purpose: to evaluate the efficacy of radial optic neurotomy (ron) combined with or without intravitreal triamcinolone acetonid (ivta) injection in the management of central retinal vein occlusion (crvo). methods: this non-randomized clinical trial was conducted on 23 patients with crvo, who underwent ron with or without ivta injection. preoperative and postoperative best corrected visual acuity...

[1] Using the Moon Mineralogy Mapper(M), we examine the Marius Hills volcanic complex for the first time from 0.46 to 2.97 mm. The integrated band depth at 1 mm separates the mare basalts on the plateau in two units: (1) a strong 1 mm band unit of localized lava flows within the plateau that has similar olivine‐rich signatures to those of the nearby Oceanus Procellarum and (2) a weaker 1 mm ban...

BACKGROUND Knee valgus and varus morbidity is at the second top place in children lower limb deformity diseases. It may cause abnormal stress distribution. The magnitude and location of contact forces on tibia plateau during gait cycle have been indicated as markers for risk of osteoarthritis. So far, few studies reported the contact stress and force distribution on tibial plateau of valgus kne...

Twenty-seven species of Odonata were collected in the present survey in the freshwaters of South-Eastern Iran, Kerman province, in contrast to 11 species that were recorded previously from this region. In this study, 528 specimens were collected from more than 30 sites in Kerman province during 2006-2008. It seems that in this region due to its special biogeographic conditions, species diversit...

OBJECTIVE The methods most used for patellar height measurement were compared with the plateau-patella angle method. METHODS A cross-sectional study was conducted, in which lateral-view radiographs of the knee were evaluated using the three methods already established in the literature: Insall-Salvati (IS), Blackburne-Peel (BP) and Caton-Deschamps (CD). These were compared with the plateau-pa...

Methacholine provocation tests are aimed at determining bronchial responsiveness. Recent investigations stress the importance of considering the entire log-dose response curve, yielding not only the provocative dose producing a 20% change in forced expiratory volume in one second (FEV1) (PC20), but also the plateau value and the steepest slope of the curve (reactivity). In three control subject...

The deep piriform region has an unusually high seizure susceptibility. Voltage imaging previously located the sites of epileptiform discharge onset in slices of rat piriform cortex and revealed the spatiotemporal pattern of development of two types of electrical activity during the latent period prior to discharge onset. A ramplike depolarization (onset activity) appears at the site of discharg...

BACKGROUND We describe two cases of recurrent acute angle-closure attack in patients with plateau iris syndrome after cataract extraction. Argon laser peripheral iridoplasty and cataract extraction have been used to reduce the occurrence of acute angle-closure attack in plateau iris syndrome although the risk cannot be completely eliminated. There is no consensus on the long term management of ...

Early attempts at classifying tibial plateau fractures by Palmer in 1951 [25], Hohl and Luck in 1956 [15], and Hohl in 1967 [15] recognized some of the major themes common to many classification systems for these fractures: split of a condyle, subchondral depression, and comminuted bicondylar involvement. Schatzker et al. published their classification system in 1979 [29], deriving it from the ...

Both of the uplift of Qinghai-Tibet Plateau (QTP) and the development of East Asian monsoon system (EAMS) could have comprehensively impacted the formation and evolution of Arid Central Asia (ACA). To understand how desert plants endemic to ACA responded to these two factors, we profiled the historical population dynamics and distribution range shift of a constructive desert shrub Reaumuria soo...
