In the present study a solid-phase radioimmune assay was used for the demonstration of herpes simplex virus-specific IgG and secretory IgA antibodies in the lacrimal fluid from patients with active recurrent herpes keratitis. The method was quantitative and made it possible to test specifically for the production of secretory IgA antibodies produced during an active herpes simplex virus infecti...

– We examined the histology, histochemistry, and ultrastructure of Rathke’s glands in hatchlings of the three-toed box turtle, Terrapene carolina triunguis, and the desert box turtle, Terrapene ornata luteola. Both species possess one pair (axillary) of Rathke’s glands, which are similar anatomically and histochemically to one another. Each gland is composed of a single, highly vascularized sec...

The mechanism of secretory-vesicle formation from the trans-Golgi network (TGN) of endocrine cells is poorly understood. To identify cytosolic activities that facilitate the formation and fission of nascent secretory vesicles, we treated permeabilized pituitary GH3 cells with high salt to remove endogenous budding factors. Using this cell preparation, secretory-vesicle budding from the TGN requ...

The exocrine protein rat anionic trypsinogen has been expressed and is secreted from the murine anterior pituitary tumor cell line AtT-20. We examined which secretory pathway trypsinogen takes to the surface of this endocrine-derived cell line. The "constitutive" pathway externalizes proteins rapidly and in the absence of an external stimulus. In the alternate, "regulated" pathway, proteins are...

Alteration in the release of female steroid hormones like progesterone and estrogen a systematic manner is due to periodic ovarian variation. The alteration causes physiological cardiovascular activities ultimately affects Electrocardiogram (ECG) parameters. : To analyze heart rate changes PR interval duration ST segment ECG during menstrual phases. investigate any change rate, different phases...

A study on leaf anatomical characteristics was undertaken three medicinal plants species, Eclipta prostrata (L.) L., Vernonia amygdalina Delile and Clitoria ternatea L. It is found that there are variables in epidermal features such as anticlinal wall patterns, stomata types, trichome the occurrence of secretory structures. Results showed slight variation which is, sinuous abaxial surfaces stra...

BACKGROUND The current understanding of hormonal regulation of matrix metalloproteinase-26 (MMP-26) in the primate endometrium is incomplete. The goal of this work was to clarify estrogen and progesterone regulation of MMP-26 in the endometrium of ovariectomized, hormone-treated rhesus macaques. METHODS Ovariectomized rhesus macaques (n= 66) were treated with estradiol (E(2)), E(2) plus proge...

Dr. Russel J. Reiter was awarded his fifth honorary title by the National University of Cuyo, Argentina, for exemplary contributions towards unraveling mysteries pineal gland and, importantly, its major secretory product, melatonin. This commentary provides a glimpse accomplishments and summary speech during ceremony.
