Background: The effectiveness of whey obtained by either enzyme (sweet) or acid treatment on wound healing remains unclear. This study investigated the effectiveness of camel and bovine whey prepared enzymatically (CSW and BSW) or by pH reduction (CAW and BAW). After removing the cream from milk, HCl or rennet was used to remove casein, resulting in acid or sweet whey, respectively, followed by lactose removal using dialysis.

Article Synopsis
  • The study investigates the use of adipic acid as a catalyst for hydrogen production through hydrolysis, ethanolysis, and methanolysis reactions of sodium borohydride (NaBH) for the first time.
  • Various concentrations of adipic acid solutions (0.1-0.5 M) with methanol and ethanol were tested at different temperatures (30-50 °C) to determine their effectiveness in hydrogen conversion.
  • The findings indicate that ethanolysis and methanolysis reactions achieve total hydrogen conversion quickly (within 4-5 seconds) at certain concentrations, while hydrolysis reactions only reach total conversion at higher temperatures (50 °C).

The current study focuses on the synthesis and characterization of six benzenesulfonamide-based Schiff base derivatives (7-12) with various electron-withdrawing and electron-donating substituents (-F, -CI, -Br, -CH, and -OCH) and the assessment of their antiproliferative activities against human lung (A549) and liver (HepG2) cancer cell lines using in vitro and in silico approaches. The structures of the synthesized compounds (7-12) were elucidated by elemental analysis and FT-IR, 1D (H, C, APT, and DEPT-135), and 2D (HMQC and HMBC) NMR spectroscopies. The cytotoxic activities of the targeted compounds were determined at various concentrations against these cancer cell lines for 72 h, using the MTT method.

This work presents a novel deep eutectic solvent (DES) formed of octylamine and oxalic acid (Oct-Oxa) that was effectively used to separate Sudan II dye from food and water samples. The prepared DES was characterized using Fourier transform infrared spectroscopy (FT-IR) and carbon-13 nuclear magnetic resonance (C NMR). Key parameters were optimized, including a short ultrasonication time of 30 s and a very low DES volume of only 500 μL that could be separated within one minute of centrifugation.
