Cytokine and eicosanoid profiles of phosphate mine workers

Th1 and Th2 Cytokine Profiles in Malignant Pleural Effusion

Background: The alteration of Th1 and Th2 cytokine levels is the subject of controversy in pleural effusions caused by malignancy, a situation that favors a Th2 immune response. Objective: To examine the different levels of IL-4 and IL-10 (Th2 cytokines), and IL-2 and interferon-γ (IFN-γ) (Th1 cytokines) in malignant and non-malignant pleural effusions. Method: The cytokine levels in pleural fl...

Occupational exposure of phosphate mine workers: airborne radioactivity measurements and dose assessment.

Under the Egyptian program for radiation safety and control, airborne radioactivity measurements and radiological dose assessment were conducted in some phosphate and uranium mines. Abu-Tartor mine is one of the biggest underground phosphate mines in Egypt. Airborne radioactivity, radon ((222)Rn) and its short-lived decay products (progenies) and thoron ((220)Rn), were measured in selected loca...

Fungal Infection Alters Phosphate Level and Phosphatase Profiles in Arabidopsis

Phosphorus (P), in the form of phosphate ion (Pi), is a vital element contributing in biomolecule structures, metabolic reactions, signaling pathways and energy transfer within the living cells. The objective of the present study was to assess the influence of fungal infection on Pi metabolism in compare to the effects of phosphate stress in Arabidopsis. Quantification of total P contents showe...

Cytokine and eicosanoid regulation by Schistosoma mansoniduring LSE penetration

Cercarial penetration, in low to moderate numbers, does not cause a normal skin inflammatory response; therefore, the authors sought to determine whether cercariae can down-regulate keratinocyte activation and thus the secretion of pro-inflammatory cytokines and eicosanoids. Human living skin equivalent (LSE, Organogenesis) consisting of dermal, epidermal and stratum corneum-like layers was use...
