BACKGROUND AND STUDY AIMS The approach to small bowel preparation before capsule endoscopy (CE) is still suboptimal. PATIENTS AND METHODS One hundred eighty patients were randomly allocated to 3 groups. Patients in Group A took 250 mL 20% mannitol and 1 L 0.9% saline orally at 05:00 hours on the day of the procedure. In Group B the same preparation was taken at 20:00 on the day before, and at...

With approximately 250 000 marine species, the ocean is a vast reservoir of biodiversity and an abundant biological resource natural polymers microorganisms producing biopolymer-degrading enzymes.

PURPOSE To evaluate hemodynamic effects of mannitol infusion in patients with acute intracerebral hemorrhage. METHODS Thirty patients with acute intracerebral hemorrhage were enrolled. Transcranial doppler was used to detect variables of bilateral middle cerebral arteria (MCA) including mean velocity (Vm) and pulsitility index (PI) before and after 125 ml and 250 ml mannitol infusion (0, 30, ...

The wet tropical forest is, on the whole, a unique ecosystem in the world that is known to house the absolute highest number of species of both plants and animals. In this regard, it is enough to stress that the total number of flowering plant species currently known around the world is ~250 000, of which ~90 000 are of the rain forests of South America and Central America, and ~30 000 are of t...

BACKGROUND We conducted a randomized, placebo-controlled, double-blind trial to establish the efficacy of atovaquone-proguanil to prevent malaria with the goal of simulating weekly dosing in a human Plasmodium falciparum challenge model. METHODS Thirty volunteers randomly received 1 of the following dose regimens: (1) 250 milligrams of atovaquone and 100 milligrams of proguanil (250/100 milli...

Background. Oxidative stress in schizophrenia may be caused partially by the treatment of patients with antipsychotics. The aim of the study was to establish the effects of polyphenol compounds derived from berries of Aronia melanocarpa (Aronox) on the plasma lipid peroxidation induced by ziprasidone in vitro. Methods. Lipid peroxidation was measured by the level of thiobarbituric acid reactive...

BACKGROUND/AIMS Inadequacy of dialysis is associated with morbidity and mortality in chronic hemodialysis (HD) patients. Blood flow rate (BFR) during HD is one of the important determinants of increasing dialysis dose. However, the optimal BFR is unclear. In this study, we investigated the impact of the BFR on all-cause mortality in chronic HD patients. METHODS Prevalent HD patients were sele...

BACKGROUND Increased concentrations of cell-free DNA have been found in several disorders and have been interpreted as evidence of increased rates of cell death or turnover. Evidence from in vitro and animal experiments suggests that DNA may play a role in the pathogenesis of rheumatoid arthritis (RA). METHODS We measured cell-free DNA in plasma and serum from patients with RA and healthy con...

Glyoxylate dehydrogenase (glyoxylate:NAD+ oxidoreductase) was purified 600-fold in three steps from crude extracts of the fungus Sclerotium rolfsii (Corticium rolfsii Curzi). Two of the purification steps involved dye-affinity chromatography. The enzyme is a tetramer of Mr 250 000, with identical subunits of Mr 57 000. Inhibition studies suggest that there is one essential thiol group per activ...

Data from the annual general report of the Venereal Disease Control Centre (VDCC) in a state with a population of approximately 1 250 000 people (in 1977), of whom about 1 100 000 live within 25 miles of the centre of Adelaide, the capital city, are presented.
