Canine lacrimal and third eyelid superficial glands’ macroscopic and morphometric characteristics Ciência Rural
Cabral,Vânia Pais; Laus,José Luiz; Dagli,Maria Lúcia Zaidan; Pereira,Gener Tadeu; Talieri,Ivia Carmem; Monteiro,Eduardo Raposo; Mamede,Fabrício Villela.
The lacrimal and third eyelid superficial glands produce the aqueous component of the preocular tear film. In this research, morphologic and morphometric assessments of the parenchyma and stroma of both lacrimal glands of healthy adult mongrel dogs were performed. Both lacrimal and third eyelid glands of fourteen dogs were collected, summing fifty-six samples. The macroscopic and morphometric data were statistically analyzed, according to the glandular type (lacrimal and third eyelid superficial glands) and sexual dimorphism (male or female). The lacrimal glands were significantly larger and longer than the superficial glands of the third eyelid. Expressive morphometric differences of interlobular duct, lymphocytic infiltration, interlobular vessels and...

TMEM16 proteins: the long awaited calcium-activated chloride channels? BJMBR
Flores,C.A.; Cid,L.P.; Sepúlveda,F.V.; Niemeyer,M.I..
Currents mediated by calcium-activated chloride channels (CaCCs), observed for the first time in Xenopus oocytes, have been recorded in many cells and tissues ranging from different types of neurons to epithelial and muscle cells. CaCCs play a role in the regulation of excitability in neurons including sensory receptors. In addition, they are crucial mediators of chloride movements in epithelial cells where their activity regulates electrolyte and fluid transport. The roles of CaCCs, particularly in epithelia, are briefly reviewed with emphasis on their function in secretory epithelia. The recent identification by three independent groups, using different strategies, of TMEM16A as the molecular counterpart of the CaCC is discussed. TMEM16A is part of a...
