Fungal spores and mycelium fragments are particles which become and remain airborne and have been subjects of aerobiological studies. The presence and the abundance of taxa in aerobiological samples can be very variable and impaired by changeable climatic conditions. Because many fungi produce mycotoxins and both their mycelium fragments and spores are potential allergens, monitoring the presence of these taxa is of key importance. So far data on exposure and sensitization to fungal allergens are mainly based on the assessment of few, easily identifiable taxa and focused only on certain environments...

Gefitinib is an oral tyrosine kinase inhibitor targeting the epidermal growth factor receptor (EGFR) for non-small-cell lung cancer with EGFR mutations. Although a few studies have analyzed the causes of gefitinib-induced hepatotoxicity, research focusing on the time intervals before and after hepatotoxicity has yet to be reported. Therefore, this study investigated two types of factors: the time to reach gefitinib-induced hepatotoxicity and the time for recovery. From January 2013 to December 2014, a retrospective study was carried out on 473 non-small-cell lung cancer patients who were treated with gefitinib...

Solid fuels, such as coal, straw, and firewood are wildly used for cooking and heating in China, with the negative side effects of indoor air pollution and residential health problems. This article investigates the current and historical trend of China's disease burden caused by indoor air pollution (IAP) at the provincial level. The Global Burden Disease data set and national/provincial yearbooks are used. The results show the following: (1) In recent years, the burden of disease caused by IAP is decreasing; (2) in all health aspects, eastern coastal regions performed better than inland regions; (3) health risk is extremely severe in Henan, Sichuan, and Guizhou provinces; (4) IAP gives rise to serious diseases, including chronic obstructive respiratory diseases and cerebrovascular diseases...

Previous studies have shown that dogs are susceptible to influenza A viruses, and the close contact between dogs and humans poses a threat to public health. In 2015, a novel H3N8 influenza virus was isolated from a dog in eastern China. This strain was characterized by whole-genome sequencing with subsequent phylogenetic analysis and genetic comparison and found to be most closely related to avian influenza viruses co-circulating in China. It was able to replicate in mice without prior adaptation. The continued circulation of this novel H3N8 influenza virus in dogs could endanger other mammalian species...

The ocean's role in global climate change largely depends on its heat transport. Therefore, understanding the oceanic meridional heat transport (MHT) variability is a fundamental issue. Prevailing observational and modeling evidence suggests that MHT variability is primarily determined by the large-scale ocean circulation. Here, using new in situ observations in the eastern subpolar North Atlantic Ocean and an eddy-resolving numerical model, we show that energetic mesoscale eddies with horizontal scales of about 10-100 km profoundly modulate MHT variability on time scales from intra-seasonal to interannual...

The Kotschy's Gecko, Mediodactylus kotschyi, is a small gecko native to southeastern Europe and the Eastern Mediterranean. It displays great morphological variation with a large number of morphologically recognized subspecies. However, it has been suggested that it constitutes a species complex of several yet unrecognized species. In this study, we used multilocus sequence data (three mitochondrial and three nuclear gene fragments) to estimate the phylogenetic relationships of 129 populations covering a substantial part of the distribution range of the species...

BACKGROUND: Studies of a modified XELIRI (mXELIRI; capecitabine plus irinotecan) regimen suggest promising efficacy and tolerability profiles in the first-line and second-line settings. Therefore, we aimed to compare the efficacy and safety of the mXELIRI regimen with that of standard FOLFIRI (leucovorin, fluorouracil, and irinotecan), with or without bevacizumab in both regimens, as a second-line therapy for metastatic colorectal cancer. METHODS: We did a multicentre, open-label, randomised, non-inferiority, phase 3 trial...

BACKGROUND: Borrelia miyamotoi is a spirochete transmitted by several ixodid tick species. It causes a relapsing fever in humans and is currently considered as an emerging pathogen. In Europe, B. miyamotoi seems to occur at low prevalence in Ixodes ricinus ticks but has a wide distribution. Here we report the first detection of B. miyamotoi in Ixodes ricinus ticks collected in two independent studies conducted in 2016 in the north-eastern and north-western Alps, Italy. RESULTS: Three out of 405 nymphs (0...

BACKGROUND: Ehrlichia canis is a tick-borne bacterium that causes severe, life-threatening disease in dogs, being more prevalent in tropical and subtropical countries. Randomized studies conducted in Brazil indicate that the prevalence of E. canis infection in dogs ranges from 0.7% to over 50.0%. In a study conducted in northern Brazil, the prevalence was higher in dogs from urban areas, as compared to dogs from rural areas. In the present study, we investigated the exposure to Ehrlichia spp...
