate immunosuppression.

Silver molybdate: an excellent optical limiting material under nanoregime for photonic device application.

There is a mounting demand for nonlinear optical materials with superior optical limiting performance which has a noticeable impact on protecting the delicate optical components from laser-induced damage. Transition metal molybdates have garnered attention in the nonlinear optics field due to their outstanding optical and luminescent properties, which give rise to widespread applications in next-generation optoelectronics devices. The structural confirmation of the as prepared silver molybdate nanoparticles were made by XRD and Raman spectroscopy analysis.
