Optimisation of albendazole delivery and assessment of anticancer potential in hepatocellular carcinoma (HepG2 cells) using surface modified nanostructured lipid carriers.

This study evaluated albendazole (ABZ) nanostructured lipid carriers (NLCs) for hepatocellular carcinoma treatment. ABZ-NLCs were prepared using emulsification-ultrasonication and optimised using a Box-Behnken design. Independent variables-lipids concentration (X), surfactant concentration (X), and sonication duration (X)-were assessed for their effect on mean diameter (Y), PDI (Y), and entrapment efficiency (Y).

New quinazolone-sulfonate conjugates with an acetohydrazide linker as potential antimicrobial agents: design, synthesis and molecular docking simulations.

A novel molecular design based on a quinazolinone scaffold was developed the attachment of aryl alkanesulfonates to the quinazolinone core through a thioacetohydrazide azomethine linker, leading to a new series of quinazolinone-alkanesulfonates 5a-r. The antimicrobial properties of the newly synthesized quinazolinone derivatives 5a-r were investigated to examine their bactericidal and fungicidal activities against bacterial pathogens like , (Gram-positive), , , (Gram-negative), in addition to (unicellular fungal). The tested compounds demonstrated reasonable bactericidal activities compared to standard drugs.

Downregulation of the NF-κB protein p65 is a shared phenotype among most anti-aging interventions.

Many aspects of inflammation increase with aging in mice and humans. Transcriptomic analysis revealed that many murine anti-aging interventions produce lower levels of pro-inflammatory proteins. Here, we explore the hypothesis that different longevity interventions diminish NF-κB levels, potentially mediating some of the anti-inflammatory benefits of lifespan-extending interventions.

Integrated Real-Time CMOS Luminescence Sensing and Impedance Spectroscopy in Droplet Microfluidics.

High-throughput biosensor screening and optimization are critical for health and environmental monitoring applications to ensure rapid and accurate detection of biological and chemical targets. Traditional biosensor design and optimization methods involve labor-intensive processes, such as manual pipetting of large sample volumes, making them low throughput and inefficient for large-scale library screenings under various environmental and chemical conditions. We address these challenges by introducing a modular droplet microfluidic system embedded with custom CMOS integrated circuits (ICs) for impedance spectroscopy and bioluminescence detection.

Zolmitriptan niosomal transdermal patches: combating migraine via epigenetic and endocannabinoid pathways and reversal of migraine hypercoagulability.

Conventional zolmitriptan (ZOL) has limited oral bioavailability, many adverse effects, and poor membrane penetrability that negatively influences its accessibility to its 5-HT receptor binding pocket, located transmemberanous. This work aimed at preparing transdermal ZOL-nanoformulation (niosomes) to surpass these limitations and to explore novel antimigraine mechanisms for ZOL via modulation of the epigenetically-altered chronification genes (RAMP-1, NPTX-2) or microRNAs and affecting the endocannabinoid CB-1/MAPK pathway. The prepared ZOL niosomes (F) exhibited %EE of 57.

Both compounds 1a (pyridine-thiourea precursor) and 8a (pyridine-5-acetyl-thiazolidin-4-one hybrid) exhibited excellent anti-proliferative activity against HEp-2 (IC = 7.

Myricetin-loaded SBA-15 silica nanoparticles for enhanced management of pyrexia, pain, and inflammation through modulation of MAPK/NF-κB and COX-2/PGE-2 pathways: Evidence from the biochemical, histological, and metabolomic analysis.

Myricetin (MYR) is a natural flavonoid that has several biological functions. However, some of its beneficial effects are diminished due to low water solubility, stability, and bioavailability. Herein, several kinds of silica nanoparticles (MCM-41 and SBA-15) were loaded with MYR to improve its biological activity as an analgesic, antipyretic, and anti-inflammatory component, thereby overcoming its drawbacks.

Benzenesulfonohydrazide-tethered non-fused and fused heterocycles as potential anti-mycobacterial agents targeting enoyl acyl carrier protein reductase (InhA) with antibiofilm activity.
