To the Editor: Photo-activated chromophore for keratitis crosslinking (PACK-CXL) 1-4 may become an attractive treatment for developing and emerging countries where access to ophthalmic care and medical equipment is limited.5 PACK-CXL treatment has the potential to be performed at the slit-lamp within 3 to 5 minutes.3 We have addressed a remaining concern: is the stromal riboflavin distribution ...
Background and Aims: Given the role of blood flow restriction in causing more hemodynamic stress, the aim of the present study was to investigate the effect of blood flow restriction on the metabolic rate and substrate oxidation during and after high-intensity intermittent exercise (HIIE) in male active students. Method: For this purpose, 10 male active students, selected and in a cross-over de...
BACKGROUND The 2005 Guidelines for Cardiopulmonary Resuscitation and Emergency Cardiovascular Care changed the previous ventilations-to-chest-compression algorithm for bystander cardiopulmonary resuscitation (CPR) from 2 ventilations before each 15 chest compressions (2:15 CPR) to 30 chest compressions before 2 ventilations (30:2 CPR). It was acknowledged in the guidelines that the change was b...
AIMS A set of five tests were developed and tested for their ability to confirm the identity of C difficile colonies within 30 minutes. METHODS The relevant substrates were incorporated into four filter paper squares attached to a plastic carrier (Diffstrip), five enzymes/products (prolyl aminopeptidase, galactosidase, leucine aminopeptidase, acid phosphatase and indole). The strips were inoc...
INTRODUCTION Phosphatidylserine (PS) externalization is regarded as one of the earliest hallmarks of cells undergoing programmed cell death. We studied the use of labeled human recombinant annexin-V, a protein selectively binding to PS, to detect cardiomyocyte death in an in vivo mouse model of cardiac ischemia and reperfusion (I/R). METHODS AND RESULTS I/R was induced in mouse hearts by liga...
Determination of normal gastric emptying time and small intestinal transit time are useful in detecting gastrointestinal motility disorders and partial obstructions of the pylorus or small intestine. This study was conducted to evaluate iodixanol as a contrast agent in the gastrointestinal tract in New Zealand White rabbit. Twelve clinically healthy adult rabbits were prepared and kept for two ...
Adults mongrel dogs, weighing from 18 to 24 kg, were used. The entire small bowel was procured and flushed with cold lactated Ringer's solution containing heparin through the superior mesenteric artery. The intestinal lumen was also irrigated with the same solution. After the graft was preserved in the cold lactated Ringer's ,olution for 24 hours, it was transplanted orthotopically into the ,;a...
in the area of vocabulary teaching and learning although much research has been done, only some of it has led to effective techniques of vocabulary teaching and many language learners still have problem learning vocabulary. the urge behind this study was to investigate three methods of teaching words. the first one was teaching words in context based on a traditional method of teaching that is,...
The aim of this study was to investigate the usefulness of lubiprostone for bowel preparation and as a propulsive agent in small bowel endoscopy. Six healthy male volunteers participated in this randomized, 3-way crossover study. The subjects received a 24 μg tablet of lubiprostone 60 minutes prior to the capsule ingestion for capsule endoscopy (CE) and a placebo tablet 30 minutes before the ca...
