A PMMA-Based Microfluidic Device for Human Sperm Evaluation and Screening on Swimming Capability and Swimming Persistence

Micromachines, 2020
The selection of high-quality sperm is essential to the success of in vitro fertilization (IVF). As human cervical mucus has a high viscosity, without enough swimming persistence, human sperm clouds cannot arrive at the ampulla to fertilize the egg.

Round spermatid injection into human oocytes: a systematic review and meta-analysis

Asian Journal of Andrology, 2021
Many azoospermic men do not possess mature spermatozoa at the time of surgical sperm extraction. This study is a systematic review and meta-analysis evaluating outcomes following round spermatid injection (ROSI), a technique which utilizes immature ...

Ternary Synergy in Layered Double Hydroxides for Efficient and Stable Nitrate Reduction

Advanced Functional Materials, EarlyView.
Ternary CuZnFe LDH enables efficient electrocatalytic nitrate‐to‐ammonia conversion via controlled in situ reconstruction: zinc leaching creates porous active sites, copper reduced to metallic copper, while iron oxide keeps stable. Synergistic Cu‐Fe redox coupling drives tandem catalysis (nitrate→nitrite→NH3), achieving 95% Faraday efficiency and ...

human capital, fertility and growth [PDF]

, 2008
The transition from stagnation to growth has been the subject of intensive research in recent years. The rise in the demand for human capital and the associated decline in population growth have been identified as the prime forces in the movement from an epoch of stagnation to a state of sustained economic growth.

Human rights to in vitro fertilization

International Journal of Gynecology & Obstetrics, 2013
AbstractThe Inter‐American Court of Human Rights (the Court) has ruled that the Supreme Court of Costa Rica's judgment in 2000 prohibiting in vitro fertilization (IVF) violated the human right to private and family life, the human right to found and raise a family, and the human right to non‐discrimination on grounds of disability, financial means, or ...

Advanced Oral Delivery Systems for Nutraceuticals

Advanced Healthcare Materials, EarlyView.
Emerging delivery technologies are explored to overcome barriers to oral nutraceutical absorption. Traditional carriers are compared with novel platforms including biodegradable polymers, MOFs, MPNs, and 3D printing. These systems enhance bioavailability, control release, and enable personalized nutrition.
