A 41-year-old man was referred with a complaint of visual loss in his left eye and his best corrected visual acuity was 20/80. Slit lamp examination showed arborizing conjunctival vessels and dry eye. Fundus examination and fluorescein angiography revealed a non-ischemic central retinal vein occlusion. Cardiovascular, rheumatologic, and hematologic work up showed no abnormal findings. An ascert...

results in all groups ischemic changes were apparently observed in hippocampus ca1 neurons. in two-vessel occlusion model, after 3 and 24 hours of reperfusions, ischemic cells accounted for 14.9% and 23.2%, respectively. in four-vessel occlusion model, after 3 and 24 hours of reperfusions, ischemic cells accounted for 7.6% and 44.9% (p < 0.0001), respectively. background an appropriate animal m...

purpose: to determine the frequency of risk factors for retinal vein occlusion (rvo) in patients referred to a private clinic in rasht during 1995-2001. methods: this cross-sectional study was conducted on all patients with rvo who were referred to the clinic. sex, age, hypertension (htn), cardiovascular diseases (cvd), diabetes mellitus (dm), hypercoagulable states, glaucoma, smoking, hyperlip...

OBJECTIVES This study explores the analytic implications of using questions about difficulty with daily activities that do not specify whether to consider assistance. METHODS For 1,054 Asset and Health Dynamics of the Oldest Old Study Wave 2 respondents, we compared responses to questions about difficulty without reference to assistance (ambiguous difficulty) to those about difficulty without...

BACKGROUND Low body temperature is considered neuroprotective in ischemic stroke, yet some studies suggest that low body temperature may also inhibit clot lysis and recanalization. We hypothesized that low body temperature was associated with persistent proximal middle cerebral artery (MCA) occlusion in patients with acute ischemic stroke presenting with symptoms of proximal MCA occlusion, sugg...

abstract background: peritoneal dialysis has a number of complications including increased blood glucose. although exercise has been suggested to resolve this complication, most patients are not active. the present study aimed at determining the effects of twice-weekly, 40-min sessions of pedaling on a stationary bicycle on mean fasting blood sugar (fbs) and 2-h postprandial blood sugar (ppbs) ...

OBJECTIVES In order to develop a multiplex RT-PCR assay using the GeXP analyser for the simultaneous detection of four different NA serotypes of H5-subtype AIVs, effective to control and reduce H5 subtype of avian influenza outbreak. DESIGN Six pairs of primers were designed using conserved and specific sequences of the AIV subtypes H5, N1, N2, N6 and N8 in GenBank. Each gene-specific primer ...

This article proposes using recycled aluminum, generating hydrogen in situ at low pressure, to power a 250 W electric bicycle with fuel cell (FC), increase the average speed and autonomy compared conventional battery. To generate hydrogen, aluminum–water reaction 6 M NaOH solution is used as catalyst. details parts of generation system, electronic configuration used, aluminum- reagent-loading p...
