Dynamic tear meniscus parameters in complete blinking: insights into dry eye assessment.

Aim: To investigate the relationship between dynamic tear meniscus parameters and dry eye using an automated tear meniscus segmentation method.

Methods: The analysis of tear meniscus videos captured within 5s after a complete blink includes data from 38 participates. By processing video data, several key parameters including the average height of the tear meniscus at different lengths, the curvature of the tear meniscus's upper boundary, and the total area of the tear meniscus in each frame were calculated.

Therapeutic potential of anti-IL-1β IgY in guinea pigs with allergic asthma induced by ovalbumin.

Background: Interleukin-1 beta (IL-1β) plays pivotal roles in the progression of allergic airway inflammation. This study aims to determine whether the blockade of IL-1β can inhibit airway inflammation in guinea pigs with allergic asthma induced by the inhalation of aerosolized ovalbumin (OVA).

Methods: Healthy guinea pigs treated with saline were used as normal controls (group C).

Two phthalide dimers from the radix of Angelica sinensis.

The phytochemical investigation of extracts from the radix of Angelica sinensis yielded a new phthalide dimer, 3,3'Z-6.7',7.6'-diligustilide, along with a known dimer, levistolide A.
