TL;DR: The prolonged retention of microspheres in the stomach with sustained drug release could effectively act against Helicobacter pylori reservoirs in theomach and improve the therapeutic effect of amoxicillin trihydrate against H. pylora.
Abstract: Objectives In this study, a novel Sterculia foetida and pullulan-based semi-interpenetrating polymer network gastroretentive microsphere formulation was prepared using the emulsion crosslinking method and optimized by central composite design. Materials and methods The effects of the amounts of glutaraldehyde, S. foetida, and pullulan on the percent drug entrapment efficiency (EE), percent mucoadhesion at 12 h, and percent in vitro drug release at 12 h were optimized. The microspheres were characterized using scanning electron microscopy, fourier transform infrared spectroscopy, and differential scanning calorimetry. Results The formulation containing 4% v/v glutaraldehyde, 8.28% w/v pullulan, and 2.14% w/v S. foetida had 88.75±1.18% EE, 80.43±1.2% drug release at 12 h, and 81.73±1.50% mucoadhesion at 12 h, which was considered optimum and was used in an in vivo radiographic study. Conclusion Semi-interpenetrating polymer network microspheres loaded with amoxicillin trihydrate were successfully prepared using S. foetida and pullulan. The prolonged retention of microspheres in the stomach with sustained drug release could effectively act against Helicobacter pylori reservoirs in the stomach and improve the therapeutic effect of amoxicillin trihydrate against H. pylori.

TL;DR: In this paper, the solubility of Metolazone was improved by using various superdisintegrants such as sodium hydroxide at 0.1%, 0.25% and 0.5% concentrations.
Abstract: Objective: The objective of the current study is to improve the solubility of the Biopharmaceutical Classification System (BCS) Class-II drug, Metolazone, using various superdisintegrants. Methods: Starches were extracted from Sterculia foetida seed powder by water and alkali techniques i.e., sodium hydroxide at 0.1%, 0.25% and 0.5% concentrations. Several phytochemical and physicochemical parameters were evaluated on the extracted starches. Solid dispersions of Metolazone were prepared by the solvent evaporation technique using plasdone K-29/32 alone and by mixing plasdone K-29/32 with Sterculia foetida seed starch. Various physical parameters were evaluated for the prepared solid dispersions. Tablets were prepared using Metolazone solid dispersions and varying concentrations of Sterculia foetida seed starch by direct compression technique. Pre and post-compression parameters were evaluated along with in vitro drug release studies, characterization using Scanning Electron Microscopy (SEM) and stability studies. Results: Phytochemical tests showed the presence of starch in all extracts. Starch prepared from 0.1% sodium hydroxide (SFS2) showed best physicochemical properties. In vitro dissolution studies revealed that solid dispersion MS4 containing Metolazone and plasdone K-29/32 in 1:3 ratios showed better drug release. Formulation MPT6 containing MS5 solid dispersion with 15% w/w of SFS2 showed enhanced drug release. SEM studies revealed no major interactions between drugs and excipients. Accelerated stability studies showed that all tablets were stable. Conclusion: Sterculia foetida seed starch and plasdone K-29/32 have enhanced the solubility of Metolazone.

TL;DR: In this article, the effect of four process parameters, such as time, initial concentration, adsorbent dosage, and pH (3-10), was studied to determine the ideal conditions for the adsorption of zinc using Sterculia foetida.
Abstract: In the present work, optimization using central composite design (CCD) was studied to determine the ideal conditions for the adsorption of zinc using Sterculia foetida. The effect of four process parameters, such as time (30–240 min), initial concentration (10–100 mg/L), adsorbent dosage (0.1–1 g), and pH (3–10), was studied to obtain the best results for zinc adsorption on to Sterculia foetida using CCD. With these ranges, CCD has given 30 possible experimental runs. From the desirability values, the optimum values of initial concentration (20 mg/L), adsorbent dosage (0.1 g), and pH (10) were obtained with % removal value of 89.5. From the results obtained, it was clear that pH and initial concentration play a major role in the adsorption of zinc on to Sterculia foetida with p value equal to 0.0413 and 0.0005, respectively. The model F value obtained was 2.84, which implies that the quadratic model is significant.

TL;DR: Sterculia foetida fruit shell was used for the green synthesis of silver nanoparticles as mentioned in this paper, which showed superb coloration and also proven to be very good in antibacterial and ultraviolet protection properties even after ten washes.
Abstract: Sterculia foetida fruit shell was used for the green synthesis of silver nanoparticles. Optimized reduction of silver ion (Ag+) to metallic silver nanoparticles (Ag˚) was carried out at room temperature for 16hr. The reduced silver nanoparticles were characterized by UV-visible spectroscopy, particle size analyzer, FTIR and SEM analysis of treated cotton fabric not only showed superb coloration but also proven to be very good in antibacterial and ultraviolet protection properties even after ten washes.

TL;DR: It is reported that Sterculia foetida wood is suited for plywood making and other types of interior work in house construction and it has been proven that the strength of this wood offers the ability to plywood.
Abstract: There is a huge demand of solid wood for various utility in building construction. Nowadays, because of increased demand and high cost, plywood has been developed as an alternative to solid wood products. The plywood has increased dimensional stability, uniformity and higher mechanical strength, improved stress distributing properties, reduced processing cost and better appearance. There is a huge demand for plywood due to ever increasing real estate sector. At this juncture, it is reported that Sterculia foetida wood is suited for plywood making and other types of interior work in house construction. This besides, this species wood is easily workable with tools and glue and takes a finish well. It has been proven that the strength of this wood offers the ability to International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Volume 9 Number 12 (2020) Journal homepage: http://www.ijcmas.com
