D-1 Gene Polymorphism in Salivary Gland Tumors

Objectives This study aimed to assess PD-1gene polymorphism in salivary gland tumors in patients referred to Khalili Hospital in Shiraz. Methods This case-control study evaluated 48 patients with salivary gland tumors and 100 age- and sex-matched healthy controls. First, 5cc blood samples were obtained from patients and transferred to vials containing anti-coagulated EDTA. DNA was extracted, a...

Indication of Gene Amplification in Rhynchosciara by Rna-dna Hybridization

nism of cell differentiation was recently demonstrated in the case of ribosomal RNA cistrons of amphibian oocytes (1-3), and it seems that this phenomenon is of widespread occurrence (4) . In somatic cells the evidence for amplification thus far is based on cytological observations . The best known cases are those of Rhynchosciara and Sciara ; in the prepupal phase of these insects, it was poss...

Formation of Salivary Secretion in Rhynchosciara Americana

INTRODUCTION Since the genus Rhynchosciara belongs, like Chironomus, to the suborder Nematocera it will be very interesting to see if the formation of its salivary secretion proteins is similar to that of Chironomus secretion or to Bombyx silk biosynthesis . Moreover, this work will be of importance for a better understanding of the hemolymph protein function and will provide a basis for improv...

Structure and Arrangement of Salivary Gland Chromosomes in Drosophila Species.

goes a profound change in electronic structure on attachment to hemoglobin. The magnetic susceptibility of hemoglobin itself (ferrohemoglobin) corresponds to an effective magnetic moment of 5.46 Bohr magnetons per heme, calculated for independent hemes. This shows the presence of four unpaired electrons per heme, and indicates that the heme-heme interaction tends to stabilize to some extent the...
