随着辅助生殖技术(assisted reproductive technology，ART)的不断发展，特别是卵胞质内单精子显微注射技术(intracytoplasmic sperm injection，ICSI)和男科显微外科取精术(microdissection testicular sperm extraction，micro-TESE；testicular sperm aspiration，TESA)的临床应用，严重男性不育包括严重 ...

Laminated Strand Lumber creates straighter walls, making it easier to install cabinetry, millwork and tile. There are no knots, splits or voids and the strength and stiffness properties of laminated strand lumber (LSL) exceed those of traditional lumber.

This study reports use a new micro-straw (LSL straw) for freezing few spermatozoa for intracytoplasmic sperm injection (ICSI). Semen samples from 22 fertile donors were collected, and each semen sample was diluted and mixed with cryoprotectant in a ratio of 1:1, and then frozen using three different straws such as LSL straw (50–100 μl ...

2022年2月18日 · Micro-straw, Cryoplus, and LSL carriers are all efficient means of freezing rare human spermatozoa. However, the Micro-straw carrier is more economical, safe, and user-friendly.

Objectives: Is the micro-straw cryopreservation carrier more effective for cryopreserving rare human spermatozoa compared with the Cryoplus and a new micro-straw (LSL straw) carriers? Materials and methods: This study involves 93 samples from healthy sperm donors and 40 samples from patients diagnosed with oligospermia, asthenospermia ...

2016年2月4日 · Objectives: Is the micro-straw cryopreservation carrier more effective for cryopreserving rare human spermatozoa compared with the Cryoplus and a new micro-straw (LSL straw) carriers?

Laminated Strand Lumber (LSL) LSL is similar to other SCL except that it consists of flakes (much like OSB). For comparison, LVL is made from multiple layers of veneers bonded together. This difference in the creation process causes LSL to provide a "rougher" surface texture than LVL and similarly built SCL beams.

The LSL Cobra Micro maintains efficient AC Emergency Power to operate all emergency lighting fixtures at “full-light” output after the transfer is complete, providing superior dependability and security to commercial/industrial environments in a small footprint.

Microllam® LVL beams work well in applications all over the house. They can easily be built-up on site to reduce heavy lifting. No matter where they’re used, they install quickly with little or no waste. We do not sell products direct. For quotes, pricing and availability use our Where to Buy tool to find a dealer near you.

2023年2月18日 · You will be able to create your LSL files with syntax highlighting and use external tools to preprocess the script (for #includes) and to optimize your scripts using LSL-PyOptimizer. You could use the Firestorm preprocessor but I feel like doing all your code preprocessing, editing, and optimizing externally from Firestorm has a better workflow ...
