Tough Sprouting – Impact of Cadmium on Physiological State and Germination Rate of Soybean Seeds

Acta Societatis Botanicorum Poloniae, 2020
Seed germination is the earliest process in plant development and is crucial for further plant growth and fitness. The process is regulated by various internal and external factors, including soil pollutants such as nonessential metals.

Tethering of vesicles to the Golgi by GMAP210 controls LAT delivery to the immune synapse

Nature Communications, 2019
The immune synapse at the interface between T cells and antigen-presenting cells manifests intense vesicular trafficking, but how the vesicles are sorted is still unclear.

Neutron activation analysis of multimetallic accumulation in dolomites [PDF]

Hemijska Industrija, 2008
The reason for exploring polymetallic ores, which are found in dolomite structures of the Veovača and Borovica zone near Vareš, lies in the fact that there is very little information about its chemical structure.
