[Selective assessment of biomechanical properties of the lens capsule].

Unlabelled: The scientific and practical interest in studying the biomechanical characteristics of the lens capsule, on the one hand, is associated with its anatomical significance in modern microinvasive phaco surgery, and on the other hand, with investigation of the mechanisms of lens curvature changes during accommodation. Selective study of the biomechanical properties of the lens capsule aims to identify characteristics of various regions and surfaces of the capsule.

Purpose: This study is a comparative analysis of age-related changes in the biomechanical properties of the anterior (AC) and posterior (PC) lens capsules in humans.

[Application of parametric statistics to visual acuity data].

Unlabelled: ETDRS charts with logarithmic notation are widely used for measuring visual acuity in clinical studies worldwide. However, the distribution of measurement results often deviates from normal, limiting the applicability of parametric statistical methods, which are more powerful than the non-parametric ones. In cases of significant skewness, raw data can undergo power transformation with varying exponents (λ), as described by J.

Anatomical requirements for dacryocystorhinostomy ostium patency.

Purpose: To identify anatomical factors affecting the outcome of dcryocystorhinostomy (DCR).

Methods: The study included the results of dacryocystography in 73 patients after DCR: 37 cases of failed DCR and 36 cases of successful DCR. Biometric characteristics of the formed ostium were evaluated: the horizontal size of the bony "window" and the soft tissue part of the ostium, the vertical size of the bony "window" and soft tissue ostium, the height of the fragment of the remaining bone above and below the line of the common canaliculus, and the height of the "pocket" formed below the lower edge of the ostium.

Biochemical and Structural Diversification of C Photosynthesis in Tribe Zoysieae (Poaceae).

C photosynthesis has evolved independently multiple times in grass lineages with nine anatomical and three biochemical subtypes. Chloridoideae represents one of the separate events and contains species of two biochemical subtypes, NAD-ME and PEP-CK. Assessment of C photosynthesis diversification is limited by species sampling.

[Features of accumulation of chemical elements in the volume of the lens in senile cataract].

Purpose: This study provides a detailed analysis of the bioinorganic chemical composition of lens substance in patients with senile cataract using classical and spatial statistics methods.

Material And Methods: The study included 30 isolated human lenses. The light scattering ability (LSA) of the lens substance was evaluated using an original method.
