Background: There is some demand for nasogastric tube insertion in unconscious or ICU patients. Nasogastric tubes are generally made of flexible plastic materials, prone to twisting and deviation by the tracheal tube, when passing through the pharynx and esophageal opening, making it difficult to insert the NG-tube properly. We hypothesized that NG-tube insertion with help of guidewire can sign...

Central venous catheters are routinely placed in patients undergoing major surgeries where expected volume and hemodynamic disturbances are likely consequences. The incorrect positioning may give false central venous pressure (CVP) readings leading to incorrect volume replacement and other serious complications. 50 American Society of Anaesthesiologists grade II-IV patients aged 18-60 years wer...

BACKGROUND The prevalence of otitis media in Greenlandic children is one of the highest in the world. International studies have shown that otitis-prone children may benefit from tubulation of the tympanic membrane. However, it is unknown whether these results can be applied to Greenlandic children and trials on the effects of ventilation tubes in high-risk populations have, to our knowledge, n...

Mutations in the tumor suppressor gene TP53 are associated with a wide range of different cancers and may have prognostic and therapeutic implications. Methods for rapid and sensitive detection of mutations in this gene are therefore required. In order to make screening more effective, a commercially available TP53 genotyping microarray from Asper Biotech has been constructed by arrayed primer ...

Perceptual quality assessment of the videos acquired in wilds is vital importance for assurance video services. The inaccessibility reference with pristine and complexity authentic distortions pose great challenges this kind blind (BVQA) task. Although model-based transfer learning an effective efficient paradigm BVQA task, it remains to be a challenge explore <italic xmlns:mml="http://www.w3.o...

Peptide- and protein-protein dockings were carried out on β2-adrenergic receptor (β2AR) to confirm the presence of transmembrane helix 6 (TM6) at the interface region between two β2AR monomers, thereby its possible role in dimerization as suggested in numerous experimental and computational studies. Initially, a portion of TM6 was modeled as a peptide consisting of 23 residues and blindly docke...

Purpose: According to frequent needs to gastric decompression by nasogastric tube insertion during laparoscopic Cholecystectomy, the current comparative study was accomplished through single blind clinical trial considering both the presence and the absence of guide wire insertion. Materials and Methods: Twenty patients were selected for elective surgery of laparoscopic Cholecystectomywith ...

Objectives: To investigate the effect of enalapril, losartan, and surgical coronary revascularisation on endothelial function, and the role of the angiotensin converting enzyme (ACE) insertion (I)/deletion (D) polymorphism. Design: Randomised, controlled, blinded end point study. Setting: University tertiary referral cardiac centre. Patients and interventions: 49 men awaiting coronary artery by...
