During operation of most water treatment plants, spent filter backwash water (SFBW) is generated, which accounts about 2-10% of the total plant production. By increasing world population and water shortage in many countries, SFBW can be used as a permanent water source until the water treatment plant is working. This data article reports the practical method being used for water reuse from SFBW through different method including pre-sedimentation, coagulation and flocculation, second clarification, ultra filtration (UF) and returned settled SFBW to the beginning of water treatment plant (WTP). Also, two coagulants of polyaluminum ferric chloride (PAFCl) and ferric chloride (FeCl) were investigated with respect to their performance on treated SFBW quality. Samples were collected from Isfahan's WTP in Iran during spring and summer season. The acquired data indicated that drinkable water can be produced form SFBW by applying hybrid coagulation-UF process (especially when PAFCl used as coagulant).

Multidrug resistance (MDR) infectious wounds are a major concern due to drug resistance, leading to increased patient morbidity. Lichenysin (LCN), a lipopeptide and biosurfactant obtained from certain strains of , has demonstrated an excellent antimicrobial property. The present study focuses on the fabrication and comprehensive evaluation of LCN-incorporated poly(vinyl alcohol) (PVA)/polycaprolactone (PCL)-based nanofiber scaffolds using an electrospinning technique as a potential wound healing biomaterial for the treatment of MDR infectious wounds in diabetic rats.

In the present study, magnetic-calcined bamboo composite adsorbents (MCBC200, MCBC400, MCBC600, MCBC800, and MCBC1000) were prepared, and their physicochemical characteristics (scanning electron microscope images, differential thermogravimetric analysis, Fourier transform-IR, specific surface area, surface functional groups, and point of zero charge [pH]) were evaluated. Furthermore, the adsorption capacity of methylene blue (MB, cationic dye) using the prepared adsorbents was assessed. The value of pH and the specific surface area of MCBC400 were 7.

As a by-product of shellac resin, the high-value utilization of lac terpene acid (LTA) is a major challenge. In this study, a novel adhesive material, designated as A-LTA, was developed through a facile synthesis reaction between LTA and melamine, demonstrating significantly enhanced performance characteristics. The A-LTA adhesive, owing to its diverse functional groups, demonstrates exceptional cross-linking and polymerization capabilities under elevated temperatures, resulting in the formation of multiple chemical bonds and a highly dense network structure.

Ethnopharmacological Relevance: Guanxin II, proposed by Chen Keji (National master of traditional Chinese medicine), possesses cerebral-protective effect. Interestingly, its simplified prescription Danshen-Chuanxiong-Honghua (DCH) can also clinically ameliorate cerebral impairment and improve spatial cognitive deficits, similar to original formula's function.
Aim Of The Study: We aimed to elucidate the rationality of DCH's natural existence, qualitatively identify DCH-derived phytochemicals, thereby validate cerebral protective effect, and expose potential mechanism of DCH and its main absorbed compound ferulic acid (FA).
