The meaning of PERISTALSIS is successive waves of involuntary contraction passing along the walls of a hollow muscular structure (such as the esophagus or intestine) and forcing the contents onward.
(nutcracker esophagus), defined by a mean DCI of >5000mmHgscm, is not considered as abnormal in the last iteration of the Chicago classification. The relevance of this disorder is not widely accepted as it can be observed in asymptomatic subjects.12Provocative maneuvers such as multiple rapid ...
Ureteral dilation is also present in most cases, and if sufficient dilation is present, the ureter may be traced to the bladder or recognized near its insertion into the bladder. Hydronephrosis Hydronephrosis is defined as dilation of the renal collecting system secondary to obstruction. Obstruction ...
Continuous peristalsis was defined as a sequence of peristaltic contractions with a mutual distance between individual peristaltic waves of greater than or equal to 30 sec. A total of 81 episodes of reflux were recorded, of which 67 were preceded by peristaltic activity. Brief bursts of peristalsis...
A reflux episode was defined as starting when pH fell to less than 4 and ending when the pH rose to 5. When the rise to pH 5 took place in three or more discrete steps after motor responses to , the pH steps were labelled as initial change (I), middle changes (M), and last ...
(pixel change) of the midguts from the videos recorded. This software defines activity as the percentage of pixels that have changed in the entire defined arena between the current image and previous image. The videos are recorded in 2464 × 2056 resolution and the arena is set to be ...
An attempt is made to investigate the peristaltic motion of a Giesekus fluid in a planar channel under long wavelength and low Reynolds number approximations. Under these assumptions, the flow problem is modelled as a second-order nonlinear ordinary diff
Megacystis microcolon intestinal hypoperistalsis syndrome (MMIHS) is defined as a congenital visceral myopathy with genetic mutations. However, the etiology and pathophysiology are not fully understood. We aimed to generate a gene leiomodin-1a ( lmod1a ) modification technique to establish a ...
The stone burden is defined as the number and size of stones present. Stone burden is used to determine therapy such as lithotripsy. • The tips of the renal pyramids are high attenuation when the patient is dehydrated (see Fig. 15‐34). This normal finding of “white pyramids” should ...
(18) The volumetric flow rate in the fixed frame is defined as: Q= h 2rudr = 0 1 + βλ2 Dtβ −1 (1 + λ1α Dtα) − h4 8 ∂p ∂x + UHS h2 − 2hI1(mh) m I0 (mh) (19) The relationships of the wave frame (X, R), (U, V) moving with velocity c ...
