The results of histochemical analysis of three muscles m. triceps brachii (MTB), m. longissimus thoracicus (MLT) and m. rectus femoris (MRF) of two groups of pigs created according to the genotypes MYF 4 are presented. Determination of MYF 4 genotypes was made by PCR method and for histochemical analysis was used 5 animals detected as homozygote MYF 4- AA type and 5 animals of heterozygote genotype myogenin-AB out of the total of 25 individual animals tested. The histochemical analysis proved that homozygotes AA have had bigger fat cells than heterozygotes AB in three studied muscles in average. The size of fat cells in MLT - 41.10?m or 38.50 ?m respectively dominated in both groups of animals. Percentage surface representation of interstitial tissues was higher in the studied muscles of heterozygote MYF 4-AB. The volume of ligaments was the highest in MRF (3.80% or 3.90% respectively) in both groups (myogenin - AA and AB). The average thickness was of three studied muscles muscle fibres higher at homozygote genotype myogenin-AA than in heterozygote myogenin-AB. The thickest fibres in both genotypes were in MRF (88.60 ?m, and 84.72 ?m respectively) and the lowest in MTB (73.30 and 69.40 ?m respectively). The highest values of muscle fibres thickness were detected in ?-White fibres. Their percentage surface representation corresponded to this in all three types of muscles of both studied genotype myogenin groups.

Background: The Blue bull (Boselaphus tragocamelus) is one of the biggest antelopes in Asia and is widely distributed in both the forests and adjoining villages with enough green grass.Methods: The present study was carried out on the mandible of six specimens of adult Blue bull (Boselaphus tragocamelus) of either sex. The biometrical parameters were measured by scale, graduated tape and digital Vernier’s caliper. The statistical analysis of the recorded data was done by independent samples t-Test with Systat Software Inc, USA and SPSS 16.0 version software.Result: The mandible of Blue bull consisted of two rami, i.e. horizontal and vertical rami. The two halves of this bone fused incompletely at the mandibular symphysis, situated at the midline. The average length of horizontal ramus of mandible was found to be 24.7±1.02 cm in female, which was significantly less (P less than 0.05) than that of males, where it was recorded as 35.4±1.97 cm. Similarly, the average thickness of vertical ramus at the base was found to be 0.53±0.001 cm in female, which was significantly less (P less than 0.05) than that of males, where it was recorded as 0.80±0.002 cm. The average cranio-caudal length of mandibular notch was found to be 1.32±0.01 cm in female, which was significantly less (P less than 0.05) than that of males, where it was recorded as 1.44±0.02 cm. Most of the biometrical observations on different parameters of mandible of Blue bull were having significantly (P less than 0.05) more values in males than females. Conclusion: Most of the biometrical observations on different parameters of mandible of Blue bull were having significantly (p less than 0.05) more values in males than females. The present gross and biometrical studies would be useful to the wild life professionals for determination of sex of this animal and solving vetero-legal cases related with this species.

Purpose: The aim of this study was to evaluate the correlations between fundus autofluorescence and morphologic parameters as well as visual function in patients with diabetic macular oedema treated with intravitreal ziv-aflibercept. Methods: A total of 34 eyes of 20 patients with untreated diabetic macular oedema received an intravitreal injection of ziv-aflibercept at baseline, and 1 and 2 months later. The baseline, 1-month, and two-month best corrected visual acuity determination, contrast sensitivity, spectral domain optical coherence tomography, mean central macular thickness, mean macular cube volume, mean macular cube average thickness, and fundus autofluorescence (decreased, normal, or increased; and single or multiple spots) were measured. Correlation analysis with a determination of Spearman’s rank correlation coefficient, regression analysis, agreement between investigators, and Friedman’s test were used for statistical analyses. Results: A direct correlation was observed between baseline fundus autofluorescence and macular cube average thickness at 1 month (r = 0.51, p = 0.020) and between fundus autofluorescence at 1 month and baseline macular cube average thickness (r = 0.50, p = 0.021). Regression analysis showed a coefficient of determination of 0.29 (p = 0.016) between baseline fundus autofluorescence and macular cube average thickness at 1 month. Conclusion: In patients with diabetic macular oedema, the pretreatment baseline degree of foveal fundus autofluorescence might be helpful in predicting macular cube average thickness in patients undergoing treatment with intravitreal ziv-aflibercept in the short term.

Periodontal Membrane

A tooth may be regarded as a rigid body, held in a rigid socket by a thin membrane— the periodontal membrane or pericementum —which fills the space between the tooth and the bone, and is attached to each. This membrane, whose average thickness is only 0.23 to 0.25 mm. (0.0091 to 0.0099 in.), is called upon to supply the tractions necessary to resist the forces applied in biting or chewing. An interesting problem in the theory of elasticity is thus suggested, namely, the determination of the displacement of the tooth and the strain and stress in the membrane, corresponding to the application of assigned forces to the crown of the tooth. We are obviously entitled to treat the problem mathematically as that of an infinitely thin membrane, but we shall have to make other simplifications in order to reduce the problem to a manageable form.

The theory of non-stationary flow has, been applied to the movement of water in the upper layers of the Pleistocene terrace on the western side of the river IJssel. A Fourier analysis of the movement of the water levels in the river and in several wells permitted calculation of the ratio of permeability to the storage coefficient of the soil. Assuming that the storage coefficient was o. I0 and the average thickness of the aquifer was I5 m, the average permeability was calculated to be 53 m/day. The discharge of water from the soil (0.8 cu m/day) can be calculated without knowing the thickness of the aquifer. The method can be used to calculate the amount of water needed for irrigation and the amount of water percolating from the hinterland to the river.
