background: in the light of various applications of uv laser in biological system, we have investigated the effect of picosecond uv laser radiation on silkworm bombyx mori. materials and methods: the eggs of nb4d2 of different stages were exposed to pico second pulse laser at 355 nm from nd:yag laser for different durations. results: due to irradiation alterations in crescent larval body markin...
Assisted Hatching (AH) is a technique performed after In Vitro Fertilization (IVF) and involves the artificial thinning or opening of the Zona Pellucida (ZP) prior to Embryo Transfer (ET) as an attempt to improve the probability of embryo implantation. AH can be performed by embryologists via mechanical, chemical, or laser-assisted means. A few studies suggest that a larger size of ZP opening/t...
nitric oxide (no) is a small molecule synthesized by most of mammalian cells with diverse biological activities including vasodilatation, host defense and wound healing. impaired wound healing is a common occurrence among diabetics and patients receiving glucocorticoid therapy. on the other hand the application of laser in biomedical area have been increased. thus, the current studies were desi...
BACKGROUND It is still debatable whether a full-thickness assisted hatching (AH) is better than the partial zona thinning. In this research, we used a mouse model to study the effect of partial and complete laser-AH on the rate of completely hatched blastocyst and their cell numbers. METHODS In experiment 1, mouse morulae had 0, 1, 2 or 3 full-thickness openings of 10 microns created in the z...
