Article Synopsis
- * A study using different levels of ozone concentration found decreased uptake of essential minerals like calcium, magnesium, iron, zinc, sodium, and potassium by roots, with specific differences in how these minerals were allocated between roots and shoots.
- * Although chronic ozone exposure influenced mineral uptake and distribution, it did not significantly change total carbon and nitrogen concentrations in leaves or roots, with only minor changes such as reduced lignin in leaves at the highest ozone level.
Due to climate change, sessile oak (Quercus petraea) seedlings experience an increasing risk of drought during regeneration of forest stands by management practices. The present study was aimed at elucidating the potential of sessile oak seedlings originating from sites with different aridity and nitrogen (N) supply to acclimate to contrasting water availability. For this purpose, a free-air cross-exchange experiment was conducted between a dry and a humid forest stand with high and low soil N contents, respectively, during two consecutive years differing in aridity before harvest.

The chemical oxidation of HCP by KMnO was performed to systematically evaluate the effects of oxidant dose, pH, temperature, typical anions, humic acid (HA), and various matrices on HCP removal. The second-order rate constant for HCP was determined to be 4.

The results showed that HCB coated on the surfaces of all AlO could be photodegraded rapidly, and Neutral-AlO presented the best performance. Meanwhile, the efficient removal of HCB in real water matrices, including tap water, river water and secondary clarifier effluent showed the potential practical application of AlO.

A deficiency of vitamin D in chronic hepatitis C (CHC) patients has been shown to be linked with the severity of liver fibrosis, but little is known about the mechanism of this association.
Objective: In this study, we evaluate the potential interrelation between vitamin D levels, oxidative stress, and apoptosis, based on liver fibrosis in geriatric patients infected with hepatitis C virus (HCV) genotype 4.
