Ambrosia pollen contains strong allergens. Allergic reactions can also be caused by direct contact with the plant. The investigations of dynamics seasons were conducted in Lublin (Poland) and Ivano-Frankivsk (Ukraine) 2013–2015. onset end seasons, maximum concentrations, annual sums, number days an allergy risk determined. Additionally, types trichomes present on different parts artemisiifolia ...

The pancreatic B cell has been used as a model to compare the release of newly synthesized prohormone/hormone with that of stored hormone. Secretion of newly synthesized proinsulin/insulin (labeled with [3H]leucine during a 5-min pulse) and stored total immunoreactive insulin was monitored from isolated rat pancreatic islets at basal and stimulatory glucose concentrations over 180 min. By 180 m...

The secretory process in pituitary mammotrophs was analyzed by quantitative electron microscope autoradiography. Dispersed pituitary cells from estrogen-treated female rats were subjected to pulse-labeling with [3H]leucine (5 min) followed by a chase incubation of up to 4 h. Autoradiograms were prepared using fine-grained emulsion (Kodak 129-01), and analyzed using a three-step "mask analysis' ...

In human endometrium, cytokines and growth factors that vary periodically during the menstrual cycles have been suggested to play various roles in uterine function. In the present study, differential gene expression in human endometrium between the proliferative and the secretory phases was investigated by using a human cDNA expression array system. Human interleukin (IL)-15 was identified as a...

PLUNC (palate, lung and nasal epithelium clone)-associated gene originally referred to one gene, but now has been extended to represent a gene family that consists of a number of genes with peptide sequence homologies and predicted structural similarities. PLUNC-like proteins display sequence homology with BPI (bactericidal/permeability-increasing protein), a 456-residue cationic protein produc...

BACKGROUND The biological function of the Reg protein, a non-enzymic protein produced in fairly large amounts by pancreatic acinar cells, remains elusive. Its susceptibility to proteolysis leading to precipitation of the proteolysis product at neutral pH suggests that it could contribute to the protein plugging observed in cystic fibrosis (CF). AIMS To study its behaviour in the serum of CF p...
