Application of Sorbents for Oil Spill Cleanup Focusing on Natural-Based Modified Materials: A Review.

Conventional synthetic sorbents for oil spill removal are the most widely applied materials, although they are not the optimal choices from an economic and environmental point of view. The use of inexpensive, abundant, non-toxic, biodegradable, and reusable lignocellulosic materials might be an alternative to conventional sorbents, with obvious positive impact on sustainability and circular economy. The objective of this paper was to review reports on the use of natural-based adsorbing materials for the restoration of water bodies threatened by oil spills.

Helicobacter pylori infection as a potential risk factor for multiple sclerosis.

Helicobacter pylori infection (Hp-I) has been associated with a wide spectrum of gastrointestinal and extra-digestive manifestations, including neurodegenerative diseases. Contradictory data have been published on Hp-I and multiple sclerosis (MS) association, with studies mainly using serology for Hp-I detection that cannot distinguish between active and past infections. We herein hypothesize that humoral and cellular immune responses induced by active Hp-I, beyond damaging locally the gastric mucosa, they may shape the character of systemic autoimmune responses, contributing to MS pathogenesis.

A perspective on risk factors for esophageal adenocarcinoma: emphasis on Helicobacter pylori infection.

Gastroesophageal reflux disease (GERD) and the increasing rate of its associated complications, including esophageal adenocarcinoma (EAC), has stimulated a plethora of studies attempting to evaluate provocative and protective factors. Helicobacter pylori (Hp) infection (Hp-I) was initially considered as a beneficial condition in GERD management based on rather limited data. Large-scale regional studies revealed an alternative approach, by suggesting a positive relationship between Hp-I and EAC development.

Acute Liver Failure: From Textbook to Emergency Room and Intensive Care Unit With Concomitant Established and Modern Novel Therapies.

Acute liver failure is a rare hepatic emergent situation that affects primarily young people and has often a catastrophic or even fatal outcome. Definition of acute liver failure has not reached a universal consensus and the interval between the appearance of jaundice and hepatic encephalopathy for the establishment of the acute failure is a matter of debate. Among the wide variety of causes, acetaminophen intoxication in western societies and viral hepatitis in the developing countries rank at the top of the etiology list.
