Intraduodenal nutrient infusions cause an inhibition of antral motility and an increase in pyloric motility. The involvement of gastric myoelectrical activity in this intestinogastric feedback was studied. Electrogastrography and antropyloroduodenal manometry were performed in 10 healthy volunteers. The effects of 20-min infusions of 25% glucose (4 kcal/min) and saline were compared. Intraduode...

Biosynthetic incorporation of labeled amino acids into the major gastrins in rat antrum, Component I, gastrin 34 ("big" gastrin), and gastrin 17-like peptides ("little" gastrin) was demonstrated after in vitro incubation of antral mucosal slices. The antral gastrin synthesis was stimulated by fundectomy, which ablates gastric acid secretion and thereby increases the gastrin concentration in pla...

The Vaccinia-related kinase 1(VRK1), which is generally implicated in modulating cell cycle, plays important roles in mammalian gametogenesis. Female infertility in VRK1-deficient mice was reported to be caused by defective meiotic progression in oocyte at postovulatory stage. VRK1 roles in folliculogenesis, however, remain largely unknown. Here, accurate quantification of folliculogenesis is p...

OBJECTIVE The objective of this study is to present patients with sinus augmentation in the presence of an antral pseudocyst and the surgical procedure, complications, and outcome. STUDY DESIGN From 2002 to 2005, 109 patients were scheduled for 1- or 2-stage maxillary sinus floor augmentation (n = 129) because of inadequate alveolar bone height for implant placement. Radiographically, a signi...

Maxillary antrolith is a mineralized mass found very rarely in the maxillary sinus formed by exogenous or endogenous origin [1,2]. These mineralized bodies have been variously described as rhinoliths, antral rhinoliths, antral stones, antral calculi, antroliths, sinoliths, maxillary sinus stones and antrorhinoliths. The maxillary sinus is covered by ciliated pseudostratified columnar epithelium...

In women, ovary and adrenal gland produce androgens. Androgens are essential drivers of the primordial to antral follicle development, prior to serving as substrate for estrogen production in the later stages of folliculogenesis. Androgens play a crucial role in the follicular– stromal intertalk by fine tuning the extracellular matrix and vessel content of the ovarian stroma. Local auto-and par...

BACKGROUND Whether salpingectomy affects ovarian function is controversial. In this study, ovarian function was assessed by antral follicle count, ovarian volume and ovarian stromal blood flow measured by three-dimensional (3D) power Doppler ultrasonography. The objectives of the study were to compare the ovarian function of the operated side with the non-operated side after unilateral salpinge...

Authors report the case of a 51-year-old man, presenting with epigastralgia of recent onset. Physical exam was unremarkable. Endoscopy revealed a large, ulcerated, submucosal, antral tumor. CT scan reveals an antral mass with fat attenuation. The patient underwent a total gastrectomy. Macroscopic examination identified in the antral wall a 9-cm, well-circumscribed, nodular lesion, with a yellow...
