Clean technology for synchronous sequestration of charged organic micro-pollutant onto microwave-assisted hybrid clay materials.

Clean technology for synchronous sequestration of charged organic micro-pollutant onto microwave-assisted hybrid clay materials. Environ Sci Pollut Res Int. 2020 Jan 11;: Authors: Bayode AA, Agunbiade FO, Omorogie MO, Moodley R, Bodede O, Unuabonah EI Abstract The Sustainable Development Goal 6 (SDG #6) of the United Nations (UN) is hinged on the provision, availability, and sustainability of water for the global populace by 2030. In a bid to achieve this goal, the quest to seek for ubiquitous and low-cost adsorbents to treat effluents laden with industrial dyes, such as methylene blue (MB), is on the increase in recent years. Acute exposure of humans to (MB) dye causes cyanosis, necrosis, and jaundice and even leads to death. In this research, zinc-modified hybrid clay composite adsorbent (materials from kaolinite and biomass (crushed Carica papaya seeds and/or plantain peel)) was developed via microwave route. This adsorbent was characterized using field emission scanning electron microscopy (FE-SEM), Fourier transform infrared (FTIR) spectroscopy, energy-dispersive X-ray (EDX), and high-resolution transmission electron microscopy (HR-TEM). These characterization techniques confirmed the success achieved in doping hybrid clay with Zn. These adsorbents were used to sequester cationic dye (MB) from aqueous solutions and textile effluent under various experimental conditions. The adsorption and desorption data obtained were analyzed using various kin...

This study aimed to compare the treatment outcomes and safety between stent placement with or without Iodine-125 (125I) seeds strand for patients with unresectable malignant obstructive jaundice (MOJ).Methods: A total of 84 patients with unresectable MOJ treated in our hospital were retrospectively included and divided into the stent group (n = 54) undergoing biliary stent placement and the stent + seeds group (n = 30) receiving stent placement with 125I seeds strand. The therapeutic outcome, postoperative complications, duration of patient survival and stent patency were compared ...

Authors: Tringali A, Boškoski I, Costamagna G Abstract Hilar cholangiocarcinoma (HCCA) involves a complex anatomical region where bile ducts, arteries, and veins create a complex network. HCCA can lead to biliary strictures at the main hepatic confluence, involving the right and left radicles. Endoscopic drainage of jaundiced patients with HCCA is challenging and carries a high risk of infective complications. HCCA needs a careful multidisciplinary evaluation to assess the indication and purposes (preoperative/palliative) of the biliary drainage. Biliary drainage in HCCA needs to be planned by magnetic reson...

Authors: Sánchez Fernández MJ, Sánchez Melgarejo JF, Pérez Fernández A Abstract With regard to the article published in your journal by Konstantinos Tsalis et al on Klatskin-mimicking lesions, we recently diagnosed a neuroendocrine tumor (NET) in the proximal biliary tract of a 78-year-old female with obstructive jaundice manifestations. A chest-abdomen-pelvis CT scan identified infiltrating ductal cholangiocarcinoma (Klatskin tumor, type IV in the Bismuth-Corlette classification with cT2N1 staging) and a liver mass in segment IV.

CONCLUSIONTraumatic rupture of a non-parasitic simple hepatic cyst is a very rare complication, but can lead to acute abdomen. In patients who are known to have non-parasitic simple hepatic cyst, rupture of cyst could be included in the differential diagnosis of acute abdomen.

Rationale: Solitary fibrous tumor(SFT) is a rare and distinct clinical entity. There are few descriptions in the literature regarding the PET manifestations of SFTs. Herein,we report a case of multiple malignant SFT with PET/CT imaging findings and PET/Contrast Enhanced CT image findings. Patient concerns: A 30-year-old woman presented with a history of a mass in neck increased gradually over 6 months without jaundice or other symptoms of obstruction.Serum laboratory results and tumor markers (AFP, CEA,CA199,CA724,CA153 and CA125)were normal. The whole body PET/CT scan showed lightly or mildly hypermetabolic and inhom...
