title: Engineered gastroretentive amorphous ferulate matrix: a novel raft-forming paradigm for enhanced bioavailability

description: This study aimed to enhance the solubility of ferulic acid using solid dispersion techniques and develop chewable tablets that neutralize stomach acid, form a protective gel layer, prevent gastric fluid reflux, and ensure prolonged retention in the stomach with controlled release of the active ingredient. Researchers developed solid dispersions of ferulic acid using Eudragit<sup>®</sup> E PO as a carrier, with a 1:2 w/w ratio, achieving the highest solubility (39.9 mg/mL). Chewable tablets were formulated by direct compression, incorporating sodium alginate as a gelling agent, calcium carbonate for calcium ions and carbon dioxide, HPMC as a release retardant, and mannitol as a diluent. All formulations rapidly formed a gel layer within 10 s, had a lower density than gastric fluid, and floated on 0.1 N hydrochloric acid for over 8 h. The optimal formulation demonstrated excellent physical properties, including a gel strength of 11.84 g, an acid neutralization capacity of 15.97 mEq, and reaching 80.58% over 8 h with gradual release. It exhibited significant antioxidant activity (IC<sub>50</sub> 6.74 µg/mL) in the DPPH assay and showed stronger anti-inflammatory effects in macrophage cells than indomethacin. These findings suggest this formulation could enhance ferulic acid’s effectiveness in treating gastric ulcers and preventing acid reflux.

title: Investigating the In Vivo Distribution Characteristics of Gel-in-Water Nanogel Emulsions and Demonstrating Their Efficacy in Treating C26 Tumor-Bearing Mice

description: Nanotechnology has been advancing drug delivery systems (DDSs) for decades. Nanoparticle DDSs, in which nanometric carriers deliver drugs to the target site, are highly valued for cancer treatment. In this study, based on nanoemulsion technology, gel-in-water (G/W) nanoemulsion was developed by using an organogel, i.e., 12-hydroxystearic acid and castor oil, followed by encapsulation of the model anticancer drug paclitaxel (PTX) within the nanogel droplets. The G/W was prepared using ultrasound and stabilized with a nonionic surfactant. The enhanced permeability and retention of G/W were investigated by encapsulating coumarin-6 and comparing it with an oil-in-water (O/W) nanoemulsion. Temporal changes in tissue distribution of both nanoemulsions were used to assess the effect of gelation on drug distribution. Regardless of the tissue type, the extraction efficiency of G/W was lower compared to O/W. The fluorescence intensity of coumarin-6 in G/W was higher compared to O/W. The size of G/W nanoparticles affects lung distribution and blood retention. PTX-loaded G/W (PTX-G/W) nanoparticles effectively treated colon cancer in vivo. They also exhibited antitumor activity against colon26 (C26) cells in vitro. The impact of particle size on the in vivo tissue distribution of G/W nanoemulsions suggests an improvement in drug delivery to the tumor site via nanoparticles.

title: Development and optimization of cilostazol loaded transethosomal gel for improved performance

description: Deep vein thrombosis (DVT) is the third major leading cause of mortality and morbidity after cardiovascular disease and stroke. Cilostazol (CLZ) being one of the antiplatelet agents is effectively used in DVT. However, its oral administration is associated with several problems, such as gastrointestinal side effects and extensive first-pass metabolism. Herein, CLZ-loaded transethosomes (CLZ-TEs) were prepared and incorporated in chitosan gel (CLZ-TEG) for transdermal administration. Box-Behnken Design Expert® software was used to statistically optimize CLZ-TEs. Particle properties, Transmission electron microscopy (TEM) and Fourier Transform Infrared spectroscopy (FTIR) analyses of CLZ-TEs were accomplished followed by <i>in vitro</i> release and permeation studies and its comparison with CLZ-TEG, CLZ-dispersion (Ds) and CLZ-G. Moreover, skin irritation and pharmacokinetics studies of the optimized CLZ-TEG were executed. The optimized CLZ-TEs showed a mean particle size of 174 nm, polydispersity index of 0.173, zeta potential of -30 mV and entrapment efficiency of 99%. TEM exhibited spherical nanovesicles and FTIR demonstrated compatibility of the excipients. Moreover, CLZ-TEG was homogeneous, smooth, and spreadable. Similarly, CLZ-TEG displayed sustained release and enhanced permeation of the CLZ. Furthermore, pharmacokinetic study showed significantly improved (p &lt; 0.05) bioavailability of CLZ-TEG when compared with CLZ-G and CLZ-Ds. It was concluded that CLZ-TEG may be a potential candidate for the management of DVT.

title: Cross-flow turbine’s CFD analysis for hydropower generation

description: The rising demand for affordable and efficient small-scale hydropower systems has driven renewed interest in Cross-Flow Hydro Turbines (CFHTs), particularly for rural and off-grid applications. CFHTs are recognized for their simple design, ease of maintenance, and low installation costs, making them well-suited for low-head sites. Despite limitations related to low head and discharge, they offer moderate efficiency and operational adaptability. This study presents an optimization-based investigation into CFHT performance by varying three key parameters: the number of blades (18 to 22), runner rotational speed (500, 600, and 700 RPM), and inlet blade angle (fixed at 10°), with a constant nozzle entrance arc of 65°. Unsteady computational fluid dynamics (CFD) simulations were conducted to analyze flow behavior and total pressure distribution, from which efficiency and other performance indicators were derived. The results show that the highest efficiency of 99.75% was achieved using 20 blades, a rotational speed of 600 RPM, and an inlet blade angle of 10°. These findings highlight the importance of blade count and operating speed in performance enhancement. This work offers practical insights for improving CFHT design, contributing to the development of efficient, small-scale hydropower solutions for low-head environments.
