The incorporation of 3H-arginine by the nucleus of the rat spermatid was studied with electron microscopic autoradiography. The nucleus is slightly labelled with 3H-arginine until step 9 of spermiogenesis, where
The blood–nerve barrier: enzymes, transporters and receptors—a comparison with the blood–brain barrier Ultrastructural localization ofalkaline phosphatasein rat cortical (A) and pial (B)microvessels. The luminal endothelial cell surfaces (arrowheads) show dense labelling while the abluminal surfaces (...
We studied the incorporation of 1+C-formate into uric acid and allantoin in different organs (liver, lung, kidney, spleen), isolated hepatocytes, perfused liver and urine of the rat. Allantoin had a higher specific radioactivity than uric acid after 14C-tbmriate load in the liver in vivo. ...
Tamil is the oldest language spoken in Tamil Nadu, India, with inscriptions dating back to the third century BCE found in caves, temples, and archaeological sites. The style and content of these inscriptions have evolved over time, reflecting changes in
Interleukin-1α is a suggested dual-function cytokine that diverged from interleukin-1β in mammals potentially by acquiring additional biological roles that relate to highly conserved regions in the pro-domain of interleukin-1α, including a nuclear localisation sequence and histone acetyltransferase-bind...

Affinity labelling of the digitalis receptor has indicated that it is situated on the N-terminal part of the a-subunit of the (Na+,K+)ATPase. Biochemical and pharmacological properties of the (Na+,K+)ATPase studied on intact chick embryonic hearts and under heart cell culture conditions have...
Plasma membranes from rat mammary gland containing a high concentration of [3H]oxytocin binding sites (2.8 pmol/mg protein) were used for photoaffinity labelling experiments. Competitive binding experiments show that these receptors bind with high affinity the specific oxytocin agonist [Thr4, Sar7]oxyt...
cation formation. Simply changing the geometry or substituents in the vinylic system, and/or the medium and/or thenucleophilebeing employed may be sufficient to divert the course of the reaction from the SN1/E1 pathways <69APO(7)1,71ACR73>. Some of the principle pathways will now be ...
