Intracytoplasmic sperm injection (ICSI) was successful in the mouse when a piezo-driven
micropipette was used instead of a mechanically driven conventional pipette. Eighty percent of …

Objectives The objective of this study was to investigate changes in physical activity (PA)
between January (before the COVID-19 epidemic) and April (during the COVID-19 epidemic) …

Genomic imprinting occurs in both male and female gametes during gametogenesis, but the
exact time when imprinting begins and ends is unknown. In the present study we injected …

To determine whether spermatozoa must be structurally intact before microsurgical injection
into oocytes for normal fertilization, intact spermatozoa, as well as sperm heads separated …

Fiber-shaped H-aggregates with lengths of up to 300 μm are synthesized by self-assembly
of thiacyanine (TC) dye molecules in solution. Photoluminescence (PL) images and spatially …

A panel of radiochemicals has enabled in vivo positron emission tomography (PET) of tau
pathologies in Alzheimer's disease (AD), although sensitive detection of frontotemporal lobar …

Intracytoplasmic sperm injection (ICSI) has wide clinical application. In order to achieve good
results with this method, it is important to restrict the possibility of oocyte injury as much as …

This study shows that the nucleus of the secondary spermatocyte can participate in
syngamy and normal embryonic development. Spermatogenic cells were released from the …

Objective To determine whether the outcome of IVF can be predicted by acridine orange (AO)
nuclear fluorescence of sperm. Design Based on the fact that AO nuclear fluorescence …

Tau accumulation in the brain is a pathologic hallmark of Alzheimer disease and other
tauopathies. Quantitative visualization of tau pathology in humans can be a powerful method as a …
