Workers in the zinc processing, for example, welding or hot-dip galvanizing, are exposed to aerosols consisting of particles and gases, including zinc oxide (ZnO), which can affect human health. In this study, we addressed the effects of short-term controlled exposure to nano-sized ZnO on the airway inflammatory markers in healthy volunteers. To this end, we determined the influence of ZnO inhalation on the content of zinc and biomarkers (leukotriene B4 (LTB4), peptide leukotrienes (LTC4/D4/E4), 8-iso-PGF2α, pH, and prostaglandin E2 (PGE2)) in exhaled breath condensate (EBC). MIK665 Sixteen non-smoking subjects (8 females, 8 men) were exposed to filtered air (sham) or ZnO nanoparticles (0.5, 1.0, and 2.0 mg/m3) for 4 h. EBC samples were collected according to specific study design. We found that the peptide leukotrienes were below the limit of quantification (LOQ) in all the EBC samples. ZnO exposure showed no detectable effect on any other parameters investigated when comparing the two groups. The content of Zn in EBC was unaffected by ZnO inhalation at any concentration used. Therefore, we conclude that the evaluation of Zn and biomarker content in EBC would not be a suitable way to assess the exposure to inhaled ZnO.
Statins are inhibitors of 3-hydroxy-3-methyl glutaryl coenzyme A (HMG-CoA) reductase, which is involved in cholesterol synthesis. The major side effects of statins include muscle- and liver-related toxicity. Muscle toxicity is highly associated with polymorphisms in cytochrome P450 proteins (CYPs), as predicted by pharmacogenomics. However, the mechanisms of hepatotoxicity are not well understood. Due to differences in cholesterol metabolism, statins are well tolerated in mice. In contrast, hamsters exhibit metabolic traits similar to humans and are suitable for studying the hepatotoxicity of statins.

We investigated the effect of rosuvastatin (RSV) on liver damage in wild-type (WT) hamsters fed a high-cholesterol diet (HCD) and LDLR knockout (LDLR
) hamsters that developed spontaneous hypercholesterolemia. Two cohorts of clinical subjects (clinical registry number 2017001) taking atorvastatin (ATV) were recruited for direct (assessment of cholesterol intake individually, n = 44) and indirect (celebratory meals/holiday season, n = 1993) examination of dietary cholesterol intake and liver damage, as indicated by elevation of alanine aminotransferase (ALT).

RSV at a dose of 10mg/kg caused fatal liver damage only in HCD-fed WT hamsters, while LDLR
hamsters with the same cholesterol levels were resistant to this toxic effect. In the human studies, we observed that the incidence of hepatic toxicity in patients receiving long-term ATV treatment was higher in patients with greater dietary cholesterol intake and in patients who consumed more food during Chinese holidays.

Our results propose, for the first time, that dietary cholesterol significantly contributes to statin-related hepatotoxicity, providing valuable insight into the clinical use of statins.

Pharmacological modulation of parasympathetic activity with donepezil, an acetylcholinesterase inhibitor, improves the long-term survival of rats with chronic heart failure (CHF) after myocardial infarction (MI). However, its mechanism is not well understood. The α7-nicotinic acetylcholine receptor (α7-nAChR) reportedly plays an important role in the cholinergic anti-inflammatory pathway. The purpose of this study was to examine whether blockade of α7-nAChR, either centrally or peripherally, affects cardioprotection by donepezil during CHF.

One-week post-MI, the surviving rats were implanted with an electrocardiogram or blood pressure transmitter to monitor hemodynamics continuously. Seven days after implantation, the MI rats (n = 74) were administered donepezil in drinking water or were untreated (UT). Donepezil-treated MI rats were randomly assigned to the following four groups peripheral infusion of saline (SPDT) or an α7-nAChR antagonist methyllycaconitine (α7PDT), and brain infusion of saline (SBDT) ntral blockade did not. This suggests that peripheral activation of α7-nAChR plays an important role in cholinergic pharmacotherapy for CHF.
To study attitudes to dental visits in a child population attending public dental health care between 1973 and 2013.

Random samples of individuals aged 3, 5, 10, 15 and 20years took part in cross-sectional studies based on clinical parameters and a questionnaire, all repeated every 10years using the same study design. One question related to dental attitude; "What do you feel at the prospect of an appointment with a dentist?". The affirmative answers were full of expectation, unaffected, ill at ease, frightened and sick, representing positive, neutral and negative attitudes. During the same 40-year period, a dental health care system based on prevention and regular dental appointments was reinforced.

In preschool children, the most pronounced change was an increase in the number of children reporting full of expectation during the study period. In 10-, 15- and 20-year-olds, there was an increase in unaffected and a decrease in ill at ease over time. A reduction in frightened was only seen in the 20-year-olds.

Despite a simultaneous dramatic decline in caries and a reduced need for operative dental treatment, the dental attitudes were fairly constant during the 40-year period. The moderate shifts to more positive or neutral dental attitudes were merely seen during the first 10 or 20years. After this, the changes in answers were limited. This leads to the assumption that factors other than dental treatment experiences have an impact on dental attitudes in children.
