Chronical alcohol abuse causes more than 200 diseases and/or symptoms and among these alcoholic liver disease (ALD) is of special importance since it occurs frequently and may be life-threatening. In Europe alcohol consumption as well as ALD increased as compared to the rest of the world. It has been estimated that in Europe approximately 500 000 people die every year due to ALD. ALD consists of alcoholic fatty liver, alcoholic steatohepatitis (ASH), alcoholic cirrhosis and hepatocellar cancer (HCC ). Alcohol hepatitis (AH) is a clinical feature with jaundice and liver failure and a high mortality...

Some water fleas such as Daphnia galeata and Bosmina longirostris are difficult to culture and use in ecotoxicity testing since they can easily become entrapped at the surface film. Cetyl alcohol was the most prevalent chemical used to prevent the entrapment of water fleas in previous studies. However, cetyl alcohol possesses a number of disadvantages including its toxicity and water insolubility. This study presents a novel method for preventing surface film entrapment of the water flea D. galeata and B. longirostris acute testing...

BACKGROUND AND AIMS: Concurrent alcohol use and waterpipe (WP) smoking is common among young adults. WP smokers are more than twice as likely to use alcohol as non-users and frequently consume alcohol immediately before and during a WP smoking session. It is unclear what impact alcohol has on WP smoking patterns and resultant exposure to tobacco-related toxicants. The current research aimed to understand the association between alcohol consumption and WP smoke exposure among WP lounge patrons...

Patulin is the main mycotoxin contaminating apples. During the brewing of alcoholic beverages, this mycotoxin is degraded to ascladiol, which is also the last precursor of patulin. The present study aims (1) to characterize the last step of the patulin biosynthetic pathway and (2) to describe the toxicity of ascladiol. A patE deletion mutant was generated in Penicillium expansum. In contrast to the wild strain, this mutant does not produce patulin but accumulates high levels of E-ascladiol with few traces of Z-ascladiol...

This study investigated the aerobic biodegradation of methyl tertiary-butyl ether (MTBE) by a microbial consortium in a continuous up-flow packed-bed biofilm reactor using tezontle stone particles as a supporting material for the biofilm. Although MTBE is toxic for microbial communities, the microbial consortium used here was able to resist MTBE loading rates up to 128.3 mg L-1 h-1, with removal efficiencies of MTBE and chemical oxygen demand (COD) higher than 90%. A linear relationship was observed between the MTBE loading rate and the MTBE removal rate, as well as between the COD loading rate and the COD removal rate, within the interval of MTBE loading rates from 11...

The information on burden of alcohol abuse in Iran is scarce. However, the available data show that mortality rates and frequency of its use have increased in the Iranian community. In particular, Iran occupies the 1st rank in the number of outbreak incidents and victims of toxic alcohols such as methanol in the Middle East. Mortality and morbidity of toxic alcohols are high if prompt diagnosis and treatment are not initiated rapidly. On-time diagnosis, proper case finding, and standard treatment have an essential role to reduce mortality and morbidity of toxic alcohols particularly blindness and other physical and psychological disabilities...

Different mixtures of monoterpenes (ketone, alcohol, and alkene) were loaded on paper discs and wax and their knockdown activities were evaluated against Culex pipiens adults. Some individual monoterpenes were also evaluated by residual toxicity technique. Citronella oil as a reference was also loaded separately or in combination with monoterpenes on paper discs and wax. The ketone monoterpenes mixture (camphor, menthone, carvone, and fenchone) on paper discs was the most active (KT50 = 17.20 min) followed by ketone monoterpenes with citronella oil (KT50 = 20...

Chronic jet lag induces spontaneous hepatocellular carcinoma (HCC) in wild-type mice following a mechanism very similar to that observed in obese humans. The process initiates with non-alcoholic fatty liver disease (NAFLD) that progresses to steatohepatitis and fibrosis before HCC detection. This pathophysiological pathway is driven by jet-lag-induced genome-wide gene deregulation and global liver metabolic dysfunction, with nuclear receptor-controlled cholesterol/bile acid and xenobiotic metabolism among the top deregulated pathways...

In cancer bioassays, inhalation, but not drinking water exposure to ethyl tertiary-butyl ether (ETBE), caused liver tumors in male rats, while tertiary-butyl alcohol (TBA), an ETBE metabolite, caused kidney tumors in male rats following exposure via drinking water. To understand the contribution of ETBE and TBA kinetics under varying exposure scenarios to these tumor responses, a physiologically based pharmacokinetic model was developed based on a previously published model for methyl tertiary-butyl ether, a structurally similar chemical, and verified against the literature and study report data...

The quantification of trace compounds in alcoholic beverages is a useful means to both investigate the chemical basis of beverage flavor and to facilitate quality control during the production process. One compound of interest is methanol which, due to it being toxic, must not exceed regulatory limits. The analysis of headspace gases is a desirable means to do this since it does not require direct sampling of the liquid material. One established means to conduct headspace analysis is selected ion flow tube mass spectrometry (SIFT-MS)...

The production and widespread use of poly- and perfluorinated alkyl substances (PFAS) has led to their presence in environment, wildlife, and humans. Particularly, the perfluorinated carboxylates (PFCAs) are pervasive throughout the world and have been found at ng/mL concentrations in human blood. PFCAs, especially those having longer carbon chain lengths (≥C6), are associated with developmental and hormonal effects, immunotoxicity, and promote tumor growth in rodents through their role as PPARα agonists...

Several phytoceuticals and extracts of medicinal plants are reported to mitigate deleterious effects of ionizing radiation. The potential of hydro-alcoholic extract of Clerodendron infortunatum (CIE) for providing protection to mice exposed to gamma radiation was investigated. Oral administration of CIE bestowed a survival advantage to mice exposed to lethal doses of gamma radiation. Radiation-induced depletion of the total blood count and bone marrow cellularity were prevented by treatment with CIE. Damage to the cellular DNA (as was evident from the comet assay and the micronucleus index) was also found to be decreased upon CIE administration...
