It could be potential for the prevention of allergic inflammatory diseases in BMMCs.
Tamarixetin effectively decreased degranulation and the eicosanoid generation such as leukotriene C4 and prostaglandin D2 in BMMCs. To elucidate the mechanism involved, we investigated the effect of tamarixetin on the phosphorylation of signal molecules. Tamarixetin inhibited the phosphorylation of protein kinase B (Akt) and its downstream signal molecules including IκB kinase and nuclear factor-κB. Besides, tamarixetin downregulated the phosphorylation of cytosolic phospholipase A2 and p38 mitogen-activated protein kinase.Conclusion In summary, tamarixetin inhibits degranulation and eicosanoid generation through the phospholipase Cγ1 as well as Akt pathways. It could be potential for the prevention of allergic inflammatory diseases in BMMCs.The Saharan Air Layer is a mass of hot, dry air laden with dust that forms over the Sahara and moves towards the Atlantic Ocean. This air mass contains soil dust particles emitted by the action of winds on the African continent. Between June and August, the large-scale patterns of wind circulation transport dust from the Sahara across the tropical North Atlantic Ocean, affecting parts of the Caribbean, Central America, Mexico, even some regions of the United States, and the Mediterranean and Southern Europe. Between December and April, wind circulation patterns facilitate dust transportation from the Sahara to the northern parts of South America and the Amazon. This dust transportation a phenomenon of interest to geosciences and public health because of the potential health impacts of dust dispersion and circulation in the atmosphere. Thus, we assessed the relationship between exposure to Saharan dust (SahD) and its implications for human health in the Americas. We performed a nonsystematic review in the PubMed, Google Scholar, EMBASE, and Scielo databases of studies published between 2000 and 2020 in Portuguese, English, French, or Spanish using the search words "Saharan dust," or "mineral dust," or "desert dust," and "human health." The available direct air pollutants measurements indicate that the pollution level in the cities affected on a constant and prolonged basis is high versus acceptable standards. Further, this review also showed that the negative health effects of SahD are sparsely studied in the Americas.
Asthma diagnosis in children is occasionally challenging, and the issue of undiagnosed asthma before adolescence has been poorly studied in Japan. The present study was conducted to investigate the possible presence of undiagnosed asthma in the general population of children living in a rural area of Japan.
The participants comprised 120 fourth graders aged 9-10 years (boys/girls 63/57) attending five elementary schools in Yawatahama, Ehime, Japan. All the children underwent respiratory function tests and fraction of exhaled nitric oxide (FeNO) measurements. Based on the results of a questionnaire, the children were also categorized into groups depending on their allergic diseases.The authors assessed the results of both the respiratory function tests and the FeNO measurements for children who were classified into the nonallergic group.
A total of 76 (63%) children, who completed the tests appropriately, were included in the analysis. According to the report, among the 24 children in the nonallergic group, six (25%) showed abnormalities in respiratory tests. One had an abnormal % forced vital capacity (%FVC; <80%), three had abnormalities in both forced expiratory volume in 1 sec (FEV1)/FVC (<80%) and % maximal mid-expiratory flow (<65%), three had concave flow-volume curves, and one had a high FeNO measurement (41 ppb).
A certain proportion of Japanese elementary school children, categorized as having no allergy, showed respiratory function test abnormalities. A follow-up study is needed to determine the prognosis and outcomes of the children with these abnormalities.

We previously reported an increased prevalence of asthma among patients who had lived in temporary housing after the 2011 Great East Japan Earthquake. Vorinostat mw We investigated the prognosis of asthma in former residents of temporary housing after allergen avoidance.
Asthma was diagnosed in adults ≥ 15 years from 2014 to 2019 who had lived in temporary housing in Ishinomaki City for at least 1 year. The disease prognosis after the intervention of allergen avoidance in cases that were followed for more than 3 years during the 6-year study period was analyzed. We measured the
-specific immunoglobulin E (IgE) levels in serum, and the amount of Dermatophagoides group 1 (
1) antigen on their futons or mattresses. We instructed residents in an allergen avoidance strategy that included 32 tasks, including using microfiber bedding covers.
Of the 202 examinees who were followed for at least 3 years during the 6-year study period, 72(35.6%) were asthmatic during at least one examination. Of these 72 asthmatics, 55(76.4%) developed the disease after the earthquake, and more than half of the cases that we diagnosed at the examination were mild intermittent asthma. After the allergen-avoidance intervention, both the
1 level on the futons or mattresses of residents who were diagnosed with asthma but who were nonasthmatic at the final screening and their serum
-specific IgE levels significantly decreased (P < 0.01) at the final examination.
Antigen avoidance ameliorated mild asthma that was prevalent among residents of temporary housing after the earthquake.
