Secretory iga is the main immunoglobulin in secretions. (lecturio.com)

Thirteenth-century Latin alchemists, for whom the De aluminibus et salibus was one of the main reference works, were fascinated by the chlorinating properties of corrosive sublimate, and they soon discovered that when the metals are eliminated from the process of heating vitriols, alums, and salts, strong mineral acids can directly be distilled.

This is due to decrease in the concentration of uric acid and its salts in body fluids and urine, which helps dissolve existing uric acid deposits and prevents their formation in tissues and kidney. (medicatione.com)

7] Gastric carcinoids (type 2 carcinoids) occur almost exclusively in patients with MEN-1 who have Zollinger-Ellison syndrome (21-30% of patients with MEN-1) and can be malignant in 10-30% of cases. (medscape.com)

[4] This close relationship to the stem cell region suggests that Paneth cells are important in defending the gland stem cells from microbial damage, [4] although their function is not entirely known. (handwiki.org)

Alur - Pharmacological action Alur is a medication that violates the synthesis of uric acid. (medicatione.com)

Therefore, we propose that damage to and subsequent release of mtDNA elicits a protective signalling response that enhances nDNA repair in cells and tissues, suggesting that mtDNA is a genotoxic stress sentinel. (regenerativemedicine.net)

[2] Furthermore, among the four aforementioned intestinal cell lineages, Paneth cells live the longest (approximately 57 days). (handwiki.org)
