This study aimed to compare total polyphenol content and antioxidant activity of different forms of Al-Kbous black tea: teabag (TB), loose tea (LT), and opened teabag (OTB). Total polyphenol content was assessed by the Folin–Ciocalteu method, and DPPH and FRAP assays were used to determine antioxidant activity. The results revealed that TB and OTB have significantly more polyphenol than LT at the 5- and 15-minute brewing times. In addition, the data indicated that TB and OTB exhibit signif

An operational and eco-friendly technique was applied for the synthesis of silver nanoparticles (AgNPs) utilizing Arachis pintoi (A. pintoi) extract as a reducing agent. The features of synthesized AgNPs were investigated utilizing XRD, SEM, TEM, and FT-IR. The formation of AgNPs was verified by UV-Vis spectroscopy at the wavelength range of 400-450 nm. The proper conditions for AgNPs synthesis were determined such as the AgNO3 concentration of 1.75 mM, the volume ratio of AgNO3 solution/A. pint

One of the common malignancies of the gallbladder called Squamous cell carcinoma (SCC). Primary SCC of the gallbladder accounts for about 3.3% of the gallbladder cancers. Pure SCC is a very rare condition with an unknown histogenesis. Herein, we presented a 45-year-old female with a history of vague abdominal pains diagnosed with pure SCC. In the results of histopathological examination a well-differentiated keratinized SCC has been revealed. The patient was subjected to surgery based on the pre

There is now a greater concern in the marine organisms, especially algae, to find active ingredients to be used as therapeutic drugs in the medical applications. Delivery of drugs into the target organs with high specificity is now achieved when these compounds are coated on nanoparticles which improve the therapeutic properties of anti-tumor products. So, the current investigation aimed to assess the hepatoprotective capacity of silver nanoparticles (AgNPs) prepared by using ethanol extraction

New imidazole contents and thioxo-imidazolidin were synthesized by using simple methods. All compounds were synthesized by using the derivatives of aniline as starting materials, which were obtained from furfural and sodium nitrite. Hydrochloric acid derivatives (S6, S7) were obtained from the reaction of (S6, S7) with Thiosemicarbazide; while the reaction of (S13, S14) with chloroethyl acetate derivatives led to the formation of (S20, S21).
