BACKGROUND Cholinergic regulation of chronotropic (frequency) and inotropic (force) aspects of antral contractility and how these impact on gastric emptying are not well delineated. AIMS To determine the effects of cholinergic stimulation and inhibition on myoelectric, contractile, and emptying parameters of gastric motility. METHODS Ten normal subjects underwent three studies each, using s...

Intraluminal impedance recording has made it possible to record fluid transport across the pylorus during the interdigestive state without filling the stomach. During antral phase II, fluid transport occurs with and without manometrically detectable antral contraction. Our aim was to investigate the relationships between ultrasonographic patterns of antral contraction, manometric pressure waves...

background:   objective: the aim of this study was to evaluate the in vitro developmental competence of mouse vitrified pre-antral follicles in comparison to isolated pre-antral follicles derived from vitrified ovaries in the presence of alpha lipoic acid (ala).   materials and methods: pre-antral follicles derived from fresh, vitrified-warmed ovarian tissues and vitrified–warmed pre-antral fol...

Organ culture was used to compare gastrin and somatostatin release from cultured antral mucosa obtained from duodenal ulcer and non-ulcer (control) subjects. In response to dibutyryl cyclic AMP (DBCAMP) cultured antral mucosal explants from patients with a history of duodenal ulcer released a greater proportion of antral gastrin into the medium than did antral mucosal explants from non-ulcer su...

Background: Recent improvement in treatments of cancer has significantly increased survival rates of cancer patients. Unfortunately these treatments such as chemotherapy and radiotherapy can sever damage to the ovaries. Ovarian cryopreservation prior to chemo/ radiotherapy and auto-transplantation post-treatment can restore fertility to cancer patients. Hypoxia in the transplant from delayed re...

the aim of this study was to investigate the in vitro developmental competence of isolated pre-antral follicles derived from vitrified ovaries in the presence of coenzyme q 10 (coq 10 ) . mice pre-antral follicles derived from fresh and vitrified-warmed ovarian tissues were in vitro cultured individually in α-mem medium supplemented with or without coq 10 , followed by adding human chorionic go...

background: one of the most major obstacles of ovarian tissue vitrification is suboptimal developmental competence of follicles. matrix metalloproteinases 2 (mmp-2) and 9 (mmp-9) and their tissue inhibitors timp-1 and timp-2 are involved in the remodeling of the extracellular matrix in the ovaries. objective: this study aimed to evaluate the expression of mmp-2, mmp-9, timp-1, and timp-2 genes ...

oro-antral communication and fistula can occur as a result of inadequate and improper treatment. inadvertent communication with the maxillary sinus can occur during certain surgical procedures in the maxillary posterior region. though, spontaneous healing may occur in defects which are smaller than 2 mm but larger communications require immediate attention and should be treated without delay, i...

Mist1 was recently shown to identify a discrete population of stem cells within the isthmus of the oxyntic gland within the gastric corpus. Chief cells at the base of the gastric corpus also express Mist1. The relevance of Mist1 expression as a marker of specific cell populations within the antral glands of the distal stomach, however, is unknown. Using Mist1-CreERT mice, we revealed that Mist1...
