Time and spatial trends of operated cryptorchidism in France and environmental hypotheses: a nationwide study from 2002 to 2014.

STUDY QUESTION: Is there an evolution in the risk of operated cryptorchidism in France and does local geographical environment appear as an … eterogeneity and 24 clusters (P < 0.0001) were detected. The main cluster was localized in a former coal mining and metallurgic area in northern France, currently an industrial area. The cluster analysis suggests the role of shared socio-economic and environmental factors that may be geographically determined and intertwined. The industrial activities …

COVID-19 Exposure Tracking Within Public Health & Safety Enterprises: Findings to Date & Opportunity for Further Research.

UNLABELLED: Where there is limited access to COVID-19 tests, or where the results of such tests have been delayed or even invalidated (e.g., California and Utah), there is a need for scalable alternative approaches-such as a heuristic model or "pregnancy test for COVID-19" that can factor in the time denominator (i.e., duration of symptoms). This paper asks whether infection among these public health and safety agencies is a "canary in the coal mine," litmus test, or microcosm (pick your analogy) for the communities in which they operate. Can COVID-19 infection counts and rates be seen "moving…

Air pollution.

Toxic air pollutants are continuously released into the air supply. Various pollutants come from chemical facilities and small businesses, such as automobile service stations and dry cleaning establishments. Others, such as nitrogen oxides, carbon monoxide and other volatile organic chemicals, arise primarily from the incomplete combustion of fossil fuels (coal and petroleum) and are emitted from sources that include car exhausts, home heating and industrial power plants. Pollutants in the atmosphere also result from photochemical transformations; for example, ozone is formed when molecular ox…

Coal stove heating remained the dominant exposure source but decreased from 94.1 to 89.8%, whereas charcoal hotpot-related poisoning increased from 4.2 to 9.1% (both P < 0.001). The overall severity profile showed a higher proportion of mild cases in the …

Methods of model calibration: observations from a mathematical model of cervical cancer.

Continuing with comparative genomic exploration of worldwide butterfly fauna, we use all protein-coding genes as they are retrieved from the whole genome shotgun sequences for phylogeny construction. Analysis of these genome-scale phylogenies projected onto the taxonomic classification and the knowledge about butterfly phenotypes suggests further refinements of butterfly taxonomy that are presented here. As a general rule, we assign most prominent clades of similar genetic differentiation to the same taxonomic rank, and use criteria based on relative population diversification and the extent o

Environmental particulate-mediated cytokine production in lung epithelial cells (A549): role of preexisting inflammation and oxidant stress.

Epidemiologic data show that air pollution particulates cause adverse pulmonary health effects, especially in individuals with preexisting lung disease. We sought to model in vitro preexisting lung inflammation in order to investigate the hypothesis that "primed" lung epithelial cells will exhibit enhanced phlogistic responses [e.g., interleukin-8 (IL-8) production] to particulate air pollution. Exposure of tumor necrosis factor alpha (TNF-alpha) primed or control A549 cells to the air pollution particulates, residual oil fly ash (ROFA), and the known pathogenic dust alpha-quartz, but not iner

Research progress on arsenic, arsenic-containing medicinal materials, and arsenic-containing preparations: clinical application, pharmacological effects, and toxicity.

Introduction: The toxicity of arsenic is widely recognized globally, mainly harming human health by polluting water, soil, and food. However, its formulations can also be used for the clinical treatment of diseases such as leukemia and tumors. Arsenic has been used as a drug in China for over 2,400 years, with examples such as the arsenic-containing drug realgar mentioned in Shennong's Herbal Classic. We have reviewed references on arsenic over the past thirty years and found that research has mainly focused on clinical, pharmacological, and toxicological aspects. Results and Discussion: The f

Residual oil fly ash inhalation in guinea pigs: influence of absorbate and glutathione depletion.

Inhaled urban particulate matter (PM) often contains metals that appear to contribute to its toxicity. These particles first make contact with a thin layer of epithelial lining fluid in the respiratory tract. Antioxidants present in this fluid and in cells might be important susceptibility factors in PM toxicity. We investigated the role of ascorbic acid (C) and glutathione (GSH) as determinants of susceptibility to inhaled residual oil fly ash (ROFA) in guinea pigs (male, Hartley). Guinea pigs were divided into four groups, +C+GSH, +C-GSH, -C+GSH, and -C-GSH, and exposed to clean air or ROFA

A Comparative Study of the Effectiveness and Safety of Topical Calcipotriol and Topical Methotrexate in Chronic Plaque Psoriasis.

Background Psoriasis is a papulosquamous disease with variable morphology, distribution, severity, and course. Chronic plaque psoriasis, or psoriasis vulgaris, is the most common form of psoriasis. Present available preparations for mild to moderate chronic plaque psoriasis for topical use are local corticosteroids, coal tar, dithranol, tazarotene, calcipotriol, tapinarof, and calcineurin inhibitors. However, every preparation has its disadvantages. Calcipotriol, an active form of vitamin D, is available in topical form for dermatological use. Chronic plaque psoriasis is the chief medical use …
