Inhibition factor of ammonification in stored urine with fecal contamination
Water Science and Technology, 2008 Inhibition factors of urea hydrolysis caused by fecal contamination as source of urease were investigated. The urea hydrolysis was described by initial ammonification rate (IAR). Three factors for the inhibition (pH, free ammonia nitrogen (FAN) and salinity) were investigated in this study. It was found that the optimum pH value for the urea hydrolysis

Cutaneous Melanoma Drives Metabolic Changes in the Aged Bone Marrow Immune Microenvironment
Aging and Cancer, EarlyView.Melanoma, the deadliest form of skin cancer, increasingly affects older adults. Our study reveals that melanoma induces changes in iron and lipid levels in the bone marrow, impacting immune cell populations and increasing susceptibility to ferroptosis.

Logging and forest decline effects on the surface humus horizons in the Šumava Mts.
Journal of Forest Science, 2006 Holorganic layers belong among the key ecosystem components of forest soils at higher altitudes. Increased biological activity of the surface humus is very often observed after forest decline and/or forest cut and removal at these sites.
