Comparison between a new device for the semen quality analysis and the manual microscopic evaluation in a not specialistic clinical laboratory

Advances in Laboratory Medicine
Semen analysis investigates different parameters of human semen with a high relevance in fertility workup, confirmation of sterility by post vasectomy, in pathologies follow-up such as varicocele and in all cases where sperm preservation is required ...

Peranan Antioksidan Dalam Pembekuan Semen [PDF]

, 2009
Sperm plasma membrane was rich unsaturated fatty acid and vulnerable to peroxydative damage. Vulnerability sperm against lipid peroksidation could be caused by increased cold shock. The peroxydative processed alter the structure of.

Packed for Ossification: High‐Density Bioprinting of hPDC Spheroids in HAMA Toward Endochondral Ossification

Advanced Healthcare Materials, EarlyView.
Human periosteum‐derived cell spheroids bioprinted at high density within a hyaluronic acid matrix promote fusion and hypertrophic cartilage formation in vitro. Early encapsulation enhances spheroid interaction and matrix maturation, generating scalable cartilage templates intended for endochondral bone regeneration.

3D Soft Hydrogels Induce Human Mesenchymal Stem Cells “Deep” Quiescence

Advanced Healthcare Materials, EarlyView.
Three‐dimensional soft hydrogels mimicking the bone marrow niche induce deep quiescence in human mesenchymal stem cells. Unlike 2D culture, 3D matrices halt proliferation, regulate cell‐cycle and quiescence markers, and downregulate mTORC1 signaling, preserving stem cell phenotype and therapeutic potential ex vivo.

Liproxstatin-1 improves boar sperm quality during in vitro liquid preservation at 17°C, associated with reduction of oxidative stress and ferroptosis markers

Frontiers in Veterinary Science
ObjectiveThe plasma membrane of boar sperm is notably enriched in polyunsaturated fatty acids (PUFAs). During extended liquid storage of boar semen at 17°C, reactive oxygen species (ROS) derived from lipid peroxidation progressively accumulate within ...

Rapid Fabrication of Self‐Propelled and Steerable Magnetic Microcatheters for Precision Medicine

Advanced Materials, EarlyView.
A rapid Joule heating fabrication method for the production of self‐propelling, adaptive microcatheters, with tunable stiffness and integrated microfluidic channels is presented. Demonstrated through three microrobotic designs, including a steerable guiding catheter, an untethered wave‐crawling TubeBot, and a distal‐end propelled microcatheter, it was ...

Recent advances in semen preservation.

Journal of the South African Veterinary Association, 1976
While the horizons for cryobiology may be bright and granted, tremendous strides have been made in the area of artifical insemination(AI), it is evident that only dairy cattle AI with frozen semen has achieved industrial application. Beef cattle AI has been hampered by the lack of suitable techniques for oestrous control.
