An ODS column dynamically coated with zwitterionic bile acid derivative, 3-[(3-cholamidopropyl)-dimethylammonio]-1-propanesulfonate (CHAPS), was evaluated for direct injection determination of drugs in blood serum by HPLC. Polar functional groups such as sulfonate, ammonium and the three hydroxyl groups in CHAPS protruding towards an aqueous mobile phase formed a hydrophilic layer over the ODS ...

Obstructed defecation syndrome (ODS) is one of the most widespread clinical problems which frequently affects middle-aged females. There is a new surgical technique called stapled transanal rectal resection (STARR) that makes it possible to remove the anorectal mucosa circumferential and reinforce the anterior anorectal junction wall with the use of a circular stapler. This surgical technique d...

Inter-individual variability in weight gain and loss under energy surfeit and deficit conditions, respectively, are well recognized but poorly understood phenomena. We documented weight loss variability in an intensively supervised clinical weight loss program and assessed skeletal muscle gene expression and phenotypic characteristics related to variable response to a 900 kcal regimen. Matched ...

background: pathophysiology and treatment of obstructive defecation syndrome (ods) remains to be defined clearly. rectal hidden intussusceptions and voluminous hemorrhoids may be the cause. where conservative treatment is not effective, ods can be treated by starr or delorme operation. in some patients treatment of advance hemorrhoidal disease may resolve the syndrome. methods: 81 females out o...

The osmotic demyelination syndrome (ODS) is a central nervous system disorder that results from neuronal damage related to abrupt fluctuations of osmolality. In spite of the possibility of full or partial recovery in a considerable proportion of cases, ODS is still categorized as a disorder with poor prognosis that may lead to severe permanent disability or death. Efforts towards the better und...

Considering the structural role of type IV collagen (Col IV) in the assembly of the basement membrane (BM) and the perspective of mimicking its organization for vascular tissue engineering purposes, we studied the adsorption pattern of this protein on model hydrophilic (clean glass) and hydrophobic trichloro(octadecyl)silane (ODS) surfaces known to strongly affect the behavior of other matrix p...

Specifications for the AMPLICOR HIV-1 MONITOR kit indicate that the results are invalid if the optical densities (ODs) from the PCR-amplified sample that are between 0.1 and 2.3 units are out of sequence. However, among 11,904 assays, results were biased only when ODs of 0.2 to 2.0 units were out of sequence, reducing the rate of invalid results from 3.2 to 0.59%.

Based on the discussion of ODS (Operational Data Store), enterprise data environment features and data integration requirement, three granularity level data models of Web logs in e-commerce are analyzed. Further, data updating and collecting train of thought has been expressed which is realized by granularity manager. Finally, a model is put up, which integrates e-commerce data and other enterp...

BACKGROUND Obstructed defecation syndrome (ODS) occurs in about 7% of adults; it seems that the etiology of pelvic floor disorders is multifactorial. Pregnancy and childbirth damage to the pelvic nerve and muscles are proposed causes for this condition. The precise role of vaginal delivery (VD) is not clearly defined, although in recent studies association of pelvic floor disorder with Operativ...
