Land use of sewage sludge is the primary disposal method in Shanxi, accounting for 42.66% of all. To determine the ecological risk of heavy metals in sewage sludge, contents of seven heavy metals in sewage sludge from 9 municipal waste water treatment plants (WWTPs) that had the highest application for land use were determined. The order of the measured concentrations was: Zn > Cr > Cu > Ni > P...
The present study aimed to evaluate the health risk of heavy metals (iron, zinc, cadmium, arsenic, nickel, lead, and mercury), benzene, toluene, ethylbenzene and xylene (BTEX), and polycyclic aromatic hydrocarbons (PAHs) in the workplace in a secondary oil re-refining factory. In this descriptive, cross-sectional study, samples were collected and analyzed using the NIOSH 1501 method at eight sa...
Lynch syndrome (LS) is an autosomal-dominant inherited disorder mainly caused by a germline mutation in the DNA mismatch repair (MMR) genes (MLH1, MSH2, MSH6, and PMS2) and is associated with increased risk for various cancers, particularly colorectal cancer and endometrial cancer (EC). Women with LS account for 2% to 6% of EC patients; it is clinically important to identify LS in such individu...
We investigated the widespread belief that life gets better and better over time—as revealed in individuals’ “subjective trajectories” for life satisfaction (LS) derived from their ratings of recollected past, current, and anticipated future LS— among depressed (i.e., current major depressive disorder, fully remitted, partially remitted) and nondepressed groups using a two-wave longitudinal sam...
To determine whether release of tumor necrosis factor-a (TNF-a), a cytokine that affects iron homeostasis, may be selectively altered in hereditary hemochromatosis, we measured concentrations of TNF-a and interleukin-ls (IL-ls) in supernatants of cultured peripheral blood monocytes from 11 homozygotes for hereditary hemochromatosis, 11 healthy individuals, and five patients with iron-loading an...
Metals are ubiquitous within the earth crust. However, the exceptional high-level concentration of heavy metals in the soil due to natural or anthropogenic activities and the chemical forms in which they exist determine the level of risk they portend to the environment. This work was aimed at determining the background level of the presence of seven priority toxic metals (Cr, Ni, Pb, As, Cd, Cu...
Background Chronic inflammatory bowel disease (IBD) and Lynch syndrome (LS) are associated with an increased risk for developing colorectal cancer (CRC). After 8-10 years of pan-ulcerative colitis (DC), the risk of CRC is 2%, increasing by 0.5-1.0% annually. LS has been associated with a 60-80% lifetime risk of CRC. It is unclear whether individuals diagnosed with both IBD and LS would have a c...
hard gelatin capsule filled with acetaminophen, osmotic agent (sorbitol), a release promoter (sodium dodecyl sulfate), coated with a semipermeable cellulose acetate membrane containing a hydrophobic plasticizer (castor oil) and sealed with white bees wax plug was designed. when placed in the sink water penetrates the membrane, dissolves the osmotic agent and increases the osmotic pressure insid...
