In children born prematurely, the development of myopia is mainly influenced by anterior segment components, whereas hyperopia is mainly attributable to short AL. Astigmatism is primarily cornea-related. A combination of various optical components results in complicated refractive outcomes. The presence of ROP may be associated with significantly shorter ACD, thicker lens, and higher myopia and astigmatism. (ClinicalTrials.gov number, NCT01045616.).
EXPERIMENTAL Longitudinal (L) and long transverse (LT) directions of all the tempered materials were characterized by tensile strength, electrical conductivity, and SCC resistance. Rectangular tensile specimens with a gauge length of 25 mm (0.98 in.) and a width of 6.25 mm (0.25 in.) were used. Electrical conductivity was measured using the conventional four-probe method. Sample dimensions were 50 mm by 5 mm by 2 mm ABSTRACT A relationship between electrical conductivity and stress corrosion cracking (SCC) resistance of the 7,000-series Al-Zn-Mg alloys has been established, although only from the near-peak strength T6 temper to the overaged T73 tempered condition. The present work investigated whether this relationship exists for all periods of aging and for Al alloys with different compositions and grain structures.
With the method of retrograde transport of horseradish peroxidase, the present study demonstrated a topographical representation of the peripheral branches of the facial nerve within the rat facial nucleus. The labelled neurons relating to the different peripheral branches were characterized morphometrically with the aid of an image analyser system. While the results were in general agreement with the work of other investigators, a striking difference was observed in this study with respect to the spatial distribution of the labelled neurons of the cervical branch. In the latter, the cells of origin were derived from the dorsal parts of the lateral and intermediate division of the facial nucleus. The present study further demonstrated that the motoneurons giving rise to the respective peripheral branches of the facial nerve varied considerably in cell size. Thus, the neurons of the posterior auricular and the mental branches were significantly larger than those of the nasolabial and zygomatico-orbital branches. Another significant finding in this study was that the neurons supplying the mental branch were predominantly spindle-shaped. It is concluded that the heterogeneity in size and shape of the motoneurons in the facial nucleus is related to the topographical representation of the peripheral branches of the facial nerve.
The protective effects of antioxidant agents indicate that MOX, similar to BAC, causes oxidative stress-related cell damage. The results also inspired us to think about a "supplementary regimen" to increase safety and decrease the adverse effect in the treatment of corneal infections.
A total of 29 proven tuberculous spondylitis patients underwent MR studies. Gd-DTPA enhancement was performed in 10 patients. Contiguous 2 vertebral involvement, subligamental spread of paraspinal abscesses and cord indentation were observed in 93% of the cases. Destruction of the vertebral body occurred in 76%. Intermediate or low Tl signal intensity and high T2 signal intensity were observed by MR. A combination of these characteristic findings strongly suggests the diagnosis of tuberculous spondylitis. Gd-DTPA administration did not facilitate diagnosis. MR examination should be considered as the main imaging modality for patients with suspected tuberculous spondylitis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
