Rare presentation of hepatic alveolar echinococcosis mimicking hepatocellular carcinoma.

A complex liver lesion presents a significant challenge in terms of diagnosis and management. This case is an illustrative example, highlighting the steps involved in managing such complex scenarios. This patient, in her early 20s, presented with a fever associated with worsening abdominal pain, as well as a background history of chronic abdominal pain, anorexia, vomiting, constipation and weight loss.

Ṯābit Ibn Qurra's contributions to toxicology.

Mankind has been familiar with poisons since ancient times. On the other hand, there is a wealth of knowledge in the medical books including medieval works of Middle Eastern polymaths such as Avicenna, "al-Rāzī," and "Ṯābit Ibn Qurra." This study presented and analyzed the knowledge of medical toxicology in one of the mainstay works of "Ṯābit Ibn Qurra" entitled "al-Ḏaḫira Fy Ꜥilm al-Tibb" also known as The Treasury of Medicine after the translation of the book from Arabic to English carefully and faithfully.

Alkyl ammonium hydrogen sulfate immobilized on FeO@SiO nanoparticles: a highly efficient catalyst for the multi-component preparation of novel tetrazolo[1,5-a]pyrimidine-6-carboxamide derivatives.

In this, a three-component reaction for the preparation of novel tetrazolo[1,5-a]pyrimidine-6-carboxamide derivatives from N,N'-(sulfonylbis(1,4-phenylene))bis(3-oxobutanamide), aldehydes and 1H-tetrazol-5-amine is reported. The application of FeO@SiO-(PP)(HSO) (A) as a catalyst afforded the desired products (a-a) in high yields in DMF as solvent as well as under solvent-free conditions.

Multi-Component Syntheses of Spiro[furan-2,3'-indoline]-3-carboxylate Derivatives Using Ionic Liquid Catalysts.

Two previously described Brønsted acidic ionic liquids, 3,3'-(1,6-hexanediyl)bis(1-methyl)-1-imidazolium hydrogen sulfate () and 1,1'-(1,6-hexanediyl)bis(pyridinium) hydrogen sulfate (), were used as catalysts for the preparation of spiro[furan-2,3'-indoline]-3-carboxylate derivatives via a three-component reaction of anilines, isatins (-alkyl-indoline-2,3-diones), and diethyl acetylenedicarboxylate, in high yields. The use of ultrasonic (US) irradiation led to the targeted products (-) in high yields ranging from 80% to 98%. Under the same conditions, the use of sulfuric acid and acetic acid as a Brønstedt catalyst did not yield the desired benchmark product .

Identification of groundwater nitrate sources in an urban aquifer (Alborz Province, Iran) using a multi-parameter approach.

High concentrations of NŌ in water resources are detrimental to both human health and aquatic ecosystems. Identification of NŌ sources and biogeochemical processes is a crucial step in managing and controlling NŌ pollution. In this study, land use, hydrochemical data, dual stable isotopic ratios and Bayesian Stable Isotope Mixing Models (BSIMM) were integrated to identify NŌ sources and estimate their proportional contributions to the contamination of the Karaj Urban Aquifer (Iran).
