Stabilized Criegee Intermediates (sCIs) have been identified as oxidants of atmospheric trace gases such as SO2, NO2, carboxylic acids or carbonyls. The atmospheric sCI concentrations, and accordingly their importance for trace gas oxidation, are controlled by the rate of the

Microcompartments are loose protein cages that encapsulate enzymes for particular bacterial metabolic pathways. These structures are thought to retain and perhaps concentrate pools of small, uncharged intermediates that would otherwise diffuse from the cell. In Salmonella enterica, a microcompartment encloses

Alcohol intoxication can increase inflammation and worsen injury, yet the mechanisms involved are not clear. We investigated whether acute alcohol intoxication increases microvascular permeability and investigated potential signaling mechanisms in endothelial cells that may be involved. Conscious rats received a

Electronic (e-)cigarettes have emerged in recent years as putative alternative to conventional tobacco cigarettes. These products do not contain typical carcinogens that are present in tobacco smoke, due to the lack of combustion. However, besides nicotine, hazards can also arise

Cigarette smoke (CS) exposes chemosensory nerves in the airways to a multitude of chemicals, some acting through the irritant receptors TRPV1 and TRPA1 but potentially also through nicotinic acetylcholine receptors (nAChR). Our aim was to characterize the differences in sensory

Our previous observation that NADP-dependent secondary alcohol dehydrogenase (ADH-1) is down-regulated in metronidazole-resistant Trichomonas vaginalis isolates prompted us to further characterise the enzyme. In addition to its canonical enzyme activity as a secondary alcohol dehydrogenase, a pronounced, so far unknown

Some of the effects of ethanol in the central nervous system are due to changes in function of ligand-gated ion channels. Production of detectable amounts of acetaldehyde, a primary metabolite of ethanol, has been demonstrated in brain homogenates. The aim

The Maillard reaction that leads to the formation of advanced glycation end-products (AGEs) plays an important role in the pathogenesis of angiopathy in diabetic patients, in aging and in neurodegenerative processes. We hypothesize that acetaldehyde (AA), one of the main

The present study was undertaken to investigate the mechanism by which adenosine receptors (ARs)-mediated the cAMP/PKA/CREB signal pathway regulates the activation of acetaldehyde-induced hepatic stellate cells (HSCs). Primary HSCs were isolated from SD rats, cultured in vitro, and activated with

In the course of analyzing blood samples from drunk drivers, several low molecular weight volatiles were occasionally identified in addition to ethanol on the gas chromatograms. Among 21, 153 blood specimens analyzed during 1986, 77 contained ethanol as well as

The cladodes of Opuntia ficus-indica (prickly pear cactus) have a low protein content; for use as a balanced feed, supplementation with other protein sources is therefore desirable. We investigated protein enrichment by cultivation of the yeasts Candida utilis and Kluyveromyces

Mammalian cells attempt to maintain their homeostasis under endoplasmic reticulum (ER) stress. If the stress cannot be alleviated, cells are led to apoptosis through induction of C/EBP homologous protein (CHOP). ER stress is provoked in osteoarthritis chondrocytes, and intracellular accumulation

Orange mint moths, Pyrausta orphisalis (Walker) (Crambidae), were initially trapped in a study of noctuid moth attraction to floral volatiles. A subsequent series of trapping experiments in commercial mint fields determined that phenylacetaldehyde and 4-oxoisophorone were attractive to P. orphisalis

Aldehyde dehydrogenase (ALDH2) and alcohol dehydrogenase (ADH) gene polymorphisms associating with enhanced acetaldehyde exposure and markedly increased cancer risk in alcohol drinkers provide undisputable evidence for acetaldehyde being a local carcinogen not only in esophageal but also in gastric cancer.

Recent electrophysiological evidence suggests that ethanol simultaneously exerts opposite effects on the activity of dopamine (DA) neurons in the ventral tegmental area (VTA) through two parallel mechanisms, one promoting and the other reducing the GABA release onto VTA DA neurons.
