Integration of sperm motility and chemotaxis screening with a microchannel-based device.
BACKGROUND Sperm screening is an essential step in in vitro fertilization (IVF) procedures. The swim-up method, an assay for sperm motility, is used clinically to select the ideal sperm for subsequent manipulation. However, additional parameters, including acrosome reaction capability, chemotaxis, and thermotaxis, are also important indicators of mammalian sperm health. To monitor both sperm mo...
متن کاملA Microfluidic Device for Sorting Cancer Cells Based on Cell Motility
In this paper, we present a microfluidic device that allows for sorting of cancer cells based on their chemotactic migration speeds. We used breast cancer cell line cells to demonstrate cell seeding, migration and releasing in our microfluidic device. The ability of our device to provide subpopulations of chemotactically heterogeneous cancer cells should find useful applications in studying can...
متن کاملThe effect of an intra-uterine device on uterine motility in women and rhesus monkeys.
PRESENT understanding of human female reproductive physiology has largely been derived from the results of animal experimentation, and particularly from studies on the rhesus monkey. This is also true of our present knowledge of the possible modes of action of an intra-uterine device (IUD). Recent studies in the rhesus monkey have shown that an intra-uterine device is contraceptive in this spec...
متن کاملA Catheter-Based Acoustic Interrogation Device for Monitoring Motility Dynamics of the Lower Esophageal Sphincter
This paper presents novel minimally-invasive, catheter-based acoustic interrogation device for monitoring motility dynamics of the lower esophageal sphincter (LES). A micro-oscillator actively emitting sound wave at 16 kHz is located at one side of the LES, and a miniature microphone is located at the other side of the sphincter to capture the sound generated from the oscillator. Thus, the dyna...
متن کاملThe usefulness of the cervical range of motion device in the ocular motility examination.
OBJECTIVES To determine if the cervical range of motion (CROM) device, an instrument designed to assess the range of motion in the cervical spine, may be suited for accurately quantifying the magnitude of a patient's abnormal head posture, limitation of ductions, or range of single binocular vision at distance fixation. METHODS The CROM device was used to measure abnormal head postures in 10 ...
