Specimens were collected in reproductive and nonreproductive condition throughout the year and five ultrastructurally unique regions were recognized: the anterior infundibulum, posterior infundibulum, glandular uterus, nonglandular uterus, and vagina. Except for the anterior infundibulum and vagina, which exhibit no seasonal variation in ultrastructure, the oviduct becomes highly secretory at the start of vitellogenesis. This includes the entire luminal border of the uterus, the tubular glands of the glandular uterus, and the luminal border and sperm storage tubules of the posterior infundibulum.

Careful examination of archival material showed that although most small p53 patches arise interfollicularly, some may actually arise high up in a follicle, in the infundibulum..
Failure to recognize the impact that MSH has on the position of the ethmoid infundibulum relative to the medial orbital wall could lead to inadvertent damage to the wall during surgery. We then correlated the relationship of the ethmoid infundibulum to the medial orbital wall as determined by computed tomography in patients with and without MSH. We found that in most cases of MSH, the ethmoid infundibulum was displaced lateral to the medial wall of the orbit; the correlation between MSH status and displacement was statistically significant (p < 0.05).
Only the left oviduct is developed as a long tube with a length of 122 +/- 23.1 cm, and is subdivided into infundibulum (15.2 +/- 4.0 cm), magnum (63.3 +/- 9.4 cm), isthmus (5.6 +/- 3.1 cm), uterus (16.0 +/- 4.2 cm) and vagina (11.5 +/- 1.4 cm). The infundibulum part presents a cranial opening with thin and long fimbriae with few tubular glands in caudal tubular portion.

Granular cell tumours (GCT) and pituicytomas are rare tumours seen in the sellar suprasellar region which are believed to arise from either the infundibulum or the posterior lobe of the pituitary gland.
Immunofluorescent and immunoelectron-microscopic observations revealed that chalazae and chalaziferous layers overlaid to approximately 40 microm upon the vitelline membrane of the ovum were composed of the same materials as those produced by both types of secretory cells in the luminal and glandular epithelia at the infundibulum. We propose that the mechanism of chalaza formation is as follows: (1) chalazae first appear as fine filaments at the presumptive sharp and blunt ends of the ovum at the infundibulum; (2) these filaments are twisted into a lead fiber while the ovum is rotating and descending in the magnum; (3) at the posterior end of the magnum, the lead fiber is anchored to the thick egg white and lifted outward with the chalaziferous sublayers when the inner egg white is liquefied by absorbing water; (4) the lead fiber and chalaziferous sublayers are twisted further into the chalaza in the uterus..
Upon copulation in female Agkistrodon piscivorus, sperm migrate up the oviduct to sperm storage tubules (SSTs) in the posterior infundibulum. The epithelium of the SSTs is composed of ciliated and secretory cells and differs ultrastructurally from that of the epithelium lining the lumen of the posterior infundibulum.
With 3864 +/- 605 microm and 580 +/- 84 microm in THF compared to 646 +/- 140 microm and 225 +/- 34 microm in VHF, the total length and the length of the infundibulum differed significantly as determined by paired t-test (P < 0.0001).

In this study, the presence of cells of the oviductal epithelium in the serosa of the infundibulum and the ampulla, as well as indications of a high functional activity of the mesothelial cells in the areas studied were two aspects that differed from the findings of previous works.
We present a case of progressive unilateral MSH, which has an open ethmoid infundibulum and also presence of an open accessory ostium on the same side.
The so-called tendon of the infundibulum has previously been described as part of this skeleton, but its structure and incidence remain ill defined. In our opinion, therefore, accounts in the literature describing the "tendon of the infundibulum" as a tendinous structure connecting the aortic and pulmonary roots do not accurately represent this anatomical structure..
Investigations revealed the presence of thickened pericardium and a thickened calcific constrictive band around the atrioventricular groove posteriorly and over the infundibulum anteriorly.
Right ventriculogram showed a tripartite right ventricle, vasiform infundibulum, and membranous pulmonary valve atresia without ventriculocoronary connections.
KiSS-1 mRNA is readily detectable in oviduct samples from all phases of the estrous cycle, whereas kisspeptin-IR is detected in rat oviduct with a regionalized pattern of distribution, viz., strong expression in the isthmus, faint signals in the proximal ampulla, and a lack of immunostaining in the fimbriated infundibulum and interstitial portion.
The lower infundibulopelvic angle (LIPA) was measured as the angle between the vertical pelvis axis and the vertical axis of lower infundibulum (Sampaio's method). However, there was a significant difference between mean lower pole infundibulum length (P = 0.001), infundibulum width (P = 0.001) and LIPA (P = 0.0001) between stone-free patients and patients with residual fragments. Multivariate logistic regression analysis accepting stone-free as the favourable result also confirmed that LIPA, lower pole infundibulum length and width were factors that significantly affected the outcome.
Diffuse swelling of the infundibulum as well as lack of T1-hyperintense signal in the posterior lobe was noted by pituitary magnetic resonance imaging.

The results were correlated with the following anatomic parameters of the collecting system as determined from the pretreatment intravenous urography: (1) lower infundibulum width, (2) lower infundibulum length, (3) infundibulopelvic angle, (4) volume of the collecting system. Stone-free patients compared with patients having residual fragments had no significant differences in infundibulum width, infundibulum length, infundibulopelvic angle, or collecting system volume.

The outflow tract myocardium, subsequently, shortens as a result of ventricularization, contributing to the trabeculated free wall, as well as the infundibulum, of the right ventricle.
The infundibulum and magnum of the oviduct were examined in hens in full lay which were infected with two Australian strains of infectious bronchitis virus (IBV). The ultramicroscopic changes in the infundibulum and magnum were compared with control hens which had eggs at different positions in the oviduct. Between 16 and 24 days p.i., there was no cilia loss and lymphoid nodules were observed in the muscularis layer of the infundibulum and magnum of some hens from both infected groups. The magnum was more affected than the infundibulum. Cellular changes were more severe in the infundibulum and magnum of T-infected hens as compared to N1/88-infected hens. Loss of cilia in both the infundibulum and magnum pose a potential threat of secondary bacterial infection and also may affect fertility in breeder hens..

ERalpha in the connective tissue was more abundant at the infundibulum and ampulla, regardless of the phase of the estrous cycle and of E(2) and P(4) circulating concentrations.
Immediately after slaughter, oviductal samples of three different segments (isthmus, ampulla and infundibulum) were fixed, embedded in plastic resin and stained with toluidine blue or cryofixed and stored in a freezer at -70 degrees C until analysed by immunohistochemistry (pre-ovulatory inseminated sows) with an avidin-biotin peroxidase method. The numbers of intraepithelial lymphocytes of all sows as well as CD2- and CD3-positive cells of the pre-ovulatory inseminated sows were higher in the infundibulum than in the other segments (p < or = 0.001). In the subepithelial connective tissue of the pre-ovulatory inseminated sows, significantly higher numbers of lymphocytes (p < or = 0.001) and plasma cells (p < or = 0.001) were found in infundibulum than in isthmus. Neutrophils were found mainly in infundibulum, the number approximately 40 h after pre-ovulatory insemination was significantly higher (p < or = 0.05) than in the other groups and segments. In the subepithelial connective tissue of post-ovulatory inseminated sows, the numbers of lymphocytes was higher (p < or = 0.001) at day 19 than up to 50 h after insemination and lower (p < or = 0.001) in isthmus than in ampulla and infundibulum.

The "anatomic scenario" of this condition should be suspected for patients presenting with conditions such as empyema or mucocoele when there is a likelihood of stone impaction in the infundibulum of the gallbladder.
CK expression profile of DC was similar to follicular infundibulum and sebaceous gland. These results suggested that DC differentiates towards follicular infundibulum and mature sebaceous gland..
BACKGROUND: Hydrocalix is an uncommon condition that typically is treated with percutaneous dilation of the stenotic infundibulum. Of the remaining 11, the original infundibulum was dilated in all but one, in whom neoinfundibulotomy was performed with a laser.
CONCLUSION: Diffuse destruction of the complete pituitary gland including the infundibulum has to be considered in lymphocytic and granulomatous hypophysitis, whereas in xanthomatous, a circumscribed anterior pituitary lesion leading to compression of the pituitary gland without alteration of the pituitary stalk and optic chiasm can be assumed..
In combination with our own previous findings, which indicated an association between LOX stimulation and increased percentage of proinflammatory lipids in acne as well as a correlation between increased cytokine levels in the infundibulum, pilosebaceous duct hyperkeratinization, and augmented sebogenesis, the present data further support the involvement of lipid peroxides, in particular squalene peroxides, in establishing an inflammatory process in acne..

Increased stone diameter (P=0.0001) and burden (P=0.04) were found as the most significant factors that adversely affect the stone-free rate for pelvis renalis calculi, whereas an acutely oriented infundibulum and/or a long lower infundibulum (P=0.005) were unfavourable factors for clearance of lower caliceal stones. Increased stone burden, multiple stones, staghorn calculi, narrow lower infundibulopelvic angle and long lower infundibulum are factors that adversely affect the clearance rate..
We examined a new parameter: Renal longitudinal axis-infundibulum angle (RIA) for renal stone formation.
Magnetic resonance images showed incoherent pituitary stalk and re-review of the first computed tomography scans of the day of the accident confirmed hemorrhage in the infundibulum.
Hair follicle consists of 3 parts : the lower portion, from the base of the follicle including hair bulb to the insertion of the arrector pili muscle or buldge ; the isthmus, from the insertion of the arrector pili to the entrance of the sebaceous duct, and the infundibulum, from the entrance of the sebaceous duct to the follicular orifice.
Disseminated disease often involves the central nervous system, but only six isolated lesions in the infundibulum have been reported. Magnetic resonance imaging (MRI) of the brain showed a 1-cm homogeneously enhancing mass in the region of the infundibulum. The lesion, which was adherent to the infundibulum, was partially resected. CONCLUSIONS: Isolated Langerhans cell histiocytosis of the infundibulum is rare.
Cell fate analysis using the Tbx1 enhancer suggests that SHF-derived Tbx1-expressing cells contribute extensively to the right ventricular myocardium as well as the OFT during early development and ultimately give rise to the right ventricular infundibulum, pulmonary trunk, and pulmonary valves.
During the period between two consecutive ovipositions, the developing egg remained for 9h in the proximal part (infundibulum, magnum or isthmus) and for 39h in the distal part of the oviduct (uterus).
The oviductal infundibulum is an asymmetric funnel-shaped structure surrounding the ostium, in which a wide and a narrow side can be distinguished. Cyclical changes were observed in the infundibulum and ampulla, so that prominent and numerous ciliated cells lined apical areas of the folds in the follicular phase; whereas secretary cells were predominant throughout all areas of epithelial surface in the luteal phase.
Endocavitary investigations showed that the ventricular extrasystoles originated in the common ventricular myocardium (pulmonary infundibulum) in only 9 cases whereas the majority arose from the Parkinje system either on the anterior wall of the right ventricle or in septal region of the left ventricle. The extrasystoles arising from the Parkinje system and pulmonary infundibulum differed in their duration and polymorphism (128 +/- 18 ms vs 145 +/- 13 ms, p = 0.05; 3.3 +/- 2.7 morphologies vs 1.1 +/- 0.4, p < 0.001, respectively).
The septal arteries establish important relations with the pulmonary infundibulum but their contribution to its vascularization is negligible.
The follicular penetration processes are significantly influenced by the state of the follicular infundibulum; recent experimental investigations could demonstrate that it is essential to distinguish between open and closed hair follicles.
In cases in which the anomalous LAD crossed the obstructed infundibulum, thinning or coring of the endocardium was done.
Inlet and infundibulum right ventricular (RV) end-diastolic diameters reduced by 23+/-2% and 23+/-3%, respectively (p<0.001 for both measurements), although with a different time-course of changes.
The most cranial part of the right ventriculum infundibulum, the pulmonary anulus, the valve and finally the main trunk of the pulmonary artery are the most important structures.
RV morphology typical for ARVC was found discrete in one of them (bulges adipose tissue in the RV apex); the latter showed changes suggesting RV abnormality (mild segmental dilatation of infundibulum, adipose tissue in a free wall of the RV).
However, presumably because of a lack of certain hair keratins, the hair shafts that are generated twist and coil in the hair follicle infundibulum, which becomes dilated.
In the group of patients diagnosed with polyps pre-operatively, 97.4% had polyps originating in the anterior ethmoid complex, of which 89.7% had polyps originating in the anterior ethmoidal cells and over 60% had polyps specifically originating from each of the following sites: the uncinate or infundibulum, the posterior ethmoid sinus, the frontal recess and the face of the bulla ethmoidalis.
Here we describe the immunocytochemical mapping of SHBG-containing neurons and nerve fibers in the human hypothalamus and infundibulum. There were SHBG-immunoreactive axons in the median eminence and the infundibulum.
For this purpose, oviducts were collected from Landrace cycling sows and divided into three segments (isthmus, ampulla, infundibulum). Different concentrations of u-PA mRNA were detected in the three segments following the pattern isthmus>ampulla>infundibulum and this pattern was maintained during the oestrous cycle. On the contrary, the highest PAA was measured in the ampulla compared to the isthmus and the infundibulum and the highest ampullary PAA was detected during the first 2 days of the oestrous cycle.
Metastasic spread to the pituitary gland, specifically to the area of the infundibulum is, however, a more rare presentation.
Drainage of the frontal sinus to the middle meatus (medial to the superior attachment of the UP [ types 1-3]) was classified as group 1, and drainage of the frontal sinus to the ethmoid infundibulum (lateral to the superior attachment of the UP [ types 4-6]) was classified as group 2.
Seven helminth species were identified: two cestodes Choanotaenia infundibulum and Lyruterina nigropunctata, and five nematodes Aonchotheca caudinflata, Baruscapillaria obsignata, Eucoleus annulatus, Ascaridia galli and Heterakis gallinarum.
RESULTS: HALS was performed on three patients with MS type I and 2 with mimic MS owing to an unclear or abnormal anatomy, or an unusual circumstance in which an impacted stone was squeezed out from the infundibulum or the aberrant cystic duct impossible with laparoscopic approach.
Nuclei, which contained cells labeled for the androgen receptor (AR), were mainly identified in the olfactory bulbs, preoptic-septal region, infundibulum, amygdala, thalamus, tectum, torus semicircularis, and medulla.
The purpose of this research was to determine whether smoke solutions caused a change in adhesion between the OCC and infundibulum of the oviduct and to determine whether a change in adhesion could account for decreased OCC pickup rate.
Using immunohistochemistry, Ob-R-like positive reaction was observed only in the cytoplasm of secretory cells, having stronger intensity in the infundibulum and ampulla tracts than in the isthmus.
The anomalous artery arose from the same aortic sinus that gave rise to the main stem of the left coronary artery, and reached the right atrioventricular groove by traversing the tissue plane between the aortic root and the subpulmonary infundibulum.
Some patients with pulmonary atresia with an intact ventricular septum, mild to moderate right ventricular hypoplasia, and a patent infundibulum remain duct dependent on the flow of blood through the arterial duct despite adequate relief of the obstruction within the right ventricular outflow tract.
The connection between the nasopalatine infundibulum and the incisive fossa is typically closed at the time of birth.
A biopsy specimen obtained from a skin pustule showed subcorneal eosinophilic and neutrophilic pustules in the follicular infundibulum with marked spongiosis of the follicular epithelium.
We report a submicroscopic duplication of Xq27.1, the smallest reported to date (685.6 kb), in two siblings with variable hypopituitarism, callosal abnormalities, anterior pituitary hypoplasia (APH), an ectopic posterior pituitary (EPP), and an absent infundibulum. This duplication contains SOX3 and sequences corresponding to two transcripts of unknown function; only Sox3 is expressed in the infundibulum in mice. Next, we identified a novel seven-alanine expansion within a polyalanine tract in SOX3 in a family with panhypopituitarism in three male siblings with an absent infundibulum, severe APH, and EPP.
CASE: This 30-year-old woman had an accessory ovarian tumor attached to the infundibulum of the right fallopian tube which was solid and gross pathologically and microscopically showed the appearances of steroid cell tumor, NOS, a benign entity. CONCLUSION: We report the first case of an accessory ovarian steroid cell tumor, NOS, which attached to the infundibulum of fallopian tube..
Ebstein's malformation, tricuspid valvar dysplasia, and the presence or absence of the infundibulum, were especially noted. A patent infundibulum was noted in 34 of 39 specimens. The presence of a patent infundibulum confirms that atresia of the pulmonary valve is an acquired process.
The infundibulum was neither cannulated nor dilated.
Mean infundibulum width of hypophysis and transverse diameter of posterior hypophysis were significantly broader in patients with IHH than in controls (both having p < 0.001), while mean hypophysis height and volume did not differ between groups.
Taking into consideration the four factors that are currently incriminated in the development of acne, sebaceous hypersecretion, hyperkeratosis of the pilosebaceous infundibulum, bacterial colonisation and perifollicular inflammation, we have focused our study on a set of cells involved in the chronic inflammatory process.
The coronary artery branched into left and right arteries, with the left artery then coursing anomalously in the tissue plane between the aortic root and the subpulmonary infundibulum.
Reducing the tract size in pediatric cases, nonhydronephrotic systems and those with a narrow infundibulum, and secondary tracts in a multiple-tract procedure may also reduce blood loss during PCNL..
In the infundibulum, it was observed that the cysts, in the follicular phase, reduced Ricinus communis-I (RCA-I) and Ulex europaeus-I (UEA-I) binding. The Arachis hypogaea (PNA) binding in the infundibulum, during the luteal phase, decreased in the tube having adenomyosis.
Oviductal samples from three different parts (isthmus, ampulla and infundibulum), taken immediately after slaughter, were fixed, embedded in plastic resin and stained with toluidine blue or stored in a freezer at -70 degrees C until analysed by immunohistochemistry (prooestrus and anoestrus) with an avidin-biotin peroxidase method. During all stages, a lower degree of morphological changes (pseudostratification, mitosis and secretory granules) was found in the isthmus compared with ampulla and infundibulum. In ampulla and infundibulum, pseudostratification, mitotic activity and secretory granules of the epithelium were high at prooestrus/oestrus. Cytoplasmic protrusions of epithelial cells with some extruded nuclei were prominent in ampulla and infundibulum at all stages except for oestrus and early dioestrus. Numbers of CD2-positive cells did not differ between prooestrus and anoestrus while the numbers were significantly higher in the infundibulum than in ampulla and isthmus. Neutrophils were only occasionally found and mainly in the infundibulum. Higher numbers of plasma cells (p < or = 0.001) were found in infundibulum than in ampulla and isthmus. However, the number of neutrophils differed and were highest at prooestrus in ampulla and infundibulum. In the oviduct, the morphology differed in ampulla and infundibulum with oestrous cycle stages, which indicates an effect by ovarian steroid hormones. However, the immune cell infiltration (in the connective tissue) in the upper part, especially infundibulum, differed significantly from the one in the lower part, isthmus, indicating different immune functions within various parts of the oviduct..
Apart from findings described previously as being typical (e.g., dilation, hyperkeratosis, and spongiosis of infundibula), there were vacuolar alteration at the dermo-epithelial junction of infundibula, dyskeratotic cells scattered in infundibula, and parakeratosis in the manner of cornoid lamellation within an orthokeratotic plug filling a dilated infundibulum.
RESULTS: Nine abnormalities were identified including distal ureteral strictures (n = 4), vascular compression of the mid left ureter (n = 1), scarring of the mid right pole infundibulum (n = 1), bilateral hydronephrosis and hydroureter (n = 1), urinary reservoir calculus (n = 1), and tumor recurrence invading the afferent limb of the neobladder (n = 1).
In a 13 year-old boy exhibiting pulmonary hydatosis (first clinical signs 3 years earlier) echocardiography revealed a multi-compartmented cystic image of the anterior wall of the left atrium, with another similar image in the anterior section of the pulmonary infundibulum.
Half of the genital tract was divided into nine segments (cervix, corpus uteri, caudal, middle and cranial uterine horn (UTH), utero-tubal junction (UTJ), isthmus, ampulla and infundibulum), which were processed for histology and SEM.
The objective of the study reported here was to use scanning electron microscopy (SEM) to discover and describe the details of three-dimensional profiles and the natural (not surgically disturbed) topography/location of the infundibulum in the mouse. It will help new investigators to more quickly identify the infundibulum for successful transfer of microinjected eggs through a small opening into the oviduct/ampulla of pseudopregnant female mice for producing transgenic mice. Results of the study also illustrate the geographic orientation and natural topographic features of the ovary, infundibulum, ampulla, oviduct, and uterus. The presence of cilia on the surface of the crown foldings in the longitudinal section of the infundibular head stained with 1% toluidine blue provided direct evidence that evagination of the internal cilia of the infundibulum/oviduct results in formation of the infundibular crown. The new observation of the narrowing region of the infundibular head after surgical removal of the crown also suggests that formation of the infundibular crown may have resulted from the "evagination process" of internal cilia of the infundibulum/oviduct surface.
The pilosebaceous unit of the follicle is divided into three compartments: the infundibulum (superficial part, outlined by the sebaceous duct), the isthmus (between the sebaceous duct and arrector pili protuberance), and the inferior segment (stem and hair bulb).
In the second study, the reproductive tracts of 11 hens and 17 toms were aseptically excised, and the segments (female: vagina, shell gland, isthmus, magnum, and infundibulum; male: ductus deferens and testes) were swabbed with a dry cotton sterile swab. Of the 11 hens sampled, Campylobacter was isolated from the vagina (10/11), the shell gland (7/11), the isthmus (8/11), the magnum (6/11), and the infundibulum (4/11).
The estimation of PRL release in a test of stimulation with metoclopramide can be a sensitive (though not specific) test of dopaminergic activity in tuberous--infundibulum pathway and may be used to control the treatment..
The authors present a case in which a posterior communicating artery (PCoA) infundibulum progressed into an aneurysm in a patient with Alagille syndrome (arteriohepatic dysplasia). The 3-mm PCoA infundibulum had been noted on angiography studies obtained 5 years earlier, prior to clip occlusion of a basilar tip aneurysm. This case illustrates the small but growing number of examples of infundibulum progression.
Complex inferior calyceal calculi were defined as multiple calculi in two or more inferior calyces of the lower polar group, with each calyx draining through a separate infundibulum and at an acute angle to each other.
