The unfolded protein response (UPR) is an adaptive response to the stress that is caused by an accumulation of misfolded proteins in the lumen of the endoplasmic reticulum (ER). It is an important component of cellular homeostasis. During ER stress, the UPR increases the protein-folding capacity of the endoplasmic reticulum to relieve the stress. Failure to recover leads to apoptosis. Specific cellular...
Understanding the cellular pathways that regulate angiogenesis during hypoxia is a necessary aspect in the development of novel treatments for cardiovascular disorders. Although the pathways of angiogenesis have been extensively studied, there is limited information on the role of miRNAs in this process. miRNAs or their antagomirs could be used in future therapeutic approaches to regulate hypoxia-induced...
The aim of the study was to analyze the significance of insects as pollinators of medicinal plants species occurring in natural state in Poland territory (some of them are also cultivated). Polish botanical database: Flora ojczysta 2004 was used as an analytical tool. Paper includes brief description of selected flower features connected with pollination by insects and their frequency in analyzed...
Solid Phase Microextraction (SPME) is used as a quick and easy alternative to standard distillation in essential oils composition assays. Due to the absence of the distillation step a considerable reduction of sample volume and of the time of sample preparation is possible. This method was used in experiments with essential oils obtained from Crithmum maritimum L. and Centella asiatica Urban (= Hydrocotyle...
