this study was conducted to define the prevalence and types of corneal astigmatism in relation with corneal optical power, axial length, sex and patient age. 641 cataract patients were included in a descriptive study. complete eye examinations were included in a descriptive study. complete eye examinations were performed. the data were analysed by standard procedures including analysis of varia...

The length-tension relationship is a fundamental property of muscle. In its classic form, which is used in muscle models incorporated into studies of motor control, the length-tension relationship is measured during maximal activation via tetanic electrical stimulation in whole muscles or during high intracellular calcium levels in single muscle fibers. In this study, we measured the length-ten...

BACKGROUND AND AIM Estimation of small bowel length is of interest following the recent development of device-assisted enteroscopy. This new technology allows access to the deep small bowel, but rates of examination of the entire small bowel (total enteroscopy) differ between study populations. Variation in small bowel length could factor into this observed irregularity in total enteroscopy rat...

This contribution examines the macro quantitative features of 15 lowfrequency word classes. The relationship between word frequency classes and the sizes of the frequency classes obeys Altmann’s power law, and the sizes of lowfrequency word classes increase along with the increase of text length. The relationship between text length and the sizes of low-frequency word classes also obeys Altmann...

BACKGROUND Many studies have emphasized on fetal pinna measurements and morphologic features to use this structure as an additional marker for fetal chromosomal anomaly. OBJECTIVES To assess relationship between fetal pinna length and gestation age and develop a nomogram. To assess relationship between fetal pinna length and head circumference and biparietal diameter. METHODS Fetal pinna me...
