abstract appendiceal intussusception is a very rare cause of abdominal colic in childhood. this paper reports a reducible appendiceal intussusception in the barium enema in a girl and reviews articles in pubmed.

Today, due to the natural decline of oil exploitation, the use of methods of oil recovery, has made significant progress. However, these methods are accompanied by accumulation and deposition of mineral deposits in oil field installations. In the present study, aqueous solutions, strontium sulfate, barium sulfate, manganese sulfate and nickel sulfate are studied, in terms of EUNIQUAC model and ...

Alveolarization of the barium sulfate and subsequent retention of barium sulfate for years was demonstrated in three patients in whom dilute suspension of barium sulfate in water was used for bronchography. Pathologic examination in one patient showed barium sulfate within macrophages in the alveolar spaces and walls and in the perivascular and peribronchial interstitium. Since the residual bar...

The effect of tungsten erosion, transport, and redeposition on the operation of dispenser hollow cathodes was investigated in detailed examinations of the discharge cathode inserts from 8200 h and 30 352 h ion engine wear tests. Erosion and subsequent redeposition of tungsten in the electron emission zone at the downstream end of the insert reduce the porosity of the tungsten matrix, preventing...

Halloysite nanotubes (HNTs) were investigated as a platform for tunable nanoparticle composition and enhanced opacity in poly(methyl methacrylate) (PMMA) bone cement. Halloysite has been widely used to increase the mechanical properties of various polymer matrices, in stark contrast to other fillers such as barium sulfate that provide opacity but also decrease mechanical strength. The present w...

BACKGROUND Symptom relief post pneumatic dilation is traditionally used to assess treatment success in achalasia patients. Recently, we showed that symptom relief and objective oesophageal emptying are concordant in about 70% of patients, while up to 30% of achalasia patients report near complete symptom relief despite poor oesophageal emptying of barium. AIMS We now report the results of lon...

A barium enema is a diagnostic and therapeutic procedure commonly used for colon and rectum problems. Rectal perforation with extensive intra- and/or extraperitoneal spillage of barium is a devastating complication of a barium enema that leads to a significant increase in patient mortality. Due to the low number of reported cases in recent scientific literature and the lack of experience with t...

Context. Barium stars show enhanced abundances of the slow neutron capture (s-process) heavy elements, and for this reason they are suitable objects for the study of s-process elements. Aims. The aim of this work is to quantify the contributions of the s-, r-and p-processes for the total abundance of heavy elements from abundances derived for a sample of 26 barium stars. The abundance ratios be...

OBJECTIVE To assess the efficacy of barium meal examinations in managing patients with dyspepsia in general practice. DESIGN Prospective study by questionnaires completed by general practitioners before and within three to six months after the barium meal examination. Information was requested about the patients' symptoms, current treatment, reason for requesting the examination, and the work...

Wheat is the world's second most produced grain because of its high consumption rate, easy growth, multipurpose use and important role in the human diet. Every year, abundant amounts of wheat hull are obtained after shell process of the wheat as a waste material. Wheat hull, a by-product of the food industry, has low economic value. The utilization of wheat hull ash in various areas of industry...
